An anti-sticking layer 18 is provided on the inner wall of the furnace body 3, and an electric heating wire 13 is provided between the furnace body 3 and the anti-sticking layer 18. When the crushed plastic particles fall into the furnace body 3, the electric heating wire 13 is turned on to heat and melt the plastic particles. The anti-sticking layer 18 can prevent the melted plastic particles from sticking and remaining in the furnace body 3. The anti-sticking layer 18 adopts the most conventional technical means in the prior art. A stirring component is provided inside the furnace body 3. An installation plate 5 is fixedly connected to the top of the furnace body 3. A crushing box 6 is fixedly connected to the top of the installation plate 5. A crushing component is provided in the crushing box 6. A blanking plate 12 is provided on the inner wall of the bottom of the crushing box 6. A feeding port 7 is provided at the top end of the crushing box 6. The plastic particles are poured into the feeding port 7. A base 1 is fixedly connected to the bottom of the furnace body 3. Legs 2 are fixedly connected to the four corners of the bottom end of the base 1. An outlet 19 is provided at the bottom of one side of the furnace body 3 for discharging the melted plastic particles. Support columns 4 are fixedly connected to the four corners of the top end of the base 1. The top ends of the support columns 4 are connected to the installation plate 5. The support columns 4, the installation plate 5, and the crushing box 6 are all provided with blanking holes and are interconnected.

[0030] The crushing component includes a twisting roller 10 located inside the crushing box 6 and rotatably connected to the inner wall of the crushing box 6. Transmission gears 11 are provided at one ends of the twisting rollers 10, and the transmission gears 11 are meshed with each other. A support seat 8 is fixedly connected to one side of the top end of the installation plate 5. A first motor 9 is provided at the top end of the support seat 8. The driving end of the first motor 9 is connected to the other end of one of the twisting rollers 10.

[0031] Specifically, when the first motor 9 is started, the driving end of the first motor 9 drives one of the twisting rollers 10 and the transmission gear 11 to rotate simultaneously. Since the two transmission gears 11 are meshed with each other, the other twisting roller 10 is driven to rotate. When the two twisting rollers 10 rotate towards each other, the large plastic particles are crushed, so as to ensure that the raw materials put down are all small particle polyethylene particles, which are easier to melt during melting.

[0032] The stirring assembly includes a rotating shaft 14 that rotates inside the furnace body 3. A plurality of support plates 15 are fixedly connected to the outer wall of the rotating shaft 14. The other end of the support plate 15 is fixedly connected to a stirring plate 16. The stirring plate 16 is connected to the inner wall of the furnace body 3. A spiral stirring blade 17 is fixedly connected to one side of the stirring plate 16 close to the rotating shaft 14. In the middle of the bottom end of the furnace body 3, a second motor 20 is fixedly connected. The driving end of the second motor 20 is connected to the bottom end of the rotating shaft 14.

[0033] Specifically, by the rotation of the second motor 20, the driving end of the second motor 20 drives the rotating shaft 14 to rotate. Through the connection of the support plate 15, the stirring plate 16 and the spiral stirring blade 17 can be rotated, so as to stir the plastic particles during the heating and melting process. The spiral stirring blade 17 can stir the raw materials at the bottom upward, enabling the raw materials inside to be evenly heated and completely melted, thus improving the melting efficiency.

[0034] Working principle: First, pour the plastic particles into the feeding port 7. Subsequently, the plastic particles will fall between the two stranded rollers 10 inside the crushing box 6. Then start the first motor 9. The driving end of the first motor 9 drives one of the stranded rollers 10 and the transmission gear 11 to rotate simultaneously. Since the two transmission gears 11 are meshed with each other, the other stranded roller 10 is driven to rotate. When the two stranded rollers 10 rotate towards each other, the large - particle plastic particles are crushed. Then, through the blanking plate 12, the crushed plastic particles are introduced into the blanking hole and fall into the furnace body 3. Turn on the heating wire 13 to heat - melt the plastic particles. Subsequently, the second motor 20 rotates. The driving end of the second motor 20 drives the rotating shaft 14 to rotate. Through the connection of the support plate 15, the stirring plate 16 and the spiral stirring blade 17 can be rotated, so as to stir the plastic particles during the heating and melting process, making them completely melted. The melted plastic particles are discharged from the discharge port 19.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
