Adjustable support for packaging printing machine

Abstract

The invention discloses an adjustable support for a packaging printing machine. The adjustable support comprises rotating bases and fixed lantern rings, wherein a telescopic rod rotating base is welded to one side surface of one of the rotating bases; a first telescopic rod is welded to the top surface of the telescopic rod rotating base; a support rod is welded to one side of the top surface of the first telescopic rod; the outer surface of the support rod is connected with the fixed lantern rings in a sleeving manner; and a corresponding fixed baffle plate is welded to one end of each of thefixed lantern rings. According to the adjustable support for the packaging printing machine disclosed by the invention, the rotating bases are arranged and can be rotated at 360 degrees; each of therotating bases have a corresponding detachable structure, so that the rotating bases are conveniently detached and mounted by an operator; the first telescopic rod and a second telescopic rod are driven by the rotating bases so as to be rotated at a certain angle, so that an angle between the support rod and a conveying surface is adjusted; and because the support rod passes through a packaging printing paper roller, the angle of the packaging printing paper roller is also adjusted when the support rod is adjusted at the same time, and the operator conveniently and reasonably controls stressedtension force of packaging printing paper so as to protect the packaging printing paper from being damaged.

Description

technical field [0001] The invention relates to the technical field of packaging printing machines, in particular to an adjustable bracket of a packaging printing machine. Background technique [0002] Before the 1950s, the traditional letterpress printing process dominated the printing industry, and the development of printing machines was also dominated by letterpress printing machines. However, the lead alloy letterpress printing process has the disadvantages of high labor intensity, long production cycle and environmental pollution. Disadvantages: Since the 1960s, the lithographic offset printing process with the characteristics of short cycle and high productivity began to rise and develop, and lead alloy letterpress printing was gradually replaced by lithographic offset printing, soft letterpress printing, stencil printing, electrostatic printing, inkjet printing, etc. Packaging printing and advertising printing have also been developed.

Problems solved by technology

[0002] Before the 1950s, the traditional letterpress printing process dominated the printing industry, and the development of printing machines was also dominated by letterpress printing machines. However, the lead alloy letterpress printing process has the disadvantages of high labor intensity, long production cycle and environmental pollution. Disadvantages: Since the 1960s, the lithographic offset printing process with the characteristics of short cycle and high productivity began to rise and develop, and lead alloy letterpress printing was gradually replaced by lithographic offset printing, soft letterpress printing, stencil printing, electrostatic printing, inkjet printing, etc. Packaging printing and advertising printing have also been developed

[0003] The packaging printing machine prints the packaging materials. Among the various packaging materials, most of the packaging materials are in the shape of round rolls, so a support is needed to support them for printing and feeding, and most of the support The structure cannot be adjusted, which often leads to unreasonable feeding of packaging materials. At the same time, it cannot be used universally when facing different types of packaging material round rollers, which brings a lot of inconvenience to production. Therefore, an adjustable support for packaging printing machines is needed to solve the above problems. question
