Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, specifically to a waste paper removal mechanism for the inner hole of cardboard. Background Technology

[0002] Existing paperboard internal hole waste paper removal mechanisms include a cylinder, a pressure plate, and multiple paper-pressing punches. The punches are fixed to the pressure plate, and the cylinder drives the pressure plate, which in turn drives the punches to push into the internal holes of the paperboard, thus removing the waste paper. Since the internal hole positions vary for different types of paperboard, pressure plates that can accommodate the corresponding punches need to be designed and manufactured, increasing production costs. Furthermore, the punches are fixed to the pressure plate using bolt assemblies, making disassembly and assembly cumbersome and inconvenient to use. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing cardboard inner hole waste paper removal mechanism, which is cumbersome to disassemble and assemble and inconvenient to use, so as to provide a cardboard inner hole waste paper removal mechanism that is quick and easy to disassemble and assemble.

[0004] Therefore, this utility model provides a waste paper removal mechanism for cardboard inner holes, including a pressure plate, a first bolt assembly, and a paper-pressing punch. The pressure plate has multiple rows of elongated holes. The first bolt assembly includes a first bolt and a first nut mounted on the pressure plate. The first bolt has a first bolt head, a first screw, and a connecting rod connected sequentially from top to bottom. After the first screw passes through the elongated holes, it is fixedly connected to the first nut. The first screw can move within the elongated holes. The connecting rod has a threaded hole. The paper-pressing punch is fixed to the connecting rod by a second bolt. The paper-pressing punch has at least one set of first holes and second holes arranged horizontally and communicating with each other. The head size of the second bolt is larger than the size of the second hole and smaller than the size of the first hole. After the second bolt passes through the second hole, it is connected to the threaded hole of the connecting rod.

[0005] The two adjacent rows of elongated holes are connected by a third hole, and the first screw can move within the third hole.

[0006] The two adjacent rows of elongated holes and the third hole form an I-shape.

[0007] The bottom of the pressure plate is provided with multiple clamping springs. When the clearing mechanism is in an idle state, the distance between the bottom of the clamping spring and the pressure plate is greater than the distance between the bottom of the paper pressing punch and the pressure plate.

[0008] The paper pressing punch has two sets of first holes and second holes arranged vertically.

[0009] The technical solution of this utility model has the following advantages:

[0010] 1. The waste paper removal mechanism for cardboard inner holes provided by this utility model has a pressure plate with multiple rows of elongated holes. The first screw passes through the elongated holes and is fixedly connected to the first nut. This allows the position of the first screw to be adjusted according to different cardboard inner holes, thereby adjusting the position of the paper-pressing punch. This eliminates the need to produce many pressure plates, saving costs. In addition, the paper-pressing punch has a first hole and a second hole that are horizontally arranged and interconnected. The head size of the second bolt is larger than the size of the second hole but smaller than the size of the first hole. After the second bolt passes through the second hole, it is connected to the threaded hole of the connecting rod. When the paper-pressing punch needs to be replaced, it is only necessary to loosen the second bolt (without completely removing the second bolt), and then move the paper-pressing punch so that the first hole is aligned with the head of the second bolt, after which the paper-pressing punch can be disassembled. This makes disassembly and assembly quicker and more convenient, and easier for people to use.

[0011] 2. The waste paper removal mechanism for cardboard inner holes provided by this utility model has a third hole connecting two adjacent rows of elongated holes, and the first screw can move in the third hole, which makes it easier to adjust the position of the paper pressing punch and has a wider range of applications.

[0012] 3. The waste paper removal mechanism for cardboard inner holes provided by this utility model has multiple clamping springs at the bottom of the pressure plate. When the removal mechanism is in an idle state, the distance between the bottom of the clamping spring and the pressure plate is greater than the distance between the bottom of the paper pressing punch and the pressure plate. In this way, before the paper pressing punch contacts the waste paper in the inner hole, the clamping spring can press the cardboard. When the paper pressing punch completes the waste paper removal and lifts up, the cardboard will not be lifted by the paper pressing punch because it is pressed by the clamping spring.
