And then the output shaft of the rotary cylinder 2 reciprocates and drives the driving gear 24 of the gear pair transmission mechanism to rotate and reciprocate, so as to drive the driven gear 10 to reciprocate, the driven gear 10 drives the main shaft 3 to reciprocate when rotating, the lower part of the main shaft 3, which extends into the swing arm adjusting chamber 102 of the main cavity 1, drives the swing arm 4, the floating ball pull rod 5 and the sealing floating ball 6 to transmit together, and finally, the sealing floating ball 6 is driven to reciprocate in the bushing 7 through the reciprocating rotation of the main shaft 3. The sealing floating ball 6 is driven to move left and right in the lining 7 through the pulling mechanism, so that the sealing contact and separation between the sealing floating ball 6 and the sealing gasket 8 are controlled, the outflow and closing of the glue outlet channel 103 glue are controlled, the operation is convenient, time and labor are saved, and the metering precision of the plunger pump can be improved.
When in use, the glue outlet connecting device 17 of the oil separating type leakage-proof valve is connected with the glue inlet of the plunger pump, and when the plunger pump needs to meter glue downwards: the controller controls the output shaft of the rotary cylinder 2 to rotate in the positive direction, the main shaft 3 rotates anticlockwise to drive the floating ball pull rod 5 of the pulling mechanism to move leftwards, and simultaneously, the sealing floating ball 6 is driven to be in sealing contact with the sealing gasket 8, so that the colloid is prevented from continuously flowing out of the colloid flow channel in the main cavity 1; the pump rod of plunger pump is when its gluey chamber upper portion downstream, it also can further be sealed 6 and sealed between 8 extrusion of packing to advance the colloid in the pipeline bush 7 of gluing to receive the extrusion, further prevent that the colloid from continuing to flow out from the colloid circulation passageway in the main cavity body 1, the colloid that makes the gluey chamber of plunger pump produces certain pressure, glue mouthful unidirectional extrusion along the plunger pump, thereby further improve the degree of accuracy and the accuracy that high viscosity colloid goes out to glue, whole glue in-process that advances effectively prevents to take place the condition of strong friction between high viscosity colloid and the device and take place, when improving the accuracy of the measurement of high viscosity colloid, still prolong device's whole life, ensure that whole glue process that advances lasts effectively, satisfy the actual production demand, application range is wide.
After the action of gluing is accomplished when the plunger pump, the pump rod rebound of plunger pump, 2 output shaft antiport of simultaneous control rotary cylinder, main shaft 3 clockwise rotation, the floater pull rod 5 that drives pulling mechanism moves right, drive simultaneously and seal separately between floater 6 and the sealed pad 8, the colloid continues to flow out from the colloid circulation passageway in the main cavity 1 and enters into the gluey intracavity of plunger pump, according to the volume that the cock stem rises and supply the isometric colloid, wait for glue down next step, realize the reciprocal play of intermittent type nature according to actual demand and glue, can satisfy the production demand of actual big mechanized batch, time saving and labor saving, show the work efficiency who uses the ration of high viscosity colloid to go out to glue that improves, applicable wide range.
In conclusion, the oil separating type leakage-proof valve has the advantages of simple and ingenious structure and low manufacturing cost, and when the oil separating type leakage-proof valve is used in combination with a plunger pump, the accuracy and the uniformity of the glue output quantity of each time can be ensured under the condition that the plunger pump works for a long time, meanwhile, the strong friction between the filling material in the high-viscosity glue at the sealing part and the main shaft 3 can be effectively avoided, the continuous and effective production can be ensured, the abrasion resistance is high, and the service life of the device is prolonged; the application scope is wide, is particularly suitable for the micro-metering dispensing of high-viscosity colloid, can realize the accuracy of effectively and accurately controlling the micro-dispensing of high viscosity, is convenient to operate, saves time and labor, and obviously improves the working efficiency of the dispensing machine.
