Description

Technical Field

[0001] This utility model relates to the field of polyester production technology, and in particular to a tool for drawing and passing through polyester filament holes. Background Technology

[0002] In the production of polyester filament, volatile substances such as monomers or low-molecular-weight polymers are generated during spinning. In indirect spinning, this is generally around 2%, while in direct spinning it is slightly higher, with monomer and low-molecular-weight polymer content reaching 10%. The volatile monomers and low-molecular-weight polymers contaminate the spinneret surface, affecting the quality of the spun filaments, causing increased filament breakage and reducing the number of times the spinneret is cleaned, while also impacting the working environment at the spinning site.

[0003] In polyester filament production, a single winding machine has 24 heads, resulting in a large number of fibers per spinning station and a high extrusion rate. This leads to the release of more monomers and low-molecular-weight polymers during spinning. Therefore, using a monomer suction device is essential. This device utilizes the chimney effect to remove oligomers generated during spinning, improving workability, reducing yarn breakage, increasing the number of board cleaning passes, and lowering production costs. However, due to the constraints of the spinning environment, the suction tube is generally small, making it impossible to completely remove all the oligomers using the chimney effect. A large amount of oligomers adheres to the tube wall, which can easily cause blockage over time, resulting in uneven dyeing. Manual removal of the oligomers from the suction tube using tools is necessary. Commonly used tools include specially designed brushes and electric drills with custom-made bits. The brush bristles remove the oligomers, while the electric drill uses a cross-shaped thread on a special drill bit to extract them. The drill bit must be custom-made to fit the size of the suction tube.

[0004] However, existing hole-clearing tools have the following drawbacks: Manual hole clearing with a brush requires a significant amount of manpower; typically, clearing one 24-hole section takes a single employee 20 minutes. Furthermore, the quality of the hole clearing is uncontrollable and susceptible to human error. If the pipe is blocked by oligomers, it cannot be handled, requiring maintenance to dismantle the pipe, impacting production stoppage and drainage efficiency. After clearing, an air gun is needed to blow out the oligomers, adding to the operational steps and increasing employee fatigue. While electric drills can penetrate deep into pipes with relatively simple drill bits (usually triangular and cross-shaped), they are less effective at removing oligomers adhering to the pipe wall compared to a brush. The drill bit can also easily get stuck in the pipe, causing damage to both the drill bit and the pipe. Additionally, the high-speed rotation of the drill during hole clearing causes oligomers to splatter, affecting the hygiene of the spinning area and posing a safety hazard as the hot oligomers can splash onto employees. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention

[0005] In view of the above shortcomings, the purpose of this utility model is to provide a polyester filament suction and hole-opening tool to solve the problems of oligomers adhering to the pipe wall, which are difficult to completely remove manually, resulting in low hole-opening efficiency, and easy overheating and pipe jamming when using electric drill bits.

[0006] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows:

[0007] A polyester filament suction and through-hole tool, characterized in that it includes a housing and a handle mounted on the housing, a hollow tube rotatably passing through the housing, a first end of the hollow tube being detachably connected to an air tube, a bristle being installed at the free end of the air tube, a second end of the hollow tube being used to connect to a pipeline, and a drive motor being installed inside the housing, the drive motor being connected to the hollow tube through a reduction gear structure.

[0008] As a preferred technical solution, a sealing ring is fitted onto the second end of the hollow tube.

[0009] As a preferred technical solution, a one-way valve is installed at the second end of the hollow tube.

[0010] As a preferred technical solution, the deceleration structure includes a linkage shaft rotatably installed inside the housing, a first pinion and a first large gear mounted on the linkage shaft, a second pinion connected to the output shaft of the drive motor, the second pinion meshing with the first large gear, and a second large gear sleeved on the hollow tube, the first pinion and the second large gear meshing with each other.

[0011] As a preferred technical solution, the handle is hinged to the outer shell by bolts.

[0012] As a preferred technical solution, a positioning ring is installed at the end of the trachea, and an insertion ring is installed on one side of the positioning ring. An outer ring is constructed on the outer periphery of the first end of the hollow tube. The insertion ring is inserted into the outer ring, and the positioning ring abuts against the outside of the outer ring. An elastic telescopic insertion rod is hinged on the outer ring, and an insertion hole is constructed on the outer ring. The elastic telescopic insertion rod passes over the outer ring and is inserted into the insertion hole.

[0013] As a preferred technical solution, a sealing gasket is connected inside the outer ring by a compression spring, and the sealing gasket fits into the insert ring.

[0014] Compared with traditional technical solutions, the beneficial effects of this utility model are:

[0015] 1) Driving the brush head with a drive motor can improve the efficiency of through-hole operation and reduce manpower;

[0016] 2) Because the bristles are soft and easily deformable, they can pass smoothly through the tube wall, effectively preventing tools from getting stuck in the suction tube;

[0017] 3) While brushing off the oligomers with bristles, the oligomers are blown out using an air tube. This saves time compared to the traditional method of opening the holes first and then blowing out with compressed air.

[0018] 4) The brush bristles are driven by a drive motor, resulting in a good cleaning effect. The brush can clean every part of the pipe wall. Attached Figure Description

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] Please refer to Figures 1-6 This utility model provides a polyester filament suction and through-hole tool, including a housing 1 and a handle 2 mounted on the housing 1. The handle 2 is equipped with a switch button, a lithium battery, a control panel, and a plug for charging the lithium battery. A hollow tube 3 rotatably passes through the housing 1. The first end of the hollow tube 3 is detachably connected to an air pipe 6. Brush bristles 7 are installed at the free end of the air pipe 6. The second end of the hollow tube 3 is used to connect to a pipeline. Compressed air is supplied into the hollow tube 3 through the pipeline, and then discharged through the air pipe 6. A drive motor 4 is installed inside the housing 1, wherein the lithium battery serves as the drive motor 4. The power supply is provided by the drive motor 4, which is connected to the hollow tube 3 via a reduction structure 5. The speed of the hollow tube 3 is reduced by the reduction motor, thereby reducing the speed of the air tube 6 and preventing oligomers from splashing due to high-speed rotation of the air tube 6. In use, the air tube 6 is inserted into the suction tube. The drive motor 4 drives the hollow tube 3 to rotate via the reduction structure 5. The hollow tube 3 drives the air tube 6 to rotate. The bristles 7 at the front end of the air tube 6 come into contact with the oligomers attached to the tube wall and generate friction, thereby removing the oligomers and achieving the cleaning effect of the suction tube. The oligomers brushed off the tube wall by the bristles 7 are blown out by the compressed air in the air tube 6 and carried out of the suction tube.

[0029] The hole-clearing tool of this invention can solve the problems of oligomers adhering to the pipe wall, which are difficult to remove completely manually, resulting in low hole-clearing efficiency and easy overheating and pipe jamming when using an electric drill. It can improve hole-clearing efficiency and thoroughly clean the oligomers in the suction pipe.

[0030] like Figures 3-4 As shown, a sealing ring 8 is fitted on the second end of the hollow tube 3, and a one-way valve 9 is installed on the second end of the hollow tube 3. Considering that the through-hole tool needs to be used throughout the workshop, in order to facilitate connection with compressed air pipelines in various places, the hollow tube 3 is connected to the pipeline by a pipeline sleeve method. The sealing ring 8 is designed to increase the friction and sealing performance at the contact point, ensuring the airtightness and stability of the connection. The one-way valve 9 is designed to prevent impurities from entering the pipeline.

[0031] like Figure 2 As shown, to achieve deceleration of the air tube 6, the deceleration structure 5 includes a linkage shaft 501 rotatably mounted inside the housing 1. A first pinion 502 and a first gear 503 are mounted on the linkage shaft 501. The output shaft of the drive motor 4 is connected to a second pinion 504, which meshes with the first gear 503. A second gear 505 is sleeved on the hollow tube 3, and the first pinion 502 and the second gear 505 mesh with each other. The deceleration structure 5 proposed in this application has two stages. First, with the cooperation of the first gear 503 and the second pinion 504, a first-stage deceleration is achieved, reducing the rotational speed of the linkage shaft 501. Then, with the cooperation of the first pinion 502 and the second gear 505, a second-stage deceleration is achieved, reducing the rotational speed of the hollow tube 3. Finally, the rotational speed of the air tube 6 is reduced, avoiding oligomer splashing.

[0032] like Figure 1 As shown, the handle 2 is tightly hinged to the outer shell 1 by bolts. When the handle 2 is not in use, it can be folded and stored by rotating the handle 2. When in use, it can be rotated and unfolded.

[0033] like Figures 3-6 As shown, a positioning ring 12 is installed at the end of the trachea 6, and an insertion ring 11 is installed on one side of the positioning ring 12. An outer ring 10 is constructed on the outer periphery of the first end of the hollow tube 3. The insertion ring 11 is inserted into the outer ring 10, and the positioning ring 12 abuts against the outside of the outer ring 10. An elastic telescopic insertion rod 13 is hinged on the outer ring 10. An insertion hole 14 is constructed on the outer ring 10. The elastic telescopic insertion rod 13 passes through the outer ring 10 and is inserted into the insertion hole 14. The elastic telescopic insertion rod 13 is composed of a spring, an outer rod, and an inner rod. An area for receiving the insertion ring 11 is formed between the outer ring 10 and the outer periphery of the hollow tube 3. In the chamber of tube 1, when connecting the trachea 6 to the hollow tube 3, the insert ring 11 is inserted into the chamber. The end of the elastic telescopic sleeve has an L-shaped insert block. During the connection of the trachea 6 and the hollow tube 3, the elastic telescopic sleeve is stretched and rotated. After the connection of the trachea 6 and the hollow tube 3 is completed, the angle of the elastic telescopic sleeve is adjusted. At this time, the insert block has passed the positioning ring 12. The insert block is aligned with the insertion hole 14 and inserted into the insertion hole 14. Relying on the spring action on the elastic telescopic sleeve, the positioning ring 12 is limited and tightened, thus completing the quick positioning and connection action of the trachea 6 and the hollow tube 3.

[0034] like Figures 3-6As shown, a sealing gasket 16 is connected inside the outer ring 10 by a compression spring 15. The sealing gasket 16 fits tightly with the insert ring 11. In order to improve the airtightness of the connection between the air tube 6 and the hollow tube 3, the design of compression spring 15 and sealing gasket 16 is added. The sealing gasket 16 fits tightly with the end of the insert ring 11 under the action of compression spring 15. The spring force on the elastic telescopic sleeve is greater than the spring force of compression spring 15.
