Description

Technical Field

[0001] The utility model relates to the field of gluing garbage bags, in particular to a device for spraying and gluing the seams of degradable garbage bags. Background Art

[0002] Garbage bags, as the name suggests, are bags for garbage. This small bag brings great convenience to thousands of households, provides important protection for environmental protection, and is even conducive to garbage recycling and classification. However, garbage bags are mainly made of plastic, which is extracted from petroleum. Moreover, it takes about 200 years for garbage bags to rot when buried underground, and they seriously pollute the soil. If they are incinerated, harmful smoke and toxic gases will be produced, which will pollute the environment for a long time. When producing garbage bags, it is necessary to glue the seams of the garbage bags.

[0003] China's authorized announcement number is CN215096245U, a kind of seam spraying and gluing equipment for biodegradable garbage bags. After the liquid glue of the garbage bag is applied to the seams, it is immediately cooled to effectively prevent the glue from sticking to other garbage bags or equipment, causing blockage of the assembly line and causing safety accidents. After applying the glue, the garbage bag is squeezed to fully bond the seams of the garbage bag, effectively avoiding the problem of improper bonding of the seams of the garbage bag causing product leakage.

[0004] There are still certain shortcomings in use: the garbage bags cannot be tightened when gluing them, and the garbage bags will have wrinkles during gluing, which will reduce the quality of gluing the garbage bags, resulting in poor gluing effects and dead corners for gluing, which limits the practicality of the gluing equipment. At the same time, when gluing the garbage bags, the content of the remaining glue in the glue applicator cannot be monitored in real time, and when the glue gradually decreases, it cannot be adjusted in time, which will also cause the continuity of the feeding equipment during use.

[0005] Therefore, in view of the above problems, a seam spraying and gluing device for degradable garbage bags is proposed. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art, the garbage bags cannot be stretched tightly when gluing them. Since the garbage bags are wrinkled during gluing, the quality of gluing the garbage bags will be reduced, resulting in poor gluing effect of the garbage bags and dead corners of gluing, which limits the practicality of the gluing equipment. At the same time, when gluing the garbage bags, the content of the remaining glue in the glue applicator cannot be monitored in real time. When the glue gradually decreases, it cannot be adjusted in time, which will also cause continuity problems of the feeding equipment during use. The utility model proposes a seam spraying gluing equipment for degradable garbage bags.
