Abstract
Description
Technical Field
[0001] This utility model relates to the field of palletizing fixtures, specifically an adjustable packaging box palletizing fixture. Background Technology
[0002] In the modern logistics and warehousing industry, palletizing is a crucial step in the storage and transfer of goods. Palletizing fixtures, as the core components for this operation, directly impact palletizing efficiency and cargo safety. Currently, most palletizing fixtures on the market are fixed structures, exhibiting the following significant drawbacks: First, the clamping size and angle are not adjustable, only suitable for single-sized boxes. When dealing with boxes of different heights, widths, or shapes, different models of fixtures must be replaced, increasing equipment procurement costs, frequently interrupting the workflow, and reducing production efficiency. Second, clamping stability is insufficient; most fixtures only secure the box through a single clamping point or surface, making them prone to shifting, tipping, or even damaging the goods during handling. Utility Model Content
[0003] The purpose of this invention is to provide an adjustable packaging box palletizing fixture to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An adjustable packaging box palletizing fixture includes a top plate, an upper frame fixedly connected to the bottom of the top plate, docking seats fixedly connected to the left and right sides of the lower surface of the upper frame, an adjusting plate fixedly connected between two sets of docking seats, a fixing plate fixedly connected to the upper surface of the adjusting plate, bearing seats fixedly connected to the left and right sides of the upper surface of the fixing plate, a vertical plate fixedly connected to the side of the lower surface of the adjusting plate, a rotating shaft rotatably connected to the lower part of the outer wall of the vertical plate, a shaft mounting plate rotatably connected to the outer wall of the rotating shaft, a hinge plate fixedly connected to the lower surface of the shaft mounting plate, and an outer crossbar fixedly connected to the bottom of the hinge plate.

[0009] As a further improvement of this utility model: a push rod is installed at the bottom of the fixing plate, and a pressure plate is installed at the pushing end of the push rod.
[0010] As a further improvement of this utility model, a ball is installed at the front end of the threaded spring rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model uses an electric actuator to drive the telescopic rod to extend and retract, which in turn causes the shaft mounting plate to rotate around the pivot, thereby adjusting the tilt angle between the outer and inner crossbars. In conjunction with the detachable connection between the adjustment plate and the docking seat, it can achieve multi-dimensional adjustment of the clamping width, height, and angle.
[0013] This utility model uses hooks on the outer crossbar to hold the bottom of the packaging box on the outside, while the inner crossbar provides support from the inside.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-3 In this embodiment of the utility model, an adjustable packaging box palletizing fixture includes a top plate 1, which serves as the top connecting component of the fixture and is used to be fixedly connected to the execution end of handling equipment such as forklifts and robotic arms. The bottom of the top plate 1 is fixedly connected to an upper frame 2 by welding or bolts. The upper frame 2 is a rectangular frame structure that serves to support and connect various components.
[0020] The lower surface of the upper frame 2 is fixedly connected to the left and right sides by welding with docking seats 18. The two sets of docking seats 18 are fixedly connected to the adjusting plate 15 by bolts. The adjusting plate 15 is a horizontally set metal plate, and its length can be adapted according to actual needs. The detachable connection between the docking seats 18 and the upper frame 2 facilitates the replacement and maintenance of the adjusting plate 15.
[0021] A fixing plate 3 is fixedly connected to the upper surface of the adjusting plate 15 by bolts. The fixing plate 3 is set perpendicular to the adjusting plate 15, and its height is adapted to the height of the upper frame 2. Bearing seats 4 are fixedly connected to the left and right sides of the upper surface of the fixing plate 3 by bolts. Bearings can be installed in the bearing seats 4 to slide with the shaft in the upper docking seat 18 to adjust the distance between the two sets of adjusting plates 15.
[0022] A vertical plate 22 is fixedly connected to the lower side of the adjusting plate 15 by welding. The vertical plate 22 extends downward perpendicularly to the adjusting plate 15. A rotating shaft 8 is rotatably connected to the lower part of the outer wall of the vertical plate 22 by bearing. The rotating shaft 8 is horizontally set, and its axis is parallel to the length direction of the adjusting plate 15. A shaft mounting plate 11 is rotatably connected to the outer wall of the rotating shaft 8 by bearing. The shaft mounting plate 11 is an L-shaped metal plate that can rotate freely around the rotating shaft 8. A hinge plate 7 is fixedly connected to the lower surface of the shaft mounting plate 11 by welding. The hinge plate 7 extends downward perpendicularly to the shaft mounting plate 11. An outer crossbar 13 is fixedly connected to the bottom of the hinge plate 7 by bolts. The outer crossbar 13 is a cylindrical or rectangular metal rod used to support and clamp the outer side of the packaging box.
[0023] The lower part of the outer crossbar 13 is fixedly connected to a hook 21 by a nut. The hook 21 has an L-shaped structure and there are at least two sets of hooks, which are symmetrically distributed on both sides of the outer crossbar 13. The inner wall of the hook 21 can be glued with a rubber cushioning pad. When clamping the packaging box, the hook 21 can hook the bottom edge of the packaging box to prevent the packaging box from falling off during transportation. At the same time, the rubber cushioning pad can avoid rigid contact that could damage the packaging box.
[0024] The outer wall of the rotating shaft 8 is also rotatably connected to a curved part 12 via a bearing. The curved part 12 is an arc-shaped metal part with its bending direction facing the inside of the clamp. The bottom of the curved part 12 is fixedly connected to an inner crossbar 14 by welding. The inner crossbar 14 is arranged parallel to the outer crossbar 13 and is located inside the outer crossbar 13 to improve clamping stability. The outer wall of the rotating shaft 8 is equipped with a hook, and a ball 20 is provided at the lower part of the hook. The ball 20 is made of rubber and can play a buffering role when the rotating shaft hook comes into contact with other parts to avoid rigid collisions between parts.
[0025] The top of the shaft mounting plate 11 is hinged to a hinge joint 10 via a pin. The hinge joint 10 can rotate freely around the pin. The end of the hinge joint 10 away from the shaft mounting plate 11 is hinged to a telescopic rod 6 via a pin. The telescopic rod 6 is a telescopic metal rod, and its telescopic length can be controlled by a built-in hydraulic or electric structure. An electric actuator 9 is installed at the end of the telescopic rod 6 away from the hinge joint 10. The output end of the electric actuator 9 is fixedly connected to the telescopic rod 6. The telescopic rod 6 is moved by the telescopic drive of the electric actuator 9.
[0026] An inclined plate 5 is fixedly connected to the front end of the outer wall of the electric actuator 9 by welding. The inclined plate 5 is set at an angle, and a threaded spring rod 19 is installed at the bottom of the inclined plate 5. The threaded spring rod 19 includes an outer tube, an inner rod, and a spring. The inner rod can slide inside the outer tube, and the spring is sleeved on the outside of the inner rod. The elastic deformation of the spring realizes the buffering function. A ball 20 is installed at the front end of the threaded spring rod 19. The ball 20 is made of rubber. When the clamp holds the packaging box, the threaded spring rod 19 and the ball 20 can fit against the outer wall of the packaging box, playing a role in buffering and auxiliary positioning, and further improving the clamping stability.
[0027] A push rod 17 is installed at the bottom of the fixed plate 3. The push rod 17 is a hydraulic push rod or an electric push rod. Its pushing direction is perpendicular to the downward direction of the adjusting plate 15. The pushing end of the push rod 17 is fixedly connected to the pressure plate 16 by bolts. The pressure plate 16 is a rectangular metal plate with a silicone anti-slip pad pasted on its lower surface. When the clamp holds the packaging box, the push rod 17 can drive the pressure plate 16 to move downward and press the pressure plate 16 tightly against the top of the packaging box to form a "fixed at the top and bottom" clamping structure, which effectively prevents the packaging box from moving up and down during transportation.
[0028] According to the size of the packaging box to be stacked, the electric push rod 9 is started through the PLC control system. The electric push rod 9 drives the telescopic rod 6 to extend and retract, which drives the shaft mounting plate 11 to rotate around the rotating shaft 8, thereby adjusting the tilt angle of the outer crossbar 13 and the inner crossbar 14, so that the hook 21 of the outer crossbar 13 can correspond to the bottom edge of the packaging box, and the inner crossbar 14 can fit against the inner side wall of the packaging box.
[0029] The robotic arm moves the clamp above the packaging box and slowly lowers the clamp so that the outer crossbar 13 is located on the outside of the packaging box and the inner crossbar 14 is inserted into the inside of the packaging box. At this time, the hook 21 hooks the bottom edge of the packaging box.
[0030] Then, push rod 17 is activated, which drives pressure plate 16 to move downward until pressure plate 16 presses against the top of the packaging box, completing the double fixation inside and outside as well as top and bottom;
[0031] The robotic arm moves the clamped packaging box to the stacking position. After adjusting the position, it first controls the push rod 17 to retract, so that the pressure plate 16 is removed from the top of the packaging box. Then, it controls the electric push rod 9 to drive the telescopic rod 6 to retract, so that the outer crossbar 13 and the inner crossbar 14 are moved away from the packaging box. Finally, the robotic arm drives the clamp to rise, completing one stacking operation.
[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
