Description

Technical Field

[0001] This utility model relates to the field of fabric production and processing technology, specifically to a cutting device for knitted nonwoven fabric production. Background Technology

[0002] Nonwoven fabric is a type of fabric formed by bonding fibers together physically, without interlacing or braiding yarns one by one. Because it has the appearance of cloth and many excellent properties, it is widely used in many fields such as medical, hygiene, clothing lining, agriculture, and packaging. Like other fabrics, it needs to be cut and shaped according to requirements to achieve the required size. Therefore, the cutting process is one of its core processing technologies.

[0003] Most existing nonwoven fabric cutting equipment is segmented cutting, and few can continuously cut the long side of long fabrics for extended periods. In addition, most cutting equipment lacks the function of pressing the fabric around the cutting position during cutting, which easily leads to wrinkling and bending of the fabric during cutting, resulting in dimensional and quality problems in the finished fabric.

[0004] To address the aforementioned issues, we have made improvements and proposed an edge-cutting device for knitted nonwoven fabric production. Utility Model Content

The center of the cutting saw blade 11 is rotatably connected to the center inside the blade holder 10.

[0024] A motor 12 is fixedly installed on the center of the back of the blade holder 10 by bolts. The rotating shaft of the motor 12 is coaxially fixedly connected to the central shaft of the cutting saw 11. A limiting sleeve 13 is fixedly welded to the right end of the blade holder 10. The limiting rod 9 passes through the limiting sleeve 13 and is slidably connected to the limiting sleeve 13. Two support plates 14 are fixedly welded to the top of the front and back sides of the blade holder 10 respectively. The top surface of the support plate 14 is flush with the top surface of the cloth table 2.

[0025] A crossbeam frame 15 is fixedly welded to the middle of the front and back sides of the fabric table 2. A second electric guide rail 16 is fixedly installed on the top surface inside the crossbeam frame 15 by screws.

[0027] Working Principle: In this type of knitted nonwoven fabric production edge trimming equipment, the fabric is pulled out from the output roller 3, passes through two sets of tension rollers 5 to achieve fabric tension, passes through two pressure rollers 6 to make the fabric adhere to the top surface of the fabric table 2, and finally is wound into the surface of the take-up roller 4. First, the first electric guide rail 8 and the second electric guide rail 16 are controlled to move their respective electric sliders according to the required trimming size. This, in turn, drives the blade holder 10 and its cutting saw 11, as well as the electric telescopic rod 17 and its lower pressure plate 19 to move, ensuring that the stroke is the same throughout the process. The center position of the blade 20 of the lower pressure plate 19 is always aligned with the cutting saw 11. After adjusting the cutting position, the motor 12 is started to drive the cutting saw 11 to start rotating and cutting the fabric. At the same time, the electric telescopic rod 17 is controlled to extend downward and lower the upper pressure plate 18 until the lower pressure plate 19 cooperates with the support plate 14 to press the fabric. However, the pressing force should be maintained so that the fabric can still be pulled out and moved normally. Finally, the reduction motor is started to drive the collection roller 4 to continuously pull the fabric to move and cut. The cut edge fabric and finished fabric are collected on the collection roller 4.
