[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] According to an embodiment of the present invention, a feeding device for a plastic sheet of a snap fastener is provided. Figures 4 to 8 , including: a feeding device 31, a gluing device 36 and a loading grabbing device 32, the feeding device 31 includes a feeding track for realizing the feeding of the snap fastener plastic sheets one by one, the loading grabbing device 32 is arranged at the end of the feeding track to grab the snap fastener plastic sheets at the end of the feeding track for loading, the gluing device 36 is arranged on the moving path of the loading grabbing device 32, the loading grabbing device 32 grabs the snap fastener plastic sheets at the end of the feeding track and then moves to the gluing device 36 to complete the gluing action for loading. When the device is running, the feeding device 31, the gluing device 36 and the loading grabbing device 32 work together to put the snap fastener plastic sheets into the loading position, without the need for operator intervention throughout the process, and the snap fastener plastic sheets can be loaded uniformly and directionally, reducing the error rate and improving production efficiency.

[0030] like Figure 7-8As shown, the feeding device 31 includes a vibrating screen plate 311, and the vibrating screen plate 311 includes a spiral upward queuing track 3111 for realizing the queueing and conveying of the sub-fastener plastic sheets one by one, and a screening track 3112 for screening the postures of the queued and conveyed sub-fastener plastic sheets, the end of the queuing track 3111 is connected to the starting end of the screening track 3112, and the connection between the end of the queuing track 3111 and the starting end of the screening track 3112 is provided with a flipping structure 33 for realizing the sub-fastener plastic sheets from a lying posture to a standing posture, the end of the queuing track 3111 is arranged on one side of the flipping structure 33 and connected to the top of the flipping structure 33, and the starting end of the screening track 3112 is arranged on the other side of the flipping structure 33 and connected to the bottom of the flipping structure 33. During operation, the snap-on plastic sheet is located inside the vibrating screen plate 311. At this time, the snap-on plastic sheet is in a disordered state. First, the vibration of the vibrating screen plate 311 drives the disordered snap-on plastic sheet to spiral upward along the queuing track 3111. The snap-on plastic sheet on the queuing track 3111 is in a lying position. When the snap-on plastic sheet in a lying position reaches the end of the queuing track 3111, it changes from a lying position to a standing position through the flip structure 33. Specifically, the queuing track 3111 and the screening track 3112 are not on the same horizontal plane. The top of one side of the flip structure 33 is connected to the queuing track 3111, and the bottom of the other side of the flip structure 33 is connected to the screening track 3112, so that the snap-on plastic sheet is flipped from the queuing track 3111 to the screening track 3112. At this time, the snap-on plastic sheet in a lying position is turned into a snap-on plastic sheet in a standing position after flipping, and the redundant snap-on plastic sheet that has not changed into a standing position will fall from the screening track 3112.

[0031] like Figure 7 As shown, the screening track 3112 is composed of an inner track 341 and an outer track 342, and a walking gap is formed between the inner track 341 and the outer track 342 for the sub-fastener plastic sheet to be transported in a standing posture, wherein the top of the inner track 341 is higher than the height of the top of the outer track 342, and the width of the walking gap is greater than the thickness of the sub-fastener plastic sheet and less than the convex part of the sub-fastener plastic sheet and the overall thickness of the sheet. When the sub-fastener plastic sheet in a standing posture enters the starting end of the screening track 3112, the convex part of the sub-fastener plastic sheet is some toward the outside of the vibrating screen plate 311, and some toward the inside of the vibrating screen plate 311. When the sub-fastener plastic sheet with the convex part facing the outside of the vibrating screen plate 311 moves forward on the walking gap, the back of the sub-fastener plastic sheet just fits the inner track 341 and moves forward. One end of the sub-fastener plastic sheet is stuck in the walking gap and can be stably transported forward, while the sub-fastener plastic sheet with the convex part facing the inside of the vibrating screen plate 311 will fall when moving forward on the walking gap, and a screening is completed at this time.

[0032] Specifically, the flip structure 33 is composed of an arc panel 331 located on the inner side and a baffle 332 located on the outer side. The bottom of the arc panel and the bottom of the baffle 332 gradually approach to form a flared structure. The bottom of the arc panel 331 is connected to the starting end of the inner track 341 of the screening track 3112, and the bottom of the baffle 332 is connected to the starting end of the outer track 342 of the screening track 3112. When the snap-on plastic sheet slides off the arc panel 331, it touches the baffle 332. Due to the resistance of the baffle 332, the snap-on plastic sheet changes to a standing posture when flipping. Further, the bottom of the arc panel and the bottom of the baffle 332 gradually approach to form a 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, so as to prevent the snap-on plastic sheet from falling when flipping, so that the snap-on plastic sheet can accurately enter the screening track 3112 in a standing posture. The connection between the arc panel 331 and the starting end of the inner track 341 is located at the 2 / 3 of the outer side of the center line of the end queuing track 3111. The top 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. The setting here further improves the accuracy of screening and ensures that the snap-on plastic sheets efficiently enter the screening track 3112 and are transported forward.

[0033] A screening rod 35 is also provided above the screening track 3112 for screening the snap-on plastic sheets based on the different standing states on the screening track 3112. The bottom end of the screening rod 35 is arranged close to the inner track 341, and the top end of the screening rod 35 extends from the bottom end to the outside of the screening track 3112, and the extension degree exceeds the position of the outer track 342, wherein the distance between the screening rod 35 and the outer track 342 is less than the length of the snap-on plastic sheet, and greater than the width of the snap-on plastic sheet. Some of the snap-on plastic sheets standing on the screening track 3112 have their long sides located in the walking gap, and some of the snap-on plastic sheets have their wide sides located in the walking gap. This scheme selects snap-on plastic sheets whose long sides are located in the walking gap. Therefore, a screening rod 35 is provided on the screening track 3112, and the distance between the screening rod 35 and the outer track 342 is set. When the distance between the screening rod 35 and the outer track 342 is less than the length of the snap-on plastic sheet, and greater than the width of the snap-on plastic sheet, The plastic sheets of the snap fasteners whose wide sides are located in the walking gap have a standing height higher than the screening rod 35, and the screening rod 35 will automatically peel off the plastic sheets of the snap fasteners whose wide sides are located in the walking gap from the screening track 3112. The plastic sheets of the snap fasteners whose long sides are located in the walking gap have a standing height lower than the screening rod 35, and can be upright and continue to be transported forward through the screening rod 35 to complete the secondary screening. The screened plastic sheets of the snap fasteners are matched with the gluing device 36 and the feeding device, and can be automatically fed without the need for operator adjustment.

[0034] like Figure 5As shown, the feed track includes a distributor 312 for realizing the sub-track transmission of the snap fastener plastic sheets, the distributor 312 includes distribution tracks 3121 twice the number of the feed tracks and a distribution mechanism 3122 for distributing the snap fastener plastic sheets to the distribution track 3121, the inlet of the distribution track 3121 is connected to the end of the screening track 3112, and the distribution mechanism 3122 is arranged at the inlet of the distribution track 3121. The snap fastener plastic sheets screened out at the end of the screening track 3112 enter each distribution track 3121 through the distributor 312, on the one hand, preventing the snap fastener plastic sheets from stacking at the end of the screening track 3112, and on the other hand, matching the glue coating device 36 and the feeding grabbing device 32, the snap fastener plastic sheets output simultaneously at the end of the distribution track 3121 can be grabbed by the feeding grabbing device 32 at the same time, which greatly improves the work efficiency.

[0035] Specifically, the distribution mechanism 3122 includes a distribution plate and a distribution cylinder for driving the distribution plate to move. A distribution space for accommodating the distribution plate is set at the connection between the distribution track 3121 and the screening track 3112. The distribution plate can move left and right along the distribution space. A pushing structure is set at the bottom of the distribution plate. After the sub-fastener plastic sheet transported by the screening track 3112 enters the distribution space, the distribution plate moves driven by the distribution cylinder and pushes the sub-fastener plastic sheet in the distribution space through the pushing structure to a position corresponding to a certain distribution track 3121 opening.

[0036] Specifically, there are four distribution tracks 3121, which are arranged side by side and tilted downward, and the distribution mechanism 3122 distributes the snap-on plastic sheets at the end of the screening track 3112 to the inlets of the four distribution tracks 3121. Two vibrating screen plates 311 are provided, and at this time, there are four distribution tracks 3121. Driven by an external distribution motor, the distribution mechanism 3122 moves left and right along the distribution space of the four distribution tracks 3121.

[0037] like Figure 5-6As shown, the loading and grabbing device 32 includes a bracket 321, a first driving mechanism 322 that drives the bracket 321 to slide back and forth between the gluing position and the loading position, a first grabbing mechanism 325 and a second grabbing mechanism 324 arranged on both sides of the bracket 321 along the layout direction of the loading position, the first grabbing mechanism 325 and the second grabbing mechanism 324 are driven by the second driving mechanism 323 arranged on the bracket 321 to move up and down, during the reciprocating sliding process of the bracket 321, the first grabbing mechanism 325 grabs the snap-on plastic sheet at the end of the feeding track to the gluing device 36, and the second grabbing mechanism 324 grabs the snap-on plastic sheet in the gluing device 36 to the loading position. A slide rail 3211 and a slider 3212 are arranged at the bottom of the bracket 321, the slider 3212 is connected to the first driving mechanism 322, the slide rail 3211 and the slider 3212 are arranged correspondingly, and the reciprocating motion of the bracket 321 is realized under the cooperation of the slide rail 3211 and the slider 3212. A first grabbing mechanism 325 and a second grabbing mechanism 324 are simultaneously arranged on the bracket 321. When the bracket 321 is located at the gluing position, the first grabbing mechanism 325 grabs the snap-on plastic sheet at the end of the feeding track, and the second grabbing mechanism 324 grabs the snap-on plastic sheet in the gluing device 36. When the bracket 321 slides from the gluing position to the loading position, at the loading position, the second grabbing mechanism 324 puts the grabbed snap-on plastic sheet in the gluing device 36 into the loading position, and the first grabbing mechanism 325 puts the grabbed snap-on plastic sheet at the end of the feeding track into the gluing device 36. During the reciprocating motion of the bracket 321, the first grabbing mechanism 325 grabs the snap-on plastic sheet at the end of the feeding track to the gluing device 36, and the second grabbing mechanism 324 grabs the snap-on plastic sheet in the gluing device 36 to the loading position.

[0038] The glue coating device 36 includes a glue coating plate and a glue injection structure for injecting glue into the glue coating plate. The glue coating plate is provided with a glue coating groove that matches the shape of the snap buckle plastic sheet. The glue injection structure injects glue into the glue coating groove. The feeding and grabbing device 32 grabs the snap buckle plastic sheet output by the feeding device 31 into the glue coating groove of the glue coating device 36 to achieve gluing. The glue coating device 36 of this solution is simple and convenient. The feeding and grabbing device 32 places the snap buckle plastic sheet in the glue coating groove to achieve gluing.

[0039] A lifting plate 3213 is disposed on the bracket 321 . The second driving mechanism 323 is connected to the lifting plate 3213 and drives the lifting plate 3213 to move up and down. The first grabbing mechanism 325 and the second grabbing mechanism 324 are disposed on the lifting plate 3213 .

The snap buckle processing equipment can realize automatic film feeding through the film feeding device 2, making the whole process easier to operate and reducing the labor intensity of the operator.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
