The top of the knife handle 12-3-3 is fixed on the swing connection seat 12-2, and the swing connection seat 12-2 is fixed on the film cutting knife swing driving structure 12-1. In specific implementation, the film cutting knife swing driving structure 12-1 is realized based on the swing driving structure of the CNC cutting knife in the prior art, such as the CNC cutting knife device of the signal ARB100-6-60Z20TS3 of Huichuan Robot, which can drive the structure of the fixed swing connection seat 12-2 to realize various angles of movement up and down, left and right, and front and back. The position of the blade of the knife body 12-3-1 relative to the diaphragm 3 is set according to the requirements of the material itself and is achieved through the existing functions of the CNC cutting knife. In this embodiment, because the bottom of the material is completely the diaphragm 3 and the top is the packaging box 2 and the bottle body 1, the blade position is set at the bottom of the bottle body 1 below the packaging box 2.

[0022] The waste film fixing structure includes: a fixing through hole 12-9 provided on the film cutting operation table 12-11, and a fixing suction cup 12-12 provided below the film cutting operation table 12-11. The fixing suction cup 12-12 and the fixing through hole 12-9 are located on the same vertical line.

[0023] After the material linear pushing structure 6 pushes the material along the material channel 10 to the film cutting operation table 12-11 of the film cutting structure 12 station, the material laser detector 12-8 at the diaphragm station detects that material is placed on the film cutting operation table 12-11, and the fixed suction cup 12-12 is started to suck the diaphragm 3 pressed against the bottom of the bottle body 1; the film cutting knife swing driving structure 12-1 is started to drive the knife body 12-3-1 to perform film cutting operation on the diaphragm 3 along the rectangular periphery of the packaging box 3; the diaphragm 3 is divided into two parts, and the top of the diaphragm 3 will continue to enter the subsequent process together with the packaging box 3, and the diaphragm waste cut off from the bottom of the diaphragm 3 is left on the film cutting operation table 12-11. In the present invention, the diaphragm waste cut off from the bottom of the diaphragm is fixed on the film cutting operation table 12-11 by the fixed suction cup 12-12, which is convenient for the subsequent waste recovery operation, and the separation operation of the cut diaphragm waste and other parts of the material is preliminarily realized.

[0024] like Figure 4 , Figure 5 As shown, Figure 4 for Figure 3A schematic diagram of the cross-sectional structure of the waste film grabbing structure along the intersection line when the two waste film clamps 12-4-2 are merged; the waste film grabbing structure 12-4 includes: a waste film clamp 12-4-2 connected to the waste film clamp cylinder 12-4-1, the claw tip of the waste film clamp 12-4-2 is set vertically downward, and the waste film clamp cylinder 12-4-1 is set on the swing connecting seat 12-2.

[0025] The waste film lifting structure includes: a lifting through hole 12-10 arranged on the film cutting operation table 12-11, and a lifting shaft 12-14 arranged below the film cutting operation table 12-11, and the lifting shaft 12-14 is connected to the sliding seat of the lifting cylinder 12-13; the diameter of the lifting shaft 12-14 is smaller than the diameter of the lifting through hole 12-10, and the lifting shaft 12-14 and the lifting through hole 12-10 are located on the same vertical line; the sliding seat of the lifting cylinder 12-13 moves in the vertical direction, driving the lifting shaft 12-4 to pass through the lifting through hole 12-10, and lifting the waste diaphragm placed on the film cutting operation table 12-11. During specific implementation, the number of lifting through holes 12-10 is set according to the size of the bottom area of ​​the material. The lifting through holes 12-10 are set on the central axis of the film cutting operating table 12-11, and the diaphragm waste is lifted from the central axis position of the bottom of the diaphragm waste to avoid the problem of the diaphragm waste sliding due to gravity because the lifting position is too biased, which is convenient for the waste film clamping claw 12-4-2 to clamp and avoid the problem of process operation failure.

[0026] The film cutting knife swing driving structure 12-1 drives the knife body 12-3-1 to rotate along the rectangular periphery of the packaging box 3 for one circle, and the film cutting operation is completed; the material linear pushing structure 6 pushes the bottle body 1, the packaging box 2, and the diaphragm 3 on the top of the packaging box 2 to the next station along the material channel 10; the film cutting knife swing driving structure 12-1 drives the waste film clamping claw 12-4-2 to the top of the central axis position of the film cutting operation table 12-11; the fixed suction cup 12-12 is reversely started to end the suction of the diaphragm waste; the lifting cylinder 12-13 is started, the lifting shaft 12-4 rises upward, passes through the lifting through hole 12-10, and after the diaphragm waste is lifted to the preset position, the lifting cylinder 12-13 stops; The film clamping jaw cylinder 12-4-1 starts, and the two waste film clamping jaws 12-4-2 separate; after the film cutting knife swing driving structure 12-1 drives the waste film clamping jaw 12-4-2 to descend to the height where the waste film is lifted up, the waste film clamping jaw cylinder 12-4-1 starts in the reverse direction, and the two waste film clamping jaws 12-4-2 merge, and after clamping the lifted waste film, the film cutting knife swing driving structure 12-1 drives the waste film clamping jaw 12-4-2 to rise; the film cutting knife swing driving structure 12-1 brings the waste film clamping jaw 12-4-2 and the clamped waste film to the top of the waste material box 14, and the waste film clamping jaw cylinder 12-4-1 starts, and the two waste film clamping jaws 12-4-2 separate, realizing the recycling of the waste film. Finally, the film cutting knife swing driving structure 12-1 drives the knife body 12-3-1 back to the preset position above the film cutting operating table 12-11, waiting for the next diaphragm operation.

[0027] like Figure 3 As shown, the film pressing structure includes a film pressing plate 12-7, and the strip-shaped film pressing plate 12-7 is horizontally arranged above the film cutting operating table 12-11; one end of the film pressing plate 12-7 is fixedly connected to the output shaft of the film pressing swing cylinder 12-15, and the other end of the film pressing plate 12-7 extends above the film cutting operating table 12-11 as a swinging end, and the distance between the fixed point of the swinging end and the side of the diaphragm operating table is greater than the distance between the side wall of the material and the side of the film cutting operating table 12-11, so that the film pressing plate 12-7 can push the material to move when it swings; the film pressing plate 12-7 is driven by the film pressing swing cylinder 12-15, and swings back and forth in a fan shape along the feeding direction of the material. During specific implementation, the distance between the bottom end surface of the end of the film pressing plate 12-7 extending above the film cutting operating table 12-11 and the top end surface of the film cutting operating table 12-11 is set to be equal to the thickness of the diaphragm 3, so that after the film pressing plate 12-7 pushes the material forward, the swinging end of the film pressing plate 12-7 can press the diaphragm waste sucked by the fixed suction cup 12-12; the film pressing swing cylinder 12-15 is arranged on the outside of the film cutting operating table 12-11, and the default position of the film pressing plate 12-7 is parallel to the side wall of the film cutting operating table 12-11 to avoid hindering the loading operation of the material linear pushing structure 6.

[0028] After the film cutting operation is completed, the material linear pushing structure 6 comes to the front of the film cutting operation table 12-11, and the film pressing swing cylinder 12-15 is started, driving the film pressing plate 12-7 to swing to the top of the film cutting operation table 12-11 with the fixed end as the axis. After that, it continues to swing in the same direction at an angle, and after the bottle body 1 and the packaging box 2 are pushed a small displacement in the direction of material feeding, the bottom end surface of the swing end of the film pressing plate 12-7 presses the diaphragm waste sucked by the fixed suction cup 12-12; then the material linear pushing structure 6 comes to the film cutting operating table 12-11 from above, and pushes the bottle body 1, the packaging box 2, and the diaphragm 3 on the top of the packaging box 2 to the next workstation along the material channel 10; through the setting of the film pressing structure, before the bottle body 1 and the packaging box 2 are withdrawn, a corner of the diaphragm waste is pressed to ensure that the material linear pushing structure 6 will not take away the diaphragm waste due to friction during the pushing process, thereby further improving the possibility of successful diaphragm waste recovery operation by the film cutting structure.

[0029] The film pressing material positioning structure includes a film pressing positioning plate 12-5, and the film pressing positioning plate 12-5 is arranged along the material feeding direction ( Figure 3 The film pressing positioning plate 12-5 is fixed above the film cutting operating table 12-11 in the direction indicated by the arrow on the film cutting operating table 12-11, and the film pressing positioning plate 12-5 is fixed to the output end of the film pressing positioning cylinder 12-6. The film pressing positioning plate 12-5 is driven by the film pressing positioning cylinder 12-6 and moves perpendicular to the material feeding direction.

[0030] After the material linear pushing structure 6 pushes the material along the material channel 10 to the work station of the film cutting structure 12, before the cutting knife structure 12-3 starts to diaphragm, the film pressing positioning cylinder 12-6 is started, driving the film pressing positioning plate 12-5 to move the material perpendicular to the material feeding direction until the side wall of the material is aligned with the upper end surface of the film cutting operating table 12-11 and the film pressing material positioning plate 12-16 on the opposite side of the film pressing positioning plate 12-5. The position of the material is set at a fixed position on the upper end surface of the film cutting operating table 12-11 by the film pressing positioning plate 12-5 and the film pressing material positioning plate 12-16, so that after the film cutting knife swing driving structure 12-1 is started, film cutting can be started at the preset position, further ensuring that the film cutting process can be completed accurately.

[0031] The inverted-U-shaped waste film protective cover 12-4-4 is connected to the piston end of the protective cover lifting cylinder 12-4-3, and the protective cover lifting cylinder 12-4-3 is fixedly connected to the swing connection seat 12-2; the waste film protective cover 12-4-4 is driven by the protective cover lifting cylinder 12-4-3 and moves vertically above the cutter structure 12-3. The preset position of the waste film protective cover 12-4-4 is away from the cutter body 12-3-1 in the cutter structure 12-3. After the film cutting operation of the cutter body 12-3-1 on the diaphragm 3 is completed, the protective cover lifting cylinder 12-4-3 is activated to lower the waste film protective cover 12-4-4 until the waste film protective cover 12-4-4 completely covers the cutter body 12-3-1. Since the diaphragm 3 is a soft structure, during the process of the waste film clamping jaw 12-4-2 clamping the diaphragm waste driven by the film cutting knife swing drive structure 12-1, the diaphragm waste may float onto the cutter body 12-3-1, be damaged and broken, and even fragments may fall on the film cutting operation table 12-11, causing subsequent film cutting operations to fail; in the present invention, during the process of recovering the diaphragm waste, the cutter body 12-3-1 is completely shielded inside the protective cover 12-4-4, avoiding the waste film for cutting from being broken again and ensuring that the film cutting process can be accurately completed.
