Description

Technical Field

[0001] This utility model belongs to the technical field of glazing equipment, specifically relating to a bell jar height adjustment device. Background Technology

[0002] In the process of tile production, a glazing machine is used to apply a layer of glaze to the surface of the tile. The glaze flows down from the glaze bucket set on the upper side of the bell jar. The glaze on the bell jar continues to flow down from the edge of the bell jar to form a glaze waterfall. After the tile body passes through the glaze waterfall, a layer of glaze is applied to the surface of the body. Then, after processes such as sintering, a glaze layer is formed on the surface of the tile.

[0003] The bell jar is fixed between bell jar columns by brackets. During the installation and debugging of the bell jar, it is necessary to adjust its height and level. Chinese utility model patent application number 202222333910.4 discloses a bell jar height adjustment device, including a height adjustment plate and a lifting adjustment mechanism. The height adjustment plate is located on the lower side of the bell jar bracket and is connected to the bell jar column through an adjustment connecting component. The lifting adjustment mechanism is located between the height adjustment plate and the bell jar bracket, with its upper end abutting against the lower side of the bell jar bracket. Using the height adjustment plate as a support plate, the lifting adjustment mechanism raises the bell jar bracket, thereby adjusting the height or level of the bell jar. However, its application has the following problems: the height of the bell jar can be easily increased using jacks, but when lowering the height of the bell jar, it is difficult to lower it using its own weight. Furthermore, the four height adjustment devices of the bell jar cannot be lowered synchronously, causing the bell jar to not be level, making it difficult to lower. Lowering the bell jar requires workers to use tools to hammer it down, which is very inconvenient. Utility Model Content

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] like Figure 1 As shown, the present invention provides a bell jar height adjustment device, comprising a bell jar 1, a bracket 3, and a support column 2. The bell jar 1 is fixedly connected to the bracket 3. Four brackets 3 are evenly distributed around the bell jar 1. The four brackets 3 are all vertically connected to the four support columns 2 via an adjustment component 4. The height of the bell jar 1 is adjusted by the adjustment component 4 moving up and down along the support columns 2. An adjustment rack 5 is vertically arranged on the support columns 2. The adjustment component 4 includes an adjustment gear that meshes with the adjustment rack 5. The adjustment gear is connected to a rotary drive component. The adjustment gear moves up or down along the adjustment rack 5. The height of the bell jar 1 is adjusted by the transmission of the gear and rack. A locking component 9 is also provided on one side of the adjustment component 4. The locking component 9 fixes the adjustment component 4 so that it no longer moves up or down along the adjustment rack 5. A funnel for storing glaze is set above the bell jar 1. The funnel is fixed by other columns. The glaze flows down through a stopcock valve on the lower side of the funnel. The glaze flows down evenly from the edge of the bell jar 1 to form a glaze waterfall, and a layer of glaze is applied to the surface of the ceramic tile.

[0022] like Figures 2-3 As shown, the adjustment assembly 4 also includes an adjustment housing 7. The adjustment housing 7 has a circular channel in the middle. The adjustment housing 7 is fitted outside the support column 2. One side of the adjustment housing 7 is fixedly connected to the bracket 3. The adjustment gear is rotatably installed inside the adjustment housing 7. The rotation drive is an adjustment handle 8. The adjustment handle 8 is connected to the adjustment gear. The adjustment handle 8 is rotatably connected to the outside of the adjustment housing 7. Rotating the adjustment handle 8 causes the adjustment gear to rotate. When the adjustment gear rotates, it will rise or fall along the adjustment rack 5, thereby causing the bracket 3 and the bell jar 1 to rise or fall together.

[0023] like Figure 4As shown, in this embodiment, the adjusting handle 8 is connected to the adjusting worm 10, and the adjusting gear is the adjusting worm wheel 11. The adjusting worm wheel 11 meshes with the adjusting worm 10, and at the same time, the adjusting worm wheel 11 also meshes with the adjusting rack 5. The adjusting worm 10 and the adjusting worm wheel 11 are both set inside the adjusting housing 7. The adjusting worm 10 is set perpendicular to the tooth surface of the adjusting rack 5. The adjusting handle 8 is connected to one end of the adjusting worm 10. When the adjusting handle 8 is rotated, the adjusting worm 10 rotates, and the adjusting worm wheel 11 rotates synchronously. At the same time, since the adjusting worm wheel 11 meshes with the adjusting rack 5, the adjusting worm wheel 11 will rise and fall along the adjusting rack 5 while rotating.

[0024] In this embodiment, a locking groove 12 is vertically formed on one side of the adjusting housing 7, and a locking component 9 is provided between the two sides of the locking groove 12. Specifically, locking blocks 13 are provided protruding outward on both sides of the locking groove 12, and the locking component 9 is threadedly connected to the two locking blocks 13. One end of the locking component 9 is rotatably connected to a locking handle 14. By rotating the locking component 9 through the locking handle 14, the locking component 9 is pulled closer to the two sides of the locking groove 12, so that the adjusting housing 7 hugs the supporting column 2, fixing the adjusting component 4 and preventing it from rising or falling. When the locking component 9 is opened, the adjusting housing 7 no longer hugs the supporting column 2, allowing the adjusting component 4 to rise and fall along the supporting column 2. In other embodiments, the locking component 9 can also be a locking bolt and a locking nut, where tightening the locking nut makes the adjusting housing 7 hug the supporting column 2.

[0025] The support column 2 has a mounting groove on its side, and one side of the adjusting rack 5 is embedded in the mounting groove. Both ends of the adjusting rack 5 are fixed to the support column 2 by fixing rings 15. The fixing rings 15 also limit the upward or downward movement of the adjusting component 4 to prevent the adjusting component 4 from disengaging from the adjusting rack 5.

[0026] In use, the four adjusting components 4 around the bell jar 1 are adjusted sequentially. First, the locking handle 14 is opened, and the adjusting handle 8 is cranked by hand. The adjusting worm gear 10 rotates, and the adjusting worm wheel 11 rotates synchronously. Simultaneously, since the adjusting worm wheel 11 meshes with the adjusting rack 5, it rises or falls along the adjusting rack 5 as it rotates. When the appropriate height is reached, the two locking blocks 13 are locked using the locking handle 14 and the locking component 9. Then, the height of the other adjusting components is adjusted. This process is repeated sequentially to adjust the height of all adjusting components 4, ultimately achieving the overall height adjustment of the bell jar 1. This invention features a simple structure and convenient adjustment. It utilizes gear and rack transmission to adjust the height of the bell jar 1, allowing direct rotation of the gears to raise or lower the bell jar 1. Both raising and lowering of the bell jar 1 can be adjusted quickly.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
