Preferably, a reduction motor B32 is installed in the glaze spraying chamber 3, and the output shaft of the reduction motor B32 drives the rotating table 31 to rotate through a connecting disk; the rotating table 31 rotates driven by the connecting disk, and the blank on the rotating table 31 rotates accordingly, and all-round spraying is performed. A set of glaze spraying racks 4 is arranged between the two glaze spraying chambers 3, wherein a reduction motor A41 is arranged on the top of the glaze spraying cabinet 2, wherein the glaze spraying rack 4 is connected to the reduction motor A41, and the glaze spraying rack 4 can rotate left and right to realize switching spraying of the two glaze spraying chambers 3. Specifically, the top of the glaze spraying rack 4 is provided with a gear, and the rotation of the reduction motor A41 drives the gear to rotate and then drives the glaze spraying rack 4 to rotate left and right, and the angle of one-time rotation is generally 180 degrees. A set of box cover spraying mechanism 5 that swings back and forth is installed on the upper part of the glaze spraying frame 4. The box cover spraying mechanism 5 consists of a rotating cylinder 51 and a swing rod 52. The rotating cylinder 51 is connected to the swing rod 52. Preferably, the center hole of the rotating cylinder 51 is connected to the swing rod 52. The rotating cylinder 51 rotates by reversing the direction of the inlet and outlet air, driving the swing rod 52 to swing back and forth. Two spray guns 53 are installed on the swing arm 52, namely spray gun G1531 and spray gun G2532. These two spray guns 53 are responsible for spraying the water tank cover. Preferably, two sets of screw adjustment devices 54 are provided on the swing arm 52. The two spray guns 53 are installed on the screw. The two spray guns 53 adjust the up and down height and spray angle through the nut on the screw. The nut can be rotated to a specified height to adjust the height, and the spray angle can be adjusted by pre-setting the angle of the spray gun 53 and then fixing the spray gun 53. By adjusting the up and down height and spray angle of the two spray guns 53 through the nut on the screw, the flat coating of the tank cover can be made uniform. Among them, the swing arm 52 swings back and forth, and the spray gun 53 adjusts the angle and height, so that the flat coating of the tank cover can be made uniform in all directions. A set of tank side spraying mechanism 6 that reciprocates up and down is installed at the lower part of the glaze spraying frame 4. The tank side spraying mechanism 6 is composed of a telescopic cylinder A61 and a telescopic rod A62. The telescopic cylinder A61 and the telescopic rod A62 are connected. Preferably, the center hole of the telescopic cylinder A61 is connected to the telescopic rod A62.

The blank is placed on the rotating table 31 manually in advance so that the blank can be transferred to the glaze spraying chamber 3 for spraying immediately after the operation of the other spraying chamber is completed. The entire spraying work is only stopped during the rotation process of the glaze spraying rack 4, and the spraying is continuous at other times, which greatly improves the work efficiency. At the same time, the distance between the two spraying chambers is very close, and the staff only needs to stand near the glaze spraying cabinet 2 to switch, without the need for an assembly line, and the manual loading and unloading of products is convenient, with a small footprint and low equipment cost. When spraying, the workpiece is directly placed on the rotating table 31, and there is no trouble of the assembly line requiring a tooling plate. The use of two sets of mechanisms, the box cover spraying mechanism 5 and the box side spraying mechanism 6, is equivalent to the configuration of two conventional robots, and the production efficiency is high.

[0029] Preferably, in order to ensure the safety of the staff, the front of the glaze spray cabinet 2 is provided with a left and right sliding door device 7, which is composed of a telescopic cylinder B71, a protective door 72 and a slide rail 73. The slide rail 73 is arranged at the upper and lower ends of the glaze spray cabinet 2, and the protective door 72 is installed on the slide rail 73. The protective door 72 is provided with a telescopic rod B74. The central hole of the telescopic cylinder B71 is connected to the telescopic rod B74. The telescopic cylinder B71 realizes left and right reciprocating motion through the reversal of the inlet and outlet air, driving the telescopic rod B74 to reciprocate left and right, and then completing the left and right movement of the protective door 72. The glaze spray cabinet 2 corresponding to which side the protective door 72 moves to starts the spraying work, ensuring the closed operation during spraying to prevent dust from polluting the working environment and affecting the staff. The telescopic cylinder B71 of the sliding door is linked with other pneumatic components or reduction motors in the glaze spray cabinet 2. In order to ensure personal safety when the sliding door is moving, an automatic light curtain protection function is added. If someone enters the dangerous area during the movement of the sliding door, a sensor is set on the sliding door, usually an infrared sensor. When someone enters, the sensor is triggered, and then the telescopic cylinder B71 is controlled to brake, and the sliding door stops moving immediately.

The pulse backflush device 94 is connected to the filter element 93. The pulse backflush device 94 regularly introduces high-pressure air into the interior of the filter element 93 to make the dust attached to the outer surface of the filter element 93 fall off, thereby ensuring the filtering effect of the filter element 93. The filter element 93 is coated at the tail of the dust removal air duct 10, and the ash receiving hopper 95 is arranged at the bottom of the dust removal air duct 10. The dust in the spray glaze cabinet 2 passes through the filter element 93 medium from the outer surface of the filter element 93 to the inside of the filter element 93 under the suction force of the dust exhaust fan 92. All the gases inside the filter element 93 are collected in the clean air chamber on the upper part of the dust removal cabinet 9. These gases are discharged to the outside through pipelines. The dust blocked by the outer surface of the filter element 93 falls into the ash hopper 95 and is regularly collected and reused.

[0032] Preferably, a pneumatic solenoid valve 12 is provided on the ventilation duct 11, and the pneumatic solenoid valve 12 controls the ventilation duct 11 to be connected with the dust removal cabinet 9. The pneumatic solenoid valve 12 is linked with the telescopic cylinder A61 and the rotating cylinder 51 of the left and right spraying rooms, that is, when the left glaze spraying room 3 is spraying, the solenoid valve controls the ventilation duct 11 on the left to be connected with the dust removal cabinet 9, and when the right side is spraying, the solenoid valve controls the ventilation duct 11 on the right to be connected with the dust removal cabinet 9, so as to better complete the dust removal.

[0033] Preferably, a control cabinet is arranged on the right side of the glaze spraying cabinet 2, and the control cabinet includes a PLC control cabinet 13 and a gas control and solenoid valve control cabinet 14. Through different control cabinets, different components of the whole device are controlled to work in an orderly manner.

[0034] The specific method of use of the present invention is:

[0035] First, the position of the protective door 72 is set by the left and right sliding door device 7. When the protective door 72 is on the left, the embryo 15 is placed on the rotating table 31 of the right glaze spraying chamber 3. The rotating table 31 of the right glaze spraying chamber 3 starts to rotate under the drive of the reduction motor B32, and then the glaze spraying frame 4 is rotated to the right. Specifically, the glaze spraying frame 4 is driven to rotate by the reduction motor A41. After the rotatable glaze spraying frame 4 reaches the right, the box cover spraying mechanism 5 starts to work. Due to the sealing effect of the glaze spraying frame 4, the right glaze spraying chamber 3 is in a sealed working state to prevent dust from overflowing. The rotating cylinder 51 of the box cover spraying mechanism 5 drives the swing rod 52 to swing back and forth. When the glaze spraying frame 4 rotates to the right, the swing rod 52 swings back and forth. The tank cover of the embryo 15 is sprayed. During spraying, the two spray guns 53 on the swing rod 52, spray gun 53G1 and spray gun 53G2, spray the tank cover. Here, the height and angle of spray gun 53G1 and spray gun 53G2 can be adjusted by the screw adjustment device 54 to better complete the spraying of the tank cover; while the tank cover spraying mechanism 5 is working, the tank side spraying mechanism 6 below also starts to reciprocate up and down under the action of the telescopic cylinder A61. The tank side spraying mechanism 6 is composed of a telescopic cylinder A61 and a telescopic rod A62. Two spray guns 53 are installed on the telescopic rod A62, namely spray gun 53G3 and spray gun 53G4. Spray gun 53G3 and spray gun 53G4 spray the side of the water tank to make its coating uniform. Here, the relative height of the spray gun 53G3 and the spray gun 53G4 can be adjusted by the slider. While spraying up and down, the present application also adds an automatic cleaning device for the spray gun 53. After every 4 spraying operations, the water control solenoid valve 85 and the compressed air control solenoid valve 83 of the device will automatically clean the spray gun 53. When cleaning, first spray water on the spray gun 53 for 2 seconds to flush the glaze slurry on the surface of the spray gun 53, and then spray compressed air for 1 second to blow dry the water on the spray gun 53 to ensure that the spray gun 53 is unobstructed. During the entire spraying process, the dust extraction fan 92 in the dust removal cabinet 9 has been extracting the generated dust, and the pulse backblowing device 94 regularly introduces high-pressure air into the interior of the filter element 93 to remove the dust attached to the outer surface of the filter element 93. , ensuring the filtering effect of the filter element 93. Under the suction force of the dust exhaust fan 92, the dust in the glaze spraying cabinet 2 passes through the filter element 93 medium from the outer surface of the filter element 93 to the inside of the filter element 93. All the gases inside the filter element 93 are collected in the clean air chamber on the upper part of the dust removal cabinet 9. These gases are discharged to the outside through pipelines. The dust blocked by the outer surface of the filter element 93 falls into the ash receiving hopper 95 and is regularly collected and reused to complete the spraying work of the embryo 15 in the right side glaze spraying room 3. When spraying on the right side, the embryo 15 can be placed on the left rotating table 31. When the right side is completed, the glaze spraying frame 4 rotates to the left position. At the same time, the left and right sliding door devices 7 are driven, and the protective door 72 reaches the left position to spray the left side. This is repeated to complete the continuous operation.

[0036] The present invention comprehensively considers the advantages and disadvantages of the assembly line and the single-cabinet glaze spraying machine, and flexibly combines pneumatic, electrical, mechanical and other technologies together, so that the double-station full-automatic water tank glaze spraying machine is energy-saving and environmentally friendly, cost-effective, and has stable and reliable spraying quality; by rotating the rotating table in the two glaze spraying chambers, the spraying mechanism on the glaze spraying frame cyclically sprays the embryos 15 of the two glaze spraying chambers, which can achieve continuous spraying work, and because a set of glaze spraying frames is cleverly arranged between the two glaze spraying chambers, the floor space of the glaze spraying cabinet is greatly reduced, and the production and maintenance costs are low; by The box cover spraying mechanism and the box side spraying mechanism arranged on the glaze spraying frame spray the embryo 15 at the same time, and the spraying efficiency is twice that of the general glaze spraying cabinet. The embryo 15 is sprayed in all directions by four spray guns, and the spraying quality is stable. The four spray guns are cleaned by the automatic spray gun cleaning device, which further ensures the spraying quality of the embryo 15; by arranging a dust removal cabinet and a dust removal air duct to receive the dust generated after spraying, the dust removal efficiency is high, and the spraying process avoids dust overflow, which has a significant effect of energy saving and environmental protection, and the glaze utilization rate is high, reducing production costs.
