Problems solved by technology
[0006] 2. It is difficult to preheat large quantities of recycled plastic particles at one time, and the heating efficiency is low
[0007] 3. Use the heat generated by the heating tube to heat the falling plastic particles, so that the softening temperature of the plastic particles close to the heating tube wall is too high, and the softening temperature of the plastic particles away from the heating tube wall is too low, resulting in the softening of the plastic particle temperature uneven

Embodiment 1
[0039] see Figure 1-6 , is a schematic diagram of the overall structure of a preheating treatment system for recycled plastic particles before injection molding, including: a hopper 1, a first frame 5, and a second frame 10, and the first frame 5 and the second frame 10 are both arranged in a square shape Plate structure, the first frame 5 and the second frame 10 are oppositely fixed, that is, the first frame 5 and the second frame 10 are fixed in parallel, and a distance is provided, the first frame 5 and the second frame The opposite surface of the frame 10 is connected with a loading plate 8, the loading plate 8 is set as a square plate structure, the loading plate 8 is arranged horizontally and has four layers, and the horizontal arrangement is conducive to evenly covering the plastic particles on the top of the loading plate 8 , which is conducive to improving the softening uniformity of the plastic particles. One end of each layer of loading plate 8 is set as a movable ...

The invention discloses a pre-heat treatment system for recycled plastic particles before injection molding, and relates to the technical field of injection molding processing equipment. The system comprises a hopper, a first machine frame and a second machine frame; the first machine frame and the second machine frame are of a square-plate structure; the first machine frame and the second machineframe are oppositely fixed; the opposite surfaces of the first machine frame and the second machine frame are connected with carrying plates; and the hopper is mounted at the top end of the first machine frame and the top end of the second machine frame. The movable ends and the hinge ends of the every two adjacent carrying plates are connected to the inner walls of the first machine frame and the second machine frame in a staggered mode, a U-shaped channel allowing the plastic particles to flow is formed, an overturning plate is obliquely arranged below the carrying plates at the movable ends, thus, the plastic particles are turned over along the surface of the overturning plate when falling, and the plastic particles are prevented from softening the same side when falling to the next layer of the carrying plate for softening, so that the softening uniformity of the plastic particles is improved.
Description
technical field [0001] The invention relates to the technical field of injection molding processing equipment, in particular to a preheating treatment system for recycled plastic particles before injection molding. Background technique [0002] Recycled plastic granules are made of waste plastics processed into granules for remanufacturing. Plastic recycled granules are processed from discarded plastic products, and the market is vast; wherever there are people in the world, waste plastics will inevitably be produced, and the price is low (1200-3500 yuan / ton) and processed into recycled granules (3000-6500 yuan / ton), low cost, quick results, providing unique favorable conditions for various enterprises to open waste plastic processing plants on the spot, turning waste into treasure, sufficient raw materials, never exhausted. [0003] Recycled plastic particles need to be preheated in advance before injection molding to soften the surface and interior of recycled plastic p...
