Description

Technical Field

They are made through a needle-punching process and can be made into different thicknesses, feels, hardness, etc. The punching treatment of non-woven fabrics can meet a variety of application requirements and improve their functionality, such as air permeability and enhanced tear strength. Therefore, in the process of non-woven fabric production and processing, the non-woven fabric needs to be punched, so a punching device is needed. At present, the main punching method is to use a punching roller to complete it. For example, the prior art (publication number: CN219768496U) proposes a matrix hole punching device for non-woven fabrics. By adjusting the position of two sets of limit blocks on the limit rod, the limit blocks limit the position of the non-woven fabric transmission, thereby preventing the non-woven fabric from being offset during the transmission process, so that the punching roller performs stable and uniform punching processing on the non-woven fabric, thereby improving the quality of the non-woven fabric punching processing.

In the device, a winding roller and an unwinding roller are also provided at both ends of the frame 1 for winding and unwinding the non-woven fabric. This is a prior art and will not be elaborated on here. After the non-woven fabric is punched by the second punching roller group 2030, other non-woven fabrics are punched and the size of the holes needs to be changed. First, the latch 304 is removed from the inside of the mounting hole 303, that is, the latch 304 releases the limiting effect on the handle 206. The staff holds the handle 206 and rotates the handle 206 counterclockwise by 180° so that the handle 206 is clamped in the slot 302 on the other limit block 301, and then the latch 304 is inserted into the inside of the mounting hole 303 to fix the handle 206 again. At this time, the position of the second punching roller group 2030 and the position of the first punching roller group 2020 are swapped, and then the punching operation of the non-woven fabric is performed.

[0039] When punching the non-woven fabric, turn on the switch of the fan inside the box 6, and adjust the air volume by controlling the speed of the fan. This is the prior art and will not be elaborated on here. The fan blows air into the inside of the duct 7 and blows it out from the air outlet hood 8. During the punching process, the scraps of cloth that fall from the guide plate 4 can be blown into the collection box 5 for collection, which greatly reduces the workload of the staff for subsequent cleaning and reduces the labor intensity of the staff.
