Description

Technical Field

[0001] This invention belongs to the field of zipper machines and relates to a top-stop angled zipper threading machine. Technical Background

[0002] A zipper threading machine is a device used to automatically produce complete zippers by inserting the zipper pull into the zipper belt. The equipment first transports the zipper pull to the upper zipper pull mold, and then conveys it into the zipper belt channel through the upper zipper pull mold. Through a series of actions, the zipper pull is threaded onto the zipper belt.

[0003] Traditional zipper manufacturing involves first molding the bottom stop of the zipper belt, then using a zipper threading machine to install the top screw, and finally molding the top stop. This requires two injection molding processes. The new beveled top screw process, however, can mold both the bottom and top stops in one step, then create a bevel on the top stop to complete the top screw operation. This reduces the number of steps and the length of the production line.

[0004] Traditional chain threading machines insert the zipper head into the chain through the cutting edge, which is not suitable for chains with pre-molded top stops. For these types of chains, manual threading is currently the only option. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a top-stop angled chain threading machine. This device has the advantage of being able to thread the chain head onto a pre-molded top-stop chain, thereby achieving automated production and improving production efficiency.

The chain channel is provided with a bottom stop insertion block sensing mechanism. A top stop positioning mechanism is provided behind the bottom stop sensing mechanism. A pull head conveying mechanism is provided on the side of the top stop positioning mechanism. A top stop side push mechanism is provided behind the top stop positioning mechanism.

[0008] The upper stop positioning mechanism includes an upper stop positioning clamp, a moving drive device that drives the positioning clamp to move, and a clamping drive device that drives the positioning clamp to perform opening and closing actions. The positioning clamp includes two sub-clamps, the front end of which is a clamping part. The two clamping parts are provided with chain conveyor grooves at intervals. The height of the chain conveyor grooves is greater than the height of the chain conveyor belt but less than the upper stop height.

[0009] The pull head conveying mechanism includes a pull head base, an upper pull head mold set on the pull head base, an up-and-down drive device that drives the pull head base to move up and down, and a rotary drive mechanism that drives the pull head mold to rotate.

[0010] The upper stop side push mechanism includes a push block and a push block drive device that drives the push block to move left and right.

[0011] The present invention is further configured such that: the moving drive device includes a first cylinder that drives the positioning clamp to move back and forth, and a second cylinder that drives the positioning clamp to move left and right.

[0015] The present invention is further configured such that: the rotary drive mechanism further includes a rotary cylinder fixed on the pull head base, the output end of the rotary cylinder is rotatably connected to a rotating rod, a bearing is fixed on the pull head base, a rotating shaft is rotatably connected to the center of the bearing, the other end of the rotating rod is fixedly connected to the rotating shaft, the output end of the rotary cylinder extends out to drive the rotating shaft to rotate; the upper end of the rotating shaft is fixedly connected to the pull head mold.

[0016] The present invention is further configured such that: the upper pull head mold includes a mold base, a mold cavity matching the pull head is formed on the mold base, a lower stop block groove is provided at the rear end of the mold cavity, and a vertical groove for placing the pull ring is provided below the mold cavity.

[0017] The invention is further configured such that: a pull ring safety opening device is provided on one side of the vertical groove, including a pull hook, a linkage block and a safety cylinder. The pull ring end of the pull hook passes through the mold base and extends into the vertical groove. The linkage block is fixedly connected to the pull hook, the lower end of the linkage block is rotatably connected to the mold base, and the upper end of the linkage block is rotatably connected to the extended end of the safety cylinder.

[0020] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: This invention uses a lower stop block sensing mechanism to position the chain, and then a moving drive device for the upper stop positioning clamp moves the clamp to a fixed position. Because the upper stop positioning clamp has a chain groove, and the height of the groove is greater than the chain height but less than the upper stop height, when the upper stop positioning clamp moves, its side abuts against the front end of the upper stop, pulling the upper stop backward to the set position, thus positioning the upper stop and indirectly positioning the angled opening of the upper stop. Then, the upper pull head mold rises, and the positioning clamp positions the angled opening of the upper stop to the pull head side of the pull head mold. A rotation drive mechanism then rotates the pull head mold by a certain angle, aligning the pull head inlet with the angled opening. Next, a push block drive device pushes the angled opening of the upper stop into the pull head. Finally, a traction mechanism controls the chain to move forward, completing automated chain threading, thereby achieving automated production and improving production efficiency.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] A chain threading machine with an upper stop angled opening includes a chain traction mechanism 1 and a chain guide platform 101.

The lower stop insertion block sensing mechanism 2 includes a sensing switch 203, a connecting rod 202 and a sensing wheel 201. The connecting rod 202 is rotatably connected to the machine frame. The lower end of the connecting rod 202 is fixed with a rotating shaft 204. The sensing wheel 204 is rotatably sleeved on the rotating shaft 204. The upper end of the connecting rod 202 corresponds to the sensing switch 203.

[0045] The upper stop positioning mechanism 3 includes an upper stop positioning clamp 301, a moving drive device that drives the positioning clamp 301 to move, and a clamping drive device that drives the positioning clamp 301 to perform opening and closing actions. The positioning clamp 301 includes two sub-clamps 302. The front end of the sub-clamps 302 is a clamping part 303. The two clamping parts 303 are provided with chain belt through grooves 304 at intervals. The height of the chain belt through grooves 304 is greater than the height of the chain belt fabric and less than the height of the upper stop 901. In this way, the chain belt fabric 904 can move in the chain belt through grooves 304, and can only abut against the front end face of the upper stop 901 when it moves backward, so as to position the upper stop 901 to a set position.

[0046] The moving drive device includes a first cylinder 311 that drives the positioning clamp to move back and forth, and a second cylinder 321 that drives the positioning clamp to move left and right. The first cylinder 311 is fixed on the frame. The extended end of the first cylinder 305 is fixed with a first slide block 312. The bracket is provided with a first slide rail 313 corresponding to the first slide block 312. The second cylinder 321 is fixed on the first slide block 313. The extended end of the second cylinder 321 is fixedly connected to the second slide block 322. The clamping drive device includes a clamping cylinder 331 and a positioning clamp fixing member 332 fixed on the second slide block 322. The two positioning clamp fixing members 332 are respectively fixedly connected to two separate clamps 302. The tail end of the positioning clamp fixing member 332 is rotatably connected to the clamping cylinder 331. The tail ends of the two positioning clamp fixing members 332 extend into hinge ends 333 facing each other. The output end 334 of the clamping cylinder is hinged to the two hinge ends 333.

[0047] The pull head conveying mechanism 4 includes a pull head base 401 and an upper pull head mold 402 disposed on the pull head base 401; the rotary drive mechanism also includes a rotary cylinder 403 fixed on the pull head base 401, a rotating rod 404 rotatably connected to the output end of the rotary cylinder 403, a bearing 405 fixed on the pull head base 401, a rotating shaft 406 rotatably connected to the center of the bearing 405, the other end of the rotating rod 404 being fixedly connected to the rotating shaft 406, the upper end of the rotating shaft 406 being fixedly connected to the upper pull head mold 402, and the output end of the rotary cylinder 403 extending out to drive the rotating shaft 406 to rotate and drive the upper pull head mold to rotate;

[0048] The upper pull head mold 402 includes a mold base 411, on which a mold cavity 412 matching the pull head 8 is formed. The rear end of the mold cavity 412 is provided with a lower stop block groove 413, and the lower part of the mold cavity 412 is provided with a vertical groove 414 for placing the pull ring 81. A pull ring safety opening device is provided on one side of the vertical groove 414, including a pull hook 421, a linkage block 422 and a safety cylinder 423. The pull ring end 424 of the pull hook 421 passes through the mold base 411 and extends into the vertical groove 414 and into the buckle groove 82 of the pull ring 81. The linkage block 422 is fixedly connected to the pull hook 421. The lower end of the linkage block 422 is rotatably connected to the mold base 411, and the upper end of the linkage block 422 is rotatably connected to the extended end of the safety cylinder 423. The extension and retraction of the extended end of the safety cylinder 423 drives the linkage block 422 to rotate. The rotation of the linkage block 422 drives the pull hook 421 to pull down the pull ring 81 to open the safety.

[0049] The up and down driving device includes an up and down driving cylinder 431. The output end of the up and down driving cylinder 431 is connected to the pull head base 401. Guide posts 432 are provided on both sides of the pull head base 401. Guide grooves 433 corresponding to the guide posts 432 are provided on the frame.

[0050] The upper stop side push mechanism 5 includes a push block 501 and a push block drive device that drives the push block to move left and right. The push block 501 is set on the side of the mold cavity 412 of the pull head mold. When the pull head mold 402 rotates, the push block 501 pushes the upper stop inclined opening 902 into the pull head inlet 83 (due to the setting of the chain belt through groove 304, the chain belt cloth 904 can move in the chain belt through groove 304, so when the push block 501 pushes the upper stop, the positioning clamp will not clamp the cloth 904 and cause obstruction). The push block drive device includes a push block cylinder 502, which is fixed under the first slide 313. The extended end of the push block cylinder 502 is fixedly connected to the push block slide 503. The first slide 313 is also provided with a guide rail 504 corresponding to the push block slide 503. The push block 501 is fixed to the front end of the push block slide 503.

[0051] Working principle:

[0052] This patent application applies to a chain belt 9 that has both a top stop 901 and a bottom stop formed simultaneously. The chain threading action is achieved by forming a bevel 902 on the top stop 901 for the puller to pass through. The chain belt includes two sub-chain belts, one of which has a bottom stop formed with a bottom stop insert 903 and a top stop formed with a bevel 902; the other sub-chain belt has a bottom stop pin 906 and a standard top stop 901.

[0053] When the chain 9 enters the device, it is in a split chain state, each following an independent chain channel 102. The chain channel 102 of the split chain with the bevel 902 and the lower stop block 903 is equipped with a sensing wheel 201. When the chain moves forward, when the lower stop block 903 of the chain reaches under the sensing wheel 201, the sensing wheel 201 rotates through the connecting rod 202. The sensing switch 203 detects the rotation of the connecting rod 202, thereby controlling the chain traction mechanism 1 to stop traction, and the chain stops moving.

[0054] Next, the second cylinder 321 controls the positioning clamp 301 to extend towards the chain belt, and then the clamping cylinder 331 controls the positioning clamp 301 to retract. At this time, the positioning clamp 301 is in the transition section 907 between the two chain belt sections, that is, between the lower stop block 903 of the first chain belt section and the upper stop block 901 of the second chain belt section. The transition section 907 does not have chain teeth 905, only cloth belt 904. The transition section 907 is set in the chain belt through groove 304 of the positioning clamp 301. The first cylinder 311 controls the positioning clamp 301 to retract. When retracting, the side of the positioning clamp 301 abuts against the front end of the upper stop block 901 and retracts with the upper stop block 901 (the chain belt will also retract). Finally, it is positioned in the set position, that is, the side of the mold cavity 412 of the pull head mold (that is, the side of the pull head 8), so that the inclined opening 902 of the upper stop block is aligned with the inlet 83 of the pull head 8.

[0055] Then, the up-and-down drive cylinder 431 drives the upper pull head mold 402 to rise to the set position. Next, the rotation cylinder 403 controls the pull head base 401 to rotate 20-30°, so that the pull head inlet 83 is parallel to the inclined opening 902. The safety cylinder 423 controls the pull hook 421 to pull down the pull ring 81 to open the safety.

[0056] Then, the pusher cylinder 502 drives the pusher block 501 to move and push the upper stop oblique opening 902 into the inlet 83 of the pull head. Then, the clamping cylinder 331 controls the positioning clamp 301 to open, and the second cylinder 321 and the first cylinder 311 control the positioning clamp 301 to reset. Then, the chain traction mechanism 1 starts and drives the chain to move forward. The pull head 8 enters the chain through the oblique opening 902 to complete the chain threading.

[0057] Finally, push block 501 resets, upper pull head mold 402 rotates and resets, and descends to the initial position to prepare to receive the next pull head 8.

[0058] This invention has the feature of being able to complete the chain threading of the pull head using a pre-molded chain belt, thereby achieving automated production and improving production efficiency.

[0059] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
