Description

Technical Field

[0001] The present application relates to the technical field of film cutting, and in particular to a film cutting device. Background Art

[0002] As laminated products are favored by the sales market, the demand for laminated products has also increased dramatically. The substrate of the laminated product enters the laminating process through a conveyor for lamination. The finished plate after lamination completes the film cutting process at the joint position of the original substrate and then enters the next process.

[0003] Currently, most film cutting is done manually. The slow speed of manual cutting restricts product production, and the labor intensity of cutting is high. Moreover, manual cutting cannot see the board joints, resulting in problems such as miscutting, non-cutting or uneven cutting edges, which seriously restricts the qualification rate and production efficiency of the coated products. Utility Model Content

[0004] In order to facilitate film cutting of film-coated products, the present application provides a film cutting device.

[0005] The present application provides a film cutting device, which adopts the following technical solution:

[0006] A film cutting device comprises a working plate, a fixed plate is arranged at the bottom of the working plate, a connecting plate is arranged on the fixing plate, the connecting plate is rotatably connected to the fixing plate through a pin shaft, a film cutting knife is arranged on one side of the connecting plate, a receiving groove for accommodating the film cutting knife is opened at the bottom of the working plate, a blade edge connected to the receiving groove is opened in the middle position of the working plate, the tip of the film cutting knife extends out from the blade edge, and an elastic member connected to the working plate is arranged at one end of the connecting plate away from the film cutting knife.

[0007] By adopting the above technical solution, the coated product is moved along the length direction of the working plate, and the tip of the film cutting knife extends from the blade to cut the film on the surface of the coated product. During the cutting process, the product in the film applies downward pressure to the film cutting knife, and the connecting plate rotates around the pin shaft as the axis. The elastic part provides the cutting knife with force close to the side of the working plate, so that the film cutting knife cuts the film, thereby improving the stability of the film cutting work.

[0008] Optionally, the elastic member includes a connecting rod and an elastic spring. A connecting groove for inserting the connecting rod is opened at the bottom of the working plate. One end of the connecting rod is fixedly connected to the connecting plate, and the other end extends into the connecting groove. The elastic spring is sleeved on the outside of the connecting rod.

[0009] By adopting the above technical solution, the connecting rod provides a limiting guide for the movement of the connecting plate, and the elastic spring connects the connecting plate to the working plate. When the cutting knife moves downward due to the pressure of the coated product, one end of the connecting plate connected to the connecting rod moves upward, and the elastic spring is compressed to push the connecting plate close to the side of the connecting rod downward, thereby applying an upward force to the cutting knife.

[0010] Optionally, an adjusting bolt is passed through the connecting plate, the adjusting bolt is threadedly connected to the connecting plate, and an end of the adjusting bolt abuts against the bottom of the working plate.

[0011] By adopting the above technical solution, the length of the adjusting bolt between the connecting plate and the working plate is controlled by rotating the adjusting bolt, and the size of the cutting knife exposed at the cutting edge is controlled.

[0012] Optionally, an abutment block is provided at the end of the adjusting bolt.

[0013] By adopting the above technical solution, the abutment block prevents the adjusting bolt from directly contacting the working plate, thereby reducing the wear on the end of the adjusting bolt.

[0015] By adopting the above technical solution, the film-coated product moving on the working plate is guided by the guide plate, and the film cutting operation can be performed by moving the film-coated product along the guide plate, which is simple and convenient to operate.

[0016] Optionally, a long groove is provided at the bottom of the guide plate close to one side of the working plate along the length direction of the guide plate.

[0017] By adopting the above technical solution, the film itself has elasticity, and the film will open to both sides after being cut, and the long groove provides space for the opened film.

[0018] Optionally, a rounded corner is provided at the top of the working board near the side of the working board.

[0019] By adopting the above technical solution, the laminated product can be conveniently moved along the length direction of the workbench through the rounded corners.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] The coated product is moved along the length direction of the working plate, and the tip of the film cutting knife extends from the blade edge to cut the film on the surface of the coated product. During the cutting process, the product in the film exerts downward pressure on the film cutting knife, and the connecting plate rotates with the pin as the axis. The elastic member provides the cutting knife with a force close to the side of the working plate, so that the film cutting knife cuts the film, thereby improving the stability of the film cutting work;

[0022] The connecting rod provides a limit guide for the movement of the connecting plate, and the elastic spring connects the connecting plate to the working plate. When the cutting knife moves downward under the pressure of the coated product, one end of the connecting plate connected to the connecting rod moves upward, and the elastic spring is compressed to push the connecting plate close to the connecting rod to move downward, thereby applying an upward force to the cutting knife.

[0023] By rotating the adjusting bolt, the length of the adjusting bolt between the connecting plate and the working plate is controlled, and the size of the cutting knife exposed at the cutting edge position is controlled. BRIEF DESCRIPTION OF THE DRAWINGS
