| 摘要 |
The present invention discloses a rubber band machine. The length of a rubber band to be conveyed may be set by controlling the angle of rotation of a first motor. The rubber band input by a first feeding drive wheel is stored between the first feeding drive wheel and a second feeding drive wheel so that the second feeding drive wheel coordinates with a looping device to continue to output the rubber band. During feeding, the rubber band machine can perform joint examination and ironing to the rubber band, and automatically cut the rubber band off at the discharge port of the second feeding drive wheel via a cutting device. The looping device grips the rubber band via a third gripper and moves rotationally to convey two ends of the rubber band to a first gripper and a second gripper, respectively. After the first gripper and the second gripper have gripped the two ends of the rubber band, the rubber band forms a rubber ring by rotational motion of the first gripper and the second gripper, and the two jointed ends of the rubber ring are fixed on a bracket for subsequent sewing and fixation. The looping device has the advantages of simple structure and automatic control, and the looping speed of rubber bands is thus greatly improved. |

1. A rubber band machine, comprising a feeding device, a cutting device and a looping device, characterized in that the feeding device comprises a first rack (1) and a second rack (2) arranged at an interval, the first rack (1) being provided with a first feeding drive wheel (3) driven by a first motor (31), the second rack (2) being provided with a second feeding drive wheel (4) driven by a second motor (41); the looping device comprises a first gripper (62) capable of rotating around a first axis, a second gripper (63) capable of rotating around a second axis, a bracket (61) disposed between the first gripper (62) and the second gripper (63), and a third gripper (57) capable of rotating around a third axis; wherein the first feeding drive wheel (3) rotates and inputs a predetermined length of rubber band between the first feeding drive wheel (3) and the second feeding drive wheel (4), the third gripper (57) grips one end of the rubber band at a discharge port of the second feeding drive wheel (4) and rotates around the third axis under auxiliary feeding of the second feeding drive wheel (4) to allow a predetermined length of the rubber band to pass through the first gripper (62) and the second gripper (63), and then the rubber band at the discharge port of the second feeding drive wheel (4) is cut by the cutting device; and wherein after each gripping a respective one of two ends of the cut rubber band, the first gripper (62) and the second gripper (63) rotate around the first axis and the second axis, respectively, to fix the two ends of the rubber band onto the bracket (61). |
