Description

Technical Field

[0001] The invention belongs to the field of polyethylene straight pipe butt welding, in particular to a polyethylene straight pipe butt welding wiring device. Background Art

[0002] Polyethylene material has good chemical stability. Because the polymer molecules are connected by carbon-carbon single bonds, it can withstand corrosion from most acids and alkalis, is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation properties. Therefore, it is often used as a pipe, for a protective layer, or for transporting various liquids.

[0003] A Chinese patent with publication number CN203831803U discloses a plastic straight pipe docking device, including a base and a hot-melt steel pipe, wherein the base is provided with four legs; a plurality of ventilation holes are provided at the bottom of the base; a carbon adsorption layer is provided on the ventilation holes; an exhaust fan is provided above the carbon adsorption layer; a plurality of air inlet holes are provided in the upper surface area of ​​the base corresponding to the exhaust fan; and the device can absorb toxic gases volatilized from the hot melt during hot welding and perform carbon adsorption purification.

[0004] During the docking process of straight pipes made of polyethylene, the docking surfaces of the straight pipes are generally hot-melted, and then the two straight pipes are pressed together and welded after cooling. However, during such a docking process, the ends of the straight pipes may be deformed due to hot melting, which may easily cause the two straight pipes to be not in a straight line after docking, resulting in reduced quality of the finished product. At the same time, when there are objects in the straight pipes, such as: the straight pipe is a protective cover for the wire, and the straight pipe breaks during use, the two straight pipes need to be docked. In this way, it is difficult to heat one circle of the straight pipe during hot melting, and attention should be paid to the internal objects during docking, which makes the working process extremely inconvenient. Hot-melt heating has another disadvantage, that is, when docking two very thick straight pipes, it is not only difficult to hot-melt the two ends of the straight pipes, but also because the straight pipes are heavy, the docking process is more laborious.

[0005] To this end, the present invention provides a polyethylene straight pipe butt welding wiring device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

After the driving seat rotates half a circle, metal wires are welded one by one on the outer half circle of the butt-jointed straight tubes. Then, the entire device is turned around or the butt-jointed straight tubes are flipped over, and the other half circle of the butt-jointed straight tubes are also welded. Through this setting, the flatness of the butt-jointed straight tube butt-jointed position is guaranteed, and deformation due to hot melting will not occur. At the same time, since the welding position is located on the outside of the butt-jointed straight tubes, the items inside the butt-jointed straight tubes will not be affected during the butt-jointing process.

Since the metal wire is tough, the bent metal wire will form an outward arch. Current is passed through two electrodes to heat the metal wire. As the moving rod moves, the metal wire can be pressed into the docking straight tube. After the metal wire is heated, its rigidity decreases, and the metal wire at the front end is fixed on the docking straight tube. As the moving rod retreats, the metal wire fixed on the surface of the docking straight tube and the unheated metal wire at the rear can be separated under the pulling action.

[0031] During operation, when the polyethylene tube wrapped with wires breaks, in order to protect the safety of the wires, the two ends of the polyethylene tube need to be welded and fixed. However, hot-melting the ends of the two tubes is likely to affect the internal wires, and the docking process will be affected by the obstruction of the wires, which will affect the operation process. At this time:

[0032] By setting the moving rail 4, the ends of the two butt-jointed straight pipes 1 to be butt-jointed are placed in the moving rail 4. The driving seat 5 can drive the driving seat 5 to move in a circular manner on the surface of the moving rail 4 under the drive of the two electric wheels 1. The two electric wheels 1 are installed in the driving seat 5, and the two electric wheels 1 clamp the moving rail 4 in the middle position. In this way, when the electric wheel 1 rotates, the driving seat 5 can slide on the surface of the moving rail 4. The sliding of the moving rod 6 is controlled by the electric wheel 2. The electric wheel 2 is installed in the driving seat 5. The two electric wheels 2 are attached to the surface of the moving rod 6 to clamp the moving rod 6. In this way, when the electric wheel 2 rotates, the moving rod 6 can be driven to slide, and the position of the end of the moving rod 6 can be adjusted, so that the butt-jointed straight pipes with different diameters can be connected. 1 is processed, the metal wire 12 is evenly distributed on the outside of the butt joint straight tube 1 through the welding assembly, and the metal wire 12 is heated at the same time, and then the metal wire 12 is pressed into the connection seam of the two butt joint straight tubes 1, and the metal wire 12 is kept perpendicular to the connection seam. After the driving seat 5 rotates half a circle, the metal wires 12 are welded one by one on the outer half circle of the butt joint straight tube 1, and then the whole device is turned over or the butt joint straight tube 1 is turned over, and the other half circle of the butt joint straight tube 1 is also welded. Through this arrangement, the flatness of the butt joint position of the butt joint straight tube 1 is guaranteed, and deformation due to hot melting will not occur. At the same time, since the welding position is located on the outside of the butt joint straight tube 1, the items inside the butt joint straight tube 1 will not be affected during the butt joint process.

[0033] like Figures 1 to 5 As shown, the top surface of the base 2 is open, a screw nut mechanism is installed on the inner side of the base 2, a moving end of the screw nut mechanism is fixedly connected to a moving seat 8, a support platform 7 is fixedly connected to the top of the moving seat 8, the top of the support platform 7 is connected to the moving rail 4, and receiving seats 3 for supporting the docking straight pipe 1 are provided on both sides of the base 2, and a support plate is slidably connected to one side of the support platform 7;

[0034] During operation, the two ends of the butt-jointed straight tube 1 are supported by two receiving seats 3 so that the butt-jointed part of the butt-jointed straight tube 1 is located in the movable rail 4. Since the connection gaps of the two butt-jointed straight tubes 1 are not necessarily in the same plane, the support platform 7 is driven to move by the screw nut mechanism, thereby driving the movable rail 4 and the welding assembly to move to align with the connection gap, so that the metal wire 12 can be accurately welded on both sides of the gap, so that the two butt-jointed straight tubes 1 can be firmly welded together. The support plate can adjust the height, and the top surface of the support plate is relatively smooth, which is used to support the middle part of the butt-jointed straight tube 1.

[0035] like Figures 1 to 5 As shown, the support platform 7 is slidably engaged with the movable rail 4, the support platform 7 and the driving seat 5 are staggered with each other, an electric gear is installed on the inner side of the support platform 7, a gear ring is fixedly connected to the side of the movable rail 4 away from the driving seat 5, and the electric gear is meshed with the gear ring;

[0036] During operation, after the outer half circle of the docking straight tube 1 is welded and fixed by the metal wire 12, the electric gear is started to rotate, driving the gear ring and the movable rail 4 to rotate as a whole, and the support platform 7 remains stationary, so that the movable rail 4 can rotate at most half a circle, and then the driving seat 5 performs another half circle welding work to complete the welding of the other half circle of the docking straight tube 1. Through this setting, there is no need to flip the docking straight tube 1, and the driving seat 5 can be allowed to circle around the outer side of the docking straight tube 1 to complete the docking work, thereby reducing manual preparation work and the problem of displacement of the docking straight tube 1 during flipping.

[0037] like Figures 1 to 5 As shown, the welding assembly includes a bending table 11, the metal wire 12 obliquely passes through the moving rod 6 and the bending table 11, the surface of the bending table 11 is slidably connected with a grabbing table 14, the grabbing table 14 is used to grab the end of the metal wire 12 and bend the metal wire 12, the outer side of the driving seat 5 is provided with a supply assembly, the supply assembly is used to reel in the metal wire 12, and continuously supply the metal wire 12 toward the bending table 11, and the inner side of the moving rod 6 and the grabbing table 14 are provided with electrodes in contact with the metal wire 12;

[0038] During operation, the metal wire 12 in the supply box 9 is continuously transferred to the bending table 11 through the supply component. The through hole opened by the bending table 11 for the metal wire 12 is curved, so the metal wire 12 will bend after passing through the bending table 11, and then the grabbing table 14 will grab the end of the metal wire 12 and make the metal wire 12 bend on the surface of the bending table 11. Since the metal wire 12 has toughness, the bent metal wire 12 will form an outward arch. Current is passed through the arched metal wire 12 through two electrodes to heat the metal wire 12. In this way, as the moving rod 6 moves, the metal wire 12 can be pressed into the docking straight tube 1. After the metal wire 12 is heated, the rigidity of the metal wire 12 is reduced, and the metal wire 12 at the front end is fixed on the docking straight tube 1. In this way, as the moving rod 6 retreats, the metal wire 12 that has been fixed on the surface of the docking straight tube 1 and the metal wire 12 that has not been heated at the rear can be separated under the pulling action. Then the supply component continues to supply in the direction of the bending table 11, and the welding work can be repeated.

[0039] like Figures 1 to 5 As shown, an optical camera 15 is fixedly connected to the bottom of the driving seat 5, the observation end of the optical camera 15 faces the docking straight pipe 1, and the optical camera 15 is communicatively connected with the lead screw nut mechanism and the electric gear;

[0040] During operation, the connection gap between the two butt-jointed straight tubes 1 can be observed through the optical camera 15, and the optical camera 15 can transmit the observed position information to the screw nut mechanism through wireless communication, thereby controlling the sliding of the moving seat 8, so that the moving rod 6 can always be maintained at the connection gap between the two butt-jointed straight tubes 1.

[0041] like Figures 1 to 5 As shown, the supply assembly includes a supply box 9, an electric winding roller is installed inside the supply box 9, the metal wire 12 is wound around the outside of the electric winding roller, a binding tube 10 is fixedly connected to the outside of the supply box 9, two electric wheels 3 are installed inside the binding tube 10, and the metal wire 12 passes between the supply box 9 and the two electric wheels 3 in the binding tube 10;

[0042] During operation, the metal wire 12 is continuously released by the electric telescopic roller, and at the same time, the two electric wheels 3 in the binding tube 10 continuously transport the metal wire 12 toward the bending platform 11, thereby completing the transportation and supply process of the metal wire 12.

[0043] like Figures 1 to 5 As shown, a guillotine table 13 is installed on the inner side of the moving rod 6, the metal wire 12 passes through the guillotine table 13, and the electrode in the moving rod 6 is located between the guillotine table 13 and the bending table 11;

[0044] During operation, the shearing table 13 can cut off the end of the metal wire 12 after the metal wire 12 is bent and formed, so that after the metal wire 12 is welded and fixed to the butt straight pipe 1, the welded metal wire 12 is separated from the rear metal wire 12.

[0045] like Figures 1 to 5 As shown, there is an angle between the grabbing platform 14 and the moving rod 6, an electric wheel four is installed inside the bending platform 11, and the electric wheel four is in driving contact with the surface of the grabbing platform 14, and a grabbing component is provided on the surface of the bending platform 11, and the grabbing component is used to grab the metal wire 12;

[0046] During operation, when the metal wire 12 is pushed out from the bending table 11, the electric wheel four-drive grabbing table 14 is pushed out. At this time, the pushed-out metal wire 12 will dock with the grabbing component, and the grabbing component will grab the end of the metal wire 12. After grabbing, the grabbing table 14 returns to its position, and the metal wire 12 can be bent.

[0047] like Figures 1 to 5 As shown, the grabbing assembly includes a solenoid valve 16, a groove is formed on the surface of the grabbing platform 14, the solenoid valve 16 is fixed in the groove, the valve port of the solenoid valve 16 faces outward, the valve port diameter of the solenoid valve 16 is larger than the diameter of the metal wire 12, and the electrode of the grabbing platform 14 is located in the solenoid valve 16;

[0048] During operation, the end of the metal wire 12 will be inserted into the solenoid valve 16 and contact the electrode in the solenoid valve 16. After the solenoid valve 16 fixes the end of the metal wire 12, as the grabbing table 14 returns to its position, the metal wire 12 can be bent outward into an arch shape. After welding is completed, the solenoid valve 16 opens to release the metal wire 12, so that the metal wire 12 can remain on the outside of the docking straight pipe 1.

[0049] like Figures 1 to 5 As shown, the surfaces of the bending table 11 and the grabbing table 14 are both provided with a notch groove 17, and the bending table 11 and the grabbing table 14 are both made of high-temperature resistant metal. When working, the setting of the notch groove 17 can reduce the contact area between the grabbing table 14 and the metal wire 12, and reduce the thermal damage of the grabbing table 14.

[0050] When working, the ends of the two butt joint straight tubes 1 that need to be butted are placed on the butt joint rail 4 through the setting of the moving rail 4. The driving seat 5 can drive the driving seat 5 to move in a circular manner on the surface of the moving rail 4 under the drive of the two electric wheels 1. The sliding of the moving rod 6 is controlled by the electric wheel 2 to adjust the position of the end of the moving rod 6. In this way, the butt joint straight tubes 1 of different diameters can be processed. The metal wires 12 are evenly distributed on the outside of the butt joint straight tube 1 through the welding assembly. At the same time, the metal wires 12 are heated. Then, the metal wires 12 are pressed into the connecting seams of the two butt joint straight tubes 1. The metal wires 12 are kept perpendicular to the connecting seams. After the driving seat 5 rotates half a circle, the metal wires 12 are welded one by one on the outer half circle of the butt joint straight tube 1. Then, the whole device is turned over or the butt joint straight tube 1 is turned over, and the other half circle of the butt joint straight tube 1 is also welded. Through this setting, the flatness of the butt joint position of the butt joint straight tube 1 is guaranteed, and deformation due to hot melting will not occur. At the same time, since the welding position is located on the outside of the butt joint straight tube 1, the items inside the butt joint straight tube 1 will not be affected during the butt joint process.

[0051] The two ends of the butt joint straight tube 1 are supported by two receiving seats 3, so that the butt joint part of the butt joint straight tube 1 is located in the movable rail 4. Since the connection gaps of the two butt joint straight tubes 1 are not necessarily in the same plane, the support platform 7 is driven to move by the screw nut mechanism, thereby driving the movable rail 4 and the welding assembly to move to align with the connection gap, so that the metal wire 12 can be accurately welded on both sides of the gap, so that the two butt joint straight tubes 1 can be firmly welded together. The support plate can adjust the height, and the top surface of the support plate is relatively smooth, which is used to support the middle part of the butt joint straight tube 1;

[0052] After the outer half circle of the docking straight tube 1 is welded and fixed by the metal wire 12, the electric gear is started to rotate, driving the gear ring and the movable rail 4 to rotate as a whole, and the support platform 7 remains stationary, so that the movable rail 4 can rotate at most half a circle, and then the driving seat 5 performs another half circle welding work to complete the welding of the other half circle of the docking straight tube 1. Through this setting, there is no need to flip the docking straight tube 1, and the driving seat 5 can be allowed to circle around the outer side of the docking straight tube 1 to complete the docking work, thereby reducing manual preparation work and the problem of the docking straight tube 1 being offset when flipping;

[0053] The metal wire 12 in the supply box 9 is continuously transferred to the bending table 11 through the supply component. The through hole opened by the bending table 11 for the metal wire 12 is curved, so the metal wire 12 will bend after passing through the bending table 11, and then the grabbing table 14 will grab the end of the metal wire 12 and make the metal wire 12 bend on the surface of the bending table 11. Since the metal wire 12 has toughness, the bent metal wire 12 will form an outward arch. Electric current is passed through the arched metal wire 12 through two electrodes to heat the metal wire 12. In this way, as the moving rod 6 moves, the metal wire 12 can be pressed into the docking straight tube 1. After the metal wire 12 is heated, the rigidity is reduced, and the metal wire 12 at the front end is fixed on the docking straight tube 1. In this way, as the moving rod 6 is withdrawn, the metal wire 12 that has been fixed on the surface of the docking straight tube 1 and the metal wire 12 that has not been heated at the rear can be separated under the pulling action. Then the supply component continues to supply in the direction of the bending table 11, and the welding work can be repeated.

[0054] The connection gap between the two butt-jointed straight pipes 1 can be observed by the optical camera 15, and the optical camera 15 can control the moving seat 8 to slide, so that the moving rod 6 can always be maintained at the connection gap between the two butt-jointed straight pipes 1;

[0055] The metal wire 12 is continuously released by the electric telescopic roller, and at the same time, the two electric wheels 3 in the binding tube 10 continuously transport the metal wire 12 toward the bending table 11, thereby completing the transportation and supply process of the metal wire 12;

[0056] The guillotine table 13 can cut off the end of the metal wire 12 after the metal wire 12 is bent and formed, so that after the metal wire 12 is welded and fixed to the butt straight pipe 1, the welded metal wire 12 is separated from the rear metal wire 12;

[0057] When the metal wire 12 is ejected outward from the bending table 11, the electric wheel four-drive grabbing table 14 is ejected outward, and the ejected metal wire 12 will dock with the grabbing assembly, and the grabbing assembly will grab the end of the metal wire 12. After grabbing, the grabbing table 14 returns to its position, and the metal wire 12 can be bent;

[0058] The end of the metal wire 12 will be inserted into the solenoid valve 16 and contact the electrode in the solenoid valve 16. After the solenoid valve 16 fixes the end of the metal wire 12, as the grabbing table 14 returns to its position, the metal wire 12 can be bent outward into an arch shape. After the welding is completed, the solenoid valve 16 is opened to release the metal wire 12, so that the metal wire 12 can be left outside the butt-jointed straight pipe 1;

[0059] The provision of the notch groove 17 can reduce the contact surface between the grabbing platform 14 and the metal wire 12 , thereby reducing thermal damage to the grabbing platform 14 .
