Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to an automatic printing device for tactile paving signs. Background Technology

[0002] Tactile paving is a road facility specifically designed to assist blind people in walking. Tactile paving is generally paved with two types of bricks: one type is guide bricks, which guide blind people forward with confidence; this is called tactile paving for movement. The other type is indicator bricks with dots, which indicate obstacles ahead and require a turn; this is called indicator tactile paving. Tactile paving marking printing equipment is suitable for sidewalks with permeable concrete structures. The permeable concrete is poured integrally in the original tactile paving brick location, and raised markings are printed on top.

[0003] In the existing technology, tactile paving marking printing equipment can generally only print one type of marking, such as strip tactile paving markings. When it is necessary to print circular markings, it is necessary to change the circular marking printing equipment or have the staff manually change the circular marking template, which is troublesome, time-consuming, and inefficient.

[0017] The beneficial effects of this invention are as follows:

[0018] In use, the invention involves activating two second forward and reverse motors to drive two support rods and two support plates to rotate in opposite directions. Activating two first electric push rods pulls two locking blocks out of their corresponding mounting blocks. Activating the first hydraulic rod pulls the mounting seat away from the outer surface of the strip printing template. Activating the first forward and reverse motors again drives the lead screw to rotate, moving two moving plates and two U-shaped push plates, thus pushing the circular printing template. This causes a repulsive force to gradually form between the two magnets, pushing the strip printing template to one side. When the circular printing template moves to below the mounting seat, the first forward and reverse motors automatically reverse a certain number of turns and then stop, moving the moving plates and U-shaped push plates back. Activating the first hydraulic rods again pushes the mounting seat onto the circular printing template, and activating the two electric push rods again causes the locking blocks to engage inside the mounting blocks, thereby installing the circular printing template.

[0019] In use, the dual-axis motor is started to drive the two first rotating rods and two drive wheels to rotate, which in turn drives the rubber track to rotate, thus moving the entire equipment forward. The laser emitter is activated to emit a laser beam, forming a clear red line on the tactile paving to indicate the position and direction of the print, thereby determining the route and distance to move forward. The rubber track provides a larger contact area and better grip, reducing the bumps and swaying of the equipment during operation, and also reducing damage to the road.

[0020] During use, the tilt sensor detects the road surface tilt in real time. When the equipment tilts, the control system activates the corresponding second hydraulic rod, which pushes the reinforcing plate on the tilted side upward. The reinforcing rod lifts the corresponding reinforcing block, thereby lifting the tilted side of the machine body upward and keeping the machine body balanced, thus achieving the effect of automatic leveling.

[0021] In use, the servo motor is started, driving the rotating shaft to rotate, which in turn drives the first and second stirring rods to rotate, mixing the material from top to bottom to improve the uniformity of the mixing, thereby ensuring the consistency and stability of the printing quality. After the mixing is completed, the first hydraulic rod is started to push the lifting plate downward, while simultaneously pulling the folding tube open and pushing the mounting base and the strip printing template downward through the moving hole. Then, the solenoid valve is opened, allowing the material to enter the connecting tube and the folding tube in sequence, and then enter the interior of the strip printing template through the feeding tube and the feeding hole. The vibrator is then started to vibrate and compact the material to form the final shape. Attached Figure Description

The machine body 1 includes a base plate 101. The movable component 5 and the base plate 101 are fixedly connected. A reinforcing plate 11 is fixedly installed inside the machine body 1. A feeding and mixing component 4 is supported on the upper part of the reinforcing plate 11. The feeding and mixing component 4 includes a feeding tank 401. A connecting pipe 404 is provided at the bottom of the feeding tank 401. Multiple folded pipes 407 are provided circumferentially at the lower part of the connecting pipe 404. The folded pipes 407 pass through the reinforcing plate 11. A lifting component 6 is provided at the bottom of the reinforcing plate 11. A printing component 7 is slidably connected to the lifting component 6. The printing component 7 includes a mounting base 701. The mounting base 701 has multiple discharge holes 702 corresponding to the folded pipes 407. A mold changing component 8 is detachably provided at the lower part of the mounting base 701. The mold changing component 8 includes a printing template 805. The printing template 805 has sealing holes that cooperate with the discharge holes 702. The lifting assembly 6, printing assembly 7, and mold changing assembly 8 work together to ensure stable operation and good printing results. The moving assembly 5 can drive the machine body 1 to move in different working areas, making overall operation convenient and effective. Two printing templates 805 are provided, one with a strip-shaped opening and the other with a circular opening, allowing for flexible mold changing according to printing needs before printing, making operation convenient.

[0040] In a preferred embodiment, the mobile component 5 includes a mobile base 501, which is fixed to the underside of the base plate 101. The mobile base 501 has mounting slots 502 on its front and rear sides. A fixing plate 503 is mounted on the inner wall of one of the mounting slots 502. A dual-axis motor 504 is mounted on the fixing plate 503, and first rotating rods 506 are connected to both sides of the dual-axis motor 504. A second rotating rod 509 passes through the inner wall of the other mounting slot 502. Drive wheels 507 are mounted at both ends of the first and second rotating rods 506. A rubber track 508 meshes between the two drive wheels 507 on the same side. A laser emitter 505 is located at the bottom of the fixing plate 503. The battery 10 powers other equipment. The control system 2 is started by turning on the switch. Through the data interface of the control system 2, two-dimensional drawings can be transmitted to the control system 2 via data transfer. Operators can select the required drawings through the programs and settings within the control system 2 and view them through the import view panel 3. By starting the dual-axis motor 504, the two first rotating rods 506 are driven to rotate, which in turn drives the two drive wheels 507 to rotate, further driving the rubber track 508 to rotate, thereby moving the entire equipment forward. The laser emitter 505 is activated to form a clear red line on the tactile paving to indicate the printing position and direction, thus determining the forward route and distance. The rubber track 508 can reduce the bumps and swaying of the equipment during operation, thereby improving the stability and accuracy of printing.

[0041] In a preferred embodiment, the mold changing assembly 8 includes two parallel movable plates 803, a U-shaped push plate 804 fixedly mounted on the inner side of the movable plates 803, two printing templates 805, which are arranged between the two opposite U-shaped push plates 804, a lead screw 802 and a support rod 809 passing through the movable plates 803 in parallel, and a connecting groove 807 on the opposite side of the two printing templates 805, with a magnetic strip 808 inside the connecting groove 807;

[0042] Two mounting blocks 806 are provided on the upper side of the printing template 805. Each mounting block 806 has an alignment port 811. A bracket 704 is provided on both sides of the mounting base 701. A first electric push rod 705 is located inside the bracket 704. A locking block 706 is connected to the end of the first electric push rod 705, and the locking block 706 is inserted into the alignment port 811. A vibrator 703 is located in the center of the top of the mounting base 701. Multiple fixed cylinders 708 are provided outside the vibrator 703. A movable cylinder 709 is supported inside the fixed cylinder 708 by a first spring 710, and the movable cylinder 709 passes through the fixed cylinder 708. A limiting rod 707 improves the stability of the movement of the mounting base 701. With the cooperation of the fixed cylinders 708, the movable cylinders 709, and the springs 710, the mounting base 701 and the lifting plate 602 are elastically connected.

[0043] In a preferred embodiment, a control system 2 is connected to the machine body 1. The lower side of the control system 2 has an observation window 102 and a maintenance door 103, which is hinged to the machine body 1. A visual interactive panel 3 is located on one side of the control system 2. A connecting plate 9 is located on the upper side of the base plate 101, and the connecting plate 9 is fixed to the inner wall of the machine body 1. A battery 10 is connected to the connecting plate 9. A fixing hole 12 is located at the top of the machine body 1, and the feeding tank 401 is fixed inside the fixing hole 12. The overall structure is compact. The visual interactive panel 3 allows for direct observation of the document's status and effect. The observation window 102 allows staff to easily see whether the components are moving erratically during mold changing and printing. The maintenance door 103 facilitates opening the machine body 1 for operation when maintenance is required.

[0044] In a preferred embodiment, a servo motor 402 is provided at the top of the feeding tank 401, and a cover plate is hinged to the feeding tank 401. The cover plate can rotate around the servo motor 402 axially and is used for opening and closing the feeding tank 401. A rotating shaft 406 is connected to the lower part of the servo motor 402. The rotating shaft 406 passes through the feeding tank 401 and the connecting pipe 404. A plurality of first stirring rods 403 are arranged axially parallel on the outer side wall of the rotating shaft 406. A fixing frame 409 is sleeved at the bottom of the rotating shaft 406. A plurality of second stirring rods 410 are arranged circumferentially on the upper side of the fixing frame 409.

[0045] A solenoid valve 405 is provided on the connecting pipe 404 to control its opening and closing. A feeding pipe 408 is connected to the bottom of the folding pipe 407. The lifting assembly 6 includes a first hydraulic rod 601, with a lifting plate 602 at its end. The feeding pipe 408 passes through the lifting plate 602. The lifting plate 602 and the reinforcing plate 11 are connected by multiple first multi-section telescopic rods 603. The feeding pipe 408 is positioned directly opposite the feeding hole 702. Multiple limiting rods 707 are provided on the mounting base 701, passing through the lifting plate 602. By starting the servo motor 402, the rotating shaft 406 is driven to rotate, which in turn drives the first stirring rod 403 and the second stirring rod 410 to rotate. This allows for simultaneous mixing of the material in the feeding tank 401, improving mixing uniformity and printing quality. The folded tube 407 and the feeding tube 408 facilitate the delivery of materials to the printing template 805. The first hydraulic rod 601 facilitates the pulling plate 602 to move up and down. The vibrator 703 vibrates and compacts the material, which is convenient for forming.

[0046] In a preferred embodiment, a tilt sensor 14 is detachably mounted on the bottom of the movable base 501. Adjustment grooves 510 are located on both sides of the movable base 501, and a leveling assembly 15 is installed within each adjustment groove 510. The leveling assembly 15 includes a reinforcing plate 1502, which is mounted within the adjustment groove 510 via a reinforcing rod 1503. A reinforcing block 1504 is fitted onto the reinforcing rod 1503. A second hydraulic rod 1501 is located at the bottom center of the reinforcing plate 1502, and second multi-section telescopic rods 1505 are located on both sides of the second hydraulic rod 1501. The tilt sensor 14 detects the road surface tilt in real time. When the equipment tilts, the tilt sensor 14 transmits the detected tilt information to the control system 2. The control system 2 then activates the corresponding second hydraulic rod 1501, pushing the reinforcing plate 1502 on the downward tilting side upward. The reinforcing rod 1503 then lifts the corresponding reinforcing block 1504, thereby lifting the downward tilting side of the machine body 1 upward, maintaining the machine body 1's balance, and achieving an automatic leveling effect. The bottoms of the two second hydraulic rods 1501 are fixedly installed at the center of the bottom surface inside the two adjustment slots 510. The bottom surfaces of the two adjustment slots 510 near both sides are fixedly installed with second multi-section telescopic rods 1505. The tops of each pair of second multi-section telescopic rods 1505 are fixedly installed at the bottom of the two reinforcing plates 1502, so as to improve the stability of the movement of the lifting plate 602 under the action of the first multi-section telescopic rod 603, and improve the stability of the movement of the reinforcing plate 1502 under the action of the second multi-section telescopic rods 1505.

[0047] In a preferred embodiment, a movable hole 13 is provided in the middle of the base plate 101. The movable hole 13 has symmetrically arranged recessed grooves 17 along the traveling direction of the movable component 5. A support component 16 is detachably installed within the recessed grooves 17. The support component 16 includes a support plate 1603, with a support rotating rod 1602 passing through it. A second forward / reverse motor 1601 is provided at the end of the support rotating rod 1602. The support plate 1603 supports the printing template 805. By activating the two second forward / reverse motors 1601, the two support rotating rods 1602 rotate in opposite directions, further rotating the two support plates 1603 into the movable hole 13, preventing the printing template 805 from falling out of the movable hole 13 when it is subsequently replaced.

[0048] In a preferred embodiment, the connecting pipe 404 is fixed to the top of the reinforcing plate 11. A first forward / reverse motor 801 is located at the end of the lead screw 802. Both sides of the support rod 809 are fixed to the inner wall of the machine body 1. The end of the lead screw 802 furthest from the first forward / reverse motor 801 is rotatably mounted on the inner wall of the machine body 1. The bottom of the first forward / reverse motor 801 is fixedly installed inside the machine body 1 near the rear surface. One end of the lead screw 802 is movably embedded in one side of the inner wall of the machine body 1. Support rods 809 are fixedly installed on the inner walls of both sides of the machine body 1 near the front surface. One end of the support rod 809 movably passes through the two moving plates 803 to the outer surface and is engaged with the mounting block 806 via a locking block 706. This allows for the installation and fixing of the printing template 805. The support rod 809 limits the movement of the moving plates 803, facilitating their normal movement.

[0049] like Figure 11-13 In the preferred embodiment, parallel grooves 105 are respectively provided on the bottom plates 101 on both sides of the moving hole 13. A limiting component 18 is detachably provided on one side of the groove 105. The limiting component 18 includes a second electric push rod 1801. A slide plate 1802 is provided at the end of the second electric push rod 1801. A protrusion 1803 is provided at the bottom of the slide plate 1802. The protrusion 1803 is located in the groove 105. The slide plate 1802 is used to ensure that the printing template 805 moves smoothly in the moving hole 13. The moving hole 13 facilitates the moving plate 803 to push the printing template 805 to move for mold changing. Then, in the middle of the moving hole 13, it ensures that the printing component 7 above can accurately grasp the printing template 805. In order to ensure that the printing template 805 moves only in the axial direction, the slide plate 1802 plays a limiting role, reducing the moving width of the moving hole 13 and ensuring safe and stable movement.

[0050] like Figure 14-15In a preferred embodiment, the upper part of the support assembly 16 is detachably provided with a positioning assembly 19. A through groove 1604 is provided through the upper side of the support plate 1603. A recessed groove 1605 is provided on one side of the through groove 1604, and threaded holes 1606 are provided on both sides of the recessed groove 1605. The positioning assembly 19 includes a locking head 1901. A driving inclined surface 1902 is symmetrically provided on one side of the locking head 1901, and the driving inclined surface 1902 abuts against the side wall of the through groove 1604. The other side of the locking head 1901... A limiting plate 1903 is provided on the side, with a mounting hole 1906 in the middle of the limiting plate 1903. A second spring 1905 is fixed in the mounting hole 1906 and abuts against a sealing plate 1904. A screw 20 passes through the sealing plate 1904, with one side of the screw 20 located in a threaded hole 1606. A bayonet 810 passes through the middle of the printing template 805. A relief slope 104 is provided on the lower part of the base plate 101 near the support component 16. This structure ensures that after the mold change is completed, the support component 16 provides relief, guaranteeing that the printing template 805 can contact the ground under the driving action of the lifting component 6 and the printing component 7 to complete the printing. At the same time, the positioning component 19 ensures accurate alignment during the mold change process, avoiding the problem of low gripping efficiency of the printing component 7.

The servo motor 402, solenoid valve 405, dual-axis motor 504, laser emitter 505, first hydraulic rod 601, vibrator 703, electric actuator 705, first forward / reverse motor 801, tilt sensor 14, second hydraulic rod 1501, second forward / reverse motor 1601, control system 2, import image viewing panel 3, and battery 10 are electrically connected. Battery 10 powers other devices. Turning on the control system 2 starts it up. Through the data interface of control system 2, DXF drawings can be transmitted to control system 2 via data transfer. Staff can select the required drawings through the programs and settings within the control system 2, and view the drawings via the import view panel 3. Printing ink is poured into the feeding tank 401 through its arc-shaped inlet. The control system 2 activates the servo motor 402, which in turn drives the rotating shaft 406 to rotate. This, in turn, drives the first stirring rod 403 and the second stirring rod 410 to rotate. The second stirring rod 410, being smaller and embedded in the feeding tank 401 near the bottom, simultaneously mixes the material in the feeding tank 401 from top to bottom, improving mixing uniformity and ensuring thorough mixing of pigments, fillers, and solvents. This prevents particle accumulation or sedimentation, thus guaranteeing consistent printing quality. After mixing, the first hydraulic rod 601 is activated via the operation button on control system 2, pushing the lifting plate 602 downward and simultaneously pulling the folded tube 407 out. With the cooperation of the fixed cylinder 708, the movable cylinder 709, the spring 710, and the limit rod 707, the mounting base 701 is pushed downward, causing the strip printing template 805 to move downward through the moving hole 13. When the strip printing template 805 contacts the ground, the first hydraulic rod 601 automatically stops, and then the solenoid valve 405 is activated to open, allowing the mixed material to enter the connecting pipe 404 and then flow into the four folded tubes 407. The four discharge pipes 408 are located above the four discharge holes 702, and the material flows along the folded tubes 407 into the discharge pipes 408. Next, the material enters the strip printing template 805 through the four feeding holes 702. Then, the vibrator 703 is activated, which drives the mounting base 701 to vibrate, further transmitting the vibration force to the printing template 805 and the material inside, compacting the material and preventing air bubbles or gaps that could affect the printing effect. After the material is compacted and formed in the printing template 805, the first hydraulic rod 601 is activated again, pulling the lifting plate 602, the mounting base 701, and the printing template 805 upwards. Driven by the moving component 5, it moves to the next printing location. When it is necessary to change the printing template 805, two second forward and reverse motors 1601 are activated simultaneously, with the outputs of the two second forward and reverse motors 1601 rotating in opposite directions.The two support rods 1602 rotate in opposite directions, further rotating the two support plates 1603 into the moving holes 13. At this point, the top of the support plate 1603 contacts the bottom of the strip printing template 805. Then, the two electric actuators 705 are activated simultaneously, pulling the two locking blocks 706 out of the corresponding mounting blocks 806. At this point, the strip printing template 805 loses its fixation and falls onto the two support plates 1603. The first hydraulic rod 601 is activated again, continuing to pull the mounting base 701 upward, causing the mounting base 701 to leave the outer surface of the strip printing template 805. When the first hydraulic rod 601 can no longer pull upward, it will automatically stop. Then, the first forward and reverse motor 801 is activated again, driving the lead screw 802 to rotate, which in turn drives the two moving plates 806. 3. Move to one side, then move the two U-shaped push plates 804, further moving the circular printing template 805 on the support plate 1603 towards the strip printing template 805. The two magnets 808 have the same magnetic poles. As the two magnets 808 get closer, a repulsive force gradually forms between them. With the movement of the circular printing template 805 and the repulsive force between the magnets 808, the strip printing template 805 is pushed to one side. When the circular printing template 805 moves to below the mounting base 701, the strip printing template 805 moves from the moving hole 13 to the bottom of the machine body 1 near the other side. At the same time, the first forward and reverse motor 801 automatically reverses a certain number of revolutions and then stops, driving the moving plate 803 and the U-shaped push plate 804 to move back. One U-shaped pusher plate 804 moves away from the circular printing template 805, while the other U-shaped pusher plate 804 moves to the strip printing template 805. By restarting the first hydraulic rod 601, the mounting base 701 is pushed onto the circular printing template 805. At this point, the four circular feed ports on the circular printing template 805 are aligned with the centers of the four discharge holes 702. Then, the two electric pushers 705 are restarted, causing the locking block 706 to engage with the mounting block 806 on the circular printing template 805, thus installing the circular printing template 805. Next, the two second forward and reverse motors 1601 are restarted, causing the two support plates 1603 to rotate downwards and open, allowing circular markings to be printed through the circular printing template 805 without the need for manual operation. Manual replacement solves the problem that traditional tactile paving marking printing equipment can generally only print one shape of mark. When printing round marks, workers have to manually change the round mark template, which is cumbersome, time-consuming, and inefficient. Starting the dual-axis motor 504 drives two first rotating rods 506 through their two outputs, which in turn drives two drive wheels 507, further rotating the rubber track 508, thus moving the entire equipment forward. A road surface reference point is pre-set, and then the laser emitter 505 is activated, emitting a laser beam. Aligning the laser beam with the road surface reference point creates a clear red line on the tactile paving, indicating the printing position and direction, thereby determining the forward path and distance.The rubber track 508 provides a larger contact area and better grip, adapting to different road conditions and reducing bumps and swaying during operation, thereby improving printing stability and accuracy. The rubber track 508 also distributes the equipment's weight evenly across a larger contact area, reducing pressure concentration on the road surface, minimizing damage and extending road lifespan. During forward movement, the tilt sensor 14 detects road tilt in real time. When unevenness causes the equipment to tilt, the tilt sensor 14 transmits the detected tilt information to the control system 2. The control system 2 then activates the corresponding second hydraulic rod 1501, pushing the reinforcing plate 1502 on the downward tilting side upwards. The reinforcing rod 1503 then lifts the corresponding reinforcing block 1504, thus lifting the downward tilting side of the machine body 1 upwards, maintaining balance and achieving automatic leveling.
