Abstract

The utility model relates to the technical field of chemical fiber yarn guide, and discloses a chemical fiber multi-groove yarn guide which comprises a top plate, two pairs of screws used for fixedly installing the top plate are inserted into the lower surface of the top plate, and a yarn guide unit is installed below the top plate. According to the chemical fiber multi-groove yarn guide, through cooperation of the top plate, the base plate and the yarn guide units, when a chemical fiber yarn is dragged to move, the yarn guide groove wheel starts conducting yarn guide operation on the chemical fiber yarn, in the process, if the chemical fiber yarn is subjected to traction acting force to generate transverse force, the acting force can be transmitted to the vertical plate through the yarn guide groove wheel, the circular shaft, the circular rod and the flitch plate, and therefore the chemical fiber yarn is guided. The vertical plate rotates by a certain angle with the disc as the center, and then the yarn guiding grooved wheel is driven to swing in the direction of the deviation acting force of the chemical fiber yarn, so that the probability that the chemical fiber yarn is located in the center of the yarn guiding grooved wheel during conduction can be increased, the probability that the chemical fiber yarn is separated from the yarn guiding grooved wheel is reduced, and stable chemical fiber yarn guiding operation is facilitated.

Description

Technical Field

[0001] This utility model relates to the field of chemical fiber wire guiding technology, specifically a chemical fiber multi-groove wire guide. Background Technology

[0002] The fiber guide is considered the "precision commander" in the chemical fiber production process. It is a key component used to precisely guide, position, and control the movement trajectory of the fiber bundle, firmly placing it among the core functional components of textile machinery. From the high-temperature spinning stage, it guides the direction of the fiber bundle, ensuring its smooth passage through the spinneret. In the stretching and setting stage, it strictly controls the fiber bundle's direction to achieve ideal strength and elasticity. Even in the final winding stage, it continues to stably guide the fiber, preventing tangling and confusion. Its performance directly determines the fiber's uniformity of thickness, breaking strength, and other physical properties, and is crucial to production efficiency and product quality.

[0003] Currently, in order to simultaneously guide multiple strands of synthetic fiber, synthetic fiber guides are equipped with multiple guide rollers for adaptation. Although this method can achieve synchronous guiding of multiple strands of synthetic fiber, during the guiding process, the traction force on the synthetic fiber inevitably causes lateral deviation (for example, during the winding of synthetic fiber). At this time, the synthetic fiber will not be in the center position of the grooved roller. If the lateral traction force on the synthetic fiber is large, the probability of it detaching from the grooved roller will increase significantly, which is not conducive to the stable guiding of synthetic fiber. Utility Model Content

[0004] The purpose of this invention is to provide a multi-groove fiber guide for chemical fibers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-groove fiber guide, comprising: a top plate, with two pairs of screws inserted into the lower surface of the top plate for fixing the top plate; a fiber guide unit installed below the top plate; the fiber guide unit comprising: a base plate, the base plate being fixedly connected to one end of the lower surface of the top plate; a cylinder being rotatably connected to the inner wall of the base plate; a spring being fixedly sleeved at one end of the cylinder; a housing being fixedly connected to the outer ring of the spring; the housing being fixedly connected to the base plate; and the other end of the cylinder being fixedly connected to... A disc is provided, with a pair of vertical plates fitted on both the front and rear sides of the disc. A pair of first bolts are inserted into the surface of the vertical plates away from the disc, and the first bolts penetrate the vertical plates and are threadedly connected to them. A pair of sliders are fixed to the outer wall of the disc, and the sliders are slidably connected to the vertical plates via grooves. Elastic elements are fixed to both sides of the sliders, and the elastic elements are fixedly connected to the vertical plates. Multiple pairs of guide wire groove wheels are installed on the side of the vertical plates away from the substrate, and chemical fiber threads overlap the outer wall of the guide wire groove wheels.

[0006] Preferably, a protruding rod is fixedly connected to the center of both the front and rear surfaces of the disk, and the protruding rod is rotatably connected to the upright plate through a circular groove.

[0007] Preferably, a pair of plates are attached to the surface of the vertical plate away from the substrate. The plates are connected to the vertical plate by a second bolt. A round rod is fixed to the center of the surface of the plates away from the vertical plate. A round shaft is rotatably connected to the outer wall of the round rod. The round shaft has a multi-segment structure, and the multiple segments of the round shaft are threaded together. The outer wall of the multiple segments of the round shaft is clearance-fitted with the outer wall of the guide wire groove wheel. A collar is fixedly sleeved on one end of the outer wall of the round shaft. A pair of third bolts are inserted into the surface of the collar away from the guide wire groove wheel. The third bolts pass through the collar and are threadedly connected to the guide wire groove wheel.

[0008] Preferably, a pair of circular blocks are provided between adjacent guide wire groove wheels, and both ends of the circular blocks are fixedly connected to insert rods, which are connected to the guide wire groove wheels through slots.

[0009] Preferably, a magnetic block is fixed inside the slot, and the magnetic block is magnetically attracted to the insertion rod.

[0010] Preferably, the end of the circular shaft furthest from the vertical plate is threaded with a plug.

[0011] Preferably, the end of the insertion rod away from the circular block has a tapered structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-groove fiber guide has the following advantages:

[0013] Through the cooperation between the top plate, base plate, and guide wire unit, the operator can attach the chemical fiber to be guided to the outer wall of the guide wire groove wheel. When the chemical fiber is pulled and moved, the guide wire groove wheel begins to guide it. During this process, if the traction force on the chemical fiber is transverse, the force will be transmitted to the vertical plate through the guide wire groove wheel, the round shaft, the round rod, and the plate, causing the vertical plate to rotate at a certain angle around the disc. This will cause the guide wire groove wheel to swing in the direction of the chemical fiber offset force. This increases the probability that the chemical fiber is at the center of the guide wire groove wheel during the transmission process and reduces the probability that the chemical fiber will detach from the guide wire groove wheel, which is conducive to the stable operation of guiding the chemical fiber.

[0014] Through the cooperation between the top plate, the base plate, and the guide wire unit, during the transmission process of the chemical fiber wire, the chemical fiber wire applies a certain force to the guide wire groove wheel, causing the upper and lower guide wire groove wheels to revolve around the cylinder. During this period, the cylinder will rotate at a certain angle according to the intensity of the force applied by the chemical fiber wire to the guide wire groove wheel. At the same time, the mainspring will undergo a certain degree of compression deformation. The elastic potential energy generated by the compression deformation of the mainspring will cause the guide wire groove wheel to generate a force opposite to the direction of the force applied by the chemical fiber wire, thereby providing tension for the transmission of the chemical fiber wire and facilitating high-quality transmission of the chemical fiber wire.

[0015] Through the cooperation between the top plate, base plate and wire guide unit, and because the round shaft adopts a detachable segmented structure, and each segment of the round shaft is equipped with a wire guide groove wheel on its outer side, and adjacent wire guide groove wheels can be connected by insert rods and slot structures, the number of wire guide groove wheels can be increased or decreased according to actual production and processing needs to meet different processing requirements and expand its application range.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a multi-groove fiber guide, comprising: a top plate 1, with two pairs of screws inserted into the lower surface of the top plate 1 for fixing the top plate 1; a fiber guide unit installed below the top plate 1, the fiber guide unit comprising: a base plate 2, the base plate 2 being fixedly connected to one end of the lower surface of the top plate 1; a cylinder 3 being rotatably connected to the inner wall of the base plate 2; a spring 4 being fixedly sleeved at one end of the cylinder 3; a housing 5 being fixedly connected to the outer ring of the spring 4; the housing 5 being fixedly connected to the base plate 2; and a disc 7 being fixedly connected to the other end of the cylinder 3; the disc 7 having two... Each side is fitted with a pair of vertical plates 6. The front and rear sides of the disc 7 are provided with vertical plates 8. A pair of first bolts 9 are inserted into the surface of the vertical plate 8 away from the disc 7. The first bolts 9 pass through the vertical plate 8 and are threadedly connected to the vertical plate 6. A pair of sliders 12 are fixed to the outer wall of the disc 7. The sliders 12 are slidably connected to the vertical plate 6 through the sliding groove 13. Elastic elements 14 are fixed to both sides of the sliders 12. The elastic elements 14 are fixedly connected to the vertical plate 6. Multiple pairs of guide wire groove wheels 19 are installed on the side of the vertical plate 6 away from the base plate 2. The outer wall of the guide wire groove wheels 19 is covered with chemical fiber threads 22.

[0026] In the specific implementation process, it is worth noting that the top plate 1 and the base plate 2, as the basic support components of the wire guide unit, are both made of high-strength alloy steel to ensure that they can withstand large forces without deformation during long-term use. Screws are inserted into the lower surface of the top plate 1, which can be used to install the whole structure in a suitable position. The cylinder 3 and the base plate 2 are rotatably connected by ball bearings. The spring 4 is made of high-quality spring steel with an elastic coefficient of 2-15 N / CM, which can provide stable and appropriate tension during the transmission of the chemical fiber 22. The shell 5 not only serves to fix the outer ring of the spring 4, but also protects the internal components such as the spring 4, preventing external impurities from entering and affecting its normal operation. The upright plate 8 can install the two pairs of upright plates 6 into a certain whole by the first bolt 9. The slider 12 can slide in an arc trajectory inside the slide groove 13. The elastic element 14 is a compression spring with an elastic coefficient of 2-10 N / CM.

[0027] Furthermore, protruding rods 11 are fixedly connected to the center of both the front and rear surfaces of the disc 7, and the protruding rods 11 are rotatably connected to the vertical plate 8 through the circular groove 10.

[0028] In the specific implementation process, it is worth noting that the surface of the protruding rod 11 is finely polished to ensure smoother rotational engagement with the circular groove 10 and reduce energy loss caused by friction. The inner wall of the circular groove 10 is specially lubricated to further reduce the resistance when the protruding rod 11 rotates. The upright plate 8 is made of sturdy metal material, which can improve the stability of the disc 7.

[0029] Furthermore, a pair of plates 15 are attached to the surface of the vertical plate 6 away from the substrate 2. The plates 15 are connected to the vertical plate 6 by a second bolt 16. A round rod 17 is fixedly connected to the center of the surface of the plates 15 away from the vertical plate 6. A round shaft 18 is rotatably connected to the outer wall of the round rod 17. The round shaft 18 has a multi-segment structure, and the multiple segments of the round shaft 18 are threaded together. The outer wall of the multiple segments of the round shaft 18 is clearance-fitted with the outer wall of the guide wire groove wheel 19. A collar 20 is fixedly sleeved on one end of the outer wall of the round shaft 18. A pair of third bolts 21 are inserted into the surface of the collar 20 away from the guide wire groove wheel 19. The third bolts 21 pass through the collar 20 and are threadedly connected to the guide wire groove wheel 19.

[0030] In the specific implementation process, it is worth noting that the round shaft 18 is rotatably connected to the round rod 17 through ball bearings. The multi-segment structure design of the round shaft 18 makes it more convenient and flexible to install and disassemble the guide wire groove wheel 19. The threaded connection between each segment of the round shaft 18 adopts a high-precision thread processing technology to ensure the firmness and stability of the connection.

[0031] Furthermore, a pair of circular blocks 23 are provided between adjacent guide wire groove wheels 19, and both ends of the circular blocks 23 are fixedly connected to the insert rods 24. The insert rods 24 are connected to the guide wire groove wheels 19 through slots 25.

[0032] In the specific implementation process, it is worth noting that the surface of the insertion rod 24 is barbed to increase the friction between it and the slot 25, ensuring a more secure connection. The size of the slot 25 is precisely designed to fit tightly with the insertion rod 24, preventing the insertion rod 24 from loosening or falling off during operation. This can improve the stability between the multiple horizontal guide rollers 19, and facilitate the synchronous rotation of the multiple horizontally arranged guide rollers 19 when guiding various chemical fiber threads 22.

[0033] Furthermore, a magnetic block 26 is fixedly connected inside the slot 25, and the magnetic block 26 is magnetically attracted to the insertion rod 24.

[0034] In the specific implementation process, it is worth noting that the magnetic block 26 is made of a strong magnetic material, and its magnetic force is precisely adjusted to ensure that it has sufficient attraction force on the insertion rod 24, but will not be difficult to disassemble due to excessive magnetic force. The corresponding position of the insertion rod 24 is made of a material that can generate good magnetic attraction with the magnetic block 26, ensuring that the connection between the two is stable and reliable. This magnetic attraction design makes the connection between adjacent guide wire groove wheels 19 tighter, and at the same time improves the overall stability of the device to a certain extent.

[0035] Furthermore, the end of the round shaft 18 furthest from the vertical plate 6 is threaded with a plug 27.

[0036] In the specific implementation process, it is worth noting that the material of the plug 27 is a metal material that matches the round shaft 18, and its thread specification is fully compatible with the thread at the end of the round shaft 18. The plug 27 can not only seal the end of the round shaft 18 to prevent dust and impurities from entering the thread groove of the round shaft 18, but also facilitate subsequent use.

[0037] Furthermore, the end of the insertion rod 24 away from the circular block 23 has a tapered structure.

[0038] In the specific implementation process, it is worth noting that the conical structure design makes it easier to align and insert the insertion rod 24 into the slot 25, reducing the difficulty and time in the installation process.

[0039] Working principle:

[0040] The principle of stable conduction in synthetic fiber threads:

[0041] The operator places the synthetic fiber 22 to be guided onto the outer wall of the guide wheel 19. When the synthetic fiber 22 is pulled and moved, the guide wheel 19 begins to guide it. During the guiding process, if the traction force on the synthetic fiber 22 is transverse, this transverse force will be transmitted to the vertical plate 6 in sequence through the guide wheel 19, the round shaft 18, the round rod 17 and the plate 15. The vertical plate 6 rotates at a certain angle around the disc 7, thereby causing the guide wheel 19 to swing in the direction of the offset force of the synthetic fiber 22. This swinging mechanism can increase the probability that the synthetic fiber 22 is at the center of the guide wheel 19 during the transmission, effectively reducing the probability that the synthetic fiber 22 will detach from the guide wheel 19, thus ensuring the stability of the synthetic fiber guiding operation.

[0042] Tension supply principle:

[0043] During the transmission process of the chemical fiber thread 22, the chemical fiber thread 22 will apply a certain force to the guide wheel 19. This force will cause the upper and lower guide wheels 19 to revolve around the cylinder 3. During this period, the cylinder 3 will rotate at a corresponding angle according to the intensity of the force applied by the chemical fiber thread 22 to the guide wheel 19. At the same time, the mainspring 4 will undergo a certain degree of compression deformation. The elastic potential energy generated by the compression deformation of the mainspring 4 will cause the guide wheel 19 to generate a force opposite to the force applied by the chemical fiber thread 22. This reverse force provides the necessary tension for the transmission of the chemical fiber thread 22, ensuring that the chemical fiber thread 22 can achieve high-quality transmission and avoiding the influence of insufficient or excessive tension on the guiding effect and fiber quality.

[0044] Principle of adjusting the number of guide rollers:

[0045] Because the round shaft 18 adopts a detachable segmented structure, and each segment of the round shaft 18 is equipped with a guide roller 19 on its outer side, and adjacent guide rollers 19 can be connected through the insertion rod 24 and slot 25 structure, operators can flexibly increase or decrease the number of guide rollers 19 according to actual production and processing needs. When it is necessary to process more strands of chemical fiber or adapt to different specifications of production requirements, the number of guide rollers 19 can be increased; when production needs are reduced or the equipment structure needs to be simplified, the number of guide rollers 19 can be reduced. This adjustable design allows the multi-groove guide for chemical fibers to meet different processing needs, effectively expanding its application range.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
