Abstract
The utility model provides a pressure maintaining device of a printing knife. The pressure maintaining device comprises a scraping printing knife, a knife rest, two oil cylinders, an oil valve seat, an oil storage seat and a pressure reducing valve. The knife rest is arranged on the scraping printing knife, and the two oil cylinders are arranged on the upper portion of the knife rest. Each oil cylinder comprises a cylinder body, a piston and a piston rod which can make reciprocating movement are arranged in each cylinder body, and an oil inlet and an oil outlet are formed in each cylinder body. The piston rod of each oil cylinder is connected with the knife rest, and the oil inlets and the oil outlets are both communicated with the oil valve seat. The oil valve seat is communicated with the oil storage seat, the oil storage seat is connected with an outside air source through a gas pipeline, and the pressure reducing valve is arranged on the gas pipeline. According to the pressure maintaining device of the printing knife, a closed oil circuit is formed by the pressure reducing valve, the oil storage seat, the oil cylinders, the oil valve seat and the like, a control air circuit is formed by an outside air source and the pressure reducing valve to control the knife rest, the stability of the knife rest is greatly improved, and thus the stability of the scraping printing knife is also improved.
Description
Technical field
The utility model belongs to printing equipment field, is specifically related to a kind of pressurizer that prints cutter.
Background technology
Printing machine is the machine of printing word and image.Modern printing machine generally by locing up, inking, impression, Shu Zhideng mechanism form.Its operation principle is: the writings and image that first will print is made forme, be contained on printing machine, then China ink is coated on to the place that has writings and image on forme by artificial or printing machine, be transferred to directly or indirectly again paper or other stocks (as textile, metallic plate, plastic cement, leather, plank, glass and pottery) upper, thereby copy the printed matter identical with forme.The invention of printing machine and development, have important function for human civilization and cultural propagation.
Printing machine, in printing process, has lifts phenomenon, has added after pressurizer, can effectively prevent the generation of phenomenon here, makes printed patterns reach optimum efficiency.But pressurizer in the past substantially all adopts cylinder to carry out pressurize, because gas circuit has gas leak phenomenon, make cylinder pressurize shakiness, final printing effect is bad.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of stability better to print the pressurizer of cutter.
The utility model is achieved by the following technical solution:
Print a pressurizer for cutter, comprise scrape printing cutter, knife rest, two oil cylinders, fuel tap seat, oil storage seat and pressure-reducing valves, knife rest is set on scrape printing cutter, the top of described knife rest is provided with two oil cylinders; Described oil cylinder comprises a cylinder body, is provided with reciprocating piston and piston rod in described cylinder body, is provided with oil-in and oil-out on cylinder body; The piston rod of described oil cylinder is connected with knife rest, and oil-in and oil-out are all communicated with fuel tap seat; Described fuel tap seat is communicated with oil storage seat, and described oil storage seat is connected with external air source by gas piping, on described gas piping, is provided with pressure-reducing valve.
Further setting of the present utility model is, on the gas piping that described external air source is communicated with oil storage seat, is also provided with air gauge.
Further setting of the present utility model is, described two oil cylinders are separately positioned on the left and right sides of knife rest.
The pressurizer of printing cutter described in the utility model is by composition one closing oil paths such as pressure-reducing valve, oil storage seat, oil cylinder and fuel tap seats, and external air source and pressure-reducing valve composition one control gas circuit, control knife rest, the stability of knife rest is promoted greatly, thereby also promoted the stability of scrape printing cutter.
Accompanying drawing explanation
Fig. 1 is the structure chart of the pressurizer of printing cutter described in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model provides a kind of pressurizer that prints cutter, comprises scrape printing cutter 1, knife rest 2, two oil cylinders 3, fuel tap seat 4, oil storage seat 5 and pressure-reducing valves 6, and knife rest 2 is set on scrape printing cutter 1, and the top of described knife rest 2 is provided with two oil cylinders 3; Described two oil cylinders 3 are separately positioned on the left and right sides of knife rest 2.Described oil cylinder 3 comprises a cylinder body, is provided with reciprocating piston and piston rod in described cylinder body, is provided with oil-in and oil-out on cylinder body; The piston rod of described oil cylinder 3 is connected with knife rest 2, and oil-in and oil-out are all communicated with fuel tap seat 4; Described fuel tap seat 4 is communicated with oil storage seat 5, and described oil storage seat 5 is connected with external air source by gas piping, is provided with pressure-reducing valve 6 on described gas piping.On the gas piping that described external air source is communicated with oil storage seat, be also provided with air gauge 7.
In the time that external air source is not ventilated, oil cylinder 3 cutter setting frames 2 only have very little active force, and knife rest 2 is swingable; In the time that external air source is ventilated, oil cylinder 3 cutter setting frames 2 apply active force, and knife rest 2 is compressed downwards, thereby can prevent the generation of lifts phenomenon, make printed patterns reach optimum efficiency.
It is apparent to one skilled in the art that the utility model can be changed into various ways, such change do not think depart from scope of the present utility model.All so apparent modifications of the technical staff to described field, within being included in the scope of this claim.
