Description

Technical Field

[0001] This invention relates to the field of ceramic glazing technology, specifically to an automatic glazing device for ceramic blanks. Background Technology

[0002] Ceramic glazing is a process that uses high-temperature treatment to form a glassy layer of glaze on the surface of a ceramic body. Its main functions include improving the physicochemical properties of the body surface, enhancing the product's aesthetics and performance. Traditional glazing methods encompass seven major categories, including dipping, pouring, and spraying. Modern processes, combined with intelligent equipment, have achieved glaze recovery and automated spraying. The ceramic glazing process involves key steps such as body pretreatment, glaze preparation, glazing operation, and firing temperature control.

[0003] Automatic ceramic glazing devices feed ceramic blanks into a storage cylinder, allowing the glaze to adhere to the surface of the blanks, thus achieving glazing. However, existing automatic ceramic glazing devices, due to the clamping of the blanks during feeding and their independent removal after glazing, can only support a limited number of blanks for glazing at a time, significantly restricting their effectiveness and hindering the full realization of their advantages. Furthermore, an automatic glazing device for anti-flow glaze on antibacterial and easy-to-clean sanitary ware ceramics (publication number CN222450794U), which uses a lifting mechanism, leveling mechanism, and positioning rotation mechanism to transport the anti-flow glaze blanks into the storage cylinder for rotational glazing, also reflects the aforementioned technical problems. Therefore, providing an automatic ceramic glazing device is a problem urgently needing to be solved by those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing automatic ceramic glazing devices, which rely on clamps to fix ceramic blanks during feeding and remove them independently after glazing, limiting the number of ceramic blanks that can be glazed at a time and hindering the advantages of automatic ceramic glazing devices, this application provides an automatic ceramic blank glazing device. By placing multiple ceramic blanks with their openings facing down inside multiple blank positioning slots, and using a loading and unloading control component to control the movement of a support tray on one side of the lifting platform towards or away from the glazing support, as well as to control the up and down movement of the support tray, multiple ceramic blank fixing components can be simultaneously controlled by a synchronous drive component to flip multiple blank fixing components from the top of the glazing support through the blank movement slots to the bottom. This allows multiple ceramic blanks outside the blank support to be simultaneously flipped into the glaze pool, facilitating efficient glazing of a large number of ceramic blanks.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is: An automatic glazing device for ceramic blanks includes a glazing support, a loading and unloading control component, and a synchronous drive component. Multiple blank fixing components are provided on the top of the glazing support. The loading and unloading control components are located on one side of the glazing bracket; The synchronous drive component is located on the side of the glazing bracket away from the loading and unloading control component; Each of the aforementioned blank fixing components includes multiple U-shaped steel parts, and a blank support is provided between the tops of two adjacent U-shaped steel parts. The multiple U-shaped steel parts are arranged in a straight line, and L-shaped steel parts are provided at both ends. The interior of the glazing bracket is provided with multiple blank movable slots, and the external of the multiple blank fixing components is movably connected to the same bearing tray. Each of the aforementioned blank support pieces includes a suspension seat, the top of which is provided with a support head. Two pressure arms symmetrical about their center are threadedly connected to the bottom edge of the support head. Opening and closing arms are hinged to both sides of the top of the suspension seat. A storage groove is provided inside the suspension seat. A limiting top block is movably connected inside the storage groove. A bracket is integrally formed at the bottom of the limiting top block. A spring is provided between the bottom of the limiting top block and the bottom inner wall of the storage groove. The top of the limiting block is inverted V-shape and supported between the bottoms of the two opening and closing arms. The bottoms of the two pressure arms are located between the tops of the two opening and closing arms. The bracket is movably connected to the outside of the suspension seat. The ceramic blank is fitted from top to bottom onto the outside of the support head and the two opening and closing arms. Multiple blank fixing components are controlled by a synchronous drive component to flip from the top of the glazing bracket through the blank moving groove to the bottom. The loading and unloading control component controls the loading and unloading of the ceramic blank on the carrying tray outside the multiple blank fixing components.

A second movable groove is provided on the surface of the suspension seat, and a first movable groove is provided between the second movable groove and the storage groove, which is opened inside the suspension seat. The planes where the two limiting arms are located and the planes where the two pressure arms are located are perpendicular to each other. The limiting arms are slidably connected inside the second movable groove, and the limiting heads are slidably connected inside the first movable groove.

[0007] In one possible implementation, rollers are hinged to the bottom of the two pressure arms, and the two rollers are respectively rolled on the opposing surfaces of the two opening and closing arms.

[0008] In one possible implementation, a support column is welded to the bottom inner wall of the storage slot, the spring is sleeved on the outside of the support column, and the limiting top block is slidably connected to the outside of the support column.

[0009] In one possible implementation, counterweights are mounted on the facing surfaces of the bottom of both opening and closing arms, with the opening and closing arms in a vertical position and the counterweights located at the bottom of the hinge point between the opening and closing arms and the suspension seat.

[0010] In one possible implementation, the L-shaped steel member includes a support shaft, one end of which is welded to a first side plate. The U-shaped steel member includes a connecting shaft, both ends of which are welded to second side plates. A common connecting rib is pin-connected between adjacent second side plates on two U-shaped steel members and between the first side plate and the second side plate on an adjacent U-shaped steel member. The connecting rib is located at the end of the first side plate away from the support shaft and at the end of the second side plate away from the connecting shaft. Multiple connecting shafts and support shafts on the same blank fixing assembly are coaxially arranged.

[0011] In one possible implementation, the synchronous drive assembly includes a drive section side frame, with multiple gears arranged on the inner side of the drive section side frame. The multiple gears are respectively pinned to one end of a support shaft on multiple blank fixing assemblies. The support shafts on two adjacent blank fixing assemblies are connected to the same chain through independent gear meshing. One end of one support shaft is assembled and connected to a rotary cylinder. The two ends of the drive section side frame are respectively assembled and fixed at two corners on the side of the glazing bracket away from the loading and unloading control assembly.

[0012] In one possible implementation, two support shafts on one of the blank fixing components are externally interference-fitted with bearings, the bearings are mounted on the top of the glazing bracket or the drive section side frame, the top of the bearings is provided with a bearing seat, and the two ends of the bearing seat are assembled and connected to the top of the drive section side frame or the glazing bracket.

[0013] In one possible implementation: the interior of the support tray has multiple strip grooves, and the top of the support tray has multiple blank positioning grooves; the ends of the multiple strip grooves away from the loading and unloading control components extend to the edge and correspond one-to-one with the multiple blank fixing components; the multiple blank positioning grooves correspond one-to-one with the multiple blank support pieces; and the ceramic blank places the can opening inside the blank positioning groove.

[0014] In one possible implementation, the loading / unloading control component includes a loading / unloading frame, a lead screw rotatably connected to the center of the inner side of the loading / unloading frame, one end of the lead screw passing through the interior of the loading / unloading frame and assembled with a geared motor, a guide crossbar assembled to the inner side of the loading / unloading frame, a lifting platform assembled to the side of the carrying tray near the loading / unloading control component, a hydraulic push rod assembled to the top surface of the lifting platform, the movable end of the hydraulic push rod passing through the interior of the lifting platform and assembled with a translation platform, and a translation plate seat integrally formed at the bottom of the translation platform; The top of each of the four corners of the translation platform is fitted with a guide rod, and the lifting platform is slidably connected to the outside of the four guide rods; the lead screw is threadedly connected to the inside of the translation plate seat, and the translation plate seat is slidably connected to the outside of the two guide crossbars.

[0015] The beneficial effects of this application are as follows: Firstly, in this solution, by placing multiple ceramic blanks with the opening facing down inside multiple blank positioning slots, and using the loading and unloading control components to control the movement of the carrying tray on one side of the lifting platform towards or away from the glazing support, as well as to control the up and down movement of the carrying tray, after multiple ceramic blanks are connected to multiple blank support pieces, the synchronous drive components control multiple blank fixing components to simultaneously flip from the top of the glazing support through the blank movement slot to the bottom, so as to realize the synchronous flipping of the ceramic blanks outside the multiple blank support pieces into the glaze pool, which facilitates the efficient glazing work of a large number of ceramic blanks; Secondly, in this solution, during the movement of the carrying tray to the bottom, pressure is applied to the bracket from top to bottom, which drives the limiting block to move to the bottom and compresses the spring. This releases the top of the limiting block from obstructing the bottom of the two opening and closing arms. With the help of the pressure applied by the ceramic blank on the top of the support head, the two pressure arms apply pressure to the two opening and closing arms through the rollers. This causes the two opening and closing arms to rotate around their hinge point with the suspension seat and move their tops away from each other, pressing against the inner wall of the ceramic blank. This releases the pressure on the multiple brackets, allowing the spring to return to its original position and push the limiting block to the top. The top of the limiting block then presses against the bottom of the two opening and closing arms, preventing the bottoms of the two opening and closing arms from getting close to each other. This helps to ensure that the ceramic blank is stably clamped by the two opening and closing arms. Attached Figure Description

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: This embodiment describes the specific structure of an automatic glazing device for ceramic blanks, as detailed in the following reference. Figures 1-6 As shown, it includes a glazing support 5, a loading and unloading control component 1 disposed on one side of the glazing support 5, and a synchronous drive component 7 disposed on the side of the glazing support 5 away from the loading and unloading control component 1. Multiple blank fixing components 3 are disposed on the top. Each of the multiple blank fixing components 3 includes multiple U-shaped steel parts 303. A blank support 302 is disposed between the tops of two adjacent U-shaped steel parts 303. The multiple U-shaped steel parts 303 are arranged in a line, and L-shaped steel parts 301 are disposed at both ends. Multiple blank movable grooves 8 are opened inside the glazing support 5. The external parts of the multiple blank fixing components 3 are movably connected to the same bearing tray 2. The loading and unloading control component 1 includes a loading and unloading frame 101. A lead screw 103 is rotatably connected to the center of the inner side of the loading and unloading frame 101. One end of the lead screw 103 passes through the interior of the loading and unloading frame 101 and is assembled with a geared motor 102. A guide crossbar 104 is assembled with the inner side of the loading and unloading frame 101. A lifting platform 105 is assembled with the side of the carrying tray 2 near the loading and unloading control component 1. A hydraulic push rod 107 is assembled with the top surface of the lifting platform 105. The movable end of the hydraulic push rod 107 passes through the interior of the lifting platform 105 and is assembled with a translation platform 106. A translation plate seat 109 is integrally formed at the bottom of the translation platform 106. Guide uprights 108 are assembled with the top of the four corners of the translation platform 106. The bearing tray 2 has multiple strip grooves 4 inside and multiple blank positioning grooves 9 on the top. By extending the ends of the multiple strip grooves 4 away from the loading and unloading control components 1 to the edge and corresponding one-to-one with the multiple blank fixing components 3, and the multiple blank positioning grooves 9 corresponding one-to-one with the multiple blank support pieces 302, when the ceramic blank is placed inside the blank positioning groove 9, the movable end of the hydraulic push rod 107 retracts into the fixed end or extends out from the fixed end, so that the lifting platform 105 is slidably connected to the outside of the four guide rods 108. By controlling the lifting platform 105 to move up and down, the ceramic blanks inside the multiple blank positioning grooves 9 are fastened to the top of the blank support piece 302 from top to bottom, and the bearing tray 2 is supported to remove the blanks that have completed the glazing work from the top of the blank support piece 302 through the multiple blank positioning grooves 9, so that the loading and unloading control components 1 control the bearing tray 2 to perform the loading and unloading of ceramic blanks outside the multiple blank fixing components 3. Meanwhile, since the lead screw 103 is threadedly connected inside the translation plate seat 109, and the translation plate seat 109 is slidably connected to the outside of the two guide crossbars 104, by controlling the lifting platform 105 to move left and right, when the ceramic blank is fastened to the top of the blank support 302, the support tray 2 can be removed from between the multiple blank fixing components 3, so that the blank fixing components 3 can rotate on the top of the glazing bracket 5 and flip the ceramic blank to the bottom. like Figure 1 , Figure 4 and Figure 6 As shown, the synchronous drive assembly 7 includes a drive section side frame 702. Multiple gears 701 are arranged on the inner side of the drive section side frame 702. The multiple gears 701 are respectively pinned to one end of the support shaft 3011 on multiple blank fixing assemblies 3. The support shaft 3011 on two adjacent blank fixing assemblies 3 are connected to the same chain 703 through the meshing of independent gears 701. A rotary cylinder 704 is assembled and connected to one end of a support shaft 3011. In this configuration, by mounting and fixing the two ends of the drive section side frame 702 to the two corners of the glazing bracket 5 away from the loading and unloading control component 1, when the rotary cylinder 704 controls the rotation of a single blank fixing component 3 via the support shaft 3011, the gear 701 pinned to the outside of the support shaft 3011 and the chain 703 connected between the support shafts 3011 on two adjacent blank fixing components 3 can be used to support multiple blank fixing components 3 to be controlled by the synchronous drive component 7 to flip from the top of the glazing bracket 5 through the blank movable groove 8 to the bottom.

[0019] In this embodiment, by placing multiple ceramic blanks with the can opening facing down inside multiple blank positioning grooves 9, and by activating the hydraulic push rod 107, its movable end extends out from inside the fixed end, increasing the distance between the bottom of the fixed end and the bottom of the movable end, causing the lifting platform 105 to move upward under the support of four guide rods 108, thereby lifting multiple ceramic blanks on the carrying tray 2 on one side of the lifting platform 105. At the same time, the reducer motor 102 controls the lead screw 103 to rotate, causing the translation plate seat 109 at the bottom of the translation platform 106 to move towards the glazing bracket 5 outside the two guide crossbars 104, thereby driving the lifting platform 105 at the top of the translation platform 106 to move in that direction. After the lifting platform 105 drives the carrying tray 2 to move directly above the glazing bracket 5, the hydraulic push rod 107 controls the lifting platform 105 to reset, driving the carrying tray 2 to move to the bottom, so that multiple ceramic blanks are fastened to the top of multiple blank support pieces 302 to achieve positioning and fixation. Subsequently, the reduction motor 102 controls the lead screw 103 to rotate in the opposite direction. With the help of the translation plate seat 109, the translation plate 106 drives the carrying tray 2 on one side of the lifting plate 105 to move away from the glazing bracket 5. After the carrying tray 2 is completely separated from the outside of the multiple blank fixing components 3 through the multiple strip grooves 4, when the rotary cylinder 704 controls the rotation of a single blank fixing component 3 through the support shaft 3011, the gear 701 pinned to the outside of the support shaft 3011 and the chain 703 connected between the support shafts 3011 on two adjacent blank fixing components 3 can be used to support the multiple blank fixing components 3 to be controlled by the synchronous drive component 7 to flip from the top of the glazing bracket 5 through the blank movable groove 8 to the bottom. This realizes that the ceramic blanks fastened to the outside of the multiple blank support pieces 302 are synchronously flipped into the inside of the glaze pool, which is beneficial for the efficient glazing work of a large number of ceramic blanks.

[0020] Example 2: Based on Example 1, this example describes the specific structure of the blank support 302, such as... Figure 1 , Figures 6 to 11 As shown, the device includes multiple blank support pieces 302, each of which includes a suspension seat 3024. The top of the suspension seat 3024 is provided with a support head 3021. The bottom edge of the support head 3021 is threadedly connected to two pressure arms 3025 symmetrical about its center. The two sides of the top of the suspension seat 3024 are hingedly connected to opening and closing arms 3023. The interior of the suspension seat 3024 is provided with a storage groove 11. The storage groove 11 is movably connected to a limiting top block 3029. The bottom of the limiting top block 3029 is integrally formed with a bracket 3022. A spring 30293 is provided between the bottom of the limiting top block 3029 and the bottom inner wall of the storage groove 11. The top of the limiting block 3029 is inverted V-shaped and supported between the bottoms of the two opening and closing arms 3023. The bottoms of the two pressure arms 3025 are located between the tops of the two opening and closing arms 3023. The bracket 3022 is movably connected to the outside of the suspension seat 3024. When the ceramic blank is fitted from top to bottom onto the outside of the support head 3021 and the two opening and closing arms 3023, the support head 3021 applies pressure to the two opening and closing arms 3023 through the two pressure arms 3025, causing its top to open from the middle to both sides, thereby abutting against the inner wall of the ceramic blank, which can achieve the effect of clamping the ceramic blank. Two limiting arms 3026 are assembled and connected at the bottom edge of the support head 3021. The bottom surfaces of the two limiting arms 3026 facing each other are integrally formed with limiting column heads 3028. A second movable groove 12 is opened on the surface of the suspension seat 3024. A first movable groove 6 is opened inside the suspension seat 3024 between the second movable groove 12 and the storage groove 11. In this way, by making the planes where the two limiting arms 3026 are located and the planes where the two pressure arms 3025 are located perpendicular to each other, when the limiting arms 3026 are slidably connected inside the second movable groove 12, it can be ensured that the two pressure arms 3025 at the bottom of the support head 3021 can move directly up and down on the top of the suspension seat 3024. Meanwhile, when the limiting column head 3028 is slidably connected to the inside of the first movable groove 6, the upper and lower limit lengths of the first movable groove 6 can be used to limit the upper and lower limit distances of the two limiting arms 3026 at the bottom of the support head 3021, so as to prevent the limiting arms 3026 from disengaging from the suspension seat 3024. Secondly, in order to stably support the spring 30293 between the bottom of the limiting top block 3029 and the bottom inner wall of the storage groove 11, such as Figure 10 As shown, a support column 30292 is welded to the bottom inner wall of the storage slot 11. A counterweight 30291 is assembled to the facing surfaces of the bottom of the two opening and closing arms 3023. By having the spring 30293 sleeved on the outside of the support column 30292, when the top of the bracket 3022 is pressed, the limiting top block 3029 is slidably connected to the outside of the support column 30292 and compresses the spring 30293, so that the bottom of the opening and closing arm 3023 is unobstructed, and the tilting state of the opening and closing arm 3023 is controlled by the counterweight 30291. Meanwhile, since the opening and closing arm 3023 is in a vertical state, the counterweight block 30291 is located at the bottom of the hinge point between the opening and closing arm 3023 and the suspension seat 3024. When the bottom of the two opening and closing arms 3023 loses the blocking support of the top of the limiting block 3029, the counterweight block 30291 acts as a counterweight for the opening and closing arm 3023, causing the two opening and closing arms 3023 to rotate around the hinge point between them and the suspension seat 3024, so that the bottoms move away from each other and the tops move closer to each other, allowing the ceramic blank to move up and down outside the blank support 302. Furthermore, to reduce the resistance when the ceramic blank is fitted onto the support head 3021 and the two opening and closing arms 3023 from top to bottom, the support head 3021 applies pressure to the two opening and closing arms 3023 through the two pressure arms 3025, thus reducing the resistance when it opens. Figure 8 and Figure 9 As shown, rollers 3027 are hinged to the bottom of the two pressure arms 3025. By making the two rollers 3027 roll on the opposing surfaces of the two opening and closing arms 3023 respectively, the resistance of the bottom of the pressure arm 3025 relative to the opening and closing arm 3023 when moving can be reduced. In some examples, the L-shaped steel member 301 includes a support shaft 3011, one end of which is welded to a first side plate 3012; the U-shaped steel member 303 includes a connecting shaft 3032, both ends of which are welded to second side plates 3031; and the two adjacent second side plates 3031 on the two U-shaped steel members 303, as well as the first side plate 3012 and the second side plate 3031 on the adjacent U-shaped steel member 303, are all connected by a pin to the same connecting rib 304. Among them, the connecting rib 304 is located at the end of the first side plate 3012 away from the support shaft 3011 and the end of the second side plate 3031 away from the connecting shaft 3032. Multiple connecting shafts 3032 and support shafts 3011 on the same blank fixing assembly 3 are coaxially arranged. When the rotary cylinder 704 controls the support shaft 3011 to rotate through the rotating shaft, the entire blank fixing assembly 3 can be rotated. Meanwhile, in order to mount multiple unglazed blank fixing components 3 on top of the glazing support 5, such as Figure 1 and Figure 6 As shown, two support shafts 3011 on a blank fixing assembly 3 are both interference-fitted with bearings 10. The bearings 10 are installed on the top of the glazing bracket 5 or the drive section side frame 702. The top of the bearings 10 is provided with a bearing seat 305. By assembling the two ends of the bearing seat 305 to the top of the drive section side frame 702 or the glazing bracket 5, the blank fixing assembly 3 can be prevented from disengaging from the top of the glazing bracket 5.

[0021] In this embodiment, multiple blank positioning grooves 9 on the support tray 2 are used to support ceramic blanks and fasten them to the top of multiple blank support pieces 302. During the process of the support tray 2 moving to the bottom, pressure is applied from the top to the bottom to the bracket 3022, and the limiting top block 3029 moves to the bottom to compress the spring 30293, so that the top of the limiting top block 3029 releases the obstruction between the bottoms of the two opening and closing arms 3023, and the bottoms of the two opening and closing arms 3023 release the tendency to move away from each other. At the same time, the top of the support head 3021 is pressed by the ceramic blank, which drives the two pressure arms 3025 to apply pressure to the two opening and closing arms 3023 through the rollers 3027 respectively, causing the two opening and closing arms 3023 to rotate around their hinge point with the suspension seat 3024 and make their tops move away from each other and abut against the inner wall of the ceramic blank, so as to achieve the initial fixation of the ceramic blank by the two opening and closing arms 3023. Subsequently, when the supporting tray 2 detaches from the top of the glazing bracket 5 between the multiple blank fixing components 3 and the pressure on the multiple brackets 3022 is released, the spring 30293 returns to its original position and pushes the limiting block 3029 upward, so that the top of the limiting block 3029 abuts between the bottoms of the two opening and closing arms 3023, restricting the bottoms of the two opening and closing arms 3023 from getting close to each other, and is not affected by the weight of the counterweight 30291 assembled on the opening and closing arms 3023, which helps to ensure the stability of the ceramic blank being clamped and fixed when it rotates with the blank support 302.

[0022] When using this automatic glazing device to glaze ceramic blanks: First, multiple ceramic blanks are placed inside multiple blank positioning slots 9 with the can opening facing down. By activating the hydraulic push rod 107, its movable end extends out from inside the fixed end, widening the distance between the bottom of the fixed end and the bottom of the movable end. This causes the lifting platform 105 to move upward under the support of four guide rods 108, thereby lifting multiple ceramic blanks on the carrying tray 2 on one side of the lifting platform 105. Then, the reduction motor 102 controls the lead screw 103 to rotate, causing the translation plate seat 109 at the bottom of the translation platform 106 to move towards the glazing bracket 5 outside the two guide crossbars 104, thereby driving the lifting platform 105 at the top of the translation platform 106 to move in that direction. Subsequently, after the lifting platform 105 moves the carrying tray 2 to directly above the glazing bracket 5, the hydraulic push rod 107 controls the lifting platform 105 to reset, moving the carrying tray 2 to the bottom. When multiple ceramic blanks are fastened to the top of multiple blank support pieces 302, the carrying tray 2 applies pressure from top to bottom to the bracket 3022, and moves the limiting block 3029 to the bottom to compress the spring 30293. This releases the top of the limiting block 3029 from blocking the bottom of the two opening and closing arms 3023 (in this blocking state, the force point of the two opening and closing arms 3023 is the side of the opening and closing arm 3023 closest to the counterweight block 30291), ensuring that the bottom of the two opening and closing arms 3023 is released from the tendency to move away from each other (the tendency to move away from each other is maintained by the top block 3029 pushing the bottom of the two opening and closing arms 3023 away from each other with the help of the inclined surface). At the same time, the top of the support head 3021 is pressed by the ceramic blank, which drives the two pressure arms 3025 to apply pressure to the two opening and closing arms 3023 through the rollers 3027 respectively, causing the two opening and closing arms 3023 to rotate around their hinge point with the suspension seat 3024, and causing their tops to move away from each other and abut against the inner wall of the ceramic blank. Immediately afterwards, the geared motor 102 controls the lead screw 103 to rotate in the reverse direction, which, with the help of the translation plate seat 109, causes the translation plate 106 to move the carrying tray 2 on one side of the lifting plate 105 away from the glazing bracket 5, and releases the pressure on the multiple brackets 3022. The spring 30293 returns to its original position and pushes the limiting block 3029 upward, so that the top of the limiting block 3029 abuts between the bottoms of the two opening and closing arms 3023, preventing the bottoms of the two opening and closing arms 3023 from getting close to each other (e.g., Figure 11 As shown, in this state, the force point of the two opening and closing arms 3023 is the side of the opening and closing arms 3023 away from the counterweight block 30291, ensuring that the ceramic blank is fixed by the end of the two opening and closing arms 3023 away from the limiting top block 3029. Finally, the rotary cylinder 704 controls the rotation of a single blank fixing assembly 3 via the support shaft 3011. Using the gear 701 pinned to the outside of the support shaft 3011 and the chain 703 connecting the support shafts 3011 on two adjacent blank fixing assemblies 3, multiple blank fixing assemblies 3 are supported by the synchronous drive assembly 7 to flip from the top of the glazing bracket 5 through the blank movable groove 8 to the bottom, synchronously flipping the ceramic blanks fastened to the outside of multiple blank support pieces 302 into the interior of the glaze pool for glazing.
