The rotary valve piston-type pneumatic stroke pump solves the problems of poor measuring accuracy, complicated structure, high machining accuracy requirement, easy dead lock situation and poor reliability found in like products in prior art.
Description
Technical field
The utility model relates to the positive-displacement metering pump that is used to pack, in particular for the filling pump of thickness body packing.
Background technique
In the AUTOMATIC PACKING MACHINE of existing thickness body, the power of the general piston type stroke pump that adopts is carried and is chain and gear transmission.Above-mentioned piston type stroke pump exists power to carry upward complex structure, and it must be the shortcoming of carrying out under outage state that metering is regulated.Because the rotary valve type turns round continuously, the unlatching of material feeding mouth and discharge port also changes being connected, and causes that pressure constantly changes in the delivery pipe, and measuring accuracy is poor, thereby in operation, require the continuous rotation of to-and-fro motion in the form of piston and rotary valve to work good, bring difficulty to operation.In addition, aspect like product, pneumatic type stroke pump, complex structure in gas circuit control, the requirement on machining accuracy height, simultaneously rotary valve two ends output shaft does not have bearings, entirely by the support that cooperates with the inner chamber surface of contact of both sides sealing and rotary valve, thereby causes the Sealing rapid wear, rotary valve and pump head cavity face are easy to wear, rotary valve phenomenons such as " stuck " often appears, poor reliability, and what influence was packed finishes.
The model utility content
The purpose of this utility model provides a kind of rotary valve type piston type pneumatic dynamic stroke pump, and the utility model has solved poor, the complex structure of measuring accuracy that existing like product exists, and the requirement on machining accuracy height, is prone to problems such as stuck phenomenon, poor reliability.
Rotary valve type piston type pneumatic dynamic stroke pump of the present utility model drives cylinder, sensor, control valve, rotary valve driving cylinder and rotary valve by material feeding and forms; Control valve is installed in material feeding and drives on the cylinder, and control valve is communicated with in the cylinder body of rotary valve driving cylinder; Rotary valve drives cylinder and is installed in the side that material feeding drives cylinder, and rotary valve is installed in the end that material feeding drives cylinder, and rotary valve drives the axle of the driving plug connection rotary valve of cylinder; Sensor is installed in material feeding and drives cylinder interior.
Rotary valve type piston type pneumatic dynamic stroke pump of the present utility model; make the control gas circuit of pump simpler; the support of rotary valve, the location more reliable; the measuring accuracy height does not have " stuck " phenomenon, and motivational drive is a pressurized air; be independent of other system; simple in structure, but and metering adjusting canbe used on line, need not to shut down.
Above-mentioned purpose is realized by the following technical programs: rotary valve type piston type pneumatic dynamic stroke pump, comprise that material feeding drives cylinder, position transducer, control valve, pump head, rotary valve driven unit etc., after the motion of material feeding cylinder piston puts in place, touch sensor and make control air power steering rotary valve drive reversing motion, 90 ℃ of driven rotary valve rotations, wait material feeding process is finished, thereby in whole material feeding process, one of rotary valve opening and feed inlet and outlet always keep unimpeded state.From above technological scheme as seen, the material feeding piston must move to put in place and can touch sensor, thereby make control valve enter next working procedure, guaranteed the accuracy of motion, moreover the control that resets of control valve changes sensor control into, make whole control process by the control of material feeding system, guarantee the precision of measuring.In addition, rotary valve scene 2 axle head changes bearings into, dedicated sealing member is adopted in sealing, has guaranteed the flexibility of motion, eliminates " stuck " phenomenon, special-purpose sealing is only engaged in sealing function, no longer relevant with support function, thus the working condition of Sealing improved, better tightness, longer service life, so the reliability of entire pump improves, increase working life.

Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A sectional view;
Fig. 3 is Figure 1B-B sectional view.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1-Fig. 3, rotary valve type piston type pneumatic dynamic stroke pump drives cylinder 1, sensor 2, control valve 3, rotary valve driving cylinder 4 and rotary valve 5 by material feeding and forms; Control valve 3 is installed in material feeding and drives on the gas 1, and control valve 3 is communicated with in the cylinder body of rotary valve driving cylinder 4; Rotary valve drives cylinder 4 and is installed in the side that material feeding drives cylinder 1, and rotary valve 5 is installed in the end that material feeding drives cylinder 1, and rotary valve drives the axle 5-1 of the driving plug 4-1 connection rotary valve 5 of cylinder 4; Sensor 2 is installed in material feeding and drives cylinder 1 inside.
Described control valve 3 is made of standard electric magnet valve 3-1 and workpiece 3-2, and standard electric magnet valve 3-1 is installed in material feeding by workpiece 3-2 and drives on the cylinder 1.
The bearing 5-2 that is supported on a 5-1 two ends is installed on rotary valve 5 inwalls, and bearing 5-2 installed inside has sealing oil sealing 5-3.
The course of action of rotary valve type piston type pneumatic dynamic stroke pump is: after control valve 3 obtains control information, the rotary driving valve drives gas 4 and rearward moves, thereby rotary valve 5 is rotated counterclockwise 90 ℃, and at this moment, material feeding drives the piston advances forward (material feeding) in the cylinder 1, until touching front end sensors 4, control valve 3 resets, and the rotary driving valve turns clockwise 90 ℃, and material feeding gas 1 drives piston and sensor 4, break away from the control valve 3 control result that resets, wait for the arriving of next control signal.
The control that resets of control valve 3 is used in combination with self-made components by the standard electric magnet valve, changes its intrinsic control procedure, and rotary valve 5 scene 2 axle heads are set up bearing and guaranteed that rotary valve and pump housing inner chamber tube directly do not produce friction, eliminate " stuck " hidden danger.In addition, its Sealing is no longer born supporting effect, strengthens its life-span, and sealing effect is better.
