The anti-drop rod 8 is used to prevent the cans from piling up on the top of the lifting belt 3; the T-shaped rod 9, the T-shaped rod 9 is fixedly installed on the top of the anti-drop rod 8; the protective frame 10, the protective frame 10 is slidably installed on the circumferential surface of the T-shaped rod 9; the protective spring 11, the protective spring 11 is arranged between the T-shaped rod 9 and the protective frame 10, the protective spring 11 is used to prevent the deformation of the cans, and the protective frame 10 reciprocates to push away the cans piled on the top of the lifting belt 3, so that the cans can be evenly distributed on the lifting belt 3, thereby reducing the occurrence of excessive accumulation or tilting, and thus improving the transportation and lifting efficiency of the cans.

[0023] The screw rod 6 passes through the front right side of the lifting frame 1, the bottom of the protective frame 10 is set as an inclined surface, the bottom of the anti-drop rod 8 is set as an inclined surface, and the movement of the T-shaped rod 9 drives the protective frame 10 to move towards the direction close to the loading frame 131.

[0024] A linkage rod 12 is slidably installed on the front side of the lifting frame 1, and a No. 1 spring is arranged between the linkage rod 12 and the lifting frame 1. The anti-drop rod 8 contacts the linkage rod 12, and the protective frame 10 moves upward under the reaction force of squeezing the cans. By moving the protective frame 10 upward, it can be avoided that excessive thrust directly acts on the can body when pushing away the accumulated cans, thereby reducing the risk of deformation or damage of the cans.

[0025] When this embodiment is working: after placing the cans on the top of the lifting belt 3, the driving device 2 operates to drive the lifting belt 3 to move, and the lifting belt 3 moves to transport and lift the cans on the top of itself.

[0026] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a control component for controlling the feeding speed of cans is arranged on the top of the lifting frame 1, and an anti-rebound component is arranged on the front side of the lifting frame 1. The control component includes a feeding frame 131, a control groove 132, a control board 133, an L-shaped rod 134, a load-bearing rod 135 and a stabilizing ring 138. The feeding frame 131 is fixedly installed on the top of the lifting frame 1, and the control board 133 slides through the inner and outer walls of the feeding frame 131. The control groove 132 is opened on the right side of the control board 133, the L-shaped rod 134 is fixedly installed on the inner wall of the control groove 132, the load-bearing rod 135 is fixedly installed on the left side of the L-shaped rod 134, and the stabilizing ring 138 is fixedly installed on the circumferential surface of the load-bearing rod 135. By reasonably controlling the feeding speed, the damage of the cans during the lifting process can be effectively prevented, and controlling the feeding speed can make the lifting belt 3 run more smoothly, thereby further improving the transportation efficiency of the cans.

[0027] A load-bearing spring 136 is arranged between the stabilizing ring 138 and the feeding frame 131, and a load-bearing block 137 is fixedly installed on the circumferential surface of the load-bearing rod 135. The load-bearing block 137 moves to the right to reset and hit the feeding frame 131 to generate vibration. The load-bearing block 137 contacts the feeding frame 131, and the load-bearing block 137 moves to the right to reset and hit the feeding frame 131 to generate vibration, thereby preventing the cans from getting stuck inside the feeding frame 131, thereby avoiding uneven or unstable feeding due to the accumulation of cans or overly close arrangement.

[0028] The inner wall of the loading frame 131 is set as an inclined surface, the left side of the control board 133 is set as an inclined surface, the stabilizing ring 138 contacts the inner wall of the loading frame 131, and the L-shaped rod 134 moves to the left to drive the control board 133 to move.

[0029] The anti-rebound component includes a protection rod 141, a rack 142, a rotating rod 143, a protection plate 144, a protection ring 145 and a gear 147. The protection rod 141 is fixedly installed on the front side of the lifting frame 1, the rack 142 is slidably installed on the circumferential surface of the protection rod 141, the rotating rod 143 rotates and passes through the front and rear walls of the lifting frame 1, the protection plate 144 is fixedly installed on the circumferential surface of the rotating rod 143, the protection ring 145 is fixedly installed on the circumferential surface of the protection rod 141, and the gear 147 is fixedly installed on the circumferential surface of the protection rod 141.

By timely pushing off the adhered cans, the downtime can be reduced and the transportation rate can be helped to be increased.

[0031] When the present embodiment is working, the anti-drop rod 8 moves toward the direction close to the feeding frame 131, contacts the linkage rod 12 and squeezes the linkage rod 12. The linkage rod 12 is squeezed by the anti-drop rod 8 and moves toward the direction close to the rack 142. The linkage rod 12 moves toward the direction close to the rack 142 and squeezes the No. 1 spring. The No. 1 spring is squeezed by the linkage rod 12 and deforms and accumulates force. At the same time, the linkage rod 12 moves toward the direction close to the rack 142, contacts the L-shaped rod 134 and squeezes the L-shaped rod 134. The L-shaped rod 134 is squeezed by the linkage rod 12 and moves to the left. The L-shaped rod 134 moves to the left and drives the control plate 133 to move.

The stabilizing ring 138 moves to squeeze the load-bearing spring 136. The load-bearing spring 136 is squeezed by the stabilizing ring 138 to produce deformation and accumulate force. When the screw rod 6 rotates in the opposite direction to drive the anti-drop rod 8 to move away from the loading frame 131, the anti-drop The rod 8 moves in the direction away from the feeding frame 131 and is out of contact with the linkage rod 12. After the linkage rod 12 is out of contact with the anti-drop rod 8, the linkage rod 12 moves to the right side and resets under the elastic force of the No. 1 spring. The linkage rod 12 moves to the right side and resets to be out of contact with the L-shaped rod 134. After the L-shaped rod 134 is out of contact with the linkage rod 12, the stabilizing ring 138 moves to the right side and resets under the elastic force of the load-bearing spring 136. The stabilizing ring 138 moves to the right side and resets, driving the load-bearing rod 135 to move and reset. The load-bearing rod 135 moves and resets, driving the L-shaped rod 134 to move and reset. The L-shaped rod 134 moves and resets, driving the control board 133 to move to the right and reset. The control board 133 moves back and forth to divide the space inside the loading frame 131, thereby achieving the effect of controlling the feeding speed of the cans. At the same time, the load-bearing rod 135 moves and resets, driving the load-bearing block 137 to move to the right and reset. The load-bearing block 137 moves and resets to the right and hits the loading frame 131 to generate vibration, thereby preventing the cans from getting stuck inside the loading frame 131.

[0032] The load-bearing rod 135 moves to the left and contacts the inclined surface of the rack 142 and squeezes the rack 142. The rack 142 moves downward due to the squeezing of the load-bearing rod 135. The rack 142 moves downward to pull the protective spring 146. The protective spring 146 is pulled by the rack 142 to deform and accumulate force. At the same time, the rack 142 moves downward to squeeze the gear 147. The gear 147 is squeezed by the rack 142 and rotates. The rotation of the gear 147 drives the rotating rod 143 to rotate. The rotation of the rotating rod 143 drives the protective plate 144 to rotate. The protective plate 144 rotates to block the cans on the top of the lifting belt 3, thereby preventing the cans from hitting the lifting belt 3 and rebounding when unloading. At the same time, the protective plate 144 rotates and contacts the lifting belt 3 to push down the cans adhered to the surface of the lifting belt 3.
