Abstract
The utility model relates to an automatic rectifying device with materials. The utility model is suitable for rectifying base materials such as paper, membranes, boards, strips, pieces, etc., in industries such as paper making, membrane molding, printing packing, production line conveyer belt, etc. The utility model is composed of a left air box body which is fixed on a valve body, a valve core end which is filled with a membrane, a membrane seat, and a membrane orderly, a micro pneumatic amplifier which is composed of an entirety which is formed by that the membrane, the membrane seat, and the membrane are covered with a form panel and a front supporting base which is arranged in a right air box body and is provided with a spring, and is put in a valve cover with the valve core, a back supporting base which is connected with the valve core into a whole, and a servo valve which is formed by that the valve cover with the spring is fixed on the valve body. A sensor is connected with the micro pneumatic amplifier through a signal pipe into a whole. The signal is sent into the micro pneumatic amplifier by the sensor, and the amplified signal is used for rectifying by that an oil cylinder is controlled by the servo valve. The utility model has the advantages of high precision for rectifying, high sensitivity, and high transmission speed.
Description
The utility model relates to a kind of automatic gas-liquid deviation correcting device, suitable especially papermaking plastic film, printing packaging, the coating compound, the making sheet foliation, in the industries such as textile printing and dyeing, conveyor line load-transfer device, in transport process,, the error that Tension Control and machinery are caused adjusts the band material automatic deviation rectifying device that correction is used for base materials such as paper, film, plate, band, sheets because being the boundary position variation.
Existing various thin material and reel material are in process of production because of there being wrap around error, because both sides are rolled up unevenly, straight, user often need cut uneven one and re-use, and causes very big waste.
The purpose of this utility model is to provide a kind of band material automatic deviation rectifying device, has the automatic deviation correction function, correction precision height, highly sensitive, and can improve transfer rate, range of use is wide.
The utility model is achieved in that band material automatic deviation rectifying device is fixed on the valve body by left air casing, put diaphragm, film seat and diaphragm successively at the spool end, compress mini pressure amplifier and the spool that template is fixed into the preceding bearing formation of band spring in whole and the right gas tank body and put into valve pocket, rear support and spool fuse, and the valve gap of band spring is fixed on and constitutes the servovalve composition on the valve body.Also have sensor, and sensor connects into integral body by signal pipe and mini pressure amplifier.
Fig. 1. structural representation of the present utility model.
Fig. 2. running condition figure of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Valve pocket (5) middle cavity is placed periphery corresponding oilhole, the threaded spool of an end (7), and in peripheral annular groove, be placed with seal ring (6), spacing at right-hand member with internal circlip.
Valve body (4) upper end has oil outlet A, B, lower end that fuel feed hole P and two fuel return hole O, O ' are arranged.With screw rear support (3) and spool (7) are linked into an integrated entity, spring (2) is screwed on the left side of valve body (4) together with valve gap (1) constitutes servovalve then.
Left air casing (14) is screwed on the right side of valve body (4), puts diaphragm (8), film seat (9) and diaphragm (8) on the right-hand member of spool (7) successively into ', compress lamina membranacea (10) and be fixed into the whole mini pressure amplifier that constitutes with nut.Left air casing (14) has a breather hole on the lower surface.
On one end face of right gas tank body (15) set screw (13) and a flow regulating valve (12) and a pore are arranged, 2 oil cylinder position control cocks (11) are arranged on the upper surface, communicate with left and right gas tank body (14), (15) respectively.One pore is arranged on the lower surface, preceding bearing (20) and spring (2) are housed in the middle cavity.With closing up behind spring (2) alignment spool (7) center, be connected with left air casing (14) with screw.
The set screw (13) of flow regulating valve (12) is by longitudinal travel control air flue openings of sizes, thus the control charge flow rate.
Sensor is little air pressure pneumatic transmitter (18), one end is that the centre has parallel open, on the upper and lower end face at place a cooresponding long waist shaped induction opening is arranged respectively in the middle of upper and lower two cavitys (19) of opening part, end is upper and lower two sockets (17) in addition, socket (17) connected upper and lower two cavitys (19) respectively communicates, become interference to connect, and be connected with two pores on the right gas tank body (15) by signal pipe (16) respectively.
During use, sensor (18), oil cylinder, servovalve can be installed on the needed position as required.
As shown in Figure 2, at this moment sensor (18) can be suspended in midair it with the axle on the support by the through hole on it, and on the edge of the substrate paper that opening on it is aimed at will carry or film or plate or band or sheet etc.
If put, the reel material normally moves then no signal output, if reel material boundary position tilts, then the induction opening on the sensor (18) just is subjected at times strong and at other times weak air-flow effect, and the signal air-flow is sent to mini pressure amplifier from socket (17) amplifies through diaphragm (8 '), if the pressure in the right gas tank body (15) is greater than left side spring (2), then promoting spool (7) by diaphragm (8 ') is moved to the left, then fluid flows out from the A oil outlet, remove to stir base material through oil cylinder work, oil flows out from oil cylinder and flows back to valve body (4) through the B hydraulic fluid port, and O ' gets back to fuel tank through return opening.If the pressure in the right gas tank body (15) is less than the right spring (2), then moving right then by spring (2) drive spool (7), fluid flows out from the B oil outlet, stir base material round about through oil cylinder work, oil flows out from oil cylinder and flows to valve body (4) through the A hydraulic fluid port, and the return opening O on it gets back to fuel tank.So continuous automatic circulation is finished automatic deviation correction.
The utility model is compared with prior art: because adopting little air pressure pneumatic transmitter simple in structure, make very Little deviation all can be delivered to mini pressure amplifier through sensor, carries out through the servo valve control oil cylinder after amplifying again Correction, the precision height of therefore rectifying a deviation, highly sensitive. Simultaneously also improved 3～5 times of transmission speeds, good stability, Working environment is not had specific (special) requirements, so the scope of application is wide, and result of use is good.
