During welding, the square greenhouse grid is installed, the top motor is turned on to drive the longitudinal screw to rotate, and the height of the lifting shell is adjusted to make the welding end of the plasma arc welding module located at the welding point between the grids. During welding, the control side motor drives the transverse screw to rotate, thereby driving the welding mechanism to perform horizontal displacement to achieve linear welding of the grid. During this process, the weld processing wheel can also roll on the weld after the grid is welded.

One end of the output shaft of the control motor 64 is fixedly mounted with a first mounting frame 62 through a rotating shaft. A leakage groove 63 is provided at the bottom of the first mounting frame 62. Grid positioning components 61 are provided at the four corners of the top surface of the first mounting frame 62. The grid positioning component 61 includes a grid positioning frame 612, which is slidably mounted on the top surface of the first mounting frame 62. Positioning springs 611 are fixedly mounted on the outer walls on both sides of the grid positioning frame 612, and one end of the positioning spring 611 is fixedly connected to the inner wall of one side of the first mounting frame 62.

[0048] The specific implementation method is as follows: when welding the greenhouse grids, the greenhouse grids in four directions are first installed at the four corners of the first mounting frame 62 respectively. The grid positioning components 61 at the four corners of the first mounting frame 62 can squeeze the four greenhouse grids and piece together the four greenhouse grids into a larger grid. After the welding mechanism 7 welds the longitudinal center lines of the four grids, the control motor 64 can be turned on to drive the first mounting frame 62 to rotate 90° to weld the other center lines of the four grids. At the same time, when processing the weld, the processed impurities can leak down to the material guide inclined plate 51 through the leakage groove 63 of the first mounting frame 62. After waiting for a period of time, the side baffle 52 can be opened to centrally process the impurities.

[0049] Through this design, not only can the rapid installation and positioning of multiple greenhouse grids be completed, but the position of the greenhouse grids can also be quickly adjusted during the welding process, greatly improving the welding efficiency of the greenhouse grids. At the same time, weld impurities can be stably collected, and the overall equipment cleanliness is high.

[0050] The welding mechanism 7 includes a movable shell 71 and a plasma arc welding module 76 . The plasma arc welding module 76 is fixedly mounted on the bottom surface of the movable shell 71 . A bottom groove 73 and a mounting groove 77 are arranged on the bottom surface of the movable shell 71 . An inner card groove 72 is arranged on the inner side of the bottom groove 73 .

[0051] A weld processing assembly 78 is movably installed inside the mounting groove 77, and the weld processing assembly 78 includes a second mounting frame 782, which is slidably installed inside the mounting groove 77, and a telescopic spring 781 is fixedly installed on the top surface of the second mounting frame 782, and the top of the telescopic spring 781 is fixedly connected to the inner wall of one side of the mounting groove 77, and a mounting shaft 783 is rotatably installed on the inner side of the second mounting frame 782, and a weld processing wheel 784 is fixedly installed at the middle position of the mounting shaft 783, and driving wheels 785 are fixedly installed on both sides of the weld processing wheel 784 and located outside the mounting shaft 783, and a plurality of processing convex particles 787 are arranged on the outer surface of the weld processing wheel 784.

[0052] Side blowing assemblies 786 are rotatably mounted on the inner walls of both sides of the second mounting frame 782. The side blowing assemblies 786 include a rotating shaft 7862. A driven wheel 7863 and a blade 7861 are fixedly mounted on the outside of the rotating shaft 7862. The driven wheel 7863 is rollingly connected to the driving wheel 785.

[0053] The specific implementation method is as follows: during welding, the square greenhouse grid is installed, the top motor 1 is turned on to drive the longitudinal screw 9 to rotate, and the height of the lifting shell 2 is adjusted so that the welding end of the plasma arc welding module 76 is located at the welding point between the grids. During welding, the control side motor 3 drives the transverse screw 12 to rotate, thereby driving the welding mechanism 7 to perform horizontal displacement to achieve linear welding of the grid. During this process, the weld processing wheel 784 can also roll on the weld after the grid is welded. During this process, the multiple processing bumps 787 on the outside of the weld processing wheel 784 can achieve the processing and At the same time, the weld processing wheel 784 can adaptively fluctuate on the uneven weld through the telescopic spring 781. At the same time, when the weld processing wheel 784 rolls on the weld, it can drive the installation shaft 783 and the driving wheel 785 to rotate. The driving wheel 785 can drive the driven wheel 7863 to rotate. The driven wheel 7863 can drive the rotating shaft 7862 and the blade 7861 to rotate synchronously. The rotation of the blade 7861 generates high-speed airflow, which can help the weld processed by the weld processing wheel 784 to quickly cool and form, and at the same time can blow away some solid impurities generated when processing the weld.

[0054] Through this design, stable linear welding of the greenhouse grid can be completed, and the weld can be processed synchronously during welding. Impurities in the weld processing process can also be cleaned, which greatly improves the overall welding quality of the grid, ensures the flatness and firmness of the weld, and improves the actual application effect of the overall equipment.

[0055] A heat radiation plate 75 is rotatably installed on the inner side of the bottom groove 73 via a rotating shaft, and a plurality of heat radiation grooves 710 are arranged on the bottom surface of the heat radiation plate 75. An adsorption magnetic block 79 is fixedly installed on the top surface of the heat radiation plate 75. One end of the adsorption magnetic block 79 is embedded in the inner side of the inner slot 72. An inner magnetic block with a different magnetic pole from the adsorption magnetic block 79 is arranged inside the inner slot 72. A heat expansion block 74 is fixedly installed on the inner wall of one side of the inner slot 72.

[0056] The specific implementation method is as follows: during the welding process, the temperature of the welding area increases. At this time, the heat expansion block 74 in the movable shell 71 can sense the temperature and expand automatically. After the heat expansion block 74 expands, one end of the heat expansion block 74 can produce contact pressure on the adsorption magnetic block 79, pushing the adsorption magnetic block 79 out of the inner slot 72. At this time, the heat radiation plate 75 can be deflected to a vertical state. At this time, the heat dissipated to the outside during the welding process can be reflected to the welding area by the multiple heat radiation grooves 710 of the heat radiation plate 75, which can continuously ensure the high temperature of the welding area and avoid local heat loss in the welding area, thereby stably improving the welding effect of the grid and further improving the application effect of the equipment.

[0057] Working principle: When welding greenhouse grids, first install the greenhouse grids in four directions at the four corners of the first mounting frame 62, and the grid positioning components 61 at the four corners of the first mounting frame 62 can squeeze the four greenhouse grids and piece together the four greenhouse grids into a larger grid;

[0058] The top motor 1 is turned on to drive the longitudinal screw 9 to rotate, and the height of the lifting shell 2 is adjusted so that the welding end of the plasma arc welding module 76 is located at the welding point between the grids. During welding, the control side motor 3 drives the transverse screw 12 to rotate, thereby driving the welding mechanism 7 to move horizontally to achieve linear welding of the grid. During this process, the weld processing wheel 784 can also roll on the weld after the grid is welded. During this process, the multiple processing bumps 787 on the outside of the weld processing wheel 784 can achieve the processing and flattening of the weld. At the same time, the weld processing wheel 784 can The telescopic spring 781 is used to adaptively fluctuate on the uneven weld. At the same time, when the weld processing wheel 784 rolls on the weld, it can drive the installation shaft 783 and the driving wheel 785 to rotate. The driving wheel 785 can drive the driven wheel 7863 to rotate. The driven wheel 7863 can drive the rotating shaft 7862 and the blade 7861 to rotate synchronously. The rotation of the blade 7861 generates high-speed airflow, which can help the weld processed by the weld processing wheel 784 to quickly cool and form, and at the same time, some solid impurities generated when processing the weld can be blown away;

[0059] During the welding process, the temperature of the welding area increases. At this time, the heat expansion block 74 in the movable shell 71 can sense the temperature and automatically expand. After the heat expansion block 74 expands, one end of the heat expansion block 74 can produce contact pressure on the adsorption magnetic block 79, pushing the adsorption magnetic block 79 out of the inner slot 72. At this time, the heat radiation plate 75 can be deflected to a vertical state. At this time, the heat dissipated to the outside during the welding process can be reflected to the welding area by the multiple heat radiation grooves 710 of the heat radiation plate 75, which can continuously ensure the high temperature of the welding area and avoid local temperature loss in the welding area, thereby stably improving the welding effect of the grid;

[0060] After the welding mechanism 7 welds the longitudinal center lines of the four grids, the control motor 64 can be turned on to drive the first mounting frame 62 to rotate 90° to perform another center line welding of the four grids. At the same time, when processing the weld, the processed impurities can leak down through the leakage groove 63 of the first mounting frame 62 to the material guide inclined plate 51. After waiting for a period of time, the side baffle 52 can be opened to carry out centralized processing of impurities.
