Description

Technical Field

[0001] The present invention relates to the technical field of pipeline marking, in particular to a laser marking device for water conservancy pipeline production. Background Art

[0002] Water conservancy pipelines are tubular facilities used to transport water resources (such as drinking water, irrigation water, industrial water, etc.) and discharge sewage, rainwater, etc. They play a vital role in water conservancy projects and are key infrastructure to ensure the rational allocation, utilization and discharge of water resources. In the production of water conservancy pipelines, traditional marking methods (such as inkjet coding and labeling) have problems such as easy wear, poor durability, and insufficient environmental protection. They are difficult to meet the needs of long-term burial or harsh environments. In addition, traditional processes rely on consumables (inks, labels), which are costly and easy to pollute the environment. With the increasing requirements for pipeline quality traceability and anti-counterfeiting in water conservancy project construction, an efficient, environmentally friendly and durable marking technology is urgently needed. Laser marking has become an ideal choice to replace traditional processes due to its advantages such as non-contact processing, high precision and permanent marking. However, existing laser marking equipment has shortcomings in dynamic marking accuracy, multi-material adaptability and production line integration. Special devices need to be developed to achieve efficient and stable pipeline marking.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1-2 As shown, a laser marking device for water conservancy pipeline production includes a bracket 1, the upper end of the bracket 1 is fixedly connected to a left-right symmetrical workbench 5, the upper ends of the two workbench 5 are commonly fixedly connected to a conveying mechanism 7, the upper end of the left workbench 5 is fixedly connected to a motor 6, the upper end of the left workbench 5 is fixedly connected to a driving component 2, the rear end of the right workbench 5 is fixedly connected to a connecting plate 9, the outer surface of the connecting plate 9 is provided with a marking mechanism 8, the lower side of the marking mechanism 8 is fixedly connected to a bracket 2, and the upper end of the bracket 24 is fixedly connected to an industrial computer 3.

[0032] It should be noted that the drive component 2 consists of a motor 6 and a pulley. The specific installation method, circuit connection method, and control method of the motor 6 and the industrial computer 3 are all conventional designs and are the designer's conventional design methods. The industrial computer 3 is the control center of the laser marking machine, equivalent to a computer host. It runs dedicated marking software, is responsible for processing graphics, text, and other data, and sends instructions to the laser and galvanometer scanning system to achieve precise marking operations. In addition, the installation of a connecting plate 9 facilitates the marking mechanism 8 to point. When the marking mechanism 8 is connected to the connecting plate 9, the marking mechanism 8's marking point is directly above the water conservancy pipeline transported to the conveyor mechanism 7.

[0033] First, a judgment is made based on the diameter of the produced water conservancy pipeline, and motor 16 is started. The conveying mechanism 7 is adjusted by motor 16 so that the conveying mechanism 7 can be suitable for the produced water conservancy pipeline. The water conservancy pipeline is transported to the conveying mechanism 7 by external transportation equipment. With the cooperation of the industrial computer 3, the marking mechanism 8 performs laser marking on the upper side of the outer surface of the water conservancy pipeline, and finally achieves the purpose of laser marking water conservancy pipelines of different diameters, increasing the scope of application of the device. In addition, when it is necessary to perform rotational marking on the surface of the water conservancy pipeline, the conveying mechanism 7 is driven to operate by the driving component 2, and then the water conservancy pipeline to be marked is transported to the conveying mechanism 7 by external transportation equipment. The water conservancy pipeline is rotated by the conveying mechanism 7, and with the cooperation of the industrial computer 3 and the marking mechanism 8, the operation of rotational marking on the surface of the water conservancy pipeline is completed.

[0034] In order to complete the laser marking operation on water conservancy pipelines, such as Figure 3 and Figure 4 As shown, the marking mechanism 8 includes a rectangular column 81, a clamping plate 89 is fixedly connected to the middle of the right end of the rectangular column 81, a mounting groove 82 is provided on the upper front end of the rectangular column 81, a threaded rod 3 891 is rotatably connected to the inner cavity of the mounting groove 82, a slide 86 is provided on the outer surface of the threaded rod 3 891 and the inner cavity of the mounting groove 82, a rectangular column 83 is fixedly connected to the left end of the slide 86, a mounting groove 2 84 is provided on the upper end of the rectangular column 83, a screw 1 85 is rotatably connected to the inner cavity of the mounting groove 2 84, a marking component 87 is provided on the outer surface of the screw 1 85 and the inner cavity of the mounting groove 2 84, an auxiliary group 88 is provided on the left side of the marking component 87, the lower end of the rectangular column 81 is fixedly connected to the right side of the upper end of the bracket 2 4, and the inner cavity of the clamping plate 89 is slidably connected to the outer surface of the connecting plate 9.

[0035] It should be noted that the marking component 87 is composed of a laser marking machine, a sliding seat and a connecting rod that are compatible with the outer surface of the screw 1 85 and the inner cavity of the mounting groove 2 84. The specific installation method of the laser marking machine and the circuit connection method and control method are all conventional designs, which are conventional design means of designers. The laser marking machine is connected to the industrial computer 3 and used in conjunction with each other.

[0036] First, when the clamping plate 89 is clamped on the surface of the connecting plate 9, the marking center of the laser marking machine in the marking component 87 is just located in the middle of the upper side of the outer surface of the water conservancy pipeline transported to the conveying mechanism 7. Then, according to the actual requirements of the laser marking distance, the threaded rod 3 891 is rotated to drive the slide 86 to move up and down in the inner cavity of the mounting groove 1 82 to a suitable position, and the lower side of the auxiliary group 88 is against the middle of the upper side of the outer surface of the water conservancy pipeline. When the water flow pipeline is transported horizontally in the conveying mechanism 7, the cooperation of the industrial computer 3 enables the marking component 87 to perform laser marking on the upper side of the outer surface of the water conservancy pipeline, and During the horizontal transportation of the water conservancy pipeline in the transportation mechanism 7, the auxiliary group 88 rolls on the surface of the water conservancy pipeline, which increases the stability of the laser marking of the water conservancy pipeline by the marking component 87. Secondly, the auxiliary group 88 can also remove foreign matter on the upper side of the outer surface of the water conservancy pipeline so that it does not affect the quality of the laser marking of the water conservancy pipeline. In addition, according to actual needs, the screw 1 85 can be rotated to drive the marking component 87 to move back and forth on the outer surface of the screw 1 85 and the inner cavity of the installation groove 2 84, so as to adjust the front and back distance of the marking component 87, making the device more flexible in use.

[0037] Further explanation, such as Figure 5 As shown, the auxiliary group 88 includes a shell plate 881, the rear end of the shell plate 881 is fixedly connected to the left side of the marking component 87, the inner cavity of the shell plate 881 is rotatably connected to the threaded rod 882, the outer surface of the threaded rod 882 and the inner cavity of the shell plate 881 are jointly provided with a threaded block 883, the front end of the threaded block 883 is fixedly connected to a connecting rod 884, a pressure wheel component 887 is provided on the lower right part of the outer surface of the connecting rod 884, an auxiliary wheel component 885 is provided on the left side of the outer surface of the connecting rod 884, and a scraper 886 is provided on the middle part of the left side of the outer surface of the auxiliary wheel component 885.

[0038] In detail, the pressure wheel component 887 is composed of a roller and a fixing frame, and the auxiliary wheel component 885 is composed of a roller, a flexible dust-cleaning outer ring pad and a fixing frame. The flexible dust-cleaning outer ring pad is fixed on the outer surface of the roller, and the flexible dust-cleaning outer ring pad is slightly lower than the roller in the pressure wheel component 887. When the water conservancy pipeline is transported straight from left to right in the conveying mechanism 7, the roller in the pressure wheel component 887 can roll on the water conservancy pipeline, and at the same time, the roller in the auxiliary wheel component 885 drives the flexible dust-cleaning outer ring pad to lightly press on the water conservancy pipeline and also roll, while rolling. The outer ring pad removes foreign matter on the water conservancy pipe, and the scraper 886 scrapes off foreign matter on the flexible cleaning outer ring pad while the flexible cleaning outer ring pad rotates. Secondly, the pressure wheel component 887 rolls on the water conservancy pipe, making the marking component 87 more stable when laser marking the water conservancy pipe. In addition, by rotating the threaded rod 882, the threaded block 883 cooperates with the connecting rod 884 to drive the pressure wheel component 887 and the auxiliary wheel component 885 to move vertically up and down to the appropriate position, so that it can be adjusted up and down according to the actual laser marking distance requirements.

[0039] Example 2: This example is based on Example 1 and assists 8 to complete the laser marking operation. Figure 6 、 Figure 7 and Figure 8 As shown, the conveying mechanism 7 includes two outer shells 71, and the two outer shells 71 are fixedly connected to a fixed disk 72. The opposite surfaces of the two fixed disks 72 are provided with three sliding grooves 74 in a circular array. The left and right ends of the two fixed disks 72 are fixedly connected with front and rear symmetrical arc-shaped slide rails 75. The two inner cavities of the two outer shells 71 are away from each other. A conveying group 73 is provided on the side where the inner cavities of the two outer shells 71 are close to each other. A rotating group 76 is provided on the side where the inner cavities of the two outer shells 71 are close to each other. The lower ends of the two outer shells 71 are respectively fixedly connected to the upper ends of the two workbenches 5. The conveying group 73 includes two convex turntables 732. The ends of the two convex turntables 732 away from each other are provided with three arc grooves 733 in a circular array. The inner cavities of the three arc grooves 733 on the same side are all slidably connected to support parts. Part 1 736, the outer surfaces of the two convex turntables 1 732 are fixedly connected to the ring gear 1 738, the outer surfaces of the two ring gears 738 are meshed with the transmission component 1 734, the outer surface of the transmission component 1 734 is symmetrically connected to the support 1 735, the lower ends of the two supports 1 735 are respectively fixedly connected to the two outer shells 71, the opposite surfaces of the two convex turntables 1 732 are provided with a rotation groove 1 737, the outer surfaces of the two arcuate slide rails 75 on the same side are rotatably connected to the inner cavity of the rotation groove 1 737, the right end of the transmission component 1 734 passes through the inner cavity of the outer shell 71 on the same side and is fixedly connected to the output end of the motor 6, and the three supporting components 1 736 on the same side are away from the right side of the convex turntable 1 732 and are respectively slidably connected to the inner cavities of the three sliding grooves 74.

[0040] It should be noted that the transmission component 734 is composed of two toothed discs and a rotating shaft, and the rotating shaft passes through the inner cavity of the shell 71 and is fixedly connected to the output end of the motor 6. The support component 736 is composed of a T-shaped plate, a cylinder, a sliding block and a supporting double roller. The cylinder can slide in the inner cavity of the arc groove 733, and the sliding block can slide in the inner cavity of the sliding groove 74. After judging the diameter of the production water conservancy pipeline, the motor 6 is started to drive the transmission component 734 to rotate, so that the left and right symmetrical toothed discs in the transmission component 734 respectively drive the left and right symmetrical toothed discs to rotate. The gear ring 738 rotates, and with the cooperation of the rotating groove 737, the convex turntables 732 on the left and right sides rotate respectively on the outer surface of the arc-shaped slide rail 75 and the inner cavity of the shell 71 on the same side, and with the cooperation of the arc-shaped groove 733 and the sliding groove 74, the three supporting components 736 on the left and right sides move toward each other to the appropriate positions at the same time, clamping the water pipe without affecting the linear transportation of the water pipe, so that the device can be applied to water pipes of different diameters, and cooperate with the marking mechanism 8 to complete the laser marking operation.

[0041] Further explanation, such as Figure 6 and Figure 9 As shown, the rotating group 76 includes two convex rotating disks 762, and the opposing surfaces of the two convex rotating disks 762 are provided with three arc-shaped grooves 767 in a circular array. The inner cavities of the arc-shaped grooves 767 located on the lower side are symmetrical on the left and right, and the inner cavities of the two arc-shaped grooves 767 located on the upper side are symmetrical on the left and right, and the supporting components 768 are slidably connected. The ends of the two convex rotating disks 762 that are away from each other are provided with rotating grooves 761.

[0042] Slender, it should be noted that the transmission component 2 764 is composed of two toothed discs with through holes and a round tube. The toothed disc with holes is adapted to the gear ring 2 763. The support component 2 768 is composed of a T-shaped plate, a cylinder, a sliding block and a supporting single roller. The cylinder can slide in the inner cavity of the arc groove 2 767, and the sliding block can slide in the inner cavity of the sliding groove 74. When it is necessary to perform rotary marking on the water conservancy pipeline, the driving component 2 is started and the belt and the transmission wheel 1 766 are used in conjunction to drive the transmission component 2 764 to rotate in the inner cavity of the support 2 765. Through the rotation of the transmission component 2 764 and the use of the rotating groove 2 761, the left and right The convex turntables 2 762 on both sides rotate respectively on the outer surface of the arc-shaped slide rail 75 and the inner cavity of the shell 71 on the same side. Through the rotation of the convex turntable 2 762, with the cooperation of the arc-shaped groove 2 767 and the sliding groove 74, the two supporting components 2 768 and the brake group 769 on the left and right sides move toward each other to the appropriate position with the water pipe as the axis, and clamp the water pipe. The brake groups 769 on the left and right sides drive the water pipe to rotate, and the rotary marking operation of the water pipe is completed by the marking mechanism 8, so that the device can perform rotary marking on water pipes of different diameters, further increasing the scope of application of the device.

[0043] Further explanation, such as Figure 10As shown, the two brake groups 769 each include a sliding support plate 7691, the upper ends of the two sliding support plates 7691 are fixedly connected to roller components 7693, the middle parts of the outer surfaces of the two sliding support plates 7691 are fixedly connected to motor 2 7692, the output ends of the two motor 2 7692 and the sides of the outer surfaces of the two roller components 7693 that are away from each other are fixedly connected to transmission wheels 2 7694, the two transmission wheels 2 7694 on the same side are connected by belts, the sides of the two sliding support plates 7691 that are away from each other are respectively slidably connected to the inner cavities of the two sliding grooves 74 on the lower side, and the sides of the two sliding support plates 7691 that are close to each other are respectively slidably connected to the inner cavities of the two arc-shaped grooves 2 767 on the lower side.

The roller component 7693 is composed of a U-shaped frame and a rotating wheel. The rotating wheel can rotate on the U-shaped frame, and the transmission wheel 2 7694 located on the upper side is fixedly connected to the rotating wheel. The specific installation method of the motor 2 7692 and the circuit connection method and control method are all conventional designs, which are conventional design means of designers. By starting the motor 2 7692, the rotating wheel in the roller component 7693 is driven to rotate under the cooperation of the two transmission wheels 2 7694 and the belt. The rotation of the rotating wheel drives the water conservancy pipeline and the rotating wheel to rotate in the opposite direction. At this time, the water conservancy pipeline can be laser marked in conjunction with the marking mechanism 8.
