[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figures 1 to 6 , In the utility model: A new type of galvanized sheet stitch welding device, including a base 1, a welding mechanism 2 is provided on the top of the base 1, an electric push rod 3 fixedly connected to the top of the base 1 is inserted, a lifting plate 4 is fixedly connected to the top of the electric push rod 3, a down-pressure cover 5 is fixedly connected to the top of the lifting plate 4, a cavity 6 is provided on the lifting plate 4, the shape of the cavity 6 is cylindrical, an air inlet 7 and an air outlet 8 are provided on the inner wall of the cavity 6, an activated carbon layer 9 is fixedly connected to the inner wall of the air outlet 8, a rotating block 10 is rotatably connected to the inner wall of the cavity 6, a motor 11 is embedded in the inner bottom wall of the cavity 6, the output shaft of the motor 11 is fixedly connected to the rotating block 10, a concave hole 12 is provided on the rotating block 10, a fan 13 is installed on the inner wall of the concave hole 12, and a ventilation hole 7 is provided on the inner top wall of the concave hole 12. Hole 14, a square groove 15 is provided on the lifting plate 4, and a circular hole 16 connected to the through hole 14 is provided on the inner wall of the square groove 15, and an electric heating plate 17 is installed on the inner wall of the square groove 15. Two air grooves 18 are provided on the inner wall of the square groove 15, and the two air grooves 18 are arranged in an eight-shaped shape; the welding mechanism 2 includes a bracket 201, the front of the bracket 201 is fixedly connected to the base 1, the top of the bracket 201 is inserted with an electric push rod 202 fixedly connected thereto, the bottom end of the electric push rod 202 is fixedly connected to a square plate 203, and the bottom of the square plate 203 is slidably connected to a slider 204, the front of the square plate 203 is inserted with an electric push rod 3 205 fixedly connected thereto, one end of the back of the electric push rod 3 205 is fixedly connected to the slider 204, and a welding head 206 is installed at the bottom of the slider 204.

[0029] After the galvanized sheet is welded, the two galvanized sheets are first placed on the top of the base 1 and the top of the lifting plate 4 respectively, and then the position of the two galvanized sheets to be welded is aligned with the welding head 206, and the motor 11 is started. The motor 11 will drive the rotating block 10 to rotate. During the rotation of the rotating block 10, the direction of the concave hole 12 will be changed until the concave hole 12 is aligned with the air inlet hole 7. At this time, the rotating block 10 will close the air outlet hole 8, and the user turns on the fan 13. The fan 13 will draw air into the concave hole 12 through the air inlet hole 7 and enter the square groove 15 from the through hole 14 and the circular hole 16. Then the air will be ejected from the two air grooves 18. After being ejected, the air will blow towards the two galvanized sheets, thereby blowing off the dust and impurities on the two galvanized sheets, thereby cleaning the galvanized sheets. During this process, the user turns on the electric heating plate 17, and the electric heating plate 17 will heat the air. The heated air will be blown towards the surface of the galvanized sheet and will Preheating the surface can reduce the cooling rate of galvanized sheet during welding. Since the base metal of the galvanized sheet (such as iron) may form a hard and brittle structure when cooled rapidly, preheating can make the weld and heat-affected zone cool down more slowly during the cooling process, reduce the formation of this hard and brittle structure, thereby improving the toughness and strength of the weld joint. Preheating helps to reduce the generation of pores and slag inclusions during galvanized sheet welding. Preheating can make the oil, moisture and other impurities on the surface of the galvanized sheet partially volatilize or decompose before welding, reducing the possibility of these impurities mixing into the molten pool during welding. After completing the cleaning and preheating treatment of the galvanized sheet, the user turns on the electric push rod 3 to drive the lifting plate 4 to descend. The lifting plate 4 will then drive the galvanized sheet to contact the galvanized sheet on the top of the base 1. Then, as the lifting plate 4 descends, the downward pressure cover 5 on the lifting plate 4 will squeeze the top galvanized sheet, so that the top galvanized sheet is pressed tightly against the bottom galvanized sheet, thereby completing the clamping and fixation of the galvanized sheet.

[0030] After completing the positioning of the galvanized sheet, the user first turns on the electric push rod 202 to indirectly drive the welding head 206 to descend until the welding head 206 moves to the welding point between the two galvanized sheets. Then, the welding head 206 can be controlled to weld the galvanized sheet. During the process, the user turns on the electric push rod 3 205 to drive the slider 204 to move and change the position of the welding head 206, thereby completing the welding processing of the galvanized sheet.

[0031] Before welding, the user turns on the motor 11 to drive the rotating block 10 to rotate counterclockwise ninety degrees. At this time, the concave hole 12 will be aligned with the air outlet 8, and the fan 13 will be turned on in the reverse direction. At this time, the fan 13 will exhaust air in the reverse direction. The air on the top of the base 1 will enter the square groove 15 from the air groove 18 and then pass through the circular hole 16 and the through hole 14 into the concave hole 12. During the welding process of galvanized sheet metal, a large amount of harmful gas will be generated by welding. The harmful gas will be sucked into the concave hole 12, and then the harmful gas will enter the air outlet 8. The activated carbon layer 9 in the air outlet 8 will adsorb the harmful substances in the air, thereby effectively preventing the harmful gas from polluting the working environment.

[0032] See also Figure 1 、 2 , 4 and 5, wherein: the front of the lifting plate 4 is interspersed with a filter plate 19 slidably connected thereto, and the outer side of the filter plate 19 is in contact with the inner wall of the air outlet 8.

[0033] In the present invention, the filter plate 19 can filter impurities such as dust in harmful gases, effectively reducing the pollution of the activated carbon layer 9 by dust impurities, thereby increasing the service life of the activated carbon layer 9.

[0034] See also Figure 5 , wherein: the bottom of the pressing cover 5 and the top of the base 1 are fixedly connected with positioning bars 20, and the two positioning bars 20 are respectively located on the right part of the pressing cover 5 and the right side of the lifting plate 4.

[0035] In the present invention, the provision of the positioning strip 20 can help the user to position the galvanized sheet, thereby improving the practicality of the device.

[0036] See also Figure 1 , wherein: the front of the base 1 is fixedly connected to a controller 21 for controlling the opening and closing of the electric push rod 1 3, the motor 11, the fan 13, the electric heating plate 17, the electric push rod 2 202 and the electric push rod 3 205. The setting of the controller 21 can facilitate the user to control the opening and closing of the electric push rod 1 3, the motor 11, the fan 13, the electric heating plate 17, the electric push rod 2 202 and the electric push rod 3 205.

[0037] See also Figure 4 , wherein: the bottom of the lifting plate 4 is fixedly connected to two positioning rods 22, and the bottom ends of the two positioning rods 22 are inserted into the base 1 and slidably connected thereto.

[0038] In the present invention, the positioning rod 22 can limit the upward and downward movement of the lifting plate 4, thereby improving the practicality of the device.
