Description

Technical Field

[0001] The utility model relates to the technical field of ceramic production equipment, in particular to a glaze pouring device. Background Art

[0002] In the ceramic industry, most ceramic manufacturers use the bell-shaped glaze pouring process to glaze bricks. Since the bell-shaped glaze pouring device is arc-shaped, the glaze can apply pressure to various points of the brick more evenly through the arc-shaped cover, the difference in glazing weight is small, and the final glaze quality is higher.

[0003] In actual production, the part of the bell jar parallel to the glaze line is generally used for glazing production. When the tiles are glazed, the tiles pass from one side under the bell jar to the other side so that a glaze layer is formed on the tiles when they enter. During the entire glazing process, the bell jar only needs to form a glaze curtain on the side where the tiles enter, and the glaze curtain can be used to evenly apply glaze on the surface of the tiles.

[0004] In the existing bell jar glazing line, it is possible to use the existing glaze line for the research and development and testing of pilot products. In the pilot situation, some pilot products do not require the glazing process or only need a single line. If the production of the glaze line is stopped only for the research and development and testing of a few pilot products, on the one hand, there may be a risk of empty kilns, and on the other hand, the stop of the glaze line is likely to cause the precipitation of the glaze. Restarting the glaze line requires re-adjusting production parameters such as the specific gravity of the glaze, which wastes manpower and material resources. In addition, after stopping the glaze line, the glazed bell jar needs to be cleaned, which may also cause glaze quality defects and the risk of damaging the bell jar, reducing the rate of high-quality products.

[0005] Therefore, in the existing production process, if a product that needs to be tested in a pilot test passes through the bell jar on a normal production glaze line, the technicians need to hold the glaze blocking plate to block it, so as to prevent the glaze forming a curtain through the bell jar from dripping onto the surface of the pilot product. If the number of pilot products is large, the glaze blocking time will also be long, which is likely to cause excessive physical exertion of the technicians. Utility Model Content

Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

[0033] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0034] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated by specific implementation methods.

[0035] A glazing device, comprising a tile conveying line, a bell glazing assembly 2, a glaze blocking assembly 3 and a glaze collecting assembly 4, wherein the tile conveying line is used to convey tiles, the bell glazing assembly 2 is arranged above the tile conveying line, and the bell glazing assembly 2 is used to form a glaze curtain and glaze the tiles;

[0036] The glaze collecting assembly 4 is arranged below the tile conveying line and is located directly below the bell jar glazing assembly 2. The glaze collecting assembly 4 is used to collect the flowing glaze;

[0037] The glaze stop assembly 3 is arranged above the tile conveyor line and spans across both sides of the tile conveyor line. The glaze stop assembly 3 is detachably connected to the tile conveyor line and can be moved along the length direction of the tile conveyor line so that the glaze stop assembly 3 is located at or away from directly below the bell jar glaze pouring assembly 2. The glaze stop assembly 3 is used to block the glaze from flowing toward the tile conveyor line, and the glaze flows from both sides of the glaze stop assembly 3 to the glaze collecting assembly 4.

[0038] In the existing production process, if it is necessary to develop or test pilot products on a normal glaze pouring line, technicians need to hold a glaze blocking plate to block the glaze, so as to prevent the glaze forming a curtain through the bell jar from pouring onto the surface of the pilot products. If the number of pilot products is large, the glaze blocking time will also be long, which is likely to cause excessive physical exhaustion of the technicians.

[0039] In order to solve the above technical problems, the present technical solution proposes a glaze pouring device, such as Figure 1 As shown, it includes a tile conveyor line, a bell-shaped glaze pouring assembly 2, a glaze retaining assembly 3 and a glaze collecting assembly 4; the bell-shaped pouring assembly 2 is arranged above the tile conveyor line, the tile conveyor line is used to convey tiles 5, and the bell-shaped pouring assembly 2 is used to form a glaze curtain and pour glaze on the tiles 5.

[0040] Specifically, the glaze blocking assembly 3 is detachably arranged above the tile conveyor line, and can be moved along the length direction of the tile conveyor line, so that the glaze blocking assembly 3 can be moved to the position directly below the bell glaze pouring assembly 2 or away from the bell glaze pouring assembly 2. When the bell glaze pouring line is operating normally, the glaze blocking assembly 3 can be moved to a position away from the bell glaze pouring assembly 2 to avoid the glaze blocking assembly 3 blocking the normal pouring of the glaze. When the bell glaze pouring line needs to test the pilot product, the glaze blocking assembly 3 is moved to the bottom of the bell glaze pouring assembly 2, and the glaze is blocked by the glaze blocking assembly 3 to fall on the pilot product conveyed by the tile conveyor line. After the glaze is intercepted by the glaze blocking assembly 3, it flows from both sides of the glaze blocking assembly 3 to the glaze collecting assembly 4 located below. Since the glaze blocking assembly 3 spans both sides of the tile conveyor line, the glaze flows from both sides of the glaze blocking assembly 3 to the glaze collecting assembly 4 without affecting the pilot product conveyed by the tile conveyor line.

[0041] The addition of the glaze retaining assembly 3 in the present scheme is beneficial to intercepting the glaze poured through the bell jar and diverting it to the glaze collecting assembly 4 below through both sides when the bell jar glazing line does not need glazing, thereby saving manpower and reducing the manpower cost in the process of pilot product testing; at the same time, the glaze retaining assembly 3 moves as a whole in the space between the tile conveyor line and the bell jar glazing assembly 2, does not occupy other production space, and does not affect the normal production of the bell jar glazing line.

[0042] Further, the glaze retaining assembly 3 includes at least two vertical brackets 31 and a glaze retaining plate, the upper end of the vertical bracket 31 is connected to the bottom of the glaze retaining plate, the lower end of the vertical bracket 31 is detachably connected to the tile conveying line, and the two vertical brackets 31 are respectively arranged on both sides of the tile conveying line and the glaze retaining plate;

[0043] The glaze retaining plate includes a plate bottom plate 321 and a surrounding block 322. The surrounding block 322 is vertically arranged around the top of the plate bottom plate 321. The surrounding blocks 322 located on both sides of the glaze retaining plate are provided with glaze flow openings 323. The width D1 of the glaze collecting component 4 in the vertical projection direction is greater than the width D2 of the glaze retaining plate.

[0044] like Figure 4 As shown, the glaze retaining plate is arranged above the tile conveying line through two vertical brackets 31 at both ends. The glaze retaining plate includes a plate bottom plate 321 and a fence 322 arranged around the plate bottom plate 321. The glaze retaining plate composed of the fence 322 and the plate bottom plate 321 has a certain accommodation space, which can carry the glaze flowing down from the bell jar glazing assembly 2. The fences 322 on both sides of the glaze retaining plate are provided with glaze flow ports 323, and the glaze intercepted by the glaze retaining plate flows out to the glaze collecting assembly 4 below through the glaze flow ports 323 on both sides.

[0045] To further explain, Figure 3 As shown, the width D1 of the glaze collecting component 4 in the vertical projection direction needs to be greater than the width D2 of the glaze retaining plate to ensure that the glaze flowing out of the glaze flow opening 323 flows into the glaze collecting component 4 .

[0046] Preferably, there are four vertical brackets 31 , with two vertical brackets 31 disposed on each side of the glaze retaining plate. The glaze retaining plate is installed and connected via multiple vertical brackets 31 , which is more stable.

[0047] Furthermore, the tray bottom plate 321 is inclined downward from the middle to both sides, glaze holes 324 are provided on both sides of the tray bottom plate 321, and a guide tube 325 is provided at the bottom of the tray bottom plate 321 corresponding to the position of the glaze holes 324 and extending downward.

[0048] The bottom plate 321 of the pan is tilted downward from the middle to both sides in a curved shape. The downward tilt of both sides of the bottom plate 321 of the pan is beneficial to accelerate the glaze in the glaze retaining assembly 3 to flow toward both sides and flow out through the glaze flow openings 323 on both sides.

[0049] Furthermore, glaze outlet holes 324 are provided on both sides of the tray bottom plate 321, and the glaze can flow out through the glaze outlet holes 324 or through the glaze outlet 323. In addition, a downwardly extending guide pipe 325 is provided at the position of the glaze outlet hole 324 at the bottom of the tray bottom plate 321, and the guide pipe 325 is connected to the glaze collecting component 4 through a hose, so as to avoid splashing and contaminating the product caused by the glaze flowing down. It is worth mentioning that there can be multiple glaze outlet holes 324 on both sides of the tray bottom plate 321, which are determined according to actual applications. Multiple glaze outlet holes 324 are conducive to the rapid outflow of glaze to the glaze collecting component 4, and the problem of glaze overflowing from the glaze retaining plate will not be caused by the glaze retaining plate discharging the glaze too slowly.

[0050] Furthermore, the height of the enclosure 322 is greater than 10 mm, the vertical distance from the top of the enclosure 322 to the bottom of the bell jar glazing assembly 2 is greater than 3 mm, and the vertical distance from the bottom of the tray bottom plate 321 to the conveying surface of the tile conveyor line is greater than 3 mm.

[0051] The height of the enclosure 322 is greater than 10 mm, so that the glaze retaining plate has a larger accommodating space and the glaze is not easy to overflow.

[0052] Furthermore, when the glaze retaining assembly 3 is located below the bell-shaped glazing assembly 2 to intercept the glaze, the vertical distance between the top of the enclosure 322 and the bottom of the bell-shaped glazing assembly 2 is greater than 3 mm, and the vertical distance between the bottom of the tray bottom plate 321 and the conveying surface of the tile conveyor line is greater than 3 mm, so as to avoid the glaze retaining assembly 3 from colliding with the bell-shaped glazing assembly 2 or the tiles during use, causing damage to the equipment.

[0053] Furthermore, the tile conveyor line includes a conveyor frame 11, a conveyor assembly 12 and two slide rails 13, wherein the conveyor assembly 12 is installed on the upper part of the conveyor frame 11, and the conveyor assembly 12 is used to convey tiles, and the two slide rails 13 are respectively arranged on both sides of the conveyor frame 11, and the slide rails 13 extend along the length direction of the conveyor frame 11;

[0054] The lower end of the vertical bracket 31 is provided with a slide rail groove 311 matching the slide rail 13, and the two sides of the slide rail groove 311 are symmetrical mounting arms 312. The lower part of the mounting arm 312 is provided with a clamping hole 313, and the pin 33 passes through the two clamping holes 313 to install the vertical bracket 31.

[0055] like Figure 1 and Figure 2As shown, the tile conveyor line includes a conveyor frame 11, a conveyor assembly 12 and two slide rails 13. The two slide rails 13 are respectively arranged on both sides of the conveyor frame 11. The lower end of the vertical bracket 31 is provided with a slide rail groove 311. The vertical brackets 31 on both sides are installed and connected with the slide rails 13 on both sides of the conveyor frame. Specifically, the two sides of the slide rail groove 311 are symmetrical mounting arms 312. The lower parts of the two mounting arms 312 are provided with clamping holes 313. When the vertical bracket 31 is clamped on the slide rail 13, the mounting arms 312 on both sides are located on both sides of the slide rail 13, and the clamping holes 313 are located at the bottom of the slide rail 13. The latch 33 is inserted from the clamping hole 313 on one side and passes through the other clamping hole 313, so that the vertical bracket 31 is installed on the slide rail 13.

[0056] The slide rail groove 311 at the lower end of the vertical bracket 31 matches the slide rail 13. After the vertical bracket 31 is installed and connected to the slide rail 13 through the slide rail groove 311, the vertical bracket 31 can move along the extension direction of the slide rail 13, thereby realizing the movement of the glaze barrier assembly 3 so that it is located below the bell jar glaze assembly 2 or away from the bell jar glaze assembly 2.

[0057] Furthermore, a limit block 314 is provided on the outer side of the mounting arm 312, and the latch 33 includes a horizontal block 331 and a vertical block 332, and the horizontal block 331 and the vertical block 332 are vertically connected to each other in an L shape, and the horizontal block 331 is inserted into the clamping hole 313, and the vertical block 332 is provided with a limit hole 333 matching the limit block 314.

[0058] like Figure 5 As shown, the latch 33 is L-shaped, and includes a horizontal block 331 and a vertical block 332 that are vertically connected to each other. Specifically, when the horizontal block 331 is horizontally inserted into the two clamping holes 313 to clamp the two mounting arms 312, the vertical block 332 of the latch 33 is located on the outside of one side of the mounting arm 312, and the vertical block 332 fits the mounting arm 312. The outside of the mounting arm 312 is provided with a stopper block 314 protruding outward, and the vertical block 332 is provided with a stopper hole 333 corresponding to the stopper block 314, then the stopper block 314 can pass through the stopper 333 of the vertical block 332, which is equivalent to the stopper block 314 locking the latch 33, so that the installation connection between the vertical bracket 31 and the slide rail 13 is more stable, and when the latch 33 is installed and locked on the vertical bracket 31, the vertical block 332 is located on the outside of the vertical bracket 31, which is more convenient for installation and disassembly.

[0059] Furthermore, the vertical cross-section of the slide rail 13 is in the shape of a triangle, a circle or a square;

[0060] The shape of the vertical cross section of the slide rail groove 311 corresponds to the shape of the vertical cross section of the slide rail 13 .

[0061] The shape of the vertical cross section of the slide rail 13 can be determined according to actual use, and can be triangular, circular or square; the shape of the slide rail groove 311 at the lower end of the vertical bracket 31 corresponds to the shape of the slide rail 13. When the vertical cross section of the slide rail 13 is square, the vertical bracket 31 is more firmly installed on the slide rail 13; when the vertical cross section of the slide rail 133 is circular, the production and molding of the slide rail groove 311 is more convenient and quick.

[0062] Furthermore, the connection between the vertical bracket 31 and the glaze retaining plate is provided with a plurality of reinforcing ribs 315. By providing the reinforcing ribs 315 at the connection between the vertical bracket 31 and the glaze retaining plate, the connection between the vertical bracket 31 and the glaze retaining plate is made more stable.
