Technical Field

[0001] The utility model relates to the technical field of fabric cutting, in particular to a cutting device for vehicle interior fabrics. Background Art

[0002] Automobile interior fabrics refer to the materials used in parts such as car seats, door trim panels, and instrument panels. They not only play a role in aesthetics but also have good touch and comfort. At the same time, they also have certain functions such as waterproof, wear-resistant, and anti-pollution. During the processing of automobile interior fabrics, a cutting device is required to cut according to the usage requirements.

[0003] At present, there are some wrinkles in the vehicle interior fabrics before cutting and they cannot be unfolded, which affects the flatness of the cutting edge and reduces the cutting accuracy. Therefore, we propose a cutting device for vehicle interior fabrics. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cutting device for vehicle interior fabrics, which has the advantages of unfolding the fabric wrinkles before cutting the vehicle interior fabrics, improving the flatness of the cutting edge, and also improving the cutting accuracy, and solves the problem that there are some wrinkles in the current vehicle interior fabrics before cutting and they cannot be unfolded, which affects the flatness of the cutting edge and reduces the cutting accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cutting device for vehicle interior fabrics includes a bottom plate. A fixed plate, a tool rest, and a conveying frame are fixedly installed on the upper surface of the bottom plate, and the tool rest is located between the fixed plate and the conveying frame. A driving roller and a driven roller are respectively rotatably installed at positions close to the upper surface and the lower surface inside the conveying frame. Spiral protrusions are symmetrically distributed at positions close to both ends on the outer surfaces of the driving roller and the driven roller. A chute is arranged on the upper surface of the fixed plate. A moving cylinder is fixedly installed outside the fixed plate. The end of the output shaft of the moving cylinder is fixedly connected with an adsorption plate, and the adsorption plate is located inside the chute. A lifting cylinder is fixedly installed on the upper surface of the tool rest, and the end of the output shaft of the lifting cylinder is fixedly connected with a cutting knife.

[0006] Preferably, one end of each of the driving roller and the driven roller close to the rear surface of the conveying frame is fixedly connected with a transmission gear, and the two transmission gears are meshed with each other.

[0007] Preferably, a conveying motor is fixedly installed on the front surface of the conveying frame, and the end of the output shaft of the conveying motor is fixedly connected with one end of the driving roller close to the front surface of the conveying frame.

[0008] Preferably, sliding rods are symmetrically fixedly connected to positions close to the front surface and the rear surface on the upper surface of the cutting knife, and the two sliding rods penetrate through the tool rest.

[0009] Preferably, a tool rest is fixedly installed inside the tool holder at a position below the cutting knife.

[0010] Preferably, suction holes are provided on the upper surface of the suction plate. An air extraction pump is fixedly installed inside the fixing plate, and the end of the input pipe of the air extraction pump is fixedly connected to the lower surface of the suction plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing a conveying frame, a driving roller, a driven roller, spiral protrusions, a tool holder, a lifting cylinder, a cutting knife, a fixing plate, a sliding groove, a suction plate and a moving cylinder, the present utility model achieves the effect of unfolding the fabric wrinkles before cutting the automotive interior fabric, improving the flatness at the cutting edge and also improving the cutting accuracy. The automotive interior fabric passes between the driving roller and the driven roller. The driving roller and the driven roller rotate synchronously and in opposite directions, so that the fabric is conveyed. At the same time, due to the existence of the spiral protrusions, the fabric is pulled in opposite directions in the horizontal longitudinal direction before and after, and before cutting, the suction plate adsorbs the fabric, and the moving cylinder drives the suction plate to move away from the tool holder, so that the fabric is pulled in opposite directions in the horizontal transverse direction, thereby unfolding the wrinkles on the fabric and maintaining a certain tension. When the lifting cylinder drives the cutting knife to complete the cutting of the fabric, the flatness at the cutting edge of the fabric is improved, and the cutting accuracy is also improved.

[0013] 2. By providing a sliding rod, the present utility model achieves the effect of improving the stability of the cutting knife, thereby improving the cutting accuracy of the automotive interior fabric. When the lifting cylinder drives the cutting knife to lift and lower, the sliding rod also rises and falls accordingly, and plays a role in limiting the lifting direction of the cutting knife, preventing the cutting knife from shifting, thereby improving the stability of the cutting knife and also improving the cutting accuracy.

Detailed Embodiments

[0018] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] As Figures 1 - 3 shown, a cutting device for vehicle interior fabric proposed by the present utility model includes a bottom plate 15. On the upper surface of the bottom plate 15, a fixed plate 1, a tool rest 6 and a conveying frame 9 are fixedly installed. The tool rest 6 is located between the fixed plate 1 and the conveying frame 9. The tool rest 6 and the conveying frame 9 are in an "n" shape when viewed from the side. Inside the conveying frame 9, a driving roller 13 and a driven roller 12 are respectively rotatably installed near the upper surface and the lower surface positions. At one end of the driving roller 13 and the driven roller 12 close to the rear surface of the conveying frame 9, transmission gears 10 are fixedly connected. And the two transmission gears 10 are meshed with each other. On the front surface of the conveying frame 9, a conveying motor 14 is fixedly installed. The end of the output shaft of the conveying motor 14 is fixedly connected to one end of the driving roller 13 close to the front surface of the conveying frame 9. The conveying motor 14 drives the driving roller 13 to rotate. The driving roller 13 and the driven roller 12 are driven by the meshed transmission gears 10. Then the driving roller 13 and the driven roller 12 rotate synchronously and in opposite directions. The vehicle interior fabric passes through between the driving roller 13 and the driven roller 12 and is conveyed.

[0020] Spiral protrusions 11 are symmetrically arranged near both ends of the outer surfaces of the driving roller 13 and the driven roller 12. And the spiral directions of the spiral protrusions 11 at both ends of the driving roller 13 and the driven roller 12 are opposite. And the spiral directions of the spiral protrusions 11 corresponding to the upper and lower parts of the driving roller 13 and the driven roller 12 are also opposite. On the upper surface of the fixed plate 1, a sliding groove 2 is provided. Outside the fixed plate 1, a moving cylinder 5 is fixedly installed. The end of the output shaft of the moving cylinder 5 is fixedly connected to an adsorption plate 3. And the adsorption plate 3 is located inside the sliding groove 2. The adsorption plate 3 is hollow inside. On the upper surface of the adsorption plate 3, adsorption holes 4 are provided. Inside the fixed plate 1, an air extraction pump 17 is fixedly installed. And the end of the input pipe of the air extraction pump 17 is fixedly connected to the lower surface of the adsorption plate 3. When the air extraction pump 17 works to extract the air inside the adsorption plate 3, the vehicle interior fabric on the adsorption plate 3 can be adsorbed.

[0021] On the upper surface of the tool rest 6, a lifting cylinder 7 is fixedly installed. The end of the output shaft of the lifting cylinder 7 is fixedly connected to a cutting knife 18. And the cutting knife 18 is located inside the tool rest 6. On the upper surface of the cutting knife 18, near the front surface and the rear surface positions, sliding rods 8 are symmetrically fixedly connected. And the two sliding rods 8 both penetrate through the tool rest 6. When the lifting cylinder 7 drives the cutting knife 18 to lift and lower, the sliding rods 8 also lift and lower accordingly. And play a role in limiting the lifting direction of the cutting knife 18, preventing the cutting knife 18 from deviating. Thus, the stability of the cutting knife 18 is improved, and the cutting accuracy is also improved. Inside the tool rest 6, at the position below the cutting knife 18, a knife seat 16 is fixedly installed. The cut vehicle interior fabric is located on the knife seat 16. The fabric cutting is completed by the cutting knife 18.

[0022] When the utility model is in use, the vehicle interior fabric passes between the driving roller 13 and the driven roller 12. The driving roller 13 and the driven roller 12 rotate synchronously and in opposite directions, so that the fabric is conveyed. At the same time, due to the existence of the spiral protrusions 11, the fabric is pulled in opposite directions in the horizontal longitudinal direction before and after. And before cutting, the adsorption plate 3 adsorbs the fabric, and the moving cylinder 5 drives the adsorption plate 3 to move away from the tool rest 6, so that the fabric is pulled in opposite directions in the horizontal transverse direction left and right, thereby unfolding the wrinkles on the fabric and maintaining a certain tension. When the lifting cylinder 7 drives the cutting knife 18 to complete the cutting of the fabric, the flatness of the cut of the fabric is improved, and the cutting accuracy is also improved.

[0023] The above specific embodiments are only several preferred embodiments of the present utility model.
