DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] refer to Figure 1-8 , the production process of antibacterial and anti-wrinkle knitted fabrics, the production process is as follows; S1. Mix bamboo fiber and polyester fiber according to the proportion. Mixing the two fibers can complement each other's advantages. Bamboo fiber provides natural antibacterial properties, breathability and softness, while polyester fiber enhances the durability, elasticity and wrinkle resistance of the fabric. The blended fabric is soft and comfortable while having higher strength and durability, which prolongs the service life of the fabric. S2, opening bamboo fiber, polyester fiber and polyurethane fiber respectively, then evenly mixing the opened bamboo fiber and polyester fiber, and then placing the polyurethane fiber alone aside; opening bamboo fiber can make its fiber bundles looser and more uniform, which helps to improve the softness and comfort of bamboo fiber, and at the same time makes it easier to blend with other fibers or carry out subsequent processing. The opening of polyester fiber is mainly to adjust the arrangement of its fiber bundles to make them more even and neat; S3. Comb the mixed bamboo fiber and polyester fiber, then comb the polyurethane fiber, and finally pass the mixed bamboo fiber and polyester fiber through a drawing frame for drawing; drawing refers to combining two or more different types of fibers into a fiber strip through a drawing frame for subsequent spinning processing. Through the drawing process, the fibers can be effectively mixed together, providing uniform and consistent fiber strips for the subsequent spinning and weaving processes. The combing step ensures further separation and arrangement of the fibers, making the distribution of the fibers in the blended yarn more uniform. This step can improve the strength and smoothness of the yarn, reduce impurities and short fibers in the yarn, and improve the quality of the finished fabric; S4, spinning the drawn bamboo fiber and polyester fiber to obtain a blended yarn of bamboo fiber and polyester fiber, and then spinning the polyurethane fiber to obtain a stretch yarn; S5, knitting the blended yarn and the elastic yarn into an antibacterial layer 7 and an elastic layer 8 through a circular knitting machine respectively; S6, placing the woven antibacterial layer 7 and elastic layer 8 on a rewinding device, and bonding the antibacterial layer 7 and elastic layer 8 to form a knitted fabric 10 through the rewinding device. By attaching an elastic layer 8 woven from polyurethane fiber to one side of the antibacterial layer 7, the fabric has excellent elasticity. When the fabric is stretched or wrinkled, the elastic layer 8 can drive the fabric to quickly return to its original shape to avoid permanent deformation. Secondly, the elastic layer 8 can help the fabric stay flat after long-term wearing or repeated washing, avoiding wrinkles that affect the beauty of the clothing.

[0021] Specifically, the rewinding equipment includes a frame 1, a rewinding mechanism arranged on the frame 1 and rotatably connected to the frame 1, and a driving mechanism that drives the rewinding mechanism to work. The rewinding mechanism includes a first feeding roller 101 on which the elastic layer 8 is placed, a first tensioning roller 102, a first guide roller 103, a second guide roller 104, a second tensioning roller 105 and a rewinding roller 106, and the first feeding roller 101, the first tensioning roller 102, the first guide roller 103, the second guide roller 104, the third tensioning roller 201 and the rewinding roller 106 are arranged in sequence on the frame 1, the first feeding roller 101 is connected to the rewinding roller 106 by a first synchronous pulley set, the first guide roller 103 and the second guide roller 104 are at the same horizontal height, and the frame 1 is also provided with a bonding mechanism for bonding the antibacterial layer 7 and the elastic layer 8 together.

[0022] The antibacterial layer 7 and the elastic layer 8 are bonded by a rewinding device, so that the two materials can be bonded in a continuous process. Compared with manual or multi-step processing, this automated production method not only significantly reduces the complexity of manual operation, but also greatly improves production efficiency.

[0023] Furthermore, the bonding mechanism includes a second feeding roller 2 (the second feeding roller 2 is used to place the antibacterial layer 7), a third tensioning roller 201, a third guide roller 202 (the horizontal height of the third guide roller 202 is higher than the first guide roller 103), a bonding roller 203 for applying adhesive to the surface of the elastic layer 8, and a fourth guide roller 204, which are arranged on the frame 1 and are arranged in sequence and rotatably connected to the frame 1. The second feeding roller 2 is arranged on the side of the first feeding roller 101 away from the first tensioning roller 102, and the second feeding roller 2 is connected to the first feeding roller 101 through a second synchronous belt pulley set. The bonding roller 203 (the staff can regularly apply adhesive on the bonding roller 203) and the fourth guide roller 204 are both arranged between the first guide roller 103 and the second guide roller 104. In between, the bonding roller 203 is arranged on the side close to the first guide roller 103, and two support frames 205 are arranged on the frame 1 on the side close to the second guide roller 104, and the two ends of the fourth guide roller 204 are respectively rotatably connected to the support frames 205, and the top of each support frame 205 is provided with an extrusion groove 206, and each extrusion groove 206 is slidably connected with an extrusion block 207, and the two extrusion blocks 207 are connected through an extrusion roller 209, and the extrusion roller 209 is rotatably connected to the extrusion block 207, and a first elastic member 208 is arranged in the extrusion groove 206 (the first elastic member 208 in the illustrated state is in a compressed state), and one end of the first elastic member 208 is fixedly connected to the top of the extrusion groove 206, and the other end of the first elastic member 208 is fixedly connected to the extrusion block 207.

[0024] During use, first, the staff needs to place the elastic layer 8 on the first unwinding roller 101, and pass one side of the elastic layer 8 around the bottom of the first tensioning roller 102, and then pass around the top of the first guide roller 103. Then, the surface of the elastic layer 8 is brought into contact with the surface of the bonding roller 203, and the bottom of the elastic layer 8 is brought into contact with the top surface of the fourth guide roller 204. Since the first guide roller 103 and the second guide roller 104 are at the same level, the elastic layer 8 remains horizontal between the two guide rollers, and then passes around the top of the second guide roller 104. Then, the elastic layer 8 passes around the bottom of the second tensioning roller 105, and finally, one side of the elastic layer 8 is fixed on the winding roller 106.

[0025] Next, the staff needs to place the antibacterial layer 7 on the second unwinding roller 2, pass one side of the antibacterial layer 7 around the bottom of the third tensioning roller 201, then around the top of the third guide roller 202, and finally around the bottom of the squeezing roller 209. Since the squeezing roller 209 is rotatably connected to the squeezing block 207, and the squeezing block 207 is connected to the squeezing groove 206 by sliding, the staff can lift the squeezing roller 209 to a certain height so that the bottom of the antibacterial layer 7 contacts the surface of the elastic layer 8. Then, release the hand, the first elastic member 208 will restore the deformation, and drive the squeezing roller 209 to squeeze the surface of the antibacterial layer 7 and the elastic layer 8 through the squeezing block 207. In this way, the connection between the two will be tighter, thereby ensuring that the contact surface between the antibacterial layer 7 and the elastic layer 8 is flat and tight, and improving the quality of the overall fabric. In addition, the first elastic member 208 is compressible, which enables the rewinding equipment to adapt to the connection between the antibacterial layer 7 and the elastic layer 8 of different thicknesses, expanding the scope of use of the rewinding equipment. Next, the antibacterial layer 7 is passed around the bottom of the second tension roller 105 , and the antibacterial layer 7 and the elastic layer 8 are bonded together by an adhesive, and the adhesive is applied on the surface of the bonding roller 203 .

[0026] Finally, the driving mechanism is started, and the driving mechanism will drive the winding mechanism to move, so that the first feeding roller 101 and the second feeding roller 2 start feeding. During the movement of the elastic layer 8, its surface will contact the bonding roller 203, and the adhesive on the surface of the bonding roller 203 will be smeared on the surface of the elastic layer 8. The elastic layer 8 continues to move toward the squeezing roller 209. When the elastic layer 8 with the adhesive contacts the antibacterial layer 7, the squeezing roller 209 will make the two tightly connected to form the knitted fabric 10. Then, the knitted fabric 10 will bypass the bottom of the second tensioning roller 105 under the action of the winding roller 106, and gradually wrap around the surface of the winding roller 106. In addition, an air drying mechanism (not shown) can be set between the fourth guide roller 204 and the winding roller 106 to speed up the drying process of the adhesive.

[0027] Furthermore, in order to prevent the sliding block 305 from being offset or misaligned when the staff moves the extrusion block 207, a first guide rod 210 is fixedly connected in the extrusion groove 206, and the extrusion block 207 is slidably connected to the first guide rod 210. The first elastic member 208 is sleeved on the outer surface of the first guide rod 210. The first guide rod 210 can prevent the extrusion block 207 from being offset or misaligned when the extrusion block 207 moves, thereby improving the stability of the movement of the extrusion block 207. Secondly, it can ensure that the first elastic member 208 is evenly stressed, thereby improving the service life of the first elastic member 208. In addition, sleeved on the outer surface of the first guide rod 210, the first elastic member 208 can be prevented from being offset or misaligned after long-term use, thereby further improving the service life of the first elastic member 208.

[0028] In this embodiment, in order to improve the bonding strength between the elastic layer 8 and the antibacterial layer 7, a pressing device capable of pressing the surface of the elastic layer 8 into a convex shape is provided between the first guide roller 103 and the glue roller. The convex structure can increase the contact area between the elastic layer 8 and the antibacterial layer 7, making the connection between the antibacterial layer 7 and the elastic layer 8 more secure. In addition, when the surface of the knitted fabric 10 is deformed, since the convex structure connects the antibacterial layer 7 and the elastic layer 8 more securely, the elastic layer 8 can more quickly drive the antibacterial layer 7 to recover the deformation, further improving the anti-wrinkle performance of the knitted fabric 10.

[0029] The pressing device includes a gantry 3 arranged on the frame 1, a pressing plate 301 for pressing the surface of the elastic layer 8, a bottom plate 302 arranged inside the gantry 3, a plurality of second elastic members 303, and a power mechanism for driving the pressing plate 301 to press down (the first elastic member 208 and the second elastic member 303 are both cylindrical compression springs), the inner walls of both sides of the gantry 3 are provided with sliding grooves 304, both sides of the pressing plate 301 are provided with sliding blocks 305, the sliding blocks 305 are slidably connected to the inner walls of the sliding grooves 304, and one end of each second elastic member 303 is connected to the sliding grooves 304. The bottom of the movable groove 304 is fixedly connected, the other end of the second elastic member 303 is fixedly connected to the sliding block 305, the pressure plate 301 is arranged above the bottom plate 302, and a plurality of grooves are provided on the side of the pressure plate 301 close to the bottom plate 302, and a plurality of protrusions 306 are provided on the side of the bottom plate 302 close to the pressure plate 301, and the position of each protrusion corresponds to the position of each groove one by one, respectively, sliding grooves 307 are provided on both sides of the gantry 3, and sliders 308 are provided on both sides of the sliding block 305, and the power mechanism is connected to the slider 308 and is linked to the driving mechanism.

[0030] The linkage design enables the pressing mechanism to operate synchronously with the winding mechanism to ensure that the protrusion structure is evenly distributed on the elastic layer 8. Secondly, the linkage design enables the entire production process to be completed in a continuous and automated process. The synchronous operation of pressing and winding reduces the dispersion of the production process, making the entire manufacturing process more compact and efficient. It not only reduces the need for manual operation, but also significantly improves production efficiency. In addition, the linkage design can also reduce the cost of the drive source and reduce the demand for electricity.

[0031] In order to prevent the pressure plate 301 from being offset or misplaced during movement, a second guide rod 309 is fixedly connected in the sliding groove 304, and the sliding block 305 is slidably connected to the second guide rod 309. By setting the second guide rod 309, the pressure plate 301 can be prevented from being offset or misplaced during movement, and at the same time, it is ensured that the protrusion on the bottom plate 302 is always aligned with the groove on the pressure plate 301, thereby ensuring the uniformity of the protrusion on the surface of the elastic layer 8.

[0032] Furthermore, the driving mechanism includes a first gear 4, an incomplete gear 1 401, an incomplete gear 2 402, a second gear 403 (the first gear 4 and the second gear 403 have the same specifications), and a rotating motor 404. The specifications of the incomplete gear 1 401 and the incomplete gear 2 402 are equal, and the specifications of the incomplete gear 1 401 and the first gear 4 are the same, except for the different number of teeth.

[0033] The first unloading roller 101 is rotatably connected to the frame 1 through the first rotating shaft 405, and one side of the first rotating shaft 405 extends out of the frame 1, and the first gear 4 is arranged on the first rotating shaft 405 and fixedly connected to the first rotating shaft 405. The frame 1 is rotatably connected to the second rotating shaft 406 on one side close to the first unloading roller 101, and the incomplete gear 1 401 and the incomplete gear 2 402 are both fixedly connected to the second rotating shaft 406, and the incomplete gear 1 401 is meshed with the first gear 4, and the output end of the rotating motor 404 is fixedly connected to the second rotating shaft 406, and the gear teeth on the incomplete gear 1 401 are arranged on the side close to the winding roller 106, and the gear teeth on the incomplete gear 2 402 are arranged on the side away from the winding roller 106, and the gear teeth on the incomplete gear 1 401 and the incomplete gear 2 402 are arranged in half (the half-and-half arrangement here is for better explanation) As shown in the figure, a complete gear has 16 teeth, while the incomplete gear 1 401 in this embodiment has 8 teeth, and all 8 teeth are arranged on one side of the incomplete gear 1 401, and there is no gear tooth on the other side. Then the 8 gear teeth on the incomplete gear 2 402 are all arranged on the other side opposite to the gear teeth on the incomplete gear 1 401. When the centers of the incomplete gear 1 401 and the incomplete gear 2 402 coincide, it is a complete gear when viewed from the front. The numbers appearing here are only for illustration and convenience of understanding. This embodiment does not limit the number of teeth of the incomplete gear 1 401). The second gear 403 is rotatably connected to the side of the frame 1 through the third rotating shaft 407, the second gear 403 is meshed with the incomplete gear 2 402, and the power mechanism is linked to the second gear 403 through the third synchronous pulley set.

[0034] Through the cooperation of the incomplete gear set, the pressing mechanism can perform the pressing action at a specified time point, and the winding mechanism continues to operate after the pressing is completed. This intermittent action ensures that the pressing of each protrusion can be completed at the optimal time, avoiding the errors that may occur during the continuous pressing process, thereby improving the accuracy and consistency of the protrusion structure.

[0035] Further, the power mechanism includes a first connecting rod 408, a second connecting rod 409, a third gear 410, and an incomplete gear 3 411. The incomplete gear 3 411 is rotatably connected to the side of the frame 1 through a fourth rotating shaft 412. The gear teeth on the incomplete gear 3 411 are arranged on the side away from the winding roller 106, and the gear teeth on the incomplete gear 3 411 are arranged in half. The third synchronous pulley set is connected to the fourth rotating shaft 412. The third gear 410 is rotatably connected to the side of the gantry 3 through the fifth rotating shaft 413, and the third gear 410 is meshed with the incomplete gear 3 411. One end of the first rotating shaft 405 is rotatably connected to the slider 308, and the other end of the first connecting rod 408 is rotatably connected to one end of the second connecting rod 409, and the other end of the second connecting rod 409 is fixedly connected to the fifth rotating shaft 413. Secondly, in order to increase the stability of the connecting rod action, the length of the first connecting rod 408 is set to be greater than the length of the second connecting rod 409. The mechanical transmission method of the connecting rod mechanism has high reliability and can maintain stable performance in multiple cycle operations.

[0036] The third synchronous pulley group includes a third large pulley 414 and a third small pulley 415. The third large pulley 414 is fixedly connected to the third rotating shaft 407, and the third small pulley 415 is fixedly connected to the fourth rotating shaft 412. The third large pulley 414 and the third small pulley 415 are connected by a transmission belt 416, and the diameter of the third large pulley 414 is twice that of the third small pulley 415.

[0037] Working principle: During use, the staff first needs to place the elastic layer 8 on the first unwinding roller 101, and pass one side of the elastic layer 8 around the bottom of the first tensioning roller 102, and then pass around the top of the first guide roller 103, then make the bottom of the elastic layer 8 contact the protrusion on the bottom plate 302, and make the surface of the elastic layer 8 contact the surface of the bonding roller 203, and then make the bottom of the elastic layer 8 contact the top surface of the fourth guide roller 204. Since the first guide roller 103 and the second guide roller 104 are at the same level, the elastic layer 8 remains horizontal between the two guide rollers, and then passes around the top of the second guide roller 104. Then the elastic layer 8 passes around the bottom of the second tensioning roller 105, and finally fixes one side of the elastic layer 8 on the winding roller 106.

[0038] Next, the staff needs to place the antibacterial layer 7 on the second unwinding roller 2, pass one side of the antibacterial layer 7 around the bottom of the third tensioning roller 201, then around the top of the third guide roller 202, and finally around the bottom of the squeezing roller 209. Since the squeezing roller 209 is rotatably connected to the squeezing block 207, and the squeezing block 207 is connected to the squeezing groove 206 by sliding, the staff can lift the squeezing roller 209 to a certain height so that the bottom of the antibacterial layer 7 contacts the surface of the elastic layer 8. Then, release the hand, the first elastic member 208 will restore the deformation, and drive the squeezing roller 209 to squeeze the surface of the antibacterial layer 7 and the elastic layer 8 through the squeezing block 207. In this way, the connection between the two will be tighter, thereby ensuring that the contact surface between the antibacterial layer 7 and the elastic layer 8 is flat and tight, and improving the quality of the overall fabric. In addition, the first elastic member 208 is compressible, which enables the rewinding equipment to adapt to the connection between the antibacterial layer 7 and the elastic layer 8 of different thicknesses, expanding the scope of use of the rewinding equipment. Next, the antibacterial layer 7 is passed around the bottom of the second tension roller 105 , and the antibacterial layer 7 and the elastic layer 8 are bonded together by an adhesive, and the adhesive is applied on the surface of the bonding roller 203 .

[0039] Finally, after the rotary motor 404 is started, its output end will drive the second rotating shaft 406 to rotate. When the rotary motor 404 rotates half a circle, since the gear teeth on the incomplete gear are arranged on the side close to the winding roller 106, the counterclockwise rotation of the second rotating shaft 406 will cause the incomplete gear to rotate counterclockwise and mesh with the first gear 4. In this way, the first gear 4 rotates half a circle, so that the first rotating shaft 405 rotates clockwise, and then drives the first unwinding roller 101 to rotate clockwise. The first unwinding roller 101 drives the second synchronous belt pulley group through the first synchronous belt pulley group, so that the second unwinding roller 2 and the winding roller 106 both rotate clockwise, and the winding roller 106 will rewind the knitted fabric 10.

[0040] During the movement of the elastic layer 8, its surface will contact the bonding roller 203, and the adhesive on the surface of the bonding roller 203 will be smeared on the surface of the elastic layer 8. The elastic layer 8 continues to move toward the squeezing roller 209. When the elastic layer 8 with the adhesive contacts the antibacterial layer 7, the squeezing roller 209 will tightly connect the two to form the knitted fabric 10. Then, the knitted fabric 10 will bypass the bottom of the second tensioning roller 105 under the action of the winding roller 106 and gradually wrap around the surface of the winding roller 106. In addition, an air drying mechanism (not shown) can be set between the fourth guide roller 204 and the winding roller 106 to speed up the drying process of the adhesive.

[0041] When the output end of the rotating motor 404 rotates from half a circle to one circle, since the other half of the incomplete gear 1 401 is not provided with gear teeth, the incomplete gear 1 401 will not drive the first gear 4 to rotate, thereby suspending the winding work of the knitted fabric 10. At the same time, the gear teeth on the incomplete gear 2 402 will drive the second gear 403 to rotate half a circle clockwise. The second gear 403 drives the third large pulley 414 to rotate half a circle through the third rotating shaft 407. Since the diameter of the third large pulley 414 is twice the diameter of the third small pulley 415, the third large pulley 414 drives the third small pulley 415 to rotate one circle through the conveyor belt 416.

[0042] When the third small pulley 415 rotates half a circle clockwise, it drives the incomplete gear three 411 to rotate half a circle clockwise through the fourth shaft 412. The gear teeth on the incomplete gear three 411 are set on the side away from the winding roller 106, so its clockwise rotation will cause the third gear 410 to rotate counterclockwise. This causes the fifth shaft 413 to rotate counterclockwise, thereby driving one end of the second connecting rod 409 to rotate counterclockwise, and the other end of the second connecting rod 409 further drives one end of the first connecting rod 408 to rotate counterclockwise. The other end of the first connecting rod 408 drives the slider 308 to move in the slide groove 307, pushing the sliding block 305 to move in the direction of compressing the second elastic member 303, so that the pressure plate 301 moves downward and presses down the surface of the elastic layer 8. Under the cooperation of the protrusion 306 of the bottom plate 302 and the groove of the pressure plate 301, a bulge is formed on the surface of the elastic layer 8. The purpose of disposing the bumps 306 on the bottom plate 302 instead of the pressing plate 301 is to reduce the contact area between the bottom of the elastic layer 8 and the bottom plate 302 , thereby improving the flatness of the bottom surface of the elastic layer 8 .

[0043] When the third small pulley 415 rotates from half a circle to a full circle, since the other side of the incomplete gear 3 411 has no gear teeth, it will not be able to drive the third gear 410 to rotate. At this time, each second elastic member 303 will return to its original state, so that the sliding block 305 and the slider 308 return to their initial positions, and the first connecting rod 408 and the second connecting rod 409 will also return to their original positions, so that the third gear 410 rotates clockwise to its original position. In this way, the rewinding equipment realizes the working process of winding, pressing and bonding at the same time. Example
