The frame 1 is also provided with a collecting motor 64, and the rotating shaft of the collecting motor 64 is connected with a collecting rod 6 key close to the material inlet end.

The implementation principle of the embodiment is as follows:

when the degradable plastic cup after the plastic suction molding falls down and falls on the material guide plate 22 under the action of gravity, the cooling air pump 24 transmits air into the inner cavity of the material guide plate 22 through the cooling pipe 23, and then when the degradable plastic cup falls on the material guide plate 22, the material guide plate 22 not only buffers the degradable plastic cup, but also blows air out through the cooling hole 221 to further cool the degradable plastic cup; the degradable plastic cups after being buffered and cooled by the material guide plate 22 fall on the first transfer strip 34.

At this in-process transportation motor 35 start, transportation motor 35 rotates and drives first commentaries on classics roller 31 and rotate, first commentaries on classics roller 31 rotates and drives first conveying strip 34 and rotate, and it rotates roller 32 and third commentaries on classics roller 33 to drive the second through first conveying strip 34, first conveying strip 34 rotates the in-process and drives the degradable plastics cup, because the bottom of cup weight of degradable plastics cup is greater than the weight of rim of a cup, and the diameter of bottom of cup is less than the diameter of rim of a cup, and the distance of two adjacent first conveying strips 34 is the same with the internal diameter of rim of a cup, consequently the degradable plastics cup can fall into in two adjacent first conveying strips 34.

Since the second roller 32 is higher than the first roller 31, the first transfer strip 34 between the first roller 31 and the second roller 32 is inclined at an angle to transport the degradable plastic cups out of the collection tank 21. When the degradable plastic cups pass through the second roller 32, the sweeping roller 4 positioned above the second roller 32 rotates to drive the second bristles 41 to rotate.

The degradable plastic cup clamped between the first transmission strips 34 is partially higher than the first transmission strips 34, and the second brush bristles 41 contact with the first transmission strips 34, so that the degradable plastic cup is released from the clamping on the first transmission strips 34 under the pushing of the second brush bristles 41 and rolls back to the collecting groove 21 along the first transmission strips 34.

The degradable plastic cups vertically inserted into the adjacent two first transfer strips 34 have only the cup mouths higher than the first transfer strips 34, but the cup walls of the degradable plastic cups are not thick, and even if the second brush hairs 41 brush the degradable plastic cups, the degradable plastic cups cannot be swept off the first transfer strips 34, and then the part of the degradable plastic cups which are not swept off is transported from the second rotating roller 32 to the third rotating roller 33 through the first transfer strips 34.

Since the second transfer strip 54 forms an included angle with the first transfer strip 34 between the second rotating roller 32 and the third rotating roller 33, the distance between the bottom of the degradable plastic cup and the second transfer strip 54 gradually decreases during the transportation of the degradable plastic cup from the second rotating roller 32 to the third rotating roller 33, and finally the bottom of the degradable plastic cup contacts with the second transfer strip 54. As the distance between the first conveyor 34 and the second conveyor 54 decreases, the second conveyor 54 holds the degradable plastic cups up, and the mouths of the degradable plastic cups are released from the tight state of the first conveyor 34.

Meanwhile, the diameter of the third rotating disc 331 is larger than that of the fourth rotating disc 51, and the angular velocities of the third rotating disc 331 and the fourth rotating disc 51 are the same, so the linear velocity of the second conveying strip 54 is smaller than that of the first conveying strip 34, that is, the cup rim velocity of the degradable plastic cup is larger than that of the cup bottom, the cup rim of the degradable plastic cup moves forward relative to the cup bottom of the degradable plastic cup, and the cup rim of the degradable plastic cup and the first conveying strip 34 are separated from the clamping state at the moment, the degradable plastic cup can topple forward, and the cup rim faces to the direction of the base plate 55. Finally, the degradable plastic cup faces horizontally to the base plate 55 and enters the base plate 55 between two adjacent baffle plates 56 under the pushing of the first conveying strip 34 and the second conveying strip 54.

Meanwhile, collect motor 64 and rotate, collect motor 64 and drive belt 63 and rotate, and drive a plurality of collection poles 6 through belt 63 and rotate, collect pole 6 and rotate then first brush hair 61 and rotate, first brush hair 61 promotes the degradable plastic cup on the base plate 55 and slides along spacing groove 58 to the direction of keeping away from third rotor 33, and cup joint in the previous degradable plastic cup, make the degradable plastic cup cover receive integrated pile, the workman only need with become the degradable plastic cup of pile take off can.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
