Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printer printing paper adjustment, in particular to an inkjet printer printing paper angle adjustment mechanism. Background Art

[0002] An inkjet printer is a device that uses software control and non-contact methods to mark products. An optical inkjet printer can mark various texts, serial numbers, product numbers, barcodes, QR codes, production dates, etc. on non-metallic products, printed paper, etc., and the time, date or serial number, product number can automatically jump. The text and graphics of the inkjet printer are not only clear, but also cannot be erased or modified. This is very beneficial for tracking product quality and channels, and can effectively prevent the sale of expired products, prevent counterfeiting, and prevent mixed goods.

[0003] However, when using traditional inkjet printers, a thick stack of printing paper is usually placed on a roller to transport the printing paper. This method is usually prone to jamming and needs to be repaired, which not only wastes and reduces the efficiency of inkjet printing, but also may produce a lot of unqualified products during the jammed inkjet printing process. For this reason, we propose a paper angle adjustment mechanism for inkjet printers. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a printing paper angle adjustment mechanism for a printer. A first driving component drives a lead screw to rotate. The rotation of the lead screw drives the slide box to move under the action of the first pulley, the second pulley and the first belt, so that the two lead screws rotate. The rotation of the lead screw drives the slide box to move. The slide box moves forward and backward to drive the slide plate and the support column to move. Since the inclined plate is higher on the left and lower on the right, under the limiting action of the inclined plate, the slide plate and the support column not only move forward and backward, but also move up and down. When the support column resists the adjustment plate and rotates upward counterclockwise, the support column will also move upward. When the support column When the support column contacts the adjustment plate and rotates downward clockwise, the support column will also move downward, which can not only enhance the supporting effect of the support column on the adjustment plate and effectively increase the stability of the adjustment mechanism, but also can adjust the angle of the adjustment plate according to the amount and thickness of the printed paper. When the amount of printed paper is large and the thickness is thick, the angle between the adjustment plate and the second groove can be increased to reduce the friction force of the conveying component conveying a piece of printed paper, effectively avoiding the heavy printed paper from making the conveying component unable to convey the printed paper one by one, thereby improving the printing machine's paper conveying efficiency and conveying effect, and can effectively solve the problems in the background technology.
