Description

Technical Field

[0001] This utility model relates to the technical field of fabric collection mechanisms, and in particular to a fabric collection mechanism for a circular knitting machine. Background Technology

[0002] In the textile industry, the circular knitting machine is a key piece of equipment for producing knitted fabrics. Its technological development is closely related to the fabric collection process. In the early days, the fabric collection of the circular knitting machine mainly relied on manual operation. Workers had to pay attention to the fabric output at all times, manually pull the fabric and perform simple folding or winding, which was inefficient and labor-intensive. With the advancement of technology, some basic pulling and winding mechanisms gradually emerged. For example, by using a simple combination of mechanical rollers, the friction between the rollers is used to pull the fabric out of the knitting area of ​​the knitting machine. However, such mechanisms have many problems.

[0003] On the one hand, in terms of ensuring fabric flatness, traditional equipment lacks effective smoothing methods. During the collection process, the fabric is prone to shrinkage in the width direction due to frequent changes in its own tension and conveying direction, resulting in wrinkles, water ripples, or even curling edges, which seriously affects the quality of the fabric and increases the difficulty and cost of subsequent finishing processes.

[0004] On the other hand, collection efficiency urgently needs to be improved. For example, in the early fabric winding mechanism, after a certain amount of fabric was wound, it was necessary to manually cut the fabric and remove the winding shaft at the bottom of the equipment with limited space. The operation was inconvenient, not only time-consuming and labor-intensive, but also affected the overall production rhythm, making it difficult to meet the needs of large-scale and high-efficiency production. In addition, traditional equipment is seriously lacking in automation and has poor coordination between various links, making it difficult to adapt to the requirements of modern textile production for efficient, stable and precise operation. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a fabric collection mechanism for a circular knitting machine that can solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fabric collection mechanism for a circular knitting machine, comprising a knitting machine, a base plate being provided below the knitting machine, and a first fixing plate being fixedly connected to the left and right sides of the front end of the base plate;

[0007] Two traction shafts are rotatably connected between the first fixed plates, and two second fixed plates are fixedly connected to the two sides of the middle position of the base plate. Two traction shafts are rotatably connected between the second fixed plates.

[0008] The rear end of the second fixed plate is provided with a sliding groove, and a limiting plate is fixedly connected to the second fixed plate. A threaded rod is rotatably connected between the limiting plate and the base plate in the sliding groove. A slider is threadedly connected to the threaded rod. A micro motor is fixedly connected to the second fixed plate, and the output end of the micro motor is fixedly connected to the threaded rod.

[0009] A cutting blade is fixedly connected to the slider, and a base blade is fixedly connected to the rear end of the second fixed plate below the cutting blade; a third fixed plate is fixedly connected to the rear end of the second fixed plate on both sides of the base, a baffle is fixedly connected to the upper and lower parts of the third fixed plate, a spring is fixedly connected to the inner side of the baffle, a flat plate is fixedly connected to the spring, and a rubber wheel is rotatably connected in the flat plate.

[0010] A fourth fixing plate is fixedly connected to one side of the rear end of the base. A drive motor is fixedly connected to the outer side of the fourth fixing plate. A turntable is fixedly connected to the output end of the drive motor. A curling frame is fixedly connected to the turntable.

[0011] Preferably, the surface of the traction shaft is provided with anti-slip texture.

[0012] Preferably, bearing seats are provided at both ends of the traction shaft, and the bearing seats are fixedly connected to the second fixing plate.

[0013] Preferably, the micro motor is fixed to the second fixing plate by bolts.

[0014] Preferably, the cutting blade has a replaceable blade structure.

[0015] Preferably, the upper surface of the tool holder is provided with a wear-resistant coating.

[0016] Preferably, the surface of the rubber wheel is provided with elastic protrusions.

[0017] Preferably, the output shaft of the drive motor is connected to the turntable via a coupling.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In the fabric collection mechanism of this circular knitting machine, when the fabric is conveyed to the smoothing component area, the spring fixed inside the baffle on the third fixed plate is in a compressed state. Its inward elastic force pushes the smoothing plate, so that the rubber wheel on the smoothing plate is tightly attached to both sides of the fabric. As the fabric moves with the traction shaft, the rubber wheel generates friction with the fabric surface. At the same time, the elastic force of the spring continues to act. The two work together to pull and flatten the fabric, effectively eliminating wrinkles on the fabric surface and ensuring that the fabric is flat.

[0020] 2. The fabric collection mechanism of this circular knitting machine starts a micro motor when a certain amount of fabric is collected on the crimping frame. Its output end drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the slider, and the slider is limited by the slide groove and can only move along the direction of the slide groove, the slider moves linearly along the slide groove on the second fixed plate during the rotation of the threaded rod. The slider drives the cutting blade fixed on it to move synchronously. The cutting blade gradually approaches the base blade. When the two come into contact, the fabric is cut and separated. After the cutting is completed, the collected fabric on the crimping frame can be pulled out to make room for a new round of crimping and collection work, thereby realizing the cycle of fabric collection work.

[0031] Please see Figure 1-4 This utility model provides a technical solution: a fabric collection mechanism for a circular knitting machine, including a knitting machine 1, which is an existing device, a base plate 2 is provided below the knitting machine 1, and a first fixing plate 3 is fixedly connected to the left and right sides of the front end of the base plate 2.

[0032] Two traction shafts 4 are rotatably connected between the first fixed plates 3, and two second fixed plates 5 are fixedly connected on both sides of the middle position of the base plate 2. Two traction shafts 9 are rotatably connected between the second fixed plates 5.

[0033] After the knitting machine 1 operates normally and weaves the fabric, the fabric hangs down to the area of ​​the bottom plate 2 below by its own weight. The two traction shafts 4 start to rotate under the action of the fabric's weight and friction, pulling the fabric down smoothly from the knitting machine 1 and conveying it to the position of the two traction shafts 9. The traction shafts 9 continue to take over and further pull and convey the fabric backward.

[0034] The rear end of the second fixed plate 5 is provided with a sliding groove 6. A limiting plate 10 is fixedly connected to the second fixed plate 5. A threaded rod 8 is rotatably connected between the limiting plate 10 and the bottom plate 2 in the sliding groove 6. A slider 7 is threadedly connected to the threaded rod 8. A micro motor 11 is fixedly connected to the second fixed plate 5. The output end of the micro motor 11 is fixedly connected to the threaded rod 8.

[0035] A cutting blade 12 is fixedly connected to the slider 7, and a base blade 13 is fixedly connected to the lower part of the cutting blade 12 at the rear end of the second fixed plate 5.

[0036] When the fabric collected on the curling frame 22 reaches a certain amount, the micro motor 11 starts, and its output end drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the slider 7, and the slider 7 is limited by the slide groove 6 and can only move along the direction of the slide groove 6, during the rotation of the threaded rod 8, the slider 7 moves linearly along the slide groove 6 on the second fixed plate 5. The slider 7 drives the cutting blade 12 fixed on it to move synchronously. The cutting blade 12 gradually approaches the base blade 13. When the two come into contact, the fabric is cut and separated.

[0037] The rear ends of the second fixing plates 5 on both sides of the base plate 2 are fixedly connected to the third fixing plate 14. The upper and lower sides of the third fixing plate 14 are fixedly connected to the baffle 15. The inner side of the baffle 15 is fixedly connected to the spring 16. The flat plate 17 is fixedly connected to the spring 16. The flat plate 17 is rotatably connected to the rubber wheel 18.

[0038] When the fabric is conveyed to the smoothing component area, the spring 16 fixed inside the baffle 15 on the third fixed plate 14 is in a compressed state. Its inward elastic force pushes the smoothing plate 17, so that the rubber wheel 18 on the smoothing plate 17 fits tightly against both sides of the fabric. As the fabric moves with the traction shaft 9, the rubber wheel 18 generates friction with the fabric surface. At the same time, the elastic force of the spring 16 continues to act. The two work together to pull and flatten the fabric, effectively eliminating wrinkles on the fabric surface and ensuring that the fabric is flat.

[0039] A fourth fixing plate 23 is fixedly connected to one side of the rear end of the base plate 2. A drive motor 19 is fixedly connected to the outer side of the fourth fixing plate 23. A turntable 21 is fixedly connected to the output end of the drive motor 19. A curling frame 22 is fixedly connected to the turntable 21. A support column 20 is fixedly connected to the bottom of the drive motor 19.

[0040] When the drive motor 19 starts, its output drives the turntable 21 to rotate. The curling frame 22 fixed on the turntable 21 rotates accordingly. Under the combined action of the continuous traction of the traction shaft 9 and the rotation of the curling frame 22, the flat fabric gradually winds around the curling frame 22, completing the curling and collection of the fabric.

[0041] Working principle: After the knitting machine 1 knits the fabric normally, the fabric hangs down to the bottom plate 2 area below by its own weight. The two traction shafts 4 start to rotate under the action of the fabric's weight and friction, pulling the fabric down smoothly from the knitting machine 1 and conveying it to the position of the two traction shafts 9. The traction shafts 9 continue to take over and further pull and convey the fabric backward.

[0042] When the fabric is conveyed to the smoothing component area, the spring 16 fixed inside the baffle 15 on the third fixed plate 14 is in a compressed state. Its inward elastic force pushes the smoothing plate 17, so that the rubber wheel 18 on the smoothing plate 17 fits tightly against both sides of the fabric. As the fabric moves with the traction shaft 9, the rubber wheel 18 generates friction with the fabric surface. At the same time, the elastic force of the spring 16 continues to act. The two work together to pull and flatten the fabric, effectively eliminating wrinkles on the fabric surface and ensuring that the fabric is flat.

[0043] Subsequently, the drive motor 19 starts, and its output drives the turntable 21 to rotate. The curling frame 22 fixed on the turntable 21 rotates accordingly. Under the combined action of the continuous traction of the traction shaft 9 and the rotation of the curling frame 22, the flat fabric gradually wraps around the curling frame 22, completing the curling and collection of the fabric.

[0044] When the fabric collected on the curling frame 22 reaches a certain amount, the micro motor 11 starts, and its output end drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the slider 7, and the slider 7 is limited by the slide groove 6 and can only move along the direction of the slide groove 6, during the rotation of the threaded rod 8, the slider 7 moves linearly along the slide groove 6 on the second fixed plate 5. The slider 7 drives the cutting blade 12 fixed on it to move synchronously. The cutting blade 12 gradually approaches the base blade 13. When the two come into contact, the fabric is cut and separated. After the cutting is completed, the collected fabric on the curling frame 22 can be pulled out to make room for a new round of curling and collecting work, thereby realizing the cycle of fabric collection work.

[0045] The fabric collection mechanism of this circular knitting machine has many significant advantages. In terms of working efficiency, the pull shaft 4 and the traction shaft 9 work together to continuously and stably pull and transport the fabric from the knitting machine 1. With the help of the drive motor 19 to drive the crimping frame 22 to quickly crimp and collect the fabric, the fabric collection time is greatly shortened. Moreover, the cutting process is carried out after the crimping is completed. Once the cutting is completed, the fabric can be pulled out to start a new round of collection, achieving efficient circulation, reducing downtime and waiting time, and improving overall production efficiency.

[0046] In terms of fabric quality assurance, the design of spring 16 and rubber wheel 18 in the flat panel 17 component is particularly critical. The elasticity provided by spring 16 makes rubber wheel 18 fit tightly against both sides of the fabric. During the movement of the fabric, friction pulls it flat, effectively eliminating wrinkles, ensuring the fabric is flat, improving the quality of finished fabric products, and reducing the defect rate.

[0047] In terms of ease of operation and practicality, the various components of the mechanism have clear division of labor and a high degree of automation. The micro motor 11 drives the cutting blade 12 to make precise cuts without the need for manual operation, thus reducing labor intensity. At the same time, the equipment has a compact structure, with each component installed on the base plate 2, occupying little space. It is compatible with a variety of circular knitting machines, making it easy to install and maintain, and effectively saving manpower and material costs.
