Figure 1 As shown, a fixed number of bottles 1 are completely packaged in a packaging box 2 with an open top, and the outside and top of the packaging box 2 are sealed by a diaphragm 3. Before using the bottles 1 on the full brake production line, the packaging box 2 and the diaphragm 3 need to be peeled off; in the prior art, the packaging box 2 and the diaphragm 3 are used. Figure 2 The membrane stripping device shown is used to separate the bottle body 1, the membrane 3 and the packaging box 2; the packaged material is placed on the feeding platform 4, and the material linear pushing structure 6 pushes the material to the subsequent workstation for separation operation, and the separated bottle body is sent to the discharging platform 5.

[0034] like Figure 3 As shown, the present invention includes a feeding structure for a box-belt diaphragm stripping device, which includes: an inlet pushing structure 11, a material turning structure 9, a double-sided belt receiving structure 7, and a material linear pushing structure 6, which are sequentially arranged on a material channel 10 between a feeding platform 4 and a discharging platform 5; the material placed on the feeding platform 4 is pushed into the material turning structure 9 based on the inlet pushing structure 11, and after being turned over by the material turning structure 9, the double-sided belt receiving structure 7 sends the material into the feeding position of the material linear pushing structure 6, and continues to be fed through the material linear pushing structure 6, and is sent to the working position of the film cutting structure 12, and then the packaging box 3, the diaphragm 2, and the bottle body 1 are separated through the waste box grabbing structure 13, and the bottle body 1 is sent to the discharging platform 5 for subsequent operations.

[0035] The structure of the turning structure 9 is as follows: Figure 6 , Figure 7 As shown, Figure 7 for Figure 6 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 6 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] like Figure 3 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 5 As shown, the inlet pushing structure 11 includes: a loading positioning structure and a loading pushing structure.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] like Figure 4 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.

[0045] 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.

[0046] like Figure 3 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.

[0047] 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 4 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.

[0048] After the material falls completely onto the corner tray 8-1, the tray lifting cylinder 8-2 is started to lift the material and the corner tray 8-1 to the loading position of the material linear pushing structure 6; in specific implementation, a corner guide plate 8-7 is set on the rising path of the corner tray 8-1 to ensure that the angle of the material will not shift as the corner tray rises; a loading position material presence sensor 8-6 is set, and when the loading position material presence sensor 8-6 detects that there is material at the loading position of the material linear pushing structure 6, the material linear pushing structure 6 is started for subsequent operations.

[0049] like Figure 8As shown, the material linear pushing structure 6 includes: a first conveying plate 6-1, a second conveying plate 6-2, and a fixed pushing plate 6-7 which are arranged perpendicular to and parallel to the material feeding direction on the stripping channel 10-2; the first conveying plate 6-1 and the second conveying plate 6-2 are arranged on the slide of the linear module 6-3 for material pushing, and the travel direction of the slide of the linear module is parallel to the material feeding direction on the stripping channel 10-2 and perpendicular to the material feeding direction of the loading channel 10-1; the first conveying plate 6-1 is driven by the linear module 6-3 for material pushing, and slides between the corner tray 8-1 and the work station of the film cutting structure 12; the distance between the first conveying plate 6-1 and the second conveying plate 6-2 is greater than the length of the material, and the distance between the two is the loading position of the material linear pushing structure 6; the corner tray 8-1 is arranged at a position between the first conveying plate 6-1 and the second conveying plate 6-2.

[0050] The fixed push plate 6-7 is arranged between the first conveying plate 6-1 and the second conveying plate 6-2; the fixed push plate 6-7 is driven by the fixed cylinder 6-8, and moves horizontally between the first conveying plate 6-1 and the second conveying plate 6-2 perpendicular to the second conveying plate 6-2; when the corner tray 8-1 is raised, the material is sent between the first conveying plate 6-1 and the second conveying plate 6-2, and the fixed cylinder 6-8 is started to drive the fixed push plate 6-7 to tighten the material; to ensure that the material will not fall during the transportation process. After the material is tightened, the material push linear module 6-3 drives the first conveying plate 6-1, the second conveying plate 6-2, and the clamped material, along the stripping channel 10-2, and sends the material to the workstation of the film cutting structure 12. Through the cooperation of the material linear push structure 6 and the material corner feeding structure 8, the right-angle bending feeding operation of the material at the corners of the mutually perpendicular channels is completed.

[0051] The linear material pushing structure also includes a conveying plate lifting cylinder 6-6, and the first conveying plate 6-1 and the second conveying plate 6-2 are respectively fixedly connected to the piston ends of the conveying plate lifting cylinder 6-6; the conveying plate lifting cylinder 6-6 is fixed to the slide seat of the linear module 6-3 for material pushing through the conveying connecting frame 6-4; when the material is sent to the working station of the membrane cutting structure 12, the fixing cylinder 6-8 is reversely started, and the fixed push plate 6-7 returns to the default position, and the material is released; the two conveying lifting cylinders 6-6 are started, driving the first conveying plate 6-1 and the second conveying plate 6-2 to rise to a position higher than the material height and then stop, and the material is left at the working station of the membrane cutting structure 12; the linear module 6-3 for material pushing is reversely started, driving the first conveying plate 6-1 and the second conveying plate 6-2 to return to the position above the corner tray 8-1 and then stop, and the loading of the diaphragm structure 12 is completed.

[0052] After using the technical solution of the present invention, the material placed on the feeding platform 4 is pushed into the material turning structure 9 by the entrance pushing structure 11, and the material turning structure 9 turns the material over. The inverted material is taken out from the turning material outlet of the turning structure 9 by the double-sided belt receiving structure 7, and sent to the corner tray 8-1 of the material corner feeding structure 8. The material corner feeding structure 8 sends the material to the loading position of the material linear pushing structure 6, and the material linear pushing structure 6 sends the material to the workstation of the film cutting structure 12 for subsequent operations. The entire loading process does not require workers to manually turn over or manually carry, which not only improves the loading efficiency, but also reduces the probability of material damage caused by manual operation failures.
