Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a pearl cotton horizontal and vertical slitting machine with a knife adjustment structure. Background Art

[0002] Pearl cotton is a new type of environmentally friendly packaging material with cushioning, shock absorption and shock resistance. It has a series of excellent use characteristics such as heat preservation, moisture resistance, heat insulation, sound insulation, friction resistance, aging resistance and corrosion resistance. It can be cut into specified lengths to protect the product during packaging. It can absorb and disperse external impact force by bending, and can protect the product during transportation.

[0003] It has been found in actual use that the existing pearl cotton slitting machine has the following shortcomings:

[0004] The adjustment of the slitting knife position of domestic pearl cotton slitting machines is almost always carried out in the state of parking, which has relatively high labor intensity, poor safety, and is easy to cut hands. For non-online slitting and rolling equipment, manual knife adjustment after parking is economical and practical. For online slitting and rolling equipment, different knife adjustment methods can be selected due to different production speeds and batches. When the speed is low, the batch is large, and the slitting width does not need to be changed frequently, manual knife adjustment after parking can be selected. When the speed is fast, the batch is small, and the slitting width needs to be changed frequently, manual knife adjustment after parking obviously cannot meet the requirements of online continuous production.

[0005] Therefore, the present application provides a pearl cotton horizontal and vertical slitting machine with a knife adjustment structure to meet the needs. Utility Model Content
