Abstract

It's a vertical cord fabric cutting machine which is composed of a frame, a control box, a transmitting cloth rewinder roll and a cutting device. The transmitting cloth rewinder roll which is driven by a servomotor is equipped on top of the frame, and a length-measuring wheel and a coder installed coaxially are equipped above the transmitting cloth rewinder roll; the cutting device is installed on one side of the main frame composed of a knife holder, a rotary guideway, a transmitting cloth pushing block and a clamping mechanism; the cutoff knife is driven by the rodless cylinder; the transmitting cloth pushing block is equipped above the cutoff knife, and the knife holder can rotate on the rotary guideway; the front end of the sliding block of the clamping mechanism is processed with a knife trough. The cutting length is input by the operator via a touch screen, and the cutting angle is confirmed by adjusting the relative position of the knife holder and the rotary guideway. The cylinder of clamping mechanism drives the sliding block to move forwards to lift the transmitting cloth pushing block, and the cutoff knife cuts off the cord fabric along the knife trough of sliding block. The utility model features in simple structure, accurate control, high accuracy of fixed-length and cut-off and low failure rate of equipment; it adopts the cutoff knife driven by the rodless cylinder for repeatedly cutting, and the work efficiency is evidently raised.

Description

The vertical cutting machine of cord

Technical field

The utility model belongs to the cutting device of cotton tyre cord, is specifically related to the vertical cutting machine of a kind of cord.

Background technology

At present, machine driving is adopted in the severing of cord, drives one by motor, reductor and cranks arm, and driving rack, gear and ratchet mechanism are realized going forward one by one of cord.Fixed length to cord is to control by the length that adjusting is cranked arm, and fixed length is adjusted more complicated, and precision is lower.In to the cord fixed length, utilize tooth bar and speed increaser drive sprocket chain, drive cut-off knife and move back and forth the severing cord.Adopt this structure, cord is unidirectional severing, and production efficiency is lower, and the speed increaser fault is frequent, and rack-and-pinion is easy to wear, and the running noise is big.

Summary of the invention

The purpose of this utility model provides a kind of cord fixed length and the severing adjustment is simple, fixed length precision the is high vertical cutting machine of cord.

Technical solution of the present utility model is: the vertical cutting machine of cord by frame, control cabinet, pass cloth rewinder roll and cutting device is formed, pass cloth rewinder roll and be arranged on frame top, by driven by servomotor, above passing cloth rewinder roll, coaxial mounted length-testing wheel and encoder are set; Cutting device is installed in frame one side, by knife rest, rotary rail, pass the cloth pushing block and clamp mechanism is formed, Rodless cylinder is housed on the knife rest, cut-off knife drives by Rodless cylinder, can in the knife rest spacing hole, move up and down pass the cloth pushing block be arranged on cut-off knife above, rotary rail and frame are fixed, and the knife rest that cut-off knife is housed can rotate on rotary rail; The slide block of clamp mechanism is contained between pressing plate and the knife rest, and by sliding before and after the air cylinder driven slide block, slip front is processed with the cutter groove; Servomotor controller and programmable controller PLC are housed in the control cabinet, and servomotor controller is connected with servomotor, and the touch-screen that is loaded on the frame is connected with programmable controller PLC with encoder.

During work, big cord is rolled into the open position of leading of frame, under the drive of leading out axle, cord is imported into passs cloth rewinder roll, under driven by servomotor, drives cord and enters the cut-off knife device.In importing process, length-testing wheel is advanced and is rotated with cord, with the coaxial encoder of length-testing wheel with length signals input programmable logic controller PLC, after length reaches setting value, send instruction by PLC, stop to pass cloth by servomotor controller control servomotor.

Grip slide travels forward under the drive of cylinder, clamps cord, will pass the cloth pushing block simultaneously and lift, and cut-off knife is the severing cord under the drive of Rodless cylinder.

The utility model compared with prior art, its effect and advantage are:

1, original machine driving changes the direct transmission of servomotor into, increases the cord measuring motion on drive roll, detects cord length, utilizes the good positioning performance of servomotor, realizes the fixed length target.It is simple in structure, precise control, and fixed length and severing precision height, equipment failure rate is low.

2, original chain drive and the unidirectional severing of cut-off knife partial cancellation used well behaved Rodless cylinder instead and driven cut-off knife, back and forth severing, and operating efficiency significantly improves.

Description of drawings

Fig. 1 is the vertical cutting machine structural representation of cord;

Fig. 2 is the cutting device structural representation;

Fig. 3 is the side view of Fig. 1.

Wherein: 1, servomotor 2, pass cloth rewinder roll 3, encoder 4, length-testing wheel 5, rotary rail 6, touch-screen 7, cutting device 8, frame 9, knife rest 10, pass cloth pushing block 11, pressing plate 12, slide block 13, cutter groove 14, Rodless cylinder 15, cut-off knife 16, lead out axle 17, big cord volume 18, control cabinet

The specific embodiment

As Fig. 1, shown in Figure 3, frame 8 is the staged setting, and big cord volume 17 is arranged on the frame bottom, leads out axle 16 and is positioned at big cord and rolls up 17 1 sides, passs cloth rewinder roll 2 and is arranged on frame top, is driven by servomotor 1.Above passing cloth rewinder roll 2, encoder 3 and length-testing wheel 4 are set, the coaxial installation of encoder and length-testing wheel.

Cutting device 7 is contained in frame 8 one sides, by knife rest 9, rotary rail 5, pass cloth pushing block 10 and clamp mechanism is formed.Knife rest rotary rail 5 is fixing with frame 8, and knife rest 9 is arranged on the rotary rail 5, adjusts the severing angle of cord by rotary rail 5.Cut-off knife 15 is connected with the motion block of Rodless cylinder 14, and drives by Rodless cylinder 14, and limit switch is equipped with at the Rodless cylinder two ends, and limit switch is connected with programmable controller PLC, with the stroke of control cut-off knife.The connecting pin of passing cloth pushing block 10 is arranged in the knife rest spacing hole of cut-off knife top, and under the effect of clamp mechanism, passing cloth pushing block 10 can move up and down in the knife rest spacing hole.The slide block 12 of clamp mechanism is contained between pressing plate 11 and the knife rest 9, and by sliding before and after the air cylinder driven slide block, slip front is processed with cutter groove 13.

Control cabinet 18 is contained on the mainframe 8, and servomotor controller and programmable controller PLC are housed in the control cabinet.Servomotor controller is connected with servomotor, and touch-screen is connected with programmable controller PLC with encoder.The model of the programmable controller PLC that the utility model adopts is FX2N-64MR.

In the process of cord severing, by being installed on the touch-screen 6 input severing length on the frame 8, determine the severing angle with the relative position of rotary rail 5 by adjusting knife rest 9 by the operative employee.Air cylinder driven slide block 12 by clamp mechanism moves ahead, and will pass cloth pushing block 10 and lift, and cord is clamped between cut-off knife and the slide block, and the suitable slide block cutter groove of cut-off knife is with the cord severing.
