Abstract
Description
Technical Field
[0001] This utility model belongs to the field of film coating technology, and in particular relates to a film coating flatness adjustment device. Background Technology
[0002] A film is a thin, flexible, transparent sheet. It is made of plastics, adhesives, rubber, or other materials. Films are widely used in the electronics, machinery, printing, and other industries.
[0003] When winding the film, the pressure of the existing pressure rollers on the film cannot be changed at any time. As the roll diameter gradually increases, the winding pressure of the film also increases, which can lead to stretching deformation and affect the flatness of the film. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:
[0005] A film overcoating flatness adjustment device includes a support frame. From left to right, a forming roller 1, a forming roller 2, and a take-up roller are sequentially installed on the support frame. A rubber pressure roller is arranged above the take-up roller. A connecting rod is rotatably connected to one end of the rubber pressure roller. A guide sleeve is fixedly connected to the end of the connecting rod away from the rubber pressure roller. A guide rod is movably fitted on the inner ring of the guide sleeve. The guide rod is fixed on the support frame, and a reflector is fixedly connected to the outer side of the guide sleeve. An infrared ranging module is arranged below the reflector and fixed on the side wall of the support frame. The forming roller 2 is equipped with a lifting mechanism electrically connected to the infrared ranging module.
[0006] As a preferred embodiment of the above technical solution, both ends of the forming roller one are fixedly connected to bearing seat one, and the bearing seat one is fixedly connected to the support frame; both ends of the forming roller two are fixedly connected to bearing seat two, and the bearing seat two is disposed above the support frame; both ends of the winding roller are fixedly connected to bearing seat three, and the bearing seat three is fixedly connected to the support frame.
[0007] As a preferred embodiment of the above technical solution, the lifting mechanism includes a fixed rod, one end of which movably passes through the inner ring of the bearing seat two and is fixedly connected to the support frame, and the other end is fixedly connected to a fixed plate. A cylinder is fixedly sleeved on the inner ring of the fixed plate, and the output end of the cylinder is fixedly connected to the bearing seat two.
[0008] As a preferred embodiment of the above technical solution, the support frame is fixedly equipped with a PLC module, which is electrically connected to the infrared ranging module and the cylinder respectively.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. The forming roller one and forming roller two of this utility model are used for shaping the film during the winding process. The initial pressure of forming roller one and forming roller two on the film is set to 0.3-0.5MPa. As the winding roller continuously winds the film, the roll diameter will continuously increase. The guide sleeve will be lifted upwards on the support frame through the rubber pressure roller and connecting rod, thereby changing the height of the reflector. When the infrared ranging module detects the change in the height of the reflector, the forming roller two is moved through the lifting mechanism to gradually reduce the pressure as the roll diameter increases, so as to prevent the film from being stretched and deformed due to excessive pressure.

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0016] Example
[0017] like Figure 1 and Figure 2 As shown, a film coating flatness adjustment device includes a support frame 10. From left to right, the support frame 10 is equipped with a forming roller 11, a forming roller 22, and a take-up roller 13. A rubber pressure roller 20 is arranged above the take-up roller 13. A connecting rod 21 is rotatably connected to one end of the rubber pressure roller 20. A guide sleeve 22 is fixedly connected to the end of the connecting rod 21 away from the rubber pressure roller 20. A guide rod 23 is movably sleeved on the inner ring of the guide sleeve 22. The guide rod 23 is fixed on the support frame 10, and a reflector 24 is fixedly connected to the outer side of the guide sleeve 22. An infrared ranging module 25 is fixed to the side wall of the support frame 10 below the reflector 24. A lifting mechanism 30 electrically connected to the infrared ranging module 25 is installed on the forming roller 22.
[0018] It should be noted that the guide slide 23 is non-cylindrical to prevent the rubber pressure roller 20 and the connecting rod 21 from rotating around the guide slide 23. The infrared ranging module 25 is of the type VL53L0X, but is not limited to it. The take-up roller 13 is wound up by a drive device, which is of the type but is not limited to a motor. The motor is mounted on the support frame 10, and the output end of the motor is fixedly connected to the take-up roller 13.
[0019] Specifically, forming roller 11 and forming roller 2 12 are used to shape the film during the winding process. The initial pressure of forming roller 11 and forming roller 2 12 on the film is set to 0.3-0.5MPa. As the winding roller 13 continuously winds the film, the roll diameter will continuously increase. The guide sleeve 22 will be lifted upwards of the support frame 10 by the rubber pressure roller 20 and the connecting rod 21, thereby changing the height of the reflector 24. When the infrared ranging module 25 detects that the height of the reflector 24 has changed, the lifting mechanism 30 controls the forming roller 2 12 to move, gradually reducing the pressure as the roll diameter increases, to prevent excessive pressure from causing the film to stretch and deform.
[0020] like Figure 1 As shown, both ends of the forming roller 11 are fixedly connected to bearing housing 14, which is fixedly connected to the support frame 10. Both ends of the forming roller 12 are fixedly connected to bearing housing 15, which is located above the support frame 10. Both ends of the winding roller 13 are fixedly connected to bearing housing 16, which is fixedly connected to the support frame 10.
[0021] Specifically, the forming roller 11 is restricted by the bearing seat 14, so that it can only rotate on its own axis and cannot move on the support frame 10. The forming roller 12 can be lifted and moved by the lifting mechanism 30. The winding roller 13 is restricted by the bearing seat 16, so that it can only rotate on its own axis and cannot move on the support frame 10.
[0022] like Figure 1 As shown, the lifting mechanism 30 includes a fixed rod 31. One end of the fixed rod 31 movably passes through the inner ring of the bearing seat 15 and is fixedly connected to the support frame 10. The other end is fixedly connected to a fixed plate 32. A cylinder 33 is fixedly sleeved on the inner ring of the fixed plate 32. The output end of the cylinder 33 is fixedly connected to the bearing seat 15.
[0023] Specifically, the inner ring of a bearing housing 15 is provided with two fixing rods 31, which enable it to move stably up and down via a cylinder 33.
[0024] like Figure 1 and Figure 2 As shown, a PLC module is fixedly installed on the support frame 10. The PLC module is electrically connected to the infrared ranging module 25 and the cylinder 33 respectively.
[0025] It should be noted that the PLC module model used is, but not limited to, Siemens S7-1200. The infrared ranging module 25 detects the distance. The PLC module presets a threshold. When the infrared ranging module 25 detects a change in distance, it sends a signal to control the cylinder 33 to start and stop through the PLC module.
[0026] Working principle: First, the PLC module is preset with a threshold value. The initial pressure of the forming roller 11 and forming roller 212 on the film is set to 0.3-0.5MPa. As the take-up roller 13 continuously winds up the film, the roll diameter will continuously increase. The rubber pressure roller 20 and the connecting rod 21 will lift the guide sleeve 22 upwards on the support frame 10, thereby changing the height of the reflector 24. When the infrared ranging module 25 detects the change in the height of the reflector 24, it sends a signal to control the cylinder 33 to start and stop through the PLC module. The lifting mechanism 30 controls the movement of the forming roller 212, gradually reducing the pressure as the roll diameter increases to prevent excessive pressure from causing the film to stretch and deform.
[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
