DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figures 1 to 5 A small inductance casting machine, characterized in that it comprises a reeling unit 1, which is provided with a reeling shaft 11 and a casting structure 12, wherein a film roll is provided on the reeling shaft 11,

[0026] The casting structure 12 includes a coating roller, a material trough 122 and a scraper 123 located outside the coating roller. The film rolled out from the film passes through the casting structure 12 and the slurry in the material trough 122 is attached to the surface.

[0027] The oven unit 2 comprises a plurality of ovens arranged in parallel, wherein the ovens are provided with a drying channel for drying the film with the slurry;

[0028] The winding unit 3 includes a winding roller 31 for collecting the dried film.

[0029] The film is loaded and the ceramic slurry is loaded and cast at the casting structure 12, and then dried by the oven unit 2, and then wound up by the winding unit 3, thereby realizing the automated production process of cast coating. At this time, the ceramic slurry can be cast evenly through the action of the coating roller, the material trough 122, and the scraper 123, which can meet the requirements of different casting thicknesses.

[0030] At the same time, multiple ovens arranged in parallel can effectively dry the ceramic slurry during use. The longer drying channel design can achieve slow drying and better adhesion effect after drying. At this time, each oven is controlled separately to achieve different drying temperatures.

[0031] At this time, since the material tank 122 is filled with ceramic slurry and contacts the membrane passing through the material tank 122, the ceramic slurry in the material tank 122 is in a consumption state. Therefore, in order to avoid too little ceramic slurry in the material tank 122 affecting the coating process, it is necessary to detect the amount of ceramic slurry in the material tank 122. In this embodiment, the material tank 122 is provided with a liquid level sensor for detecting the liquid level height of the slurry in the material tank 122. At this time, the ceramic slurry is liquid, so the remaining amount of ceramic slurry in the material tank 122 can be well detected by the liquid level sensor.

[0032] Furthermore, in order to realize automatic addition of ceramic slurry into the material trough 122 , in the present embodiment, the material trough 122 is provided with a feed pipe, and the feed pipe is connected to a material tank through a solenoid valve. Of course, a pump is also provided at this time to pump the ceramic slurry in the material tank into the material trough 122 .

[0033] During the casting process, more ceramic slurry will adhere to the outside of the film, so the excess ceramic slurry needs to be scraped off by a scraper 123. In the present embodiment, the scraper 123 is an annular tool, which is fixed by a fixed shaft. The outer annular surface of the scraper 123 is provided with a fixed table, and the fixed table and the annular surface of the scraper 123 form a scraper 123 surface. The scraper 123 is located on the fixed table and fixed to the fixed shaft. The scraper 123 surface is close to the outer side surface of the coating roller, and the film passes between the scraper 123 surface and the coating roller. At this time, the casting structure 12 includes a side plate, a coating roller 121 is rotatably set on one side of the side plate, and a fixed shaft is fixedly set on the same side of the side plate. The scraper 123 is fixed on the outside of the fixed shaft, so that the scraper 123 and the coating roller are spaced apart. In order to scrape off excess ceramic slurry on the surface of the film, the scraper 123 is set at the outer position of the coating roller, and the film passes between the scraper 123 and the coating roller. At this time, a certain distance is set between the scraper 123 and the coating roller. At the same time, the position of the scraper 123 can be adjusted, so that during the casting process, the position of the scraper 123 can be adjusted according to the required casting thickness, thereby achieving different casting thicknesses.

[0034] After the ceramic slurry is cast and dried, it needs to be rolled up. At this time, the edge position of the film may have a poor casting effect due to the softness of the film. Therefore, the two sides of the film need to be cut off before the film is rolled up. In this embodiment, the rolling unit 3 also includes a trimming structure 32, and the trimming structure 32 includes a cutter fixing plate 321. The side of the cutter fixing plate 321 is provided with a guide rail, and the side of the guide rail is connected to a cutter movable seat 322 through a slider. A cutting blade 323 is provided on the outer side of the cutter movable seat 322. At this time, the cutter fixing plate 321 is fixed to the side of the side plate of the rolling unit 3, and the cutting blade 323 is used to trim the film passing through this position, so that the middle position of the film is rolled up and the side position is cut off.

[0035] Furthermore, in order to facilitate the adjustment of the cutting width during the cutting process, in the present embodiment, two cutter movable seats 322 are provided, and the side of the cutter movable seat 322 is provided with a fixing seat for fixing the cutter movable seat 322 to the outside of the guide rail, and the fixing seat is provided with a fixing nut 324, and the fixing nut 324 abuts against the guide rail when tightened. By adjusting the tightness of the fixing nut 324, the cutter movable seat 322 can be fixed to the outside of the guide rail. When it needs to be moved, the fixing nut 324 is loosened and the cutter movable seat 322 is moved on the guide rail, thereby realizing the adjustment of the cutting width. Furthermore, in order to be able to determine the size of the cutting, a scale is provided on the side of the guide rail or the cutter fixing plate 321, which is convenient for observing the distance between the two cutters, thereby ensuring that the obtained film meets the production requirements.

[0036] During the production process, dust may be adsorbed on the surface of the film, and the dust needs to be removed to ensure the quality of the film winding. In this embodiment, the winding unit 3 also includes a dust suction structure 33, which includes a dust suction shaft 331. The dust suction shaft 331 is provided with two dust suction shafts 331, which are arranged in parallel. The dried film passes through the gap between the two dust suction shafts 331. The dust suction shaft 331 is provided with a dust suction groove 332 on the side facing the film. The interior of the dust suction shaft 331 is a hollow hole connected to the dust suction groove 332. The hollow hole is connected to a vacuum motor for forming a negative pressure at the position of the dust suction groove 332. The vacuum motor generates a vacuum, so that the dust suction shaft 331 forms a negative pressure at the position of the dust suction groove 332. When the film passes between the two dust suction shafts 331, the dust and other impurities on the surface of the film can be adsorbed, thereby completing the cleaning of the film surface. At this time, the dust suction structure 33 is arranged in the post-process of the trimming structure 32, and the tiny film fragments generated during the cutting process can also be adsorbed and cleaned.

[0037] After the film is cast, it needs to be dried before it can be rolled up. Therefore, in this embodiment, the oven unit 2 includes a plurality of ovens arranged, and the oven includes an upper air duct and a lower air duct, and the upper air duct and the lower air duct are arranged at intervals to form a drying channel. At this time, the oven unit 2 is mainly used for drying, and adopts the technical solution in the prior art or the technical solution originally applied for a patent by the company, so it is not described in detail here.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
