Description

Technical Field

[0001] The utility model relates to the technical field of release paper die-cutting devices, in particular to a die-cutting device used for release paper production. Background Art

[0002] Release paper is a kind of paper with anti-sticking effect, which is usually used to isolate sticky substances. Release paper usually consists of a three-layer structure, including base paper, coating layer and silicone oil layer. Release paper is an important industrial material. It provides a convenient way to handle and manage sticky items through special treatment. The die-cutting device is a very important equipment in the production of release paper. It is used to accurately cut the release paper to meet different application requirements.

[0003] In the prior art, a patent with publication number CN106042063A discloses an efficient die-cutting device for release paper, which mainly drives the die-cutting knife cylinder to reciprocate up and down through a cylinder and transmits the die-cutting product through a transmission chain to improve the efficiency of die-cutting.

[0004] It is known from the technology in the related field that for the die-cutting devices for the production of release paper, most of the die-cutting devices contain certain gum in the paper when die-cutting. During the continuous die-cutting process, it is easy to adhere to the cutter or remain adhered to the paper after die-cutting, which affects the die-cutting effect, has poor self-cleaning effect, and has low efficiency when used. Utility Model Content

[0005] The purpose of the utility model is to provide a die-cutting device for release paper production in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A die-cutting device for release paper production, comprising a die-cutting housing, a cleaning unit and an air blowing unit;

[0008] Die-cutting shell: A lifting mechanism is installed at the upper end, and a long box is connected to the inside of the die-cutting shell for sliding up and down. The lifting end of the lifting mechanism is connected to the upper end of the long box, and a cutter is installed at the lower end of the long box. The release paper to be die-cut is placed on the platform inside the die-cutting shell. The lifting mechanism can move the cutter down quickly through the long box to die-cut the release paper.

[0009] The cleaning unit comprises a driving long shaft with one end rotatably connected to one side of the inner part of the long box, a reciprocating annular groove is provided on the driving long shaft, and the reciprocating annular groove is divided into a deep section and a shallow section, a guide column is slidably connected to the inner upper end of the long box, the lower end of the guide column is connected to the upper end of the connecting frame, a groove sliding column is installed at the inner upper end of the connecting frame, the lower end of the groove sliding column is fitted in the reciprocating annular groove, a cleaning plate is connected to the lower end of the connecting frame, and a brush is installed on the cleaning plate extending out of the lower end of the long box; The lower end of the groove slide column always slides in the reciprocating annular groove. When the active long shaft rotates, the groove slide column can make the connecting frame and the cleaning plate reciprocate left and right, and then the inclined brush at the lower end of the cleaning plate can be used to clean the blade of the cutter; because the reciprocating annular groove is divided into deep section and shallow section, and the lower end of the groove slide column is always close to the bottom of the reciprocating annular groove, the groove slide column can reciprocate in the vertical direction while reciprocating left and right, which is more conducive to cleaning the release paper waste adhering to the cutter from different angles.

[0010] Blowing unit: It includes a tilting plate seat installed at the rear side of the lower end of the long box, a tilting plate shaft is installed in the tilting plate seat, and an air-passing plate is movably connected to the tilting plate shaft, and an air-passing plate is provided with an air-jet hole inside. External positive pressure gas is ejected through the air-jet hole to blow the blade of the cutter and the brush, and the air-passing plate can be tilted at a certain angle to facilitate blowing the cutter and the brush from different angles.

[0011] Furthermore, the cleaning unit further comprises a motor installed on the other side of the long box, the output shaft of the motor is connected to the other end of the active long shaft, and the upper end of the connecting frame is connected to an elastic member. When die-cutting release paper, the motor works to rotate the active long shaft, providing a power basis for the cleaning cutter, the upper side of the elastic member contacts the upper side of the long box, and the guide column slides in the long slot at the upper end of the long box.

[0012] Furthermore, the blowing unit further comprises a common gas groove opened inside the gas passing plate, a pressed rod is provided at the upper end of the gas passing plate, a pressing plate is installed at the rear end of the cleaning plate, the rear end of the pressing plate is slidably connected to the pressed rod, and a gas pipe joint is installed at the rear end of the gas passing plate. After the external positive pressure gas enters the common gas groove through the gas pipe joint, it can be ejected through the air jet hole. When the groove slide column moves downward with the connecting frame and the cleaning plate, the pressing plate can press the pressed rod downward. Through the principle of lever, the front end of the gas passing plate rises, and then the gas ejected from the air jet hole changes its angle.

[0013] Furthermore, the deep section and the shallow section in the reciprocating annular groove are arranged alternately. The deep section and the shallow section in the reciprocating annular groove are arranged alternately and continuously, which ensures the stability of the left-right and up-and-down reciprocating motion of the cleaning plate with the brush.

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

[0015] 1. The utility model utilizes the cooperation between the groove slide column and the reciprocating ring groove to make the cleaning plate reciprocate left and right, and utilizes the brush to clean the blade of the cutter. At the same time, the waste release paper after die-cutting can be swept down to prevent the waste from blocking the die-cutting effect.

[0016] 2. In the utility model, since the reciprocating ring groove is divided into a deep section and a shallow section, the sliding column in the groove can reciprocate in the vertical direction while reciprocating left and right, which is more conducive to cleaning the release paper waste adhering to the cutter from different angles. At the same time, the gas is ejected through the air jet hole, and the angle is also changed, so the cutter and the brush are purged more comprehensively, and the cutter is self-cleaned during die-cutting, and the continuous die-cutting efficiency is higher and the effect is better.
