Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1 - 5 , a drying device for screw processing includes two parallel cross beams 1, and support legs 2 are installed at the ends of the cross beams 1;

[0027] As Figure 1 shown, first rollers 3 are provided at both lower ends between the two cross beams 1. The ends of the first rollers 3 are rotatably connected to the support legs 2, and a first drive motor 6 is installed at one end of one of the first rollers 3. The first drive motor 6 is installed on the support leg 2. Second rollers 4 are provided at both ends between the two cross beams 1. The ends of the second rollers 4 are rotatably connected to the cross beams 1, and a conveyor belt 5 is installed on the second rollers 4 and the first rollers 3. A plurality of through holes arranged at intervals are formed in the conveyor belt 5. When the first drive motor 6 operates, the first roller 3 starts to drive the conveyor belt 5 to move, so as to convey the screws placed on the conveyor belt 5. The through holes in the conveyor belt 5 allow the accumulated water on the screws to pass through the conveyor belt 5 and fall downward;

[0028] Furthermore, in order to stably support the screws by the conveyor belt 5, a plurality of support rollers 18 arranged at intervals are provided between the two second rollers 4. The ends of the support rollers 18 are rotatably connected to the cross beams 1, and the sides of the support rollers 18 are in close contact with the inner side of the conveyor belt 5, which can improve the support strength at the top of the conveyor belt 5, so that the conveyor belt 5 will not sag due to the gravity of the screws, so as to make the conveyor belt 5 convey the screws more smoothly horizontally and prevent the screws from gathering too much due to the depression of the conveyor belt 5.

[0029] It should be noted that as Figure 1 and Figure 2As shown in the figure, a collection trough 19 is provided below between two cross beams 1. The collection trough 19 corresponds to the conveyor belt 5 located between the two cross beams 1, and the collection trough 19 is fixed to the support legs 2 through brackets. A drain pipe 20 is installed at the bottom of the collection trough 19. When the accumulated water on the screws passes through the conveyor belt 5 above, the accumulated water will centrally fall into the collection trough 19 and be discharged centrally and uniformly by the drain pipe 20.

[0030] When the screws are continuously conveyed through the conveyor belt 5, at least one cross-flow fan 8 is provided above the conveyor belt 5. The cross-flow fan 8 is installed on a U-shaped frame 7 with an opening downward. The end of the U-shaped frame 7 is fixed to the cross beam 1. A heating component 16 is provided below the cross-flow fan 8. The heating component 16 is fixed to the frame 17, and the frame 17 is fixed to the U-shaped frame 7. In the actual use process, the heating component 16 is one of an electric heating wire, a heating rod, and a heating plate, so as to heat the air below the cross-flow fan 8, and then the hot air is blown by the cross-flow fan 8 and sent to the conveyor belt 5, thereby heating and drying the screws passing below the cross-flow fan 8.

[0031] In addition, as the screws are continuously conveyed on the conveyor belt 5, at least two drive shafts 11 are provided inside the U-shaped frame 7. The ends of the drive shafts 11 are rotatably connected to the side surfaces of the U-shaped frame 7, and adjacent drive shafts 11 are connected by a transmission mechanism 15. The transmission mechanism 15 is one of a chain drive and a belt drive, so that adjacent drive shafts 11 can rotate relative to each other. A second drive motor 14 is installed at the end of one of the drive shafts 11. The second drive motor 14 is installed on the U-shaped frame 7 to provide power for the rotation of the drive shaft 11.

[0032] A plurality of turnover plates 12 arranged at intervals are provided on the side surface of each drive shaft 11. The turnover plates 12 are arranged along the axis direction of the drive shaft 11 and are in clearance fit with the conveyor belt 5. The turnover plates 12 are connected to the drive shaft 11 through a plurality of connecting rods 13 arranged at intervals, so that the turnover plates 12 rotate with the drive shaft 11, thereby turning the screws on the conveyor belt 5, so as to enable the screws to better contact with the hot air, thereby improving the drying efficiency of the screws.

[0033] Specifically, as Figure 5 shown, the directions between the turnover plates 12 on adjacent drive shafts 11 are opposite, that is, the turnover plates 12 can shovel up the screws and let the screws slide along the top surface of the turnover plates 12 and then fall back onto the conveyor belt 5, so as to prevent the screws from gathering and causing the situation that the screws do not fully contact with the hot air.

[0034] Furthermore, as Figure 1 and Figure 3As shown in the figure, limiting plates 9 are provided on both sides above the conveyor belt 5. The limiting plates 9 are fixed to the U-shaped frame 7 through the connecting frame 10, and the bottom of the limiting plate 9 is in clearance fit with the top surface of the conveyor belt 5, which can block both sides of the conveyor belt 5 to prevent screws from falling from the side of the conveyor belt 5 when the turning plate 12 turns the screws.

[0035] It should be further noted that the frames 17 are arranged around the outside of the cross-flow fan 8 to make the air blown by the cross-flow fan 8 flow downward in a concentrated manner, and a metal mesh is installed at the bottom of the frames 17 to protect the cross-flow fan 8 and the heating component 16, preventing the shoveled screws from contacting them and causing damage.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
