Description
Technical field
The utility model relates to a kind of mechanical pick-up device product manufacturing technology field, especially refers to the induction feedback device of sensor.
Background technology
At present, in the known pulp technology for making paper, generally be by felt transmission l Water Paper, squeeze and slough the moisture in the l Water Paper, thereby make smooth, smooth former paper product.But, because felt is to do to circle round at a high speed transmission around many deflector rolls, therefore a plurality of sensors need be installed at the edge of felt, with the position, the left and right sides of timely adjustment felt, avoid producing waste product.Traditional felt deflection correction sensor great majority are substituted by common travel switch, by after the adjusting device, deflector roll finely tuned again, thus the steady transmission that keeps felt.But traditional travel switch belongs to simple electrical category product, and its sensitivity, reliability are subject to the influence of the paper waste of paper-making process generation, thereby influence operate as normal.For this reason, people expect to invent a kind of need not power supply and feedback transmission very easily the deflection correction sensor product come out, required to satisfy in the adverse circumstances of wet type papermaking operate as normal.
The utility model content
The technical problems to be solved in the utility model is to overcome defective and the deficiency that existing felt deflection correction sensor product is subject to paper waste influence and transmission of feedback information inconvenience, provides a kind of deflection correction sensor product that need not power supply and can satisfy operate as normal in the adverse circumstances of wet type papermaking to society.
The technical scheme that its technical problem that solves the utility model adopts is: the felt deflection correction sensor comprises the casing and the supporting with it case lid of sealing, is provided with pneumatic valve body in the casing, and the valve body middle part is provided with horizontal air flue; Described air flue is provided with air admission hole T, and this air admission hole T connects the intake interface of being located at the case lid surface by the air flue of valve inner; The left and right sides port of transverse air channel is provided with left and right sides spool, offers left and right air chamber respectively corresponding to the valve body of left and right sides spool thimble, and left and right air chamber offers left and right sides steam vent respectively; Two outsides of described left and right sides spool are outstanding to be connected to swinging mounting, and the outstanding place of connecing in swinging mounting two outsides is provided with damping spring; Sensor bar is screwed on the swing arm by screw rod, and the swing arm afterbody is connected in swinging mounting.
Be provided with fixed head in the described casing and be connected support; The sensor bar afterbody is provided with helmet; Connect the support lower end and be provided with the control screw; Left and right sides spool is embedded with sealing ring respectively at the correspondence position that is positioned at body cavity.
The utility model felt deflection correction sensor product, by lever principle, the skew of felt is acted on the left and right sides spool of being located in the valve body, open the high-pressure air source air flue by left and right sides spool, behind high-pressure air pipe, act on the cylinder of regulating felt deflector roll position, to reach deviation-correcting function.This product and existing known comparing, the utilization gases at high pressure are regulated the skew of deflector roll, have advantage easy to connect, as not to be subject to the paper waste erosion.This product need not power work, and simple in structure, easy for installation, good reliability can be widely used in the felt correction in the wet type paper-making process.
Description of drawings
Fig. 1 is the utility model product structure schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model comprises the casing 8 and the supporting with it case lid 7 of sealing, is provided with valve body 23 in the casing 8, and valve body 23 middle parts are provided with horizontal air flue; Described air flue middle part is provided with air admission hole T, connects the intake interface 21 of being located at case lid 7 surfaces through valve body 23 inner air flues, and is connected with compressed gas source by high-pressure air pipe.The left and right sides port of transverse air channel is provided with left and right sides spool 15,26, offers left air chamber A, right air chamber B respectively corresponding to the valve body 23 of the thimble position of left and right sides spool 15,26, and left air chamber A, right air chamber B offer left and right sides steam vent 19,24 respectively.Left and right sides steam vent 19,24 runs through the left and right exhaust port 20,22 of being located at case lid 7 surfaces by the air flue of valve body 23 inner chambers respectively.The outstanding outstanding place of connecing that is connected to swinging mounting 14, two outsides, two outsides of described left and right sides spool 15,26 is provided with damping spring 16,27 and adjustment screw 17,28.Sensor bar 1 of the present utility model is screwed on the swing arm 5 by screw rod 3, by rotational positioning nut 4, can regulate sensor bar 1 height.In order to prevent that the felt edge from touching screw rod 3, sensor bar 1 afterbody is provided with helmet 2.Described swing arm 5 is articulated in case lid 7 muscle ribs by pin 6, and swing arm 5 afterbodys are connected in the extension rod 10 of adjustment screw 28 through a spring 9.Smooth and easy in order to guarantee that adjustment screw 28 extension rods 10 swing, be provided with fixed head 11 in the casing 8 and be connected support 13.Connect support 13 lower ends and be provided with control screw 12, damage valve body 23 to prevent that spool 15,26 amplitudes of oscillation in the left and right sides are excessive.For preventing the leakage of gases at high pressure, left and right sides spool 15,26 is embedded with sealing ring 18,25 respectively at the correspondence position that is positioned at valve body 23 inner chambers.
