Description
Technical Field
[0001] This utility model relates to the field of ceramic glazing equipment technology, and more specifically, to a dome-shaped straight-edge glazing equipment. Background Technology
[0002] The dome-shaped straight-edge glazing applicator, as a glazing device in ceramic production, is widely accepted and recognized by ceramic manufacturers due to its simple structure, easy operation, and stable and reliable glazing quality, and has been promoted and applied. Existing dome-shaped straight-edge glazing applicators include a mounting bracket, a dome-shaped straight-edge glazing assembly, a glaze supply funnel, and a glaze collection tray. The dome-shaped straight-edge glazing assembly includes a dome-shaped straight-edge glaze plate, which is equipped with a surrounding glaze baffle. The top of the guide surface of the dome-shaped straight-edge glaze plate is spherical, and the front edge is a straight-edged blade. The guide surface of the dome-shaped straight-edge glaze plate is located at the front, and the part connecting the spherical surface and the straight-edged blade is an arc-shaped guide surface. The surrounding glaze baffle extends to the left and right edges of the arc-shaped guide surface.
[0003] During glazing, the unglazed ceramic (tile, slab, daily-use porcelain) blanks to be glazed are conveyed by a conveyor, passing under the glazing assembly at the straight edge of the dome. A glaze supply pump delivers glaze from the glaze tank to the glaze funnel. The glaze flows out from the ball valve and connecting pipe below the funnel, reaching the guide surface of the glaze plate at the straight edge of the dome. The glaze slurry disperses on the guide surface, thinning, homogenizing, and defoaming under the surface tension of the fluid, ultimately forming a continuous and uniform glaze curtain at the lower edge of the curved guide surface, and a uniform glaze film on the surface of the unglazed ceramic (tile, slab, daily-use porcelain) blank, thus completing the glazing process. The drawbacks of this method include: glaze slurry accumulates at the edge baffles on the left and right sides of the curved guide surface, resulting in a thicker glaze at both ends of the glaze waterfall compared to the middle area, leading to a shorter effective working width of the glaze waterfall. Utility Model Content
[0004] The present invention provides a dome-shaped straight-edge glazing device that can solve the above-mentioned problems.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] This utility model provides a dome-shaped straight-edge glazing device, including a glaze supply funnel, a glaze recovery tray, and a dome-shaped straight-edge glazing assembly. The dome-shaped straight-edge glazing assembly includes a dome-shaped straight-edge glaze distribution plate, which is provided with a surrounding glaze baffle plate. The top of the guide surface of the dome-shaped straight-edge glaze distribution plate is spherical, and the front edge is a straight-edge cut. The guide surface of the dome-shaped straight-edge glaze distribution plate is forward, and the part connecting the spherical surface and the straight-edge cut is an arc-shaped guide surface. Glaze release channels are provided on both the left and right sides of the arc-shaped guide surface, arranged in the front-back direction. The two ends of the surrounding glaze baffle plate are located behind the arc-shaped guide surface and extend to the glaze release channels on both sides. The front end of the glaze release channel leads to the glaze recovery tray.

[0008] As a further description of the above technical solution: the fine-tuning glaze release gate mechanism includes a sliding base fixed to the forming part of the glaze release guide groove, a fine-tuning slider linearly slidingly engaged with the sliding base, a fine-tuning screw threadedly connected to the sliding base, and a rubber gate plate fixed to the fine-tuning slider and matched with the glaze release guide groove; the upper end of the fine-tuning screw is provided with a fine-tuning handle, the lower end is rotatably engaged with the fine-tuning slider, and is axially fixed relative to the fine-tuning slider.
[0009] As a further description of the above technical solution: the dome straight-edge glazed plate is provided with an angle adjustment device, including a mounting bracket, a base plate fixed to the mounting bracket and provided with two rotating connection mechanisms, and a lifting bolt threaded to the mounting bracket and abutting against the dome straight-edge glazed plate above; the glaze release guide groove forming element is fixedly connected to the dome straight-edge glazed plate as a whole, and the glaze release guide groove forming elements on the left and right sides are respectively connected to the base plate through the two rotating connection mechanisms; the lifting bolt and the two rotating connection mechanisms are arranged in an isosceles triangle three-point layout.
[0010] As a further description of the above technical solution: the rotating connection mechanism includes a rotating shaft, a locking bolt, and a horizontal adjusting bolt; the base plate is provided with a rotating groove; one end of the rotating shaft is rotatably engaged with the forming element of the glaze release guide groove, and the other end is engaged in the rotating groove; the horizontal adjusting bolt is threaded to the base plate from bottom to top, and its upper end extends into the rotating groove and abuts against the rotating shaft, so as to drive the rotating shaft to slide up and down along the rotating groove; the locking bolt is threaded to the base plate from top to bottom, and its lower end extends into the rotating groove, so as to lock the rotating shaft in the rotating groove.
[0011] As a further description of the above technical solution: a flow-stabilizing ring and / or a flow-distributing semi-circular ring are provided on the guide surface of the spherical straight-edge glaze plate located directly below the glaze supply funnel.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1) After the glaze reaches the front end of the edge baffle plate, some of the glaze will enter the glaze release guide channel and flow along the glaze release guide channel to the glaze receiving tray. Some of the glaze on both sides of the arc-shaped guide surface enters the glaze release guide channel, thereby reducing the accumulation of glaze at the edge baffle plate. This allows the two ends of the glaze waterfall to be closer to the thickness of the middle of the glaze waterfall, thus obtaining a larger effective working width.
[0014] 2) After adding the horizontal glaze strip, the glaze slurry gathers on the inner side of the horizontal glaze strip and overflows from the top of the horizontal glaze strip. It flows through the arc-shaped guide surface of the spherical straight edge glaze plate and forms a uniform glaze waterfall at the lower edge. The addition of the horizontal glaze strip and the control of the amount of glaze entering the side glaze release tank by finely adjusting the opening of the glaze release gate mechanism can achieve a more uniform glaze curtain thickness. In addition, the setting of the horizontal glaze strip can further eliminate the surge and flow fluctuation of the glaze slurry entering the glaze applicator, eliminate wood grain glaze film defects, and further improve the glazing quality.
[0015] 3) The tilt angle adjustment device can adjust the front and rear tilt angle of the dome straight edge glazing plate to adjust the distribution flow rate of the glaze slurry on the guide surface of the dome straight edge glazing plate.
[0016] 4) When the level of the glazing blade is not up to standard, the glaze will have a left-right weight deviation. The rotating connection mechanism has been further designed with a rotating shaft adjustment structure. Only the level adjustment bolt needs to be finely adjusted to drive the corresponding rotating shaft to slide up and down along the rotating groove, thereby finely adjusting the level of the blade to meet the standard and achieving consistent left-right weight. After adjustment, tighten the top locking bolt to lock it in place, ensuring the continuous and stable glazing quality.
[0017] 5) This utility model can avoid the local abrupt changes in the glaze slurry at both ends of the distribution semicircular ring, which leads to uneven glaze film and defects such as trumpet-shaped stripes. In addition, the glaze slurry flows steadily in the area between the stabilizing small ring and the distribution semicircular ring, which more thoroughly eliminates the impact and surge of glaze entry, resulting in better glazing quality.
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0026] Please refer to Figure 1 This embodiment provides a dome-shaped straight-edge glazing device, including a glaze supply funnel 2, a glaze recovery tray 4, and a dome-shaped straight-edge glazing assembly 5.
[0027] like Figure 1 and Figure 2 As shown, the spherical dome straight-edge glazing assembly 5 includes a spherical dome straight-edge glazing plate 6, with a surrounding glazing baffle plate 7. The top of the guide surface of the spherical dome straight-edge glazing plate 6 is spherical, and the front edge is a straight-edge cutter. The guide surface of the spherical dome straight-edge glazing plate 6 is forward, and the part connecting the spherical surface and the straight-edge cutter is an arc-shaped guide surface 13. Glaze release channels 8 are provided on both the left and right sides of the arc-shaped guide surface 13, arranged in the front-back direction. The two ends of the surrounding glazing baffle plate 7 are located behind the arc-shaped guide surface 13 and extend to the glaze release channels 8 on both sides. The front end of the glaze release channel 8 leads to the glaze collection tray 4 for recycling glaze. A flow stabilizing ring 10 and a flow distribution semi-circular ring 11 are provided on the guide surface of the spherical dome straight-edge glazing plate 6 directly below the glaze supply funnel 2.
[0028] The edge-mounted glaze plate 7 is tightly fitted to the rear arc edge of the dome straight-edge glaze plate 6 and terminates near the end of the arc edge on the side of the dome straight-edge glaze plate 6. This guides the glaze slurry, allowing it to be distributed evenly on the surface of the dome straight-edge glaze plate 6. This prevents the glaze slurry from flowing onto the surface of the already glazed bricks below and contaminating the products. It also prevents the glaze slurry from flowing onto the glazing line and the ground, thus avoiding contamination of the work facilities and the environment, and preventing waste of glaze.
[0029] The left and right side glaze release channels 8 are connected to the front end of the edge baffle plate 7. At the same position in the front-back direction, the bottom of the glaze release channel 8 is lower than the guide surface of the dome straight-edge glaze plate 6. After the glaze reaches the front end of the edge baffle plate 7, part of the glaze will enter the guide channel and flow along the guide channel to the glaze recycling tray 4, and then enter the glaze bucket (not shown in the figure) for recycling. Part of the glaze on both sides of the dome straight-edge glaze plate 6 enters the glaze release channel 8, thereby reducing the accumulation of glaze at the edge baffle plate 7, which allows the two ends of the glaze waterfall to be closer to the thickness of the middle of the glaze waterfall, thus obtaining a larger effective working width. This design can expand the range of product specifications that the glazing equipment can adapt to.
[0030] In an optional embodiment of this utility model, the glaze release guide groove 8 is equipped with a fine-tuning glaze release gate mechanism 9; a horizontal glaze-blocking strip plate 12 is provided at the rear of the arc-shaped guide surface 13, and the two ends of the horizontal glaze-blocking strip plate 12 extend to the left and right edges of the arc-shaped guide surface 13 respectively. The rubber gate plate 20 of the fine-tuning glaze release gate mechanism 9 and the horizontal glaze-blocking strip plate 12 are coplanar.
[0031] In this embodiment, the addition of the horizontal glaze baffle 12 causes the glaze slurry to accumulate inside the horizontal glaze baffle 12, then overflow from the top of the horizontal glaze baffle 12, flow through the arc-shaped guide surface 13, and form a uniform glaze waterfall at the lower edge. By adjusting the opening of the rubber gate 20 of the fine-tuning glaze release gate mechanism 9, the amount of glaze entering the glaze release guide groove 8 can be controlled. Combined with the design of the horizontal glaze baffle 12, a more uniform glaze curtain thickness can be obtained. The horizontal glaze baffle 12 can also further eliminate the surge and flow fluctuation of the glaze slurry entering the glaze applicator, eliminate wood grain-like glaze film defects, and thus further improve the glazing quality.
[0032] In one optional embodiment of this utility model, such as Figure 4 As shown, the fine-tuning glaze release gate mechanism 9 includes a sliding base 18 fixed to the forming element of the glaze release guide groove 8, a fine-tuning slider 19 linearly slidingly engaged with the sliding base 18, a fine-tuning screw 17 threadedly connected to the sliding base 18, and a rubber gate plate 20 fixed to the fine-tuning slider 19 and matched with the glaze release guide groove 8; the upper end of the fine-tuning screw 17 is provided with a fine-tuning handle 25, and the lower end is rotatably engaged with the fine-tuning slider 19 and axially fixed relative to the fine-tuning slider 19.
[0033] By turning the fine-tuning handle 25, the fine-tuning screw 17 can be rotated, which in turn drives the fine-tuning slider 19 to move up and down in the groove of the groove base 18, thereby controlling the slight rise and fall of the rubber gate 20, and thus precisely adjusting and controlling the glaze discharged through the glaze release guide groove 8, ultimately achieving the ideal effect of fine-tuning and controlling the uniform thickness of the glaze film on the top of the horizontal glaze strip 12.
[0034] In one optional embodiment of this utility model, such as Figure 2 and Figure 3As shown, the dome-shaped straight-edge glazed plate is equipped with an angle adjustment device, including a bracket, a base plate fixed to the bracket and equipped with two rotating connection mechanisms, and a lifting bolt threaded to the mounting bracket and abutting against the upper dome-shaped straight-edge glazed plate; the glaze release guide groove is fixedly connected to the dome-shaped straight-edge glazed plate as a whole, and the glaze release guide grooves on the left and right sides are respectively connected to the base plate through two rotating connection mechanisms; the lifting bolt and the two rotating connection mechanisms are arranged in an isosceles triangle three-point layout. Figure 4 As shown, the rotating connection mechanism includes a rotating shaft, a locking bolt, and a horizontal adjusting bolt; the base plate is provided with a rotating groove; one end of the rotating shaft is rotatably fitted into the forming part of the glaze release guide groove, and the other end is locked in the rotating groove; the horizontal adjusting bolt is threaded to the base plate from bottom to top, and its upper end extends into the rotating groove and abuts against the rotating shaft, so as to drive the rotating shaft to slide up and down along the rotating groove; the locking bolt is threaded to the base plate from top to bottom, and its lower end extends into the rotating groove, so as to lock the rotating shaft in the rotating groove.
[0035] By tightening the lifting bolts, the rear part of the dome straight-edge glazing plate can be slightly raised and lowered, and the entire glazing component will rotate around the pivot, thereby finely adjusting the tilt angle of the dome straight-edge glazing plate.
[0036] When the blade of the glazing tool is not level, the weight of the glaze may deviate from left to right. In this case, simply adjust the leveling bolt to drive the corresponding rotating shaft to slide up and down along the rotating groove, thereby adjusting the level of the blade to meet the standard and achieving consistent weight on both sides. After adjustment, tighten the top locking bolt to ensure the glazing quality remains stable.
[0037] As can be seen, the newly designed and improved three-point support tilt adjustment device can very conveniently and accurately adjust the horizontal and tilt angle of the glaze applicator blade, thereby very accurately adjusting the weight of the left, center and right sides of the glaze curtain to make them consistent, ensuring reliable and stable glazing quality.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
