Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and in particular to a combing head device that is easy to disassemble. Background Technology

[0002] Carding machines are a common type of textile machinery used in the needle-punched felt processing industry. In high-end, high-precision carding machines, the carding device has become an indispensable pre-treatment component. The carding device opens and separates the cotton laps from the previous process, so as to comb the crimped, lumpy, or bundled cotton laps into looser and straighter cotton fibers, which helps to improve the quality of yarn produced by the carding machine in the subsequent process.

[0003] Traditional carding machines primarily utilize the raised teeth on the licker-in roller to open and separate the cotton lap. However, a common problem with existing technologies is that the licker-in roller teeth and the roller body are usually integrally molded. With prolonged use, the licker-in roller teeth inevitably wear down, flatten, or break. Once the teeth are damaged, operators must disassemble and replace the entire licker-in roller to ensure effective carding and final yarn quality. This is not only cumbersome and time-consuming, but also significantly increases the maintenance and operating costs of the carding machine due to the need to replace the entire licker-in roller assembly. To address this technical challenge, there is an urgent need for a carding head device that allows for easy replacement of the licker-in roller teeth without requiring the complete replacement of the licker-in roller. Utility Model Content

[0004] This application provides a convenient disassembly carding head device, which solves the problem in the prior art where the licker-in roller and the licker-in roller body are usually made of one piece. As the licker-in roller is used for a long time, the licker-in roller on its surface will inevitably wear, collapse or break. Once the licker-in roller is damaged, in order to ensure the carding effect and the final yarn quality, the operator has to disassemble the entire licker-in roller for replacement. This is not only cumbersome and time-consuming, but also significantly increases the maintenance and use cost of the carding machine because the entire licker-in roller component needs to be replaced.

[0005] The technical solution adopted in the embodiments of this application is as follows:

[0006] A detachable carding head device includes a carding chamber, a needle assembly for carding cotton laps, a rotating roller rotatably connected to the inner cavity of the carding chamber, a guide roller rotatably connected to the inner cavity of the carding chamber, a drive device installed on the left side of the carding chamber, a transmission device for driving the guide roller to rotate, and a top cover for covering the carding chamber; the top cover is installed at the top opening of the carding chamber; two sets of needle assemblies are symmetrically arranged on the rotating roller; the output shaft of the drive device is connected to the rotating roller; the transmission device is located between the rotating roller and the guide roller; the front side of the carding chamber has an inlet for receiving cotton laps transported from the previous process of the carding machine; the top cover has an outlet for transporting carded cotton fibers to the subsequent feeding mechanism of the carding machine; the bottom of the carding chamber has an installation interface for fixed installation to a corresponding position on the carding machine.

[0007] A further technical solution is as follows: the needle assembly includes a protrusion, an arc-shaped support plate surrounding the rotating roller, needles for combing cotton rolls, and a fixing member for fixing the protrusion; the arc-shaped support plate has protrusions at both ends; the arc-shaped support plate has several sets of needles arranged in a rectangular array; the rotating roller has U-shaped limiting blocks at positions corresponding to the protrusions; the fixing member is connected to the U-shaped limiting blocks and the protrusions.

[0008] A further technical solution is as follows: the transmission device includes a first gear, a second gear for driving the first gear to rotate, a first connecting rod disposed at one end of the guide roller, and a second connecting rod disposed at one end of the rotating roller; the first gear and the second gear mesh with each other; the first gear is disposed on the first connecting rod; and the second gear is disposed on the second connecting rod.

[0009] A further technical solution is that a bent handle is provided on the top cover.

[0010] A further technical solution is that the driving device is an electric motor.

[0011] A further technical solution is that the fastener is a bolt.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. Due to the arrangement of a combing bin, needle assembly, rotating roller, guide roller, drive unit, transmission unit, and top cover, the operator first guides the cotton roll into the combing bin from the feed inlet. Then, the cotton roll passes between the rotating roller and the guide roller, and finally exits from the discharge outlet. Next, the operator drives the rotating roller to rotate via the output shaft of the drive unit. Since the transmission unit on the rotating roller is connected to the guide roller, when the drive unit's output shaft drives the rotating roller to rotate, it also drives the guide roller to rotate. The simultaneous rotation of the rotating roller and the guide roller achieves the conveying of the cotton roll. Because two sets of needle assemblies are arranged around the rotating roller, when the rotating roller rotates, it also drives the two sets of needle assemblies to rotate. At this time, when the cotton roll passes between the rotating roller and the guide roller, the needle assemblies on the rotating roller comb the cotton roll. Since both sets of licker-in components are detachably and fixedly mounted on the rotating roller, when the licker-in components are damaged during the carding process, the operator can directly disassemble and replace the licker-in components mounted on the rotating roller by opening the top cover of the carding chamber. The entire operation is simple, reliable, and easy for operators to operate. At the same time, it can reduce the maintenance cost of the carding head device to a certain extent. Therefore, it solves the technical problem that in the existing technical solution, the licker-in teeth and the licker-in roller body are usually made of one piece. With the long-term use of the licker-in roller, the licker-in teeth on its surface will inevitably wear, collapse, or break. Once the licker-in teeth are damaged, in order to ensure the carding effect and the final yarn quality, the operator has to disassemble the entire licker-in roller for replacement. This is not only cumbersome and time-consuming, but also significantly increases the maintenance and use cost of the carding machine because the entire licker-in roller component needs to be replaced.

[0014] 2. Due to the use of protrusions, arc-shaped support plates, needles, fixing components, and U-shaped limiting blocks, when the cotton roll passes between the rotating roller and the guide roller, the rotation of the rotating roller, which has two sets of needle assemblies fixedly installed on it, causes the two sets of arc-shaped support plates to rotate together. At this time, the needles fixedly connected to the arc-shaped support plates will comb the cotton roll. Since the protrusions fixedly connected to both ends of the arc-shaped support plates are fixedly installed on the corresponding U-shaped limiting blocks by fixing components, when the needles on the arc-shaped support plates are damaged, the operator only needs to disassemble the fixing components one by one to remove and replace the arc-shaped support plates. The entire operation process is simple and reliable, and can reduce maintenance costs.

[0015] 3. Due to the arrangement of the first gear, second gear, first connecting rod, and second connecting rod, when the output shaft of the drive device drives the rotating roller to rotate, the second connecting rod is fixedly connected to one end of the rotating roller, and the second gear is mounted on the second connecting rod. Therefore, when the rotating roller rotates, it drives the second gear to rotate as well. Since the second gear meshes with the first gear, when the second gear rotates, it drives the first gear to rotate as well. Since the first gear is fixedly connected to the first connecting rod, and the first connecting rod is fixedly connected to one end of the guide roller, when the first gear rotates, it drives the guide roller to rotate. Thus, through the rotation of the output shaft of the drive device, the guide roller and the rotating roller can rotate together.

[0016] 4. Due to the use of a bendable handle, staff can easily lift and open the top cover by bending the handle, making it more convenient for staff to operate. Attached Figure Description

[0022] This application provides a convenient disassembly carding head device, which solves the problem in the prior art where the licker-in roller and the licker-in roller body are usually made of one piece. As the licker-in roller is used for a long time, the licker-in roller on its surface will inevitably wear, collapse or break. Once the licker-in roller is damaged, in order to ensure the carding effect and the final yarn quality, the operator has to disassemble the entire licker-in roller for replacement. This is not only cumbersome and time-consuming, but also significantly increases the maintenance and use cost of the carding machine because the entire licker-in roller component needs to be replaced.

[0023] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] A detachable combing head device, such as Figure 1 and Figure 2 As shown, the device includes a carding chamber 1, a needle assembly 2 for carding cotton laps, a rotating roller 3 rotatably connected to the inner cavity of the carding chamber 1, a guide roller 4 rotatably connected to the inner cavity of the carding chamber 1, a drive device 5 installed on the left side of the carding chamber 1, a transmission device 6 for driving the guide roller 4 to rotate, and a top cover 7 for covering the carding chamber 1. The top cover 7 is installed at the top opening of the carding chamber 1. Two sets of needle assemblies 2 are symmetrically arranged on the rotating roller 3. The output shaft of the drive device 5 is connected to the rotating roller 3. The transmission device 6 is located between the rotating roller 3 and the guide roller 4. The front side of the carding chamber 1 is provided with an inlet 11 for receiving the cotton laps conveyed in the previous process of the carding machine. The top cover 7 is provided with an outlet 12 for conveying the carded cotton fibers to the subsequent feeding mechanism of the carding machine. The bottom of the carding chamber 1 is provided with an installation interface for fixing and installing it to the corresponding position of the carding machine.

[0026] The top cover 7 is detachably fitted onto the top opening of the combing chamber 1. Two sets of symmetrically arranged barbed needle assemblies 2 are detachably fixedly mounted on the rotating roller 3. The drive unit 5 is detachably fixedly mounted on the left side of the combing chamber 1 by bolts. The drive unit 5 is preferably a motor. The output shaft of the drive unit 5 is driven and connected to the rotating roller 3. The transmission device 6 is fixedly connected between the rotating roller 3 and the guide roller 4. The rotating roller 3 and the guide roller 4 are placed close to each other. When the output shaft of the drive unit 5 drives the rotating roller 3 to rotate, the transmission device 6 will drive the guide roller 4 to rotate together. A feed inlet 11 is fixedly connected to the front side of the combing chamber 1. A discharge outlet 12 is fixedly connected to the top cover 7.

[0027] The system comprises a combing chamber 1, needle assembly 2, rotating roller 3, guide roller 4, drive device 5, transmission device 6, and top cover 7. First, the operator guides the cotton roll into the combing chamber 1 through the feed inlet 11. Then, the cotton roll passes between the rotating roller 3 and guide roller 4, and finally exits through the discharge outlet 12. Next, the operator drives the rotating roller 3 to rotate via the output shaft of the drive device 5. Since the transmission device 6, mounted on the rotating roller 3, is connected to the guide roller 4, the rotation of the rotating roller 3 by the output shaft of the drive device 5 also drives the guide roller 4 to rotate. The simultaneous rotation of the rotating roller 3 and guide roller 4 enables the conveying of the cotton roll. Because the two sets of needle assemblies 2 are arranged around the rotating roller 3, their rotation also causes the rotating roller 3 to rotate. When the cotton roll passes between the rotating roller 3 and guide roller 4, the needle assembly 2 on the rotating roller 3 combs the cotton roll. Since both sets of needle assembly 2 can be detachably fixed on the rotating roller 3, when the needle assembly 2 is damaged during the carding process, the operator can directly disassemble and replace the needle assembly 2 installed on the rotating roller 3 by opening the top cover 7 at the top of the carding chamber 1. The whole operation process is simple and reliable, and easy for the operator to operate. At the same time, it can reduce the maintenance cost of the carding head device to a certain extent. Therefore, it solves the technical problem that in the existing technical solution, the needle teeth on the licker-in roller and the licker-in roller body are usually made of one piece. With the long-term use of the licker-in roller, the needle teeth on its surface will inevitably wear, collapse or break. Once the needle teeth are damaged, in order to ensure the carding effect and the final yarn quality, the operator has to disassemble the entire licker-in roller for replacement. This is not only cumbersome and time-consuming, but also significantly increases the maintenance and use cost of the carding machine because the entire licker-in roller part needs to be replaced.

[0028] like Figure 3 As shown, the needle assembly 2 includes a protrusion 21, an arc-shaped support plate 22 surrounding the rotating roller 3, needles 23 for combing cotton rolls, and a fixing member 24 for fixing the protrusion 21. Protrusions 21 are provided at both ends of the arc-shaped support plate 22. Several groups of needles 23 arranged in a rectangular array are provided on the arc-shaped support plate 22. U-shaped limiting blocks 31 are provided on the rotating roller 3 at positions corresponding to the protrusions 21. The fixing member 24 connects the U-shaped limiting blocks 31 and the protrusions 21.

[0029] The vertical surface of the arc-shaped support plate 22 is preferably semi-circular. Both ends of the arc-shaped support plate 22 are fixedly connected to protrusions 21. Several sets of needles 23 arranged in a rectangular array are fixedly connected to the arc-shaped support plate 22. U-shaped limiting blocks 31 are fixedly installed on the rotating roller 3 at positions corresponding to each set of protrusions 21. The U-shaped limiting blocks 31 are adapted to the protrusions 21. When the protrusions 21 at both ends of the arc-shaped support plate 22 are respectively inserted into the corresponding U-shaped limiting blocks 31, the arc-shaped support plate 22 will then adhere to the rotating roller 3. The fixing element 24 is preferably a bolt. Each set of U-shaped limiting blocks 31 is provided with a fixing element 24. Each set of fixing elements 24 passes through the corresponding U-shaped limiting block 31 and is threadedly connected to the corresponding protrusion 21.

[0030] Because of the use of protrusions 21, arc-shaped support plates 22, needles 23, fixing parts 24, and U-shaped limiting blocks 31, when the cotton roll passes between the rotating roller 3 and the guide roller 4, the rotation of the rotating roller 3, which has two sets of needle assemblies 2 fixedly installed on it, will cause the two sets of arc-shaped support plates 22 to rotate together. At this time, the needles 23 fixedly connected to the arc-shaped support plates 22 will comb the cotton roll. Since the protrusions 21 fixedly connected to both ends of the arc-shaped support plates 22 are fixedly installed on the corresponding U-shaped limiting blocks 31 through fixing parts 24, when the needles 23 on the arc-shaped support plates 22 are damaged, the operator only needs to disassemble the fixing parts 24 in sequence to disassemble and replace the arc-shaped support plates 22. The whole operation process is simple and reliable, and can reduce maintenance costs.

[0031] like Figure 4 As shown, the transmission device 6 includes a first gear 61, a second gear 62 for driving the first gear 61 to rotate, a first connecting rod 63 disposed at one end of the guide roller 4, and a second connecting rod 64 disposed at one end of the rotating roller 3. The first gear 61 and the second gear 62 mesh with each other. The first gear 61 is disposed on the first connecting rod 63. The second gear 62 is disposed on the second connecting rod 64.

[0032] The first connecting rod 63 is fixedly connected to one end of the guide roller 4. The second connecting rod 64 is fixedly connected to one end of the rotating roller 3. The first gear 61 is fixedly connected to the first connecting rod 63. The second gear 62 is fixedly connected to the second connecting rod 64.

[0033] Due to the arrangement of the first gear 61, the second gear 62, the first connecting rod 63, and the second connecting rod 64, when the output shaft of the drive device 5 drives the rotating roller 3 to rotate, the second connecting rod 64 is fixedly connected to one end of the rotating roller 3, and the second gear 62 is mounted on the second connecting rod 64. Therefore, when the rotating roller 3 rotates, it drives the second gear 62 to rotate as well. Since the second gear 62 is meshed with the first gear 61, when the second gear 62 rotates, it drives the first gear 61 to rotate as well. Since the first gear 61 is fixedly connected to the first connecting rod 63, and the first connecting rod 63 is fixedly connected to one end of the guide roller 4, when the first gear 61 rotates, it drives the guide roller 4 to rotate. Thus, through the rotation of the output shaft of the drive device 5, the guide roller 4 and the rotating roller 3 can rotate together.

[0034] like Figure 1 As shown, a bent handle 71 is provided on the top cover 7.

[0035] Both ends of the top cover 7 are fixedly connected with bent handles 71.

[0036] Thanks to the design of the bending handle 71, staff can easily lift and open the top cover 7 by bending the handle 71, making it more convenient for staff to operate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
