Groove positioning device

Abstract

The invention relates to the technical field of printing equipment accessories, particularly to a groove positioning device of a printing device. The conventional printing device fails to distinguish the groove position, causing labels printed on the groove unclear and imperfect. The groove positioning device comprises a steel pipe to be printed, an ink area and a printing motor. The lateral ends of the steel pipe to be printed are provided with V-shaped positioning blocks. A double cylinder is arranged under the V-shaped positioning blocks. On the ink area, a shaft where a printing gear exists is provided with a groove positioning rotating gear. One side of the groove positioning rotating gear is provided with a groove positioning servo motor which is connected with the groove positioning rotating gear through a synchronous belt. The other side of the groove positioning rotating gear is provided with a groove positioning sensor. The groove positioning rotating gear is internally provided with a bearing. The groove positioning device has the advantages that the structure is improved, product printing pass percent is increased, reworking time is shortened, labor waste is avoided, positioning device is of high operational stability, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment accessories, in particular to a groove positioning device. Background technique [0002] The existing printing device is to place the two ends of the steel pipe to be printed on two V-shaped positioning blocks (the V-shaped positioning block is actually two small runners plus two bearings, and the steel pipe can rotate smoothly on it, which can It acts as a driven wheel), and two double-connected cylinders are connected under the V-shaped positioning block. The ink area is composed of an oil filling wheel, a label fixing wheel and a printing wheel. When the cylinder lifts the steel pipe on the V-shaped block Finally, the surface of the steel pipe is in contact with the printing wheel. At this time, the rotation of the servo motor can drive each wheel in the ink area to rotate. The rotation of the oil filling wheel can add ink to the label surface, and the rotation of the label fixed whe...

[0002] The existing printing device is to place the two ends of the steel pipe to be printed on two V-shaped positioning blocks (the V-shaped positioning block is actually two small runners plus two bearings, and the steel pipe can rotate smoothly on it, which can It acts as a driven wheel), and two double-connected cylinders are connected under the V-shaped positioning block. The ink area is composed of an oil filling wheel, a label fixing wheel and a printing wheel. When the cylinder lifts the steel pipe on the V-shaped block Finally, the surface of the steel pipe is in contact with the printing wheel. At this time, the rotation of the servo motor can drive each wheel in the ink area to rotate. The rotation of the oil filling wheel can add ink to the label surface, and the rotation of the label fixed wheel can remove the ink on the label surface. Print on the printing wheel, so that the printing wheel can print the label on the surface of the steel pipe, but there is a groove on the surface of the steel pipe protruding from the surface of the steel pipe, and the printing device cannot distinguish the position of the groove, so the label printed on the groove is not very clear. The whole label is not perfect, and sometimes needs to be reworked, which seriously affects the production capacity, wastes manpower, and the production efficiency cannot be maximized
