Description

Technical Field

[0001] The present invention relates to the technical field of automatic production equipment for ceramic utensils, in particular to an automatic glaze spraying device inside a pot. Background Art

[0002] A clay pot is a traditional cooking utensil, usually made of clay or ceramic. It has good heat retention and heat resistance, making it suitable for cooking methods such as slow cooking, making soups, and making porridge. In traditional ceramic manufacturing processes, the glaze coating on the inside of the clay pot is usually done manually, that is, by hand-dipping, brushing, or simple spraying. However, manual glazing has many limitations: on the one hand, the quality of manual glazing is unstable, which can easily cause uneven glaze thickness, leading to defects such as glaze cracking, glaze shrinkage, or color differences in the product after firing; on the other hand, manual operation is inefficient, and long-term contact with glaze may pose a health hazard to workers.

[0003] In recent years, automated glazing technology has been gradually adopted by the ceramics industry. However, existing equipment is mostly designed for flat tiles or simple shapes (such as bowls and plates). Its spray gun trajectory is fixed or only offers two-dimensional adjustment, making it unable to adapt to the three-dimensional curved surfaces of clay pots. Furthermore, the complex structure of clay pots (such as large aspect ratios and varying curvatures) makes it difficult for conventional mechanical glazing equipment to achieve precise glaze coverage. In particular, the edges of the spray area often suffer from blurred boundaries, impacting product competitiveness. Summary of the Invention

[0022] Reference Figures 1 to 7 The automatic glaze spraying device in the pot of the present invention is made into the following embodiments: An automatic glaze spraying device in a pot includes: a conveying device 100 and a glaze spraying device 200.

[0023] The conveying device 100 has a conveying surface for supporting and conveying foreign materials, and the conveying surface is provided with a glaze spraying station. The glaze spraying device 200 includes a glaze spraying mechanism 210 and a lifting drive mechanism 220. The glaze spraying mechanism 210 is provided above the glaze spraying station, and the lifting drive mechanism 220 is used to drive the glaze spraying mechanism 210 to move up and down.

[0024] The glaze spraying mechanism 210 includes: a glaze spraying component 211, a rotation driving component 212 and a sealing cover 213. The sealing cover 213 is arranged at the lower end of the glaze spraying mechanism 210. The sealing cover 213 has a glaze spraying hole 2131 that passes through from top to bottom. The glaze spraying component 211 has a nozzle 2111 that is connected to a glaze source. The nozzle 2111 is arranged in the glaze spraying hole 2131 and is tilted downward. The rotation driving component 212 has a rotation driving end that is transmission-connected to the glaze spraying component 211 and causes the nozzle 2111 to rotate relative to the sealing cover 213.

[0025] In actual use, the clay pot to be glazed is transported along the conveying surface by the conveying device 100. When the pot is transported to the glazing station, the lifting drive mechanism 220 drives the glazing mechanism 210 to move downward, covers the pot mouth of the pot through the sealing cover 213, and the nozzle 2111 extends into the pot from the glazing hole 2131, thereby spraying glaze on the inner wall of the pot. The rotating drive component 212 drives the downward-tilted nozzle 2111 so that the spraying position can completely cover the glazing range in the pot. Since the sealing cover 213 can provide a shield for the edge of the pot where glaze does not need to be sprayed, a clear boundary can be formed at the edge of the glazing range to ensure the glazing effect. The automatic glazing equipment in the pot of the present application realizes the transportation and glazing of the pot through automation, improves production efficiency, reduces labor costs and waste of raw materials, and has important industrial application value.

[0026] Furthermore, to prevent the clay pot's delivery position deviation from affecting the glazing effect of the glazing mechanism 210, the automatic glazing device in the pot also includes a positioning device 300. The positioning device 300 is provided at the glazing station and includes a positioning member 310 and a positioning drive member 320. The positioning drive member 320 is used to drive the positioning member 310 to move, thereby positioning the material in the glazing station.

[0027] In addition to the two symmetrical ears, the body of the clay pot is in the shape of a rotating body. In this embodiment, the glaze spraying station has a central axis extending up and down, the sealing cover 213 and its glaze spraying hole 2131 are both coaxially arranged with the central axis, and the nozzle 2111 rotates around the central axis. In order to improve the quality of glazing, during the glazing process, the clay pot blank needs to be coaxially arranged with the central axis. The plurality of positioning members 310 are evenly distributed around the circumference of the central axis, and the positioning drive member 320 is used to drive the plurality of positioning members 310 to synchronously approach or move away from the central axis. The plurality of positioning members 310 can provide positioning edges for different positions of the clay pot blank, so that the clay pot blank can be coaxially arranged in the glaze spraying station, ensuring that the glaze can be evenly coated in the clay pot when the nozzle 2111 rotates.

[0028] It is worth noting that the central axis is a virtual feature, which is provided to facilitate accurate description of the position and structure of the glaze spraying mechanism 210 and the positioning device 300.

[0029] The positioning member 310 is slidably mounted in a direction perpendicular to the central axis. The positioning drive member 320 includes a drive disk 321 and a positioning drive unit 322. The positioning drive unit 322 is configured to drive the drive disk 321 to rotate coaxially about the central axis. The drive disk 321 is provided with a drive slot 3211. The positioning member 310 includes a drive portion 311 slidably embedded in the drive slot 3211.

[0030] When the positioning drive unit 322 drives the drive disk 321 to rotate, the drive portion 311 can be driven to move through the drive slot 3211, thereby achieving sliding control of the positioning member 310. Referring to the drawings, the positioning member 310 of this embodiment is cylindrical and extends vertically, and four positioning members 310 are evenly distributed around the central axis.

[0031] The positioning device 300 includes a positioning base plate 330 fixedly mounted below the conveying surface. A disc-shaped drive plate 321 is rotatably mounted above the positioning base plate 330. Four drive slots 3211 are evenly distributed circumferentially on the drive plate 321. The drive slots 3211 extend along an arc path, with one end of the drive slot 3211 positioned closer to the central axis and the other end further away from the central axis. The drive portion 311 is always positioned at the intersection of the sliding path of the positioning member 310 and the drive slot 3211. When the drive plate 321 rotates, the drive slot 3211 rotates relative to the positioning base plate 330, thereby driving the positioning member 310 along its sliding path toward or away from the central axis, thereby positioning the pot within the glazing station.

[0032] Furthermore, the driving portion 311 is rotatably provided with a bearing, and the bearing is rollingly embedded in the driving groove 3211. The bearing reduces the friction resistance between the driving portion 311 and the driving groove 3211, making the driving of the positioning member 310 more sensitive.

[0033] In this embodiment, the conveyor device 100 utilizes a belt conveyor mechanism, comprising a conveyor belt 110 that moves along a loop path. The conveyor belt 110 is wound around a pulley, which is driven by a servo motor to rotate, thereby moving the conveyor belt 110. The belt surface of the conveyor belt 110 supports and conveys materials. The conveyor device 100 includes a support plate 120, on which the upper surface of the conveyor belt 110 extends in the front-to-back direction and is laid. The support plate 120 provides support for the conveyor belt 110, preventing it from falling and allowing the upper surface of the conveyor belt 110 to extend in the front-to-back direction.

[0034] The positioning device 300 is arranged on the lower side of the support plate 120, and the support plate 120 is provided with a avoidance groove 121 running through the upper and lower parts. The positioning member 310 is movably arranged in the avoidance groove 121, and the upper end of the positioning member 310 extends to the upper side of the support plate 120 and is higher than the conveying surface to position the material on the conveying surface.

[0035] The avoidance groove 121 is arranged along the sliding path of the positioning member 310. In the present embodiment, the sliding paths of the four positioning members 310 all extend in the horizontal direction, and the sliding paths are all inclined at an angle of 45° to the front-back direction and the left-right direction. The four positioning members 310 are arranged in pairs on the left and right sides of the conveyor belt 110. The width of the conveyor belt 110 should not be too large to avoid obstruction to the movement of the positioning members 310. In the present embodiment, the width of the conveyor belt 110 is consistent with the diameter of the bottom of the clay pot. In the projection in the up and down directions, the outer body of the clay pot is exposed on the left and right sides of the conveyor belt 110. The positioning member 310 can act on the four positions of the clay pot to achieve centering positioning.

[0036] In this embodiment, the clay pot can be centered by the four positioning members 310. The upper ends of the positioning members 310 are each provided with a cylindrical positioning portion having an outer layer made of soft material to avoid scratches on the clay pot.

[0037] In some other embodiments, there are two positioning members 310, each of which is disposed on the left and right sides of the conveyor belt 110. The two positioning members 310 are provided with arc-shaped positioning portions facing each other, and the positioning drive member 320 is used to drive the two positioning members 310 toward each other or away from each other in the left and right directions. The two positioning portions press against the clay pot to achieve positioning of the clay pot.

[0038] In this embodiment, the sealing cover 213 is annular, with the glaze spraying hole 2131 coaxially located in the center of the sealing cover 213. The outer diameter of the sealing cover 213 is tailored to the inner diameter of the pot's rim. When the glaze spraying mechanism 210 moves downward, the sealing cover 213 is positioned firmly against the inside of the pot. To prevent injuries, the sealing cover 213 is elastically attached to the lower end of the glaze spraying member 211 in the vertical direction.

[0039] Referring to the drawings, the glaze spraying mechanism 210 further includes a glaze spraying bracket 214 , a rotating shaft 215 and a glaze tank 216 .

[0040] The sealing cover 213 is provided at the lower end of the glaze spraying bracket 214. The glaze spraying bracket 214 has a through hole extending therethrough, which is coaxially aligned with the glaze spraying hole 2131. The elastic connection between the sealing cover 213 and the glaze spraying bracket 214 can refer to existing elastic connection methods, which are described in detail with examples in this application.

[0041] The rotating shaft 215 is provided at the rear side of the glaze spraying bracket 214, and the glaze jar 216 is fixedly provided at the front side of the glaze spraying bracket 214. The rotating shaft 215 extends in the up-down direction and is rotatably connected to the glaze spraying bracket 214. The rotating shaft 215 is coaxially arranged with the central axis, and the rotating drive member 212 is drivingly connected to the rotating shaft 215. In order to facilitate the control of the speed and accuracy of the rotational action, in this embodiment, the rotating drive member 212 adopts a servo motor, and a belt drive is adopted between the output shaft of the rotating drive member 212 and the rotating shaft 215 to achieve synchronous transmission connection. In other embodiments, the rotating drive member 212 can adopt a rotating drive element such as a rotary cylinder, a stepping motor or a pneumatic motor, and other transmission methods such as chain drive, gear drive or worm gear drive can be adopted between the rotating drive member 212 and the rotating shaft 215.

[0042] The nozzle 2111 is disposed at the lower end of the rotating shaft 215. A valve-controlled element is connected to the nozzle 2111, which controls the start and stop of the nozzle 2111. A water-gas slip ring 217 is coaxially disposed at the upper end of the rotating shaft 215. The water-gas slip ring 217 has multiple sets of corresponding inlets and outlets. One set of inlets and outlets is connected to the glaze tank 216 and the nozzle 2111, respectively, while another set of inlets and outlets is connected to a high-pressure gas source and the valve-controlled element, respectively.

[0043] The water-gas slip ring 217 is used to transfer liquid or gas between the rotating component and the fixed pipe while maintaining a seal to prevent leakage. The water-gas slip ring 217 provides gas and liquid transportation while preventing pipe entanglement, allowing the nozzle 2111 to continue rotating without resetting.

[0044] Furthermore, the rotating shaft 215 is a hollow structure, having an inner cavity extending vertically. Through holes are provided on the upper and lower sidewalls of the rotating shaft 215, connecting the outer environment and the inner cavity. In actual use, the connecting pipeline between the outlet of the water-gas slip ring 217 and the nozzle 2111 or valve control element can be arranged along the inner cavity of the rotating shaft 215.

[0045] In order to prevent dust or foreign matter in the clay pot from affecting the glaze spraying, the automatic glaze spraying equipment in the pot is also provided with a purge device 400. The conveying surface is also provided with a purge station, which is located upstream of the glaze spraying station along the conveying direction of the conveying device 100.

[0046] The purging device 400 includes a blowing pipe 410 and a material blocking mechanism 420. The blowing pipe 410 is arranged above the purging station, is connected to a high-pressure air source and is provided with an air outlet arranged downward.

[0047] The material blocking mechanism 420 includes a block 421 and a block drive member 422. The blocks 421 are arranged in pairs, one on each side of the purge station. The block drive member 422 is used to drive the two blocks 421 to extend from the outside to the upper side of the conveying surface, thereby blocking the material from the purge station.

[0048] During the production process, the material is confined to the purging station by the material blocking mechanism 420, and then the dust or foreign matter inside the clay pot is blown away by the blowing pipe 410. The purged material is then transported to the glazing station for glazing treatment.

[0049] In this embodiment, the material-blocking driving component 422 includes two rotary downward-pressing cylinders, and the two rotary downward-pressing cylinders are respectively connected to the two blocks 421 arranged in pairs. The rotary downward-pressing cylinder is a pneumatic component that combines rotational motion and linear downward-pressing action, and is often used in scenarios that require rotation and pressure application. In actual use, the rotary downward-pressing cylinder can drive the block 421 to rotate from the outside to the upper side of the conveying surface, thereby providing blocking positioning for the clay pots on the conveying surface for purging. After the block 421 is unscrewed outward, it can avoid the space required for the forward and backward transportation of the clay pots through the lifting function, especially to avoid obstruction or scratches on the pot ears.

[0050] In order to improve the glaze spraying efficiency, the conveying device 100 is arranged with multiple glaze spraying stations, and multiple glaze spraying mechanisms 210 are arranged in a one-to-one correspondence with the glaze spraying stations. The lifting drive mechanism 220 synchronously drives the multiple glaze spraying mechanisms 210 to move up and down.

[0051] Referring to the accompanying drawings, the conveying device 100 has four conveying belts 110 arranged left and right, the four positioning devices 300 are arranged one by one on the lower side of the conveying surface, and the four glaze spraying mechanisms 210 are arranged one by one above the glaze spraying station.

[0052] The lifting drive mechanism 220 includes: a lifting frame and a lifting drive component. The four glaze spraying mechanisms 210 are arranged in the left and right directions and installed on the lifting frame. The lifting drive component has a lifting drive end that is transmission-connected to the lifting frame and enables the lifting frame to move up and down relative to the conveying device 100.

[0053] In this embodiment, the lifting drive assembly includes a lifting drive motor 221, a drive shaft, a lifting gear, and a lifting rack 222. Two lifting racks 222 are disposed on the left and right sides. The lifting racks 222 are fixedly connected to the lifting frame and are connected to the conveyor 100 for upward and downward sliding movement via the frame. The drive shaft extends in the left-right direction, and lifting gears are coaxially disposed at both ends of the drive shaft. The lifting gears and the lifting racks 222 are in one-to-one transmission engagement with each other. The output shaft of the lifting drive motor 221 is in transmission connection with the drive shaft.

[0054] In actual use, the lifting drive motor 221 drives the two lifting gears to rotate synchronously through the driving shaft, thereby driving the lifting frame to move up and down through the lifting rack 222. The lifting rack 222 serves as a connecting part for the lifting frame to slide in the up and down directions, and also serves as a transmission part for the lifting drive.

[0055] In other embodiments, the lifting drive mechanism 220 may adopt a linear drive component such as a cylinder, an electric push rod, a hydraulic push rod, or a screw nut drive assembly.

[0056] In some other embodiments, a plurality of the glaze spraying stations may be arranged on the conveying surface along the front-to-back direction, and a plurality of the glaze spraying mechanisms 210 may be arranged along the front-to-back direction.
