Description

Technical Field

[0001] This utility model relates to the field of film peeling technology, and in particular to an adhesive film peeling mechanism. Background Technology

[0002] With the continuous development of automated production technology, coating materials have been widely used in various industrial fields such as packaging, printing, and electronics. To ensure that the surface of the coated product remains clean and intact in subsequent processes, the protective film is usually automatically peeled off by a film-peeling mechanism before the material with the protective film on it enters the next process. As a key auxiliary device in the supporting production equipment, the structural design of the film-peeling mechanism directly affects the operating efficiency and material adaptability of the entire production line, thus placing higher demands on its functional diversity and ease of adjustment.

[0003] In existing technologies, common film-peeling devices typically employ a combination of a fixed limiting mechanism and a mechanical clamping structure to peel off the protective film. The limiting device generally consists of a set of limiting rollers with a fixed spacing, the spacing of which is preset manually or by screw adjustment, working in conjunction with the main peeling roller to peel the film. The winding end usually uses a flexible clamp or pressure plate structure to install and position the winding roller. The overall structure is simple and suitable for processing standard-sized film materials. Its operation largely relies on structural rigidity and the initially set limiting state to complete continuous operation.

[0004] However, traditional film-tearing devices have a limited range of structural adjustments. When materials of different thicknesses need to be used alternately, the original fixed spacing limiting structure cannot be quickly adjusted, resulting in poor compatibility between materials of different specifications. This necessitates frequent disassembly of structural components or even replacement of limiting components, thereby increasing setup time and labor costs, severely impacting production line efficiency and equipment versatility, and limiting the device's adaptability in diverse production scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adhesive film-tearing mechanism, which aims to improve the problem that the limiting distance of traditional film-tearing devices cannot be adjusted, resulting in a narrow range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adhesive peeling mechanism, including a base, a frame fixedly connected to the top of the base, a limit groove being formed inside the frame, and an adjustment component being provided inside the frame;

[0007] The adjustment assembly includes a first limiting plate, which is slidably connected inside the frame. A limiting component is provided on the outer wall of the first limiting plate. A limiting post is slidably connected inside the first limiting plate. A second limiting plate is fixedly connected to one end of the limiting post. A driving component is provided inside the second limiting plate. A limiting roller is rotatably connected inside the second limiting plate. A spring is sleeved on the outer wall of the limiting post. One end of the spring is fixedly connected to the bottom of the first limiting plate, and the other end of the spring is fixedly connected to the top of the second limiting plate. An electric push rod is fixedly connected inside the frame, and the output end of the electric push rod is fixedly connected to the bottom of the first limiting plate.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a limiting block, one side of which is fixedly connected to the outer wall of a limiting plate, and the limiting plate is slidably connected to the inside of a limiting groove through the limiting block.

[0010] As a further description of the above technical solution:

[0011] The driving component includes a motor, the outer wall of which is fixedly connected to the inside of the limiting plate, and the output end of the motor is connected to one end of the limiting roller.

[0012] As a further description of the above technical solution:

[0013] A bracket is fixedly connected to the top of the base, and a fixed column is rotatably connected inside the bracket.

[0014] As a further description of the above technical solution:

[0015] A second motor is fixedly connected to one side of the bracket, and the output end of the second motor is connected to one end of the fixed column.

[0016] As a further description of the above technical solution:

[0017] The fixed column is rotatably connected to a threaded rod, and a limit groove is formed inside the fixed column.

[0018] As a further description of the above technical solution:

[0019] The threaded rod is threadedly connected to an external conical column, which is slidably connected inside the limiting groove.

[0020] As a further description of the above technical solution:

[0021] A telescopic rod is fixedly connected to the outer wall of the fixed column. A clamping plate is fixedly connected to one end of the telescopic rod. An inner cone column is fixedly connected to the inner wall of the clamping plate. The inner wall of the inner cone column fits against the outer wall of the outer cone column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the output end of the electric push rod first extends to drive the first limiting plate to rise. The first limiting plate slides and is limited in the first limiting groove by the limiting block, and releases the pressure between the spring and the second limiting plate, thereby increasing the distance between the limiting roller and the base. This achieves the effect of adapting to materials of different thicknesses, solves the problem that the limiting distance of the traditional film tearing device cannot be adjusted, resulting in a narrow range of application, and improves the practicality of the film tearing mechanism.

[0024] 2. In this utility model, rotating the threaded rod drives the outer cone column to slide on the outer wall of the fixed column. The outer cone column is limited by the second limiting groove on the fixed column. Then, the outer wall of the outer cone column contacts the inner wall of the inner cone column, causing the clamping plate to open. The clamping plate and the fixed column are limited by the telescopic rod, which achieves the effect of facilitating the installation of the take-up roller. This solves the problem that it is inconvenient to install the take-up roller when the film-tearing mechanism is storing the film, and improves the convenience of the film-tearing mechanism.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 The present invention provides an embodiment of an adhesive film peeling mechanism, comprising a base 1, which serves as the supporting foundation for the overall mechanism and provides stable support for each structural component. A frame 2 is fixedly connected to the top of the base 1. The frame 2 is used to install and maintain the position of the limiting and adjustment related mechanism. A limiting groove 3 is opened inside the frame 2. The limiting groove 3 is used to guide the linear movement of the limiting plate 5 to ensure the stability and accuracy of the movement direction during the adjustment process. An adjustment component is provided inside the frame 2.

[0034] The adjustment assembly includes a first limiting plate 5, which serves as a movable adjusting component to adjust the limiting distance of the mechanism. The first limiting plate 5 is slidably connected inside the frame 2 and guided by a first limiting groove 3. A limiting component is provided on the outer wall of the first limiting plate 5 to precisely limit its sliding and prevent it from deviating from the preset track. A limiting post 7 is slidably connected inside the first limiting plate 5, connecting the upper and lower limiting structures and transmitting the adjustment action. One end of the limiting post 7 is fixedly connected to a second limiting plate 8. The limiting roller 10 and the drive mechanism are used to support the limiting roller 10. The upper and lower floating mechanism allows for adjustable limiting distances to accommodate materials of different thicknesses. A drive assembly is installed inside the limiting plate 8, providing power output to the limiting roller 10 to ensure the continuity and effectiveness of the film-tearing operation. The limiting roller 10 is rotatably connected inside the limiting plate 8. As a component that directly contacts the material to be peeled, the limiting roller 10 is used to introduce and separate the adhesive material. A spring 11 is sleeved on the outer wall of the limiting post 7, providing upward elastic support to the limiting plate 8, ensuring its position within the limiting range. After plate 5 resets, it springs back to its initial state, ensuring the mechanism's recovery accuracy. One end of spring 11 is fixedly connected to the bottom of limit plate 5, and the other end is fixedly connected to the top of limit plate 8. An electric push rod 4 is fixedly connected inside frame 2. The electric push rod 4 serves as the actuator for driving limit adjustment and can move limit plate 5 up and down according to control commands, thereby achieving automatic adjustment of the limit distance. The output end of the electric push rod 4 is fixedly connected to the bottom of limit plate 5, driving limit plate 5 to complete the lifting and lowering action. The limit assembly includes limit block 6. The limiting block 6 is fixedly connected to the outer wall of the limiting plate 5 on one side. It is used to cooperate with the limiting groove 3 during the sliding process of the limiting plate 5 to ensure the stability and guidance of its position adjustment. The limiting plate 5 is slidably connected to the inside of the limiting groove 3 through the limiting block 6. The driving component includes a motor 9. The motor 9 serves as the driving source for the limiting roller 10 and can realize the continuous rotation of the limiting roller 10. The outer wall of the motor 9 is fixedly connected to the inside of the limiting plate 8 to ensure its stability during operation. The output end of the motor 9 is connected to one end of the limiting roller 10 to realize the transmission of driving power.

[0035] Reference Figure 4 and Figure 5A bracket 12 is fixedly connected to the top of the base 1. The bracket 12 serves as the load-bearing structure for the upper mounting components, providing stable support for the fixed column 14 and other components such as the motor. The fixed column 14 is rotatably connected inside the bracket 12, providing a central shaft structure for rotational transmission, facilitating relative rotation of the threaded rod 15 within the bracket. A second motor 13 is fixedly connected to one side of the bracket 12, providing rotational power and serving as the main power source for driving the fixed column 14 and its internal mechanisms. The output end of the second motor 13 is connected to one end of the fixed column 14, facilitating the transmission of rotational power to the fixed column 14 and driving the internal structure to move in tandem. A threaded rod 15 is rotatably connected inside the fixed column 14. The threaded rod 15 rotates to drive the outer conical column 19 on it to move axially, achieving automatic adjustment of the clamping function. A second limiting groove 20 is provided inside the fixed column 14, guiding the outer conical column 19 to slide in a predetermined direction, preventing rotation or deviation, and improving the stability and accuracy of the adjustment mechanism. The threaded rod 15 is threadedly connected to an outer tapered column 19. The outer tapered column 19 serves as a control component for the movement of the clamping plate 17. Under the rotation of the threaded rod 15, it can move axially to adjust the clamping state. The outer tapered column 19 is slidably connected inside the limiting groove 20 to ensure it maintains the correct orientation during movement and prevents rotational errors. A telescopic rod 16 is fixedly connected to the outer wall of the fixed column 14. The telescopic rod 16 connects to and drives the movement of the clamping plate 17, adapting to the opening and closing requirements of the clamping plate 17 and providing auxiliary support. One end of the 16 is fixedly connected to a clamping plate 17. The clamping plate 17 is used to install on both sides of the coating material to limit or clamp the coating. An inner conical column 18 is fixedly connected to the inner wall of the clamping plate 17. The inner conical column 18 is used to cooperate with the outer conical column 19. The clamping plate 17 is opened or tightened through a wedge structure. The inner wall of the inner conical column 18 is in contact with the outer wall of the outer conical column 19 to form a conical pressing structure. During the axial movement of the outer conical column 19, the clamping plate 17 is driven to open and close, thereby completing the function of clamping or releasing the coating roll.

[0036] Working principle: When using this adhesive film peeling mechanism, when installing the take-up roller, the take-up roller is directly placed on the outer wall of the clamping plate 17. Then, the threaded rod 15 is rotated to drive the outer cone column 19 to slide on the outer wall of the fixed column 14. The outer cone column 19 is limited by the limiting groove 20 on the fixed column 14. Then, the outer wall of the outer cone column 19 contacts the inner wall of the inner cone column 18, which drives the clamping plate 17 to open. The clamping plate 17 and the fixed column 14 are limited by the telescopic rod 16, which achieves the effect of facilitating the installation of the take-up roller.

[0037] When it is necessary to adjust the distance between the limiting roller 10 and the base 1, the output end of the electric push rod 4 extends to drive the limiting plate 5 to rise. The limiting plate 5 slides and is limited in the limiting groove 3 through the limiting block 6, and releases the pressure between the spring 11 and the limiting plate 8, thereby increasing the distance between the limiting roller 10 and the base 1. At the same time, the limiting roller 10 is limited in the limiting plate 5 through the limiting plate 8 and the limiting post 7, so that the tension of the spring 11 can push the limiting roller 10 to fit against the top of the material. Then, the output end of the motor 9 drives the limiting roller 10 to rotate, which can assist in moving the material. Then, the film is wound on the top take-up roller for collection, achieving the effect of adapting to materials of different thicknesses.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
