Therefore, automatic cutting machines have become a major innovation in cutting technology in the clothing industry and have gradually become popular in various companies. At present, the cloth cutting mechanism of the automatic cutting machine includes a track and a knife block. The blade cuts along the track. When the cloth is pulled, the track serves as a support for cutting and a clamp for fixing the cloth. When repeated cutting is performed, the track needs to be lifted after each cutting and pressed on the cut cloth, which not only provides support for the next cutting, but also fixes the newly cut cloth.

[0003] However, if the track is designed to be too wide or is lifted too quickly, the fabric may curl. Utility Model Content

The basic principles of the utility model defined in the following description can be used for other implementation schemes, variations, improvements, equivalent schemes, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0029] Those skilled in the art should understand that, in the disclosure of the present invention, the directions or positions indicated by the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0031] See also Figure 1-Figure 4 The cloth clamping device of the automatic cutting machine comprises a first pressing plate 1 and a second pressing plate 2; the first pressing plate 1 and the second pressing plate 2 are connected by a connecting member 5 and can be flattened and folded; the first pressing plate 1 and the second pressing plate 2 are arranged on the cutting machine in a flattened posture for pressing the cloth.

[0032] The first pressing plate 1 and the second pressing plate 2 are connected to a combined cloth clamp, and the cloth clamp and the cutting table are used to cut and press the cloth; and the two ends of the cloth clamp are delayed and connected to the end plate 3 after the cutting table, and the end plate 3 is installed on the cylinder 4 set on the side of the cutting table, and the cylinder 4 controls the lifting and lowering of the cloth clamp.

[0033] In the embodiment of the present application, the cloth clamp is folded at the moment of being lifted, and is flat when being lifted and placed on the cutting table. The effect is achieved by the control of the cloth clamp by the winding seat 6 and the pulling structure provided on the end plate 3 in cooperation with the rope 7. The winding seat 6 is provided in the middle of the bottom surface of the end plate 3, and a rope 7 is fixed to the side of the end of the first pressing plate 1 and the second pressing plate 2, i.e., the side of the cloth clamp. The rope 7 is connected to the pulling structure after passing through the winding seat 6; the connecting member 5 is provided in the middle of the side of the winding seat 6, and the connecting member 5 is connected to the side of the end of the first pressing plate 1 and the second pressing plate 2, i.e., the middle of the cloth clamp. That is, the pulling structure will be connected to the cutting table and shield around the connecting member 5 at the moment of being lifted by the first pressing plate 1 and the second pressing plate 2, and then reset and unfold.

[0034] In the embodiment of the present application, the pulling structure is composed of an elastic member 8 and two magnetic sheets 9 capable of magnetic attraction, one of the two magnetic sheets 9 is fixed to the side of the cutting table, and the other is connected to the winding seat 6 through the elastic member 8. When the first pressing plate 1 and the second pressing plate 2 are placed on the cutting table, the two magnetic sheets 9 attract each other, and the elastic member 8 stretches naturally. When the first pressing plate 1 and the second pressing plate 2 are lifted, the two magnetic sheets 9 attract each other until the elastic member 8 is stretched and deformed, so that the rope 7 is pulled toward the winding seat 6, causing the first pressing plate 1 and the second pressing plate 2 to fold; then as the lifting height increases, the magnetic sheets 9 separate, and the elastic member 8 immediately resets.

[0035] It should be noted that the elastic member 8 can be configured to have low oscillation or no oscillation to reduce the oscillation effect thereof during resetting, so as to ensure the efficiency of the lifting and pressing.

[0036] In the embodiment of the application, the return speed of the cylinder 4 is set very fast, and the influence of the suction force of the magnetic sheet 9 approaching on the spreading of the first pressing plate 1 and the second pressing plate 2 during the return stroke can be ignored.

[0037] In some embodiments, the magnetic sheet 9 may be formed by two common workpieces with an adhesion effect, so as to avoid interference of magnetic attraction during the return process.

[0038] In an embodiment of the present application, a cutting groove 11 is formed in the middle of the first pressing plate 1 and the second pressing plate 2 when they are spread out, and a cutting knife 10 controlled by the gantry center is provided above the cutting groove 11. After the cloth is stretched flat on the cutting bed, it is cut along the cutting groove 11 by the cutting knife 10. Before the cloth is stretched again, the first pressing plate 1 and the second pressing plate 2 are lifted, and the edges of the cut cloth fall under the first pressing plate 1 and the second pressing plate 2. The folding of the first pressing plate 1 and the second pressing plate 2 during the lifting process can prevent the cloth from curling.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
