Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting equipment, and particularly relates to a die-cutting and peeling mechanism. Background Technique

[0002] Die-cutting is a cutting process for the post-processing of printed products, mainly used to cut printed products or other paper products into the required shapes or cut marks according to pre-designed graphics. This process makes the shape of the printed products no longer limited to straight edges and right angles, providing more design possibilities for products. With the rapid development of the electronics industry, die-cutting is not only limited to the post-processing of printed products, but also widely used in the production of auxiliary materials for industrial electronic products. Die-cutting materials are rich and diverse, including rubber, tape, foam, plastic, etc., and are widely used in multiple industries such as electroacoustics, healthcare, display signs, and electronic power. The die-cutting and peeling mechanism separates the products after die-cutting processing from the waste materials, ensuring the efficiency and accuracy of the die-cutting process, reducing the rejection rate, and improving the production efficiency.

[0003] A Chinese patent with the publication number of CN212608429U discloses a die-cutting and peeling mechanism, which includes a bracket, a first support column, a cross roller, and a slide rail. The bracket is fixedly connected with a first support column, the upper and lower parts of the first support column are connected with a first pinch roller, an air pump is arranged in the middle of the first support column, the air pump is connected with a second pinch roller through a telescopic rod, a cross roller is arranged at the top of the first support column, a slide rail is arranged inside the cross roller, and a blade is connected in the slide rail through a second bolt.

[0004] Although the above solution solves the problem that the existing cylindrical film has no corresponding peeling mechanism and cannot be peeled off, which increases the cost of enterprises, the movement of the blade in this peeling mechanism is relatively cumbersome, and it is necessary to rotate the second bolt to move. Moreover, the movement paths of the two blades are not convenient to control, and the synchronism of the movement cannot be guaranteed. At the same time, the disassembly and assembly of the placement roller also require rotating the first bolt, resulting in inconvenient disassembly and assembly processes. Therefore, it does not meet the existing requirements, and for this reason, we propose a die-cutting and peeling mechanism. Content of the Utility Model

Then release the pulling block 7, and the slide block 4 is reset under the action of the reset spring 6 to fix the placing roller 8. Rotate the handwheel 16, drive the double-threaded transmission rod 11 to rotate through the rotating rod 15. Further, the two moving blocks 13 make opposite or opposite horizontal movements under the constraint of the guide rod 12, driving the blades 14 to move synchronously, realizing the precise cutting of the film. The cut film is wound by the two winding rollers 18. Start the motor 20, drive the two winding rollers 18 to rotate synchronously through the transmission belt 19, and complete the winding work of the film.

When the moving blocks 13 move, they will drive the blades 14 to move synchronously, so that the moving distances of the two blades 14 can be ensured to be equal. At the same time, the operation of adjusting the movement of the blades 14 is simple and convenient, and easy to operate. The two winding rollers 18 can wind the cut film. At this time, start the motor 20, the motor 20 will drive one of the winding rollers 18 to rotate through the coupling. At this time, under the drive of the transmission belt 19, the other winding roller 18 can be driven to rotate synchronously, so that the synchronous rotation of the two winding rollers 18 can be realized, without using two or more motors 20, reducing the production cost. At the same time, the structure is simplified, and the maintenance becomes more convenient and simple, further reducing the maintenance cost.
