Description

Technical Field

[0001] This invention relates to the field of ceramic glazing technology, specifically to a glazing device and process for ceramic handicrafts. Background Technology

[0002] In porcelain production, glazing is mainly used to apply glaze to form a surface coating. Its core functions include achieving a uniform and controllable glaze layer and improving the physical properties and decorative effects of porcelain.

[0003] Currently, spray glazing is mostly used for large ceramic products, complex shapes, or thin-walled objects. A thicker glaze layer is obtained through multiple sprays. However, there are certain drawbacks in the current spray glazing process. After the glaze mist is sprayed, the airflow around the porcelain will cause the glaze mist to form eddies. The thickness of the glaze mist particles that accumulate after the eddies adheres to the surface of the porcelain body will become uncontrollable. In severe cases, it can cause spots, bubbles, and uneven glaze thickness on the surface of the porcelain body.

[0019] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0020] 1. This invention, by installing a glaze storage mechanism on a supporting and fixing mechanism and using two sets of porcelain clamping mechanisms, can fix and clamp porcelain with complex structures. After the porcelain is located at the center of the two outer shells, the glaze is input along the closed outer shells. Finally, the nozzle can always spray directly perpendicular to the porcelain blank. After the uniformly rotating inner ring pad is rotated, the sprayed glaze mist will be continuously and evenly sprayed on the surface of the porcelain, thereby avoiding the problem of uneven glaze layer thickness caused by insufficient continuity of glaze mist spraying.

[0021] 2. By installing an exhaust pipe on the sliding frame, the air in the central area of ​​the two outer shells is continuously and continuously output to the outside through the external hose. The glaze mist that diffuses around the porcelain body is forcibly absorbed, so that the glaze mist maintains a constant arc-shaped state along the flow direction of the spray on the porcelain surface. This further avoids the problem of excessive glaze mist around the porcelain, which would cause orange peel or spots on the glaze layer.

[0022] 3. This invention uses an arc-shaped guide plate fixedly installed on the back of the inner ring pad. With the regular rotation of the inner ring pad along the inner sides of the two outer shells, the arc-shaped guide plate, which rotates synchronously with the inner ring pad, can enhance the flowability of the glaze passing through the inner cavities of the two outer shells. In addition, the amount of glaze sprayed can be controlled by adjusting the distance between the pressure filter pad and the nozzle. This can prevent glaze bubbles from forming on the porcelain blank due to interference from air bubbles or air in the glaze. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0039] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0040] The following describes, with reference to the accompanying drawings, some embodiments of a glazing device and process for ceramic handicrafts provided by the present invention.

[0041] Example 1:

[0042] Combination Figures 1 to 10 As shown, the present invention provides a glazing device and process for ceramic handicrafts, including a support and fixing mechanism 100, a glaze storage mechanism 300 installed on the support and fixing mechanism 100, two sets of porcelain clamping mechanisms 200 movably installed in the support and fixing mechanism 100, and a glazing adjustment mechanism 400 installed in the glaze storage mechanism 300. The support and fixing mechanism 100 is used to provide a support platform for the glaze storage mechanism 300, the two sets of porcelain clamping mechanisms 200 are used to fit and clamp the porcelain blanks, and the glazing adjustment mechanism 400 is used to enhance the fluidity of the glaze and improve the fluidity of the glaze.

[0043] The load-bearing fixing mechanism 100 includes a load-bearing base 110, and multiple first studs 1101 are fixedly installed on the load-bearing base 110. Two side guard plates 120 are fixedly installed on the load-bearing base 110. Springs 130 are fixedly installed on the inner wall of the side guard plates 120. Four symmetrically distributed pads 1102 are fixedly installed on both sides of the load-bearing base 110. Pre-installed holes are opened inside the pads 1102. A slot is opened in the plate end of the load-bearing base 110, and a horizontally placed first bidirectional lead screw 140 is movably installed in the slot. An end plate 150 is threaded on the first bidirectional lead screw 140. Two symmetrically distributed lever arms 1501 are movably installed in the end plate 150, and a clamp 1502 is movably connected to each of the two lever arms 1501. A horizontal groove is opened on the front of the side guard plate 120, and the clamp 1502 is adapted to be parallel to the horizontal groove.

[0044] Two sets of porcelain clamping mechanisms 200 are respectively movably installed in the two side guard plates 120, and the two sets of porcelain clamping mechanisms 200 are used to adapt and clamp and fix porcelain blanks with complex structures.

[0045] The glaze storage mechanism 300 includes four bases 330 mounted on a plurality of first studs 1101. Two bases 330 are equipped with first housings 310, and the other two bases 330 are equipped with second housings 320. Cover plates 350 are fixedly mounted on both the first housings 310 and the second housings 320. Guide tubes 370 are installed inside the two cover plates 350. Insert plates 340 are fixedly mounted on the bottom of both the first housings 310 and the second housings 320. The insert plates 340 have an L-shaped cross-section. Buckle plates 360 are snapped onto the outside of the two insert plates 340.

[0046] The glazing adjustment mechanism 400 includes an inner ring gasket 410 movably installed inside the first housing 310 and the second housing 320. An arc-shaped guide plate 430 is fixedly installed on the back of the inner ring gasket 410. A spray pipe 440 is installed in the middle of the arc-shaped guide plate 430. A nozzle 4401 is installed in the pipe section of the spray pipe 440. Two second studs 3101 are fixedly installed on the first housing 310, and a housing 380 is fixedly installed on the two second studs 3101. A motor 3801 is fixedly installed inside the housing 380, and a gear 3802 is installed on the motor 3801.

[0047] The inner ring pad 410 extends through to the plate end inside the first housing 310 and a ring gear 420 is fixedly installed thereon, and the gear 3802 is adapted to mesh with the ring gear 420.

[0048] In use, a sealing rubber gasket is added to the interface between the first housing 310 and the second housing 320 beforehand. Then, the two plug plates 340 are snapped together and fixed using the buckle plate 360. The fixed first housing 310 and the second housing 320 can provide an effective and safe transfer path for the glaze.

[0049] Next, the client starts the motor 3801 until the motor 3801, in conjunction with the gear 3802, drives the ring gear 420 and the inner ring pad 410. Finally, the rotating inner ring pad 410 carries the arc-shaped guide plate 430 and the nozzle 440 to rotate at a constant speed along the inner side of the first outer shell 310 and the second outer shell 320. The uniformly rotating nozzle 440 and the nozzle 4401 spray the glaze vertically onto the surface of the porcelain blank. The radially sprayed glaze mist reduces the interference of the surrounding airflow. With the help of the sprayed glaze mist jet, the glaze mist is evenly sprayed onto the outer surface of the porcelain blank.

[0050] The base 330 is inserted into the outside of two adjacent first studs 1101, and the base 330 is fixed to the two first studs 1101 by two nuts.

[0051] Example 2:

[0052] Combination Figure 3 and Figure 4As shown, based on Embodiment 1, the porcelain clamping mechanism 200 includes a sliding frame 210 movably installed within the side guard plate 120, an exhaust pipe 220 movably installed within the sliding frame 210, a bolt 2103 threadedly installed within the sliding frame 210 to press the exhaust pipe 220, a washer 2101 fixedly installed on the rod section of the sliding frame 210, a support rod 2102 fixedly installed at the bottom end of the sliding frame 210, and an external flexible hose 2201 installed at the outer end of the exhaust pipe 220. A filter 2202 is installed in the arc-shaped groove at the inner end of the exhaust pipe 220. Two symmetrically distributed outer shells 230 are installed on the rectangular end of the top of the sliding frame 210. A hexagonal threaded sleeve 2301 is movably installed inside the two outer shells 230. An extension screw 240 is installed in the internal thread of the hexagonal threaded sleeve 2301. Two limiting rods 2401 are fixedly installed on the column head at the inner end of the extension screw 240. The two limiting rods 2401 are respectively inserted into the holes inside the two outer shells 230.

[0053] The end of the support rod 2102 is fixedly installed inside the clamp 1502;

[0054] An anti-detachment pad 250 is fixedly installed on the post head at the inner end of the extended screw 240.

[0055] Preferably, the bottom plate of the sliding frame 210 has a rectangular structure, and a sleeve is provided on the columnar rod section of the sliding frame 210. The exhaust pipe 220 is movably installed inside the sleeve. According to the actual size of the porcelain blank, the first bidirectional lead screw 140 is pre-rotated until the end plate 150 carries the two lever arms 1501 and the two clamps 1502 to extend relative to each other. Finally, the two sets of porcelain clamping mechanisms 200 pulled by the two clamps 1502 will quickly clamp and fix porcelain blanks with different structures.

[0056] The semi-circular plate segments at the inner ends of the two exhaust pipes 220 are located directly below the inner sides of the first outer shell 310 and the second outer shell 320. They are connected to the two external hoses 2201 via an external suction pump. As the external suction pump continuously exhausts air, the two airflows generated during the high-intensity exhaust of air through the two external hoses 2201 and the two exhaust pipes 220 will be uniformly attracted along both sides of the porcelain blank. Under the guidance of the two airflows, the glaze mist sprayed directly along the nozzle 4401 will be uniformly and efficiently sprayed onto the porcelain blank in a fixed position.

[0057] Example 3:

[0058] Combination Figures 8 to 10As shown, in the above embodiment, a slide is provided on the outer wall of the nozzle 440, and an anti-overflow slide plate 4602 is movably installed in the slide. A filter press pad 4603 is fixedly installed in the middle of the inner side of the anti-overflow slide plate 4602, and the filter press pad 4603 is located in the inner cavity of the nozzle 440. A cantilever 4601 is movably installed on the rod end in the middle of the anti-overflow slide plate 4602, and a support plate 460 is movably installed on the other end of the cantilever 4601. A 4402 is fixedly installed on the outer end of the nozzle 440, and a second bidirectional screw 450 is movably installed in the 4402. The support plate 460 is threaded onto the second bidirectional screw 450.

[0059] The arc-shaped guide plate 430 is composed of an arc-shaped plate end and two triangular baffles. The two triangular baffles have gaps between them and the cavities of the first outer shell 310 and the second outer shell 320 after they are closed, which facilitates the enhancement of the fluidity of the glaze.

[0060] Preferably, the protruding plate segments on both sides of the inner ring gasket 410 are respectively inserted into the grooves inside the first outer shell 310 and the second outer shell 320, and anti-overflow rubber rings are fixedly installed on the inner walls of the grooves inside the first outer shell 310 and the second outer shell 320.

[0061] As the motor 3801 runs, the gear 3802 fixedly installed on its internal transmission shaft will drive the ring gear 420. As the inner ring pad 410 is driven and rotates at a uniform speed, the inner ring pad 410 will carry the arc-shaped guide plate 430 to actively stir the glaze in the inner cavity of the first outer shell 310 and the second outer shell 320. While improving the high fluidity of the glaze, the fine glaze after passing through the filter pad 4603 and the nozzle 4401 will be sprayed vertically and evenly onto the outer surface of the porcelain blank.

[0062] In this process, by rotating the second bidirectional lead screw 450, the rotating second bidirectional lead screw 450 will push the pallet 460 to extend laterally. The laterally extended pallet 460 will pull the cantilever 4601 and the anti-overflow slide plate 4602 to slide relative to each other. Finally, the anti-overflow slide plate 4602, together with the filter pad 4603 and the nozzle 4401, will adjust the distance between them to facilitate the adjustment of the flow rate of glaze mist spraying.

[0063] The working principle and process flow of this invention are as follows: The second bidirectional lead screw 450 is pre-rotated. As the second bidirectional lead screw 450 rotates forward, the support plate 460 will move laterally outward along the second bidirectional lead screw 450. The laterally moving support plate 460 will pull the cantilever 4601 and the anti-overflow slide plate 4602 to extend. As the anti-overflow slide plate 4602 drives the filter pad 4603 to approach the nozzle 4401, the glaze transferred from the inner cavity of the first outer shell 310 and the second outer shell 320 to the inside of the spray pipe 440 will pass through the filter pad 4603. After passing through the filter pad 4603, the glaze will be de-aired. The glaze after the air bubbles are de-aired will be sprayed directly outward from the nozzle 4401. The distance between the filter pad 4603 and the nozzle 4401 can be controlled by adjusting the second bidirectional lead screw 450 until the glaze sprayed directly from the nozzle 4401 can be directly controlled.

[0064] Next, the first bidirectional lead screw 140 is rotated. As the first bidirectional lead screw 140 reverses, the end plate 150 moves inward along the first bidirectional lead screw 140. The inward movement of the end plate 150 pushes the two lever arms 1501 to expand outward. The two clamps 1502, which are expanded to their maximum extent, push the two sets of porcelain clamping mechanisms 200 to expand to their maximum state. Then, the porcelain to be glazed is placed in the center of the inner side of the first outer shell 310 and the second outer shell 320. At the same time, the first bidirectional lead screw 140 is controlled to rotate forward. Finally, the end plate 150 drives the two lever arms 1501 and the two clamps 1502 to quickly retract and close. The two sets of porcelain clamping mechanisms 200 quickly clamp and fix the porcelain in the middle of the inner side of the first outer shell 310 and the second outer shell 320.

[0065] Once the porcelain is secured, the motor 3801 is activated via the client. The running motor 3801, in conjunction with gear 3802, drives the ring gear 420 and inner ring pad 410. As the inner ring pad 410 rotates at a constant speed, the arc-shaped guide plate 430 and the nozzle 440, fixed on the inner ring pad 410, rotate regularly around the secured porcelain as their axis. The glaze continuously input through the guide pipe 370 is output through the inner cavities of the first outer shell 310 and the second outer shell 320, and sprayed from the nozzle 4401 onto the outer surface of the porcelain. This process ensures that the glaze can be evenly coated on the outer surface of the porcelain, avoiding the risk of orange peel-like appearance caused by excessively thick glaze layers.

[0066] Meanwhile, as the glaze mist sprayed by the nozzle 4401 diffuses around the porcelain, air is continuously exhausted outward through the two external hoses 2201. The glaze mist diffused around the porcelain is guided towards the arc-shaped plate section at the inner end of the two exhaust pipes 220. Finally, under the suction of the airflow, the diffused glaze mist is forcibly cleared, avoiding the problem of excessive glaze mist diffused around the porcelain, which could cause spots and bubbles on the glaze surface. After the distance between the filter pad 4603 and the nozzle 4401 is reduced by the second bidirectional screw 450, the glaze flowability of the filter pad 4603 and the nozzle 4401 will be further improved after the distance is reduced, avoiding the risk of intermittent spraying due to insufficient glaze flowability.

[0067] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.

A glazing device for ceramic handicrafts according to claim 1, characterized in that, The bottom of the first outer shell (310) and the second outer shell (320) are both fixedly installed with insert plates (340), and the cross section of the insert plates (340) is L-shaped. The two insert plates (340) are snapped with buckles (360) on the outside.

8. A glazing device for ceramic handicrafts according to claim 1, characterized in that, The inner ring pad (410) extends through to the plate end inside the first outer shell (310) and a ring gear (420) is fixedly installed thereon. The gear (3802) is adapted to mesh with the ring gear (420). The arc-shaped guide plate (430) is composed of an arc-shaped plate end and two triangular baffles. The two triangular baffles are reserved with gaps in the cavities of the first outer shell (310) and the second outer shell (320) after closing, so as to enhance the fluidity of the glaze.

9. A glazing device for ceramic handicrafts according to claim 1, characterized in that, The outer wall of the nozzle (440) is provided with a slide rail, and an anti-overflow slide plate (4602) is movably installed in the slide rail. A filter press pad (4603) is fixedly installed in the middle of the inner side of the anti-overflow slide plate (4602), and the filter press pad (4603) is located in the inner cavity of the nozzle (440). A cantilever (4601) is movably installed on the rod end in the middle of the anti-overflow slide plate (4602). A support plate (460) is movably installed at the other end of the cantilever (4601). A (4402) is fixedly installed at the outer end of the nozzle (440). A second bidirectional screw (450) is movably installed in the (4402), and the support plate (460) is threaded onto the second bidirectional screw (450).

10. A glazing process for a glazing device for ceramic handicrafts according to any one of claims 1-9, characterized in that, S1. Rotate the second bidirectional lead screw (450) to drive the pallet (460) to move laterally outward. The outwardly moving pallet (460) will pull the cantilever (4601) and the anti-overflow slide plate (4602) to extend. As the anti-overflow slide plate (4602) drives the filter pad (4603) to approach the nozzle (4401), the glaze transferred from the inner cavity of the first housing (310) and the second housing (320) to the inside of the nozzle (440) will pass through the filter pad (4603) to remove the air bubbles in the glaze. S2. Rotate the first bidirectional lead screw (140) to drive the end plate (150) to move inward laterally. The inwardly moving end plate (150) will push the two lever arms (1501) to open outward. Then, place the porcelain to be glazed in the center of the inner side of the first outer shell (310) and the second outer shell (320). Then control the first bidirectional lead screw (140) to rotate forward, so as to use the two sets of porcelain clamping mechanisms (200) to quickly clamp and fix the porcelain. S3. After the porcelain is fixed, start the motor (3801), drive the ring gear (420) and inner ring pad (410), so that the arc-shaped guide plate (430) and the nozzle (440) fixed on the inner ring pad (410) rotate regularly around the fixed porcelain as the axis, and then spray glaze onto the outer surface of the porcelain through the nozzle (4401) to ensure that the glaze can be evenly coated on the outer surface of the porcelain.
