Description

Technical Field

[0001] The utility model belongs to the technical field of diaphragm coating, and in particular relates to a scraping device for diaphragm coating. Background Art

[0002] Diaphragm coating technology is a crucial technology in modern industry, especially in battery manufacturing, chemical separation and other industries that require precise coating. Diaphragm is a key component in these applications, and the quality of its coating is directly related to the performance and stability of the product.

[0003] In order to improve the uniformity of diaphragm coating, a scraping device has been developed. For example, in a Chinese patent with publication number "CN148394487U", a scraping device for diaphragm coating is disclosed. When the device is used, the fixed rod is pressed and the entire scraping device is pushed by the driving wheel to push the paint for scraping by the driving roller. When the user uses the scraping device, the paint adhering to the driving roller can be dried by the heater and the dry paint adhering to the driving roller can be removed by the scraper blade. At the same time, the slag block can be set to prevent the dry paint slag from detaching, thereby solving the problem of some dry paint remaining on the scraping mechanism of the existing scraping device to a certain extent. When the device is applied to the diaphragm, in order to avoid uneven coating caused by residual paint on the device, a structure for cleaning the paint on the device is set. However, when the device needs to be cleaned, the personnel need to stop the device for cleaning, and it cannot be cleaned while coating. Not only is the cleaning difficult, but the cleaning efficiency is also low. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions: a scraping device for diaphragm coating, comprising an input member and an output member, a conveying channel for conveying the diaphragm along a preset path is formed between the input member and the output member, a scraping member for scraping the diaphragm is arranged between the conveying channels, the scraping member comprises a roller 6 rotating along a horizontal axis, at least two scrapers 8 are fixedly connected to the circumferential surface of the roller 6, and the scraping member also comprises a cleaning portion for scraping the scraper 8.

[0028] Through the above technical scheme, when one end of the coated diaphragm is placed between the input part, the scraper part and the output part in sequence, the output part and the input part work to guide the diaphragm to move relative to the scraper part. When the coated diaphragm moves, the scraper part scrapes the diaphragm flat, and then smoothes the paint on the diaphragm to make excess paint on the diaphragm fall off. Since at least two scrapers 8 are provided, one of the scrapers 8 is used to scrape the excess paint on the diaphragm. When personnel need to clean the scraper 8, the scraper 8 is driven to rotate by the roller 6, and then the current scraper 8 is rotated to other positions, so that the unused scraper 8 contacts the diaphragm, and the used scraper 8 is cleaned by the cleaning part, so that the scraper 8 can scrape the paint on the diaphragm more evenly, and the cleaning can be performed simultaneously when the diaphragm is scraped flat, without stopping the machine for cleaning.

[0029] In addition, in the utility model, the scraping device also includes a liquid storage member, which is arranged below the scraper 8, and the top of the liquid storage member is recessed to form a liquid storage space for storing paint, and the input member and the output member are both installed on the liquid storage member.

[0030] In this embodiment, when the scraper 8 scrapes off the excess paint on the diaphragm, the excess paint is collected by the liquid storage space on the liquid storage member, which is convenient for the subsequent treatment of the paint.

[0033] In this embodiment, the roller 6 is supported by two side plates 13. When personnel need to adjust the position of the roller 6, the second motor 19 is operated to drive the roller 6 to rotate relative to the side plate 13, and then the roller 6 drives the scraper 8 to rotate, thereby adjusting the position of the scraper 8.

[0034] Specifically, in one embodiment, regarding the above-mentioned cleaning part:

[0035] like Figure 1-Figure 5 As shown, the cleaning part includes a moving frame 17, the bottom of the moving frame 17 is sunken to form a groove matching the scraper 8, a rubber plate 16 is bonded inside the groove, the tops of the two side plates 13 are fixedly connected to the second electric push rod 9, the telescopic end of the second electric push rod 9 is fixedly connected to the top plate 7, a screw rod 18 is fixedly connected between the two top plates 7, and the top of the moving frame 17 is sleeved on the screw rod 18;

[0036] A first motor 12 is fixedly connected to one of the top plates 7 , and an output end of the first motor 12 is connected to a lead screw 18 .

[0037] In this embodiment, when the scraper 8 is away from the diaphragm after use, the second electric push rod 9 is operated, and then the second electric push rod 9 drives the top plate 7 to move, and then drives the moving frame 17 to contact the scraper 8 after use, and the first motor 12 is operated, and then the first motor 12 drives the screw rod 18 to rotate, so that the moving frame 17 and the rubber plate 16 scrape the scraper 8, and then the scraper 8 is cleaned, so that the paint attached to the scraper 8 falls off.

[0038] Specifically, in one embodiment, regarding the above-mentioned liquid storage component:

[0039] like Figure 1-Figure 5 As shown, the liquid storage element includes a liquid storage box 1, and the top of the liquid storage box 1 is opened to form a liquid storage cavity 15.

[0040] In this embodiment, when the paint falls off the scraper 8, the paint is collected by the liquid storage chamber 15 on the liquid storage box 1, so that personnel can easily handle the paint later.

[0041] In addition, in the present invention, how the input member and the output member guide the diaphragm to move, such as Figure 1 , Figure 3-Figure 5 As shown, the input member includes a first mounting frame 2, which is fixed to one side of the liquid storage tank 1, and the first mounting frame 2 is internally symmetrically rotatably connected to two input rollers 3 for guiding the diaphragm to be input to the bottom of the scraper 8;

[0043] In this embodiment, the diaphragm to be smoothed is transported between two input rollers 3, and then the diaphragm is transported between two output rollers 10 after passing under the scraper 8. The input roller 3 is supported by the first mounting frame 2, and the output roller 10 is supported by the second mounting frame 11. The input roller 3 and the output roller 10 are rotated to drive the diaphragm to move.

[0044] In order to adjust the distance between the scraper 8 and the diaphragm, and then adjust the coating thickness of the coating on the diaphragm, such as Figure 1-Figure 5 As shown, first electric push rods 5 are fixedly connected to both symmetrical sides of the liquid storage tank 1 , and telescopic ends of the two first electric push rods 5 are connected to the side plates 13 .

[0045] In this embodiment, when personnel need to adjust the coating thickness on the diaphragm, the first electric push rod 5 is operated, and then the first electric push rod 5 drives the side plate 13 to move, and the side plate 13 drives the roller 6 and the scraper 8 to move, and then the distance between the scraper 8 and the diaphragm is adjusted, thereby achieving the purpose of adjusting the coating thickness on the diaphragm.
