[0027] In order to further understand the application content, characteristics and effects of the present application, the following examples are given, and the detailed description is as follows with reference to the accompanying drawings.
[0028] Referring to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of an integrated transferable material conveying device in an embodiment, Figure 2 is another structural schematic view of an integrated transferable material conveying device in an embodiment, which includes a rack 1, a transfer mechanism 2, a buffer mechanism 3 and a material conveying mechanism 4. The rack 1 includes a rack body 11 and a moving part 12, and the moving part 12 is arranged at the bottom of the rack body 11. The transfer mechanism 2 includes a transfer tank body 21 and a first stirring part 22, the transfer tank body 21 is arranged in the rack body 11, and the first stirring part 22 is arranged in the transfer tank body 21. The buffer mechanism 3 includes a buffer tank body 31 and a second stirring part 32, the buffer tank body 31 is arranged in the rack body 11 and communicates with the transfer tank body 21, and the second stirring part 32 is arranged in the buffer tank body 31. The material conveying mechanism 4 communicates with the buffer tank body 31.
[0029] The integrated transferable material conveying device in the embodiment is applied to a lithium battery pole piece coating machine. The mixed slurry is conveyed to the transfer tank body 21 through a pipeline for transfer, and is subjected to preliminary stirring in the transfer tank body 21 by the first stirring member 22 to prevent the slurry from precipitating. Then, the slurry is conveyed into the buffer tank body 31 for buffering, so that the subsequent material conveying mechanism 4 can convey the slurry to the coating head of the coating mechanism for coating operation. The buffering of the slurry in the buffer tank body 31 ensures that the material conveying mechanism 4 can stably supply the coating mechanism, thereby maintaining the continuous operation of the coating mechanism. The transfer tank body 21 and the buffer tank body 31 are arranged on the frame body 11. Compared with the conventional mode of separately arranging the transfer tank body 21 and the buffer tank body 31 on the ground of a factory building, the embodiment improves the integration degree between mechanisms, and facilitates the position movement of the frame body 1 and the transfer tank body 21 and the buffer tank body 31 arranged thereon by the arrangement of the moving members 12, thereby improving the flexibility of the mechanism. In particular, when the transfer tank body 21 and the buffer tank body 31 fail or need to be cleaned, the transfer tank body 21 and the buffer tank body 31 can be easily moved to an open area for maintenance or cleaning. The moving process saves a lot of labor and time cost, reduces the difficulty of the maintenance or cleaning process, and can also avoid the situation that the remaining mechanisms are touched during the maintenance or cleaning process to cause damage to the mechanisms. Specifically, the frame body 11 in the embodiment is a bearing frame, and the number of the moving members 12 is six. The six moving members 12 are equally arranged in two rows on the two side edges of the bottom of the frame body 11. The moving members 12 in the embodiment are universal wheels.
[0030] Referring back to Figure 2 , preferably, the transfer mechanism 2 further comprises a feeding pipeline 23 and a magnetic pipeline 24. One end of the feeding pipeline 23 is a feeding port, the other end of the feeding pipeline 23 is in communication with one end of the magnetic pipeline 24, and the other end of the magnetic pipeline 24 is in communication with the transfer tank body 21. In specific application, one end of the feeding pipeline 23 is a feeding port, which is in communication with a slurry mixing mechanism. The slurry enters the transfer tank body 21 for transfer after passing through the feeding pipeline 23 and the magnetic pipeline 24 from the slurry mixing mechanism. By arranging the magnetic pipeline 24, when the slurry passes through the magnetic pipeline 24, the ferromagnetic impurities in the slurry are removed, avoiding the impurities from polluting the slurry in the transfer tank body 21 and the buffer tank body 31, and improving the coating quality. Specifically, a plurality of magnetic blocks with high magnetic induction strength are arranged on the inner wall of the magnetic pipeline 24, and a dense magnetic field region is formed in the magnetic pipeline 24. When the slurry passes through the magnetic pipeline 24, the ferromagnetic impurities in the slurry are adsorbed on the magnetic blocks to be removed. The feeding pipeline 23 is a feeding pipeline, which is provided with a feeding pump for providing power for the flow of the slurry.
[0031] Referring back to Figure 3 and Figure 4 , Figure 3Structure diagram of the transfer tank and the filtering mechanism in the embodiment, Figure 4 The transfer cover 212 is arranged on the transfer tank 211, and the first stirring member 22 is arranged on the transfer cover 212, and a stirring end of the first stirring member 22 extends into the transfer tank 211. In a specific application, the first stirring member 22 comprises a stirring driving motor, a stirring rod and stirring blades. The stirring driving motor is arranged on a surface of the transfer cover 212, and a driving end of the stirring driving motor is connected to one end of the stirring rod. The other end of the stirring rod extends into the transfer tank 211 through the transfer cover 212, and the stirring blades are arranged on the other end of the stirring rod. Through the arrangement of the first stirring member 22, the slurry in the transfer tank 211 can be stirred to avoid precipitation of the slurry. Through the arrangement of the first lifting part 213, the transfer cover 212 can be driven to rise or fall. That is, when the first lifting part 213 drives the transfer cover 212 to rise, the transfer cover 212 is away from the transfer tank 211, so that the inside of the transfer tank 211 can be conveniently cleaned, maintained or repaired. When the first lifting part 213 drives the transfer cover 212 to fall, the transfer cover 212 can be sealed on the transfer tank 211 to ensure the air tightness of the inside of the transfer tank 211. In this way, the process of manually lifting the transfer cover 212 is avoided, the labor cost is saved, and the safety is improved.
[0032] Reference is made to Figure 4 , preferably, the first lifting part 213 comprises a lifting driving body 2131 and a lifting frame 2132. The driving end of the lifting driving body 2131 is connected to the lifting frame 2132, the lifting frame 2132 is slidingly arranged on the frame member 11, and the transfer cover 212 is arranged on the lifting frame 2132. In a specific application, vertical sliding rails are arranged on the frame member 11, and a sliding block is connected to the lifting frame 2132. The sliding block is slidingly connected to the sliding rails. The lifting driving body 2131 drives the lifting frame 2132 to rise or fall, and the sliding block relatively slides on the sliding rails to improve the stability of the movement of the lifting frame 2132. The lifting frame 2132 drives the transfer cover 212 to rise or fall. Specifically, the lifting driving body 2131 is a lifting cylinder which is arranged at the bottom of the lifting frame 2132, and a push rod of the lifting cylinder is connected to the bottom of the lifting frame 2132. Further, the transfer tank member 21 further comprises a pressure balance valve 215 which is arranged on the transfer cover 212. When positive pressure or negative pressure occurs in the inside of the transfer tank 211, the pressure balance valve 215 can balance the air pressure inside and outside the transfer tank 211, that is, the pressure relief or pressurization is realized, so that the abnormal air pressure in the inside of the transfer tank 211 does not affect the coating operation.
[0033] Reference is made to Figure 4, preferably, the transfer tank body part 21 further comprises a locking part 214, the locking part 214 is arranged on the lifting frame 2132, the frame body part 11 is provided with a locking hole 111, the locking end of the locking part 214 extends into the locking hole 111, so that the lifting frame 2132 is locked to the frame body part 11. Through the setting of the locking part 214, after the transfer cover 212 is lifted to a certain height, mechanical locking is performed, preventing the lifting frame 2132 and the transfer cover 212 from being lifted too high to cause accidental falling and thus causing unnecessary injury accidents. The top of the frame body part 11 is provided with a cross beam, and the locking hole 111 is arranged on the cross beam. When the lifting frame 2132 and the transfer cover 212 are lifted to a predetermined height, that is, the transfer cover 212 is opened, the locking end of the locking part 214 can extend into the locking hole 111 to achieve locking, so that the lifting frame 2132 and the transfer cover 212 are locked on the frame body part 11 to achieve position fixing, which can effectively prevent the lifting frame 2132 and the transfer cover 212 from accidentally falling due to lifting drive body 2131 failure or improper operation of personnel, and thus prevent the occurrence of situations such as worker casualties and equipment damage. Specifically, the locking part 214 comprises a rotating handle and a locking column, the rotating handle is connected to one end of the locking column, the locking column is screwed through the lifting frame 2132, and the other end of the locking column extends towards the cross beam after passing through the lifting frame 2132. It can be understood that when the lifting frame 2132 and the transfer cover 212 are lifted to a predetermined height, rotating the rotating handle drives the other end of the locking column to gradually approach the cross beam until it extends into the locking hole 111 to achieve locking. In the embodiment, the structure of the buffer tank body part 31 is similar to that of the transfer tank body part 21, and the structure of the second stirring part 32 is similar to that of the first stirring part 22, which will not be described here. Further, the transfer tank body part 21 further comprises a liquid level sensor for real-time monitoring of the liquid level in the transfer tank 211. The surface of the transfer cover 212 is provided with an observation window for daily observation of the slurry storage state.

Through the setting of the first filtering part 52, non-ferromagnetic large particles and other impurities in the slurry can be filtered out, ensuring uniform slurry flowability, defect-free coating surface, and protecting precision components such as coating heads from wear, thereby further improving coating quality. Specifically, the first filtering part 52 is a slurry filtering mechanism, and a filter element is arranged inside the first filtering part 52. When the slurry flows through the first filtering part 52, the first filtering part 52 filters the slurry to intercept particles with excessive particle size.
[0035] Referring to Figures 3-5Preferably, the feeding mechanism 4 comprises a feeding pipe 41 and a second filter 42, the feeding pipe 41 is in communication with the buffer tank 31, and the second filter 42 is arranged in the feeding pipe 41. Through the arrangement of the second filter 42, the slurry can be filtered for the second time, and the non-ferromagnetic large particles and other impurities in the slurry can be further filtered and removed, so as to improve the coating quality. Specifically, the structure of the second filter 42 is similar to that of the first filter 52, which will not be described here.
[0036] Referring back to Figures 3-5 Preferably, the feeding pipe 41 comprises a first feeding pipe 411, a second feeding pipe 412, and a flow control valve 413, one end of the first feeding pipe 411 is in communication with the buffer tank 31, and the flow control valve 413 is in communication with the other end of the first feeding pipe 411 and the second feeding pipe 412, respectively. Through the arrangement of the flow control valve 413, the flow of the slurry can be adjusted to meet the flow requirements of different working conditions. Specifically, the feeding pipe 41 further comprises a screw pump and a pressure monitor, the screw pump acts on the second feeding pipe 412 to provide power output for the output of the slurry from the buffer tank 31 to the coating head. The pressure monitor is arranged in the second feeding pipe 412. The screw pump can control the number of revolutions through PLC, so as to control the pressure and flow of the second feeding pipe 412, and the pressure monitor can be used for closed-loop control operation, which will not be described here. Further, the flow control valve 413 and the first feeding pipe 411 are detachably connected, specifically, they can be screwed, and the flow control valve 413 and the second feeding pipe 412 are also detachably connected, so that the first feeding pipe 411 and the second feeding pipe 412 can be completely opened and closed by detaching the flow control valve 413, which is convenient for pipeline maintenance and daily maintenance. The structure of the transfer pipe 51 in the embodiment is similar to that of the feeding pipe 41, which will not be described here.
[0037] In summary, through the arrangement of the moving part 12, the position of the frame 1 and the transfer tank 21 and the buffer tank 31 arranged thereon can be moved, the flexibility of the mechanism is improved, especially when the transfer tank 21 and the buffer tank 31 fail or need to be cleaned, the transfer tank 21 and the buffer tank 31 can be easily moved to an open area for maintenance or cleaning, the moving process saves a lot of manpower and time cost, reduces the difficulty of the maintenance or cleaning process, and also avoids the situation that the remaining mechanisms are damaged during the maintenance or cleaning process.
