Description

Technical Field

[0001] The utility model relates to the technical field of bag-making machine cutting, in particular to a bag-making machine positioning and cutting device. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. When the bag making machine is unloading the materials, cutting equipment is needed to cut the plastic packaging bags.

[0003] The cutting equipment of most bag-making machines today is too simple in structure, and cannot effectively position and fix the ends of plastic packaging bags during cutting. The plastic packaging bags cannot be tightened, resulting in cutting errors. The cut plastic packaging bags mostly fall naturally due to inertia when being removed, which can easily lead to material jamming. Utility Model Content

The second motor 9 and the third motor 10 are convenient for driving the first conveying cylinder 6 and the second conveying cylinder 7 to rotate towards each other to realize the clamping and conveying of the plastic bag. The first motor 8 is convenient for driving the positioning and stripping cylinder 5 to rotate, so as to realize the positioning block 53 to position the end of the plastic bag and strip the material.

[0026] In this embodiment, the stripping platform 4 is designed in a trapezoidal shape, a cutting opening 41 is provided at the top of the stripping platform 4, and a slope surface 42 is provided on one side of the stripping platform 4 to facilitate hanging of the plastic bags to be cut.

[0027] In this embodiment, the positioning and stripping barrel 5 is close to the bottom end of the sloped surface 42 of the stripping platform 4, and a reset groove 51 is opened at one end of the positioning and stripping barrel 5, and a reset spring 52 is fixedly connected in the reset groove 51, which is convenient for driving the positioning block 53 to reset, and the end of the reset spring 52 away from the reset groove 51 is fixedly connected to the positioning block 53, and the corner of the positioning block 53 away from the reset spring 52 is provided with a notch, which is convenient for compacting and positioning the end of the plastic bag and subsequent stripping.
