Canvas tightening machine of painting frame

Abstract

The invention relates to a processing device of a painting frame, in particular to a canvas tightening machine of a painting frame. A rack comprises an upper-layer rack body and a lower-layer rack body. Feeding sliding ways are arranged on the lower-layer rack body and provided with a feeding tray moving along the feeding sliding ways. The positions, on the two sides of the feeding sliding ways, of the lower-layer rack body are each provided with a nail gun sliding way. A nail gun frame moving along the nail gun sliding ways is arranged on the nail gun sliding ways. The nail gun frame is connected with a moving pneumatic cylinder. Nailing guns are arranged and mounted on the nail gun frame and connected with nailing pneumatic cylinders. The upper portions of the positions, corresponding to the two sides of the painting frame, of the upper-layer rack body are each provided with a clamp plate for clamping a canvas. Two clamping plates of each clamp plate are connected with clamping pneumatic cylinders. Tightening pneumatic cylinders are connected between the two clamp plates. According to the canvas tightening machine of the painting frame, operations of tightening, clamping and automatic nailing of the canvas and the painting frame can be achieved at a time, the tightness degree of the canvas is increased and is uniform, and the ideal requirement of a painter can be met; and production cost and manual input are greatly reduced, production efficiency is improved, and operation is easy and fast.

Description

technical field [0001] The invention relates to a processing device for a picture frame, in particular to a picture frame stretcher. Background technique [0002] In the prior art, to stretch the picture frame, the workers use stretching pliers to tighten the canvas and then nail it. Every time a nail is nailed, the worker needs to tighten the canvas once. The manual operation is time-consuming and laborious. After the drawing board is stretched The tightness is uneven, and it is difficult to meet the painter's requirements. Traditional picture frames have low production efficiency, high production cost and poor quality. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a picture frame stretcher, which adopts the following technical scheme: [0004] A picture frame stretcher, including a frame, which is divided into upper and lower layers, including an upper frame and a lower frame; [0005...
