Description

Technical Field

[0001] The utility model relates to the field of clothing making, in particular to an automatic elastic buckle cord threading device. Background Art

[0002] Elastic buckles are a common elastic structure, often used on hats or cuffs on clothes. During the production process, the elastic cord needs to be passed through the elastic buckle. When the pressure block of the elastic buckle is not pressed, the spring will push up the pressure block and the elastic cord cannot be freely extended or retracted. When the pressure block is squeezed, the elastic cord can freely pass through the through hole in the middle to expand or contract. During the clothing production process, it is often necessary to pass the elastic cord through the thread hole of the elastic buckle.

[0003] The current automatic elastic buckle rope threading device, as described in the patent with announcement number CN209807209U, includes a base plate installed on a workbench; a positioning mold, having a positioning slot and a plurality of waist-shaped mounting holes, the positioning slot is used to place the elastic buckle, and the waist-shaped mounting holes are used to fix the positioning mold on the base plate; a first cylinder, located on one side of the positioning mold and fixedly mounted on the base plate, wherein the moving direction of the cylinder rod of the first cylinder is consistent with the axial direction of the rope threading hole of the elastic buckle; a guide rod, installed on the cylinder rod of the first cylinder, and the front end of the guide rod has a traction portion.

[0004] With regard to the above-mentioned related technologies, the inventor believes that although the setting of the protrusion can prevent the elastic rope from falling off automatically, when the elastic rope needs to be removed from the traction part after the rope is threaded, if the traction rope is thicker, the elastic rope will be difficult to automatically detach from the traction part due to the limitation of the protrusion. Therefore, workers are required to manually remove the elastic rope from the traction, thereby increasing the labor intensity. Utility Model Content

Guide rods 204 are slidably penetrated through the four corners of the inner side of the fixed seat 201, and each group of guide rods 204 is fixedly connected to the base 101. The setting of the guide rods 204 can guide the up and down movement of the fixed seat 201.

[0028] The interior of the fixed seat 201 is fixedly connected with a second cylinder 202, and the output end of the second cylinder 202 is fixedly connected with a traction hook 203. The second cylinder 202 is set to pull the traction hook 203 to move during the start-up work, so that after the traction hook 203 passes through the wire hole of the elastic buckle, the elastic rope can be hooked inside the traction hook 203. An integrated protrusion 206 is provided on the inner side of the traction hook 203. The setting of the protrusion 206 can start the limit function of the elastic rope after hooking, so as to reduce the probability of the elastic rope escaping from the traction hook 203. The rope-releasing mechanism 3 includes a third cylinder 302 symmetrically fixedly connected to the top of the base 101, and the output ends of the two groups of third cylinders 302 are fixedly connected with a top plate 301.

The first cylinder 107 is then started to extend the first cylinder 107, thereby squeezing the elastic buckle, so that the male buckle of the elastic buckle is aligned with the wire hole of the female buckle, and then the second cylinder 202 is started, so that the second cylinder 202 drives the traction hook 203 to penetrate the wire hole of the elastic buckle, and then the elastic rope to be worn is hooked inside the traction hook 203, and then the second cylinder 202 is started again, so that the second cylinder 202 drives the traction hook 203 to separate from the wire hole of the elastic buckle, thereby driving the elastic rope to penetrate the wire hole of the elastic buckle;

[0033] When the avoidance groove 207 on the towing hook 203 moves to a position relative to the second support rod 306 and the first support rod 305, the third cylinder 302 can be started, so that the third cylinder 302 drives the top plate 301, the second support rod 306 and the first support rod 305 to move downward, so that the second support rod 306 and the first support rod 305 pass through the avoidance groove 207, and then the second cylinder 202 is started, so that the second cylinder 202 drives the towing hook 203 to break away from the outside of the second support rod 306 and the first support rod 305, and then the fourth cylinder 313 is started. The fourth cylinder 313 drives the push plate 307 and the two sets of racks 309 to move, so that the racks 309 on both sides respectively drive the two sets of gears 308 to rotate in opposite directions, thereby driving the second support rod 306 and the first support rod 305 to rotate in opposite directions, thereby expanding the elastic rope, so that the second support rod 306 and the first support rod 305 press and fix the two sides of the elastic rope to the inside of the baffles 311 on both sides, and then continue to start the second cylinder 202, so that the second cylinder 202 drives The movable traction hook 203 moves to one side of the roller 102 until the elastic rope is separated from the traction hook 203 through the protrusion 206, and then the fourth cylinder 313 is started to contract, thereby driving the second support rod 306 and the first support rod 305 to rotate and reset, thereby stopping the compression of the elastic rope, and then the first cylinder 107 is started to stop the first cylinder 107 from squeezing the elastic buckle, and then the elastic buckle with a thick rope can be taken out from the inside of the positioning slot 105.
