Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery manufacturing, and in particular relates to a residual paste collecting device which can prevent residual coating paste from falling onto the surface of a polar plate. Background Art

[0002] The positive and negative plates are the main body of the electrochemical reaction in the lead-acid battery. The positive active material, negative active material and electrolyte in the lead-acid battery undergo electrochemical reactions through charging or discharging. During the reaction, the current is transmitted through the grid and bus, thereby realizing the charging and discharging of the battery. The manufacturing quality of the positive and negative plates has a great influence on the performance and life of the battery. At present, the manufacturing of lead-acid battery plates is divided into three major processes: mixing paste, coating and curing. The coating process is to combine the active material, grid and coating paper completed by mixing paste through coating equipment to form a wet raw plate. The wet raw plate is placed in a drying kiln for drying, and then collected and stacked. After that, it enters the curing room for curing to form a dry raw plate.

[0003] During the plate coating process, the prepared lead paste enters the coating machine head through the lower paste barrel. At this time, the grid and the lower coated paper are pressed under the coating machine head. The coating machine is running, and the lead paste is coated on the grid. Then, the upper coated paper is pressed on the surface of the plate through the rubber wheel, and then sliced ​​by the slicer to form a wet raw plate. Since the grid and lead paste are not compacted during the coating process, the grid, lead paste and coated paper are tightly combined after being pressed by the rubber wheel, and the excess lead paste will be squeezed out at the same time. The excess lead paste will adhere to the rubber wheel. In order to prevent the accumulation of lead paste from affecting normal production, a scraper strip will be installed on the outside of the rubber wheel to clean up the excess paste on the rubber wheel. The excess paste cleaned up needs to be collected by a collection device, and then the paste is reversed to reduce the loss of lead paste. The traditional residual paste collection device is a rectangular trough with equal heights on all four sides. Two rectangular holes are opened at the bottom of the trough near the left and right sides. In order to prevent the residual paste from falling onto the plate, the hole opening position avoids the top of the plate, and the residual paste falls from the hole into the residual paste collection box below. The residual paste collection device requires a certain amount of lead paste to accumulate before it will fall. When the residual paste accumulation height is higher than the collection device, a part of the residual paste will fall out of the collection device and directly fall onto the plate. After passing through the slitting machine, the residual paste will be compacted on the surface of the wet raw plate. After being assembled into a battery, it may puncture the partition, causing a short circuit in the battery, which seriously affects the use of the battery. Therefore, workers are required to clean the residual paste in the collection device regularly. Summary of the invention

[0004] The purpose of the present utility model is to provide a collecting device for preventing the dropping of excess paste onto the surface of the battery plate during the paste filling process of the battery plate, which can effectively prevent the quality problem of excess paste dropping onto the surface of the battery plate during the paste filling process of the battery plate. At the same time, it does not require workers to clean regularly, and only needs to be cleaned when it is found that the feeding port is blocked. This device not only reduces the workload of workers, but also effectively improves the filling quality and ensures the normal use of the battery.

[0005] The technical solution of the present utility model is: a collecting device for preventing the dropping of excess paste onto the surface of the battery plate, including a trough body composed of front and rear side walls, left and right side walls and a trough bottom, the trough bottom is provided with a discharge port, and the feature is that: a baffle connected to the side wall is provided above one of the front and rear side walls; a feeding slope cooperating with the discharge port is provided on the trough bottom below the feeding slope.

[0006] In the technical solution of the present utility model, assembly grooves for installation and cooperation with the paste filling machine are provided on the left and right sides of the trough body.

[0007] In the technical solution of the present utility model, the number of the discharge ports is two, which are respectively arranged on the left and right sides of the trough bottom; the number of the feeding slopes is two, which are symmetrically distributed on the trough bottom between the two discharge ports and are connected to the front and rear side walls of the trough body; the distance between the ends of the two feeding slopes is greater than the width of the paste filling plate belt.

[0008] In the technical solution of the present utility model, the included angle between the slope surface of the feeding slope and the horizontal plane is 45°.

[0009] In the technical solution of the present utility model, the intersection of the vertices of the two feeding slopes is at the same height as the upper part of the trough body, and the intersection of the slope vertices is rounded.

[0010] In the technical solution of the present utility model, the width of the baffle is the same as the width of the front and rear side walls of the trough body, and the height is slightly higher than the installation height of the paste scraping strip.

[0011] In the technical solution of the present utility model, the baffle is rectangular, and the two upper corners of the baffle are rounded.

[0012] In the technical solution of the present utility model, the feeding port is in the shape of an inverted trapezoidal table, and both sides of the feeding port are respectively connected to the end of the feeding slope and the left or right side wall of the trough body.

[0014] In the technical solution of the present utility model, the materials of the trough body, the baffle and the assembly groove are all stainless steel materials; a surplus paste collection box is also provided below the trough body.

[0015] Advantages of the present utility model: After installing the device of the present utility model under the rubber-coated wheel of the filling machine, the excess paste for filling drops onto the blanking slope. At this time, under the action of its own gravity, the excess paste will slowly fall along the blanking slope, and when new excess paste drops, it will also accelerate the falling speed. When the excess paste accumulates too much, the excess paste will be blocked by the baffle and will not fall onto the plate surface. Only at this time does the worker need to manually clean the excess paste to ensure the normal use of the device. This greatly reduces the workload of the worker for cleaning the excess paste and avoids the situation where the excess paste drops onto the plate when the excess paste accumulates too much.

[0016] The structure of the present utility model is simple, and processing and installation are convenient. It can effectively reduce the workload of workers for cleaning the excess paste, prevent the situation where the lead paste accumulates too much and drops onto the plate due to the worker forgetting to clean the excess paste, thereby improving the filling quality of the battery plate.

[0022] Now, the present utility model will be further described in detail with reference to the drawings.

[0023] As Figure 1 , Figure 2 shown, an embodiment of a device for preventing the excess paste for filling from dropping onto the plate surface is composed of a tank body 1 and a baffle 2, a blanking slope 3, a discharge port 4, and an assembly groove 5 provided on the tank body 1. The materials are all stainless steel materials, and it is mainly used to collect the excess paste during the plate filling process to avoid the excess paste dropping onto the plate.

[0024] The tank body 1 is composed of front and rear side walls, left and right side walls, and a tank bottom, and is matched with the battery plate filling machine and can be installed under the rubber-coated wheel of the plate filling machine. The heights of the front, rear side walls and the left and right side walls are all the same.

[0025] The baffle 2 is provided above the rear side wall of the trough 1 on the side away from the rubberized wheel above the trough body, and the lower part of the baffle 2 is connected to the top surface of the rear side wall of the trough 1. The width of the baffle 2 is the same as the width of the rear side wall of the trough 1, and the height is slightly higher than the installation height of the paste scraping strip 10. The baffle 2 is rectangular, and the two upper corners of the baffle 2 are rounded.

[0026] There are two blanking slopes 3, which are symmetrically distributed on both sides of the center line of the trough 1 and are connected to the front and rear side walls of the trough 1. The angle of the blanking slope 3 forms a 45° angle with the center line of the trough 1. The intersection of the vertices of the two blanking slopes 3 is at the same height as the upper part of the trough 1, and the intersection of the slope vertices is rounded. The distance between the ends of the two blanking slopes 3 is greater than the width of the coated plate belt, so as to prevent the remaining paste from falling onto the surface of the plate when it drops.

[0027] There are two blanking ports 4, which are respectively arranged on the left and right sides of the bottom of the trough. The blanking port 4 is in the shape of an inverted trapezoidal table. One side of the blanking port 4 is connected to the end of the blanking slope 3, and the other side is connected to the left side wall or the right side wall of the trough 1. The lower part of the blanking slope of the blanking slope 3 is matched with the discharge port 4.

[0028] There are two assembly grooves 5, which are respectively arranged on the outer sides of the upper parts of the left and right side walls. The size and position of the assembly groove 5 meet the assembly requirements for installing the device of the present invention on the coating machine.

[0029] As Figure 3 shown, before the plate is coated, the trough 1 is installed under the rubberized wheel 9 of the coating machine through the assembly groove 5. When the plate is coated, the lead paste after the paste mixing is completed enters the coating machine through the paste inlet 8, and the grid belt 6 and the coating paper 7 also enter the coating machine. Inside the coating machine, the coating machine coats the lead paste on the grid belt 6, and then coats the coating paper 7 on the lead paste and the grid belt 6. The coating paper 7 wraps the front and back sides of the plate belt 11 to form the plate belt 11. After the plate belt 11 comes out of the coating machine, it passes through the rubberized wheel 9, and the coating paper 7, the lead paste, and the grid belt 6 are pressed together. The excess lead paste is extruded and adhered to the rubberized wheel 9. The adhered remaining paste is cleaned up when passing through the paste scraping strip 10 and falls on the blanking slope 3 in the trough 1. At this time, the lead paste slowly drops under the action of its own gravity. When the new remaining paste drops, due to the increased gravity, the falling speed will also be accelerated. The falling lead paste drops through the discharge port 4 and falls into the remaining paste collection box 12. The remaining paste slowly accumulates, and the remaining paste will be blocked by the baffle 2 and fall on the blanking slope 3, and will not fall onto the surface of the plate. When the lead paste accumulates too much, it needs to be manually cleaned by the worker to ensure the normal operation of the device.
