The heating and melting device for deep processing of waste plastics includes: a base 1, a middle hole 2 is opened at the top of the base 1, a heating tank 3 is fixedly connected inside the middle hole 2, the heating tank 3 penetrates through the base 1 and extends to the outside of the base 1, a straight fixing block 4 is fixedly connected to the top of the heating tank 3, a linear motor 5 is fixedly connected to the top of the straight fixing block 4, a round block 6 is fixedly connected to one end of the linear motor 5, a short column 7 is fixedly connected to the other side edge of the round block 6, a connecting rod 8 is movably connected to the outside of the short column 7, a feeding pipe 9 is fixedly connected to the top of the heating tank 3, a sieving block 10 is fixedly connected to the top of the feeding pipe 9, a feeding pipe 11 is fixedly connected to the top of the sieving block 10, a sieve opening 12 is opened on the outside of the sieving block 10, the sieve opening 12 penetrates through the sieving block 10 and extends to the outside of the sieving block 10, a sieve plate 13 is slidably connected inside the sieve opening 12, a connecting block 14 is fixedly connected to the outside of the sieve plate 13, a pulling column 15 is fixedly connected to one side of the connecting block 14, the other end of the pulling column 15 is movably connected to the outside of the connecting rod 8, and a rough sliding opening 16 is opened on the outside of the sieve plate 13.
[0023] By installing a feeding pipe 11 at the top of the sieving block 10, the raw materials are put into the sieve plate 13 from the feeding pipe 11. The continuously moving smaller waste plastic particles slide out through the feeding pipe 9 at the bottom of the sieving block 10 and enter the heating tank 3 for melting. The larger waste plastic particles are on the top of the sieve plate 13, and during the continuous linear movement, the larger waste plastic particles vibrate out through the rough sliding opening 16.
[0024] A stirring fixing block 17 is fixedly connected to the top of the heating tank 3, a stirring motor 18 is fixedly connected to the outside of the stirring fixing block 17, a cylinder 19 is fixedly connected to the bottom of the stirring motor 18, stirring blades 20 are fixedly connected to the outside of the cylinder 19, a main runner 21 is fixedly connected to the outside of the cylinder 19, a belt 22 is drivingly connected to the outside of the main runner 21, an auxiliary column 23 is movably connected to the top of the heating tank 3, an auxiliary runner 24 is fixedly connected to the outside of the auxiliary column 23, the other end of the belt 22 is drivingly connected to the outside of the auxiliary runner 24, a rotating tooth 25 is fixedly connected to the bottom of the auxiliary column 23, a circular groove 26 is opened inside the heating tank 3, a transmission rotating circle 27 is slidably connected inside the circular groove 26, the transmission rotating circle 27 is meshed with the rotating tooth 25, a scraping rod 28 is fixedly connected to the bottom of the transmission rotating circle 27, and a scraping plate 29 is fixedly connected to the bottom of the scraping rod 28.
[0025] The bottom cylinder 19 rotates synchronously driven by the stirring motor 18. When the cylinder 19 rotates, the external stirring blades 20 stir the solution inside the heating tank 3 to facilitate the full melting of the waste plastic raw materials inside, avoiding the formation of coagulated lumps due to insufficient melting. The kinetic energy of the rotation of the cylinder 19 is transmitted to the auxiliary column 23 through the belt 22 drive mode. The transmission ring 27 rotates by meshing with the rotating gear 25, driving the scraper 29 to rotate. The curved arc of the scraper 29 can fit the heating pipe for rotation to clean the adhered molten raw materials on the inner wall of the heating tank 3, ensuring the full melting of the raw materials inside the heating tank 3.
[0026] One side of the base 1 is fixedly connected with a side rod 30, and one side of the side rod 30 is fixedly connected with a push handle 31.
[0027] When the push handle 31 is pushed, the external force is transmitted to the base 1 through the fixed connection of the side rod 30 and the base 1, facilitating the movement of the device.
[0028] The bottom of the heating tank 3 is fixedly connected with an outflow pipe 32, and a valve 33 is fixedly connected to the outside of the outflow pipe 32.
[0029] The molten raw materials inside the heating tank 3 are discharged through the outflow pipe 32, and the flow rate is controlled by the valve 33.
[0030] The bottom of the base 1 is fixedly connected with a wheel column 34, and a universal wheel 35 is fixedly connected to the bottom of the wheel column 34.
[0031] The wheel column 34 raises the space between the device and the ground to prevent the bottom of the device from getting damp and rusty, and the universal wheel 35 makes the overall device more flexible in movement.
[0032] The top of the heating tank 3 is fixedly connected with a sliding thick plate 36.
[0033] When the sieve plate 13 moves linearly, larger crushed particles overflow due to vibration and fall into the sliding thick plate 36. The inside of the sliding thick plate 36 is set to be inclined, facilitating the collection of waste plastic particles for secondary processing.
[0034] The working principle of the heating and melting device for deep processing of waste plastics provided by the present utility model is as follows: A linear motor 5 is installed at the top of the heating tank 3. When the linear motor 5 rotates, a round block 6 at one end rotates. A short column 7 is installed at the other edge of the round block 6. A connecting rod 8 is movably connected to the outside of the short column 7. When the short column 7 rotates, the connecting rod 8 moves in an oblique line. A pulling column 15 is installed outside the sieve plate 13, and the other end of the connecting rod 8 is movably connected to the pulling column 15. The oblique line movement is changed to a linear movement through the movable connection method. The linear movement causes the sieve plate 13 to continuously slide inside the sieving block 10. A feeding pipe 11 is installed at the top of the sieving block 10. The raw materials are put into the sieve plate 13 from the feeding pipe 11. The smaller waste plastic particles that are continuously moving pass through the feeding pipe 9 at the bottom of the sieving block 10 and slide out into the heating tank 3 for melting. The larger waste plastic particles are on the top of the sieve plate 13 and are vibrated out through the coarse sliding opening 16 during the continuous linear movement process.
[0035] Compared with the related technology, the heating and melting device for deep processing of waste plastics provided by the present utility model has the following beneficial effects:
[0036] The present utility model provides a heating and melting device for deep processing of waste plastics. By adding a sieving mechanism at the top of the device, the sieving mechanism cooperates with each other through the linear motor 5, the short column 7, the connecting rod 8, the pulling column 15, the sieve plate 13, and the sieving block 10. The connecting rod 8 moves in a straight line during the movement process, continuously pulling the sieve plate 13, and sieving the crushed waste particles on the sieve plate 13. Through the rapid movement, the larger waste particles can stay on the top of the sieve plate 13, and the appropriate waste particles can slide into the heating tank 3 for melting treatment.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
