Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a fixing device for the production and cutting of wear-resistant polyester fabrics. Background Technique

[0002] Polyester fabrics are famous for their wrinkle resistance and shape retention, and are suitable for making clothes such as coats. Polyester fabrics have relatively high strength and elastic recovery ability, are firm and durable, wrinkle-resistant and non-ironing. In addition, polyester fabrics have good light resistance and good resistance to various chemicals, are not afraid of mildew and moth damage. Wear-resistant polyester fabric is a kind of polyester fiber, which has some special properties, such as improving its wear resistance by adding some specific compounds or copolymerization.

[0003] When processing wear-resistant polyester fabrics, it is necessary to cut their sizes. However, when cutting fabrics, it is generally necessary to first clamp and fix the fabrics through a fixing device, and then perform subsequent cutting to avoid the position of the fabrics shifting during the cutting process and affecting the cutting effect of the fabrics. However, when the existing fixing device fixes the fabrics, its position is usually relatively fixed and cannot adjust the position of the fixing structure according to the fixing needs, which is inconvenient to use. Therefore, this application provides a fixing device for the production and cutting of wear-resistant polyester fabrics to meet the use requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for the production and cutting of wear-resistant polyester fabrics for the deficiencies of the prior art.

[0015] The beneficial effects of the present invention are:

[0016] (1) The utility model sets a fixing component. When the cutting knife seat moves downward, the side wall of the lower pressure plate contacts the surface of the fabric. Then, under the action of extrusion, the elastic arc plate is deformed at the first weakened groove, pushing the lower pressure plate to slide outward, so that the bottom of the lower pressure plate is fully in contact with the surface of the fabric. In the process of the lower pressure plate sliding outward, the fabric is stretched outward under the action of the protrusion at the bottom of the lower pressure plate, so that the fabric maintains appropriate tension. Since the angle between the guide groove and the cutting knife is inclined, when the cutting knife moves to cut, the fabric can be pushed outward under the action of the guide groove, stretched outward, and maintained in appropriate tension. Such a setting can, on the one hand, press down and fix the fabric, and avoid the position of the fabric from shifting during the cutting process. On the other hand, during the sliding process of the lower pressure plate, the fabric can be stretched to both sides under the action of the protrusion and the guide groove, and can be pushed outward during movement, so that the fabric maintains appropriate tension, so as to avoid uneven cutting edges caused by uneven tension.

[0017] (2) The utility model sets a rubber arc plate at the bottom of the pushing guide plate. When the lower pressing plate is pressed down, the rubber arc plate contacts the surface of the fabric. Then, when the lower pressing plate slides outward, the fabric is stretched under the push of the rubber arc plate, so that the fabric maintains appropriate tension, which can avoid uneven cutting edges caused by uneven tension.

[0018] In summary, the utility model has the advantages of simple structure and easy manufacturing. It not only satisfies the downward fixation of the fabric but also satisfies the stretching of the fabric, keeping the fabric under appropriate tension and avoiding uneven cutting edges caused by uneven tension.

In the description of the present utility model, "plurality" means two or more, unless otherwise specifically defined.

[0028] Such as Figures 1 to 6As shown in the figure, this embodiment provides a fixing device for the production and cutting of wear-resistant polyester fabrics, including a cutting machine main body 1, a fixing frame 3, and fixing components 4. A cutting tool holder 2 is arranged inside the cutting machine main body 1. The fixing frame 3 is fixedly sleeved outside the cutting tool holder 2. Two fixing components 4 are arranged on both sides of the fixing frame 3. The two fixing components 4 are in a mirror image structure. The fixing component 4 includes an elastic arc plate 401. One end of the elastic arc plate 401 is fixedly arranged on the outer wall of the fixing frame 3. The other end of the elastic arc plate 401 is provided with a lower pressing plate 403. A first weakening groove 402 is arranged on the inner wall of the elastic arc plate 401. Guide arc plates 404 are arranged at both ends of the lower pressing plate 403. A convex block 405 is arranged at the bottom of the guide arc plate 404. A guide groove 406 is arranged inside the guide arc plate 404. The guide arc plate 404, the pushing guide plate 407, and the lower pressing plate 403 are of an integral structure. The elastic arc plate 401 is in an arc structure and is made of plastic. By arranging the fixing component 4, when the cutting tool holder 2 moves downward, the side wall of the lower pressing plate 403 contacts the fabric surface. Then, under the action of extrusion, the elastic arc plate 401 deforms at the first weakening groove 402, pushing the lower pressing plate 403 to slide outward, so that the bottom of the lower pressing plate 403 fully contacts the fabric surface. And during the process of the lower pressing plate 403 sliding outward, under the action of the convex block 405 at the bottom of the lower pressing plate 403, the fabric is stretched outward, keeping the fabric under appropriate tension. Since the included angle between the guide groove 406 and the cutting tool is inclined, when the cutting tool moves for cutting, under the action of the guide groove 406, the fabric can be pushed outward, stretching the fabric outward, keeping the fabric under appropriate tension. Such a setting can, on the one hand, press and fix the fabric, avoiding the displacement of the fabric position during the cutting process. On the other hand, during the sliding process of the lower pressing plate 403, under the action of the convex block 405 and the guide groove 406, the fabric is stretched to both sides and can be pushed outward during movement, keeping the fabric under appropriate tension, and avoiding uneven cutting edges caused by uneven tension.

[0029] As an implementation manner in this embodiment, as Figure 2 and Figure 3 shown, a pushing guide plate 407 is arranged on the side wall of the lower pressing plate 403. A plurality of rubber arc plates 5 are arranged at the bottom of the pushing guide plate 407. By arranging the rubber arc plates 5 at the bottom of the pushing guide plate 407, when the lower pressing plate 403 presses down, the rubber arc plates 5 can contact the fabric surface. Then, when the lower pressing plate 403 slides outward, under the push of the rubber arc plates 5, the fabric is stretched, keeping the fabric under appropriate tension, and avoiding uneven cutting edges caused by uneven tension.

[0030] As an implementation manner in this embodiment, as Figure 2 、 Figures 4 to 6As shown, a plurality of pin holes 8 are provided inside the cutting knife seat 2, a plurality of grooves 6 are provided inside the fixed frame 3, a fixed arc plate 7 is provided inside the groove 6, the fixed arc plate 7 includes a positioning card plate 703, and connecting arc plates 701 are provided at both ends of the positioning card plate 703. One end of the connecting arc plate 701 is connected to the inner wall of the groove 6, and the two connecting arc plates 701 are in a mirror structure.

[0031] As an implementation method in this embodiment, Figure 6 As shown, a second weakening groove 702 is provided inside the connecting arc plate 701, and the two second weakening grooves 702 are mirror-image structures. The connecting arc plate 701 and the positioning card plate 703 are an integrated structure. The positioning card plate 703 is a semicircular structure and is made of plastic. By setting a fixed arc plate 7, the positioning card plate 703 is connected to the inside of the groove 6 through the connecting arc plate 701. When squeezed, the connecting arc plate 701 is deformed at the second weakening groove 702, causing the positioning card plate 703 to move inward, and then under the elastic action of the connecting arc plate 701, the positioning card plate 703 is inserted into the inside of the pin hole 8, thereby facilitating the fixed sleeve of the fixed frame 3 to the outer wall of the cutting knife seat 2.

[0032] Working steps

[0033] When in use, first fix the fixed frame 3 to the outer wall of the cutting knife seat 2, and then, under the elastic action of the connecting arc plate 701, make the positioning card plate 703 card into the inside of the latch hole 8, and then fix the fixed frame 3 to the outer wall of the cutting knife seat 2. Since the angle between the lower pressure plate 403 and the fabric is inclined, then during the downward movement of the cutting knife seat 2, the side wall of the lower pressure plate 403 contacts the surface of the fabric, and then under the action of extrusion, the elastic arc plate 401 is deformed at the first weakened groove 402, pushing the lower pressure plate 403 to slide outward, so that the bottom of the lower pressure plate 403 contacts the fabric. The surfaces are in full contact, and in the process of the lower pressing plate 403 sliding outward, the fabric is stretched outward under the action of the protrusion 405 at the bottom of the lower pressing plate 403, so that the fabric maintains appropriate tension, and when the cutting knife moves, it drives the fixed frame 3 to move. At the same time, the guide groove 406 set at the bottom of the lower pressing plate 403 can stretch the fabric outward when the fixed frame 3 moves, because the angle between the guide groove 406 and the cutting knife is inclined, so under the action of the guide groove 406, the fabric maintains appropriate tension, which can avoid uneven cutting edges caused by uneven tension.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
