Description

(54) DEVICE FOR FILLING A PROPELLANT AEROSOL VESSEL

A device for filling air poles of ash vessels is known, comprising a drive, a back stem with an injection needle at the end, and an extractor mechanism,

However, in the known device, the sequence of output of the rod and expanding levers from the engagement with the valve of the vessel is disturbed.

The aim of the invention is to increase the reliability of the device. This is achieved by the fact that the expanding mechanism consists of a sleeve, on the inner cylindrical collar of which the Swinging levers are freely installed, and a clamp. Two shoulders levers interact with the annular вые umbrellas of the stem tip.

FIG. 1 shows the proposed device, the cut; in fig. 2 - cut the bottom of the device, the working position.

The described device comprises a pneumatic. Double-acting cylinder, which includes cylinder 1, piston 2, top cover 3 with nozzle 4 and bottom cover 5 with nozzle 6j and hollow rod 7 with sh-8 for connection to the device, ocymecTi Sewing supply of propellant. At the bottom

its part has a thread that connects it with a cone-shaped tip 9, two annular protrusions 10 and 11 and an injection needle 12c from the center 13, on the rod watans endrajky; a mechanism consisting of 14 and an inner collar 15, two shoulders the levers 16, the springs 17, the nuts 18 and the latch 19 With the axle 20, The follower 21 j is spring-mounted telescopically mounted on the outer surface of the vt-Ki,

The device works as follows.

Aerosol vessel 23 with a valve 24 is installed on the base 25. Through the nozzle 4 serves compressed air into the upper cavity of the pneumatic cylinder. The piston 2 together with the rod 7 and the lever mechanism moves downwards. The safety device 21 installs the vessel 23 under the expanding levers. The lever mechanism is stirred down until the sleeve 14 reaches the protrusion of the bottom cover. The rod 7, compressing the spring, moves downwards and pushes the lower ends of the ribs 16, which deform the valve body 24. At the same time, the annular protrusion

10 lug inserts the retainer into the groove vtushsh. The injection needle moves downward and opens the valve 24. The propylene through the hollow stem through the central hole 13 enters the vessel 23, I

After filling the aerosol filling of the vessel with the required amount of propellant, the supply of compressed air to the upper cavity of the pneumatic cylinder is stopped and air is started to flow under the piston, the pistons rod ic and the tip move upwards, and the expandable arms remain in the lower position until the tip clears the lock out of the groove. The annular protrusion of the donkey, lift up, runs onto the protrusions of the upper arm of the levers and spreads them out. At the same time, the lower ends of the arms are connected and disengaged from.

vessel. Further lifting of the valve and the clamping mechanism occurs together
