Description

Technical Field

[0001] This utility model relates to the field of scarf production technology, specifically to scarf anti-shrinkage finishing equipment. Background Technology

[0002] A scarf is a strip of fabric used for neck warmth, decoration, or protection, typically made of wool, cotton, silk, or synthetic fibers. It can be worn in various ways, providing warmth in cold weather or serving as a stylish accessory to enhance one's overall look, suitable for various occasions and seasons. To prevent scarves from shrinking when wet, an anti-shrinkage treatment is required during the scarf production process, necessitating the use of scarf anti-shrinkage finishing equipment. Existing scarf anti-shrinkage finishing equipment often consists of multiple sets of rollers. The soaked scarf first passes through two rollers to squeeze out excess water, and then passes through two sets of rollers with different speeds. During this process, the faster-speed roller pulls the scarf forward. The slow-moving set of rollers restricts the forward movement of the scarf, creating a pulling force between the two sets of rollers to eliminate stress in the internal fibers. This, combined with subsequent drying and shaping, helps prevent shrinkage. Traditional scarf shrinkage prevention equipment uses two rollers to squeeze out excess water from the soaked scarf, resulting in a short dwell time between the two rollers and incomplete dehydration, affecting subsequent stretching. Using only two sets of rollers with different speeds for stretching results in a short stretching stroke and requires slow feeding, impacting the efficiency of the shrinkage prevention process. Therefore, we propose a scarf shrinkage prevention equipment. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a scarf anti-shrinkage finishing device. The device can quickly and evenly squeeze out excess water from inside the scarf by the mutual squeezing of three extrusion rollers. It also adds three movable stretching rollers. By moving the stretching rollers up and down in conjunction with the driving of two sets of drive rollers, the scarf will undergo multiple reversals and be stretched more evenly. The movable stretching rollers also improve the stretching effect of the scarf and increase the feeding speed of the scarf, thereby improving the efficiency of the scarf anti-shrinkage work and effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a scarf anti-shrinkage finishing device, including a stretching seat, a water immersion mechanism, and a stretching mechanism;

[0005] The stretching seat has a water immersion seat placed behind it, and a water immersion tank is opened inside the rear of the water immersion seat;

[0006] The immersion mechanism includes a mounting frame, mounting columns, mounting blocks, tension springs, and squeeze rollers. The mounting frame is located in the middle of the front side inside the immersion seat. The mounting columns are located on the left and right sides of the outer surface of the mounting frame. The mounting blocks are slidably connected to the outer surface of the mounting columns. Tension springs are provided between the side of the mounting block away from the middle of the mounting frame and the outer end of the mounting column. The tension springs are sleeved on the outer surface of the mounting columns. Squeeze rollers are rotatably connected between two horizontally adjacent mounting blocks, providing a basis for the rapid dehydration of the immersion scarf.

[0007] Stretching mechanism: It is located inside the stretching seat. Through the mutual squeezing of three extrusion rollers, excess water inside the scarf can be squeezed out quickly and evenly. Three movable stretching rollers are also added. Through the up and down movement of the stretching rollers and the drive of two sets of drive rollers, the scarf will undergo multiple reversals and be stretched more evenly. The movable stretching rollers also improve the stretching effect of the scarf and increase the feeding speed of the scarf, thereby improving the efficiency of the scarf anti-shrinkage work.

[0008] Furthermore, the immersion mechanism also includes guide rollers and immersion rollers. The guide rollers are rotatably connected to the upper part of the immersion seat, and the immersion rollers are rotatably connected to the middle of the immersion tank. The two rear guide rollers are installed in conjunction with the immersion rollers, providing a basis for the automatic immersion of the scarf.

[0009] Furthermore, the stretching mechanism includes a connecting frame, a slider, a stretching roller, and a bidirectional lead screw. Slide grooves are provided in the middle of the left and right walls of the stretching seat. The connecting frame is slidably connected to the lower end of the slide groove, and the slider is slidably connected to the upper end of the slide groove. A stretching roller is rotatably connected between the connecting frame and the slider. The bidirectional lead screw is rotatably connected to the middle of the left slide groove. The middle of the connecting frame and the slider on the left side are threadedly connected to the outer surface of the bidirectional lead screw, increasing the scarf stretching stroke while ensuring the scarf feeding speed.

[0010] Furthermore, the stretching mechanism also includes a motor, which is located at the middle of the upper left side of the stretching seat. The input end of the motor is electrically connected to the output end of the microcontroller, and the lower end of the output end of the motor is fixedly connected to the upper end of the bidirectional lead screw, providing a stable driving effect for the movement of the stretching roller.

[0011] Furthermore, it also includes drive rollers and gears. The drive rollers are rotatably connected to the middle of the front and rear sides inside the stretching seat, and the gears are all located at the left end of the drive rollers. Two vertically adjacent gears are meshed together. The two drive rollers located on the rear side are installed in conjunction with the guide roller on the front side, providing a basis for stable feeding of the scarf.

[0012] Furthermore, it also includes a second motor, which is respectively located at the front and rear ends of the middle right side of the stretching seat. The input end of the second motor is electrically connected to the output end of the microcontroller, and the left end of the output shaft of the second motor is fixedly connected to the right end of the horizontally adjacent drive roller, so as to provide a stable driving effect for the stable feeding of the scarf.

[0013] Furthermore, it also includes a microcontroller, which is located in the middle right side of the stretching seat. The input terminal of the microcontroller is electrically connected to an external power supply, providing a basis for the scarf's anti-shrinkage function.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This scarf anti-shrinkage finishing device has the following advantages:

[0015] 1. When the scarf is driven by the drive roller through the extrusion roller, the tension of the scarf itself, the extrusion force formed by the contact between the extrusion roller surface and the scarf surface, and the pulling force of the tension spring itself pulling the extrusion roller outward work together to quickly and evenly squeeze out excess water from inside the scarf, avoiding the problem of insufficient water squeezing affecting the subsequent stretching of the scarf.

[0016] 2. The scarf is stretched by the up-and-down movement of the stretching roller in conjunction with the drive of two sets of drive rollers. The scarf will pass through different stretching rollers multiple times and be stretched more evenly. At the same time, when the stretching roller moves outward synchronously, there will be an outward stretching effect on the scarf. This can completely eliminate the internal stress of the scarf in a shorter stroke. The feeding speed of the scarf can be accelerated in this process to improve the efficiency of the scarf anti-shrinkage work. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-7 This embodiment provides a technical solution: a scarf anti-shrinkage finishing device, including a stretching seat 1, a water immersion mechanism 4, and a stretching mechanism 5;

[0027] Stretching seat 1: A water soaking seat 2 is placed behind it. An external hot press can be placed in front of the stretching seat 1. The external hot press is a common hot press roller type hot press, which is used for hot pressing and forming of the scarf after stretching. A water soaking tank 3 is opened on the rear side of the inside of the water soaking seat 2. The water soaking tank 3 is filled with clean water. It also includes a microcontroller 9. The microcontroller 9 is located in the middle right side of the stretching seat 1. The input end of the microcontroller 9 is electrically connected to an external power supply, which provides the basis for the anti-shrinkage work of the scarf.

[0028] The soaking mechanism 4 includes a mounting frame 41, mounting columns 42, mounting blocks 43, tension springs 44, and squeeze rollers 45. The mounting frame 41 is located in the middle of the front side inside the soaking base 2. The mounting columns 42 are respectively located on the left and right sides of the outer surface of the mounting frame 41. The mounting blocks 43 are slidably connected to the outer surface of the mounting columns 42. Tension springs 44 are provided between the side of the mounting block 43 away from the middle of the mounting frame 41 and the outer end of the mounting column 42. The tension springs 44 are sleeved on the outer surface of the mounting columns 42. Squeeze rollers 45 are rotatably connected between two horizontally adjacent mounting blocks 43, providing a basis for the rapid dehydration of the soaked scarf. The soaking mechanism 4 also includes guide rollers 46 and soaking rollers 47. The guide rollers 46 are rotatably connected to the upper part of the inside of the soaking base 2, and the soaking rollers 47 are rotatably connected to the middle of the inside of the soaking tank 3. The two rear guide rollers 46 are installed in conjunction with the soaking rollers 47, and the scarf can pass through the two rear guide rollers. The guide rollers 46 and immersion rollers 47 guide the scarves into the immersion tank 3 for immersion, providing a basis for the automatic immersion of the scarves. It also includes drive rollers 6 and gears 7. The drive rollers 6 are rotatably connected to the middle of the front and rear sides inside the stretching seat 1. The gears 7 are all located at the left end of the drive rollers 6. The two vertically adjacent gears 7 are meshed together. The two drive rollers 6 located at the rear are installed in cooperation with the guide rollers 46 at the front. The guide rollers 46 at the front can feed the dehydrated scarves between the two drive rollers 6 at the rear, which facilitates the feeding of the scarves before the stretching work and provides a basis for the stable feeding of the scarves. It also includes a second motor 8. The second motor 8 is located at the front and rear ends of the middle right side of the stretching seat 1. The input end of the second motor 8 is electrically connected to the output end of the single-chip microcomputer 9. The left end of the output shaft of the second motor 8 is fixedly connected to the right end of the horizontally adjacent drive roller 6, providing a stable driving effect for the stable feeding of the scarves.

[0029] The stretching mechanism 5 is located inside the stretching seat 1. It includes a connecting frame 51, a slider 52, a stretching roller 53, and a bidirectional lead screw 54. Slide grooves 10 are provided in the middle of the left and right walls of the stretching seat 1. The connecting frame 51 is slidably connected to the lower end of the slide groove 10, and the slider 52 is slidably connected to the upper end of the slide groove 10. The connecting frame 51 and slider 52 are slidably connected to the inner wall of the slide groove 10 through the limiting and guiding of the sliding column. The stretching roller 53 is rotatably connected between the connecting frame 51 and the slider 52. The bidirectional lead screw 54 is rotatably connected to the middle of the left slide groove 10. The middle of the connecting frame 51 and the slider 52 on the left side are threaded to the outer surface of the bidirectional lead screw 54. This increases the scarf stretching stroke and also improves the scarf's elasticity. The feeding speed of the scarf and the stretching mechanism 5 also include a motor 55. The motor 55 is located at the middle of the upper left side of the stretching base 1. The input end of the motor 55 is electrically connected to the output end of the microcontroller 9. The lower end of the output end of the motor 55 is fixedly connected to the upper end of the bidirectional lead screw 54, providing a stable driving effect for the movement of the stretching roller 53. The excess water inside the scarf can be squeezed out quickly and evenly through the mutual squeezing of the three squeezing rollers 45. Three movable stretching rollers 53 are also added. Through the up and down movement of the stretching rollers 53 and the driving of the two sets of drive rollers 6, the scarf will undergo multiple reversals and be stretched more evenly. The movable stretching rollers 53 also improve the stretching effect of the scarf and increase the feeding speed of the scarf, thereby improving the efficiency of the scarf anti-shrinkage work.

[0030] The working principle of the scarf anti-shrinkage finishing device provided by this utility model is as follows: Before performing the anti-shrinkage work, the scarf is placed inside the device. The scarf descends from above the rear guide roller 46, passes below the two soaking rollers 47, then ascends, passes above the middle guide roller 46, descends, ascends from below the rear squeeze roller 45, passes the surface of the middle squeeze roller 45, descends, passes below the front squeeze roller 45, ascends, passes above the front guide roller 46, and enters between the two rear drive rollers 6. Then, it descends below the lower rear stretch roller 53, ascends, passes above the upper stretch roller 53, descends, and then ascends from below the lower front stretch roller 53, passing between the two front drive rollers 6. Finally, the scarf is placed between the two hot press rollers of the external hot press. Then, the anti-shrinkage process begins. The microcontroller 9 controls the operation of two motors 8. The motors 8 drive the corresponding drive rollers 6 to rotate forward, and the corresponding gears 7 also rotate accordingly. Because the two vertically adjacent gears 7 are meshed, the two vertically adjacent drive rollers 6 rotate in opposite directions. The two drive rollers 6 will move the scarf forward while holding it. At this time, as the scarf moves, it is first guided by the two rear guide rollers 46 and the soaking roller 47 into the soaking tank 3. When the scarf exits the soaking tank 3 through the middle guide roller 46, it is already full of water. As the two rear drive rollers 6 continue to drive, the scarf before the squeezing roller 45 is pushed by the drive rollers 6. Pulling forward, the scarf behind the squeezing roller 45 moves slowly forward due to the resistance of the guide roller 46, the soaking roller 47, and the water inside the soaking tank 3. At this time, the scarf on the surface of the three squeezing rollers 45 will form a certain tension force, squeezing the three squeezing rollers 45 inward synchronously. The tension spring 44 is stretched by force. At this time, the tension force of the scarf itself, the squeezing force formed by the surface of the squeezing roller 45 and the surface of the scarf adhering to each other, and the pulling force of the tension spring 44 itself pulling the squeezing roller 45 outward work together to remove excess water from the scarf, realizing the rapid dehydration of the scarf. At the same time, the microcontroller 9 controls the motor 55 to operate. The output shaft of the motor 55 drives the bidirectional lead screw 54 to rotate forward. At this time, the upper and lower tension rollers 53 are in a separated state. As the bidirectional lead screw 54 rotates forward, the continuous The connecting frame 51 and slider 52 move inward synchronously, and the upper and lower stretching rollers 53 also move inward synchronously. The distance between the three stretching rollers 53 decreases, and the stroke of the wrapped scarf shortens. At this time, the microcontroller 9 controls motor 8 to work, so that the speed of the two sets of drive rollers 6 is synchronized proportionally to ensure that the scarf has enough time to eliminate internal stress. When the upper and lower stretching rollers 53 move inward to the appropriate position, the speed of the two sets of drive rollers 6 decreases to the normal speed. The microcontroller 9 controls motor 55 to reverse, and the bidirectional lead screw 54 also reverses accordingly. The upper and lower stretching rollers 53 move outward synchronously, and the distance between the three stretching rollers 53 increases, so the stroke of the wrapped scarf lengthens. At this time, the microcontroller 9 controls motor 8 to work again, so that the speed of the two sets of drive rollers 6 is accelerated proportionally.The scarf passes through different stretching rollers 53 multiple times, resulting in more even stretching. When the stretching rollers 53 move outward synchronously, they also exert an outward pulling effect on the scarf. After exiting the stretching seat 1, the scarf is hot-pressed and shaped by external hot-pressing rollers, completing the anti-shrinkage process. During this process, let's designate a point on the scarf as point a. At normal speed, point a enters the stretching seat 1 from between a set of drive rollers 6 on the rear side and exits from between a set of drive rollers 6 on the front side. The travel distance is designated as b. The stretching of the scarf through this travel distance b completely eliminates the stress within the fibers. When the upper and lower stretching rollers 53 move inward synchronously, the distance between the three stretching rollers 53 decreases, and the travel distance of the scarf wrapped around the surfaces of the three stretching rollers 53 also shortens. The travel distance from point a from entering to exiting the stretching seat 1 becomes shorter, and the pulling force of the stretching rollers 53 on the scarf gradually increases as the stretching rollers 53 move inward synchronously. The distance between the two sets of drive rollers 6 decreases, so the travel distance from point a from entering the stretching seat 1 to exiting the stretching seat 1 is equal to b, and the time taken is also equal to the time taken by the drive rollers 6 at normal speed. This ensures that the internal stress of the scarf is completely eliminated. When the upper and lower stretching rollers 53 move outward synchronously, the distance between the three stretching rollers 53 increases, and the travel distance of the scarf wrapped around the surface of the three stretching rollers 53 also increases. The travel distance from point a from entering the stretching seat 1 to exiting the stretching seat 1 becomes longer. The synchronously moving stretching rollers 53 can exert an outward pulling force on the scarf, and can completely eliminate the internal stress of the scarf with a travel distance less than b. To improve the efficiency of the scarf anti-shrinkage work, the two sets of drive rollers 6 are accelerated, so that the travel distance from point a from entering the stretching seat 1 to exiting the stretching seat 1 is less than b, and the time taken is greater than the time taken by the drive rollers 6 at normal speed, thus improving the efficiency of the scarf anti-shrinkage work.

[0031] It is worth noting that the microcontroller 9 disclosed in the above embodiments is an STM32G431RBT6 microcontroller, motor 55 is a 1FT7136-5AC71-1MA1 motor, and motor 8 is a SIMOTICS M motor. The microcontroller 9 controls the operation of motor 55 and motor 8 using methods commonly used in the prior art.
