Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-6 This utility model provides a center curling slitting machine, including a slitting machine body 1. The slitting machine body 1 includes: a frame 3, a feeding end 2, a welding module 4, a cutting module 5, a support module 6, and a subsequent slitting module. The slitting module is existing technology and includes a cutter, a motor, etc. Its structure and principle can be learned by those skilled in the art through technical manuals, and will not be described in detail here. The cutting module 5 includes two slide blocks 402 that slide on the top of the frame 3. Guide seats 501 are fixed to the same side of the two slide blocks 402 by bolts. A guide rod 502 is slidably connected to one side of the guide seat 501. A mounting seat 503 is slidably connected to the top of the guide rod 502. A cutting scissors 504 is fixed to one side of the mounting seat 503 by bolts. The support module 6 includes a fixed frame 601 fixed on the inner walls of both sides of the frame 3, and a support plate frame 603 is slidably connected to the top of the fixed frame 601; When it is necessary to weld new and old roll film, stop the operation of the equipment. At this time, the tail end of the old roll film is located on the support frame 603. By adjusting the height of the cutter 504, the cutter 504 is brought into contact with the tail end of the old roll film. The mounting base 503 is pulled to move on the guide rod 502, so that the old roll film is cut with the cooperation of the support frame 603. After cutting, overlap the front end of the new roll film with the tail end of the old roll film, then start the welding module 4 to weld the two together. After welding, start the equipment again so that the welded roll film can continue to undergo the subsequent slitting process. The motor drives the cutter in the slitting module to rotate and slit the film roll according to the preset specifications, dividing the wide film roll into multiple narrow film rolls to meet different production needs. Throughout the process, the precise coordination between the cutting module 5 and the support module 6 ensures that the position of the old roll film tail is relatively fixed each time it is cut. This makes the welding point position of the new roll film and the old roll film accurate, eliminating the need to repeatedly adjust the position of the old roll film. This improves the efficiency of roll film feeding, reduces production delays and defect rates caused by changes in the welding point position, and enhances the overall production quality and efficiency.

[0025] In this utility model, the welding module 4 includes two second electric push rods 403 respectively fixed on opposite sides of two slide blocks 402. The movable end of the second electric push rod 403 is fixed to a mounting bracket 404 by bolts. A heating plate 405 is provided at the bottom of the mounting bracket 404. A first electric push rod 401 fixed to the frame body 3 is fixed to one side of the two slide blocks 402 by bolts. When it is necessary to weld new and old roll film, the first electric push rod 401 is activated, which pushes the two slide blocks 402 to slide relative to each other on the top of the frame 3, so that the two heating plates 405 move to both sides of the tail end of the old roll film. At this time, the second electric push rod 403 is activated, which pushes the mounting frame 404 downward until the heating plate 405 is in close contact with the overlapping part of the new and old roll film. The heating plate 405 is powered on and heated to weld the overlapping part. After the welding is completed, the second electric push rod 403 drives the mounting bracket 404 to move upward, so that the heating plate 405 is detached from the film roll. The first electric push rod 401 drives the slide block 402 back to the initial position, preparing for the next welding operation. This welding method is easy to operate, has a good welding effect, and can effectively improve the welding efficiency and quality of the film roll. It should be noted that the heating plate 405 is made of a special high-temperature heat-resistant material, such as ceramic fiber board or similar material, which can withstand the high temperature required during the welding process and has good thermal conductivity, ensuring that heat is evenly transferred to the overlapping part of the new and old roll film in a short time, so as to achieve a stable and reliable welding effect. Meanwhile, the surface of the heating plate 405 is specially treated to be smooth and flat, making it difficult for roll film material to adhere. In addition, the design of the welding module 4 also takes safety factors into consideration. A heat insulation layer is set around the heating plate 405 to effectively prevent operators from being burned during use and ensure production safety.

[0026] Furthermore, the support module 6 also includes a third electric push rod 602 fixed to the fixed frame 601, and the other end of the third electric push rod 602 is fixed to the support plate frame 603. The top of the support plate frame 603 is connected to the bottom plate 604 through a groove. After the equipment stops running, by controlling the extension and retraction of the third electric push rod 602, the position of the support frame 603 can be precisely adjusted to avoid the end of the old roll film exceeding the cutter 504 when the machine stops, which would prevent accurate cutting. By moving the support frame 603 through the third electric push rod 602, the end of the old roll film can be adjusted to a suitable position so that it is within the range that the cutter 504 can effectively cut. The base plate 604 protects the support frame 603. The base plate 604 and the support frame 603 are connected by a groove, which facilitates disassembly and replacement. When the surface of the base plate 604 is worn or too much film material adheres and affects its use, a new base plate 604 can be quickly replaced to ensure the stability of the support effect.

[0027] Multiple guide rollers are rotatably connected between the inner walls of both sides of the frame 3 to guide the film roll. These guide rollers are distributed at different positions on the frame 3, forming a smooth film roll transport path. During film loading and subsequent processing, the guide rollers can effectively guide the film roll to move along a predetermined route, preventing the film roll from deviating or tangling, and ensuring the stable operation of the film roll within the slitting machine body 1. Meanwhile, the surface of the guide roller is specially treated to have a smooth texture, which reduces the friction between the film roll and the guide roller, reduces the damage to the film roll during transmission, and further improves the quality and efficiency of film roll processing. Moreover, the installation position and angle of the guide rollers have been carefully designed, and together with other components of the slitting machine body 1, they form an efficient and stable film processing system.

[0028] It also includes a straightening module 7, which is set above the feeding end 2 and is used to lock the head of the new roll film. The straightening module 7 includes two fourth electric push rods 701 fixed on the inner walls of both sides of the frame 3. The movable ends of the two fourth electric push rods 701 are fixed with connecting seats 702 that are slidably connected to the frame 3 by bolts. An auxiliary roller 703 is rotatably connected between the two connecting seats 702. A fixed roller 704 is rotatably connected between the inner walls of both sides of the frame 3. After the fourth electric push rod 701 is extended, the auxiliary roller 703 contacts the fixed roller 704. The new roll film passes through the auxiliary roller 703 and passes under the fixed roller 704. After the new roll of film is fed, the fourth electric push rod 701 is activated, which extends and pushes the connecting seat 702 to move inward to the frame 3, thereby driving the auxiliary roller 703 to approach the fixed roller 704 until the auxiliary roller 703 and the fixed roller 704 are in close contact. At this time, the new roll of film is clamped between the auxiliary roller 703 and the fixed roller 704, realizing the locking of the head of the new roll of film, effectively preventing the new roll of film from shifting or shaking during the feeding process, and ensuring that the new roll of film can enter the subsequent processing process accurately and stably. The design of the correction module 7 is simple and practical. Through the precise control of the electric push rod, it can quickly complete the locking action of the new film roll head, improving the efficiency and accuracy of feeding. Meanwhile, the surfaces of the auxiliary roller 703 and the fixed roller 704 are both smoothed to reduce friction with the new roll film, avoid damage to the new roll film, and ensure the quality of the roll film. When the equipment is started or other operations are performed, simply control the fourth electric push rod 701 to retract, so that the auxiliary roller 703 separates from the fixed roller 704, and the new roll of film can work normally. The operation is convenient and quick. In addition, the straightening module 7 coordinates with other components of the slitting machine body 1 to provide a strong guarantee for the stable processing of the film roll.

[0029] It should be noted that the first electric push rod 401, the second electric push rod 403, the third electric push rod 602 and the fourth electric push rod 701 are all existing technologies. They are used in conjunction with magnetic switches, proximity switches or photoelectric switches to achieve precise control of the push rod extension and retraction displacement. Those skilled in the art can set them according to actual needs.

[0030] The working principle of this utility model: When it is necessary to weld new and old roll film, stop the operation of the equipment. At this time, the tail end of the old roll film is located on the support frame 603. By adjusting the height of the cutter 504, the cutter 504 is brought into contact with the tail end of the old roll film. The mounting base 503 is pulled to move on the guide rod 502, so that the old roll film is cut with the cooperation of the support frame 603. After cutting, overlap the front end of the new roll film with the tail end of the old roll film. Activate the first electric push rod 401 to push the two slide blocks 402 to slide relative to each other on the top of the frame 3, so that the two heating plates 405 move to both sides of the tail end of the old roll film. At this time, activate the second electric push rod 403 to push the mounting frame 404 downward until the heating plate 405 is in close contact with the overlapping part of the new and old roll films. The heating plate 405 is powered on and heated to heat and weld the overlapping part. After the welding is completed, the equipment is restarted to allow the welded roll film to continue the subsequent slitting process. The motor in the slitting module drives the cutter to rotate and slit the film roll according to the preset specifications, dividing the wide film roll into multiple narrow film rolls.
