Description

Technical Field

[0001] This utility model relates to the field of slitting machine equipment technology, and in particular to a quantitative slitting machine for nylon carpets. Background Technology

[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass yarn, or chemically synthesized fibers, through hand or machine processes of weaving, tufting, or spinning. Nylon carpets are made from nylon fibers. Nylon fibers have outstanding abrasion resistance among all fibers, allowing the carpet to maintain its appearance and performance for a long time. They are not easily worn, and the smooth surface of nylon fibers does not easily attract dust and stains. They also have strong stain resistance and stain-resistant properties, with a low absorption rate of stains and liquids.

[0003] During the production and processing of nylon carpets, they often need to be slit according to design requirements to cut the carpets into appropriate sizes. In the production process, carpets are often designed with many styles and different specifications to meet different needs. During the slitting process, the two ends of the carpet often need to be pressed to prevent the carpet from shifting during slitting. Reference document CN221480386U provides a carpet cutting device. The fixing device can effectively fix the carpet, keep the carpet in a taut state, and prevent the carpet from curling during cutting, which would cause dimensional deviations.

[0004] The above solutions can only cut carpets horizontally, which cannot meet the needs when carpets need to be slit. In addition, the sliding blade holder structure in the above solutions is relatively simple and cannot be replaced or added as needed. After long-term cutting, the blades installed on the sliding blade holder often wear out. If the blades are not replaced, it will affect the subsequent cutting efficiency, and the cut carpet is also prone to burrs. In the existing technology, it is not possible to quickly replace the blades. To address the above problems, a solution is proposed below. Utility Model Content

[0020] See Figures 1 to 5 As shown, a quantitative slitting machine for nylon carpets includes a slitting table 1. The top two sides of the slitting table 1 are also provided with pressing components 11 for pressing the carpet for conveying. When the carpet needs to be slitting, the carpet can be passed through the pressing components 11 first, and the pressing components 11 press the carpet for conveying, so that the carpet can be conveyed taut. One end of the slitting table 1 is also provided with a take-up roller, and one end of the carpet is connected to the take-up roller. The take-up roller pulls the carpet for conveying, which facilitates subsequent cutting.

[0021] The pressing assembly 11 includes a support frame 3 12, two conveyor rollers 13 and two conveyor rollers 2 14. The support frame 3 12 is respectively installed on both sides of the top of the slitting table 1. The top of the slitting table 1 also has two wide slots 1 corresponding to the support frame 1 2. The conveyor rollers 13 are rotatably mounted in the wide slots 1. Two drive motors 2 15 are also installed on the side wall of the slitting table 1. The output shafts of the two drive motors 2 15 pass through the slitting table 1 and are fixedly connected to the conveyor rollers 13. The conveyor rollers 2 14 are rotatably mounted inside the support frame 1 2. The conveyor rollers 2 14 and the conveyor rollers 13 are arranged opposite to each other. When the carpet needs to be processed, it will first be fed from the conveyor rollers 13 and 2 14. The carpet passes between conveyor rollers 13 and 14. A cylinder is installed on the top of support frame 3 12, and a connecting frame is installed inside support frame 3 12. Conveyor roller 2 14 is rotatably mounted on the connecting frame. The piston rod of the cylinder is fixed on the top of the connecting frame. When the carpet passes between conveyor roller 13 and conveyor roller 2 14, the cylinder can be activated. The piston rod of the cylinder pushes the connecting frame to move, so that conveyor roller 2 14 can be combined with conveyor roller 13 to press the carpet. At this time, drive motor 2 15 can be activated. The output shaft of drive motor 2 15 drives conveyor roller 13 to rotate. The rotation of conveyor roller 13 pushes the carpet to be conveyed.

[0022] A support frame 2 is also slidably mounted on the slitting table 1. The slitting table 1 is equipped with a drive assembly 3 for moving the support frame 2. In order to meet production requirements, the support frame 2 is designed as a movable structure, so that the support frame 2 can be adjusted to different positions as needed, thereby adapting to different work requirements.

[0023] The drive assembly 3 includes a lead screw 31 and a slide bar 32. Wide slots 2 33 are respectively opened on both sides of the slitting table 1. A wide slot 34 is opened on one side wall of the slitting table 1. A servo motor 1 35 is installed in the wide slot 34. The lead screw 31 is rotatably mounted in one wide slot 2 33. The output shaft of the servo motor 1 35 passes through the wide slot 34 and is fixedly connected to the lead screw 31. The slide bar 32 is installed in the other wide slot 2 33. Sliding sliders 36 are slidably mounted on both the lead screw 31 and the slide bar 32. One side slider 36 is threadedly fitted to the lead screw 31. The two ends of the support frame 2 4 are fixedly connected to the sliders 36 on both sides. When it is necessary to move the support frame 2 4, the servo motor 1 35 can be started first. The output shaft of the servo motor 1 35 drives the lead screw 31 to rotate. The rotation of the lead screw 31 will drive the slider 36, which is threaded with it, to slide in the wide groove 2 33. The sliding of the slider 36 can drive the support frame 2 to slide. The support frame 2 can drive the slider 36 on the other side to slide on the slide rod 32. The slide rod 32 plays the role of limiting the sliding of the support frame 2.

[0024] Support frame 2 is installed on the inner side of support frame 1 2. A drive component 5 for pushing support frame 1 2 is installed on the top of support frame 1 2. Support rod 6 is installed on the inner wall of support frame 2 4. Multiple mounting knife holders 7 are installed on support rod 6. A disassembly component 8 is provided between the mounting knife holders 7 and support rod 6. When it is necessary to cut the carpet, the corresponding number of mounting knife holders 7 can be installed according to the actual number of carpets to be cut. The mounting knife holders 7 are installed on support rod 6, and the support rod 6 is used to support and fix the mounting knife holders 7.

[0025] The tool holder 7 is divided into an upper tool holder 71 and a lower tool holder 72. The slot 9 and threaded hole are both located on the lower tool holder 72. A fixing bolt is threaded onto the top of the upper tool holder 71. The top of the support rod 6 is a flat structure, and the bottom of the fixing bolt abuts against the top surface of the support rod 6. The upper tool holder 71 is fixed to the support rod 6 by the fixing bolt. The disassembly component 8 includes two locking blocks 81, both fixed to the bottom sides of the upper tool holder 71. The top of the lower tool holder 72 has an assembly slot 82 corresponding to the locking blocks 81. The two locking blocks 81 are respectively installed in the two assembly slots 82. When the tool holder 7 needs to be installed onto the support rod 6, the upper tool holder 71 can be installed onto the support rod 6 first, and then the lower tool holder 72 can be aligned with the upper tool holder 71 by inserting the locking blocks 81 of the upper tool holder 71 into the lower tool holder 72. Within the assembly slot 82 of the blade holder 72, the locking block 81 engages with the assembly slot 82, thus enabling the installation of the upper blade holder 71 and the lower blade holder 72. To improve the stability of the installation between the upper blade holder 71 and the lower blade holder 72, locking bolts are provided on both sides of the lower blade holder 72 for further securing the locking block 81. The locking bolts further enhance the stability of the upper blade holder 71 and the lower blade holder 72. After the blade holder 7 is installed, it can be moved to the designated position according to the required cutting width of the carpet. After the blade holder 7 is moved to the designated position, the fixing bolts can be tightened to secure the blade holder 7 through the abutment between the fixing bolts and the top surface of the support rod 6, preventing the blade holder 7 from shifting position during subsequent use.

[0026] Each mounting blade holder 7 has a slot 9 at its bottom, on which a cutting blade 10 is slidably mounted. One end of the cutting blade 10 is installed in the slot 9. A threaded hole is provided on the side wall of the mounting blade holder 7, communicating with the inside of the slot 9. A through hole corresponding to the threaded hole is provided on the end face of the cutting blade 10, with a locking bolt threaded into the threaded hole. The cutting blade 10 is fixed in the slot 9 by the locking bolt. The mounting blade holder 7 achieves carpet cutting by installing the cutting blade 10 at its bottom. The drive component 5 can be an electric push rod. When cutting, the electric push rod can be started first. The electric push rod will push the support frame 2 4 to rise and fall. The support frame 2 4 drives the support rod 6 and the blade holder 7 to rise and fall, so that the cutting blade 10 can be moved to the specified height. The highest point of the conveyor roller 13 is higher than the top surface of the slitting table 1. Therefore, the carpet will not come into contact with the top surface of the slitting table 1 when it is being conveyed. This makes it easier for the cutting blade 10 to cut the carpet better. When the cutting blade 10 is damaged after long-term use, it can be replaced by tightening the locking bolt.

[0027] Working principle: When the carpet needs to be cut, the carpet can be passed through the pressing components 11 on both sides. The pressing components 11 press the carpet and start the drive motor 15 in the pressing components 11 so that the conveying roller 13 can transport the carpet. The drive component 5 pushes the mounting knife holder 7 to adjust the height. The mounting knife holder 7 can drive the bottom cutting blade 10 to the specified height. During the conveying process, the carpet can be cut by the cutting blade 10. The mounting knife holder 7 can be detached from the support rod 6 through the disassembly component 8. The number of mounting knife holders 7 can be adjusted according to the actual cutting quantity to adapt to different processing scenarios.
