Semi-automatic painting tightening machine

Abstract

The invention relates to the technical field of frame painting assembly, and discloses a semi-automatic painting tightening machine. The semi-automatic painting tightening machine comprises a machining table. Tightening mechanisms are symmetrically mounted on the machining table, and a fixing mechanism is mounted in the middle of the machining table. Each tightening mechanism comprises two limiting plates, multiple clamping grooves, a tightening plate, a through hole, a sliding hole, two sliding rods, two clamping rods, a spring and two clamps, wherein the two limiting plates are fixedly connected to the top side wall of the machining table symmetrically, the multiple clamping grooves are symmetrically formed in the opposite side walls of the two limiting plates, the tightening plate is arranged between the two limiting plates, the two clamps are fixedly connected to the opposite side walls of the two tightening plates symmetrically, the through hole is formed in the tightening plate,the sliding hole is formed in the hole wall, away from the clamps, of the through hole, and the two sliding rods are slidingly connected into the sliding hole symmetrically. According to the semi-automatic painting tightening machine, canvas can be conveniently tightened, meanwhile, inner frames of different types can be conveniently fixed, and then frame paintings can be conveniently assembled.

Description

technical field [0001] The invention relates to the technical field of frame painting assembly, in particular to a semi-automatic stretch painting machine. Background technique [0002] The frame painting includes the inner frame and the canvas. When assembling, place the inner frame under the canvas and tighten the canvas, and then use painting nails to nail the canvas to the inner frame. When assembling, the canvas needs to be applied manually. The tension makes the canvas taut, and then the painting nails are manually nailed between the canvas and the inner frame, which is not convenient for the assembly of the framed painting. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a semi-automatic stretching machine, which has the advantages of being easy to stretch the canvas, and at the same time, it is convenient to fix different types of inner frames, and further facilit...
