The material is fed through the conveyor belt 4, and the feeding speed is controlled by the conveying motor 3. A light curtain electric eye 15 is provided above the conveyor belt 4, which can accurately sense the material position. The pushing method adopts the method of the push rod 8 to push the material and take the bag away from the bag placing platform 11, which greatly increases the safety factor of the equipment and reduces the required labor cost. At the same time, the bag opening method is also changed, and the original air nozzle blowing is changed to a vacuum suction cup 14 to suck the bag open, and the cylinder 13 is used to control the descent and rise of the vacuum suction cup 14, which increases the stability when opening the bag.

[0026] Implementation 2:

[0027] like Figure 3 and Figure 4 As shown, the left and right sides of the bag buckle 16 are provided with platform fixing rods 17, and two platform fixing rods 17 are provided. Furthermore, a rotating cylinder 18 is installed at the right end of the bag opening device 20, and a platform tension spring 19 is installed at the left end of the bag opening device 20. The bag opening support plate 12 is also changed from the original swing arm control to the control of two rotating cylinders 18, making the bag opening more accurate. The whole machine is equipped with an accurate control system, which can start and stop the equipment through the touch screen 9, and change the parameters of the conveyor belt 4 and the push motor 7. This solution realizes the full automation of the bag opening machine, with low labor cost, high safety factor in the operation process, fast bagging speed, accurate control, etc.

[0028] Working principle: When the fully automatic bag opening machine is in use, first Figure 1-Figure 4, use both hands to push the platform fixing rod 17 of the bag placing platform 11 downward to the set position, place the bag on the bag placing platform 11, use the bag buckle 16 to pass through the bag and the reserved hole of the machine, push the platform fixing rod 17 upward to return to the set position, and at the same time, the platform tension spring 19 will apply pressure to the bag upward to fix the bag, press the start button of the fully automatic bag opening machine, the conveyor belt 4 starts to operate, and delivers the material to the position of the push rod 8. At the same time, the bag opening mechanism also starts to operate, and the cylinder 13 controls the vacuum suction cup 14 to fall and suck the bag open. The bag opening support plates 12 on both sides are closed and pushed forward to the middle, and open at the predetermined position. The bag opening support plates 12 on both sides open the bag to the predetermined shape. At this time, limited by the size of the bag, the bag opening plates 12 on both sides will not open to the maximum width and will not touch the pneumatic detection switch and will remain fixed. When the light curtain electric eye 15 senses that the material has reached the pushing position, the conveyor belt 4 stops operating and the pushing motor 7 starts operating, driving the pushing rod 8 to push the material into the bag, and pull the bag away from the bag placing platform 11 and push it into the finished product frame. The bag opening plates 12 on both sides continue to open to the maximum value without bag restriction and touch the pneumatic detection switch, and then the bag opening plates 12 on both sides close and return to the starting state to complete the packaging. Then the pushing motor 7 is retracted, and the conveyor belt 4 and the bag opening mechanism start operating again, and the operation is cyclic.
