Abstract
A paper pressing frame lifting-up device is characterized by comprising a paper pressing frame, a swing rod, a connecting rod, a bent connecting rod, a support column, a cylinder and a fixing column. A working method includes the processes of paper pressing frame lifting up and paper pressing frame lifting down. The paper pressing frame lifting-up device has the advantages that the paper pressing frame lifting-up device is simple in structure, convenient to manufacture and low in cost; when the paper pressing frame is lifted up, and after the support column enters a groove position of a groove in the bend connecting rod, the support column forms dead point support on the left side of a connection line of the axes of a rotating shaft VI and a rotating shaft I, the paper pressing frame cannot fall down under the action of external force according to a dead point principle, and potential risk is reduced; a mounting mode is simple, and operation is facilitated; labor intensity is low, and safety factor is high.
Description
(1) technical field:
The present invention is applicable to printing mechanism, especially a kind of press frame uplifting device and method of work thereof.
(2) background technology:
Press frame is the framework that paper pressing devices such as pressure roller are installed, and is positioned at before paper-feeding part and cross cutting or the portion such as gold stamping.When paper-feeding part is continuously sent paper, paper pressing devices such as several groups of pressure rollers need be installed at defeated paper platform, when the paper of carrying not simultaneously, the layout of paper pressing device is also different, be head it off, common way in the industry is above the paper platform press frame to be installed defeated, and the paper pressing device clamping on press frame, is adjusted the clamping position of paper pressing device according to the paper needs.
Under equipment normal operation situation, the paper that paper pressing device is sent paper-feeding part is pressed attached, makes paper be delivered to next station in order, when states such as random of delivery platform appearance or paperboard, press frame need be lifted, artificially with jam cleaning sometimes.The press frame of prior art lifts, and to be that armrest is moving lift, and manually falls after having cleared up paperboard, it hooked again.When the paper breadth was big, the paper pressing device quantity of clamping was more on the press frame, artificially press frame was lifted and can require great effort very much, and press frame damages the personnel that carry out the paper cleaning work because deadweight plunks down very much greatly easily in addition.
(3) summary of the invention:
The object of the invention is to provide a kind of press frame uplifting device and method of work thereof, and it utilizes the dead point principle of connecting rod to realize auto-lock function, and not because the external force maloperation falls midway, this apparatus structure was simple after the realization press frame lifted, and labour intensity is low, and is safe and reliable.
Technical scheme of the present invention: a kind of press frame uplifting device is characterized in that it is made of press frame, fork, connecting rod, curved rod, pillar stiffener, cylinder and fixed leg; Described press frame one end is connected according to rotating shaft I revolute pair with wallboard, and the other end is connected with fixed leg; There is fixed leg hook groove the upper end of described fork, and the lower end is connected according to rotating shaft III revolute pair with wallboard; Described fixed leg places in the fixed leg hook groove; One end of described connecting rod is connected with the bottom revolute pair of fork, and the other end is connected according to rotating shaft IV revolute pair with an end of curved rod; The other end of described curved rod is connected according to rotating shaft VI revolute pair with the cylinder body of cylinder, has groove on the curved rod, and the middle part of curved rod is connected according to rotating shaft V revolute pair with wallboard; Described rotating shaft V is between rotating shaft IV and groove; Piston one end of described cylinder is connected according to rotating shaft II revolute pair with the middle part of press frame; Described pillar stiffener is positioned at the groove below, captives joint with wallboard.
A kind of method of work of above-mentioned press frame uplifting device is characterized in that concrete steps are as follows:
(1) press frame lifts process: the cylinder ventilation, piston stretches out, curved rod V around the shaft clockwise rotates, connecting rod drive fork III around the shaft clockwise rotates, fixed leg hook groove is right pendulum thereupon, and fixed leg and fixed leg hook groove break away from, and the left end of press frame loses constraint, under the thrust of the piston of cylinder, press frame I around the shaft clockwise rotates; When curved rod turns to after pillar stiffener enters in the groove, curved rod stops operating, and pillar stiffener is in the left side of the axial connecting line of rotating shaft VI and rotating shaft II, and pillar stiffener provides support power to cylinder, and cylinder piston continues to stretch out until finishing whole piston stroke;
(2) press frame puts down process: the cylinder venting, piston-retraction, at the pulling force of cylinder piston and under the effect of gravity, press frame I around the shaft rotates counterclockwise, and when the line that goes to rotating shaft II and rotating shaft I and defeated paper platform plane parallel, piston continues retraction, curved rod V around the shaft rotates counterclockwise, connecting rod drive fork III around the shaft rotates counterclockwise, and fixed leg hook groove is left side pendulum thereupon, and the fixed leg of whereabouts enters in the fixed leg hook groove.
Preceence of the present invention is: (1) is simple in structure, and is easily manufactured, with low cost.(2) lift when press frame, after pillar stiffener entered in the groove position of the groove in the curved rod, pillar stiffener formed the dead point and supports in the left side of the axial connecting line of rotating shaft VI and rotating shaft II, and according to the dead point principle, press frame can not fall down under external force, reduces potential safety hazard.(3) mounting means is simple, and is easy to operate.(4) labour intensity is little, the safety factor height.
(4) description of drawings:
Fig. 1 is the structural representation of the related a kind of press frame uplifting device of the present invention.
Fig. 2 lifts the structural representation of state for the press frame in the related a kind of press frame uplifting device of the present invention.
Wherein: 1 is press frame, and 2 is fork, and 2-1 is fixed leg hook groove, and 3 is connecting rod, and 4 is curved rod, and 4-1 is groove, 5 is pillar stiffener, and 6 is cylinder, and 7 is fixed leg, and 8 are defeated paper platform, and 9 are the rotating shaft I, 10 are the rotating shaft II, and 11 are the rotating shaft III, and 12 are the rotating shaft IV, and 13 are the rotating shaft V, and 14 are the rotating shaft VI.
