Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber crimping machines, and in particular to an automatic replacement mechanism for a crimping wheel of a chemical fiber crimping machine that is excessively worn. Background Art

[0002] The crimping machine is a crucial forming tool in the polyester staple fiber production process. It primarily consists of two crimping wheels and two crimping blades. The crimping wheels are positioned vertically, with the crimping blades also positioned vertically between them. The combined force of the crimping wheels pushing the yarn bundle and the pressure between the crimping blades creates a resistance to the yarn bundle. These two forces gradually destabilize the yarn bundle, causing it to bend and deform, thus forming a crimped structure.

[0003] In the existing technology, the distance between the two crimping blades cannot be adjusted. The crimping machine operates at high speeds, and prolonged operation inevitably causes wear on the crimping wheel and crimping blades, resulting in errors in the process width on these blades. The crimping wheel and crimping blades are fixed in position and lack a sensor, preventing workers from being notified when the crimping wheel needs to be replaced. This, in turn, easily results in substandard products during the production process, wasting raw materials. Summary of the Invention

DETAILED DESCRIPTION

[0027] The embodiment of the application provides an automatic replacement mechanism of the excessive wear of the crimping wheel of a chemical fiber crimping machine. Figure 1-7 As shown in the figure, the automatic replacement mechanism of the excessive wear of the crimping wheel of the chemical fiber crimping machine comprises a bottom plate 1, the bottom plate 1 is fixedly installed with a workbench 2, the workbench 2 is provided with two holes 21 which are symmetrical above and below, the holes 21 penetrate through the workbench 2, the holes 21 are arranged with crimping wheels 4, the back of the workbench 2 is fixedly installed with a sliding groove 3, the sliding groove 3 is aligned with the holes 21, and the top of the bottom plate 1 and the front of the workbench 2 are welded with a vertical plate 11.

[0028] The vertical plate 11 is fixed with a curling knife 5, and the vertical plate 11 vertically passes through the curling knife 5, and a bolt thread passes through the vertical plate 11 and the curling knife 5. A replaceable curling wheel 4 is placed in the chute 3, and the vertical plate 11 is located on the right side of the curling wheel 4. The front of the workbench 2 is fixedly inlaid with a light emitter 10.

[0029] A light-sensing module is also fixed to the outside of the riser 11. The curling blade 5 is located between the light-sensing module and the light emitter 10. The light emitter 10 emits red light, which the curling blade 5 blocks. When the curling blade 5 wears beyond a preset value, the light emitter 10 is no longer blocked by the curling blade 5. The light emitted by the light emitter 10 is then captured by the light-sensing module and fed back to the outside world, promptly notifying the worker. The worker then replaces the curling blade 5.

[0030] It also includes a wear detection module. A magnet column 25 is fixedly installed on the front of the workbench 2 and on the right side of the vertical plate 11. The front end of the wear detection module is in conflict with the curling wheel 4. The end of the wear detection module is connected to a magnetic ball 7. A magnetic force of mutual attraction is generated between the magnetic ball 7 and the magnet column 25. A groove 111 is opened in the vertical plate 11. A force measuring unit 9 is fixedly installed in the groove 111. The distance between the magnetic ball 7 and the magnet column 25 is different, so that the wear detection module applies different degrees of force to the force measuring unit 9.

[0031] The wear detection module includes a roller 6, a bracket 61, a slide rod 62, a support rod 63, and a middle spring 64. The roller 6 is pivoted to the bottom of the bracket 61. The roller 6 is in conflict with the curling wheel 4. The front end of the slide rod 62 is welded to the bracket 61. The end of the slide rod 62 extends into the groove 111 and is fixedly installed with the support rod 63. The support rod 63 has a certain toughness, and the end of the support rod 63 is fixedly installed with the magnetic ball 7.

[0032] It also includes a moving block 8, which is sleeved on the outside of the support rod 63. The moving block 8 cooperates well with the inner wall of the groove 111. The moving block 8 can move up and down. A small spring 91 is fixedly installed between the force measuring unit 9 and the moving block 8.

[0033] The middle spring 64 is in a compressed state, one end of the middle spring 64 abuts against the bracket 61 , and the other end of the middle spring 64 abuts against the vertical plate 11 .

[0034] Combined with attachment Figure 2 、 6 In normal working state, the magnetic ball 7 and the magnet column 25 attract each other, and the support rod 63 forms a lever with the moving block 8, the small spring 91 and the force measuring unit 9. The entire support rod 63 bends so that the moving block 8 applies force to the force measuring unit 9.

[0035] Working Principle: Due to the middle spring 64, the roller 6 always contacts the winding wheel 4. When the winding wheel 4 becomes excessively worn, the middle spring 64 expands, causing the slide bar 62 to move closer to the winding wheel 4. The support rod 63 follows the movement of the slide bar 62, causing the magnetic ball 7 to move away from the magnet column 25. As the magnetic ball 7 and the magnet column 25 move away from each other, the suction force gradually weakens.

[0036] Because the contact point between the support rod 63 and the moving block 8 changes, the lever arm near the magnetic ball 7 becomes shorter, and the entire support rod 63 tends to be straight due to its own toughness. At this time, the moving block 8 moves with the support rod 63, causing the force applied by the moving block 8 to the force measuring unit 9 to change. The force measuring unit 9 feeds back this information to the outside world.

[0037] The front end of the winding wheel 4 extends to the front of the workbench 2, and the roller 6 contacts the front end surface of the winding wheel 4. There is a depression in the center of the winding wheel 4, and sliders 41 are arranged at equal angles in the depression. A sliding ring 43 is sleeved on the central depression of the winding wheel 4, and the sliding ring 43 slides with the slider 41. The outside of the sliding ring 43 is connected to a placement groove 44, and the inner walls on both sides of the depression of the winding wheel 4 are provided with tooth grooves 42.

[0038] The ring 43 of the crimping wheel 4 is used to abut against the inner wall of the hole 21 .

[0039] The bottom plate 1 is fixedly mounted with electric push rods 12 on both sides. The two electric push rods 12 correspond to the two holes 21 one by one. The movable ends of the electric push rods 12 extend vertically into the holes 21 and are fixedly plugged into the placement grooves 44. This plays a fixing role.

[0040] A chamber 22 is provided in the workbench 2, which is communicated with the hole 21 and corresponds to the tooth groove 42. An electric push rod 23 is fixedly installed in the chamber 22, and a motor is fixedly installed at the movable end of the electric push rod 23. A gear 24 is welded to the motor drive shaft. One side of the gear 24 extends from the chamber 22 and engages with the tooth groove 42.

[0041] When replacing the winding wheel 4, the electric push rod 12 and the electric push rod 23 are retracted to remove the worn and unusable winding wheel 4 from the hole 21, and the new winding wheel 4 is pushed from the slide groove 3 into the hole 21. Then the electric push rod 12 and the electric push rod 23 are extended, and the movable section of the electric push rod 12 is inserted into the placement groove 44 to fix the new winding wheel 4 in the hole 21. The extension of the electric push rod 23 pushes the gear 24 out of the chamber 22, so that the gear 24 engages with the tooth groove 42.

[0042] A back plate 31 is screwed to the rear end of the chute 3. A large spring 32 is welded to the back plate 31. The large spring 32 extends into the back plate 31 and contacts the replacement winding wheel 4. A railing 33 is attached to the back plate 31, separating the used winding wheel 4 from the unused one. To replace the winding wheel 4, first pull the old one out of the hole 21, remove the railing 33, and the large spring 31 pushes the new winding wheel 4 into the hole 21.

[0043] In summary, the automatic replacement mechanism for excessively worn crimping wheels in this chemical fiber crimping machine utilizes a detachable crimping wheel 4. A chute 3 is provided on the back of a workbench 2, which cooperates with a large spring 31 to deliver a new crimping wheel 4 into the workbench 2. A movable block 8, a force-measuring unit 9, and a small spring 91 cooperate to form a lever mechanism. The distance between magnet 7 and magnet column 25 changes according to the degree of wear of the crimping wheel 4. As the distance between magnet 7 and magnet column 25 changes, the value measured by the force-measuring unit 9 changes, thereby automatically detecting the crimping wheel 4 and promptly notifying workers of severe wear of the crimping wheel 4.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
