Further, the sliding groove comprises an annular groove and a linear groove which are arranged along the length direction of the rotary telescopic shaft, the annular groove is respectively arranged at two ends of the linear groove, and the rotary telescopic shaft extends and retracts in the linear groove and rotates in the annular groove. The arrangement of the linear groove is to ensure that the rotary telescopic shaft can only vertically move up and down when the rotary telescopic shaft extrudes the recycled plastic, so that the equipment damage caused by deviation from the axis and the extrusion molding effect are avoided. The design of the annular groove is to enable the rotary telescopic shaft to rotate, so that the heating pipeline can be stirred, and the texture of the heating pipeline is uniform; the scraper can rotate to scrape the recycled plastic falling on the back of the compression disc, and accumulation is avoided.
Furthermore, a sliding block is fixedly installed on the shaft body of the rotary telescopic shaft, and the outer contour of the sliding block is matched with the groove sections of the annular groove and the linear groove. The purpose of the slider is to define the direction of movement of the rotary telescopic shaft, and to enable the slider to move up and down in a linear groove and rotate in an annular groove.
Furthermore, a vortex-shaped sliding groove is formed in the shaft body of the rotary telescopic shaft and is arranged above the sliding block; an annular driving piece is slidably mounted on the outer side of the rotary telescopic shaft, the driving piece and the rotary telescopic shaft are coaxially arranged, a driving block is arranged on the inner wall of the driving piece, and the outer contour of the driving block is matched with the groove section of the vortex-shaped sliding groove.

In order to avoid that the heating pipeline cannot be heated in time to melt due to the fact that excessive recycled plastics are fed at one time, the blocking plate positioned at the upper end of the driving piece plays a role in batch feeding. Retrieve plastics and pile up in throwing the material district, when the driving piece was downward, the baffler moved down and gets into melting portion, because the setting of work furnace horn mouth, the partial recovery plastics that throw the material district get into melting portion, when the driving piece upwards, the baffler closed horn mouth, and the messenger throws the unable melting portion that gets into of recovery plastics in material district, makes things convenient for the heating pipeline in time to heat.

when the rotary telescopic shaft 4 rotates, the heating pipeline 61 in the melting part 11 of the working furnace 1 rotates along with the rotary telescopic shaft to stir the plastic, and the recovered plastic is heated and stirred to be in a molten state because the heating pipeline 61 generates heat (an electric heating pipe);
when the rotary telescopic shaft 4 rotates, the scraper 44 fixedly installed on the rotary telescopic shaft 4 also rotates to scrape off the recycled plastic which enters the extrusion part 12 from the melting part 11 of the working furnace 1 through the filter plate 2 and falls on the back of the compression disc 43, thereby avoiding accumulation.
After extrusion is completed, the force of the driving piece 5 is upwards contracted, the driving block 51 upwards drives the rotary telescopic shaft 4, the rotary telescopic shaft 4 upwards moves, the sliding block 42 in the rotary telescopic shaft 4 enters the linear groove 32 from the annular groove 31 at the lower end, and the linear groove 32 moves to ensure that the rotary telescopic shaft 4 vertically upwards moves; when the telescopic shaft 4 is rotated upwards, the slide block 42 enters the annular groove 31 at the upper end in the sliding groove 3 from the linear groove 32, and at the same time, the driving block 51 in the driving member 5 is still forced upwards, so that the driving block 51 slides from the lower section to the upper section of the spiral chute 41 in the telescopic shaft 4, the telescopic shaft 4 starts to rotate, the slide block 42 also slides in the annular groove 31 at the upper end in the sliding groove 3, and simultaneously the heating pipeline 61 and the scraper 44 rotate along with the rotation, thereby completing a work flow.
In order to avoid that the heating pipeline cannot be heated in time to melt due to the fact that excessive recycled plastics are fed at one time, the blocking plate positioned at the upper end of the driving piece plays a role in batch feeding. Retrieve plastics and pile up in throwing the material district, when the driving piece was downward, the baffler moved down and gets into melting portion, because the setting of work furnace horn mouth, the partial recovery plastics that throw the material district get into melting portion, when the driving piece upwards, the baffler closed horn mouth, and the messenger throws the unable melting portion that gets into of recovery plastics in material district, makes things convenient for the heating pipeline in time to heat.

s1: firstly, sorting recycled plastics, particularly placing electroplating and paint spraying materials separately;
s2: carrying out chemical treatment, deplating and paint removing on the recycled plastic;
