The waste material collection assembly 22 is provided with a winding part 221, the winding part 221 winds the waste material mother plate at a second speed, and the second speed is higher than the first speed, so that the waste material mother plate is separated from the polaroid; the waste collection assembly 22 collects the waste master plate, and the conveyor belt 11 conveys the polaroid continuously.

The winding part 221 is used for winding and collecting the waste mother board, and the winding speed of the winding part 221 is higher than that of the die-cut mother board conveyed by the conveyor belt 11, so that the waste mother board and the polaroid are collected after being rapidly separated, smooth die cutting of the polaroid mother board is guaranteed, and disorder of a production field is avoided.

Referring back to fig. 3, the waste collection rack 21 further includes a first gantry body 211 and a second gantry body 212. The first gantry body 211 and the second gantry body 212 are arranged on the surface of the die-cutting bearing table 1 and are respectively located on two opposite sides of the conveyor belt 11, and the first gantry body 211 and the second gantry body 212 are parallel.

Specifically, the die cutting machine is arranged at one end of the die cutting bearing table 1, and the waste collecting frame 21 is arranged at the other end of the die cutting bearing table 1. The cross cutting machine carries out the cross cutting to banded polaroid master mask for the polaroid master mask is cut out the polaroid of a plurality of cell-phone screen sizes, and original polaroid master mask just becomes approximate netted, but at this moment, is still on the polaroid master mask after being cut, then the master mask after the cross cutting is shifted to conveyer belt 11 on, and conveys towards waste collection frame 21 under the effect of conveyer belt 11. First gantry support body 211 and second gantry support body 212 are approximate rectangular frame structures, both have an upper beam and a lower beam, first gantry support body 211 and second gantry support body 212 are perpendicular to the surface of die-cutting bearing platform 1 and are respectively located on two opposite sides of die-cutting bearing platform 1, namely located on two opposite sides of conveyor belt 11, and a mother plate after die-cutting conveyed by conveyor belt 11 passes through between first gantry support body 211 and second gantry support body 212.

Both ends of the winding portion 221 are rotatably connected to the upper beams of the first gantry body 211 and the second gantry body 212, respectively. Specifically, a winding support block is arranged at one end of the upper cross beam of the first gantry body 211 and the second gantry body 212, which is far away from the die-cutting machine, the winding portion 221 is a winding roller, and two ends of the winding portion are respectively connected to the two winding support blocks in a rotating manner. One end of the winding part 221 passes through the winding support block and is connected to a motor through a shaft coupling, and the winding part 221 is driven to rotate by the motor. The winding portion 221 is located above the conveyor belt 11 and is parallel to the conveyor belt 11. The die-cut mother board is provided with a waste mother board and a polaroid, wherein the waste mother board starts to be wound under the driving of the rotation of the winding part 221, the second speed of the winding part 221 for winding the waste mother board is greater than the first speed of the conveyor belt 11 for conveying the die-cut mother board, at the moment, the net-shaped waste mother board slightly deforms, the polaroid which is subjected to die cutting is separated from the waste mother board, the transmission is continued on the conveyor belt 11, the polaroid is collected at the tail end of the conveyor belt 11, and the waste mother board is wound and collected by the winding part 221. The separation shape of the waste mother plate and the polaroid is similar to a splayed shape. In specific application, the second speed is only slightly greater than the first speed, and thus the speed difference between the two speeds is large, so that the deformation of the waste mother plate is large, and the subsequent winding action is not facilitated. For example, when the conveying speed of the conveyor belt 11 is 3 meters per minute, the winding speed of the winding portion 221 may be 3.1 meters per minute.

Referring again to FIG. 3, still further, the waste collection assembly 22 includes a further separating portion 222. The separating part 222 includes a first separating roller 2221 and a second separating roller 2222.

The waste mother plate is wound around the winding unit 221 at an interval of years after passing through the first separating roller 2221 and the second separating roller 2222. Through the arrangement of the first separating roller 2221 and the second separating roller 2222, the waste mother plate can be turned and coiled once, so that the waste mother plate and the polaroid can be separated conveniently, and the waste mother plate and the polaroid can be separated smoothly. In addition, with such an arrangement, the winding part 221 can be arranged at a position higher than the conveyor belt 11, so that a space for winding the waste master is reserved, and more master wastes can be conveniently wound at one time.

Preferably, the second separation roller 2222 is located on the side of the first separation roller 2221 away from the die cutting machine, and the surface of the second separation roller 2222 has a soft fur brush. It can be understood that the mother plate waste will tilt when passing through the space between the first separation roller 2221 and the second separation roller 2222, and at this time, the polarizer will be separated from the lower portion of the mother plate waste, but it is difficult to avoid that some polarizers are separated at a slow speed, and by arranging the soft brush on the surface of the second separation roller 2222, the separation of such polarizers can be facilitated, so that the separation of the mother plate waste and the polarizers can be smoothly and completely performed, and the soft brush will not damage the polarizers. Preferably, the separating portion 222 further includes a separating roller driving member (not shown). The output end of the separation roller driving part is connected to an end of the second separation roller 2222, which drives the second separation roller 2222 to rotate.

When the waste mother set passes through the space between the first separating roller 2221 and the second separating roller 2222 to change the direction, the first separating roller 2221 is required as a separating point, that is, the mother set waste needs to be wound around the first separating roller 2221, so that the angle at which the waste mother set is separated from the polarizer, that is, the opening degree of the separation of the waste mother set from the polarizer in the shape of the Chinese character 'ba', can be adjusted by adjusting the distance of one separating roller 2221 relative to the conveyor belt 11. Because, the size of cell-phone screen is various, and the size of the polaroid of being cross cutting is also various, through above-mentioned setting, can be convenient for adapt to the waste material separation of the master mask after the different cross cutting sizes.
