Problems solved by technology

Since the sealing is completed by two separate cylinders, the concentricity and verticality of the two cylinders cannot be guaranteed, the sealing diameter and depth parameters are unstable, the product quality is not high, the impact force is large, and the cylinder shaft is prone to bending deformation. , the sealing speed is slow, the sealing effect is not good, etc.

Embodiment Construction

[0027] A pneumatic filling head for aerosol valve sealing, the present invention is characterized in that a sealing cylinder 1, a buffer cylinder 2, a positioning pressure cylinder 3, and a vacuuming cylinder 4 are respectively arranged in the filling head from top to bottom There are four cylinders in total; the push claw mechanism is set at the lower part of the vacuum pumping cylinder 4; the air pressure of the four cylinders in the filling head is controlled by the air control valve, so that the cylinders move step by step, and gradually complete air cushioning, downward positioning, slow pressurization, A cycle of vacuuming the original solution to defoam, seal and seal, and resetting the filling head realizes the sealing of the valve on the top of the aerosol tank and the inner wall of the tank;

[0028] The sealing cylinder 1, the buffer cylinder 2, the positioning pressure cylinder 3 and the vacuum cylinder 4 are respectively equipped with quick-change joints connected ...

Abstract

The invention discloses a pneumatic encapsulating head applied for enclosing an aerosol valve. The encapsulating head is characterized in that a sealing cylinder (1), a buffer cylinder (2), a positioning pressure cylinder (3), and a vacuumizing cylinder (4) are arranged in the encapsulating head from top to bottom. A pushing pawl mechanism is arranged in the lower part of the vacuumizing cylinder (4). The air pressures in four cylinders in the encapsulating head are controlled by an air control valve so as to make the cylinders operate in steps to finish a complete circle including gas buffering, downward positioning, slow pressurizing, vacummizing to eliminate foams in a stock solution, opening sealing, and encapsulating head resetting, so as to seal the top valve and internal wall of an aerosol tank. The sealing effect is good, the operation speed is quick, and the requirements of high speed and high efficient aerosol production can be fulfilled by the provided pneumatic encapsulating head.

Description

technical field [0001] The invention relates to liquid filling machinery and equipment, and mainly relates to aerosol pressure filling and sealing equipment. Background technique [0002] Aerosol refers to the preparation made by putting medicine and suitable propellant in a pressure-resistant sealed container with a special valve system, and the contents are sprayed out in the form of mist by the pressure of the propellant during use. The aerosol is a pressure-packed product, and the internal pressure at a constant temperature of 55°C is 0.5MPa-1.0Mpa. [0003] The aerosol filling machine for the production of aerosol is a special pressure-encapsulating equipment specially used for the production of aerosol products. Due to the special reason of pressure in the aerosol product, the filling is divided into two steps: liquid filling and gas filling. The liquid filling machine pours a certain amount of liquid (medicine liquid) into the aerosol tank under normal temperature a...
