Traditional manual stacking methods are labor-intensive, low-efficiency, and difficult to ensure the stability and consistency of stacking, Existing automatic stacking equipment is prone to deviation or accumulation during paper box conveying, resulting in subsequent clamping and stacking failure. Some existing equipment uses fixed baffles for limiting, but cannot be dynamically adjusted, which can cause paper box jamming or poor feeding. During the lifting of the paper box, the traditional equipment often lacks effective anti-interference measures, which can cause the subsequent paper box to enter the lifting area, affecting the resetting of the feeding plate. In addition, the moving track of the clamping mechanism is single, and it is difficult to adapt to the precise grabbing of paper boxes of different sizes. SUMMARY

A threaded rod 105 is fixedly installed at one end of the rotating rod 104. Two round rods 124 are fixedly installed on the top of the base plate 102. A crossbar 106 is movably sleeved on the outer surface of the two round rods 124. The crossbar 106 is slidably sleeved on the outer surface of the threaded rod 105. A groove 107 is opened at the bottom of the crossbar 106. An electric push rod 125 is fixedly installed at the bottom of the crossbar 106. A slider 108 is fixedly installed at one end of the electric push rod 125. The motor 103 is started by an external power source. The motor 103 drives the rotating rod 104 to rotate. At this time, the rotating rod 104 drives the threaded rod 105 to rotate. When the threaded rod 105 rotates, it can drive the horizontal bar 106 on its outer surface to slide on the outer surface of the two round rods 124. When sliding, it drives the moving block 111 at its bottom to move laterally. At this time, the moving block 111 is located on one side of the feeding plate 123, which can drive the moving block 111 to move vertically, thereby improving the conveying efficiency.

[0024] like Figures 1 to 8 As shown, in one embodiment, the electric push rod 115 is fixedly connected to the outer surface of the limiting rod 113. The top of the base plate 102 is connected to the threaded rod 118 via a bearing. The top of the threaded rod 118 is fixedly connected to the rotating rod 117. The top of the rotating rod 117 is fixedly mounted with a gear 116. When the slider 108 moves laterally, the rack 1101 moves laterally via the limiting telescopic bar 109. At this time, the rack 1101 moves on the outer surface of the gear 116, which can drive the meshing gear 116 to rotate. At this time, the rotation of the gear 116 drives the rotating rod 117 at its bottom to rotate. The rotating rod 117 drives the threaded rod 118 to rotate. At this time, the lifting bar 120 connected to the outer surface of the threaded rod 118 moves up and down under the limitation of the limiting telescopic bar 119.

[0025] As Figures 1 to 8 shown in one embodiment, one side of the slider 108 is fixedly installed with a limiting telescopic bar 109, one end of the limiting telescopic bar 109 is fixedly installed with a gear rack 1101, the gear rack 1101 is engagedly connected to the outer surface of a gear 116, one end of the gear rack 1101 is fixedly installed with a limiting telescopic rod two 126, the lifting bar 120 is movably sleeved on the outer surface of the threaded rod two 118 through a connecting bar, when the carton is conveyed above the conveying belt 101, in order to prevent the carton being conveyed from entering the bottom of the feeding plate 123 after the feeding plate 123 is lifted, causing the feeding plate 123 to be unable to move downward, at this time the lifting bar 120 blocks the carton moving on the upper surface of the conveying belt 101, when the moving block 111 moves towards the direction of the air cylinder 122, the lifting bar 120 moves upward, when the moving block 111 moves away from the vertical plate 121, the gear 116 reversely rotates, at this time the lifting bar 120 moves downward to block the carton, the forward rotation and reverse rotation of the gear 116 can make the threaded rod two 118 rotate at the same time, at this time the outer surface of the lifting bar 120 connected through the connecting bar moves upward or downward under the limiting of the limiting telescopic rod one 119, which can block the carton moving on the upper surface of the conveying belt 101.

[0026] Working principle: in use, the carton is conveyed to the direction of the vertical plate 121 by the conveying belt 101, at this time it enters the front of the lifting strip 120, and then enters the upper surface of the feeding plate 123. The cylinder 122 is started by an external power source at this time, the feeding plate 123 is driven by the cylinder 122 to move upward in the inside of the round rod 124, which can drive the carton to be lifted, facilitating clamping. At the same time, the motor 103 is started by an external power source, the rotating rod one 104 is driven by the motor 103 to rotate, at this time the rotating rod one 104 drives the threaded rod one 105 to rotate, when the threaded rod one 105 rotates, the horizontal strip 106 on the outer surface of the threaded rod one 105 can slide on the outer surface of the two round rods 124, and the horizontal strip 106 on the outer surface of the threaded rod one 105 can slide on the outer surface of the two round rods 124. When sliding, the moving block 111 at the bottom of the horizontal strip 106 moves horizontally, at this time the moving block 111 is located on one side of the feeding plate 123, the electric push rod three 125 is started by an external power source at this time, the sliding block 108 is driven by the electric push rod three 125 to slide horizontally in the sliding groove 107, and the sliding block 108 is driven by the electric push rod three 125 to slide horizontally in the sliding groove 107. After sliding, the moving block 111 is located above the feeding plate 123, the electric push rod one 110 is started to push the moving block 111 to move downward, at this time the electric push rod two 115 is started by an external power source to push the moving clamp block 114 to slide on the outer surface of the limiting rod 113, and the moving clamp block 114 is started by an external power source to push the moving clamp block 114 to slide on the outer surface of the limiting rod 113. After sliding, the moving clamp block 114 and the fixed clamp block 112 can clamp the carton, the sliding block 108 is pushed to move in the sliding groove 107 by the electric push rod three 125 at this time, which can clamp and convey the carton at the bottom to the other side of the conveying belt 101. At the same time, when the sliding block 108 moves horizontally, the rack 1101 is driven by the limiting telescopic strip 109 to move horizontally, at this time the rack 1101 moves on the outer surface of the gear 116, at this time the gear 116 is driven by the rack 1101 to rotate, at this time the gear 116 is driven by the rack 1101 to rotate. The rotating rod two 117 at the bottom of the gear 116 rotates, the rotating rod two 117 drives the threaded rod two 118 to rotate, at this time the lifting strip 120 connected with the outer surface of the threaded rod two 118 is limited by the limiting telescopic rod one 119 to rise and fall, when the carton is conveyed above the conveying belt 101, in order to prevent the carton being conveyed from entering the bottom of the feeding plate 123 after the feeding plate 123 is lifted, causing the feeding plate 123 to be unable to move downward, at this time the lifting strip 120 blocks the carton moving on the upper surface of the conveying belt 101. When the moving block 111 moves towards the cylinder 122, the lifting strip 120 moves upward, when the moving block 111 moves away from the vertical plate 121, the gear 116 reverses to rotate, at this time the lifting strip 120 moves downward to block the carton. The forward rotation and reverse rotation of the gear 116 can make the threaded rod two 118 rotate at the same time, at this time the lifting strip 120 connected with the outer surface of the threaded rod two 118 is limited by the limiting telescopic rod one 119 to rise or fall, which can block the carton moving on the upper surface of the conveying belt 101.
