Description

Technical Field

[0001] This utility model relates to the field of PE bag processing technology, specifically to a finished product dividing device for PE bag processing. Background Technology

[0002] As is generally known, PE bags are transparent plastic bags widely used in the manufacture of packaging for clothing, bags, electronic products, etc. They can be mainly divided into PE flat bags, self-sealing bags, zipper bags, envelope bags, perforated tote bags, handle bags, and zipper bags.

[0003] Utility model patent with publication number "CN219859693U" discloses a finished product cutting device for PE bag processing, including a base, a first limiting bracket, a second limiting bracket, a fixed frame, a cutting device, and a collecting device. The first and second limiting brackets are located at one end of the upper surface of the base, which tighten the PE bags to be cut. The fixed frame is located at the other end of the upper surface of the base, and the cutting device is mounted on the fixed frame. Two connecting plates are located at one end of the base near the fixed frame, and the collecting device is mounted on the two connecting plates. The first and second limiting brackets facilitate adjustment of the tension of the PE bags being cut during movement, keeping the PE bags flat. The fixed frame and cutting device tighten the PE bags while cutting them quickly, improving the overall product quality. The collecting device facilitates the collection of the cut PE bags, improving production efficiency.

[0004] The device has shortcomings in its use. Although it can effectively collect the cut PE bags, it only fixes the PE bags during cutting and cannot guarantee that the PE bags are wrinkle-free. Wrinkles will cause uneven cutting surfaces, making the cut PE bags unusable and affecting product quality. Moreover, after cutting, the PE bags need to be put back on the collection device, and it cannot automatically roll up the PE bags. Therefore, we propose a finished product cutting device for PE bag processing. Utility Model Content

[0026] 1. The finished product dividing device for PE bag processing uses a first rotating rod, a moving block, a second rotating rod, and a flattening block to cooperate so that the flattening block falls together with the cutter. The flattening block first abuts against the bottom of the PE bag and flattens it, and then the cutter falls to divide the PE bag. The PE bag remains flat during the division, which can ensure the accuracy of the division and improve the qualified product rate.

[0027] 2. This PE bag processing finished product dividing device uses a circular tube that, during its movement, contacts the side of the glue tank near the fixed frame, pushing a one-way valve. This allows the glue inside the arc-shaped groove to flow out through the one-way valve and contact the outer circumference of the circular tube. After the circular tube is removed, the one-way valve automatically closes to prevent further glue leakage. The glue on the outer circumference of the circular tube allows the divided PE bags located on one side of the fixed frame to be glued together. As the circular tube rotates, the PE bags rotate with it and are wound up, eliminating the need for manual winding and winding, thus improving production efficiency and reducing labor costs.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 3 A finished product dividing device for PE bag processing includes a base 1, a fixed frame 2 mounted on the top of the base 1, a first cylinder 3 mounted on the top of the fixed frame 2, a telescopic rod 15 mounted on the output end of the first cylinder 3, the telescopic rod 15 being located inside the fixed frame 2, and a cutter 5 mounted on the bottom of the telescopic rod 15; the first cylinder 3 can drive the telescopic rod 15 to move up and down inside the fixed frame 2, and can drive the cutter 5 at the bottom of the telescopic rod 15 to move synchronously to divide the PE bag;

[0038] A movable block 17 is hinged to the inner top surface of the fixed frame 2, and a second rotating rod 18 is hinged to the bottom end of the movable block 17. The movable block 17 and the second rotating rod 18 are respectively provided on both sides of the telescopic rod 15. The movable block 17 and the second rotating rod 18 are located on both sides of the telescopic rod 15. The movable block 17 can rotate on the inner top surface of the fixed frame 2, and the movable block 17 can also rotate on the outside of the second rotating rod 18.

[0039] A flattening block 19 is installed at one end of the second rotating rod 18 near the telescopic rod 15. The bottom of the flattening block 19 is lower than the bottom of the cutter 5. Before the cutter 5 falls, the flattening block 19 contacts the PE bag to flatten it. The flattening block 19 is connected to the second rotating rod 18 and can move synchronously with the second rotating rod 18. When the telescopic rod 15 moves down, the moving block 17 cooperates with the first rotating rod 16 to control the second rotating rod 18 and the flattening block 19 to move away from the telescopic rod 15. Since the bottom of the flattening block 19 is lower than the bottom of the cutter 5, the two flattening blocks 19 flatten the PE bag to be cut first, and then the cutter 5 contacts the PE bag. At this time, the flattening block 19 can continue to move away from the telescopic rod 15.

[0040] The telescopic rod 15 is hinged at the center with a plurality of first rotating rods 16, one end of which is hinged to the top of the flattening block 19; the first rotating rod 16 can cooperate with the moving block 17 to control the trajectory of the second rotating rod 18 and the flattening block 19.

[0041] A dividing plate 4 is installed on the inner wall of the fixed frame 2. The dividing plate 4 is located directly below the telescopic rod 15. The dividing plate 4 can provide a plane for the PE bag to be divided. When the flattening block 19 flattens the PE bag, the PE bag can be tightly attached to the surface of the dividing plate 4, so that the PE bag remains horizontal and wrinkle-free.

[0042] A rotating square rod 14 is rotatably connected to the outer center of the dividing plate 4. Rotatable round tubes 10 are installed at both ends of the rotating square rod 14. The rotating square rod 14 can rotate around the central axis of the dividing plate 4 to move the position of the round tubes 10. The round tubes 10 can rotate at both ends of the rotating square rod 14 to wind up the PE bag.

[0043] A glue tank 9 is installed on the inner wall of the fixed frame 2. The glue tank 9 is located below the round tube 10. A square opening for glue to flow out is opened on the side of the glue tank 9 near the center of the fixed frame 2. The round tube 10 can contact the square opening. When the square rod 14 rotates to drive the round tube 10 to rotate, the telescopic rod 15 is at the top. When the round tube 10 after being wound up rotates from the left side of the dividing plate 4, passes above the dividing plate 4, and rotates to the right side of the dividing plate 4, the round tube 10 does not contact the cutter 5 and the flattening block 19. The round tube 10 located on the right side of the dividing plate 4 passes below the dividing plate 4 and contacts the side of the glue tank 9 near the center of the fixed frame 2. The glue can contact the outer circumference of the round tube 10 and remain on the outer circumference of the round tube 10. It rotates with the round tube 10 to the left side of the dividing plate 4, which can adhere the PE bag located to the left of the cutter 5 after division, so that the PE bag can be wound up with the rotation of the round tube 10.

[0044] Please see Figures 1 to 6A first motor 6 is installed on the outer wall of the fixed frame 2, and a connecting rod 7 is installed on the output shaft of the first motor 6. The connecting rod 7 passes through the fixed frame 2; the first motor 6 can drive the connecting rod 7 passing through the fixed frame 2 to rotate.

[0045] One end of the rotating square rod 14 is rotatably connected to a rotating round rod 8. A round tube 10 is sleeved on the outer circumference of the rotating round rod 8. The rotating round rod 8 passes through the round tube 10 and is located on both sides of the dividing plate 4. The rotating round rod 8 can rotate on the rotating square rod 14. The round tube 10 is installed on the rotating round rod 8 and can rotate synchronously with the rotating round rod 8. Both ends of the rotating round rod 8 are located outside the round tube 10 and are located on both sides of the dividing plate 4. During the dividing process, the cutter 5 can cooperate with the round tube 10 to divide the PE bag.

[0046] The connecting rod 7 can be connected to the rotating round rod 8. The end of the connecting rod 7 near the rotating round rod 8 is provided with a protrusion. The interior of the connecting rod 7 is provided with an electric drive device that can drive the protrusion to slide between the interior and exterior of the connecting rod 7. The end of the rotating round rod 8 near the connecting rod 7 is provided with a groove, the size of which is adapted to the size of the electric protrusion. When winding is required, the second cylinder controls the protrusion to move outward towards the end of the connecting rod 7 near the rotating round rod 8, abutting against the groove at the end of the rotating round rod 8 near the connecting rod 7. The first motor 6 drives the rotating round rod 8 to rotate. After winding is completed, the second cylinder controls the protrusion to slide inward towards the connecting rod 7, disengaging from the rotating round rod 8.

[0047] Please see Figures 1 to 5 A second motor 13 is installed on the inner wall of the fixed frame 2, and the output shaft of the second motor 13 is installed on the rotating square rod 14; the rotating square rod 14 can be driven to rotate around the center of the dividing plate 4 by the second motor 13.

[0048] A rotating shaft 20 is installed at the center of the rotating square rod 14, and the rotating shaft 20 is rotatably connected to the center of the dividing plate 4; the rotating shaft 20 and the second motor 13 can support the rotating square rod 14, and the second motor 13 can drive the rotating shaft 20 to rotate synchronously.

[0049] Please see Figures 1 to 4 and Figure 7 The glue tank 9 is triangular, and the side of the glue tank 9 near the center of the fixed frame 2 is an arc shape that gradually descends from the outside to the inside. The side of the glue tank 9 near the center of the fixed frame 2 is adapted to the movement trajectory of the round tube 10, so that when the round tube 10 rotates with the rotating square rod 14, the round tube 10 can maintain smooth contact with the side of the glue tank 9 near the center of the fixed frame 2.

[0050] Please see Figures 2 to 4 and Figure 7 The glue tank 9 has an arc-shaped groove 12 that can hold glue; the glue can flow out from the bottom of the arc-shaped groove 12.

[0051] The arc-shaped groove 12 is arc-shaped, gradually descending from the outside to the inside. The square opening is located at the bottom of the arc-shaped groove 12, and a one-way valve 11 that can completely seal the arc-shaped groove 12 is installed at the square opening. The arc-shaped groove 12 allows the glue to flow from the top of the arc-shaped groove 12 to the bottom of the arc-shaped groove 12 and out from the square opening. The one-way valve 11 can seal the arc-shaped groove 12 so that the glue remains in the arc-shaped groove 12.

[0052] Please see Figures 2 to 4 and Figure 7 The one-way valve 11 includes a valve cover and a torsion spring. The valve cover is connected to the top of the square opening via a shaft pin to open and close the square opening. The torsion spring is connected to the shaft pin to drive the valve cover to close the square opening. The round tube 10 can contact the valve cover and push the valve cover into the arc-shaped groove 12. When the round tube 10 rotates with the rotating square rod 14, the round tube 10 can push the one-way valve 11 into the arc-shaped groove 12, so that the glue flows out from the square opening and contacts the outer surface of the round tube 10 and remains on the outer surface of the round tube 10. After the round tube 10 continues to move upward, the torsion spring (not shown in the figure) can make the one-way valve 11 close the square opening, so that the glue stays in the arc-shaped groove 12.

[0053] Please see Figures 2 to 5 The telescopic rod 15 has square holes on both sides that pass through it, and the first rotating rod 16 is hinged to the inner wall of the square hole; the first rotating rod 16 can rotate within the square hole of the telescopic rod 15.

[0054] Please see Figures 2 to 4 The flattening block 19 is L-shaped and is located on both sides of the telescopic rod 15 and can contact the telescopic rod 15. The bottom of the L-shaped flattening block 19 can have more contact area with the PE bag, better flattening the PE bag to be cut. When the telescopic rod 15 is at the top, the first rotating rod 16 can drive the flattening block 19 to move towards the center of the telescopic rod 15 and contact the telescopic rod 15.

[0055] In summary, this finished product dividing device for PE bag processing, during use, connects rod 7 to the rotating round rod 8 on the left side of dividing plate 4, and rotates under the drive of the first motor 6, driving the round tube 10 to rotate together to wind up the PE bag. After winding up a suitable PE bag, connects rod 7 to rotating round rod 8, and starts the second motor 13, driving rotating square rod 14 to rotate around rotating shaft 20. The round tube 10 on the left side rotates from above the dividing plate 4 to the right side of the dividing plate 4. At this time, the first cylinder 3 starts, driving telescopic rod 15 to move downward. The first rotating rod 16 cooperates with moving block 17, second rotating rod 18 and flattening block 19, so that flattening block 19 first contacts the PE bag to flatten it, and then the cutter 5 contacts the PE bag to divide it. The round tube 10 and rotating round rod 8 on the right side can be removed and a new round tube 10 and rotating round rod 8 can be connected to the rotating square rod 14; when the rotating square rod 14 rotates around rotating shaft 20, the round tube 10 on the right side... The tube 10 rotates from below the dividing plate 4 to the left side of the dividing plate 4. The right-side round tube 10 contacts the side of the glue tank 9 near the center of the fixed frame 2 below the dividing plate 4, pushing the one-way valve 11 to move into the arc groove 12. At this time, the glue in the arc groove 12 will flow out from the square opening and contact the outer circumference of the round tube 10. At this time, the round tube 10 continues to move upward and does not contact the one-way valve 11. The one-way valve 11 can close the square opening under the action of the torsion spring (not shown in the figure) to prevent the glue from flowing out. The round tube 10 rotates to the left side of the dividing plate 4. At this time, the connecting rod 7 is connected to the rotating round rod 8 on the left side. The first motor 6 then works to drive the round tube 10 on the left side to rotate. The glue on the round tube 10 will stick the PE bag located on the left side of the cutter 5 after division to the outer surface of the round tube 10. The rotation of the round tube 10 can make the PE bag roll up to the outer surface of the round tube 10, so that the PE bag can be divided more accurately and can be automatically rolled up.
