Description

Technical Field

[0001] This utility model relates to the field of folding device technology, and in particular to a plastic film folding mechanism that prevents sticking. Background Technology

[0002] After the membrane is produced, it is usually folded and stored using a folding mechanism for easy storage and transportation. This folding mechanism is a mechanical system used for the efficient folding and unfolding of flexible thin film materials. It is widely used in aerospace, medical, construction and other fields. Its core objective is to achieve compact folding of the film within a limited space.

[0003] Due to the inherent characteristics of the membrane, some membranes are relatively smooth. After being folded by a folding mechanism, they may stick together due to van der Waals forces, electrostatic adsorption, or material properties. When the membrane is subsequently unfolded, it may tear, resulting in unfolding failure and rendering the membrane unusable.

[0004] Therefore, how to provide a plastic film folding mechanism that prevents sticking is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an anti-adhesion plastic film folding mechanism. This invention solves the problem in the prior art where the film may stick together after folding due to van der Waals forces, electrostatic adsorption, or material properties, resulting in the film failing to unfold and becoming unusable.

[0006] According to an embodiment of the present invention, an anti-adhesion plastic film folding mechanism includes a film body and a guide frame. A guide block is fixedly connected to one side of the inner wall of the guide frame. The bottom end of the film body passes through the gap between the guide frame and the guide block from the top of the guide frame and reaches the bottom of the guide frame. Powder is movably placed at the top of the guide block inside the guide frame. The powder is movably attached to the surface of the film body. A mounting frame is provided at the bottom of the guide frame. A pressure roller group and a winding roller are rotatably connected to the inner side of the mounting frame. The winding roller is located below the pressure roller group.

[0007] The top of the guide frame is hinged to a top cover, and a handle is fixedly installed on the top of the top cover.

[0008] The two sides of the guide block form a "V" shape, and the included angle of the "V" shape at the top of the guide block is larger than the included angle of the "V" shape at the bottom of the guide block. The shape and size of the inner wall of the guide frame match the shape and size of the guide block.

[0009] The powder is corn starch.

[0010] The pressure roller assembly includes two sets of pressure roller bodies, which are rotatably connected to the inner wall of the mounting frame. The film body passes between the two sets of pressure roller bodies and then wraps around the surface of the take-up roller.

[0011] The side of the guide frame is provided with a collection component to prevent powder from scattering.

[0012] The collection assembly includes a collection frame, a collection fan, a guide pipe, an inlet, and a collection plate. The collection frame is fixedly installed on the surface of the guide frame. The collection fan is fixedly connected to the side of the collection frame near the top. A filter screen is embedded in the connection between the collection fan and the collection frame. The collection plate is fixedly installed at the bottom of the guide frame by bolts. The inlet is located on the side of the collection plate near the membrane body. One end of the guide pipe is fixedly connected to and communicates with the collection plate, and the other end of the guide pipe is fixedly connected to and communicates with the side of the collection frame near the top.

[0013] The collection assembly also includes a collection drawer, which is built into the side of the collection frame near the bottom. A sealing strip is provided in the gap between the collection drawer and the collection frame. Magnets are provided on the side of the collection drawer near the guide frame and on the surface of the guide frame.

[0014] The beneficial effects of this utility model are:

[0015] By setting a guide frame and a guide block, the membrane body is guided to undergo initial folding. At the same time, the powder on the top of the guide block comes into contact with the surface of the membrane body, adhering a layer of powder to the surface of the membrane body. This prevents the membrane body from sticking together when folded, thus achieving the effect of preventing the membrane body from sticking together when folded. This solves the problem in the prior art that the membrane may stick together after folding due to van der Waals forces, electrostatic adsorption, or material properties, resulting in the membrane failing to unfold and becoming unusable.

[0016] By setting up a collection component, excess powder is sucked in and collected, preventing powder from the membrane surface from flying into the air and affecting the surrounding environment. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-6 In this embodiment, the membrane body 1 and the guide frame 2 are included. A guide block 3 is fixedly connected to one side of the inner wall of the guide frame 2. The bottom end of the membrane body 1 passes through the gap between the guide frame 2 and the guide block 3 from the top of the guide frame 2 and reaches the bottom of the guide frame 2. The two sides of the guide block 3 form a "V" shape. The included angle of the "V" shape at the top of the guide block is larger than the included angle of the "V" shape at the bottom of the guide block. The shape and size of the inner wall of the guide frame 2 match the shape and size of the guide block 3.

[0027] In practice, the top and bottom "V" shaped angles of the guide frame 2 and the guide inner block 3 are smoothly transitioned by a flat slope to avoid the transition being too uneven and affecting the effect of the powder 4 adhering to the film.

[0028] The top of the guide block 3 is located inside the guide frame 2 and contains a movable powder 4, which is corn starch. The powder 4 is movably attached to the surface of the film body 1. The bottom of the guide frame 2 is provided with a mounting frame 5. The inner side of the mounting frame 5 is rotatably connected to a pressure roller group 6 and a take-up roller 7. The take-up roller 7 is located below the pressure roller group 6. The pressure roller group 6 includes two sets of pressure roller bodies. The two sets of pressure roller bodies are rotatably connected to the inner wall of the mounting frame 5. After passing between the two sets of pressure roller bodies, the film body 1 is wound around the surface of the take-up roller 7.

[0029] In practice, the membrane body 1 is first passed through the gap between the guide frame 2 and the guide inner block 3. This gap is designed according to the thickness of the membrane so that only the membrane and a thin layer of powder 4 can pass through. This prevents excess powder 4 from adhering to the surface of the membrane body 1. After passing through the guide inner block 3, the membrane body 1 reaches the pressure roller group 6. The membrane is squeezed by the two sets of pressure rollers in the pressure roller group 6 to fold it in half. After the membrane is folded, it enters the winding roller 7. The winding roller 7 is equipped with a drive unit (not shown in the figure) to control the winding roller 7 to wind up the membrane. After the membrane is wound up, the membrane body 1 is folded in half and the powder 4 forms an intermediate layer, thereby preventing the membrane body 1 from sticking together.

[0030] refer to Figure 1-6 In this embodiment, the top of the guide frame 2 is rotatably connected to a top cover 8 via a hinge, and a handle is fixedly installed on the top of the top cover 8. The shape of the top cover 8 matches the shape of the top of the guide frame 2.

[0031] In practice, the hinge is set on the side of the guide frame 2, and then the top cover 8 is placed on the top of the guide frame 2 for limiting, so that the top cover 8 is stably placed on the top of the guide frame 2, thereby achieving the purpose of protecting the powder 4.

[0032] refer to Figure 1-6 In this embodiment, the side of the guide frame 2 is provided with a collection component 9 to prevent the powder 4 from scattering. The collection component 9 includes a collection frame 10, a collection fan 11, a guide pipe 12, an inlet 13, and a collection plate 14. The collection frame 10 is fixedly installed on the surface of the guide frame 2. The collection fan 11 is fixedly connected to the side of the collection frame 10 near the top. A filter screen 15 is embedded in the connection between the collection fan 11 and the collection frame 10. The collection plate 14 is fixedly installed at the bottom of the guide frame 2 by bolts. The inlet 13 is located on the side of the collection plate 14 near the membrane body 1. One end of the guide pipe 12 is fixedly connected to and communicates with the collection plate 14. The other end of the guide pipe 12 is fixedly connected to and communicates with the side of the collection frame 10 near the top.

[0033] In practice, the collecting fan 11 is first started. The collecting fan 11 draws the air in the collection frame 10 to the outside of the collection frame 10. After the collecting fan 11 is started, it will draw air from the suction port 13. The suction port 13 draws in the powder 4 scattered in the air on the surface of the membrane body 1 and draws the powder 4 through the suction port 13, the collection plate 14 and the guide pipe 12 to the collection frame 10. Then the powder 4 in the air is filtered by the filter screen 15 and remains in the collection frame 10. The filtered air is discharged by the collecting fan 11, thus achieving the purpose of collecting the powder 4 scattered in the air. The collected powder 4 can be recycled.

[0034] refer to Figure 1-6 In this embodiment, the collecting component 9 also includes a collecting drawer 16, which is built into the side of the collecting frame 10 near the bottom. A sealing strip 17 is provided in the gap between the collecting drawer 16 and the collecting frame. Magnets 18 are provided on the side of the collecting drawer 16 near the guide frame 2 and on the surface of the guide frame 2.

[0035] In practice, to better transfer the collected powder 4, a collection drawer 16 is designed. Excess powder 4 in the collection frame 10 falls into the collection drawer 16 by its own gravity. When it needs to be transferred, simply move the collection drawer 16 to separate it from the collection frame 10, and then transfer the powder 4 in the collection drawer 16 to the top of the guide block 3. The sealing strip 17 is used to improve the sealing performance between the collection frame 10 and the collection drawer 16, while the magnet 18 stabilizes the collection drawer 16 through magnetic attraction and prevents the collection drawer 16 from sliding.

[0036] The working principle of this utility model is as follows:

[0037] First, the membrane body 1 moves downward under the action of the winding roller 7. The membrane body 1 comes into contact with the powder 4 after passing the guide frame 2 and the guide inner block 3. The powder 4 will adhere to the surface of the membrane body 1, forming a thin layer of powder 4 on the surface of the membrane body 1. Then, after passing under the guide inner block 3 and the guide frame 2, it is initially folded. The initially folded membrane body 1 is then finally folded by the pressure roller group 6, achieving the effect of folding the membrane body 1. The powder 4 layer is an intermediate layer between the folded membranes, thus preventing the folded membrane body 1 from sticking together. The powder 4 scattered in the air is collected, recycled and reused by the collection component 9, while avoiding the powder 4 from affecting the surrounding environment.

[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.
