The implementation principle of the semi-automatic picture frame canvas binding all-in-one machine is as follows: after the canvas on one side is bound, the connecting folded plate 4 is moved, so that the canvas edge clamping mechanism 65 is moved to the edge position of the picture frame, the lifting cylinder 5 is started, the lifting cylinder 5 drives the pre-pressing block 602 and the connecting transverse plate 643 to move downwards, the connecting transverse plate 643 is propped against the back surface of the picture frame and applies pressure to the picture frame, and the picture frame can be placed on the workbench 1 relatively fixedly.
Referring to fig. 10, the canvas is clamped by using the canvas edge clamping mechanism 65, and then the traversing cylinder is started to enable the traversing cylinder to push the second supporting beam 603 to move, the canvas edge clamping mechanism 65 drives the canvas to move, and the canvas is subjected to force in the f2 direction, so that the position of the picture frame is relatively fixed, the canvas moves, the canvas can be automatically tensioned, and a worker binds the canvas by using a nail gun, so that the fixing of the canvas can be realized.
The frame pushing mechanism in this embodiment may be implemented by an equivalent concept, for example, the two sides of the frame are clamped to implement positioning, and any structure capable of positioning the frame is within the scope defined in this embodiment.
Example 3:
referring to fig. 11, the difference from embodiment 1 and embodiment 2 is that a traveling device 9 is provided on the connection flap 4, and the traveling device 9 can drive the connection flap 4 and the second slider 3 to automatically travel on the guide rail 11, so that the connection flap 4 can drive the entire movable tension frame 6 to travel. The running gear 9 includes a jack-back cylinder 91 hinged with the connecting folded plate 4, a piston rod of the jack-back cylinder 91 is inclined downwards towards the table surface of the workbench 1, and the inclined direction of the piston rod is away from the working area. The end of the piston rod is fixedly connected with a butt joint 92, and the butt joint 92 can be made of rubber products.
According to the scheme, when the walking device 9 is arranged on the connecting folded plate 4, and the walking device 9 is arranged, after a worker binds a picture frame, the position of the movable tensioning frame 6 on the workbench 1 is adjacent to one side of the worker, the movable tensioning frame 6 can be directly pushed, and under the action of pushing force, the connecting folded plate 4 drives the movable tensioning frame 6 to walk towards the other side of the workbench 1, namely the movable tensioning frame 6 walks towards one side of the positioning device 2 of the picture frame. When the movable tensioning frame 6 is needed to be used by a worker, the movable tensioning frame 6 is not required to be pushed back to the other side of the workbench 1, the jack-back cylinder 91 is only required to be started, the jack-back cylinder 91 can rapidly drive the abutting joint 92 to abut against the workbench 1 to generate reverse thrust, and therefore the movable tensioning frame 6 is driven by the connecting folded plate 4 to reset, and the movable tensioning frame is convenient for the worker to use.
The two running devices 9 can be arranged, the inclination directions of the two running devices 9 are opposite, the movable tensioning frame 6 can slide back and forth in the horizontal direction, in the operation process, when the movable tensioning frame 6 is required to displace, the running devices 9 are directly driven to run by an electric mode, the movable tensioning frame 6 can slide automatically in two directions, and the automation and the production efficiency are improved.
The specific running gear 9 in the present embodiment may also adopt other equivalent means, for example, directly pushing the connection flap 4 by using an air cylinder, or driving the abutment 92 to abut against the table 1 by using other driving means, and the like, as long as the structure for generating the reverse driving force of the connection flap 4 is within the scope defined in the present embodiment.
