Description

Technical Field

[0001] This application relates to the field of lead paste cleaning technology, specifically an online lead paste cleaning mechanism for the surface of a pressure roller. Background Technology

[0002] In the production process of lead-acid batteries, the quality of the plates is crucial to the battery performance and lifespan. When the plates pass through the pressure rollers after leaving the drying kiln, some residual paste will stick to the surface of the pressure rollers. If it is not cleaned in time, it will cause the plates to stick to the paste and become unusable.

[0003] A search revealed that patent CN222198013U discloses a lead paste cleaning device for lead-acid battery production pressure rollers. The device includes a conveying device and a support mounted on the conveying device. A pressure roller is installed inside the support. A base frame is installed at the lower end of the conveying device, and a connecting plate is provided at the upper end of the support. A baffle is installed at the connecting plate, and a cleaning mechanism is provided inside the baffle. The cleaning mechanism includes a storage tank, and the baffle has a groove. The storage tank is movably connected to the groove, and a lifting component is provided at the upper end of the storage tank. This invention utilizes a cloth roller that rotates due to friction, wiping a thin film off the surface of the pressure roller. Some of the removed residue falls into a waste bin via a conveyor belt on the surface of the conveying device for centralized recycling. This eliminates the need for manual contact, preventing lead paste from contacting the skin and causing harm, reducing the workload of workers, and providing a more thorough cleaning of the pressure roller surface, thus extending the roller's service life.

[0004] The above solution involves cleaning lead paste from a single pressure roller on the conveyor. However, in reality, the battery plates (electrodes) do not simply move on the conveyor. Instead, they pass between two sets of pressure rollers (or other forms of extrusion devices). The lead paste is evenly applied to the battery plates through the extrusion action of the pressure rollers. Therefore, the upper and lower sets of pressure rollers are usually cleaned simultaneously, which makes the above cleaning solution no longer applicable. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art by proposing an online lead paste cleaning mechanism for the surface of the pressure roller, so as to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides an online lead paste cleaning mechanism for pressure roller surfaces, including a device platform. A motor is fixedly installed on the device platform, and a fixed roller shaft is fixedly connected to the output end of the motor. A fixed pressure roller is fixedly sleeved on the outer surface of the fixed roller shaft. A cylinder is fixedly installed on the top of the device platform, and a slide is fixedly connected to the output end of the cylinder. The outer surface of the slide is slidably connected to the inner side of the device platform. A movable roller shaft is rotatably connected to the inner surface of the slide. A movable pressure roller is fixedly sleeved on the outer surface of the movable roller shaft. A linkage brushing mechanism for simultaneously cleaning the fixed pressure roller and the movable pressure roller is provided on the device platform. A water spraying mechanism is provided on the device platform. A collection tank is provided on the device platform, located below the movable pressure roller, to collect the generated waste (lead paste and waste liquid, etc.).

[0007] Preferably, the linkage brushing mechanism includes a first large gear fixedly connected to the end of the fixed roller shaft away from the motor, a fixed rotating shaft rotatably connected to the inner surface of the device platform, and a first small gear fixedly connected to the end of the fixed rotating shaft near the first large gear, and the first small gear meshing with the first large gear. The linkage brushing mechanism can clean the lead paste remaining on the fixed pressure roller and the moving pressure roller after the lead coating is completed.

[0008] Preferably, a second large gear is fixedly connected to one end of the moving roller shaft near the first large gear, a connecting plate is fixedly connected to the outer surface of the slide block, and a moving shaft is rotatably connected to the inner surface of the connecting plate.

[0009] Preferably, a second pinion is fixedly connected to one end of the rotating shaft near the second large gear, and the outer surface of the second pinion meshes with the second large gear.

[0010] Preferably, both the fixed rotating shaft and the movable rotating shaft are provided with a storage base on their outer surfaces. A rod is movably inserted into the storage base, and a brush handle is movably inserted into the inner side of the storage base. The outer surface of the brush handle is provided with a first positioning hole and a second positioning hole, respectively.

[0011] Preferably, the water spraying mechanism includes a water storage tank fixedly installed on the device platform, a water pump fixedly installed on the water storage tank, and a water pipe fixedly connected to the output end of the water pump. The water spraying mechanism can assist in spraying water when the brush handles the two sets of pressure rollers, thereby improving the cleaning effect.

[0012] Preferably, a triangular water tray is fixedly installed on the top of the device platform, and one end of the triangular water tray is fixedly connected to the end of the water pipe away from the water pump. Several sets of nozzles with different angles are provided on the triangular water tray.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This online lead paste cleaning mechanism for the pressure roller surface achieves simultaneous brushing and cleaning of both the stationary and moving pressure rollers by meshing the first and second large gears and linking the second small gear. In conjunction with the introduced water pump and water tank, water is sprayed onto the brushing area of ​​the brush handle through water pipes and nozzles on the triangular water pan, achieving wet rinsing of the pressure roller surface. This linked dynamic cleaning method not only enhances the cleaning effect but also helps to remove stubborn lead paste residue.

[0015] 2. This online pressure roller surface lead paste cleaning mechanism can precisely adjust the height of the moving pressure roller by lifting the slide block with a cylinder to adapt to the needs of electrode plates of different thicknesses. At the same time, before lead coating, the position of the brush handle in the storage seat is adjusted, achieving the dual function of avoiding interference with lead coating and effectively cleaning the pressure roller. This design not only ensures the smooth progress of the lead coating process, but also ensures the cleanliness of the pressure roller surface and extends the service life of the equipment.

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-5 An online lead paste cleaning mechanism for pressure rollers includes a platform 1, on which a motor 2 is fixedly mounted. A fixed roller shaft 3 is fixedly connected to the output end of the motor 2. A fixed pressure roller 4 is fixedly sleeved on the outer surface of the fixed roller shaft 3. The position of the fixed pressure roller 4 remains unchanged. A cylinder 5 is fixedly mounted on the top of the platform 1. A slide 6 is fixedly connected to the output end of the cylinder 5. The outer surface of the slide 6 is slidably connected to the inner side of the platform 1. A movable roller shaft 7 is rotatably connected to the inner surface of the slide 6. A movable pressure roller 8 is fixedly sleeved on the outer surface of the movable roller shaft 7. The height of the movable pressure roller 8 is adjustable. A linkage brushing mechanism for simultaneously cleaning the fixed pressure roller 4 and the movable pressure roller 8 is provided on the platform 1. A water spraying mechanism is provided on the platform 1. A collection tank 26 is provided on the platform 1.

[0024] Through the above technical solution, during the process of applying lead paste to the electrode plates on the production line, the device can first move the slide block 6 up and down by the cylinder 5 until the moving roller shaft 7 is adjusted to a suitable height so that electrode plates of different thicknesses can pass through the area between the fixed pressure roller 4 and the moving pressure roller 8 and receive lead coating treatment from the two sets of pressure rollers (the surfaces of the fixed pressure roller 4 and the moving pressure roller 8 are uniformly coated with lead paste beforehand). After the lead coating is completed, the cylinder 5 moves the second large gear 12 at the end of the fixed pressure roller 4 down to the height where it meshes with the first large gear 9. At the same time, the linkage brushing mechanism cooperates with the water spraying mechanism to perform a brushing operation on the surfaces of the fixed pressure roller 4 and the moving pressure roller 8. (It should be noted that before the lead coating operation, the brush handle 18 must be stably stored in the storage seat 16, that is, the brush handle 18 is not in contact with the two sets of pressure rollers. After the lead coating is completed, the brush handle 18 is moved out so that it re-contacts the two sets of pressure rollers.)

[0025] Specifically, the linkage brushing mechanism includes a first large gear 9 fixedly connected to the end of the fixed roller shaft 3 away from the motor 2, a fixed rotating shaft 10 rotatably connected to the inner surface of the device platform 1, a first small gear 11 fixedly connected to the end of the fixed rotating shaft 10 near the first large gear 9, and the first small gear 11 meshing with the first large gear 9.

[0026] With the above technical solution, both the fixed roller shaft 3 and the fixed rotating shaft 10 can rotate through the device platform 1. When the first large gear 9 rotates, it will be linked with the first small gear 11 to rotate synchronously.

[0027] Specifically, a second large gear 12 is fixedly connected to one end of the moving roller shaft 7 near the first large gear 9, a connecting plate 13 is fixedly connected to the outer surface of the slide block 6, and a moving shaft 14 is rotatably connected to the inner surface of the connecting plate 13.

[0028] Through the above technical solution, as the position of the second large gear 12 changes accordingly with the follower roller 7 and the slide 6, the connecting plate 13 will drive the rotating shaft 14 to make synchronous height adjustments.

[0029] Specifically, a second pinion 15 is fixedly connected to one end of the rotating shaft 14 near the second large gear 12, and the outer surface of the second pinion 15 meshes with the second large gear 12.

[0030] With the above technical solution, when the second large gear 12 rotates, it will be linked with the second small gear 15 to rotate accordingly. However, the second large gear 12 can only be driven to rotate when it is adjusted to the position of meshing with the first large gear 9.

[0031] Specifically, both the fixed rotating shaft 10 and the movable rotating shaft 14 are provided with a storage seat 16 on their outer surfaces. A rod 17 is movably inserted into the storage seat 16. A brush handle 18 is movably inserted into the inner side of the storage seat 16. The outer surface of the brush handle 18 is provided with a first positioning hole 19 and a second positioning hole 20, respectively.

[0032] Through the above technical solution, the diameters of the first positioning hole 19 and the second positioning hole 20 are exactly the same, and are basically the same as the diameter of the insertion rod 17. This is so that when the insertion rod 17 is simultaneously inserted into the storage base 16 and the first positioning hole 19 or the second positioning hole 20, the brush handle 18 inserted into the storage base 16 at different depths can be stably limited.

[0033] Specifically, the water spraying mechanism includes a water storage tank 21 fixedly installed on the device platform 1, a water pump 22 fixedly installed on the water storage tank 21, and a water pipe 23 fixedly connected to the output end of the water pump 22.

[0034] Through the above technical solution, the water pump 22 can pump the water in the water storage tank 21 into the water pipe 23, and finally deliver it into the triangular water tray 24, where it is sprayed out by the nozzle 25.

[0035] Specifically, a triangular water tray 24 is fixedly installed on the top of the device platform 1, and one end of the triangular water tray 24 is fixedly connected to the end of the water pipe 23 away from the water pump 22. Several sets of nozzles 25 with different angles are provided on the triangular water tray 24.

[0036] The above technical solution involves designing nozzles 25 with different inclination angles on the triangular water pan 24 to expand the water spray angle, so that the water flow can basically cover the area around the two sets of pressure rollers and the two sets of rotating shafts after being sprayed, so that they can work together to achieve a scrubbing effect.

[0037] Working principle: During the lead paste application process on the electrode plates on the production line, the height of the moving pressure roller 8 is first adjusted according to the thickness of the battery electrode plate. This is achieved by lifting the slide block 6 via the cylinder 5. As the slide block 6 moves upward, it drives the moving roller shaft 7 and the moving pressure roller 8 to move upward synchronously until the area between the moving pressure roller 8 and the fixed pressure roller 4 is just wide enough for the electrode plate of the corresponding thickness to pass through. At this point, the second large gear 12 adjusts its height accordingly and gradually moves away from the first large gear 9. When the electrode plate passes between the fixed pressure roller 4 and the moving pressure roller 8 for lead coating, the motor 2 is activated to drive the fixed roller shaft 3 to rotate, which in turn causes the fixed pressure roller 4 to rotate, thus coating the passing electrode plate with lead. During this process, the first large gear 9 and the second large gear 12 are not meshed. There is no need to simultaneously drive the moving pressure roller 8 to rotate. During the rotation of the fixed pressure roller 4, the moving pressure roller 8 is simultaneously driven to rotate as the electrode plate moves (with the upper and lower surfaces of the electrode plate in stable contact with the moving pressure roller 8 and the fixed pressure roller 4 respectively), until the lead coating of the electrode plate is completed. It is important to note that before applying lead to the electrode plate during the rotation of the fixed pressure roller 4 and the moving pressure roller 8, the brush handle 18 must be inserted to its deepest position in the storage base 16. Specifically, the insertion rod 17 should be inserted into the first positioning hole 19 of the brush handle 18 in the storage base 16. At this point, the brush handle 18 is stabilized, and the portion protruding from the storage base 16 is minimized. Therefore, the brush handle 18 is not in contact with the fixed pressure roller 4 and the moving pressure roller 8, and thus, the lead coating on the brush handle 18 is not affected. The brush scrapes the lead paste off the two sets of pressure rollers during the lead coating process. After the lead coating operation on the electrode plate is completed, the insert rod 17 is pulled out and inserted into the second positioning hole 20 of the brush handle 18, so that the brush handle 18 extends further out of the storage seat 16. At this time, the brush handle 18 can contact the fixed pressure roller 4 and the moving pressure roller 8. At the same time, the height of the slide 6 is readjusted by the cylinder 5, so that the second large gear 12 moves down to the position of meshing with the first large gear 9. During this process, the connecting plate 13 drives the moving shaft 14, the second small gear 15 and the brush handle 18 to move down synchronously. Finally, the motor 2 is turned on to drive the fixed roller shaft 3 to rotate. During this process, the first large gear 9 rotates synchronously and is linked to the rotation of the first small gear 11, thereby passing through The rotation of the fixed shaft 10 causes the corresponding brush handle 18 to brush the surface of the fixed pressure roller 4 during rotation. At the same time, the first large gear 9 will drive the second large gear 12 to rotate, and the second large gear 12 will drive the second small gear 15 to rotate as well. That is, the rotating shaft 14 drives the corresponding brush handle 18 to brush the surface of the rotating pressure roller 8 during rotation, so that the lead paste on the surface of the two sets of pressure rollers can be brushed off at the same time. In order to improve the cleaning effect of the lead paste on the surface of the pressure roller, the water pump 22 can also pump the water in the water tank 21 into the water pipe 23, and finally deliver it to the triangular water tray 24. The various inclined nozzles 25 on the triangular water tray 24 spray the water onto the brushing area of ​​the brush handle 18.This allows the brush to effectively clean the 18 pairs of fixed pressure rollers 4 and moving pressure rollers 8, significantly improving the cleaning effect. Finally, the waste liquid falls into the collection tank 26 for subsequent unified treatment.

[0038] In summary, the innovative cleaning mechanism introduced in this application achieves simultaneous cleaning of the fixed pressure roller 4 and the moving pressure roller 8 through the dual function of the brush handle 18 and gear linkage cleaning. Before lead coating, the brush handle 18 is adjusted in position in the storage seat 16 to avoid interfering with the lead coating process and ensure the smooth progress of lead coating. During the cleaning process, the brush handle 18 is in close contact with the surfaces of the two sets of pressure rollers. Through the linkage of the corresponding gears, the water pump 22 sprays water from the water tank 21 onto the brushing area of ​​the brush handle 18, achieving comprehensive, thorough and uniform cleaning of the pressure roller surfaces.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
