DETAILED DESCRIPTION

[0023] The technical scheme of the utility model will be further specifically explained below by examples in combination with the drawings.

[0024] Embodiment:

[0025] At present, in the production process of lead-acid storage batteries, the main ways of plate grid coating are drum-type plate coater and belt-type plate coater. Although these two kinds of plate coaters have been widely used in practical application, there are still some problems that cannot be ignored, such as the uniformity, efficiency, operation stability of paste coating and the optimization of equipment structure, etc. There is still room for improvement. The utility model provides a continuous plate grid double-sided plate coater for lead-acid storage batteries, which can not only realize double-sided paste coating operation of plate grid, but also improve the consistency and uniformity of paste coating, reduce the failure rate of equipment and operation difficulty through reasonable design structure. The utility model comprises a rack 1, one end of the rack is provided with an upper grid assembly 2 and a main control face box 3, the top end of the main control face box 3 is provided with an alarm lamp 4, the rack is also provided with a lower paste amount adjusting device 7 and a paste hopper pressing cylinder 26, the side surface of the paste hopper pressing cylinder 26 is provided with a paste hopper horizontal adjustment screw 5 and a paste hopper pressing device 6 installed above the paste hopper horizontal adjustment screw 5.

[0026] The rack 1 is the support structure of the whole device, one end of which is provided with the upper grid assembly 2 and the main control face box 3. The main control face box 3 is the core control area of the device, and the top end thereof is further provided with an alarm lamp 4 for alarming abnormal conditions during the operation of the device, so as to facilitate the operator to find problems in time and make adjustment or shutdown inspection. The lower paste amount adjusting device 7 and the paste pot pressing cylinder 26 are further provided on the whole rack, and the side surface of the paste pot pressing cylinder 26 is further provided with a paste pot horizontal adjusting screw 5, which can accurately adjust the paste pot in the horizontal direction, so as to ensure that the working state of the paste pot is always in the best position. In addition, the paste pot pressing device 6 is installed above the paste pot horizontal adjusting screw 5, and the operator can accurately control the paste amount through the device, so as to accurately manage the paste thickness of the grid.

[0027] The bottom end of the lower paste amount adjusting device 7 is provided with a paste pot 8, which is a main container for containing paste. The bottom of the lower paste amount adjusting device 7 is provided with an upper paste blocking plate 32 and a lower paste blocking plate 33 opposite to each other. The gap between the upper paste blocking plate 32 and the lower paste blocking plate 33 directly determines the distribution state of the paste on the grid, so the design of this part is particularly important. In order to prevent the leakage or waste of excess paste, the bottom of the lower paste blocking plate 33 is further provided with a surplus paste tank 34 for collecting excess paste, so as to realize the recycling of the paste, thereby reducing material waste and improving the economy and environmental protection of production.

[0028] The side surface of the lower paste amount adjusting device 7 is provided with a stirring roller hydraulic pump 23, a lower paste roller hydraulic pump 24 installed below the stirring roller hydraulic pump 23, and a back coating roller hydraulic pump 25 installed below the lower paste roller hydraulic pump 24. The purpose of these hydraulic pumps is to provide sufficient power support for the paste coating process, and through the accurate control of the hydraulic pump, it is ensured that the running speed and pressure of the stirring roller, the lower paste roller and the back coating roller during the paste coating process can meet the process requirements. The stirring roller hydraulic pump 23 is located above the whole device, which drives the stirring roller to fully stir the paste, so that the paste reaches a uniform state before coating, thereby ensuring the coating quality. The lower paste roller hydraulic pump 24 is installed below the stirring roller hydraulic pump 23, which mainly provides power for the lower paste roller, so that the paste can be smoothly coated on the surface of the grid. The back coating roller hydraulic pump 25 is located below the lower paste roller hydraulic pump 24, which drives the back coating roller to complete the paste coating operation on the back surface of the grid, thereby realizing the paste coating on both surfaces of the grid.

[0029] The outlet end of the paste amount adjusting device 7 is provided with a porous conveying belt 9. The main function of the porous conveying belt 9 is to convey the completed pasted grid to the next process, and its porous structure helps to remove the excess paste, thereby further improving the uniformity of the pasting.

[0030] The porous conveying belt 9 is provided with a paste bucket lifting adjusting device 10 below, which is connected with the grid over-pasting amount adjusting device 11. This device can flexibly adjust the distance between the paste bucket and the grid according to production needs, thereby accurately controlling the thickness of the pasting. This design not only improves the precision of the coating, but also effectively reduces material waste and improves production efficiency. More importantly, the paste bucket lifting adjusting device 10 is closely connected with the grid over-pasting amount adjusting device 11, and through this linkage system, fine control of the pasting amount can be realized to ensure that the coating amount of each grid reaches the best state, which is of great significance to improve the overall performance of the battery.

[0031] The porous conveying belt 9 is provided with a coated grid paper pressing roller 14. The function of the coated grid paper pressing roller 14 is to make the pasting more uniform by applying certain pressure on the surface of the grid during the pasting process, and to remove excess paste to avoid the occurrence of too thick or too thin coating. This design not only improves the flatness of the grid, but also enhances the bonding force between the coating and the grid substrate, which has a significant effect on improving the cycle life and electrochemical performance of the battery.

[0032] The outlet end of the porous conveying belt 9 is provided with a belt conveying gearbox 19, which is responsible for driving the conveying belt. The side of the belt conveying gearbox 19 is provided with a grid thickness adjusting screw 15, which realizes accurate control of the thickness of the grid. The uniformity and consistency of the thickness of the grid is one of the key factors affecting the performance of the battery. Through this adjusting device, the thickness of each grid can be ensured to be within the designed range, thereby improving the production consistency and reliability of the battery.

[0033] The side of the belt conveying gearbox 19 away from the porous conveying belt 9 is also provided with a waste cutter 16. The purpose of this design is to timely cut off unqualified grids or production waste during the production process to avoid affecting the subsequent production links. The setting of the waste cutter 16 not only improves the continuity and stability of the production process, but also reduces manual intervention and reduces production costs.

[0034] The bottom of the porous conveying belt 9 is also provided with a conveying belt motor 20 for providing power for the whole conveying system. The performance of the conveying belt motor 20 directly affects the running speed and stability of the conveying belt, so in the design, special attention is paid to the power matching and operation efficiency of the motor, so as to ensure that the motor can still maintain a good working state under the condition of high load and long time operation. Through a series of design optimization, the lead-acid storage battery continuous grid double-sided coating machine provided by the utility model not only realizes significant improvement in coating quality and production efficiency, but also reaches a new height in automation degree and operation simplicity, and brings revolutionary improvement for the manufacturing process of lead-acid storage batteries.

[0035] In summary, the lead-acid storage battery continuous grid double-sided coating machine provided by the utility model realizes the overall optimization of the coating process through the cooperative work of the key components such as the porous conveying belt 9, the paste hopper lifting adjusting device 10, the grid overcoating amount adjusting device 11, the coating paper compression roller 14, the belt transmission gearbox 19, the grid thickness adjusting screw 15, the waste cutter 16 and the conveying belt motor 20. This innovative technology not only brings higher efficiency and quality for the production of lead-acid storage batteries, but also provides new power for the technical progress and development of related industries.

[0036] The machine frame is also provided with a coating paper hanging rack 12 on one side for placing and fixing the coating paper. The coating paper hanging rack 12 is not a simple fixing device, and the coating paper hanging rack 12 is provided with a coating paper tensioning mechanism 13. This mechanism can apply appropriate tension to the coating paper during the pasting process, so that the coating paper can always remain flat and stable, and will not affect the uniformity and efficiency of the pasting due to slackness or tightness. The flatness of the coating paper plays an important role in the quality of the pasting, so the design of the tensioning mechanism is meticulous, which provides reliable guarantee for the stable operation of the whole equipment.

[0037] The machine frame is also provided with a coating paper hanging rack 12 on one side for placing and fixing the coating paper. The coating paper hanging rack 12 is not a simple fixing device, and the coating paper hanging rack 12 is provided with a coating paper tensioning mechanism 13. This mechanism can apply appropriate tension to the coating paper during the pasting process, so that the coating paper can always remain flat and stable, and will not affect the uniformity and efficiency of the pasting due to slackness or tightness. The flatness of the coating paper plays an important role in the quality of the pasting, so the design of the tensioning mechanism is meticulous, which provides reliable guarantee for the stable operation of the whole equipment.

[0038] The mechanism side where the paste hopper lifting adjusting device 10 is located is also provided with a polar plate over-coating amount adjusting scale 18, which can directly display the current coating thickness and the set value, so as to facilitate the operator to quickly adjust according to the production requirements, and ensure the accuracy and consistency of the coating thickness. Through this design, the coating thickness of the polar plate can not only be effectively controlled, but also reduce the material waste or performance problems caused by excessive or insufficient coating. The other side of the mechanism where the paste hopper lifting adjusting device 10 is located is provided with a vacuum pump buffer tank 21, which is connected with the vacuum pump 28 through a pipeline, and the vacuum pump 28 is fixed on the edge of the table surface of the rack 1. The function of the vacuum pump 28 is to provide the necessary negative pressure condition for the coating process, so as to enhance the adhesion and uniformity of the coating. The addition of the vacuum pump buffer tank 21 is to alleviate the pressure fluctuation that may be generated when the vacuum pump is running, so as to ensure the stability of the negative pressure system. In this way, the effect of the grid coating is more uniform, and the adhesion of the coating layer is stronger, which further improves the quality of the product.

[0039] The upper and lower surfaces of the inlet end of the porous conveying belt 9 are provided with symmetrical conveying belt negative pressure interfaces 22. The setting of these interfaces is to fix and stabilize the conveying belt through negative pressure, so that the conveying belt will not deviate or slip during operation, thereby ensuring the continuity and reliability of the coating process. The porous conveying belt 9 bears the heavy responsibility of grid conveying in the entire device, and its stable operation is directly related to the efficiency and quality of the coating. Therefore, the design of the conveying belt negative pressure interface 22 provides strong support for the efficient operation of the coating device.

[0040] The bottom side of the rack 1 is provided with a hydraulic distribution box 29, the top of which is connected with the paste hopper tilting hydraulic cylinder 27, and the bottom thereof is connected with the outside through the liquid inlet pipe 30 and the liquid return pipe 31. The function of the hydraulic distribution box 29 is to reasonably distribute and adjust the hydraulic system, so that the tilting angle of the paste hopper can be accurately adjusted according to the actual needs. This design makes the coating process of the paste hopper more flexible, and can better adapt to different types of grids and coating requirements. Moreover, the introduction of the hydraulic system greatly reduces the complexity of manual operation, and improves the automation level and production efficiency of the device.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
