Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a pallet conveying device. Background Art

[0002] Palletizing pallets are used as bottom supports for bagged materials, minimizing the impact of uneven surfaces on the safety of the palletized materials. Palletizing pallets can also serve as lower supports for transferring bagged materials, facilitating the transfer of multiple bags. Currently, to improve transfer efficiency, pallets are placed in automatic pallet feeding devices, which then use automatic stacking devices to stack multiple bags on the pallet, and then a forklift is used to transport the bagged materials. However, when the automatic feeding devices currently used automatically push pallets, the upper pallet can interfere with the lower pallet, making it more difficult to push the pallet out. Utility Model Content

[0003] The utility model provides a stacking tray conveying device to solve the above-mentioned deficiencies in the prior art, solves the problem of poor tray pushing out, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A stacking pallet conveying device includes a base plate having a rectangular structure and a movable hole formed along its length. The base plate is mounted with a plurality of pillars and a concave shell. The lower end of the front wall of the concave shell has an ejection hole formed therein. An end plate is mounted at one end of the base plate. A thrust cylinder is mounted on the end plate. The movable end of the thrust cylinder is provided with a thrust plate. The thrust plate is provided with a guide block, which is movably mounted on the movable hole. The thrust cylinder can drive the thrust plate to move, thereby ejecting the pallet located at the bottom layer from the ejection hole. The concave shell can also limit the position of the pallet, thereby preventing the stacked pallets from falling during the pushing process.

[0006] Furthermore, a horizontal arm is provided at the lower end of the guide block, and vertical plates are respectively provided at the two ends of the horizontal arm, and a top wheel is rotatably provided at the upper end of the vertical plate, a vertical shaft is provided at the outer end of the horizontal arm, and an inner pressure wheel is rotatably provided at the upper end of the vertical shaft. A pair of vertical holes are respectively opened on both sides of the concave shell, and a movable rod is movably provided in the vertical hole, and a splint is provided at the inner end of the movable rod on the same side, and a spring is provided on the movable rod, and an inner push plate is provided at the outer end of the movable rod on the same side, and an upper top plate is provided on the movable rod, and the spring is located between the inner push plate and the upper top plate, and an inclined surface is formed on the lower wall of one end of the upper top plate, and the outer end of the inclined surface extends upward in an inclined manner, and the outer periphery of the top wheel is tangent to the lower wall of the upper top plate, and inclined walls are formed at both ends of the inner push plate, and the outer end of the inclined wall extends in an inclined manner inward, and the outer periphery of the inner pressure wheel is tangent to the outer wall of the inner push plate. When the top wheel is driven by the push cylinder to move, it can act on the lower wall of the upper top plate, and then use the outer structure of the upper top plate to move the upper top plate and the clamping plate upward. The movement of the clamping plate can drive the pallet to move upward for a distance to prevent the upper pallet from affecting the push of the lower pallet. The inner pressure wheel can act on the outer wall of the inner push plate, and then clamp the outer wall of the pallet through the clamping plate.

[0007] Furthermore, concave parts are respectively installed on both sides of the inner wall of the concave shell, and a plurality of sliding wheels are rotatably provided on the concave parts. Through the sliding wheels, the movement of the tray can be limited and guided during the pushing process.

[0008] Furthermore, the length of the inner pressure wheel is longer than the lifting distance of the movable rod. This arrangement ensures that the clamping stability can be ensured during the upward movement of the clamping plate.

[0009] The advantages of the above technical solution are:

[0010] The utility model ensures that the trays at the bottom layer are smoothly pushed out by clamping and moving the trays at the upper layer upwards. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 4 Shows a three-dimensional structure of one embodiment Figure 2 . DETAILED DESCRIPTION

[0016] like Figures 1 to 4 As shown, a pallet stacking conveyor device includes a rectangular base plate 1 with a movable hole along its length. Multiple pillars 10 are mounted on the base plate 1. A concave shell 2 is mounted on the base plate 1, and an ejection hole 20 is defined at the lower end of the front wall of the concave shell 2. Concave members 8 are mounted on both sides of the inner wall of the concave shell 2, and multiple sliding wheels are rotatably mounted on the concave member 8.

[0017] One end of the base plate 1 is mounted with an end plate 11, on which a thrust cylinder 3 is mounted. The movable end of the thrust cylinder 3 is provided with a thrust plate 30, which is provided with a guide block, which is movably mounted on a movable hole. A cross arm 31 is provided at the lower end of the guide block, and vertical plates 32 are provided at each end of the cross arm 31. A top wheel 33 is rotatably mounted on the upper end of the vertical plate 32. A vertical shaft 34 is provided at the outer end of the cross arm 31, and an inner pressure wheel 35 is rotatably mounted on the upper end of the vertical shaft 34. A pair of vertical holes 21 are respectively provided on both sides of the concave shell 2. A movable rod 6 is movably provided in the vertical holes 21. A clamping plate 36 is provided at the inner end of the movable rod 6 on the same side. A spring 37 is sleeved on the movable rod 6. An inner push plate 40 is provided at the outer end of the movable rod 6 on the same side. An upper top plate 38 is sleeved on the movable rod 6. The spring 37 is located between the inner push plate 40 and the upper top plate 38. A bevel 39 is formed on the lower wall of one end of the upper top plate 38. The outer end of the bevel 39 extends upward at an angle. The outer periphery of the top wheel 33 is tangent to the lower wall of the upper top plate 38. An inclined wall 41 is formed at both ends of the inner push plate 40. The outer end of the inclined wall 41 extends inward at an angle. The outer periphery of the inner pressure wheel 35 is tangent to the outer wall of the inner push plate 40. The length of the inner pressure wheel 35 is longer than the lifting distance of the movable rod 6.

[0018] In a specific application of this embodiment, the trays are stacked on the bottom plate 1 and in the concave shell 2 .

[0019] During the pushing process, the pushing oil cylinder 3 is started, and the pushing plate 30 is driven by the pushing oil cylinder 3 to move along the moving hole.

[0020] When the push plate 30 moves, it will drive the inner pressure wheel 35 and the top wheel 33 to move. When the inner pressure wheel 35 moves, it will act on the inner push plate 40, and make the inner pressure wheel 35 pass through the inclined surface 39 and move to the outer wall of the inner push plate 40. As the inner pressure wheel 35 moves, the inner push plate 40 and the clamping plate 36 connected thereto will move inward, thereby clamping the pallet through the clamping plate 36.

[0021] At the same time, when the top wheel 33 moves, it will act on the lower wall of the upper top plate 38 through the top wheel 33, thereby causing the upper top plate 38 to move upward, and in the process of moving upward, the upper top plate 38 will drive the pallet clamped by the clamping plate 36 to move upward, thereby causing the pallet on the upper layer to move upward, and then the pallet will be finally pushed out through the movement of the push plate 30.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
