Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine spray gun adjustment device. Background Technology

[0002] Seed coating machines are primarily used to coat seeds, forming a protective film on their outer surface. This protective film not only enhances seed stability, bioavailability, and aesthetics but also prevents pests and diseases and improves product taste and quality. Through the processing of seed coating machines, various materials can achieve the desired coating effects to meet diverse application needs.

[0003] When processing different amounts of material to be coated, longer roller coating machines can significantly improve the spraying effect and ensure uniform coating of the material surface by using an arc-shaped arrangement of the spray guns.

[0004] In actual use, when the amount of material to be coated changes and the curvature of the spray gun needs to be adjusted to adapt to the new spraying requirements, since the spray gun is usually fixed on a preset curvature, adjusting its position to adapt to different amounts of material often requires a complex mechanical adjustment or repositioning process, which increases the difficulty of adjustment.

[0005] Therefore, a coating machine spray gun adjustment device is needed to solve the above problems. Utility Model Content

[0028] Please see Figure 1-5 This utility model provides a technical solution: a coating machine spray gun adjustment device, including a support plate 1, an adjustment component 3, and an atomizing component. The adjustment component 3 is provided at the lower end of the support plate 1, and a spraying component 4 is installed at the lower end of the adjustment component 3. The adjustment component 3 includes two sets of adjustment blocks 31. Slide rails 11 are fixed on both sides of the lower end of the support plate 1. Two sets of slide grooves 311 are opened at the upper end of the adjustment blocks 31. The adjustment blocks 31 are movably installed at the lower end of the slide rails 11 through the slide grooves 311. An adjustment plate 32 is fixedly installed between the two sets of adjustment blocks 31. A drive component 34 is installed in the middle of the support plate 1. Two sets of lead screws 33 are connected to the lower end of the drive component 34. Two sets of lead screw nuts 312 are opened at the upper end of the adjustment plate 32. The lead screws 33 are installed in the lead screw nuts 312. The spraying component 4 includes multiple sets of atomizing spray guns 41. The atomizing spray guns 41 are installed on the side of the adjustment plate 32.

[0029] During use, the support plate 1 serves as the base of the entire adjustment device, the slide rail 11 provides a sliding track for the adjustment block 31, the adjustment block 31 can move on the slide rail 11 through the slide groove 311, the adjustment plate 32 is fixedly installed between the adjustment blocks 31, the movement of the adjustment block 31 will directly affect the curvature of the adjustment plate 32, the curvature of the adjustment plate 32 determines the arrangement curvature of the multiple sets of atomizing spray guns 41, the drive component 34 provides power to the lead screw 33, and the atomizing spray gun 41 is responsible for spraying the coating material evenly onto the material to be coated in the form of atomization.

[0030] A spray gun tube 42 is connected to the rear side of the atomizing spray gun 41, and a connecting pipe 43 is provided at the rear side of the atomizing spray gun 41. Multiple sets of atomizing spray guns 41 are connected to the connecting pipe 43 at the rear side through the spray gun tube 42. The spray gun tube 42 is a transmission channel responsible for conveying the coating material from a unified feed port to each atomizing spray gun 41. The connecting pipe 43 serves as a unified feed port.

[0031] A connecting joint 431 is fixed on the outside of the connecting pipe 43. The connecting joint 431 serves as a bridge between the connecting pipe 43 and the external feeding system or other related equipment.

[0032] A support frame 2 is fixed to the upper end of the support plate 1, and the connecting pipe 43 is fixedly installed at the lower rear end of the support frame 2. By using the support frame 2, it can be ensured that the connecting pipe 43 can maintain a stable position during operation.

The system includes a secondary bearing 346, a main bearing 344, and a secondary bearing 346, which are fixed together by a sleeve 347. One end of the sleeve 347 is wrapped around the main bearing 344 by an end cap 348. A motor 341 is fixed to a support plate 1. A worm gear 349 is installed between the worm wheels 343 of the two drive modules. The motor 341 drives the worm gear 349 to rotate, which in turn drives the worm wheels 343 to rotate. The worm wheels 343 then drive the bushing 342, the lead screw 33, and the limit sleeve 345 to rotate. The lead screw 33 drives the lead screw nut 312 and the adjusting plate 32 to move reciprocally. The drive modules are encased in and fixed to the support plate 1 by a mounting shell 35.

[0036] As an embodiment of this utility model: when using the coating machine spray gun adjustment device, when the amount of material to be coated changes, the drive component 34 is started first, which drives the lead screw 33 to rotate. The lead screw 33 will force the adjustment block 31 to be squeezed inward under the constraint of the slide rail 11, thereby causing the adjustment plate 32 to bend. The bending will directly affect the curvature of the multiple sets of atomizing spray guns 41 installed on the side of the adjustment plate 32, thus completing the curvature adjustment of the coating machine spray gun adjustment device.

[0037] It simplifies the process of adjusting the spray gun position, eliminating the need for complex mechanical adjustments or repositioning. It can quickly adapt to different amounts of coating material, improving the flexibility and efficiency of the coating process and reducing the difficulty of adjustment.
