Description

Technical Field

[0001] The invention relates to the technical field of ceramic glaze spraying, in particular to a tightly attached type ceramic automatic glaze spraying machine. Background Art

[0002] Ceramic glazing is an important process in the ceramic production process. It means that the prepared glaze is evenly sprayed or attached to the surface of the ceramic body through specific equipment and technology. By spraying glaze, the ceramic products can obtain a smooth and beautiful surface, and at the same time give them different colors, textures and properties. In the process of spraying glaze, it is necessary to precisely control the concentration of the glaze, the pressure and angle of the spraying, etc., to ensure the uniformity and thickness of the glaze layer. Different quality and artistic value play a vital role.

[0003] Since the ceramic body presents various states in actual form, and the diameters of various parts of the bottle body of the ceramic body are not uniformly distributed, the spacing of traditional spray guns in actual applications cannot be flexibly and effectively adjusted according to actual conditions, while the amount of sprayed glaze remains fixed. As a result, when spraying the bottleneck and bottle body of the ceramic body, due to the structural differences of their respective parts and the inability to adjust the spacing of the spray guns, the thickness of the glaze sprayed on these different parts is different, resulting in an unsatisfactory overall spraying effect and failure to achieve the expected good effect and quality standards.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0032] The top of the workbench 1 is fixedly connected to a support frame 12, the top of the inner wall of the support frame 12 is fixedly connected to a slide rail 13, an electric slider 14 is slidably connected in the slide rail 13, a lifting cylinder 15 is fixedly connected to the bottom of the electric slider 14, a horizontal plate 16 is fixedly connected to the output end of the lifting cylinder 15, a spraying assembly 17 is arranged at the bottom of the horizontal plate 16, the spraying assembly 17 includes two bases 171 and two connecting rods 172, and slide grooves are symmetrically provided at the bottom of the horizontal plate 16;

[0033] The two bases 171 are slidably connected in the slide groove, and the bottom of the cross plate 16 is movably connected with a rotating rod 173 through a bearing. One end of the connecting rod 172 is rotatably connected to the rotating rod 173, and the other end of the connecting rod 172 is rotatably connected to the side wall of the base 171. The bottom of the base 171 is fixedly connected with a connecting frame 174, and the bottom of the cross plate 16 is fixedly connected with an electric push cylinder 18, and the output end of the electric push cylinder 18 is fixedly connected to one of the bases 171.

[0034] The connecting frame 174 is fixedly connected to a plurality of sleeves 175, the sleeves 175 are slidably connected to hollow slide bars 176, one end of the hollow slide bars 176 is fixedly connected to a nozzle 177, a conduit connected to the nozzle 177 is placed inside the hollow slide bars 176, and the side walls of the connecting frame 174 are fixedly installed with micro electric push rods 178 corresponding to the number of sleeves 175, and the output ends of the micro electric push rods 178 are fixedly connected to the bottom of the hollow slide bars 176;

[0035] An electric lifting plate 26 is fixedly connected to the top of the workbench 1 , a motor 1 is fixedly installed on the top of the electric lifting plate 26 , and a rectangular block 27 matching the rectangular limiting groove 11 is fixedly connected to the output end of the motor 1.

[0036] A lifting push rod 19 is symmetrically fixed to the bottom of the electric slider 701, and a connecting block 20 is fixedly connected to the output end of the lifting push rod 19. An electric telescopic clamping plate 21 is fixedly installed on the top of the connecting block 20. It should be noted that the electric telescopic clamping plate 21 is an existing mechanism with a telescopic function, which is used to clamp the outer circumferential wall of the ceramic.

[0037] An electric rotating frame 23 is fixedly installed at the bottom of the electric slider 702, and two arc rods 24 are fixedly connected to the bottom of the electric rotating frame 23. A high-definition recorder 25 is fixedly installed on the arc rod 24 and the top of the workbench 1, and a control panel 28 is fixedly installed on the top of the workbench 1.

[0038] During the specific setting, the ceramic body to be sprayed with glaze is first placed on the top of the workbench 1, and the electric slider 702 drives the electric rotating frame 23 to move until the two arc rods 24 are located on both sides of the ceramic body. The electric rotating frame 23 drives the arc rod 24 to rotate, thereby driving the high-definition recorder 25 installed on the inner side of the arc rod 24 to rotate, thereby realizing the scanning of the surface image of the circumferential side wall of the ceramic body. It should be noted that the high-definition recorder 25 includes a camera and a scanner. The camera is used to take images of the outer and inner sides of the circumference of the ceramic body and to warn of damage, while the scanner is used to scan the inner and outer contours of the circumference of the ceramic body, so that the spacing between the nozzle 177 at different positions and the ceramic body is the same, so that the thickness of the glaze sprayed on the surface of the ceramic body is kept consistent;

[0039] If there is damage inside and outside the circumference of the ceramic body, it means that the ceramic body cannot be sprayed with glaze, that is, it is marked as an unqualified ceramic body. At this time, the ceramic body is clamped by the electric telescopic clamping plate 21 and transported to the top of the electric slider 4. The electric slider 4 will directionally transport the unqualified ceramic body to the recycling area;

[0040] If there is no damage on the inside and outside of the circumference of the ceramic body, the electric slider 701 drives the lifting push rod 19 to move synchronously, and then the electric telescopic clamping plate 21 clamps and lifts the outside of the circumference of the ceramic body, and the high-definition recorder 25 installed on the top of the workbench 1 takes an image of the bottom of the ceramic body and warns of damage;

[0041] If the bottom of the ceramic body is damaged, it is marked as an unqualified ceramic body. At this time, the electric telescopic clamping plate 21 is used to transport it to the top of the electric slider 4, and the electric slider 4 directionally transports the unqualified ceramic body to the recycling area;

[0042] If there is no damage on the bottom of the ceramic body, it means that the ceramic body can be sprayed with glaze, that is, it is marked as a qualified ceramic body. At this time, the ceramic body is placed on the top of the turntable 10 through the electric telescopic clamping plate 21, and the electric slider 14 slides in the slide rail 13 until it is located above the ceramic body. Then the electric push cylinder 18 drives the base 171 to slide until it moves to the specified position, that is, when the two connecting frames 174 descend synchronously, one of the connecting frames 174 is located inside the ceramic body, and the other connecting frame 174 is located outside the ceramic body;

[0043] According to the qualified ceramic body contour scanned by the scanner included in the high-definition recorder 25, the position of each nozzle 177 is adjusted. During the specific setting, each micro-electric push rod 178 is independently controlled, and each micro-electric push rod 178 drives the hollow slide rod 176 to slide in a direction in the sleeve 175. During the sliding process, the hollow slide rod 176 drives the nozzle 177 to approach the inner and outer walls of the ceramic body until the position of each nozzle 177 is at the same distance from the inner and outer walls of the ceramic body. Then the electric lifting plate 26 drives the rectangular block 27 to move upward until the rectangular block 27 is inserted into the rectangular limiting groove 11. Then the motor 1 drives the rectangular block 27 to rotate. The rectangular block 27 drives the turntable 10 to rotate at a uniform speed through the rectangular limiting groove 11 and the rotating shaft 9. During the rotation, the turntable 10 drives the ceramic body to rotate at a uniform speed. At the same time, each independent nozzle 177 with the same spacing as the ceramic body sprays the inner and outer surfaces of the ceramic body with a consistent glaze thickness, thereby effectively solving the problem of inconsistent glaze thickness on the existing ceramic body during the glaze spraying process.

[0044] Embodiment 2: Figure 1 , Figure 5 and Figure 6 As shown, if the glaze is left standing for a long time, it is easy for the glaze to precipitate, which can easily lead to uneven glaze spraying on the surface of the ceramic body. To solve this problem, specific improvements are made as follows: a glaze stirring assembly 22 is provided on the top of the workbench 1, and the glaze stirring assembly 22 includes a barrel 221 and a directional sleeve 222. The barrel 221 is fixedly mounted on the top of the workbench 1, and the directional sleeve 222 is fixedly mounted on the top of the barrel 221. The directional sleeve 222 is connected to the barrel 221, and a piston rod 223 is slidably connected in the directional sleeve 222. A plurality of stirring discs 224 are provided in the barrel 221, and the stirring discs 224 are sleeved and fixed on the outside of the piston rod 223. A plurality of material passage holes 225 are provided in a circular array on the top of the stirring disc 224.

[0045] The top of the workbench 1 is fixedly connected to a frame, and the bottom of the frame is movably connected to an eccentric plate 226 through a bearing. The top of the piston rod 223 and the bottom of the eccentric plate 226 are fixedly connected to a positioning sleeve 227, and a ball head 228 is movably connected inside the positioning sleeve 227. A connecting rod 229 is fixedly connected between two corresponding ball heads 228, and a motor 2 for driving the eccentric plate 226 to rotate is fixedly installed on the top of the frame.

[0046] During the specific setting, the motor 2 drives the eccentric plate 226 to rotate, and the eccentric plate 226 drives the positioning sleeve 227 fixedly connected at the bottom to rotate synchronously, and drives the ball head 228 at the top of the piston rod 223 to rotate through the connecting rod 229 and the ball head 228 at the top. It should be noted that the centers of the eccentric plate 226 and the piston rod 223 are not on the same vertical center line. Only by staggering the center of the eccentric plate 226 and the center of the piston rod 223 can the eccentric plate 226 drive the piston rod 223 to slide back and forth along the directional sleeve 222 through the cooperation of the positioning sleeve 227, the connecting rod 229 and the ball head 228.

[0047] During the reciprocating sliding process, the piston rod 223 drives multiple stirring disks 224 to move reciprocally synchronously. A large number of material passing holes 225 are opened through the top of the stirring disk 224. The stirring disk 224 cooperates with the material passing holes 225 to oscillate and stir the liquid glaze inside the barrel 221, so that the glaze settled at the bottom of the barrel 221 floats up and is stirred again. By providing a stirring disk 224 that can slide back and forth, the glaze in the barrel 221 is always kept evenly dispersed and not settled, thereby further improving the glaze spraying effect on the ceramic body.
