Description

Technical Field

[0001] This utility model relates to the technical field of road marking equipment, specifically a hot-melt autoclave device for hot-melt road marking. Background Technology

[0002] Road markings are information markers on road surfaces, including lines, arrows, text, vertical markings, raised pavement markers, and delineators, used to guide traffic flow, indicate driving directions, and warn of road conditions. Traditional road marking machinery operates by first heating and stirring powdered paint in a hot-melt kettle until it melts, then pouring the molten material into the marking machine for application. However, the amount of paint needed for typical marking operations cannot be loaded into the machine all at once, leaving some in the hot-melt kettle. If heating stops in the kettle, the paint may cool and solidify, affecting its usability. Therefore, current technology uses constant-temperature heating in the hot-melt kettle to reduce paint waste.

[0003] Existing hot-melt autoclave equipment for road markings has several drawbacks, such as: powder coatings are typically added manually to the autoclave, generating significant dust and being environmentally unfriendly, especially during operation when replenishing the autoclave at high temperatures, impacting worker health; existing temperature gauges are located above the autoclave, and dust and steam affect their accuracy and structural stability, leading to inaccurate temperature control and inconsistent material consistency, requiring operators to rely on experience to judge the material processing, affecting output quality and resulting in poor line smoothness and appearance, limited material flowability, pinholes, reduced adhesion, and reduced lifespan of the markings; discharging requires manual operation of the autoclave's outlet opening and closing and hopper position adjustment, which is inconvenient.

[0004] Therefore, a hot melt kettle is needed for processing road marking paint, which facilitates feeding and discharging of materials, and controls the temperature of the liquid during heating to achieve the optimal consistency. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] An embodiment of this utility model provides a hot-melt autoclave device for hot-melt road markings, such as... Figure 1-8 As shown, the system includes a material storage and feeding module, a hot-melt module, an output module, a power module, and a controller.

The drive mechanism is a linear drive mechanism, which moves the door panel 41 linearly to adjust the area of ​​obstruction to the output port.

[0033] Preferably, the drive mechanism includes a drive motor 42, a drive frame 43, and a gear and rack assembly. The drive frame 43 is fixedly mounted above the output port and has a mounting groove. The rack 45 is vertically slidably disposed within the mounting groove, and the bottom of the rack 45 is fixed to the door panel 41.

The drive motor 42 is located on one side of the drive frame 43 and drives the gear 44 to rotate synchronously. The gear 44 drives the rack 45 to move, and the rack 45 drives the door panel 41 to move up and down.

[0034] The flow guiding assembly includes a flow guiding channel 52 and a driving hydraulic cylinder 5. The flow guiding channel 52 has a concave design, and a rotating sleeve is provided at the inlet end of the flow guiding channel 52. The flow guiding channel 52 is rotatably sleeved on the lower part of the outer shell 3, and a rotating lug 53 is provided on the side wall of the flow guiding channel 52. Each flow guiding channel 52 corresponds to two sets of driving hydraulic cylinders 5. The top end of each driving hydraulic cylinder 5 is rotatably connected to the mounting base 51 provided on the outer shell 3 through a hinge mechanism. The lower end of the driving hydraulic cylinder 5 is hinged to the rotating lug 53. The driving hydraulic cylinder 5 is driven by the power module to extend and retract its motion guide rod, so that the flow guiding channel 52 rotates upward to a position close to the outer shell 3 to form a retracted state, or rotates downward to a working state where the feed end of the flow guiding channel 52 connects with the output port and the discharge end reaches a set position.

[0035] The power module includes a diesel engine 6, a generator 7, an oil pump 8, and an electronic flow control valve 9. The power module also includes a storage battery. The power module is controlled by the controller. After starting, the diesel engine 6 drives the generator 7 to generate electricity or replenish the storage battery. The diesel engine 6 drives the oil pump 8 to supply pressure, and the flow control valve distributes the pressurized hydraulic oil from the oil pump 8 to the hydraulic motor 33 and the drive hydraulic cylinder 5. The electronic flow control valve 9 is electrically connected to the controller, and the start and stop of corresponding mechanisms are achieved by adjusting the switches of different hydraulic oil flow paths.

[0036] Working process: The powdered hot melt material is pre-stored in the corresponding storage tanks 1. In use, the feeder 2 is started, lifting the hot melt material above the outer shell 3. Through the interface, the powdered hot melt material is fed into the inner cavity of the inner vessel 31. It exchanges heat with the outer vessel after being heated by the burner, melting the hot melt material. The initially melted hot melt material is then uniformly heated by the stirring blades 35 driven by the hydraulic motor 33, forming a liquid hot melt material of appropriate viscosity. The temperature sensor 32 installed in the inner vessel 31 provides feedback on the heating temperature, and the controller adjusts the burner power based on the measured temperature data.

[0037] When the hot melt material reaches the marking temperature, the driving hydraulic rod is activated as needed to lower the guide channel 52. The operator aligns the material tank of the marking device with the end of the guide channel 52. Further, the controller is operated to start the drive motor 42, opening the door panel 41, allowing the molten hot melt material to flow out of the inner vessel 31 along the guide channel 52.

[0038] The two sets of inner vessel bodies 31 are independent of each other to meet the requirements of two-color and same-color melting and simultaneous feeding from both sides.
