[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides a technical solution: a liftable palletizer, including a base plate 1 and a palletizer body 4, wherein an adjustment structure 2 is provided on the base plate 1, the palletizer body 4 is installed on the adjustment structure 2, and a fixing structure 3 is provided on the base plate 1. The adjusting structure 2 includes a sleeve 201, a lifting rod 202, a lifting plate 203, a bracket 204, a rotating shaft 205, a first gear 206, a fixed frame 207, a movable rack 208, an electric push rod 209, a movable plate 210, a second gear 211, a support frame 212, and a lifting rack 213. The sleeve 201 is mounted on the base plate 1, the lifting rod 202 is movably mounted inside the sleeve 201, the lifting plate 203 is mounted on the lifting rod 202, the bracket 204 is mounted on the base plate 1, the rotating shaft 205 is movably mounted on the bracket 204, the first gear 206 is mounted on the rotating shaft 205, and the fixed frame 207 is mounted on the base plate 1. On plate 1, the movable rack 208 is movably mounted on the fixed frame 207, the electric push rod 209 is mounted on the fixed frame 207, the movable plate 210 is mounted on the driving end of the electric push rod 209 and is connected to the movable rack 208, the second gear 211 is mounted on the rotating shaft 205, the support frame 212 is mounted on the base plate 1, the lifting rack 213 is movably mounted on the support frame 212 and is connected to the lifting plate 203, and several sleeves 201 and lifting rods 202 are provided. During the palletizing operation, in order to adapt to the needs of goods with different stacking heights, the height of the palletizer body 4 needs to be precisely adjusted. The electric push rod 209, as the core driving element, directly drives the movable plate 210 to generate axial displacement through its linear output. The movable plate 210 and the movable rack 208 are rigidly connected, driving the movable rack 208 to slide smoothly along the guide structure of the fixed frame 207. The moving rack 208 and the first gear 206 form a precision meshing pair, converting linear motion into circular motion of the rotating shaft 205, which is stably supported by the bracket 204. The second gear 211 rotates synchronously with the rotating shaft 205 and forms another meshing transmission with the lifting rack 213, converting the rotational motion back into the vertical motion of the lifting rack 213. The lifting rack 213, through a rigid connection, drives the lifting plate 203 to be precisely positioned vertically, while the lifting rod 202 guides the movement within the sleeve 201, ensuring a smooth and deviation-free lifting process. This transmission adopts a multi-stage motion conversion design, ensuring sufficient transmission accuracy and providing the necessary structural rigidity, enabling the palletizer to adapt to height adjustment requirements under different working conditions.

[0018] Furthermore, the lifting rod 202 is adapted to the sleeve 201, and the fixing frame 207 is provided with reinforcing ribs. The adapted lifting rod 202 moves stably within the sleeve 201, and the reinforcing ribs increase the stability of the fixing frame 207.

[0019] Furthermore, the electric push rod 209 is fixed to the fixed frame 207 by bolts, and the lifting rack 213 is adapted to the support frame 212. The electric push rod 209, which is fixed by bolts, is easy to install and remove on the fixed frame 207, and the adapted lifting rack 213 moves stably on the support frame 212.

[0020] Furthermore, the fixing structure 3 includes a placement frame 301, a moving block 302, a connecting frame 303, a rotating threaded rod 304, a first bevel gear 305, a rotating shaft 306, a second bevel gear 307, a mounting frame 308, a sliding block 309, a rotating threaded rod 310, a stabilizing frame 311, a rotating frame 312, an auxiliary wheel 313, a slot 314, a moving wheel 316, and an abutment plate 315. The placement frame 301 is mounted on the base plate 1, the moving block 302 is movably mounted on the placement frame 301, the connecting frame 303 is mounted on the placement frame 301, the rotating threaded rod 304 is movably mounted on the connecting frame 303 and is movably connected to the moving block 302, the first bevel gear 305 is mounted on the rotating threaded rod 304, the rotating shaft 306 is movably mounted on the placement frame 301, and the second bevel gear 307 is mounted on the rotating shaft 308. The second bevel gear 307 meshes with the first bevel gear 305. The mounting frame 308 is mounted on the placement frame 301. The sliding block 309 is movably mounted on the mounting frame 308. The rotating threaded rod 310 is movably mounted on the mounting frame 308 and is movably connected to the sliding block 309. The stabilizing frame 311 is mounted on the mounting frame 308. The rotating frame 312 is movably mounted on the mounting frame 308. The auxiliary wheel 313 is mounted on the rotating frame 312 and abuts against the sliding block 309. The slot 314 is provided on the moving block 302. The moving wheel 316 is mounted on the base plate 1. The abutment plate 315 is mounted on the moving block 302. When it is necessary to adjust the overall position of the palletizer, the operator can use the moving wheel 316 to flexibly move the device until it reaches the predetermined work position. At this time, the rotation of the drive shaft 306 causes the second bevel gear 307, which is linked to it, to rotate synchronously. This, in turn, drives the first bevel gear 305 to rotate the threaded rod 304 through the bevel gear pair transmission. The rotation of the threaded rod 304 causes the moving block 302 to make a precise linear displacement along the placement frame 301, and the abutment plate 315, which is fixed to it, moves accordingly until it forms a stable contact with the working surface. To further enhance the system rigidity, the threaded rod 310 can be adjusted synchronously, causing it to rotate within the mounting frame 308 and push the sliding block 309 to move. The auxiliary wheel 313 on the sliding block 309 rotates smoothly during the movement, causing the rotating frame 312 to produce a compound motion: one end extends away from the mounting frame 308 via the auxiliary wheel 313, while the other end retracts towards the mounting frame 308, ultimately causing the end of the rotating frame 312 to precisely engage with the slot 314 on the moving block 302. This linkage mechanism achieves complete locking of the moving block 302 through multiple mechanical constraints, ensuring that the contact plate 315 maintains constant contact pressure with the working surface, thus providing a solid foundation for stability in the palletizing operation.While ensuring ease of movement, it achieves absolute stability while in operation.

[0021] Furthermore, the placement rack 301 is adapted to the moving block 302, and the side wall of the abutment plate 315 away from the moving block 302 is provided with anti-slip texture. The adapted moving block 302 moves more stably within the placement rack 301. The anti-slip texture increases the friction when the abutment plate 315 contacts the placement plane, making the abutment plate 315 more stable when it is limited.

[0022] Furthermore, the connecting frame 303 is provided with reinforcing ribs, and several slots 314 are provided. The reinforcing ribs increase the stability of the connecting frame 303. Several slots 314 are equally spaced on the moving block 302. Several slots 314 facilitate the use of the rotating frame 312 to limit the position of the abutment plate 315 at different positions.

[0023] Furthermore, a rotating plate is provided on the rotating shaft 306, and a rotating handle is provided at the end of the rotating threaded rod 310 away from the sliding block 309. The rotating plate can easily drive the rotating shaft 306 to rotate, and the rotating handle can easily drive the rotating threaded rod 310 to rotate.

[0024] Working Principle: When the overall position of the palletizer needs to be adjusted, the operator can use the moving wheels 316 to flexibly move the device until it reaches the predetermined work position. At this time, the rotating shaft 306 is driven to rotate, causing the linked second bevel gear 307 to rotate synchronously. This, in turn, drives the first bevel gear 305 to rotate the threaded rod 304 through the bevel gear pair transmission. The rotation of the threaded rod 304 causes the moving block 302 to make precise linear displacement along the placement frame 301, and the fixed abutment plate 315 moves accordingly until it forms stable contact with the working surface. To further enhance the system rigidity, the threaded rod 310 can be adjusted synchronously, causing it to rotate within the mounting frame 308 and push the sliding block 309 to produce displacement. The auxiliary wheel 313 on the sliding block 309 rotates smoothly during movement, driving the rotating frame 312 to generate a compound motion: one end extends away from the mounting frame 308 via the auxiliary wheel 313, while the other end retracts towards the mounting frame 308, ultimately causing the end of the rotating frame 312 to precisely engage with the slot 314 on the moving block 302. This linkage mechanism achieves complete locking of the moving block 302 through multiple mechanical constraints, ensuring that the contact plate 315 maintains constant contact pressure with the working surface, thus providing a solid foundation for stability in palletizing operations. While ensuring convenient movement, it achieves absolute stability in the working state. During palletizing operations, to adapt to the needs of goods with different stacking heights, precise height adjustment of the palletizer body 4 is required. The electric push rod 209, as the core driving element, directly drives the moving plate 210 to generate axial displacement through its linear output. The moving plate 210 and the moving rack 208 are rigidly connected, driving the moving rack 208 to slide smoothly along the guide structure of the fixed frame 207. The moving rack 208 and the first gear 206 form a precision meshing pair, converting linear motion into circular motion of the rotating shaft 205, which is stably supported by the bracket 204. The second gear 211 rotates synchronously with the rotating shaft 205 and forms another meshing transmission with the lifting rack 213, converting the rotational motion back into the vertical motion of the lifting rack 213. The lifting rack 213, through a rigid connection, drives the lifting plate 203 to be precisely positioned vertically, while the lifting rod 202 guides the movement within the sleeve 201, ensuring a smooth and deviation-free lifting process. This transmission adopts a multi-stage motion conversion design, ensuring sufficient transmission accuracy and providing the necessary structural rigidity, enabling the palletizer to adapt to height adjustment requirements under different working conditions.
