DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a mechanism for automatically replacing the excessively worn crimping wheel of a chemical fiber crimping machine. Figure 1-7 As shown, it includes a base plate 1, on which a workbench 2 is fixedly installed. The workbench 2 is provided with two upper and lower symmetrical holes 21, which penetrate the workbench 2. A curling wheel 4 is arranged in the hole 21. A slide groove 3 is fixedly installed on the back of the workbench 2, and the slide groove 3 is aligned with the hole 21. A vertical plate 11 is welded on the top of the base plate 1 and on the front of the workbench 2.

[0028] The vertical plate 11 is fixedly mounted with a curling knife 5, and the vertical plate 11 vertically penetrates the curling knife 5, and a bolt thread penetrates 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 fixedly installed outside the shaft of the vertical plate 11. The curling knife 5 is located between the light sensing module and the light emitter 10. The light emitter 10 emits red light, and the curling knife 5 blocks the light emitter 10. When the curling knife 5 is worn beyond a preset value, the curling knife 5 can no longer block the light emitter 10. At this time, the light emitted by the light emitter 10 can be captured by the light sensing module, and the information is fed back to the outside world, so as to notify the workers in time. The workers replace the curling knife 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. The magnetic ball 7 and the magnet column 25 generate a mutually attractive magnetic force. 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 at 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 outside the support rod 63. The moving block 8 is well matched 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 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 to make the moving block 8 exert force on 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 is excessively worn, the middle spring 64 expands to make the slide bar 62 move closer to the winding wheel 4. The support rod 63 moves with the slide bar 62, and the magnetic ball 7 and the magnet column 25 move away from each other. The magnetic ball 7 and the magnet column 25 move away from each other, causing the suction force to gradually weaken.

[0036] As the contact point between the support rod 63 and the moving block 8 changes, the lever arm close to 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, so that the force applied by the moving block 8 to the force measuring unit 9 changes. The force measuring unit 9 feeds back information to the outside world.

[0037] The front end of the curling wheel 4 extends to the front of the workbench 2, and the roller 6 contacts the front end surface of the curling wheel 4. There is a depression in the center of the curling 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 curling wheel 4, and the sliding ring 43 and the slider 41 are slidably matched. The sliding ring 43 is connected to the outside of the sliding ring 43 with a placement groove 44, and tooth grooves 42 are provided on the inner walls on both sides of the depression of the curling wheel 4.

[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 the upper and lower 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 to play a fixing role.

[0040] A chamber 22 is provided in the workbench 2, the chamber 22 is communicated with the hole 21, the chamber 22 corresponds to the tooth groove 42, an electric push rod 23 is fixedly installed in the chamber 22, 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 meshes with the tooth groove 42.

[0041] When replacing the winding wheel 4, the electric push rod 1 12 and the electric push rod 2 23 are retracted to pull the worn and unusable winding wheel 4 out of the hole 21, and the new winding wheel 4 is pushed from the slide groove 3 into the hole 21, and then the electric push rod 1 12 and the electric push rod 2 23 are extended, and the movable section of the electric push rod 1 12 is inserted into the placement groove 44 to fix the new winding wheel 4 in the hole 21. The electric push rod 23 is extended to push the gear 24 out of the chamber 22, so that the gear 24 is meshed with the tooth groove 42.

[0042] The rear end of the slide 3 is fixed with a back plate 31 by means of screws, and 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. The back plate 31 is clamped with a railing 33, and the railing 33 separates the winding wheel 4 in use from the unused winding wheel 4. When replacing the winding wheel 4, first drag the old one out of the hole 21, pull out 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 curling wheels of the chemical fiber crimping machine sets the curling wheel 4 to be detachable, sets a chute 3 on the back of the workbench 2, and delivers the new curling wheel 4 into the workbench 2 through the chute 3 and the large spring 31. The movable block 8, the force measuring unit 9, and the small spring 91 are set up to form a lever principle, and the distance between the magnet 7 and the magnet column 25 changes according to the degree of wear of the curling wheel 4. When the distance between the magnet 7 and the magnet column 25 changes, the value measured by the force measuring unit 9 changes, thereby achieving the purpose of automatically detecting the curling wheel 4 and timely notifying the worker that the curling wheel 4 is seriously worn.

[0044] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
