Description

Narrow material crop auxiliary device and bag sealer

Technical Field

The invention belongs to the field of plate edge sealing equipment, and particularly relates to a narrow material end cutting auxiliary device and an edge sealing machine.

Background

In the manufacturing process of furniture, an edge sealing machine is needed to be adopted to carry out edge sealing treatment on the outer edge of the plate so as to improve the service performance of the plate. The edge bonding machine is used for conveying a plate through a chain block, two rows of fixing pressing wheels which are arranged in a staggered mode are arranged above the plate and used as an aid, and the center distance between every two adjacent fixing pressing wheels in the same row is 46 mm; the end cutting device is arranged on the inner side of the chain block relative to the edge bonding machine and is used for cutting the end along one side face of the front end of the plate conveying machine, so that the plate needs to be kept perpendicular to the chain block in the end cutting process. Most of existing furniture boards are rectangular structures and comprise long edges and short edges, the outer corners of the edges and the edges of some boards are rounded/chamfered, the length of the short edges of the boards is generally 60mm at the minimum in conventional edge sealing operation, and the boards with the length of the short edges being smaller than 60mm are called narrow boards or narrow boards in the field. In the plate edge sealing process, when a plate is conveyed to the head cutting device through the chain block, the baffle plate of the head cutting device is close to and positioned at the conveying front end of the plate, the close action of the baffle plate is accompanied by that the plate bears a resistance at the end corner part of the inner side of the chain block, only a small part of the plate with a small size extends out of the chain block and is positioned on the inner side of the chain block so as to facilitate the edge sealing and head and tail cutting operations, and most of the plate is positioned on the outer side of the chain block. For narrow materials with the edge sealing width smaller than 60mm, due to the size attribute of the fixed pinch rollers of the edge sealing machine, the center distance between two adjacent fixed pinch rollers is 46mm, each narrow material can only contact with three fixed pinch rollers at most, the contact between the fixed pinch rollers and the plate is too little, the plate cannot be completely stabilized, when the baffle is closed, the part (mainly represented as the outer part of the chain block) of one side of the plate, which is far away from the baffle, can perform inertial motion, the baffle is closed to the plate and positioned, the plate cannot be vertically balanced relative to the conveying direction, the plate can be shifted in the end cutting process, the end cutting is not parallel and level, even the plate is cut and damaged, and the product quality is influenced, therefore, manual edge sealing is needed for most narrow materials. And the manual edge sealing is adopted, so that the labor cost is increased, the production efficiency is difficult to improve, and meanwhile, the quality stability of the plate is difficult to ensure through manual operation. For enterprises, special edge banding machines are purchased, so that the enterprise cost is increased, and particularly, the cost pressure of medium and small enterprises is more obvious. If reform transform the bag sealer, because the compact structure of bag sealer, reform transform it and guarantee not influence production and the matching machine original function is more difficult, for example add fixed pinch roller, it is difficult to adjust the packing force of the fixed pinch roller pair panel that adds and original fixed pinch roller keep unanimous to be difficult to adjust, and the too little effect that can not reach of packing force regulation, the packing force is adjusted too greatly and can cause the indentation even crush damage panel to panel. Therefore, how to avoid the displacement phenomenon of the narrow material in the end cutting process and realize the mechanization of the narrow material edge sealing are problems to be solved urgently.

The pressure detection means is used to detect whether the fixed pinch rollers 44 are subjected to pressure and the number of fixed pinch rollers 44 that are simultaneously subjected to pressure. According to the newton's third law, when the fixed pinch roller 44 applies pressure to the plate 5, the fixed pinch roller 44 is pressed by the plate 5, so that it can be determined how many fixed pinch rollers are acting on each plate passing through the pressure detection device by detecting, and further, it is determined whether the detected plate belongs to a narrow material, for example, if the pressure detection device detects that less than 3 fixed pinch rollers 44 are simultaneously pressed, it can be considered that less than or equal to 3 fixed pinch rollers 44 are in contact with the plate, and at this time, the plate can be considered to be a narrow material; for another example, if more than 3 fixed press wheels 44 are pressed at the same time, it can be considered that more than 3 fixed press wheels 44 are in contact with the sheet, and at this time, the sheet is considered to have a larger width and is not a narrow material.

In some preferred embodiments, the edge bonding machine further includes a control system (not shown in the drawings), the control system is connected to the pressure detection device and the electric general control system, and the pressure detection device sends detection information (specifically, information about the number of the fixed pressing wheels 44 under pressure) to the control system for analysis; when the number of the fixed pinch rollers subjected to pressure is less than or equal to 3, the control system sends an instruction to the electric main control system, and the electric main control system controls the narrow material head cutting auxiliary device to act to assist in the head cutting process; when the number of the fixed pinch rollers which are simultaneously pressed is more than 3, the control system does not send a command, and the narrow material cropping auxiliary device is kept in a state of being turned and turned down by a stop (see fig. 2).

From this, whether detect panel and belong to the narrow material through pressure measurement, automatic control narrow material crop auxiliary device's work need not the manual work and triggers narrow material crop auxiliary device work according to the banding width of panel, improves work efficiency.
