A cutting layout and a cutting path 2 are planned on the mesh 1 according to the required cutting shape and the fiber trend distribution of the mesh 1, and a preset included angle is formed between the cutting path 2 and the fiber trend of the mesh 1; wherein, the fiber trend parameters of the mesh cloth 1 at least comprise two or three of warp direction, weft direction and slant direction.
In this embodiment, the fiber orientation parameters and fiber orientation distribution of the mesh 1 may be obtained by referring to a technical manual or manufacturer product description, and then the fiber orientation parameters and fiber orientation distribution information that are referred to are input into the first obtaining module, and the first obtaining module then sends an electrical signal to the controller, so that the controller makes a corresponding action.
More specifically, the warp direction refers to the direction in which the fibers of web 1 extend in the machine direction during manufacture, and is also generally the longest direction of web 1, and the warp fibers provide the primary strength and stability of web 1; weft refers to the direction in which fibers of web 1 extend perpendicular to the warp direction during manufacture; the oblique direction refers to the fiber extending direction of the mesh cloth 1 which is neither parallel nor perpendicular to the warp direction or the weft direction in the manufacturing process, and the oblique fibers can increase the elasticity and the stretchability of the mesh cloth 1, so that the mesh cloth has good deformability in multiple directions.
More specifically, the preset included angle is preferably ninety degrees, that is, the cutting edge of the vibrating blade is perpendicular to the warp 11 or weft 12 or oblique lines; when the blade edge of the vibrating blade is perpendicular to the warp 11 or the weft 12 or the oblique line, the cutting force of the vibrating blade to the warp 11 or the weft 12 or the oblique line can be fully applied to the warp 11 or the weft 12 or the oblique line; when an included angle is formed between the cutting edge of the vibrating knife and the warp 11 or the weft 12 or the oblique line, the component force of the cutting force of the vibrating knife to the warp 11 or the weft 12 or the oblique line along the direction perpendicular to the warp 11 or the weft 12 or the oblique line can be fully applied to the warp 11 or the weft 12 or the oblique line, and under the condition that the cutting force of the vibrating knife to the warp 11 or the weft 12 or the oblique line is unchanged, the cutting efficiency is obviously maximum when the cutting edge of the vibrating knife is perpendicular to the warp 11 or the weft 12 or the oblique line.
In the use process, firstly, the mesh cloth 1 is placed at the top of a conveyor belt, then the mesh cloth 1 is transported to a proper position through the conveyor belt, then the fiber trend parameters and the fiber trend distribution of the mesh cloth 1 are obtained through a first obtaining module, then the cutting layout and the cutting path 2 are planned on the mesh cloth 1 through a controller according to the shape required to be cut and the fiber trend distribution of the mesh cloth 1, a preset included angle is formed between the cutting path 2 and the fiber trend of the mesh cloth 1, and then the vibrating knife is driven to move along the cutting path 2 and vibrate up and down along the vertical direction so as to complete the cutting of the mesh cloth 1. Therefore, by ensuring that a proper included angle is formed between the vibrating knife and the mesh cloth 1, the abrasion of the vibrating knife can be reduced, the service life can be prolonged, and the cutting efficiency can be improved.
It can be understood that, since the shape of the mesh 1 to be cut is mostly shaped, when the cutting layout and the cutting path 2 are planned on the mesh 1, a simulation mode can be performed by a computer to find out the cutting layout with the cutting path 2 and the warp 11, the weft 12 and the oblique line being perpendicular most.
When cutting on the vertical mesh cloth 1, the cutting path 2 is firstly obtained, the edge detection algorithm is used for extracting the edge information of the cutting path 2, according to the fact that the cutting path 2 is a closed contour, the Sobel operator is used for obtaining the angle information of the edge pixel points, specifically, the gradient value of the edge pixel points in the horizontal coordinate direction and the gradient value of the edge pixel points in the vertical coordinate direction are calculated, the angle value of the pixel points is determined by using a trigonometric function, and the angle direction is symmetrical, so that the obtained angle value is 0 to 180.
After the computer simulation of the cutting path 2 in fig. 1, as shown in fig. 2, when the angle value is 0, the number of corresponding pixels is the largest, which illustrates a cutting layout in which the cutting path 2 in fig. 1 is the largest vertically on the vertical mesh 1 when the rotation angle value is 0.
When cutting a mesh 1 with an included angle of X, firstly, acquiring a cutting path 2, extracting edge information of the cutting path 2 by using an edge detection algorithm, and obtaining angle information of edge pixels by using a Sobel operator according to the fact that the cutting path 2 is a closed contour and particularly calculating a gradient value of the edge pixels in the abscissa direction and a gradient value of the edge pixels in the ordinate direction, and determining the angle value of the pixels by using a trigonometric function, wherein the angle value of the obtained angle value is 0-180, and the canvas can be corrected by rotating 0 to (180-X) degrees; and selecting the angle value with the largest corresponding ordinate as a rotation correction angle value, and rotating according to the obtained angle value, so that the cutting path 2 is perpendicular to the fiber direction of the mesh cloth 1 as much as possible.
In some embodiments, the strip-shaped material cutting device is configured to further include a second acquisition module for acquiring the mesh 13 shape of the mesh cloth 1;
The controller is further configured to:
When the vibrating blade moves along the cutting path 2, the blade tip direction of the vibrating blade is adjusted to ensure the integrity of the shape of the mesh 13.
Specifically, in this embodiment, the mesh 13 shape of the mesh 1 may be obtained by referring to the manufacturer's product description, and then the information of the referred mesh 13 shape is input to the second obtaining module, and the second obtaining module then sends an electrical signal to the controller, so that the controller makes a corresponding action.
More specifically, common mesh 13 shapes include circular, oval, hexagonal, diamond, triangular, irregular patterns, etc., wherein circular mesh is the most common mesh 13 shape, and the size and density of the circular mesh can be adjusted according to the ventilation property and the support requirement of the shoe; oval meshes are commonly used in areas where more directional breathability is desired, such as toe or heel portions; hexagonal meshes are used to provide balanced structural stability and breathability, commonly used in upper designs where balanced strength and ventilation are required; diamond-shaped meshes are common in some sports shoes, provide good stretchability and resilience, and are suitable for the type of shoes which need to dynamically adapt to foot sports; triangular meshes are less common but are used in some designs to provide additional structural support or unique visual effects; irregular meshes are commonly used in some high-end athletic shoes or fashion footwear styles to achieve a particular aesthetic or functional effect.
In use, when the mesh 13 is cut by the vibrating knife, the cut mesh 13 is poor in structural stability, and the corresponding function is lost mostly, so that the shape of the mesh 13 is complete, and the cutting of the mesh 13 is reduced as much as possible by adjusting the knife tip direction of the vibrating knife when the vibrating knife moves along the cutting path 2.
In a further embodiment, to further ensure the integrity of the mesh 13, the controller may be further configured to plan the cutting layout and the cutting path 2 on the web 1 according to the desired cut shape, the shape of the mesh 13 and the fiber orientation distribution of the web 1, and to provide a predetermined angle between the cutting path 2 and the fiber orientation of the web 1.
In this embodiment, the simulation mode can be performed by a computer, so as to find out a cutting layout which not only meets the requirement that the cutting path 2 is more vertical to the warp 11, the weft 12 and the oblique lines, but also meets the requirement that the mesh 13 is least damaged, so that on one hand, the abrasion of the vibrating knife can be reduced, the service life can be prolonged, and on the other hand, the normal function of the mesh 13 can be ensured.
In other embodiments, the controller is further configured to:
In the process that the vibrating blade moves along the cutting path 2, when the cutting path 2 is a straight line or an arc line, the travelling speed of the vibrating blade is increased.
In particular, in this embodiment, when the cutting path 2 is a straight line or an arc line, it is explained that the movement direction of the vibrating blade is clear, and in order to improve the efficiency in cutting, the cutting time of the vibrating blade on the cutting path 2 of the straight line or the arc line can be shortened by increasing the traveling speed of the vibrating blade.
In other embodiments, the controller is further configured to:
in the process of moving the vibrating blade along the cutting path 2, when the cutting path 2 is suddenly changed, the traveling speed of the vibrating blade is reduced.

In other embodiments, the case that the cutting path 2 is suddenly changed is set to further include that part of the cutting path 2 is a U-shaped structure 23, the U-shaped structure 23 has a connection portion and two extension portions symmetrically disposed about the connection portion, and a ratio between a length of the extension portion and a length of the connection portion is greater than a preset value, and the preset value is greater than 1.
Specifically, in this embodiment, the preset value is a set value; for example, the preset value may be set to three; when the ratio between the length of the extension portion and the length of the connection portion is greater than three, it means that the length of the extension portion is at least three times the length of the connection portion, and the U-shaped structure 23 is an elongated structure, and when the vibrating blade cuts along the U-shaped structure 23, the shape of the U-shaped structure 23 determines that the vibrating blade is easy to bend or break, so that the travelling speed of the vibrating blade is reduced to achieve more accurate cutting.
