Abstract

The invention discloses an ink fountain flip balancing device. According to the ink fountain flip balancing device, a supporting shaft is mounted in an internal hole of a wall plate, one end of the supporting shaft and an ink fountain body are fixed into one body through a flat key by using a set screw, the other end of the supporting shaft extends out of the outer side of the wall plate, torsion springs are mounted on the supporting shaft extending out of the outer side of the wall plate, one end of each torsion spring is hung into a hole of a retaining ring and is tightened through a set screw, and the other end of each torsion spring is hung on the wall plate; a built-in digging handle is mounted in the ink fountain body, and the torque of the torsion springs and the gravity torque of the ink fountain body should be balanced. The ink fountain flip balancing device has the advantages that the operation is simple, an ink fountain can stay at any position in a manner that only one person stands at any position of the ink fountain and easily lifts/presses the built-in digging handle, the operation is very laborsaving, easy and convenient, the ink fountain flip balancing device is mounted inside a protective hood of the wall plate, the occupied space is small, the structure is simple, the number of components and parts used is small, the production cost is low, and the like.

Description

Ink fountain upset bascule

Technical field:

The present invention relates to a kind of ink fountain upset bascule, be specially adapted to the ink fountain upset of large format offset press.

Background technology:

Offset press is in ink system, ink fountain is by ink fountain body 6, inking blade 5 and go out ink roller 7 and form, existing offset press ink fountain switching mechanism is to adopt bar linkage structure, as Fig. 1, shown in 2, by push-and-pull operating grip 2 drivening rods 1, the back shaft 3 of ink fountain body 6 in being arranged on wallboard 8 holes rotated, dish spring 4 is contained in connecting rod 1 hole and is fixed on the end face of axle, thereby realize to China ink and clean, for large format offset press, because ink fountain weight is larger, breadth is wider, must a set of linkage be installed respectively at the two ends of ink fountain body, when work, the upset of this winding machine ink fountain body of pushing simultaneously.Its shortcoming is: two approximately 1600mm of cover switching mechanism distance, one people cannot operate at all, must two people could overturn on printing machine both sides simultaneously, moreover this mechanism takes up room larger, be stretched over machine wheel hub outside, affect the outward appearance of machine, and complex structure, part is more, administrative loads is large, production cost is high.

Summary of the invention:

Task of the present invention be propose a kind of simple to operate, take up room little, the ink fountain upset bascule that cost is low.

Task of the present invention completes like this, ink fountain upset bascule, it is characterized in that: back shaft is arranged in the endoporus of wallboard, described back shaft one end and ink fountain body are fixed as one with holding screw by flat key, the other end stretches out wallboard outside, stretch out on the back shaft in wallboard outside torsion spring is installed, described torsion spring one end hangs over that in the hole of back-up ring, to pass through holding screw fastening, and its other end hangs on wallboard.On affiliated ink fountain body, built-in stingy hand is housed, the moment of torsion of described torsion spring should balance each other with the gravity torque of ink fountain body.

The present invention has following effect: simple to operate, only need a people to stand in the meaning position, position of ink fountain, easily carry, by built-in stingy hand, can make ink fountain rest on and protect arbitrarily position, operate very laborsaving lightly, this mechanism is arranged on wallboard passport the inside, take up room little, simple in structure, use the advantages such as parts are few, and production cost is low.

Brief description of the drawings:

Fig. 1 is prior art station positional structure schematic diagram; Fig. 2 is ink fountain overturn structure schematic diagram; Fig. 3 is structural representation of the present invention.

Drawing explanation: 1, connecting rod, 2, operating grip, 3, back shaft, 4, dish spring, 5, inking blade, 6, ink fountain body, 7, go out ink roller, 8, wallboard, 9, flat key, 10, torsion spring, 11, holding screw, 12, back-up ring.

Detailed description of the invention:

The technical program has been abandoned the connecting rod 1 of Fig. 1 prior art, the securing members such as operating grip 2 and dish spring 4, and the technical program utilizes the torsion spring power of torsion spring 10 to carry out the gravity torque of balance ink fountain body.As shown in Figure 3, back shaft 3 is arranged in the endoporus of wallboard 8, described back shaft one end and ink fountain body 6 are fixed as one by flat key 9 use holding screws 11, the other end stretches out wallboard 8 outsides, stretch out on the back shaft in wallboard outside torsion spring 10 is installed, described torsion spring one end hangs in the hole of back-up ring 8 fastening by holding screw 11, its other end hangs on wallboard 8, the moment of torsion of adjusting torsion spring 10 when assembling balances each other the gravity torque of itself and ink fountain body 6, can realize freely overturning of ink fountain body, for handled easily, on ink fountain body, add built-in stingy hand, by built-in stingy hand, can make ink fountain body stop optional position, operate very laborsaving and light.

Claims

1. ink fountain upset bascule, it is characterized in that: back shaft is arranged in the endoporus of wallboard, described back shaft one end and ink fountain body are fixed as one with holding screw by flat key, the other end stretches out wallboard outside, stretch out on the back shaft in wallboard outside torsion spring is installed, described torsion spring one end hangs in the hole of back-up ring fastening by holding screw, and its other end hangs on wallboard.

2. ink fountain upset bascule according to claim 1, is characterized in that: built-in stingy hand is housed on affiliated ink fountain body, and the moment of torsion of described torsion spring should balance each other with the gravity torque of ink fountain body.
