[0051] After the material is loaded, it is placed on the feeding platform 3, and the positioning structure includes: a positioning plate 10 arranged parallel to the length direction of the single-sided film cutting channel 5-1; the positioning plate 10 is arranged on the opposite side of the film cutting knife structure 6 on the single-sided film cutting channel 5-1; the positioning plate 10 is driven by the positioning cylinder 10-1 to push the material placed on the feeding platform 3 to the side where the film cutting knife structure 6 is arranged, so that the diaphragm 2 on the material is within the diaphragm range of the film cutting knife structure 6.

[0052] The single-sided film cutting channel 5-1 is connected to the feeding platform 3, and the feeding pushing structure includes a pushing plate 9 and a pushing driving structure (marked in the figure). The pushing driving structure includes: a pushing motor, a screw, and a screw pair. The screw of the feeding pushing structure is arranged parallel to the length direction of the single-sided film cutting channel 5-1, and the pushing plate 9 is arranged perpendicular to the length direction of the single-sided film cutting channel 5-1. The pushing groove 11 is arranged parallel to the length direction of the single-sided film cutting channel 5-1. The push plate 9 passes through the pushing groove 11 through a connecting piece below, and is connected to the screw and screw pair arranged at the bottom of the single-sided film cutting channel 5-1. The pushing motor drives the pushing plate 9 to push the material along the single-sided film cutting channel 5-1 in the horizontal direction. During the feeding process, the film cutting knife structure 6 on one side of the single-sided film cutting channel 5-1 performs hot-melt film operation on one side of the diaphragm 2.

[0053] The double-sided diaphragm pushing structure 12 is arranged at the entrance of the double-sided film cutting channel 5-2, the pushing direction is perpendicular to the single-sided film cutting channel 5-1, and the pushing stroke is arranged between the entrance of the double-sided film cutting channel 5-2 and the film clamping structure 7. In specific implementation, the double-sided diaphragm pushing structure 12 can be implemented based on a device capable of realizing linear drive in the prior art, such as a synchronous belt type, a ball screw type, a linear motor type module, or a cylinder; this embodiment is implemented based on the pushing cylinder 12-1, and the output rod of the pushing cylinder 12-1 is connected to the double-sided film cutting pushing plate 12-2; after the pushing cylinder 12-1 is started, the double-sided film cutting pushing plate 12-2 pushes the material placed in front to make a linear motion along the double-sided film cutting channel 5-2, and sends the cutting edge of the cut diaphragm 2 into between the prepared upper and lower clamping jaws of the film clamping structure 7.

[0054] The double-sided film cutting drive structure 14 is fixedly connected to the film cutting knife structures 6 on both sides of the double-sided film cutting channel 5-2, and the travel of the double-sided film cutting drive structure 14 includes the double-sided film cutting channel 5-2 between the film clamping structure 7 and the entrance of the double-sided film cutting channel 5-2. In this embodiment, the double-sided film cutting drive structure 14 is implemented based on a double-sided diaphragm linear module, and the slide of the double-sided film cutting linear module is fixedly connected to the film cutting knife structures 6 on both sides of the double-sided film cutting channel 5-2, driving the film cutting knife structures 6 on both sides to make linear motion along the double-sided film cutting channel 5-2; the default position of the two film cutting knife structures 6 driven by the double-sided film cutting drive structure 14 is set at one end of the film stripping structure 8 near the forward direction of the material in the double-sided film cutting channel 5-2.

[0055] After using the technical solution of the present invention, by respectively arranging a single-sided film cutting knife structure 6 and a double-sided film cutting knife structure 6 on the mutually perpendicular and connected single-sided film cutting channel 5-1 and double-sided film cutting channel 5-2, it is ensured that the three adjacent and mutually perpendicular sides of the diaphragm 2 on the material can contact the hot melt knife; by first cutting one side of the diaphragm 2 in the single-sided film cutting channel 5-1, and then the double-sided diaphragm pushing structure 12 pushes the material, with the direction of the cut side as the forward direction, into the double-sided film cutting channel 5-2, and after the film clamping structure 7 is lowered, the knife edge of the separated side film 2-3 is clamped out, and then the film clamping structure 7 is raised to tighten the cut side film 2 The cutting edge of the side film 2-3, the double-sided diaphragm pushing structure 12 drives the two film cutting knife structures 6 to move in the direction opposite to the material advancing direction, and the two film cutting knife structures 6 cut the side walls of the diaphragm 2 on the two adjacent sides of the separated side film 2-3; because the cutting edge of the single-sided film cutting knife structure 6 has been pulled open, after the height and horizontal position of the double-sided film cutting knife structure 6-1 are adjusted, it can be ensured that the cutting edge of the double-sided film cutting knife structure 6 is consistent with the cutting edge of the single-sided film cutting knife structure 6, thereby ensuring that the three side walls of the top film 2-1 of the diaphragm 2 are completely cut, ensuring the success rate of the subsequent film stripping operation on the film stripping structure 8.

[0056] like Figure 3 , Figure 4 As shown, the film cutting knife structure 6 includes: an arc-shaped blade 6-15 is set at one end of the film cutting knife 6-1, and the other end of the film cutting knife 6-1 is swingably mounted horizontally on a mounting plate 6-5 through a swinging structure, and the mounting plate 6-5 is fixed on the film cutting knife lifting structure, and the film cutting knife lifting structure is fixed on the film cutting knife horizontal adjustment structure; the length of the film cutting knife 6-1 and the curvature of the blade 6-15 are adjusted according to the size of the bottle body 1, ensuring that the film cutting knife structure 6 can be suitable for materials of various sizes, thereby ensuring that the present invention is more practical.

[0057] The swing structure includes: a flat copper sleeve 6-2 fixedly connected to the film cutting knife 6-1, and a positioning spring 6-3; the copper sleeve 6-2 is fixedly connected to one end of the positioning shaft 6-7, and the other end of the positioning shaft 6-7 is vertically inserted into the inner cavity of the positioning shaft seat 6-8, and the positioning shaft 6-7 and the positioning shaft seat 6-8 are clearance-matched, and a cover plate 6-11 is set on the top of the positioning shaft 6-7 for sealing to prevent impurities from entering the inner cavity of the positioning shaft seat 6-8.

[0058] The positioning shaft seat 6-8 is fixed on the mounting plate 6-5, and a spring fixing column 6-4 pointing vertically downward is arranged on the bottom surface of the copper sleeve 6-2 at the tail end of the film cutting knife 6-1, and the two ends of the horizontally arranged positioning spring 6-3 are respectively fixedly connected to the spring fixing column 6-4 and the mounting plate 6-5; the film cutting knife 6-1 is a hot melt knife, and the film cutting knife 6-1 is connected to a heating rod 6-6 fixedly installed on the copper sleeve 6-2, and a temperature sensor 6-10 is arranged on the bottom surface of the copper sleeve 6-2; the temperature of the hot melt knife is monitored in real time by the temperature sensor 6-10 to ensure that the film cutting knife 6-1 can reach the preset temperature. At the same time, the heating rod 6-6 and the temperature sensor 6-10 can ensure that the film cutting knife 6-1 can be adjusted to different temperatures according to the diaphragms 2 of different materials, thereby ensuring that the technical solution of the present invention is suitable for different production scenarios.

[0059] The heating rod 6-6 heats the film cutting knife 6-1 to a preset temperature. When the material is moving, the diaphragm 2 comes into contact with the blade 6-15 and is cut by hot melting. After the film cutting knife 6-1 cuts the diaphragm 2 and encounters the blocking force of the bottle body 1, the positioning shaft 6-7 rotates in the inner cavity of the positioning shaft seat 6-8, driving the film cutting knife 6-1 to rotate, ensuring that the film cutting knife 6-1 does not damage the bottle body 1; after the film cutting knife 6-1 passes through the bottle body, the positioning spring 6-3 pulls the spring fixing column 6-4 set at the tail end of the film cutting knife 6-1 to pull the film cutting knife 6-1 back to its original position, and hot-melt cuts the diaphragm 2 at the next bottle body 1; the swinging structure ensures that the film cutting knife 6-1 can continuously pass through the entire row of bottle bodies 1 in the diaphragm 2 without damaging the bottle body 1. The curved blade of the film cutting knife 6-1 can ensure that when the film cutting knife 6-1 first hot-melts the diaphragm 2, the cutting edge will appear on the diaphragm on the front side in the forward direction of the material, and after cutting the side wall of the diaphragm where the film cutting knife 6-1 is located, a cutting edge will also be produced on the side film at the tail of the material; further ensuring that the cutting edge produced by the single-sided film cutting knife 6-1 set on the single-sided film cutting channel 5-1 is consistent with the cutting edge produced by the double-sided film cutting knife 6-1 on the subsequent double-sided film cutting channel 5-2.

[0061] The film cutting knife horizontal adjustment structure includes a horizontally arranged film cutting knife horizontal adjustment slider 6-13, and the bottom end of the film cutting knife bracket 6-14 is connected to the film cutting knife horizontal adjustment slider 6-13 through a slider rail; a through hole with an inner spiral is provided on the film cutting knife bracket 6-14 perpendicular to the film cutting knife horizontal adjustment slider 6-13, and a horizontal tightening nut 6-17 with an adjustment handle passes through the hole and is tightened on the film cutting knife horizontal adjustment slider 6-13. When the horizontal position of the film cutting knife 6-1 needs to be adjusted, the horizontal tightening nut 6-17 is rotated to loosen the tightening force on the film cutting knife horizontal adjustment slider 6-13, and after the film cutting knife 6-1 is adjusted to the horizontal position along with the film cutting knife lifting structure, the horizontal tightening nut 6-17 is tightened to fix the horizontal position of the film cutting knife 6-1.

[0062] The film cutting knife lifting structure and the film cutting knife horizontal adjustment structure adjust the horizontal and vertical positions of the film cutting knife 6-1, so that the three film cutting knives 6-1 can be set at the same horizontal height, ensuring that the blades of the two diaphragms are consistent, and also ensuring that the technical solution of the present invention can be applied to materials of different sizes.

[0063] like Figure 5 , Figure 6 As shown, the film clamping structure 7 includes: a clamping jaw 7-1, a clamping jaw driving structure 7-9, a clamping jaw lifting structure 7-5, and a suspension structure 7-3; the clamping jaw 7-1 is driven by the clamping jaw driving structure 7-9 to complete the opening and closing action; the suspension structure 7-3 is fixed on the clamping jaw lifting structure 7-5, and the clamping jaw 7-1 and the clamping jaw driving structure 7-9 are installed on the suspension structure 7-3 through the clamping jaw seat 7-2, and the suspension structure 7-3 suspends the clamping jaw horizontally above the double-sided film cutting channel 5-2.

When the material and the clamp 7-1 continue to move relative to each other, the mounting end 7-1-102 of the lower clamp 7-1-1 extends into the separated cutting edge of the diaphragm 2, and the clamp cylinder moves in the opposite direction. The output shaft of the clamp cylinder pushes the mounting end 7-1-102 of the lower clamp 7-1-1 downward, and the clamp end 7-1-101 of the lower clamp 7-1-1 rotates upward, so that the clamp end 7-1-101 and the upper clamp 7-1-201 are closed, clamping the diaphragm 2 located in the device.

[0066] The shapes of the bottom end surface of the upper clamping jaw 7-1-201 and the top end surface of the clamping jaw end 7-1-101 are interlocking with each other; in this embodiment, the bottom end surface of the clamping jaw 7-1-201 and the top end surface of the clamping jaw end 7-1-101 are respectively provided with tooth-like structures with interlocking shapes, ensuring that the diaphragm 2 clamped therein can be locked, reducing the possibility of the diaphragm falling off during the process of tightening the diaphragm 2, and further improving the possibility of successful membrane cutting of the double-sided membrane cutting structure 6 and the possibility that the cutting edge is consistent with the cutting edge of the single-sided diaphragm structure 6.

[0069] In this embodiment, two guide rods 7-3-3 located in the same vertical plane are horizontally arranged at different heights, two guide rod holes are arranged on the clamping jaw seat 7-2, and the two guide rods 7-3-3 pass through the guide rod holes respectively, and the clamping jaw seat 7-2 is vertically suspended above the double-sided film cutting channel 5-2, and the horizontally arranged clamping jaw 7-1 is parallel to the double-sided film cutting channel 5-2; the position adjustment rod 7-3-2 is arranged between the two guide rods 7-3-3, and is located on the same vertical plane with the two guide rods 7-3-3; the clamping jaw lifting structure 7-5 is realized based on a linear module driven by a servo motor, and the linear module in the clamping jaw lifting structure 7-5 is arranged perpendicular to the ground, and a slide seat 7-4 is arranged on the slide of the linear module driven by the servo motor, and the guide rod 7-3-3 and the shifting cylinder 7-3-1 are respectively fixed on the slide seat 7-4.

[0070] In the present invention, the linear module driven by the servo motor in the clamp lifting structure 7-5 drives the slide seat 7-4 to move in the vertical direction, thereby adjusting the vertical position of the clamp 7-1 fixed on the guide rod 7-3-3, ensuring that the clamp 7-1 can clamp diaphragms of different heights and tighten the clamped diaphragms, thereby improving the practicality of the present invention.

[0071] After the shifting cylinder 7-3-1 is started, it pulls the clamping jaw seat 7-2 fixedly connected to its piston rod, and then pulls the position adjustment rod 7-3-2 fixedly connected to each clamping jaw seat 7-2, so as to adjust the lateral position of each clamping jaw seat 7-2, ensuring that the clamping jaw 7-1 fixed on each clamping jaw seat 7-2 is located between two adjacent bottle bodies 1, reducing the possibility that the clamping jaw 7-1 will fail to clamp the diaphragm 2 due to obstruction by the bottle body 1.

[0072] The jaw rotating structure 7-6 includes a jaw rotating servo motor 7-6-4, which is connected to one end of the jaw rotating shaft 7-6-1 through a reducer 7-6-3 and a coupling 7-6-2. The other end of the jaw rotating shaft 7-6-1 is vertically upwardly arranged on a bearing 7-6-7 and a bearing seat 7-6-5, and is fixedly connected to a rotating connecting plate 7-7; the bottom end of the jaw lifting structure 7-5 is fixed on the rotating connecting plate 7-7.

[0073] In order to ensure that all the clamps 7-1 can clamp the diaphragm 2, the guide rod 7-3-3 is perpendicular to the double-sided film cutting channel 5-2 in the horizontal direction and is suspended above the double-sided film cutting channel 5-2; the hanging direction of the guide rod 7-3-3 is adjusted by the clamp rotating structure 7-6; during adjustment, the clamp rotating servo motor 7-6-4 is started to drive the clamp rotating shaft 7-6-1 to rotate, and the clamp rotating shaft 7-6-1 drives the rotating connecting plate 7-7, the clamp lifting structure 7-5 fixed on the rotating connecting plate 7-7, and the clamp 7-1 to rotate. On the demolding structure 8, after the diaphragm 2 is separated from the bottle body 1, the diaphragm 2 clamped by the clamp 7-1 is rotated and sent into the film collecting structure 13 through the clamp rotating structure 7-6.

[0074] After using the technical solution of the present invention, by respectively arranging a single-sided film cutting knife structure 6 and a double-sided film cutting knife structure 6 on the mutually perpendicular and connected single-sided film cutting channel 5-1 and double-sided film cutting channel 5-2, it is ensured that the three adjacent and mutually perpendicular sides of the diaphragm 2 on the material can contact the hot melt knife; by first cutting one side of the diaphragm 2 in the single-sided film cutting channel 5-1, and then the double-sided diaphragm pushing structure 12 pushes the material, and enters the double-sided film cutting channel 5-2 in the direction of the cut side as the forward direction, and after the film clamping structure 7 is lowered, the clamping claw 7-1 clamps the knife edge of the separated side film 2-3 out, and then the film clamping structure 7 rises to tighten the cut side film 2 The double-sided film cutting drive structure 14 drives the two film cutting knife structures 6 to move in the direction of the single-sided film cutting channel 5-1, ensuring that the two film cutting knife structures 6 cut the side walls of the diaphragm 2 on the two adjacent sides of the separated side films 2-3; because the cutting edge of the single-sided film cutting knife structure 6 has been pulled open, after the height and horizontal position of the double-sided film cutting knife structure 6-1 are adjusted, it can be ensured that the cutting edge of the double-sided film cutting knife structure 6 is consistent with the cutting edge of the single-sided film cutting knife structure 6, thereby ensuring that the three side walls of the top film 2-1 of the diaphragm 2 are completely cut, ensuring the success rate of the subsequent film stripping operation on the film stripping structure 8. In the present invention, by setting the double-sided film cutting drive structure 14, the film cutting knife structure 6 and the film clamping structure 7 do not need to be complicated, and the success rate of the diaphragm is improved.

[0075] When the packaging diaphragm with one side of the diaphragm cut is sent to the entrance of the double-sided film cutting channel, the double-sided diaphragm material pushing structure pushes the material to the bottom of the film clamping structure of the double-sided film cutting channel from the direction perpendicular to the surface of the cut side film; the film clamping structure clamps the opening side of the diaphragm and then rises, and the double-sided film cutting driving structure drives the film cutting knife structures on both sides of the double-sided film cutting channel to move toward the entrance side of the double-sided film cutting channel to cut the sides of the diaphragm from both sides; based on the technical solution of the present invention, after the film clamping structure clamps and tightens the diaphragm cut on the single-sided film cutting channel, the film cutting knife structures on both sides of the double-sided film cutting channel start to work, ensuring that the blades of the two film cuttings are consistent, avoiding the problem of the top diaphragm not being completely cut due to inconsistent blades; at the same time, after the film clamping structure clamps the diaphragm, it will not be pulled by excessive force, avoiding the problem of the clamping claws tearing the diaphragm and the clamping claws failing to clamp; based on the technical solution of the present invention, the film cutting operation on the top of the diaphragm can be accurately completed without complicating the film clamping structure and the diaphragm knife structure.
