Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1A drying device in this embodiment includes a base 1, two left and right groups of support columns 2 are fixed on the top of the base 1, a shell 3 is fixed on the top of the two left and right groups of support columns 2, a heat insulation board 4 is fixed to the bottom of the inner cavity of the shell 3, the heat insulation board 4 is composed of a support block and a partition, the bottom of the partition is fixed to the support block, the bottom of the support block is fixed to the bottom of the inner cavity of the shell 3, the partition is fixed to the inner cavity of the shell 3, four U-shaped heating tubes 5 that are in contact with the heat insulation board 4 are fixed to the inner cavity of the shell 3, and the inner cavity of the shell 3 is provided with two winding components 14 for winding materials.

[0026] Among them, each heating tube 5 is composed of two fixing plates, multiple bolts and a tube body. Each fixing plate is fixed to the side wall of the inner cavity of the shell 3 by bolts. A U-shaped tube body is fixed in the front and rear fixing plates. The U-shaped tube body design increases the contact area between the tube body and the air, which helps to improve the heating effect.

[0027] It should be noted that a servo motor 6 is fixed to the top of the outer shell 3, and the output shaft of the servo motor 6 passes through the inner cavity of the outer shell 3. Ventilation holes 7 are provided at the top of the outer shell 3 and on the left and right sides of the servo motor 6. The setting of the vents 7 ensures the circulation of air and prevents the temperature from being too high and affecting the device. A filter is provided on the inner wall of the vent 7. The filter hinders the entry of impurities and dust to a certain extent, improves the safety of the drying process, and is beneficial to the stable operation of the device. The output shaft of the servo motor 6 is provided with a convection component 8 for increasing the drying rate and enhancing convection. A wind collecting shell 9 is fixed to the left side of the outer shell 3. The wind collecting shell 9 is a trapezoidal structure that is wide on the left and narrow on the right. This design is beneficial to increasing the wind force transmitted from the left side, increasing the gas flow rate, and enhancing the drying effect. The left wall of the inner cavity of the wind collecting shell 9 is provided with an air supply component 10 for supplying a wind source.

[0028] It should also be noted that a stepper motor 11 is fixed to the left side of the top of the base 1, and the output shaft of the stepper motor 11 passes through the inner cavity of the air collecting shell 9 and is fixed to the air supply assembly 10. Two fixed columns 13 are fixed on the left and right sides of the top of the base 1. The fixed columns 13 provide support for the conveying platform 12, which provides a guarantee for its stable operation. Openings for the fixed columns 13 to pass through are provided on the front and rear sides of the air collecting shell 9. The conveying platform 12 is fixed between the front and rear fixed columns 13. The conveying platform 12 is a prior art, and its external power element is not repeated here. The two fixed columns 13 on the left side both pass through the air collecting shell 9, and the conveying platform 12 passes through the air collecting shell 9 and the outer shell 3 from left to right in sequence.

[0029] In this embodiment, the air flow velocity is increased by providing an air supply component 10, and a convection component 8 is provided to blow air downward to generate convection, thereby further accelerating the air flow velocity. Under the action of the winding component 14, the drying time is extended. At the same time, the air collecting shell 9 is designed as a trapezoidal structure, which is beneficial to increase the air flow intensity and improve the drying effect.

[0030] See also Figure 2-3 In order to improve the drying effect of the device, the winding assembly 14 in this embodiment includes a driven roller 1401 and an active roller 1402 which are respectively movably connected between the front and rear side walls of the inner cavity of the shell 3. The winding assembly 14 also includes a guide plate 1403 fixed between the front and rear side walls of the inner cavity of the shell 3. The driven roller 1401 is located at the upper left of the active roller 1402, and a distance suitable for the material is set between the active roller 1402 and the driven roller 1401.

[0031] It should be noted that the material guide plate 1403 is composed of a material receiving block, a material receiving plate and a fixed shaft. The material receiving block is attached to the outer surface of the driven roller 1401. The arched design of the material receiving block is conducive to the stable transmission of materials between the driven roller 1401 and the material receiving plate. The left side of the top of the material receiving plate is fixed to the material receiving block. The material receiving block is penetrated by the fixed shaft and fixed between the front and rear walls of the inner cavity of the outer shell 3 through the fixed shaft. The material receiving plate and the bottom end are attached to the top surface of the conveying platform 12.

[0032] In this embodiment, a winding assembly 14 is arranged on the conveying platform 12, and a distance suitable for the material is set between the active roller 1402 and the driven roller 1401, so that the material can be transmitted on the winding assembly 14, which is beneficial to extending the material transmission path, thereby effectively improving the drying effect.

[0033] Please refer again Figure 1 and Figure 4 In order to improve the drying efficiency, the air supply component 10 in this embodiment includes a driven rod 1002 rotatably connected to the left side of the inner cavity of the air collecting shell 9, and the air supply component 10 also includes an active rod 1001 fixed to the output shaft of the stepping motor 11 and located in the air collecting shell 9. The outer surfaces of the active rod 1001 and the driven rod 1002 are both fixed with rotating wheels 1003, and the outer surfaces of the upper and lower rotating wheels 1003 are transmission-connected with belts, and the right sides of the active rod 1001 and the driven rod 1002 are both fixed with fan blades 1004.

[0034] Furthermore, the driven rod 1002 is rotatably connected to the left side wall of the inner cavity of the air collecting shell 9 via a connecting bearing.

[0035] It is necessary to explain that under the action of the active rod 1001, the driven rod 1002 is driven to rotate through the transmission of the belt, driving the active rod 1001 and the driven rod 1002 through the rotating wheel 1003 to drive the fan blades to operate, thereby delivering air to the right.

[0036] In addition, the convection component 8 includes a rotating shaft 801 fixed to the output shaft of the servo motor 6, and connecting rods 802 are rotatably connected on both sides of the top of the inner cavity of the shell 3. The top of the connecting rod 802 is rotatably connected to the inner top wall of the shell 3 through a fixed bearing, and a transmission component 803 is provided between the rotating shaft 801 and the connecting rod 802.

[0037] Furthermore, the transmission assembly 803 includes a driving wheel fixed on the outer surface of the rotating shaft 801 and a driven wheel fixed on the outer surface of the connecting rod 802. The outer surfaces of the driving wheel and the driven wheel are connected by a transmission belt. A convection fan 804 is fixed to the bottom of the connecting rod 802. The rotating shaft 801 drives the driving wheel to rotate. Under the transmission action of the transmission belt, the driving wheel drives the driven wheel to rotate, thereby causing the convection fan 804 to rotate, so that the convection assembly 8 delivers air downward.

[0038] In this embodiment, under the operation of the air supply component 10, a rightward airflow is generated, and a downward airflow is produced by setting a convection component 8. When the downward airflow intersects with the rightward airflow, convection is generated, which is beneficial to improving the heat exchange of the material. The downward airflow intersects with the upward heat flow generated by the heating tube 5, which is beneficial to slowing down the upward climbing time of the heat flow and increasing the drying temperature during drying, thereby improving the drying effect.

[0039] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0040] The working principle of the above embodiment is:

[0041] (1) The heating tube 5 will release heat after working. The heat insulation board 4 separates the bottom of the shell 3, which produces a heat preservation effect and effectively maintains the temperature inside the shell 3. The temperature inside the shell 3 gradually rises, and the servo motor 6 and the stepper motor 11 are started. The output shaft of the stepper motor 11 drives the active rod 1001 to rotate, thereby driving the rotating wheel 1003 to rotate on the driven rod 1002, thereby driving the fan blades 1004 to work, thereby supplying air to the right. The air collecting shell 9 is a structure that is wide on the left and narrow on the right. As the air collecting shell 9 moves to the right, the wind force will gradually increase, which is conducive to improving the wind force provided by the fan blades 1004 and entering the shell 3 through the opening on the shell 3. At the same time, the output shaft of the servo motor 6 drives the rotating shaft 801, thereby driving the transmission assembly 803 to work, and then the convection fan 804 works. The downward wind force forms convection with the strong wind blowing from the left and the hot air emitted upward from the heating tube 5, stirring the gas flow in the shell 3, enhancing the air flow rate, which is conducive to evaporation and drying, and improving the drying efficiency.

[0042] (2) The material passes through the bottom of the active roller 1402, then passes around the top of the driven roller 1401, and is then transferred to the right along the guide plate 1403. After the material passes through the second winding assembly 14 in the same manner, the conveyor table 12 is started. The material moves to the right along the conveyor table 12, and the material is transferred in sequence along the previously placed positions. In the path of the winding assembly 14, the contact area between the material and the air is increased, thereby extending the drying distance, increasing the drying time, improving the drying effect, and improving the drying efficiency.
