Detailed Implementation
[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model discloses a melting device for modified cross-linked polystyrene material.
[0025] This utility model provides, for example Figure 1-3 The device for melting modified cross-linked polystyrene material shown includes a base plate 1 and a support frame 2 fixedly mounted on the top of the base plate 1. A mounting frame 3 is fixedly mounted on the top of the base plate 1. The mounting frame 3 is a U-shaped frame. Rotating shafts 4 are rotatably mounted on both sides of the mounting frame 3. A melting cylinder 5 is fixedly mounted between the two rotating shafts 4. A cavity is opened on the side of the melting cylinder 5. A heating rod 6 is fixedly embedded in the cavity. The heating rod 6 is spirally wound.
[0026] The support frame 2 has a strip-shaped hole inside, and a movable plate 7 is slidably fitted on the side of the strip-shaped hole. The movable plate 7 has a through hole 21 inside that matches the sliding side of the strip-shaped hole. A stirrer 8 is fixedly installed on the top of the movable plate 7, and the lower end of the stirrer 8 extends into the melting cylinder 5.
[0027] In order to ensure that the stirrer 8 moves upward and separates from the molten cylinder 5, the molten cylinder 5 can be stably driven to rotate, such as... Figure 1-2As shown, the side of the movable plate 7 is provided with a separation drive mechanism and a transmission mechanism for driving the molten cylinder 5 to rotate. The separation drive mechanism includes a drive screw 9, which is rotatably disposed in a slotted hole. A motor 10 is fixedly disposed on the top of the support frame 2. The end of the output shaft of the motor 10 passes through the slotted hole and is fixedly connected to the drive screw 9. The drive screw 9 is threaded inside the movable plate 7. A drive rack 11 is fixedly disposed on the outer wall of the movable plate 7. A first crossbar 12 is rotatably disposed on the upper end of the outer wall of the support frame 2. A circular gear 13 is fixedly sleeved on the wall of the first crossbar 12. The drive rack 11 and the circular gear 13 are connected to the first crossbar 12. The gear 13 is configured to engage with the transmission mechanism, which includes a worm gear 14 and a worm 15. The worm gear 14 is fixedly sleeved with the rotating shaft 4. A second crossbar 16 is rotatably provided at the lower end of the outer wall of the support frame 2. Synchronous pulleys 17 are fixedly sleeved on the walls of both the second crossbar 16 and the first crossbar 12. A synchronous belt 18 is provided for external transmission of the synchronous pulleys 17. Two mounting plates 19 are fixedly provided on the top of the base plate 1. The worm 15 is rotatably positioned between the two mounting plates 19 and engages with the worm gear 14. A bevel gear 20 is fixedly provided at the end of the worm 15 and the second crossbar 16 that is close to each other. The two bevel gears 20 are engaged with each other.
[0028] Working principle: When the melting device for the modified cross-linked polystyrene material is working, the modified cross-linked polystyrene raw material is first added into the melting cylinder 5. The heating rod 6 is energized and heats up the raw material inside the melting cylinder 5, causing the raw material to gradually melt. At the same time, the stirrer 8 is started to stir the molten material to ensure that the material is heated evenly and melted completely.
[0029] When the material has melted and needs to be collected, start the motor 10. The motor 10 drives the drive screw 9 to rotate. Since the drive screw 9 is threadedly engaged with the moving plate 7, the moving plate 7 will slide upward along the strip hole, driving the stirrer 8 to move upward, so that the lower end of the stirrer 8 is pulled out from the melting cylinder 5, realizing the separation of the stirrer 8 from the melting cylinder 5.
[0030] During the upward movement of the moving plate 7, the drive rack 11 on its outer wall moves upward synchronously. The drive rack 11 meshes with the spur gear 13, driving the first crossbar 12 to rotate. The first crossbar 12 drives the second crossbar 16 to rotate through the synchronous wheel 17 and the synchronous belt 18. The second crossbar 16 drives the worm gear 15 to rotate through the bevel gear 20. The worm gear 15 meshes with the worm wheel 14, driving the rotating shaft 4 to rotate, thereby causing the molten cylinder 5 to rotate around the rotating shaft 4.
[0031] When the melting cylinder 5 rotates to the horizontal position of the opening, the motor 10 is turned off. The operator can then reach into the melting cylinder 5 to effectively collect the molten material adhering to the inner wall, reducing material waste. After collection, the motor 10 is restarted in reverse to reset the melting cylinder 5. At the same time, the stirrer 8 is reinserted into the melting cylinder 5 for the next melting operation. The perforation 21 inside the moving plate 7 slides with the side of the strip hole, ensuring the stability of the moving plate 7 as it moves up and down. The heating rod 6 is spirally wound, which improves the heating efficiency and uniformity of the melting cylinder 5.
[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
