[0002] Solvent-free coatings have become an important choice for industrial corrosion protection due to their environmentally friendly, efficient, and durable characteristics. However, due to the high precision required for lead screws, a corrosion-resistant coating needs to be evenly applied to the outer side of the lead screw.
[0003] A search revealed an existing patent (application number: CN202211729296.1) disclosing an automatic workpiece brushing machine. This invention includes a base, a fixed plate, a fixed block, a slide groove, a first motor, a first lead screw, a sliding plate, a connecting plate, a moving plate, a through groove, a second motor, a sliding rod, a second lead screw, a second moving block, an electric cylinder, a piston rod, a horizontal plate, a material box, a buffer box, a material pump, a material conveying pipe, an L-shaped fixed block, a brush mounting base, and an L-shaped cavity. The brush mounting base has a material distribution chamber inside, and the bottom cavity of the buffer box connects to the L-shaped cavity. The L-shaped cavity is connected to the material distribution chamber at one end, away from the internal cavity of the buffer box. Several diversion holes are formed on the right outer surface of the brush mounting base, and the internal cavities of these holes are connected to the material distribution chamber. A brush is mounted on the outer surface of the brush mounting base near the diversion holes. This structure solves the problem of applying adhesive to the outer annular plane of workpieces of different sizes, improving the brushing efficiency for workpieces of various sizes. This invention has a high degree of automation, improves production efficiency, saves labor and costs, and has good market application value. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:
[0004] Existing automatic workpiece coating machines cannot uniformly coat high-precision parts such as lead screws. Due to the large gaps between the threads on the outside of the lead screw, it is difficult to evenly apply the coating to the threads. In addition, the coating of the lead screw needs to be as thin as possible. If the coating is too thick, it will affect the accuracy of the lead screw.
[0005] Therefore, an environmentally friendly solvent-free lead screw coating processing device is proposed to address the above problems. Utility Model Content

[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. Compared with existing technologies, this environmentally friendly solvent-free lead screw coating processing device can spray and wipe the surface of the lead screw, and can drive the lead screw to rotate during the spraying and wiping process to carry out coating processing, making the coating of the lead screw more uniform. During the movement of the lead screw, the coating material in the solvent-free paint tank is sprayed evenly onto the surface of the lead screw through the spray nozzle via the connecting pipe. Excess coating material falls into the spray recovery box for recycling. After the lead screw is sprayed, when the lead screw passes through the wiping collar, the wiping sponge spreads the coating material evenly on the lead screw and absorbs the excess material.

During the rotation of the rotary gear, the transmission gear ring and the rotary sleeve connected to it are driven to rotate through the gear groove. During the rotation, the lead screw is rotated for spraying and wiping, thereby making the coating of the lead screw more uniform. Attached Figure Description

Furthermore, after the lead screw is sprayed, when the lead screw passes through the wiping collar 121, the wiping sponge 1212 spreads the coating material on the lead screw evenly and absorbs the excess coating material. The elastic deformation of the elastic silicone collar 1211 allows the wiping sponge 1212 to better contact the gaps in the threads on the lead screw.
[0030] In a preferred embodiment, a solvent-free paint tank 3 is connected to one side of the lead screw spray box 1. A replenishment port 31 is provided on the top of the solvent-free paint tank 3.

[0032] In a preferred embodiment, a rotary motor 53 is connected to the top of the lead screw transmission sleeve 5, and a rotary gear 531 is connected to one side of the rotary motor 53.

[0034] The working process of this utility model is as follows: The lead screw that needs to be coated can be inserted into the lead screw conveying sleeve 5 in the lead screw spraying box 1 through the lead screw inlet 11 or the lead screw outlet 12. The lead screw is connected to the rotating sleeve 51 of the lead screw conveying sleeve 5.
