[0034] The adjusting component includes a support sleeve 31, which is used to support the roller 3. The support sleeve 31 is fixedly connected to the front surface of the roller 3. The support sleeve 31 passes through and is rotatably connected to the front surface of the U-shaped frame 1. A circular groove 36 is provided on the inner wall of the front end of the support sleeve 31. The ball 34 slides into the circular groove 36 to limit the rotating rod 32 so that the rotating rod 32 can rotate with the roller 3. The inner wall of the roller 3 is rotatably connected with the rotating rod 32. The rotating rod 32 can drive the arc plate 39 to rotate and at the same time make the connecting port 38 adjustable. The amount of discharge can be controlled by adjusting the alignment size of the connecting port 38 with the discharge port 41. The left side of the rotating rod 32 is fixedly connected with an arc plate 39 near the inner wall of the roller 3. The arc plate 39 is attached to the inner wall of the roller 3. A connecting port 38 is provided on the left side of the arc plate 39, and multiple groups of connecting ports 38 are provided. Multiple groups of connecting ports 38 correspond to multiple groups of discharge ports 41.
[0035] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 A limiting assembly is provided on the left side of the U-shaped frame 1, and the limiting assembly includes a limiting block 7, which can limit the buckle 6. The limiting block 7 is rotatably connected to the left side of the U-shaped frame 1 near the top of the storage shell 5. The left side of the storage shell 5 is fixedly connected with a buckle 6, and the buckle 6 cooperates with the limiting block 7 to limit the storage shell 5. The limiting block 7 is clamped on the inner wall of the buckle 6, and a circular ring 8 is fixedly connected to the left side of the U-shaped frame 1. The circular ring 8 supports the torsion spring 9. The limiting block 7 is elastically connected to the circular ring 8 through the torsion spring 9. The limiting torsion spring 9 is squeezed by rotating the limiting block 7 to release the limiting torsion spring 9. At the same time, the limiting block 7 is driven by the reverse force of the torsion spring 9 to reset the buckle 6 to limit the buckle 6.
[0036] Reference Figure 1 - Figure 4The left bottom of the discharge head 4 is provided with a discharge port 41 and multiple groups of discharge ports 41 are provided. The multiple groups of connecting ports 38 are connected with the multiple groups of discharge ports 41. When the connecting ports 38 and the discharge ports 41 are completely aligned, the discharge amount is the largest. When the connecting ports 38 are adjusted to move, the discharge amount can be slowly controlled. A positioning block 33 is fixedly connected to the front end of the support sleeve 31 on the left side of the rotating rod 32. The positioning block 33 is aligned with the connecting port 38. The position of the connecting port 38 can be judged by observing the position of the positioning block 33. A ball 34 is slidably connected to the right side of the rotating rod 32. The ball 34 is aligned with the rotating rod 3 The rotating rod 32 is elastically connected by the spring 35. When the rotating rod 32 is rotated, the ball 34 is driven to move and be squeezed by the support sleeve 31 and then squeeze the spring 35. When the ball 34 is aligned with the circular groove 36, the reverse force of the spring 35 is driven to reset and slide into the circular groove 36, thereby clamping the rotating rod 32. The ball 34 is clamped on the inner wall of the circular groove 36. The inner wall of the top of the drum 3 is fixedly connected with a fixing block 37 and two groups are provided. The two groups of fixing blocks 37 are symmetrically arranged with the center line of the rotating rod 32 as the symmetry axis. The two groups of fixing blocks 37 can limit the rotation distance of the arc plate 39.
[0037] Working principle: When in use, the rotating rod 32 is driven to rotate by rotating the positioning block 33, and the rotating rod 32 is driven to rotate the arc plate 39 and the connecting port 38 at the same time. When the connecting port 38 is aligned with the discharge port 41, the discharge amount is maximum at this time. When the arc plate 39 is rotated to move the connecting port 38, the discharge amount can be controlled after the connecting port 38 and the discharge port 41 are offset. At the same time, when the rotating rod 32 rotates, it drives the ball 34 to rotate and be squeezed by the support sleeve 31 so that the ball 34 squeezes the spring 35. After the position of the arc plate 39 and the connecting port 38 is controlled by controlling the discharge amount, the reverse force of the spring 35 is squeezed to drive the ball 34 to reset and slide into the circular groove 36 to limit the position, thereby limiting the rotating rod 32, thereby controlling the discharge amount, thereby improving the coating quality.
[0038] When the excess material is scraped into the material storage shell 5 during coating, the limit block 7 can be rotated to squeeze the torsion spring 9 to contact the limit of the buckle 6, and the material storage shell 5 can be moved by pulling the buckle 6. After the material storage shell 5 is removed, the excess material from coating can be recovered, which is relatively convenient. After the recovery is completed, the material storage shell 5 is put back into the U-shaped frame 1, and the reverse force of the torsion spring 9 that is squeezed drives the limit block 7 to reset the buckle 6 and thus limit the material storage shell 5. At this time, the coating process can be continued, which improves the convenience of operation.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
