DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an automatic backfilling device for expanded waste, including a crushing box 1, a motor 2 is fixed to the upper end surface of the crushing box 1, a rotating shaft 3 is fixed to the output end of the motor 2, and the rotating shaft 3 is connected to the crushing box 1 by a bearing. A first guide ring plate 5 with a concave structure is also fixed in the crushing box 1, a second guide ring plate 6 is arranged on the lower side of the first guide ring plate 5, and the second guide ring plate 6 is connected to the rotating shaft 3 by a bearing. A conveying pump 8 is also connected to the crushing box 1.

[0019] A feed box 101 is installed on the upper end surface of the crusher box 1, and a dividing plate 102 with an inclined structure is arranged in the feed box 101, and the dividing plate 102 is fixed to the upper end surface of the crusher box 1; a cam 301 is also fixed on the rotating shaft 3, and a crushing knife 302 is also fixed on the rotating shaft 3 at an equal angle, and a spiral conveying rod 303 is fixed to the lower end of the rotating shaft 3; the cam 301 and the movable rod 7 are slidably connected, and the movable rod 7 is symmetrically distributed about the center line of the crusher box 1, and the movable rod 7 and the crusher box 1 are slidably connected; a baffle 701 is also fixed on the movable rod 7, and the baffle 701 cooperates with the upper opening of the crusher box 1 to achieve a shielding effect, and one end of a spring 702 is also fixed on the movable rod 7, and the other end of the spring 702 is fixed to the inner wall of the crusher box 1;

[0020] When using the automatic backfilling device for expanded waste, Figure 1-Figure 3As shown, first, the whole device is moved to cooperate with the extruder, so that the feed box 101 is located directly below the discharge port of the extruder. At this time, the return material generated by the extruder due to the extrusion and modulation of the particles falls directly into the feed box 101 and is collected. Then, the motor 2 is powered by an external power supply. By starting the motor 2, the rotating shaft 3 can be driven to rotate, thereby driving the cam 301 to rotate. Through the sliding action between the cam 301 and the movable rod 7 and the elastic action of the spring 702, the movable rod 7 can be forced to reciprocate left and right. When the movable rod 7 moves, the baffle 701 is driven to move at the same time. When the baffle 701 is separated from the upper opening of the crushed material box 1, the shielding effect of the upper opening of the crushed material box 1 can be released, so that the return material in the feed box 101 can enter the crushed material box 1. When the baffle 701 cooperates with the upper opening of the crushed material box 1 to achieve shielding, the feeding is stopped at this time, thereby effectively avoiding excessive feeding at one time to affect the crushing effect of the material.

[0022] When the material enters the crushing box 1, Figure 1-Figure 3 As shown, at this time, the material can be crushed by the action of the crushing knife 302. With the first guide ring plate 5 with a concave structure and the second guide ring plate 6 with a convex structure, the flow path of the material can be "Z"-shaped, thereby extending the material movement time, thereby ensuring the material crushing time, and then ensuring the material crushing effect, making the material muddy, and the crushed material flows downward. With the action of the scraper 401, the scraping and collecting effect of the material can be realized, so that the material can quickly contact the spiral conveying rod 303. The material can be conveyed downward by the spiral conveying rod 303. With the action of the conveying pump 8 and the feeding pipe 801, the muddy material can be backfilled into the extruder for processing, thereby avoiding material waste. This is the working principle of the automatic backfilling device for expanded waste.
