[0002] Textiles are high-consumption products used directly by individuals and families. They must undergo safety certification and meet relevant quality standards before being marketed. Certification testing for various textile fabrics must be conducted in accordance with standards, using both equipment and manpower. Before testing, the fabric must be evenly crushed to ensure more accurate test data.

[0003] Currently, pre-test preparation relies on manual labor, requiring manual cutting and preparation of test samples. This results in uneven test samples, affecting the final test data and making the test results unstable. Furthermore, due to the huge market for textiles, the testing workload is very heavy, resulting in long working hours and low efficiency. Summary of the Invention

The two sides of the pressing plate 2 are connected to the movable frame 3, and the fixed plate 4 is fixed above the movable frame 3. The feeding mechanism 5 is arranged below the workbench 1 and connected to the movable frame for moving the movable frame 3 back and forth along both sides of the workbench 1; the lifting mechanism 6 is arranged on the fixed plate 4 and connected to the pressing plate 2 for moving the pressing plate 2 up and down; the cloth cutting mechanism 7 is arranged on the fixed plate 4 for cutting the textiles on the workbench 1; the friction coefficient of the lower surface of the pressing plate 2 is greater than the friction coefficient of the upper surface of the workbench 1.

[0038] The workbench 1 is made of a resin plate with a relatively smooth panel, and the pressing plate 2 is made of a rubber plate with a relatively high friction coefficient, ensuring that the pressing plate can synchronously drive the cloth to move together when pressing the cloth downward and moving forward.

[0039] The feeding mechanism 5 is preferably driven by an electric cylinder or electric screw, which drives the movable frame 3 to move forward and backward along the two sides of the workbench 1 according to the set travel range, thereby driving the pressing plate 2 to move forward and backward on the workbench 1. Taking into account both accuracy and cost, an electric screw structure is further preferred. For example, the feeding mechanism 5 includes a first electric screw 501, a first connecting member 502, a first slider 503, a first guide rail 504 and a first bearing 505. The first electric screw 501, the first guide rail 504 and the first bearing 505 are arranged below the workbench 1. The first bearing 505 is used to support the screw of the first electric screw 501. The first guide rail 504 is arranged on both sides of the workbench 1. The first slider 503 is connected to the first guide rail 504. The first connecting member 502 is arranged horizontally below the workbench 1. Its two ends are fixedly connected to the first slider 503 respectively, and its middle part is fixedly connected to the steering gear of the first electric screw 501. The movable frames 3 are respectively fixed on the first sliders 503 and move forward and backward along the first guide rails 504 .

[0040] The lifting mechanism 6 preferably adopts an electric cylinder or an electric screw to drive the pressing plate 2 to move up and down according to the set stroke range, leaving the workbench 1 or pressing the textile sample on the workbench 1. Taking into account the accuracy and cost, the electric screw structure is further preferred. For example, the lifting mechanism 6 includes a second electric screw 601, a second connecting member 602, a second slider 603, a second guide rail 604 and a second bearing 605. The second electric screw 601 is fixed on the fixed plate 4, and the second bearing 605 is fixed on the pressing plate 2 and connected to the steering gear of the second electric screw 601; the second guide rail 604 is respectively provided on the movable frame 3 on both sides of the workbench 1, and the second slider 603 is connected to the second guide rail 604. The two sides of the pressing plate 2 are connected to the second slider 603 through the second connecting member 602, and move up and down along the second guide rail 604.

[0041] The cloth cutting mechanism 7 is one of the preferred technical solutions: it includes a hob 701, a hob shaft 702, a bearing 703, a third connecting member 704 and an electric cylinder 705, the electric cylinder 705 is fixed on the fixed plate 4, and its telescopic rod moves left and right above the workbench 1 during operation; the third connecting member 704 is connected to the telescopic rod of the electric cylinder 705 at its upper part, and connected to the bearing 703 at its lower part; the hob shaft 702 is arranged in the bearing 703, and the hob 701 is arranged on the hob shaft 702 and is located at the front edge of the pressing plate 2.

[0042] To ensure smoother cloth cutting by the cutter 701, a further preferred embodiment is to further provide the cloth cutting mechanism 7 with a shock absorber 707, secured to the third connecting member 704 via a fourth connecting member 706.

The shock absorber 707 can be an elastic component such as a spring or a metal pressure plate, and is positioned on the bearing 703 to apply elastic pressure to stabilize the movement of the cutter 701. A further preferred embodiment is to provide a sliding member, such as a slide rail 708 and a matching slider 709, between the shock absorber 707 and the third connecting member 704. The slide rail 708 is secured to the fourth connecting member 706, and the bearing 703 is fixedly connected to the slider 709. The cutter 701 and the slider 709 can move up and down within the confines of the slide rail 708.

[0043] In order to adapt to the testing of most textile samples and various testing standards on the market, the screw stepping accuracy of the feeding mechanism 5 is further set to above 1mm, and the accuracy of the lifting mechanism 6 is above 0.1mm, ensuring that strips of cloth above 1mm are cut.

[0044] During use, the fabric to be cut is inserted between the workbench and the press plate. The lifting mechanism is activated, causing the press plate to descend and compress the fabric. The feeding system activates, driving the press plate forward 1 mm. The friction of the press plate also pushes the fabric forward 1 mm. At this point, the cutting mechanism activates, cutting 1 mm strips of fabric. Once cutting is complete, the lifting mechanism raises the press plate, releasing the compressed fabric. The feeding mechanism retracts 1 mm. This cycle repeats for continuous cutting.

[0045] It should be noted here that although the above describes example embodiments of the present invention, these descriptions should not be understood in a limiting sense. Instead, several changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims.
