Technical Field

[0001] This utility model relates to the field of seat belt production, specifically a cutting device for automobile seat belt production. Background Technology

[0002] In the manufacturing process of automotive seat belts, a cutting device is typically used to cut the seat belts to ensure that their size and shape meet standard requirements. Existing automotive seat belt cutting devices usually include a feeding system, a cutting mechanism, and a control system. The feeding system is generally equipped with a roller-type feeding mechanism to facilitate continuous material feeding for cutting.

[0003] When seat belts are cut with a blade, a large amount of broken fiber waste is generated, which will accumulate on the surface of the feeding guide roller, affecting the subsequent processing of the seat belt. After long-term use, the surface of the feeding guide roller is easily damaged by friction, resulting in loss of the squeezing effect and inability to move the seat belt material. However, the disassembly process of the feeding roller is relatively cumbersome, requiring the use of special tools and taking a long time. This not only reduces production efficiency but also increases maintenance costs and workload. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0016] A cutting device for producing automotive seat belts includes a cutting machine 1. A mounting component 2 is mounted on the top of the cutting machine 1, and a feeding roller 3 is mounted in the middle of the mounting component 2. The cutting machine 1 includes a cutting machine frame 11, with a placement plate 16 fixedly connected to the top of the frame 11. The mounting component 2 includes two fixing blocks 21, the bottoms of which are fixedly connected to the placement plate 16. Two rotating shafts 22 are fixedly connected to the middle of each fixing block 21, and a spring sleeve 23 is fixedly connected to the middle of each rotating shaft 22. A square insert 24 is slidably connected to the inner wall of the spring sleeve 23 via an anti-detachment block. The square insert 24 passes through the spring sleeve. One end of the spring sleeve 23 is provided with an inclined surface. The feeding roller 3 includes a feeding roller body 31. Two isolation plates 32 are fixedly connected to the outer wall of the feeding roller body 31. Mounting blocks 33 are fixedly connected to both ends of the feeding roller body 31. A slot 34 is opened on one side of the mounting block 33. A fixing groove 35 is connected through one end of the slot 34. The inner wall of the fixing groove 35 is slidably connected to the square insert 24. A connecting rod 25 is fixedly connected to the end of the spring sleeve 23 away from the square insert 24. A cleaning cotton block 26 is fixedly connected to one side of the connecting rod 25. The cleaning cotton block 26 is in contact with the outer surface of the feeding roller body 31.

[0017] It should be noted that when the outer wall of the feeding roller body 31 is contaminated with a lot of fiber waste over a long period of time, resulting in increased friction and damage to the transmission effect of the feeding roller 3, the operator can pull the square insert 24 to slide in the fixed groove 35, causing the anti-detachment block to slide on the inner wall of the spring sleeve 23 until the square insert 24 slides out from the inner wall of the fixed groove 35. The feeding roller 3 can then be removed and replaced. The side of the fixed groove 35 with the slot 34 facing down is aligned with the top inclined surface of the square insert 24 and pressed down. The square insert 24 retracts into the fixed block 21 and slides along the slot 34. At the same time, the anti-detachment block compresses the spring to generate elastic potential energy until the square insert 24 reaches the inner wall of the fixed groove 35. The spring releases the elastic potential energy and pushes the square insert 24 into the fixed groove 35 for fixation.

[0018] Three limiting openings 18 are provided on one side of the placement plate 16, and a drop opening 17 is provided on the top of the placement plate 16. A recycling box 12 is slidably connected to the bottom of the cutting machine frame 11. A shearing plate 15 is fixedly connected to one side of the placement plate 16. A transmission structure 13 is fixedly connected inside the cutting machine frame 11. A movable frame 14 is fixedly connected to the top of the transmission structure 13. A blade is provided on the top and bottom surfaces of the movable frame 14, and the bottom of the blade can be inserted into the shearing plate 15.

[0019] It should be noted that during use, the operator can pass three rolled-up safety belt materials through the gap between the movable frame 14 and the shearing plate 15, through the gap between the feeding roller body 31 and the placement plate 16 via the partition plate 32, and finally through the corresponding limit port 18. After adjusting to the required length, the motor is started, which drives the movable frame 14 to move up and down. The movable frame 14 drives the cutter to insert into the shearing plate 15 to cut the safety belt materials. Then, the motor drives the spring sleeve 23 to rotate through the rotating shaft 22, causing the spring sleeve to... 23 drives the square insert 24 to rotate, which in turn drives the feeding roller 3 to rotate and assist the safety belt material to rotate and unwind. The safety belt material enters the cutting machine frame 11 under the guidance of the feeding roller body 31 and is sheared by the blades on the movable frame 14. After the safety belt material is cut, fiber waste is generated and it adheres to the outer wall of the feeding roller body 31. At this time, the cleaning cotton block 26 connected by the connecting rod 25 scrapes off the waste adhering to the surface of the feeding roller body 31 and drops it into the drop outlet 17, where it is recycled into the recycling box 12.

[0020] During use, the operator can pass three rolled-up safety belt materials through the gap between the movable frame 14 and the shearing plate 15, through the gap between the feeding roller body 31 and the placement plate 16 via the partition plate 32, and finally through the corresponding limit port 18. After adjusting to the required length, the motor is started, which drives the movable frame 14 to move up and down. The movable frame 14 drives the blade to insert into the shearing plate 15 to cut the safety belt material. Then, the motor drives the spring sleeve 23 to rotate via the rotating shaft 22, causing the spring sleeve 23 to drive the square insert 24 to rotate. The square insert 24 drives the feeding roller 3 to rotate to assist the rotation and unwinding of the safety belt material. Under the guidance of the feeding roller body 31, the safety belt material enters the cutting machine frame 11 and is sheared by the blade on the movable frame 14. After being cut, the safety belt material produces fiber waste, which adheres to the outer wall of the feeding roller body 31. At this time, it is discharged through the connecting rod 2. The cleaning cotton block 26 connected to 5 scrapes the waste material adhering to the surface of the feeding roller body 31 and drops it into the drop port 17, where it is recycled into the recycling box 12. When the outer wall of the feeding roller body 31 is covered with a lot of fiber waste due to long-term adhesion, resulting in increased friction and damage to the transmission effect of the feeding roller 3, the operator can pull the square insert 24 to slide in the fixed groove 35, causing the anti-detachment block to slide on the inner wall of the spring sleeve 23 until the square insert 24 slides out from the inner wall of the fixed groove 35. The feeding roller 3 can then be removed and replaced. The side of the fixed groove 35 with the slot 34 facing down is aligned with the top inclined surface of the square insert 24 and pressed down. The square insert 24 retracts into the fixed block 21 and slides along the slot 34. At the same time, the anti-detachment block compresses the spring to generate elastic potential energy until the square insert 24 reaches the inner wall of the fixed groove 35. The spring releases the elastic potential energy and pushes the square insert 24 into the fixed groove 35 for fixation.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
