Technic data of semi automatic sealing machine for aerosol cans :
I. Function and Features
YX series semi-automatic aerosol can sealing machine has fully absorbed the advanced filling machine technology from the Swiss Pamasol Company, with high sealing speed, reliable sealing quality, as well as simple operation, adjustment and maintenance requirement. The machine is specially used for internal inflating sealing of global and universal 1-inch aerosol valve.
II. Basic Structure and Principle
Shown by the pneumatic principle in Diagram 1,semi-automatic aerosol can sealing machine is comprised by two groups of cylinders. The lower cylinder (compressing cylinder) drives the sealing head to press tightly the aerosol value to be sealed, while the upper cylinder is designed to complete the sealing operation. The working procedures are shown as follows: place the aerosol can to be sealed on the operation platform of the machine, step on the (inching) pedal value K1 to reverse the two-position, five-way and dual-air reversing valve V1, so that the upper chamber of the lower cylinder will inflows air. On this basis, the sealing head will go down to make the adjusting ring to press tightly the aerosol valve. By then, the concave surface of the piston rod of the lower cylinder will enter into the cylinder, giving out a signal to reverse the two-position, three-way, single-air reversing valve V2. As for this, the upper chamber of the upper cylinder will inlet air for sealing operation. After the sealing operation, the piston in the upper cylinder will push down the mechanical control stroke valve K2 to give out the signal to reverse the two-position, three-way, single-air reversing valve V1. Then, the lower chamber in the upper cylinder starts to inlet. After the piston of the sealing cylinder is restored, the lower cylinder will also be restored along the stroke. So far, a sealing procedure is completed, waiting for the next operation.
III. Installation, Debugging and Operation
- 1. Install the machine on flat and solid ground and adjust the screws at the feet of the operation platform to stabilize the operation platform on a horizontal level;
- 2. Connect the air supply to the binary jointer at the air source, turn on the pressure adjusting valve and adjust the working pressure at 0.45~0.7MPa.
- 3. Setup of sealing diameter: sealing diameter refers to the central diameter of the press market on the aerosol valve lid. Setup of this parameter is very important, for it will directly affect the air tightness of product, as well as the service life of end enclosure. A rough adjustment has been completed before delivery, so that users do not need to readjust. Hereby, this parameter only needs to be adjusted when the size of aerosol can is changed. When adjusting this parameter, press down the two locking pins (with springs installed internally) on top of the sealing body, rotate the central body to adjust the diameter. If rotating upwards, the size will increase, and if rotating downwards, the diameter will decrease. During each adjustment, the upper chamber of the sealing cylinder may inlet air. Use a caliper to measure the adjusted diameter of the sealing head (the pedal valve needs to be stepped on during measurement), until reaching to the standard. The sealing head diameter of this machine can be adjusted around Φ27.2～Φ27.6. Advanced factories may use a sealing diameter instrument to measure the sealing diameter of aerosol valve. The measured value should be better 27.3±0.15.
- 4. Setup of sealing depth: sealing depth refers to the distance between center of the press mark and the upper end face on the aerosol valve lid. Before delivery, a rough adjustment has been completed, so that users do not need to readjust by themselves. Hereby, this parameter only needs to be adjusted when the size of aerosol can is changed. Before adjustment, press upwards the two locking pins (with springs installed internally) at the button of the sealing body and the rotate the adjust ring to modulate the sealing depth. If rotating upwards, the depth will increase, and if rotating downwards, the size will decrease. Accurate sealing depth can be measured with a depth scale, i.e. the distance from the base surface to the bottom end of the sealing head. Sealing depth of this machine can be adjusted to 5.7±0.15mm. Advanced factories may use a sealing depth measurement instrument to measure the sealing depth of aerosol valve. The measured value should be better 5.2±0.15.
- 5. Setup of sealing head height: firstly release the locking screws on the side of the slide holder, and then rotate the hand wheel to adjust the height of the slide holder. In accordance with the height and size of different aerosol canes, the aerosol cans should be able to move freely below the sealing head, to ensure that the pressing and sealing operation can be done efficiently. Normally, without the air supply, the bottom of the depth adjustment ring on the sealing head should be lower than the mouth of aerosol cans for 10~15mm. After the adjustment, fasten tightly the locking screws on the side of the slide holder.
- 6. Setup of aerosol can position: firstly, release the fastening screws of the two positioning block on the operation platform; adjust the position of the block to ensure the aerosol cans and the filling head are homocentric. Then, fasten the screw again.
- 7. Setup of running speed: tighten the one-way throttle valve on the side of the measurement device; slowly release the one-way throttle valve during the operating until the speed is appropriate and the running is stable; fasten the one-way throttle valve.
- 8. Check the above adjustment procedures and then start the sealing operation. Place the aerosol can between the two positioning blocks and being close to the positioning blocks; press down the (inching) pedal valve K1 to complete the sealing. During the adjustment process, if the air cylinder can not be restored to the initial position, we may use button K3 in front of the operation platform for reposition.
