[0001] This invention relates to the field of ceramic product processing technology, and specifically to an adjustable hot air convection drying system for ceramic product processing. Background Technology

[0002] In the processing of ceramic products, the shaped ceramic body needs to be dried. Drying methods can include natural drying or using drying equipment to accelerate the drying process. It is important to ensure the body dries evenly to prevent cracking.

[0003] Traditional ceramic blank drying equipment usually uses hot air convection to accelerate drying efficiency. However, during the hot air convection drying process, the support structure used to support the ceramic blank blocks the bottom surface, resulting in slower drying efficiency at the bottom of the ceramic blank and reducing the overall drying efficiency. Summary of the Invention

[0010] A fixing plate is fixedly installed inside the drying oven;

[0011] Support components are symmetrically arranged on both sides of the fixed plate and are used to drive the movable plate to move up and down.

[0012] The movable plate has a support column array on its top for placing ceramic blanks, and the top of the movable plate has a through hole on the outside of the support column.

[0013] The top of the fixed plate is provided with brackets corresponding to the support column array, and the brackets are slidably disposed on the outside of the support column through through holes.

[0014] Furthermore, the drying chamber is evenly provided with air outlet plates, which are located on the outside of two adjacent columns; the drying chamber is fixedly provided with a support, with partitions evenly distributed on the inner side of the support and toothed plates fixedly provided on the outer side of the partition.

[0015] The support columns are all rotatably mounted on the top of the movable plate, and each support column has a vertical shaft fixedly mounted at its bottom. A toothed column that meshes with the toothed plate is fixedly mounted at the bottom of the vertical shaft. The fixed plate is slidably mounted on the top of the partition plate under the drive of external force.

[0016] Furthermore, L-shaped side plates are fixedly provided on both sides of the fixing plate, and the bottom of the L-shaped side plates is provided with toothed grooves;

[0017] Among them, the outermost two partitions are each provided with gears that cooperate with tooth grooves. The gears are driven by external force to make the fixed plate slide horizontally.

[0018] Furthermore, it also includes inserts for driving the operation of the support assembly, the inserts being rotatably mounted on both sides of the support;

[0019] The support assembly includes an eccentric wheel rotatably mounted on the outside of the L-shaped side plate. A retaining sleeve is fixedly provided at the shaft end of the eccentric wheel, and the retaining sleeve cooperates with the insert block in the horizontal direction.

[0020] The insert block is driven by an external force to rotate the eccentric wheel, triggering the lifting and lowering action of the movable plate.

[0021] Furthermore, the support assembly also includes a connecting block, which is fixedly mounted on the other shaft end of the eccentric wheel. The connecting block is located at the top of the horizontal section of the L-shaped side plate, and an elastic pin is slidably mounted on the outer side of the connecting block.

[0022] The L-shaped side plate has an arc-shaped groove at the top and an insertion hole for inserting a flexible pin at the bottom of the arc-shaped groove; wherein, when the sleeve and the insert block are engaged, the L-shaped side plate triggers the flexible pin to disengage from the insertion hole.

[0023] Furthermore, the insertion hole is provided at the top of one of the tooth grooves, and a slider is slidably provided inside the tooth groove. The slider is pushed upward by the pressure of the gear, and a V-shaped groove for receiving the elastic pin is provided inside the slider.

Finally, the ceramic blank is suspended above the support bracket, and the support column is away from the bottom of the ceramic blank, thus removing the obstruction to the bottom and facilitating the drying of the bottom of the ceramic blank. During the drying process on the side of the ceramic blank, the fixed plate slides inside the drying chamber, causing the support column at the top of the movable plate to rotate the ceramic blank, allowing the ceramic blank to be rotated at different angles to the air outlet for drying. This ensures drying efficiency while achieving uniform drying of the ceramic blank on the side. Attached Figure Description

[0055] The top of the fixed plate 3 is distributed with brackets 31 corresponding to the support column 21. The brackets 31 are slidably set on the outside of the support column 21 through the through hole 22.

[0056] The drying chamber 11 has evenly arranged air outlet plates 110 inside, which are located on the outside of two adjacent rows of support columns 21. The drying chamber 11 has a fixed support 12 inside, with partitions 13 evenly distributed on the inner side of the support 12 and toothed plates 18 fixed on the outer side of the partitions 13. The support columns 21 are all rotatably mounted on the top of the movable plate 2, and the bottom of each support column 21 is fixedly mounted with a vertical shaft 23. The bottom of the vertical shaft 23 is fixedly mounted with a toothed column 24 that meshes with the toothed plate 18. The fixed plate 3 is slidably mounted on the top of the partition 13 by external force. The air outlet plates 110 are all fixedly mounted on the bottom of the top plate 19, which is slidably mounted on the top of the drying chamber 11. The top plate 19 is slidably mounted on the top of the drying chamber 11 by an electric push rod 112 on the outside of the drying chamber 11. The outer side of each air outlet plate 110 is fixedly mounted with an air supply pipe 111 for connecting to a hot air supply device.

[0057] Both sides of the fixed plate 3 are fixedly provided with L-shaped side plates 32, and the bottom of the L-shaped side plates 32 is provided with toothed grooves 323; among them, the outermost two partition plates 13 are provided with gears 14 that cooperate with the toothed grooves 323. The gears 14 are driven by external force to drive the fixed plate 3 to slide horizontally; specifically, there are two gears 14 on the outer side of each partition plate 13. The two gears 14 are linked together through the transmission box A15. The drying box 11 is fixedly provided with a motor A16. The two drive ends of the motor A16 are linked with the gears 14 through the transmission box B17.

The top of the L-shaped side plate 32 is provided with an arc-shaped groove 321, and the bottom of the arc-shaped groove 321 is provided with a socket 322 for inserting the elastic pin 44. When the sleeve 42 and the insert block 51 are engaged, the L-shaped side plate 32 triggers the elastic pin 44 to disengage from the interior of the socket 322.

[0060] The socket 322 is positioned at the top of one of the toothed grooves 323. A slider 33 is slidably mounted inside the toothed groove 323.

[0061] The bracket 31 includes arc-shaped rods A311 and B312 for supporting the ceramic blank; both arc-shaped rods A311 and B312 are located above the movable plate 2, and are kept stable under the support of the fixed plate 3.

[0062] Both ends of the arc-shaped rod A311 are fixedly provided with fixing rods 313, which are fixedly provided on the top of the fixed plate 3. Both ends of the arc-shaped rod B312 are fixedly provided with sliding rods 314, which are slidably provided on the inner side of the fixed plate 3. Limiting blocks A315 and B316 are fixedly provided on the outer side of the sliding rods 314. Limiting blocks A315 and B316 are distributed on the upper and lower sides of the movable plate 2. The sliding rods 314 are slidably installed with the movable plate 2 through damping components 317.

[0063] The principle and advantages of adjustable hot air convection drying systems for ceramic product processing:

[0064] First, the top plate 19 is driven to slide horizontally by the electric push rod 112 to open the top of the drying chamber 11, and the formed ceramic blank is placed on top of the support column 21. Then the top plate 19 is closed, and hot air is introduced into the drying chamber 11 through the air outlet plate 110 at the bottom of the top plate 19, so that the hot air dries the ceramic blank on top of the support column 21 in the form of convection. When the side of the ceramic blank is dried, the movable plate 2 is driven to move downward by the support assembly 4, so that the movable plate 2 moves the support column 21 and the ceramic blank on top downward, and finally the ceramic blank falls on the bracket 31 for support. At this time, the bottom of the ceramic blank is in a suspended state, which removes the obstruction of the bottom surface of the ceramic blank by the support column 21, making the bottom of the ceramic blank easier to dry and improving the overall drying efficiency. It is worth noting that when drying the side of the ceramic blank, the gear 14 inside the support 12 drives L The L-shaped side plate 32 slides back and forth at the bottom of the partition 13, causing the L-shaped side plate 32 to drive the fixed plate 3 and the movable plate 2 to move back and forth. This causes the toothed column 24 connected to the bottom of the support column 21 via the vertical shaft 23 to roll along the toothed plate 18 on the outside of the partition 13, thereby causing the support column 21 to drive the ceramic blank to rotate. This allows the ceramic blank to be rotated at different angles to the air outlet of the air outlet plate 110 for drying, making the drying more efficient and uniform. The gear 14 is driven by the motor A16 on the outside of the drying chamber 11. After the motor A16 starts, it drives the transmission box B17 to run through the two drive ends. This causes the motor A16 to drive one of the gears 14 on both sides to rotate. The gear 14 drives the gear 14 on the same side to rotate through the transmission box A15, achieving synchronous rotation of the two gears 14 in the same direction. This, together with the toothed groove 323 at the bottom of the L-shaped side plate 32, drives the fixed plate 3.

[0065] Its advantages are that, by supporting the ceramic blank with the pillar 21 set on the top of the movable plate 2, after the ceramic blank is dried on the side, the movable plate 2 can be moved downward under the drive of the support component 4, so that the ceramic blank on the top of the pillar 21 falls downward and finally lands on the bracket 31 in a suspended state. At this time, the pillar 21 is away from the bottom of the ceramic blank, thus removing the obstruction to the bottom, so as to facilitate the drying of the bottom of the ceramic blank. In addition, during the drying process of the ceramic blank on the side, by driving the fixed plate 3 to slide inside the drying chamber 11, the pillar 21 on the top of the movable plate 2 drives the ceramic blank to rotate, so as to rotate the ceramic blank at different angles to the air outlet for drying. While ensuring drying efficiency, uniform drying of the ceramic blank on the side is achieved.

[0066] In the adjustable hot air convection drying system for ceramic product processing of this application, during the process of supporting the ceramic blank, when the movable plate 2 moves downward, the movable plate 2 causes the ceramic blank at the top of the support column 21 to fall between the arc-shaped rod A311 and the arc-shaped rod B312 in the bracket 31 for support. At this time, the arc-shaped rod A311 is supported by the fixed rod 313 and is located at a fixed height, and the arc-shaped rod B312 is supported by the sliding rod 314 and maintains a certain height. As the movable plate 2 continues to move downward, the movable plate 2 presses down the limiting block B316 on the outside of the sliding rod 314 and moves it downward, so that the sliding rod 314 drives the arc-shaped rod B312 to move downward slowly. At this time, the ceramic blank located between the arc-shaped rod A311 and the arc-shaped rod B312 begins to tilt, and the bottom of the ceramic blank tilts towards the air outlet, increasing the convection area between the bottom of the ceramic blank and the hot air, thereby achieving rapid drying of the bottom of the ceramic blank.

[0067] Furthermore, after the bottom of the ceramic blank is dried, the drying chamber 11 can be opened by sliding the top plate 19 to remove the ceramic blank supported by the arc rod A311 and arc rod B312. After removal, the movable plate 2 is driven to move upward by the support assembly 4, causing the movable plate 2 to lift the limiting block A315 and drive the sliding rod 314 to move upward. Finally, the arc rod B312 is automatically reset to the outside of the support column 21 and maintains a certain height with the arc rod A311. It is worth noting that when the support assembly 4 drives the movable plate 2 to rise and fall, the motor B52 on the outside of the support 12 drives the insert 51 to rotate, causing the insert 51 to drive the sleeve 42 to rotate, which in turn drives the eccentric wheel 41 to rotate between the movable plate 2 and the fixed plate 3, so that the eccentric wheel 41 can adjust the support height of the movable plate 2, while the eccentric wheel 41 automatically moves downward by its own gravity.

[0068] It is worth noting that the above support methods have the following advantages:

[0069] Firstly, when the movable plate 2 moves downward, it causes the ceramic blank at the top of the support column 21 to fall onto the bracket 31 for support, thus suspending the ceramic blank in mid-air. As the movable plate 2 continues to move downward, it causes the arc-shaped rod B312 to move downward as well. At this time, the ceramic blank located between the arc-shaped rod A311 and the arc-shaped rod B312 gradually tilts, causing the bottom of the ceramic blank to tilt towards the hot air outlet. This increases the bottom drying efficiency by increasing the convection area between the bottom of the ceramic blank and the hot air.

[0070] Secondly, after the ceramic blank is dried at an angle to the bottom, the drying box 11 is opened to unload the material. After unloading, the movable plate 2 is driven upward by the support component 4, so that the movable plate 2 drives the arc rod B312 to automatically return to its original position for reuse.

[0071] Thirdly, by moving the movable plate 2 to position the arc rod B312 at different heights, the height difference between the arc rod A311 and the arc rod B312 can be adjusted to support the ceramic blank at different tilt angles, so as to adapt to the drying work of ceramic blanks of different specifications.

[0072] In practical applications, the drying methods for ceramic blanks are as follows:

[0073] After the ceramic blank is placed on top of the support column 21, the motor A16 drives the gear 14 to rotate, causing the gear 14 to drive the L-shaped side plate 32 to slide on top of the partition plate 13 through the tooth groove 323. This reciprocating sliding motion causes the ceramic blank on top of the support column 21 to rotate, ensuring uniform drying of the ceramic blank's side surface. At this time, the L-shaped side plate 32 drives the outer support component 4 to be positioned between the two inserts 51, preventing the inserts 51 from obstructing the reciprocating movement of the L-shaped side plate 32. Simultaneously, the elastic pin 44 located outside the connecting block 43 is inserted into the insertion hole 322, locking the eccentric wheel 41 to ensure stable support for the movable plate 2, keeping the ceramic blank stable during side drying. After the side surface is dried, the gear 14 drives the L-shaped side plate 32 to move horizontally, causing the L-shaped side plate 32 to drive the retaining sleeve 42 outside the eccentric wheel 41 closer to the insert 51, ultimately engaging with the insert 51 horizontally. At this time, the tooth groove 323 corresponding to the insertion hole 322 is located on top of the gear 14. Furthermore, under the push of the top teeth of gear 14, the slider 33 slides down inside the tooth groove 323, thereby pushing the elastic pin 44 to the top of the insertion hole 322. At this time, the elastic pin 44 is located in the V-groove inside the slider 33. While ensuring that the elastic pin 44 is pushed out of the insertion hole 322, it can prevent the slider 33 from disengaging from the L-shaped side plate 32. When the motor B52 runs, it can synchronously drive the two insertion blocks 51 to rotate through the transmission box C5, so that the insertion blocks 51 drive the eccentric wheel 41 to rotate synchronously in the same direction. After the ceramic blank is removed and unloaded, the L-shaped side plate 32 is driven by the gear 14 to disengage the sleeve 42 from the insert block 51. At this time, the tooth groove 323 corresponding to the insertion hole 322 is away from the bottom of the gear 14. Then, the eccentric wheel 41 is driven to rotate and reset, so that the eccentric wheel 41 pushes the movable plate 2 to automatically reset. At this time, the slider 33 slides into the inside of the tooth groove 323 by its own gravity, and the elastic pin 44 is re-inserted into the inside of the insertion hole 322, so as to automatically lock and support the movable plate 2 before the ceramic blank is loaded.
