Description

Technical Field

[0001] This utility model relates to a battery electrode scraping device. Background Technology

[0002] In the preparation of positive and negative electrode sheets for batteries, to improve production efficiency and reduce costs, relatively wide positive and negative electrode substrates, such as steel strips, are generally used for coating. The coated large electrode plates are then cut into multiple electrode sheets according to process requirements. However, some processes require white edges on the electrode sheets. To meet this requirement, there are generally two methods: one is to apply adhesive tape to the corresponding white edge area of ​​the substrate before coating, then remove the tape, and finally cut the sheet into electrode sheets; the other is to use ultrasonic cleaning to remove the slurry from the corresponding white edge area after the coated electrode sheets are dried. However, both methods are relatively complex, result in significant raw material waste, environmental pollution, and poor product width consistency. Utility Model Content

[0003] The present invention aims to provide a battery plate scraping device that is simple in structure, easy to use, and can quickly scrape the slurry.

[0004] This utility model is achieved through the following solution:

[0005] A battery plate scraping device includes two clamping plates. Several adjustable sliders are mounted on the top of the clamping plates and can slide on the top of the clamping plates. Scraping rubber is connected to the front side of each adjusting slider, slightly extending beyond the front side of the clamping plate. An adjusting bolt is connected to the rear side of each adjusting slider. The adjusting bolt is mounted on a bolt fixing block and can be adjusted back and forth on the bolt fixing block. The bolt fixing block is fixed to the top of the clamping plates. The two clamping plates are mounted on a fixed support platform with the scraping rubber facing each other and a certain distance between them. The number and position of the adjusting sliders can be designed and adjusted according to the scraping position and number of plates to be scraped. The scraping rubber extends beyond the front side of the clamping plates to ensure that the scraped material can be scraped cleanly from the plates. The distance between the two clamping plates can be adjusted appropriately according to the thickness of the plates to be scraped to ensure that the plates can pass through smoothly.

[0006] Furthermore, a comb tooth is nested on the front side of one of the clamps, the comb tooth being located below the scraper rubber and the scraper rubber slightly extending beyond the front side of the comb tooth.

[0007] Furthermore, the comb teeth include a substrate, and the front side of the substrate is provided with a plurality of vertically arranged and outwardly protruding through slots. The number, size, and position of the through slots can be adjusted and designed as needed to facilitate the flow of slurry scraped off by the scraper rubber down the through slots of the comb teeth into the slurry hopper. The arrangement of the comb teeth also avoids the problem of the scraper plate being biased to one side.

[0008] Furthermore, the front side of the clamp is provided with a stop block at each end of the comb teeth, and the stop block abuts against the corresponding end of the comb teeth.

[0009] Furthermore, protective covers are mounted on both ends of the top of the clamping plate, and these protective covers are positioned above the scraper rubber. The protective covers protect the scraper rubber, preventing debris and dust from falling onto it, which could lead to poor scraping and affect the quality of the electrode plate.

[0010] This utility model discloses a battery plate scraping device with a simple structure and convenient use. The adjusting bolts can effectively adjust the position and pressure of the scraping rubber. Through the cooperation of the adjusting bolts, adjusting sliders, and scraping rubber, the scraping material on the plate to be scraped can be effectively and quickly scraped clean. The scraped material can be reused for coating, reducing raw material waste and thus lowering the cost of electrode production. This utility model's battery plate scraping device is easy to maintain; when the scraping rubber or comb teeth become old or damaged, they can be replaced with new ones. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the comb teeth in Example 1. Detailed Implementation

[0013] The embodiments are merely illustrative of one implementation of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] In this invention, the side of the clamp plate facing the scraper plate is defined as the front side of the clamp plate, and correspondingly, the side of the adjusting slider and comb teeth that faces the same direction as the front side of the clamp plate is defined as the front side of the adjusting slider and comb teeth.

[0015] Example 1

[0016] A battery plate scraping device, such as Figure 1As shown, the device includes two clamping plates 1. Several adjusting sliders 2 are mounted on the top of the clamping plates 1, and these sliders 2 can slide on the top of the clamping plates 1. A scraper rubber 3 is connected to the front side of each adjusting slider 2, slightly extending beyond the front side of the clamping plates 1. Adjusting bolts 4 are connected to the rear side of each adjusting slider 2, and the adjusting bolts 4 are mounted on bolt fixing blocks 5, allowing them to move back and forth on the bolt fixing blocks 5. The bolt fixing blocks 5 are fixed to the top of the clamping plates 1. Protective cover plates 6 are mounted across both ends of the top of the clamping plates 1, and the protective cover plates 6 are positioned above the scraper rubber 3. A comb tooth 7 is nested on the front side of one of the clamping plates 1, such as... Figure 2 As shown, the comb tooth 7 includes a base plate 71. Several vertically arranged and outwardly protruding through slots 72 are provided on the front side of the base plate 71. The comb tooth 7 is located below the scraper rubber 3 and the scraper rubber 3 slightly extends beyond the front side of the comb tooth 7. The front side of the clamping plate 1 is provided with a stop block 8 at both ends of the comb tooth 7. The stop block 8 abuts against the corresponding end of the comb tooth 7. The two clamping plates 1 are mounted on the fixed support table in a way that the scraper rubber 3 is opposite each other and the two clamping plates 1 are spaced a certain distance apart (the fixed support is not shown in the figure).

[0017] In use, pass the electrode plate to be scraped through the gap between the two clamps of the battery electrode plate scraping device, and adjust the position of the electrode plate to be scraped so that each scraping point of the electrode plate is aligned with each scraping rubber of the two clamps. Then, ensure that the clamp without comb teeth is fixed and adjust the position of the scraping rubber by adjusting the bolts so that each scraping rubber is aligned with each scraping point of the electrode plate. Next, move the clamp with comb teeth closer to the electrode plate to be scraped, and adjust the position of the scraping rubber by adjusting the bolts so that each scraping rubber is aligned with each scraping point of the electrode plate. At this point, fix the clamp with comb teeth. This completes the fixed installation of the battery electrode plate scraping device, and the scraping work can then begin. The slurry scraped off by the scraping rubber flows down the through grooves of the comb teeth into the slurry hopper until all the slurry at each scraping point of the electrode plate is scraped off.
