Technical Field

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

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. The nozzle of the coating machine is a component of the equipment used to uniformly coat liquid coatings on the surface of paper or other substrates. The main function of the nozzle is to spray the coating evenly on the substrate surface in the form of a mist, so as to ensure the uniformity and quality of the coating.

[0003] During the use of coating machine nozzles, coating material often remains around the nozzle, which can easily clog the nozzle over time. Users need to clean the bottom of the nozzle regularly. Cleaning usually requires wiping the bottom of the nozzle one by one with a wiping cloth. If the coating material dries and clumps, the wiping cloth needs to be soaked in clean water, wrung out, and then wiped. The process is cumbersome. Therefore, a coating machine nozzle is proposed to address the above problems. Utility Model Content

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] A coating machine nozzle includes a nozzle body 1 and a nozzle head 2 for spraying coating material. A plurality of nozzle heads 2 are connected to the bottom of the nozzle body 1. A cleaning assembly 3 is located below each nozzle head 2. The cleaning assembly 3 includes a moving strip 31, a scraper 32, Velcro 33, and a wiping cloth 34. The moving strip 31 is located below each nozzle head 2, and the scraper 32 is fixedly connected to the top of the moving strip 31. The wiping cloth 34 is tightly fitted to the outer side of the scraper 32. A moving assembly 5 is located on one side of the scraper 32. The moving assembly 5 includes a fixing block 51, a limiting plate 52, a sliding rod 53, a slider 54, and a telescopic rod. 55 and fixed plate 56, fixed blocks 51 are fixedly connected to both sides of the nozzle body 1, a limit plate 52 is fixedly connected to the bottom of the fixed block 51, a sliding rod 53 is fixedly connected to one side of the limit plate 52, a slider 54 is slidably connected to the outside of the sliding rod 53, a telescopic rod 55 is fixedly connected to the bottom of the slider 54, and a fixed plate 56 is fixedly connected to the bottom of the telescopic rod 55. The cleaning component 3 and the moving component 5 are used together to facilitate quick and convenient cleaning of residual spray material at the bottom and around the bottom of the nozzle 2. The spray bottle 4 facilitates wetting of the wiping cloth 34.

[0022] The inner side of the wiping cloth 34 and the outer side of the moving strip 31 are both fitted with Velcro 33. The top of the scraper 32 is arc-shaped and the whole is elastic, so that the wiping cloth 34 will not damage the bottom of the spray head 2 when wiping it. One of the fixing blocks 51 is fixedly connected to a support block 8 on one side. The spray bottle 4 is tightly fitted inside the support block 8, which makes it easy to pick up and put down the spray bottle 4. The bottom of the moving strip 31 is fixedly connected to a handle 6. The two ends of the moving strip 31 are fixedly connected to two fixing plates 56, which makes it easy to control the movement of the moving strip 31. The telescopic rod 55 is provided with a hand-tightening bolt 7 on one side. The surface of the telescopic rod 55 has a threaded hole, which makes it easy to fix the telescopic rod 55 for extension and retraction.

[0023] Workflow: When using the coating machine nozzle, first install the nozzle body 1 in a suitable position on the coating machine. The spray material is sprayed from the nozzle 2. After prolonged use, the spray material adheres to the bottom and sides of the nozzle 2. At this time, the user holds the handle 6 and moves the moving bar 31 to one side. The moving bar 31 moves the scraper 32 and the wiping cloth 34 in the same direction. Since the two ends of the moving bar 31 are fixedly connected to the fixed plate 56, the fixed plate 56 is fixedly connected to the telescopic rod 55, and the telescopic rod 55 is fixedly connected to the slider 54, the slider 54 slides on the outside of the sliding rod 53. When the wiping cloth 34 on the outside of the scraper 32 moves to the bottom of the nozzle 2, the scraper 32 is set with an elastic arc shape to avoid scratching or abrasions to the nozzle 2. The wiping cloth 34 is in close contact with the nozzle 2 to wipe and clean the residual spray material on its bottom and sides. When the spray material dries and clumps and remains on the bottom of the nozzle 2, the user removes the spray bottle 4 from the support block 8 and sprays and wets the wiping cloth 34. The cleaning component 3 is used to clean the dried and clumped spray material. After cleaning, the cleaning component 3 can be stored. The user holds the hand-tightening bolt 7 and turns it to one side until it is removed. Then, the user controls the telescopic rod 55 to be in the retracted state. The user holds the hand-tightening bolt 7 and aligns it with another threaded hole of the telescopic rod 55 and inserts and tightens it to fix the retracted telescopic rod 55. At this time, the height of the cleaning component 3 is higher than the height of the nozzle 2, which will not affect the normal use of the nozzle 2. When the wiping cloth 34 needs to be cleaned or replaced after long-term use, the wiping cloth 34 is directly torn off from the outside of the moving strip 31. Then, the Velcro 33 on the inside of the cleaned wiping cloth 34 or the new wiping cloth 34 is aligned with the Velcro 33 on the outside of the moving strip 31 and glued on. This completes the removal and installation of the wiping cloth 34. The cleaning component 3 and the moving component 5 work together to facilitate quick and convenient cleaning of residual spray material at the bottom and around the bottom of the nozzle 2. The spray bottle 4 facilitates wetting of the wiping cloth 34.
