Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a preparation device and method for hot-melt road marking paint. Background Technology

[0002] Road traffic markings are mainly applied to the road surface and are exposed to sun, rain, wind, snow, ice, and the impact and wear of vehicles. Therefore, their performance is subject to strict requirements. Road markings can be divided into cold paint markings and hot melt markings according to the construction method. Hot melt road paint markings are a commonly used material for road marking. They are usually composed of raw materials such as resin, pigments, and fillers. Hot melt road paint markings are usually prepared in the form of solid powder. During construction, the paint is heated to a certain temperature using a special marking device and sprayed directly or marked on the road surface in conjunction with glass beads to form a complete reflective road marking.

[0003] Chinese Patent Announcement No.: CN 114808650 B, Announcement Date: April 7, 2023. This application proposes a device for high-durability road markings, including the following application steps: S1, pouring the mixed raw materials into the paint tank above the cart, and starting the heating rod to heat the raw materials, while simultaneously starting the dual-shaft motor to drive the stirring rod to rotate and stir, preparing a hot-melt paint; S2, rotating the turntable, driving the rotating rod and transmission rod to rotate, releasing the seal on the guide slide and discharge pipe. The shortcomings of this technical solution are: 1. Due to the stirring method of the stirring rod, the heat source can only be arranged around the tank during preparation and heating, resulting in inconsistent paint temperatures on the inner and outer sides of the tank cavity, reducing efficiency and easily causing localized charring; 2. Direct application of the paint during marking preparation results in the road surface being in a negative state (such as dirt or dampness), affecting the paint's adhesion effect, and lacking assurance of the marking's reflective performance.

[0004] In summary, existing road marking paint preparation devices have shortcomings such as poor preparation effect and difficulty in adapting to road surfaces during marking construction, which reduces the safety of use. Summary of the Invention

[0005] To overcome the shortcomings of existing road marking paint preparation devices, such as poor preparation effect and difficulty in adapting to road surfaces during marking construction, which reduces the safety of use, a hot-melt road marking paint preparation device and preparation method is provided to improve the preparation effect of road marking paint, enhance the applicability of construction to road surfaces, and thus improve the safety of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for preparing hot-melt road marking paint, comprising: A trolley, with a handle at the top and wheels at the bottom that rotate. The working tank is connected to the trolley. The working tank contains a heating component and a stirring component. The working tank is connected to a marking component, which is connected to a feeding box. The impurity removal component is connected to the trolley and is positioned at the front end of the marking component. The material spreading component is connected to a trolley with a storage bin. The material spreading component is connected to the trolley, and the storage bin is connected to the material spreading component. The material spreading component is located at the rear end of the marking component. A material dispensing box, a material dispensing assembly connected to the material dispensing box, and a material dispensing box connected to a moving trolley; The switch plate, the working tank and the storage box are all connected to the discharge seat, and the switch plate is movably connected to the discharge seat. A speed monitoring component is connected to a roller, and a prompter is connected to the handle, which is electrically connected to the speed monitoring component.

[0007] The trolley has a handle at the top and wheels at the bottom for smooth movement on the road. The work tank stores and produces the raw materials for the road marking paint. Heating and stirring components within the work tank ensure efficient and uniform paint production, supplying paint to the feeding box on the marking assembly connected to the outside of the work tank, thus improving the quality of the road marking coating. A dust removal component is connected to the trolley and positioned at the front of the marking assembly to pre-treat the road before marking, ensuring it is in a good working condition and preventing issues such as reduced adhesion, blistering, or premature peeling of the markings from the feeding box from affecting construction quality. A storage bin stores glass beads for reflective marking operations; the spreading component connects to the storage bin for transfer. The device uses a spreading box to evenly distribute glass beads into the coating. The spreading box is adjustable and movable on a trolley to ensure timely application of the glass beads. Premature application in environments with slow-drying coatings results in the beads sinking completely into the paint and losing their reflective properties, while late application in environments with fast-drying coatings leaves the beads unset and easily detached as the coating passes the trolley. Movable switches control the feeding process on both the work tank and storage bin. A speed monitoring component connected to rollers monitors the trolley's speed, alerting the operator to adjust the speed. This improves marking accuracy, prevents uneven or excessively thick / thin lines, and reduces the skill required for marking operations, making the device easy to use. The device achieves the following effects: improved heating efficiency and quality of the marking paint, enhanced marking quality, stable reflectivity of the glass beads for improved road safety, and ease of operation for marking operations.

[0008] Preferably, the heating assembly includes a sleeve and a heating rod. The working tank is connected to a top cover, the surface of which has several evenly staggered mounting holes. The inner bottom of the working tank has a mating hole, with the mounting holes and the mating hole arranged opposite each other. One end of the sleeve is inserted into the mating hole, and the other end of the sleeve is inserted into the mounting hole. The heating rod is inserted into the sleeve. The sleeve in the heating assembly extends from the mounting holes in the top cover and mates with the mating holes in the inner bottom of the working tank, allowing the sleeve to be stably positioned in the working tank and staggered in various locations. This ensures that all the raw materials of the paint in all positions within the working tank are heated by the heating rod inside the sleeve, thereby improving the heating efficiency and uniformity of the marking material within the working tank.

[0009] Preferably, the top cover is connected to a lifting structure. The stirring assembly includes a stirring plate, a guide cylinder, and a guide column. The stirring plate has several clearance holes and flow holes. The stirring plate is connected to the guide cylinder, and the guide cylinder is sleeved with the guide column. A clearance through hole is provided at the center of the top cover. A positioning hole is provided at the bottom of the working tank. One end of the guide column is inserted into the positioning hole, and the other end of the guide column is connected to the top cover. The sleeve is placed between the clearance holes, and the stirring plate is connected to the lifting structure. The stirring plate moves up and down in the working tank through the lifting structure connected to the top cover to agitate the coating raw materials. During movement, it can move along the guide column, thereby improving the stability and guidance of the movement. The clearance holes on the stirring plate allow the stirring plate to move in a staggered manner with the sleeve, and the flow holes make the liquid flow more frequent and the movement of the stirring plate smoother. Ultimately, the continuously flowing raw materials are evenly heated in contact with each heating component. This achieves the effect of improving the heating efficiency and uniformity of the coating.

[0010] Preferably, the lifting structure includes a rotating mechanism, a positioning seat, a connecting rod, and a connecting plate. The rotating mechanism is connected to the positioning seat, one end of which is connected to the top cover. The positioning seat has a guide rail, which communicates with a clearance hole. One end of the connecting rod is connected to the guide cylinder, and the guide cylinder has a guide rail. The guide cylinder is slidably connected to the guide rail. The other end of the connecting rod is connected to one end of the connecting plate. A drive stud is inserted into the top cover and threadedly connected to the connecting plate. The rotating mechanism is connected to the other end of the drive stud. The guide cylinder is connected to the connecting rod, and the other end of the connecting rod passes through the clearance hole and connects to the connecting plate. Driven by the rotating mechanism, the drive screw rotates on the top cover, and the connecting plate, threadedly connected to the drive screw, moves up and down along the drive screw, thereby moving the connecting rod up and down. This causes the stirring plate connected to the internal guide cylinder to move up and down to achieve stirring. The external rotating mechanism facilitates assembly, maintenance, and heat dissipation. This improves the automation efficiency and operational stability of the device.

[0011] Preferably, the marking assembly includes a material guide channel and a marking cylinder. The working tank has a discharge port, the feeding box is connected to a trolley, one end of the material guide channel is connected to the discharge port, and the feeding box is placed below the other end of the material guide channel. The feeding box has a feeding port and a connecting hole. The marking cylinder is connected to a rotating shaft, which is inserted into the connecting hole. The marking cylinder is placed below the feeding port. The material guide channel is connected to the discharge port to transport the heated raw material, allowing the paint to enter the feeding box from the material guide channel. The feeding box feeds the paint onto the marking cylinder through the feeding port. The marking cylinder is connected to the lower end of the discharge port and can be rotated by the rotating shaft to mark lines. The movable marking cylinder switches between contact states with the road surface to achieve the switching of marking states. This achieves the effect of quickly applying paint to the road for marking.

[0012] Preferably, the impurity removal assembly includes a grinding disc and an impurity removal duct. A trolley is connected to a second rotary motor and a hot air blower. The second rotary motor is connected to the grinding disc, and one end of the impurity removal duct is connected to the hot air blower, while the other end is positioned at the rear end of the grinding disc. Driven by the second rotary motor, the grinding disc in the impurity removal assembly cleans the road surface to remove old road lines during re-marking. The hot air blower, through the impurity removal duct, removes dust, dirt, oil, and moisture from the road surface, thereby improving the adhesion of the painted line markings and reducing blistering or peeling. This achieves efficient ground pretreatment and further improves the construction quality of the painted line markings.

[0013] Preferably, the storage box is equipped with a flow port, and the dispensing assembly includes a feed hose and a distribution plate. One end of the feed hose is connected to the flow port, and the other end is connected to the dispensing box. The dispensing box has a dispensing port and a positioning slot. The distribution plate is inserted into the positioning slot and has several dispensing holes, which are placed inside the dispensing port. The storage box feeds glass beads from the feed hose into the dispensing box through the flow port, and then the dispensing port sends the glass beads out through the dispensing holes of the distribution plate. This ensures that the glass beads are evenly distributed on the marking paint, increasing the reflectivity of the paint and preventing the "starry sky effect" of alternating bright and dark reflections at night. This achieves the effect of uniformly distributing the glass beads on the marking surface, improving the uniformity of the reflective surface, and thus enhancing safety during use.

[0014] Preferably, the inner bottom of the spreading box is connected to a guide plate, the trolley is connected to an adjusting rod, and the spreading box is connected to an adjusting slider. The adjusting slider is inserted into the adjusting rod, and the adjusting rod has external threads. A limit slider is threaded onto the adjusting rod, and the limit slider is located on both sides of the adjusting slider. The guide plate on the inner bottom of the spreading box ensures a more even distribution of glass beads flowing from the feed hose. Furthermore, the spreading box adjusts the distance between the feed and the glass beads by sliding the adjusting slider on the adjusting rod, and is fixed by the limit slider. This results in a more rational combination of physical anchoring and chemical bonding between the hot-melt marking and the road surface. This achieves the effect of quickly and stably adjusting the spreading timing to adapt to the state of the paint and ensuring good reflective quality.

[0015] Preferably, the speed monitoring component includes a sensor, a control system, and a potentiometer. The sensor is connected to the roller, the control system is connected to the trolley, and the potentiometer and indicator are both connected to the handle. The sensor, potentiometer, and indicator are all electrically connected to the control system. The sensor in the speed monitoring component is connected to the roller to monitor the trolley's movement speed. The potentiometer, through a speed setting, and the indicator are electrically connected to the control system. After the sensor transmits the actual speed of the trolley to the control system, any deviation between the actual speed and the set speed will be indicated by the indicator. This prevents the paint lines from being drawn too quickly or too slowly, which could result in substandard paint line thickness. Simultaneously, the device is easier to use, reducing the skill requirement. This achieves the effect of reducing the difficulty of device construction and improving work quality.

[0016] A method for preparing hot-melt road marking paint includes the following steps: S1: Inside the working tank, the raw materials are heated and stirred by heating rods and stirring plates, and the position of the feeding box is adjusted; S2: Push the cart to the marked road, turn on the grinding disc and hot air blower to clean the road in the cart, and pay attention to the speed monitoring status of the indicator while moving; S3: Open the work tank to allow the paint to flow from the feed box to the marking cylinder for marking. Pay attention to the speed monitoring status of the indicator while moving. S4: Open the storage box to spread glass beads onto the road marking paint using the spreading box. While moving, pay attention to the speed monitoring status of the indicator. S5: Close the supply of materials to the spreading box, feeding box, working tank and storage box to complete the paint marking construction.

[0017] Specific operating procedures: Pre-adjust the position of the spreading box on the adjusting rod according to the ambient temperature, and set the trolley's travel speed using the potentiometer. After the marking paint material is added to the working tank, energize the heating plate and rotating mechanism one. This causes the stirring plate to move up and down within the working tank due to the drive screw's influence on the connecting plate, thus agitating the material during heating. Heat to the marking temperature and maintain it. On the road to be marked, activate rotating mechanism two to clean the ground with the abrasive disc. Simultaneously, turn on the hot air blower to blow air through the impurity removal fan, cleaning the road surface. The cleaned surface is then ready for marking. Rotate the side plate to expose the feeding port, opening switch one to allow paint to flow from the outlet into the guide channel. Paint is then supplied to the marking cylinder from the feeding port of the feeding box, propelling the trolley for marking. Simultaneously with marking, open switch two to allow the feeding pattern tube to deliver glass beads into the spreading box. These glass beads are then spread outwards through the spreading holes of the equalizing plate, supplementing the reflective function of the marking paint. Pay attention to the pushing speed while the cart is moving, and adjust the cart speed based on sensor feedback to ensure that the paint applied to the marking lines is uniform.

[0018] The beneficial effects of this invention are: improving the heating efficiency and quality of the marking paint in the preparation device; improving the construction quality of marking; achieving uniform distribution of glass beads on the marking surface to improve the uniformity of the reflective surface and thus improve the safety of use; making the preparation device easy to operate for marking operations; improving the heating efficiency and uniformity of the marking material in the working tank; and improving the automation efficiency and stability of the device preparation.

[0031] like Figure 1-7 As shown: The discharge seat includes discharge seat one 51 and discharge seat two 52, and the switch plate includes switch plate one 53 and switch plate two 54.

A steel wool ball is installed on the side of the grinding disc 34 facing the ground to remove the paint from the ground.

[0034] This application also provides a method for preparing hot-melt road marking paint, comprising the following steps: S1: In the working tank 4, the raw materials are heated and stirred by the heating rod 10 and the stirring plate 14, and the position of the feeding box 7 is adjusted. S2: Push the cart 1 to the marked road, turn on the grinding disc 34 and the hot air blower 37 to clean the road in the cart 1, and pay attention to the speed monitoring status of the indicator 8 while moving. S3: Open the work tank 4 to allow the paint to flow from the feed box 5 to the marking cylinder 29 for marking. Pay attention to the speed monitoring status of the indicator 8 while moving. S4: Open the storage box 6 to spread glass beads onto the marking paint using the spreading box 7. Pay attention to the speed monitoring status of the indicator 8 while moving. S5: Close the material supply of the spreading box 7, feeding box 5, working tank 4 and storage box 6 to complete the paint marking construction.

[0035] In actual use: adjust the position of the spreading box 7 on the adjusting rod 45 in advance according to the weather and ambient temperature, and set the traveling speed of the trolley 1 through the potentiometer 50.

[0036] After the marking paint raw material is added to the working tank 4, the heating plate 10 and the rotating mechanism 21 are energized, causing the stirring plate 14 to move up and down in the working tank 4 due to the drive of the connecting plate 24 by the drive stud 27, thereby stirring the raw material during heating.

[0037] Heating to the marking temperature and maintaining it, the rotating mechanism 36 is activated on the road to be marked, causing the grinding disc 34 to clean the ground. Simultaneously, the hot air blower 37 is turned on, and the cleaning air duct 35 blows air onto the ground to clean it. The cleaned road surface is then ready for marking. Rotating the side plate 57 exposes the feed port 31, opening the switch plate 53 to allow paint to flow from the discharge port 30 into the guide channel 28. Paint is then supplied from the feed port 31 of the feed box 5 to the marking cylinder 29 to push the trolley for marking.

[0038] While marking lines, switch plate 2 54 is turned on, causing the feed pattern tube 39 to deliver glass beads through the feed hose 39 to the spreading box 7. The glass beads are then spread outwards through the spreading holes 43 of the uniform plate 40 onto the marking paint to supplement the reflective function. During the movement of the trolley 1, the pushing speed is monitored, and the trolley speed is adjusted based on feedback from the sensor 48 to ensure that the paint applied to the marking lines is uniform.

[0039] After the marking is completed, the discharge of the working tank 4 and the storage box 6 is closed by telescopic mechanism 1 55 and telescopic mechanism 2 56. The marking cylinder 29 is moved up away from the road surface and the feeding port 31 is blocked. The cylinder is then moved down and inserted into the positioning slot 42 to block the feeding port 41 of the material distribution plate 40 without the sprinkling hole 43, thus ending the marking operation.
