DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] The utility model provides a kind of tin scraping device of tin dipping machine, as shown in Figures 1 to 5 The utility model discloses a kind of tin scraping device of tin dipping machine, as shown in

[0026] The connecting arm 5 is in close contact with the abutting portion A2041. When the convex abutting block 204 at one end of the driving motor 7 starts to rotate, the connecting arm 5 will be in contact with the convex abutting block 204. At this time, the abutting portion A2041 at the highest point of the convex abutting block 204 starts to rotate clockwise around the shaft under the action of force because the front end is blocked by the connecting arm 5. With the progress of this process, the connecting arm 5 gradually moves downward under the influence of the rotating action of the abutting portion A2041. During this movement, the vertical angle of the convex abutting block 204 continuously changes, and the scraper 606 connected thereto gradually descends. Since the movement track of the connecting arm 5 is in the shape of an arc, the scraper 606 gradually descends along the arc track while moving upward. When the scraper 606 moves to the front end of the tin furnace, the scraper 606 is just at the lowest point. Conversely, when the abutting portion B2042 gradually approaches the connecting arm 5, the entire scraper 606 starts to move upward and finally rises to the highest point. In this way, the scraper 606 presents a curved movement track during the entire working process. This movement mode ensures that the tin scraping direction of the scraper 606 is consistent at all times, thereby ensuring more excellent tin scraping effect.

[0027] When the scraper 606 closely adheres to the surface of the tin dregs, the spring 205 is in a stretched deformed state and stores a certain elastic potential energy. Once the condition for releasing the tensile force of the spring 205 is triggered, the spring 205 will exert a pulling force on the bearing bottom plate 203 at one end due to its original restoring property. Under the action of the pulling force, the bearing bottom plate 203 drives the entire scraper 606 connected thereto to move smoothly and linearly in the horizontal direction, thereby effectively cleaning the tin dregs, ensuring the flatness and purity of the surface of the tin liquid, and ensuring the smoothness of the tin dipping operation and the reliability of the tin dipping quality.

[0028] The L-shaped vertical plate 3 is fixedly installed on the surface of the side plate component 1 close to the guide rail 201 through bolts. The upper surface of the L-shaped vertical plate 3 is fixedly installed with the recovery channel 4.

[0029] The flow guide groove 605 arranged between the scraper 606 and the limiting plate 603 can efficiently and accurately collect and guide the oxidized layer material scraped off from the surface of the tin liquid by the scraper 606. During the operation of the scraper 606, the scraped-off oxidized layer flows along the path of the flow guide groove 605. Since the flow guide groove 605 has a V-shaped slope, the gravity and the flow guide characteristics thereof can be fully utilized to make the oxidized layer flow smoothly into the bottom pre-provided recovery channel 4. Such a structure design not only effectively avoids the residue and accumulation of the oxidized layer in the tin dipping machine, prevents secondary pollution or interference on the subsequent tin dipping operation, but also provides a convenient condition for the centralized recovery and treatment of the oxidized layer, which is conducive to the recycling of resources and the protection of the environment.

[0030] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
