Description

Technical Field

[0001] The utility model relates to the technical field of laminating machine cutting, in particular to a cutting device of a laminating machine. Background Art

[0002] A laminating machine is a machine used to combine paper, board materials, and film by applying pressure to a rubber roller and a heated roller, creating a paper-plastic composite. It can be categorized into two types: instant laminating machines and pre-coating laminating machines. Currently, the cutting mechanism of laminating machines is typically fixed to the laminating machine, with a fixed cutting range. During cutting, the film cutting area must be moved directly under the cutting mechanism, which is time-consuming and labor-intensive, resulting in low efficiency. Therefore, a mobile cutting mechanism for laminating machines is needed to improve this problem.

[0003] An existing mobile cutting device of a laminating machine (Announcement No.: CN211390515U) has at least the following disadvantages: the device is equipped with an electric push rod, a slider, a slide groove, a bottom plate, a cutting groove, and a round rod. The round rod drives the pressure plate to move upward along the square groove. The film comes out of the discharge port of the laminating machine and falls into the cutting groove and moves outward along the cutting groove. The downward moving cutting blade enters the cutting groove to cut the film. By setting a ball bearing, the sliding friction between the slider and the slide groove is converted to rolling friction, which reduces the friction force when the slider moves and speeds up the movement of the cutting blade. However, the device lacks a device for flattening the laminating material, which easily causes an uneven cutting surface, and the overall structure has slightly more electronic components. The electronic components are prone to failure, which also increases the production and manufacturing cost of the machine. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cutting device for a laminating machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cutting device for a laminating machine comprises a mounting bracket, a conveyor belt is mounted on the mounting bracket, a group of first brackets are symmetrically provided at the rear end of the top surface of the conveyor belt, a laminating machine is fixedly installed between the first brackets, a group of second brackets are symmetrically provided in the middle of the top surface of the mounting bracket, a clamping assembly is installed between the second brackets, the clamping assembly comprises a rotating rod 1, one end of the rotating rod 1 passes through the second bracket and is coaxially connected to a driving gear, a group of third brackets are symmetrically provided at the front end of the top of the mounting bracket, a rotating hole is opened on the third bracket, a transmission gear is rotatably connected in the rotating hole, a transmission chain is jointly sleeved on the outer wall of the transmission gear and the driving gear, and a group of cutting assemblies is installed between the two third brackets.

[0007] As a further solution of the present invention, an end of the rotating rod away from the driving gear passes through the second bracket and is coaxially connected to the motor, and a pressure roller is coaxially fixedly installed on the outer wall of the rotating rod.

[0008] As a further solution of the present invention, a rotating shaft is integrally formed at the center of the end face of the transmission gear, a small gear is coaxially fixedly installed on the rotating shaft, and the third bracket is rotatably connected to a rotating rod 2 just above the cutting assembly.

[0009] As a further solution of the present invention, one end of the second rotating rod passes through the third bracket and is coaxially connected to the large gear, and the large gear is meshed with the small gear for transmission connection.

[0010] As a further solution of the present invention, a cam is fixedly installed in the middle of the second rotating rod, and the outer arc wall of the cam abuts against the top surface of the cutting assembly. When the cam rotates, it drives the cutting assembly to move up and down.

[0011] As a further solution of the present invention, the cutting assembly includes a mounting plate, a mounting groove is provided on the mounting plate, a cutting blade is inserted and installed in the mounting groove, and sliders are integrally formed at both ends of the mounting plate.

[0012] As a further solution of the present invention, the opposing surfaces of the two third brackets are integrally formed with a slide groove, and the two sliders are respectively slidably connected in the two slide grooves. Springs are installed on the bottom surfaces of the two sliders, and the ends of the two springs away from the sliders are respectively in contact with the bottom surfaces of the slide grooves, and the springs can reset the cutting assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This device flattens and presses the material through the pressing roller in the pressing assembly, and sends it to the cutting assembly by the conveyor belt. The motor drives the active gear to rotate through the rotating rod 1, and the active gear drives the transmission gear to rotate through the transmission chain. The transmission gear drives the large gear to rotate through the small gear coaxially connected with it, and the large gear drives the cam to rotate through the rotating rod 2 coaxially connected with it. During the rotation of the cam, the mounting plate drives the cutting blade to move downward, and the spring installed in the slide groove is compressed until the cutting blade cuts the material. The cam continues to rotate, and the spring releases the elastic force to lift the mounting plate upward, so that the mounting plate drives the cutting blade to reset. This cycle is repeated, and the cutting blade cuts the material into the same length. This device is equipped with a pressing assembly to flatten the coated material. At the same time, through the setting of chain transmission and reduction gear group, while ensuring the working performance of the device, the use of electronic components is greatly reduced. The device has stable and reliable performance, low cost and is easy to install and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS
