Example two

Referring to fig. 1-6, a method for extracting and valve unloading of residual liquid in a steel cylinder by adopting an automatic liquefied petroleum gas steel cylinder residual liquid extracting and valve unloading device comprises the following production process principle steps:

the liquefied petroleum gas steel cylinders needing to draw residual liquid and disassemble the valve are put into the inlet of the conveying device 1, and the conveying device 1 conveys a group of four steel cylinders to the working position of the turnover device 2; wherein, the opening of the handle on the steel bottle is opposite to the notch 356 of the clamp 354, so that the clamp 354 can smoothly enter the handle to clamp the valve.

The clamping mechanism 24 clamps and fixes the steel cylinder conveyed into the turning seat 21, and a worker connects a residual liquid extraction pipeline with a steel cylinder valve. The first telescopic actuator 241 stretches and pushes the rod 242, and the rod 242 abuts and fixes the steel cylinder and the baffle 25.

The turnover seat 21 turns 180 degrees to discharge residual liquid. The first driving device 23 rotates to drive the first rotating shaft 22 to rotate, so as to drive the turnover seat 21 to turn over.

After the residual liquid in the steel bottle is completely discharged, the turnover seat 21 rotates 180 degrees to restore to the original position, a pipeline for residual liquid extraction on the valve is removed, and the clamping mechanism 24 is opened.

The conveying device 1 is started, the steel cylinders continue to be conveyed to the valve detaching device 3 along the conveying device 1, after the photoelectric switch 51 senses that the first steel cylinder reaches a designated position, the blocking device 52 stretches out to limit the steel cylinders, and the three follow-up steel cylinders are aligned in sequence. The valves of the four cylinders are aligned with respect to the clamps 354 of the valve unloading mechanism 35, respectively.

The second driving device 322 is started to drive the second rotating shaft 321 to rotate, so as to drive the clamping rod 324 to clamp the bottle body. The clamping mechanism 32 clamps the body of the steel cylinder to prevent rotation, at this time, the notch 356 of the clamp 354 faces the opening of the upper end handle of the steel cylinder, the pushing device 34 pushes the sliding plate 33 to move to one side of the steel cylinder, the valve unloading mechanism 35 follows the sliding plate 33 to move to one side of the steel cylinder, when the sliding plate 33 moves to the position right above the steel cylinder, the clamp 354 enters the opening of the handle of the steel cylinder, and the notch 356 of the clamp 354 is clamped into the hexagonal screwing part of the valve.

The second motor speed reducer 351 of the valve unloading mechanism 35 is started, firstly, the slow repeated forward and reverse rotation is carried out for 30 degrees, and when the control system 5 detects that the current of the second motor speed reducer 351 exceeds a preset value, the notch 356 of the clamp 354 is completely clamped with the valve; then, the second motor reducer 351 rotates counterclockwise for a preset number of turns and then removes the valve.

The lifting mechanism 36 drives the clamp 354 upward and the removed valve follows the clamp 354 upward and above the cylinder because the notch 356 of the clamp 354 has a width less than the diameter of the handle on the valve.

The pushing device 34 is started again, the pushing device 34 pushes the sliding plate 33 to move to the inclined sliding groove 42 side, the valve unloading mechanism 35 moves to the inclined sliding groove 42 side along with the sliding plate 33, when the sliding plate 33 moves to the farthest point, the clamp 354 is blocked from tilting by the limiting rod 43 of the valve recycling device 4, the valve falls into the inclined sliding groove 42 along the notch 356 under the action of dead weight, and the valve slides into the valve conveying belt 41 to be collected through the inclined sliding groove 42, so that valve recycling is realized.

When the lifting mechanism 36 drives the clamp 354 to move upwards and the valve moves upwards along with the clamp 354 and is higher than the steel cylinder, the blocking device 52 is retracted, the conveying device 1 can be started, and the steel cylinder is conveyed to enter a next working procedure; thereafter, the pushing device 34 pulls the slide plate 33 back to the initial position, and the lifting mechanism 36 drives the lifting plate 361 to move downward, so that the clamp 354 naturally falls to the initial position under the gravity and waits for a batch of steel cylinders.
