Description

Technical Field

[0001] This utility model relates to the technical field of film production equipment, and in particular to a coating head with dual gap adjustment. Background Technology

[0002] When producing certain roll materials, especially films and stickers with a certain degree of adhesiveness, a release film is often included on one side. When the film or sticker is needed, it is peeled off the release film. Since it's rolled up, a section is taken off when needed. However, because it's produced as a whole roll, scissors are required to remove a section. Therefore, it's necessary to pre-cut the film during roll material production, creating a crease, so that users can easily remove the film without scissors. However, different roll materials have different thicknesses, so the distance between the cutting roller and the feeding roller needs to be adjustable.

[0003] The existing substrate feeding mechanism for release film processing includes a lower feeding mechanism and an upper feeding mechanism. The lower feeding mechanism has fixed plates installed on both the left and right sides. The top of the electric push rod is connected to a top plate. The upper feeding roller is located above the lower feeding mechanism. The top of the upper feeding roller is fixed with a threaded connecting column. The top of the top plate is equipped with a controller, and the edge of the top plate has a round hole.

[0004] Although the aforementioned equipment can adjust the distance between the feeding mechanisms on both sides, it cannot solve the aforementioned technical problems. It cannot cut the roll material to create slits, nor can it adjust the distance between the cutting roller and the feeding roller according to the thickness of the roll material. Utility Model Content

[0005] The purpose of this invention is to provide a coating head with dual gap adjustment to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The coating head with double-adjustable gap includes a pair of frames. Each of the opposite side walls of the pair of frames is rotatably equipped with a rotating plate. Each of the ends of the pair of rotating plates is slidably connected to a slider, and each slider is equipped with a pressure-cutting roller. Multiple feeding rollers are rotatably connected between the pair of frames. Each of the front ends of the pair of rotating plates is fixedly equipped with a sliding seat. The slider is slidably connected to the rotating plate through the sliding seat. The slider is threadedly connected to a handwheel that adjusts the position of the slider relative to the sliding seat. Both ends of the pressure-cutting roller are rotatably connected to the slider. A driving component is provided at the rear end of one of the rotating plates. The output end of the driving component is hinged to the rotating plate. The driving component controls the rotation of the rotating plate relative to the frames.

[0008] To elaborate further, the cutting roller is arranged adjacent to one of the feeding rollers, and the distance between the cutting roller and the feeding roller is adjustable.

[0009] To elaborate further, a screw is fixedly installed at the bottom of the handwheel, the screw passes through the sliding seat, and the screw is threadedly connected to the sliding seat and the slider.

[0010] To elaborate further, the pressure cutting roller has a cylindrical structure, and the side of the pressure cutting roller is provided with an inwardly recessed cutting groove, which forms a cutting edge with the side wall of the pressure cutting roller.

[0011] To elaborate further, the sliding seat includes a pair of guide posts, and the slider is provided with a pair of through holes. The slider is sleeved on the guide posts through the through holes and is slidably connected to the guide posts.

[0012] To elaborate further, a positioning mounting seat is fixedly installed on the opposite side wall of a pair of frame plates. A rubber plate is inserted into the positioning mounting seat, and a limit plate is fixedly installed on the rubber plate. The limit plate is provided with a fan-shaped groove corresponding to the shape of the outer side wall of the pressure cutting roller. The limit plate is used to limit the further deflection of the pressure cutting roller.

[0013] To elaborate further, the limiting plate is designed to not contact the pressure cutting roller.

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

[0015] This utility model is equipped with an electric push rod, a cutting roller and a handwheel. The cutting roller is controlled by a cylinder to move downward within a certain period of time to squeeze the roll material, so as to create a certain indentation on the roll material, making it easier for the user to remove the film from the roll material.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0024] like Figure 1-2 As shown, this embodiment provides a coating head with dual-adjustment gap, including a pair of frame plates 1. The frame plates 1 are mounted on the production equipment during use. Rotating plates are rotatably mounted on opposite side walls of the pair of frame plates 1. The rotating plates are used to mount the pressure-cutting roller (mentioned below). The rotating plates can initially control the pressure-cutting roller to undergo a large initial deflection, causing the pressure-cutting roller to move closer to or further away from the feeding roller 2. To further finely adjust the gap between the pressure-cutting roller and the feeding roller 2, an adjustment assembly is also installed between the rotating plates and the pressure-cutting roller.

[0025] The adjustment assembly includes a slider 13, a sliding seat 6, and a handwheel 9. A slider 13 is slidably connected to the end of each pair of rotating plates, and a cutting roller is mounted on each slider 13. Multiple feeding rollers 2 are rotatably connected between the pair of frame plates 1. A sliding seat 6 is fixedly mounted at the front end of each pair of rotating plates. The slider 13 is slidably connected to the rotating plate via the sliding seat 6. A handwheel 9 is threadedly connected to the slider 13 to adjust its position relative to the sliding seat 6. Both ends of the cutting roller are rotatably connected to the slider 13. A drive member 8 is located at the rear end of one of the rotating plates, and the output end of the drive member 8 is hinged to the rotating plate. The drive member 8 controls the rotation of the rotating plate relative to the frame plate 1. In this embodiment, a screw 10 is fixedly mounted at the bottom of the handwheel 9, passing through the sliding seat 6, and threadedly connected to the sliding seat 6 and the slider 13. Therefore, when it is necessary to finely and precisely adjust the distance between the cutting roller and the feeding roller 2, the user needs to manually turn the handwheel 9 to control the up and down movement of the slider 13 through the screw 10. The cutting roller is rotatably connected to the slider 13, so the final distance between the cutting roller and the feeding roller 2 can be controlled.

[0026] In this embodiment, the cutting roller and one of the feeding rollers 2 are arranged adjacent to each other, with a distance between them that is adjustable. The driving component 8 is preferably a cylinder, with the piston rod end of the cylinder rotatably connected to the rotating block. Initially, the cylinder's extension is fixed, so the final distance must be adjusted using an adjusting assembly. This is because the roll material does not require continuous control of the cutting roller during production; instead, the cylinder periodically controls the rotating block 7 to rotate. When the cylinder rises, it controls the cutting roller to approach the feeding roller 2 for cutting. The duration of cylinder retraction depends on the length of the indentation intervals on the film.

[0027] In this embodiment, the cutting roller has a cylindrical structure and an inwardly recessed groove is provided on the side of the cutting roller. The groove and the side wall of the cutting roller form a cutting edge 12. When the cutting edge 12 comes into contact with the film, it will leave an imprint on the film or sticker, so that the user can peel off the film along the imprint.

[0028] In this embodiment, the sliding seat 6 includes a pair of guide posts, and the slider 13 is provided with a pair of through holes. The slider 13 is sleeved on the guide posts through the through holes and is slidably connected to the guide posts.

[0029] In this embodiment, a positioning mounting base 5 is fixedly provided on the opposite sidewalls of a pair of frame plates 1. A rubber plate 4 is inserted into the positioning mounting base 5, and a limiting support plate 11 is fixedly provided on the rubber plate 4. The limiting support plate 11 is provided with a fan-shaped groove corresponding to the shape of the outer sidewall of the pressure cutting roller. The limiting support plate 11 is used to limit the further deflection of the pressure cutting roller. If the impression roller 3 overturns excessively, it will cut the roll material. The limiting support plate 11 can effectively prevent the impression roller 3 from overturning. Specifically, the impression roller 3 can rotate freely relative to the limiting support plate 11. When the impression roller 3 moves into position to perform pressure cutting, the limiting support plate 11 is not in contact with the pressure cutting roller. Only when the rotating plate overturns will the pressure cutting roller come into contact with the limiting support plate 11.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
