[0002] A dryer is a metal workpiece drying box that heats the objects to evaporate the moisture in them, thereby achieving the purpose of drying the objects. Different product fields require different dryers, and after washing the electroplated metal parts, a dryer is needed to remove water and dry them to ensure that the drying of the metal parts does not affect the subsequent processing flow.

[0003] Most of the existing metal drying ovens on the market place metal parts in the drying oven to dry their outer walls with the help of hot air. However, when drying metal parts with annular outer walls, due to the special shape of the annular metal parts, the hot air may not be able to blow evenly to all parts of the parts, resulting in uneven drying. Therefore, it is necessary to redesign a hot air convection drying oven to address the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A hot air convection drying box includes a box body 1, both ends of the box body 1 are open, and the inner walls of both sides of the box body 1 are symmetrically provided with blowing plates 11, and the blowing plates 11 are tilted. The inner wall of the box body 1 is rotatably connected to two sets of transmission rollers 7, and the two sets of transmission rollers 7 are connected by a transmission belt 6. The inner wall of the box body 1 is rotatably connected to a reciprocating screw 8, and the reciprocating screw 8 is connected to a device block 12 through a connecting mechanism. The lower end surface of the device block 12 is provided with a device groove 13, and the top of the device groove 13 is fixedly connected to a spring 15, and the spring 15 is connected to a connecting rod 16 through a sliding mechanism. The connecting rod 1 6 is fixedly connected with a slide plate 17 at the end thereof, the connecting mechanism comprises a screw sleeve 10 threadedly connected to the threaded section of the reciprocating screw 8, a device block 12 is fixedly connected to the lower end surface of the screw sleeve 10, a sliding mechanism comprises a slider 14 slidably connected in the device groove 13, the other end of a spring 15 is fixedly connected to the slider 14, an end of a connecting rod 16 is fixedly connected to the lower end surface of the slider 14, and an inclination angle formed by the slide plate 17 and the inner wall of the box body 1 is forty-five degrees, so as to better contact with the parts, make the parts rotate in a larger range, and better contact with the convective hot air.

[0022] refer to Figure 1 , Figure 2 The outer wall of the box body 1 is rotatably connected with the first transmission wheel 3 and the second transmission wheel 4. The first transmission wheel 3 is coaxially fixedly connected to the reciprocating screw 8. The second transmission wheel 4 is coaxially fixedly connected to its adjacent transmission roller 7. The first transmission wheel 3 is connected to the second transmission wheel 4 through a belt 5. The rotation of the reciprocating screw 8 can be synchronously realized with the help of the transmission roller 7, and there is no need to provide a separate power output source for the reciprocating screw 8, thereby reducing the loss of the overall device during use.

[0023] refer to Figure 2 The inner wall of the box body 1 is fixedly connected with a limit rod 9, the limit rod 9 is slidably connected with the screw sleeve 10, and the lower end surface of the slide plate 17 is fixedly connected with a rubber pad 18, which can increase the friction between the parts.

[0024] refer to Figure 3 The inner wall of the device groove 13 and the outer wall of the slider 14 are both square, the outer wall of the slider 14 contacts the inner wall of the device groove 13, the outer wall of the box body 1 is fixedly connected to the servo motor 2, and the output shaft of the servo motor 2 is fixedly connected to the adjacent transmission roller 7; it should be noted that the elastic resistance of the spring 15 is less than the rotation speed of the transmission roller 7, and then when the transmission belt 6 drives the parts to slide, the parts only briefly contact the slide plate 17, compress the spring 15, and then slide out from the back of the slide plate 17.

[0025] In the utility model, when the device is used, the servo motor 2 and the blowing plate 11 are started, connected with the external fan, and hot air is blown into the box body 1, and the hot air blown by the symmetrically arranged blowing plate 11 forms a convection hot air flow, so as to better cover the surface of the metal parts.

Then the metal parts are placed on the upper end of the transmission belt 6, and the blown heat can dry the outer surface of the metal parts. At the same time, during the rotation of the transmission roller 7, the second transmission wheel 4 is synchronously driven to rotate, and with the help of the provided belt 5, the self-rotation of the reciprocating screw 8 can be realized, and the screw sleeve 10 on the screw and the threaded section drives the lower component to slide horizontally. When the metal parts slide to the bottom of the slide plate 17, the rubber pad 18 at the lower end of the slide plate 17 contacts the outer wall of the metal parts, and then drives it to rotate, and cooperates with the blowing plate 11 to blow out convection hot air, which can fully dry the metal parts and ensure the uniformity during drying.

[0026] The spring 15 provided at the same time can ensure that after the slide plate 17 contacts the part, it cooperates with the transmission belt 6 to drive the part to slide. When the part itself contacts the slide plate 17, its movement state is in a state of rotation. The elastic performance of the provided spring 15 is relatively weak. After a short contact time, it drives the slider 14 to slide upward and compresses the spring 15 at the same time. In this way, it can ensure that the part slides out from the other end of the box body 1 and realizes the flipping of the part at the same time.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
