[0029] Gear set 1 includes two synchronous gears 108 and two synchronous gear rings 109. The two synchronous gears 108 are rotatably mounted on the support ring plate 102 and the pressing ring plate 106 respectively. The two synchronous gears 108 are fixedly connected. The two synchronous gear rings 109 are fixedly mounted on the auxiliary circular plate 113 and the lower moving ring plate 135 in the support assembly respectively. The synchronous gears 108 are meshed with the corresponding synchronous gear rings 109 to form a gear pair. A synchronous motor 107 is fixedly mounted on the pressing ring plate 106, and the output shaft of the synchronous motor 107 is fixedly connected to the corresponding synchronous gear 108.

[0030] The pressing ring plate 106 is located directly above the supporting ring plate 102, that is, the pressing assembly is located directly above the supporting assembly. The downward motor 137 is started, and the downward pulley 136 rotates under the action of the downward belt 138. Under the action of the downward screw rod 134, the auxiliary circular plate 113 in the pressing assembly moves up and down relative to the base frame 101. The synchronous motor 107 is started to drive the corresponding synchronous gear 108 to rotate, and the two synchronous gears 108 rotate synchronously, thereby causing the two synchronous gear rings 109 to rotate synchronously, so that the auxiliary circular plate 113 in the supporting assembly and the downward ring plate 135 rotate synchronously, and the two auxiliary circular plates 113 rotate synchronously.

[0031] Auxiliary circular blocks 118 are fixedly provided on the auxiliary circular plates 113, and supporting circular rods 123 are fixedly installed on the auxiliary circular plates 113. The auxiliary circular blocks 118 are fixedly installed on the ends of the supporting circular rods 123 farthest from the auxiliary circular plates 113. An annular support plate 110 is slidably installed on the auxiliary circular plates 113, and a yielding screw rod 114 is fixedly installed on the annular support plate 110. A yielding pulley 115 and a transmission pulley 117 are rotatably installed on the auxiliary circular plates 113, and a transmission belt 116 is arranged between the yielding pulley 115 and the transmission pulley 117. The yielding pulley 115 and the corresponding yielding screw rod 114 form a spiral pair. A yielding motor 124 is also fixedly installed on the auxiliary circular plate 113, and the output shaft of the yielding motor 124 is fixedly connected to the corresponding transmission pulley 117.

[0032] The yielding motor 124 is started to drive the corresponding drive pulley 117 to rotate. Under the action of the drive belt 116, the yielding pulley 115 rotates synchronously, and then under the action of the yielding screw rod 114, the annular support plate 110 moves up and down relative to the auxiliary circular plate 113.

[0033] A plurality of auxiliary ring plates 119 are evenly arranged between the auxiliary circular block 118 and the corresponding annular support plate 110. The plurality of auxiliary ring plates 119 are sequentially arranged between the annular support plate 110 and the auxiliary circular block 118. The difference in the inner and outer circle radius of each auxiliary ring plate 119 is equal. When the annular support plate 110 and the upper surfaces of the corresponding auxiliary circular block 118 and the auxiliary ring plate 119 are in the same plane, a complete circular plate is formed. The auxiliary ring plates 119 are provided with step surfaces. The step surfaces on the auxiliary ring plates 119 are used to limit the position between the auxiliary circular block 118 and the auxiliary ring plate 119. The axes of the annular support plate 110, the auxiliary circular plate 113, the auxiliary circular block 118 and the auxiliary ring plate 119 are in the same straight line.

[0034] A distance-adjusting slider 129 is symmetrically slidably installed on the auxiliary circular plate 113, and a tension spring is arranged between the distance-adjusting slider 129 and the auxiliary circular plate 113. One end of the tension spring is fixedly connected to the auxiliary circular plate 113, and the other end of the tension spring is fixedly connected to the corresponding distance-adjusting slider 129. A supporting long rod 120 is fixedly arranged on the distance-adjusting slider 129, and the supporting long rod 120 is used to limit the position of the auxiliary ring plate 119. A distance-adjusting ring plate 127 is also rotatably installed on the auxiliary circular plate 113, and two arc-shaped strip plates 128 are fixedly arranged in a circular array on the distance-adjusting ring plate 127, and the arc-shaped strip plates 128 are used to push the corresponding supporting long rods 120 to move.

[0035] In the initial position, the tension springs between the distance adjusting slider 129 and the auxiliary circular plate 113 are not stretched. At this time, the two distance adjusting sliders 129 on the same auxiliary circular plate 113 are located at the farthest positions, that is, the corresponding two supporting long rods 120 are located at the farthest positions. At this time, the end surface of the supporting long rod 120 farthest from the corresponding auxiliary circular plate 113 contacts the surface of the auxiliary ring plate 119 farthest from the axis of the annular support plate 110. Under the action of the supporting long rod 120, the auxiliary ring plate 119 cannot move relative to the auxiliary circular block 118. Under the action of the step surface on the auxiliary ring plate 119, all auxiliary ring plates 119 cannot move relative to the auxiliary circular block 118.

[0036] The distance adjusting ring plate 127 is driven to rotate, and the two arc strip plates 128 on the distance adjusting ring plate 127 rotate synchronously. Under the action of the arc strip plates 128, the two supporting long rods 120 move toward each other, and the two distance adjusting sliders 129 move toward each other. The tension spring between the distance adjusting slider 129 and the auxiliary circular plate 113 is stretched, and then the supporting long rod 120 moves to the end face of the supporting long rod 120 farthest from the auxiliary circular plate 113 and the end face of the supporting long rod 120 farthest from the axis of the auxiliary circular block 118. The auxiliary ring plate 119 contacts with the auxiliary ring plate 119, at this time, the auxiliary ring plate 119 farthest from the axis of the auxiliary circular block 118 can move relative to the other auxiliary ring plates 119, and at this time, the auxiliary ring plate 119 on the inner side of the auxiliary ring plate 119 that is the second farthest from the axis of the auxiliary circular block 118 cannot move relative to the auxiliary circular block 118, and the end face of the supporting long rod 120 farthest from the auxiliary circular plate 113 contacts with the surface of the auxiliary circular block 118, at this time, the auxiliary ring plates 119 can all move relative to the auxiliary circular block 118.

[0037] A snap-on slide plate 133 is symmetrically slidably installed on the annular support plate 110, and sliding grooves cooperating with the snap-on slide plate 133 are symmetrically arranged on the auxiliary ring plate 119. A distance-adjusting slide plate 122 is symmetrically slidably installed on the auxiliary circular plate 113. Springs are arranged between the distance-adjusting slide plates 122 and the auxiliary circular plate 113. A linkage strip plate 121 is fixedly installed on the snap-on slide plate 133, and the linkage strip plate 121 slides with the corresponding distance-adjusting slide plate 122. Two arc strip plates 126 are fixedly arranged in a circular array on the distance-adjusting ring plate 127, and distance-adjusting short columns 125 are fixedly arranged on the distance-adjusting slide plates 122. The arc strip plates 126 are used to push the corresponding distance-adjusting short columns 125 to move.

[0038] In the initial position, the springs between the distance adjusting slide 122 and the auxiliary circular plate 113 are not compressed, and the two distance adjusting slides 122 are located at the farthest positions. Under the action of the linkage strip 121, the two clamping slides 133 are located at the farthest positions. At this time, the clamping slides 133 are not in contact with the auxiliary ring plate 119.

[0039] When the distance adjusting ring plate 127 rotates, the two arc strips 126 also rotate synchronously. Under the action of the distance adjusting short column 125, the two distance adjusting slides 122 move toward each other. The spring between the distance adjusting slide 122 and the auxiliary circular plate 113 is compressed. Then, under the action of the linkage strip 121, the two clamping slides 133 move toward each other. When the end face of the supporting long rod 120 farthest from the auxiliary circular plate 113 contacts the auxiliary ring plate 119 farthest from the axis of the auxiliary circular block 118, the clamping slide The plate 133 engages with the slide groove on the auxiliary ring plate 119 which is farthest from the axis of the auxiliary circular block 118. At this time, the annular support plate 110 is driven to move toward the direction close to the corresponding auxiliary circular plate 113. Under the action of the clamping slide 133, the auxiliary ring plate 119 which is farthest from the axis of the auxiliary circular block 118 moves synchronously. There is friction between the clamping slide 133 and the auxiliary ring plate 119. Therefore, the auxiliary ring plate 119 and the annular support plate 110 move synchronously, and the auxiliary ring plate 119 will not move relative to the clamping slide 133.

[0040] That is, when the position of the supporting long rod 120 is adjusted, the position of the clamping slide 133 changes synchronously. When the supporting long rod 120 contacts the auxiliary round block 118, the clamping slide 133 engages with the sliding grooves on all the auxiliary ring plates 119 corresponding to the clamping slide 133. Under the action of the clamping slide 133, when the annular support plate 110 moves, the auxiliary ring plates 119 corresponding to the annular support plate 110 all move synchronously.

[0041] When the annular support plate 110 moves relative to the auxiliary circular plate 113 , the linkage strip plate 121 slides relative to the corresponding distance-adjusting slide plate 122 .

[0042] A pitch-adjusting gear ring 130 is fixedly mounted on the pitch-adjusting ring plate 127, and a pitch-adjusting motor 132 is also fixedly mounted on the auxiliary circular plate 113. A pitch-adjusting gear 131 is fixedly mounted on the output shaft of the pitch-adjusting motor 132. The pitch-adjusting gear 131 meshes with the corresponding pitch-adjusting gear ring 130 to form a gear pair. When the pitch-adjusting motor 132 is started to drive the pitch-adjusting gear 131 to rotate, the pitch-adjusting gear ring 130 rotates, and the pitch-adjusting ring plate 127 corresponding to the pitch-adjusting gear ring 130 rotates synchronously, thereby causing the two arc-shaped strip plates 1 126 and the two arc-shaped strip plates 2 128 on the pitch-adjusting ring plate 127 to rotate synchronously.

[0043] A positioning assembly is provided on the base frame 101, and the positioning assembly includes a positioning ring plate 103, the positioning ring plate 103 is slidably installed on the base frame 101, a positioning screw rod 105 is rotatably installed on the base frame 101, a positioning motor 104 is fixedly installed on the base frame 101, the output shaft of the positioning motor 104 and the positioning screw rod 105 are fixedly connected, the positioning screw rod 105 and the positioning ring plate 103 form a spiral pair, the axes of the supporting ring plate 102 and the positioning ring plate 103 are in the same straight line, three positioning strips 111 are movably provided in a circular array on the positioning ring plate 103, the positioning strips 111 are used to adjust the position of the ceramic, and a nozzle 146 is also provided on the positioning ring plate 103.

[0044] Three adjusting racks 112 are slidably installed in a circular array on the adjusting ring plate 103, and the adjusting strip plates 111 are respectively fixedly installed on the ends of the corresponding adjusting racks 112 that are closest to the axis of the adjusting ring plate 103. A gear set 2 is arranged between the three adjusting racks 112, and the gear set 2 includes a centering gear ring 142, three centering gears 140, and three driven gears 141. The three centering gears 140 are rotatably installed on the adjusting ring plate 103 in a circular array, and the driven gears 141 are fixedly installed on the corresponding centering gears 140. The centering gears 140 and the corresponding adjusting racks 112 are meshed to form a gear rack pair. The centering gear ring 142 is rotatably installed on the adjusting ring plate 103, and the driven gears 141 are all meshed with the centering gear ring 142 to form a gear pair. A centering motor 139 is also fixedly installed on the adjusting ring plate 103, and the output shaft of the centering motor 139 is fixedly connected to the corresponding centering gear 140.

[0045] In the initial position, the adjustment ring plate 103 is located at the position closest to the support ring plate 102, and the annular support plate 110 corresponding to the support ring plate 102 is located at the position closest to the pressing ring plate 106. At this time, the upper surfaces of the annular support plate 110, the auxiliary round block 118, and the auxiliary ring plate 119 in the support assembly are on the same plane, and the upper surface of the centering gear ring 142 is located below the plane, so as to facilitate the placement of the ceramics to be sprayed on the plane.

[0046] In the initial position, the three adjusting strips 111 are all located at the position farthest from the axis of the centering gear ring 142. At this time, the adjusting strips 111 are all located on the outside of the annular support plate 110, that is, the adjusting strips 111 will not affect the movement of the annular support plate 110. The centering motor 139 is started to drive the corresponding centering gear 140 to rotate, and the driven gear 141 on the centering gear 140 rotates synchronously. Under the action of the centering gear ring 142, the three centering gears 140 and the three driven gears 141 rotate synchronously, that is, the adjusting rack 112 moves toward the direction close to the axis of the adjusting ring plate 103, and then the three adjusting strips 111 move synchronously toward the direction close to the axis of the adjusting ring plate 103.

[0047] When the downward moving ring plate 135 is located at the farthest position from the supporting ring plate 102 and the two annular support plates 110 are located at the closest position to each other, the distance between the two annular support plates 110 and the length of the adjusting strip plate 111 are equal.

[0048] When the lower ring plate 135 is at the farthest position from the support ring plate 102 and the two annular support plates 110 are at the farthest position from each other, the ceramic to be sprayed is placed on the plane formed by the annular support plate 110, the auxiliary round block 118 and the auxiliary ring plate 119 in the support assembly, and then the positioning motor 104 is started to drive the positioning screw 105 to rotate, so that the positioning ring plate 103 moves upward, that is, the positioning strips 111 are all moved upward, so that the upper end surface of the positioning strips 111 and the ring in the pressing assembly are The lower surfaces of the shaped support plates 110 are in the same plane. At this time, the lower end surfaces of the adjusting strips 111 and the upper surfaces of the annular support plates 110 in the support assembly are in the same plane. Then the centering motor 139 is started to move the three adjusting strips 111 toward the direction close to the axis of the adjusting ring plate 103. Under the action of the three adjusting strips 111, the position of the ceramic on the support assembly is adjusted, and finally the center line of the ceramic and the axis of the annular support plate 110 are in the same straight line, thereby realizing the adjustment of the ceramic position.

[0049] A feed screw 143 is also slidably mounted on the positioning ring plate 103, and a feed slide 145 is rotatably mounted on the positioning ring plate 103. The end of the feed screw 143 farthest from the axis of the positioning ring plate 103 forms a spiral pair with the feed slide 145. A feed motor 144 is fixedly mounted on the positioning ring plate 103, and the output shaft of the feed motor 144 is fixedly connected to the feed slide 145. The nozzle 146 is fixedly mounted on the end of the feed screw 143 closest to the axis of the positioning ring plate 103.

[0050] In the initial position, the feed screw 143 is located at the farthest position from the axis of the positioning ring plate 103, that is, the nozzle 146 is located at the farthest position from the axis of the positioning ring plate 103, and the nozzle 146 is located on the outside of the annular support plate 110. The feed motor 144 is started to drive the feed slide 145 to rotate, so that the feed slide 145 moves toward the direction close to the axis of the positioning ring plate 103, and the nozzle 146 moves synchronously toward the direction close to the axis of the positioning ring plate 103.

[0051] After the positioning strip 111 completes the position adjustment of the ceramic on the support assembly, the feed motor 144 is started to move the nozzle 146 toward the ceramic, and the ceramic surface is sprayed through the nozzle 146. The positioning motor 104 is started to adjust the position of the nozzle 146 relative to the ceramic, and the two auxiliary circular plates 113 are rotated synchronously to achieve complete spraying of the ceramic surface.

[0052] Working principle: Place the ceramic to be sprayed on the supporting plane formed by the annular supporting plate 110, the auxiliary round block 118 and the auxiliary ring plate 119 in the supporting assembly, then start the positioning motor 104 to adjust the position of the positioning strip 111, and then start the centering motor 139 to make the three positioning strips 111 move toward the direction close to the axis of the centering gear ring 142. Under the action of the three positioning strips 111, the position of the ceramic is adjusted.

[0053] Then, according to the minimum diameter of the inner side of the ceramic, the distance adjusting motor 132 is started to drive the distance adjusting ring plate 127 to rotate, and under the action of the arc strip plate 2 128 and the distance adjusting slider 129, the lower end surface of the supporting long rod 120 in the pressing assembly contacts the auxiliary ring plate 119 which is slightly smaller than the minimum diameter of the inner side of the ceramic, and under the action of the linkage strip plate 121, the distance adjusting slide plate 122, the distance adjusting short column 125, and the arc strip plate 1 126, the clamping slide plate 133 engages with the sliding groove on the other auxiliary ring plate 119 located on the outside of the auxiliary ring plate 119.

[0054] Then start the yielding motor 124 in the pressing assembly to move the annular support plate 110 in the pressing assembly upward. Under the action of the auxiliary circular plate 113, the auxiliary ring plate 119 that is larger than the minimum diameter of the inner side of the ceramic moves upward synchronously, and finally the annular support plate 110 moves to the position farthest from the support ring plate 102. Then start the downward movement motor 137 to move the auxiliary circular plate 113 and the downward movement screw rod 134 in the pressing assembly downward synchronously, that is, the auxiliary circular block 118 in the pressing assembly moves downward synchronously, and the auxiliary ring plate 119 on the same plane as the auxiliary circular block 118 moves downward synchronously, that is, the auxiliary circular block 118 and this part of the auxiliary ring plate 119 move to the inside of the ceramic through the position of the minimum diameter of the ceramic, and finally the lower surfaces of the auxiliary circular block 118 and this part of the auxiliary ring plate 119 contact the inner bottom surface of the ceramic, that is, under the action of the pressing assembly, the ceramic is fixed, and then the three adjustment strips 111 move to the position farthest from the axis of the centering gear ring 142.

[0055] At this time, the ceramic is in a fixed state, and then according to the diameter of the lower bottom surface of the ceramic, the distance adjusting motor 132 is started to drive the distance adjusting ring plate 127 to rotate, and under the action of the arc strip plate 2 128 and the distance adjusting slider 129, the upper end surface of the supporting long rod 120 in the supporting assembly contacts the auxiliary ring plate 119 which is farthest from the axis of the auxiliary round block 118 and is in contact with the ceramic, and under the action of the linkage strip plate 121, the distance adjusting slide plate 122, the distance adjusting short column 125, and the arc strip plate 1 126, the clamping slide plate 133 engages with the sliding grooves on the other auxiliary ring plates 119 located outside the auxiliary ring plate 119, and then the yielding motor 124 in the supporting assembly is started, so that the annular support plate 110 in the supporting assembly moves downward, and the auxiliary ring plates 119 engaged by the clamping slide plate 133 all move downward synchronously, and finally the annular support plate 110 and this part of the auxiliary ring plate 119 move to the position farthest from the pressing ring plate 106.

[0056] At this time, the annular support plate 110 and the unused auxiliary ring plate 119 in the support assembly and the pressing assembly make way for the nozzle 146 to spray the ceramic, thereby facilitating the nozzle 146 to spray the ceramic surface.

[0057] And start the synchronous motor 107, that is, the two auxiliary circular plates 113 rotate, and then the two auxiliary round blocks 118 rotate synchronously, that is, the ceramic rotates relative to the nozzle 146, and then start the feed motor 144 and the positioning motor 104 to adjust the position of the nozzle 146, under the action of the nozzle 146, the spraying of the ceramic surface pattern is completed.

[0058] After the spraying is completed, the above steps are performed in reverse order to release the pressing assembly from fixing the ceramic.

[0059] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
