[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figure 1 shown, the present invention provides a waste edge shearing device for sheet materials, including a support assembly 1 and a cutting assembly 2. The support assembly 1 is used to suspend the cutting assembly 2, and the cutting assembly 2 is used to shear the waste edge of the sheet material. The support assembly 1 realizes the functions of angle adjustment and width adjustment of the edge cutting device, and the cutting assembly 2 realizes the function of timed cutting.

[0035] like Figure 2 As shown, the support assembly 1 includes a connecting plate 11, a support plate 12, an optical axis 13, a hanging square tube 14, a rotating seat 15, a screw rod 16 and a hand wheel 17.

[0036] One end of the connecting plate 11 is connected to the bracket, and the other end is connected to the hanging square tube 14; one end of the supporting plate 12 is connected to the hanging square tube 14, and the other end is connected to the screw rod 16. There are two supporting plates 12, which are installed at both ends of the screw rod 16, and a bearing is installed between the screw rod 16 and the supporting plate 12. There are two optical axes 13, and both the optical axis 13 and the screw rod 16 are installed on the rotating seat 15. There are two rotating seats 15, which are located at both ends of the optical axis 13 and the screw rod 16. The optical axis 13 and the screw rod 16 are parallel to the hanging square tube 14, and the two optical axes 13 are installed on both sides of the screw rod 16 respectively; a bearing seat is provided on the rotating seat 15, and both ends of the optical axis 13 are installed in the bearing seat, and one end thereof passes through the bearing seat and the supporting plate 12 to connect the hand wheel 17.

[0037] The hanging square tube 14 is suspended under the bracket through the connecting plate 11, and its position can be flexibly moved. The supporting plate 12 is hung on the hanging square tube 14, and its position can be flexibly moved left and right. The rotating seat 15 is used to fix the optical axis 13, and can rotate at the same time to adjust the angles of the two optical axes 13. The screw rod 16 controls the movement of the cutting component 2 on the optical axis 13. When the width of the sheet material is switched online, the screw rod 16 is shaken by the hand wheel 17 to drive the nut 28 of the cutting component 2 to adjust the position of the cutting component 2.

[0038] like Figure 3 As shown, the cutting assembly 2 includes a machine base 21, a knife base 22, a blade 23, a linear slider 24, a cylinder 25, an optical axis slider 26, a cover 27, a nut 28, a material guide port 29 and a time relay.

[0039] The machine base 21 is divided into two parts. One part is equipped with an optical axis slider 26, a nut 28 and a material guide port 29. The optical axis slider 26 cooperates with the optical axis 13 to form a moving pair, and the nut 28 cooperates with the screw 16 to form a moving pair, so that the machine base 21 can move horizontally on the support assembly 1. A material guide port 29 is provided between the nut 28 and the optical axis slider 26. The material guide port 29 is perpendicular to the blade 23 and is trumpet-shaped, with the smaller end close to the blade 23. The other part is equipped with a linear slider 24, a knife seat 22, a blade 23 and a cylinder 25. The blade 23 includes an upper blade 23 and a lower blade 23, both of which are installed in the knife seat 22. The upper blade 23 and the lower blade 23 form an acute angle, and the angle is adjustable. The linear slider 24 is located on both sides of the machine base 21, and the knife seat 22 is installed in the machine base 21 through the linear slider 24. The cylinder 25 is installed above the upper blade 23, and the output shaft of the cylinder 25 is connected to the upper blade 23. The cylinder 25 is connected to the time relay for communication, and the time relay controls the cylinder 25 to press the blade 23 to cut the sheet material. A cover 27 is installed on the front and rear surfaces of the base 21.

[0040] All parts of the cutting component 2 are installed on the machine base 21. The tool holder 22 is connected to the tool holder 22 through a linear slider 24. The blade 23 is divided into an upper blade 23 and a lower blade 23. The lower blade 23 has a horizontal cutting edge to facilitate the waste edge material to pass through the cutting opening. The upper blade 23 has an inclined opening and is installed on the tool holder 22. The movement of the tool holder 22 and the upper blade 23 is controlled by a cylinder 25. The machine base 21 is connected to the support component 1 through an optical axis slider 26. The nut 28 cooperates with the lead screw 16 of the support component 1 to adjust the position of the cutting component 2 on the optical axis 13. The material guiding opening 29 is a flared opening to guide the waste edge material to smoothly pass through the cutting edge opening. Cover shells 27 are installed at both the front and the back, making the appearance of the machine base 21 more beautiful and safer.

[0041] Under the traction of the production line itself, the sheet material enters the cutting device of the present invention. By adjusting the angle of the device, the waste edge can enter the cutting edge vertically to achieve the best cutting effect. The cylinder 25 is controlled by a time relay to press the blade 23 to cut the edge material. For different widths of sheet materials, the waste edge can also be adjusted to smoothly enter the material guiding opening 29 through the lead screw 16.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
