[0001] The utility model relates to the technical field of twin-screw replacement, in particular to a twin-screw replacement trolley for lithium battery homogenization equipment. Background Art

[0002] The mainstream homogenization equipment in the lithium battery industry mainly includes three categories: twin planetary mixers, twin screw extruders, and circulating pulping equipment. Among them, the twin screw continuous pulping system has gradually increased its market share due to its high efficiency and low space occupation. Regarding the maintenance of twin screw equipment, the disassembly and assembly of the screw is the key point and difficulty.

[0003] In the prior art, after the screw is disassembled and assembled, its handling process is obviously inconvenient. For a small screw, the operator needs to manually carry it to the cart, which not only increases the work intensity, but also poses a potential safety risk. For a large screw, a crane must be used for transportation, which is cumbersome and time-consuming, seriously affecting work efficiency. Therefore, how to simplify the handling process of the screw, improve work efficiency, and ensure operational safety has become a problem that needs to be solved urgently. Utility Model Content

[0010] Preferably, a thread is provided inside the push plate, and the thread is engaged with the screw rod, and the push plate is slidably connected to the slide rod.

[0011] Preferably, a shock absorbing mechanism is provided on the bottom surface of the frame, and the shock absorbing mechanism includes a bottom block, the bottom block is fixedly mounted on the bottom surface of the frame, a mounting frame is rotatably connected to the inner side of the bottom block, a cylinder is fixedly mounted on one side of the mounting frame, a shock absorber is fixedly mounted on the other side of the mounting frame, a connecting rod is rotatably connected between the shock absorber and the bottom block, and the output end of the cylinder is rotatably connected to the scissor arm.

In addition, since the need for manual direct handling of the screw is reduced, especially when handling larger or heavier screws, the safety risks caused by improper handling are reduced. The lifting platform and the screw are pushed in a mechanized manner, which simplifies the operating steps, making the whole process easier and reducing the possibility of human error.

[0014] 2. In the case of shaking caused by uneven ground, the telescopic and unfolding force of the scissor arms of the utility model can drive the oil cylinder and the mounting frame to move, thereby activating the shock absorber. This design enhances the stability when transporting the screw on uneven ground, absorbs vibrations through the shock absorber, and effectively reduces the damage that the vibration may cause to the screw and the transporting equipment. This not only extends the service life of the equipment, but also ensures the safety of the screw during the transport process, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5 The utility model provides a technical solution: a double-screw replacement trolley for lithium battery homogenization equipment, including a frame 1, the bottom surface of the frame 1 is rotatably connected to a pulley 6 through a bearing, and these pulleys 6 are evenly distributed at the four corners of the bottom surface of the frame 1, ensuring the stability and flexibility of the trolley's movement. The pulley 6 can be fixed to the frame 1 by bolts or welding to ensure that it will not fall off during the movement. The top surface of the frame 1 is installed with a scissor arm 2, and the scissor arm 2 enables the lifting platform 3 to move up and down stably. The scissor arm 2 is connected to the frame 1 by a pin shaft, which can achieve flexible extension and contraction. The top of the scissor arm 2 supports the lifting platform 3, which provides convenience for the disassembly and assembly of the screw. Two sets of screw tooling 4 are fixedly installed on the top surface of the lifting platform 3, which are symmetrically distributed on the top surface of the lifting platform 3, and the screws can be conveniently placed and fixed. The screw tooling 4 can be fixed to the lifting platform 3 by bolts or welding to ensure its stability and load-bearing capacity.

[0026] See also Figure 1-5In order to facilitate the operator to push the trolley, a push handle 5 is fixedly installed on the top surface of the frame 1. In addition, a mounting plate 7 is fixedly installed on the top surface of the lifting platform 3, and a screw rod 8 is rotatably connected to the inner side of the mounting plate 7 through a bearing. The screw rod 8 and the slide rod 9, which are also installed on the inner side of the mounting plate 7, provide precise guidance for the movement of the push plate 10. The push plate 10 is sleeved on the screw rod 8 and the slide rod 9, and the thread opened inside it is meshed with the screw rod 8, so that the rotation of the screw rod 8 can drive the push plate 10 to slide along the slide rod 9. A large gear 11 is fixedly installed on one end of the screw rod 8, and a rotating shaft 12 is rotatably connected to the surface of the lifting platform 3 through a bearing. A turning handle 14 is fixedly installed on one end of the rotating shaft 12. The material of this turning handle 14 is selected from ferritic stainless steel, which is both strong and corrosion-resistant. A small gear 13 is also fixedly installed on the surface of the rotating shaft 12, and this small gear 13 is meshed with the large gear 11 to form a labor-saving lever mechanism.

[0027] Embodiment 2

[0028] See also Figure 4-5 The bottom surface of the frame 1 is provided with a shock absorbing mechanism, which includes a bottom block 15, which is fixedly mounted on the bottom surface of the frame 1 by welding or bolting. The inner side of the bottom block 15 is rotatably connected to the mounting frame 16 by a bearing or a pin, which allows the mounting frame 16 to rotate freely within a certain range to adapt to vibrations in different directions. An oil cylinder 17 is fixedly mounted on one side of the mounting frame 16 by bolts or welding, while a shock absorber 18 is fixedly mounted on the other side. The shock absorber 18 is usually a hydraulic or pneumatic shock absorber, which is filled with a special damping medium. When vibrated, these media can absorb vibration energy by compression and expansion. The shock absorber 18 is rotatably connected to the bottom block 15 by a connecting rod 19, which can be hinged or pinned to ensure that it can rotate flexibly during the vibration process, thereby effectively transmitting the shock absorbing force.

[0029] Working principle: The scissor arm 2 is pushed to retract by the oil cylinder 17. At this time, the scissor arm 2 retracts and lifts the lifting platform 3 upward until the lifting platform 3 is level with the height of the screw removal port. Then the screw is pulled out of the barrel and placed on the corresponding screw tooling 4. Then the lifting platform 3 is lowered to the bottom height to remove, clean or weigh and replace the external components of the screw. When installing the screw, the lifting platform 3 is raised to the level with the height of the screw removal port. Then the staff can turn the shaft 12 through the handle 14, and the shaft 12 can then drive the small gear 13 to rotate, and the small gear 13 then drives the large gear 11 meshing with it to rotate, and the small gear 13 and the large gear The wheel 11 can form a labor-saving lever, which reduces the physical consumption of the staff. The large gear 11 then drives the screw rod 8 to rotate. At this time, since the push plate 10 is provided with a thread, the screw rod 8 can drive the push plate 10 to move. The push plate 10 can then push the screw rod until the screw rod is pushed into the removal opening. At this time, the screw rod can be installed. The utility model drives the scissor arm 2 to contract to lift the platform 3 through the oil cylinder 17, so that the disassembly and assembly process of the screw rod is faster and more efficient. The lifting platform 3 can accurately align with the screw removal opening, reducing the time for adjusting the position, thereby improving work efficiency. The principle of the labor-saving lever is used to drive the large gear 11 through the small gear 13 The screw rod 8 and the push plate 10 rotate to drive the screw rod 8 and the push plate 10 to push the screw rod, which significantly reduces the physical exertion of the staff, makes the installation process of the screw rod easier, reduces the labor intensity of the operators, and reduces the need for manual direct handling of the screw rod, especially when handling larger or heavier screw rods, reduces the safety risks caused by improper handling. The lifting platform 3 and the pushing screw rod are mechanized to simplify the operation steps, making the whole process easier and reducing the possibility of human error. In the process of moving and transporting the screw rod, if it shakes due to the uneven ground, the force of the scissor arm 2 to expand and retract can drive the oil cylinder 17 moves, and the cylinder 17 then drives the mounting frame 16 to move. The mounting frame 16 can push the shock absorber 18 at this time. At this time, the vibration can be absorbed by the shock absorber 18, so as to reduce the vibration intensity. In the case of shaking caused by the uneven ground, the telescopic and unfolding force of the scissor arm 2 can drive the cylinder 17 and the mounting frame 16 to move, so as to activate the shock absorber 18. This design enhances the stability when carrying the screw on the uneven ground, absorbs the vibration by the shock absorber 18, and effectively reduces the damage that the vibration may cause to the screw and the handling equipment, which not only prolongs the service life of the equipment, but also ensures the safety of the screw during the handling process.
