Description

Technical Field

[0001] The invention relates to the technical field of radiation modification, in particular to a radiation modification device and a modification method for acrylic yarn fibers. Background Art

[0002] Yarn irradiation is a technology that uses Y-rays, electron beams, plasma, microwaves, ultraviolet rays and other rays to stimulate and induce yarns to produce physical and chemical changes. This technology can improve the surface structure and performance of yarns and give textile materials new functions, such as enhancing human microcirculation, regulating blood flow, low-temperature far-infrared, and natural antibacterial properties.

[0003] At the same time, irradiation technology is also used for surface modification of yarn. The sizing effect of starch slurry after chemical modification is achieved through physical modification. It not only reduces the cost of slurry use, but also saves energy consumption in the process of sizing and desizing of grey cloth, and reduces the environmental pollution of desizing. In addition, irradiation technology is also considered to be a green and clean technology because its process produces almost no pollution. These advantages make yarn irradiation have broad application prospects in the textile industry. Therefore, the yarn needs to be modified by the irradiator in production, that is, the yarn is passed through the modification chamber of the irradiator to complete the modification operation.

[0004] A fiber surface laser irradiation device disclosed in a patent application with reference publication number CN210177256U uses laser to irradiate the fiber surface, which has low energy consumption and low cost. The laser light source beam splitting mechanism can irradiate from both the upper and lower directions of the fiber, further improving the irradiation uniformity.

[0005] The above-mentioned irradiation device can perform stable irradiation treatment on the yarn through the light beam adjustment mechanism and the second light beam adjustment mechanism, but the irradiation device cannot perform synchronous irradiation treatment on multiple groups of yarns at a time, which reduces the irradiation efficiency and increases the irradiation cost. In addition, the irradiation device does not have an active traction function. Therefore, when the yarn breaks or is replaced in the irradiation device, the irradiation device needs to be frequently disassembled and opened to rearrange the yarn, which affects the irradiation effect of the yarn, delays the progress of the irradiation work, and increases the maintenance workload.

[0051] Wherein, the clamping member includes a concave seat 16, the two ends of the concave seat 16 are respectively detachably fixedly connected with the two rotating shafts 15, two lifting areas 17 are symmetrically provided on both sides of the concave seat 16, and sliders 18 are slidably installed in the two lifting areas 17, and a pressing piece 19 is commonly installed between the two sliders 18, and a No. 1 power chamber 20 is installed at the bottom of each lifting area 17, and a No. 1 piston member 21 is slidably installed in the No. 1 power chamber 20, and the top of the No. 1 piston member 21 is detachably fixedly connected to the lower surface of the slider 18, and a No. 1 spring 22 is installed between the bottom of the No. 1 piston member 21 and the No. 1 power chamber 20, and a No. 1 annular baffle plate for blocking the No. 1 piston member 21 is provided at the top of the No. 1 power chamber 20, and the No. 1 spring 22 is used to pull the pressing piece 19 to move toward the concave seat 16, and an intercommunication pipe 23 is installed at the bottom of the No. 1 power chamber 20, and the intercommunication pipe 23 passes through the annular plate 25 and communicates with the annular cavity 24;

[0052] Among them, an annular cavity 24 is concentrically sleeved at both ends of the concave seat 16, and a certain amount of medium is introduced into the annular cavity 24. The medium is specifically one of gas and liquid. The medium can be freely switched and used according to the working environment to ensure the power coordination and linkage between the No. 1 power chamber 20 and the No. 2 power chamber 31. The annular cavity 24 is detachably fixedly connected to the vertical arm 14 through a bracket. The annular cavity 24 is openly designed toward the side of the concave seat 16. An annular plate 25 is rotatably sealed and installed on the annular cavity 24. The annular plate 25 is detachably fixedly connected to the concave seat 16 through a bracket, and a No. 1 air pipe 26 is connected and installed on one side of the bottom of the annular cavity 24. The pressing piece 19 includes a concave piece 191. The two ends of the concave piece 191 are detachably fixedly connected to the two sliders 18 respectively. On both sides of the concave piece 191 An adjustment area 192 is provided through each of the two adjustment areas 192, and an adjustment block 193 is slidably engaged in each of the two adjustment areas 192. A roller 194 is rotatably installed between the two adjustment blocks 193. When the electromagnet 27 is powered off, the roller 194 is located at the top and in contact with the yarn body 9, and the concave seat 16 is limited by the engagement of the rack 35 with the gear 36. An adjustment spring 195 is installed between the adjustment block 193 and the adjustment area 192. A pressing plate 196 is installed on the concave seat 16 toward the concave member 191. Two strip grooves 197 are symmetrically provided on the upper surface of the pressing plate 196, and two strip members 198 are symmetrically installed on the lower surface of the concave member 191. The two strip members 198 can extend into the strip groove 197 correspondingly, and the size of the strip member 198 is smaller than the size of the strip groove 197.

[0053] In the embodiment of the present invention, the trigger assembly includes an electromagnet 27 installed at the bottom of the sliding chamber 12. After the electromagnet 27 is energized, it can repel and push the permanent magnet plate 28, and a permanent magnet plate 28 is slidably installed in the sliding chamber 12. The permanent magnet plate 28 is correspondingly slidably engaged in the open area 13. A push spring 29 is installed at the top of the sliding chamber 12 through a bracket. The bottom of the push spring 29 is connected to the upper surface of the permanent magnet plate 28. The permanent magnet plate 28 is pushed toward the electromagnet 27 by the push spring 29, and push plates 30 are symmetrically installed at both ends of the permanent magnet plate 28. The push plates 30 are slidably engaged with the side walls of the sliding chamber 12, and a No. 2 power chamber is installed at the bottom of both sides of the sliding chamber 12. 31, the No. 2 power chamber 31 is detachably fixedly connected to the sliding chamber 12 through a bracket, and a No. 2 piston member 32 is slidably installed in each No. 2 power chamber 31, and the top of the No. 2 piston member 32 is detachably in contact with the push plate 30. The top of the No. 2 power chamber 31 is open, and a No. 2 annular baffle is provided on the top of the No. 2 power chamber 31 to block the No. 2 piston member 32, and a No. 2 spring 33 is installed between the bottom of the No. 2 piston member 32 and the No. 2 power chamber 31, and the No. 2 spring 33 is used to drive the push plate 30 to move away from the electromagnet 27, and a No. 2 air pipe 34 is installed on one side of the No. 2 power chamber 31, and the No. 2 air pipe 34 is connected to the No. 1 air pipe 26 through a pipeline;

[0054] It is worth noting that: when simulating the traction of the yarn body 9: by providing a guiding mechanism, when the line is broken or changed during the irradiation process, the technician only needs to pass the front end of the yarn body 9 through the pressure piece 19 and the concave seat 16, and then energize the electromagnet 27, and control the current of the electromagnet 27 to gradually increase. The energized electromagnet 27 completes the repulsive push on the permanent magnet plate 28, pushing the permanent magnet plate 28 to slide upward in the sliding chamber 12. Under this path, the push plate 30 follows the permanent magnet plate 28 to move upward. At this time, the No. 2 spring 33 is elastically reset to push the No. 2 piston member 32 upward. Part of the medium in the annular cavity 24 is sucked into the No. 2 power chamber 31. Since the annular cavity 24 is interconnected with the No. 1 power chamber 20 and the No. 2 power chamber 31, the No. 1 spring 22 in the No. 1 power chamber 20 moves down and resets, pulling the pressure piece 19 to follow the slider 18 to move down in the lifting area 17. During the downward movement, the pressure piece 19 comes into contact with the concave seat 16 to complete the pressing action on the yarn body 9. At the same time, with the cooperation of the strip groove 197 and the strip piece 198, the pressing effect on the yarn body 9 is improved to prevent it from falling off. After the pressure piece 19 moves down to press the yarn body 9, the push plate 30 continues to move upward. Since the rack 35 is meshed with the gear 36, the push plate 30 moves upward, and the rotating shaft 15, the concave seat 16, and the pressing piece 19 are pushed to rotate synchronously, and the yarn body 9 is wound around the concave seat 16 and the pressing piece 19, ensuring the stability of the yarn body 9 during the traction process. Then the electric slide 10 is started to pull the yarn body 9 toward the other end of the modified space 4 to complete the traction work. The overall operation is convenient. The technician only needs to freely control the corresponding guiding mechanism according to the needs of the yarn body 9, which saves time and effort. The traction work can be completed without turning on the irradiator 1. To avoid interfering with other yarn bodies 9, after the traction is completed, the current of the control electromagnet 27 is gradually reduced, and the permanent magnet plate 28 is moved down and reset under the reset of the push spring 29, and the rack 35 and the gear 36 are gradually reset, so that the wound yarn body 9 is automatically released, and finally the push plate 30 moves down to push the No. 2 piston member 32 to reset to the bottom of the No. 2 power chamber 31 and compress the No. 2 spring 33, and synchronously drives the No. 1 piston member 21 to move in the No. 1 power chamber 20 to raise and reset the pressure member 19, so that the technicians can pull out the yarn body 9 for subsequent traction work;

[0055] Among them, racks 35 are symmetrically installed on the upper surfaces of the two push plates 30, and gears 36 meshing with the racks 35 are fixedly sleeved on the outside of the two rotating shafts 15. When the push plate 30 is reset to the bottom, the racks 35 mesh with the gears 36. When the push plate 30 moves up to the top, the racks 35 mesh with the gears 36.

[0056] Embodiment 4: A method for irradiation modification of acrylic yarn fiber, comprising the following steps:

[0057] Step 1: First, assemble two connecting frames 7 correspondingly on the semicircular tubes 6 at both ends of one of the half chambers 3;

[0058] Step 2, then passing the multiple groups of yarn bodies 9 through the conveying stations 8 on the two connecting frames 7 respectively, so that the multiple groups of yarn bodies 9 pass through the modified space 4 together;

[0059] Step 3, completing tension control of the yarn body 9 in the modified space 4 through the positioning component;

[0060] Step 4: The trigger component synchronously drives the positioning component to complete the rotation, and the yarn body 9 is wound on the positioning component, instead of manually pulling the yarn body 9 to move to the other end of the modification space 4, and then the technicians perform subsequent threading of the yarn body 9.

[0061] The present invention provides an irradiation modification device and modification method for acrylic yarn fibers, and the specific working principle is as follows: first, two connecting frames 7 are correspondingly assembled on the semicircular tubes 6 at the two ends of one of the half cavities 3, and then multiple groups of yarn bodies 9 are correspondingly passed through the conveying stations 8 on the two connecting frames 7, so that the multiple groups of yarn bodies 9 pass through the modification space 4 together, and multiple irradiation units 5 are arranged in the modification space 4, so that the modification space 4 is evenly filled with light beams, thereby improving the modification accuracy of the yarn bodies 9;

[0062] By arranging a plurality of guiding mechanisms on the crossbeam 11 of the electric slide 10, the yarn body 9 passes through the conveying station 8 and is set on the guiding mechanism. The positioning component can complete the tension control of the yarn body 9 in the modification space 4, so that the yarn body 9 maintains a stable state and moves in the modification space 4. When the line is broken or changed during the irradiation process, the trigger component is started to push the positioning component to move and clamp the yarn body 9. At the same time, under the push of the trigger component, the positioning component is synchronously driven to complete the rotation, and the yarn body 9 is wound around the positioning component, which further improves the limiting effect of the yarn body 9. Then the electric slide 10 is started to replace the manual traction of the yarn body 9 to the other end of the modification space 4. Then the technician can perform subsequent threading of the yarn body 9, which reduces the maintenance difficulty of the technician. There is no need to repeatedly open and thread the irradiator 1, which avoids affecting other yarn bodies 9 and will not interfere with the irradiation progress, so that the irradiation modification work can be carried out uninterruptedly, thereby improving the irradiation modification efficiency.
