Description

Technical Field

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

[0002] In logistics warehousing and goods transportation scenarios, large quantities of cardboard boxes are often stacked to save space. However, traditional cardboard box stacking methods have significant drawbacks: stacked boxes lack effective fixing structures and are prone to tipping over when subjected to external impacts or when stacked at high heights. This can not only damage the items inside the boxes and potentially cause safety accidents, but also increase the workload of staff in sorting and restabilizing, reducing work efficiency. Therefore, there is an urgent need for a device that can stably limit and fix stacked cardboard boxes and adapt to different stacking heights to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing device for stacking cardboard boxes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cardboard box stacking fixing device includes a base. The upper surface of the base has a sliding groove. Two symmetrically arranged sliders are slidably connected in the sliding groove. The upper ends of the two sliders are fixedly connected to limit plates. The upper ends of the two limit plates are each provided with a groove. Lifting plates are slidably connected in the two grooves. A moving mechanism for moving the two sliders is provided in the sliding groove. The moving mechanism includes a double-ended threaded rod rotatably connected between the inner walls of both ends of the sliding groove. The double-ended threaded rod passes through the two sliders and is threadedly connected to them. The rear walls of the two limit plates are each provided with a through groove.

[0005] Preferably, a motor is fixedly connected to the side wall of the base, and the end of the output shaft of the motor is fixedly connected to the end of the double-threaded rod.

[0006] Preferably, a U-shaped rod is slidably connected in both of the through slots, and the two ends of the U-shaped rod are respectively fixedly connected to the rear walls of the two lifting plates.

[0007] Preferably, a fixing block is fixedly connected to the upper end of each of the two limiting plates, an electric push rod is fixedly connected to the lower end of each of the two fixing blocks, and the telescopic ends of each of the two electric push rods are fixedly connected to the upper end of the U-shaped rod.

[0008] Preferably, the lower end of the base is provided with four casters, which are arranged in a rectangular pattern.

[0009] Compared with the prior art, the advantages of this utility model are as follows: 1. By setting up a moving mechanism, the motor drives the double-headed threaded rod to rotate, so that the two limit plates move closer or further apart synchronously. The position of the limit plates can be flexibly adjusted according to the actual size of the carton, so as to stably limit the carton laterally, effectively preventing the carton from tipping over. The operation is highly automated, requiring no manual adjustment, reducing the labor intensity of workers and improving work efficiency.

[0010] 2. By setting up a lifting plate, U-shaped rod and electric push rod, the height of the lifting plate can be easily adjusted, allowing the device to adapt to cartons of different stacking heights and effectively limit the upper part of the cartons. This solves the problem that traditional devices cannot fully limit high-stacked cartons due to their fixed height, further improving the limiting effect. Attached Figure Description

[0013] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] Reference Figure 1-6A cardboard box stacking fixing device includes a base 1. A groove 11 is provided on the upper end surface of the base 1. Two symmetrically arranged sliders 12 are slidably connected in the groove 11. Limiting plates 2 are fixedly connected to the upper ends of the two sliders 12. Grooves 4 are provided on the upper ends of the two limiting plates 2. Lifting plates 3 are slidably connected in the two grooves 4. A moving mechanism for moving the two sliders 12 is provided in the groove 11. The moving mechanism includes a double-ended threaded rod 13 rotatably connected between the inner walls of the two ends of the groove 11. The double-ended threaded rod 13 passes through the two sliders 12 and is threadedly connected to them. Through grooves 10 are provided on the rear walls of the two limiting plates 2.

[0015] Furthermore, to achieve automatic driving of the double-ended threaded rod 13 and reduce manual operation intensity, a motor 5 is fixedly connected to the side wall of the base 1, and the output shaft of the motor 5 is fixedly connected to the end of the double-ended threaded rod 13. The motor 5 can drive the double-ended threaded rod 13 to rotate stably, thereby providing power for the movement of the two sliders 12. Furthermore, to achieve synchronous lifting of the two lifting plates 3 and ensure the stability and consistency of the carton's positioning, a U-shaped rod 9 is slidably connected within both through slots 10. The two ends of the U-shaped rod 9 are fixedly connected to the rear walls of the two lifting plates 3. The U-shaped rod 9 connects the two lifting plates 3 into a single unit, ensuring that the two lifting plates 3 remain synchronized during lifting, thus avoiding uneven positioning of the carton due to asynchronous lifting. Furthermore, to facilitate convenient adjustment of the height of the lifting plate 3 to accommodate cartons of different stacking heights, a fixing block 6 is fixedly connected to the upper end of each of the two limiting plates 2, and an electric push rod 7 is fixedly connected to the lower end of each of the two fixing blocks 6. The telescopic ends of the two electric push rods 7 are fixedly connected to the upper end of the U-shaped rod 9. The electric push rod 7 can move the U-shaped rod 9 up and down by telescopic movement, thereby causing the lifting plate 3 to slide within the groove 4, thus achieving height adjustment of the lifting plate 3. Furthermore, to facilitate the movement of the device and improve its flexibility and practicality, four casters 8 are provided at the lower end of the base 1, arranged in a rectangular pattern. The rectangular arrangement of the casters 8 ensures the stability of the device during movement. At the same time, the casters 8 allow workers to easily move the device to the required work position without strenuous handling.

[0016] When using this utility model, the device is first moved to the designated position for carton stacking by the universal wheels 8 at the lower end of the base 1, and then the cartons to be stacked are neatly stacked on the upper surface of the base 1. When lateral restraint is required for stacked cartons, the motor 5 on the side wall of the base 1 is activated. The output shaft of the motor 5 drives the double-ended threaded rod 13, which is fixedly connected to it, to rotate within the slide groove 11. Since the double-ended threaded rod 13 is threadedly connected to two sliders 12, and the sliders 12 are slidably connected within the slide groove 11, the two sliders 12 move closer to each other along the slide groove 11 as the double-ended threaded rod 13 rotates. Simultaneously, the sliders 12 move, causing the limiting plates 2 fixedly connected to their upper ends to move synchronously towards the center until the inner walls of the two limiting plates 2 are in close contact with the sides of the stacked cartons. At this point, the motor 5 is turned off, and the cartons are stably laterally restrained by the two limiting plates 2, effectively preventing the cartons from tipping over in the lateral direction. When the stacked cartons are too tall and the top of the cartons needs to be limited, the electric push rod 7 connected to the lower end of the fixing block 6 at the upper end of the two limiting plates 2 is activated. The telescopic end of the electric push rod 7 will extend downward (or retract upward, depending on the actual needs), causing the U-shaped rod 9, which is fixedly connected to it, to slide up and down within the through groove 10 on the rear wall of the two limiting plates 2. As the U-shaped rod 9 slides, it will cause the lifting plate 3, which is fixedly connected to both ends, to move up and down synchronously within the groove 4 at the upper end of the limiting plate 2 until the height of the lifting plate 3 matches the stacking height of the cartons, effectively limiting the top of the cartons. At this time, the electric push rod 7 is turned off, and the lifting plate 3 will remain at the current height, working with the limiting plates 2 to achieve comprehensive limitation of cartons of different stacking heights, further improving the stability of the carton stacking. When it is necessary to adjust the position of the carton or move the device to other work areas, simply push the device, and the casters 8 at the bottom of the base 1 will roll, making the device easy to move and convenient to operate.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
