[0029] See also Figures 1 to 5A pretreatment device for polystyrene foam material comprises a mixing and stirring component 1, wherein the mixing and stirring component 1 comprises a main body support frame 101, wherein a plurality of fixed rods 102 are fixedly connected inside the main body support frame 101, wherein the upper ends of the plurality of fixed rods 102 are fixedly connected with a fixed mounting ring 103, wherein the upper ends of the fixed mounting ring 103 are fixedly connected with a plurality of sliding rods 104, wherein the middle parts of the plurality of sliding rods 104 are slidably connected with a sliding ring 105, wherein the middle parts of the sliding rods 104 are located between the sliding ring 105 and the fixed mounting ring 103. A buffer spring 106 is provided, the upper end of the sliding ring 105 is fixedly connected to a stirring and mixing barrel 107, the lower end of the stirring and mixing barrel 107 is fixedly connected to a vibration shell 108, the interior of the vibration shell 108 is fixedly connected to a vibration pump 109, the upper end of the main body support frame 101 is rotatably connected to a rotating rod 110, and a plurality of stirring rods are fixedly connected to the middle part of the rotating rod 110, the upper end of the main body support frame 101 is also fixedly connected to a servo motor 111, and the output end of the servo motor 111 is fixedly connected to the upper end of the rotating rod 110.
[0030] In this solution, the polystyrene foam material, the foaming agent and the stabilizer need to be mixed and stirred first. The polystyrene foam material, the foaming agent and the stabilizer need to be poured into the mixing barrel 107 according to a certain ratio, and then the servo motor 111 and the vibration pump 109 are started at the same time. The vibration pump 109 rotates to drive the vibration housing 108 fixedly connected thereto to vibrate.
