Description

Technical Field

[0001] This utility model relates to the field of fabric trimming technology, specifically to an electronic-grade fiberglass fabric trimming device. Background Technology

[0002] Electronic-grade fiberglass cloth is made from electronic-grade alkali-free fiberglass yarn and produced using a plain weave process. It has excellent insulation, heat resistance, mechanical strength and dimensional stability, and is a high-performance fiberglass fabric specially used as the core substrate of copper clad laminates (CCL) and printed circuit boards (PCB).

[0003] Chinese Patent No. CN221895406U discloses a garment fabric trimming device, belonging to the field of fabric cutting technology. It includes a trimming table and uprights. The uprights are fixedly connected to the upper surface of the trimming table, and a crossbeam is fixedly connected to the upper end of each upright. There are two sets of uprights, symmetrically arranged on the lower surface of the crossbeam. A transmission chamber is opened inside the crossbeam. One set of uprights has a first support fixedly connected to its surface. The beneficial effect is that when fixing fabrics of different lengths, the fabric is first laid flat on the trimming table, and the side of the fabric to be trimmed is aligned with the cutting blade. Then, according to the fabric length, a second motor is controlled by a controller to rotate the second threaded column. With the cooperation of the two sets of second threaded columns and the second threaded tube, the distance between the two sets of fixing components changes, facilitating the fixing of fabrics of different lengths.

[0004] However, the above technical solution has the following shortcomings: it can only limit and fix the fabric from one side of the cutter. On the one hand, the fabric needs to be smoothed manually before the cutter cuts the fabric. On the other hand, the fabric is prone to curling and deforming when the cutter cuts the fabric, resulting in uneven cutting. Utility Model Content

[0037] Example 5

[0038] like Figure 3-5 As shown, the present invention discloses an electronic-grade fiberglass cloth trimming device.

[0039] Example 6
