Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing presses, and specifically relates to an anti-wrinkle printing press. Background Technology
[0002] A printing press is a machine that uses rollers to move paper and then applies ink to it after it passes through an inking roller. During the operation of a printing press, the paper may not be tightened during its journey, resulting in poor contact with the inking roller and affecting the uniformity of ink application. It may also cause the paper to wrinkle due to loosening after passing through multiple rollers. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an anti-wrinkle printing machine.
[0004] The purpose of this utility model can be achieved through the following technical solution: an anti-wrinkle printing machine, comprising two main boards, and a plurality of conveying rollers and inking rollers located between the two main boards, characterized in that a sliding shaft is provided between the two main boards, a tightening sleeve is provided on the sliding shaft, an arc-shaped groove for limiting the sliding shaft is provided on both main boards, a bearing groove is provided in the arc-shaped groove, a bearing is provided at both ends of the sliding shaft, the bearing is located in the bearing groove and can slide in the bearing groove;
[0005] A linkage rod is provided on the sliding shaft located between the arc-shaped groove and the tightening sleeve. One end of the linkage rod is connected to the sliding shaft, and a bushing is provided on the other end. Both main plates are provided with cylindrical bosses, and the bushing is fitted onto the cylindrical bosses.
[0006] In the aforementioned anti-wrinkle printing machine, a support plate is provided between the two main plates. The support plate has two through holes. A collar is provided on the linkage rod. A pull rod is provided on the collar, which can slide along the collar and has one end passing through the through hole. A limit part is provided at one end of the pull rod.
[0007] In the aforementioned anti-wrinkle printing machine, an elastic element is provided on the pull rod, one end of which is connected to the support plate and the other end is connected to the limiting part.
[0008] In the aforementioned anti-wrinkle printing machine, there are two of each of the following: linkage rod, collar, pull rod, limiting part, elastic element, and through hole, and they are arranged symmetrically.
[0009] Compared with existing technologies, this anti-wrinkle printing press straightens the paper through the conveying roller and the inking roller, and further straightens the paper through the tightening roller, reducing the occurrence of loose and wrinkled paper. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, this anti-wrinkle printing machine includes two main boards 1, and several conveying rollers 2 and inking rollers 3 located between the two main boards 1. A sliding shaft 4 is provided between the two main boards 1. A tightening sleeve 5 is provided on the sliding shaft 4. Both main boards 1 are provided with arc-shaped slots 6 for limiting the sliding shaft 4. A bearing groove 7 is provided in the arc-shaped slot 6. Bearings 8 are provided at both ends of the sliding shaft 4. The bearings 8 are located in the bearing groove 7 and can slide in the bearing groove 7.
[0016] A linkage rod 9 is provided on the sliding shaft 4 located between the arc-shaped groove 6 and the tightening sleeve 5. One end of the linkage rod 9 is connected to the sliding shaft 4, and the other end is provided with a bushing 10. Both main plates 1 are provided with cylindrical bosses 11, and the bushing 10 is fitted onto the cylindrical bosses 11.
[0017] A support plate 12 is provided between the two main boards 1. The support plate 12 has two through holes 13. A collar 14 is provided on the linkage rod 9. A pull rod 15 is provided on the collar 14, which can slide along the collar 14 and has one end passing through the through hole 13. A limit part 16 is provided at one end of the pull rod 15. An elastic element 17 is provided on the pull rod 15. One end of the elastic element 17 is connected to the support plate 12, and the other end is connected to the limit part 16.
[0018] During use, the paper passes between the conveyor rollers and then passes above or below the tightening roller. The specific support direction can be changed according to the printing requirements. When the paper comes into contact with the inking roller 3, it will be initially straightened by the conveyor roller 2 and the inking roller 3 during the paper's movement. During the straightening process, the tightening roller will move up or down. At the same time, the elastic element 17 will give the paper a restoring force in the opposite direction through elastic reset, so that the paper is further straightened.
[0019] Preferably, there are two of each of the following components: linkage rod 9, collar 14, pull rod 15, limiting part 16, elastic element 17, and through hole 13, which are arranged symmetrically.
[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0021] Although this document frequently uses terms such as main board 1, conveying roller 2, inking roller 3, sliding shaft 4, tightening sleeve 5, arc-shaped groove 6, bearing 8 groove 7, bearing 8, linkage rod 9, bushing 10, cylindrical boss 11, support plate 12, through hole 13, collar 14, pull rod 15, limiting part 16, and elastic element 17, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
