The swing mechanism 22 is connected with the driving shaft 25 through a linkage mechanism 23 to realize linkage. The action of the swing mechanism 22 is transmitted and converted into the driving force of the driving shaft 25 through the linkage mechanism 23. The linkage mechanism 23 comprises a first linkage rod 231. The swing mechanism 22 comprises a swing shaft 221 and a first swing arm 222. The first swing arm 222 is fixedly connected with the swing shaft 221. One end of the first linkage rod 231 is connected with the swing shaft 221. The swing of the first linkage rod 231 at this end is driven by the action of the swing shaft 221. The other end of the first linkage rod 231 is connected with the driving shaft 25. The swing of the first linkage rod 231 at this end drives the rotation of the driving shaft 25. During the reciprocating movement of the swing mechanism 22 and the grabbing mechanism 225 at the plastic sheet grabbing position and the placement position, the driving shaft 25 is linked with the action of the swing mechanism 22 under the action of the linkage mechanism 23. The driving shaft 25 rotates under the action of the linkage mechanism 23, thereby driving the plastic sheets on the transmission belt 24 to move. Through the linkage of the first swing arm 222 and the driving shaft 25 through the first linkage rod 231, the first swing arm 222 swings once, and the driving shaft 25 rotates correspondingly, thereby realizing the grabbing of the plastic sheets at the outlet of the plastic sheet storage device 21 and matching the movement of the plastic sheets in the plastic sheet storage device 21, and improving the work efficiency.

Specifically, the two ends of the first linkage rod 231 are respectively provided with the first swing block 232 and the second swing block 233, and the linkage amplitude between the swing shaft 221 and the driving shaft 25 is conveniently controlled through the first swing block 232 and the second swing block 233, because the film feeding device 2 is a plurality of parts that act cooperatively, therefore, the rotation angle or swing amplitude of each part is accurately matched to jointly complete the feeding of the film. The reverse bearing functions to drive the driving shaft 25 to rotate in only one direction, thereby driving the film on the transmission belt 24 to move towards the outlet of the film storage device 21. In addition, the moving distance of the film transported by the transmission belt 24 to the outlet of the film storage device 21 is very small, therefore, the rotation angle of the driving shaft 25 is also smaller than the rotation angle of the swing shaft 221, accordingly, the rotation angle of the driving shaft 25 is adjusted through the first swing block 232 and the second swing block 233, further, when the grabbing mechanism 225 grabs a film, the driving shaft 25 drives the transmission belt 24 to move forward by a distance of one film thickness, and the grabbing of the film and the forward supply of the film are matched.

The swing mechanism 22 drives the grabbing mechanism 225 to reciprocate to complete the transfer from the outlet of the film storage device 21 to the film placement position. Specifically, the first swing arm 222 drives the swing frame 224, and at the same time the first sliding block slides back and forth on the first sliding rail, realizing the reciprocating movement of the swing frame 224.

[0038] As shown in the figure, Figures 4-6As shown, the snap buckle plastic sheet feeding device 3 comprises a feeding device 31, a gluing device 36 and a snap buckle plastic sheet feeding grabbing device 32. The feeding device 31 comprises a feeding track for realizing the one-by-one queuing feeding of the snap buckle plastic sheets. The snap buckle plastic sheet feeding grabbing device 32 is arranged at the end of the feeding track to grab the snap buckle plastic sheet at the end of the feeding track for feeding.

After the snap buckle plastic sheet feeding grabbing device 32 grabs the snap buckle plastic sheet at the end of the feeding track, it moves to the gluing device 36 to complete the gluing action and then feeds. During the operation of the device, the feeding device 31, the gluing device 36 and the snap buckle plastic sheet feeding grabbing device 32 work together to realize the placement of the snap buckle plastic sheet to the feeding position. The whole process does not need the intervention of the operator. The feeding of the snap buckle plastic sheet can be unified and directional, which reduces the failure rate and improves the production efficiency.

[0039] As Figures 7-8As shown, the feeding device 31 comprises a vibrating sieve tray 311, which comprises a spiral upward queuing track 3111 for realizing the one-by-one queuing conveying of the snap hook plastic sheets and a screening track 3112 for screening the posture of the queuing conveyed snap hook plastic sheets, the end of the queuing track 3111 is connected with the starting end of the screening track 3112, and a turnover structure 33 for realizing the turning of the snap hook plastic sheets from the lying posture to the standing posture is arranged at the connection position of the end of the queuing track 3111 and the starting end of the screening track 3112, the end of the queuing track 3111 is arranged on one side of the turnover structure 33 and connected with the top of the turnover structure 33, and the starting end of the screening track 3112 is arranged on the other side of the turnover structure 33 and connected with the bottom of the turnover structure 33; the screening track 3112 is composed of an inner track 341 and an outer track 342, and a walking gap for conveying the snap hook plastic sheets in the standing posture is formed between the inner track 341 and the outer track 342, wherein the top end of the inner track 341 is higher than the top end of the outer track 342, and the width of the walking gap is greater than the thickness of the sheet body of the snap hook plastic sheet and less than the thickness of the convex part and the whole sheet body of the snap hook plastic sheet; the turnover structure 33 is composed of an arc panel 331 on the inner side and a baffle 332 on the outer side, the bottom of the arc panel 331 and the bottom of the baffle 332 gradually approach each other to form a flared structure, the bottom of the arc panel 331 is connected with the starting end of the inner track 341 of the screening track 3112, and the bottom of the baffle 332 is connected with the starting end of the outer track 342 of the screening track 3112. When working, the snap hook plastic sheets are located in the interior of the vibrating sieve tray 311, at this time, the snap hook plastic sheets are in a disordered state, first, the vibration of the vibrating sieve tray 311 drives the disordered snap hook plastic sheets to move upward along the queuing track 3111, the snap hook plastic sheets on the queuing track 3111 are in a lying posture, and the lying posture snap hook plastic sheets become standing posture snap hook plastic sheets through the turnover structure 33 when reaching the end of the queuing track 3111. Specifically, the queuing track 3111 and the screening track 3112 are not in the same horizontal plane, the top of one side of the turnover structure 33 is connected with the queuing track 3111, and the bottom of the other side of the turnover structure 33 is connected with the screening track 3112, so as to realize the turnover of the snap hook plastic sheets from the queuing track 3111 to the screening track 3112, at this time, the lying posture snap hook plastic sheets become standing posture snap hook plastic sheets after turnover, and the excess or not standing posture snap hook plastic sheets will fall off from the screening track 3112.The standing posture of the buckle plastic piece enters the starting end of the screening track 3112, and the convex part of the buckle plastic piece is directed outward or inward of the vibrating screen disc 311. The buckle plastic piece with the convex part directed outward of the vibrating screen disc 311 is forwarded on the walking gap, and the back of the buckle plastic piece is just fitted to the inner track 341. The end of the buckle plastic piece is clamped into the walking gap to stably forward, and the buckle plastic piece with the convex part directed inward of the vibrating screen disc 311 is dropped when forwarded on the walking gap, and the screening is completed. When the buckle plastic piece slides off the arc panel 331, the buckle plastic piece is touched by the baffle 332, and the buckle plastic piece is changed to the standing posture when turned over due to the resistance of the baffle 332. Further, the bottom of the arc panel and the bottom of the baffle 332 gradually approach to the flared structure, and the bottom of the arc panel 331 is connected to the starting end of the inner track 341 of the screening track 3112 to avoid the buckle plastic piece from falling when turned over, so that the buckle plastic piece can accurately enter the screening track 3112 in the standing posture. The connection between the arc panel 331 and the starting end of the inner track 341 is located at the outer 2 / 3 of the middle line of the final queuing track 3111. The top end of the baffle 332 is higher than the top of the arc panel 331, and the end of the baffle 332 protrudes from the end of the arc panel 331, which further improves the accuracy of screening and ensures that the buckle plastic piece efficiently enters the screening track 3112 for forwarding.

[0040] The screening rail 3112 is further provided with a screening rod 35 for screening the mother and child buckle plastic pieces in different standing states on the screening rail 3112. The bottom end of the screening rod 35 is arranged close to the inner rail 341, and the top end of the screening rod 35 extends from the bottom end to the outside of the screening rail 3112, and the extending degree exceeds the position of the outer rail 342. The distance between the screening rod 35 and the outer rail 342 is less than the length of the mother and child buckle plastic piece body and greater than the width of the mother and child buckle plastic piece body. The long edges of some mother and child buckle plastic piece bodies in the standing state on the screening rail 3112 are located in the walking gap, and the wide edges of some mother and child buckle plastic piece bodies are located in the walking gap. The present scheme selects the mother and child buckle plastic pieces with the long edges of the piece bodies located in the walking gap. Therefore, the screening rod 35 is arranged on the screening rail 3112, and the distance between the screening rod 35 and the outer rail 342 is set. When the distance between the screening rod 35 and the outer rail 342 is less than the length of the mother and child buckle plastic piece body and greater than the width of the mother and child buckle plastic piece body, the mother and child buckle plastic pieces with the wide edges of the piece bodies located in the walking gap are automatically stripped from the screening rail 3112 by the screening rod 35 due to the standing posture height being higher than the screening rod 35. The mother and child buckle plastic pieces with the long edges of the piece bodies located in the walking gap can stand through the screening rod 35 and continue to be conveyed forward to complete the secondary screening. The screened mother and child buckle plastic pieces are matched with the gluing device 36 and the feeding device, and do not need to be adjusted by the operator to automatically feed.

[0047] The full-automatic mother and daughter buckle machine of the present application will be described in detail below in combination with the embodiments. After the machine is started, the film feeding device 2 and the mother and daughter buckle plastic sheet feeding device 3 work simultaneously.

[0048] Firstly, for the film feeding device 2, the driving device 27 of the film feeding device 2 is a driving motor, the driving motor drives the first swing arm 222 to swing through the connecting rod 28, the first swing arm 222 is fixedly connected with the swing shaft 221 to drive the swing shaft 221 to rotate, the swing shaft 221 is fixedly connected with the first swing block 232, thus the first swing block 232 swings with the rotation of the swing shaft 221, one end of the first linkage rod 231 is hinged to the first swing block 232 to realize the connection with the swing shaft 221, the other end of the first linkage rod 231 is hinged to the second swing block 233, the swing of the first linkage rod 231 drives the swing of the second swing block 233, the second swing block 233 is connected with the driving shaft 25 through the reverse bearing, so that the swing of the second swing block 233 drives the unidirectional rotation of the driving shaft 25, and then drives the film on the transmission belt 24 to move. One end of the second linkage rod 234 is hinged to the second swing block 233, the other end of the second linkage rod 234 is hinged to the pressing plate 26, the second swing block 233 drives the second linkage rod 234 to swing, and then drives the pressing plate 26 to move up and down to realize the alignment of the upper surface of the film. The driving motor drives the first swing arm 222 to swing through the connecting rod 28, the swing frame 224 is pivoted to the free end of the first swing arm 222, the first swing arm 222 drives the swing frame 224 to swing, and realizes the switching of the position of the second suction cup on the swing frame 224 under the cooperation of the first sliding rail and the first sliding block.

[0049] Secondly, for the sub-mother buckle plastic sheet feeding device 3, the vibration of the vibrating sieve tray 311 drives the disordered sub-mother buckle plastic sheet to spiral upward along the queuing track 3111. The queuing track 3111 is not in the same horizontal plane as the screening track 3112. The top of one side of the turnover structure 33 is connected with the queuing track 3111, and the bottom of the other side of the turnover structure 33 is connected with the screening track 3112. The turnover structure 33 is composed of an arc surface plate 331 located on the inner side and a baffle 332 located on the outer side. The bottom of the arc surface plate and the bottom of the baffle 332 gradually approach to form a flared structure, and the bottom of the arc surface plate 331 is connected with the starting end of the inner track 341 of the screening track 3112. When the sub-mother buckle plastic sheet slides off the arc surface plate 331, it touches the baffle 332, and the sub-mother buckle plastic sheet becomes a standing posture due to the resistance of the baffle 332. When the standing posture sub-mother buckle plastic sheet enters the starting end of the screening track 3112, the protruding part of the sub-mother buckle plastic sheet is directed outward or inward from the vibrating sieve tray 311. The sub-mother buckle plastic sheet with the protruding part directed outward advances on the walking gap, and the back of the sub-mother buckle plastic sheet is just fitted to the inner track 341 for forward movement. The end of the sub-mother buckle plastic sheet body is clamped in the walking gap to stably forward, while the sub-mother buckle plastic sheet with the protruding part directed inward falls on the walking gap, and the screening is completed at this time. The screening track 3112 is further provided with a screening rod 35 for screening based on the different standing states of the sub-mother buckle plastic sheet on the screening track 3112. The distance between the screening rod 35 and the outer track 342 is set to be less than the length of the sub-mother buckle plastic sheet body and greater than the width of the sub-mother buckle plastic sheet body. When the width of the sub-mother buckle plastic sheet body is located in the walking gap, the standing posture height is higher than the screening rod 35, and the screening rod 35 automatically peels off the sub-mother buckle plastic sheet with the width of the body located in the walking gap from the screening track 3112. The sub-mother buckle plastic sheet with the length of the body located in the walking gap can stand through the screening rod 35 to continue to forward, and the secondary screening is completed. After the secondary screening is completed, the sub-mother buckle plastic sheet continues to advance, passes through the distribution mechanism from the end of the screening track 3112, and enters four inclined distribution tracks 3121. The distribution plate can move left and right along the distribution space. The bottom of the distribution plate is provided with a pushing structure. After the sub-mother buckle plastic sheet fed by the screening track 3112 enters the distribution space, the distribution plate moves under the drive of the distribution cylinder and pushes the sub-mother buckle plastic sheet in the distribution space to a position corresponding to the mouth of a certain distribution track 3121 through the pushing structure. The sub-mother buckle plastic sheet is grabbed by the first sub-mother buckle plastic sheet grabbing mechanism 325 at the end of the distribution track 3121.When the support frame 321 is located at the gluing position, the first sub-male buckle plastic sheet grabbing mechanism 325 grabs the sub-male buckle plastic sheet at the end of the feeding track, and the second sub-male buckle plastic sheet grabbing mechanism 324 grabs the sub-male buckle plastic sheet in the gluing device 36. When the support frame 321 slides from the gluing position to the feeding position, at the feeding position, the second sub-male buckle plastic sheet grabbing mechanism 324 places the grabbed sub-male buckle plastic sheet in the gluing device 36 to the feeding position, and the first sub-male buckle plastic sheet grabbing mechanism 325 places the grabbed sub-male buckle plastic sheet at the end of the feeding track to the gluing groove. During the reciprocating movement of the support frame 321, the first sub-male buckle plastic sheet grabbing mechanism 325 grabs the sub-male buckle plastic sheet at the end of the feeding track to the gluing groove, and the second sub-male buckle plastic sheet grabbing mechanism 324 grabs the sub-male buckle plastic sheet in the gluing groove to the feeding position.

[0050] The film feeding device 2 delivers the films one by one to the tools at the film feeding position, where four tools form a group, and the sub-male buckle plastic sheet feeding device 3 completes the gluing of the sub-male buckle plastic sheet one by one and delivers them to the tools at the sub-male buckle plastic sheet feeding position, thereby completing the combination of the film and the sub-male buckle plastic sheet, with the film below and the sub-male buckle plastic sheet above.

[0051] After the combination of the film and the sub-male buckle plastic sheet, the tools are sequentially transported to the curing device along the transmission chain 11 circulating on the rack 1, and after unloading, the sub-male buckle finished product falls into the finished product placement area. After unloading, the tools are brought back to the starting position by the transmission chain 11 for the next cycle of production.
