Description

Technical Field

[0001] This utility model relates to the field of wine box production technology, specifically to a wine box production line anti-drop device. Background Technology

[0002] In the wine box production line, after the cardboard is pressed into a five-sided box, the box is conveyed to the next conveyor belt for further processing. Usually, a telescopic device is used to push the box away from the pressing area and onto the next conveyor belt. During this process, the box may roll and slide, causing the boxes to be arranged randomly on the conveyor belt. Some of them may even come into contact with the edge of the conveyor belt, resulting in the boxes frequently falling off the conveyor belt as it moves.

[0003] For example, on August 2, 2024, China published a patent publication number CN221458895U for a wine box production line anti-drop device, which is roughly described as follows: it includes a production base, a conveyor belt for transporting wine boxes is provided on the top of the production base, a storage groove is provided on the outside of the production base, a support block is provided inside the storage groove, a protective mechanism to prevent wine boxes from falling is provided on the top of the production base, the protective mechanism includes a protective plate, the protective plate is connected to the production base by a hinge, a groove is provided inside the support block, a support rod is provided inside the groove, and a first movable shaft is provided inside the support rod;

[0004] For example, on July 7, 2023, China published a patent publication number CN219312129U for an anti-fall device for a wine box production line. It is roughly described as including several legs and several vertical plates fixedly connected to the top of the legs. A conveyor belt mechanism is provided between the vertical plates and a fixed plate is fixedly connected between the vertical plates. A rotating rod is rotatably connected to the inner surface of the fixed plate. A first bevel gear is fixedly connected to the outer surface of the rotating rod. Several second bevel gears are meshed with the outer surface of the first bevel gear. This utility model relates to the field of wine box production technology.

[0005] While the aforementioned existing technical solutions can prevent wine boxes from falling off the conveyor belt and ensure that the conveyor belt's efficiency in transporting wine boxes is not affected, the aforementioned devices cannot limit the arrangement of wine boxes, or when they do limit the arrangement of wine boxes, the rotating plate is prone to causing the wine boxes to tip over, reducing work efficiency; and it is not convenient for the equipment to be precisely adjusted according to different specifications of wine boxes. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an anti-drop device for wine box production lines, which solves the problems mentioned in the background technology, such as the inability to limit the arrangement of wine boxes, or the tendency for the rotating plate to cause the wine boxes to tip over when the wine boxes are arranged and limited, thus reducing work efficiency; and the inconvenience of making the equipment accurately adjustable according to different specifications of wine boxes.

[0010] By adopting the above technical solution, according to the different specifications of the wine boxes, the third motor is started to drive the second bevel gear to rotate. The second bevel gear drives the first bevel gear and the double-sided threaded cylinder to rotate. The double-sided threaded cylinder drives the two threaded rods to move. The threaded rods drive the moving rod and the 7-shaped connector to move. The 7-shaped connector drives the limiting plate to move, so that the two limiting plates are suitable for wine boxes of different specifications. At this time, the first motor and the second motor are started at the same time. The first motor drives the first transmission roller to rotate. The first transmission roller drives the first conveyor belt to rotate, so that the equipment moves the wine box. The second motor drives the second transmission roller, and the second transmission roller drives the second conveyor belt to rotate. The second conveyor belt is used to reduce the friction between the wine box and the limiting plate, so as to reduce the probability of the wine box tipping over.

[0011] Optionally, a scale is fixedly connected to one end of the limiting plate near the 7-shaped connector, and a pointer that cooperates with the scale is provided at the top of the U-shaped frame.

[0012] By adopting the above technical solution, the scale and pointer work together to accurately observe the movement distance of the limit plate, thereby facilitating the adjustment of the limit plate and enabling the equipment to be precisely adjusted according to different specifications of wine boxes.

[0013] Optionally, each of the two movable rods has two cooperating limiting slide rods fixedly connected at one end close to each other, and the bottom end of the U-shaped frame has four limiting slide cylinders that are slidably connected to the limiting slide rods.

[0014] By adopting the above technical solution, the limiting slide bar and the limiting slide cylinder cooperate to limit the moving rod, thereby preventing the moving rod from shaking or deviating, and thus preventing the 7-shaped connector and the limiting plate from deviating, thereby improving the stability of the equipment.

[0015] Optionally, a support plate is fixedly connected to the inner sidewall of the U-shaped frame, and the top of the support plate is in close contact with the inner upper sidewall of the first conveyor belt.

[0016] By adopting the above technical solution, the support plate is used to support the first conveyor belt, thereby preventing the wine boxes from compressing and deforming the first conveyor belt, and preventing the first conveyor belt from shaking during operation, causing the wine boxes to sway and tip over, thereby improving the stability of the equipment.

[0017] Optionally, an arc-shaped guide is fixedly connected to one end of each of the two limiting plates.

[0018] By adopting the above technical solution, the arc-shaped guide is used to increase the feeding range between the two limiting plates, which facilitates the guidance of wine boxes that are located off-center and makes it easier to guide the wine boxes between the two limiting plates.
