[0045] Embodiment:

[0046] As shown in Figure 1 and Figure 2 , a glazing device for ceramic vases comprises:

[0047] a frame 1;

[0048] a rotating assembly 2, two sets of the rotating assembly 2 are installed on the frame 1, each set of the rotating assembly 2 comprises a spindle unit 21 and a power unit 22 driving the spindle unit 21 to rotate;

[0049] a fixing assembly 3, the fixing assembly 3 comprises a positioning unit 31 arranged on a set of the spindle unit 21 for supporting a vase 100 and a suction cup unit 32 arranged in the corresponding spindle unit 21 and capable of adsorbing the vase 100; and

[0050] a glazing assembly 4, the glazing assembly 4 comprises a linear slide unit 41 arranged on another set of the spindle unit 21, a vertical column 42 arranged on the linear slide unit 41, a plurality of sets of horizontal moving units 43 arranged on the vertical column 42 in an up-down array and capable of being horizontally slidably arranged, and a limiting unit 44 arranged on the vertical column 42 for limiting the movement of the horizontal moving units 43;

[0051] an end of the horizontal moving unit 43 is arranged in contact with the vase 100, which comprises two sets of moving rods 431 arranged in the rotation direction of the vase 100, and brush heads 432 and glazing ports 433 arranged at the ends of the moving rods 431 and arranged in front of and behind the vase 100 in the rotation direction of the vase 100, the brush heads 432 being arranged in contact with the vase 100;

[0052] a plurality of sets of the brush heads 432 are in contact with the outer surface of the vase 100, a plurality of sets of the glazing ports 433 form a shape consistent with the shape of the vase 100, the limiting unit 44 allows the shape to be maintained, the vase 100 rotates, a plurality of sets of the brush heads 432 clean the body of the vase, then the glazing assembly 4 rotates, a plurality of sets of the brush heads 432 disengage from the body of the vase, and then a plurality of sets of the glazing ports 433 glaze the body of the vase.

[0053] It should be noted that in actual production, the upper part of the frame 1 is provided with a closable cover (not shown in the figure), which is equipped with a dust collection device (not shown in the figure) inside, so that the glaze does not fly during the glazing process.

[0054] More specifically, the moving rod 431 is T-shaped in cross-section, and the upright column 42 is provided with a T-shaped groove that cooperates with the moving rod 431.

[0055] Further, as shown in Figure 3 , Figure 5 and Figure 7 , the spindle unit 21 includes a mounting seat 211 mounted on the frame 1, two sets of tapered roller bearings 212 arranged at the bottom of the mounting seat 211 and the frame 1, bearing pressure rings 213 respectively arranged at the bottom of the mounting seat 211 and the frame 1 and in contact with the outer rings of the tapered roller bearings 212, a hollow spindle 214 passing through the two sets of tapered roller bearings 212, a compression ring 215 arranged on the hollow spindle 214 and in contact with the inner ring of the upper tapered roller bearing 212, and a locking nut 216 threadedly arranged on the hollow spindle 214 and in contact with the inner ring of the lower tapered roller bearing 212.

[0056] It should be noted that the tapered roller bearings 212 are arranged to make the rotation of the hollow spindle 214 more stable, so that when the vase 100 rotates with the hollow spindle 214, the vase 100 also rotates more stably.

[0057] More specifically, the lengths of the hollow spindles 214 in the two sets of spindle units 21 are the same, only the lengths of the frame 1 are different.

[0058] It is worth mentioning that, as shown in Figure 8 , the hollow spindle 214 is sleeved with a sheath 1001, one end of which is mounted on the frame 1, and the other end is in rotational sealing connection with the hollow spindle 214, which can effectively prevent the glaze from entering the bearing.

[0059] Further, as shown in Figure 2 , the power unit 22 includes a motor mounting bracket 221 arranged at the bottom of the frame 1, a motor 222 arranged on the motor mounting bracket 221, a driven gear 223 fixed coaxially with the hollow spindle 214, and a driving gear 224 mounted on the power output shaft of the motor 222 and in meshing arrangement with the driven gear 223.

[0060] It should be noted that the motor 222 is a Mitsubishi brand servo motor, so that the motor 222 drives the rotation number and rotation angle of the hollow spindle 214 is more accurate, thereby improving the overall glaze efficiency of the vase 100.

[0061] More needs to be explained that the number of teeth of the driving gear 224 is less than the number of teeth of the driven gear 223, so that the torque of the driven gear 223 is increased, so that the hollow spindle 214 can be more easily rotated, and because the vase 100 requires less number of rotations, the speed reduction caused by torque amplification has negligible effect on the actual paint efficiency.

[0062] Further, as shown in Figure 4 The positioning unit 31 includes a circular plate 311 disposed on the hollow spindle 214 and a positioning ring 312 detachably disposed on the circular plate 311.

[0063] It should be noted that the positioning ring 312 is used for positioning the bottom of the vase 100, and the positioning ring 312 can be replaced, so that the positioning ring 312 can be replaced, and the vase 100 with different specifications can be used.

[0064] Further, as shown in Figure 7 The suction cup unit 32 includes a suction cup seat 321 disposed at an intermediate position of the hollow spindle 214 and a suction cup 322 disposed above the suction cup seat 321 and compressibly disposed, the upper surface of the suction cup 322 protruding the surface of the positioning ring 312.

[0065] It should be noted that the part of the suction cup 322 protruding the upper surface of the positioning ring 312 is made of rubber material, and the vase 100 is placed on the top of the suction cup 322, and the bottom of the vase 100 is in full contact with the suction cup 322, thereby ensuring the firmness of the suction cup 322 adsorbing the vase 100.

[0066] More needs to be explained that the feeding process of the vase 100 to the positioning ring 312 can be completed by manual or mechanical hand.

[0067] Further, the brush head 432 is aligned with the radial direction of the positioning ring 312 along the advancing direction of the moving rod 431.

[0068] It should be noted that the end of the brush head 432 is made of flexible material, and the brush head 432 is in closer contact with the vase 100 and covers a larger area.

[0069] It should be noted that the moving rod 431 used to install the brush head 432 is longer than the moving rod 431 used to install the glaze spray nozzle 433, thereby ensuring that the glaze spray nozzle 433 and the body of the vase 100 are always kept at the optimal distance during glazing.

[0070] It is also necessary to explain that, such as Figure 12 As shown, when the brush head 432 comes into contact with the vase 100, the glaze spray nozzle 433 is arranged parallel to the radial line of the vase 100.

[0071] It is worth mentioning that after the brush head 432 finishes cleaning the vase 100, the hollow main shaft 214 rotates at a certain angle, causing the brush head 432 to disengage from the vase 100. At this time, the spraying direction of the glaze nozzle 433 is parallel to the radial direction of the vase 100. Maintaining this spraying direction allows the glaze to adhere better to the body of the vase 100.

[0072] It should be noted that the glazing nozzle 433 is connected to an external glazing supply device, and each set of glazing nozzles 433 can be used for glazing independently.

[0073] Furthermore, such as Figure 4 As shown, the linear slide unit 41 includes a base plate 411 mounted on the hollow main shaft 214, a movable plate 412 slidably mounted on the base plate 411 via two sets of guide rail sliders, and a cylinder a413 mounted on the base plate 411 with its power output end connected to the movable plate 412; the column 42 is mounted on the movable plate 412.

[0074] It should be noted that the cylinder a413 is a rodless cylinder, which further saves space.

[0075] Furthermore, the transverse unit 43 also includes a connecting plate 434 connecting the ends of the two sets of moving rods 431 and a spring a435 disposed between the connecting plate 434 and the column 42.

[0076] It should be noted that the cylinder a413 drives the base plate 411 to move, the brush head 432 abuts against the vase 100, the moving rod 431 will move accordingly, and the spring a435 will deform accordingly.

[0077] Further, the limiting unit 44 comprises a long slot 441 vertically arranged in the stand 42, a limiting rod 442 slidingly arranged in the long slot 441, a cylinder mounting base 443 arranged at the top of the stand 42, a cylinder b 444 mounted on the cylinder mounting base 443 and having a power output end connected with the limiting rod 442, and a limiting piece 445 connected with the limiting rod 442 and abutting against the moving rod 431.

[0078] Further, the limiting piece 445 comprises a circular hole 4451 horizontally arranged on the stand 42, a containing groove 4452 coaxially arranged at the middle position of the circular hole 4451 and communicating with the circular hole 4451, an abutting rod 4453 slidingly arranged in the circular hole 4451 and having an outer end abutting against the moving rod 431, an abutting cavity 4454 arranged on the limiting rod 442 and used for containing the inner end of the abutting rod 4453, a limiting plate 4455 coaxially arranged outside the abutting rod 4453 and located in the containing groove 4452, and a spring b 4456 sleeved outside the abutting rod 4453 and connecting the limiting plate 4455 and the end face of the containing groove 4452, the bottom face of the abutting cavity 4454 is arranged in a slope and is in transition connection with the side face of the limiting rod 442, and the bottom face of the abutting cavity 4454 is abutting against the inner end of the moving rod 431.

[0079] It should be noted that, as shown in Figure 8 and Figure 9 , after the bottom plate 411 is moved to the position, the cylinder b 444 drives the limiting rod 442 to move downward, the abutting rod 4453 moves along the bottom face of the abutting cavity 4454, thereby driving the outer end of the abutting rod 4453 to abut against the moving rod 431, and the moving rod 431 is fixed at this position; after the bottom plate 411 is reset, the cylinder b 444 drives the limiting rod 442 to move upward, the abutting rod 4453 moves along the bottom face of the abutting cavity 4454, the outer end of the abutting rod 4453 is disengaged from the moving rod 431 under the action of the spring b 4456, and the two groups of moving rods 431 are reset under the action of the spring a 435.

[0080] It should be further noted that, as shown in Figure 10 to Figure 12 , the cleaning process of the brush head 432 and the glaze spraying process of the glaze spraying port 433 are both performed on the premise that the moving rod 431 is fixed by the limiting piece 445.

[0081] Working process:

[0082] The artificial or mechanical hand places the vase 100 on the positioning ring 312, the suction cup unit 32 is adsorbed with the bottom of the vase 100, the air cylinder a 413 drives the bottom plate 411 to move, the brush head 432 is in contact with the vase 100, the moving rod 431 generates corresponding movement, the spring a 435 generates corresponding deformation, a plurality of groups of the glaze spraying port 433 form a contour consistent with the outer contour of the vase 100, the air cylinder b 444 drives the limiting rod 442 to move downward, the contact rod 4453 moves along the bottom surface of the contact cavity 4454, thereby driving the outer side end of the contact rod 4453 to contact with the moving rod 431, the moving rod 431 is fixed, the glaze spraying port 433 and the brush head 432 remain fixed, then the motor 222 corresponding to the vase 100 rotates and drives the corresponding hollow spindle 214 to rotate, the vase 100 rotates, the brush head 432 cleans the vase 100, then the vase 100 stops rotating, the motor 222 corresponding to the bottom plate 411 rotates and drives the corresponding hollow spindle 214 to rotate, the brush head 432 is disengaged from the vase 100, the spraying direction of the glaze spraying port 433 is rotated to form an acute angle with the tangent direction of the vase 100, then the vase 100 rotates again, a plurality of groups of the glaze spraying port 433 spray glaze on the vase 100, after the glaze spraying is completed, the corresponding motor 222 drives the bottom plate 411 to rotate and reset, the air cylinder a 413 and the air cylinder b 444 reset, the brush head 432 and the glaze spraying port 433 reset.
