Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a window screen welding machine. Background Art

[0002] Some fabrics in daily life (such as window screens, curtains, etc.) need to be welded with zippers or buckles to facilitate the fixing of these fabrics through zippers, or installation by clipping the buckles into the corresponding installation ports. Some fabrics on the market are welded with zippers or buckles by welding machines. When welding, the zipper / buckle is usually placed in a preset position, and then the fabric and zipper (or buckle) are aligned, and then the two are welded together by hot melting. The weld edges of fabrics, zippers, and buckles are usually soft, so when welding, workers need to spend more time to align the weld edges, and the work efficiency is not high.

[0003] For example, the curtain adhesive welding machine disclosed in Chinese patent application number: CN202320800877.3. It specifically discloses that "the positioning mechanism includes a lower limit plate, an upper limit plate and a motor assembly, and the motor assembly is arranged on the frame. The lower limit plate is arranged at the output end of the motor assembly, and the motor assembly drives the lower limit plate to move forward and backward on the platform. The upper limit plate is arranged at the front end of the top surface of the lower limit plate and moves with the lower limit plate." The lower limit plate moves forward and backward on the platform, that is, the positioning mechanism can only adjust the relative position (welding position) relationship between the fabric and the adhesive (zipper, buckle edge), but cannot fix the adhesive. At the same time, since the size of the adhesive is usually small, displacement may occur during the welding process, thereby affecting the quality of welding.

[0004] In addition, for different adhesives, the lower limit plate and the upper limit plate cannot be switched automatically, and the degree of automation is not high. Utility Model Content
