Referring to fig. 1-5, a glaze spraying machine, includes frame 1, still includes diaphragm pump 2, glaze input tube 3, glaze output tube 4, connecting pipe 5, divides glaze jar and exhaust valve, diaphragm pump 2 sets up in frame 1, glaze input tube 3 sets up in frame 1, and glaze output tube 4 sets up in frame 1, connecting pipe 5 sets up in frame 1, the both ends of connecting pipe 5 are connected respectively glaze input tube 3 with glaze output tube 4, connecting pipe 5 is arranged in receiving the glaze from glaze input tube 3 unidirectionally, connecting pipe 5 is arranged in outputting the glaze toward glaze output tube 4 unidirectionally, the delivery outlet of diaphragm pump 2 communicates the middle part of connecting pipe 5, the output of glaze output tube 4 inserts divide the glaze jar, the exhaust valve sets up on glaze output tube 4 or divide the glaze jar.

Can be by the aforesaid, when starting to work, diaphragm pump 2 carries connecting pipe 5 from frit input tube 3 to partial frit, continue to work at diaphragm pump 2 under, partial frit in the connecting pipe 5 is carried frit output tube 4, partly frit is pumped to connecting pipe 5 again simultaneously, because mix the air in the frit, divide the pressure in the glaze jar higher under long-time work, thereby lead to diaphragm pump 2 to be difficult to again the frit from connecting pipe 5 squeeze into frit output tube 4 in, exhaust valve installs on frit output tube 4 or divide the glaze jar, thereby the exhaust action of accessible exhaust valve, reduce the pressure in the glaze jar, thereby make diaphragm pump 2 can carry the frit from connecting pipe 5 in the frit output tube 4 smoothly.

In the invention, the glaze conveyed by the glaze input pipe 3, the glaze output pipe 4 and the glaze distributing tank is dry glaze.

The connecting pipe 5 is used for unidirectional frit delivery, and for this purpose, in some embodiments, the connecting pipe 5 includes a pipe body 51, a first one-way valve 52 and a second one-way valve, the first one-way valve 52 is used for unidirectional frit feeding from the frit input pipe 3 to the pipe body 51, and the second one-way valve is used for unidirectional frit feeding from the pipe body 51 to the frit output pipe 4. In-service use, this 5 vertical settings of connecting pipe, corresponding frit input tube 3 sets up in the below of connecting pipe 5, and frit output tube 4 sets up in the top of connecting pipe 5 for the frit is carried from supreme down. And correspondingly the density of the gas is lower relative to that of the frit, so that the gas mixed in the frit is also correspondingly conveyed upwards.

The diaphragm pump 2 is used to provide the power for the frit delivery, and for this purpose, in some embodiments, the diaphragm pump 2 includes a cylinder 21, a piston assembly 22, a diaphragm body 23, and a driving unit 24; the cylinder body 21 is arranged on the frame 1; the piston assembly 22 is arranged in the cylinder 21, and the piston assembly 22 is in sliding fit with the inner wall of the cylinder 21; the cylinder body 21 is provided with a diaphragm hole communicated with the connecting pipe 5, the diaphragm hole is the output port, the diaphragm hole is blocked by the diaphragm main body 23, and the diaphragm main body 23 is fixedly connected with the piston assembly 22; the driving unit 24 is disposed on the frame 1, and the driving unit 24 is configured to drive the piston to reciprocate toward or away from the diaphragm main body 23. Drive piston assembly 22 along cylinder body 21 inner wall reciprocating motion through drive unit 24, when piston assembly 22 and cylinder body 21 inner wall relative slip, piston assembly 22 drives diaphragm main part 23 and moves together, when diaphragm main part 23 moves toward the direction of connecting pipe 5, the space in connecting pipe 5 reduces, make the frit extrude toward the direction of frit output tube 4, when diaphragm main part 23 moves toward the direction of keeping away from connecting pipe 5, the space in connecting pipe 5 increases, make the atmospheric pressure in connecting pipe 5 reduce, thereby in the connecting pipe 5 of the frit in the extraction frit input tube 3.

Preferably, the driving unit 24 includes a motor, a rotating shaft and an eccentric wheel, the rotating shaft is disposed on the frame 1, the rotating shaft and the frame 1 can rotate relatively, the rotating shaft is driven by the motor to rotate, the eccentric wheel is fixed on the rotating shaft, the eccentric wheel is hinged with the piston assembly 22 through a rocker, that is, two ends of the rocker are respectively hinged with the eccentric wheel and the piston assembly 22, and a crank-rocker mechanism is formed between the rocker and the eccentric wheel.

Furthermore, the drive unit 24 can also be an electric push rod. The piston assembly 22 is directly driven by the electric push rod to slide back and forth along the inner wall of the cylinder 21.

In the process of reciprocating the piston assembly 22, the piston assembly 22 needs to simultaneously bring the diaphragm main body 23 to perform synchronous sliding, and thus the diaphragm main body 23 and the piston assembly 22 need to be relatively fixed, for this reason, in some embodiments, the piston assembly 22 includes a piston main body 221, a gland 222, and a screw 223, the piston main body 221 is connected with the inner wall of the cylinder 21 in a sliding fit, the diaphragm main body 23 is disposed between the piston and the gland 222, the screw 223 penetrates through the diaphragm main body 23, and the gland 222 is fixedly connected with the piston through the screw 223, so that the gland 222 presses the diaphragm main body 23 on the piston. The diaphragm body 23 is pressed between the gland 222 and the piston assembly 22 by the gland 222 and the screw 223, so that the reciprocating motion of the piston assembly 22 drives the diaphragm body 23 to move.

Since some solid particles are present in the glaze, a portion of the solid particles are easily embedded between the gland 222 and the diaphragm body 23 during use, and the particles are easily damaged on the piston body 221 after long-term use, for this reason, in some embodiments, the piston assembly 22 further includes a gasket fixed on the piston body 221, and the gasket is disposed between the piston body 221 and the gland 222. By arranging the gasket on the top of the piston main body 221, damage to the piston by solid particles is avoided.

In addition, the gasket may be integrally formed with the piston body 221, that is, the thickness of the piston body 221 is increased. Further, the thickened piston body 221 needs to ensure that the position of the stroke end of the piston body 221 moving towards the diaphragm body 23 is not changed, and the user can reduce the stroke of the driving unit 24 to ensure that the stroke of the piston body 221 pushing the diaphragm body 23 is consistent, so that the generated extrusion force is consistent.

The stroke of the driving unit 24 is reduced, mainly by shortening the eccentricity of the eccentric wheel of the driving unit 24, so that the amount of dry glaze particles extracted by the diaphragm pump 2 at a time is reduced when the piston body 221 pulls the diaphragm body 23 to move towards the piston body 221 at a time. However, after the eccentricity of the eccentric wheel is reduced, the force arm of the motor driving the eccentric wheel to rotate is correspondingly reduced, so that the rotating speed of the motor can be faster under the same motor power, the number of times that the motor drives the piston main body 221 to do work in unit time is more, and the efficiency of extracting dry glaze particles can still be ensured. And the piston body 221 drives the diaphragm body 23 to reduce the stroke towards the direction of the diaphragm body 23, and the piston body 221 drives the diaphragm body 23 to keep the stroke towards the direction of the diaphragm body 23 unchanged, so that the extrusion force generated by the diaphragm pump 2 is greater than the extraction force, dry glaze particles can be extruded into the glaze distributing tank more easily, and the possibility of blockage of the connecting pipe 5 in the diaphragm pump 2 is reduced.

In practical use, the thickness of the gasket is 2mm, the eccentricity of the eccentric wheel is correspondingly reduced by 2mm, the jacking stroke of the diaphragm main body 23 towards the connecting pipe 5 is 9mm, and the pulling stroke of the diaphragm main body 23 towards the direction departing from the connecting pipe 5 is 5mm, so that the extraction force is smaller than the extrusion force.

To reduce the amount of solid particles that enter the frit between the gland 222 and the diaphragm body 23, in some embodiments, the gland 222 is in the shape of a truncated cone with a smaller area end surface abutting the diaphragm body 23. The provision of the gland 222 in the form of a truncated cone effectively reduces the contact area between the gland 222 and the diaphragm main body 23, and reduces the amount of solid particles that can be pressed by the gland 222 to the maximum.

In order to monitor the pressure inside the glaze spraying machine, in some embodiments, the glaze spraying machine further comprises a pressure sensor for detecting the pressure inside the glaze outlet pipe 4 or the glaze dispensing tank. The preferable pressure sensor is used for detecting the pressure in the glaze separating tank, and the pressure in the glaze separating tank and the pressure in the glaze output pipe 4 are approximately the same as each other due to the mutual communication of the glaze separating tank and the glaze output pipe.

In order to realize the conveying of the glaze by multiple stations and make the operation of the glaze spraying machine more efficient, in some embodiments, the glaze input pipe 3 includes a main feeding pipe 31, a feeding ring 33 and branch pipes 32, the feeding ring 33 is an annular pipe, the main feeding pipe 31 is communicated with the inside of the feeding ring 33, a plurality of branch pipes 32 are provided, the input end of each branch pipe 32 is respectively communicated with the inside of the feeding ring 33, the input ends of the connecting pipes 5 are connected with the output ends of the branch pipes 32 in a one-to-one correspondence manner, the glaze output pipe 4 includes an output main pipe 42 and a plurality of output branch pipes 41, the input ends of the output branch pipes 41 are connected with the output ends of the connecting pipes 5 in a one-to-one correspondence manner, all the output branch pipes 41 are communicated with the output main pipe 42, the output main pipe 42 is communicated with the glaze distributing tank, and the output ports of the diaphragm pumps 2 are in a one-to-connection pipes 5.

Since the air mixed with the glaze is eventually pushed into the glaze separating tank, so that more compressed air exists in the glaze separating tank, the output force of the diaphragm pump 2 is not enough to open the second check valve, and in some embodiments, the exhaust valve is communicated to the output manifold 42. Through the setting of this discharge valve, can arrange away the air of the compressing in the branch glaze jar, reduce the pressure in the branch glaze jar to make the second check valve can be opened.

The invention also provides a glaze conveying method using the glaze spraying machine, which comprises the following steps: set for the benchmark value of dividing the interior pressure of glaze jar, through pressure sensor response glaze output tube 4 or divide the interior pressure of glaze jar, carry glaze output tube 4 from glaze input tube 3 through diaphragm pump 2, after glaze is full of glaze input tube 3 and glaze output tube 4, if the pressure that pressure sensor sensed in the glaze output tube 4 is less than or equal to the benchmark value, carry out the pressure release to glaze output tube 4. Can effectively avoid the phenomenon of blockage of the glaze in the conveying process.

The exhaust valve may be an externally controlled valve, such as an externally controlled solenoid valve, electrically connected to the pressure sensor. The pressure of the glaze output pipe 4 is sensed by the pressure sensor, and the external control valve is opened when the pressure reaches a set reference value.
