Welding device of geogrid ultrasonic welding machine

Abstract

The invention relates to a welding device of a geogrid ultrasonic welding machine, belonging to the technical field of geogrid ultrasonic welding machines. The welding device comprises at least one welding head and an aluminum die head which are matched with each other, wherein the aluminum die head is of an integral structure; the at least one welding head is arranged above the aluminum die head in a corresponding way; the top of each welding head is provided with a lifting mechanism for driving the welding head to move up and down; the top of each lifting mechanism is arranged on a sliding block plate; a sliding connection plate is correspondingly arranged on the sliding block plate; the sliding block plate is in sliding fit connection with the sliding connection plate and is provided with a fixing mechanism for locking the sliding block plate and the sliding connection plate. The aluminum die head is arranged under the welding heads, and each welding head is provided with one lifting mechanism, so that two grid strips at each crossing point on the same straight line can be firmly pressed when the welding device is used, the welding quality is guaranteed, the production efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a welding device for a geogrid ultrasonic welding machine, which belongs to the technical field of geogrid ultrasonic welding machines. Background technique [0002] At present, geogrids are more and more widely used in construction, and the demand has greatly increased. From the surface, the traditional process can no longer meet the demand for the number of geogrids. Therefore, a novel processing technology - geogrid ultrasonic welding machine with Its advantages such as high efficiency, high quality, beautiful appearance and energy saving stand out. [0003] Geogrid ultrasonic welding machine does not add any adhesives, fillers or solvents, nor consumes a large amount of heat when welding geogrids. It has the advantages of simple operation, fast welding speed, high welding strength, and high production efficiency. Its main working principle is: when the ultrasonic wave acts on the contact surface of the thermoplastic gratin...

AI Technical Summary

Problems solved by technology

When this method is used in production, sometimes because the thickness of the grid strips is different, and the distance between the aluminum die head and the welding head is uniform, it will cause two grids at the cross intersection on the same straight line The pressure applied to the bars is not the same

The place with a large thickness will be compacted; the place with a small thickness will not be compacted, and the welding will not be firm, which will affect the welding quality, and the specification of the geogrid is inconvenient to replace
