Description

Technical Field

[0001] The utility model discloses a glaze removal device with a glaze pouring belt, and belongs to the technical field of glaze pouring equipment. Background Art

[0002] Glazed tiles are the most common type of tiles used in decoration. Glazing is one of the most important steps in the production process of glazed tiles. Glazing is one of the common glazing processes, and bell-shaped glazing devices are more common glazing devices in the prior art, such as the technical solution disclosed in the Chinese utility model patent with application number 201820207161.1, application date February 6, 2018, and patent name "A bell-shaped glazing device". The surface of the brick is glazed after passing through the glazing device driven by the conveyor belt, and then it is fired into shape through subsequent processes.

[0003] At present, a common defect in glazing equipment, including bell-type glazers, is that during the glazing process, glaze will fall on the belt surface at the same time, and glaze will adhere to the back of the tile when it runs on the belt. Then, during the high-temperature firing process in the kiln, the glaze on the back of the tile will adhere to the roller and affect the flatness of the roller, which not only reduces the service life of the roller, but more importantly, reduces the quality of the tile.

[0004] In the prior art, there are two ways to remove the glaze residue on the belt surface:

[0005] (1) The belt for conveying tiles is set to a multi-section type, so the glaze mostly remains on the belt surface in the glazing section. After the glazing is completed, it is transported by the other end of the belt. This method can reduce the impact of belt factors on tiles to a certain extent, but after long-term use, glaze will still remain on the belt surface outside the glazing section.

[0006] (2) The method of scraping glaze on the belt. For example, the technical solutions disclosed in the Chinese utility model patent with application number 202020883711.9, application date May 24, 2020, and patent name "A linear glazing device for ceramic tiles", and the Chinese utility model patent with application number 202223391451.1, application date December 19, 2022, and patent name "A glazing device for ceramic tile blanks". The problem with the scraping glaze method is that due to the high hardness of the glaze, the glaze is often solidified when the glaze is scraped on the belt, so the scraping effect is not ideal. If the strength of the scraping glaze is increased, it is easy to damage the belt. At the same time, if the glaze adheres to the back of the tile, it is easy to cause damage to the roller during the subsequent firing process. Utility Model Content

[0007] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a glaze belt deglazing device, which can wet the glaze remaining on the surface of the belt by setting a dripping mechanism, reduce the adhesion strength of the glaze to the belt, so that the scraping mechanism can completely remove the glaze adhered to the belt, avoid the glaze adhering to the back of the tile, and damage the roller during the firing process, thereby reducing the quality of the tile.

[0008] The technical solution adopted by the utility model to solve its technical problems is: the glaze belt deglazing device comprises multiple belts, and is characterized in that: a dripping mechanism is arranged on the moving path of the belt, the dripping mechanism is used to infiltrate the glaze remaining on the surface of the belt, and a scraping mechanism acting on the belt is also arranged, and the dripping mechanism and the scraping mechanism are arranged in sequence and at intervals along the moving direction of the belt.

[0009] Preferably, the dripping mechanism and the scraping mechanism are arranged at intervals on the return path of the belt, and are arranged in sequence along the moving direction of the return belt.

[0010] Preferably, the dripping mechanism is located above the belt on the return path.

[0011] Preferably, the feature is that the dripping mechanism comprises a plurality of drippers corresponding to the belts one by one, one end of the dripper is connected to the water supply container, the other end of the dripper is connected to the dripper, and the dripping port of the dripper is downwardly facing the corresponding belt.

[0012] Preferably, a valve is provided on each dropper.

[0013] Preferably, the scraper mechanism includes a scraper plate and a scraper bracket, and scraper plates corresponding to the belts are arranged on the surface of the scraper bracket, and the belt passes through the middle of the corresponding scraper plates.

[0014] Preferably, belt through holes corresponding to the belts are opened on the surface of the scraper bracket, and the belts pass through the corresponding belt through holes at the same time, and the scraper plate is arranged at the opening of the belt through holes.

[0015] Preferably, a collecting container is provided below the scraping mechanism.

[0016] Preferably, fixed frames are respectively provided on both sides below the belt, and the dripping mechanism and the scraping mechanism are fixed between the fixed frames on both sides.

[0017] Compared with the prior art, the utility model has the following beneficial effects: in the glaze belt deglazing device, a dripping mechanism is provided to wet the glaze remaining on the belt surface, thereby reducing the adhesion strength of the glaze to the belt, so that the scraping mechanism can completely remove the glaze adhered to the belt, thereby preventing the glaze from adhering to the back of the tile and causing damage to the roller during the firing process, thereby reducing the quality of the tile.

[0018] On the conveying belt, glaze will remain on its upper surface. If the dripping mechanism is set in the conveying direction of the belt, the water droplets will have limited effect on the wetting of the glaze and may affect the tiles on the belt surface. The dripping mechanism is set above the belt in the return direction and water drops are dripped. Since the residual glaze has been transferred to the bottom of the belt, the water drops can be gathered on the glaze and fully infiltrated.

[0019] The scraper plate is preferably made of polyurethane material to avoid damage to the belt while ensuring the scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0027] like Figure 1As shown, the glaze belt deglazing device includes a belt conveyor. The structure of the belt conveyor is the same as that of the prior art, including a pulley bracket 7. A pulley 6 is respectively arranged on the top of both sides of the pulley bracket 7, one of the pulleys 6 is a driving pulley, and the other is a driven pulley. The driving pulley rotates under the drive of a motor (not shown in the figure). The driving pulley and the driven pulley are connected by a belt 9, and the belt 9 includes a plurality of belts evenly arranged along the axial direction of the pulley 6. The ceramic tile 8 (brick blank) is placed on the surface of the plurality of belts 9 and moves under the drive of the belts 9.

[0028] A bell housing positioning column 4 ( Figure 1 Only one is shown in the figure), the bell 5 is fixed between two bell positioning columns 4. A glaze bucket installation column 3 is led out from the top of one of the bell positioning columns 4, and a glaze bucket 1 is fixed on the glaze bucket installation column 3. The bell 5 is located directly above the belt conveyor, and the glaze bucket is located directly above the bell 5. The glaze bucket 1 is provided with glaze material through an externally arranged glaze supply pipe, and the glaze material is delivered to the surface of the bell 5 through a lower glaze pipe 2 arranged at the bottom of the glaze bucket 1, and the ceramic tile is further glazed through the bell 5.

[0029] The specific structure, fixing method of the glaze bucket 1, the lower glaze tube 2, the glaze bucket mounting column 3, the bell jar positioning column 4, the bell jar 5 and the glaze adding tube, as well as the specific process of glazing are the same as those in the prior art, such as the technical solution disclosed in the Chinese utility model patent with application number 201820207161.1, application date February 6, 2018, and patent name “A bell-shaped glaze pouring device”, which will not be repeated here.

[0030] Combination Figure 2 A fixing frame 10 is provided on the surfaces of both sides of the pulley bracket 7, and the fixing frames 10 on both sides are located between the pulleys 6 on both sides. A dripping mechanism is provided between the fixing frames 10 on both sides. The dripping mechanism includes a water supply bracket 20, and a water supply tank 21 is provided on the top of the water supply bracket 20, and a plurality of dripping tubes 22 corresponding to the number of belts 9 are led out from the water supply tank 21.

[0031] Further integration Figure 3 The dripping mechanism also includes a fixing rod 14 horizontally arranged between the fixing frames 10 on both sides, and the lower ends of the dripping tubes 22 are fixed to the sides of the fixing rods 14 in sequence. A dripper 13 is arranged at the bottom of each dripping tube 22, and the dripper 13 is located just above the return belt 9, and the dripping port of the dripper 13 is downwardly facing the corresponding belt 9.

[0032] A valve is installed in each dripping pipe 22 to adjust the dripping frequency of the water drop 15 at the dripper 13. After the adjustment is completed, the water drop 15 drips from the dripper 13 to the surface of the return belt 9 at a certain frequency. Since the belt 9 here has completed the transportation of the tiles 8, the glaze 16 will remain on the lower surface of the belt 9 here. After the water drop 15 drips on the surface of the belt 9, it will flow downward along the contour of the belt 9 and converge to the lower surface of the belt 9 here, and mix with the glaze 16 remaining here, infiltrating the glaze 16, reducing the adhesion strength of the glaze 16 to the belt 9, facilitating the recovery of the glaze 16, and avoiding damage to the roller during firing due to the glaze 16 adhering to the back of the tile 8.

[0033] Although the dropper 22 can also be set above the belt 9 in the conveying direction (above the pulley 6), the glaze will remain on the upper surface of the belt 9 in the conveying direction, so the water drop 5 has a limited effect on the wetting of the glaze 16, and may affect the tiles 8 on the surface of the belt 9. However, by setting the dropper 22 above the belt 9 in the return direction (below the pulley 6) and dripping the water drop 15, the water drop 15 can be gathered at the glaze 16 and fully wetted.

[0034] Combination Figure 4 A scraping mechanism 12 is provided between the fixed frames 10 on both sides. The dripping mechanism and the scraping mechanism 12 are arranged in sequence along the return direction of the belt 9, and the dripping mechanism and the scraping mechanism 12 are arranged at intervals. A collecting container 11 is provided below the scraping mechanism 12. The glaze is scraped at the scraping mechanism 12 after being soaked by the dripping mechanism. The scraped glaze 16 drips into the collecting container 11 and is reused.

[0035] Further integration Figure 5 The scraper mechanism 12 includes a scraper bracket 18, which is horizontally arranged between the fixed frames 10 on both sides. Belt through holes 17 corresponding to the number of belts 9 are opened on the surface of the scraper bracket 18, and the return belts 9 pass through the corresponding belt through holes 17. A scraper plate 19 is arranged at the belt through holes 17, and the scraper plate 19 is preferably arranged on the side facing away from the conveying direction of the belt 9. An opening is arranged in the scraper plate 19, and the belt 9 passes through the opening of the scraper plate 19, and the outer periphery of the belt 9 is in contact with the inner wall of the opening of the scraper plate 19.

[0036] When the belt 9 passes through the scraper plate 19, the scraper plate 19 scrapes off the mixture of the water droplets 15 and the glaze 16, and the scraped mixture of the water droplets 15 and the glaze 16 falls into the collection container 11 for collection. The scraped belt 9 returns to the conveying direction to convey the subsequent tiles 8. The scraper plate 19 is preferably made of polyurethane material to avoid damage to the belt 9 while ensuring the scraping effect.

[0037] The specific working process and working principle are as follows: the bricks of the ceramic tile 8 are driven by the belt 9 on the surface of the belt conveyor to move, and when they move to the bell jar 5, the glaze is sent to the surface of the bell jar 5 through the lower glaze pipe 2 set at the bottom of the glaze bucket 1, and the ceramic tile 8 is further glazed through the bell jar 5. After the glazing is completed, the ceramic tile 8 is sent to the subsequent process.

[0038] The belt 9 that has completed the conveying is driven by the pulley 6 to move to the bottom of the pulley 6 and start the return journey. During the return journey, water droplets 15 drip from the dripper 13 to the surface of the belt 9 on the return journey at a certain frequency. Since the belt 9 here has completed the conveying of the tiles 8, the glaze 16 will remain on the lower surface of the belt 9 here. After the water droplets 15 drip onto the surface of the belt 9, they will flow downward along the contour of the belt 9 and gather at the lower surface of the belt 9 here, and mix with the glaze 16 remaining here to infiltrate the glaze 16.

[0039] Then the belt 9 moves to the scraper mechanism 12. While the belt 9 passes through the scraper plate 19 at the scraper mechanism 12, the scraper plate 19 scrapes off the mixture of water droplets 15 and glaze 16. The scraped mixture of water droplets 15 and glaze 16 falls into the collecting container 11 for collection. After completing scraping, the belt 9 returns to the conveying direction to carry out subsequent conveying of tiles 8.

[0040] In the prior art, a dilution tank and a raw material tank are generally provided for supplying the glaze 16. The raw material of the glaze 16 is diluted in a predetermined ratio in the dilution tank and then fed into the glaze bucket 1 through a glaze feeding tube. In the present glaze belt deglazing device, the glaze 16 collected by the collecting container 11 can be directly fed into the glaze bucket 1, or fed into the dilution tank and subjected to secondary treatment before being fed into the glaze bucket 1.

[0041] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
