Description

Technical Field

[0001] This utility model belongs to the technical field of carding machines, and specifically relates to a double-feed roller mechanism for carding machines. Background Technology

[0002] Carding machines are used to process cotton fibers and chemical fibers. They belong to textile machinery. The working principle of a carding machine is to open, comb, and remove impurities from the cotton (fiber) rolls sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box. This process transforms all the curled and lumpy cotton loops into basically straight single fibers. In this process, broken seeds, impurities, and short fibers left over from the cleaning process are removed. The cotton is then integrated into slivers of a certain specification and stored in cotton bolls for use in the drawing process.

[0003] When the carding machine's feed roller is working, some cotton from the cotton sliver may become entangled on it. This entanglement causes unstable roller speed, disrupts the stability of the drafting process, and leads to problems such as unevenness and coarseness in the cotton sliver. Current technology requires operators to stop the machine and separate the cotton sliver from the feed roller when this happens. This not only increases the workload of the operators but also affects the efficiency of the carding machine. Therefore, designing a dual-feed roller mechanism for the carding machine is a problem we need to solve. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-feed roller mechanism for a carding machine.

[0005] To achieve the above objectives, this utility model provides a dual-feed roller mechanism for a carding machine, comprising a carding machine body, a front feed roller and a rear feed roller rotatably connected inside the carding machine body, the front feed roller and the rear feed roller being spaced 3.5 cm apart, pressure arms provided on the top of the front feed roller and the rear feed roller, a motor fixedly installed on one side of the carding machine body, the output shaft of the motor fixedly connected to one end of the front feed roller; a feed roller mechanism, which assists the carding machine body and the front feed roller in improving the carding quality of the cotton layer, the feed roller mechanism being connected to the front feed roller and the rear feed roller; and a cleaning component, which is used to clean the front feed roller and the rear feed roller, the cleaning component being connected to the carding machine body, the front feed roller and the rear feed roller.

[0006] In the above technical solution, the feeding roller mechanism further includes a first sprocket fixedly connected to one end of the front feeding roller and a second sprocket fixedly connected to one end of the rear feeding roller. The outer walls of the first sprocket and the second sprocket are meshed with a chain. A protective shell is rotatably connected to the side of the first sprocket and the second sprocket away from the front feeding roller and the rear feeding roller. The protective shell is fixedly installed on one side of the carding machine body.

[0007] In the above technical solution, the cleaning component further includes two fixed rods fixedly connected inside the protective shell, and the outer walls of the two fixed rods are rotatably connected to sleeve rods, which are rotatably connected inside the carding machine body.

[0008] In the above technical solution, a top block is fixedly connected to the outer wall of the fixing rod, an elastic band is sleeved on the outer wall of the top block, and multiple scrapers are fixedly connected to the outer wall of the elastic band, with the multiple scrapers slidably connected inside the sleeve rod.

[0009] In the above technical solution, the outer walls of the two sleeve rods are tensioned with a synchronous belt, and a third sprocket is fixedly connected to the outer wall of one of the sleeve rods, the third sprocket being engaged inside the chain.

[0010] In the above technical solution, a pressure bar is further provided at the top of the chain, and the pressure bar is rotatably connected to the inside of the protective shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a cleaning component, the cotton layer that initially wraps around the front or rear feed roller can be scraped off, preventing the cotton layer from wrapping around the front or rear feed roller, which can cause unstable rotation speed, disrupt the stability of the drafting process, and cause problems such as unevenness and coarseness of the cotton layer. In addition, the cotton layer on the scraper can be removed afterward to prevent the cotton layer from wrapping around the sleeve rod and the outer wall of the scraper, thus avoiding the situation where the sleeve rod and the scraper work normally. By setting up a cotton feeding roller mechanism, a speed ratio of 1.07 is achieved between the front and rear cotton feeding rollers. This generates a certain stretching and pulling effect between the two rollers, improving the straightening and parallelism of the fibers in the cotton layer. This makes the cotton layer enter the carding area more evenly, which is beneficial to improving the carding quality. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 2 The diagram illustrates a dual-feed roller mechanism for a carding machine, comprising a carding machine body 1. A front feed roller 2 and a rear feed roller 3 are rotatably connected inside the carding machine body 1. The arrangement of the front and rear feed rollers allows for better control of the cotton layer feeding speed and amount, enabling a light-weight input of the cotton lap and a heavy-weight output of the cotton sliver between the two rollers. The front and rear feed rollers 2 and 3 are spaced 3.5 cm apart. A pressure arm 4 is located at the top of both the front and rear feed rollers 2 and 3, allowing them to share a single pressure arm 4 for pressure application. The configuration ensures that the pressure of the front feed roller 2 and the rear feed roller 3 remains consistent. A motor 5 is fixedly installed on one side of the carding machine body 1, and the output shaft of the motor 5 is fixedly connected to one end of the front feed roller 2. The feed roller mechanism assists the carding machine body 1 and the front feed roller 2 in improving the carding quality of the cotton layer. The feed roller structure is connected to the front feed roller 2 and the rear feed roller 3. The cleaning component is used to clean the front feed roller 2 and the rear feed roller 3. The cleaning component is connected to the carding machine body 1, the front feed roller 2, and the rear feed roller 3.

[0016] like Figure 3 As shown, the cotton feeding roller mechanism includes a first sprocket 6 fixedly connected to one end of the front cotton feeding roller 2 and a second sprocket 7 fixedly connected to one end of the rear cotton feeding roller 3. A chain 8 meshes with the outer walls of the first sprocket 6 and the second sprocket 7. By setting the first sprocket 6 to be a 15-tooth sprocket and the second sprocket 7 to be a 16-tooth sprocket, a speed ratio of 1.07 is achieved between the front cotton feeding roller 2 and the rear cotton feeding roller 3. The cotton layer generates a certain stretching and pulling effect between the two rollers, improving the straightening and parallelism of the fibers in the cotton layer, making the cotton layer enter the carding area more evenly, which is beneficial to improving the carding quality. A protective shell 9 is rotatably connected to the side of the first sprocket 6 and the second sprocket 7 away from the front cotton feeding roller 2 and the rear cotton feeding roller 3. The protective shell 9 is fixedly installed on one side of the carding machine body 1.

[0017] like Figures 3 to 4 As shown, the cleaning assembly includes two fixed rods 10 fixedly connected inside the protective shell 9. Each of the two fixed rods 10 has a sleeve rod 11 rotatably connected to its outer wall. The sleeve rod 11 is rotatably connected inside the carding machine body 1. A top block 12 is fixedly connected to the outer wall of the fixed rod 10. An elastic band 13 is sleeved on the outer wall of the top block 12. Multiple scrapers 14 are fixedly connected to the outer wall of the elastic band 13. The multiple scrapers 14 are slidably connected inside the sleeve rod 11. A synchronous belt 15 is tensioned on the outer walls of the two sleeve rods 11. A third sprocket 16 is fixedly connected to the outer wall of one of the sleeve rods 11. The third sprocket 16 meshes inside the chain 8. A pressure rod 17 is provided at the top of the chain 8. The pressure rod 17 is rotatably connected inside the protective shell 9. By setting the pressure rod 17, the chain 8 can be limited to prevent it from jumping during rotation, thus affecting the rotation of the third sprocket 16.

[0018] Working principle: When the operator starts the carding machine, the motor 5 drives the front feed roller 2 to rotate. The front feed roller 2 drives the rear feed roller 3 to rotate via the first sprocket 6, chain 8, and second sprocket 7. The rotation of the front feed roller 2 and the rear feed roller 3 combs the cotton layer. This causes the chain 8 to drive the third sprocket 16 to rotate, which in turn drives one of the sleeve rods 11 to rotate. The sleeve rod 11 drives the other sleeve rod 11 to rotate via the timing belt 15. The rotation of the sleeve rod 11 drives the scraper 14 to rotate as well. The scraper 14 drives the elastic band 13 to rotate on the outer wall of the top block 12. When the scraper 14 rotates to the position where the sleeve rod 11 is aligned with the corresponding front feed roller 12, the scraper 14 rotates. When feeding between the front and rear feed rollers 2 and 3, the scraper 14 is pushed by the top block 12 to fit against the outer wall of the corresponding front or rear feed roller 2 or 3, so that the scraper 14 scrapes off the cotton layer that begins to wrap around the outer wall of the front or rear feed roller 3. As rotation continues, the scraper 14 will continuously rotate to the corresponding front or rear feed roller 2 or 3 to scrape off the cotton layer that begins to wrap around the front or rear feed roller 3, so as to avoid the cotton layer from wrapping around the front or rear feed roller 3, which would cause unstable rotation speed, damage the stability of the drafting process, and cause problems such as coarse and fine details and uneven yarn in the cotton layer. Furthermore, as the scraper 14 rotates to the bottom of the sleeve rod 11, the scraper 14 is no longer pushed by the top block 12. Under the contraction force of the elastic band 13, the scraper 14 returns to its original position and enters the interior of the sleeve rod 11. At this time, the cotton layer scraped off from the corresponding front cotton roller 2 or rear cotton roller 3 by the sleeve rod 11 will be blocked and detached by the sleeve rod 11, so that the cotton layer will not stick to the scraper 14. This avoids the situation where the cotton layer is wrapped around the outer wall of the sleeve rod 11 and the scraper 14, which would affect the normal operation of the sleeve rod 11 and the scraper 14.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
