Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery plate production technology, specifically to a scraping device for a lead-acid battery plate coating machine. Background Technology

[0002] In the manufacturing process of lead-acid batteries, lead paste is applied to the grids using rollers on a coating machine to form the initial shape of the green plate. During the rolling process, the lead paste on the grid surface is squeezed, and excess lead paste overflows to both sides, exceeding the grid body. Because lead paste is viscous, the excess paste that overflows to both sides does not fall off naturally and continues to be transported downstream with the conveyor belt. This excess paste needs to be cleaned and recycled during the coating stage. Once it flows into the next process, it not only causes irreversible waste of lead paste but also affects the structure of the entire green plate after drying. The current method is to manually scrape off the excess paste from the sides of the grid after coating, which is inefficient and wastes manpower.

[0003] To address the aforementioned technical problems, patent document CN207338523U discloses a scraping device for a lead-carbon battery coating machine. This device includes a fixed frame located above the conveyor belt of the coating machine. Scraping rods are respectively installed above the two side edges of the conveyor belt. The upper ends of the scraping rods are fixed to the fixed frame, and the lower ends are lower than the conveyor belt body. The rod body contacts the edge of the conveyor belt. The fixed frame is located downstream of the coating machine's rollers. The scraping rods are made of steel wire, and the upper ends of the steel wires are clamped into positioning grooves on the circumference of a crossbar. Multiple positioning grooves are located at both ends of the crossbar and are arranged at equal intervals along the length of the crossbar. When scraping edges of plates of different widths, the position of the steel wire needs to be adjusted. The upper ends of the steel wires are clamped into the positioning grooves on the circumference of the crossbar, making wire adjustment inconvenient. Meanwhile, after the steel wire scrapes off the excess lead paste at the edge of the grid, the lead paste at the edge of the grid is prone to loosening and expanding in the direction of grid thickness, which leads to a decrease in the density of lead paste at the edge of the grid.

[0004] Patent document CN207269036U discloses a device for removing residual paste from the edges of lead-carbon battery grids in a coating machine. Downstream of the coating machine's rollers, a blower is installed. The blower includes left and right scrapers, positioned against the left and right edges of the coating machine's conveyor belt, respectively. The blower also includes left and right air pipes with their outlets facing downwards, directly opposite the left and right edges of the conveyor belt. The outlets of the left and right air pipes are in a straight line and connected to an air pump. Scrapers and blowers are located on both sides of the coating machine's conveyor belt. Grids coated with lead paste pass sequentially through the scrapers and blowers. The scrapers remove residual paste from the grid edges, while the blowers further clean the grid edges with air blades, blowing off any remaining residual paste. However, this technical solution also suffers from problems such as inconvenient scraper position adjustment and reduced lead paste density at the grid edges. Utility Model Content

[0005] The main purpose of this utility model is to provide a scraping device for a lead-acid battery coating machine that can scrape off excess lead paste from the side of the grid and smooth out the lead paste from the side of the grid.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] The scraping device for a lead-acid battery coating machine includes mounting seats fixed on both sides of the coating machine frame. A smooth rod is slidably mounted on the mounting seat. The sliding direction of the smooth rod is perpendicular to the conveying direction of the coating machine conveyor belt. Bolts are threaded onto the mounting seats and are parallel to the smooth rod. A scraper is fixed on the smooth rod and is connected to the bolts through an elastic connector. The scraper is in close contact with the side of the grid. A squeegee plate is fixed on the scraper above the grid. The end of the squeegee plate facing the material feeding direction of the grid is inclined upward.

[0008] Specifically, the scraper and squeegee are located downstream of the coating machine's pressure rollers.

[0009] Specifically, the elastic connector includes a square tube fixed to the scraper, the square tube being parallel to the bolt, a block being slidably disposed inside the square tube, the block being connected to the scraper via a spring, and the bolt being rotatably connected to the block.

[0010] Specifically, one end of the spring is fixedly connected to the block, and the other end of the spring is fixedly connected to the scraper.

[0011] Specifically, the length direction of the scraper is parallel to the conveying direction of the coating machine conveyor belt.

[0012] Specifically, the end face of the squeegee facing the grid is a smooth surface.

[0013] Specifically, the bolt is threaded with a lock nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By using a scraper to closely adhere to the side of the grid, excess lead paste overflowing after compression is automatically scraped off during the operation of the coating machine's conveyor belt, thus avoiding waste and structural problems caused by lead paste flowing into subsequent processes.

[0016] 2. By utilizing the sliding structure of the bolt and the guide rod, the position of the scraper can be easily adjusted to meet the needs of different width grids, thus solving the problem of inconvenient scraper adjustment in the existing technology.

[0017] 3. The elastic connector allows the scraper to move elastically with the conveyor belt offset, always keeping it close to the side, and adaptively compensating for the offset of the side of the conveyor belt to ensure stable and reliable scraping effect.

[0018] 4. A smoothing plate is added to smooth the lead paste on the sides of the grid after scraping, preventing loosening and density reduction, thus improving the quality of the green plate.

[0019] 5. The entire device is integrated downstream of the coating machine, replacing manual operation, reducing labor waste, optimizing lead paste recycling, and improving overall production efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1-3 As shown, the scraping device of the coating machine for lead-acid batteries includes mounting seats 5 fixed on both sides of the coating machine frame 1. A smooth rod 8 is slidably mounted on the mounting seat 5, and the sliding direction of the smooth rod 8 is perpendicular to the conveying direction of the coating machine conveyor belt 2.

[0026] The mounting base 5 is threaded with a bolt 9, and the bolt 9 is threaded with a lock nut. The bolt 9 is parallel to the smooth rod 8.

[0027] A scraper 6 is fixed on the smooth rod 8. The scraper 6 is connected to the bolt 9 through an elastic connector. The scraper 6 is close to the side of the grid 3. The length direction of the scraper 6 is parallel to the conveying direction of the coating machine conveyor belt 2. The scraper 6 is located downstream of the coating machine pressure roller 4.

[0028] The elastic connector includes a square tube 11 fixed on the scraper 6, the square tube 11 being parallel to the bolt 9, a block 10 being slidably disposed inside the square tube 11, the block 10 being connected to the scraper 6 via a spring 12, one end of the spring 12 being fixedly connected to the block 10, the other end of the spring 12 being fixedly connected to the scraper 6, and the bolt 9 being rotatably connected to the block 10.

[0029] After being coated, the grid 3 conveyed by the coating machine conveyor belt 2 is squeezed by the coating machine pressure roller 4. Excess lead paste on the grid 3 will move to the left and right sides of the grid 3 and bulge to the outside of the grid 3.

[0030] In this embodiment, by setting scraper 6, when scraping off excess lead paste on the left and right sides of the grid 3, the bolts 9 on the left and right sides are rotated respectively, so that the scraper 6 on the left and right sides slides into contact with the sides of the grid 3 respectively. Then, the locking nut is rotated so that the locking nut is pressed against the mounting seat 5. During the process of the grid 3 being conveyed by the coating machine conveyor belt 2, the scraper 6 can scrape off the excess lead paste on the sides of the grid 3.

[0031] The position of the scraper 6 can be adjusted by bolt 9. The position adjustment of the scraper 6 is convenient and can be applied to gratings 3 of different widths.

[0032] By incorporating a flexible connecting element, the scraper 6 can move towards its mounting base 5 on one side. For example... Figure 1 As shown, when the grid 3 shifts to the left during the conveying process, the scraper 6 on the left is squeezed and the elastic connector on the left is compressed. Meanwhile, the scraper 6 on the right can always stick to the right side of the grid 3 under the elastic force of the elastic connector on the right, which can ensure that the scraper 6 always scrapes off the excess lead paste on the side of the grid 3.

[0033] Example 2: Based on Example 1, referring to... Figures 1-3 As shown, a sizing plate 7 is fixed on the scraper 6 above the grid 3. The end of the sizing plate 7 facing the material feeding direction of the grid 3 is inclined upward, and the sizing plate 7 is located downstream of the pressure roller 4 of the coating machine. The end face of the sizing plate 7 facing the grid 3 is a smooth surface.

[0034] By setting a smearing plate 7, after the side of the grid 3 passes under the smearing plate 7, the smearing plate 7 can smooth the lead paste on the side of the grid 3, ensuring the density of the lead paste on the side of the grid 3. The smearing plate 7 and the scraper 6 move together, ensuring that the lead paste on the side of the grid 3 is always smoothed.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
