Description
Technical Field
[0001] This application relates to the field of textile processing equipment technology, and in particular to the addition of fireproof devices to the final rolling rollers. Background Technology
[0002] The drawing frame is an important piece of equipment in textile production used to improve the internal structure of cotton slivers and enhance uniformity. It is mainly used to combine multiple cotton slivers into a single cotton sliver and to straighten and parallel the fibers through drafting, while also achieving the mixing of different raw materials.
[0003] However, the existing design of the bearings and rubber sleeves of the drawing frame rollers is not reasonable enough. After the yarn is wrapped around the shaft end, the high-speed friction between the spinning yarn and the bearing can easily cause high temperature and fire, which poses a great safety hazard. Utility Model Content
[0004] The purpose of this application is to provide a fireproof device for the final drawing roller, which can block and isolate the yarn wrapping at the shaft end, avoid high-temperature fire caused by high-speed friction between the yarn and the bearing, improve the safety of textile processing operations, and solve the problem that the existing drawing frame shaft end is prone to high-temperature fire due to high-speed friction between the yarn and the bearing when yarn wrapping.
[0005] The fireproof device for the final rolling roller provided in this application adopts the following technical solution: the fireproof device for the final rolling roller includes a roller shaft, a roller body is fixedly sleeved on the outer circumferential surface of the roller shaft, and fireproof covers are slidably sleeved on both ends of the roller shaft, with each fireproof cover in close contact with the roller body on the side closest to the roller body.
[0006] The roller body has grooves at both ends, and the roller body forms an isolation groove with the fireproof cover through the grooves at the ends.
[0007] By adopting the above technical solution, a fireproof cover is set at the end of the roller shaft, and a groove is set at the end of the roller body, so that an isolation groove is formed between the fireproof cover and the roller body. This can block and isolate the yarn wrapping at the shaft end, prevent the yarn from contacting the bearing, and thus avoid high temperature fire caused by high-speed friction between the yarn and the bearing, thereby improving the safety of textile processing operations.
[0008] Preferably, both ends of the roller shaft are provided with threaded structures, and the roller shaft is threadedly connected to a positioning cover through the threaded structures at the ends. The side of the positioning cover closest to the fireproof cover is in close contact with the fireproof cover.
[0009] By adopting the above technical solution, a threaded structure is set at both ends of the roller shaft and a positioning cover is threadedly connected. The positioning cover is in close contact with the fireproof cover on the side closest to the fireproof cover, thereby positioning the fireproof cover and making it fit tightly against the roller body. During installation, the threaded connection method makes the installation and removal of the positioning cover more convenient, without the need for complicated tools, saving time and labor costs. The close contact between the positioning cover and the fireproof cover can effectively and accurately position the fireproof cover, preventing it from shifting due to vibration or other reasons during operation, ensuring that the fireproof cover is always in the correct position and stably performs its fireproof isolation function.
[0010] Preferably, the positioning cover is made of aluminum alloy, and the outer circumferential surface of the positioning cover is integrally formed with equidistantly arranged anti-slip protrusions.
[0011] By adopting the above technical solution, aluminum alloy material has the characteristics of light weight and high strength. While ensuring the structural strength of the positioning cover, it will not add too much burden to the entire device, which is conducive to the lightweight design of the device and reduces energy consumption. When the operator needs to install or remove the positioning cover, the anti-slip protrusion can significantly increase the friction between the hand and the positioning cover, avoid operational errors caused by slipping, and improve the convenience of operation.
[0012] Preferably, the interior of the isolation groove and the outer surface of the fireproof cover are both coated with an antistatic coating.
[0013] By adopting the above technical solution, in the textile processing environment, fiber materials are prone to static electricity. Coating the inside of the isolation tank and the outer surface of the fireproof cover with an antistatic coating can effectively prevent the yarn from generating and accumulating static electricity due to friction, and also avoid static electricity attracting dust and other impurities, keeping the isolation tank and fireproof cover clean, ensuring that their fireproof isolation function is not affected, reducing the risk of fire caused by electrostatic discharge, further improving the safety of textile processing operations, and providing a more reliable guarantee for the production environment.
[0014] Preferably, both ends of the roller are provided with guide slopes, the ends of the guide slopes point to the isolation groove, and the guide slopes are coated with an antistatic coating.
[0015] By adopting the above technical solution, the presence of the guide slope provides a clear guide for the spinning yarn, which can guide the spinning yarn smoothly into the isolation groove area when the yarn is wound on the roller head, and avoid the spinning yarn from being disorderly wrapped around other parts of the roller end. At the same time, the antistatic coating can prevent the spinning yarn from generating static electricity due to friction when passing through the guide slope.
[0016] Preferably, each of the fireproof covers has a limiting ring fixedly connected to the side near the isolation groove, and the inner wall of the limiting ring is slidably sleeved with the outer circumferential surface of the roller.
[0017] By adopting the above technical solution, the setting of the limiting ring further enhances the connection stability between the fireproof cover and the roller body. During the operation of the device, it can effectively prevent the yarn wrapped around the shaft head from getting stuck in the gap between the fireproof cover and the roller body, which would bring great difficulties to the subsequent cleaning work of the wrapped yarn, and play an effective shielding role for the yarn.
[0018] Preferably, the end of the limiting ring away from the fireproof cover is beveled, the outer surface of the limiting ring is coated with an antistatic coating, and both the fireproof cover and the limiting ring are made of high-temperature resistant and fireproof material.
[0019] By adopting the above technical solutions, the chamfered angle makes the end of the limiting ring smoother. When the yarn wrapped around the shaft comes into contact with the limiting ring, it can smoothly slide into the interior of the isolation groove. The antistatic coating can prevent static electricity generated by friction when the limiting ring comes into contact with the yarn. The use of high-temperature resistant and fireproof materials ensures that the fireproof cover and the limiting ring can maintain their stable performance when facing the high-temperature environment that may be generated during textile processing, effectively playing a fireproof isolation role and avoiding material deformation, damage or fire caused by high temperature, thus providing a solid guarantee for the safety of textile processing.
[0020] Preferably, the outer circumferential surface of the roller body is fitted with a rubber sleeve, the two ends of the roller shaft are equipped with bearings, and the fireproof cover and the isolation groove are located between the roller body and the bearings.
[0021] By adopting the above technical solutions, the bearing can support the roller shaft, ensuring smooth rotation of the roller shaft, reducing rotational resistance, and improving transmission efficiency. Placing the fireproof cover and isolation groove between the roller body and the bearing can effectively isolate the tangled yarn from the shaft end, prevent the tangled yarn from contacting the bearing, and avoid high-temperature fire caused by high-speed friction between the yarn and the bearing. The fireproof isolation function is optimized from the structural layout, improving the safety and stability of textile processing operations.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] The end roller is equipped with a fireproof device. By setting a fireproof cover at the end of the roller shaft and a groove at the end of the roller body, an isolation groove is formed between the fireproof cover and the roller body. This can seal and isolate the yarn entanglement at the shaft end, preventing the yarn entanglement from contacting the bearing. This, in turn, prevents high-temperature fire caused by high-speed friction between the yarn and the bearing, improving the safety of textile processing operations. The positioning cover, which is threaded to the roller shaft, facilitates the positioning of the fireproof cover and also facilitates the installation and removal of the fireproof cover. By setting a guide angle limiting ring between the isolation groove and the fireproof cover, the yarn can be blocked, preventing the yarn from getting stuck in the gap between the fireproof cover and the roller body, which would affect the subsequent cleaning of the yarn entanglement.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0032] Example 1: Fireproof device installed on the final roller, refer to Figure 3 , Figure 4 and Figure 5 It includes a roller shaft 1, a roller body 2 fixedly sleeved on the outer circumference of the roller shaft 1, and fireproof covers 3 slidably sleeved on both ends of the roller shaft 1. Each fireproof cover 3 is in close contact with the roller body 2 on the side closest to the roller body 2. Grooves are provided at both ends of the roller body 2, and an isolation groove 4 is formed between the roller body 2 and the fireproof cover 3 through the grooves at the ends.
[0033] The interior of the isolation tank 4 and the exterior of the fireproof cover 3 are both coated with an antistatic coating. In the textile processing environment, fiber materials are prone to static electricity. The antistatic coating on the interior of the isolation tank 4 and the exterior of the fireproof cover 3 can effectively prevent the yarn from generating and accumulating static electricity due to friction, and also prevent static electricity from attracting dust and other impurities, keeping the isolation tank 4 and the fireproof cover 3 clean, ensuring that their fireproof isolation function is not affected, reducing the risk of fire caused by electrostatic discharge, further improving the safety of textile processing operations, and providing a more reliable guarantee for the production environment.
[0034] See Figure 2 , Figure 3 and Figure 4Both ends of the roller body 2 are provided with guide slopes 7, the ends of which point to the isolation groove 4. The guide slopes 7 are coated with an antistatic coating. The presence of the guide slopes 7 provides a clear guide for the spinning yarn, which can guide the spinning yarn smoothly into the isolation groove 4 area when the yarn is wound on the roller head, avoiding the spinning yarn from being disorderly wrapped around other parts of the end of the roller body 2. At the same time, the antistatic coating can prevent the spinning yarn from generating static electricity due to friction when passing through the guide slopes 7.
[0035] See Figure 1 , Figure 2 and Figure 3 The outer circumference of the roller body 2 is fitted with a rubber sleeve 9, and bearings 10 are installed at both ends of the roller shaft 1. The fireproof cover 3 and the isolation groove 4 are located between the roller body 2 and the bearings 10. The bearings 10 can support the roller shaft 1, ensuring the smooth rotation of the roller shaft 1, reducing rotational resistance, and improving transmission efficiency. The fireproof cover 3 and the isolation groove 4 are placed between the roller body 2 and the bearings 10 to effectively isolate the tangled yarn from the shaft end, prevent the tangled yarn from contacting the bearings 10, and avoid high-temperature fire caused by high-speed friction between the yarn and the bearings 10. The fireproof isolation function is optimized from the structural layout, and the safety and stability of textile processing operations are improved.
[0036] Example 2: Fireproof device installed on the final roller, refer to Figure 3 , Figure 4 and Figure 5 Both ends of the roller 1 are provided with threaded structures. The roller 1 is threadedly connected to the positioning cover 5 through the threaded structure at the ends. The side of the positioning cover 5 closest to the fireproof cover 3 is in close contact with the fireproof cover 3. By setting threaded structures at both ends of the roller 1 and threading the positioning cover 5 to it, and the side of the positioning cover 5 closest to the fireproof cover 3 being in close contact with the fireproof cover 3, the fireproof cover 3 is positioned so that it fits tightly against the roller body 2. During installation, the threaded connection makes the installation and removal of the positioning cover 5 more convenient, without the need for complicated tools, saving time and labor costs. The positioning cover 5 is in close contact with the fireproof cover 3, which can effectively and accurately position the fireproof cover 3, preventing it from shifting due to vibration or other reasons during operation, ensuring that the fireproof cover 3 is always in the correct position and stably performs its fireproof isolation function.
[0037] The positioning cover 5 is made of aluminum alloy. The outer circumference of the positioning cover 5 is integrally formed with equidistant anti-slip protrusions 6. Aluminum alloy is lightweight and high-strength. While ensuring the structural strength of the positioning cover 5, it will not add too much burden to the entire device, which is conducive to the lightweight design of the device and reduces energy consumption. When the operator needs to install or remove the positioning cover 5, the anti-slip protrusions 6 can significantly increase the friction between the hand and the positioning cover 5, avoid operational errors caused by slipping, and improve the convenience of operation.
[0038] Each fireproof cover 3 is fixedly connected to a limiting ring 8 on the side near the isolation groove 4. The inner wall of the limiting ring 8 is slidably sleeved with the outer circumferential surface of the roller body 2. The setting of the limiting ring 8 further enhances the connection stability between the fireproof cover 3 and the roller body 2. During the operation of the device, it can effectively prevent the yarn wrapped around the shaft head from getting stuck in the gap between the fireproof cover 3 and the roller body 2, which would bring great difficulties to the subsequent cleaning work of the wrapped yarn and play an effective shielding role for the yarn.
[0039] The end of the limiting ring 8 furthest from the fireproof cover 3 is beveled. The outer surface of the limiting ring 8 is coated with an antistatic coating. Both the fireproof cover 3 and the limiting ring 8 are made of high-temperature resistant and fireproof materials. The beveled design makes the end of the limiting ring 8 smoother. When the yarn wrapped around the spindle comes into contact with the limiting ring 8, it can smoothly slide into the interior of the isolation groove 4. The antistatic coating can prevent static electricity generated by friction when the limiting ring 8 comes into contact with the yarn. The use of high-temperature resistant and fireproof materials ensures that the fireproof cover 3 and the limiting ring 8 can maintain their stable performance when facing the high-temperature environment that may be generated during textile processing, effectively play a fireproof isolation role, and avoid material deformation, damage or fire caused by high temperature, thus providing a solid guarantee for the safety of textile processing.
[0040] The implementation principle of this application embodiment is as follows: A fireproof cover 3 is provided at the end of the roller shaft 1, and a groove is opened at the end of the roller body 2, forming an isolation groove 4. When the shaft end is entangled, the isolation groove 4 can effectively block and isolate the entangled material, preventing the entangled material from contacting the bearings 10 installed at both ends of the roller shaft 1. If the yarn rubs against the bearings 10 at high speed, high temperatures will be generated, which may lead to a fire. The fireproof cover 3 and the isolation groove 4 structurally block this dangerous path, improving the safety of textile processing operations. When installing the fireproof cover 3, first slide the fireproof cover 3 onto the end of the roller shaft 1, making it in close contact with the roller body 2. Then, by rotating the positioning cover 5, the fireproof cover 3 is pressed against the roller body 2 using a threaded connection, fixing the fireproof cover 3 to the end of the roller body 2, preventing it from shifting due to vibration or other reasons during operation. This threaded connection method makes the installation and removal of the positioning cover 5 more convenient, requiring no complicated tools and saving costs. It saves time and labor costs, and facilitates the replacement and maintenance of the fireproof cover 3. During the operation of the device, the limiting ring 8 further enhances the connection stability between the fireproof cover 3 and the roller 2, and blocks the gap between the fireproof cover 3 and the roller 2. It effectively prevents the yarn wrapped around the shaft from getting stuck in the gap between the fireproof cover 3 and the roller 2, thus preventing it from hindering the subsequent cleaning of the wrapped yarn. The end of the limiting ring 8 away from the fireproof cover 3 is set with a chamfer, making the end of the limiting ring 8 smoother. When the yarn wrapped around the shaft comes into contact with the limiting ring 8, it can smoothly slide into the interior of the isolation groove 4. The interior of the isolation groove 4, the outer surface of the fireproof cover 3, the guide slope 7, and the outer surface of the limiting ring 8 are all coated with an antistatic coating. These antistatic coatings can effectively prevent the yarn from generating static electricity due to friction and accumulating, avoid static electricity attracting dust and other impurities, keep the components clean, ensure that their fireproof isolation and other functions are not affected, and reduce the risk of fire caused by electrostatic discharge.
