[0002] To prevent self-tapping screws from rusting and to ensure their appearance, a layer of paint is applied during the manufacturing process.

[0003] Existing spray baking devices for self-tapping screw processing simply use conventional conveyor belts for transport, which can easily lead to screw accumulation during transport. This results in uneven baking of the accumulated screws by the spray oven, affecting the efficiency and quality of the paint coating. To address the above problems, this utility model proposes a spray baking device for self-tapping screw processing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray baking device for processing self-tapping screws to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a spray oven for processing self-tapping screws, the structure of which includes a frame, and a material distribution and transmission component is horizontally arranged on the top surface of the frame, and a spray oven assembly is sleeved in the middle of the frame. Multiple baffles are horizontally arranged on the front and rear sides of the cavity of the spray oven assembly, and the upper end of each baffle assembly flexibly abuts against the upper end of the material distribution and transmission component. Multiple anti-detachment plates are fitted with gaps on the upper front and rear sides of the right end of the material distribution and transmission component, and a discharge hopper and a collection box are arranged below the left end of the material distribution and transmission component.

[0006] The material distribution and transmission assembly includes a first rotating shaft group and a second rotating shaft group. Two rotating belts mesh on the front and rear sides of the first rotating shaft group and the second rotating shaft group, and multiple clamping rod groups are longitudinally and equally spaced between the two rotating belts. A motor is driven to the front end of the first rotating shaft group.

[0007] A further improvement is that the spray oven assembly includes a spray oven, and a first baking lamp and a second baking lamp are provided at the upper and lower ends of the spray oven cavity. Multiple air extraction ports are provided on the front and rear sides of the spray oven, and the other end of each air extraction port is connected to an air filter through an air extraction pipe.

[0008] A further improvement is that each of the aforementioned lever groups includes a crossbeam, and multiple L-shaped levers are spaced apart on the top surface of the crossbeam, and each L-shaped lever has an inclined lever surface on its right side, and each L-shaped lever is made of rubber.

[0009] A further improvement is that the first rotating shaft group includes a longitudinal shaft, and two gear discs and two first bearings are embedded on the left and right sides of the longitudinal shaft body. The first rotating shaft group has the same structure as the second rotating shaft group.

[0010] A further improvement is that each of the rotating belts includes a belt body, and the inner side of the belt body has teeth arranged in a circular array to mesh with the toothed disc, and the front side of the belt body has multiple sleeve holes spaced at equal intervals.

[0011] A further improvement is that each of the aforementioned clamping rod assemblies includes a clamping rod, and the left and right sides of the clamping rod are provided with a fixing rod and a second bearing for embedding into the sleeve hole. The side of the clamping rod body flexibly abuts against the inclined dial surface.

[0012] A further improvement is that the first heating element, the second heating element, and the air filter are existing technologies, and their structures will not be described in detail here.

[0013] The beneficial effects of the utility model are:

[0014] This utility model provides a spray-baking device for processing self-tapping screws. It comprises a material distribution and transmission assembly consisting of a first rotating shaft group, a second rotating shaft group, two rotating belts, multiple clamping rod groups, and a motor, working in conjunction with multiple toggle plate groups at a spray oven assembly. This device automatically distributes and suspends the painted screws from the right end, preventing screw accumulation. When the suspended screws enter the spray oven assembly, the multiple toggle plate groups sequentially pull and rotate the clamping rod groups containing the screws, enhancing the movement of the suspended screws. This allows the first and second baking lamps on the spray oven assembly to evenly bake the screws from both top and bottom, improving baking efficiency and quality, and offering strong practicality.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-6 The present invention discloses a spray oven assembly for processing self-tapping screws. The assembly includes a frame 1, with a material distribution and transmission component 2 horizontally arranged on the top surface of the frame 1. A spray oven assembly 3 is fitted in the middle of the frame 1. Multiple paddle groups 4 are horizontally arranged on the front and rear sides of the cavity of the spray oven assembly 3. The upper ends of each paddle group 4 flexibly abut against the upper end of the material distribution and transmission component 2. Multiple anti-detachment plates 5 are fitted with gaps on the upper front and rear sides of the right end of the material distribution and transmission component 2. A discharge hopper 6 and a collection box 7 are arranged below the left end of the material distribution and transmission component 2. The material distribution and transmission component 2 includes a first rotating shaft assembly 21 and a second rotating shaft assembly 22. Two rotating belts 23 mesh on the front and rear sides of the first rotating shaft assembly 21 and the second rotating shaft assembly 22. Multiple clamping rods 24 are longitudinally and equidistantly spaced between the two rotating belts 23. A motor 25 is connected to the front end of the first rotating shaft assembly 21.

[0023] The spray oven assembly 3 includes a spray oven 31, and the upper and lower ends of the spray oven 31 are provided with a first baking lamp 32 and a second baking lamp 33. The spray oven 31 has multiple air extraction ports 34 on the front and rear sides, and the other end of each air extraction port 34 is connected to an air filter 35 through an air extraction pipe.

[0024] Each of the aforementioned lever groups 4 includes a crossbeam 41, and a plurality of L-shaped levers 42 are spaced apart on the top surface of the crossbeam 41, and each L-shaped lever 42 has an inclined lever surface 43 on its right side, and each L-shaped lever 42 is made of rubber.

[0025] The first rotating shaft assembly 21 includes a longitudinal shaft 211, and two gear discs 212 and two first bearings 213 are embedded on the left and right sides of the longitudinal shaft 211. The first rotating shaft assembly 21 has the same structure as the second rotating shaft assembly 22.

[0026] Each of the rotating belts 23 includes a belt body 231, and the inner side of the belt body 231 is provided with teeth 232 that mesh with the toothed disc 212 in a circular array at the center, and the front side of the belt body 231 is provided with a plurality of sleeve holes 233 at equal intervals.

[0027] Each of the clamping rod groups 24 includes a clamping rod 241, and the left and right sides of the clamping rod 241 are provided with a fixing sleeve rod 242 and a second bearing 243 for embedding into the sleeve hole 233. The side of the clamping rod 241 flexibly abuts against the inclined dial surface 43.

[0028] Working principle:

[0029] First, the motor 25 drives the first rotating shaft assembly 21 to rotate, thereby linking the two rotating belts 23 and each clamping rod assembly 24 to rotate and convey the screws to the left between the first rotating shaft assembly 21 and the second rotating shaft assembly 22. The painted screws enter from the right end and are fed onto the top surface of each clamping rod assembly 24. The gap between two adjacent clamping rods 241 allows the screws to be clamped vertically, achieving even distribution of the screws and preventing accumulation. The anti-detachment plate 5 prevents the screws from falling to the side during feeding. Furthermore, when the screws are clamped vertically... When the wire is conveyed to the left into the spray oven 31, the clamping rod 241 where the screw is located will flexibly abut against the inclined surfaces 43 on the front and rear two baffle groups 4, so that the clamping rod 241 where the screw is located will rotate, increasing the movement of the screw. This makes it easier for the first baking lamp 32 and the second baking lamp 33 to evenly bake the screw in the enhanced movement state from the top and bottom ends. When the screw after baking and spraying is conveyed to the lower left, the screw will automatically fall into the discharge hopper 6 in an inclined and upside-down state and flow into the collection box 7.

[0030] In addition, when the spray oven 31 is baking the screws for painting, the generated gas will be drawn into the air filter 35 through each air extraction port 34 for air filtration before being discharged outside.
