Description

Energy-efficient hot melt adhesive machine

Technical Field

The utility model relates to a hot melt adhesive equipment technical field specifically is a high-efficient energy-conserving hot melt adhesive machine.

Background

Hot melt adhesives, also known as hot melt adhesives, are generally formed by melting thermoplastic materials (mainly comprising thermoplastic resins) through a hot melt adhesive machine, and are widely applied to the industries of sanitary products (such as paper diaper packaging), non-woven fabric compounding and packaging (carton packaging and cigarette case packaging). Thermoplastic materials, for example, are available in large quantities in solid form, such as granules, candy, etc., and are converted to a molten, softened, flowable liquid state within the heating cylinder of the hot melt adhesive machine. The melted liquid hot melt adhesive can be transported to a coating device or a spray gun by a pressure device (such as a pump) of a hot melt adhesive machine, for example, to glue or spray the substrate.

The heating cylinder of the hot melt adhesive machine, which serves as a container for the molten thermoplastic material (and also for containing the molten hot melt adhesive), is typically of a generally grooved configuration. The wall of the channel-type heating cylinder comprises a bottom wall and a side wall arranged around the bottom wall, and an electric heating pipe is usually arranged below the bottom wall. When the hot melt adhesive machine works, firstly, the thermoplastic material in a solid form is placed in the heating cylinder, then the heating device is started, the heat of the heat heating pipe is transferred to the solid thermoplastic material through the wall surface, particularly the bottom wall, so that the solid thermoplastic material is heated and melted into the liquid hot melt adhesive.

The melting process of solid thermoplastic materials is not uniform, especially when the amount of solid thermoplastic material in the heating cylinder is high. Specifically, the solid thermoplastic material in contact with the wall surface, particularly the bottom wall, of the heating cylinder is first heated to melt into a liquid hot melt adhesive, and the unmelted solid thermoplastic material polymerizes to form a shape resembling an "iceberg" and floats in an area where the temperature of the liquid hot melt adhesive is low, gradually melting by receiving the heat transferred by the liquid hot melt adhesive. In order to ensure the gluing or glue spraying quality of the hot melt glue machine, the gluing or glue spraying work of the hot melt glue machine is started after the solid thermoplastic material added at one time in the heating cylinder is basically completely melted.

Because the heat transfer rate of the liquid hot melt adhesive is low, the temperature rise speed of the area with low temperature of the liquid hot melt adhesive is slow. When more solid thermoplastic materials are put into the heating cylinder at one time, a relatively long time is often needed to melt the solid thermoplastic materials basically and completely, and the melting efficiency is low. Therefore, on one hand, the hot melt adhesive machine has high power consumption and high use cost, and on the other hand, the long-time heating also easily causes the carbonization phenomenon of the hot melt adhesive.

Based on this, the utility model designs an energy-efficient hot melt adhesive machine to solve above-mentioned problem.
