DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present application are within the scope of protection of the present application.

[0031] Embodiment 1:

[0032] Please refer to the drawings Figure 1 - the drawings Figure 2 , a lithium battery roller pressing device of the present application, comprising a roller 1 and a roller changing mechanism 2, the roller changing mechanism 2 is arranged below the roller 1, and the roller changing mechanism 2 is used for replacing the roller 1; the roller changing mechanism 2 comprises at least one multi-stage jacking component 21 and a translation component 22.

[0033] The multi-stage jacking component 21 comprises a multi-stage oil cylinder and a one-way valve, the one-way valve is arranged in the multi-stage oil cylinder, the one-way valve is used for controlling the hydraulic oil to flow in only one direction, and the multi-stage oil cylinder is used for controlling the roller 1 to be lifted in stages along a first direction. The multi-stage oil cylinder uses an existing proportional valve to control the flow rate and pressure of the hydraulic oil. After calculation, when the oil cylinder is lifted, the multi-stage oil cylinder first lifts the middle stage under the same oil pressure, and the innermost first stage oil cylinder is calculated. After being lifted, the middle second stage oil cylinder begins to be lifted, and the third stage oil cylinder begins to be lifted after the second stage oil cylinder is completely lifted. When the oil cylinder is lowered, it is lowered in the order of three two one, thereby ensuring the stability of lifting. Moreover, the oil inlet and the oil outlet of the multi-stage oil cylinder are both realized by a one-way valve to realize a one-way oil path. When the oil inlet loses power, the oil inlet stops oiling, the one-way valve immediately reverses and locks, and the multi-stage oil cylinder immediately remains in the original state before losing power, which can prevent the piston from falling without control, thereby improving the safety of the operation of the multi-stage jacking component 21.

[0034] The translation component 22 includes slide rails 221 symmetrically arranged on both sides of the multi-stage jacking component 21, which are arranged along the second direction to cooperate with the translation of the roller 1. The slide rails 221 can be connected with the existing roller unloading vehicle 3, and the rollers of the roller unloading vehicle 3 are matched with the slide rails 221, so that the slide rails 221 cooperate with the roller unloading vehicle 3 to translate the roller 1 along the second direction through the rollers, thereby realizing the replacement operation of the roller 1.

[0035] For ease of understanding, the first direction is the X direction. The second direction is the Y direction.

[0036] In the lithium battery roller pressing device in this embodiment, the multi-stage jacking component 21 is used to lift the roller 1 along the first direction, and the translation component 22 is used to translate the roller 1 along the second direction, so that the overall roller replacement operation process is compact, without the need to use expensive gantry cranes or manual intervention wire rope hoists, thereby saving labor, improving the degree of automation of operation, and making the operation simple and convenient, safe and reliable. The scheme can simultaneously save time cost, labor cost and equipment cost, and the roller replacement and maintenance cost is relatively small.

[0037] In some embodiments, the multi-stage jacking component 21 is symmetrically provided with two. In this way, the jacking operation of the multi-stage jacking component 21 on the roller 1 is more stable and balanced, thereby ensuring the smoothness and safety of the roller replacement operation.

[0038] In some embodiments, the multi-stage jacking component 21 is provided with a position sensor 211 on one side. The position sensor 211 can use a rope displacement sensor to measure displacement by pulling a rope or cable, and is usually used to measure linear displacement. With the addition of the position sensor 211 under the premise of two multi-stage jacking components 21, the phenomenon of different step speeds of the left and right multi-stage oil cylinders can be effectively prevented. The position sensor 211 and the proportional valve are used to control the oil inlet and outlet speed in real time, so that the two multi-stage oil cylinders are lifted synchronously, thereby ensuring the synchronous lifting of the roller 1 and the stability of the lifting.

[0039] In some embodiments, the multi-stage jacking component 21 is provided with an explosion-proof valve. With this setting, if the oil pipe bursts, the multi-stage oil cylinder remains in its original state, preventing systemic hazards and greatly improving the safety factor of the roller 1 lifting.

[0040] Embodiment 2:

[0041] The difference between this embodiment and embodiment 1 is that, please refer to Figures 3-4The roll changing mechanism 2 of the embodiment further comprises a supporting component 23 connected with the multi-stage jacking component 21 and used for placing the roll 1. By arranging the supporting component 23, the roll 1 is in contact with the supporting component 23, the contact area of the roll 1 is increased, the stability of the roll 1 is improved, and the smoothness of the roll 1 is ensured.

[0042] In some embodiments, the supporting component 23 is provided with an arc groove 231 corresponding to the roll 1. By this arrangement, the arc groove 231 is matched with the shape of the roll 1, so that the roll 1 can be accommodated in the arc groove 231. During the lifting and lowering of the roll 1, the roll 1 can be limited in the arc groove 231 to avoid sliding due to shaking, improve the stability of the roll 1, and make the lifting and lowering operation safer.

[0043] In the embodiment, the supporting component 23 is in large-area contact with the roll 1 during the lifting and lowering of the roll 1, thereby improving the stability of the roll 1 during the lifting and lowering, and being suitable for different speeds of the multi-stage jacking component 21, with wide adaptability and high stability.

[0044] Embodiment 3:

[0045] The difference between the embodiment and the embodiment 2 is that, as shown in Figure 5 The roll changing mechanism 2 of the embodiment further comprises a limiting component 24 arranged at the periphery of the roll 1 and used for limiting the roll 1. By this way, the limiting component 24 limits the periphery of the roll 1 to prevent the roll 1 from sliding during the lifting and lowering, thereby ensuring the stability of the roll 1 and making the roll 1 lift and lower within a predetermined range.

[0046] In some embodiments, the limiting component 24 comprises a limiting frame 241 surrounding the roll 1. By this way, the limiting frame 241 is arranged to prevent the roll 1 from tilting forward and backward during the lifting and lowering, thereby ensuring the roll 1 to lift and lower stably within a predetermined range.

[0047] In some embodiments, the limiting component 24 further comprises a baffle group 242 connected with the limiting frame 241 and protruding from the limiting frame 241. Specifically, the baffle group 242 is provided with four baffle blocks 2421 for limiting the two ends of the roll 1. By this arrangement, the baffle group 242 limits the two ends of the roll 1 by the baffle blocks 2421, and by protruding from the limiting frame 241, the baffle group 242 can prevent the roll 1 from sliding left and right, ensure the roll 1 to lift and lower stably within a predetermined range, and effectively ensure the reliability and smoothness of the jacking.

[0048] The limiting parts 24 in the embodiment can limit the positions of the rolling mill roller 1 in front, back, left and right directions, effectively prevent the rolling mill roller 1 from tilting forward and backward or sliding left and right, and ensure the rolling mill roller 1 to lift within a predetermined range, greatly improve the stability of the rolling mill roller 1 lifting, and protect the safety and reliability of operation.
