[0002] The hot melt marking dotting and line breaking equipment is designed specifically for road marking operations. It uses hot melt technology to firmly lay the marking material on the road surface, thereby creating eye-catching traffic guiding lines. In actual operation, this equipment often works in coordination with sandblasting equipment to achieve the function of dotting and line breaking. However, there is a significant technical challenge to overcome: during operation, it is very difficult to ensure that the distance between the line breaking points is completely accurate. This may result in uneven spacing in the dotted line part of the line break, thereby affecting the overall quality of the product. Because when the line break spacing is uneven, both the mechanical properties and visual effects of the marking material may not meet the established standards, potentially affecting road safety and aesthetics.

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the detailed implementation mode.

[0022] As Figure 1 - Figure 4 shown, this device is a dotted line dotting and line breaking device dedicated to marking construction, and its detailed structure and functions are described as follows. All key components are attached with digital marks for easy identification and description:

[0023] The base 1 serves as the basic support structure of the entire device, and the design of the base 1 is stable and easy to operate. The movable wheel 2 is ingeniously installed at the rear end of its lower end, which enables the entire device to move easily within the working area, ensuring that the sandblasting head 8 can travel precisely along the marking line.

[0024] The hand-held support frame 3 is firmly fixed to the upper edge of the base 1 by welding technology, providing a stable support platform for the entire device. The hand-held support frame 3 not only enhances the structural strength of the device but also facilitates the hand-held control by the operator.

[0025] The storage tank 4 is installed between the hand-held support frame 3 and the base 1 for storing the medium required for sandblasting. The storage tank 4 is fixed to the hand-held support frame 3 by a special clamping ring to ensure its stability during the working process.

[0026] The air pump connecting pipe 5 is a key component connecting the air pump and the storage tank 4. The air pump connecting pipe 5 is connected to the storage tank 4 and the three-way pipe 7 through the valve 6. The precise control of the valve 6 ensures the smooth flow and precise adjustment of the sandblasting medium.

[0027] The three-way pipe 7 is designed to direct the sandblasting medium in the storage tank 4 to the sandblasting head 8. One end of the three-way pipe 7 is connected to the storage tank 4, and the other end is connected to the sandblasting head 8 through a hose, realizing the long-distance transmission and precise spraying of the sandblasting medium.

[0028] The sandblasting head 8 is the core component for realizing the dotting and line breaking function. The sandblasting head 8 is tightly connected to the three-way pipe 7 through a hose. The anti-slip rubber sleeve sleeved on its side wall not only improves the comfort of holding but also enhances the safety of operation. The fastening of the sandblasting head 8 depends on the clamp 14 installed on the adjustment frame 11 and the fastening bolt 15 thereon.

[0029] The mounting bracket 9 and the adjustment frame 11. The mounting bracket 9 is installed in the middle of the front end of the base 1 and is used to support and adjust the frame 11. The adjustment frame 11 can move along the mounting bracket 9 and is fixed by inserting bolts into the mounting holes 10. This design enables the extended length of the adjustment frame 11 to be flexibly adjusted according to actual needs.

[0030] The bulletproof glass 12 and the scale 13. The bulletproof glass 12 is embedded inside the adjustment frame 11, which not only improves the safety performance of the observation structure but also prevents accidental breakage that may occur during sandblasting operations. The scale 13 set on the bulletproof glass 12 is in proportion to the distance from the dotted line, providing an intuitive reference basis for the operator.

[0031] This dotted line dotting and breaking device realizes precise control and efficient operation of the marking construction through the precise cooperation and optimized design of various components.

[0032] Working process: The operator fills the medium required for the marking construction into the storage tank 4. Turn on the air pump, and convey compressed air into the storage tank 4 through the air pump connecting pipe 5. The gas, through the precise control of the valve 6, pushes the sandblasting medium in the storage tank 4 to flow towards the tee pipe 7. The tee pipe 7 guides the sandblasting medium to the sandblasting head 8. The sandblasting head 8 moves along the predetermined marking under the control of the operator, and realizes the dotted line dotting and breaking function by spraying the sandblasting medium.

[0033] Adjustment process: According to the construction requirements, the operator adjusts the extended length of the sandblasting head 8 by moving the adjustment frame 11. The adjustment frame 11 is supported by the mounting bracket 9, moves along it and is fixed by inserting bolts into the mounting holes 10 to achieve the required extended length. By observing the scale 13 on the bulletproof glass 12, the operator can precisely adjust the distance between the sandblasting head 8 and the marking to ensure the uniformity and accuracy of the dotted line. During the entire operation process, the operator can adjust the valve 6 according to the actual situation to control the flow rate of the sandblasting medium to achieve the best construction effect.

[0034] The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the records in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the existing technology. The machines, parts, and equipment all adopt conventional models in the existing technology, and the electrofusion connection adopts the conventional connection method in the existing technology, which will not be elaborated here.

[0035] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should all be covered within the protection scope of the present utility model.
