[0027] Example 2

[0028] On the basis of Example 1, the pressing assembly includes: two cylinders a2 arranged inside the upper cavity 12, the two cylinders a2 are respectively located on both sides of the box body 1, two cylinders b21 are arranged near the middle position inside the upper cavity 12, piston rods 22 are arranged inside the cylinders a2 and b21, and a partition plate 23 is arranged between the inner walls of the lower cavity 13, one side of the partition plate 23 is slidably connected to a connecting frame a24, and the other side of the partition plate 23 is slidably connected to a connecting frame b25, and the two ends of the top of the connecting frame a24 pass through the fixed plate 11 and are respectively connected to the The two cylinders a2 are connected at the bottom, and the two ends of the top of the connecting frame b25 pass through the fixed plate 11 and are respectively connected to the two cylinders b21. Servo motors 26 are respectively fixedly installed on both sides of the partition plate 23. The tops of the two servo motors 26 are driven and connected with threaded screws 27. The connecting frame a24 and the connecting frame b25 are respectively threadedly connected to the outside of the two threaded screws 27. Four straight-mouth grooves 28 for accommodating the movement of the piston rod 22 are opened on one side of the box body 1, and a pressing groove 29 used in conjunction with the four straight-mouth grooves 28 is opened on one side of the collection frame 15.

[0029] The automatically peeled packaging bags fall into the collection frame 15. Since the packaging bags are in a fluffy state, the collection frame 15 will overflow. At this time, the servo motor 26 on the left is started. After the servo motor 26 is started, it drives the threaded screw 27 to rotate. The threaded screw 27 rotates and screws with the connecting frame a24, thereby driving the connecting frame a24 to move upward. The connecting frame a24 drives the two cylinders a2 to move upward. When it moves to the highest point, the two cylinders a2 are started to push out the piston rod 22. The piston rod 22 is pushed out from the straight-mouth groove 28. Then the rotation direction of the servo motor 26 is switched, so that the connecting frame a24 drives the two cylinders a2 to move downward. The two piston rods 22 move downward along the straight-mouth groove 28, thereby entering the pressing groove 29, and continuing to move downward to press the stacked The packaging bags are compacted downwards, and when the two cylinders a2 move to the bottom, the servo motor 26 is turned off. As the packaging bags continue to fall into the collection frame 15, the packaging bags will continue to stack up and overflow. The servo motor 26 on the right is started again. According to the above principle, the two cylinders b21 move upwards to the top, and then the two cylinders b21 are started again to push out the piston rod 22. The servo motor 26 on the right switches the rotation direction again, so that the cylinder b21 moves downward, and the piston rod 22 compacts the stacked packaging bags again. After compaction, the two cylinders a2 are turned off to make the piston rod 22 retract, and then the servo motor 26 on the right is turned off. In the above manner, the two cylinders a2 and the two cylinders b21 are repeatedly cycled to compress the fluffy waste paper bags into a tight state.

[0030] Example 3

[0031] On the basis of Example 2, the limit assembly includes: two travel grooves 3 opened on the upper surface of the base 14, the two rollers 16 on the same side are respectively located inside the two travel grooves 3, two installation grooves 31 are respectively opened at the bottom of the two travel grooves 3, the distance between the two installation grooves 31 on the same side is equal to the distance between the two rollers 16 on the same side, cylinders c32 are respectively installed in the installation grooves 31, and the tops of the cylinders c32 are fixedly connected with blocks 33. The base 14 is arranged in a trapezoidal structure with inclined platforms 34 fixedly connected at opposite ends, and guide grooves 35 corresponding to the two travel grooves 3 are respectively opened on the upper surfaces of the two inclined platforms 34.

[0032] When the collecting frame 15 is indeed full, it is necessary to replace the empty collecting frame 15. At this time, the two cylinders c32 on the front side are closed, so that the cylinder c32 drives the top stopper 33 to retract into the installation groove 31, thereby releasing the restriction on the forward movement of the collecting frame 15. Then, the collecting frame 15 is pushed down from the base 14, and the roller 16 moves along the travel groove 3, and slides down along the slope when it moves to the inclined platform 34. Then, the two cylinders c32 on the front side are started. After the cylinder c32 is started, the stopper 33 is pushed out from the installation groove 31, and then the empty collecting frame 15 is taken out, and the two cylinders c32 on the rear side are closed, so that the two stoppers 33 on the rear side are retracted into the installation groove 31. , push the empty collecting frame 15 onto the inclined platform 34 at the rear, align the rollers 16 on both sides with the two guide grooves 35, and the collecting frame 15 moves upward along the slope of the inclined platform 34. The guide grooves 35 can accurately guide the rollers 16 into the two travel grooves 3, and then push the collecting frame 15 onto the base 14. The rollers 16 stop moving after rolling and touching the two blocks 33 ejected from the front, and then start the two cylinders c32 at the rear. After the cylinder c32 is started, the block 33 is ejected, thereby restricting the front and rear sides of the collecting frame 15 to prevent the collecting frame 15 from moving. At this time, the four straight grooves 28 are aligned with the four pressing grooves 29, which is conducive to the piston rod 22 pressing the material.
