Barrier plate assembly of folding machine

Abstract

The invention discloses a barrier plate assembly of a folding machine, which comprises a short barrier plate, at least one long barrier plate and a pair of support plate, wherein each support plate is provided with a long barrier plate support face and a short barrier plate support face which are arranged in parallel, two sides of the long barrier plate are supported by a pair of long barrier plate support faces, two sides of the short barrier plate are supported by a pair of short barrier plate support faces, and each long barrier plate support face is provided with an extending section which extends upwards and is capable of reducing the overhanging quantity of the long barrier plate. Through adoption of the barrier plate assembly of the folding machine, the barrier plates can be positioned accurately and can be prevented from tilting and deforming, the overhanging vibration is reduced and the folding accuracy can be improved.

Description

technical field [0001] The invention relates to a folding machine, in particular to a folding machine fence plate assembly. Background technique [0002] In the prior art, the support plates in the fence plate assembly of the folio folder are roughly divided into two structures: one is a separate type, that is, each side of each fence plate is provided with an independent support plate, and each support plate is only There is a precisely machined supporting surface that can only support a single fence board. Although this structure is relatively simple, it is difficult to ensure the installation accuracy, that is, the parallelism of the upper and lower fence boards needs to be close to the upper and lower two. The parallelism between the supporting surfaces in the supporting plate is guaranteed, and the parallelism between the two supporting surfaces is completely guaranteed by the installation and assembly accuracy of the two supporting plates.

[0002] In the prior art, the support plates in the fence plate assembly of the folio folder are roughly divided into two structures: one is a separate type, that is, each side of each fence plate is provided with an independent support plate, and each support plate is only There is a precisely machined supporting surface that can only support a single fence board. Although this structure is relatively simple, it is difficult to ensure the installation accuracy, that is, the parallelism of the upper and lower fence boards needs to be close to the upper and lower two. The parallelism between the supporting surfaces in the supporting plate is guaranteed, and the parallelism between the two supporting surfaces is completely guaranteed by the installation and assembly accuracy of the two supporting plates. As we all know, the installation and assembly accuracy is difficult to control, and the random error is large. The positioning accuracy is also greatly affected; the other is the integral type, that is, two fence boards share a support plate on each side, and each support plate has two equal-length, precisely processed support surfaces, and each support surface is respectively A fence board provides support. Since the two supporting surfaces are on the same support board, the parallelism between the two can be guaranteed by machining, which makes the installation of the fence board effectively controlled, and the accuracy is stable and reliable. However, There are still two problems in the fence board assembly of this structure: 1. The lengths of the fence boards are not equal (the one on the upper side is a long fence board, and the one on the lower side is a short fence board), and the two fence boards on the support plate The lengths of the two supporting surfaces are equal, and the length of the supporting surface supported by the short fence board can meet the requirements, but the contact length between the long fence board and the supporting surface is less than half of the total length of the long fence board. According to the principle of leverage, the front end of the long fence board is easy to tilt. Or produce deformation, when the machine is working, the long fence board vibrates greatly due to the overhanging length, which affects the folding accuracy; 2. Since the contact length between the long fence board and the supporting surface is very short, the installation position of the eccentric handle is close to the upper surface of the supporting board , the distance between the eccentric handle and the end surface of the support plate is very short, which may easily cause the unreliable locking of the eccentric handle on the long fence plate and affect the folding accuracy
