Description

Technical Field

[0001] This invention belongs to the field of road marking spraying technology, specifically a road marking rain and night reflective layer spraying machine and spraying method. Background Art

[0002] Road markings are important markers for vehicles to stay in their lanes. By planning road markings, roads can be divided into multiple lanes, preventing vehicles from driving haphazardly and causing safety accidents. Existing road markings usually do not have reflective properties, making them difficult to see in rainy weather and at night, posing a significant safety hazard. By using a spraying machine to apply reflective materials to road markings, the markings can be made reflective, allowing vehicles to judge the vehicle's position and avoid safety accidents.

[0003] In existing technologies, intelligent road marking spraying devices generally include a base, on which a stirring mechanism and a corresponding spraying mechanism are mounted. The stirring mechanism includes a housing fixed to the upper surface of the base. The bottom wall of the housing's inner cavity is rotatably connected to a rotating rod via bearings. A casing is fixed to the lower surface of the base. The housing stores the paint raw materials, which react directly inside the device. The paint raw materials in the housing's inner cavity are heated by a heating wire, melting them into a fluid. The rotating rod of the stirring mechanism then stirs the paint raw materials in the housing's inner cavity, keeping the paint in a molten and flowing state, thereby achieving smooth spraying.

[0004] The aforementioned technical solutions, by setting up a heating structure and a stirring mechanism, can assist in heating the internal coating and keeping it in a flowing state, thus ensuring smooth spraying. However, the existing spraying mechanism has a fixed structure and cannot be folded. Some spraying machines that require the installation of multiple spraying mechanisms occupy a large space, making them inconvenient to move and transport. At the same time, they cannot flexibly switch the orientation of the spraying mechanism according to different spraying needs. Summary of the Invention

The screw slider is slidably installed on the outside of the limiting guide rods. A limiting shaft is welded and installed between the screw slider and the strip slider. The guide plate is rotatably installed on the outside of the limiting shaft.

[0009] Preferably, a C-shaped bracket is installed at the end of the guide plate away from the limiting shaft, and a reinforcing corner seat is welded to the inner side of the C-shaped bracket and the guide plate. Several sets of positioning tooth grooves are opened on the side of the C-shaped bracket away from the middle, and an adjustment and collection component is slidably arranged on the outer side of the end of the C-shaped bracket.

[0010] Preferably, the regulating collection assembly includes an regulating plate, and an regulating screw is rotatably mounted on the top of the regulating plate. An regulating knob is installed on the top of the regulating screw, and a movable plate is rotatably mounted on the outer side of the regulating screw. Fixed transmission pipes are fixedly mounted on the inner sides of both ends of the movable plate, and H-shaped nozzles are installed at the bottom of the fixed transmission pipes. A splicing plate is spliced ​​on the front and back of the regulating plate.

[0011] Preferably, a set of collection covers is installed at the bottom of the two sets of splicing plates, and a guide arc groove is provided on the inner side of the lower end of the collection cover. A collection frame is installed in the middle of the lower end of the collection cover, and a collection bucket is rotatably installed at the bottom of the collection frame.

[0012] Preferably, the adjusting plate is equipped with limit frames at both ends, and two sets of support springs are provided inside the limit frames. An auxiliary handle is provided in the middle of the two sets of support springs, and a set of pressing plates is installed at the end of the auxiliary handle. The pressing plates are movably disposed inside the limit frames. A positioning tooth block is welded to the side of the pressing plate away from the auxiliary handle, and the positioning tooth block is movably inserted into the inside of the positioning tooth groove.

[0013] Preferably, the top of the support frame is equipped with several sets of support plates, and a double-layer mixing drum is installed on the top of the support plates. A mixing motor is fixedly installed on the top of the double-layer mixing drum. Two sets of spray pumps are provided on the top of the support plates, and the spray pumps are connected to the double-layer mixing drum through pipes. Two sets of support wheels are installed on both sides of the support frame near the double-layer mixing drum, and vertical steering wheels are fixedly installed on both sides of the support frame away from the support wheels by bolts. A controller is installed on the top of the support plate away from the double-layer mixing drum, and a solenoid valve is connected to the side of the spray pump away from the double-layer mixing drum through a pipe.

[0014] Preferably, the bottom of the solenoid valve is equipped with four sets of fixing posts, and a connection end is installed on the side of the solenoid valve near the spray pump. A flow divider is installed on the side of the solenoid valve away from the connection end, and four sets of connection ports are provided on the side of the flow divider away from the solenoid valve. The connection ports are connected to the fixed transmission pipe through flexible hoses.

[0015] Preferably, a spraying method for a road marking reflective layer spraying machine in rainy nights: S1. Use a remote control device to operate the controller, then adjust the position of the supporting frame through the controller, and set the overall movement path of the device on the remote control device. Then, use a spray pump to introduce the marking paint and reflective paint inside the double-layer mixing drum into the solenoid valve. Use the solenoid valve to control the opening and closing. After passing through the solenoid valve, the paint inside is evenly distributed by the distributor through the hose into the fixed transmission pipe, and then sprayed out from the H-shaped nozzle at the bottom to cover the road surface. S2. When it is necessary to fold or adjust the spraying structure to the other side, the servo motor is controlled by the controller. When powered on, it will drive the adjusting screw to rotate. During the rotation, the screw slider will move towards the switching switch using the threaded structure. During the movement, it will slide simultaneously through the limit shaft and the bottom strip slider. As the strip slider moves, it will pull the guide plate. At the same time, the sliding column will move along the arc frame under the pull. When the sliding column passes one side of the control switch, the squeeze switch will be opened. After opening, the electromagnet will generate an electrical circuit, which will create an attraction force to attract the sliding column and move it. With continuous movement, the sliding column will move to the middle area of ​​the two sets of electromagnets. At this time, the spraying structure will be directly under the supporting frame. S3. When it is necessary to change the orientation, continue to control the bar slider to move towards the switch and contact the button inside the switch. After the button is triggered, the switch will change the power circuit to another set of electromagnets and generate magnetic force. Then, the servo motor will be used to control the adjustment screw to rotate in the opposite direction, which will drive the screw slider to move towards the fixed bracket. Since the magnetic force of the other set of electromagnets will attract the sliding column, the sliding column will automatically move along the other set of arc frames during the movement. When the sliding column passes the other set of control switches, the current inside the electromagnet will be disconnected. After continuous pushing, the bar slider will reset and enter the inside of the straight frame again. S4. Before spraying, pull the two sets of auxiliary handles to separate the positioning tooth block from the positioning tooth groove. After separation, the position and range of the adjustment plate can be adjusted laterally along the C-shaped bracket by pushing and pulling. After releasing, the internal support spring will push the positioning tooth block to reset and be embedded in the inner side of the positioning tooth groove for locking. Then, grasp the adjustment knob to drive the adjustment screw to rotate. During the rotation, the threaded structure will drive the movable plate and the two sets of fixed transmission pipes to move up and down. By moving, the height of the H-type nozzle inside the collection hood can be changed. During the spraying process, the excess area is blocked by the guide arc groove of the collection hood and guided to the inner side of the collection frame for collection by the collection bucket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the coordination of an adjustable folding assembly and a guide plate, facilitates the folding of the painting mechanism into the inner side of the vehicle frame, avoiding the problem of occupying too much space and causing inconvenience in transportation. Simultaneously, the position of the painting mechanism can be changed through adjustment to adapt to different needs. A servo motor drives the adjusting screw to rotate. During rotation, the screw slider, under the action of the thread, drives the bottom strip slider and the guide plate to slide synchronously along the inner channel. As the guide plate moves, it pulls the C-shaped bracket assembly towards the vehicle frame, and the sliding column slides stably along the arc frame into the middle area of ​​the connecting plate. With the help of control switches, a solenoid, and a switching switch, the direction of the sliding column's movement can be flexibly adjusted. Pushing the guide plate and C-shaped bracket outwards switches the orientation of the painting mechanism. The adjustable folding assembly allows for flexible adjustment to meet different painting requirements.

[0017] This invention, through the combination of an adjustable collection component and a C-shaped bracket, facilitates the limitation of the spraying area by adjusting the height of the nozzle in conjunction with the collection hood, ensuring a flat spraying surface. This reduces the need for ground-based limiting stickers to prevent uneven spraying areas. An adjustable plate provides an installation position for the outer structure, and adjusting the knob controls the rotation of the adjusting screw, which in turn moves the movable plate and fixed transmission pipe up and down along the adjustable plate. Adjustment limits the spraying area. The edge of the guide arc groove cuts the sprayed material, and excess reflective paint flows along the guide arc groove into the collection tank, where it is collected by the central collection bucket, thus achieving resource recycling.

A straight frame 201 is welded to the end between the two sets of arc-shaped frames 200. A control switch 202 is spliced ​​and installed at the end of the arc-shaped frame 200 away from the straight frame 201, and a magnet 203 is fixedly installed at the end of the control switch 202 away from the arc-shaped frame 200. A connecting plate 309 is welded and installed at the end of the magnet 203 away from the control switch 202, and a switch 205 is welded and installed at the end of the connecting plate 309 away from the magnet 203. A button is provided in the groove of the switch 205 near the side of the arc frame 200. A strip slider 300 is slidably provided on the inner side of the straight frame 201. A guide plate 401 is rotatably provided on the top of the strip slider 300. A lead screw slider 307 is rotatably provided on the top of the guide plate 401. An adjusting lead screw 303 is rotatably provided in the middle of the lead screw slider 307. A sliding column 404 is fixedly installed at the bottom of the guide plate 401 away from the strip slider 300. The sliding column 404 is slidably provided on the inner side of the arc frame 200.

[0022] Several sets of connecting wires 204 are connected between the electromagnet 203 and the switch 205, and two sets of wires 206 are installed at the end of the switch 205 away from the connecting wires 204.

[0023] Using the above solution: the supporting frame 100 can provide the installation position for the overall structure of the top and inner side; the arc frame 200 and the straight frame 201 can be spliced ​​together to restrict the sliding structure on the inner side; the two sets of arc frames 200 face opposite directions, and the straight frame 201 is located in the middle area of ​​the arc frame 200; the sliding groove of the overall structure is a three-pronged structure; the outer sides of the control switch 202, the electromagnet 203, and the switching switch 205 are all non-magnetic metals and are connected by welding; when the sliding column 404 slides and presses against the control switch 202, the circuit is triggered; the electromagnet 203 attracts and guides the metal sliding column 404. The guide or direction can change the orientation of the C-shaped bracket 400. The strip slider 300 can slide and adjust between the straight frame 201 and the connecting plate 309. The lead screw slider 307 can slide laterally under the action of the adjusting lead screw 303, thereby transmitting the force of lateral movement to drive the bottom structure to adjust synchronously. The sliding column 404 can slide stably along the inner side of the arc frame 200, thereby adjusting the orientation of the C-shaped bracket 400. The connecting wire 204 is used to connect the electromagnet 203 to the switch 205. After connection, the current direction can be adjusted by using the switch 205. At the same time, the wire 206 can be used to connect to the external controller 104.

[0024] like Figure 3 ,and Figure 4 As shown, a servo motor 302 is fixedly installed at the input end of the adjusting screw 303, and a fixing plate 301 is fixedly installed on the side of the servo motor 302 close to the adjusting screw 303.

The welding frame 306 is welded to the inner side of the upper end of the carrier frame 100. Two sets of limit guide rods 304 are fixedly installed between the fixing bracket 305 and the fixing plate 301. The screw slider 307 is slidably installed on the outside of the limit guide rods 304. A limit shaft 308 is welded between the screw slider 307 and the strip slider 300. The guide plate 401 is rotatably installed on the outside of the limit shaft 308.

[0025] A C-shaped bracket 400 is installed at one end of the guide plate 401 away from the limiting shaft 308, and a reinforcing corner seat 402 is welded to the inner side of the C-shaped bracket 400 and the guide plate 401. Several sets of positioning tooth grooves 403 are opened on the side of the C-shaped bracket 400 away from the middle, and an adjustment and collection component 002 is slidably provided on the outer side of the end of the C-shaped bracket 400.

[0026] The above scheme is adopted: the servo motor 302 can provide rotational kinetic energy for the adjusting screw 303. The adjusting screw 303 can be restricted by the fixed plate 301 and the fixed bracket 305, which can help the adjusting screw 303 rotate stably. The welding frame 306 can connect the fixed bracket 305 to the carrier frame 100 to maintain the stability of the structure. The limiting guide rod 304 is used to limit the screw slider 307 to maintain the stability of the adjustment sliding. The limiting shaft 308 can restrict the outer guide plate 401. The cylinder assisted rotation can adjust the orientation of the C-shaped bracket 400.

[0027] like Figures 6-8 As shown, the regulating collection assembly 002 includes an regulating plate 501, and an regulating screw 502 is rotatably mounted on the top of the regulating plate 501. An regulating knob 503 is mounted on the top of the regulating screw 502, and a movable plate 504 is rotatably mounted on the outer side of the regulating screw 502. A fixed transmission pipe 505 is fixedly mounted on the inner side of both ends of the movable plate 504, and an H-shaped nozzle 500 is mounted on the bottom of the fixed transmission pipe 505. A splicing plate 601 is spliced ​​and mounted on the front and back of the regulating plate 501.

[0028] A collection cover 600 is installed at the bottom of the two sets of splicing plates 601, and a guide arc groove 602 is provided on the inner side of the lower end of the collection cover 600. A central frame 603 is installed in the middle of the lower end of the collection cover 600, and a collection bucket 604 is rotatably installed at the bottom of the central frame 603.

[0029] Limit frames 701 are installed at both ends of the adjusting plate 501, and two sets of support springs 702 are provided inside the limit frames 701. An auxiliary handle 704 is provided in the middle of the two sets of support springs 702, and a pressing plate 703 is installed at the end of the auxiliary handle 704. The pressing plate 703 is movably disposed inside the limit frame 701. A positioning tooth block 700 is welded on the side of the pressing plate 703 away from the auxiliary handle 704, and the positioning tooth block 700 is movably inserted into the inside of the positioning tooth groove 403.

[0030] Using the above scheme: the adjusting plate 501 provides splicing constraints for the outer structure; the adjusting knob 503 drives the adjusting screw 502 to rotate, which in turn drives the movable plate 504 to move up and down stably; the fixed transmission pipe 505 can transport the internal paint; the H-type nozzle 500 can spray the internal reflective paint into a strip shape; the splicing plate 601 can be spliced ​​with the adjusting plate 501; and the collection cover 600 can cut the sprayed reflective paint through the guide arc groove 602 at the bottom, and excess paint will be... Following the guide arc groove 602 into the inner side of the concentrating frame 603, the paint can be finally collected using the collection bucket 604. The inner walls of the guide arc groove 602, the concentrating frame 603, and the collection bucket 604 all have a nano-coating, which can prevent reflective paint from adhering, making it easy to pour out and preventing sticking. The limiting frame 701 can provide restraint for the inner structure. The support spring 702 can push the extrusion plate 703 and the positioning tooth block 700 to embed into the inner side of the positioning tooth groove 403. The auxiliary handle 704 can provide a grip for the user and facilitate adjustment by pulling.

[0031] like Figure 1 , Figure 2 and Figure 9 As shown, several sets of support plates 106 are installed on the top of the support frame 100, and a double-layer mixing drum 101 is installed on the top of the support plate 106. A mixing motor 102 is fixedly installed on the top of the double-layer mixing drum 101. Two sets of spray pumps 103 are provided on the top of the support plate 106, and the spray pumps 103 are connected to the double-layer mixing drum 101 through pipes. Two sets of support wheels 107 are installed on both sides of the support frame 100 near the double-layer mixing drum 101, and vertical steering wheels 105 are fixedly installed on both sides of the support frame 100 away from the support wheels 107 by bolts. A controller 104 is installed on the top of the support plate 106 away from the double-layer mixing drum 101. A solenoid valve 800 is connected to the side of the spray pump 103 away from the double-layer mixing drum 101 through a pipe.

[0032] Four sets of fixing posts 801 are installed at the bottom of the solenoid valve 800, and a connection end 802 is installed on the side of the solenoid valve 800 near the spray pump 103. A flow divider 803 is installed on the side of the solenoid valve 800 away from the connection end 802, and four sets of connection ports 804 are provided on the side of the flow divider 803 away from the solenoid valve 800. The connection ports 804 are connected to the fixed transmission pipe 505 through flexible hoses.

[0033] Using the above scheme: the support plate 106 can provide support for the overall structure at the top, different coatings are stored inside the double-layer mixing drum 101, and the mixing motor 102 at the top can drive the mixing structure inside the double-layer mixing drum 101 to rotate and mix the coatings. The spray pump 103 can transfer the coatings from the double-layer mixing drum 101, and the liquid flow switch can be controlled by the solenoid valve 800. The distributor 803 can distribute the coatings to different spraying sides to meet different needs.

[0034] Working principle and usage process of this invention: The controller 104 is operated by a remote control device, and the position of the support frame 100 is adjusted by the controller 104. The overall movement path of the device is set on the remote control device. Then, the marking paint and reflective paint inside the double-layer mixing drum 101 are introduced into the solenoid valve 800 by the spray pump 103. The solenoid valve 800 is used to control the opening and closing. After passing through the solenoid valve 800, the paint inside is evenly distributed by the distributor 803 and introduced into the fixed transmission pipe 505 through the hose. It is then sprayed out from the H-shaped nozzle 500 at the bottom to cover the road surface. When the spraying structure needs to be folded or adjusted to the other side, the servo motor 302 is controlled by the controller 104. When powered on, it will drive the adjusting screw 303 to rotate. During the rotation, the screw slider 307 will move towards the switching switch 205 using the threaded structure. During the movement, it will slide simultaneously through the limit shaft 308 and the bottom strip slider 300. During the movement of the strip slider 300, it will pull the guide plate 401. At the same time, the sliding column 404 will move along the arc frame 200 under the pull. When the sliding column 404 passes one side of the control switch 202, the squeeze switch will be opened. After the switch is opened, the electromagnet 203 will generate an electrical circuit, which will attract the sliding column 404 and move it. With continuous movement, the sliding column 404 will move to the middle area of ​​the two sets of electromagnets 203. At this time, the spraying structure will be directly under the support frame 100. When the orientation needs to be changed, continue to control the strip slider 300 to move towards the switch 205 and contact the button inside the switch 205. After the button is triggered, the switch 205 will change the power circuit to another set of electromagnets 203 and generate magnetic force. Then, the servo motor 302 will control the adjustment screw 303 to rotate in the opposite direction, which will drive the screw slider 307 to move towards the fixed bracket 305. Since the magnetic force of the other set of electromagnets 203 will attract the sliding column 404, the sliding column 404 will automatically move along the other set of arc frames 200 during the movement. When the sliding column 404 passes the other set of control switches 202, the current inside the electromagnet 203 will be disconnected. After continuous pushing, the strip slider 300 will reset and enter the inner side of the straight frame 201 again. Before spraying, pull the two sets of auxiliary handles 704 to separate the positioning tooth block 700 from the positioning tooth groove 403. After separation, the position and range of the adjustment plate 501 can be adjusted laterally along the C-shaped bracket 400 by pushing and pulling. After releasing, the internal support spring 702 will push the positioning tooth block 700 to reset and be embedded in the inner side of the positioning tooth groove 403 for locking. Then, grasp the adjustment knob 503 to drive the adjustment screw 502 to rotate. During the rotation, the threaded structure will drive the movable plate 504 and the two sets of fixed transmission pipes 505 to move up and down. By moving, the height of the H-type nozzle 500 inside the collection cover 600 can be changed. During the spraying process, the excess area is blocked by the guide arc groove 602 of the collection cover 600 and guided to the inner side of the collection frame 603 for collection by the collection bucket 604.

10. A spraying method for a road marking reflective layer spraying machine according to any one of claims 1-9, characterized in that: S1. Use a remote control device to operate the controller, then adjust the position of the supporting frame through the controller, and set the overall movement path of the device on the remote control device. Then, use a spray pump to introduce the marking paint and reflective paint inside the double-layer mixing drum into the solenoid valve. Use the solenoid valve to control the opening and closing. After passing through the solenoid valve, the paint inside is evenly distributed by the distributor through the hose into the fixed transmission pipe, and then sprayed out from the H-shaped nozzle at the bottom to cover the road surface. S2. When it is necessary to fold or adjust the spraying structure to the other side, the servo motor is controlled by the controller. When powered on, it will drive the adjusting screw to rotate. During the rotation, the screw slider will move towards the switching switch using the threaded structure. During the movement, it will slide simultaneously through the limit shaft and the bottom strip slider. As the strip slider moves, it will pull the guide plate. At the same time, the sliding column will move along the arc frame under the pull. When the sliding column passes one side of the control switch, the squeeze switch will be opened. After opening, the electromagnet will generate an electrical circuit, which will create an attraction force to attract the sliding column and move it. With continuous movement, the sliding column will move to the middle area of ​​the two sets of electromagnets. At this time, the spraying structure will be directly under the supporting frame. S3. When it is necessary to change the orientation, continue to control the bar slider to move towards the switch and contact the button inside the switch. After the button is triggered, the switch will change the power circuit to another set of electromagnets and generate magnetic force. Then, the servo motor will be used to control the adjustment screw to rotate in the opposite direction, which will drive the screw slider to move towards the fixed bracket. Since the magnetic force of the other set of electromagnets will attract the sliding column, the sliding column will automatically move along the other set of arc frames during the movement. When the sliding column passes the other set of control switches, the current inside the electromagnet will be disconnected. After continuous pushing, the bar slider will reset and enter the inside of the straight frame again. S4. Before spraying, pull the two sets of auxiliary handles to separate the positioning tooth block from the positioning tooth groove. After separation, the position and range of the adjustment plate can be adjusted laterally along the C-shaped bracket by pushing and pulling. After releasing, the internal support spring will push the positioning tooth block to reset and be embedded in the inner side of the positioning tooth groove for locking. Then, grasp the adjustment knob to drive the adjustment screw to rotate. During the rotation, the threaded structure will drive the movable plate and the two sets of fixed transmission pipes to move up and down. By moving, the height of the H-type nozzle inside the collection hood can be changed. During the spraying process, the excess area is blocked by the guide arc groove of the collection hood and guided to the inner side of the collection frame for collection by the collection bucket.
