Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cotton yarn winding guide devices, and in particular to an anti-tangling cotton yarn winding guide device. Background Technology
[0002] The cotton yarn winding guide device is mainly used to evenly wind cotton yarn onto the bobbin, improve the utilization rate of the bobbin, and ensure the quality and efficiency of cotton yarn winding. It mainly consists of a drive motor moving rod and a guide block. The cotton yarn first passes through the guide block, and the movement of the guide block drives the cotton yarn to move laterally during winding.
[0003] When using a guiding device to guide cotton yarn, if the cotton yarn feeding equipment is unstable during operation or if the cotton yarn surface is covered with lint, causing a brief obstruction when entering the guide block and generating a pulling force on the entire cotton yarn, the surface of the cotton yarn will be in a taut state. This can cause the cotton yarn to break easily during the movement of the guide block, affecting the stability of the guiding device during use. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that when cotton yarn unwinding equipment is unstable during operation or when the surface of the cotton yarn is covered with lint, it is temporarily blocked when entering the guide block, which causes a pulling force on the entire cotton yarn. As a result, part of the surface of the cotton yarn is in a tense state, which makes the cotton yarn prone to breakage during the movement of the guide block and affects the stability of the guide device. Therefore, an anti-tangling cotton yarn winding guide device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tangle cotton yarn winding guide device, comprising a frame plate, a through hole at the top of the frame plate, an electric push rod on one side of the frame plate, a slide rod installed at the output end of the electric push rod, the slide rod sliding on the outer surface of the frame plate, two guide blocks fixedly connected to the top of the slide rod, and a buffer device provided at one end of the guide block to buffer the tensile force on the cotton yarn entering the guide block.
[0006] The effect achieved by the above components is as follows: When using the cotton yarn winding guide device, the end of the cotton yarn entering the winding roller passes through the through hole at the top of the frame plate and through the guide block at the top of the slide rod before being fixed on the winding roller of the cotton yarn. When the cotton yarn is wound by the winding equipment, the electric push rod on one side of the frame plate is controlled to operate. The output rod of the electric push rod drives the slide rod to move back and forth on the outer surface of the frame plate, so that the cotton yarn moves horizontally with the guide block and can be evenly wound on the winding roller of the winding equipment without tangling.
[0007] Preferably, the buffer device includes two support rods, the top of the support rods is fixedly connected to one side of the guide block, the bottom of the support rods is rotatably connected to a rotating shaft, a stop block is fixedly connected to the outer surface of the rotating shaft, the top of the stop block is provided with a through groove, and a torsion spring is provided at one end of the rotating shaft, with the two ends of the torsion spring being fixedly connected to one side of the rotating shaft and one side of the support rod, respectively.
[0008] The effect achieved by the above components is as follows: By setting the stop, when using the guide device, the end of the cotton yarn entering the winding device passes through the guide block and through the through groove on the outer surface of the stop. When the cotton yarn gets stuck during the winding process, causing a sudden force, the end of the cotton yarn that is close to the winding device will generate a pulling force, which will pull the stop on one side of the guide block to rotate downward through the rotating shaft and deform the torsion spring. This will change the downward movement path of the cotton yarn, shorten the distance between the cotton yarn feeding device and the winding device through the guide block, and buffer the pulling force on the cotton yarn. When the external force disappears, the cotton yarn resumes normal movement, and the torsion spring returns to its original state, which will drive the rotating shaft and the stop to rotate back to their original position.
[0009] Preferably, an auxiliary edge is provided on one side of the inner wall of the through groove, and the inner edge of the auxiliary edge is inclined and forms a certain angle with the stop block.
[0010] The effect achieved by the above components is that by setting the auxiliary edge, the cotton yarn will be more likely to push the stop block to rotate downward when it is under force, and the arc edge inside the auxiliary edge will not easily cause wear to the surface of the cotton yarn.
[0011] Preferably, a stop bar is fixedly connected to one side of the support rod, and the stop bar is located above the rotating shaft.
[0012] The effect achieved by the above components is that by setting a stop lever, the movement of the rotating shaft and the stop block when the torsion spring recovers its deformation can be buffered, so that the stop block will not rotate in the expected opposite direction.
[0013] Preferably, one side of one of the support rods is provided with a plurality of threaded holes, and the inner wall of the threaded holes is threaded with bolts.
[0014] The effect achieved by the above components is that when using the buffer device, bolts can be screwed into different threaded holes on one side of the support rod to block the bottom of the stop block and limit and adjust the maximum rotation distance of the stop block.
[0015] Preferably, a plurality of cylinders are fixedly connected to one side of the support rod, and the inner diameter of the cylinders is adapted to the diameter of the bolts.
[0016] The effect achieved by the above components is that when the bolt passes through the threaded hole, the outer surface of the bolt will be located inside the cylinder. The cylinder can support and reinforce the bolt, making it less likely for the bolt to deviate when the stop block contacts the bolt.
[0017] Preferably, the top of the shelf is provided with an auxiliary device, which includes a frame rod, plastic sheets are fixedly connected to both sides of the inner wall of the frame rod, and locking blocks are fixedly connected to both ends of the frame rod. The top of the shelf has two slots, which are located at both ends of the through hole.
[0018] The effect achieved by the above components is as follows: When using the guide device, the locking blocks at both ends of the frame rod can be inserted into the two slots at the top of the frame plate, and the frame rod can be installed in the through hole. The cotton yarn at the plastic sheet on both sides of the inner wall of the frame rod will generate static electricity when it comes into contact with the surface of the plastic sheet. The static electricity can attract the fluff on the surface of the cotton yarn to the plastic sheet.
[0019] Preferably, auxiliary grooves are provided on both sides of the top of the card block, and the internal shape of the auxiliary grooves is semi-circular.
[0020] The effect achieved by the above components is that by pinching the two semi-circular auxiliary grooves on the outer surface of the card block, it is easier to control the card block to be pulled out from the inside of the slot, remove the frame rod, and clean the lint on the surface of the frame rod.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a buffer device, one end of the cotton yarn entering the winding device passes through the through groove on the outer surface of the stop block. When the cotton yarn is subjected to tension during the winding process, the stop block rotates through the shaft, shortening the distance the cotton yarn is released through the unwinding device and enters the winding device. This provides the cotton yarn with a certain buffer space, minimizing the risk of the cotton yarn being subjected to excessive tension, which could cause the surface to become too tight and break.

Detailed Implementation
[0029] Example 1, such as Figure 1-2 As shown, the anti-tangling cotton yarn winding guide device includes a frame plate 1. The top of the frame plate 1 has a through hole 4. An electric push rod 5 is provided on one side of the frame plate 1. A slide rod 6 is installed at the output end of the electric push rod 5. The slide rod 6 slides on the outer surface of the frame plate 1. Two guide blocks 7 are fixedly connected to the top of the slide rod 6. A buffer device 2 is provided at one end of the guide block 7 to buffer the tension force on the cotton yarn entering the guide block 7. When using the cotton yarn winding guide device, the end of the cotton yarn entering the winding roller passes through the through hole 4 at the top of the frame plate 1 and through the guide block 7 at the top of the slide rod 6 before being fixed on the winding roller of the cotton yarn. When the cotton yarn is wound by the winding equipment, the electric push rod 5 on one side of the frame plate 1 is controlled to operate. The output rod of the electric push rod 5 drives the slide rod 6 to move back and forth on the outer surface of the frame plate 1, so that the cotton yarn moves horizontally with the guide block 7 and can be evenly wound on the winding roller of the winding equipment, making it less likely to tangle.
[0030] Reference Figure 1-4As shown in this embodiment: the buffer device 2 includes two support rods 21. The top end of the support rod 21 is fixedly connected to one side of the guide block 7. The bottom end of the support rod 21 is rotatably connected to a rotating shaft 22. A stop block 24 is fixedly connected to the outer surface of the rotating shaft 22. A through groove 25 is opened at the top end of the stop block 24. A torsion spring 23 is provided at one end of the rotating shaft 22. The two ends of the torsion spring 23 are fixedly connected to one side of the rotating shaft 22 and one side of the support rod 21, respectively. By setting the stop block 24, when using the guiding device, the end of the cotton yarn entering the winding device passes through the guide block 7 and through the through groove 25 on the outer surface of the stop block 24. When the cotton yarn gets stuck during the winding process, causing a sudden force, the end of the cotton yarn close to the winding device will generate a pulling force, pulling the stop block 24 on one side of the guide block 7 to rotate downward through the rotating shaft 22. The torsion spring 23 deforms, causing the cotton yarn to move downwards, thus shortening the distance between the cotton yarn feeding device and the winding device via the guide block 7. This buffers the tensile force on the cotton yarn. When the external force disappears, the cotton yarn resumes normal movement, and the torsion spring 23 returns to its original shape, causing the rotating shaft 22 and the stop block 24 to rotate back to their original positions. By setting the buffer device 2, and by having one end of the cotton yarn entering the winding device pass through the through groove 25 on the outer surface of the stop block 24, the stop block 24 rotates via the rotating shaft 22 when the cotton yarn is subjected to tensile force during winding, shortening the distance the cotton yarn travels from the feeding device to the winding device. This provides the cotton yarn with a certain buffer space, minimizing the risk of the cotton yarn being subjected to excessive tensile force, which could cause the surface to become too tight and break.
[0031] Reference Figure 2-4 As shown in this embodiment: an auxiliary edge 26 is provided on one side of the inner wall of the through groove 25. The inner edge of the auxiliary edge 26 is inclined and forms a certain angle with the stop block 24. By setting the auxiliary edge 26, it is easier for the cotton yarn to push the stop block 24 to rotate downward when it is under force. Moreover, the arc-shaped edge inside the auxiliary edge 26 is less likely to cause wear on the surface of the cotton yarn. A stop rod 27 is fixedly connected to one side of the support rod 21. The stop rod 27 is located above the rotating shaft 22. By setting the stop rod 27, the movement position of the rotating shaft 22 and the stop block 24 when the torsion spring 23 recovers its deformation can be buffered, so that the stop block 24 will not rotate in the expected opposite direction.
[0032] Reference Figure 2-4As shown in this embodiment: a support rod 21 has several threaded holes 28 on one side, and bolts 29 are threadedly connected to the inner wall of the threaded holes 28. When using the buffer device 2, the bolts 29 can be screwed into different positions of the threaded holes 28 on one side of the support rod 21. The bolts 29 block the bottom of the stop block 24 and limit the maximum rotation distance of the stop block 24. A number of cylinders 210 are fixedly connected to one side of the support rod 21. The inner diameter of the cylinders 210 is matched with the diameter of the bolts 29. When the bolts 29 pass through the threaded holes 28, the outer surface of the bolts 29 will be located inside the cylinders 210. The cylinders 210 can support and reinforce the bolts 29, so that the bolts 29 are not prone to deflection when the stop block 24 contacts the bolts 29.
[0033] Reference Figure 1 , Figure 2 and Figure 5 As shown in this embodiment: an auxiliary device 3 is provided at the top of the shelf 1. The auxiliary device 3 includes a frame rod 32. Plastic sheets 34 are fixedly connected to both sides of the inner wall of the frame rod 32. Locking blocks 33 are fixedly connected to both ends of the frame rod 32. Two slots 31 are opened at the top of the shelf 1, located at both ends of the through hole 4. When using the guiding device, the locking blocks 33 at both ends of the frame rod 32 can be inserted into the two slots 31 at the top of the shelf 1, thus installing the frame rod 32 into the through hole 4. When the cotton yarn at the plastic sheet 34 on both sides of the inner wall of the frame rod 32 comes into contact with the surface of the plastic sheet 34, static electricity is generated. The static electricity can attract the lint on the surface of the cotton yarn to the plastic sheet 34. The top of the locking block 33 has auxiliary grooves 35 on both sides. The internal shape of the auxiliary grooves 35 is semi-circular. By pinching the two semi-circular auxiliary grooves 35 on the outer surface of the locking block 33, it is easier to grasp the locking block 33 and control the locking block 33 to be pulled out from the inside of the slot 31 to remove the frame rod 32 and clean the lint on the surface of the frame rod 32.
[0034] Working principle: When using the cotton yarn winding guide device, first insert the locking blocks 33 at both ends of the frame rod 32 into the two slots 31 at the top of the frame plate 1. Install the frame rod 32 in the through hole 4. The end of the cotton yarn entering the winding roller passes through the through hole 4 at the top of the frame plate 1 and through the guide block 7 at the top of the slide rod 6. Then, it passes through the through groove 25 on the outer surface of the stop block 24 and is fixed on the winding roller of the cotton yarn. When the cotton yarn is wound by the winding equipment, the electric push rod 5 on one side of the frame plate 1 is controlled to operate. The output rod of the electric push rod 5 drives the slide rod 6 to move back and forth on the outer surface of the frame plate 1, so that the cotton yarn moves horizontally with the guide block 7 and can be evenly wound on the winding roller of the winding equipment without tangling. When the cotton yarn passes through the plastic sheets 34 on both sides of the inner wall of the frame rod 32, static electricity is generated when the cotton yarn comes into contact with the surface of the plastic sheets 34. The static electricity can attract the lint on the surface of the cotton yarn to the plastic sheets 34. When the cotton yarn gets stuck during the winding process, causing a sudden force, the end of the cotton yarn that is close to the winding device will generate a pulling force, which will pull the stop block 24 on one side of the guide block 7 to rotate downward through the rotating shaft 22 and deform the torsion spring 23. This changes the downward movement path of the cotton yarn, shortens the distance between the cotton yarn feeding device and the winding device through the guide block 7, and buffers the pulling force on the cotton yarn. When the external force disappears, the cotton yarn resumes normal movement, and the torsion spring 23 returns to its original shape, which will drive the rotating shaft 22 and the stop block 24 to rotate back to their original positions.
