Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and in particular to a ceramic blank drying device for ceramic production. Background Technology

[0002] A ceramic blank drying device is a specialized piece of equipment used in the ceramic production process to safely and evenly remove moisture from a wet blank containing a large amount of water after it has been formed, using controlled hot air and airflow. Its core purpose is not firing (that is done at high temperatures in a kiln), but rather preparing the blank for subsequent trimming, glazing, and final firing. A blank that has not been properly dried is extremely prone to cracking, deformation, or even shattering during firing, resulting in a defective product.

[0003] Existing porcelain blank drying equipment includes suspended dryers. While suspended dryers perform well when processing porcelain blanks of a specific shape, they also have some inherent defects and limitations. For example, once the production line is set to produce plates of a certain size, the entire set of hanging baskets and the suspension spacing are fixed. If it is necessary to switch to producing products of a different size or with a large difference in shape, it is usually necessary to replace the entire set of hanging baskets or make cumbersome mechanical adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic blank drying device for ceramic production, so as to solve the problems mentioned in the background art.

[0005] The present invention relates to a ceramic blank drying device for ceramic production, comprising a circular plate, wherein a plurality of guide openings are provided on the top of the circular plate and arranged in a circular array with the center of the circular plate as the center; an active motor is provided at the center of the top of the circular plate; and a fixed plate is connected to the bottom of the circular plate by a bearing; wherein a plurality of rectangular openings are provided on the bottom of the fixed plate and arranged in a circular array with the center of the fixed plate as the center.

[0006] In one embodiment, the rectangular opening is fitted with a slider, and a connecting rod is fixedly connected to the bottom of the slider. Several connecting rods are arranged in a circular array with the center of the fixed plate as the center.

[0007] In one embodiment, the bottom of the circular plate is provided with several circular boxes, and the upper and lower sides of each circular box are provided with annular openings. The several annular openings are arranged in a circular array with the center of the circular box as the center. A placement plate is fixedly connected to the top of the circular box.

[0008] In one embodiment, the outer side of the circular box has several circular holes, and a movable rod is fitted inside the cavity of each circular hole. A sliding rod is provided through one end of each of the movable rods and is fixedly connected to it. The upper and lower ends of the sliding rod are fitted with the adjacent annular opening.

[0009] In one embodiment, a synchronizing block is fixedly connected to one end of each of the sliding rods that are opposite to each other, and a fixing block is fixedly connected to one side of each of the synchronizing blocks that are opposite to each other, and the fixing block is sleeved on the connecting rod.

[0010] In one embodiment, the fixed block located on the front side is fixedly connected to a lifting plate, and two cranks are hinged to the front side of the lifting plates located on the upper and lower sides. A movable plate is hinged to the corresponding side of each of the two cranks, and the movable plates are hinged to each other.

[0011] In one embodiment, a cylinder is fixedly connected to the bottom of the upper lifting plate.

[0012] The beneficial effects provided by this utility model are:

[0013] 1. Addressing the shortcomings of existing suspended dryers that require replacing the entire basket or performing cumbersome mechanical adjustments when changing products, this device utilizes a transmission structure of "active motor + connecting rod + synchronizing block + moving rod" and a spacing adjustment structure of "cylinder + lifting plate + crank" to achieve dual adaptation adjustment: On one hand, when the active motor drives the circular plate to rotate, the slider slides along the rectangular opening of the fixed plate, driving the connecting rod to move synchronously. Through the synchronizing block and the fixed block, the moving rod and the sliding rod are linked, ultimately expanding or contracting the bearing area of ​​the placement plate; on the other hand, the cylinder drives the upper lifting plate to move, and through the crank, the movable plate folds / unfolds, synchronously adjusting the spacing between multiple sets of placement plates. The entire process requires no replacement of any parts. It can quickly adapt to different sizes (such as large and small plates, tall and short cups) or different shapes (such as bowls, dishes, and bottles) of ceramic blanks through automated drive, perfectly matching the small-batch, multi-variety ceramic production mode and solving the limitation of traditional devices that require "one product, one adaptation".

[0014] 2. This device adopts a "ring array layout + rotary drying" design: the guide opening at the top of the circular plate and the rectangular opening of the fixed plate are arranged in a ring around the center. The placement plates rotate synchronously with the circular plate, ensuring that the ceramic blanks on each placement plate can be evenly exposed to the hot air and airflow in the drying environment. This avoids the problem of localized excessively fast or slow drying of ceramic blanks, which is common in traditional fixed placement methods. Simultaneously, the spacing and area of ​​the placement plates can be adjusted to optimize ventilation gaps according to the size of the ceramic blanks, further ensuring uniform moisture removal. This reduces defects such as firing cracks, deformation, and shattering caused by uneven drying, significantly lowering the scrap rate in ceramic production and improving the quality of the finished product.

[0015] 3. The device replaces traditional manual adjustments with an automated structure: cylinder-driven operation enables "synchronous automated adjustment" of the spacing between the placement plates, eliminating the need for manual adjustment of the mechanical structure one by one; the active motor drives the rotation of the circular plates to automate the drying process, reducing manual intervention. Compared to existing suspended dryers that require manual disassembly, replacement of hanging baskets, or manual adjustment of mechanical spacing, this device significantly reduces the adjustment time for product switching, while also reducing the intensity and skill requirements of manual operation, reducing labor costs, and improving overall production efficiency.

[0016] 4. The key components of the device adopt a "fitting and limiting + synchronous transmission" design: the slider and the rectangular opening of the fixed plate fit tightly together, and the sliding rod and the annular opening of the circular box are precisely matched to ensure that the transmission components such as the connecting rod and the synchronous block move without deviation; the sleeve fit between the fixed block and the connecting rod, and the fixed connection between the synchronous block and the moving rod, realize the synchronous movement of multiple sets of placement plates, avoiding misalignment or shaking of the placement plates during adjustment. This structural design can not only prevent the ceramic blanks from shifting or falling during drying or adjustment, ensuring the integrity of the ceramic blanks, but also improve the structural stability of the device during operation and reduce the risk of production accidents caused by loose components.

[0025] In the first embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown,

[0026] A ceramic blank drying device for ceramic production includes a circular plate 1. The top of the circular plate 1 has several guide openings arranged in a circular array around the center of the circular plate 1. An active motor 2 is installed at the center of the top of the circular plate 1. A fixed plate 7 is connected to the bottom of the circular plate 1 by a bearing. The bottom of the fixed plate 7 has several rectangular openings arranged in a circular array around the center of the fixed plate 7. A slider 8 is attached to each rectangular opening. A connecting rod 6 is fixedly connected to the bottom of the slider 8, and the connecting rod 6 is arranged in a circular array around the center of the fixed plate 7. Several circular boxes 14 are installed at the bottom of the circular plate 1. Circular openings are located on both the top and bottom sides of each circular box 14, and the circular openings are arranged in a circular array around the center of the circular box 14. The top of each circular box 14 is fixedly connected to... There is a placement plate 9. The outer side of the round box 14 has several round holes. The inner cavity of the round holes is fitted with a moving rod 12. One end of each of the moving rods 12 is fitted with a sliding rod 13 and fixedly connected to it. The upper and lower ends of the sliding rod 13 are fitted with adjacent annular openings. One end of each sliding rod 13 opposite to the other is fixedly connected to a synchronizing block 10. One side of each synchronizing block 10 opposite to the other is fixedly connected to a fixing block 11. The fixing block 11 is sleeved on the linkage rod 6. The fixing block 11 on the front side is fixedly connected to a lifting plate 3. Two cranks 5 are hinged to the front side of the lifting plates 3 on the upper and lower sides. One side of each crank 5 is hinged to a movable plate 4. The movable plates 4 are hinged to each other. The bottom of the upper lifting plate 3 is fixedly connected to a cylinder 15.

[0027] Working principle: When the active motor 2 is started, it can drive the circular plate 1 to rotate through the power output shaft. When the circular plate 1 rotates, it can drive the slider 8 to move through the guide port. When the slider 8 moves, it can limit the movement trajectory by fitting with the rectangular opening. When the slider 8 moves, it can drive the connecting rod 6 to move. When several connecting rods 6 move synchronously, they can drive the synchronizing block 10 to move through the fixed block 11. When the synchronizing block 10 moves, it can expand the placement area of ​​the placement plate 9. When the cylinder 15 is started, it can drive the lifting plate 3 located above to move through the power output shaft. When the lifting plate 3 located above moves downward, it can drive the movable plate 4 to fold through the crank 5, thereby realizing the synchronous adjustment of the distance between several placement plates 9.

[0028] In the second embodiment, the components of the ceramic blank drying device for ceramic production are assembled in the following manner:

[0029] Core load-bearing structure: The circular plate 1 is a horizontally set circular metal plate with 6 guide ports evenly opened on its top. The 6 guide ports are arranged in a circular array with the center of the circular plate 1 as the center. A hot air guide net is installed inside the guide port. The active motor 2 is fixed to the center of the top of the circular plate 1 by bolts. The output shaft of the active motor 2 is coaxial with the center of the circular plate 1 and can drive the circular plate 1 to rotate around the center.

[0030] Fixed and transmission connection: The fixed plate 7 is a circular metal plate with the same diameter as the circular plate 1. It is connected to the bottom center of the circular plate 1 through a deep groove ball bearing. The fixed plate 7 remains stationary when the circular plate 1 rotates. The bottom of the fixed plate 7 is evenly provided with 6 rectangular openings, which correspond one-to-one with the 6 guide openings on the top of the circular plate 1. They are all arranged in a ring array with the center of the fixed plate 7. A slider 8 is attached to the inner side of each rectangular opening. The slider 8 is a rectangular metal block. Its bottom is fixedly connected to a connecting rod 6 by welding. The 6 connecting rods 6 extend vertically downward and are distributed in a ring array with the center of the fixed plate 7 as the center.

[0031] The ceramic blank support and adjustment assembly consists of six circular boxes 14 positioned at the bottom of the circular plate 1, corresponding to six guide openings. Each circular box 14 is a hollow cylindrical metal box with annular openings on its upper and lower sides (the diameter of the annular openings is the same as the diameter of the inner wall of the circular box 14). The upper and lower annular openings are aligned in a circular array with the center of the circular box 14 as the center. A placement plate 9, a circular metal plate, is fixedly connected to the top of each circular box 14 by bolts to support the ceramic blank. Four circular holes are evenly distributed on the outer wall of the circular box 14 (the four circular holes are arranged in a circular array with the center of the circular box 14 as the center). A movable rod 12 is attached to the inner side of each circular hole. One end of each rod 12 facing the center of the circular box 14 passes through a sliding rod 13 and is fixed by welding. The sliding rod 13 is an L-shaped metal rod, with its upper and lower ends extending into the annular openings on the upper and lower sides of the circular box 14, respectively, and fitting tightly against the inner side of the annular opening (it can slide along the annular opening). One synchronization block 10 is fixed by welding to the end of each sliding rod 13 away from the center of the circular box 14. The synchronization block 10 is a trapezoidal metal block, and a fixing block 11 is fixed to the side away from the sliding rod 13 by bolts. The fixing block 11 is a rectangular metal block with a through hole, and its through hole is fitted onto the outside of the connecting rod 6 at the corresponding position (it can slide up and down along the connecting rod 6).

[0032] Spacing drive assembly: A fixed block 11 located on the front side (corresponding to the guide opening position on the front side of the circular plate 1) is fixedly connected to a lifting plate 3 by welding. The lifting plate 3 is a vertically arranged rectangular metal plate. There are two lifting plates 3 in the vertical direction (corresponding to the upper and lower positions of the linkage rod 6 respectively). The front side of each lifting plate 3 is hinged to two cranks 5 by a pin. The two cranks 5 are metal rods of the same length and are symmetrically distributed on both sides of the lifting plate 3. The two corresponding cranks 5 (the left crank 5 of the upper lifting plate 3 and the left crank 5 of the lower lifting plate 3) are hinged to a movable plate 4 by a pin at their ends facing each other. The four movable plates 4 (corresponding to four sets of cranks 5) are hinged to each other by pins to form a foldable / unfoldable linkage structure. A cylinder 15 is fixedly connected to the bottom of the upper lifting plate 3 by bolts. The cylinder 15 is set vertically downward. The bottom of its piston rod is welded and fixed to the top of the lower lifting plate 3, which can drive the upper and lower lifting plates 3 to move closer or further away in the vertical direction.

[0033] II. Taking the drying operation of a ceramic disc with a diameter of 20cm as an example

[0034] Step 1: Adjust the load-bearing area of ​​the placement plate

[0035] Start the active motor 2. The output shaft of the active motor 2 drives the circular plate 1 to rotate clockwise around its center (the speed is set to 5 r / min). When the circular plate 1 rotates, it drives the slider 8 to slide away from the center along the rectangular opening at the bottom of the fixed plate 7 through the connecting rod 6 (the rectangular opening restricts the slider 8 to move only radially). When the slider 8 moves, the connecting rod 6 drives the fixed block 11 to move away from the center. The fixed block 11 pushes the slide rod 13 to slide outward along the annular opening of the circular box 14 through the synchronizing block 10. The slide rod 13 then drives the moving rod 12 to extend outward along the circular hole of the circular box 14. When the extension length of the moving rod 12 reaches 5 cm, the active motor 2 is turned off. At this time, the effective bearing diameter of the placement plate 9 is expanded to 22 cm (greater than the ceramic disc diameter of 20 cm), which can stably support the ceramic disc.

[0036] Step 2: Adjust the vertical spacing of the placement board

[0037] The piston rod of the control cylinder 15 retracts, and the cylinder 15 drives the upper lifting plate 3 to move downward. The upper lifting plate 3 pulls the movable plate 4 to fold through the cranks 5 on both sides, and the movable plate 4 in turn drives the lower lifting plate 3 to move upward. When the distance between the upper and lower lifting plates 3 is reduced to 25cm, the cylinder 15 is closed. At this time, the distance between the two adjacent upper and lower placement plates 9 is 25cm (greater than the thickness of the ceramic disc by 3cm, to ensure that the hot air can circulate fully).

[0038] Step 3: Drying Operation

[0039] A wet ceramic disc with a diameter of 20cm was placed one by one on six placement plates 9. The hot air system was turned on, and the hot air entered the device through the guide port at the top of the disc 1, passed through the annular opening and the circular hole of the disc 14, and acted evenly on the surface of the ceramic disc. At the same time, the active motor 2 was turned on to keep the disc 1 rotating at a speed of 5r / min, so that the ceramic disc on each placement plate 9 could be in contact with the hot air 360°, avoiding uneven drying in some areas. The drying time was set to 2 hours. During this period, the internal temperature of the device was monitored by a temperature sensor and kept at 80℃±5℃. Finally, the ceramic disc was dried evenly, and there were no cracks or deformations in the dried ceramic disc.

[0040] III. Taking the drying process of switching to a ceramic cup with a height of 15cm and a diameter of 8cm as an example

[0041] Step 1: Quickly adjust the load-bearing area of ​​the placement plate

[0042] Without disassembling any parts, simply start the active motor 2 and control the output shaft of the active motor 2 to drive the circular plate 1 to rotate counterclockwise (speed set to 3r / min). When the circular plate 1 rotates counterclockwise, the connecting rod 6 drives the slider 8 to slide along the rectangular opening of the fixed plate 7 towards the center. The fixed block 11 moves towards the center with the connecting rod 6. The synchronizing block 10 pulls the sliding rod 13 to slide inward along the annular opening of the circular box 14. The moving rod 12 retracts into the circular box 14 along the circular hole. When the moving rod 12 retracts to only 1cm protruding, the active motor 2 is turned off. At this time, the effective bearing diameter of the placement plate 9 is reduced to 10cm (suitable for the bottom diameter of the ceramic cup of 8cm), which can stably support the ceramic cup.

[0043] Step 2: Adjust the vertical spacing of the placement board

[0044] The piston rod of the control cylinder 15 extends, and the cylinder 15 pushes the upper lifting plate 3 to move upward. The upper lifting plate 3 pushes the movable plate 4 to unfold through the crank 5. The movable plate 4 drives the lower lifting plate 3 to move downward. When the distance between the upper and lower lifting plates 3 increases to 40cm, the cylinder 15 is closed. At this time, the distance between the upper and lower adjacent placement plates 9 is 40cm (greater than the height of the ceramic cup by 15cm, to avoid the top of the ceramic cup from contacting the upper placement plate 9, while ensuring that hot air can circulate around the ceramic cup).

[0045] Step 3: Drying Operation

[0046] One by one, wet ceramic cups (mouth facing up) with a height of 15cm and a diameter of 8cm were placed on the six placement plates 9. The hot air system was started, and the hot air entered through the guide port and formed a surrounding airflow through the annular opening and circular hole of the circular box 14, acting on the inner and outer walls of the ceramic cups. The active motor 2 was started, and the circular plate 1 was kept rotating at a speed of 8r / min (the ceramic cups are relatively tall, so the speed was appropriately increased to ensure that the upper and lower parts are dried evenly). The drying time was set to 2.5h, and the internal temperature of the device was kept at 75℃±5℃ during the period. After drying, the ceramic cups showed no cracks in the inner wall or deformation of the mouth, which met the requirements for subsequent trimming and glazing.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
