[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0015] Example 1: See Figures 1 to 5 This utility model discloses an adjustable carton clamping device, including a mounting plate 01 for connection. The device is characterized in that: guide grooves 03 are connected to all four sides of the mounting plate 01 for guidance, and the guide grooves 03 are arranged in parallel. Mounting blocks 08 are slidably mounted on the guide grooves 03. A clamping plate is detachably mounted on the bottom of each mounting block 08. The mounting block 08 moves along the direction of the guide grooves 03, causing the clamping plate to move and thus clamping both sides of the carton. A pushing mechanism is also connected to the upper side of the mounting plate 01 to push the mounting block 08. The pushing mechanism drives the mounting block 08 to move, further driving the clamping plate to move and clamp. A hydraulic telescopic rod 20 is provided at the bottom of the mounting plate 01. The moving end of the hydraulic telescopic rod 20 is ball-jointed with a limiting plate 07 located between two clamping plates. The hydraulic telescopic rod 20 consists of two interlocking rods, a conventional mechanism. The hydraulic telescopic rod 20 pushes the limiting plate 07 to move, pushing the carton and assisting in the unloading of the carton.

[0016] In one embodiment, the pushing mechanism includes a hydraulic cylinder 09 disposed on the top of the mounting plate 01. Two piston rods 10 are symmetrically arranged inside the hydraulic cylinder 09, with one end of each piston rod 10 extending to the outside of the hydraulic cylinder 09 and connected to a pushing plate 02. In practice, an elastic component connects the two piston rods 10, and the elasticity of the elastic component assists in bringing the two piston rods 10 closer together. During the operation of the oil pumping device, liquid can enter the hydraulic cylinder 09 through the oil supply pipe 30. The entry of liquid increases the pressure inside the hydraulic cylinder 09, causing the two piston rods 10 to move away from each other, thereby pushing the pushing plates 02 on both sides to move. After the liquid is drawn by the oil pumping device, under the interaction of external air pressure and internal hydraulic pressure, the piston rod 10 retracts into the hydraulic cylinder 09. The opposing sides of the push plate 02 are connected to connecting columns 14. The top of the mounting plate 01 is slidably provided with a movable frame 12. The side of the connecting column 14 away from the push plate 02 is connected to the movable frame 12. The bottom of the movable frame 12 is connected to an adjusting sleeve 18. The movable end of the adjusting sleeve 18 is connected to a transverse rod 24 connected to the mounting block 08. During the movement of the push plate 02, the connecting column 14 is moved, thereby moving the movable frame 12, the adjusting sleeve 18 and the transverse rod 24, thus realizing the movement of the mounting block 08.

[0017] In one embodiment, the guide groove 03 is provided with multiple threaded holes, and the mounting plate 01 is provided with threaded grooves that mate with the threaded holes. The corresponding threaded holes and threaded grooves are threadedly connected by bolts for fixing the mounting plate 01 and the guide groove 03. The mounting plate 01 and the guide groove 03 are fixed relative to each other by the bolts in the threaded holes. After removing the bolts, the position of the guide groove 03 is adjusted, and then fixed by the bolts. The initial position of the guide groove 03 can be set, which facilitates the clamping of the carton.

[0018] In one embodiment, during clamping, the two piston rods 10 are pushed away by the oil pumping device, which in turn causes the push plate 02 to move the connecting column 14, the moving frame 12, the adjusting sleeve 18, and the transverse rod 24. This causes the two mounting blocks 08 and the clamping plate to move away from each other, and the moving end of the hydraulic telescopic rod 20 extends to prepare for clamping. When the clamping plate expands to a designated position, the oil pumping device draws liquid from the hydraulic cylinder 09, causing the push plate 02 to move the connecting column 14, the moving frame 12, the adjusting sleeve 18, and the transverse rod 24. This causes the two mounting blocks 08 and the clamping plate to move closer to each other, and the moving end of the hydraulic telescopic rod 20 retracts. At this time, the carton is clamped. When the carton is moved to a certain position, the two piston rods 10 move away again, and the carton is put down.

[0019] Example 2: like Figure 1 - Figure 5 As shown. The difference between this embodiment and Embodiment 1 lies in the oil pumping device; In this embodiment, the oil pumping device includes a circulation pump 23 fixedly connected to the mounting plate 01. One end of the circulation pump 23 is connected to a conduit 13, and the other end of the conduit 13 is connected to a temporary storage box 15 located on the upper side of the mounting plate 01. One end of the circulation pump 23 is connected to a supply pipe 29 connected to the oil supply pipe (30). After the circulation pump 23 is powered on, liquid flow can be realized. The two circulation pumps 23 on both sides realize the back-and-forth circulation of liquid in the whole device. Through the extraction of the circulation pump 23, the liquid enters the oil supply pipe 30 through the supply pipe 29, and further enters the mounting plate 09. Thus, the piston rod 10 is pushed to move through the hydraulic cylinder 09, realizing the unfolding of the mounting block 08. During the pumping of the circulation pump 23, the liquid enters the temporary storage box 15 through the oil supply pipe 30 and then through the conduit 13 to realize storage, thereby causing the two piston rods 10 to retract, thereby realizing clamping.

[0020] In the second embodiment, the hydraulic cylinder body 09 is provided with a guide hole 27 for guiding the piston rod 10 to move. A flow control valve is connected to the oil supply pipe (30), and a solenoid valve is connected to the supply pipe 29. The guide hole 27 ensures the movement space of the piston rod 10 and limits the movement direction of the piston rod 10. The flow control valve controls the instantaneous flow rate to avoid damage to the carton due to excessive speed. The solenoid valve controls the flow of liquid.

[0021] Example 3: like Figure 1 - Figure 5 As shown. The difference between this embodiment and Embodiment 1 lies in the different clamping plates; In this embodiment, the clamping plate includes a connecting strip 25 movably sleeved on the mounting block 08. A clamping plate 04 is fixedly connected to the bottom of the connecting strip 25. The clamping plate 04 is provided with multiple grooves, and multiple buffer blocks 06 are fixedly connected in the grooves. A horizontally arranged adjusting plate 26 is connected to the multiple buffer blocks 06 located in a straight line. The cross-section of the connecting strip 25 adopts a convex structure. Utilizing its basic shape, it can be connected to the mounting block 08, thereby connecting the mounting block 08 and the connecting strip 25. At the same time, the corresponding positions of the mounting block 08 and the connecting strip 25 are... Each component is equipped with a limiting hole, and a thread is provided inside the limiting hole. A fixing bolt is connected to the threaded limit hole to fix the mounting block 08 and the connecting strip 25 relative to each other, which ensures the stable connection between the mounting block 08 and the connecting strip 25. During the movement of the mounting block 08, the connecting strip 25 and the clamping plate 04 are moved, realizing the clamping and releasing of the carton. The buffer block 06 is made of polyurethane memory foam material, which can provide cushioning. The adjusting plate 26 is made of silicone-based material, which can provide a smaller adhesive force, increase friction, and reduce the clamping force during movement, thereby reducing damage to the carton.

[0022] The bottom of the clamping plate 04 is rotatably connected to an arc-shaped plate 05. A buffer sheet is pasted on the inner side of the arc-shaped plate 05. The bottom of the limiting plate 07 is connected to a rubber pad. The arc-shaped plate 05 adopts an arc-shaped structure, which can be inserted into the bottom of the carton in advance. Together with the clamping plate 04, it forms a larger clamping area on the carton, reducing local pressure and further reducing damage to the carton.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.

[0024] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
