Description

Technical Field

[0001] The present invention relates to the technical field of road markings, and particularly relates to a marking paint equipment and a paint preparation method. Background Art

[0002] Road markings are mainly drawn on the road surface to regulate the passage of vehicles and pedestrians, enabling them to stay in their respective lanes without interference and ensuring smooth traffic safety. Due to exposure to sunlight, rain, snow, ice, and vehicle impact and abrasion, strict requirements are imposed on their performance. Firstly, it is required to have a short drying time and simple operation to reduce traffic interference; secondly, it is required to have strong reflection ability, distinct color, and high reflectivity to ensure good visibility during both day and night; thirdly, it should have anti-slip and wear-resistant properties to ensure driving safety and service life.

[0003] Existing hot-melt marking paint equipment has a single function. When drawing solid lines, dashed lines, and oscillating markings, it is necessary to replace the corresponding marking buckets, which is rather cumbersome to use.

[0004] Therefore, it is necessary to provide a new type of marking paint equipment. Summary of the Invention

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present invention is to provide a marking paint equipment with diverse functions, making the construction simpler and more convenient.

[0006] The technical solution adopted by the present invention is: a new type of functional nylon marking paint, including modified petroleum resin, petroleum resin, EVA resin, polyamide resin, filler, pigment, plasticizer, fiber, internal mixing reflective glass beads, and surface scattering reflective glass beads.

[0007] Further, the petroleum resin is a mixture of aliphatic resin and aromatic resin in a mass ratio of 1:2.

[0008] Further, the modifiers of the modified petroleum resin include SBS and epoxy acrylate.

[0009] The present invention also provides a paint preparation method applicable to the above new type of functional nylon marking paint, including the following steps:

[0010] Add the modified petroleum resin, petroleum resin, EVA resin, polyamide resin, filler, pigment, plasticizer, short fiber, and internal mixing reflective glass beads to a stirring kettle and stir evenly.

[0011] To achieve the above object, the present invention also provides a marking paint device, which is applicable to the above-mentioned new functional nylon marking paint. The marking paint device includes a vehicle frame, a marking hopper installed on the vehicle frame, a first wire tube, and a control rod. The marking hopper includes a hopper, a gate, a push block, and a first connection end. The gate is rotatably installed on one side of the hopper. When the gate is opened, a marking opening can be exposed at the bottom of the hopper. The push block is rotatably installed on the hopper. Rotating the push block can open the gate to open the marking opening. The first connection end is installed on the hopper. The control rod is connected to the hopper. A handle seat is installed on the control rod, and a handle is movably arranged on the handle seat. The two ends of the first wire tube are respectively connected to the handle seat and the first connection end. A first pulling rope is inserted into the first wire tube.

The marking paint device further includes a second connection end installed on the vehicle frame.

[0014] Further, the two ends of the first wire tube can be respectively connected to the second connection end and the first connection end. The two ends of the first pulling rope are respectively connected to the push block and the swing rod. Thus, when the swing rod swings, the first pulling rope is pulled to drive the push block to rotate. Along with the reciprocating swing of the swing rod, the gate is driven to be intermittently opened and closed.

[0015] Further, a tooth groove is provided at a position near the bottom of the gate. The marking hopper further includes a scraping plate, a fixed seat, and a swing arm. The scraping plate is slidably installed on the outer end face of the gate so that when the scraping plate reciprocates on the gate, the tooth groove can be opened and closed. The fixed seat is located on one side of the hopper and is fixedly connected to the gate. The swing arm is rotatably installed on the fixed seat, and the swing arm is connected to the scraping plate.

The marking paint device further includes a second wire tube. The two ends of the second wire tube can be respectively connected to the third connection end and the second connection end on the vehicle frame. A second pulling rope is inserted into the second wire tube. The two ends of the second pulling rope are respectively connected to the swing arm and the swing rod.

[0016] Further, an elastomer is installed between the swing arm and the fixed seat. The elastomer is used to apply an elastic force to the swing arm so that the swing arm always has a tendency to rotate and drive the scraper plate to close.

[0017] The beneficial effects of the present invention are as follows: A road marking paint equipment provided by the present invention includes a vehicle frame, a marking hopper, a first wire tube, and a control rod installed on the vehicle frame. The marking hopper includes a hopper, a gate, a push block, and a first connection end. The gate is rotatably installed on one side of the hopper. When the gate is opened, a marking opening can be exposed at the bottom of the hopper so that the road marking paint in the hopper can flow out through the marking opening to complete the marking. The push block is rotatably installed on the hopper. Rotating the push block can open the gate to open the marking opening. The first connection end is installed on the hopper. The control rod is connected to the hopper. A handle seat is installed on the control rod, and a handle is movably arranged on the handle seat. The two ends of the first wire tube are respectively connected to the handle seat and the first connection end. A first pull rope is inserted into the first wire tube.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0036] Reference to "one embodiment" or "an embodiment" throughout the specification means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the phrases "in one embodiment", "in some embodiments", or "in some of these embodiments" appearing throughout the specification do not necessarily refer to the same embodiment. Additionally, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0037] Referring to Figures 1-9 As shown, an embodiment of the present invention provides a marking paint device, including a vehicle frame 100, a marking hopper 200 mounted on the vehicle frame 100, a first wire tube 400, and a control rod 600. The marking hopper 200 includes a hopper 210, a gate 220, a push block 230, and a first connection end 240. The gate 220 is rotatably mounted on one side of the hopper 210. When the gate 220 is opened, a marking opening 290 can be exposed at the bottom of the hopper 210 so that the marking paint in the hopper 210 can flow out through the marking opening 290 to complete the marking. The push block 230 is rotatably mounted on the hopper 210. Rotating the push block 239 can open the gate 220 to open the marking opening 290. The first connection end 240 is mounted on the hopper 210. The control rod 600 is connected to the hopper 210. A handle seat 610 is mounted on the control rod 600, and a handle 620 is movably arranged on the handle seat 610. Both ends of the first wire tube 400 are respectively connected to the handle seat 610 and the first connection end 240. A first pulling rope 410 is inserted into the first wire tube 400. Both ends of the first pulling rope 410 are respectively connected to the push block 230 and the handle 620. Thus, by operating the handle 620, the first pulling rope 410 can be pulled to drive the push block 230 to rotate, and the push block 230 rotates to open the gate 220. Through the above technical solution, the user can freely control the opening and closing of the marking opening 290 through the handle 620 on the control rod 600. Furthermore, not only can it facilitate continuous feeding to draw a solid line, but also a dotted line can be drawn by intermittently opening the marking opening 290. It has various functions and is convenient for construction.

[0038] As Figure 1As shown, in some of these embodiments, a paint bucket 110 for storing marking paint is installed on the vehicle frame 100. An outlet 111 is provided on the paint bucket 110, and a connecting hopper 112 is correspondingly installed at the outlet 111 of the paint bucket 110. The end of the connecting hopper 112 extends above the marking hopper 200, so that the connecting hopper 112 can drain the marking paint in the paint bucket 110 into the hopper 210 of the marking hopper 200. Thus, the paint bucket 110 can be used to supply materials to the marking hopper 200 for a long time, ensuring the working efficiency.

[0039] In some of these embodiments, a heating assembly (not shown in the figure) is installed on the vehicle frame 100. The heating assembly is used to keep the paint bucket 110 and the marking hopper 200 warm and heated to ensure that the marking paint remains in a fluid state for a long time.

[0040] As Figure 6 shown, in some of these embodiments, the hopper 210 has a structure with an open top, and an opening 211 is provided on one side of the hopper 210. The gate 220 is correspondingly installed at the opening 211 of the hopper 210 to block the opening 211 through the gate 220. The upper side of the gate 220 is hinged to the hopper 210. When the gate 220 rotates on the hopper 210, the lower side of the gate 220 will significantly separate from the hopper 210, so that a strip-shaped marking opening 290 is exposed at the bottom of the hopper 210. As the marking paint equipment moves forward, the marking paint flowing out of the marking opening 290 shows the required marking shape on the ground.

[0041] Refer to Figure 7 shown, in some of these embodiments, the push block 230 is located on the outer wall of the hopper 210 adjacent to the gate 220. When the push block 230 rotates and gradually approaches the gate 220, the gate 220 is pushed by the push block 230 to rotate and open. When the push block 230 rotates and gradually moves away from the gate 220, the gate 220 can rotate and close.

[0042] As Figure 8 shown, in some of these embodiments, the marking hopper 200 further includes an elastic member 250. The elastic member 250 is used to apply an elastic force to the gate 220 so that the gate 220 always has a tendency to rotate and close. The elastic member 250 is located on the side of the gate 220 close to the opening 211 of the hopper 210. The elastic member 250 is connected between the hopper 210 and the gate 220 in a stretched state, so that the elastic restoring force of the elastic member 250 always pulls the gate 220 to rotate towards the opening 220, so that when the gate 220 loses the thrust of the push block 230, it can automatically close. In this embodiment, the elastic member 250 is a spiral spring.

[0043] As Figure 2 and Figure 3As shown, in some of these embodiments, traveling wheels 120, a gearbox 130 fixedly mounted on a frame 100, a transmission structure 140, a cam 150, and a swing rod 160 are mounted on the frame 100. The traveling wheels 120 are used to roll on the ground. The transmission structure 140 is used to connect the input end of the gearbox 130 and the traveling wheels 120, so that when the traveling wheels 120 rotate, they drive the gearbox 130 to operate synchronously, and the input speed is changed to the required speed through the gearbox 130 and output from the output end of the gearbox 130. The cam 150 is fixedly mounted on the output end of the gearbox 130, so that the cam 150 can rotate synchronously with the traveling wheels 120 at a corresponding speed. The swing rod 160 is rotatably fitted on the frame 100. One end of the swing rod 160 is in contact with the circumferential side wall of the cam 150. When the cam 150 rotates, the corresponding end of the swing rod 160 swings reciprocally along with the rotation of the cam 150. The marking paint device further includes a second connection end 300 mounted on the frame 100. It can be understood that in some other embodiments not shown in the figures, both ends of a first wire tube 400 can be respectively connected to the second connection end 300 and a first connection end 240, and both ends of a first pull rope 410 are respectively connected to a push block 230 and the swing rod 160. Thus, when the swing rod 160 swings, it pulls the first pull rope 410 to drive the push block 230 to rotate. Along with the reciprocal swing of the swing rod 160, the gate 220 is driven to be intermittently switched, so that the marking hopper 200 can automatically draw dotted lines as the marking paint device advances, without the user controlling the handle 620 on the control lever 600. It should be understood that when drawing dotted lines, the interval distance of the markings should be adjusted according to actual needs by adjusting the output speed of the gearbox 130, so that the cam 150 can rotate at the required speed, and the on-off interval duration of the gate 220 will be adjusted, achieving the purpose of adjusting the interval distance of the dotted lines.

[0044] As Figure 6As shown, in some of these embodiments, a toothed groove 222 is provided at a position near the bottom on the gate 220, which is used to cooperate with the scribing opening 290 to scribe the bumps in the oscillating marking line. The scribing hopper 200 further includes a scraper plate 260, a fixed seat 270, and a swing arm 280. The scraper plate 260 is slidably mounted on the outer end face of the gate 220 in the vertical direction, so that when the scraper plate 260 reciprocates on the gate 220, the toothed groove 222 can be opened and closed. When the toothed groove 222 is opened, the marking paint flows out from the toothed groove 222 to form the bumps in the oscillating marking line. The fixed seat 270 is located on one side of the hopper 210 and is fixedly connected to the gate 220. The swing arm 280 is rotatably mounted on the fixed seat 270, and the swing arm 280 is connected to the scraper plate 260. Rotating the swing arm 280 can drive the scraper plate 260 to slide on the gate 220. A third connection end 271 is also mounted on the fixed seat 270 corresponding to the swing arm 280. The marking paint device further includes a second wire tube 500. The two ends of the second wire tube 500 can be respectively connected to the third connection end 271 and the second connection end 300 on the vehicle frame 100. A second pull rope 510 is inserted into the second wire tube 500. The two ends of the second pull rope 510 are respectively connected to the swing arm 280 and the swing rod 160. Thus, when the swing rod 160 swings, the second pull rope 510 can be pulled to drive the swing arm 280 to rotate on the fixed seat 270. Along with the reciprocating swing of the swing rod 160, the scraper plate 260 on the gate 220 is intermittently opened and closed, and in cooperation with the forward movement of the marking paint device, the bumps in the oscillating marking line are scribed on the ground. Since the fixed seat 270 is fixedly matched with the gate 220, the rotation of the gate 220 will not affect the opening and closing of the scraper plate 260. In this way, while opening the scribing opening 290 to scribe the bottom line in the oscillating marking line on the ground, the scraper plate 260 can be controlled to be intermittently opened and closed to scribe the bumps in the oscillating marking line on the bottom line. Compared with the traditional scribing hopper, the structure is simpler and the cost is lower. It should be understood that when scribing the oscillating marking line, the interval distance between the bumps in the oscillating marking line should be adjusted according to the actual needs by adjusting the output speed of the gearbox 130, so that the cam 150 can rotate at the required speed, and then the opening and closing interval duration of the scraper plate 260 will be adjusted to achieve the purpose of adjusting the interval distance between the bumps in the oscillating marking line. The specifications of the toothed groove 222 on the gate 220 are also selected according to the actual needs. Replacing the gate 220 with different specifications can meet the scribing requirements of different forms of oscillating marking lines.

[0045] As Figure 6 shown, in some of these embodiments, slide rails 221 are respectively provided on opposite sides of the outer end face of the gate 220. The scraper plate 260 can be slidably fitted in the slide rails 221 on both sides, so that the scraper plate 260 is slidably fitted on the gate 220 and is close to the toothed groove 222 on the gate 220.

[0046] In some of these embodiments, an elastomer (not shown in the figure) is installed between the swing arm 280 and the fixed seat 270. The elastomer is used to apply an elastic force to the swing arm 280 so that the swing arm 280 always has a tendency to rotate and drive the scraper plate 260 to close, ensuring that the scraper plate 260 automatically closes when not driven by an external force. In some of these embodiments, the elastomer is a torsion spring installed at the pivot point of the swing arm 280.

[0047] As Figure 8 shown, in some of these embodiments, a pin shaft 261 is provided on one side of the scraper plate 260 corresponding to the swing arm 280. A sliding hole 281 is formed on the swing arm 280. The pin shaft 261 is inserted into the sliding hole 281 on the swing arm 280. When the swing arm 280 rotates, the pin shaft 261 adaptively adjusts its position in the sliding hole 281 and remains pushed by the swing arm 280, so that the rotation of the swing arm 280 drives the scraper plate 260 to slide on the gate 220.

[0048] In some of these embodiments, a suspension rod 212 is provided on one side of the hopper 210, and a connecting rod 170 is correspondingly provided on the vehicle frame 100. The suspension rod 212 is rotationally matched with the connecting rod 170. Thus, when the control lever 600 is manipulated, the hopper 220 can be driven to swing up and down around the connecting rod 170, so that the hopper 220 is lifted off the ground when not in use and can be placed against the ground when marking lines.

[0049] In some of these embodiments, the first wire tube 400 and the second wire tube 500 are made of wire braiding. The first pull rope 410 and the second pull rope 510 are also made of wire braiding. They are rigid and can be bent while having a constant length. Thus, the positions of both ends of the first wire tube 400 and the second wire tube 500 can be flexibly changed, which is beneficial to the disassembly and assembly of the wire tubes. At the same time, the structure is simple and the cost is low.

[0050] The present invention also provides a novel functional nylon marking paint, and the above-mentioned marking paint equipment is applicable to this novel functional nylon marking paint. The novel functional nylon marking paint includes modified petroleum resin, petroleum resin, EVA resin, polyamide resin, filler, pigment, plasticizer, fiber, in-mixed reflective glass beads, and surface-sprinkled reflective glass beads. The marking paint comprises the following raw materials: 15-20 parts of modified petroleum resin, 10-15 parts of petroleum resin, 3-5 parts of EVA resin, 5-10 parts of polyamide resin, 50-80 parts of filler, 2-10 parts of pigment, 0.2-2 parts of plasticizer, 1-3 parts of fiber, 20-30 parts of in-mixed reflective glass beads, and 15-25 parts of surface-sprinkled reflective glass beads. In the modified petroleum resin, the weight ratio of petroleum resin, SBS, and epoxy acrylate is 100:100-150:0.6-1. The filler is a compound of ordinary filler and functional filler. The ordinary filler includes at least one of calcium carbonate, barium sulfate, mica powder, and quartz sand. The functional filler is SiO2 hollow microspheres, the outer diameter of the SiO2 hollow microspheres is 20-40 μm, and the inner diameter of the SiO2 hollow microspheres is 2-4 μm; the weight ratio of the ordinary filler to the functional filler is 1-3:1.

[0051] In some embodiments, the petroleum resin is a mixture of aliphatic resin and aromatic resin in a mass ratio of 1-2:2-1.

[0052] In some embodiments, the modifiers of the modified petroleum resin include SBS and epoxy acrylate.

[0053] The present invention also provides a method for preparing the paint applicable to the above-mentioned novel functional nylon marking paint, including the following steps:

[0054] Add the modified petroleum resin, petroleum resin, EVA resin, polyamide resin, filler, pigment, plasticizer, short fiber, and in-mixed reflective glass beads to a stirring kettle and stir evenly. When in use, transfer the marking paint in the stirring kettle to the material bucket 110 of the above-mentioned marking paint equipment, and carry out the marking work through the scribing hopper 200.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
