Printing machine with improved feeding device

Abstract

The invention relates to the technical field of printing equipment, in particular to a printing machine with an improved feeding device, which comprises a rack, and a push roller operates to feed printing paper in a containing groove into a printing station one by one for printing; push plates are installed on the two sides of the containing groove, the push plates are connected to the containing groove through springs, and the push plates are parts for fixing printing paper between the left push plate and the right push plate. A magnetic affinity material is installed on the push plate, a first electromagnet is arranged below the containing groove, the first electromagnet is connected with a power source through a time delay switch, and after the first electromagnet is powered on, the first electromagnet and the magnetic affinity material attract each other and enable the push plate to be positioned on the containing groove; the time delay switch is provided with a button, the button is installed below the containing groove, and the time delay switch is turned on when heavy objects exist on the containing groove. The printing machine has the advantages that the printing paper is not deformed when the printing paper is less, and the product quality is ensured; and the device has the advantage of higher automation degree.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printing machine. Background technique [0002] The printing machine includes a frame with a feeding device behind the frame, a printing station in the middle of the frame, and a printing assembly on the printing station. [0003] The raw material used by the printing machine is a whole stack of printing paper, and the feeding device is a component that feeds the printing paper into the printing assembly one by one. [0004] The feeding device includes a storage tank for printing paper, on which there is a push roller driven by a motor, and the operation of the push roller can feed the printing paper in the storage tank one by one into the printing station for printing. [0005] In order to ensure that the printing paper is in a definite position inside the holding tank, push plates are installed on both sides of the holding tank.

Problems solved by technology

[0005] In order to ensure that the printing paper is in a definite position inside the holding tank, push plates are installed on both sides of the holding tank. The parts between the push plates; when there is less printing paper between the push plates, due to the action of the spring, the printing paper between the push plates will be deformed under the action of the push plates (for example, the middle of the printing paper is bowed, that is, formed "⌒"), affecting the accurate entry of printing paper into the printing assembly, thereby affecting the quality of the product
