Description

Technical Field

[0001] The invention relates to the technical field of glaze spraying machines, in particular to a multi-angle ceramic rotary glaze spraying machine. Background Art

[0002] In the production process of ceramic containers, the glazing of the inner surface of the blank is currently mainly done manually, that is, the operator holds the blank with both hands and faces it downward, and compresses the container containing the glaze slurry by foot, so that the glaze slurry is sprayed to form a glaze column and shoots into the interior of the blank, and the blank needs to be shaken at the same time. However, this method has the problems of high labor intensity for operators, low production efficiency and high randomness, making it difficult to ensure uniform glazing of the product, making it difficult to improve the quality of the product. Therefore, there is an urgent need for glaze spraying equipment to improve productivity, reduce the labor intensity of workers and improve the quality of products.

[0003] In order to facilitate the handling and loading of the ceramic container, the existing glaze spraying machine is equipped with a brake mechanism for rotating the rotating ceramic container. However, these brake mechanisms need to be manually tightened and loosened each time they are used, which is troublesome and inconvenient to use.

[0004] Although some brake mechanisms can automatically loosen and tighten before and after painting operations, eliminating the trouble of manual operation, most of them are unable to brake the rotating bearing components for a long period of time, and are unable to brake and maintain the rotating bearing components at the loading and unloading stations of ceramic containers. As a result, when the ceramic containers are loaded and unloaded, the rotating bearing components are still in an unstable state where they can rotate and shift freely, making it inconvenient to load and unload the ceramic containers, and easily causing the ceramic containers to fall and be damaged by impact. Summary of the invention

[0005] In view of this, the present invention provides a multi-angle ceramic rotary glaze spraying machine to solve the problem that most brake mechanisms are unable to brake the rotating bearing components for a long period of time, resulting in that when the ceramic containers are loaded and unloaded, the rotating bearing components are still in an unstable state where they can rotate freely and shift, making it inconvenient to load and unload the ceramic containers.

[0006] The technical solution proposed by the present invention is: a multi-angle ceramic rotary glaze spraying machine, specifically comprising a chassis and a turntable; a turntable is rotatably mounted on the bottom plate of the chassis;

[0007] A circle of vertical rotating shafts is installed around the outer edge of the circumference of the turntable to carry and place the ceramic vessels to be glazed; the part of the vertical rotating shaft protruding from the bottom side of the turntable is equipped with a driving gear; an arc-shaped rack arranged concentrically with the turntable is welded on the chassis; in the use state, following the rotation of the turntable, a circle of driving gears are meshed with the arc-shaped racks in sequence;

[0008] A brake mechanism for stopping the vertical shaft is arranged at the bottom of the turntable near the driving gear, and an arc-shaped driving member arranged concentrically with the turntable is welded to the outer edge of the chassis bottom plate. When the turntable is driven by rotation, when the driving gear contacts the arc-shaped rack, the arc-shaped driving member drives the brake mechanism to release the vertical shaft; when the driving gear disengages from the arc-shaped rack, the arc-shaped driving member drives the brake mechanism to clamp the vertical shaft.

[0009] Furthermore, a central positioning column for vertical support is threadedly fixed at the central position of the chassis bottom plate, and the turntable is rotatably matched with the central positioning column;

[0010] A glaze spray head arranged backward is fixedly installed above the top of the central positioning column, and the glaze spray head corresponds to the arc-shaped rack up and down;

[0011] The arc-shaped rack is located in the middle of the rear side of the internal space of the chassis. The arc-shaped rack and the driving gear are at the same height, and two L-shaped support rods are symmetrically welded between the arc-shaped rack and the bottom plate of the chassis.

[0012] Furthermore, a circle of inclined bearing rods is welded around the top end portion of the vertical rotating shaft, and the ceramic vessel is supported and placed on the circle of inclined bearing rods.

[0013] Furthermore, a driven gear ring is welded at the bottom center of the turntable and rotates with the center positioning column, and a mounting plate is welded at the bottom of the center positioning column. A motor is threadedly fixed on the mounting plate, and the motor meshes with the driven gear ring for transmission.

[0014] Furthermore, the brake mechanism is composed of a brake force-bearing member and a mounting frame, wherein the brake force-bearing member is threadedly mounted on the bottom end of the vertical rotating shaft, and the mounting frame is threadedly mounted on the bottom outer edge of the turntable.

[0015] Furthermore, the brake force-bearing member as a whole is composed of a threaded rod at the top, a force-bearing shaft at the bottom, and a connecting disc welded between the threaded rod and the force-bearing shaft;

[0016] The arc-shaped driving member is an arc-shaped driving plate, which is directly welded to the top of the chassis bottom plate and is vertically opposite to the arc-shaped rack. Both left and right ends of the arc-shaped driving plate are oblique sections.

[0017] Furthermore, two L-shaped slide bars are symmetrically slidably installed on the installation frame by spring pushing, and two arc-shaped pressure plates are symmetrically welded to the head ends of the two L-shaped slide bars. Brake pads are fixed inside the two arc-shaped pressure plates, and the force-bearing axis passes through the center position of the installation frame and is located between the two arc-shaped pressure plates;

[0018] A vertical positioning shaft supporting downward is welded in the middle of the bottom of the installation frame, and a convex support frame is slidably installed on the vertical positioning shaft. The convex support frame is symmetrically rotated with two L-shaped sliding rods, and two connecting rods are connected to the convex support frame. The bottom side of the convex support frame is in contact with the oblique section of the arc-shaped driving plate.

[0019] Furthermore, the brake mechanism is composed of a semicircular pressure plate and a hexagonal sliding shaft;

[0020] The arc-shaped driving member is a retaining ring, a notch is provided on the retaining ring at a position opposite to the arc-shaped rack, and two inclined guide rods arranged opposite to each other are bent at the head and tail ends of the retaining ring near the notch;

[0021] The retaining ring is located above the top end of the chassis bottom plate and is at the same height as the driving gear, and a circle of vertical support plates is welded around the retaining ring and the chassis bottom plate.

[0022] Furthermore, the semicircular pressure plate is slidably installed on the bottom of the turntable by a spring, and a brake pad is fixed inside the semicircular pressure plate and slidably cooperates with the driving gear;

[0023] A hexagonal sliding shaft is welded in the middle position of the semicircular pressure plate, and a circle of threaded T-shaped mounting blocks are hoisted around the bottom outer edge of the turntable. The hexagonal sliding shaft is pushed and slidably fitted with the T-shaped mounting block by a spring, and the head end of the hexagonal sliding shaft rotates with the turntable and slides against the circumferential inner ring of the retaining ring.

[0024] The multi-angle ceramic rotary glaze spraying machine provided by the present invention has the following beneficial effects:

[0025] According to the present invention, when the convex supporting frame is separated from the arc-shaped driving plate and the ceramic vessel is disengaged from the glaze nozzle, the two arc-shaped pressure plates lose the pushing and holding force from the convex supporting frame and can be automatically rebounded and pushed by the springs on the two L-shaped sliding rods to slide towards each other, clamping and braking the force-bearing axis and the vertical rotating shaft, so that the ceramic vessel is relatively still after the glazing is completed, which is convenient for taking and loading and unloading, and avoids the continuous rotation of the vertical rotating shaft after a glazing operation is completed, which makes it impossible for the hands to accurately and stably take the ceramic vessel, which is easy to cause it to fall, hit and break. This helps to reduce the probability of the ceramic vessel falling and breaking when loading and unloading at the top of the vertical rotating shaft.

[0026] In addition, through the power transmission of the arc-shaped driving plate and in conjunction with the springs on the two L-shaped sliding rods, the convex support frame can utilize the driving force transmitted by the rotation of the turntable to drive the up and down sliding movement, and control the two arc-shaped pressure plates to automatically loosen and tighten the vertical rotating shaft before and after the spray glazing operation. Compared with the existing technology, it can save the trouble of manual effort to operate the loosening and tightening of the rotating bearing components before and after each spray glazing operation. The operation is convenient, efficient and labor-saving.

[0027] In addition, when the convex support frame and the arc-shaped driving plate of the present invention are in a disengaged and separated state, the two arc-shaped pressure plates are always pressed and clamped on the force-bearing shaft to maintain the braking position of the vertical rotating shaft. Compared with the prior art, the rotating bearing component can be braked for a longer period of time, and the rotating bearing component can be braked and maintained when the ceramic vessel is conveyed to the loading and unloading station in the front opening of the chassis, so that the ceramic vessel can be stably kept in a stationary state during loading and unloading, which is convenient for picking up, and helps to further reduce the probability of ceramic vessels falling and breaking when loading and unloading at the top of the vertical rotating shaft, thereby ensuring the safety of ceramic vessels during loading and unloading.

[0028] In addition, compared with the braking system of embodiment 1, which is composed of two arc-shaped pressure plates, two connecting rods, a convex support frame, a mounting frame and an arc-shaped drive plate, the braking system of embodiment 2 of the present invention is composed of a hexagonal sliding shaft, a semicircular pressure plate and a retaining ring. It has fewer parts and a simpler structure, and has a lower cost and difficulty in production and manufacturing, which is more convenient for market promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0053] For convenience of description, the opening side of the chassis 1 is marked as the front direction, and the opposite side of the opening is marked as the rear direction;

[0054] Please refer to Figures 1 to 8 ;

[0055] For convenience of description, the opening side of the chassis 1 is marked as the front direction, and the opposite side of the opening is marked as the rear direction;

[0056] Embodiment 1:

[0057] The present invention provides a multi-angle ceramic rotary glaze spraying machine, comprising a chassis 1 and a turntable 2; the turntable 2 is rotatably mounted on the bottom plate of the chassis 1, and the front end of the chassis 1 is opened;

[0058] Among them, a circle of vertical rotating shafts 201 are installed around the outer edge of the circumference of the turntable 2 to carry and place the ceramic vessels to be glazed; the part of the vertical rotating shaft 201 protruding from the bottom side of the turntable 2 is equipped with a driving gear 203; an arc-shaped rack 206 arranged concentrically with the turntable 2 is welded on the chassis 1; in the use state, following the rotation of the turntable 2, a circle of driving gears 203 are meshed with the arc-shaped rack 206 in turn, and the ceramic vessels are taken in and unloaded at the front port of the chassis 1;

[0059] A brake mechanism for stopping the vertical shaft 201 is arranged at the bottom of the turntable 2 near the driving gear 203, and an arc-shaped driving member arranged concentrically with the turntable 2 is welded on the outer edge of the bottom plate of the chassis 1. When the drive gear 203 contacts the arc-shaped rack 206 under the rotation drive of the turntable 2, the arc-shaped driving member drives the brake mechanism to release the vertical shaft 201, and when the drive gear 203 disengages from the arc-shaped rack 206, the arc-shaped driving member drives the brake mechanism to clamp the vertical shaft 201.

[0060] Preferably, a central positioning column 101 for vertical support is threadedly fixed at the central position of the bottom plate of the chassis 1, and the turntable 2 is rotatably matched with the central positioning column 101;

[0061] A glaze spray head 4 arranged backward is fixedly installed above the top of the central positioning column 101. The glaze spray head 4 corresponds to the arc-shaped rack 206 up and down. The turntable 2 rotates around the central positioning column 101 to transport the ceramic vessels, and is used to drive the ceramic vessels to pass through the glaze spray head 4 in sequence for spraying glaze;

[0062] The arc-shaped rack 206 is located in the middle of the rear side of the internal space of the chassis 1. The arc-shaped rack 206 and the driving gear 203 are at the same level, and two L-shaped support rods are symmetrically welded between the arc-shaped rack 206 and the bottom plate of the chassis 1.

[0063] A vertical support shaft is welded to the top of the center positioning column 101, a T-shaped mounting seat 102 is welded to the top of the vertical support shaft, a horizontal mounting rod for rearward support is welded to the T-shaped mounting seat 102, and the glaze nozzle 4 is threadedly connected to the head end of the horizontal mounting rod.

[0064] Preferably, a circle of inclined supporting rods 202 is welded around the top portion of the vertical rotating shaft 201, and the ceramic vessel is supported and placed on the circle of inclined supporting rods 202. Through the power transmission of the arc-shaped rack 206, the turntable 2 can engage and drive a circle of driving gears 203 and the vertical rotating shaft 201 and the ceramic vessel to rotate in sequence when being driven to rotate, and multi-angle comprehensive spray glazing is implemented at the bottom of the glaze nozzle 4. The position of the glaze nozzle 4 corresponds to the arc-shaped rack 206 up and down, so that the vertical rotating shaft 201 and the driving gear 203 can be engaged and driven to rotate only when they are transmitted to the bottom of the glaze nozzle 4.

[0065] Preferably, a driven gear ring 205 that rotates with the center positioning column 101 is welded at the bottom center position of the turntable 2, and a mounting plate is welded at the bottom of the center positioning column 101, and a motor 5 is threadedly fixed on the mounting plate. The motor 5 is engaged with the driven gear ring 205 for transmission. Through the driven gear ring 205, the motor 5 can rotate and engage to drive the turntable 2 to rotate and transmit.

[0066] Preferably, the brake mechanism is composed of a brake force-bearing member 204 and a mounting frame 3 , wherein the brake force-bearing member 204 is threadedly mounted on the bottom end of the vertical shaft 201 , and the mounting frame 3 is threadedly mounted on the bottom outer edge of the turntable 2 .

[0067] Preferably, the brake force-bearing member 204 is composed of a threaded rod 2041 at the top, a force-bearing shaft 2042 at the bottom, and a connecting disc welded between the threaded rod 2041 and the force-bearing shaft 2042;

[0068] The arc driving member is an arc driving plate 7, which is directly welded to the top of the bottom plate of the chassis 1 and is vertically opposite to the arc rack 206, and both left and right ends of the arc driving plate 7 are oblique sections.

[0069] Preferably, two L-shaped slide bars 301 are symmetrically slidably installed on the installation frame 3 through spring pushing, and two arc-shaped pressure plates 3011 are symmetrically welded at the head ends of the two L-shaped slide bars 301. Brake pads are fixed inside the two arc-shaped pressure plates 3011. The force-bearing shaft 2042 is passed through the center position of the installation frame 3 and is located between the two arc-shaped pressure plates 3011. When the two arc-shaped pressure plates 3011 slide close to each other and contact the force-bearing shaft 2042, they are used to apply top pressure to the vertical rotating shaft 201 and clamp the brake;

[0070] A vertical positioning shaft 304 supporting downward is welded to the middle position of the bottom of the installation frame 3, and a convex support frame 303 is slidably installed on the vertical positioning shaft 304. The convex support frame 303 and the two L-shaped slide bars 301 are symmetrically rotated and connected with two connecting rods 302. Following the rotation of the turntable 2, the bottom side of the convex support frame 303 abuts against the oblique section of the arc-shaped driving plate 7. The two arc-shaped pressure plates 3011, the two connecting rods 302 and the convex support frame 303 are connected together to form two crank slider mechanisms. Through these two crank slider mechanisms, the convex support frame 303 that slides up and down can push and drive the two arc-shaped pressure plates 3011 to slide toward each other and contact and clamp with the force-bearing shaft 2042 and move away from it to loosen it, thereby loosening and braking the vertical rotating shaft 201.

[0071] The convex support frame 303 is hoisted at the bottom of the turntable 2 and can rotate with the turntable 2. Through the arc-shaped driving plate 7 and the inclined guiding principle of its oblique section structure, when the turntable 2 is rotating and conveying, when the ceramic vessel is conveyed close to the glaze spray head 4, the convex support frame 303 can be pushed upward to control the two arc-shaped pressing plates 3011 to slide away from each other to release the force-bearing shaft 2042, so that the vertical rotating shaft 201 can be restored to freedom and can be meshed with the arc-shaped rack 206 to drive the ceramic vessel to rotate for spraying glazing;

[0072] When the convex support frame 303 is separated from the arc driving plate 7 and the ceramic vessel is disengaged from the glaze nozzle 4, the two arc pressure plates 3011 lose the pushing and holding force from the convex support frame 303, and can be automatically rebounded and pushed by the springs on the two L-shaped slide bars 301 to slide towards each other, clamping and braking the force-bearing shaft 2042 and the vertical rotating shaft 201, so that the ceramic vessel is relatively still after the glaze spraying is completed, which is convenient for taking and loading and unloading, and avoids the vertical rotating shaft 201 from continuously rotating after a glaze spraying operation is completed, causing the hand to be unable to accurately and stably take the ceramic vessel, which is easy to fall, hit and break, which helps to reduce the probability of the ceramic vessel falling and breaking when loading and unloading at the top of the vertical rotating shaft 201;

[0073] Then, through the power transmission of the arc-shaped driving plate 7 and in conjunction with the springs on the two L-shaped slide bars 301, the convex support frame 303 can be driven to slide up and down by the driving force transmitted by the rotation of the turntable 2, and the two arc-shaped pressing plates 3011 are controlled to automatically loosen or tighten the vertical rotating shaft 201 before and after the spray glazing operation. Compared with the prior art, the trouble of manually loosening or tightening the rotating bearing component before and after each spray glazing operation can be eliminated, and the operation is convenient, efficient, and labor-saving.

[0074] When the convex support frame 303 of the present invention is in a disengaged and separated state from the arc-shaped driving plate 7, the two arc-shaped pressure plates 3011 are always pressed and clamped on the force-bearing shaft 2042 to maintain the braking position of the vertical rotating shaft 201. Compared with the prior art, the rotating bearing component can be braked for a longer period of time, and the rotating bearing component can be braked and maintained when the ceramic vessel is conveyed to the loading and unloading station in the front end opening of the chassis 1, so that the ceramic vessel can be stably kept in a stationary state during loading and unloading, which is convenient for picking up, and helps to further reduce the probability of ceramic vessels falling and breaking when loading and unloading at the top of the vertical rotating shaft 201, thereby ensuring the safety of ceramic vessels during loading and unloading.

[0075] A push short shaft 3031 is welded to the middle position of the bottom of the convex support frame 303, and a guide ball is embedded in the bottom end of the push short shaft 3031. The convex support frame 303 indirectly contacts the inclined section of the arc driving plate 7 through the push short shaft 3031 and the guide ball at its bottom end.

[0076] On the basis of the first embodiment, the second embodiment, as Figures 10 to 12 As shown:

[0077] A multi-angle ceramic rotary glaze spraying machine, further comprising a brake mechanism composed of a semicircular pressing plate 6 and a hexagonal sliding shaft 601;

[0078] The arc-shaped driving member is a retaining ring 207, and a notch is provided on the retaining ring 207 at a position opposite to the arc-shaped rack 206. Two inclined guide rods 2071 arranged opposite to each other are bent at the head and tail ends of the retaining ring 207 near the notch.

[0079] The retaining ring 207 is located above the top of the bottom plate of the chassis 1 and is at the same height as the driving gear 203 , and a circle of vertical support plates is welded around the retaining ring 207 and the bottom plate of the chassis 1 .

[0080] Preferably, the semicircular pressure plate 6 is installed at the bottom of the turntable 2 by a spring push and sliding, and a brake pad is fixed inside the semicircular pressure plate 6 and slides with the driving gear 203. When the semicircular pressure plate 6 slides inward and presses against the driving gear 203, it is used to brake the vertical shaft 201;

[0081] A hexagonal sliding shaft 601 is welded to the middle position of the semicircular pressing plate 6, and a circle of threaded T-shaped mounting blocks 208 are hoisted around the bottom outer edge of the turntable 2. The hexagonal sliding shaft 601 is pushed and slidably matched with the T-shaped mounting block 208 through a spring, and the head end part of the hexagonal sliding shaft 601 follows the rotation of the turntable 2 and slides against the inner circle of the circumference of the retaining ring 207. When the hexagonal sliding shaft 601 is in contact with the retaining ring 207, it is pushed inward by the retaining ring 207, and the semicircular pressing plate 6 is pressed and clamped on the driving gear 203, which continuously brakes the vertical rotating shaft 201 for a long time, so that the vertical rotating shaft 201 remains stationary and stopped during the entire rotation and transmission stroke except for the glazing station at the bottom of the glaze nozzle 4, so as to realize the stable picking up and loading and unloading of ceramic vessels at the loading and unloading stations;

[0082] When the hexagonal sliding shaft 601 and the semicircular pressing plate 6 follow the turntable 2 to transfer to the gap of the retaining ring 207 and are located at the bottom of the glaze nozzle 4 for spray glazing, the hexagonal sliding shaft 601 is separated from the retaining ring 207, and the semicircular pressing plate 6 loses the inner sliding top pressure holding force from the semicircular pressing plate 6, and can be automatically rebounded by the spring on the hexagonal sliding shaft 601 to push the outer sliding reset to release the driving gear 203, so that the vertical rotating shaft 201 can be restored to freedom and can be meshed with the arc-shaped rack 206 to drive the ceramic vessel to rotate for spray glazing, and through the inclined guide principle of the inclined guide rod 2071, when the hexagonal sliding shaft 601 and the semicircular pressing plate 6 are transferred through the gap to complete the spray glazing of the ceramic vessel, the turntable 2 can also drive the hexagonal sliding shaft 601 to slide inward to restore the sliding contact with the inner ring of the retaining ring 207, and automatically push the semicircular pressing plate 6 to restore the continuous braking of the vertical rotating shaft 201;

[0083] In this embodiment, the brake system composed of the hexagonal sliding shaft 601, the semicircular pressure plate 6 and the retaining ring 207 is less than that of the first embodiment, which is composed of two arc pressure plates 3011, two connecting rods 302, a convex support frame 303, a mounting frame 3 and an arc driving plate 7. The structure is simpler, the cost and the difficulty of production are lower, and it is more convenient for market promotion.

[0084] A guide wheel is rotatably mounted on the head end of the hexagonal sliding shaft 601 , and the hexagonal sliding shaft 601 is indirectly in sliding contact with the inner ring of the retaining ring 207 through the guide wheel.

[0085] Working principle of implementation one: ceramic vessels are taken in and unloaded at the front port of the chassis 1, and the motor 5 can rotate and mesh to drive the turntable 2 to rotate and transmit through the driven gear ring 205, and the turntable 2 rotates around the central positioning column 101 to transmit the ceramic vessels, which is used to drive the ceramic vessels to pass through the glaze nozzle 4 in sequence for spray glazing, and the motor 5 can rotate and mesh to drive the turntable 2 to rotate and transmit through the driven gear ring 205, and through the power transmission of the arc-shaped rack 206, the turntable 2 can mesh to drive a circle of driving gear 203 and the vertical shaft 201 and the ceramic vessels to rotate in sequence when being driven to rotate and transmit, and implement multi-angle and comprehensive spray glazing at the bottom of the glaze nozzle 4, and the position of the glaze nozzle 4 and the arc-shaped rack 206 corresponds up and down, so that the vertical shaft 201 and the driving gear 203 can be meshed and driven to rotate only when they are transmitted to the bottom of the glaze nozzle 4;

[0086] When the two arc-shaped pressure plates 3011 slide towards each other and contact the force-bearing shaft 2042, they are used to apply pressure, clamping and braking to the vertical rotating shaft 201. The two arc-shaped pressure plates 3011, the two connecting rods 302 and the convex support frame 303 are connected together to form two crank slider mechanisms. Through the two crank slider mechanisms, the convex support frame 303 that slides up and down can push and drive the two arc-shaped pressure plates 3011 to slide towards each other and contact and clamp with the force-bearing shaft 2042 and move away from each other to loosen, thereby applying pressure and braking to the vertical rotating shaft 201.

[0087] The convex support frame 303 is hoisted at the bottom of the turntable 2 and can rotate with the turntable 2. Through the arc-shaped driving plate 7 and the inclined guiding principle of its oblique section structure, when the turntable 2 is rotating and conveying, when the ceramic vessel is conveyed close to the glaze spray head 4, the convex support frame 303 can be pushed upward to control the two arc-shaped pressing plates 3011 to slide away from each other to release the force-bearing shaft 2042, so that the vertical rotating shaft 201 can be restored to freedom and can be meshed with the arc-shaped rack 206 to drive the ceramic vessel to rotate for spraying glazing;

[0088] When the convex support frame 303 is separated from the arc-shaped driving plate 7 and the ceramic vessel is disengaged from the glaze spray head 4, the two arc-shaped pressing plates 3011 lose the pushing and holding force from the convex support frame 303, and can be automatically rebounded and pushed by the springs on the two L-shaped slide bars 301 to slide closer to each other, clamping and braking the force-bearing shaft 2042 and the vertical rotating shaft 201, so that the ceramic vessel is relatively still after the glaze spraying is completed, which is convenient for taking and loading;

[0089] The working principle of the second implementation: when the semicircular pressure plate 6 slides inwards and presses against the driving gear 203, it is used to press and brake the vertical shaft 201. The hexagonal sliding shaft 601 is pushed and slidably matched with the T-shaped mounting block 208 through the spring. The head end of the hexagonal sliding shaft 601 rotates with the turntable 2 and slides against the inner circle of the retaining ring 207. When the hexagonal sliding shaft 601 is in contact with the retaining ring 207, it is pushed inwards by the retaining ring 207 and presses the semicircular pressure plate 6 against the driving gear 203, which continuously brakes the vertical shaft 201 for a long time, so that the vertical shaft 201 remains stationary and stopped during the entire rotation and transmission stroke except for the glazing station at the bottom of the glaze nozzle 4, so as to realize the stable loading and unloading of ceramic vessels at the loading and unloading stations.

[0090] When the hexagonal sliding shaft 601 and the semicircular pressure plate 6 follow the turntable 2 to transfer to the gap of the retaining ring 207 and are located at the bottom of the glaze nozzle 4 for spray glazing, the hexagonal sliding shaft 601 disengages from the retaining ring 207, and the semicircular pressure plate 6 loses the inner sliding top pressure holding force from the semicircular pressure plate 6. It can be automatically rebounded and pushed outward by the spring on the hexagonal sliding shaft 601 to slide back and forth to release the driving gear 203, so that the vertical rotating shaft 201 can regain freedom and be able to engage with the arc-shaped rack 206 to drive the ceramic vessel to rotate for spray glazing. And through the inclined guide principle of the inclined guide rod 2071, when the hexagonal sliding shaft 601 and the semicircular pressure plate 6 transfer through the gap and complete the spray glazing of the ceramic vessel, the turntable 2 can also drive the hexagonal sliding shaft 601 to slide inward to restore the sliding abutment contact with the inner ring of the retaining ring 207, and automatically push the semicircular pressure plate 6 to restore the continuous braking of the vertical rotating shaft 201.
