Description

Technical Field

[0001] This utility model relates to the field of release film production technology, and in particular to a release film conveying and positioning component. Background Technology

[0002] Release film conveying and positioning components are key parts used in industrial production for the precise conveying and positioning of release films. They are commonly found in automated production lines in industries such as electronics, optics, and packaging. Their core function is to ensure that the release film maintains a stable position and tension during the conveying process, avoiding displacement or wrinkles, thereby ensuring the accuracy and quality of subsequent processing (such as lamination, cutting, printing, etc.).

[0003] A search revealed that patent CN220298976U discloses a release film delivery and positioning component.

[0004] However, the above technical solution has the following problems: during the production process, the release film comes in various sizes, and when it is positioned by the component, it cannot fit well with the release film of different sizes, which may cause the release film to shift on the conveyor roller, causing difficulties for subsequent processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where release films come in various sizes during production, and the components used for positioning cannot properly match the different sizes of release films, which may cause the release film to shift on the conveyor rollers and create difficulties for subsequent processing. Therefore, this invention proposes a release film conveying and positioning component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A release film conveying and positioning assembly includes a base plate, with side plates fixedly connected to both sides of the top of the base plate. The top corners of the two side plates are set to be arc-shaped, and a controller is provided on one side of the side plate. A positioning mechanism for facilitating the conveying of the release film is provided on the top front side of the base plate, and a cleaning mechanism for cleaning the release film is provided on the top rear side of the base plate.

[0008] In one possible design, the positioning mechanism includes an electric telescopic rod, two positioning plates, a fixed plate, a fixed column, and two conveying rollers. The two ends of the two conveying rollers are respectively fixedly connected to the sides of the two side plates. Each of the two positioning plates has a circular hole through which it is slidably fitted onto the two conveying rollers. The bottom of each of the two positioning plates is slidably connected to the top of the same base plate. The fixed end of the electric telescopic rod is fixedly connected to one side of the side plate, and the telescopic end of the electric telescopic rod is fixedly connected to one side of the positioning plate. One side of the fixed plate is fixedly connected to one side of the other positioning plate. One end of the fixed column is threaded through the top of the fixed plate and tightly abuts the top of the base plate. The other end of the fixed column is fixedly connected to a rotating handle.

[0009] In one possible design, the cleaning mechanism includes two first connecting plates, two second connecting plates, a motor, a bidirectional lead screw, a slide rod, two movable plates, and two cleaning brushes. One side of each of the two first connecting plates and one side of each of the two second connecting plates are fixedly connected to the side of the two side plates adjacent to each other. The two ends of the bidirectional lead screw are rotatably connected to the side of the two first connecting plates adjacent to each other via bearings. The top of the motor is fixedly mounted on the first connecting plate by bolts. The output shaft of the motor rotatably passes through the first connecting plate and is fixedly connected to the same bidirectional lead screw. One side of each of the two movable plates is threaded onto the same bidirectional lead screw. The two ends of the slide rod are fixedly connected to the side of the two second connecting plates adjacent to each other. The other side of each of the two movable plates is slidably mounted on the two slide rods. The two cleaning brushes are respectively disposed on the side of the two movable plates adjacent to each other for cleaning the release film surface.

[0010] In one possible design, connecting blocks are fixedly connected to both sides of the two cleaning brushes on opposite sides, and bottom grooves adapted to the connecting blocks are opened on the sides of the two moving plates that are close to each other. Adaptive threaded holes are opened on the four connecting blocks and the four bottom grooves. Four disassembly pins are threadedly connected to the interior of the multiple threaded holes. One end of each of the four disassembly pins is threaded through the threaded hole and bottom groove on the moving plate and extends to the threaded hole on the connecting block and is threadedly connected to the threaded hole on the connecting block. A rotating handle is fixedly connected to the other end of each of the four disassembly pins.

[0011] In one possible design, the rear sides of the base plate are provided with inclined surfaces to facilitate the sliding of foreign objects off the release film surface, and the bottom sides of the base plate are provided with storage boxes for storing foreign objects via snap-fit.

[0012] In one possible design, mounting plates are fixedly connected to both sides of the bottom of the base plate to facilitate the installation of the components. Both mounting plates are L-shaped and have multiple mounting holes for easy installation.

[0013] In one possible design, the same partition is fixedly connected to the side of the two side plates that are close to each other. Both positioning plates have rectangular holes that are adapted to the partition and slide onto the partition through the rectangular holes. The partition is located above the electric telescopic rod.

[0014] In this application, during use, the release film is passed between the cleaning mechanism and the two drive rollers. After receiving the positioning command, the controller starts the electric telescopic rod. The telescopic end of the electric telescopic rod begins to extend and retract, causing the positioning plate fixedly connected to it to slide on the conveyor roller. Since one positioning plate is driven by the electric telescopic rod, and the other positioning plate is fixed in position by a fixed plate and a fixed column, the distance between the two positioning plates gradually changes as the electric telescopic rod extends and retracts. When the distance between the two positioning plates is adjusted to match the width of the release film, the operator rotates the rotating handle on the fixed column to make one end of the fixed column make tight contact with the top of the base plate, thereby fixing the position of the positioning plate. At this time, the release film forms a stable conveying channel between the two positioning plates, ensuring that no deviation occurs during the conveying process.

[0015] During the release film conveying process, a cleaning mechanism needs to be activated to keep its surface clean. The motor is started by the controller, and the top of the motor is fixed to the No. 1 connecting plate by bolts. Its output shaft rotates through the No. 1 connecting plate and is fixedly connected to the same bidirectional lead screw. When the motor starts, it drives the bidirectional lead screw to rotate. One side of each of the two moving plates is threaded onto the same bidirectional lead screw, and the other side is slidably fitted onto two slide rods. Because the bidirectional lead screw has bidirectional threads, when it rotates, the two moving plates will move inward simultaneously. Two cleaning brushes are respectively set on the side of the two moving plates that are close to each other to clean the surface of the release film being conveyed. The bristles of the cleaning brushes are made of soft and wear-resistant material to avoid scratching the surface of the release film. When foreign objects fall on both sides of the release film, they slide down the inclined surfaces on both sides of the back of the base plate into the storage box. The storage box is set on both sides of the bottom of the base plate by buckles to facilitate subsequent cleaning of foreign objects.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the positioning plate is moved by an electric telescopic rod, which can accurately adjust the positioning according to the release film of different widths, improving the versatility and applicability of the component. The cooperation between the fixing column and the fixing plate ensures that the positioning plate can be firmly fixed after being adjusted to the appropriate position, ensuring the stability of the release film during the conveying process. The bidirectional lead screw is driven by a motor to rotate, causing the two moving plates to drive the cleaning brush to clean the surface of the release film, which can remove dust, impurities and other foreign objects from the surface of the release film and keep its surface clean.

[0018] The cleaning brush is connected to the movable plate via a disassembly column, allowing for easy disassembly and replacement. At the same time, the storage box facilitates the cleaning and collection of foreign objects after cleaning. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 A positioning component includes a base plate 1, side plates 2, a positioning mechanism, a cleaning mechanism, etc. The base plate 1 serves as the supporting foundation for the entire component, and side plates 2 are fixedly connected to both sides of its top. The top corners of the two side plates 2 are set to be arc-shaped to avoid scratching personnel or release film during operation. A controller is also provided on one side of the side plate 2 to control the operation of the component.

[0027] The positioning mechanism includes an electric telescopic rod 9, two positioning plates 10, a fixed plate 13, a fixed column 22, and two conveyor rollers 12. The two ends of the two conveyor rollers 12 are fixedly connected to the sides of the two side plates 2, forming a basic channel for conveying the release film. The two positioning plates 10 have circular holes and slide onto the two conveyor rollers 12 through these holes. Simultaneously, the bottoms of the two positioning plates 10 are slidably connected to the top of the base plate 1, ensuring that the positioning plates 10 can slide smoothly on the conveyor rollers 12. The fixed end of the electric telescopic rod 9 is fixedly connected to one side of the side plate 2, and the telescopic end is fixedly connected to one side of the positioning plate 10. The telescopic movement of the electric telescopic rod 9 can move one side of the positioning plate 10 on the conveyor roller 12. One side of the fixed plate 13 is connected to the other side of the side plate 2. One side of the positioning plate 10 is fixedly connected, and one end of the fixing post 22 is threaded through the top of the fixing plate 13 and tightly attached to the top of the base plate 1. The other end of the fixing post 22 is fixedly connected to a rotating handle. By rotating the rotating handle, the tightness between the fixing post 22 and the base plate 1 can be adjusted, thereby fixing the position of the positioning plate 10. During the release film conveying process, according to the width of the release film, the controller controls the electric telescopic rod 9 to extend and retract, driving the positioning plate 10 on one side to move, so that the distance between the two positioning plates 10 is adapted to the width of the release film, thereby achieving the positioning of the release film. After the positioning is completed, the rotating handle on the fixing post 22 is rotated to make the fixing post 22 tightly attached to the base plate 1, fixing the position of the positioning plate 10 on the other side, ensuring the stability of the release film during the conveying process.

[0028] The cleaning mechanism includes two first connecting plates 5, two second connecting plates 6, a motor 17, a double-acting lead screw 14, a slide rod 19, two moving plates 7, and two cleaning brushes 15. One side of each of the two first connecting plates 5 and one side of each of the two second connecting plates 6 are fixedly connected to the side of each of the two side plates 2, providing support for the other components of the cleaning mechanism. The two ends of the double-acting lead screw 14 are rotatably connected to the side of each of the two first connecting plates 5 via bearings. The top of the motor 17 is fixedly mounted on the first connecting plate 5 with bolts, and its output shaft rotates through the first connecting plate 5 and is connected to the same... A bidirectional lead screw 14 is fixedly connected. When the motor 17 starts, it will drive the bidirectional lead screw 14 to rotate. One side of each of the two moving plates 7 is threaded onto the same bidirectional lead screw 14, and the other side is slidably mounted on two slide rods 19. Since the bidirectional lead screw 14 has bidirectional threads, when it rotates, the two moving plates 7 will move inward or outward at the same time. Two cleaning brushes 15 are respectively set on the side of the two moving plates 7 that are close to each other, and are used to clean the surface of the release film being conveyed. The bristles of the cleaning brushes 15 are made of soft and wear-resistant material to avoid scratching the surface of the release film.

[0029] This application can be used in the field of release film production, or in other fields applicable to this application.

The two positioning plates 10 are provided with rectangular holes that are adapted to the partition 11 and are slidably fitted onto the partition 11 through the rectangular holes. The partition 11 is located above the electric telescopic rod 9. The partition 11 can play an auxiliary positioning role to ensure the stability of the positioning plate 10 during the movement process, and at the same time prevent the release film from getting stuck in the electric telescopic rod 9 and other components during the conveying process.

[0033] Two cleaning brushes 15 are fixedly connected to connecting blocks 21 on their opposite sides. Two moving plates 7 are provided with bottom grooves 20 that are adapted to the connecting blocks 21 on their opposite sides. The four connecting blocks 21 and the four bottom grooves 20 are provided with matching threaded holes. The interior of the multiple threaded holes is threaded with four disassembly pins 8. One end of the four disassembly pins 8 is threaded through the threaded hole on the moving plate 7 and the bottom groove 20 and extends to the threaded hole on the connecting block 21 and is threadedly connected to the threaded hole on the connecting block 21. The other end of the four disassembly pins 8 is fixedly connected with a rotating handle. By rotating the rotating handle on the disassembly pin 8, the cleaning brushes 15 can be easily removed from the moving plate 7 for cleaning or replacement.

[0034] Both sides of the rear side of the base plate 1 are provided with inclined surfaces 16 to facilitate the sliding of foreign objects from the release film surface. Both sides of the bottom of the base plate 1 are provided with storage boxes 18 for storing foreign objects by means of snap fasteners. When the foreign objects cleaned by the cleaning brush 15 fall onto the base plate 1, they will slide down into the storage boxes 18 through the inclined surfaces 16 for easy subsequent cleaning.

[0035] The bottom two sides of the base plate 1 are fixedly connected with mounting plates 3 to facilitate the installation of the component. The two mounting plates 3 are both L-shaped and have multiple mounting holes 4 for easy installation. Through the mounting plates 3 and mounting holes 4, the component can be easily installed on conveying equipment or other equipment that requires the use of release film.

Those skilled in the art can make any selections according to their needs or convenience. The electric telescopic pole 9 and motor 17 are both connected to the controller through lines and powered by an external power source.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
