Description

Technical Field

[0001] This utility model relates to the field of film slitting technology, specifically to a film slitting machine with a dust removal device. Background Technology

[0002] A film slitting machine is a specialized piece of equipment used to cut wide-width film materials into multiple narrow-width strips. It is widely used in industries such as packaging, printing, electronics, and new energy (e.g., lithium battery separators). Its core function is to precisely cut large rolls of film into multiple smaller rolls of material of the required width.

[0003] Film slitting machines generally consist of an unwinding system, a traction system, a slitting system, a winding system, and a control system. After the film is slitted by the slitting system, the winding system is used to wind up the slitted film. However, the current winding system has a simple structure and lacks dust removal function, which causes dust carried on the film to be drawn in during the winding process. This dust adheres to the film surface and can cause defects (such as scratches and dents), affecting the product's appearance and performance. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a film slitting machine with a dust removal device, which avoids dust from approaching the film by means of the mounting shell and the feeding shell, and solves the problems mentioned in the background art by means of the suction function.

[0005] This utility model is achieved through the following technical solution: a film slitting machine with a dust removal device, comprising multiple take-up reels and mounting shells, wherein the mounting shells are evenly arranged among each other, and each mounting shell has a feed shell communicating with the mounting shell on its outer ring surface. Each mounting shell has a through hole at both ends, and each feed shell has an operation port communicating with the through hole on one side. A baffle is provided on the outside of the operation port. Each take-up reel is disposed in the mounting shell, and both sides of the take-up reel are thickened and disposed in the through hole. Each take-up reel has a first gear installed at both ends. Each adjacent mounting shell and the outer mounting shell has a second gear meshing with the first gear. The second gears are all meshed with and connected to the first gear. Each feed shell has a support frame installed at the end away from the mounting shell.

[0006] As a preferred technical solution, both sides of the winding reel are provided with a ring-shaped positioning groove, which is exposed. One end of each baffle is bent to form a positioning part, which is inserted into the positioning groove.

[0007] Each baffle is equipped with a fixed seat, each fixed seat has a positioning hole, each positioning hole has a positioning rod, one end of each positioning rod is bent and installed on the outer wall of the feed shell, and the other end is equipped with a limit block. Each positioning rod is equipped with a fixing ring, and each positioning rod is fitted with a compression spring. One end of each compression spring is installed on the fixed seat, and the other end is installed on the fixing ring.

[0008] As a preferred technical solution, the support frame includes a fixed rod, a fixed frame, and multiple connecting rods. The fixed rod is longitudinally arranged below the feed shell and is fixedly connected to the end face of the feed shell through multiple hinges. The fixed frame is arranged outside the mounting shell, and the connecting rods are installed between the fixed rod and the fixed frame.

[0009] As a preferred technical solution, the fixing frame is arranged in a "U" shape, with bearings embedded on both sides of the fixing frame, a shaft installed between the second gears, and both ends of the shaft installed in the inner ring of the bearings. A motor is installed on one side of the fixing frame, and the motor shaft is fixedly connected to one end of the shaft.

[0010] As a preferred technical solution, the second gear and the mounting housing are not in contact, and the distance between the second gear and the mounting housing is less than the distance required for the winding reel to move out of the through hole.

[0011] As a preferred technical solution, the inner diameter of the through hole matches the diameter of the upper plate of the winding reel.

[0012] As a preferred technical solution, a dust suction pipe connected to the feed housing is installed on the feed housing.

[0013] The beneficial effects of this utility model are: the structure of this utility model is simple, and the section of the take-up reel and the film near the take-up system are covered by the mounting shell and the feed shell, which prevents external dust from coming into contact with them. Combined with the air extraction structure, the dust inside the mounting shell and the feed shell can be removed, which greatly reduces the probability of dust adhering to the film and ensures the quality after take-up. At the same time, the take-up reel is easy to install and remove, which increases efficiency. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a film slitting machine with a dust removal device, comprising multiple take-up reels 3 and mounting shells 2. The mounting shells 2 are evenly arranged among each other. Each mounting shell 2 has a feed shell 1 that communicates with it on its outer ring surface. Each mounting shell 2 has a through hole 20 at both ends. Each feed shell 1 has an operation port 19 that communicates with the through hole 20 on one side. A baffle 9 is provided on the outside of the operation port 19. Each take-up reel 3 is disposed in the mounting shell 2. Both sides of the take-up reel 3 are thickened and disposed in the through hole 20. Each take-up reel 3 has a first gear 4 installed at both ends. Each adjacent mounting shell 2 and the outer mounting shell 2 has a second gear 5 that meshes with the first gear 4. The second gear 5 is meshed with the first gear 4. Each feed shell 1 has a support frame installed at the end away from the mounting shell 2.

[0024] In this embodiment, the side plates on both sides of the winding reel 3 are provided with a ring-shaped positioning groove 21, and the positioning groove 21 is exposed. One end of the baffle 9 is bent to form a positioning part 10, and the positioning part 10 is inserted into the positioning groove 21.

[0025] A fixing seat 12 is installed on the outer side of the baffle 9. The fixing seat 12 is provided with a positioning hole. A positioning rod 15 is provided in the positioning hole. One end of the positioning rod 15 is bent and installed on the outer wall of the feed shell 1. The other end is provided with a limit block 11. A fixing ring 14 is installed on the positioning rod 15. A compression spring 13 is sleeved on the positioning rod 15. One end of the compression spring 13 is installed on the fixing seat 12. The other end is installed on the fixing ring 14.

[0026] In this embodiment, the support frame includes a fixed rod, a fixed frame 6, and multiple connecting rods 17. The fixed rod is longitudinally arranged below the feed shell 1 and is fixedly connected to the end face of the feed shell 1 through multiple hinges. The fixed frame 6 is arranged outside the mounting shell 2, and the connecting rod is installed between the fixed rod and the fixed frame 6.

[0027] In this embodiment, the fixing frame 6 is arranged in a "U" shape. Bearings are embedded on both sides of the fixing frame 6. A shaft 8 is installed between the second gear 5. The two ends of the shaft 8 are installed in the inner ring of the bearing. A motor 7 is installed on one side of the fixing frame 6. The rotating shaft of the motor 7 is fixedly connected to one end of the shaft 8.

[0028] In this embodiment, the second gear 5 and the mounting shell 2 are not in contact, and the distance between the second gear 5 and the mounting shell 2 is less than the distance required for the take-up reel 3 to move out of the through hole 20. After the mounting shell is located between adjacent mounting shells, the second gear can block both sides of the take-up reel, preventing the take-up reel from falling directly out of the through hole.

[0029] In this embodiment, the inner diameter of the through hole 20 matches the diameter of the upper plate of the take-up reel 3 to ensure the stability of the take-up reel after it is inserted into the through hole and to avoid swaying.

[0030] In this embodiment, each feed housing 1 is equipped with a suction pipe 16 that communicates with the feed housing 1; wherein, the suction pipe is connected to a vacuum cleaner through a flexible hose, and the negative pressure generated by the vacuum cleaner allows air and dust inside the feed housing and the mounting housing to enter the vacuum cleaner through the suction pipe. The mounting housing has an air inlet on the side facing the fixed frame to allow air convection, and each air inlet is equipped with a filter screen to prevent the filter screen from entering, thereby increasing the dust removal effect.

[0031] In use, lift the feed shell and mounting shell upwards around the hinge, so that the mounting shell separates from the adjacent mounting shells. At this time, the baffle can be pulled outwards along the positioning rod. The movement of the baffle drives the positioning part, so that the operating port and the through hole are opened, allowing the take-up reel to be inserted into the mounting shell through the through hole. The film can enter the feed shell from the operating port and be wound on the take-up reel. After the operation is completed, release the baffle and push the baffle downwards by the rebound of the compression spring until the baffle returns to its original position and blocks the operating port. The positioning part can be inserted into the positioning groove of the take-up reel to position the take-up reel longitudinally. As the mounting shell returns to its original position, the first gear on both sides of the take-up reel can be placed on the second gear and mesh with the second gear.

[0032] After the motor is started, the motor drives the shaft to rotate, which in turn drives the second gear. The rotation of the second gear drives the first gear, which in turn drives the rotation of the take-up reel, thereby winding the slit film onto the take-up reel. After winding is completed, the take-up reel can be quickly disassembled by lifting it up.

[0033] The winding reel and the section of film closest to the winding system are covered by the mounting shell and the feed shell to prevent external dust from coming into contact with them. Combined with the air extraction structure, dust inside the mounting shell and the feed shell can be removed, greatly reducing the probability of dust adhering to the film and ensuring the quality after winding.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
