Description

Cord fabric cutting device and joint avoiding cutting system Technical Field The utility model relates to the technical field of cutting devices, in particular to a curtain cloth cutting device and a joint avoiding cutting system. Background Cord fabric is one of the main raw materials for producing air springs, and in the feeding process, cord fabric rolls are usually required to be cut into block structures of parallelogram structures. The inclination angles of the curtain cloth blocks required in the production of the air springs of different types are different, so that the angle of the cutter needs to be adjusted in the cutting process. The existing cutter inclination angle adjusting modes are various, for example, the text record of an automatic joint coiling device for cutting an angle fiber curtain cloth is disclosed in China publication No. CN114103210B, adjusting tracks are arranged on two sides of a conveying belt to realize the angle adjustment of the cutter along the tracks, and the text record of a tire curtain cloth cutting and feeding device is disclosed in China publication No. CN215970215U, and the angle of the cutter is adjusted by adopting a swing arm type structure. However, in the adjusting mechanism described in the cited patent, the axial position of the angle adjustment of the cutter is not limited, and when the rotational axial position of the cutter is not proper, it is difficult to realize the cutter angle adjustment with the minimum swing width. In addition, because the length is limited in the production process of the curtain cloth, a plurality of strip-shaped curtain cloth are often lapped with each other and then wound into a large curtain cloth feeding roll, so that the curtain cloth can be continuously fed for a long time in the preparation process of the air spring. In the conventional cutting device, most of the cord fabric rolls are continuously cut at equal intervals according to the width value of the cord fabric block required by each batch in the cutting process, so that if the cutting position of the previous cord fabric block is very close to the joint in the cutting process, the cutter still moves to a designated distance and then begins to cut, and the cord fabric cannot be cut at the position of the cord fabric joint, which is close to the joint, by the cutter after the cord fabric joint passes through the cutter, thereby causing a great deal of waste of the cord fabric materials. Obviously, aiming at automatic cutting equipment, if a curtain cloth connector is required to be cut by being close to the curtain cloth connector after passing through a cutter, the axial position of the angle adjustment of the cutter is selected at an improper time, the distance between the cutter and the curtain cloth connector is difficult to calculate after the inclination angle adjustment of the cutter, and then the cutting time of the cutter cannot be accurately judged, so that the curtain cloth material waste is easily caused, and the problem is to be solved. Disclosure of utility model In order to avoid and overcome the technical problems in the prior art, the utility model provides the curtain cloth cutting device and the joint avoiding cutting system, and the rotation axis position of the cutting angle adjustment of the cutter is optimized, so that a technical platform is provided for controlling the accurate interval between the cutter and the curtain cloth joint, so that the curtain cloth is cut immediately adjacent to the curtain cloth joint after the curtain cloth joint passes through the cutter, and the waste of curtain cloth materials is reduced. In order to achieve the above purpose, the present utility model provides the following technical solutions: The curtain cloth cutting device comprises a belt conveying mechanism, wherein a cutter assembly for cutting curtain cloth is arranged above the belt conveying mechanism, the cutting angle of the cutter assembly is adjustable along a rotation axis, the rotation axis is distributed along the plumb direction, and the rotation axis is positioned on the central axis of the curtain cloth. The cutting device further comprises a traction mechanism for traction of the cut curtain cloth pieces and moving of the curtain cloth pieces to the conveying rear end of the belt conveying mechanism, the traction mechanism comprises a rotating rod which is horizontally distributed, at least two traction sucking discs are distributed at the bottom of the rotating rod along the length direction of the rotating rod, the angle of the rotating rod is adjustable along a rotating axis, the rotating axis is distributed along the vertical direction, and the rotating axis is located on the central axis of the curtain cloth. As a still further scheme of the utility model, the belt conveyor is fixedly provided with the track rods distributed along the central axis of the belt conveyor, the rotating rods slide on the rod bodies of the track rods throu
