The low-temperature material recovery apparatus 6 will be described in detail below with reference to fig. 6, 7, 8, 9, and 10.

The low-temperature material recovery device 6 sequentially comprises a material receiving opening 6-1, a blanking cylinder 6-2 and a material storage barrel 6-8 from top to bottom, wherein the buffering and noise reduction mechanism is arranged in the blanking cylinder 6-2. The receiving opening 6-1 is horn-shaped and used for guiding in a bar stock.

The buffering and noise reducing mechanism comprises a material carrying barrel 6-3 arranged in the blanking barrel 6-2 and guide pulleys 6-5 arranged on two sides of the top end of the blanking barrel, two sides of the top of the material carrying barrel 6-3 are suspended in the blanking barrel 6-2 through suspension ropes 6-6, the suspension ropes 6-6 are connected with counterweight bodies 6-7 by bypassing the guide pulleys 6-5, and the counterweight bodies 6-7 are arranged in counterweight protective tubes 6-4 on the outer side of the blanking barrel 6-2.

The outer diameter of the material carrying barrel 6-3 is equal to the inner diameter of the material dropping barrel 6-2 and slightly smaller than the inner diameter of the material dropping barrel 6-2, so that strong friction is avoided, and meanwhile, the blanking baffle 6-3-2 can be restrained. Or a limiting mechanism (a slide block or a roller) is arranged at the inflection point of the blanking baffle 6-3-2 to play a role in preventing friction and restraining the blanking baffle 6-3-2.

When a material rod 100 enters the blanking barrel 6-2 through the receiving port 6-1, the material carrying barrel 6-3 is positioned at the top of the blanking barrel 6-2 under the tension of the counterweight body, the blanking baffle 6-3-2 at the bottom of the material carrying barrel 6-3 is restrained by the blanking barrel 6-2 to withdraw the bottom of the material carrying barrel so that the bottom of the material carrying barrel is not closed, the material rod enters the material carrying barrel 6-3, the material carrying barrel 6-3 descends due to the gravity action of the material rod, the counterweight body ascends along with the descending of the material carrying barrel, and when the blanking baffle 6-3-2 at the bottom of the material carrying barrel is separated from the limitation of the material carrying barrel 6-2, the blanking baffle 6-3-2 is extruded under the gravity action of the material rod to swing outwards and then is opened, and the material rod falls from the material carrying barrel.
