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

[0003] The main purpose of the present invention is to provide an automatic production device for chocolate packaging boxes, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

Two groups of movable sleeves are movably provided on the outside of the two groups of rotating rods, and two groups of round rods are rotatably provided on the inside of the two groups of movable sleeves corresponding to the front and rear of the two groups of mounting frames. Flip gears are fixedly provided on the outer sides of the two groups of round rods near the movable sleeves, and a sliding bottom is fixedly provided on the upper side of the flip gear.

[0006] The two wheels are fixedly mounted on the front and rear ends of the two mounting brackets, and the two wheels are connected with each other via a plurality of guide wheels, each of which is connected to the front of the two mounting brackets.

[0007] Preferably, a packaging box placement rack is installed on the front side of the conveyor, a first robotic arm is installed on one side of the packaging box placement rack, a second robotic arm is installed on the rear side of the injection molding machine, and four groups of stacking trays are placed around the second robotic arm.

[0008] Preferably, the rear side group of the two groups of mounting frames blocks the rear side of the packaging box body being transported on the conveyor, and the feed port allows the packaging box body to pass through.

[0009] Preferably, the two sections of the threaded portion are arranged oppositely, the two sections of the threaded portion are threadedly connected to the two groups of movable sleeves on the rear side, the lower gear and the upper gear are meshed, and the round rod passes through the inner side of the movable opening.

[0010] Preferably, the movable groove satisfies the movement when the sliding bottom rotates, the rack and the flip gear are meshed, the first shaft seat corresponds to the position of the opening, and the connecting rod is tilted.

[0011] Preferably, several groups of driving wheels correspond to several groups of opening positions respectively, the synchronous wheels and the two groups of connecting rods are arranged on the same axis, and the synchronous belt passes through the inner side of the middle opening.

[0012] Preferably, the cylinder is arranged obliquely, and the two groups of connecting shafts are rotationally connected to the lower sides of the two groups of connecting rods.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

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.
