[0040] Embodiment:

[0041] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the embodiment discloses a double-layer stacking device, which comprises a conveying belt 10, a lifting plate 20, a driving member 30 and a push-pull assembly 40. The conveying belt 10 is used for conveying plastic packaging bags 50, the push-pull assembly 40 is used for pulling the plastic packaging bags 50 back to the lifting plate 20 and pushing the plastic packaging bags 50 on the lifting plate 20 to the conveying belt 10, the driving member 30 is used for driving the lifting plate 20 to ascend and descend, and the push-pull assembly 40 is arranged on the lifting plate 20 and can ascend or descend with the lifting plate 20.

[0042] Specifically, the conveying belt 10 is provided with a plurality of baffle 11 groups, all the baffle 11 groups are arranged along the length direction of the conveying belt 10, each baffle 11 group comprises two baffles 11 arranged in parallel to each other, and there is a spacing between the two baffles 11, which forms a placing part, and a plurality of plastic packaging bags 50 arranged in order in a previous process step are placed in the placing part.

[0043] In the embodiment, each plastic packaging bag 50 is substantially in a plate structure, and after a plurality of plastic packaging bags 50 are arranged in order, the side surfaces of all the plastic packaging bags 50 are parallel to the plate surfaces of the baffles 11. In addition, the length direction of the baffle 11 is perpendicular to the length direction of the conveying belt 10.

[0044] The lifting plate 20 is arranged at the side of the conveying belt 10, and the bottom of the lifting plate 20 is provided with the driving member 30. Generally, the driving member 30 is a pneumatic cylinder, which directly drives the lifting plate 20 to reciprocate in the vertical direction.

[0045] The push-pull assembly 40 is movably arranged on the lifting plate 20, and the movement direction of the push-pull assembly 40 is perpendicular to the movement direction of the lifting plate 20.

[0046] In the working process, the plastic packaging bags 50 arranged in order are placed in the placing part of the baffle 11 group, and the conveying belt 10 moves intermittently. When the conveying belt 10 conveys the first group of plastic packaging bags 50 to the side of the lifting plate 20, the push-pull assembly 40 pulls the first group of plastic packaging bags 50 back to the lifting plate 20, and then the conveying belt 10 moves by a distance, so that the second group of plastic packaging bags 50 reaches the side of the lifting plate 20. At this time, the driving member 30 drives the lifting plate 20 to ascend, and under the action of the push-pull assembly 40, the first group of plastic packaging bags 50 is pushed to the upper side of the second group of plastic packaging bags 50.

[0047] Generally, the height of the baffle 11 is greater than or equal to twice the height of the plastic packaging bag 50, so that after the push-pull assembly 40 pushes the second group of plastic packaging bags 50 onto the first group of plastic packaging bags 50, the two groups of plastic packaging bags 50 can be stably and neatly overlapped in the placing part for subsequent process.

[0048] In one specific embodiment:

[0049] The push-pull assembly 40 includes a support frame 41, a first cylinder 42, a clamping plate 43, a support rod 44, a connecting rod 45, and an extension piece 46. The support frame 41 is in a U-shaped structure, and the two ends of the support frame 41 are fixedly arranged at the two ends of the lifting plate 20.

[0050] The cylinder body of the first cylinder 42 is fixedly arranged at the middle part of the support frame 41, so that the cylinder body of the first cylinder 42 is located above the lifting plate 20. The piston rod of the first cylinder 42 is arranged in a horizontal direction and perpendicular to the length direction of the conveying belt 10.

[0051] The clamping plate 43 has two, and two support rods 44 are arranged on each of the two clamping plates 43. The four support rods 44 at the top of the two clamping plates 43 are connected to the two ends of the two connecting rods 45.

[0052] The length direction of the clamping plate 43 is consistent with the length direction of the conveying belt 10, and the two clamping plates 43 have a certain spacing, which is greater than or equal to the length of the plastic packaging bag 50. In addition, one of the clamping plates 43 is close to the lifting plate 20, and the end of the piston rod of the first cylinder 42 is installed on the clamping plate 43 away from the lifting plate 20 and fixedly connected with the connecting rod 45 on the clamping plate 43.

[0053] In this embodiment, the push-pull assembly 40 is fixedly connected with the lifting plate 20 by arranging the support frame 41, and then the two clamping plates 43 are driven to reciprocate in the horizontal direction by the first cylinder 42.

[0054] In work, the lifting plate 20 is lifted by the driving member 30, so that the clamping plate 43 also moves in the vertical direction, thereby realizing the clamping of the plastic packaging bag 50 on the conveying belt 10 between the two clamping plates 43. When the two clamping plates 43 are driven by the first cylinder 42 to move towards the lifting plate 20, a group of plastic packaging bags 50 on the conveying belt 10 can be pulled back to the lifting plate 20.

[0055] When a group of plastic packaging bags 50 on the lifting plate 20 is pushed onto another group of plastic packaging bags 50, the driving member 30 drives the lifting plate 20 to rise to a certain height, which is generally equal to the height of the plastic packaging bag 50. Then the clamping plate 43 is driven by the first cylinder 42 to push the plastic packaging bag 50 on the lifting plate 20 to the top of the next group of plastic packaging bags 50 for overlapping.

[0056] Preferably, a telescopic part 46 is arranged at one end of the connecting rod 45, and the telescopic part 46 is used to adjust the distance between the two clamping plates 43, so that the baffle 11 can pass through the two clamping plates 43 after the two sets of plastic packaging bags 50 are overlapped.

[0057] The telescopic part 46 comprises a motor 461 and a screw rod 462. The motor 461 is fixedly arranged at one end of the connecting rod 45, and one end of the screw rod 462 is coaxially connected with an output shaft of the motor 461, and the length direction of the screw rod 462 is consistent with the length direction of the connecting rod 45.

[0058] A threaded hole is arranged at the top end of the support rod 44, and the threaded hole is matched with the screw rod 462. Thus, the screw rod 462 is driven to rotate by the motor 461, and then the distance between the two clamping plates 43 is adjusted. In the embodiment, the clamping plate 43 connected with the first cylinder 42 is connected with the motor 461, and a threaded hole is arranged at the top end of the support rod 44 of the other clamping plate 43.

[0059] In order to stabilize the movement of the two ends of the clamping plate 43, the connecting rod 45 is arranged at the two ends of the clamping plate 43, and the motor 461 and the screw rod 462 are symmetrically arranged.

[0060] In another specific embodiment,

[0061] The support frame 41 is parallelly arranged in two, and the first cylinder 42 is also arranged in two, and the cylinder bodies of the two first cylinders 42 are mounted on the two support frames 41. In addition, the support rod 44 is further provided with a balance rod 47, and the balance rod 47 is slidingly arranged on the support frame 41.

[0062] Through the embodiment, the stability of the overall structure can be improved.

[0063] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
