Description

Technical Field

[0001] This utility model relates to the field of fabric cutting equipment, specifically to a fabric cutting equipment with a film-coated and fixed structure. Background Technology

[0002] The apparel, bag, and textile industries commonly use flatbed cutting equipment for automated fabric cutting. During the cutting process, the fabric needs to be fixed on the cutting platform, usually using vacuum adsorption. However, this method has drawbacks: when the fabric is breathable, such as lace or mesh, the vacuum adsorption method is less effective at holding the fabric in place. The fabric placed on the cutting platform is prone to shifting during the cutting process, reducing the accuracy of the cut and affecting the final result. Therefore, the fabric fixing method needs to be improved. Utility Model Content

[0003] To address the technical problem of poor vacuum adsorption and fixation effect of breathable fabrics, this utility model discloses a fabric cutting device for film coating and fixation, including a cutting platform, a cutting mechanism, and a film coating mechanism. The film coating mechanism comprises a film roller, an upper pressure plate, a support plate, and a clamping device for holding the film. The film roller is located on one side of the cutting platform; the upper pressure plate and the support plate are located in front of the film roller, placed opposite each other to form a film conveying channel. A pressing drive device is provided on the upper pressure plate or the support plate to press the upper pressure plate and the support plate together; the clamping device is movable along the cutting platform; and recesses are provided at the front ends of both the lower pressure plate and the support plate, the size of which matches the size of the clamping device so that the clamping device can extend into the recesses.

[0004] Furthermore, the fabric cutting equipment also includes a conveyor belt and a feeding device for conveying fabric. The conveyor belt is located on the cutting platform and moves along the cutting platform. The feeding device includes a crossbar, a feeding wheel, and a feeding drive device. The crossbar is located between the conveyor belt and the support plate. The feeding wheel is installed on the crossbar. The feeding drive device is connected to the crossbar and is used to drive the crossbar to lift or lower, so that the feeding wheel lifts upward or presses downward against the conveyor belt.

[0005] Furthermore, the feeding wheel includes a base plate and a rubber wheel, and the base plate is provided with a tension spring.

[0006] Furthermore, the clamping device is mounted on a crossbeam that can move along the cutting platform. The clamping device includes an upper clamping plate, a lower clamping plate, and a clamping cylinder. The clamping cylinder drives the lower clamping plate to clamp the film.

[0007] Furthermore, the coating mechanism also includes a cutter located in front of the upper pressure plate and the support plate, for cutting the film.

[0008] Furthermore, the cutting mechanism is mounted on the crossbeam, and the cutting structure includes a cutting blade and an inkjet device.

[0009] Furthermore, the cutting platform includes multiple adsorption holes on its surface, a vacuum pipe connecting the adsorption holes, and a negative pressure source connected to the vacuum pipe. The cutting platform uses negative pressure to keep the film and the fabric fixed.

[0010] Furthermore, a vision system is provided above the cutting platform, and the vision system includes at least one camera.

[0011] The beneficial effects of this invention are as follows: This equipment has a film-coating mechanism that, while the fabric is being conveyed, covers the conveyed fabric with an airtight transparent film, thereby firmly adhering the fabric to the vacuum cutting platform and ensuring that the fabric does not move during the cutting process, thus improving cutting accuracy and cutting effect. The film-coating operation of this equipment is convenient and the process is simple. Only the clamping device needs to continuously move back and forth to pull out and cut the film. The film-coating process requires no manual operation and can be automated, proceeding synchronously with the fabric conveying, thereby improving production efficiency. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0015] Figure 1 This is a top view of the fabric cutting equipment of this utility model, including a cutting platform 1, a cutting mechanism 2, and a coating mechanism 3. The cutting platform 1 is a flat vacuum adsorption platform with multiple adsorption holes evenly distributed on its surface. These adsorption holes are connected to vacuum pipes, the other end of which is connected to a vacuum pump. Under the action of the vacuum pump, the cutting platform achieves negative pressure adsorption of the fabric. A crossbeam 4 is provided above the cutting platform. The crossbeam 4 moves along the platform via guide rails on both sides. The cutting mechanism is mounted on the crossbeam 4 and can move along it. The coating mechanism 3 includes a film roller 31, an upper pressure plate 32, a support plate 33, and a clamping device 34. The film roller 31 is used to unwind the film and is mounted on one side of the cutting platform 1. Figure 3 As shown, the upper pressure plate 32 and the support plate 33 are mounted on the front side of the film roller 31, where the front side is defined as the side facing the cutting platform. The upper pressure plate 32 and the support plate 33 are placed vertically opposite each other, forming a film conveying channel between the two plates. The film is unwound from the film roller 31 and passes through the film conveying channel between the two plates. The upper pressure plate 32 or the support plate 33 is equipped with a pressing drive device 36. For example, the upper pressure plate 32 is connected to a cylinder, which drives the upper pressure plate 32 to press down and press against the support plate 33 to press the film.

[0016] like Figure 2 As shown, the clamping device 34 is mounted on the crossbeam 4 and can move along the cutting platform 1. Figure 3 As can be seen, the clamping device 34 includes an upper clamping plate 341, a lower clamping plate 342, and a clamping cylinder 343. Recesses 37 are provided at the front ends of both the upper pressure plate 32 and the support plate 33. The size of the recesses 37 matches the size of the clamping device 34, allowing the clamping device 34 to extend into the recesses 37. The number of recesses 37 is the same as the number of clamping devices 34, and their positions correspond one-to-one. After the film enters the film conveying channel between the two plates, the clamping device 34 extends into the recesses 37, and the clamping cylinder 343 drives the upper clamping plate 341 and the lower clamping plate 342 to clamp the film. Then, the clamping device moves forward, pulling the film out so that it unfolds above the cutting platform 1. The laminating mechanism also includes a cutter 35, located in front of the upper pressure plate 32 and the support plate 33, used to cut the film.

[0017] A conveyor belt 5 covers the cutting platform 1, continuously conveying fabric forward. A feeding device 6 for conveying fabric is also provided below the support plate, such as... Figure 4As shown, the feeding device 6 includes a crossbar 61, a feeding wheel 62, and a feeding drive device 63. The crossbar is located between the conveyor belt 5 and the support plate 33. The feeding wheel 62 is mounted on the crossbar 61. The feeding drive device 63 is a cylinder connected to the crossbar 61, used to drive the crossbar 61 to lift or lower, causing the feeding wheel 62 to lift upwards or press downwards against the conveyor belt 5. The feeding wheel 62 includes a base plate 621 and a rubber wheel 622. A tension spring 623 is mounted on the base plate 621. When feeding fabric, the roller for unwinding lace or mesh is placed below the film roller 31. The feeding wheel 62 presses the fabric, causing it to move forward with the conveyor belt 5. The tension spring 623 on the feeding wheel 62 exerts downward pressure on the rubber wheel 622, ensuring that the rubber wheel 622 remains in close contact with the conveyor belt 5. While the fabric is being conveyed, the clamping device 34 pulls the film out to a predetermined position, the upper pressure plate 32 descends to press the film, the cutter 35 cuts the film, the clamping device 34 releases the film, and the film covers the fabric below, thereby firmly adhering the fabric to the cutting platform 1.

[0018] The cutting mechanism 2 includes cutting blades and an inkjet printer. After the fabric is fixed by a film coating, the cutting mechanism 2 performs cutting or coding operations on the fabric. A vision system is also installed above the cutting platform 1 for identification and monitoring.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
