Abstract

The invention discloses a stretching machine. According to the technical scheme, the stretching machine is characterized in that the stretching machine comprises a machine frame and further comprises a fixed clamping seat, two side clamping seats and a movable clamping seat, wherein the fixed clamping seat is connected to the machine frame and provided with a plurality of first clamping hands; the two side clamping seats are slidably connected with the machine frame and perpendicular to the length direction of the fixed clamping seat and provided with second clamping hands; the machine frame is provided with a bidirectional transmission device driving the two side clamping seats to slide at the same time; the movable clamping seat, the fixed clamping seat and the two side clamping seats form a frame-shaped structure, and the movable clamping seat is provided with a third clamping hand; the movable clamping seat is connected with a driven mechanism, and the machine frame and the side clamping seats are provided with driving mechanisms for driving the driven mechanism to slide in the length direction of the side clamping seats. The three-side automatic stretching and tensioning structure is adopted, and machining efficiency is improved; and the side clamping seats are matched with a synchronous chain through driven keys on sliding sleeves, assembling is convenient, and overhaul and replacement are facilitated.

Description

technical field [0001] The invention relates to the field of screen processing equipment, in particular to a screen stretching machine. Background technique [0002] The screen stretcher is a special supporting auxiliary machine for screen printing plate making. It stretches the screen on the screen frame with a certain tension, and is an important equipment for the printing plate carrier. [0003] At present, the announcement number on the market is that the Chinese patent of CN103203963A discloses a kind of screen stretching device, is provided with some jacking cylinders below the screen, and jacking cylinder comprises the jacking bar that is connected with screen frame, according to jacking bar The expansion and contraction can achieve the effect of lifting or lowering the screen frame. [0004] However, in the above scheme, a large number of stretching units are used on the screen, each stretching unit includes a power drive mechanism, an elastic mechanism, and a stret...
