A handle 4 is provided at the upper end of the armrest 3. A hot melt tank 5 and a control box 6 are provided on the base 1. A feeding structure 7 is provided on the hot melt tank 5. A spraying hopper 8 is installed on the base 1, and an opening and closing component 9 connected to the control box 6 is provided on the spraying hopper 8. Wheels 10 are provided on the lower surface of the base 1. A flip cover 11 is provided at the upper end of the hot melt tank 5 through a hinge, and a handle 12 is fixed on the flip cover 11. A transmission component is connected between the engine 2 and the wheels 10. The transmission component includes a sprocket and a chain. Two sprockets with different diameters are respectively installed on the rotating shafts of the engine 2 and the wheels 10, and the chain is sleeved on the two sprockets.

[0020] When using the device for hot melt marking, the device is placed on the road through the wheels 10 on the base 1. The staff holds the handle 4 at the upper end of the armrest 3 with both hands. After starting the engine 2, the engine 2 drives the wheels 10 to slowly rotate through the sprocket and chain in the transmission component, and the device starts to move slowly. At the same time, the control box 6 is started. After the materials inside the hot melt tank 5 are melted, they flow out through the feeding structure 7 and fall into the spraying hopper 8, and finally flow out from the spraying hopper 8 and fall to the ground, thereby achieving the purpose of hot melt marking. In this process, the flow rate of the materials flowing out can be adjusted through the feeding structure 7 to improve the flexibility of use. When needed, the spraying hopper 8 can be urgently closed by using the opening and closing component 9, further ensuring the flexibility and adaptability of use, and the use effect is excellent. When adding materials, the flip cover 11 is opened through the handle 12, materials are added into the hot melt tank 5 and then the flip cover 11 is closed again, and then the spraying marking can be continued.

[0021] Through the above implementation solutions, the blanking structure 7 includes a fixed frame 701, a blanking hopper 702, a lifting plate 703, a fixed rod 704, a top plate 705, a movable rod 706, a micro servo motor 707, a lead screw 708, a follower plate 709, and a lifting seat 710. The fixed frame 701 is fixedly connected to the blanking hopper 702, and the fixed frame 701 is installed on the hot-melting box 5. The lifting plate 703 is installed on the fixed frame 701. The fixed rod 704 is fixedly connected to the top plate 705, and the fixed rod 704 is installed on the base 1. The movable rod 706 is sleeved on the fixed rod 704. The micro servo motor 707 is installed on the top plate 705. The lead screw 708 is connected to the micro servo motor 707. The follower plate 709 is fixed on the lifting plate 703, and the follower plate 709 is fixedly connected to the movable rod 706. The lifting seat 710 is arranged on the movable rod 706, and the lifting seat 710 is threadedly connected to the lead screw 708. Through the arranged blanking structure 7, the micro servo motor 707 drives the lead screw 708 to rotate, and the lead screw 708 cooperates with the lifting seat 710, the movable rod 706, and the follower plate 709 to control the height of the lifting plate 703. It can not only quickly adjust the height of the lifting plate 703, but also ensure the adjustment accuracy and avoid excessive adjustment. At the same time, there is a self-locking effect between the lead screw 708 and the lifting seat 710, which can ensure that the lifting plate 703 is fixed after adjustment and guarantee the use stability after adjustment.

[0022] When using the blanking structure 7, during the process of adjusting the blanking rate, after starting the micro servo motor 707 on the top plate 705, the micro servo motor 707 drives the lead screw 708 to rotate, so as to drive the movable rod 706 to move along the fixed rod 704 through the lifting seat 710. During this process, the movable rod 706 drives the lifting plate 703 to move on the fixed frame 701 through the follower plate 709, thereby changing the distance between the lower end of the lifting plate 703 and the blanking hopper 702, and further changing the flow rate of the material. And due to the self-locking effect of the lifting seat 710 and the lead screw 708 after adjustment, the use stability of the lifting plate 703 can be guaranteed.

[0023] Through the above implementation solutions, the opening and closing assembly 9 includes an opening and closing plate 901, a connecting rod 902, a guiding rod 903, a limiting block 904, a supporting plate 905, a cross bar 906 and a footrest 907. The opening and closing plate 901 is fixedly connected to the connecting rod 902, and the opening and closing plate 901 penetrates through the side wall of the spraying hopper 8. The guiding rod 903 is connected to the connecting rod 902, and the end of the guiding rod 903 penetrates through the side wall of the spraying hopper 8. The limiting block 904 is arranged at the end of the guiding rod 903. The supporting plate 905 is installed on the control box 6. The cross bar 906 is fixedly connected to the footrest 907, and the end of the cross bar 906 is connected to the connecting rod 902. The cross bar 906 penetrates through the supporting plate 905. By using the opening and closing assembly 9, a footrest 907 is arranged at the end of the cross bar 906, which can be driven by the sole of the foot, facilitating the quick movement of the opening and closing plate 901 and improving the flexibility of use. The guiding rod 903 and the supporting plate 905 play a guiding role to ensure the smoothness of adjustment. The limiting block 904 arranged at the end of the guiding rod 903 plays a blocking and limiting role to prevent the opening and closing plate 901 from falling off due to excessive adjustment.

[0024] When using the opening and closing assembly 9, the staff drives the footrest 907 through the sole of the foot, so that the cross bar 906 moves on the supporting plate 905, and the connecting rod 902 drives the guiding rod 903 and the opening and closing plate 901 to move, thereby realizing the adjustment of the position of the opening and closing plate 901 and enabling the quick opening and closing of the spraying hopper 8. During this process, the guiding rod 903 and the supporting plate 905 play a guiding and supporting role to ensure the smooth movement of the opening and closing plate 901. The limiting block 904 at the end of the guiding rod 903 can limit the movement during the opening of the opening and closing plate 901 to prevent the opening and closing plate 901 from falling off due to excessive movement. The structure is simple and the use effect is excellent.
