Description

Technical Field

[0001] This utility model relates to the field of electric welding equipment technology, specifically to an electric welding device for production of weighing hoppers with protective functions. Background Technology

[0002] A weighing hopper is a type of under-tank weighing equipment. It is a welded product made of metal sheets. During its processing, it needs to be used in conjunction with an electric welding device for weighing hopper production. Electric welding uses the high-voltage arc generated when the positive and negative electrodes are short-circuited at an instant to melt the welding material on the welding rod, so that they can achieve atomic bonding and thus connect the two objects together.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 219026243 U), "This utility model discloses a rapid welding device, including a workbench and a movable base. A suction pipe is fixedly connected to the suction end of a blower, a slag hopper is fixedly connected to one end of the suction pipe, and a slag discharge pipe is fixedly connected to the exhaust end of the blower. A slag collection box is fixedly connected to the surface of the workbench, and the slag collection box is fixedly connected to the slag discharge pipe. An exhaust hole is opened through the surface of the slag collection box, and a door is hinged to the surface of the slag collection box. A placement plate is fixedly connected to the top surface of the workbench. In this rapid welding device, the suction end of the blower generates suction to draw welding slag from the surface of the workbench through the suction pipe and the slag hopper. The welding slag then enters the slag collection box through the suction pipe and the slag discharge pipe. This achieves the goal of facilitating timely cleaning of welding slag on the workbench surface, avoiding the problem of welding slag accumulating on the workbench surface and affecting subsequent welding work. It also facilitates clamping the objects to be welded."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model generates suction through the suction end of the set suction fan, which draws the welding slag from the workbench surface through the slag suction pipe and slag suction hopper. Subsequently, the welding slag enters the interior of the slag collection box through the slag suction pipe and slag discharge pipe. The air outlet on the surface of the slag collection box allows air to circulate inside. In actual use, because the welding head position of this device is fixed, it cannot be well adjusted to meet different welding needs, and interference between devices is likely to occur. At the same time, the fixed clamping position of this device makes it difficult to clamp welding items of different sizes and shapes. Therefore, it is necessary to improve the welding device for production with a weighing hopper with protective function to solve the above problems. Utility Model Content
