[0047] The following is for reference. Figures 1-6 The present invention describes an adjustment mechanism 10 for a hot-melt road marking machine 1. The adjustment mechanism 10 is disposed inside the body 20 of the hot-melt road marking machine 1. The adjustment mechanism 10 includes: an overflow main plate 100; a fixing plate 200, which is fixedly disposed at the top of the overflow main plate 100 along the height direction of the body 20 and connected to a paint partition (not shown in the figure) on the body 20; and an overflow plate 300, which is fixedly disposed at the bottom of the overflow main plate 100 along the height direction of the body 20 and arranged opposite to the paint outlet 22 of the hot-melt road marking machine 1. The overflow plate 300 is used to adjust the paint pressure (or discharge rate) at the paint outlet 22.

[0048] Specifically, the body 20 of the hot-melt road marking machine 1 may have a receiving cavity 21 inside, and the adjusting mechanism 10 may be disposed within the receiving cavity 21 of the body 20. Along the height direction of the body 20 of the hot-melt road marking machine 1, the upper side of the receiving cavity 21 may be connected to a feeding mechanism (not shown in the figure), and the lower side of the receiving cavity 21 may be opposite to a cutter head assembly (not shown in the figure). The height direction of the body 20 of the hot-melt road marking machine 1 can be... Figure 5 The direction indicated by X in the middle.

[0049] The overflow main plate 100 can be configured as an L-shaped structure with an opening angle greater than 90°, so that the paint is more uniform when flowing from the feeding mechanism to the paint outlet. The overflow main plate 100 can cooperate with the feeding mechanism to divide the paint channel into a paint forward flow channel 23 and a paint backflow channel 24. When the paint is transported from the feeding mechanism to the containing cavity 21, the paint can flow to the paint outlet 22 along the paint forward flow channel 23 formed by the cooperation of the machine body 20 and the overflow main plate 100, thereby improving the stability of the hot melt road marking machine 1.

[0050] The fixed plate 200 can be configured as a rectangular structure, and the number of fixed plates 200 can be two. One end of the fixed plate 200 can be fixedly connected to the top of the overflow main plate 100 along the height direction of the machine body 20, and the connection mode can be screw connection, welding or the like. The other end of the fixed plate 200 can be connected to the paint partition plate on the machine body 20 by welding, screw connection or the like. In this way, the cooperation of the fixed plate 200, the paint partition plate and the overflow main plate 100 can form the paint forward flow channel 23 and the paint backflow channel 24, thereby improving the utilization rate of the paint.

[0051] One end of the overflow plate 300 can be connected to the bottom of the overflow main plate 100 through the fixing piece 500, and the number of overflow plates 300 can be multiple. The present application does not make specific limitation on this, and the user can select different numbers of overflow plates 300 according to different application scenarios. The overflow plate 300 can be arranged opposite to the paint outlet 22 of the hot melt road marking machine 1, so that the overflow plate 300 can adjust the amount of paint at the position of the paint outlet 22, thereby making the amount of paint at the paint outlet 22 more uniform, and further ensuring the thickness of the marking line.

[0052] Specifically, when the feeding mechanism sends the paint to the paint forward flow channel 23, the paint can flow to the paint outlet 22 along the direction of gravity. When the paint pressure in the paint forward flow channel 23 is too large, the paint can flow into the paint backflow channel 24 from the gap between the overflow plate 300 and the knife head assembly, thereby adjusting the paint pressure in the paint forward flow channel 23, ensuring the stability of the amount of paint at the paint outlet 22, further ensuring the flow rate and thickness of the paint, and improving the stability and practicality of the hot melt road marking machine 1. The flow direction of the paint in the paint forward flow channel 23 can be the direction indicated by the arrow Z. Figure 6

[0053] ​According to the adjusting mechanism 10 for the hot melt road marking machine 1, the paint channel can be divided into the paint forward flow channel 23 and the paint backflow channel 24 by cooperating with the feeding mechanism. When the paint is conveyed from the feeding mechanism to the containing cavity 21, the paint can flow to the paint outlet 22 along the paint forward flow channel 23 formed by the cooperation of the machine body 20 and the overflow main plate 100, so that the stability of the hot melt road marking machine 1 can be improved. The paint forward flow channel 23 and the paint backflow channel 24 can be formed by the cooperation of the fixed plate 200, the paint partition plate and the overflow main plate 100, so that the utilization rate of the paint can be improved. The overflow plate 300 can be arranged opposite to the paint outlet 22 of the hot melt road marking machine 1, so that the overflow plate 300 can adjust the amount of paint at the position of the paint outlet 22, so that the amount of paint at the paint outlet 22 can be more uniform, and the thickness of the marking line can be ensured.
