Description

Ring knife for opening bag

Technical Field

The utility model belongs to the technical field of the cutter, especially, relate to an open bag ring sword.

Background

In the production feeding process, a material bag is usually moved to the side of a feeding port of a mixing device, if the material bag is bundled by using a bundling rope, a cutter beside the feeding port needs to be taken up to cut the bundling rope of the material bag, if the material bag does not have the bundling rope, the cutter beside the feeding port needs to be taken up to seal and cut a bag body of the material bag, then the cutter is taken back to the side of the mixing device, then the material is put into the mixing device, when multiple bags of materials need to be put into, on one hand, the cutter needs to be frequently taken up and put down at the feeding port, and at this time, the risk that the cutter falls down to damage the device is generated. On the other hand, the cutter is taken up and put down, so that the time waste is caused, the working efficiency is reduced, and moreover, the cutter beside the feed opening can conveniently cut off the bag bodies of the strapping rope and the material bag, or two pairs of different cutters are prepared for respectively cutting the bag bodies of the strapping rope and the material bag, so that the production cost is not controlled and the operation is not smooth.

Chinese patent application CN 110239799 a discloses a ring that cuts off of wrapping bag bundling, as shown in fig. 1, it includes the ring, is equipped with the through-hole in the ring, is equipped with the cutting board in the outer one side of ring, is equipped with the cutting groove on the cutting board, installs the cutting knife in the cutting groove. It can be seen that although the structure does not need to be frequently picked up and put down for cutting during operation, the structure is more suitable for cutting the strapping rope, and the packaging bag body of the material bag cannot be conveniently cut.

Chinese patent CN 203843871U discloses an edible fungus bag cutting knife, as shown in FIG. 2, comprising a finger ring and a blade, wherein the finger ring is in a circular ring structure matched with fingers, and the blade is fixedly arranged at the outer side of the finger ring; the ring is arranged to be of a circular ring structure matched with the finger, the blade is arranged on the outer side of the ring, the ring can be worn on the finger of an operator like a ring during use, the opening can be cut while picking mushrooms, the bag cutting work can be completed by only one hand, and the finger ring is simple and convenient to use, easy to carry and not easy to lose. It can be seen that this structure still can be taken up and put down to cut without frequent, but is applicable to the cutting to the bag body more, and inconvenient cutting of carrying out the strapping, especially when the strapping intensity is higher, thicker or quantity is more, this structure is unfavorable for the cutting more.
