Description

Technical Field

[0001] The invention relates to the technical field of diaphragm cutting equipment, in particular to a film cutting structure for a diaphragm stripping device. Background Art

[0002] Many packaging bottles are packed with diaphragms before being filled with liquid or solid contents. Figure 1 As shown, a fixed number of bottles 1 are completely packaged inside a transparent or translucent membrane 2; the packaging membrane 2 includes a top membrane 2-1, a bottom membrane 2-2, and a side membrane 2-3 that are sealed and connected together. Before using the bottle 1 on the production line, the packaging membrane 2 needs to be peeled off first; in the prior art, based on the following Figure 2 The membrane stripping device shown in the figure performs a membrane stripping operation, firstly performs a membrane cutting operation on the three side edges of the top membrane 2-1 of the membrane 2, and then separates the membrane 2 from the bottle body; the specific process is: the bottle body 1 packed in the membrane 2 is placed on the feed port 3, the feeding and pushing structure 9 pushes the bottle body to slide along the single-sided membrane cutting material channel 5-1, and a membrane cutting knife 6 is arranged on one side of the single-sided membrane cutting channel 4. During the sliding process, the side membrane 2-3 on one side of the membrane 2 is cut; the double-sided membrane cutting channel 5-2 is perpendicular to the single-sided membrane cutting channel 5-1 and is connected to each other. ; A double-sided film cutting pushing structure 12 is arranged at the terminal of the single-sided film cutting channel 4 and the entrance of the double-sided film cutting channel 5, and the double-sided film cutting pushing structure 12 continues to push the bottle body 1 into the double-sided film cutting channel 5; a film clamping structure 7 is arranged above the double-sided film cutting channel 5, and the clamping claws of the film clamping structure 7 descend to clamp the separated side films 2-3 and then rise, the side films 2-3 are tightened, and the double-sided film cutting pushing structure 12 continues to push the bottle body 1 forward, and the film cutting knives 6 arranged on both sides below the clamping claws of the film clamping structure 7 continue to perform film cutting operations on both sides of the side films 2-3.

[0003] However, in the process of cutting the top film 2-1 of the diaphragm 2 based on the existing film stripping device, after the clamping claws of the film clamping structure 7 are clamped, the double-sided film cutting pushing structure 12 pushes the bottle body 1 forward, which sometimes causes the clamping claws to tear the diaphragm, and the clamping claws fail to clamp, causing the subsequent film cutting operation to fail; the technician adjusts the position of the film cutting knife 6 on the double-sided film cutting channel 5-2, and performs the film cutting operation before the clamping claws clamp the diaphragm, but the side film 2-3 cut on the single-sided film cutting channel 4 will cause the position of the blade on the diaphragm 2 to change due to relaxation, and the blade position of the film cutting knife 6 on the double-sided film cutting channel 5 and the blade position of the film cutting knife 6 on the single-sided film cutting channel 4 will be inconsistent, and the three sides of the top film 2-1 are not completely cut, which causes the subsequent film stripping structure 8 to separate the bottle body 1 and the diaphragm 2 to fail. Based on the existing structure, whether it is adjusting the clamping structure of the clamping claws or adjusting the blade structure of the film cutting knife 6, the structures of the two will become more and more complicated, and at the same time, the problem of film cutting failure cannot be completely solved.

[0037] like Figure 3 As shown, the present invention is a film cutting structure for a membrane stripping device, which includes: a film cutting knife structure 6, a material channel 5, and a film clamping structure 7; the material channel 5 includes a single-sided film cutting channel 5-1 and a double-sided film cutting channel 5-2 which are perpendicular to each other and connected, the single-sided film cutting channel 5-1 is adjacent to the feed platform 3, and the double-sided film cutting channel 5-2 is away from the feed platform 3, and is connected to the film stripping structure 8 and the discharge platform 4; the film cutting knife structure 6 is installed on the side of the single-sided film cutting channel 5-1 adjacent to the film clamping structure 7, and a film cutting knife structure 6 is symmetrically installed on both sides of the double-sided film cutting channel 5-2; the film clamping structure 7 is arranged above the double-sided film cutting channel 5-2.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] like Figure 4 , Figure 5 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The film cutting knife lifting structure includes: a film cutting knife lifting slider 6-12 vertically arranged on the film cutting knife bracket 6-14, a mounting plate 6-5 fixedly connected to the mounting plate connecting piece 6-9, and the mounting plate connecting piece 6-9 is connected to the film cutting knife lifting slider 6-12 through a slider rail structure; a through hole with an internal spiral is opened on the mounting plate connecting piece 6-9 perpendicular to the film cutting knife lifting slider 6-12, and a lifting tightening nut 6-16 with an adjustment handle is tightened on the film cutting knife lifting slider 6-12 through the through hole; when the vertical position of the film cutting knife 6-1 needs to be adjusted, the lifting tightening nut 6-16 is rotated to loosen the tightening force on the film cutting knife lifting slider 6-12, and after the film cutting knife 6-1 is adjusted in height along with the mounting plate 6-5, the lifting tightening nut 6-16 is tightened to fix the position of the film cutting knife 6-1.

[0048] 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.

[0049] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.
