Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing, and particularly relates to a fixed-length cutting device for sheet processing. Background Art

[0002] During industrial processing, sheets of different sizes are required as needed, which requires cutting the sheets of fixed size. The current processing methods generally include manual cutting and using a sheet cutting machine, etc.

[0003] For example, Chinese Patent Application CN113661256A discloses a device for cutting a sheet, including a cutting chamber with an inlet and an outlet, the cutting chamber being configured to accommodate at least a part of the sheet located on a plane; a cutting device adapted to cut the sheet in the cutting chamber; and a control unit configured to control the device, including at least one closing element at the inlet or outlet of the cutting chamber, the closing element being movable between an open position and a closed position, in the open position, at least a part of the closing element is at a first distance from the plane of the sheet, in the closed position, at least a part of the closing element is at a second distance from the plane, the second distance being less than the first distance, the distance being measured along a direction substantially orthogonal to the plane in which the sheet lies. In the case of using a conveyor belt, the distance is measured along a direction substantially orthogonal to the forward direction.

[0004] However, there is a kind of automobile radiator fin, which is adhered by a double-sided adhesive sheet during installation, so it is necessary to cut the double-sided adhesive sheet into a size suitable for the use of the automobile radiator fin. When the device for cutting the sheet cuts the double-sided adhesive sheet, the double-sided adhesive sheet with adhesiveness at the bottom will stick to the conveyor belt of the device, resulting in the inability to complete cutting or output, and the residual adhesive will stick to the cutting knife due to cutting the double-sided adhesive sheet, affecting the subsequent cutting tooling.

[0005] Based on this, the utility model designs a fixed-length cutting device for sheet processing to solve the above problems. Summary of the Utility Model

[0042] The conveying assembly 22 includes a conveying shaft 221, a conveying wheel 222 and a conveying belt 223. Two conveying wheels 222 and two conveying belts 223 are provided. The conveying shaft 221 is located on the right side of the rotating shaft 214. The front and rear ends of the conveying shaft 221 are rotatably connected to the front plate 13 and the rear plate 12 respectively. The two conveying wheels 222 are coaxially fixedly installed on the conveying shaft 221. Grooves for cooperating with the conveying belts 223 are provided on the conveying wheels 222 and the rotating shaft 214. The two conveying wheels 222 are connected to the rotating shaft 214 through two conveying belts 223. The radius of the conveying wheel 222 is smaller than the radius of the rotating shaft 214.

[0043] The output component 23 includes an output shaft 231, output wheels 232, and a blower 233. There are three output wheels 232. The front and rear ends of the output shaft 231 pass through the right synchronous wheel of the first pulley component 213 and are rotatably connected to the front plate 13 and the rear plate 12. The output shaft 231 is fixedly connected to the right synchronous wheel of the first pulley component 213. The three output wheels 232 are evenly distributed between the right synchronous wheels of the two first pulley components 213. The output wheels 232 are fixedly connected to the output shaft 231.

While restricting the position of the double-sided adhesive sheet material, the roller 215 further drives the double-sided adhesive sheet material to move. Since the entire double-sided adhesive sheet material is only adhered to the two conveyor belts 223, when the double-sided adhesive sheet material moves to the right end of the conveying wheel 222, the blower 233 blows the double-sided adhesive sheet material upward.
