[0003] A search revealed a Chinese patent with authorization number CN216204846U, which discloses a constant temperature drying device, including a base, a rack, a first pulley, a second swing rod, and a lifting platform. The top of the base is provided with a gear that drives the rack to slide. The top of the rack is fixedly connected to a transmission rod that drives the first pulley to slide. The surface of the first pulley is rotatably connected to a first swing rod that drives the second swing rod to swing.

[0032] Example:
[0033] Reference Figures 1-8 A constant temperature drying device for rapid demolding of wet blanks includes a constant temperature structure 100, a constant temperature base 101, and a receiving box 102 fixedly connected to the constant temperature base 101.
[0034] The adjustment structure 200 includes a guide rail 201 fixedly connected to the surface of the receiving box 102, a shelf 202 slidably connected to the surface of the guide rail 201, and an adjustment component 203 fixedly connected to the surface of the shelf 202.
[0035] The guide structure 300 includes a mounting plate 301 fixedly connected to the surface of the guide rail 201, a support base 302 fixedly connected to the surface of the mounting plate 301, and a guide assembly 303 movably connected to the mounting plate 301. By setting up the constant temperature structure 100, the adjustment structure 200, and the guide structure 300, efficient and uniform drying of the wet blank can be achieved. Specifically, the constant temperature structure 100 provides a stable thermal environment, the adjustment structure 200 allows for flexible adjustment of the position of the placement plate 202, and the guide structure 300 ensures the stability and accuracy of the placement plate 202 during movement. In use, the user can adjust the position of the placement plate 202 according to the size and shape of the wet blank using the adjustment assembly 203 to achieve the best drying effect.
[0036] The adjusting assembly 203 includes a rack 205 fixedly connected to the surface of the shelf 202, a spur gear 206 meshing with the surface of the rack 205, a drive shaft 207 fixedly connected to the surface of the spur gear 206, and a retaining ring 209 fixedly connected to one end of the drive shaft 207. By setting the adjusting assembly 203, the position of the shelf 202 can be controlled. The meshing connection between the rack 205 and the spur gear 206 allows for simple rotational movement of the shelf 202, simplifying operation. The design of the drive shaft 207 and the retaining ring 209 ensures the stability and reliability of the transmission.
[0037] A fixed sleeve 208 is rotatably connected to the surface of the drive shaft 207, and the fixed sleeve 208 is fixedly connected to the surface of the receiving box 102. A fixed ring 209 is rotatably connected to the surface of the fixed sleeve 208. A positioning cylinder 214 is fixedly connected to the surface of the receiving box 102, and the surface of the positioning cylinder 214 has positioning holes 215 arranged in a circular pattern. By setting the fixed sleeve 208, positioning cylinder 214, and positioning holes 215 on the surface of the drive shaft 207, the position of the shelf 202 can be quickly positioned and fixed. The fixed connection between the fixed sleeve 208 and the receiving box 102, and the rotatable connection between the fixed ring 209 and the fixed sleeve 208, ensure the stable rotation of the drive shaft 207. The design of the positioning cylinder 214 and the positioning holes 215 allows users to quickly fix the shelf 202 in multiple preset positions, improving the convenience and efficiency of operation.
[0038] A rotating shaft 210 is fixedly connected to the surface of the fixing ring 209. A groove 211 is formed on the inner surface of the rotating shaft 210. A slider 212 is slidably connected to the surface of the groove 211. A push-pull rod 213 is fixedly connected to the surface of the slider 212. A handle 216 is fixedly connected to one end of the push-pull rod 213. A positioning block 217 is fixedly connected to the surface of the handle 216. By setting the rotating shaft 210, groove 211, slider 212, push-pull rod 213, handle 216, and positioning block 217 on the surface of the fixing ring 209, flexible adjustment and rapid positioning of the shelf 202 can be achieved. The groove 211 and push-pull rod 213 make the movement of the handle 216 smoother, and the positioning block 217 fixed in the positioning hole 215 ensures the stability of the handle 216 when it is in a fixed position.
[0039] The surface of the placement plate 202 has a groove 218, and the inside of the groove 218 is fitted with a linear array of rolling balls 219. By setting the groove 218 and the rolling balls 219 on the surface of the placement plate 202, the friction of the placement plate 202 when moving in the guide rail 201 can be significantly reduced, making the placement plate 202 more stable during movement and reducing the risk of sample damage.
[0040] Reference Figures 1-9Furthermore, the guide assembly 303 includes a guide hole 304 formed on the mounting plate 301, a limiting block 312 fixedly connected to the support base 302, a first guide post 305 slidably connected to the surface of the guide hole 304, a second guide post 306 slidably connected to the surface of the first guide post 305, a second connecting rod 308 rotatably connected to the surface of the first guide post 305, and a first connecting rod 307 rotatably connected to the surface of the second guide post 306. By setting the guide assembly 303, guidance and stable support can be achieved during the movement of the shelf 202. The design of the guide hole 304 and the limiting block 312 ensures the stability of the first guide post 305 and the second guide post 306 during movement, avoiding deviation and swaying. The sliding connection of the first guide post 305 and the second guide post 306, and the rotatable connection of the second connecting rod 308 and the first connecting rod 307, form a flexible linkage mechanism that can automatically adjust its position according to the movement of the shelf 202, ensuring the stability and accuracy of the shelf 202 during movement.
[0041] The surface of the first guide post 305 has a first arc-shaped groove 309, and the surface of the second guide post 306 has a second arc-shaped groove 310. A connecting block 311 is movably connected at the translational intersection of the first arc-shaped groove 309 and the second arc-shaped groove 310. By setting the first arc-shaped groove 309 of the first guide post 305 and the second arc-shaped groove 310 of the second guide post 306, and movably connecting the connecting block 311 at their translational intersection, the movement path of the shelf 202 can be controlled. The arc-shaped groove design allows the guide post to move non-linearly within a certain range, thus guiding the movement of the shelf 202.
[0042] Specifically, in operation, this constant temperature drying device for rapid demolding of wet blanks has three vertically arranged storage plates 202. Initially, the three storage plates 202 are all on the same central vertical line. A rotating handle 216 is located on the side of the constant temperature drying device to control the uppermost storage plate 202. The uppermost storage plate 202 and the rotating handle 216 are connected via a spur gear 206 meshing with a rack 205. Pulling the push rod 213 causes the positioning block 217 on the handle 216 to move out of the positioning hole 215. When the rotating handle 216 is rotated, the spur gear 206 at one end of the rotating handle 216 passes through the strip groove 204 on the guide rail 201, driving the gear... The movement of bar 205 will cause the uppermost shelf 202 to move into the receiving cavity. The uppermost shelf 202 and the second shelf 202 are connected by a guide assembly 303. During the movement, the uppermost shelf 202 is connected to the first guide post 305 via the second connecting rod 308. The second guide post 306 is connected to the second shelf 202 via the first connecting rod 307. Similarly, the guide assembly 303 between the second shelf 202 and the bottom shelf 202 is in the opposite direction to the guide assembly 303 between the uppermost shelf 202 and the second shelf 202. When the uppermost shelf 202 moves into the receiving cavity... The top shelf 202 moves the first guide post 305 in the same direction as the top shelf 202 via the second connecting rod 308. Under the action of the first arc-shaped groove 309, the second arc-shaped groove 310, and the connecting block 311, which is movably connected at the intersection of the first and second arc-shaped grooves 309 and 310, but with one end fixed to the surface of the second guide post 306, the first guide post 305 moves in the opposite direction to the second guide post 306. The second shelf 202 moves along the opening of the receiving cavity, and this movement causes the bottom shelf 202 to move along the second shelf 202. The direction of the bottom shelf 202 is staggered with that of the second shelf 202, meaning the bottom shelf 202 moves a greater distance than the second shelf 202. This achieves a staggered arrangement of the three shelves 202, ensuring a uniform temperature distribution within the container 102. The moving shelves 202 also create rotating eddies, which helps maintain a constant pressure within the cavity. The operator observes the wet blank samples on each shelf 202. After adjusting the three shelves 202 by turning handle 216, the operator pushes the push-pull rod 213 to move the positioning block 217 into the positioning hole 215, keeping the three shelves 202 in their adjusted state.
[0043] The three-layer placement plate 202 achieves cross-movement through the guide structure 300, causing hot air to form turbulence between the layers, forcing convection to penetrate the sample gaps, eliminating local overheating or underheating caused by fixed paths. During the movement of the placement plate 202, the interlayer spacing changes periodically, causing hot air to form a circulating vortex in the vertical direction. Combined with the horizontal displacement, a three-dimensional dynamic temperature field is constructed, significantly improving the uniformity of temperature distribution. The placement plate 202 is translated instead of rotated, and the linear motion reduces airflow disturbance. At the same time, the impact of the translation plate on the existing vortex can break up local low-pressure areas and maintain the pressure balance of the inner cavity.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
