Canvas stapling machine

Abstract

The invention relates to a canvas stapling machine. The canvas stapling machine can tighten a canvas surface on the front side of a frame and can staple canvas edges on the back side of the frame. The canvas stapling machine is characterized by comprising limiting parts and an even number of groups of clamping parts, wherein each group of clamping parts correspond to one group of limiting parts; two groups of oppositely arranged limiting parts can limit the frame covered with canvas in the center, every two groups of clamping parts are oppositely arranged on the back side of the frame, and each group of clamping parts correspond to one edge of the frame; two groups of oppositely arranged clamping parts can move in the opposite directions, and / or the frame can move in the direction pointing to the front side of the frame; in the two groups of oppositely arranged clamping parts, at least one group of clamping parts are further correspondingly provided with one group of pressing parts, and the pressing parts can be pressed together with the side surface of the frame in the opposite directions; each group of clamping parts are further correspondingly provided with one group of shifting parts, and the shifting parts can move to the back side of the frame from the outer side of the frame; staple guns are further arranged on the back side of the frame.

Description

technical field [0001] The invention relates to a canvas binding device, in particular to a cloth stapler. Background technique [0002] The canvas needs to be bound on the picture frame to facilitate painting. Generally, the canvas is covered on the front of the frame as a whole, and then the four sides of the canvas wrap around the edge of the frame and turn over to the edge of the back of the frame. most Finally, nail the edge of the canvas to the edge of the back of the frame with a nail gun. [0003] When the canvas is bound to the picture frame, it is generally bound by hand or with the help of a nail gun. Before binding, the operator also needs to manually tension the canvas on the picture frame, and then bind it. But no matter what kind of binding method, because the binding process is a manual or semi-automatic way to bind the canvas, the binding speed is slow and the time is long, which increases the production cost of the oil painting and reduces the production ...

AI Technical Summary

Problems solved by technology

But no matter what kind of binding method, because the binding process is a manual or semi-automatic way to bind the canvas, the binding speed is slow and the time is long, which increases the production cost of the oil painting and reduces the production efficiency. At the same time, it is bound by hand, and the nails bound on the picture frame are not neat and firm enough, and the binding effect is not very good

[0004] Moreover, the cost of canvas accounts for a large proportion in the entire product. During the binding process, when the canvas is tensioned with clips, the canvas held by the clip is basically wasted.
