Description

Technical Field

[0001] This utility model relates to the technical field of plastic melting machines, and in particular to a plastic granule melting device. Background Technology

[0002] Plastics are usually transported and stored in granular form, and these granules need to be melted before plastic products can be manufactured.

[0003] Existing plastic melting machines, such as the Chinese utility model patent CN222096641U, which describes a plastic granule melting device for plastic bag processing, represent a class of prior art. Their main structure includes a melting cylinder and a stirring and scraping structure. The melting cylinder heats and melts the plastic granules, while the stirring and scraping structure stirs the plastic granules and prevents the melted plastic from sticking to the melting cylinder.

[0004] However, the existing technology and equipment still have the following problems when in use: the existing machines are inconvenient for loading and unloading, the machines are not easy to use, and the plastic particles are homogenized by stirring only. When the plastic particles melt, the unmelted particles with lower density are easy to float up, resulting in low heating and melting efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a plastic granule melting device that automatically transports and extrudes plastic granules by setting up an extrusion conveying device and a melting device, thereby improving the ease of use of the machine. Furthermore, by setting up an extrusion conveying device and a melting device, the plastic granules are stirred and pressure is applied to the plastic granules during transport, so that all the granules melt together, thereby improving the heating and melting efficiency.

[0006] This utility model discloses a plastic granule melting device, including a machine body; it also includes an extrusion conveying device, a melting device, an electric heater, and a crushing device. The extrusion conveying device is installed on the machine body, and the melting device and the crushing device are both installed on the extrusion conveying device. The electric heater is installed on the melting device and the machine body. The machine body provides support. The extrusion conveying device extrudes and transports the plastic granules. The melting device and the electric heater work together to melt and transport the plastic granules. The crushing device crushes larger plastic granules.

[0007] Preferably, the body includes multiple support seats, a base plate, and a bracket, with the base plate mounted on top of the multiple support seats and the bracket mounted on top of the base plate, providing support.

The motor is fixedly mounted at the front end of the reducer and provides power to the auger through the reducer. The motor provides power to drive the auger to rotate and transport the plastic granules.

[0009] Preferably, the melting device includes a melting cylinder, a second auger, a second reducer, and a second motor. The melting cylinder is fixedly installed at the bottom end of the discharge port of the conveying cylinder. A second inlet is provided at the connection between the melting cylinder and the conveying cylinder.

The second reducer is fixedly installed at the rear end of the melting cylinder and is rotatably connected between the melting cylinder and the second auger. The second motor is fixedly installed at the rear end of the second reducer and provides power to the second auger through the second reducer. The second motor provides power to drive the second auger to rotate, and the rotation of the second auger transports the plastic granules.

[0010] Preferably, the diameter of the first auger is larger than the diameter of the second auger; the larger diameter first auger can squeeze more plastic particles into the melting cylinder when rotating, while the smaller diameter second auger can slow down the discharge speed of the molten plastic. The cooperation of the first and second augers can reduce the air bubbles contained in the molten plastic and improve the quality of the finished product. The gradually tightening discharge port second increases the pressure on the molten plastic, reduces the air bubbles contained in the molten plastic, and improves the quality of the finished product.

[0011] Preferably, the electric heater is fixedly fitted onto the outer end of the melting cylinder, and the electric heater is fixedly mounted on the bracket; the electric heater heats and melts the plastic inside the melting cylinder.

[0012] Preferably, the crushing device includes a crushing box, a reducer, a motor, two crushing rollers, and two gears. The crushing box is fixedly installed at the top of the conveying cylinder. A discharge port is provided at the connection between the crushing box and the conveying cylinder, and a feed port is provided at the top of the crushing box.
