Description

Technical Field

[0001] The utility model relates to the field of auxiliary devices for producing thermal insulation boards, in particular to a board edge gluing tool for a vacuum negative pressure platform. Background Art

[0002] Insulated trucks are special vehicles used for transporting fresh goods. In order to prevent the temperature inside the car from changing significantly due to the influence of the outside temperature, the car body is required to have good thermal insulation performance. The insulated truck compartment is structurally equipped with thermal insulation panels to reduce heat exchange between the inside and outside of the car. Vacuum negative pressure insulation panels are the main component of the compartment body of the above-mentioned insulated truck. According to different usage requirements, vacuum negative pressure insulation panels can be divided into single-layer insulation panels and multi-layer insulation panels.
