Technical Field

Background
The existing glaze pouring technology generally comprises a bell jar type glaze pouring technology and a linear glaze pouring technology. For the bell jar type glaze pouring mode, glaze slip flows slowly after being homogenized by a bell jar surface and then glaze pouring is carried out on a brick blank, but the glaze pouring edge of the bell jar is a circular arc line (non-linear line), so that the amount of the glaze slip in the middle of the brick blank is less than that in the two sides in the glaze pouring process, and the glaze thickness of the brick blank is uneven. In particular, ceramic tiles used in inkjet printer processing require high flatness of the tile surface (glaze). Meanwhile, the glazing amount of the bell-type cannot be too small, otherwise, the glaze slip has too low specific gravity or too small fluidity, is easy to form ripples on the bell surface, and is not easy to form a glaze curtain (without viscosity).
In the linear glaze spraying technology, the glaze slurry is pressurized and then sprayed out through a gap, and although the glaze spraying mode can uniformly spray glaze on the brick blank, the glaze nozzle is easy to block, the glaze discharging state of the pressurized and sprayed glaze slurry belongs to a turbulent flow state, the glaze spraying state has large impact on the surface of the brick blank, and the problems of unsmooth glaze surface, stripes and the like can occur. Meanwhile, the gap of the glaze spraying opening has a large direct influence relationship on the glaze spraying amount and is difficult to be uniformly adjusted.
Furthermore, the glaze slip is prone to coagulation, and particularly, the glaze slip in a static state or flowing too slowly is prone to coagulation. Therefore, the existing technology needs to add an additional stirring device to relieve the problem of the coagulation of the glaze slurry, thereby increasing the structural complexity of the equipment and the later maintenance cost.
On the other hand, the two glaze pouring technologies have low control precision of glaze pouring amount, for example, the control is performed from the aspect of a glaze slurry output source, the bell jar type is performed by changing the glaze pumping amount of pouring and the bell jar surface, and the straight line type is performed by changing the glaze spraying pressure. Therefore, the conventional glaze pouring amount is generally controlled by changing the conveying speed (glaze pouring time) of a conveying belt for conveying the brick blanks according to the measurement and calculation of the actual glaze pouring amount under the stable working state of the glaze pouring equipment.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides a glaze pouring device, which comprises a glaze pouring plate 1 and a glazing mechanism for conveying glaze slurry to the glaze pouring plate 1;
the glazing mechanism comprises a glazing distribution roller 2, a metering roller 3 and a glaze blocking plate 4, wherein the glazing distribution roller 2 corresponds to the glazing pouring plate 1, the metering roller 3 is used for adjusting glazing amount, the glaze blocking plate 4 is arranged on two sides of the glazing distribution roller 2 and the metering roller 3, and a glaze storage pool 5 for caching glaze slip is formed among the metering roller 3, the glazing distribution roller 2 and the glaze blocking plate 4; the glaze slip in the glaze storage tank 5 is adhered to the rotating glaze distribution roller and moved to the glaze pouring plate 4.
Specifically, the glaze distribution roller 2 and the metering roller 3 are both provided with motors to control the rotation speed of the glaze distribution roller 2 and the metering roller 3 respectively, and the motors are preferably servo motors.
The glaze pouring device further comprises a glaze slip container 6 used for supplementing glaze slip to the glaze storage tank, the glaze slip container 6 is provided with a glaze discharging pipe 61 used for releasing the glaze slip, and the glaze discharging pipe 61 is correspondingly arranged above the glaze storage tank 5 so as to supplement the glaze slip to the glaze storage tank 5.
Moreover, drench the glaze ware still including being used for holding glaze groove 7 and returning the glaze pump, hold glaze groove 7 and correspond and locate the below of glazing mechanism, hold glaze groove 7 be equipped with return the glaze mouth 71 that the glaze pump communicates, the glaze slip in holding glaze groove 7 passes through return the glaze pump and carry to in the glaze slip container 6 to retrieve the glaze slip that flows out from hold glaze 5.
In order to ensure that the liquid level of the glaze storage tank 5 is lower than the highest point of the glaze distribution roller 2, the glaze slurry overflowing from the glaze storage tank 5 is prevented from directly flowing into the glaze pouring plate 1 beyond the glaze distribution roller 2, so that the glaze pouring amount is seriously influenced. The maximum point of the glazing roller 2 is higher than the maximum point of the metering roller 3. Since the glaze storage tank 5 is formed by combining the glaze distribution roller 2, the metering roller 3 and the oil baffle 4, when the glaze storage tank 5 overflows, glaze slurry flows out from a lower part, namely the metering roller 3, so that the maximum height of the liquid level of the glaze storage tank 5 is the highest point of the metering roller 3.
Because the glaze slip is transferred to on the glaze pouring plate 1 through the glaze distributing roller 2, in order to avoid the problem of overlarge fluctuation of the glaze pouring amount when the glaze pouring amount is regulated and controlled through the metering roller 3, the diameter of the glaze distributing roller is larger than that of the metering roller. Namely, when the glaze spraying amount needs to be roughly adjusted, the regulation and control can be carried out through the glaze distribution roller 2, and when the glaze spraying amount needs to be further finely adjusted and controlled, the regulation and control can be carried out through the metering roller 3.
Since the glaze slip itself has a high liquid viscosity and the liquid surface tension of the glaze reservoir 5 is high, the glazing principle of the glaze distribution roller 2 corresponds to pulling the glaze slip of one layer on the liquid surface of the glaze reservoir to the roller surface of itself by the adhesion of the roller surface to the glaze slip. Therefore, when the metering roll 3 and the glaze distribution roll 2 are turned in opposite directions, the metering roll 3 and the glaze distribution roll 2 compete for glaze slurry, and the glaze amount on the roll surface of the glaze distribution roll 2 is changed more finely and stably, so that the glaze pouring amount is changed.
Further, in order to further improve the precision control of the glazing amount, the roll surface adhesion coefficient of the glazing roller 2 is larger than that of the metering roller 3. When the roll surface adhesion coefficient of the metering roll 3 is lower than that of the glaze distribution roll 2, the competition capability of the glaze distribution roll 2 for the glaze slurry is greater than that of the metering roll 3 for the glaze slurry at the same linear speed. Therefore, the smaller the roll surface adhesion coefficient of the metering roll 3 is, the smaller the influence of the metering roll 3 on the glazing amount of the glazing roll 2 is, and the smaller the specific gravity is. That is, the smaller the adhesion coefficient of the metering roll 3 is compared with that of the glazing roll 2 at the same linear speed, the metering roll 3 can change the glazing amount of the glazing roll 2 more finely.
Preferably, the roll surface of the glazing roller 2 is made of rubber, and the metering roller 3 is made of metal. More preferably, the roll surface of the metering roll 3 is a smooth steel surface. The glaze distributing roller 2 and the metering roller 3 are made of materials with different hardness, and when the glaze distributing roller 2 and the metering roller 3 are in contact operation, abrasion between the glaze distributing roller and the metering roller can be reduced, so that the effective service life of the glaze distributing roller 2 is prolonged.
The glaze storage amount of the glaze storage pool 5 can affect the glazing amount of the glaze distribution roller 2 to a certain extent under the requirement of ultra-high precision, such as the glaze storage pool 5 is in an overflow state or is not in an overflow state.
Referring to fig. 2, in order to change the glaze discharging amount of the glaze discharging pipe 61, the glaze discharging pipe 61 is provided with a glaze discharging gap, that is, the glaze discharging gap is in a shape of a strip hole, a baffle 62 for changing the glaze discharging amount is arranged in the glaze discharging gap, the glaze discharging pipe is provided with a screw 63 for moving the baffle, one end of the baffle 62 is connected to the inner wall of the glaze discharging gap, the other end of the baffle 62 is in contact with one end of the screw 63, and the other end of the screw 63 penetrates out of the glaze discharging pipe 61 and is provided with a knob. The angle of inclination of the baffle 62 can be changed by rotating the screw 63, thereby changing the actual stripping width of the stripping gap.
Meanwhile, in order to further prolong the effective service life of the glaze distribution roller 2, an oil storage gap with a preset interval is reserved between the glaze distribution roller 2 and the metering roller 3, and the width of the glaze storage gap is smaller than 1 mm.
Preferably, the glaze spraying plate 1 is an arc-shaped plate with a smooth roll surface.
