Description

Technical Field

[0001] This utility model relates to the field of textile accessories technology, and in particular to an improved paper tube clamping plate. Background Technology

[0002] In the texturing machine production process, the paper tube is a key component used for winding the yarn, and its specifications must match the production requirements. Currently, the paper tubes used in conventional texturing machines are mostly standard specifications with inner diameters of 69mm and 53mm, but in actual production, different batches or different types of products may require switching to paper tubes with different inner diameters.

[0003] Existing texturing machine chucks typically only accommodate one type of paper tube. When changing to paper tubes with different inner diameters, the entire chuck must be replaced. Changing the chuck not only requires machine downtime and is time-consuming, but frequent disassembly and reassembly can also reduce the chuck's positioning accuracy, affecting the stability of subsequent production and ultimately reducing overall processing efficiency. Furthermore, for paper tubes with non-standard inner diameters, custom-made chucks are often necessary, further increasing production costs and management complexity.

[0004] Therefore, there is an urgent need for a clamping structure that can adapt to various paper tube specifications, does not require frequent replacement, and has high stability, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an improved paper tube clamp that can be adapted to various specifications of paper tubes, allowing for the switching of different paper tubes without changing the clamp, thereby improving production efficiency while ensuring the stability and positioning accuracy of paper tube clamping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An improved paper tube clamp includes a clamp body. One side of the clamp body is formed with a base plate, a large-diameter circular boss and a small-diameter circular boss arranged coaxially. The large-diameter circular boss connects the base plate and the small-diameter circular boss. The other side of the clamp body is formed with a connecting seat.

[0007] In use, the clamping discs are connected to the corresponding components of the texturing machine via connecting seats, with each paper tube held between two clamping discs. Existing large-diameter paper tubes are inserted around the large-diameter circular boss for center positioning, while existing small-diameter paper tubes are inserted around the small-diameter circular boss for center positioning. This allows for switching between paper tubes of different diameters without changing the clamping discs, thus improving processing efficiency. During use, only one of the large-diameter or small-diameter paper tubes can be used; both cannot be clamped simultaneously.

[0008] The present invention is further configured such that: a first damping ring is provided on the outer side of the large-diameter circular boss, and the first damping ring is disposed on the base plate; the large-diameter paper tube is inserted into the large-diameter circular boss, and its end abuts against the first damping ring. The friction between the clamping plate and the large-diameter paper tube can be increased by the first damping ring, thereby preventing the large-diameter paper tube from sliding relative to the clamping plate and improving the stability of the large-diameter paper tube during operation.

[0009] A second damping ring is provided on the outer side of the small-diameter circular boss. The second damping ring is set on the large-diameter circular boss. Similarly, the small-diameter paper tube can be inserted into the small-diameter circular boss, and its end can abut against the second damping ring. The second damping ring can increase the friction between the clamp and the small-diameter paper tube, thereby preventing the small-diameter paper tube and the clamp from sliding relative to each other during use and improving the stability of the small-diameter paper tube during operation.

[0010] The present invention is further configured such that: the lower part of the first damping ring is embedded in the base plate, and the upper part of the first damping ring protrudes above the base plate; The lower part of the second damping ring is embedded in the large-diameter circular boss, and the upper part of the second damping ring is higher than the large-diameter circular boss.

[0011] By embedding a portion of the damping ring into the clamping disc body, the connection stability between the damping ring and the clamping disc body can be increased, preventing relative movement between the damping ring and the clamping disc body.

[0012] The present invention is further configured such that: a first wear-resistant ring is embedded on the outer edge of the large-diameter circular boss, and the outer diameter of the first wear-resistant ring is equal to the outer diameter of the large-diameter circular boss; The outer edge of the small-diameter circular boss is fitted with a second wear-resistant ring, and the outer diameter of the second wear-resistant ring is equal to the outer diameter of the small-diameter circular boss.

[0013] The outer walls of the large-diameter and small-diameter round bosses need to be frequently inserted into the corresponding paper tubes, and their outer walls are prone to wear, which affects the center positioning accuracy. By setting the first wear-resistant ring and the second wear-resistant ring, the wear resistance of the outer walls of the large-diameter and small-diameter round bosses can be increased, thereby ensuring the center positioning accuracy of the paper tube.

[0014] This invention is further configured such that the first damping ring, the second damping ring, the first wear-resistant ring, and the second wear-resistant ring are integrally formed. By integrally forming the damping ring and the wear-resistant ring, the placement of the insert, i.e., the integrally formed part, can be facilitated, as can the injection molding production of the clamping plate. At the same time, it can increase the connection stability and positional accuracy between the damping ring and the wear-resistant ring.

[0015] This invention is further configured such that: each of the large-diameter and small-diameter circular bosses has an annular groove formed on its outer wall, and a rubber ring is fitted inside the annular groove, with the rubber ring slightly higher than the outer wall of the corresponding circular boss. After the paper tube is inserted into the corresponding circular boss, the outer wall of the rubber ring presses against the inner wall of the paper tube, thereby creating friction between the circular boss and the paper tube, further preventing relative sliding between the clamp and the paper tube, and further improving the stability of the paper tube during operation.

[0016] The present invention is further configured such that: a groove is formed in the middle of the small-diameter circular boss, and a plurality of evenly distributed insertion holes are formed on the groove; The settling groove is fitted with a detachable third positioning plate. The third positioning plate includes an integrally formed third circular boss, a base plate, and multiple evenly distributed pins. The pins are inserted into corresponding holes. The third circular boss is coaxially arranged with the large-diameter circular boss.

[0017] When using unconventional paper tubes, insert the pin of the third positioning plate into the insertion hole to connect the third positioning plate to the clamping plate body. Then, insert the unconventional paper tube onto the third positioning plate to complete the clamping operation. For clamping unconventional paper tubes, only a small component needs to be added, eliminating the need for an additional clamping plate of the corresponding specifications, thus reducing production costs.

[0018] This invention is further configured such that the outer diameter of the third circular boss has multiple specifications. Since the inner diameters of unconventional paper tubes vary, the third circular boss is configured with multiple specifications to accommodate paper tubes of different sizes.

[0019] The outstanding effect of this utility model is: Compared with existing technologies, the design of large-diameter and small-diameter round bosses can directly adapt to paper tubes with standard inner diameters such as 69mm and 53mm, without the need to change the clamping plate, thus improving production efficiency.

[0020] The damping ring and rubber ring increase the friction between the clamp and the paper tube, preventing relative slippage; the wear-resistant ring ensures the positioning accuracy of the round boss and extends the service life of the clamp.

[0021] With its detachable third positioning plate, it can be adapted to various non-standard paper tubes without the need for custom-made clamps, reducing production costs and providing good scalability.

[0022] The damping ring and wear-resistant ring are integrally molded, which simplifies the production process and improves the stability of component connections. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] The following is for reference Figures 1 to 5 The present invention will be described as follows: Example 1 An improved paper tube clamp, as shown in Figures 1 and 2, includes a clamp body 1. One side of the clamp body 1 is formed with a base plate 11, a large-diameter circular boss 12 and a small-diameter circular boss 13 arranged coaxially. The large-diameter circular boss 12 connects the base plate 11 and the small-diameter circular boss 13. The other side of the clamp body 1 is formed with a connecting seat 14. In use, the clamp body 1 is connected to the corresponding component of the texturing machine via the connecting seat 14, and each paper tube is clamped between two clamps. Existing large-diameter paper tubes are inserted around the large-diameter circular boss 12 for center positioning, while existing small-diameter paper tubes are inserted around the small-diameter circular boss 13 for center positioning. This allows for switching between paper tubes of different diameters without changing the clamps, thus improving processing efficiency. During use, only one of the large-diameter or small-diameter paper tubes can be used; both cannot be clamped simultaneously. A first damping ring 15 is provided on the outer side of the large-diameter circular boss 12, and the first damping ring 15 is disposed on the base plate 11. The large-diameter paper tube is inserted into the large-diameter circular boss 12, and its end abuts against the first damping ring 15. The first damping ring 15 can increase the friction between the clamping plate and the large-diameter paper tube, thereby preventing the large-diameter paper tube from sliding relative to the clamping plate and improving the stability of the large-diameter paper tube during operation. A second damping ring 16 is provided on the outer side of the small-diameter circular boss 13. The second damping ring 16 is provided on the large-diameter circular boss 12. Similarly, the small-diameter paper tube can be inserted into the small-diameter circular boss 13, and its end can abut against the second damping ring 16. The second damping ring 16 can increase the friction between the clamp and the small-diameter paper tube, thereby preventing the small-diameter paper tube and the clamp from sliding relative to each other during use and improving the stability of the small-diameter paper tube during operation. Example 2 Based on Embodiment 1, as shown in Figure 3, the lower part of the first damping ring 15 is embedded in the base plate 11, and the upper part of the first damping ring 15 protrudes above the base plate 11. The lower part of the second damping ring 16 is embedded in the large-diameter circular boss 12, and the upper part of the second damping ring 16 is higher than the large-diameter circular boss 12. By embedding a portion of the damping ring into the clamping plate body 1, the connection stability between the damping ring and the clamping plate body 1 can be increased, preventing relative movement between the damping ring and the clamping plate body 1. The outer edge of the large-diameter circular boss 12 is fitted with a first wear-resistant ring 17, and the outer diameter of the first wear-resistant ring 17 is equal to the outer diameter of the large-diameter circular boss 12. The outer edge of the small-diameter circular boss 13 is fitted with a second wear-resistant ring 18, and the outer diameter of the second wear-resistant ring 18 is equal to the outer diameter of the small-diameter circular boss 13. The outer walls of the large-diameter circular boss 12 and the small-diameter circular boss 13 need to be frequently inserted into the corresponding paper tubes, and their outer walls are prone to wear, which affects the center positioning accuracy. By setting the first wear-resistant ring 17 and the second wear-resistant ring 18, the wear resistance of the outer walls of the large-diameter circular boss 12 and the small-diameter circular boss 13 can be increased, thereby ensuring the center positioning accuracy of the paper tube. The first damping ring 15, the second damping ring 16, the first wear-resistant ring 17, and the second wear-resistant ring 18 are integrally formed. By integrally forming the damping ring and the wear-resistant ring, the placement of the insert, i.e., the integrally formed part, can be facilitated, as can the injection molding production of the clamping plate. At the same time, the connection stability and positional accuracy between the damping ring and the wear-resistant ring can be increased. Example 3 Based on Example 1, as shown in Figure 4, annular grooves 19 are formed on the outer walls of both the large-diameter circular boss 12 and the small-diameter circular boss 13. A rubber ring 2 is fitted inside the annular groove 19, and the rubber ring 2 is slightly higher than the outer wall of the corresponding circular boss. After the paper tube is inserted into the corresponding circular boss, the outer wall of the rubber ring 2 presses against the inner wall of the paper tube, thereby creating friction between the circular boss and the paper tube. This further prevents relative sliding between the clamp and the paper tube, and further improves the stability of the paper tube during operation. Example 4 Based on Example 1, as shown in Figure 5, a groove 110 is formed in the middle of the small-diameter round boss 13, and a plurality of evenly distributed insertion holes 111 are formed on the groove 110. The recess 110 is fitted with a detachable third positioning plate 3. The third positioning plate 3 includes an integrally formed third circular boss 31, a base plate 32 and a plurality of evenly distributed pins 33. The pins 33 are inserted into the corresponding insertion holes 111. The third circular boss 31 is coaxially arranged with the large-diameter circular boss 12. When unconventional paper tubes are needed, the pin 33 of the third positioning plate 3 is inserted into the insertion hole 111, thereby connecting the third positioning plate 3 and the clamping plate body 1 as a whole. Then, the unconventional paper tube is inserted into the third positioning plate 3, thus completing the clamping work of the unconventional paper tube. For the clamping work of unconventional paper tubes, only a small component needs to be added, without the need to open an additional clamping plate of the corresponding specifications, which can reduce production costs. The outer diameter of the third circular boss 31 is available in various specifications. Since the inner diameter of unconventional paper tubes varies, the third circular boss 31 is configured with various specifications to accommodate paper tubes of different sizes.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
