Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing equipment, in particular to a hot melt adhesive compound machine with a drying structure. Background Art

[0002] A compound machine is a device used to bond two sides or more than two layers of fabric together through adhesive to form a composite multi-layer fabric.

[0003] The existing hot melt adhesive laminating machine sprays hot melt adhesive powder between two groups of cloth, and then melts the hot melt adhesive by hot pressing to bond the two groups of cloth. When the bonded cloth is being conveyed, it takes a certain amount of time for the hot melt adhesive to solidify, and the solidification of the hot melt adhesive depends on the thickness of the applied adhesive. When the hot melt adhesive solidifies too slowly, it will be inconvenient for personnel to collect the bonded cloth during production, which will affect people's use. Moreover, the hot melt adhesive laminating machine generally sprays hot melt adhesive powder between two groups of cloth, and when the hot melt adhesive powder is sprayed on the bottom cloth surface, it is easy for the hot melt adhesive powder sprayed at the junction of the nozzle to accumulate on some positions of the cloth, thereby causing the hot melt adhesive powder to accumulate on some positions of the cloth surface, which will then be inconvenient for the hot melt adhesive powder to melt and bond evenly on the cloth surface, which will be inconvenient for people to use.

[0004] The existing Chinese patent with announcement number CN218228261U discloses a hot melt adhesive laminating machine with a drying structure, including an operating table; a glue spraying mechanism is installed on the top of the operating table, an auxiliary mechanism is installed on the back of the glue spraying mechanism, a laminating mechanism is installed on the side of the top of the operating table close to the auxiliary mechanism, and a drying mechanism is installed on the side of the top of the operating table away from the laminating mechanism.

[0005] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device dries the composite cloth by passing it through a drying mechanism, but the drying mechanism is relatively long and inconvenient to pass through the composite cloth, and needs to be improved; therefore, a hot melt adhesive laminating machine with a drying structure is proposed to address the above-mentioned problems.
