[0002] The mixing temperature of low-temperature adhesives is usually low to adapt to their application requirements in low-temperature environments. Generally speaking, the mixing temperature range of low-temperature adhesives is between -15°C and room temperature (about 25°C). The specific mixing temperature should be determined according to the adhesive formula, raw material properties and production process requirements. In the prior art, low-temperature adhesives are mixed by setting a cooling mechanism outside the mixing barrel. However, when a cooling mechanism is set outside the mixing barrel, not only is the cooling area inside the mixing barrel not uniform enough, but the low-temperature adhesive on one side of the mixing barrel cannot be quickly cooled. For this reason, this application proposes a mixing device for low-temperature adhesives for cartons to solve the above problems. Utility Model Content
