Technical Field

[0002] Spring sheaths can effectively protect mechanical parts from damage caused by wear, vibration, corrosion and other factors, thereby extending the service life of mechanical parts. During production, the sheath and the spring are connected by glue. Existing spring sheath glue coating machines, such as a spring sheath glue coating mechanism disclosed in application number CN201721763959.6, can quickly, stably and evenly coat the inner side of the spring sheath with hot melt adhesive. Compared with manual coating of hot melt adhesive, the thickness and width of the glue coating are improved, the gluing quality of the spring sheath is improved, and the cost of the hot melt adhesive in the sheath is saved.

[0003] However, in the actual production process, the sizes of spring sleeves are different, and the sizes of installation grooves required for gluing and fixing are also different. The installation groove structure of the existing spring sleeve gluing machine is fixed and cannot adapt to the installation of spring sleeves of different models. The method of replacing different molds is cumbersome and inefficient. In particular, a large number of molds of various models are required, which is costly and occupies a large space. Therefore, we propose a spring sleeve gluing machine to solve the above problems. Utility Model Content
