Description

Technical Field

[0001] The utility model belongs to the technical field of picture frame conveying equipment, in particular to a picture frame direction adjusting mechanism. Background Art

[0002] The four sides of the existing back-mounted picture frame are fixed into a whole. In the right-angle grooves on the four sides of the frame behind the picture frame, the glass is first placed, then one of the calligraphy and painting charts is placed, and finally the back plate is installed. There are movable pins on the four frames behind the picture frame to block the back plate, or the back plate can be nailed directly to the back of the picture frame with small nails.

[0003] In our company, the degree of automation in picture frame assembly is low. In order to improve the degree of automation, our company has designed an automatic binding device. As a supporting device, our company has designed a picture frame conveyor line. Since picture frames come in square and rectangular sizes, there is no need to pick the edges when conveying squares; but when conveying squares, the long and short edges will be picked. When the picture frame needs to be adjusted, a direction adjustment mechanism needs to be designed. Utility Model Content
