Description

Technical Field

[0001] This utility model relates to the field of edge trimming equipment technology, and in particular to a rapid edge trimming device for denim production. Background Technology

[0002] Denim, also known as denim fabric, is a type of coarse cotton fabric specifically used to make jeans. Originally, denim was only blue and was initially used as canvas, but now it comes in many different colors to match various clothing items. Denim is primarily made of cotton, but it has also evolved to incorporate various raw materials, including blends of natural fibers such as cotton, wool, silk, and linen, as well as blends with synthetic fibers. It also uses elastic yarn, tightly twisted yarn, and fancy yarn as raw materials. The main types of denim include bromo-indigo (commonly known as turquoise in the market) denim and sulfur black denim, as well as denim in colors such as coffee, emerald green, gray, khaki, and sulfur blue, which are colored using sulfur dyes. There are also small quantities of denim dyed with naphthol or reactive dyes in colors such as bright red, peach, and fuchsia.

[0003] Denim fabric requires edge trimming during production to ensure neat edges that meet subsequent processing requirements. However, most existing edge trimming equipment has a fixed structure and cannot be adapted to different denim sizes, lacking flexibility. Furthermore, changing the edge trimming size usually requires stopping the machine and manually disassembling parts of the structure for adjustment, which is cumbersome, time-consuming, and affects production efficiency and continuity.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] A denim fabric quick edge cutting device for denim production includes a rectangular frame 1. A rotating shaft 2 is rotatably connected inside the rectangular frame 1. A guide roller 3 is fixedly installed on the outer surface of the rotating shaft 2. A denim fabric body 4 is wrapped around the outer surface of the guide roller 3. Slide grooves 9 are provided on both sides inside the rectangular frame 1. An inner eight-slide rail 5 slides between the two sets of slide grooves 9. A telescopic rod 6 is fixedly installed between the inner eight-slide rail 5 and the inner wall of the rectangular frame 1. A horizontal bar slide rail 8 is provided on the upper side of the inner eight-slide rail 5. A vertical rod 7 is fixedly installed between the horizontal bar slide rail 8 and the inner wall of the rectangular frame 1. A slider 10 is slidably connected inside the horizontal bar slide rail 8. A rotating rod 11 is slidably connected inside the inner eight-slide rail 5. The slider 10 is fixedly installed on the outer surface of the rotating rod 11. A support member 12 is fixedly installed at the upper end of the rotating rod 11. A cutting machine 13 is provided at the end of the support member 12.

[0024] A spring 14 is fixedly installed between the support member 12 and the slider 10, and the spring 14 is sleeved on the outer surface of the rotating rod 11.

[0025] When it is necessary to adjust the trimming size of the cutting machine 13, the inner eight slide rail 5 is driven to move by activating the telescopic rod 6. The inner eight slide rail 5 and the crossbar slide rail 8 are symmetrically arranged in two sets. The rotating rod 11 is slidably connected inside the inner eight slide rail 5 and fixedly connected to the slider 10 slidably connected inside the crossbar slide rail 8. Therefore, under the combined action of the inner eight slide rail 5 and the crossbar slide rail 8, the rotating rod 11 will be driven to move inward. The support member 12 set at the upper end of the rotating rod 11 and the cutting machine 13 on the support member 12 will move synchronously. In this way, the displacement data of the cutting machine 13 can be selected as needed.

[0026] An extension rod 15 is fixedly installed at the lower end of the rotating rod 11, and an extension sleeve 16 is slidably connected between the two sets of extension rods 15. The extension sleeve 16 is fitted onto the outer surface of the two sets of extension rods 15.

[0027] The rectangular frame 1 has two sets of fixing parts 17 fixedly installed inside, and the two sets of fixing parts 17 are rotatably connected by a support shaft 18.

[0028] A coil spring 19 is fixedly installed at one end of the support shaft 18, and the other end of the coil spring 19 is fixedly connected to the fixing member 17.

[0029] A gear 20 is fixedly installed in the middle of the outer surface of the support shaft 18. A rack 21 meshes with the upper side of the gear 20. The rack 21 is fixedly connected to the inner eight slide rail 5.

[0030] Two sets of semi-protrusions 22 are fixedly installed on the outer surface of the support shaft 18, and the two sets of semi-protrusions 22 are symmetrically arranged on both sides of the gear 20.

[0031] Secondly, the inner eight-slide rail 5 will also push the rack 21 to move. The rack 21 meshes with the gear 20 on the support shaft 18. Therefore, when the rack 21 moves, it will drive the gear 20 to rotate, causing the gear 20 to drive the semi-protrusion 22 to rotate and abut against the extension sleeve 16. There are multiple sets of semi-protrusions 22, which are evenly distributed on the outer surface of the fixed shaft. Therefore, this device can be designed with multiple gear positions according to the number of semi-protrusions 22. Under the combined action of the coil spring 19 and the rack 21, the semi-protrusions 22 are always abutted against the extension sleeve 16 during the movement of the rack 21. The rotating rod 11 is lowered, compressing the spring 14. This allows the cutting machine 13 to descend during adjustment, preventing it from contacting the denim body 4. When the adjustment reaches the point where there are no semi-protrusions 22, the semi-protrusions 22 and the extension sleeve 16 are released from their abutment. Under the action of the spring 14, the rotating rod 11 carries the cutting machine 13 upward for cutting. As the rack 21 continues to push, different semi-protrusions 22 will intermittently abut against the extension sleeve 16, thus achieving different cutting sizes for the cutting machine 13 at different adjustment levels.

[0032] Denim fabric requires edge trimming during production to ensure neat edges that meet subsequent processing requirements. However, most existing edge trimming equipment has a fixed structure and cannot be adapted to different denim fabric sizes, lacking flexibility. Furthermore, changing the edge trimming size usually requires stopping the machine and manually disassembling parts of the structure for adjustment, which is cumbersome, time-consuming, and affects production efficiency and continuity. Therefore, this invention achieves adaptive adjustment of the edge trimming of denim fabric body 4 for different sizes by setting an inner eight-slide rail 5 and a crossbar slide rail 8 in cooperation. The structure is flexible and has a wide adjustment range. At the same time, the linkage design of the semi-protrusion 22 and the gear 20 enables the equipment to achieve non-stop adjustment during operation, avoiding the efficiency loss caused by the need to stop and disassemble traditional equipment.

[0033] Working principle: When it is necessary to adjust the trimming size of the cutting machine 13, the inner eight slide rail 5 is driven to move by activating the telescopic rod 6. The inner eight slide rail 5 and the cross bar slide rail 8 are symmetrically arranged in two sets. The rotating rod 11 is slidably connected inside the inner eight slide rail 5 and fixedly connected to the slider 10 slidably connected inside the cross bar slide rail 8. Therefore, under the combined action of the inner eight slide rail 5 and the cross bar slide rail 8, the rotating rod 11 will be driven to move inward. The support member 12 set at the upper end of the rotating rod 11 and the cutting machine 13 on the support member 12 will move synchronously. In this way, the displacement data of the cutting machine 13 can be selected as needed.

[0034] Secondly, the inner eight-slide rail 5 will also push the rack 21 to move. The rack 21 meshes with the gear 20 on the support shaft 18. Therefore, when the rack 21 moves, it will drive the gear 20 to rotate, causing the gear 20 to drive the semi-protrusion 22 to rotate and abut against the extension sleeve 16. There are multiple sets of semi-protrusions 22, which are evenly distributed on the outer surface of the fixed shaft. Therefore, this device can be designed with multiple gear positions according to the number of semi-protrusions 22. Under the combined action of the coil spring 19 and the rack 21, the semi-protrusions 22 are always abutted against the extension sleeve 16 during the movement of the rack 21. The rotating rod 11 is lowered, compressing the spring 14. This allows the cutting machine 13 to descend during adjustment, preventing it from contacting the denim body 4. When the adjustment reaches the point where there are no semi-protrusions 22, the semi-protrusions 22 and the extension sleeve 16 are released from their abutment. Under the action of the spring 14, the rotating rod 11 carries the cutting machine 13 upward for cutting. As the rack 21 continues to push, different semi-protrusions 22 will intermittently abut against the extension sleeve 16, thus achieving different cutting sizes for the cutting machine 13 at different adjustment levels.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
