Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, in particular to a slitting machine provided with an adaptive clamping mechanism. Background Art

[0002] In the production process of fabric, the fabric needs to be cut. In the prior art, fabric slitting machines are mostly used for cutting fabric. When the fabric slitting machines cut the fabric, the cutting speed is often not fast enough, resulting in uneven fabric cuts. In addition, there are hair scraps on the fabric cuts, and even loose edges in severe cases, which seriously affects the quality of the fabric and leads to low production yield and low production efficiency.

[0003] In order to solve the above problems, reference may be made to a cloth slitting machine disclosed in the prior art (Chinese patent application number CN201720295371.6, application date 2017-03-24), which is provided with a cloth pulling mechanism and a pressing plate device, so that the cloth slitting machine has the advantages of fast cutting and smooth cut of the cloth bag; and reference may also be made to a cloth ultrasonic slitting machine disclosed in the prior art (Chinese patent application number CN201720948354.8, application date 2017-08-01), which is provided with an air blowing mechanism to remove the ultrasonic wave generated in the strip cutting process. The waste scraps are blown away promptly and quickly to prevent the waste scraps from remaining on the fabric after slitting, which is beneficial to the collection of fabric and the processing and production of subsequent products. The invention also provides a fully automatic ultrasonic Velcro slitting machine disclosed in the prior art (application number CN201520957463.7, application date 2015-11-26 Chinese patent). The slitting machine can control the distance between the cutter head and the fabric roller through the arrangement of the positioning groove and the limiting rod, which is convenient for cutting fabrics of different thicknesses and also protects the safety of the operator when placing the fabric. The cooling chamber arranged inside the fabric roller can reduce the temperature of the fabric after cutting and protect the fabric from being damaged.

[0004] Although the above device can avoid the problem of affecting the cloth, there are still certain shortcomings in actual use. When the cloth is driven to rotate at high speed during actual operation, the cloth is very likely to shift due to the centrifugal force, which leads to excessive waste of cloth when the cloth is cut into strips and not cut to the bottom, resulting in waste in the process of cutting the cloth.
