Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and more specifically, to a coating equipment for insulating layers on silicon steel surfaces. Background Technology

[0002] In the continuous annealing process of grain-oriented silicon steel, a magnesium oxide coating needs to be applied and the steel dried and coiled. The physicochemical properties of the magnesium oxide coating play a decisive role in the surface quality of the finished grain-oriented silicon steel product. In the production process of non-oriented silicon steel, the quality of the coating has a significant impact on the product's insulation, rust prevention, and processing performance. The traditional spraying method involves setting spray pipes on both the upper and lower sides of the strip in the transport direction. The nozzles on the spray pipes on both sides can coat the upper and lower surfaces simultaneously. However, if the production speed is high, the spray pipe pressure fluctuates, or a low-viscosity coating liquid is used, the coating liquid on the strip surface cannot be evenly distributed, resulting in coating streaks and, in severe cases, incomplete coating, affecting product quality.

[0003] For example, a silicon steel coating spraying device disclosed in Chinese invention patent / utility model patent (application number: CN222000438U) includes a frame, a coating assembly and a scraping assembly. Two sets of the coating assemblies are rotatably connected to the left and right sides of the frame at intervals. One set of the coating assemblies is slidably connected to the lead screw assembly through a sliding block, and the other set of the coating assemblies is fixedly connected to the two sides of the bottom of the frame and located in the storage box.

[0004] Although the aforementioned patents can enhance the quality of silicon steel sheets in the coating process, the aforementioned device still has the following problems: During the use of the device, because the scraping component of the device is fixed in position when scraping off excess coating on the steel strip, the device cannot float to a certain extent. When the plate becomes curved, the device cannot follow the plate to a certain extent, thus failing to guarantee the consistency and uniformity of the coating thickness.

[0005] Therefore, we have made improvements to this and proposed a silicon steel surface insulation coating equipment. Utility Model Content

[0006] The purpose of this invention is to solve the problem that when the device scrapes off excess coating on the steel strip, the scraping component is fixed in position, preventing the device from floating and causing the device to be unable to move with the plate when the plate is curved.

[0007] In order to achieve the above-mentioned utility model objectives and improve the above-mentioned problems, this utility model provides a silicon steel surface insulation layer coating device, including a device body, a cylinder fixedly connected to the top and bottom of the device body, a support plate fixedly connected to the output end of the two cylinders, a mounting bracket provided on the adjacent side of the two support plates, a sliding groove provided inside the two mounting brackets, a floating block slidably connected inside the two sliding grooves, a rotating groove provided inside the floating block, and an adjusting scraping device provided inside the rotating groove.

[0008] The adjusting scraping device includes a rotating plate, the surface of which is rotatably connected to the inside of the rotating groove. A base is fixedly connected to one side of the rotating plate, and a scraper is fixedly connected to the side of the base away from the rotating plate. A rotating shaft is fixedly connected to one side of the rotating plate, and the end of the rotating shaft away from the rotating plate rotates through the inside of the rotating groove and extends to the outside of the floating block. The rotating plate is rotatably connected to the inside of the rotating groove through the rotating shaft.

[0009] As a preferred technical solution of this application, the support plate has a positioning groove on the side near the mounting bracket, and the mounting bracket is therefore fixedly connected to a positioning block near the support plate.

[0010] As a preferred technical solution of this application, both the positioning groove and the positioning block have trapezoidal cross sections, the surface of the positioning block is slidably connected to the interior of the positioning groove, and the positioning block is fixedly mounted on the support plate by bolts.

[0011] As a preferred technical solution of this application, a limiting rod is fixedly connected inside the slide groove, a limiting groove is opened inside the floating block, and the surface of the limiting rod is slidably connected to the inside of the limiting groove.

[0012] As a preferred technical solution of this application, a spring is fixedly connected to the inner wall of the slide, and the end of the spring near the floating block is fixedly connected to the surface of the floating block.

[0013] As a preferred technical solution of this application, a rotating groove is provided on one side of the floating block, and a rotating disk is rotatably connected inside the rotating groove. The inside of the rotating disk is fixedly connected to the surface of the rotating shaft, and a handle is fixedly connected to one side of the rotating disk. The handle is located at a point away from the center of the rotating disk.

[0014] As a preferred technical solution of this application, the device body is provided with a collection box inside, and a guide plate is fixedly connected to the top of the lower floating block.

[0015] As a preferred technical solution of this application, a guide groove is provided on the top of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. By setting up springs, floating blocks, and scrapers, the force of the springs on the floating blocks is realized, allowing the floating blocks and scrapers to float to a certain extent. The floating design ensures the consistency and uniformity of coating thickness within a wide range of the scraper and when facing plate shape fluctuations, reducing the risk of scratches, improving the product qualification rate, and making it easier for workers to use the device.

[0019] 2. By using a rotating disc and handle, the rotating disc enables the rotating shaft to rotate more smoothly, and the rotating shaft drives the rotating plate to rotate. The rotating plate can adjust the angle of the scraper, allowing the scraper to fit more closely to the surface of the steel strip. This makes the device more efficient at scraping off the insulation layer, making the insulation coating process of the steel strip more convenient. Attached Figure Description

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A silicon steel surface insulation layer coating equipment includes a main body 1, which is an existing structure and will not be described in detail here. The main body 1 can coat the silicon steel surface through rollers. The top and bottom of the main body 1 are fixedly connected to cylinders 2, which are existing structures and will not be described in detail here. The two cylinders 2 are equipped with the same structure. The output ends of the two cylinders 2 are fixedly connected to support plates 3. The adjacent sides of the two support plates 3 are provided with mounting brackets 4. The interior of the two mounting brackets 4 is provided with sliding grooves 17. The interior of the two sliding grooves 17 is slidably connected to floating blocks 5. The interior of the floating blocks 5 is provided with rotating grooves 6. The interior of the rotating grooves 6 is provided with an adjusting scraping device.

[0033] The adjusting scraping device includes a rotating plate 7, the surface of which is rotatably connected to the interior of the rotating groove 6. A base 8 is fixedly connected to one side of the rotating plate 7, and a scraper 9 is fixedly connected to the side of the base 8 away from the rotating plate 7. The device can scrape off the insulating layer coated on the surface of the silicon steel strip through the scraper 9. A rotating shaft 11 is fixedly connected to one side of the rotating plate 7. The end of the rotating shaft 11 away from the rotating plate 7 rotates through the interior of the rotating groove 6 and extends to the exterior of the floating block 5. The rotating plate 7 is rotatably connected to the interior of the rotating groove 6 through the rotating shaft 11.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a positioning groove 15 is provided on the side of the support plate 3 near the mounting bracket 4. A positioning block 16 is fixedly connected to the mounting bracket 4 near the support plate 3. The cross-sections of the positioning groove 15 and the positioning block 16 are both trapezoidal. The surface of the positioning block 16 is slidably connected to the interior of the positioning groove 15. The positioning block 16 is fixedly installed on the support plate 3 by bolts. The fact that the cross-sections of the positioning groove 15 and the positioning block 16 are both trapezoidal makes the position of the mounting bracket 4 so that the mounting bracket 4 can be installed and fixed more smoothly.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a limiting rod 18 is fixedly connected inside the slide groove 17, and a limiting groove 19 is opened inside the floating block 5. The surface of the limiting rod 18 is slidably connected to the inside of the limiting groove 19. Through the mutual cooperation of the limiting rod 18 and the limiting groove 19, the movement direction of the floating block 5 can be restricted, and the floating block 5 can move up and down more smoothly.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a spring 20 is fixedly connected to the inner wall of the slide 17. The end of the spring 20 near the floating block 5 is fixedly connected to the surface of the floating block 5. The spring 20 can be compressed and reset by the movement of the floating block 5.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a rotating groove 12 is provided on one side of the floating block 5. A rotating disk 13 is rotatably connected inside the rotating groove 12. The inside of the rotating disk 13 is fixedly connected to the surface of the rotating shaft 11. The rotating disk 13 enables the rotating shaft 11 to rotate more smoothly and drives the rotating plate 7 to rotate. The rotating plate 7 can adjust the angle of the scraper 9, so that the scraper 9 can fit more closely to the surface of the steel strip. This allows the device to scrape off the insulation layer more smoothly, making the coating process of the insulation layer of the steel strip more convenient. A handle 14 is fixedly connected to one side of the rotating disk 13. The handle 14 is located away from the center of the rotating disk 13. The handle 14 allows the operator to drive the rotating disk 13 to rotate more smoothly. The rotating disk 13 is fixedly installed on the floating block 5 by bolts. After the operator adjusts the angle of the scraper 9 and fixes the position of the rotating disk 13 with bolts, the position of the scraper 9 can be fixed.

[0038] Example 2

[0039] The silicon steel surface insulation layer coating equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the equipment body 1 is equipped with a collection box 21 inside, which can collect excess paint. The top of the lower floating block 5 is fixedly connected to a guide plate 22, which is set at the bottom of the base 8. The guide plate 22 can guide the paint scraped by the scraper 9 and make the paint more smoothly collected. The paint inside the collection box 21 is extracted by the pump on the collection box 21.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a guide groove 10 is provided on the top of the base 8. The guide groove 10 can guide the scraped paint and make the paint flow more smoothly into the interior of the guide plate 22.

[0041] The process of using the silicon steel surface insulation coating equipment provided by this utility model is as follows: The operator drives the handle 14 to rotate the rotating disk 13. The rotating disk 13 enables the rotating shaft 11 to rotate more smoothly, and the rotating shaft 11 drives the rotating plate 7 to rotate. The rotating plate 7 can adjust the angle of the scraper 9, so that the scraper 9 can fit more closely to the surface of the steel strip, thereby enabling the device to scrape the insulation layer more smoothly and making the insulation coating process of the steel strip more convenient. After the scraper 9 is adjusted to the appropriate position, the bolt is used to fix the position of the rotating disk 13, so that the position of the scraper 9 can be fixed.

[0042] After the worker feeds the steel strip into the equipment body 1, the equipment body 1 is started. The equipment body 1 can coat the silicon steel surface through the roller. At the same time, the worker starts the cylinder 2 through the external control device. The cylinder 2 drives the support plate 3 to move up and down, and enables the device to scrape the steel strip. At the same time, the force of the spring 20 on the floating block 5 makes the floating block 5 and the scraper 9 float to a certain extent. The floating design ensures the consistency and uniformity of the coating thickness within a wide range of the scraper 9 and when facing plate shape fluctuations, reducing the risk of scratches, improving the product qualification rate, and making it more convenient for workers to use the device.

[0043] The guide plate 22 can guide the paint scraped by the scraper 9 and make the paint enter the collection box 21 more smoothly for centralized collection. At the same time, the pump on the collection box 21 can extract the paint inside the collection box 21.
