Description

Technical Field

[0001] This utility model specifically relates to the field of road traffic marking technology, and more specifically to a hot-melt type road traffic marking device. Background Technology

[0002] Hot-melt road traffic marking equipment is a professional device used to apply hot-melt markings to the road surface. The process involves first drawing the marking outline on the road surface, then attaching road marking masking tape to the outside of the outline to prevent the paint from being applied outside the markings. Finally, the hot-melt road traffic marking machine is used to apply the paint to the marking area.

[0003] In the hot-melt type road traffic marking machine, the hot-melt kettle melts the solid paint, and then the paint is fed into the marking mechanism by the feeding pump. The paint is then applied to the designated position by the brushing roller in the marking mechanism. In order to increase the reflectivity of the marking, glass beads are also spread on the paint that has not been completely dried to ensure the reflectivity of the road traffic marking.

[0004] However, in practice, it has been noted that in order to ensure the neatness of the edges after the lines are marked, road marking masking tape needs to be laid outside the marked area before the lines are drawn. This work is generally done manually, and the workers need to constantly adjust the position of the road marking masking tape until the edge of the tape is completely aligned with the marked area before it can be pasted onto the ground. This process takes a lot of time, which reduces the efficiency of road marking. Furthermore, the laying process requires workers to squat throughout, which puts a heavy burden on their bodies and increases their labor intensity. Utility Model Content

[0005] The purpose of this invention is to provide a hot-melt type road traffic marking device. The end of the road traffic marking machine is equipped with a front-mounted guide bracket for placing road marking masking tape. When the machine moves, it works with an elastic applicator to automatically apply the masking tape to both sides of the marking, eliminating the need for manual application, thus improving efficiency and reducing the labor intensity of workers.

[0044] In this embodiment, a movable handrail 4 is fixedly connected to the side of the vehicle frame 1, and the direction of the road traffic marking machine is controlled by the movable handrail 4.

[0045] The working principle of this utility model is as follows: First, the road marking masking tape is fitted onto the outside of the support shaft 92. Then, the number of isolation sleeves 94 is adjusted according to the width of the road marking masking tape and its fixed position. Next, the end limiter 93 is fitted onto the end of the support shaft 92, and the end of the guide rod 96 passes through the positioning through hole 932 on the side baffle 931. The end of the road marking masking tape is then placed under the guide rod 96 and around to the bottom of the roller 104. The compression spring 102 applies downward pressure to the swing rod 101, causing the end of the road marking masking tape to adhere to the ground. Then, solid paint is placed into the hot melt kettle 7, which melts the solid paint. The stirring mechanism inside the hot melt kettle 7... The solid paint is stirred to accelerate melting, and then the melted paint is sent to the marking machine 6 through the discharge pump at the bottom of the hot melt kettle 7. The worker controls the direction by holding the moving handle 4. The engine 3 transmits power through the power transmission mechanism 8 and the transmission chain. The paint is applied to the ground by the marking roller rotating inside the marking machine 6. At the same time, as the road traffic marking machine moves, road marking masking tape is gradually pasted onto the ground. After pasting, the road marking masking tape is located on both sides of the marking rollers to prevent excess paint from affecting the marking quality. Glass beads are scattered onto the marking position by the glass bead dispenser 5 to increase the reflectivity of the marking. The structure is simple, the operation is very convenient, and it effectively reduces the labor intensity.
