Technical Field

[0001] This utility model relates to the field of EPS polystyrene board technology, specifically a mixing device for EPS polystyrene board production. Background Technology

[0002] Polystyrene board, also known as polystyrene foam board or EPS board, is a protective layer used as a waterproofing layer. It is a white solid with a fine closed-cell structure, made from expandable polystyrene beads containing a volatile liquid foaming agent, which are pre-expanded by heating and then molded in a mold. The production of EPS polystyrene board requires a mixing device to stir the raw materials. The existing technology is authorized by publication number CN 221622679. U's patent discloses a mixing device for EPS polystyrene board production, including a mounting frame. A vibration component is fixedly connected to the surface of the mounting frame. The vibration component includes multiple springs, a mixing tank, a first motor, and an eccentric wheel. A lifting component is fixedly connected to the surface of the mounting frame. The lifting component includes multiple slide rods, a lifting plate, and two electric push rods, which cause the mixing tank to vibrate, thereby driving the raw material particles in the mixing tank to vibrate and displace. At the same time, by setting a stirring component, the stirring shaft drives multiple stirring blades to stir and mix the raw material particles, thereby improving the mixing effect. However, during use, there are disadvantages such as high-density materials settling at the bottom of the mixing tank and not being able to be stirred, and the stirring direction is unidirectional, thus there is still room for improvement.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This embodiment provides a technical solution: a mixing device for EPS polystyrene board production, including a frame 1 and a drive unit 9;

[0020] Frame 1: A mixing tank 2 is rotatably connected to its center. Frame 1 provides support for other components. Inside the mixing tank 2, a support column 3 is located at the right end of a support shell 4. Both ends of the support shell 4 are rotatably connected to stirring racks 5. During the rotation of the mixing tank 2, it will invert. Simultaneously, the mixing tank 2 will drive the stirring racks 5 to rotate around the rotation axis of the mixing tank 2 via the support column 3 and support shell 4. Each of the two stirring racks 5 has a bevel gear 8 at one end inside the support shell 4. A fixed shaft 6 is located at the upper right end of the frame 1. The left end of the fixed shaft 6 extends into the support shell 4 and has a bevel gear 7. Both bevel gears 8 mesh with bevel gear 7. The axis of bevel gear 7 coincides with the rotation axis of the mixing tank 2. The two bevel gears 8 rotate around bevel gear 7, thereby causing the bevel gears to... Wheel 2 8 drives the mixing frame 5 to rotate. Two bevel gears 2 8 are symmetrically distributed, so the two mixing frames 5 rotate in opposite directions. The mixing frame 5 mixes the raw materials that are flipped up and down. A controller 10 is provided on the right side of the frame 1. The input end of the controller 10 is electrically connected to an external power source. Rectangular holes 11 are opened in the middle of the mixing blades at the end of the mixing frame 5. The rectangular holes 11 facilitate the passage and dispersion of raw materials and have a good mixing effect. The feed inlet 13 is provided at the material outlet at the upper end of the frame 1. A valve 14 is connected in series in the middle of the feed inlet 13. When the valve 14 is opened, the EPS polystyrene board raw material is added into the feed inlet 13 and then enters the mixing tank 2. A counterweight plate 12 is provided at the lower end of the mixing tank 2. The counterweight plate 12 balances the weight of the upper and lower ends of the mixing tank 2 and improves the stability of the rotation of the mixing tank 2.

[0021] Drive unit 9: Used to drive the rotation of mixing tank 2. Drive unit 9 includes worm gear 91, worm 92 and motor 93. Worm gear 91 is located at the left end of mixing tank 2. Worm 92 is rotatably connected to the left side of frame 1. Worm 92 is meshed with worm gear 91. Motor 93 is located at the left rear end of frame 1. The output shaft of motor 93 is fixedly connected to the rear end of worm 92. The input end of motor 93 is electrically connected to the output end of controller 10.

Protective shell 94 is located on the left side of frame 1. Worm gear 91 and worm 92 are both located inside protective shell 94. A circular hole corresponding to the output shaft of motor 93 is opened on the rear side of protective shell 94. Protective shell 94 provides protection for internal components to prevent dust from affecting the normal operation of worm 92 and worm gear 91.

[0022] The working principle of the mixing device for EPS polystyrene board production provided by this utility model is as follows: During use, valve 14 is opened, and the EPS polystyrene board raw material is added into the inlet / outlet hopper 13 and then into the mixing tank 2. After addition is complete, valve 14 is closed, and controller 10 is activated. Motor 93 operates, and the output shaft of motor 93 drives worm gear 92 to rotate. Worm gear 92 drives mixing tank 2 to rotate at low speed via worm wheel 91. During the rotation of mixing tank 2, it will rotate up and down. Simultaneously, mixing tank 2 will drive stirring frame 5 to rotate around the rotation axis of mixing tank 2 via support column 3 and support shell 4. At the same time, the bevel gear... The axis of the first gear 7 coincides with the rotation axis of the mixing tank 2. The two bevel gears 8 rotate around the first gear 7, which in turn drives the mixing frame 5 to rotate. The two bevel gears 8 are symmetrically distributed, and the two mixing frames 5 rotate in opposite directions. The mixing frame 5 mixes the raw materials that are flipping up and down. At the same time, the mixing blades at the end of the mixing frame 5 are provided with rectangular holes 11 in the middle, which facilitates the passage and dispersion of the raw materials and has a good mixing effect. After the mixing is completed, when the inlet and outlet hopper 13 rotates to the lower end, the motor 93 of the control controller 10 stops running and the valve 14 is opened to discharge the material.
