Technical Field
[0001] This utility model relates to the field of extruded polystyrene (XPS) board raw material processing technology, specifically to an XPS board raw material screening machine. Background Technology
[0002] Extruded polystyrene (XPS) board is a material widely used in the construction and insulation fields. XPS board has excellent thermal insulation, waterproof performance, and compressive strength. The main raw material of XPS board is polystyrene. During the production process, various auxiliary materials and additives are added. The production process of XPS board requires the use of a screening machine to screen and clean the raw materials.
[0003] There are many types of existing screening machines. Among them, vibrating screens are suitable for screening extruded polystyrene (XPS) board raw materials. They are driven by a motor to rotate an eccentric block, which in turn drives the spring-connected housing and screen to vibrate and achieve screening. However, XPS board raw materials contain impurity particles. During the vibration process, these impurity particles may clog the screen mesh, affecting the screening effect and increasing the difficulty of cleaning the screen. Therefore, we propose an XPS board raw material screening machine. Utility Model Content
[0004] The purpose of this utility model is to provide a screening machine for extruded polystyrene (XPS) board raw materials, in order to solve the problem mentioned in the background art that the XPS board raw materials contain impurity particles, and that these impurity particles can clog the screen mesh during the vibration process, which affects the screening effect of the screen and increases the difficulty of cleaning the screen.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening machine for extruded polystyrene board raw materials, including a screen, a box, a bottom box, and also including an auxiliary component and a cleaning component. The cleaning component is installed inside the box, and the auxiliary component is installed inside the bottom box. When the cleaning component is started, it cleans the impurities clogging the inside of the screen.
[0006] Preferably, the cleaning assembly includes a slider, a sliding frame, a roller, and a conical rod. A symmetrical sliding frame is fixedly connected to the inner wall of the housing. A slider is slidably connected inside the sliding frame. A roller is movably connected to the side of the slider. Equally spaced conical rods are fixedly connected to the surface of the roller. A gear is installed at one end of the roller surface. The gear meshes with a rack at the bottom of the screen. A handle is inserted into the outside of the housing. The other end of the handle is fixedly connected to the slider. A matching inclined groove is formed on the surface of the housing.
[0007] Preferably, the auxiliary components include a rocker arm, a spiral conveying roller, and a movable rod. The movable rod is installed inside the bottom box, and the surface of the movable rod is provided with symmetrical spiral conveying rollers. Both ends of the movable rod extend to the outside of the bottom box, and a rocker arm is installed at the outer end of the movable rod.

The roller 14 is movably connected to the side of the slider 10. The surface of the roller 14 is fixedly connected with equidistant conical rods 15. The conical rods 15 are made of TPU material. A gear 13 is installed at one end of the surface of the roller 14. The gear 13 meshes with the rack 16 at the bottom of the screen 1. A handle 11 is inserted into the outside of the housing 2. The other end of the handle 11 is fixedly connected to the slider 10. The surface of the housing 2 is provided with matching inclined grooves.
[0021] Based on the aforementioned scheme, the bottom of the box 2 is provided with a base 4, and a spring 3 is provided between the box 2 and the base 4. The bottom of the box 2 is connected to the bottom box 5. A motor with an output end connected to an eccentric block is installed on the surface of the bottom box 5. The box 2 is provided with a longitudinal three-layer screen 1.
[0022] A sliding frame 12 is installed on the inner wall of the housing 2 below the top screen 1, which is slidably connected to a slider 10 with a roller 14. The surface of the roller 14 is provided with equidistant tapered rods 15, and the surface of the roller 14 is also provided with gears 13 that mesh with the rack 13 at the bottom of the top screen 1. Holding the handle 11 drives the slider 10 and the roller 14 to slide inside the sliding frame 12. At the same time, under the transmission action of the rack 16 and the gear 13, the roller 14 moves and rotates, causing the tapered rods 15 on the surface of the roller 14 to continuously insert into the mesh of the screen 1, squeezing out the impurity particles that are blocked in the screen 1 to the surface of the screen 1, which facilitates the collection of impurity particles.
[0023] As a further embodiment of this invention, the auxiliary components include a rocker arm 7, a spiral conveying roller 8, and a movable rod 9.

[0024] Inside the bottom box 5, there is a movable rod 9 with symmetrical spiral conveying rollers 8. Rotating the rocker arm 7 drives the movable rod 9 to rotate, and the movable rod 9 drives the spiral conveying rollers 8 to rotate, pushing the material at the bottom of the bottom box 5 into the discharge troughs 6 at both ends of the bottom box 5. This is convenient to operate and also helps to discharge the material at the bottom of the bottom box 6.
[0025] It should be noted that this utility model is a screening machine for extruded polystyrene (XPS) board raw materials. The XPS board raw material is added to the surface of the top screen 1 inside the housing 2. The motor is started, driving the eccentric block to rotate. Supported by the spring 3, the housing 2 vibrates, screening the XPS board raw material. During the screening process, many impurities are filtered by the top screen 1. When impurities clog the top screen 1, the gripping rod 11 drives the slider 10 and roller 14 to slide inside the sliding frame 12. Simultaneously, the rack 16 and... Under the transmission of gear 13, roller 14 moves and rotates, causing the tapered rod 15 on the surface of roller 14 to continuously insert into the mesh of screen 1, squeezing out the impurity particles that are blocked in screen 1 to the surface of screen 1, thus cleaning the impurity particles and facilitating their collection. After the screening operation is completed, the rocker arm 7 is turned to drive the movable rod 9 to rotate, and the movable rod 9 drives the spiral conveyor roller 8 to rotate, pushing the material at the bottom of the bottom box 5 to the discharge troughs 6 at both ends of the bottom box 5 to discharge, which helps to discharge the material at the bottom of the bottom box 6 and makes the discharge efficiency higher.
