Technical Field

[0001] The present invention relates to the technical field of curbstone processing, and particularly relates to a production line for luminous curbstones. Background Art

[0002] A curbstone is a marker stone set between a road surface and other structures. Curbstones are usually required between the median strip and the road surface of urban roads, and between the sidewalk and the road surface. Some existing curbstones can emit light to identify the position of the curbstone at night, serving the purposes of lighting and enhancing the beauty. For example, the Chinese patent with the authorization announcement number CN218621926U and the authorization announcement date of March 14, 2023, discloses "A Luminous Curbstone", and after the lamp slot is lit, the light can pass through the transparent lamp tube and the light-transmitting slot.

[0003] When producing the above-mentioned curbstone, it is necessary to combine the curbstone body, the lamp tube and the fixing sleeve together, and reserve parts such as the light-transmitting slot, the weight-reducing hole, and the installation slot. At this time, it is necessary to design the forming mold, the concrete cloth part, the demolding part, etc. to meet the production and processing of the luminous curbstone. Summary of the Invention

[0004] The purpose of the present invention is to provide a production line for luminous curbstones, which has the function of realizing the combination of the curbstone body, the lamp tube and the fixing sleeve for processing luminous curbstones.

[0005] The above technical object of the present invention is achieved by the following technical solutions: A production line for luminous curb stones includes a forming mold, a concrete mixer, a concrete distribution unit that conveys concrete into the forming mold and compacts it, a steam curing chamber for steam curing the concrete in the forming mold, a demolding unit for removing the forming mold, and a grinding machine for grinding the curb stone body after demolding. The forming mold includes a main template with a cross-section in a "U" shape, a square frame fixedly arranged on the periphery of the main template, two side templates located on both sides of the main template and detachably arranged with the square frame, and an air inflation assembly. A first protrusion corresponding to the light-transmitting groove of the luminous curb stone is arranged at the bottom of the main template. Second protrusions corresponding to the installation grooves of the luminous curb stone are arranged on both sides of the side templates. A limiting portion embedded in the end of the fixing sleeve of the luminous curb stone is arranged on the second protrusion. The lamp tube of the luminous curb stone is placed on the first protrusion, and two fixing sleeves are installed on the limiting portions of the two side templates. A weight-reducing hole corresponding to the luminous curb stone and a through hole in an "8" shape are arranged on the side template. After the air inflation assembly is inflated, it fills the space corresponding to the through holes of the two side templates and both ends penetrate through the through holes. The concrete distribution unit includes a distribution device that conveys concrete into the forming mold and compacts it, a mold input device that conveys the forming mold to the distribution device, a mold output device that receives the forming mold output from the distribution device, and a first palletizing machine that palletizes the forming mold on the mold output device. The demolding unit includes a second palletizing machine, a conveying device that receives the forming mold from the second palletizing machine, a lifting device that lifts the forming mold to remove the side template and the air inflation assembly, a mold flipping device that flips the forming mold 180 degrees, a vibration demolding device that separates the main template of the forming mold and the curb stone body through vibration, and a lifting device that hoists the forming mold.

[0006] By adopting the above technical solutions, (1) in the forming mold, the first protruding part of the main template of the forming mold, the second protruding part of the side template, and the air inflation assembly respectively correspond to the light-transmitting groove, the installation groove, and the weight-reducing hole of the curbstone body. The combination of the lamp tube and the fixing sleeve of the curbstone can be pre-placed on the first protruding part, and both ends are fixed by the limiting parts on the second protruding part. Finally, after the concrete solidifies and forms, when the forming mold is removed, the curbstone body, the combination of the lamp tube and the fixing sleeve of the luminous curbstone can be obtained; (2) on the concrete batching unit, first, the forming mold is transported to the batching device through the mold input device, then the batching device transports the concrete into the forming mold and compacts it. Then, the mold output device receives the forming mold output from the batching device. Finally, the first palletizer palletizes the forming mold. After palletizing, it can be additionally transported to the steam curing chamber for integral curing by using a mother-daughter vehicle; (3) in the mold removal unit, first, the steam-cured forming mold is transported to the second palletizer by using a mother-daughter vehicle. The second palletizer transports the forming mold to the conveyor device one by one. Then, during the transportation of the forming mold along with the conveyor device, the forming mold is lifted upward by the lifting device, and the side template and the air inflation assembly of the forming mold are manually disassembled. Then, after resetting, the forming mold moves to the mold flipping device, and the forming mold is flipped 180 degrees. Then, when the forming mold moves to the vibrating mold removal device, the main template of the forming mold is separated from the combination of the curbstone body, the lamp tube, and the fixing sleeve by vibration. Finally, the forming mold is lifted away by the lifting device, and the combination of the curbstone body, the lamp tube, and the fixing sleeve is transported to the subsequent grinding machine for grinding.

After inflation, the inflatable air bag abuts against the inner sides of the flexible protective sleeve and the through hole. After the two inflatable air bags are inflated, the cross-section of the flexible protective sleeve matches the cross-section of the through hole. The surface of the flexible protective sleeve needs to be sprayed with a release agent during use.

[0059] Embodiment: A production line for luminous curb stones, as Figure 1 shown, includes a forming mold 1, a concrete mixer 2, a concrete distribution unit 3 for transporting concrete into the forming mold 1 and vibrating it solid, a steam curing chamber 4 for steam curing the concrete in the forming mold 1, a demolding unit 5 for removing the forming mold 1, and a grinding machine 6 for grinding the curb stone body after demolding.

[0060] As shown in Figures 1 to Figure 3 shown, the forming mold 1 includes a main template 11 with a "U"-shaped cross-section, a square frame 12 fixedly arranged on the periphery of the main template 11, two side templates 13 located on both sides of the main template 11 and detachably connected to the square frame 12 by bolts and nuts, and an air inflation assembly 14. A first protrusion 111 corresponding to the light-transmitting groove of the luminous curb stone is arranged at the bottom of the main template 11. Second protrusions 131 corresponding to the installation grooves of the luminous curb stone are arranged on both sides of the side template 13. A limiting portion 132 embedded in the end of the fixing sleeve of the luminous curb stone is arranged on the second protrusion 131. The lamp tube of the luminous curb stone is placed on the first protrusion 111 and two fixing sleeves are installed on the limiting portions 132 of the two side templates 13. A weight-reducing hole corresponding to the luminous curb stone and a through hole 133 in the shape of an "8" are arranged on the side template 13. After the air inflation assembly 14 is inflated, it fills the space corresponding to the through holes 133 of the two side templates 13 and both ends penetrate through the through holes 133.

[0075] Implementation effects: (1) In the molding die 1, the first protrusion 111 of the main template 11 of the molding die 1, the second protrusion 131 of the side template 13, and the air inflation assembly 14 respectively correspond to the light-transmitting groove, the installation groove, and the weight-reducing hole of the curbstone body. The combination of the lamp tube and the fixing sleeve of the curbstone can be pre-placed on the first protrusion 111 and fixed at both ends by the limiting part 132 on the second protrusion 131. Finally, after the concrete solidifies and forms, when the molding die 1 is removed, the combination of the curbstone body, the lamp tube, and the fixing sleeve of the luminous curbstone can be obtained; (2) On the concrete placing unit 3, first, the molding die 1 is transported to the placing device 31 through the die input device 32. Then, the placing device 31 transports the concrete into the molding die 1 and compacts it. Subsequently, the die output device 33 receives the molding die 1 output from the placing device 31. Finally, the first palletizer 34 palletizes the molding die 1, and after palletizing, it can be additionally transported to the steam curing chamber 4 by a mother-daughter vehicle for integral curing; (3) In the demolding unit 5, first, the steam-cured molding die 1 is transported to the second palletizer 51 by a mother-daughter vehicle. The second palletizer 51 transports the molding die 1 to the conveyor device 52 one by one. Then, during the transportation of the molding die 1 along with the conveyor device 52, the molding die 1 is lifted upward by the lifting device 53. The side template 13 and the air inflation assembly 14 of the molding die 1 are manually disassembled. Then, after resetting, the molding die 1 moves to the mold flipping device 54, and the molding die 1 is flipped 180 degrees. Subsequently, when the molding die 1 moves to the vibrating demolding device 55, the main template 11 of the molding die 1 is separated from the combination of the curbstone body, the lamp tube, and the fixing sleeve by vibration. Finally, the molding die 1 is lifted away by the lifting device 56, and the combination of the curbstone body, the lamp tube, and the fixing sleeve is transported to the subsequent grinding machine 6 for grinding.

[0076] Regarding the working principle of the air inflation assembly 14 of the molding die 1: The air inflation assembly 14 includes a flexible protective sleeve 141 and two inflatable air bags 142. After the two inflatable air bags 142 are inflated, the cross-section of the flexible protective sleeve 141 matches the cross-section of the through hole 133 to realize the weight-reducing hole corresponding to the curbstone body; and the setting of the flexible protective sleeve 141 can protect the inflatable air bags 142 to prevent the concrete from directly contacting the inflatable air bags 142, and can also support the two inflatable air bags 142 to reduce the deformation degree of the inflatable air bags 142.

[0077] Regarding the working principle of the concrete placing unit 3, it includes the working principle of the placing device 31, the working principle of the die input device 32, and the working principle of the die output device 33.

[0078] Principle of use of the fabricating device 31: When it is necessary to convey concrete into multiple forming molds 1, first, the second cylinder 3152 and the third cylinder 3154 simultaneously drive the hopper 3151 and the fabricating draw plate 3153 to move directly above the multiple forming molds 1, so that multiple fabricating channels 31511 correspond to the multiple forming molds 1. During this process, the fabricating partition plate 3155 enters the insertion slot 31512 to cover the tops of the multiple fabricating channels 31511. Then, the third cylinder 3154 drives the fabricating draw plate 3153 to reset. During this process, the concrete in the fabricating channels 31511 falls into the forming molds 1. Then, the third cylinder 3154 drives the fabricating draw plate 3153 to cover the bottom of the hopper 3151 again. Finally, the second cylinder 3152 and the third cylinder 3154 simultaneously drive the hopper and the fabricating draw plate 3153 to reset, thereby realizing the conveyance of the concrete in the multiple fabricating channels 31511 to the multiple forming molds 1 respectively, and the amount of concrete conveyed into the forming molds 1 can be controlled. When the limiting and vibrating mechanism 316 limits the connecting bottom frame 7, the driving component 3164 drives the first lifting plate 3161 to move upward, so that the limiting seat 31622 penetrates through the top of the discharging roller 312, so that the limiting seats 31622 of the placing strips 31621 on both sides of the first vibrating plate 3162 limit the corner of the connecting bottom frame 7. And when the driving component 3164 drives the first lifting plate 3161 to lift and lower in a small amplitude reciprocating manner, the settings of the first lifting plate 3161, the damping shock absorber 3163, and the first vibrating plate 3162 can, while maintaining the limiting effect on the connecting bottom frame 7, vibrate the concrete in the forming molds 1 to compact it. During the reciprocating expansion and contraction of the fourth cylinder 31646 of the driving component 3164, the pull rod 31645 and the swing arm 31644 drive the driving shaft 31641 to rotate a small angle reciprocally, thereby driving the nylon wheel 31643 to rotate a small angle reciprocally to adjust the maximum height of the nylon wheel 31643. Since multiple nylon wheels 31643 abut against the lower surface of the first lifting plate 3161, the first lifting plate 3161 is driven to reciprocally lift and lower, so as to vibrate and compact the concrete in the forming molds 1.

[0079] Principle of use of the mold input device 32: First, place both sides of the connecting bottom frame 7 on the first chain conveying mechanism 323. The first chain conveying mechanism 323 drives the connecting bottom frame 7 and the multiple forming molds 1 to be transported to one end close to the fabricating device 31. Then, the fifth cylinder 327 drives the pushing plate 326 to move downward and be located on the side of the connecting bottom frame 7 away from the fabricating device 31. Then, the first traveling mechanism 325 drives the traveling frame 324 to move towards the fabricating device 31, so that the pushing plate 326 pushes the connecting bottom frame 7 and the multiple forming molds 1 into the fabricating device 31.

[0080] Usage principle of the mold output device 33: After the connection bottom frame 7 and multiple forming molds 1 are output from the fabric device 31, the sixth cylinder 337 drives the second lifting plate 334 and the second vibrating plate 335 to move upward until they are higher than the second chain conveying mechanism 333, so as to receive the connection bottom frame 7 and multiple forming molds 1. And the setting of the first compression spring 336 can perform elastic buffering during the process of receiving the connection bottom frame 7 and multiple forming molds 1. Then, through the reciprocating lifting of the sixth cylinder 337, at this time, the setting of the second lifting plate 334, the second vibrating plate 335 and the first compression spring 336 can further compact the concrete in the forming mold 1. Then, the sixth cylinder 337 drives the second lifting plate 334 and the second vibrating plate 335 to move downward until they are lower than the second chain conveying mechanism 333, so that both sides of the connection bottom frame 7 are placed on the second chain conveying mechanism 333 for transmission.

[0081] The usage principle of the demolding unit 5 includes the usage principle of the conveying device 52, the usage principle of the lifting device 53, the usage principle of the mold turning device 54, the usage principle of the vibrating demolding device 55 and the usage principle of the hoisting device 56.

[0082] Usage principle of the conveying device 52: When the second palletizer 51 moves the palletized connection bottom frame 7 and multiple forming molds 1 onto the conveying device 52, the seventh cylinder 524 drives the first lifting frame 523 to be higher than the third chain conveying mechanism 522 first, so that the second palletizer 51 conveys the connection bottom frame 7 and multiple forming molds 1 onto the first lifting frame 523. Then, two eighth cylinders 527 drive two adjusting frames 525 to move, and the adjusting wheels 526 push both sides of the connection frame and multiple forming molds 1 to adjust their positions and angles, so that the connection frame and multiple forming molds 1 are located in the middle of the conveying machine frame 521. Finally, after the eighth cylinder 527 and the seventh cylinder 524 are reset, the connection frame falls into the third chain transmission mechanism, and the third chain conveying mechanism 522 drives the connection bottom frame 7 and multiple forming molds 1 to move.

[0083] Usage principle of the lifting device 53: During the transportation of the connection bottom frame 7 and multiple forming molds 1 along with the third chain conveying mechanism 522, when the connection bottom frame 7 touches the first stop post 531 for limiting, the tenth cylinder 534 drives the second lifting frame 533 to move upward to lift the connection bottom frame 7 upward, so that the two side templates 13 and the air inflation assembly 14 of the forming mold 1 can be manually removed. After the removal, the tenth cylinder 534 is reset, and the ninth cylinder 532 drives the first stop post 531 to move downward, so that the connection frame and multiple forming molds 1 continue to move along with the third chain conveying mechanism 522.

[0084] Usage principle of the mold turning device 54: When the connecting bottom frame 7 and multiple forming molds 1 (the side templates 13 and the air inflation components 14 have been disassembled) continue to move along with the third chain conveying mechanism 522, the connecting bottom frame 7 and the forming molds 1 are embedded in the clamping openings 5441 of the two turning clamping plates 544, and the reduction motor 543 drives the turning shaft 542 to rotate, so that the connecting bottom frame 7 and the forming molds 1 are turned 180 degrees and then fall onto the third chain conveying mechanism 522 to continue moving.

[0085] Usage principle of the vibration demolding device 55: After the connecting bottom frame 7 and multiple forming molds 1 touch the second stop post 551, the twelfth cylinder 556 drives the third lifting plate 553 and the third vibrating plate 554 to move upward, so that the connecting bottom frame 7 and the forming molds 1 are lifted upward and separated from the third chain conveying mechanism 522. Then, through the small reciprocating telescoping of the twelfth cylinder 556, the third lifting plate 553, the third vibrating plate 554 and multiple compression springs can drive, and the combination of the concrete body, the lamp tube and the fixing sleeve is separated from the forming mold 1 by vibration.

[0086] Usage principle of the lifting device 56: After the combination of the concrete body, the lamp tube and the fixing sleeve is separated from the forming mold 1, first, the second traveling mechanism 564 drives the two sliding frames 562 to move left and right, so that the sliding frame 562 with the first lifting hook claw 5610 moves directly above the vibration demolding device 55. The thirteenth cylinder 566 drives the lifting bracket 565 located above the vibration demolding device 55 to move downward, and the fourteenth cylinder 5611 drives the two first lifting hook claws 5610 to clamp both sides of the connecting bottom frame 7. Then, the thirteenth cylinder 566 drives the lifting bracket 565 to move upward, and the second traveling mechanism 564 drives the sliding frame 562 with the second lifting hook claw 5612 to move directly above the vibration demolding device 55; then, after the thirteenth cylinder 566 drives the lifting bracket 565 to descend, the fourteenth cylinder 5611 drives the first lifting hook claw 5610 to release the connecting bottom frame 7 for discharging. During this process, the thirteenth cylinder 566 drives the lifting bracket 565 located above the vibration demolding device 55 to move downward, and the fifteenth cylinder 5613 drives the two second lifting hook claws 5612 to clamp multiple forming molds 1, and then the discharging operation of the forming molds 1 is completed; finally, it is realized that multiple forming molds 1 can be clamped during the discharging process of the connecting bottom frame 7, and the next group of connecting bottom frames 7 can be clamped during the discharging process of the forming molds 1, improving the working efficiency; in addition, due to the setting of the rotating assembly 568, during the movement of the sixteenth cylinder 5684 driving the adjusting rack 5685, the driving gear 5681 meshing with it can be driven to rotate, so as to drive the rotating shaft 567 to rotate, so as to realize the adjustment of the angle of the clamping disc, and realize the operation of rotating the angle and then stacking during the discharging process.
