[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0019] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0020] Combination Figure 1-4As shown, the stacking device includes a frame 1, a slide 2 that can slide laterally is provided on the frame 1, a slide seat 3 that can slide longitudinally is provided on the slide 2, a straight arm 4 is provided in the slide seat 3 for sliding downward, a connecting seat 5 is provided at the bottom of the straight arm 4, a rotating gear plate 6 is rotatably provided at the bottom of the connecting seat 5, a clamping seat 7 is connected to the bottom of the rotating gear plate 6, a pair of clamping claws are provided in the clamping seat 7, a driving gear 9 is rotatably provided in the connecting seat 5 and the driving gear 9 is meshed with the rotating gear plate 6, and a driving motor 10 for driving the driving gear 9 to rotate is also provided on the top of the connecting seat 5.

[0021] In the production of sauces, sauce cans are packed into sauce bags, which are then packed into boxes according to a certain quantity. Finally, the device can be used to stack the boxes in sequence for easy storage later.

[0022] In an embodiment, a conveyor platform is provided next to the frame and the front end of the conveyor platform is located inside the frame, and a pallet is placed inside the frame. The sealed packaging boxes are placed on the conveyor platform step by step and in an orderly manner, and the packaging boxes are moved toward the device one by one under the transportation of the conveyor platform. After the current packaging box is transported to the stacking position, the conveyor platform stops the transportation action. At this time, the clamp is located directly above the current packaging box, and the two clamps are in an open state. The straight arm moves downward until the packaging box is located in the two clamps, and then the two clamps clamp the packaging box, and then the clamp moves toward the pallet and stacks the packaging box on the pallet in an orderly manner as required. The conveyor platform and the pallet described in this embodiment are not the focus of the present device, so they are not specifically explained here.

[0023] During the stacking process of the packaging box, the two clamping jaws can rotate horizontally to adjust the stacking angle of the packaging box, making the device more adaptable. At the same time, the stacking effect of the packaging box can also be improved. When the two clamping jaws need to rotate horizontally, the driving motor drives the driving gear to rotate, the rotating gear plate also rotates, and the clamping seat at the bottom of the rotating gear plate rotates accordingly, thereby achieving the purpose of the two clamping jaws rotating horizontally at the same time.

[0024] As a preferred structure, Figure 4 As shown, the clamping claw comprises a clamping frame 81 slidably mounted in the clamping seat 7, a clamping plate 82 is provided downwardly on the outer side of the clamping frame, and a clamping cylinder 83 for driving the clamping frame to slide is also provided on the clamping seat 7.

[0025] When the current box needs to be clamped, the straight arm is located directly above the current box, and the straight arm moves downward until the box is located between the two clamping claws. Then the two clamping cylinders start to drive synchronously, and the two clamping plates slide inward respectively until the box is clamped. Finally, the two clamping claws are used to move the box to the corresponding position of the pallet and stack it in turn. In addition, the clamping distance between the two clamping plates can be controlled by the corresponding clamping cylinder, so it can be applied to the stacking of boxes of various specifications.

[0026] The bottom of the clamping plate is bent inwards, so that when clamping the packing box, the clamping plate can fit the packing box more closely, and the packing box can be clamped more firmly and stably.

[0027] In this structure, if Figure 1 In the figure, a pair of rotating wheels 11 are rotatably provided on both sides of the top of the frame 1, and a belt 12 is provided between the same pair of rotating wheels. Both ends of the slide 2 are connected to the corresponding belts 12 through connecting blocks 13, and a linkage shaft 14 is provided between the two rotating wheels 11 at one end. The frame 1 is also provided with a rotating motor 15 for driving the linkage shaft 14 to rotate.

[0028] In the embodiment, when the clamp needs to move laterally, the rotary motor starts to work, and the rotary motor drives the linkage shaft to rotate. The two rotating wheels at the corresponding end rotate, and under the linkage of the belt, the two pairs of rotating wheels rotate synchronously, and the slide moves laterally under the drive of the belt. Therefore, the clamp installed on the slide can move laterally.

[0029] In this structure, the slide 2 is provided with a longitudinal spur rack 16 , and the slide seat 3 is provided with a sliding motor 17 downward. The driving shaft of the sliding motor 7 is connected with a sliding gear 18 , and the sliding gear 18 is meshed and installed with the longitudinal spur rack 16 .

[0030] When the clamp needs to move longitudinally, the sliding motor starts to work, drives the sliding gear to rotate, and moves longitudinally along the length direction of the longitudinal spur rack. At this time, the slide seat moves longitudinally along the length direction of the slide under its action, thereby achieving the purpose of longitudinal movement of the clamp.

[0031] In addition, the side wall of the straight arm 4 is provided with vertical spur teeth 19 along the height direction, the slide seat 3 is provided with a lifting motor 20 facing inward, and the driving shaft of the lifting motor 20 is connected to a lifting gear 21, and the lifting gear 21 is meshed and installed with the vertical spur rack 19.

[0032] Finally, when the clamp needs to move vertically, the lifting motor starts to work, and the lifting motor drives the lifting gear to rotate. The straight arm slides vertically in the slide seat under the action of the vertical spur rack to drive the clamp to move up and down. Figure 3-4In the embodiment, a pulley 22 is provided on the side wall of the slide seat corresponding to the straight arm, so that the straight arm is more stable during the lifting process.

[0033] In addition, a limit frame 23 is provided on the slide seat, and the top of the limit frame 23 is bent toward the straight arm. In this structure, the top of the limit frame is the highest distance the straight arm rises. The limit frame can play a certain limiting role on the straight arm, further increasing the stability of the straight arm during the lifting process.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
