Description

Technical Field

[0001] This utility model relates to the field of food packaging box production technology, and in particular to a stacking device for food packaging box production. Background Technology

[0002] Food packaging boxes serve as crucial carriers for food storage, transportation, and sales, with a wide range of applications covering various food products, including snacks, fresh produce, and cooked foods. They are made from diverse materials, including paper, plastic, and metal, and vary in shape and size to meet the packaging needs of different foods. During the production process, finished food packaging boxes require stacking to facilitate subsequent storage, handling, and shipping.

[0003] However, current food packaging box stacking devices still have the following problems: 1. During the stacking process, improper operation can easily cause the packaging boxes to be squeezed and deformed, especially paper or thin plastic packaging boxes, which will affect subsequent use; 2. During the process of conveying the packaging boxes to the stacking area, the packaging boxes are prone to falling off the edge of the conveyor and causing damage. At the same time, the impact of falling during stacking may also cause wear on the corners of the packaging boxes, affecting product quality. Therefore, we have launched a stacking device for food packaging box production. Utility Model Content

[0004] The main objective of this invention is to provide a stacking device for food packaging box production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stacking device for food packaging box production includes a first support rod, a second support rod, and base feet. Two of each of the first and second support rods are provided. A fixing block is fixedly connected to the lower ends of both the first and second support rods. A conveyor belt is fixedly installed between the two first and two second support rods, and the conveyor belt is inclined at the upper left and lower right. Protective components are fixedly connected to the front and rear ends of the conveyor belt. Four base feet are provided, and a stacking assembly is fixedly connected to the upper ends of the four base feet. A fixing plate is fixedly connected to the upper right and lower right ends of the stacking assembly. A lifting device is inserted and installed at the lower end of the lower fixing plate.

[0006] Preferably, the lifting device includes a rotary motor, the output end of which is fixedly mounted with a threaded screw, the outer surface of which is threadedly connected to a transmission block, the left end of which is fixedly connected to a guide block, the left end of which is fixedly connected to a base plate, and springs fixedly connected to the four corners of the upper part of the base plate. The upper ends of the four springs are jointly fixedly connected to a stacking plate. The upper end of the rotary motor is fixedly connected to the lower end of the lower fixed plate, and the output end of the rotary motor passes through the lower end of the lower fixed plate and extends to the upper end of the lower fixed plate.

[0007] By adopting the above technical solution: the rotary motor drives the threaded screw to rotate, which in turn drives the transmission block and connected components to rise and fall, thereby realizing the automatic adjustment of the stacking plate height to adapt to different stacking volumes. The spring can buffer the impact of the packaging box falling and protect the packaging box from deformation.

[0008] Preferably, the protective assembly includes a mounting plate, a protective plate is fixedly connected to the upper front end of the rear mounting plate, a plurality of transmission rollers are movably mounted on the upper inner wall of the protective plate via a rotating shaft, and the front end of the rear mounting plate is fixedly connected to the rear end of the conveyor belt.

[0009] By adopting the above technical solution: the mounting plate provides stable support for the protective plate, the protective plate can prevent the packaging box from falling off the edge of the conveyor belt, and the drive roller can reduce the friction of the packaging box during transportation and avoid side wear.

[0010] Preferably, the drive rollers are distributed at equal intervals in pairs, and there are gaps between each roller and the conveyor belt.

[0011] By adopting the above technical solution, the equally spaced transmission rollers can uniformly guide the conveying direction of the packaging box. The gap between the rollers and the conveyor belt does not hinder the conveying process, and further reduces the risk of friction damage, ensuring smooth conveying.

[0012] Preferably, the stacking assembly includes a stacking box and a box cover. The stacking box has a stacking cavity at its upper and front ends. The middle of the right end of the stacking box has a through guide groove. The front of the left inner wall and the front of the right inner wall of the stacking cavity both have T-shaped slots. The left and right ends of the box cover are fixedly connected to T-shaped plates. The upper front end of the box cover has a through hand groove. The lower end of the stacking box is fixedly connected to the upper end of four feet.

[0013] By adopting the above technical solutions: the stacking cavity provides a regular stacking space for packaging boxes, the guide groove facilitates the movement of lifting device components, the T-shaped card slot and T-shaped card plate make it convenient to load and unload the box lid, and the hand slot facilitates operation, thereby improving the efficiency of picking and placing after stacking.

[0014] Preferably, the box cover is movably sleeved inside the stacking cavity, and the two T-shaped clamps are respectively movably clamped into the corresponding two T-shaped slots, with the stacking box located to the right of the conveyor belt.

[0015] By adopting the above technical solutions: the sleeve connection between the box cover and the stacking cavity and the snap-fit ​​connection between the T-shaped card plate and the card slot, the box cover is ensured to be installed firmly and easy to load and unload. The stacking box is located on the right side of the conveyor belt, ensuring that the packaging box falls accurately into the stacking cavity.

[0016] Preferably, the upper end of the threaded screw is movably connected to the lower end of the upper fixed plate via a rotating shaft, the guide block is movably sleeved in the guide groove, and the bottom plate and the stacking plate are both movably sleeved in the stacking cavity, and both have gaps with the inner wall surface of the stacking cavity.

[0017] By adopting the above technical solutions: the threaded screw is movably connected to the upper fixed plate to enhance stability; the guide block and guide groove cooperate to ensure the precise movement of the lifting components; the gap between the bottom plate and the stacking plate and the stacking cavity avoids friction and ensures smooth lifting.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, after the packaging box is conveyed to the right end by the conveyor belt, it falls into the stacking plate in the stacking cavity of the stacking assembly. The spring at the lower end of the stacking plate is compressed due to pressure, which plays a buffering role, reducing the impact when the packaging box falls and preventing corner deformation. As the packaging boxes are continuously stacked, the rotary motor in the lifting device is started. Its output end drives the threaded screw to rotate, causing the transmission block to drive the guide block to move down along the guide groove, thereby allowing the base plate, spring and stacking plate to move down synchronously, automatically making stacking space for subsequent packaging boxes. No manual adjustment is required, which improves stacking efficiency. When the appropriate number is stacked, the box cover is pulled by the hand groove, and the T-shaped card plate slides along the T-shaped card groove to remove the box cover, so that the stacked packaging box can be easily removed. The whole process is highly automated and can effectively protect the shape of the packaging box. 2. In this utility model, after the conveyor belt is started, the food packaging box is placed on it. The conveyor belt is set at an angle of left-up and right-down, which can naturally drive the packaging box to the right and down. During this process, the protective plate in the protective component can prevent the packaging box from falling from the front and rear ends of the conveyor belt. There is a gap between the transmission roller on the protective plate and the conveyor belt, which does not affect the transportation of the packaging box, and can reduce the friction between the packaging box and the protective plate, avoid the side wear of the packaging box, and ensure the integrity of the packaging box in the transportation process.
