Abstract
The utility model relates to an air pump dispensing rotary valve on a paper feeder of an offset printer, which belongs to a special valve for a paper feeder that can automatically eliminate paper wool and guarantee the paper-feed smooth in time. In view of the problems of the prior art, the structure and an air passage of the valve are improved, namely, a successor paper unloading passage that is composed of an air-blowing opening, an annular groove, a throttling hole, a vent hole in the axial direction, and an arc-shaped groove, etc. is added into the rotary valve. The utility model is widely suitable for monocolor offset printers, multicolor offset printers, and other printing mechanisms with suction nozzles. The utility model has the characteristics of easy implementation, good using effect, etc.
Description
The air pump that the utility model relates on its defeated paper of offset press distributes rotary valve, belongs to a kind of defeated paper special service valve with automatic eliminating paper soft flocks function, and it is widely used on the printing machinery of monochrome, multicolour offset press and other band suction nozzle.
Though it is simple in structure for existing defeated paper rotary valve, it is very high to the printed sheet quality requirement.What use in view of domestic many middle or small printing houses are a large amount of is paper such as quality is on the low side, the paper hair is more newsprint and newsprint, in actual mechanical process, after rotary valve was air-breathing: the paper hair just entered in suction nozzle and the sebific duct, when unloading paper, air enters, and the paper hair that is inhaled into enters spool to stopping up, and causes spool and valve body to kill, and therefore existing defeated paper rotary valve needs frequent regularly unpicking and washing; Existing in addition rotary valve is to rely on the connection atmosphere to impel suction nozzle to unload paper, because slow movement in running up, often produces and unloads the paper hysteresis, causes the paper feeding suction nozzle to drag the paper phenomenon, the less stable of its defeated paper.
The utility model is intended to overcome above-mentioned being inadequate, it is easy to propose a kind of enforcement, result of use splendid automatic row's paper hair rotary valve---it is based on prior art, its structure and gas circuit have been carried out the improvement of essence: will independently dry respectively originally passage and air intake passage, concern according to the regular hour, can connect in good time and dexterously, promptly on the air intake passage of former rotary valve, set up follow-up air blowing and unloaded the paper passage, guarantee that the paper hair is constantly blown down discharge automatically, it is more steady and accurately and timely that defeated paper unloads paper action.
Accompanying drawing 1: defeated paper is arranged the structural representation one of paper hair rotary valve automatically;
Accompanying drawing 2: defeated paper is arranged the structural representation two of paper hair rotary valve automatically;
Accompanying drawing 3: the A-A cut-away view of accompanying drawing 2.
Concrete structure of the present utility model and detailed content are described below in conjunction with the accompanying drawings:
Shown in accompanying drawing 1-3: this valve is made up of spool (1), valve body (2), bearing (3), end cap (4), interface (5), sebific duct (6), air volume regulating switch institutes such as (7).Its main points are: spool (1) left end is corresponding inflatable mouth (D
1) post surface, garden on have an annular groove (T
1), groove (T
1) in and have a throttle orifice (d
1), spool (1) right-hand member is corresponding air entry (D
2) post surface, garden on have an annular groove (T
2), groove (T
2) have deep-slotted chip breaker (T in addition on the left and right side position
4) and (T
3); Have an axial passage (d in the spool (1)
2) its a left end head and plug (8), wherein throttle orifice (d are housed
1), axial passage (d
2) and deep-slotted chip breaker (T
4) or arc (T
3) can be communicated with respectively.(T
6), (T
7), (T
10), (T
12), be deep-slotted chip breaker, (T
5), (T
8), (T
9), (T
11) be straight trough ((T wherein
7) and (T
8), (T
9) and (T
10), (T
5) and (T
6), (T
11) and (T
12) form paper respectively and blow the blowing of pine, presser feet, paper feeding suction nozzle and shaking of paper separation suction nozzle passage).
When defeated paper of offset press and rotary valve thereof entered duty, spool (1) was by rotation counterclockwise, as deep-slotted chip breaker (T
6) go to hole (d
3) and air volume regulating switch (7) connect the position time, the paper feeding suction nozzle is in suction condition, this moment, the connection of gas circuit was in proper order: total gas port ((D
2), annular groove (T
2), straight trough (T
5), deep-slotted chip breaker (T
6), hole (d
3), air volume regulating switch (7), interface, sebific duct, suction nozzle.When suction nozzle unloaded paper, compressed air entered in the air intake passage, the deep-slotted chip breaker (T on spool this moment (1)
4) go to and hole (d
3) and the position connected of air volume regulating switch (7) on, the order that compressed air flows into is: total inflatable mouth (D
1), cannelure (T
1), throttle orifice (d
1), axial passage (d
2), deep-slotted chip breaker (T
4), hole (d
3), air volume regulating switch (7), interface, sebific duct, suction nozzle.
The utility model is compared with prior art: this valve has adopted follow-up air blowing to unload the paper technology, can impel the paper soft flocks in the air intake passage automatically to be removed, thereby effectively avoid gas circuit to stop up and fault, alleviate widely labor strength, improved operating efficiency; Simultaneously also improved the promptness that suction nozzle unloads paper, made defeated paper more stable. It has significantly economic benefit and social benefit.
Claims (2)
1, a kind of defeated paper that is assemblied on the printing machine is arranged paper hair rotary valve automatically, it is made up of spool (1), valve body (2), bearing (3), end cap (4), interface (5), sebific duct (6), air volume regulating switch institutes such as (7), and it is characterized in that: spool (1) left end is corresponding inflatable mouth (D
