Canvas stretching and nailing device

Abstract

The invention discloses a canvas stretching and nailing device which comprises a bottom moving track, a clamping and pushing device and a stretching and nailing device, wherein the moving track pushes a canvas and a frame to the bottom of the clamping and pushing device, the canvas is delivered to an accommodating space between clamping jaws, a clamping cylinder drives the clamping jaws to clamp the edge of the canvas, a pushing cylinder pushes a pushing plate profile, the clamping cylinder moves along with the pushing plate profile, the clamping jaws wrap the edge of the canvas on the frame; a cylinder drives a heavy sliding block to drive an aluminium profile to move downwards, and a nail gun falls to the stretching and nailing position along with the aluminium profile, and stretches and nails the canvas on the frame. The device disclosed by the invention can automatically complete the process flows of wrapping the frame and stretching and nailing, realize uniform tightness of stretching and nailing, and ensure the levelness of stretching and nailing, thus improving the stretching and nailing efficiency and reducing investment of labor force.

Description

technical field [0001] The invention relates to the technical field of picture frame processing, in particular to a canvas nailing device for automatic nailing. Background technique [0002] The traditional method of stretching the canvas on the picture frame or board is by hand, or with the help of some simple tools. For example, the way of artificial stretching is that workers use stretching pliers to tighten the canvas before nailing. One nail requires the worker to tighten the canvas once, which is time-consuming and laborious to operate manually, and the tightness of the canvas stretching is inconsistent, making it difficult to meet the requirements. The traditional stretching method generally has problems such as poor quality of the frame, cumbersome process, low efficiency, and high labor costs. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a canvas stretching device. The nail...

[0002] The traditional method of stretching the canvas on the picture frame or board is by hand, or with the help of some simple tools. For example, the way of artificial stretching is that workers use stretching pliers to tighten the canvas before nailing. One nail requires the worker to tighten the canvas once. Manual operation is time-consuming and laborious, and the degree of tightness of the canvas stretching is inconsistent, so it is difficult to meet the requirements.

The traditional stretching method generally has problems such as poor quality of the frame, cumbersome process, low efficiency, and high labor costs.
