Abstract

The utility model relates to a pressure regulator which is composed of a handwheel 1, a pressure regulating shaft 2, a screw nut 3, a first level worm screw supporting seat 4, a first level worm screw 5, a first level worm wheel 6, a camshaft 7, a second level worm screw 8, a second level eccentric worm wheel 9, a connecting rod 10, a second level worm screw supporting seat 11, a locking ring 12 and a locking screw nut 13, wherein the handwheel 1 rotates to drive the pressure regulating shaft 2. The first level worm screw 5 is driven to rotate, the first level worm wheel 6 rotates and the first level worm wheel 6 is fixedly connected with the second level worm screw 8. The second level eccentric worm wheel 9 is driven to rotate along the clockwise (anticlockwise) direction, so the vertical eccentricity e of an eccentric hole occurs or is increased or decreased to realize that the length L of the connecting rod 10 is slightly increased or slightly shortened. The distance of a movable and a still plates of a die cutting machine or a mark pressing machine or a gold blocking machine is changed, so the pressure between the movable and the still plates of the die cutting machine or the mark pressing machine or the gold blocking machine is regulated to reach the purpose of increasing or decreasing the pressure.

Description

Pressure regulator

Technical field

The utility model relates to a kind of pressure-regulating device that is used for flat-press flat-die cutting machine, marking press, gilding press.

Background technology

In the impression of printing packaging industry, die-cutting production, the pressure of requirement equipment working face keeps relative stability, to reach higher indentation die-cutting quality and production efficiency, but because the quantitative unequal factor of raw material (as paper), the operating pressure of equipment tends to the variation of generation or " owing " or " mistake ".Under-voltage then cross cutting tangent line is continuous, and impression is unintelligible, and is not full, and it is at random that the back paper is then cut in overvoltage, and inconvenience taking-up, and long-time overvoltage work damage mould and equipment easily.This just need adjust the operating pressure of equipment at any time according to the situation of change of operating pressure, makes it to keep " constant ".

Traditional pressure-regulating device; be eccentric gear, change the vertical degree of eccentricity e of its eccentric orfice, reach and change that length of connecting rod L realizes by pivot link one end; having regulated the back adopts a lock tooth plate that it is locked; prevent " resilience ", its shortcoming is that the pressure adjusting is coarse, and the amplitude of accommodation can only be the integral multiple of eccentric gear tooth pitch; can not be continuously, the accurate adjustment; the adjusting because the eccentric gear of each connecting rod can not link in addition occurs the phenomenon of connecting rod place pressure inequality easily, and must shut down pressure regulation.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of pressure regulator is provided.

It is the eccentric worm gear of secondary that the utility model changes traditional eccentric gear, change the vertical degree of eccentricity e of the eccentric worm gear eccentric orfice of connecting rod one end, reach and change length of connecting rod L, realize the adjustment of face pressure, the utility model has adopted the second-stage worm gear worm structure, realized accurate, the adjustment continuously of operating pressure, adjusted the back because the intrinsic self-locking performance of worm and gear has been realized easy to adjust, pressure stability.

See Fig. 1, pressure regulator, it is characterized in that: two second-stage worm bearings (11) connect by second-stage worm (8), second-stage worm bearing (11) is connected on the connecting rod (10) by bolt, has fixation, there is spiral to cooperate on the second-stage worm (8) with the eccentric worm gear of secondary (9), the vertical degree of eccentricity e of eccentric orfice of the eccentric worm gear of secondary (9), locking nut (13), locking nut (14) also plays the role of fastening at second-stage worm (8) one ends, the eccentric worm gear of secondary (9) is enclosed within the connecting rod (10), connecting rod (10) and camshaft (7) tight fit are seen Fig. 2, and one-level worm screw (5) cooperates with first-stage worm gear (6), see Fig. 3, first-stage worm gear (6) connects firmly with second-stage worm (8), sees Fig. 1, and above-mentioned all parts are formed the worm and gear parts, two groups of worm and gear parts are connected by pressure regulating axis (2), handwheel (1) also is connected and fixed by bolt and pressure regulating axis (2), sees Fig. 2, and the crank-pin (15) of cover is connected with the moving plate of die-cutting machine or marking press in the eccentric worm gear of secondary (9).

See Fig. 2, rotate second-stage worm (8) and can drive the eccentric worm gear of secondary (9) rotation that rotate the eccentric worm gear (9) of secondary, the vertical degree of eccentricity e of eccentric orfice is constantly variation just, causes connecting rod in the whole parts (10) length L to change, excursion is [e, e].The eccentric worm gear of secondary (9) is enclosed within the connecting rod (10), connecting rod (10) and camshaft (7) tight fit, and therefore, as long as the eccentric worm gear of secondary (9) rotates, connecting rod (10), camshaft (7) will move simultaneously.The crank-pin (15) of cover is connected with the moving plate of die-cutting machine or marking press in the eccentric worm gear of secondary (9), the variation of connecting rod (10) length L, make the variable in distance of the dynamic and static plate of die-cutting machine or marking press, thereby reach the purpose of pressure between the dynamic and static plate of regulating die-cutting machine or marking press.The utility model also can be installed in the operating pressure between gold stamping motor-driven plate of platen gilding press adjusted and the quiet plate.
