DETAILED DESCRIPTION

[0034] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, left, right, front, back, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0036] In the description of this utility model, if there is a description of a wire sleeve or a bracket, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] The chain link is a component of the chain, usually supported by metal or polymer wear-resistant materials. It transmits power and motion by meshing with the sprocket and sprocket teeth, and is an indispensable part of the chain transmission system. During the chain production process, the chain link units often need to be connected in series after they are manufactured to facilitate storage or transportation processing. In related technologies, the process of connecting the chain link units to the bobbin is often completed manually, which has obvious problems of low efficiency and high labor costs. In addition, manual chaining operations are prone to errors, making it difficult to ensure accurate positioning and stable connection between the chain link units and the bobbin, resulting in low yield rates.

[0039] To improve the automation and production efficiency of chain unit concatenation, a number of automatic chain unit concatenation devices have emerged on the market. However, these devices often have complex structures and high maintenance costs, and they still have many deficiencies in key aspects such as chain supply, spool positioning, and chain push and connect. For example, the chain supply often lacks an effective screening mechanism, resulting in problems such as blockage and misalignment of the chain units during transportation. The spool positioning accuracy is low, and the push assembly design is unreasonable, making it impossible to accurately clamp and stably push the chain units, affecting concatenation efficiency and yield rate.

On the upper and lower sides of the pushing block 420, the middle part of each clamping arm 450 is rotatably connected to the pushing block 420, and one end of each clamping arm 450 is provided with a clamping claw 451 located on the side of the pushing block 420 close to the positioning plate 330, and the two clamping claws 451 are respectively located on the upper and lower sides of the hole 421 through which the positioning is made, and the other end of each clamping arm 450 is provided with a clamping slide 452, and the fixed block 430 is provided with two clamping grooves 431 respectively matching the two clamping slides 452, and the two clamping grooves 431 are respectively located on the upper and lower sides of the pushing block 420, and the clamping slide 452 is provided. 52 is slidably connected to the clamping slot 431, and the clamping slot 431 is extended along the extension direction of the spool. The clamping slot 431 is inclined close to the pushing block 420 along the forward direction of the pushing block 420. The clamping slot 431 is used to guide the clamping slide 452 to move close to the pushing block 420 when the pushing block 420 moves forward so that the clamping claw 451 releases the chain unit. The clamping slot 431 is also used to guide the clamping slide 452 to move away from the pushing block 420 when the pushing block 420 retreats so that the clamping claw 451 cooperates with the pushing block 420 to clamp the chain unit.

[0045] In operation, in the initial state, the clamping slide rod 452 is located at the end of the clamping slide groove 431 away from the positioning block, at this time the clamping slide rod 452 is located at the position away from the push block 420 in its movement track, the clamping jaw 451 is located at the position close to the push block 420 in its movement track, at this time the two clamping jaws 451 and the push block 420 close to the side of the positioning plate 330 form a positioning groove 331 for accommodating the positioning chain piece unit; the screening drive mechanism 220 drives the screening disc 210 to move to screen out the chain piece unit therein and output to the screening outlet 211, these material piece units are conveyed to the positioning groove 331 between the two clamping jaws 451 and the push block 420 through the guide slide rail 414 under the action of gravity; the spool is placed into the positioning groove 331 of the positioning plate 330 by manual or mechanical method, the push drive mechanism 410 drives the push block 420 to advance close to the positioning plate 330, the clamping slide rod 452 advances with the push block 420, the clamping slide rod 452 advances along the clamping slide groove 431 close to the positioning plate 330, the chain piece unit is strung into the spool under the pushing action of the push block 420, in the process of continuous advancement of the push block 420, the clamping slide rod 452 continuously moves close to the push block 420, since the middle part of the clamping arm 450 is rotationally connected with the push block 420, the clamping jaw 451 rotates away from the push block 420 around the middle part of the clamping arm 450, so as to release the chain piece unit, at this time the chain piece unit is strung into the deeper position of the spool, and one end of the spool is inserted into the through positioning hole 421; the push drive mechanism 410 drives the push block 420 to retreat away from the positioning plate 330, so that the push block 420 is separated from the chain piece unit which has completed the stringing, the clamping slide rod 452 retreats with the push block 420 and resets under the guidance of the clamping slide groove 431, preparing for the next stringing process.

[0046] Through the special structure of the pushing component 400 in conjunction with the chain supply component 200 and the spool positioning component 300, the chain unit can be inserted into the spool to realize continuous stringing processing, with high processing efficiency, no need for direct manual operation, which can effectively save labor costs and achieve good stringing effect. Through the screening plate 210 in conjunction with the screening drive mechanism 220, orderly and accurate chain unit supply can be achieved, which can significantly reduce the occurrence of problems such as blockage and misalignment; in addition, the pushing drive mechanism 410, the pushing block 420, the fixing block 430, the guide rail 440 and the two clamping arms 450 work together to achieve precise clamping and stable pushing of the chain unit, and the sliding connection and tilting design of the clamping slide bar 452 and the clamping slide groove 431 realize the clamping claw 451 The automatic loosening and clamping when the pushing block 420 moves forward and backward greatly improves the stringing efficiency. Before the pushing block 420 moves forward to the end point, the two clamping claws 451 on one side of the pushing block 420 can ensure the stable clamping of the chain unit during the pushing process, avoiding slipping and dislocation, and can effectively improve the accuracy of the string alignment. In the process of the pushing block 420 moving forward, under the linkage action of the clamping slide bar 452 and the clamping slide groove 431, the two clamping claws 451 can gradually move away from the pushing block 420 and loosen the chain unit, thereby completely connecting the chain unit on one side of the pushing block 420 to the spool, and the clearance hole 421 on the pushing block 420 provides a clearance space for the spool, which can further improve the stringing effect and have a high stringing yield.

[0047] It can be understood that the pushing drive mechanism 410 includes a pushing motor 411, an eccentric wheel 412, a slider 413, a slide rail 414 and a pushing tension spring 415. The pushing motor 411 and the slide rail 414 are both connected to the frame 100, the slide rail 414 is parallel to the extension direction of the spool, the eccentric wheel 412 is connected to the pushing motor 411, and the slider 413 is located on one side of the eccentric wheel 412. The motor is used to drive the eccentric wheel 412 to rotate and push the slider 413 to move close to the positioning plate 330 in a specified period. The pushing block 420 is connected to the side of the slider 413 close to the positioning plate 330. The two ends of the pushing tension spring 415 are respectively connected to the frame 100 and the slider 413, so that the slider 413 forms a movement trend away from the positioning plate 330, and the pushing block 420 synchronously follows the movement of the slider 413.

[0048] During operation, the pushing motor 411 drives the eccentric wheel 412 to rotate. In a specified period, the eccentric wheel 412 pushes the slider 413 to move closer to the positioning plate 330. At other times, the slider 413 moves away from the positioning plate 330 under the action of the pushing spring 415.

[0049] It can be understood that the slider 413 is rotatably connected to a push guide wheel 416, and the circumferential surface of the eccentric wheel 412 abuts against the circumferential surface of the push guide wheel 416. Through the push guide wheel 416, the wear between the eccentric wheel 412 and the slider 413 can be effectively reduced, and the stability of the structure during operation of the overall structure can be effectively improved.

[0050] It can be understood that the screening material disc 210 includes a fixed disc 212, a guide plate 213 and a rotating plate 214. The rotating plate 214 is rotatably connected to the fixed disc 212. The rotating plate 214 is located on the bottom surface of the internal space of the fixed disc 212. The rotating plate 214 is connected to the screening material driving mechanism 220. The circumferential surface of the rotating plate 214 is provided with a positioning groove 215 for accommodating the chain unit. A space for accommodating the chain unit is formed between the positioning groove 215 and the inner wall of the fixed disc 212. The screening material outlet 211 is provided on one side of the fixed disc 212. The screening material outlet 211 is located on the outside of the circumferential surface of the rotating plate 214. The guide plate 213 is located on the upper side of the rotating plate 214. One end of the guide plate 213 is connected to the screening material outlet 211. The guide plate 213 is used to guide the chain unit driven by the rotating plate 214 to the screening material outlet 211.

[0051] It can be understood that the chain supply assembly 200 also includes a storage bin 230, a feeding pipe 240, a feeding switch mechanism 250, a transfer drive mechanism 260 and a tipping mechanism 270. The storage bin 230 is connected to the frame 100, the feeding pipe 240 is connected to the outlet of the storage bin 230, the feeding switch mechanism 250 is connected to the feeding pipe 240, the feeding switch mechanism 250 is used to control the on and off of the feeding pipe 240, the tipping mechanism 270 is connected to the transfer drive mechanism 260, and the transfer drive mechanism 260 is used to drive the tipping mechanism 270 to move back and forth between the feeding pipe 240 and the fixed disk 212, so that the tipping mechanism 270 transfers the chain unit output by the feeding pipe 240 to the fixed disk 212. The storage bin 230 can be used to feed the fixed disk 212 online, which can effectively improve the overall working efficiency of the device.

[0052] It can be understood that the chain supply assembly 200 also includes a guide hopper 280 connected to the frame 100, the guide hopper 280 is located above the fixed plate 212, the tipping mechanism 270 includes a lifting plate 271, a transfer tipping hopper 272, a tipping spring 273, a tipping positioning block 274 and a tipping guide block 275, the lifting plate 271 is connected to the transfer drive mechanism 260, the transfer tipping hopper 272 is rotatably connected to the lifting plate 271, the tipping positioning block 274 is connected to the lifting plate 271, and the two ends of the tipping spring 273 are respectively connected to the transfer tipping hopper 272 and the lifting plate 271. So that the transfer tipping hopper 272 forms a movement tendency to rotate toward the tipping hopper positioning block 274. When the transfer tipping hopper 272 rotates and reaches the positioning block, the transfer tipping hopper 272 is placed horizontally, and the tipping guide block 275 is connected to the frame 100. The tipping guide block 275 is located on one side of the guide hopper 280. The tipping guide block 275 is arranged on the movement path of the tipping guide wheel near one end of the fixed plate 212. The tipping guide block 275 is used to drive the transfer tipping hopper 272 to rotate away from the tipping positioning block 274, thereby causing the transfer tipping hopper 272 to flip and dump the chain unit into the fixed plate 212.

[0053] During operation, the transfer drive mechanism 260 drives the lifting plate 271 to descend to the outlet of the feeding pipe 240, and the feeding switch mechanism 250 controls the conduction of the feeding pipe 240. The chain unit in the storage bin 230 is output to the transfer hopper 272 through the feeding pipe 240. Under the action of the hopper tension spring 273, the transfer hopper 272 is driven to abut against the hopper positioning block 274 and is in a horizontal position to effectively carry the chain unit; after the specified time, the feeding switch mechanism 250 controls the cut-off of the feeding pipe 240 to stop feeding, and the transfer drive mechanism 260 drives the lifting plate 271 to rise. When the transfer hopper 272 rises to the highest position, the side away from the hopper positioning block 274 is blocked by the hopper guide block 275, and the transfer hopper 272 rotates away from the positioning block so that the transfer hopper 272 pours the chain unit therein into the guide hopper 280 and falls into the fixed plate 212, and the feeding action is stable and reliable.

[0054] Specifically, the bucket guide wheel is rotatably connected to the transfer bucket 272. The bucket guide wheel replaces the transfer bucket 272 to contact the bucket guide block 275, which can effectively reduce the wear between the bucket guide block 275 and the transfer bucket 272 and effectively improve the service life of the bucket mechanism 270.

[0055] It can be understood that the feeding switch mechanism 250 includes a feeding cylinder 251 and a feeding baffle 252. The feeding cylinder 251 is connected to the frame 100, and the feeding baffle 252 is located between the feeding pipe 240 and the outlet of the storage bin 230.
