Description

Technical Field

[0001] This application relates to the field of carding machine technology, specifically a carding machine for recycled cotton yarn. Background Technology

[0002] Cotton yarn is yarn made from cotton fibers through spinning processes. After being plied, it is called cotton thread. During the processing of cotton yarn, a carding machine is usually used to open and comb it.

[0003] An existing patent (publication number: CN219385433U) discloses a cotton yarn carding machine, including: a machine box and a machine base. The machine base is connected to the bottom of the machine box. A connecting rod is installed on the upper left side inside the machine box. The lower end of the connecting rod is connected to a main water pipe. Multiple atomizing nozzles are installed on the lower surface of the main water pipe. A carding roller is installed in the middle inside the machine box. Multiple carding teeth are installed on the outer side of the carding roller. A drying fan is installed on the upper right side of the upper surface of the machine box and on the upper right side inside the machine base. Compared with the prior art, this utility model has the following beneficial effects: by setting the main water pipe and multiple atomizing nozzles, water can be sprayed on the surface of the cotton yarn before carding to prevent static electricity from being generated in the cotton yarn during the carding process. By setting the carding roller, drive motor, carding teeth, drying fan and electric heating grid, the cotton yarn can be carded. After the carding process is completed, the drying fan can dry the cotton yarn through the electric heating grid.

[0004] The aforementioned carding machine, by setting up a main water pipe and multiple atomizing nozzles, can spray water on the surface of the cotton yarn before carding to prevent static electricity from being generated during the carding process. However, although it can dry the cotton yarn afterward using a drying fan, when moisture penetrates into the inside of the cotton yarn, the drying fan may not be able to dry the cotton yarn completely, affecting the storage of the cotton yarn. Secondly, during the carding process, some cotton yarn is prone to gradually getting tangled on the carding teeth of the carding roller, affecting the carding effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a carding machine for recycled cotton yarn, which has advantages such as anti-tangling and anti-static properties, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a carding machine for recycled cotton yarn, including a base plate, two support plates fixedly connected to the upper surface of the base plate, a carding shaft rotatably connected between the two support plates, carding rollers fixedly connected to the outer surfaces of the two carding shafts, and a set of carding needles fixedly connected to the outer surface of each carding roller, with the two sets of carding needles arranged in an alternating pattern.

[0007] Two symmetrically arranged cleaning blocks are fixedly connected between the two support plates. The two cleaning blocks are located on the outside of the two carding rollers respectively. The side of the two cleaning blocks that are close to each other is set as an arc shape adapted to the carding roller and in contact with the outer surface of the carding roller. A set of through cleaning grooves is opened on the front of the two cleaning blocks. The inner top wall of the uppermost set of cleaning grooves and the inner bottom wall of the lowermost set of cleaning grooves are both provided with impurity suction grooves.

[0008] The above solution effectively removes lint and dust from the surface of the carding needles during the carding process. The design of the cleaning block, combined with the dust collection device, generates strong suction to ensure that lint and dust are collected in a timely manner, avoiding interference from impurities on the carding effect and improving the purity and quality of the cotton yarn. By setting antistatic plates with ion fans at the front and rear ends of the support plate, static electricity on the carding needles and cotton yarn can be effectively eliminated, reducing problems such as cotton yarn entanglement and carding needle adhesion caused by static electricity. This not only improves carding efficiency but also ensures the stability and continuity of the carding process. The rounded corners at both ends of the cleaning trough and the matching of the cleaning trough width with the diameter of the carding needles allow the carding needles to smoothly enter the cleaning trough during rotation, achieving a good scraping effect with the cleaning block.

[0009] Furthermore, the upper surface of the uppermost cleaning block is fixedly connected to a first suction pipe, and the bottom of the lowermost cleaning block is fixedly connected to a second suction pipe. The second suction pipe is fixedly connected to the first suction pipe, and the other end of the first suction pipe is connected to an external vacuuming device.

[0010] The above scheme and setup can generate suction to collect hair and dust.

[0011] Furthermore, both of the two support plates are fixedly connected to downwardly inclined antistatic plates at their front and rear ends, and an ion fan is installed inside the antistatic plates.

[0012] The above method, through the setting of the ion fan, can remove static electricity from the carding needles and reduce their adhesion.

[0013] Furthermore, the edges at both ends of each of the cleaning tanks are rounded.

[0014] The above scheme and settings facilitate the entry of the carding needles into the cleaning tank during the rotation of the carding needles.

[0015] Furthermore, the width of the cleaning groove is equal to the diameter of the comb needle.

[0016] The above scheme and settings can achieve the scraping effect between the cleaning tank and the comb needles.

[0017] Furthermore, both of the two support plates are fixedly connected to workbenches at their front and rear ends.

[0018] The above solution, through the setting of the workbench, can achieve the purpose of supporting materials.

[0019] Furthermore, two motors are installed on one side of the leftmost support plate, and the output end of each motor is fixedly connected to one end of the carding shaft adjacent to it via a coupling.

[0020] The above scheme and settings can provide power for the rotation of the carding shaft.

[0021] Furthermore, the surfaces of the two cleaning blocks that are close to each other and the outer surfaces of the two carding rollers are all polished.

[0022] The above solution and settings can reduce the frictional resistance when the two come into contact, thereby increasing their service life.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This carding machine for recycled cotton yarn effectively removes lint and dust from the surface of the carding needles during the carding process. The design of the cleaning block, combined with the dust collection device, generates strong suction to ensure that lint and dust are collected in a timely manner, avoiding interference from impurities on the carding effect and improving the purity and quality of the cotton yarn. By setting antistatic plates with ion fans at the front and rear ends of the support plate, static electricity on the carding needles and cotton yarn can be effectively eliminated, reducing problems such as cotton yarn entanglement and carding needle adhesion caused by static electricity. This not only improves carding efficiency but also ensures the stability and continuity of the carding process. The rounded corners at both ends of the cleaning trough and the matching of the cleaning trough width with the diameter of the carding needles allow the carding needles to smoothly enter the cleaning trough during rotation, achieving a good scraping effect with the cleaning block.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The carding machine for recycled cotton yarn in this embodiment includes a base plate 1. Two support plates 2 are fixedly connected to the upper surface of the base plate 1. A carding shaft 3 is rotatably connected between the two support plates 2. Carding rollers 4 are fixedly connected to the outer surfaces of the two carding shafts 3. A set of carding needles 5 is fixedly connected to the outer surface of each carding roller 4. The two sets of carding needles 5 are arranged in an alternating manner. An antistatic plate 11 with a downward inclination is fixedly connected to the front and rear ends of the two support plates 2. An ion fan 12 is installed inside the antistatic plate 11. Through the setting of the ion fan 12, the carding needles 5 can be destaticated, reducing their adhesion.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The front and rear ends of the two support plates 2 are fixedly connected to workbenches 13. The workbenches 13 can support the material. Two symmetrically arranged cleaning blocks 6 are fixedly connected between the two support plates 2. The two cleaning blocks 6 are located on the outside of the two carding rollers 4 respectively. The side of the two cleaning blocks 6 that is close to each other is set as an arc shape that is adapted to the carding rollers 4 and contacts the outer surface of the carding rollers 4. A set of through cleaning grooves 7 are opened on the front of the two cleaning blocks 6. The inner top wall of the uppermost set of cleaning grooves 7 and the inner bottom wall of the lowermost set of cleaning grooves 7 are provided with suction grooves 8. By rotating the cleaning blocks 6, the carding needles 5 can be driven to move in a circular motion. The carding needles 5 pass through the cleaning grooves 7, which can clean the impurities on their surface. The impurities are sucked into the cleaning blocks 6 from the suction grooves 8 by suction.

[0034] Please see Figure 1 , Figure 2 and Figure 3The width of the cleaning groove 7 is equal to the diameter of the comb needle 5. Through the above setting, the cleaning groove 7 and the comb needle 5 can be scraped. The two ends of each cleaning groove 7 are rounded. Through the above setting, the comb needle 5 can easily enter the cleaning groove 7 during the rotation of the comb needle 5. The upper surface of the uppermost cleaning block 6 is fixedly connected to the first suction pipe 9, and the bottom of the lowermost cleaning block 6 is fixedly connected to the second suction pipe 10. The second suction pipe 10 is fixedly connected to the first suction pipe 9. The other end of the first suction pipe 9 is connected to the external vacuuming device. Through the above setting, suction can be generated to achieve the purpose of collecting hair and dust.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The surfaces of the two cleaning blocks 6 that are close to each other and the outer surfaces of the two carding rollers 4 are polished. This setting can reduce the frictional resistance when the two are in contact and improve the service life. Two motors 14 are installed on one side of the leftmost support plate 2. The output end of each motor 14 is fixedly connected to one end of the carding shaft 3 that is close to it through a coupling. This setting can provide power for the rotation of the carding shaft 3.

[0036] The carding machine for recycled cotton yarn in this embodiment can effectively remove lint and dust from the surface of the carding needles 5 during the carding process. The design of the cleaning block 6, combined with the dust collection device, can generate strong suction to ensure that lint and dust are collected in time, avoiding interference from impurities on the carding effect and improving the purity and quality of the cotton yarn. By setting antistatic plates 11 with ion fans 12 at the front and rear ends of the support plate 2, static electricity on the carding needles 5 and cotton yarn can be effectively eliminated, reducing the problems of cotton yarn entanglement and carding needle adhesion caused by static electricity. This not only improves carding efficiency but also ensures the stability and continuity of the carding process. The rounded corner design of the edges of the cleaning groove 7 and the matching of the width of the cleaning groove 7 with the diameter of the carding needles 5 allow the carding needles 5 to smoothly enter the cleaning groove 7 during rotation, achieving a good scraping effect with the cleaning block 6.

[0037] The working principle of the above embodiment is as follows: First, the recycled cotton yarn to be combed is placed on the worktable 13, ensuring that the cotton yarn is within the working range of the carding roller 4. At this time, the motor 14 starts and drives the carding shaft 3 to rotate through the coupling, thereby driving the two carding rollers 4 to rotate synchronously. A set of staggered carding needles 5 are fixed on the outer surface of the carding roller 4. These carding needles 5 move in a circular motion as the carding roller 4 rotates, opening and combing the cotton yarn. During the carding process, the surface of the carding needles 5 will inevitably be contaminated with lint and dust. In order to keep the carding needles 5 clean, the carding machine is designed with two symmetrically arranged cleaning blocks 6, which are located on the outside of the two carding rollers 4 and in close contact with the outer surface of the carding rollers 4. A set of through cleaning grooves 7 are opened on the front of the cleaning blocks 6. The width of these cleaning grooves 7 matches the diameter of the carding needles 5 to ensure that the carding needles 5 are within the working range of the carding rollers 4. During rotation, the carding needles 5 can smoothly enter the cleaning trough 7. When the carding needles 5 pass through the cleaning trough 7, the lint and dust on their surface will be scraped off by the cleaning block 6. At the same time, the uppermost and lowermost cleaning troughs 7 are respectively provided with suction troughs 8. These suction troughs 8 are connected to the dust collection device through the first suction pipe 9 and the second suction pipe 10. The strong suction generated by the dust collection device will suck the lint and dust from the suction troughs 8 into the cleaning block 6 and enter the dust collection device through the pipe, thereby achieving effective collection and treatment of impurities. In addition, in order to eliminate the static electricity generated during the carding process, the carding machine is also equipped with antistatic plates 11 with ion fans 12 at the front and rear ends of the support plate 2. The ion fans 12 can release a large number of positive and negative ions. These ions will neutralize the static charge on the carding needles 5 and the cotton yarn, thereby effectively eliminating the influence of static electricity and reducing the problems of cotton yarn entanglement and carding needle 5 adhesion.
