Description

Technical Field

[0001] The present invention relates to the technical field of packaging box production equipment, and in particular to an automatic production device for chocolate packaging boxes. Background Art

[0002] Chocolate boxes are a key component of food packaging, designed specifically for protecting, displaying, and transporting chocolate products. They are primarily made of food-grade PET / PP plastic, which combines lightweight and high transparency, and are precision-injected into thin-walled structures of 0.5-1.2mm. Currently, automated production lines for chocolate boxes generally employ a combination of conveyor belt transport and robotic gripping. However, in order to grab more chocolate boxes at once, the robotic arm is pushed to one side at the end of the conveyor belt and piles up. This causes friction and collision between the boxes, leading to contact position shifts (such as tilting and misalignment). This is especially true for lightweight square plastic boxes, as traditional baffles make it difficult to constrain their sliding. Subsequent gripping by the robotic arm can easily lead to missed grabs or collisions due to positioning deviations. Summary of the Invention

[0005] Preferably, the driving assembly includes two fixed bars fixedly arranged at the opposite ends of the two mounting brackets before and after. Activity slots are formed on both sides of each fixed bar. Rack teeth are fixedly arranged at positions near the two side edges of the upper end of each fixed bar.

[0006] Preferably, a packing box placing rack is installed at the front side of the conveyor. A first robotic arm is installed at one side of the packing box placing rack. A second robotic arm is installed at the rear side of the injection molding machine. Four stacking trays are placed around the second robotic arm.

[0007] Preferably, the rear one of the two mounting brackets blocks the rear side of the packing box body conveyed on the conveyor, and the feeding port allows the packing box body to pass through.

[0011] Preferably, the cylinders are arranged obliquely. The two connecting shafts and the lower sides of the two connecting rods are rotatably connected respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The first robotic arm is used to evenly clamp the packaging box bodies placed on the packaging box placement rack, place them on the conveyor and transport them to the rear side, and then the second robotic arm transports the upper side to several groups of packaging box bodies close to the inner side of the component for clamping and placing them on the stacking tray for even stacking together to facilitate subsequent transportation. Through automation, the efficiency of the entire production line is improved. When several groups of packaging box bodies are conveyed to the position of the rear mounting rack, they are restricted to facilitate the subsequent packaging box bodies to be stacked and fitted together. The lower gear is then driven by the first motor to rotate, driving the meshing upper gear and the rotating rod to rotate, so that the two groups of movable sleeves connected by threads are brought closer to each other, driving the L-shaped plates and baffles on the two groups of round rods to move closer. When the flipping gears fixed on the two groups of round rods move, the meshing of the racks drives the round rods to flip over 180 degrees. After the sliding bottom flips to the movable groove and then fits with the plane on the fixed bar, it meets the continuous movement after flipping, clamps the two rows of packaging box bodies stacked on the conveyor, and pushes them to align with each other. After flipping, the L-shaped plates on both sides drive several groups of driving wheels to fit on the corresponding packaging box main body respectively, and the second motor drives the connected synchronous wheels to rotate, and drives the synchronous belt to drive another group of synchronous wheels and the transmission rod to rotate, so that several groups of driving wheels drive the fitted packaging box main body to rotate. When the approaching component drives the two groups of L-shaped plates and baffles away, the cavity distance between the two rows of packaging box main bodies is adjusted and driven directly outward for alignment, which is suitable for the second robotic arm to clamp the positions of the two rows of packaging box main bodies relative to each other, while avoiding tilting and misalignment of the packaging box main body. The activation of the two sets of cylinders can pull or push the two sets of connecting shafts and connecting rods to rotate along the first shaft seat, driving the transmission rod and several sets of driving wheels to adjust the height distance from the packaging box body to adapt to the sizes of different packaging box bodies. The two sets of racks drive the L-shaped plates and baffles on both sides to open and move away from the upper side of the packaging box body to avoid blocking the clamping work of the second robotic arm.

[0025] Working principle: Through the use of the first robotic arm 7 of the existing equipment, the packaging box main body 3 placed on the packaging box placement rack 6 is evenly clamped, placed on the conveyor 2 and transported to the rear side, and then the second robotic arm 8 transports the upper side to several groups of packaging box main bodies 3 close to the inner position of the component 4, clamped and placed on the stacking tray 9 for even stacking together, which is convenient for subsequent transportation. Through automation, the efficiency of the entire production line is improved; and when several groups of packaging box main bodies 3 are transported to the position of the rear mounting rack 41, they are restricted, which is convenient for the subsequent packaging box main bodies 3 to be stacked and fitted together. The first motor 48 drives the lower gear 49 to rotate, driving the meshing upper gear 410 and the rotating rod 45 to rotate, so that the two groups of movable sleeves 411 connected by thread are brought closer to each other, driving the L-shaped plates 54 and baffles 512 on the two groups of round rods 412 to move closer, and when the turning gears 413 fixed on the two groups of round rods 412 move, the meshing of the rack 53 drives the round rod 412 to turn over 180 degrees, and the sliding bottom 414 flips to the movable groove 52 and then fits with the upper surface of the fixed bar 51, so as to meet the continuous movement after turning over, and the two rows of packaging boxes accumulated on the conveyor 2 are mainly turned over. The packaging box bodies 3 are clamped together and pushed to align with each other; secondly, after turning over, the L-shaped plates 54 on both sides drive several groups of driving wheels 59 to fit on the corresponding packaging box bodies 3 respectively, and the second motor 55 drives the connected synchronous wheel 510 to rotate, and the driving synchronous belt 511 drives another group of synchronous wheels 510 and the transmission rod 58 to rotate, so that several groups of driving wheels 59 drive the fitted packaging box bodies 3 to rotate, and when the closing component 4 drives the two groups of L-shaped plates 54 and the baffle 512 away, the cavity distance between the two rows of packaging box bodies 3 is adjusted and the alignment is directly driven outward. It is suitable for the second robotic arm 8 to clamp the positions of two rows of packaging box bodies 3 relative to each other, while avoiding tilting and misalignment of the packaging box bodies 3.
