Description

Technical Field

[0001] This utility model relates to the field of foam plastic processing technology, specifically a foam plastic raw material heating device. Background Technology

[0002] Foamed plastics are a type of polymer material formed by dispersing a large number of gas micropores in solid plastic. They are lightweight, heat-insulating, sound-absorbing, and shock-absorbing, and their dielectric properties are superior to those of the matrix resin, making them widely used.

[0003] Foamed plastics need to be processed into different shapes. Generally, the foamed plastic raw material is heated to a viscous state at high temperature and then shaped by a molding device.

[0004] In the prior art, heating of foamed plastic raw materials is often achieved by installing a heating device on the wall of a heating cylinder. However, in the prior art, the heating device is located on the wall of the heating cylinder, resulting in a higher temperature for the foamed plastic raw material near the heating cylinder, while the temperature is lower in the middle of the heating cylinder, which is further away from the heating device. This fails to provide uniform heating of the raw material within the heating cylinder, affecting the overall heating effect of the foamed plastic raw material. Therefore, there is room for improvement in the prior art. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for foam plastic raw materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heating device for foamed plastic raw materials includes a heating cylinder; a rotating shaft is rotatably mounted at the top of the heating cylinder, and a rotating frame is mounted at the bottom of the rotating shaft. Multiple sliding grooves are provided on the rotating frame and are arranged in a ring at intervals. A limiting rod is fixedly installed within each sliding groove, and a limiting slider is slidably mounted on the limiting rod and slidably connected to the sliding groove. A stirring rod is mounted at the bottom of the limiting slider, and a heating wire is disposed within the stirring rod. A rotating component is provided on the rotating frame, and a swinging component is connected to the rotating component. The rotating component drives the swinging component, and the swinging component drives the limiting slider to reciprocate along the limiting rod, thereby changing the position of the stirring rod.

[0008] As a further embodiment of this utility model: a motor is installed on the top of the heating cylinder, and the output end of the motor is connected to the top of the rotating shaft.

[0009] As a further improvement of this utility model: feeding hoppers are provided on both sides of the top of the heating cylinder, and a discharge pipe is provided at the bottom of the heating cylinder.

[0010] As a further improvement of this utility model, the outer wall of the stirring rod is provided with a plurality of equally spaced stirring blades.

[0011] As a further embodiment of this utility model: the rotating component includes multiple brackets arranged in a ring at intervals on the outer wall of the rotating frame, a drive shaft is rotatably mounted on the bracket, a gear disk is mounted on the drive shaft, two fixed rods are mounted on the top wall of the heating cylinder, and fixed gears are mounted at the bottom of the fixed rods, the fixed gears meshing with the gear disk.

[0012] As a further embodiment of this utility model: the swing component includes a sliding column installed at the bottom of the gear disk and located at the eccentric position, and a swing frame is installed on the top of the limiting slider, with the swing frame slidably connected to the sliding column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When heating foam plastic raw materials, this utility model drives the rotating shaft to rotate, which in turn drives the rotating frame to rotate. When the rotating frame rotates, it simultaneously drives the stirring rod to rotate inside the heating cylinder. The stirring rod agitates the raw materials inside the heating cylinder, and the heating wire heats the stirring rod, thus heating the foam plastic raw materials inside the heating cylinder. Furthermore, the rotating component can drive the swinging component to move the limiting slider back and forth along the limiting rod, thereby continuously changing the position of the stirring rod.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Please see Figures 1-3 A heating device for foamed plastic raw materials includes a heating cylinder 1; a rotating shaft 4 is rotatably mounted at the top of the heating cylinder 1, and a rotating frame 5 is mounted at the bottom of the rotating shaft 4. Multiple sliding grooves 6 are provided on the rotating frame 5 and are arranged in a ring at intervals. A limiting rod 7 is fixedly installed in each sliding groove 6, and a limiting slider 8 is slidably mounted on the limiting rod 7 and slidably connected to the sliding groove 6. A stirring rod 9 is mounted at the bottom of the limiting slider 8, and a heating wire 10 is disposed inside the stirring rod 9. A rotating component is provided on the rotating frame 5, and a swinging component is connected to the rotating component. The rotating component drives the swinging component, and the swinging component drives the limiting slider 8 to reciprocate along the limiting rod 7, thereby changing the position of the stirring rod 9.

[0020] When heating the foam plastic raw material, the rotating shaft 4 is driven to rotate, which in turn drives the rotating frame 5 to rotate. The rotating frame 5 simultaneously drives the stirring rod 9 to rotate inside the heating cylinder 1. The stirring rod 9 agitates the raw material inside the heating cylinder 1, ensuring thorough and uniform mixing. The stirring rod 9 is heated by the heating wire 10, thus heating the foam plastic raw material inside the heating cylinder 1. During the rotation of the rotating frame 5, a rotating component is driven, which in turn drives a swinging component to move the limiting slider 8 back and forth along the limiting rod 7. This continuously changes the position of the stirring rod 9, causing it to move closer to or further away from the axis of the rotating shaft 4. This alters the heating radius of the stirring rod 9 on the foam plastic raw material, ensuring thorough and uniform heating of the material inside the heating cylinder 1. This avoids areas of low temperature due to a fixed heat source location, resulting in better performance.

[0021] A motor 19 is installed on the top of the heating cylinder 1. The output end of the motor 19 is connected to the top of the rotating shaft 4. The rotating shaft 4 is driven to rotate by the motor 19, which in turn drives the rotating frame 5 to rotate, so that the stirring rod 9 can rotate and stir inside the heating cylinder 1 and heat the foam plastic raw material.

[0022] The heating cylinder 1 is provided with feeding hoppers 2 on both sides of the top for feeding foam plastic raw materials. The foam plastic raw materials can be put into the heating cylinder 1 through the feeding hoppers 2. The heating cylinder 1 is provided with a discharge pipe 3 at the bottom for discharging the heated foam plastic raw materials.

[0023] The outer wall of the stirring rod 9 is provided with a plurality of equally spaced stirring blades 11. The stirring blades 11 can stir the foam plastic material in the heating cylinder 1, so that the foam plastic material is fully mixed in the heating cylinder 1, and the stirring rod 9 can fully and evenly heat the foam plastic material.

[0024] The rotating component includes multiple brackets 12 arranged in a ring on the outer wall of the rotating frame 5. A drive shaft 13 is rotatably mounted on the bracket 12, and a gear disk 14 is mounted on the drive shaft 13. Two fixed rods 17 are mounted on the top wall of the heating cylinder 1. Fixed gears 18 are mounted on the bottom of the fixed rods 17. The fixed gears 18 mesh with the gear disk 14. During the rotation of the rotating frame 5, the brackets 12 will rotate together, causing the gear disk 14 connected to the drive shaft 13 to also revolve. Since the fixed gears 18 are fixedly installed, the revolving gear disk 14 will also rotate on its own axis, thereby driving the swing component to drive the limiting slider 8 to slide back and forth along the limiting rod 7, thereby continuously changing the position of the stirring rod 9.

[0025] The swinging component includes a sliding column 16 installed at the bottom of the gear disk 14 and located at the eccentric position. A swing frame 15 is installed on the top of the limiting slider 8. The swing frame 15 is slidably connected to the sliding column 16. When the gear disk 14 rotates, it will drive the swing frame 15 to move through the sliding column 16, so that the limiting slider 8 slides back and forth along the limiting rod 7, thereby continuously changing the position of the stirring rod 9. This allows the heated stirring rod 9 to fully and evenly heat the foam plastic raw material in the heating cylinder 1, avoiding areas with low temperatures due to the fixed position of the heat source, resulting in better performance.

[0026] In this invention, when heating foam plastic raw materials, the rotating shaft 4 is driven to rotate, which in turn drives the rotating frame 5 to rotate. The rotating frame 5 simultaneously drives the stirring rod 9 to rotate inside the heating cylinder 1. The stirring rod 9 agitates the raw materials inside the heating cylinder 1, and the heating wire 10 heats the stirring rod 9, thus heating the foam plastic raw materials inside the heating cylinder 1. Furthermore, the rotating component drives the swinging component to move the limiting slider 8 back and forth along the limiting rod 7, continuously changing the position of the stirring rod 9. This ensures that the heated stirring rod 9 can fully and evenly heat the foam plastic raw materials inside the heating cylinder 1, avoiding areas with low temperatures due to a fixed heat source location, resulting in better performance.
