Description

Technical Field

[0001] The invention relates to the field of drying machines, and in particular to a movable constant-temperature drying machine. Background Art

[0002] In the prior art, after a material is processed in one process, it needs to be transported to the next station for further processing, especially in the drying process. Usually, the method of completing the drying during the transportation process is widely used. In this method, a device with a drying function is set on the transportation equipment, and the materials are placed in the material frame and stacked. The top is connected to the dryer through a drying sealing cover, so that hot air is transported downward layer by layer from the top material frame, so that the materials are dried one by one. However, there are a series of problems in the prior art that need to be solved.

[0003] First, because the hot air is transported from top to bottom, the materials in the top material frame are the first to come into contact with the hot air, resulting in the heat being concentrated on the topmost material, while the lower material cannot effectively receive the heat. Especially when the materials are statically stacked, it is difficult for the hot air to penetrate the material layer and transport downward, resulting in the worse drying effect for the materials closer to the bottom. In addition, the material frames are usually not sealed, and hot air can easily leak from the stacking gaps, especially during transportation, when shaking can easily cause heat loss, further reducing the utilization rate of the hot air and the drying efficiency.

[0004] Secondly, the stacking method of the material frames is prone to large shaking during transportation. As the stacking height increases, the shaking amplitude also increases, which not only causes hot air loss, but also easily causes the material frames to loosen or even fall. Therefore, in order to prevent the shaking problem during transportation, the existing technology often uses a complex binding and compression structure to fix the material frames. Although this method can reduce shaking, it significantly increases the structural complexity and operation difficulty, and reduces work efficiency.

[0005] Therefore, the prior art urgently needs an improved solution that can effectively improve the utilization rate of hot air, improve the material drying effect, and ensure the stability and safety of the stacking material frame during transportation. Summary of the invention

With the help of the linkage with the roller, the driving belt is used to drive the materials in each material box, so that each material can be constantly in a state of motion, and can be better transferred with the hot air and transferred downward. The driving belt can be used to pull down the stacked material boxes, so that the material boxes can be pressed against each other, effectively preventing the material boxes from shaking after being stacked, improving the stacking sealing, and effectively solving the shortcomings of the prior art.

[0035] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0036] like Figure 1 and Figure 2 As shown, a movable constant temperature dryer of the present invention comprises a bottom plate 1, a support table 2 is installed on the upper end of the bottom plate 1, a material placement surface is formed on the bottom plate 1 on both sides of the support table 2, and more than one material box 17 is stacked up and down and sequentially stacked on the material placement surface, and a dryer 9 is installed on the upper end surface of the support table 2. The dryer 9 has a temperature controller, and the output temperature value can be controlled by the temperature controller, that is, a temperature sensor can be set to feedback the current real-time temperature value, and the output temperature is controlled at the set temperature value to achieve the purpose of constant temperature. The dryer 9 outputs hot air from the topmost material box 17 to the bottom, so as to achieve the purpose of stacking and drying;

[0037] It also includes one or more driving rollers, which are arranged on both sides of the stacked material boxes 17, and driving belts 8 are installed between the driving rollers on both sides. The driving belts 8 pass through the stacked material boxes 17 and are installed with the driving rollers. The driving belts 8 divide 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 material storage cavities at the upper and lower ends of the driving belt 8, so that the rotation of the driving belt 8 can drive the movement of the materials at the upper and lower ends thereof, so that the original static placement is changed to dynamic placement, so that the hot air can better pass through the materials and be transported downward. In order to allow the hot air to pass through the driving belt 8, in this embodiment, gaps are respectively left on both sides of the driving belt 8, which are not as wide as the material storage cavities. Of course, a plurality of air holes can also be provided on the driving belt 8 to allow the hot air to pass through the upper and lower ends smoothly.

[0038] The driving roller is linked with the roller 15. When the roller 15 rolls, it drives the driving roller and the driving belt 8 to rotate. The driving belt 8 drives the materials at the upper and lower ends of the driving belt 8 to move. The driving belt 8 can manually push the entire device so that the roller 15 rolls and drives the driving roller to rotate, thereby driving the driving belt 8 to rotate. Of course, the present invention can also be transformed into an electric motion mode by installing a driving motor on the roller 15 in an automated manner.

The shape of the sealing cover needs to be docked and sealed with the material box 17, so its shape can just match the material box 17. After docking, hot air can be transported downward from the top material box 17;

[0040] In this embodiment, if Figure 3 , Figure 5 and Figure 6 As shown, each driving roller is in a floating arrangement, and each driving roller drives the driving belt 8 to press each stacked material box 17 toward the material placement surface. Since the driving belt 8 is provided and the driving rollers are in a floating arrangement, the synchronous belt 11 can be used to pull down each material box 17 at the top, so as to achieve the purpose of pressing the material box 17 toward the bottom, effectively preventing shaking during transportation, increasing stability, and preventing the occurrence of poor sealing. The driving belt 8 can be used to complete the tensioning action and simplify the structure.

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

[0042] Among them, Figure 3 As shown, the first driving rollers 4 are floatingly mounted on both sides of the support platform 2, and the second driving rollers 24 are floatingly mounted 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 driving roller 4 drives the synchronous belt 11 to rotate, and then the synchronous belt 11 drives the top second driving roller 24 to rotate, thereby realizing the linkage movement of each driving belt 8.

[0043] Please continue reading Figure 3 , first floating cavities 22 are provided at positions corresponding to the first driving roller 4 on both sides of the support platform 2, a first floating block 21 is provided in the first floating cavity 22, a first supporting spring 23 is provided at the bottom of the first floating block 21 to support the first floating block 21, the first supporting spring 23 lifts up the first floating block 21, a first bearing is installed on the outer end surface of the first floating block 21, one end of the first driving roller 4 is installed in the first bearing, a threaded hole is provided at the position corresponding to each first floating cavity 22 on the upper end surface of the support platform 2, a threaded clamping rod 3 is provided in the threaded hole, the threaded clamping rod 3 presses down the first floating block 21 and compresses the first supporting spring 23, a second floating cavity 20 is provided on one side of the fixed bracket 14 opposite to the second driving roller 24, a second floating block 7 is provided in the second floating cavity 20, a second supporting spring 6 is provided at the bottom of the second floating block 7, the second supporting spring 6 lifts up the second floating block 7, a second bearing is installed on the outer end surface of the second floating block 7, and the second driving roller 24 is installed in the second bearing.

[0044] When the material and the material box 17 are installed, the threaded pressing rod 3 is manually rotated, and the first floating block 21 is pressed down. Since the first driving roller 4 is installed on the first floating block 21, the first floating block 21 is pressed down to make the first driving roller 4 move downward, and the first supporting spring 23 is compressed. At this time, since the synchronous belt 11 is set, the second driving roller 24 connected to the synchronous belt 11 at the top also moves downward under the downward pressure of the synchronous belt 11, and the second supporting spring 6 is compressed. Figure 6As shown, since each driving belt 8 passes through the material box 17, under the action of the floating block, each material box 17 can move downward and press each other, and the degree of compression can be adjusted by the threaded compression rod 3.

[0045] The two sides of the material box 17 are provided with through grooves 18, and the driving belt 8 passes through the through grooves 18 on both sides of the material box 17 respectively. The bottom of each material box 17 is provided with a bottom plate 1, and the bottom plate 1 is provided with ventilation grooves 19. Figure 3 As shown, hot air is input through the sealing cover at the top, and the hot air is transferred from top to bottom through the ventilation grooves 19 at the bottom of each material box 17. In this embodiment, in order to allow the driving belt 8 to pass through the through grooves 18 more smoothly, balls can be arranged on the bottom surface of the through grooves 18, so that the contact with the driving belt 8 can greatly reduce the friction and make the movement smoother.

[0046] Among them, Figure 1 and Figure 2 As shown, each material box 17 is provided with an inlet and outlet on the outer side, and a sealing plate 16 is installed at each inlet and outlet, and unloading and loading are performed by opening the sealing plate 16.

[0048] In order to facilitate the movement of the entire device, in this embodiment, a push-pull handle 5 is also installed on the support platform 2. When the device is set to be driven electrically, the push-pull handle 5 can be held to perform guided movement.

[0049] In order to facilitate the replacement of the drive belt 8 or the removal of the drive belt 8, in the present embodiment, the drive belt 8 is provided with a closed end, and a locking screw is provided at the closed end. The closed ends of the drive belt 8 are embedded with locking nuts. When the two sides of the drive belt 8 are closed and assembled, the closed ends of the drive belt 8 are locked by the locking screws. The locking screws are machine screws. By providing the machine screws, the screws can be flush with the drive belt 8 after being locked, without affecting the use of the drive belt 8. When removing or improving the drive belt 8, it is only necessary to remove the screws.

[0050] The present invention adopts the design of a driving belt 8, which passes through each material box 17 and is linked with the roller 15. With the help of the driving belt 8, the material in the material box 17 can be in a continuous motion state. The movement of the material helps to more fully contact with the hot air, thereby enhancing the heat transfer effect, improving the uniform drying of each layer of material, and especially solving the defect that the lower layer of material cannot be fully dried in the traditional drying method.

[0051] In addition, the driving belt 8 also has the function of pulling down the stacked material boxes 17, so that the material boxes 17 can be pressed against each other, effectively preventing the material boxes 17 from loosening and falling 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 the stability of the drying process is ensured, but also the operating structure is simplified and the work efficiency is improved.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
