[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This includes products made using all processes, including injection molding and blister molding. Plastic is a type of synthetic polymer with plasticity. During the production process, a melting device is typically used to melt the raw materials used to make these products.

[0003] The existing melting device can basically meet the needs of melting plastic raw materials in the production of plastic products. However, when adding plastic raw materials from the feed hopper to the melting device and discharging the melted plastic raw materials from the discharge port to the melting tank, due to the lack of corresponding structure, the plastic raw materials with large size in the initial state are very easy to clog the feed hopper, and the flow rate of the molten plastic raw materials is limited, which makes it very easy to clog the discharge port.

[0004] Based on this, the utility model provides a plastic raw material melting device for producing plastic products. Utility Model Content

[0005] The technical problem solved by the utility model is that the plastic raw materials with large size in the initial state are very easy to block the feed hopper, and the flow rate of the molten plastic raw materials is limited and thus very easy to block the discharge port.

[0010] Furthermore, a discharge control valve is provided on the discharge port.

[0011] Furthermore, main stirring blades are equidistantly arranged on the circumference of the stirring rod and are placed above the spiral blades, and auxiliary stirring blades are equidistantly arranged on the bottom of the main stirring blades.

[0012] Beneficial effects of the utility model:

[0013] Through the drive component, the same motor is used to drive the stirring and anti-blocking component and the crushing component at the same time, saving electricity costs.

[0023] Principle of the utility model

[0024] When in use, the plastic raw material to be melted is added from the feed hopper 4 to the melting tank 1, and the electric heating pipe 18 in the heating sleeve 17 is started to heat the melting tank 1, thereby heating and melting the plastic raw material in the melting tank 1.
