Description

Technical Field

[0001] This utility model relates to the field of circular knife machine technology, specifically a belt conveyor device for a circular knife machine. Background Technology

[0002] In the electronics industry, a large number of plastic die-cut parts are produced. Sheet plastic parts are made using rotary die-cutting machines. Traditionally, collection is done manually. This method is inconvenient, especially for products with adhesive residue, which tend to stick together, directly leading to product defects. Furthermore, collection efficiency is very low, requiring constant manual picking and peeling in front of the machine, necessitating a large workforce. To address this, a belt conveyor system for rotary die-cutting machines was invented. Existing belt conveyors transport products using upper and lower belts, which are always in close contact, making it unsuitable for transporting thicker plastic die-cut parts, as these parts tend to stick to the belts. Therefore, this paper proposes a new belt conveyor system for rotary die-cutting machines that eliminates the drawbacks of existing systems. Utility Model Content

[0003] The purpose of this utility model is to provide a belt conveyor device for a circular knife machine to solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

The circular knife cutting machine body is mounted on the side of the upper mounting plate. Conveying components are mounted on the sides of the upper and lower mounting plates away from the circular knife cutting machine body. A first fixing frame is mounted on the side of the lower mounting plate closest to the circular knife cutting machine body, and a second fixing frame is mounted on the other side. Separation adjustment components are mounted on the first and second fixing frames. A collection box is mounted on one side of the lower mounting plate, and a collection component is mounted in the collection box.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0007] In one alternative embodiment: the conveying assembly includes an upper pulley and a lower pulley, the upper pulley being disposed on the side of the upper mounting plate, and the lower pulley being disposed on the side of the lower mounting plate. The fixed shafts of the upper and lower pulleys pass through the upper and lower mounting plates respectively and are fixedly connected to the rotating shaft of the first motor. Tensioning pulleys are disposed below both sides of the upper pulley and above both sides of the lower pulley. An upper belt is disposed on the upper pulley, tensioning pulleys, and fixed plate on the upper mounting plate, and a lower belt is disposed on the lower pulley, tensioning pulleys, and fixed plate on the lower mounting plate.

[0008] In one alternative: the separation adjustment assembly includes a threaded rod, which is vertically disposed inside the first fixed frame. The upper end of the threaded rod passes through the outer wall of the first fixed frame and is fixedly connected to the rotating shaft of the second motor. A movable block is threaded on the threaded rod. A slide rod is vertically disposed inside the second fixed frame. A slider is slidably disposed on the slide rod. The movable block and the slider are fixedly disposed on the side of the upper mounting plate.

[0009] In one alternative embodiment: the collecting assembly includes a connecting shaft, the two ends of which are rotatably mounted on the inner wall of the collecting box; symmetrically arranged bearing plates are provided on the side of the connecting shaft; a counterweight is provided on the upper surface of the bearing plate away from the first fixed frame; a limit rod is provided inside the collecting box, the limit rod being located below the bearing plate with the counterweight; a through groove is provided on the side of the collecting box, and a drawer is slidably arranged in the through groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes the coordination of a conveying component, a separation and adjustment component, and a collection component. By activating a second motor, the rotating shaft of the second motor drives a threaded rod to rotate, causing the moving block to move up or down. This adjusts the distance between the upper and lower belts, preventing excessive pressure on the plastic die-cut parts. When the plastic die-cut parts fall into the collection box, they land on the upper surface of a support plate on one side. When the weight of the plastic die-cut parts on the support plate exceeds the weight of the counterweight, the connecting shaft drives the support plate to rotate, causing the plastic die-cut parts to fall into the drawer. This achieves the purpose of controlling the belt spacing and facilitating the removal of collected products without affecting the collection process. Attached Figure Description
