DETAILED DESCRIPTION

[0026] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should belong to the scope of protection of the present application.

[0027] According to the embodiment of the present application, a film feeding device is provided, please refer to Figures 4 to 6 , comprising: a film storage device 21, a grabbing mechanism 225 for grabbing the film from the outlet of the film storage device 21, and a swing mechanism 22 for driving the grabbing mechanism 225 to move from the outlet of the film storage device 21 to a film placement position, the film storage device 21 is provided with a transmission belt 24 for driving the film to move to the outlet, the transmission of the transmission belt 24 is driven by a driving shaft 25 connected with the transmission belt 24, 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 converted into the driving force of the driving shaft 25 through the linkage mechanism 23, wherein the linkage mechanism 23 comprises a first linkage rod 231, the swing mechanism 22 comprises a swing shaft 221 and a swing arm 222, the 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 driving the grabbing mechanism 225 at the film 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, and then drives the film on the transmission belt 24 to move. Through the linkage of the swing arm 222 and the driving shaft 25 through the first linkage rod 231, the swing of the swing arm 222 once, the driving shaft 25 rotates correspondingly, the grabbing of the film at the outlet of the film storage device 21 is matched with the movement of the film in the film storage device 21, and the working efficiency is improved. After the grabbing mechanism 225 of the film feeding device 2 grabs the film, the transmission belt 24 immediately moves the film on the transmission belt 24 a certain distance forward, ensuring that the grabbing mechanism 225 grabs the film at the outlet of the film storage device 21 next time.

[0028] As Figure 5As shown, the linkage mechanism 23 includes a first swing block 232 arranged on the swing shaft 221, the first swing block 232 is fixedly connected with the swing shaft 221, the first swing block 232 swings with the swing shaft 221, and 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 linkage mechanism 23 further includes a second swing block 233 arranged on the driving shaft 25, the other end of the first linkage rod 231 is hinged to the second swing block 233, the swing of the second swing block 233 is driven by the swing of the first linkage rod 231, and the second swing block 233 is connected with the driving shaft 25 through a reverse bearing, so that the swing action of the second swing block 233 drives the driving shaft 25 to rotate in one direction. Specifically, the first linkage rod 231 has the first swing block 232 and the second swing block 233 at two ends respectively, 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 present scheme is a cooperative action of multiple parts, the rotation angles or swing amplitudes of each part are accurately matched to jointly complete the feeding of the film. The reverse bearing drives the driving shaft 25 to rotate in only one direction, and then drives the film on the conveying belt 24 to move towards the outlet of the film storage device 21.

[0029] The first swing block 232 swings in the radial plane of the swing shaft 221, and the second swing block 233 swings in the radial plane of the driving shaft 25, wherein the distance from the hinging point of the first linkage rod 231 to the first swing block 232 to the axis of the swing shaft 221 is less than the distance from the hinging point of the first linkage rod 231 to the second swing block 233 to the axis of the driving shaft 25. Specifically, because the moving distance of the film conveyed by the conveying belt 24 to the outlet of the film storage device 21 is very small, the rotation angle of the driving shaft 25 is also smaller than the rotation angle of the swing shaft 221, and accordingly, the rotation angle of the driving shaft 25 is adjusted through the first swing block 232 and the second swing block 233, and further, when the grabbing mechanism 225 grabs a film, the driving shaft 25 drives the conveying 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.

[0030] The swing mechanism 22 drives the driving shaft 25 to rotate through the linkage mechanism 23 and the reverse bearing cooperation. The swing mechanism 22 completes one swing, and the angle of rotation of the driving shaft 25 is 10°. Further, because the swing mechanism 22 indirectly drives the driving shaft 25 to rotate in one direction, the driving shaft 25 rotates in one direction to drive the film on the transmission belt 24 to continuously move to the outlet of the film storage device 21. Specifically, the swing of the swing mechanism 22 and the rotation angle of the driving shaft 25 are adjusted to realize that the speed of the film moving to the outlet of the film storage device 21 matches the speed of the film being grabbed, thereby preventing the film from accumulating at the outlet of the film storage device 21 or the film from not reaching the outlet of the film storage device 21 when the grabbing mechanism 225 grabs the film.

[0031] A pressing plate 26 for aligning the upper end of the film is arranged at the outlet of the film storage device 21. The pressing plate 26 is located above the film and can move up and down to apply pressure to the film. The linkage mechanism 23 further includes a second linkage rod 234. One end of the second linkage rod 234 is hinged to the second swing block 233, and 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 through the swing, thereby driving the pressing plate 26 to move up and down. The pressing plate 26 is arranged at the outlet of the film storage device 21 and is connected with the second linkage rod 234 to realize the alignment of the upper surface of the film. Once the swing arm 222 swings, the film moves a certain distance to the outlet of the film storage device 21, and at the same time, the pressing plate 26 extrudes the upper end surface of the film once. The cooperation of each part makes the whole process more convenient and reduces the labor intensity of the operator.

[0032] As shown in Figure 7 The first linkage rod 231 includes a rod body and a connecting ring sleeve arranged at both ends of the rod body. The first swing block 232 and the second swing block 233 are respectively provided with ball heads 2312 at the hinge points of the first linkage rod 231. The connecting ring sleeves 2311 at both ends of the rod body are respectively sleeved on the ball heads 2312. The arrangement of the ball heads 2312 and the connecting ring sleeves 2311 first enables the connecting ring sleeves 2311 to contact the ball heads 2312 when the rod body is in action, has a certain angle adjustment space, and further enables the first linkage rod 231 to be conveniently disassembled.

[0033] The length of the first linkage rod 231 is adjustable. Specifically, the rod body of the first linkage rod 231 is composed of two screw rods connected through an outer pipe. The two screw rods are provided with external threads matched with internal threads. When the outer pipe rotates, the two screw rods simultaneously become longer or shorter, thereby realizing the length adjustment of the first linkage rod 231. Of course, the length of the second linkage rod 234 can also be set to be adjustable.

[0034] The film feeding device 2 further has a driving device 27, a connecting rod 28 is connected between the swing arm 222 and the driving device 27 and realizes power connection through the connecting rod 28, and the driving device 27 drives the swing arm 222 to swing through the connecting rod 28. The driving device 27 can be a motor, and the driving device 27 is the only power source of the film feeding device 2, and no additional power mechanism is needed to drive the transmission belt 24 to run.

[0035] As shown in Figure 6 The swing mechanism 22 includes a support 223 and a swing frame 224 pivotally connected with a free end of the swing arm 222, the support 223 is provided with an axle hole through which the swing shaft 221 passes, the swing shaft 221 rotates around the axle hole, the grabbing mechanism 225 is arranged on the swing frame 224 and moves with the swing frame 224, at least one end of the swing frame 224 is provided with a sliding rail 2241, the support 223 is connected with a sliding block 2242 corresponding to the sliding rail 2241, the sliding block 2242 can rotate around the connecting point, the swing arm 222 drives the swing frame 224 to move, and the grabbing mechanism 225 on the swing frame 224 realizes position switching under the cooperation of the sliding rail 2241 and the sliding block 2242. 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 placing position. Specifically, the swing arm 222 drives the swing frame 224, and the sliding block 2242 slides on the sliding rail 2241 back and forth, so as to realize the reciprocating movement of the swing frame 224.

[0036] The application further provides a sub-mother buckle processing equipment, as shown in Figure 3 The processing equipment further includes a rack 1, a transmission chain 11 arranged on the rack 1 to realize circulation transmission, and a sub-mother buckle plastic sheet feeding mechanism 3 arranged along the transmission direction of the transmission chain 11.
