Description

Technical Field

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

[0002] Release paper, also known as silicone oil paper, anti-sticking paper or separator paper, is an engineering technology product widely used in materials engineering. Its main function is to isolate sticky objects, such as tapes, to prevent them from sticking together and to protect the isolated materials from contamination. Release paper lamination is a special release paper treatment process, mainly referring to the process of coating a layer of plastic film (such as polyethylene PE) on the paper surface.

[0003] In the process of release paper production, a laminating machine is needed. The Chinese utility model patent with the publication number CN220099527U discloses a laminating machine for evenly coating release paper in release paper production, including a conveyor belt platform, a release paper body arranged above the conveyor belt platform, and a laminating mechanism arranged above the conveyor belt platform. It also includes a flattening component, which is used to flatten both sides of the release paper body. The flattening component is arranged on the conveyor belt platform. The flattening component includes multiple groups of first brackets, and multiple groups of the first brackets are arranged on both side walls at the upper end of the conveyor belt platform. A group of bearings are arranged on the inner side walls of multiple groups of the first brackets, and a group of guide rollers are connected to the other ends of multiple groups of the bearings. By setting the flattening component, the utility model can flatten and guide both sides of the release paper body, avoiding the problem that both sides of the release paper body are bent, which may cause the laminating mechanism to be unable to evenly laminate the release paper body, and improving the efficiency and quality of laminating the release paper body.

[0004] However, during the use of this utility model, it can only flatten the paper before lamination. After lamination, the surface of the paper may be unevenly laminated, and it is impossible to flatten the paper after lamination, resulting in a poor final forming effect of the release paper and unable to meet the production requirements. Therefore, a release paper laminating machine is proposed to solve the problems raised above. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a release paper laminating machine, which has the advantage of being convenient for uniform treatment after lamination, and solves the problem that it can only flatten the paper before lamination, and after lamination, the surface of the paper may be unevenly laminated, and it is impossible to flatten the paper after lamination, resulting in a poor final forming effect of the release paper and unable to meet the production requirements.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A release paper laminating machine, comprising a workbench and a conveyor roller shaft rotatably connected inside the workbench and extending to its top. The upper surface of the conveyor roller shaft is provided with raw material paper. On the top of the workbench, there is a leveling structure for leveling the raw material paper after lamination, and on the top of the workbench, there is a stirring mechanism for stirring the hot-melt plastic.

[0007] The leveling structure includes a mounting frame fixedly connected to the top of the workbench. A threaded rod extending into its interior is threadedly connected to the top of the mounting frame. One end of the threaded rod close to the workbench is rotatably connected to a spreading brush, and the other end of the threaded rod away from the spreading brush is fixedly connected to a rotating handle.

[0008] The stirring mechanism includes a support frame fixedly connected to the top of the workbench. Inside the support frame, a raw material tank is fixedly installed. On the top of the raw material tank, a driving motor is fixedly installed. A stirring frame extending into the raw material tank is fixedly connected to the output shaft of the driving motor.

[0009] Further, a driving device for driving the conveyor roller shaft is fixedly installed inside the workbench, and the upper surface of the conveyor roller shaft is in contact with the raw material paper.

[0010] Further, on one side of the spreading brush close to the threaded rod, a limiting guide rod extending to the top of the mounting frame is fixedly connected, and the number of the limiting guide rods is two.

[0011] Further, a steel pipe is fixedly connected inside the support frame. A communicating pipe is fixedly connected between the steel pipe and the raw material tank. A spray head is fixedly connected to one side of the steel pipe close to the workbench.

[0012] Further, a valve is fixedly installed outside the communicating pipe, and a feed pipe extending into its interior is fixedly connected to the top of the raw material tank.

[0013] Further, on the front and back of one side of the workbench away from the mounting frame, support plates are fixedly connected, and a leveling roller is arranged between the two support plates.

[0014] Further, on the front and back of the leveling roller, positioning rods extending to the opposite sides of the two support plates are fixedly connected, and positioning grooves adapted to the positioning rods are formed inside the two support plates.

[0015] Further, a fixing frame is fixedly installed on one side of the workbench, and a winding drum is rotatably connected inside the fixing frame.

[0016] Compared with the prior art, the present utility model provides a release paper laminating machine, which has the following beneficial effects:

[0017] 1. The release paper laminating machine can drive the raw material paper to be conveyed by setting the conveying roller shaft. Then, by rotating the threaded rod, the leveling brush is driven to move downward, so that the leveling brush can contact the raw material paper. Thus, when the raw material paper is moving, the leveling brush can level the hot-melt plastic on the surface of the raw material paper, and then complete the leveling treatment after lamination, making the surface of the produced release paper more uniform and improving the forming effect.

[0018] 2. The release paper laminating machine can stir the hot-melt plastic inside the raw material tank by setting a driving motor to drive the stirring frame to rotate, avoiding the solidification phenomenon of the hot-melt plastic due to long-term stillness. It solves the problem that only the paper before lamination can be leveled, and after lamination, the lamination on the paper surface may be uneven, and the leveling treatment after lamination cannot be carried out, resulting in a poor final forming effect of the release paper and not meeting the production requirements.
