Description

Technical Field

[0001] This utility model relates to the field of cleanroom equipment technology, and more specifically to a cleanroom equipment for the production of PVC antistatic film. Background Technology

[0002] PVC antistatic film is a type of adhesive-free film that relies on electrostatic adsorption to adhere to objects and provide protection. It is generally used on surfaces sensitive to adhesive residue, such as glass, lenses, high-gloss plastic surfaces, and acrylic surfaces. This film has a high electrostatic resistance value, effectively preventing the generation and accumulation of static electricity, reducing damage to the protected items, such as preventing damage to electronic components due to electrostatic discharge. Furthermore, as a self-adhesive film, it adheres to the surface of objects through electrostatic adsorption, with moderate adhesion, ensuring a firm bond without leaving adhesive residue or damaging the surface when removed.

[0003] Achieving a cleanroom environment is crucial in the production of PVC antistatic film, as it helps ensure product quality and performance. Generally, this requires production workshops to reach a high cleanliness level, such as Class 10,000 or higher. During the transportation of PVC antistatic film, a cleanroom pass-through window is installed in the cleanroom for cleaning. For example, there is a cleanroom pass-through window with prior art publication number CN222162403U.

[0004] However, currently, when workers transport PVC antistatic film to the cleanroom for production, dust and impurities on the surface of the PVC antistatic film enter the cleanroom along with it, contaminating the production environment and affecting the production efficiency of the PVC antistatic film. Therefore, this invention provides a cleanroom device for PVC antistatic film production that integrates transportation and filtration functions. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a cleanroom device for the production of PVC antistatic film. The device uses a conveyor belt to transport the PVC antistatic film, thereby improving transportation efficiency. Simultaneously, a gas filtration assembly is used to circulate and filter the gas within the protective cover and the transport platform, preventing dust and impurities from contaminating the cleanroom. Furthermore, the filtered gas blows the gas within the protective cover forward, further improving the filtration efficiency of dust and impurities, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust-free device for producing PVC antistatic film, comprising a conveyor table, a conveyor belt fixedly installed inside the conveyor table, a connecting component for fixing the PVC antistatic film fixedly installed on the outer wall surface of the conveyor belt, a protective cover fixedly installed on the top of the conveyor table, sealing doors penetrating the top front and rear sides of the protective cover, slots opened on the top front and rear sides of the conveyor table, the sealing doors being inserted into the slots, and sealing strips being provided between the sealing doors, slots, and protective cover to improve the sealing performance between the sealing doors, slots, and protective cover; a gas filtration assembly fixedly installed on the top of the protective cover, the gas filtration assembly comprising a filter shell installed on the top of the protective cover, and a filter element installed inside the filter shell.

[0007] In a preferred embodiment, a cover plate is detachably connected to the top of the inner cavity of the filter housing, and a mesh plate is detachably connected to the bottom of the inner cavity of the filter housing. The cover plate and the mesh plate are respectively located above and below the filter element. The mesh plate can support the filter element to be placed in the filter frame for use, and the cover plate can play a sealing role above the filter element, so that the filtered gas can be transmitted from the gas tube.

[0008] In a preferred embodiment, an air pipe is fixedly inserted through the top of the cover plate. The air pipe is connected to the inside of the filter shell, and one end of the air pipe is connected to an air pump. The air pump is fixed to the top of the cover. The air pump can improve the filtration efficiency of the gas inside the cover and the transport platform.

[0009] In a preferred embodiment, an air outlet pipe is fixedly provided on the rear side of the inner wall of the top of the protective cover. One end of the air outlet pipe passes through the protective cover and is connected to the air pump. The filtered gas is then transported back to the protective cover and the transport platform through the air outlet pipe, thereby balancing the internal air pressure of the two and preventing excessive air pressure from affecting the safety of use.

[0010] In a preferred embodiment, electric push rods are fixedly provided on both sides of the bottom of the two sealing doors. The top of the cover has the same number of mounting slots as the electric push rods. The electric push rods are fixed in the mounting slots. The sealing doors are driven to rise and fall by the electric push rods, thereby realizing the automatic opening and closing of the sealing doors and improving the feeding efficiency.

[0011] In a preferred embodiment, the connecting assembly includes a connecting plate fixed to the surface of the conveyor belt. Two spring pins for fixing PVC antistatic film are fixedly inserted through the top of the connecting plate. The spring pins are used to connect with the pallet containing the PVC antistatic film, thereby driving the pallet to move automatically into the protective cover, thereby improving transportation efficiency.

[0012] In a preferred embodiment, two symmetrically distributed limiting plates are fixedly provided on both the front and rear sides of the top of the transport platform. The limiting plates are located outside the sealed door, which facilitates the staff to quickly push the PVC antistatic film tray onto the conveyor belt.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a conveyor belt to transport PVC antistatic film, thereby improving transportation efficiency. At the same time, a gas filtration assembly is used to circulate and filter the gas in the protective cover and the conveyor table, thereby preventing dust and impurities from contaminating the cleanroom. In addition, the filtered gas blows the gas in the protective cover forward, which can, to a certain extent, blow dust and impurities into the filter frame for filtration.

[0015] 2. The sealing door is automatically raised and lowered by an electric push rod, which can improve the feeding efficiency. Sealing strips are installed between the sealing door and the slot and the cover. The sealing strips can fill the gaps, thereby improving the sealing performance and preventing leakage.

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.

[0025] Refer to the attached diagram in the instruction manual. Figures 1-5 This utility model provides a dust-free device for the production of PVC antistatic film, including a conveyor table 1. A conveyor belt 2 is fixed inside the conveyor table 1 by bolts. A connecting component 3 for fixing PVC antistatic film is fixed on the outer wall surface of the conveyor belt 2. The connecting component 3 includes a connecting plate 31 fixed on the surface of the conveyor belt 2. Two spring pins 32 for fixing PVC antistatic film are fixed through the top of the connecting plate 31. The spring pins 32 are inserted into the tray holes containing PVC antistatic film, thereby driving the tray to move automatically into the protective cover 4, thereby improving the transportation efficiency.

[0026] The top of the transport platform 1 is fixed with a protective cover 4 by several bolts. The protective cover 4 has sealing doors 5 extending through its front and rear sides. Electric push rods 10 are fixed to the bottom sides of the two sealing doors 5. The top of the protective cover 4 has the same number of mounting slots 11 as the electric push rods 10. The electric push rods 10 are fixed in the mounting slots 11 by bolts. The electric push rods 10 drive the sealing doors 5 to rise and fall, thereby realizing the automatic opening and closing of the sealing doors 5. The top of the transport platform 1 has slots 6 on its front and rear sides. The sealing doors 5 are inserted into the slots 6. Sealing strips 7 are provided between the sealing doors 5, the slots 6 and the protective cover 4 to improve the sealing performance between the sealing doors 5, the slots 6 and the protective cover 4.

[0027] The top of the protective cover 4 is fixedly provided with a gas filter assembly 8. The gas filter assembly 8 includes a filter shell 81 installed on the top of the protective cover 4. The filter shell 81 contains a filter element 82. The top of the inner cavity of the filter shell 81 is detachably connected to a cover plate 83 by bolts. The bottom of the inner cavity of the filter shell 81 is detachably connected to a mesh plate 84 by bolts. The cover plate 83 and the mesh plate 84 are respectively located above and below the filter element 82. The filter element 82 can be replaced by removing the cover plate 83.

[0028] An air pipe 85 is fixedly inserted through the top of the cover plate 83. The air pipe 85 is connected to the inside of the filter shell 81. One end of the air pipe 85 is connected to an air pump 86. The air pump 86 is fixed to the top of the protective cover 4. An air outlet pipe 9 is fixedly provided on the rear side of the inner wall of the top of the protective cover 4. One end of the air outlet pipe 9 passes through the protective cover 4 and is connected to the air pump 86.

[0029] In actual use, first open the sealing door 5 at the front of the protective cover 4. Then, the staff places the tray containing the PVC antistatic film on the transport table 1 and connects the connecting component 3 to the tray. The conveyor belt 2 is then used to move the tray into the protective cover 4. The conveyor belt 2 is driven by a motor and drive rollers to rotate. Since this is already well-known technology, it will not be elaborated further. After the sealing door 5 is closed, the air pump 86 is used to draw the gas from the protective cover 4 and the transport table 1. The gas and dust impurities are filtered by the mesh plate 84 and the filter element 82 and then transported from the air pipe 85, the air pump 86 and the conveying pipe to multiple air outlet pipes 9. The gas sprayed from the air outlet pipes 9 blows the gas in the protective cover 4 towards the front of the protective cover 4, which can blow the dust impurities in the protective cover 4 and the transport table 1 forward, thereby improving the filtration efficiency to a certain extent. After filtration is completed, open the sealing door 5 near the rear of the protective cover 4 to remove the tray, thus preventing dust impurities from contaminating the cleanroom along with the PVC antistatic film.

[0030] Refer to the attached diagram in the instruction manual. Figures 1-2 Two symmetrically distributed limiting plates 12 are fixed on the front and rear sides of the top of the transport platform 1. The limiting plates 12 are located outside the sealing door 5. The distance between the two limiting plates 12 is the same as the width of the pallet covered with PVC antistatic film. Therefore, when placing the pallet, the staff can use the two limiting plates 12 to accurately push the pallet onto the conveyor belt 2, thereby improving the transport efficiency.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
