Description

Technical Field

[0001] This utility model relates to the field of combed cylinder technology, specifically to an automatic tooth pitch adjustment device for the front zone of a combed cylinder. Background Technology

[0002] The cylinder is the core combing component in a combing machine. Its function is to comb the fiber bundles, removing neps, impurities, and short fibers, and improving fiber parallelism, straightness, and separation. With the increasing demands for high-speed, high-output combing machines and higher combing quality, the overall cylinder combing surface area is increasing, and the density of the teeth is also constantly increasing to improve the overall cylinder combing degree and effect. Currently, the cylinder and teeth are mostly uniformly cast, and their tooth spacing is mostly fixed, making it difficult to adjust according to actual conditions. Therefore, designing an automatic tooth spacing adjustment device for the front area of ​​the combing cylinder is very important. For example:

[0003] The invention, authorized by announcement number CN106120029B, discloses a small-arc surface low-carding-intensity combed cylinder. This invention addresses the problems of high carding density and high cotton waste rate in existing combed cylinders by designing a small-arc surface low-carding-intensity combed cylinder suitable for modern high-efficiency combing machines spinning coarser yarns with lower combing quality requirements. Based on actual production experience and cylinder parameter design principles, the total number of teeth, cylinder arc angle, number of zones, and the tooth parameters of each zone are rationally determined. Compared with existing technologies, this invention offers the following advantages: while maintaining a relatively constant tooth density in each zone, the carding surface is reduced by approximately 50%, and the number of zones is also reduced. First, the reduced carding surface of the cylinder effectively reduces the total number of teeth, thus meeting the requirements of low cotton shedding in combed yarn. Second, the reduced arc surface of the cylinder effectively reduces its weight and energy consumption, and also avoids collisions caused by improper fit between the cylinder and the clamping plate, thus contributing to safe equipment operation. In addition, fewer zones help reduce the phenomenon of cylinder inlay, while also reducing the manufacturing difficulty and processing cost of combed cylinders.

[0004] Based on existing solutions and actual production and processing, the current combed cylinders have the following defects, such as:

[0005] While existing combed cylinders reduce manufacturing difficulty and processing costs, their internal tooth pitch is mostly fixed, limiting their application and reducing work efficiency. Therefore, this invention provides an automatic tooth pitch adjustment device for the front area of ​​a combed cylinder to solve the aforementioned problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an automatic tooth pitch adjustment device for the front area of ​​a combing cylinder, comprising a cylinder body 1, a needle tooth frame 2, fixed needle teeth 3, moving needle teeth 4, a limiting block 5, a first limiting plate 6, a limiting bolt 7, a second limiting plate 8, an adjustment chamber 9, a connecting seat 10, a connecting plate 11, a connecting hole 12, a stabilizing frame 13, a connecting bolt 14, a positioning rod 15, an adjusting rod 16, a clamping seat 17, a motor 18, a protective chamber 19, a rear cover 20, a clamping frame 21, a fastening bolt 22, and a guide groove 23.

[0029] Specific examples Figure 1 and Figure 3 As shown, first, the cylinder body 1 is placed horizontally, and the inner wall of the needle tooth frame 2 is aligned with the right side of the cylinder body 1. The outer side of the cylinder body 1 is provided with a limiting block 5 set at equal angles. The fixed needle tooth 3 is set at equal angles about the center of the needle tooth frame 2. After the cylinder body 1 and the needle tooth frame 2 are aligned, the needle tooth frame 2 is pressed so that the inner wall of the needle tooth frame 2 is close to the outer side of the cylinder body 1. The rear side of the fixed needle tooth 3 rubs against the front side of the cylinder body 1. The fixed needle tooth 3 is set at equal angles about the center of the needle tooth frame 2. The rear side of the cylinder body 1 rubs against the front side of the second limiting plate 8. The cylinder body 1, the fixed needle tooth 3 and the second limiting plate 8 are all slidably connected until the right side of the cylinder body 1 contacts the inner side of the needle tooth frame 2. At this time, the limiting block 5 on the front side of the cylinder body 1 is alternately connected with the first limiting plate 6 on the front side of the needle tooth frame 2, and the limiting block 5 on the rear side of the cylinder body 1 is alternately connected with the second limiting plate 8 on the rear side of the needle tooth frame 2.

[0030] On the front side of the cylinder body 1, the limiting block 5 is engaged with the first limiting plate 6. On the rear side of the cylinder body 1, the limiting block 5 is engaged with the second limiting plate 8. The limiting bolt 7 is manually tightened. The limiting bolt 7 is a rod-shaped structure with external threads. When the limiting bolt 7 is tightened, the limiting bolt 7 passes through the interior of the second limiting plate 8. The second limiting plate 8 and the first limiting plate 6 are arranged in a front-to-back correspondence. The connection gap between the first limiting plate 6, the cylinder body 1, and the second limiting plate 8 is shortened. The cylinder body 1 is clamped by the first limiting plate 6 and the second limiting plate 8. The limiting bolt 7 is connected to the inner thread of the first limiting plate 6, so that the cylinder body 1 is connected and reinforced with the needle frame 2, which facilitates the positioning and assembly of the combing cylinder and the needles.

[0031] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, first, align the connecting plate 11 with the groove inside the stabilizer 13, push the connecting plate 11 so that the outer side of the connecting plate 11 slides against the inner side of the stabilizer 13 until the connecting plate 11 and the stabilizer 13 are engaged. Then, screw the connecting bolt 14 perpendicular to the stabilizer 13. The outer side of the connecting bolt 14 is provided with a threaded structure. When the connecting bolt 14 is screwed, the connection gap between the stabilizer 13 and the connecting plate 11 is shortened. Both the stabilizer 13 and the connecting plate 11 are threadedly connected to the connecting bolt 14. The connecting plate 11 and the stabilizer 13 are engaged relative to each other. The inner side of the stabilizer 13 is slidably connected with a positioning rod 15. The rear side of the moving pin tooth 4 is provided with a connecting seat 10, and the connecting seats 10 are evenly spaced on the connecting plate 11.

[0032] Next, align one end of the connecting plate 11 with the equally spaced connecting seats 10 with the adjustment chamber 9 inside the pin tooth frame 2, so that the entire stabilizing frame 13 extends into the adjustment chamber 9. Align the engagement frame 21 on the front side of the rear cover 20 with the rear opening of the pin tooth frame 2. Push the rear cover 20 so that the positioning rod 15 and the adjustment rod 16 connected to the rear cover 20 pass through the interior of the stabilizing frame 13 and the connecting hole 12 inside the connecting plate 11, and connect with the engagement seat 17 inside the pin tooth frame 2. When the rear cover 20 is pushed, the outer side of the engagement frame 21 rubs against the inner wall of the pin tooth frame 2, and the engagement frame 21 slides with the pin tooth frame 2 until the rear cover 20 on the rear side of the engagement frame 21 contacts the pin tooth frame 2, and the engagement frame 21 engages with the interior of the pin tooth frame 2.

[0033] Finally, tighten the fastening bolt 22. The threaded mechanism on the outside of the fastening bolt 22 reinforces the connection between the needle tooth frame 2 and the clamping frame 21. Both the clamping frame 21 and the needle tooth frame 2 are threadedly connected to the fastening bolt 22. The fastening bolt 22 is symmetrically arranged about the center line of the needle tooth frame 2, which facilitates the quick replacement of the comb cylinder needles.

[0034] Specific examples Figure 1 , Figure 2 and Figure 4 As shown, when the combed cylinder is used in the fine needle area, simply connect the power supply to the motor 18 inside the protective chamber 19. After the motor 18 is turned on, it drives the adjusting rod 16 connected to the front to rotate. The adjusting rod 16 has a threaded structure on the outside and passes through the connecting hole 12 inside the stabilizer 13 and the connecting plate 11. When the adjusting rod 16 rotates, it drives the stabilizer 13 to move. The adjusting rod 16 and the stabilizer 13 are threadedly connected. The outer wall of the stabilizer 13 slides in the adjusting chamber 9 inside the needle tooth frame 2 until the connecting plate 11 is connected to the front of the connecting plate 11. The receiving seat 10 contacts the needle frame 2. The fixed needle teeth 3 and the guide groove 23 are alternately arranged on the needle frame 2. There is a set of moving needle teeth 4 between two adjacent sets of fixed needle teeth 3. The moving needle teeth 4 are led out from the guide groove 23 opened inside the needle frame 2. At this time, the number of needle teeth set in the combing cylinder increases and the tooth pitch is shortened. Similarly, when the combing cylinder needs to be used in the coarse needle area, it is only necessary to ensure that the moving needle teeth 4 are deeply inserted into the adjustment chamber 9, so as to realize the automatic tooth pitch adjustment function of the front area of ​​the combing cylinder. This is the usage method of the automatic tooth pitch adjustment device of the front area of ​​the combing cylinder.
