[0022] When the plate is completely slid between the two brackets 604, the plate is dragged by the two brackets 604, and the edge of the plate abuts against the outer wall of the roller 712, so that the deflation rod 711 is pushed and the deflation rod 711 is pushed to flip, so that the deflation rod 711 pushes the stopper 710, so that the stopper 710 pulls the push rod 708, thereby driving the sealing plate 709 to slide inside the valve body 706, so that the side air inlet 707 and the through hole 713 are in a connected state. At this time, the weight of the sliding frame 601 and other parts and the weight of the plate are applied to the top of the support rod 703, so that the support rod 703 pushes the second piston 702 to slide downward. The second piston 702 compresses the air inside the sleeve 701 into the valve body 706 through the side air inlet 707, and then passes through the through hole 71 3 is discharged. During the descending process of the second piston 702, the sliding frame 601 also slides downward on the inner wall of the outer frame 1, thereby driving the plate to slide downward, so that the roller 712 rolls on the side wall of the plate. When the sliding frame 601 slides downward for a certain distance, the plate is separated from the roller 712. At this time, the deflation rod 711 is reset under the push of the torsion spring, so that the sealing plate 709 is reset under the drive of the air flow inside the valve body 706, and the sealing plate 709 is tightly fitted with the inner wall of the valve body 706 under the action of air pressure, so that the air inside the sleeve 701 cannot continue to be discharged, so that the second piston 702 and the support rod 703 cannot continue to slide downward, so that the sliding frame 601 cannot bring the plate down. The height of the plate dropped in the above process is just slightly greater than its own thickness. After the next group of plates is pushed between the two groups of sliding frames 601, the above process is repeated again, and the second group of plates is located at the top of the first group of plates, achieving the effect of automatic stacking.

[0023] Please refer to Figure 2 , Figure 3 , Figure 6 , Figure 8 and Fig. 9The tops of the two groups of sliding frames 601 are respectively fixedly connected to multiple groups of motors 602, and the output ends of each group of motors 602 are respectively fixedly connected to a group of rotating rods 603, the bottom ends of the multiple groups of rotating rods 603 are rotatably connected to a bracket 604, and the side walls of the bracket 604 are slidably connected to a pressure plate 605, and the bottom end of the bracket 604 is rotatably connected to multiple groups of rotating rods 603, and the multiple groups of rotating rods 603 at the bottom of the bracket 604 are in a parallel state with the multiple groups of rotating rods 603 at the top of the bracket 604, and the ends of the multiple groups of rotating rods 603 at the bottom of the bracket 604 are rotatably connected to the bottom end of the inner wall of the sliding frame 601, and the inner wall sliding sleeve of the air storage chamber 606 is provided with a first piston 607, the top of the first piston 607 is fixedly connected with a pull rod 608, one end of the pull rod 608 located outside the air storage chamber 606 is fixedly connected with a blocking rod 609, one end of the blocking rod 609 is slidably connected to the side wall of the sliding frame 601, the other end of the blocking rod 609 extends to the top of the pressure plate 605, the top of the blocking rod 609 is fixedly connected with a return spring 610, the top of the return spring 610 is fixedly connected to the top of the sliding frame 601, a front conveyor belt 2 is fixedly provided on one side of the outer frame 1, a rear conveyor belt 5 is fixedly provided on the other side of the outer frame 1, two groups of pressure rollers 3 are provided above the front conveyor belt 2, and a plurality of groups of support rollers 4 are hinged to the top of the outer frame 1.

[0024] As more and more plates are pushed between the two sets of sliding racks 601, the height of the sliding rack 601 is continuously lowered. As the number of stacked plates increases, the height of the pressure plate 605 sliding upward on the side wall of the sliding rack 601 is also increasing, so that the edge of the pressure plate 605 abuts against the bottom end of the blocking rod 609. After more and more plates are pushed between the two sets of sliding racks 601, the height of the pressure plate 605 is getting higher and higher, so that the blocking rod 609 is pushed upward, so that the blocking rod 609 compresses the return spring 610 and drives the pull rod 608 to slide upward, so that the pull rod 608 drives the first piston 607 to slide upward, so that negative pressure is generated inside the air storage chamber 606, so that the second one-way valve 614 opens and the first one-way valve 612 is tightly closed under the action of air pressure, thereby sucking outside air into the air storage tank. When the sliding rack 601 slides to the bottom, the second piston 702 appears inside the sleeve 701 as shown in the figure. Fig. 9The state is in the middle, and the lowest plate is located at the top of the support roller 4, and the gap between the two is very small. At this time, the motor 602 starts to rotate and drives the rotating rod 603 located above the bracket 604 to rotate. The multiple groups of rotating rods 603 rotate synchronously, so that the bracket 604 approaches the direction of the rear conveyor belt 5, so that part of the plate moves to the top of the rear conveyor belt 5, and with the rotation of the rotating rod 603, the distance between the two groups of brackets 604 is separated from each other, so that the two groups of brackets 604 are separated from the plate. At this time, the stacked plate falls on the top of the support roller 4, so that the rear conveyor belt 5 pulls the plate , the plate is transported to the specified position. After the plate is separated from the bracket 604, the return spring 610 rebounds, so that the stop rod 609 is reset, and the pressure plate 605 falls and resets. At this time, the first piston 607 slides downward inside the air storage chamber 606, pushing the air inside the air storage chamber 606 into the sleeve 701, thereby pushing the first one-way valve 612 to open and the third one-way valve 704 to open, while the second one-way valve 614 is closed. After the air enters the sleeve 701, it pushes the second piston 702 to slide upward, so that the support rod 703 rises, thereby driving the sliding frame 601 to reset, so that the sliding frame 601 is reset to Figure 2 The motor 602 drives the rotating rod 603 to rotate 360 ​​degrees and then stops rotating, so that the distance between the two groups of brackets 604 returns to the initial state.

[0025] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The side wall of the outer frame 1 is fixedly connected with a protective mechanism 8, which includes a film coil 801, and the outer wall of the film coil 801 is fixedly connected with a plurality of groups of rubber strips 802, the film coil 801 is slidably sleeved on the side wall of the outer frame 1, and the side wall of the outer frame 1 is fixedly connected with a guide frame 803, and the guide frame 803 is slidably sleeved on the outer wall of the film coil 801, and the side wall of the guide frame 803 is fixedly connected with an elastic sheet 804, and the elastic sheet 804 is attached to the side wall of the film coil 801, and the side wall of the guide frame 803 is fixedly connected with two groups of outer cylinders 807, and one end of the two groups of outer cylinders 807 is respectively connected to a group Through hole 713, an upper exhaust hole 811 is opened on the side wall of the outer cylinder 807, a third piston 808 is provided on the inner wall sliding sleeve of the outer cylinder 807, a push rod 809 extending to the outer cylinder 807 is fixedly connected to the side wall of the third piston 808, and a sliding rod 810 is fixedly connected to one end of the push rod 809 located outside the outer cylinder 807, a group of rotating arms 805 are rotatably connected to both sides of the guide frame 803, and a torsion spring is arranged at the connection between the rotating arms 805 and the guide frame 803, the top sliding sleeves of the two groups of rotating arms 805 are provided with sliding rods 810, and an electric heating cutting wire 806 is fixedly connected between the two groups of rotating arms 805.

[0026] In the process of each group of plates being pushed between the two groups of brackets 604, the plates pass under the elastic sheet 804, and the elastic force of the elastic sheet 804 makes the film fit tightly with the plates, so that the rubber strip 802 on the mat adheres to the top of the plates, so that the film is pulled in the process of the plates moving forward, so that the film in the film roll 801 is unfolded and adheres to the top of the plates under the action of the elastic sheet 804, and the spacing between the rubber strips 802 matches the length of the plates. Then, each time air is discharged from the through hole 713, the air enters the outer cylinder 807, thereby pushing the third piston 808 to slide inside the outer cylinder 807, and the third piston 808 The push rod 809 is driven to slide toward the outside of the sleeve 701, so that the push rod 809 drives the sliding rod 810 to move, thereby pushing the rotating arm 805 to flip. During the flipping process of the two sets of rotating arms 805, the electric heating cutting wire 806 is driven to cut the film. When the third piston 808 slides to the end inside the outer cylinder 807, the upper exhaust hole 811 is no longer blocked by the third piston 808, so that air is discharged from the upper exhaust hole 811, and then the torsion spring rebounds to push the rotating arm 805 to reset, and the rotating arm 805 pushes the sliding rod 810 to reset, so that the sliding rod 810 pushes the push rod 809 to reset, and the push rod 809 pushes the third piston 808 to slide in the opposite direction inside the outer cylinder 807 to reset.

[0027] When in use, after the plate is pushed between the two groups of brackets 604 by the front conveyor belt 2, the end of the plate abuts against the roller 712, so that the sliding frame 601 descends, and the plate also descends with the sliding frame 601, so that the plate and the roller 712 are separated. At this time, the sliding frame 601 no longer continues to descend. The thicker the plate, the higher the sliding frame 601 descends. In the process of stacking, the height can be adaptively adjusted according to different plate thicknesses, so that when performing stacking, there is no need to adjust the equipment separately according to the plate thickness, making the stacking and conveying equipment more convenient to use, improving work efficiency and reducing work intensity. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
