Description

Technical Field

[0001] This invention relates to the field of dryers, and more specifically to a portable constant temperature dryer. Background Technology

[0002] In existing technologies, after materials complete one processing step, they need to be transported to the next workstation for further processing, especially in drying processes. A common approach is to simultaneously dry the materials during transport. This method involves installing a drying device on the transport equipment, placing the materials into stacked material frames, and connecting the top to a dryer via a drying seal. Hot air is then conveyed downwards from the top stack, drying each material individually. However, existing technologies present a series of problems that urgently need to be addressed.

[0003] First, because hot air is transported from top to bottom, the material in the top stack comes into contact with the hot air first, causing heat to concentrate on the top layer, while the lower layers struggle to receive heat effectively. This is especially true when materials are statically stacked, making it difficult for hot air to penetrate the material layers and flow downwards, resulting in poorer drying performance for materials closer to the bottom. Furthermore, the stacks are typically not sealed, allowing hot air to leak through the gaps. This leakage is exacerbated by shaking during transport, further reducing the utilization rate of hot air and drying efficiency.

[0004] Secondly, the stacking method of the material crates is prone to significant shaking during transportation. As the stacking height increases, the shaking amplitude also increases, leading not only to heat air loss but also making the material crates prone to loosening or even falling off. Therefore, to prevent shaking during transportation, existing technologies often use complex binding and clamping structures to secure the material crates. While this method can reduce shaking, it significantly increases structural complexity and operational difficulty, reducing work efficiency.

[0005] Therefore, there is an urgent need for an improved solution that can effectively increase the utilization rate of hot air, improve the drying effect of materials, and ensure the stability and safety of stacked material frames during transportation. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a portable constant temperature dryer. By employing a drive belt that passes through each material box and, through its linkage with rollers, moves the materials in each box, ensuring continuous movement and better heat transfer. Furthermore, the drive belt pulls down stacked material boxes, compressing them together and effectively preventing shaking and improving stack sealing, thus overcoming the shortcomings of existing technologies.

[0007] This invention is achieved through the following technical solution: a portable constant temperature dryer, comprising:

[0008] A base plate, on the upper end of which a support platform is installed, and material placement surfaces are formed on the base plate on both sides of the support platform. One or more material boxes are stacked on the material placement surfaces in an up-and-down stacking state. A dryer is installed on the upper end of the support platform, and the dryer has a temperature controller.

[0009] One or more drive rollers are provided on both sides of the stacked material boxes. A drive belt is installed between the drive rollers on both sides. The drive belt passes through the stacked material boxes and is installed with the drive rollers. The drive belt divides the storage cavity inside each material box into a first storage cavity and a second storage cavity.

[0010] The drive roller is linked with the roller. When the roller rolls, it drives the drive roller and the drive belt to rotate. The drive belt drives the material located at the upper and lower ends of the drive belt to be in motion.

[0011] It also includes a drying sealing cover, one end of which is sealed and installed on the topmost material box after stacking, and the other end of which is connected to the dryer, which supplies drying gas to the stacked material boxes and discharges it from the bottom of the material boxes;

[0012] Each drive roller is floating, and the drive belt driven by each drive roller presses the stacked material boxes toward the material placement surface.

[0013] As a preferred technical solution, the drive roller includes a first drive roller and a second drive roller. The second drive roller is located on top of each first drive roller. A synchronous belt is installed between the first drive roller and the corresponding upper second drive roller. The two sides of the synchronous belt are respectively installed on synchronous drive wheels on the end faces of the first drive roller and the second drive roller. One end of the first drive roller is connected to the roller. The first drive roller and the roller rotate synchronously, and the synchronous belt and the synchronous drive wheel drive the upper second drive roller to rotate, thereby driving the upper and lower drive belts to rotate.

[0014] The first drive rollers are all floatingly mounted on both sides of the support platform, and the second drive rollers are all floatingly mounted on both sides of a fixed bracket, the bottom of which is fixedly connected to the base plate.

[0015] As a preferred technical solution, a first floating cavity is provided on both sides of the support platform corresponding to the position of the first drive roller. A first floating block is provided in the first floating cavity. A first support spring is provided at the bottom of the first floating block. The first floating block is lifted by the first support spring. A first bearing is installed on the outer end face of the first floating block. One end of the first drive roller is installed in the first bearing.

[0016] As a preferred technical solution, a threaded hole is provided on the upper surface of the support platform corresponding to the position of each first floating cavity, and a threaded clamping rod is provided in each threaded hole. The threaded clamping rod presses down on the first floating block and compresses the first support spring.

[0017] As a preferred technical solution, a second floating cavity is provided on one side of the fixed bracket opposite to the second driving roller, a second floating block is provided in the second floating cavity, a second support spring is provided at the bottom of the second floating block, the second support spring lifts the second floating block, a second bearing is installed on the outer end face of the second floating block, and the second driving roller is installed in the second bearing.

[0018] As a preferred technical solution, through slots are provided on both sides of the material box, and the drive belt passes through the through slots on both sides of the material box respectively. A bottom plate is provided at the bottom of each material box, and ventilation slots are provided on the bottom plate.

[0019] As a preferred technical solution, each material box has an inlet / outlet on its outer side, and a sealing plate is installed at each inlet / outlet. The material is unloaded and loaded by opening the sealing plate.

[0020] As a preferred technical solution, the output end of the dryer is provided with multiple air outlet pipes, each of which is connected to an air supply pipe, and the air supply pipe is connected to the drying sealing cover.

[0021] As a preferred technical solution, a push-pull handle is also installed on the support platform.

[0022] As a preferred technical solution, each drive belt is provided with a closed end, and a locking screw is provided at the closed end. A locking nut is embedded in the closed end of each drive belt. When the two sides of the drive belt are closed and assembled, the closed end of the drive belt is locked by the locking screw. The locking screw is a nut screw.

[0023] The beneficial effects of this invention are as follows: By adopting a drive belt design, the drive belt passes through each material box and is linked with the rollers. With the help of the drive belt, the material in the material box can be in a continuous state of motion. The movement of the material helps to make more full contact with the hot air, enhances the heat transfer effect, improves the problem of uniform drying of each layer of material, and in particular solves the defect of the lower layer of material not being fully dried in the traditional drying method.

[0024] In addition, the drive belt also has the function of pulling down the stacked material boxes, so that the material boxes can be pressed together, effectively preventing the material boxes from loosening and falling off due to shaking during the stacking process. At the same time, this pressing effect significantly improves the sealing of the stacked material boxes, reduces the loss of hot air, and further improves the drying efficiency. In this way, not only is the stability of the drying process guaranteed, but the operating structure is also simplified and work efficiency is improved. Attached Figure Description

Detailed Implementation

[0034] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0035] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0036] like Figure 1 and Figure 2 As shown, a portable constant temperature dryer of the present invention includes a base plate 1, a support platform 2 installed on the upper end of the base plate 1, and material placement surfaces formed on the base plate 1 on both sides of the support platform 2. One or more material boxes 17 are stacked on the material placement surfaces in a stacked manner. A dryer 9 is installed on the upper end of the support platform 2. The dryer 9 has a temperature controller, which can control the output temperature value. That is, a temperature sensor can be set to provide feedback on the current real-time temperature value and control the output temperature at the set temperature value to achieve the purpose of constant temperature. The dryer 9 outputs hot air from the top material box 17 and conveys it downwards to achieve the purpose of stacked drying.

[0037] It also includes one or more drive rollers, which are respectively disposed on both sides of the stacked material boxes 17. A drive belt 8 is installed between the drive rollers on both sides. The drive belt 8 passes through the stacked material boxes 17 and is installed with the drive rollers. The drive belt 8 divides the storage cavity inside each material box 17 into a first storage cavity and a second storage cavity, such as... Figure 4As shown, when placing materials, the materials can be placed in the two storage cavities at the upper and lower ends of the drive belt 8. In this way, the rotation of the drive belt 8 can drive the movement of the materials located at its upper and lower ends, making the original static placement into dynamic placement. This allows hot air to pass through the materials and be conveyed downwards more effectively. In order to allow hot air to pass through the drive belt 8, in this embodiment, gaps are left on both sides of the drive belt 8, which are not the same width as the storage cavities. Of course, multiple ventilation holes can also be provided on the drive belt 8 to allow hot air to pass through the upper and lower ends smoothly.

[0038] The drive roller is linked with the roller 15. When the roller 15 rolls, it drives the drive roller and the drive belt 8 to rotate. The material located at the upper and lower ends of the drive belt 8 is in motion through the drive belt 8. The drive belt 8 can be manually pushed to make the roller 15 roll and drive the drive roller to rotate, thereby driving the drive belt 8 to rotate. Of course, it can also be automated by adding a drive motor to the roller 15 to make the invention electric motion mode.

[0039] It also includes a drying sealing cover 13, one end of which is sealed and installed on the topmost material box 17 after stacking, and the other end of which is connected to the dryer 9. The dryer 9 supplies drying gas to the stacked material boxes 17 and discharges it from the bottom of the material boxes 17. The shape of the sealing cover needs to be aligned with the material boxes 17 for sealing, so its shape can be perfectly matched with the material boxes 17. After alignment, hot air can be delivered downward from the topmost material box 17.

[0040] In this embodiment, as Figure 3 , Figure 5 and Figure 6 As shown, each drive roller is floating. Each drive roller drives the drive belt 8 to press each stacked material box 17 toward the material placement surface. Since the drive belt 8 is set and the drive rollers are all floating, the synchronous belt 11 can be used to pull down each material box 17 at the top, so as to press the material box 17 toward the bottom, effectively preventing shaking during transportation, increasing stability, and preventing the sealing from deteriorating. The tensioning action can be completed by the drive belt 8, simplifying the structure.

[0041] like Figure 1 , Figure 2 as well as Figure 5As shown, the drive roller includes a first drive roller 4 and a second drive roller 24. The second drive roller 24 is located on top of each of the first drive rollers 4. A synchronous belt 11 is installed between the first drive roller 4 and the corresponding upper second drive roller 24. The two sides of the synchronous belt 11 are respectively installed on the synchronous drive wheels 12 on the end faces of the first drive roller 4 and the second drive roller 24. One end of the first drive roller 4 is connected to the roller 15. The first drive roller 4 and the roller 15 rotate synchronously, and the upper second drive roller 24 is driven to rotate by the synchronous belt 11 and the synchronous drive wheel 12, thereby driving the upper and lower drive belts 8 to rotate.

[0042] Among them, such as Figure 3 As shown, the first drive rollers 4 are all floatingly installed on both sides of the support platform 2, and the second drive rollers 24 are all floatingly installed on both sides of a fixed bracket 14. The bottom of the fixed bracket 14 is fixedly connected to the base plate 1. The rotation of the first drive rollers 4 drives the synchronous belt 11 to rotate, and then the synchronous belt 11 drives the second drive rollers 24 at the top to rotate, thereby realizing the linkage movement of each drive belt 8.

[0043] Please continue reading. Figure 3 Each side of the support platform 2 has a first floating cavity 22 corresponding to the position of the first drive roller 4. A first floating block 21 is provided in the first floating cavity 22. A first support spring 23 is provided at the bottom of the first floating block 21. The first support spring 23 lifts the first floating block 21. A first bearing is installed on the outer end face of the first floating block 21. One end of the first drive roller 4 is installed in the first bearing. A threaded hole is provided on the upper end face of the support platform 2 corresponding to the position of each first floating cavity 22. A threaded clamping rod 3 is provided in each threaded hole. The threaded clamping rod 3 presses down on the first floating block 21 and compresses the first support spring 23. A second floating cavity 20 is provided on one side of the fixed bracket 14 opposite to the second drive roller 24. A second floating block 7 is provided in the second floating cavity 20. A second support spring 6 is provided at the bottom of the second floating block 7. The second support spring 6 lifts the second floating block 7. A second bearing is installed on the outer end face of the second floating block 7. The second drive roller 24 is installed in the second bearing.

[0044] After the materials and material box 17 are installed, the threaded clamping rod 3 is manually rotated. At this time, the first floating block 21 is pressed down. Since the first drive roller 4 is installed on the first floating block 21, the pressing down of the first floating block 21 causes the first drive roller 4 to move downward, and the first support spring 23 is compressed. At this time, due to the timing belt 11, the pressing down of the timing belt 11 causes the second drive roller 24, which is connected to the timing belt 11 at the top, to also move downward, and the second support spring 6 is compressed. Figure 6As shown, since each drive belt 8 passes through the material box 17, each material box 17 can move downward and press against each other under the action of the floating block. The pressing degree can be adjusted by the threaded pressing rod 3.

[0045] Each material box 17 has through slots 18 on both sides, through which the drive belt 8 passes. Each material box 17 has a bottom plate 1 with ventilation slots 19. Figure 3 As shown, hot air is input through the top sealing cover and is transferred from top to bottom through the ventilation slots 19 at the bottom of each material box 17. In this embodiment, in order to make the drive belt 8 pass through the through slot 18 more smoothly, ball bearings can be set on the bottom surface of the through slot 18. This will greatly reduce the friction when in contact with the drive belt 8, and make the movement smoother.

[0046] Among them, such as Figure 1 and Figure 2 As shown, each material box 17 has an inlet / outlet on its outer side, and a sealing plate 16 is installed at each inlet / outlet. Material can be unloaded and loaded by opening the sealing plate 16.

[0047] The dryer 9 has multiple air outlet pipes at its output end, and each air outlet pipe is connected to an air supply pipe 10, which is connected to the drying sealing cover 13.

[0048] To facilitate moving the entire device, a push-pull handle 5 is also installed on the support platform 2 in this embodiment. When the device is set to be electrically driven, the push-pull handle 5 can be held by hand to guide the movement.

[0049] To facilitate the replacement or disassembly of the drive belt 8, in this embodiment, each drive belt 8 is provided with a closed end, and a locking screw is provided at the closed end. A locking nut is also embedded in the closed end of each drive belt 8. When the two sides of the drive belt 8 are closed and assembled, the closed end of the drive belt 8 is locked by the locking screw. The locking screw is a mortise screw. By setting the mortise screw, the screw can be flush with the drive belt 8 after being locked in, without affecting the use of the drive belt 8. When disassembling or replacing the drive belt 8, it is only necessary to remove the screw.

[0050] This invention employs a drive belt 8 design, which passes through each material box 17 and is linked with the roller 15. With the help of the drive belt 8, the materials in the material box 17 can be in a continuous state of motion. The movement of the materials helps to make more full contact with the hot air, enhances the heat transfer effect, and improves the problem of uniform drying of materials in each layer. In particular, it solves the defect of the lower layer of materials not being fully dried in traditional drying methods.

[0051] In addition, the drive belt 8 also has the function of pulling down the stacked material boxes 17, so that the material boxes 17 can be pressed together, effectively preventing the material boxes 17 from loosening and falling off due to shaking during the stacking process. At the same time, this pressing effect significantly improves the sealing of the stacked material boxes 17, reduces the loss of hot air, and further improves the drying efficiency. In this way, not only is the stability of the drying process guaranteed, but the operating structure is also simplified and work efficiency is improved.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
