Description

Technical Field

[0001] This invention relates to the field of yarn guiding devices, specifically a yarn guiding device for the production of polyester low-elasticity yarn. Background Technology

[0002] In patent application CN220723171U, a base plate is included. A pay-off roller, a guide roller, a winding device, and a take-up roller are fixedly connected to the top of the base plate. An adjustment device is provided on one side of the outer surface of the guide roller. By providing the adjustment device, when the guide roller of the yarn guiding device cannot guide polyester yarns of different diameters, the yarn guiding device often becomes functionally limited and cannot be adjusted to meet actual needs. The threaded rod of the adjustment device can adjust the length of the guide roller shaft by turning it. At the same time, the telescopic plate can stretch the adjustment shaft and the guide roller shaft to increase the length of the guide roller shaft, so that the guide roller shaft can adapt to more polyester yarns of different diameters and achieve the guiding function.

[0003] In the aforementioned patents, the replacement process of the guide wheel fixing structure in some existing equipment is time-consuming and labor-intensive, increasing the labor intensity of operators and affecting the continuous operation efficiency of the production line. In addition, during the production of polyester low-elasticity yarn, the high-speed running yarn bundles are prone to accumulating fiber dust, oil and other impurities on the surface of the guide wheels. If these contaminants are not removed in time, they will not only increase the frictional damage to the yarn bundles, leading to yarn bundle tension fluctuations and a decline in surface quality, but may also cause yarn bundle skipping, delamination or even yarn breakage due to the adhesion of impurities, affecting the stability of production and the quality of the finished yarn.

The motor output end of the second motor passes through the horizontal plate and is fixedly connected to a threaded rod, which is threadedly connected to the second connecting horizontal plate.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) This application achieves fixation by inserting the first sliding rod and the second sliding rod into the slots on both sides of the guide wheel. The normal extension state of the rod is maintained by the elastic force of the first spring and the second spring. When it is necessary to replace the worn or different specifications of the guide wheel, the operator only needs to start the external air pump equipment connected to the connecting pipe to pump air. The negative pressure airflow will flow along the connecting pipe and the ventilation pipe in the bottom plate, then through the connecting pipe in the support rod and the fixed ring, the connecting hole on the first fixed component, and finally into the mounting slot in the fixed column and the mounting cavity in the connecting column. The negative pressure acts on the first sealing partition and the second sealing partition at the same time, generating a suction force that overcomes the force of the spring, pulling the first sliding rod and the second sliding rod back into the rotating column or the connecting column, so that the guide wheel is unlocked. The old guide wheel can be quickly removed and replaced with a new guide wheel. Then the air pump is turned off and the vacuum is released. Each rod automatically extends under the action of the spring force and inserts into the slot of the new guide wheel to complete the locking. This shortens the downtime for replacement, reduces the difficulty of operation and labor intensity, and improves the continuous operation capability of the production line. (2) In this application, a cleaning mechanism is set between every two sets of support rods. A cleaning wiper with a matching shape is arranged directly below each guide wheel, and the cleaning wiper is fixed on the sliding block above. When the first drive assembly drives all three sets of guide wheels to rotate synchronously to guide and transport the polyester low-elasticity yarn, the outer circumferential surface of the guide wheel continuously contacts the cleaning wiper below. The cleaning wiper can wipe away the fiber dust, oil stains and electrostatic adsorption impurities accumulated on the surface of the guide wheel due to long-term operation in real time, avoiding these contaminants from causing frictional damage to the polyester low-elasticity yarn or causing fluctuations in yarn tension, ensuring that the yarn surface is smooth and the color is uniform, and significantly improving the quality of the finished yarn. The second drive assembly... The second motor in the moving assembly drives the second connecting plate and the U-shaped connecting frame to move as a whole through the threaded rod, thereby driving all the U-shaped fixed frames to slide along the second sliding groove. This causes the rotating rod and rubber ring on the U-shaped fixed frame to press against the upper sides of the guide wheel. During the rotation of the guide wheel, the rubber ring drives the rotating rod to rotate by friction, effectively preventing wire skipping, derailment, or wire tangling during high-speed wire guiding. This ensures that the wire bundle always runs smoothly within the predetermined groove of the guide wheel. When the equipment stops running, the second motor reverses to move the rubber ring away from the guide wheel, making it easier to clean or replace the guide wheel. This reduces the frequency of manual shutdown for cleaning and avoids wire breakage or entanglement caused by wire bundle jumping. Attached Figure Description

The threaded rod 332 is threadedly connected to the second connecting horizontal plate 322.

[0031] The working principle of the present invention is as follows: When the equipment is in normal production, the external air pump is not working and the air circuit of the entire device is in a normal pressure state. At this time, the first sliding rod 252 and the second sliding rod 284 maintain the tendency to extend outward under the action of the first spring 245 and the second spring 287. The head of the rod is inserted into the slot 42 on both sides of the guide wheel 41, locking the guide wheel on the rotating component 28 or the connecting component 25 to achieve fixation. When the guide wheel needs to be replaced, the equipment is stopped. The external air pump is started, and air is drawn in through the connecting pipe 14. The negative pressure airflow is transmitted through the following path: external air pump, connecting pipe 14, connecting pipe 12 in the base plate 11, each ventilation pipe 13, connecting pipe 263 in the support rod 261 and the fixing ring 262, connecting hole 274 on the first fixing component 27, and mounting through groove 272 in the fixing column 271. At the same time, the gas is drawn from the connecting column 251 through the connecting pipe 263. Negative pressure reaches the first sliding groove 283 inside the rotating column 281, acting on the second sealing partition 285 to generate suction, overcoming the force of the second spring 287 and pulling the second sliding rod 284 completely back into the rotating column 281. Similarly, negative pressure also acts on the first sealing partition 253 through the passage in the connecting column 251, overcoming the elastic force of the first spring 245 and pulling the first sliding rod 252 back. When all the rods have retracted from the slot 42 of the guide wheel 41, the guide wheel 41 is unlocked and can be directly removed and replaced. After replacing the new guide wheel 41, the air pump stops working and releases the vacuum, restoring normal pressure in the air circuit. At this time, the forces of the second spring 287 and the first spring 245 are restored, automatically pushing out the first sliding rod 252 and the second sliding rod 284 and inserting them into the slot 42 of the new guide wheel 41, completing the locking without any manual operation. The first motor 241 in the first drive assembly 24 starts, driving the square short rod 243, the rotating short rod 242 and the fixed plate 244 to rotate. The square short rod 243 drives the first sliding rod 252 to rotate through the sliding short groove on the first sliding rod 252. The first sliding rod 252 drives the first set of guide wheels 41 to rotate through the slot 42. The other end of the first set of guide wheels drives a second sliding rod 284 on the third set of support assemblies 26 to rotate through the slot 42. The second sliding rod 284 is slidably connected to the rotating column 281, thereby driving the rotating column 281 to rotate. Inside the fixed columns 271 of the third and fourth groups, the two rotating columns 281 are fixedly connected by multiple connecting short rods 22. Therefore, the rotation of one rotating column 281 will be transmitted to the other rotating column 281 in the same fixed column 271. The torque is transmitted to the other rotating column through the connecting short rods 22, driving the second sliding rod 284 on it to rotate, thereby driving the next group of guide wheels 41 to rotate. In this way, the power can drive the second and third groups of guide wheels 41 in sequence, realizing the synchronous rotation of all three groups of guide wheels 41, and completing the guiding and conveying of polyester low elastic yarn. The cleaning wiper 316 is located below the guide wheel 41. When the guide wheel 41 rotates, the cleaning wiper 316 automatically cleans the guide wheel 41. Before operation, the second motor 331 is started to drive the threaded rod 332 to rotate. Since the second connecting cross plate 322 fitted with the threaded rod 332 is fixed on the entire U-shaped connecting frame 321, the U-shaped connecting frame 321 and the connected extrusion assembly 34 are driven to move downward synchronously. The movement of the U-shaped connecting frame 321 drives all the U-shaped fixing frames 341 to move along the second sliding through grooves 313 on the first connecting cross plate 312. The rotating rod 343 and the rubber ring 344 on the U-shaped fixing frame 341 move accordingly, and the rubber ring 344 presses against the two sides of the upper part of the guide wheel 41. When the guide wheel 41 rotates, the rotating rod 343 is driven to rotate by the rubber ring 344, so as to prevent the polyester low-elasticity yarn from jumping. When the operation stops, the second motor 331 reverses to drive the rotating rod 343 and the rubber ring 344 to move away from the guide wheel 41.
