Problems solved by technology

[0003] When the current laser punching machine is running, the distance between the hole and the edge of the paper may change, and this change is extremely difficult to detect on high-speed paper
However, the traditional method of measuring with a ruler has a large measurement error because it cannot touch the high-speed running paper.

Abstract

The invention relates to the technical field of punching and rewinding of web-loaded paper, and in particular to a laser projection type non-contact margin measuring instrument comprising the following parts including a base; a track connected to the base; a guide rail slider A in sliding connection with the track; a guide rail slider B in sliding connection with the track; an adjustable screw A connecting the base and guide rail slider A; an adjustable screw B connecting the guide rail slider A and the guide rail slider B; a laser head A connected to the guide rail slider A; a laser head B connected to the guide rail slider B, wherein a connection line between the laser point B emitted by the laser head B and the laser point A emitted by the laser head A is parallel to the moving direction of the guide rail slider A on the track; a distance measuring reflection table A connected to the guide rail slider A; a distance measuring reflection table B connected to the guide rail slider B; and a laser distance measurement instrument. The margin measuring instrument provided by the application has the advantages of non-contact, high distance measurement accuracy and simple operation.

Description

Technical field [0001] The invention relates to the technical field of perforating and rewinding narrow-width tipping paper, in particular to a laser projection type non-contact margin measuring instrument. Background technique [0002] The laser perforating machine is used to perforate tipping paper, which increases the air permeability of the paper by using a certain frequency of laser to ablate pores on the paper conveyed at high speed. [0003] The distance between the hole and the edge of the paper may change when the current laser punching machine is in operation. This change is extremely difficult to detect on the high-speed paper. However, the traditional way of measuring with a ruler causes a large measurement error because it cannot touch the high-speed paper. Therefore, there is a need for a measurement tool that can maintain measurement accuracy without directly touching the paper. Summary of the invention [0004] Aiming at the problems existing in the prior art, the ...
