Description

Technical Field

[0001] The utility model relates to the technical field of metal welding, in particular to a gravure plate roller welding seam device. Background Art

[0002] The gravure roller is one of the common equipment in the printing field, used for gravure printing. Gravure printing is a graphic printing technology that transfers ink to an uneven surface and then transfers it to the printed object to achieve the printing process. The gravure roller is the roller used to transfer ink in gravure printing.

[0003] The gravure roller is usually made of metal plates that are processed to form a gravure pattern on the surface for printing. During the production process, workers bend the metal plates, align the two ends, and use a welding gun to weld them so that the welds are connected to form a cylindrical shape for subsequent installation on the roller shaft.

[0004] Since manual welding is currently adopted, when welding the bent gravure plate, a manual clamp is used to position the bent gravure plate. However, since manual welding requires adjusting the angle according to the welding adjustment, the welding angle of the gravure plate needs to be manually adjusted many times, which reduces the processing efficiency of the welding weld. In addition, due to the different proficiency of manual welding technology, the use of welding rods will increase, which increases the production cost. Summary of the invention

[0005] The utility model aims to provide a gravure printing plate roller welding device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gravure plate roller welding device, comprising a welding frame and a positioning structure; an adjusting motor is arranged on the outer wall of the welding frame, a rotating shaft of the adjusting motor is clamped with a transmission shaft, and the transmission shaft is located on the inner side of the welding frame; the positioning structure is connected to one end of the transmission shaft, and the positioning structure comprises a connecting shaft rotatably connected to a cross bar at one end of the transmission shaft, a welding shaft plugged into the connecting shaft, a positioning rod welded to the outer wall of one end of the welding shaft, a positioning seat welded to the positioning rod, a stud threadedly connected to the inside of the positioning seat and a rubber sheet adhered to the bottom end of the stud, and two groups of the positioning rod and the positioning seat are arranged above the outer wall of the welding shaft.

[0007] By adopting the above technical scheme, the gravure plate is manually attached to the welding shaft so that the weld is in the middle of the positioning rod, and the rubber sheet can be pressed on the gravure plate by tightening the studs respectively, so that the gravure plate can be firmly connected to the outer wall of the welding shaft, and the transmission shaft and the connecting shaft are driven by the adjusting motor to rotate, and the angle of the weld of the gravure plate can be adjusted for welding. The above structure can be used to limit the gravure plate and adjust the angle for positioning, and there is no need to adjust the angle of the gravure plate during welding, thereby ensuring the quality of the weld after welding and improving the processing efficiency of the welding weld.

[0008] Preferably, the positioning structure further comprises a socket provided at one end of the positioning rod and one end of the welding shaft, a support head plugged into the socket, and a welding groove provided on the outer wall of the welding shaft.

[0009] By adopting the above technical solution, by inserting the support head into the socket, the suspended end of the positioning rod can be connected to provide support, ensuring that the positioning rod provides stable supporting force when limiting the gravure plate. At the same time, the gravure plate forms a cylindrical shape after welding. By pulling out the support head and opening one end of the positioning rod, the gravure plate can be pulled out of the welding axis, solving the problem of difficulty in removing the gravure plate after welding with the automatic rotation adjustment function.

[0010] Preferably, a pressure shaft structure is provided on the upper surface of one end of the welding frame, and the pressure shaft structure includes a pressure cover rotatably connected to the upper surface of the welding frame, a limiting column welded to the upper surface of the welding frame, and a blocking strip inserted on the inner wall of the limiting column. One end of the connecting shaft is supported in a circular groove on the upper surface of one end of the welding frame, and a pressure cover is crimped on the upper surface of the connecting shaft.

[0011] By adopting the above technical solution, if the gravure plate needs to be removed from one end of the welding shaft after welding, the blocking bar can be pulled out from the limiting column through the pressing shaft structure. At this time, the pressure cover limit is released and can be rotated, so that the connecting rod can be rotated on the cross bar at one end of the transmission shaft, so as to achieve the effect of opening one end of the connecting shaft. At this time, the gravure plate can be smoothly pulled out from here, which solves the problem of difficulty in removing the gravure plate after welding with automatic rotation adjustment function.

[0012] Preferably, the inner wall of the welding frame is provided with a welding structure, which includes a sliding rod welded to the inner wall of the welding frame, a screw rotatably connected to the inner wall of the welding frame, a driving motor connected to one end of the screw, a movable seat threadedly connected to the outer wall of the screw, and an argon arc welding gun arranged on the movable seat.

[0013] By adopting the above technical solution, the movable seat can move on the sliding rod by the action of driving the motor to rotate the screw, and the argon arc welding gun can be moved together during the movement to quickly weld the welds on the moving path, thereby solving the problem of inconsistent welding effects caused by inconsistent manual welding technology, effectively controlling the number of welding rods used, reducing the cost of welding production, and improving the effect of welding welds.

[0014] Preferably, both ends of the movable seat are slidably connected to the sliding rod, and the welding wire at one end of the argon arc welding gun is vertically aligned on the tangent of the outer wall of the welding shaft.

[0015] By adopting the above technical solution, the moving seat is slidably connected to the sliding rod, which can provide a supporting force for supporting the moving seat, so that it can slide when moving, thereby improving the stability of the weld during welding. At the same time, the welding wire of the argon arc welding gun is aligned with the tangent of the outer wall of the welding shaft, so that the welding wire can be in the middle position of the weld during horizontal welding, which can improve the stability and uniformity of the weld. In addition, the distance from the welding wire to both sides during welding is relatively stable, which can more effectively control the welding speed and avoid welding quality problems caused by too fast or too slow.

[0016] Preferably, the outer wall of the positioning rod is evenly provided with three groups of positioning seats, studs and rubber sheets of the same structure, and the welding groove is located in the middle position of the two groups of positioning rods.

[0017] By adopting the above technical solution, the gravure plate is fixed by abutting at multiple points on one end, so that the stability of fixing one end of the gravure plate can be improved, and the bottom welding groove can prevent the molten metal from adhering to the welding shaft during welding, so that the gravure plate can be removed easily after welding.

[0018] Preferably, four groups of plugs of the same length are provided on one side of the support head, and the four groups of plugs are respectively inserted into four groups of sockets at corresponding positions, and the heights from both ends of the positioning rod to the outer wall of the welding shaft are the same.

[0019] By adopting the above technical solution, two groups of positioning rods are supported by supporting heads with the same height after being plugged in, and one end of the positioning rod can be supported and opened according to needs, which is convenient for welding and the removal of the gravure plate after welding.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The gravure plate is manually attached to the welding shaft so that the weld is in the middle of the positioning rod. When the studs are tightened respectively, the rubber sheet can be pressed on the gravure plate, so that the gravure plate can be firmly connected to the outer wall of the welding shaft. When the transmission shaft and the connecting shaft are driven by the adjusting motor to rotate, the angle of the weld of the gravure plate can be adjusted for welding. The gravure plate can be limited and then adjusted to position at an angle through the above structure. There is no need to adjust the angle of the gravure plate during welding, which ensures the quality of the weld after welding and improves the processing efficiency of the welding weld.

[0022] By driving the motor to rotate the screw, the moving seat can move on the sliding rod due to the thrust of the rotating screw. During the movement, the argon arc welding gun will move together to quickly weld the welds on the moving path, solving the problem of inconsistent welding effects caused by inconsistent manual welding technology, effectively controlling the number of welding rods used, reducing the cost of welding production, and improving the effect of welding welds.
