Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a guide roller for a fabric inspection machine that provides anti-tangling rollers. Background Technology

[0002] In the textile production process, the fabric inspection machine is a key piece of equipment used to inspect the quality of fabric. It uses guide rollers to transport the fabric to the inspection area so that workers or testing devices can detect defects, textures, etc. of the fabric. As the core component of fabric transport, the stability of the guide rollers directly affects the working efficiency and inspection quality of the fabric inspection machine.

[0003] However, most of the guide rollers in existing fabric inspection machines are smooth cylindrical structures. During the fabric conveying process, due to the fabric's inherent flexibility and absorbency, especially at high speeds or when the fabric has high humidity, the fabric tends to adhere excessively to the outer wall of the guide roller, resulting in roller entanglement. Roller entanglement not only interrupts fabric conveying and affects inspection efficiency, but may also cause fabric wrinkles and damage, increasing production losses.

[0004] Therefore, it is necessary to provide a new type of anti-tangling roller for the fabric inspection machine guide roller to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric inspection machine guide roller with an anti-tangling roller that can improve the stability of fabric inspection machine operation, provide effective protection for the fabric, and improve the efficiency and quality of fabric inspection.

[0006] To solve the above-mentioned technical problems, the present invention provides a fabric inspection machine guide roller for an anti-tangle roller, comprising: a roller body and an anti-tangle component. Both ends of the roller body are fixedly installed with a linkage shaft. The anti-tangle component is arranged around the outer side wall of the roller body. The anti-tangle component includes several groups of anti-tangle protrusions evenly distributed along the axial direction of the roller body. Each group of anti-tangle protrusions includes several arc-shaped protrusions arranged at equal intervals along the circumference of the roller body. The arc-shaped protrusions are integrally formed or welded to the outer side wall of the roller body. The height of the arc-shaped protrusions is 3-8mm. A guide channel is formed between two adjacent groups of anti-tangle protrusions.

[0007] Furthermore, the roller body is made of stainless steel, and the outer wall of the arc-shaped protrusion is covered with a polytetrafluoroethylene coating with a coating thickness of 0.5-1mm.

[0008] Furthermore, the roller body has multiple weight-reducing cavities, which are evenly distributed along the axial direction of the roller body.

[0009] Furthermore, a number of guide protrusions are provided in the guide channel between two adjacent sets of anti-tangling protrusions. The guide protrusions are fixedly connected to the outer wall of the roller body, and the height of the guide protrusions is 1-2mm.

[0010] Furthermore, each side of the roller body is provided with a frame mounting plate, and a drive shaft is rotatably mounted on each of the two frame mounting plates. A shaft groove is opened on the side of the two drive shafts that are close to each other. The two linkage shafts are respectively located in the two shaft grooves. A rectangular slot is opened on each of the two drive shafts. The two rectangular slots are respectively connected to the two shaft grooves. A rectangular plug is inserted into each of the two rectangular slots. The ends of the two linkage shafts that are far apart from each other are respectively fixedly connected to the two rectangular plugs.

[0011] Furthermore, each of the two rectangular inserts has a positioning hole, and each of the two drive shafts has a U-shaped support fixedly installed at its bottom. Each of the two U-shaped supports has a connecting piece inside, and each of the two connecting pieces has a positioning lever fixedly installed at its top. The top ends of each of the two positioning levers extend into the corresponding positioning holes, and the two positioning levers are slidably connected to the two drive shafts respectively. Each of the two U-shaped supports has a threaded post threaded on one side, and the same-direction ends of the two threaded posts extend into the two U-shaped supports and are rotatably connected to the corresponding connecting pieces. Each of the two U-shaped supports has two guide rods fixedly installed inside, and the corresponding two guide rods pass through the corresponding connecting pieces and are slidably connected to the corresponding connecting pieces.

[0012] Furthermore, a knob is fixedly installed at the end of each of the two threaded posts away from the connecting piece, and a spring washer is fitted on each of the two threaded posts. The two spring washers abut against one side of the outer wall of each of the two U-shaped supports, and the two knobs abut against the two spring washers respectively.

[0013] Compared with related technologies, the anti-tangling roller of the fabric inspection machine provided by this utility model has the following beneficial effects: I.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-5 The fabric inspection machine guide roller of the anti-winding roller includes: roller body 1 and anti-winding component 3. Roller body 1 is made of stainless steel and a linkage shaft 8 is fixedly installed at both ends of roller body 1. Anti-winding component 3 is arranged around the outer wall of roller body 1. Anti-winding component 3 includes several groups of anti-winding protrusions 301 evenly distributed along the axial direction of roller body 1. Each group of anti-winding protrusions 301 includes several arc-shaped protrusions arranged at equal intervals along the circumference of roller body 1. The arc-shaped protrusions are integrally formed or welded to the outer wall of roller body 1. The height of the arc-shaped protrusions is 5mm, and the outer wall of the arc-shaped protrusions is covered with a 0.8mm thick polytetrafluoroethylene coating. The coating is formed by spraying process and the surface smoothness Ra≤0.8μm, which significantly reduces the coefficient of friction with the fabric. A guide channel 302 is formed between two adjacent sets of anti-tangling protrusions 301, and a number of guide protrusions 303 are provided in the guide channel 302. The guide protrusions 303 are fixedly connected to the outer wall of the roller body 1. The guide protrusions 303 are hemispherical structures with a height of 1.5mm, which play a stable guiding role for the fabric.

[0018] In addition, multiple weight-reducing cavities 2 are provided inside the roller body 1. These multiple weight-reducing cavities 2 are evenly distributed along the axial direction of the roller body 1, which can reduce the overall weight of the roller body 1 and effectively reduce the load on the transmission system.

[0019] In this embodiment, to facilitate the assembly and disassembly of the roller body 1, frame mounting plates 4 are provided on both sides of the roller body 1. A drive shaft 5 is rotatably mounted on each of the two frame mounting plates 4. Shaft grooves 7 are formed on the sides of the two drive shafts 5 that are close to each other. Two linkage shafts 8 are respectively located within the two shaft grooves 7. Rectangular slots 6 are formed on each of the two drive shafts 5, and the two rectangular slots 6 are respectively connected to the two shaft grooves 7. Rectangular inserts 9 are inserted into each of the two rectangular slots 6. The ends of the two linkage shafts 8 that are far apart from each other are respectively fixedly connected to the two rectangular inserts 9. Positioning holes 10 are formed on each of the two rectangular inserts 9. U-shaped supports 11 are fixedly mounted on the bottom of each of the two drive shafts 5, and connecting pieces 1 are provided within each of the two U-shaped supports 11. 3. Positioning levers 14 are fixedly installed on the top of each of the two connecting pieces 13. The top ends of the two positioning levers 14 extend into the corresponding positioning holes 10, and the two positioning levers 14 are slidably connected to the two drive shafts 5 respectively. Threaded posts 12 are threadedly installed on one side of each of the two U-shaped supports 11. The same-direction ends of the two threaded posts 12 extend into the two U-shaped supports 11 and are rotatably connected to the corresponding connecting pieces 13. Two guide rods are fixedly installed in each of the two U-shaped supports 11. The corresponding two guide rods pass through the corresponding connecting pieces 13 and are slidably connected to the corresponding connecting pieces 13. By rotating the threaded posts 12, the positioning levers 14 can be quickly brought into or out of the positioning holes 10, thus achieving a quick assembly and disassembly effect.

[0020] In the above method, in order to ensure that the positioning lever 14 is stably inserted into the positioning hole 10, a knob is fixedly installed at the end of each of the two threaded posts 12 away from the connecting piece 13, and a spring washer is fitted on each of the two threaded posts 12. The two spring washer abuts against the outer wall of one side of each of the two U-shaped supports 11, and the two knobs abut against the two spring washer respectively, which plays a role in relaxing and improving reliability.

[0021] The working principle of the guide roller of the fabric inspection machine for the anti-tangling roller provided by this utility model is as follows: In the initial state, both frame mounting plates 4 are installed on the fabric inspection machine. Then, the linkage shafts 8 at both ends of the roller body 1 are aligned with the shaft grooves 7 opened on the drive shaft 5, so that the linkage shafts 8 are embedded in the shaft grooves 7. At the same time, ensure that the rectangular inserts 9 fixed at the ends of the linkage shafts 8 are inserted into the rectangular slots 6 on the drive shaft 5, thus completing the initial connection between the roller body 1 and the drive shaft 5. This connection method can achieve synchronous rotation of the two and avoid relative slippage. Then, rotate the knob at the end of the threaded column 12 to drive the threaded column 12 to rotate on the U-shaped support 11. Since the threaded column 12 is rotatably connected to the connecting piece 13, and the connecting piece 13 is guided and limited in the U-shaped support 11 by the guide rod, the rotation of the threaded column 12 will push the connecting piece 13 to move along the guide rod. When the connecting piece 13 moves, the positioning folding rod 14 fixed at its top moves accordingly, and finally the top of the positioning folding rod 14 is inserted into the positioning hole 10 on the rectangular insert 9, which firmly fixes the rectangular insert 9 in the rectangular slot 6, thereby realizing the stable connection between the roller body 1 and the drive shaft 5 and preventing the two from separating during the operation. At the same time, the spring washer sleeved on the threaded column 12 abuts against the outer wall of the U-shaped support 11 and the knob, which can play an anti-loosening role and ensure the reliability of the connection. When the fabric is conveyed on the roller 1, the arc-shaped protrusions can provide spaced support for the fabric, preventing the fabric from sticking tightly to the surface of the roller 1 due to its own tension or the adsorption force generated by the rotation of the roller 1, and preventing the edges or local fibers of the fabric from getting tangled on the roller 1. At the same time, the polytetrafluoroethylene coating wrapped on the outer wall of the arc-shaped protrusions can reduce the friction between the fabric and the arc-shaped protrusions, further reducing the risk of tangling and protecting the surface of the fabric from damage. Meanwhile, the guide channel 302 formed between two adjacent sets of anti-tangling protrusions 301 provides a clear conveying path for the fabric, ensuring that the fabric moves stably along a fixed direction on the roller 1, avoiding problems such as offset and wrinkles during the conveying process, and ensuring the smooth progress of the fabric inspection work. In addition, during the conveying process, the guide protrusions 303 set in the guide channel 302 can further limit and guide the fabric, enhance the stability of the fabric in the guide channel 302, prevent the fabric from sliding laterally in the guide channel 302, and further improve the guiding accuracy.

[0022] Compared with related technologies, the anti-tangling roller of the fabric inspection machine provided by this utility model has the following beneficial effects: I. This utility model forms a physical gap by anti-winding protrusions 301, which prevents the fabric from sticking to the roller 1, blocks the winding path, and reduces the risk of machine stoppage and fabric damage; and the arc-shaped protrusions are coated with polytetrafluoroethylene, which reduces friction, prevents fiber entanglement, and protects the surface of the fabric. Second, this utility model constrains the trajectory of the fabric through the guide channel 302 between the anti-tangling protrusions 301, which can prevent deviation and wrinkles, ensure that the fabric is in the inspection field of view, and improve the accuracy of fabric inspection; the guide protrusions 303 in the guide channel 302 can form a secondary limit to prevent the fabric from sliding, especially suitable for thin fabrics, reducing missed detection and false detection. Third, this utility model, through the cooperation of the threaded post 12 and the connecting piece 13, can quickly install and remove the roller body 1 by screwing the threaded post 12, which is convenient for subsequent replacement and maintenance.
