Description

Technical Field

[0001] The utility model relates to the field of production equipment for felt rollers, and more specifically, to a forming device for felt rollers. Background Art

[0002] During the production process of felt rollers, a sleeve head made of fibers for making the roller is first sleeved on a mandrel. The rotation of rubbing rollers arranged on both sides of the mandrel drives the sleeve head to rotate synchronously. While the sleeve head is rotating, a fiber web is placed, and through the up-and-down movement of a needle punching group arranged above the sleeve head, the sleeve head is needle punched to form a roller. For the existing forming device for felt rollers, such as a felt roller device with the publication number CN 211620986U, it can complete the cutting work at one time, ensuring the cutting efficiency. At the same time, the translation mechanism can ensure that the cutting structure moves along a straight line, ensuring the neatness of the cut at the incision.
