[0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration, and repair; according to the classification of generation sources, construction waste can be divided into engineering slag Soil, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste Metal, waste bamboo and wood, etc.; construction waste will cause environmental pollution, so the recycling of construction waste has become a problem that people should consider now; in the existing waste plastic recycling molding process, waste plastic will be recycled into the barrel for secondary processing. Melting to form raw materials, but the sinking speed of waste plastics is slow during the melting process, which affects the raw material supply efficiency of the molding machine and affects the productivity of the molding machine;
[0003] For example, a Chinese patent with the application number CN201920049898.X discloses a recycling molding machine for renewable resources, including a feeding adjustment device, an injection plunger, a mold and a body, and a feeding adjustment device is fixed above the body. The feeding adjustment device is connected to the hopper through the feeding rod, the hopper is connected to the barrel through the pipeline, and the outer side of the barrel is provided with a fixing fixture, and the fixing fixture is fixed between the feeding pipe and the fixed plate of the fixed mold. The left end of the barrel is provided with an injection plunger, the right side of the barrel is equipped with a mold, and the mold and the barrel are provided with a fixed mold fixed plate, and the fixed mold fixed plate and the movable mold fixed plate on the right side of the mould. The mold clamping device is welded and fixed on the right side of the movable mold fixing plate, and the mold clamping device is connected with the mold clamping hydraulic cylinder, and a recovery box is arranged under the mold; this technical scheme has a high degree of automation, It is also possible to recycle excess raw materials for reprocessing, which improves the utilization rate of raw materials and is more energy-saving and environmentally friendly; however, in this technical solution, there will be gaps between the recycled raw materials and raw materials, so that there are bubbles in the raw materials melted in the hot-melt tank, and the hydraulic pump The raw material with air bubbles will be transported into the hopper, so that there will be through holes in the formed product, which will affect the quality of the product formed by the molding machine, which will cause the limitation of this solution

Embodiment approach
[0033] As an embodiment of the present invention, a No. 1 magnet 74 is inlaid on the end surface of the ring 71 away from the push plate 6; a No. 2 magnet 75 is inlaid on the end surface of the turntable 24 close to the push plate 6; Magnet 75 is magnetically identical with No. 1 magnet 74; During work, ring sleeve 71 is moved close to rotating disk 24 under the drive of push plate 6, and No. 1 magnet 74 on ring sleeve 71 and No. 2 magnet 75 on rotating disk 24 mutually repel , so that the ring sleeve 71 overcomes the elastic force of the second spring 72 under the action of magnetic force and rotates around the fixing member 7. After the push plate 6 drives the ring sleeve 71 away from the second magnet 75, the ring sleeve 71 is under the action of the second spring 72. The lower relative push plate 6 returns to the original position, thereby preventing the situation that the force produced by the raw material on the ring sleeve 71 is less than the elastic force of the second ...
