Description

Technical Field

[0001] The utility model relates to the technical field of film tearing wheels, in particular to a high-viscosity film tearing wheel that is easy to adjust. Background Art

[0002] It mainly involves the field of high-viscosity fluid film formation, especially the all-solid-state or gel electrolytes used in lithium and lithium-ion batteries. Compared with traditional organic liquid electrolytes, this type of electrolyte has better safety, higher energy density and better cycle life. Polyvinylidene fluoride (PVDF) is widely used in this type of electrolyte due to its advantages such as good thermal stability, good electrochemical stability and good film-forming properties. The casting solution formed by dissolving PVDF in N-methylpyrrolidone (NMP) is a high-viscosity fluid with a viscosity greater than 500 Pa·s. At present, the commonly used film-forming method is the solution casting method, which is simple to operate and low in cost, but the film thickness and uniformity are difficult to control. In order to overcome these shortcomings, researchers used electrospinning to prepare thin films. By regulating the voltage and receiving distance, different film thicknesses and nanofiber sizes can be obtained. It has high controllability, but there are problems of high cost and high equipment requirements;

[0003] Patent CN205220008U discloses a film-tearing roller for a backlight assembly machine, comprising a cylindrical roller body, the outer surface of which is covered with a PU adhesive layer, and is characterized in that the diameter of the roller body after being coated with the PU adhesive layer is 20-25 mm. By adopting the above structure, the diameter of the roller body after being coated with the PU adhesive layer is reduced to 20-25 mm, thereby reducing the contact area between the roller and the backlight film. Compared with the traditional roller with a diameter of 30 mm after being coated with the PU adhesive layer, the contact area between the roller and the backlight film is reduced, so that the film tearing process will not cause the backlight film to be torn off, thereby reducing the scrap rate of the backlight film. The diameter of the roller body after being coated with the PU adhesive layer is 21-24 mm; the adoption of this structure further ensures the adhesion between the roller and the film, ensuring that only the film is torn off and the backlight film is not torn off.

[0004] At present, the traditional high-viscosity film tearing wheel cannot be fixed according to the inner diameter of different film tearing cylinders when it is installed on the film tearing cylinder, so it is necessary to frequently replace the film tearing wheels of different diameters to increase the work intensity. At the same time, after the film tearing wheel is wound, it is not convenient to remove the film tearing cylinder with the film wound on it from the film tearing wheel, which reduces the efficiency of film winding.

[0024] The distance between the two shells 4 is adjusted to complete the fixation of the film tearing cylinder 5. Then, when in use, first insert the fixed buckle rod 2 at both ends of the wheel drum 1 and install the device on the film tearing machine. At this time, the film is fixed on the film tearing cylinder 5. At this time, the telescopic rod 32 is connected to the power supply. After the telescopic rod 32 is connected to the power supply, it can be extended and shortened. When the telescopic rod 32 is shortened, the movable plate 33 can push the rack 34. When the rack 34 is pushed, the gear 35 installed on the inner side of the mounting bracket 39 can be rotated to make the bidirectional screw rod 36 rotate. The rotation of the bidirectional screw rod 36 drives the threaded rectangular block 37 to rotate and move at the center of the bidirectional screw rod 36. Limit blocks are fixed on both sides of the bidirectional screw rod 36. The setting of the limit block plays the role of limiting the rectangular block 37, so that the rectangular block 37 can move at the center of the bidirectional screw rod 36, pushing the round rod 38 toward the center of the wheel drum 1, so that the two shells 4 are docked.

At this time, the outer wall of the shell 4 is in close contact with the inner wall of the film tearing cylinder 5, completing the fixation of the film tearing cylinder 5, thereby facilitating the fixation of film tearing cylinders 5 with different inner diameters, and there is no need for staff to frequently replace film tearing wheels of different diameters, thereby reducing the work intensity of the workers.

[0027] See also Figure 3 In order to quickly connect the two wheel drums 1, the connecting mechanism 6 includes a connecting block 61, one side of the connecting block 61 is fixedly connected to one end of the wheel drum 1, a groove 62 is provided on one side of the connecting block 61, and a mounting block 63 is provided on the top and bottom of one side of the connecting block 61.

The protrusion 65 is inserted into the inside of the groove 62, thereby enhancing the firmness of the connection. The protrusion 65 on the connecting block 2 64 is inserted into the inside of the groove 62 on the surface of the connecting block 1 61 for preliminary connection and fixation. At the same time, the mounting block 63 is inserted into the inside of the mounting groove 66, thereby enhancing the stability of the connection between the connecting block 1 61 and the connecting block 2 64. By setting the groove 62 and the protrusion 65, it can be ensured that the connection between the wheel drum 1 on one side of the connecting block 1 61 and the wheel drum 1 on the side of the connecting block 2 64 is more stable, avoiding loosening during the film tearing process, thereby ensuring the stable operation of the film tearing wheel.

When the rack 34 is pushed, the gear 35 installed on the inner side of the mounting bracket 39 can be rotated to rotate the bidirectional screw rod 36. The rotation of the bidirectional screw rod 36 drives the threaded rectangular block 37 to rotate and move at the center of the bidirectional screw rod 36, and limit blocks are fixed on both sides of the bidirectional screw rod 36. The limit blocks The setting plays the role of limiting rectangular block 37, so that the rectangular block 37 can move at the center of the bidirectional screw rod 36, pushing the round rod 38 toward the center of the wheel drum 1, so that the two shells 4 are docked, and then extend into the film tearing cylinder 5, and then control the telescopic rod 32 to extend the operation, the telescopic rod 32 drives the moving plate 33 and the rack 34 to operate, and the rack 34 drives the gear 35 to rotate in the opposite direction, and under the action of the bidirectional screw rod 36, drives the rectangular blocks 37 on both sides to move relatively away, so that the round rod 38 pushes the shell 4 out. At this time, the outer wall of the shell 4 is in close contact with the inner wall of the film tearing cylinder 5, completing the fixation of the film tearing cylinder 5, thereby facilitating the fixation of the film tearing cylinder 5 with different inner diameters, and does not require the staff to frequently replace the film tearing wheels of different diameters, thereby reducing the work intensity of the workers;

[0030] Then, a protrusion 65 is fixedly installed in the middle position of the surface of the connecting block 2 64 between the mounting grooves 66, and a groove 62 matching the protrusion 65 is opened on the surface of the connecting block 1 61. The protrusion 65 is inserted into the inside of the groove 62, thereby enhancing the firmness of the connection. The protrusion 65 on the connecting block 2 64 is inserted into the inside of the groove 62 on the surface of the connecting block 1 61 for preliminary connection and fixation. At the same time, the mounting block 63 is inserted into the inside of the mounting groove 66, thereby enhancing the stability of the connection between the connecting block 1 61 and the connecting block 2 64. By setting the groove 62 and the protrusion 65, it can be ensured that the connection between the wheel drum 1 on one side of the connecting block 1 61 and the wheel drum 1 on the side of the connecting block 2 64 is more stable, avoiding loosening during the film tearing process, thereby ensuring the stable operation of the film tearing wheel.
