Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coiled material processing, and particularly relates to a coiled material base joint device. Background Art

[0002] During the production line processing of the waterproof roll base cloth, when the waterproof roll base cloth is about to be used up and the next circle of base cloth is put on, it is necessary to sew it with the tail of the previous roll of base cloth with needle and thread to ensure the continuity of production. The existing technical solution needs to sew manually with needle and thread, and the production line needs to be stopped for a period of time during work, so it has the disadvantages of wasting time and reducing production efficiency.

[0003] For example, a waterproof roll material base fabric joint device described in patent number CN203077630U has upper and lower joint parts arranged on a bracket, and heating plates are arranged on one side of the upper and lower joint parts. The adhesive is first applied to the base fabric joint, and then the two heating plates are relatively dried and firmly bonded, thereby improving production efficiency. Such a setting still requires manual application of the adhesive, and the amount of manual application is difficult to control, and the application is prone to unevenness, which will affect the connection quality of the product. At the same time, the degree of automation is low, which is not suitable for large-scale production and processing needs. Utility Model Content
