Description

Technical Field

[0001] The utility model relates to the technical field of material strip die cutting, in particular to an adjustable die cutting knife device. Background Art

[0002] In the processing of the material strip, according to the production process of the material strip, the material strip passes through the knife seat, first passes through the die-cutting roller and the die-cutting bottom roller, and the material strip is die-cut. The die-cutting bottom roller has a suction function, and the die-cut sheet is adsorbed on the die-cutting bottom roller and transported away as the die-cutting bottom roller rotates. The traditional die-cutting bottom roller realizes the suction function through a suction disk. When the traditional suction disk is installed, one end is against the side plate of the knife seat, and the other end is against the end face of one end of the die-cutting bottom roller. When the material strip processing requirements are high, the die-cutting bottom roller needs to be adjusted in the axial direction. Since the traditional die-cutting bottom roller cannot be adjusted in the axial direction, and both ends of the roller body of the traditional die-cutting bottom roller are installed on the support shaft through a connecting disk, the roller body is installed on the support shaft through the connecting disk, and is not an integrated arrangement. There is an installation gap between the suction disk and the connecting disk, which makes it possible to leak air during the suction process, so the traditional die-cutting bottom roller still has certain limitations.

[0003] Therefore, there is a need for an adjustable die cutting knife device that solves the above problems. Utility Model Content

[0004] The utility model provides an adjustable die-cutting knife device, which realizes the adjustment of the suction roller in the axial direction. At the same time, the suction roller and the rotating shaft are integrated, which reduces the installation gap between the suction plate and the suction roller, thereby reducing the air leakage between the suction plate and the suction roller.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The adjustable die-cutting knife device comprises a suction roller body, which is rotatably mounted on a knife seat, and a rotating shaft is provided at both ends of the suction roller body, and the suction roller body and the two rotating shafts are integrally arranged, and a suction disk is rotatably mounted on one of the rotating shafts, and one side wall of the suction disk is in contact with the end face of the suction roller body, and an axial adjustment gap is provided between the other side wall of the suction disk and the knife seat, and an adjustment component for adjusting the suction roller body in the axial direction is installed on the knife seat, and a pair of adjusting sliders are provided on the knife seat, each of the rotating shafts is rotatably mounted on the corresponding adjusting slider, and the adjusting component comprises an adjusting screw, and the adjusting screw is threadedly mounted on one of the adjusting sliders and fixedly rests on the end face of the corresponding rotating shaft.

[0007] As a preferred technical solution, the suction roller body is provided with a plurality of suction holes for adsorbing the sheet material, and the suction roller body is provided with a plurality of axial suction channels distributed in a ring shape, and each of the suction holes is connected to the corresponding axial suction channel.

[0008] As a preferred technical solution, the suction plate is provided with a suction groove for communicating with the axial suction channel, the suction groove is connected to a suction element, and the suction groove is arranged in an arc shape on the side wall where the suction plate and the suction roller are attached.

[0009] As a preferred technical solution, a rolling bearing is installed on the corresponding rotating shaft, the suction plate is installed on the rolling bearing, a thrust bearing is arranged on the suction plate, and the thrust bearing is arranged on the side wall where the suction plate and the suction roller are attached.

[0010] As a preferred technical solution, a positioning component for positioning the air suction plate is provided between the air suction plate and the knife seat, and the positioning component includes a connecting plate, one end of the connecting plate is mounted on the knife seat, and the other end of the connecting plate is connected to the air suction plate.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0012] Since the adjustable die-cutting knife device includes a suction roller body, when using the device, two adjusting sliders are installed between the two side plates of the knife seat, and the top of the adjusting screw rod is pressed against the end face of the rotating shaft by rotating the adjusting screw rod, so that the suction roller body is adjusted in the axial direction, so that the position of the suction roller body cooperates with the upstream and downstream roller bodies. After the position adjustment of the suction roller body is completed, the suction plate is positioned on the knife seat through the connecting plate, so as to prevent the suction plate from rotating with the rotation of the suction roller body. In the utility model, compared with the traditional positioning method of pressing the two sides of the suction plate against the side plates of the knife seat and the end faces of the suction roller body, an axial adjustment gap is provided between the suction plate and the adjusting slider in the device, and the suction roller body can be adjusted in the axial direction by rotating the adjusting screw rod, so that the device is suitable for high processing requirements. At the same time, the suction roller body and the rotating shaft are integrated, which reduces the installation gap between the suction plate and the suction roller body, thereby reducing the air leakage between the suction plate and the suction roller body.

[0013] Since the suction plate is provided with a suction groove, and the suction groove is arranged in an arc shape on the side wall of the suction plate, when the device is used, the suction plate is connected to the knife seat by the connecting plate, the suction plate does not rotate, and the suction holes connected with the suction groove through the axial suction channel perform suction work, and the suction holes not connected with the suction groove do not perform suction work. Therefore, with the rotation of the suction roller body, the axial suction channel on the suction roller body is continuously connected and disconnected with the suction groove, thereby realizing intermittent suction operation of the suction holes.
