Tensioning device for screen printing machine

Abstract

The invention discloses a tensioning device for a screen printing machine. The technical scheme of the device is characterized by comprising a machine frame, a printing device and a drying device; themachine frame is further provided with a printing tensioning mechanism and a drying tensioning mechanism; the printing tensioning mechanism comprises a tensioning roller and a tensioning motor, wherein the tensioning roller is used for allowing a strip-shaped material to be wound therearound, and an output end of the tensioning motor is provided with a magnetic powder clutch used for driving thetensioning roller to maintain the constant tension of the strip-shaped material; and the drying tensioning mechanism comprises a gravity tensioning frame capable of tensioning the strip-shaped material wound around the tensioning roller under the action of gravity, wherein the gravity tensioning frame is located at a feeding end of the drying device, one end of the gravity tensioning frame is rotationally connected to the machine frame, the other end of the gravity tensioning frame is provided with a gravity roller, and the gravity tensioning frame can maintain the strip-shaped material woundaround the tensioning roller in a tensioned state through the gravity roller under the action of gravity in the process of axially rotating around the machine frame. The tensioning device can keep thestrip-shaped material automatically tensioned, so that the printing effect and the drying effect of the strip-shaped material are improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, more specifically, it relates to a tensioning device for a silk screen printing machine. Background technique [0002] The silk screen printing machine is a tool for printing text and images. Its working principle is: the printed text and images are made into a printing plate, installed on the printing machine, and then the machine applies ink or solder paste to the printing plate with text and images, directly or indirectly transferred to paper, non-woven fabrics, metal plates, plastics, leather, wood, glass, ceramics, or other substrates to produce the same print as the printing plate. [0003] Existing silk screen printing machine can comprise the feed motor that is used for feeding, and is positioned at the discharge end of printing machine and is used for the stretching motor that the strip material of printing machine is tensioned, and the material receiving motor that is used fo...

Problems solved by technology

[0003] Existing silk screen printing machine can comprise the feed motor that is used for feeding, and is positioned at the discharge end of printing machine and is used for the stretching motor that the strip material of printing machine is tensioned, and the material receiving motor that is used for receiving material, for To ensure that the strip material can be kept tensioned and conveyed smoothly, usually each motor is set as a synchronous motor, and even if the speed of each motor can be kept the same, due to the tension of the strip material during printing and the The tension during drying cannot be completely consistent, which will affect the printing effect and drying effect of the strip material
