[0058] To fully understand the present invention, the following specific embodiments, in conjunction with the accompanying drawings, will provide a detailed description. Those skilled in the art can understand the purpose, features, and effects of the present invention from the content disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the inventive point of the present invention. Furthermore, the accompanying drawings are for simple illustrative purposes only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the claims of the present invention. The following explanation is provided:

[0059] like Figures 1 to 4 As shown, the drying device 100 of this embodiment of the invention includes: a conveyor belt 1, an airflow blowing mechanism 2, and a separating component 3.

[0060] The conveyor belt 1 has a conveying surface 11 and a conveying direction d. The conveying surface 11 is for placing materials S (e.g., screws) and conveying them along the conveying direction d. The conveyor belt 1 can be a conveyor track, conveyor belt, or other mechanism for conveying materials.

[0061] The airflow blowing mechanism 2 includes a housing 21, two blowers 22, two air distribution modules 23, and at least one heater 24.

[0062] The housing 21 covers the conveyor surface 11 and clamps with the conveyor belt 1 to form a drying space F.

[0063] Two blowers 22 are respectively located on both sides of the conveyor belt 1 and upstream in the conveying direction d, that is, the upstream part of the connecting housing 21. Each of the two blowers 22 corresponds to two air distribution modules 23, and blows airflow toward the drying space F through the two air distribution modules 23.

[0064] Two air distribution modules 23 are respectively arranged on both sides of the conveyor belt 1 in parallel with the conveying direction d. The function of the air distribution module 23 is to transmit the air blown in one direction from the blower 22 (upstream of the conveying direction d, towards the positive and negative X-axis) in the X and Y directions at the same time, so as to uniform and refine the strong airflow generated by the blower 22, so that there is uniform airflow throughout the entire conveying direction d, and the airflow in the drying space F has a similar intensity.

[0065] At least one heater 24 is disposed between one of the blowers 22 and one of the air distribution modules 23. The heater 24 is used to heat the airflow generated by the blower 22.

[0066] The separating member 3 is positioned parallel to the conveying direction d in the drying space F, dividing the drying space F into two parts. In other words, through the separating member 3, two blowers 22, and two air distribution modules 23, the drying space F can independently perform two different temperature drying operations without mixing the airflows of different temperatures on both sides of the separating member 3. The drying space F can utilize at least one heater 24 to heat the airflow on one side of the separating member 3, enabling simultaneous high-temperature drying and cold air / normal temperature drying operations on the conveyor belt 1.

[0067] like Figure 2 As shown, the housing 21 also has two return channels R, located on both sides of the drying space F. The first end R1 of the return channel R is connected to the blower 22, and the second end R2 of the return channel R is connected to one side of the drying space F downstream in the conveying direction d. The function of the return channels R is to return the airflow in the drying space F downstream in the conveying direction d to the blower 22, so as to recycle and reuse the heated airflow and reduce the energy consumption of the heater 24.

[0068] In summary, the drying apparatus 100 of the present invention can simultaneously perform hot air drying and cold air / room temperature drying processes on a single conveyor belt 1, and the flow fields of each process will not mix, which helps to improve the quality and efficiency of drying. In addition, the air distribution module 23 can uniformize and refine the strong airflow generated by the blower 22, so that there is uniform airflow along the entire conveying direction d, and the airflow in the drying space F has similar intensity. Compared with the existing drying apparatus, which only has airflow near the blower outlet, the drying apparatus 100 of the present invention allows each material S in the process to be blown by the same and stable airflow, so that the dried finished product can be homogenized, which helps to improve the uniformity of product quality.

[0069] Further, as shown in FIG. 6, in the present embodiment, the uniform air module 23 is a cylindrical passage parallel to the conveying direction d. The uniform air module 23 has an air outlet 234 facing the drying space F, and the cross section of the uniform air module 23 is tapered in the direction facing the drying space F (positive and negative X-axis directions). Figure 3

[0070] In the present embodiment, as shown in FIG. 6, the height of the air outlet 234 corresponds to the tooth portion of the screw, and the drying effect can be particularly enhanced for the tooth portion of the screw. Figure 4

[0071] Further, as shown in FIG. 6, in the present embodiment, the uniform air module 23 includes a first uniform air passage portion 231, a second uniform air passage portion 232, and a porous plate 233. The first uniform air passage portion 231 directly communicates with the air blower 22 (as shown in FIG. 6) in the conveying direction d on the upstream side. The porous plate 233 has a plurality of fine holes 2331 penetrating therethrough to communicate the first uniform air passage portion 231 and the second uniform air passage portion 232. The second uniform air passage portion 232 communicates with the drying space F through the air outlet 234. In other words, the air blown by the air blower 22 first enters the cylindrical first uniform air passage portion 231, then flows downstream along the conveying direction d, the plurality of fine holes 2331 on the porous plate 233 cause the air flow in the first uniform air passage portion 231 to be fine and enter the second uniform air passage portion 232, and finally the air is blown from the air outlet 234 to the drying space F. In the present embodiment, the plurality of fine holes 2331 are arranged in parallel to the conveying direction d, but the present application is not limited thereto. The fine holes 2331 can also be arranged in a mesh shape. Figure 3 Figure 1 Figure 2 Figure 4 Further, as shown in FIG. 6, in the present embodiment, the first uniform air passage portion 231 is a quadrangular column having a first reflection surface 2311, a second reflection surface 2312, a third reflection surface 2313, and a fourth reflection surface 2314. After the air blown by the air blower 22 enters the first uniform air passage portion 231, the air collides with and is reflected back and forth among the above-mentioned reflection surfaces, thereby being differentiated to form a complex air flow traveling in a plurality of different vectors, with the purpose of homogenizing the originally strong air flow in a single direction. However, the present application is not limited thereto, and the first uniform air passage portion 231 can have other shapes, structures, or reflection surfaces arranged in different manners.

[0072] Further, as shown in FIG. 6, in the present embodiment, the first uniform air passage portion 231 is a quadrangular column having a first reflection surface 2311, a second reflection surface 2312, a third reflection surface 2313, and a fourth reflection surface 2314. After the air blown by the air blower 22 enters the first uniform air passage portion 231, the air collides with and is reflected back and forth among the above-mentioned reflection surfaces, thereby being differentiated to form a complex air flow traveling in a plurality of different vectors, with the purpose of homogenizing the originally strong air flow in a single direction. However, the present application is not limited thereto, and the first uniform air passage portion 231 can have other shapes, structures, or reflection surfaces arranged in different manners. Figure 3

[0073] Further, as shown in FIG. 6, in the present embodiment, the first uniform air passage portion 231 is a quadrangular column having a first reflection surface 2311, a second reflection surface 2312, a third reflection surface 2313, and a fourth reflection surface 2314. After the air blown by the air blower 22 enters the first uniform air passage portion 231, the air collides with and is reflected back and forth among the above-mentioned reflection surfaces, thereby being differentiated to form a complex air flow traveling in a plurality of different vectors, with the purpose of homogenizing the originally strong air flow in a single direction. However, the present application is not limited thereto, and the first uniform air passage portion 231 can have other shapes, structures, or reflection surfaces arranged in different manners. Figure 3 ​​​​​​As shown, in this embodiment, the second air distribution channel 232 is a polygonal prism with multiple reflective surfaces, and its cross-section tapers towards the drying space F. In this embodiment, the second air distribution channel 232 has reflective surfaces 2321, 2322, 2323, and 2324, which, together with two perforated plates 233, form a roughly hexagonal prism structure. Similarly, the airflow entering the second air distribution channel 232 from the fine holes 2331 is reflected and homogenized within the multiple reflective surfaces before entering the drying space F from the air outlet 234. However, the invention is not limited to this; the second air distribution channel 232 can have other shapes, structures, or reflective surfaces with different arrangement methods.

[0074] Furthermore, such as Figure 2 As shown, in this embodiment, at least one section of the return channel R has a cross-sectional area that gradually widens from narrow. In this embodiment, the cross-sectional area of ​​the second end R2 gradually widens along the airflow return direction. That is, the air pressure is highest at the second end R2, and the air pressure decreases further away from the second end R2 (negatively correlated with the cross-sectional area). This arrangement allows the airflow downstream of the drying space F to naturally flow into the return channel R through the pressure difference and be returned to the blower for reuse, saving heat energy loss.

[0075] However, the invention is not limited thereto. In another example, such as Figure 2 As shown, the second end R2 can also be equipped with an exhaust mechanism 4 to force the airflow downstream of the drying space F to the return channel R.

[0076] Furthermore, such as Figure 2 As shown, in this embodiment, the airflow blowing mechanism 2 includes two heaters 24, which are respectively disposed between the blower 22 and the air distribution module 23. The two heaters 24 can be selectively turned on, thereby controlling the changes in the drying process.

[0077] Furthermore, such as Figure 2 As shown, in this embodiment, the end of the separator 3 facing the conveying surface 11 is made of abrasion-resistant material. The separator 3 is, for example, a brush, with one end fixed to the housing 21 and the other end (facing the conveying surface 11) consisting of multiple densely arranged bristles. The densely arranged bristles effectively prevent airflow mixing on both sides of the separator 3, achieving excellent isolation. Simultaneously, the abrasion-resistant brush can flexibly contact the conveying surface 11 without damaging it. However, the invention is not limited to this; the separator 3 can be made of other materials or have other structures.

[0078] Furthermore, such as Figures 1 to 5As shown, in this embodiment, the conveying belt 1 is a circulating conveying belt. The end of the workpiece S with magnetism is attracted to the conveying surface 11 and is circulated. However, the present application is not limited thereto, and the conveying belt 1 can also be a non-circulating conveying belt or a conveying belt.

[0079] Further, in this embodiment, the conveying belt 1 is a vertical circulating conveying belt. That is, the central axis of the conveying belt 1 is parallel to the ground, and the workpiece S is attracted by magnetic force so as not to fall off the conveying surface 11. However, the present application is not limited thereto, and the conveying belt 1 can also be a horizontal circulating conveying belt, with the central axis perpendicular to the ground.

[0080] Further, as shown in FIG. 1, in this embodiment, the conveying belt 1 is provided with at least one separating member 3. The separating member 3 is preferably located in the drying space F and is preferably located in the middle of the conveying direction d. The separating member 3 is preferably a magnetic member, and the workpiece S is attracted to the separating member 3 by magnetic force. However, the present application is not limited thereto, and the separating member 3 can also be a non-magnetic member. Figure 4 and Figure 5 As shown, in this embodiment, the conveying belt 1 is provided with at least one separating member 3. The separating member 3 is preferably located in the drying space F and is preferably located in the middle of the conveying direction d. The separating member 3 is preferably a magnetic member, and the workpiece S is attracted to the separating member 3 by magnetic force. However, the present application is not limited thereto, and the separating member 3 can also be a non-magnetic member.

[0081] Further, as shown in FIG. 1, in this embodiment, the conveying belt 1 is provided with at least one separating member 3. The separating member 3 is preferably located in the drying space F and is preferably located in the middle of the conveying direction d. The separating member 3 is preferably a magnetic member, and the workpiece S is attracted to the separating member 3 by magnetic force. However, the present application is not limited thereto, and the separating member 3 can also be a non-magnetic member. Figure 6 Further, as shown in FIG. 1, in this embodiment, the conveying belt 1 is provided with at least one separating member 3. The separating member 3 is preferably located in the drying space F and is preferably located in the middle of the conveying direction d. The separating member 3 is preferably a magnetic member, and the workpiece S is attracted to the separating member 3 by magnetic force. However, the present application is not limited thereto, and the separating member 3 can also be a non-magnetic member.
