[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0031] Example 1

[0032] Reference Figure 1-Figure 5 , a spraying device includes a conveyor belt 1, a spray box 2 is fixed on one side of the top of the conveyor belt 1, a first cover plate 4 is slidably connected to the top of the spray box 2, and a spraying mechanism is installed at the bottom of the first cover plate 4, and the spraying mechanism includes a first paint box 6, a circulation tube 7 and a blocking head 8. The first paint box 6 is fixed to the inner side of the bottom end of the first cover plate 4, and the two ends of the first paint box 6 are evenly fixed with circulation tubes 7, so that the paint inside the first paint box 6 can flow out to the outside through the circulation tube 7, and the outer side of the circulation tube 7 is threadedly connected to the blocking head 8, and a sealing ring can be added between the blocking head 8 and the circulation tube 7 as needed, so that when the first paint box 6 is used alone, the circulation tube 7 can be sealed and closed by the blocking head 8;

[0033] The two ends of the first paint box 6 are slidably connected to the outside of the circulation tube 7 with the second paint box 9, so that labels of different widths can be sprayed by adding the second paint boxes 9 of different widths. The bottoms of the first paint box 6 and the second paint box 9 are fixed with nozzles. Both ends of the top of the first paint box 6 are equipped with positioning mechanisms for connecting the second paint box 9. The positioning mechanisms include a connecting plate 10, a positioning block 11 and a compression spring 12. Both ends of the top of the conveyor belt 1 are rotatably connected to the connecting plate 10. The interior of one end of the connecting plate 10 is slidably connected to the positioning block 11. The positioning mechanism The cross section of the block 11 is E-shaped. The positioning block 11 is slidably connected to the first paint box 6 and the second paint box 9, so that the first paint box 6 and the second paint box 9 can be unassembled. The positioning block 11 is positioned by the sliding connection with the first paint box 6. When the first paint box 6 and the second paint box 9 are assembled, the positioning block 11 is slidably connected to the second paint box 9 to complete the positioning of the first paint box 6 and the second paint box 9. A compression spring 12 is fixed at one end of the positioning block 11 and located inside the connecting plate 10, so that the movement of the positioning block 11 drives the compression spring 12 to stretch;

[0034] In this embodiment, L-shaped limiting grooves for connecting to the positioning blocks 11 are formed inside the top ends of the first paint box 6 and the second paint box 9 .

[0035] A water pump 5 is fixed at one end of the conveyor belt 1 and at a position corresponding to the spray box 2. The input end of the water pump 5 is connected to the external paint bucket through a hose, and the output end of the water pump 5 is connected to the first paint box 6 through a hose passing through the first cover plate 4, so that the water pump 5 can transport the external paint into the interior of the water pump 5. At the same time, the hose at the output end of the water pump 5 makes it easy to lift the first cover plate 4 and detach it from the slidingly connected spray box 2, thereby facilitating the assembly of the second paint box 9 at both ends of the first paint box 6.

[0036] In this embodiment, the height between the bottom nozzle of the first paint box 6 and the conveyor belt 1 is less than or equal to the height of the rectangular groove left at the bottom of the spray box 2, so that the gap between the bottom nozzle of the first paint box 6 and the label can be shortened, reducing the dispersion of paint caused by excessive distance;

[0037] In other embodiments, when the bottom of the first paint box 6 is a seal, the color of the seal is ensured by the paint, and an electric push rod is set between the first cover 4 and the first paint box 6, and the first paint box 6 is driven to rise and fall by the operation of the electric push rod.

[0038] The use process of the spraying device provided by the present invention is as follows: when in use, depending on the width of the label, when the width of the label is smaller than the width of the first paint box 6, the water pump 5 is directly operated to allow the water pump 5 to transport the external paint into the inner side of the first paint box 6 through the hose at the output end, and then spray it out through the nozzle at the bottom of the first paint box 6, thereby spraying the label;

[0039] When the width of the label is greater than the width of the first paint box 6, the sealing heads 8 at both ends of the first paint box 6 are rotated to disengage the threaded circulation tube 7, and then the first paint box 6 and the second paint box 9 are assembled by sliding the circulation tube 7, and then the connecting plate 10 is rotated so that the connecting plate 10 is rotated to the top groove of the second paint box 9 through the rotation connection with the first paint box 6. At this time, the positioning block 11 is pulled to allow the positioning block 11 to drive the compression spring 12 to stretch, and then the positioning block 11 is allowed to enter the second paint box 9 with sliding connection, so that the rebound of the compression spring 12 after stretching drives the positioning block 11 to reset, thereby fixing the first paint box 6 and the second paint box 9.

[0040] Example 2

[0041] Reference Figure 1 、 Figure 6 and Figure 7 , a spraying device, a drying box 3 is fixed on the other side of the top of the conveyor belt 1, a heating wire 13 is fixed at the bottom end of the inner side of the drying box 3, and a fan 14 is provided inside the drying box 3 and on the top of the heating wire 13, so that the wind heated by the outside of the heating wire 13 is blown downward by the operation of the fan 14, thereby heating the label sprayed on the top of the conveyor belt 1, and a filter 15 is slidably connected to the inside of the top of the drying box 3, so that the filter 15 can be directly assembled on the top of the drying box 3 by sliding, so that when the first cover plate 4 is working, the external air is filtered inside the filter 15 and then flows;

[0042] A limiting mechanism is installed on the top of both ends of the drying box 3, and the limiting mechanism includes a positioning frame 16, a pressure plate 17, a threaded column 18 and a limiting plate 19. The top of both ends of the drying box 3 is fixed with a positioning frame 16, and the inner side of the positioning frame 16 is slidably connected to the pressure plate 17, and the shape of the pressure plate 17 is L-shaped, so that the position of the filter 15 on the top of the drying box 3 is fixed by the descending of the pressure plate 17, and the inner side of the positioning frame 16 is slidably connected to the limiting plate 19, and the limiting plate 19 is slidably connected to the pressure plate 17, so that when the limiting plate 19 is located inside the pressure plate 17, the lifting and lowering of the pressure plate 17 inside the positioning frame 16 is limited. The end of the positioning frame 16 away from the drying box 3 is threadedly connected to the threaded column 18, and the threaded column 18 is rotatably connected to the limiting plate 19, and the movement of the threaded column 18 drives the limiting plate 19 to move horizontally.

[0043] The use process of the spraying device provided by the present invention is as follows: after the label is sprayed through the bottom of the spray box 2, the heating wire 13 is allowed to work, and at the same time, the fan 14 is allowed to work to draw external air through the filter 15, so that the air is heated on the outside of the heating wire 13 and the sprayed label is heated by air. At the same time, when the filter 15 is blocked, the threaded column 18 is rotated to drive the rotatably connected limit plate 19 to slide on the inside of the positioning frame 16. After the limit plate 19 is disengaged from the slidingly connected pressure plate 17, the pressure plate 17 is pulled upward, so that the filter 15 can be disengaged by rising through the sliding connection with the drying box 3, and then the filter 15 is cleaned and reinstalled.
