Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric cutting mechanism. Background Technology

[0002] Velvet fabric is a relatively precious material. Due to its high cost, it is generally used in more expensive clothing. In order to make full use of the fabric, it is usually cut by hand. However, the hand method is inefficient and has poor precision. In order to ensure sufficient room for modification after cutting, a large allowance is usually left, which inevitably leads to unnecessary waste of materials.

[0003] Chinese utility model patent application number 202222300449.2 discloses a cutting mechanism for velvet fabric. The above technical solution can drive the fabric to be unwound and conveyed by the set feeding roller and the recovery roller. After being conveyed to the corresponding position, it is cut. However, during the conveying, it can only ensure that the fabric is kept taut and flat in the longitudinal direction. In the transverse direction, the fabric will deform when it is rolled up, and wrinkles will easily appear. Therefore, if the cut part is not flat enough, it will affect the cutting accuracy of the fabric.

[0004] Therefore, a fabric cutting mechanism is proposed. Utility Model Content

The fabric conveying support plate is provided with a flattening component for laterally flattening the velvet fabric. The flattening component includes a slide rail, a motor, a bidirectional lead screw, a slider, a second electric telescopic rod, a fixed plate, a flattening roller, and a second connecting plate.

[0008] Furthermore, the support frame is arranged on both sides of the fabric conveying support plate, and the velvet fabric take-up roller and the velvet fabric unwind roller are respectively rotatably arranged on one of the support frames to realize synchronous unwinding and conveying of the velvet fabric.

[0024] like Figure 1-4As shown, a fabric cutting mechanism includes a fabric conveying support plate 1, a support frame 2, a velvet fabric take-up roller 3, a velvet fabric unwind roller 4, a cutting mold 5, and a cutting component 6. The fabric conveying support plate 1 is provided with a flattening component 7 for laterally flattening the velvet fabric. The flattening component 7 includes a slide rail 701, a motor 702, a bidirectional lead screw 703, a slider 704, a second electric telescopic rod 705, a fixing plate 706, a flattening roller 707, and a second connecting plate 708. Specifically, the velvet fabric take-up roller and the velvet fabric unwind roller 4 are used for unwinding and conveying the velvet fabric, thus ensuring that the fabric remains longitudinally flattened during conveying. The flattening component 7 can laterally flatten the fabric corresponding to the cutting mold 5, ensuring that it remains taut during cutting, thus resulting in more accurate fabric dimensions.

[0025] like Figure 1-2 As shown, the support frame 2 is set on both sides of the fabric conveying support plate 1. The velvet fabric take-up roller 3 and the velvet fabric unwind roller 4 are respectively rotatably set on one of the support frames 2 to realize the synchronous unwinding and conveying of the velvet fabric. Specifically, the velvet fabric take-up roller 3 and the velvet fabric unwind roller 4 are respectively driven by motors of the same power and model to achieve synchronous rotation and realize the unwinding and conveying of the velvet fabric. The conveying structure is existing technology, so it will not be described in detail here.

[0026] like Figure 4 As shown, the top of the cutting mold 5 has multiple mold slots 501. The cutting component 6 includes a mounting frame 601, a first electric telescopic rod 602, a first connecting plate 603, and a mold blade 604, which realizes the cutting and processing of velvet fabric. The mounting frame 601 is set at the top of the fabric conveying support plate 1. The first electric telescopic rod 602 is set at the bottom of the inner part of the mounting frame 601. The first connecting plate 603 is connected to the telescopic end of the first electric telescopic rod 602. The mold blade 604 is connected to the first connecting plate 603. Specifically, the mold blade 604 and the mold slots 501 are adapted to each other, so that the velvet fabric can be cut with equal mold pressure.

[0027] like Figure 3 As shown, there are two slide rails 701, which are distributed on both sides of the bottom of the cutting mold 5. Two sliders 704 are slidably arranged inside the two slide rails 701 respectively. The two sliders 704 on the two slide rails 701 are in opposite positions and are connected by the second connecting plate 708.

[0028] like Figure 3As shown, a motor 702 is provided on one side of one of the slide rails 701, and a bidirectional lead screw 703 is connected to the main shaft end of the motor 702. Two sliders 704 on the same side as the bidirectional lead screw 703 are threaded onto it. Specifically, the operation of the motor 702 can drive the bidirectional lead screw 703 to rotate, thereby driving the two sliders 704 to move closer or further away from each other, and thus driving the two flattening rollers 707 to move closer or further away from each other.

[0029] like Figure 3 As shown, each slider 704 has a second electric telescopic rod 705 at its top. The fixed plate 706 is connected to the telescopic end of the second electric telescopic rod 705. The flattening roller 707 is located below the two fixed plates 706 in opposite positions on different slide rails 701. Specifically, the second electric telescopic rod 705 has the same power and model, which can drive the flattening roller 707 to move up and down smoothly. The rotating shaft of the flattening roller 707 is equipped with a corresponding damping structure, that is, it has a certain resistance when rotating, and will not rotate when there is no external force. The damping structure is existing technology, so it will not be described in detail here. Under the action of the damping structure, after the flattening roller 707 contacts the fabric, when the two flattening rollers 707 move in opposite directions, the fabric can be flattened laterally. When conveying and cutting the fabric, the height of the second electric telescopic rod 705 can be adjusted to ensure that the fabric is squeezed with a certain force. Pressure sensors and other structures can also be used, but these will not be described in detail here.

[0030] In summary: the velvet fabric take-up roller 3 and velvet fabric unwind roller 4 can drive the unwinding and conveying of the velvet fabric, ensuring the longitudinal flatness of the velvet fabric during conveying. Then, under the action of the flattening component 7, the velvet fabric can be flattened laterally. Therefore, when the fabric is cut by the cutting component 6, the fabric can be kept flat, ensuring that the fabric is flat during cutting and that the cutting accuracy is not affected by the fabric wrinkles.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
