[0058] The structure of the turning structure 9 is as follows: Figure 5 , Figure 6 As shown, Figure 6 for Figure 5 A schematic structural diagram of a cross-section along the connecting line of the driven rotating shaft 9-5 and the driving rotating shaft 9-6, that is, Figure 5 The schematic diagram of the structure is a cross-sectional view taken along the AA axis. The turning structure 9 includes: two horizontally arranged fixed conveyor belts 9-1 and a clamping conveyor belt 9-2, a clamping cylinder 9-3, and a rotating drive structure 9-4; the fixed conveyor belt 9-1 and the clamping conveyor belt 9-2 are arranged in parallel up and down in the inner cavity of a U-shaped rotating fixed frame 9-8, and the entrance between the two conveyor belts on the side close to the feeding platform 4 is the turning material entrance, and the side away from the feeding platform 4 is the turning material outlet.

[0059] The rotating fixed frame 9-8 has two side walls perpendicular to the ground, one side wall is fixedly connected to one end of a horizontally arranged driving rotating shaft 9-6, and the other side wall is fixedly connected to one end of a horizontally arranged driven rotating shaft 9-5. In the present invention, the driving rotating shaft 9-6 and the driven rotating shaft 9-5 are located on the same horizontal line; the other end of the driving rotating shaft 9-6 is rotatably fixed on the turning bracket 9-7 through a bearing seat, and then connected to the rotating driving structure 9-4. In the present invention, the rotating driving structure 9-4 includes: a rotating motor, which is connected to the driving rotating shaft 9-6 through a reducer; the other end of the driven rotating shaft 9-5 is connected to the turning bracket 9-7 through a bearing seat. It can be rotatably fixed on the turning bracket 9-7; on the inner sides of the two side walls of the rotating fixed bracket 9-8 perpendicular to the ground, vertical clamping slide rails 9-9 are symmetrically arranged respectively; the fixed conveyor belt 9-1 is fixed in the inner cavity of the rotating fixed bracket 9-8, and the clamping conveyor belt 9-2 is fixedly connected to the horizontally arranged clamping bracket 9-11; a slider 9-10 is arranged on the clamping bracket 9-11, which is slidably connected to the clamping slide rail 9-9 through a slide rail slider structure; in the inner cavity of the rotating fixed bracket 9-8, on a side wall parallel to the ground, a clamping cylinder 9-3 is fixedly arranged, and the piston end of the clamping cylinder 9-3 is vertically connected to the clamping bracket 9-11.

[0060] The driving structure of the fixed conveyor belt 9-1 and the clamping conveyor belt 9-2: the first stepper motor 9-14 and the second stepper motor 9-15 are started, and the fixed conveyor belt 9-1 and the clamping conveyor belt 9-2 rotate in opposite directions; when the material is fed into the material inlet, the rotating conveyor belt 9-1 and the clamping conveyor belt 9-2 feed the material into the inside of the two conveyor belts, and the conveyor belt stops moving after the turning structure detects that the material has reached the preset position with the material laser sensor 9-16; the clamping cylinder 9-3 is started, and the piston end pushes the clamping bracket 9-11 and the clamping conveyor belt 9-2 to slide in the vertical direction along the clamping slide rail 9-9. When the clamping conveyor belt 9-2 moves the preset distance, the clamping cylinder 9-3 stops; the rotating drive structure 9-4 is started , driving the rotating shaft 9-6 to rotate, driving the rotating fixed frame 9-8, the fixed conveyor belt 9-1, the clamping conveyor belt 9-2, and the clamped material to rotate together. When the rotating fixed frame 9-8 rotates to the preset 180-degree position, the rotating driving structure 9-4 stops, the fixed conveyor belt 9-1 and the clamping conveyor belt 9-2 are reversed in the upper and lower positions, and the turning of the material is also completed; the clamping cylinder 9-3 starts in the reverse direction, driving the clamping conveyor belt 9-2 away from the fixed conveyor belt 9-1. When the clamping conveyor belt 9-2 returns to the default position, the clamping cylinder 9-3 is replaced; the first stepper motor 9-14 and the second stepper motor 9-15 continue to start in the previous direction respectively, and the material is transported to the outlet side of the turning material; this turning process is completed.

[0061] On the material entrance side near the feeding platform 4, the upper end surface of the conveyor belt located below is flush with the upper end surface of the feeding platform 4, ensuring that the material pushed from the feeding platform 4 can be directly pushed to the upper end surface of the conveyor belt located below, without the need to adjust the material height structure, thereby simplifying the structure of the system equipment.

[0062] The piston end of the clamping cylinder 9-3 is connected to the clamping bracket 9-11 through a clamping buffer structure, and the clamping buffer structure includes: a clamping buffer spring 9-12, a clamping spring chamber 9-13 fixedly connected to the clamping bracket 9-11, and a through hole is opened on the side wall of the clamping spring chamber 9-13 opposite to the clamping bracket 9-11; an inverted T-shaped structure is arranged at the top of the piston rod of the clamping cylinder 9-3, and the head width of the inverted T-shaped structure is greater than the diameter of the convex through hole, and the clamping buffer spring 9-12 is arranged in the inner cavity of the clamping spring chamber 9-13, and the two ends are respectively mortgaged to the clamping cylinder 9-3 The piston end head and the clamping bracket 9-11; when the clamping cylinder 9-3 is started, the piston end first pushes the clamping buffer spring 9-12, causing the clamping buffer spring 9-12 to be compressed and deformed, and then the clamping buffer spring 9-12 pushes the clamping bracket 9-11 and the clamping conveyor belt 9-2 to slowly slide in the vertical direction along the clamping slide rail 9-9; through the setting of the clamping buffer spring 9-12, a sudden force is applied, causing the clamping conveyor belt 9-2 to suddenly press against the fixed conveyor belt 9-1, causing the packaging box 3 and the bottle body 1 in the material sandwiched between the two to be strongly compressed and damaged.

[0063] like Figure 2 As shown, the inlet pushing structure 11 is arranged on the upper end surface of the feeding platform 4, and its pushing stroke is between the feeding platform 4 and the material turning structure 9; Figure 4 As shown, the inlet pushing structure 11 includes: a loading positioning structure and a loading pushing structure.

[0064] The feeding and pushing structure includes: an inlet feeding push plate 11-1 and an inlet pushing rodless cylinder 11-2. The inlet feeding push plate 11-1 is arranged on the upper end surface of the feeding platform 4 perpendicular to the material feeding direction; the inlet feeding push plate 11-1 is fixed to the slide seat of the inlet pushing rodless cylinder 11-2 to push the material along the feeding channel.

[0065] The loading positioning structure includes: an inlet positioning fixed plate 11-5 and an inlet positioning push plate 11-4 parallel to the material feeding direction. The inlet positioning fixed plate 11-5 is fixedly arranged on the top surface of the feeding platform 4, and the inlet positioning push plate 11-4 is pushed by the inlet positioning cylinder 11-3 to move perpendicular to the material feeding direction; in the present invention, the inlet loading push plate 11-1 is arranged on the inlet positioning fixed plate 11-5 and the inlet positioning push plate 11-4.

[0066] The material is placed by the feeding device to the position between the entrance feeding push plate 11-1 and the turning structure 9 on the upper end surface of the feeding platform 4. After the material laser sensor 11-6 on the feeding platform detects the presence of material, the entrance positioning cylinder 11-3 is started, and the entrance feeding push plate 11-1 pushes the material until the material is pushed to a side close to the entrance positioning fixed plate 11-5. At this time, the material is positioned to the position of the turning material entrance aligned with the turning structure 9 in the material feeding direction; the entrance positioning cylinder 11-3 stops, and then starts in reverse to bring the entrance feeding push plate 11-1 back to the default position on the side of the feeding platform 4; the entrance pushing rodless cylinder 11-2 is started, and the entrance positioning push plate 11-4 is pushed along the material feeding direction, and the material is pushed to the turning material entrance between the rotating conveyor belt 9-1 and the clamping conveyor belt 9-2, completing the feeding of the turning structure 9 without manual feeding, thereby improving operating efficiency.

[0067] like Figure 3 As shown, the double-sided belt material receiving structure 7 is arranged between the material turning structure 9 and the material linear pushing structure 6; the double-sided belt material receiving structure 7 includes: a material receiving motor 7-3, a horizontally arranged strip belt 7-1; two strip belts 7-1 are arranged in parallel on the material channel, and the distance between the two is less than or equal to the width of the material; the strip belts 7-1 are driven to rotate synchronously through the transmission shaft 7-2, and the output shaft of the material motor 7-3 is connected to the transmission shaft 7-2; one end of the strip belt 7-1 is arranged on the discharge side of the material turning structure 9, close to the turning material outlet of the turning structure 9, and the other end is arranged on the loading side of the material linear pushing structure 6; the strip belt 7-1 is driven by the material receiving motor 7-3 to transmit from the material turning structure 9 to the loading position of the material linear pushing structure 6.

[0068] When the material is sent out from the turning material outlet of the turning structure 9 by the rolling solid conveyor belt 9-1 and the clamping conveyor belt 9-2, it falls onto the horizontally arranged strip belt 7-1, and the strip belt 7-1 is driven by the material receiving motor 7-3 to rotate in the material feeding direction, and the material is driven by the strip belt 7-1 to continue to be transmitted forward; because the turned over material has the diaphragm 3 downward, the friction of the diaphragm 3 is relatively large, so the two strip belts provide transmission force to 7-1 and send it to the next workstation. There is no table structure in the middle of the belt, which can reduce the complexity of the system structure, and can also reduce the friction between the diaphragm 3 and the contact surface, making the transmission more labor-saving.

[0069] like Figure 2 As shown, the material channel 10 in the present invention includes two mutually connected and perpendicular channels: a loading channel 10-1 and a stripping channel 10-2. The loading channel 10-1 is connected to the feeding platform 4 and the workstation of the turning structure 9, and the stripping channel 10-2 is connected to the discharging platform 5. By means of the mutually perpendicular loading channel 10-1 and the stripping channel 10-2, the floor space of the entire device is reduced, ensuring that the device is more suitable for different factory buildings.

[0070] In order to realize the feeding at the corners of mutually perpendicular channels, a material corner feeding structure 8 is provided at the connection between the feeding channel 10-1 and the stripping channel 10-2; Figure 3 As shown, the material corner feeding structure 8 includes: a corner tray 8-1 and a tray lifting cylinder 8-2 are horizontally arranged on a corner tray bracket 8-4, the corner tray 8-1. The bottom end of the corner tray 8-1 is connected to the piston end of the tray lifting cylinder 8-2, and a vertical tray guide linear bearing 8-5 is arranged at the bottom end of the corner tray 8-1 to ensure that the corner tray 8-1 is lifted and lowered smoothly without shaking, thereby damaging the material; the corner tray 8-1 is arranged next to the strip belt 7-1; in the technical solution of the present invention, the area of ​​the corner tray 8-1 is smaller than the bottom area of ​​the material. In the default position of the corner tray 8-1, the upper end surface of the corner tray 8-1 is lower than the upper end surface of the strip belt 7-1; a feeding guide plate 8-3 is arranged on the outer side of the strip belt 7-1 in parallel with the two strip belts 7-1 to ensure that the material is lifted from the strip belts When 7-1 falls to the corner tray 8-1, there will be no angle deviation due to accidents; the strip belt 7-1 drives the material forward along the material feeding direction. After the front end of the material exceeds the strip belt 7-1, it will sag due to gravity, and then be caught by the corner tray 8-1 which is set at an adjacent position but lower than the strip belt 7-1. The strip belt 7-1 continues to provide forward force for the material until the material completely falls onto the corner tray 8-1; because the bottom end of the material is completely the diaphragm 3 at this time, a large friction force will be generated during the movement; at the default material receiving position of the corner tray 8-1, the upper end face of the corner tray 8-1 is set lower than the upper end face of the strip belt 7-1, and the friction force is offset by gravity. No additional force-applying structure is required to transfer the material to the corner tray 8-1, which greatly simplifies the structure of the system.

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.

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.

[0082] 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.

[0083] like Figure 8 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.

[0084] 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.

[0085] 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 8 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.

[0086] 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.

[0087] The U-shaped waste film protection cover 12-4-4 is connected to the piston end of the protection cover lifting cylinder 12-4-3, and the protection cover lifting cylinder 12-4-3 is fixedly connected to the swing connection seat 12-2; the waste film protection cover 12-4-4 is driven by the protection cover lifting cylinder 12-4-3 and moves vertically above the cutter structure 12-3. The preset position of the waste film protection 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 protection cover lifting cylinder 12-4-3 is activated to lower the waste film protection cover 12-4-4 until the waste film protection 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 generate fragments that fall on the film cutting operation table 12-11, resulting in the failure of subsequent film cutting operations; in the present invention, during the process of recycling the diaphragm waste, the cutter body 12-3-1 is completely shielded inside the protection cover 12-4-4, preventing the film cutting waste from being broken again and ensuring that the film cutting process can be accurately completed.

[0088] In the technical solution of the present invention, the diaphragm waste remaining on the diaphragm structure is lifted by the waste film lifting structure, the diaphragm waste is grabbed by the waste film clamping jaw, and the waste film clamping jaw and the grabbed diaphragm waste are driven by the film cutting knife swing drive structure and sent to the waste box; the technical solution of the present invention utilizes the original film cutting knife swing drive structure of the film cutting structure, and through the waste film lifting structure and the waste film clamping jaw, realizes the process of grabbing and transporting the diaphragm waste to the waste box, without the need to separately set up a structure for picking up the diaphragm, effectively reducing the floor area of the diaphragm system, simplifying the system structure, and at the same time improving the working efficiency of the overall diaphragm peeling device.

[0089] As Fig.11 、 Fig.12 shown, the material linear pushing structure 6 pushes the material along the material channel 10 to the working position of the film cutting structure 12.

Two clamping slide rails 13-3 are respectively arranged in the movement direction of the piston of the cylinder 13-2. The top surfaces of the two waste box clamping plates 13-1 are respectively slidably connected to the clamping slide rails 13-3 through the slide rail slider structure. The clamping slide rails 13-3 ensure that the two waste box clamping plates 13-1 can move smoothly in the horizontal direction; the farthest distance between the two waste box clamping plates 13-1 is greater than the width between the two clamped side walls of the packaging box 2, ensuring that the two waste box clamping plates 13-1 can clamp the side walls of the packaging box 2 from both sides. The vertical default position of the waste box clamping plate 13-1 is directly above the station of the waste box separation structure, which will not affect the height of the material entering the station of the waste box separation structure. The default distance between the two waste box clamping plates 13-1 is the maximum separation distance.

[0091] The waste box lifting structure includes a box taking lifting cylinder 13-5, the piston end of which is vertically downwardly arranged, and the piston end of which is fixedly connected to the top surface of the lifting connecting plate 13-6, driving the waste box clamping structure to perform lifting movement.

The linear module 13-4 is realized based on a device capable of realizing linear drive in the prior art, such as a module based on a synchronous belt type, a ball screw type, a linear motor type, or a cylinder. The linear module in this embodiment is realized based on a linear module driven by a servo motor. The linear module 13-4 drives the waste box clamping structure, the clamped packaging box 2, and the diaphragm 3 to move between the workstation of the waste box separation structure and the waste box 14 through the horizontally moving slide 13-10, thereby clamping the packaging box 2 and placing the packaging box 2 and the diaphragm 3 into the waste box 14.

[0093] A horizontal moving guide rail 13-11 is arranged at the bottom end of the horizontal moving slide 13-10. The horizontal moving guide rail 13-11 is arranged parallel to the movement direction of the horizontal moving slide 13-10 of the linear module 13-4. The bottom end of the horizontal moving slide 13-10 is slidably connected to the horizontal moving guide rail 13-11 through a slider rail structure. When the horizontal moving slide 13-10 drives the waste box clamping structure to move horizontally, the horizontal moving slide 13-10 is supported by the horizontal moving guide rail 13-11 to achieve smooth movement.

[0094] The waste box separation structure of the present invention also includes a shaking structure, which includes: a shaking cylinder 13-7, the shaking cylinder 13-7 is arranged on the horizontal moving slide 13-10 of the linear module 13-4 for horizontal movement of the waste box, and the waste box lifting structure is connected to the piston rod of the shaking cylinder 13-7; the piston rod of the shaking cylinder 13-7 in the present invention is arranged horizontally, and the waste box lifting structure is driven by the shaking cylinder 13-7 to move in the horizontal direction; the shaking guide rail 13-8 is parallel to the moving direction of the piston rod of the shaking cylinder 13-7 and is arranged on the upper end surface of the horizontal moving slide 13-10, the waste box lifting structure is fixedly connected to one end of the horizontal connecting plate 13-9, and the other end of the horizontal connecting plate 13-9 is connected to the piston end of the shaking cylinder 13-7; the bottom end of the horizontal connecting plate 13-9 is slidably connected to the shaking guide rail 13-8 through a slider rail structure. After the shaking cylinder 13-7 is started, the waste box lifting structure moves in the horizontal direction through the horizontal connecting plate, and the shaking guide rail 13-8 supports the horizontal connecting plate 13-9 to slide smoothly on the upper end surface of the horizontal moving slide 13-10, ensuring the overall balance during sliding.

[0095] Based on the technical solution of the present invention, when it is necessary to separate the packaging box 2 and the bottle body 1, the box-taking lifting cylinder 13-5 is started, driving the waste box clamping plate 13-1 to drop from the default position to the outside of the top ends of the two side walls of the packaging box 2, and the two waste box clamping cylinders 13-2 are started, driving the two waste box clamping plates 13-1 to clamp the top ends of the two opposite side walls of the packaging box 2 from both sides and then stop; the shaking cylinder 13-7 is started, driving the waste box lifting structure, the packaging box 2, and the diaphragm 3 to slide a short distance in the horizontal direction along the shaking guide rail 13-8, and then the shaking cylinder 13-7 is started in the reverse direction, driving the waste box lifting structure, the packaging box 2, and the diaphragm 3 to slide in the reverse direction in a very short distance along the shaking guide rail 13-8 in the horizontal direction. Through several short-distance horizontal repeated sliding in a short time, the shaking effect of the packaging box 2 and the diaphragm 3 is achieved, so that the diaphragm 3, the packaging box 2 and the bottle body 1 packed therein are separated. Separation ensures that in the subsequent lifting and lowering movement, the diaphragm 3 and the packaging box 2 will not drive the bottle body 1 to rise and fall at the same time due to friction; the specific number of repeated horizontal movements of the shaking cylinder 13-7 is set according to the material and weight of the bottle body 1; after the shaking is completed, the box-taking lifting cylinder 13-5 starts in the reverse direction, drives the packaging box 2 to rise to the default height position and then stops; the linear module 13-4 is started, and the horizontal moving slide 13-10 drives the clamped diaphragm 3 and packaging box 2 to move horizontally until they move to the top of the opening of the waste bin 14 and then stop; the two waste box clamping cylinders 13-2 start to start in the reverse direction, drive the two waste box clamping plates 13-1 to move to the default position on both sides and then stop, the packaging box 2 and the diaphragm 3 are released and fall into the waste bin 14; the linear module 13-4 starts to start in the reverse direction, drives the two waste box clamping plates 13-1 back to the default position, and this waste box separation operation is completed.

[0097] like Fig.13As shown, the material discharging and transferring structure 15 includes: a conveying belt 15-1, a belt driving structure, and an anti-jumping plate 16; the belt driving structure includes: a belt driving servo motor 15-3, and a belt speed regulating motor 15-4; driven by the belt driving structure, the conveying belt 15-1 conveys materials between the discharging platform 5 and the working station of the cutting knife structure 12; positioning bars 15-2 are respectively arranged on both sides of the conveying belt 15-1, and the distance between the two positioning bars 15-2 is adapted to the width of the material. The positioning bars 15-2 ensure that during the process of conveying materials by the conveying belt 15-1, the material will not change its angle or position due to external force.

[0098] The anti-jumping plate 16 is fixed above the conveying belt 15-1 beside the station of the waste box separation structure 13 through an anti-jumping plate bracket 16-1; the anti-jumping plate 16 is a flat plate structure arranged parallel to the conveying belt 15-1, and the distance between the anti-jumping plate 16 and the upper end surface of the conveying belt 15-1 is greater than the height of the bottle body, and upward discarded warped edges are respectively arranged on the two side edges where materials enter and exit, ensuring that the materials can smoothly enter and exit the bottom of the anti-jumping plate 16;.

[0099] The material linear pushing structure 6 pushes the material along the material channel 10 to the station of the film cutting structure 12. The film cutting structure 12 completes the film cutting operation on the diaphragm 3. The material linear pushing structure 6 comes to the film cutting operation table 12-11, and pushes the bottle body 1, the packaging box 2, and the diaphragm 3 on the top of the packaging box 2 along the material channel 10 to the conveyor belt 15-1. The conveyor belt 15-1 drives the material to move toward the waste box separation structure 13; when the waste box separation structure 13 separates the bottle body 1, the packaging box 2, and the diaphragm 3 on the top of the packaging box 2 at its station During operation, the material after the diaphragm operation of the membrane cutting structure 12 is driven by the conveying belt 15-1 to the position below the anti-jumping plate 16. The anti-jumping plate 16 is slightly higher than the height of the material, so as to avoid the situation in which the lifting cylinder 13-5 in the waste box separation structure 13 drives the packaging box 2 and the diaphragm 3 on the top of the packaging box 2 to rise, causing the packaging box 2 and the diaphragm 3 of the waiting material to move in position, thereby avoiding the problem that the waste box clamping plate 13-1 fails to clamp the packaging box 2 due to the movement of the position of the packaging box 2 when the waste box separation operation is performed on the waiting material.

[0100] After the waste box separation structure 13 has finished separating the bottle body 1, the packaging box 2, and the diaphragm 3 at its station, the bottle body 1 at the station of the waste box separation structure 13 is driven by the conveying belt 15-1 and continues to move forward until it is conveyed to the discharge platform 5, completing the process of peeling the packaging box 2 and the diaphragm 3 from the bottle body 1. In specific implementation, the discharge platform material laser sensor 18 is used to confirm whether there is material on the discharge platform 5, and then the belt driving structure is linked.

[0101] The box-belted membrane peeling machine provided by the present invention can peel off the membrane and the packaging box quickly, efficiently and accurately. The entire process does not require manual operation by workers, which not only improves the separation efficiency of the bottle body, the packaging box and the membrane, but also reduces the processing cost as a whole.
