DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 to Figure 5 The PE film roll changing and unloading device shown comprises an operating table 1 , the upper surface of which is fixedly connected to a vertical plate 12 , to which a round tube 14 is rotatably connected, and the end of the round tube 14 is connected to a round box 2 .

[0023] A driving assembly for driving the round tube 14 to rotate is arranged above the operating table 1, and the driving assembly includes a third motor 15, a first gear 16, and a second gear 17. The third motor 15 is fixedly connected to the vertical plate 12, the first gear 16 is fixedly connected to the driving shaft of the third motor 15, the second gear 17 is fixedly connected to the round tube 14, and the first gear 16 and the second gear 17 are meshed and connected. When working, the third motor 15 rotates to drive the first gear 16 to rotate, and since the first gear 16 and the second gear 17 are meshed and connected, the second gear 17 drives the round tube 14 to rotate.

[0024] A pump body 13 is fixedly connected to the vertical plate 12, and a round tube 14 is connected to the pump body 13 via a rotary joint, and the pump body 13 can be switched between suction and air supply.

[0025] A cylinder 3 is fixedly connected to the side of the round box 2 facing away from the round tube 14. There are multiple cylinders 3, and the multiple cylinders 3 are evenly distributed around the axis. A slide drum 4 is slidably arranged on the cylinder 3. In order to make the cylinder 3 and the slide drum 4 rotate synchronously, a slide groove 18 is opened on the inner wall of the slide drum 4. A slider 7 is arranged inside the slide groove 18. The slider 7 is fixedly connected to the cylinder 3, and the reel 6 is inserted into the slide drum 4. The reel 6 winds up the film.

[0026] Specifically, multiple slides 4 are all connected with reels 6. When one of the reels 6 is needed to roll up the film, the driving assembly adjusts the reel 6 to the winding position through the round tube 14, the round box 2, the cylinder 3 and the slide 4, and the slide 4 slides outward on the cylinder 3 without being interfered by other structures such as the slide 4, and the cylinder 3, the slide 4 and the reel 6 rotate synchronously to roll up the film.

[0027] When the reel 6 is wound, the driving assembly drives the round box 2 to continue to rotate through the round tube 14, so that the next reel 6 is adjusted to the winding position and continues to be wound, completing the rapid roll change and maintaining the continuity of the processing.

[0028] The reel 6 that has completed winding can be unloaded from the slide 4 without affecting the winding of another reel 6.

[0029] The utility model can quickly change rolls and unload materials by arranging multiple groups of cylinders 3, slide cylinders 4 and other structures on the round box 2, thereby maintaining the continuity of processing.

[0030] A first motor 8 is fixedly connected to one side of the round box 2 close to the round tube 14. The first motor 8 is provided in plurality, and the plurality of first motors 8 correspond to the plurality of cylinders 3 one by one, and the cylinders 3 are fixedly connected to the driving shafts corresponding to the first motors 8. When working, the first motor 8 rotates to drive the cylinder 3 to rotate, and with the cooperation of the slide 18 and the slider 7, the slide cylinder 4 rotates synchronously to realize the winding of the film.

[0031] In order to control the sliding of the slide cylinder 4 , an air groove 5 is opened inside the cylinder 3 , and the round box 2 is connected with the slide cylinder 4 through the air groove 5 , and a solenoid valve 20 is fixedly connected inside the air groove 5 .

[0032] When working, the pump body 13 is controlled to supply air, and the electromagnetic valve 20 corresponding to the air groove 5 is opened. The pump body 13 delivers gas to the inside of the slide 4 through the round tube 14, the round box 2 and the air groove 5, so that the slide 4 slides outward, and then the electromagnetic valve 20 is closed, so that the slide 4 remains in the extended state, which is convenient for winding the film;

[0033] The pump body 13 is controlled to perform a suction operation and the electromagnetic valve 20 inside the corresponding gas groove 5 is opened. The pump body 13 sucks the gas of the slide cylinder 4 through the round tube 14, the round box 2 and the gas groove 5, so that the slide cylinder 4 is recovered, and then the electromagnetic valve 20 is closed.

[0034] In order to improve the stability of winding, square openings 19 are provided on both sides of the slide 4. The inside of the square openings 19 is fixedly connected with an arc box 9, which is in an arc shape and matches the inner ring of the slide 4, so as not to affect the sliding of the slide 4. A sealing ring is provided between the slide 4 and the cylinder 3 to reduce wear and improve sealing. The arc box 9 is connected to the slide 4 through the air hole 11, and the air bag 10 is connected to the arc box 9.

[0035] During operation, when the slide 4 slides outward, the gas inside the slide 4 enters the arc box 9 through the air hole 11, causing the air bag 10 to expand and then adaptively abut against the inner wall of the reel 6, completing the positioning of the reel 6 and improving the winding stability;

[0036] Furthermore, the expansion range of the airbag 10 is limited and will not excessively squeeze the reel 6 . It is only necessary to prevent the reel 6 from rotating outside the slide 4 .

[0037] When the slide 4 is recovered, the gas inside the airbag 10 is sucked through the air hole 11, so that the airbag 10 shrinks and returns to its original position, making it easier for the reel 6 to be taken out.

[0038] The utility model can control the extension and contraction of the slide 4 by arranging structures such as the air groove 5, the arc box 9, the air bag 10 and the pump body 13, so as to facilitate the roll change and unloading, and can also complete the positioning of the roll 6 and improve the stability of the winding.
