[0024] The following combination Figures 1-12 The reverse curved spiral bale opener of the present invention is described.

[0025] like Figures 1-8 and Figure 12 As shown, in one embodiment, the reverse curved spiral bagging machine includes a frame 1 and a blanking frame 2 fixedly mounted on the bottom of the frame 1, and further includes: The rotating frame 4 has two ends that are rotatably mounted on the inner wall of the frame 1, and a plurality of the rotating frames are provided; The movable knives 3 are linearly arranged on the outside of the rotating frame 4, and the number of movable knives 3 is set to be multiple, and the inclined directions of the movable knives 3 on the outside of adjacent rotating frames 4 are opposite, and they are arranged in an arc shape; The fixed blade 22 is axially symmetrically fixedly mounted at both ends of the frame 1; The linear array of movable slots 41 is provided outside the rotating frame 4 and is located between two adjacent movable knives 3. A plurality of movable slots 41 are provided. The moving block 5 is slidably connected to the moving groove 41; The inner wall of the fixed ring 6 is fixedly connected to the top of the moving block 5; The notches 61 are provided in a circular array on the fixing ring 6, with a plurality of notches and a cover plate 21 provided on the top; The striker 7 is movably arranged on the top of the notch 61; The impact assembly 8 is disposed in the slot 61 and is used to drive the impact rod 7 to move back and forth vertically.

[0026] Specifically, the pancake-shaped compressed plastic bottles are placed into the frame 1 and stacked on top of the rotating frame 4. The number of rotating frames 4 is set to an even number. The rotating direction of the rotating frame 4 on the same side is opposite to that of the rotating frame 4 on the other side. Driven by a motor, the rotating frame 4 rotates in the opposite direction, which will drive the movable knife 3 to rotate in the opposite direction. The shape of the movable knife 3 is designed to be arc-shaped. Since the rotating directions of the movable knives 3 on both sides are opposite and arc-shaped, this reverse curved spiral design makes the pancake-shaped compressed plastic bottles bounce on it and accelerate the splitting. In this way, the movable knife 3 can be further used to disassemble the pancake-shaped plastic bottles. The compressed plastic bottles are driven by the movable knife 3 (because the rotating directions of the movable knives 3 on both sides are opposite) to move toward the two ends of the frame 1 and gather at the two ends of the frame 1. The pancake-shaped plastic bottles will abut against the fixed knives 22 fixedly installed at both ends of the frame 1. During the flipping process, it will collide with the fixed knife 22, which can further improve the disassembly efficiency of the cake-shaped plastic bottles. During the rotation of the rotating frame 4, the moving block 5 can be moved back and forth laterally along the moving groove 41. The moving block 5 will also rotate synchronously with the rotating frame 4 while moving. The movement of the moving block 5 will drive the fixed ring 6 to move back and forth laterally. During the movement and rotation of the fixed ring 6, the impact component 8 is used to drive the impact rod 7 to move back and forth vertically. The impact rod 7 moves up and down and impacts the cake-shaped plastic bottles. When the plastic bottles hit the impact rod 7, they will be subjected to an instantaneous impact force. This impact force can help break the adhesion between the plastic bottles and make them disperse faster. Secondly, after the adhesion between the plastic bottles decreases, the moving knife 3 can also disassemble the plastic bottles more easily. A receiving frame is placed at the bottom of the blanking frame 2 to assist in the disassembled plastic bottles.

[0027] See Figure 6-Figure 8 As shown, in this embodiment, the impact assembly 8 includes a rotating rod 81 rotatably mounted on the inner wall of the slot 61, a circular plate 82 is fixedly provided at one end of the rotating rod 81, a connecting rod 83 is fixedly provided at one end of the circular plate 82, a ball 84 is movably provided at one end of the connecting rod 83, a limit frame 85 is installed on the outer ball head of the ball 84, a vertical rod 86 is movably provided inside one end of the limit frame 85, the top of the vertical rod 86 movably passes through the cover plate 21 and the end is fixedly connected to the impact rod 7.

[0028] Specifically, when the fixed ring 6 rotates synchronously with the rotating frame 4 and the moving block 5, the rotating rod 81 is rotated. The rotation of the rotating rod 81 will drive the circular plate 82 to rotate. The rotation of the circular plate 82 drives the connecting rod 83 to rotate, thereby driving the ball 84 to swing in the limit frame 85. The ball 84 is movably connected to the ball head of the limit frame 85, and thus drives the limit frame 85 to swing back and forth up and down and left and right. The vertical rod 86 can move back and forth relative to the slot 61 and swing back and forth at the same time. The vertical rod 86 moves back and forth up and down and swings left and right, which will drive the impact rod 7 to swing left and right while moving back and forth up and down. The impact rod 7 moves back and forth up and down and hits the plastic bottles, thereby reducing the bonding force between the cake-shaped plastic bottles, making it easier to disassemble.

[0029] See Figure 4 、 Figure 7 and Figure 9 As shown, in this embodiment, a chassis 9 is rotatably provided on the top of the cover plate 21 , and a plurality of arc-shaped plates 10 are movably provided in a circular array on four sides of the chassis 9 , and a plurality of push rods 11 are provided on the outer sides of the arc-shaped plates 10 .

[0030] Specifically, the impact rod 7 moves back and forth up and down and rotates left and right while rotating the chassis 9. The rotation of the chassis 9 will drive multiple curved plates 10 to rotate synchronously. In this application, the number of curved plates 10 is set to three. The rotation of the curved plates 10 will drive the push rod 11 to rotate synchronously. During the rotation of the push rod 11, it will collide with the pancake-shaped plastic bottles inside the frame 1, thereby accelerating the disassembly of the plastic bottles.

[0031] See Figures 8-10 As shown, in this embodiment, two ends of the chassis 9 are axially symmetrically provided with card slots 91 , and two ends of the striker rod 7 are axially symmetrically provided with card rods 12 , which slide vertically along the card slots 91 .

[0032] Specifically, the vertical rod 86 moves back and forth up and down, which will drive the impact rod 7 and the card rod 12 to move back and forth up and down. The card rod 12 moves up and down relative to the card slot 91 opened on the chassis 9. While the vertical rod 86 moves up and down, it will also rotate back and forth left and right, which will drive the impact rod 7 to move up and down and rotate back and forth left and right, thereby causing the chassis 9 to rotate back and forth left and right, and the curved plate 10 also rotates back and forth left and right. The rotation of the top rod 11 is used to collide with the plastic bottles, thereby reducing the adhesion between the plastic bottles.

[0033] See Figure 9 As shown, in this embodiment, a plurality of positioning blocks 13 are provided in a circular array on the top of the chassis 9, a sliding groove 131 is opened on the positioning block 13, a connecting block 14 is slidably provided in the sliding groove 131, and one end of the connecting block 14 is fixedly connected to the inner wall of the arc plate 10.

[0034] Specifically, when the chassis 9 rotates back and forth, the positioning block 13 will be driven to rotate synchronously together, and the connecting block 14 can slide laterally relative to the sliding groove 131. The rotation of the positioning block 13 will drive the connecting block 14 and the curved plate 10 to rotate synchronously together. While rotating synchronously, the connecting block 14 will be moved back and forth laterally along the sliding groove 131. The movement of the connecting block 14 will drive the curved plate 10 to expand outward relative to the chassis 9 or shrink back to its initial state. For example, when the curved plate 10 in the contracted state penetrates into a gap in a pancake-shaped plastic bottle, and then the curved plate 10 expands outward in the rotating state, the disassembly effect of the plastic bottle can be further improved.

[0035] See Figure 9As shown, in this embodiment, a plurality of limit blocks 15 are provided in a linear array from top to bottom on the inner wall of the curved plate 10, a limit groove 151 is provided in the limit block 15, and a plurality of inclined blocks 16 are provided in a circular array on the outer wall of the impact rod 7. The number of the inclined blocks 16 in a single row is the same as the number of the limit blocks 15 provided on a single curved plate 10, and the inclined blocks 16 are slidably connected to the limit groove 151.

[0036] Specifically, when the striker 7 moves downward, it will drive the inclined block 16 to move downward relative to the limit groove 151, thereby driving the limit block 15 to move laterally in the direction away from the inclined block 16, and the curved plate 10 will drive the connecting block 14 to move relative to the sliding groove 131 in the direction away from the striker 7, that is, multiple curved plates 10 will expand outward relative to the chassis 9, and the curved plate 10 will drive the top rod 11 to move outward, which can improve the disassembly effect of the plastic bottle; similarly, when the striker 7 moves upward, it will drive the inclined block 16 to move upward relative to the limit groove 151, thereby driving the limit block 15 to move laterally in the direction close to the inclined block 16, and the curved plate 10 will drive the connecting block 14 to move relative to the sliding groove 131 in the direction close to the striker 7, that is, multiple curved plates 10 will shrink inward relative to the chassis 9, and the vertical rod 86 and the striker 7 will move up and down and back and forth, and the limit block 15 and the inclined block 16 will cooperate with each other to achieve the alternate expansion and contraction of the curved plate 10, thereby improving the disassembly efficiency.

[0037] See Figure 4 、 Figure 5 and Figure 11 As shown, in this embodiment, a fixed rod 17 is movably provided inside the rotating frame 4, one end of the fixed rod 17 is fixedly connected to the inner wall of the frame 1, and a linear array of curved grooves 171 with the same number as the moving grooves 41 is opened on the fixed rod 17. A positioning rod 18 is fixedly provided at the bottom of the moving block 5, and the positioning rod 18 slides and fits with the surface of the curved groove 171 at one end away from the moving block 5.

[0038] Specifically, the rotation of the rotating frame 4 will drive the moving block 5, the positioning rod 18, and the fixed ring 6 to rotate synchronously together, the fixed rod 17 remains stationary, and one end of the positioning rod 18 will slide along the surface of the curved groove 171 during the rotation process. The moving block 5 will drive the fixed ring 6 to move back and forth horizontally along the moving groove 41. During the movement of the fixed ring 6, the impact rod 7 will move up and down and hit the plastic bottle. The movement of the fixed ring 6 can drive the impact rod 7 to move, so that the impact rod 7 can hit the plastic bottles in a larger area, covering a wider range and having higher disassembly efficiency.

[0039] See Figure 7 and Figure 8 As shown, in this embodiment, a gear 19 is fixedly sleeved on the outer side of the rotating rod 81 .

[0040] Specifically, the rotating gear 19 drives the rotating rod 81 to rotate, thereby realizing the vertical rod 86 and the striker 7 to move back and forth up and down, and the striker 7 can strike the plastic bottle to improve the disassembly efficiency.

[0041] See Figure 4 and Figure 7 As shown, in this embodiment, the fixing ring 6 is provided with a transverse groove 62 on one side of the notch 61, and a rack 20 is movably provided in the transverse groove 62. The shape of the rack 20 is L-shaped, and one end of the rack 20 movably passes through the transverse groove 62 and the end is fixedly connected to the outer wall of the rotating frame 4. The rack 20 is engaged with the gear 19 for transmission.

[0042] Specifically, when the fixed ring 6 moves back and forth laterally relative to the rotating frame 4, the gear 19 moves therewith. During the movement of the gear 19, it will engage with the rack 20. The rack 20 moves relative to the transverse groove 62. The rotation of the gear 19 will drive the rotating rod 81 to rotate to realize the up and down reciprocating movement of the striker 7. In this step, the cooperation between the gear 19 and the rack 20 can realize the up and down reciprocating movement of the fixed ring 6 while also realizing the up and down reciprocating movement of the striker 7, thereby improving the disassembly efficiency.

[0043] See Figure 8 and Figure 11 As shown, in this embodiment, the striker rod 7 and the push rod 11 need to be made of a material with a relatively high hardness, and the moving block 5 needs to be made of a material with a smooth surface.

[0044] Specifically, the impact rod 7 and the push rod 11 both need to be made of materials with higher hardness, so as to avoid damage during the collision with the plastic bottle and increase the service life. The moving block 5 will also move back and forth laterally along the moving groove 41 during the rotation process. Using smooth materials can reduce the friction during the movement and reduce the wear of accessories.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
