Description

Technical Field

[0001] This invention belongs to the technical field of wine box processing equipment, specifically relating to an automatic bagging machine. Background Technology

[0002] Currently, most wine box bagging is done manually. This method requires a separate bag-making machine to pre-make plastic bags, which are then manually filled in. This method is inefficient, wastes a lot of manpower, and results in high costs. Therefore, wine box bagging machines have emerged on the market. However, most existing wine box bagging machines use suction cups to open the bags when the film roll is opened, which can lead to incomplete opening. Incomplete opening can affect the bagging of the wine box, easily causing bagging failure, requiring machine downtime for adjustment, and significantly impacting the overall bagging efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic bagging machine that addresses the shortcomings of the prior art, thereby ensuring successful opening of the bag every time the film roll is opened, thus effectively improving the overall efficiency of bagging.

[0004] The technical solution adopted in this invention is as follows: an automatic bagging machine, including a frame, a horizontally arranged fixed support plate installed in the middle of the front side of the frame, and a vertically arranged fixed mounting plate symmetrically installed on the rear side of the fixed support plate. A film feeding shaft is installed in the middle of one end of the front side of the fixed mounting plate. The rear end of the film feeding shaft passes through the fixed mounting plate and is connected to a servo motor. A roll of film is fixedly mounted on the film feeding shaft. A bag forming mechanism is installed at the top of the middle of the front side of the fixed mounting plate. Several conveying rollers are installed between the film feeding shaft and the bag forming mechanism. The conveying roller at the end is located directly above the middle of the bag forming mechanism. A sealing assembly is symmetrically arranged below the bag forming mechanism with its centerline in mind. A bag supporting mechanism is also provided below the bag forming mechanism. A lifting mechanism is connected to the back of the bag supporting mechanism. The lifting mechanism is fixedly installed on the back of the fixed mounting plate. The vertical centerlines of the bag supporting mechanism and the bag forming mechanism coincide.

[0005] The fixed support plate is sequentially equipped with a feeding conveyor belt, a bagging conveyor belt and a discharging conveyor belt along its length. A feeding photoelectric sensor is installed on one side of the end of the feeding conveyor belt. A positioning mechanism is installed above the bagging conveyor belt and a clamping mechanism is installed below it. The positioning mechanism and the lifting mechanism are both corresponding to the positions of the bagging mechanism. A lifting mechanism is installed at the bottom of the clamping mechanism.

[0006] The bag-forming mechanism includes two symmetrically arranged support rollers. A bag-opening roller is installed between the tops of the two support rollers and rolls with them. The two bag-opening rollers are connected by a connector, and the two ends of the two bag-opening rollers are rotatably engaged with the connector. The bottom of the connector passes between the two support rollers and is connected to a bag-forming component. The bottom of the bag-forming component is open, and two corresponding notches are opened on both sides of the bottom of the bag-forming component. A number of limiting rollers are symmetrically installed on both sides of the outer wall of the bag-forming component and distributed along the vertical direction of the bag-forming component. The vertical center lines of the bag-forming component, the two bag-opening rollers, the two support rollers, and the number of limiting rollers coincide.

[0007] The bag-supporting mechanism includes a bag-supporting plate parallel to the fixed mounting plate. A lifting mechanism is installed on the back of the bag-supporting plate. Bag-supporting connecting seats that can slide synchronously are symmetrically installed on both sides of the front of the bag-supporting plate. A bag-supporting support frame is fixedly connected to the front of each bag-supporting connecting seat. Two bag-supporting rods are installed on each bag-supporting support frame. The distance between the two bag-supporting rods corresponds to the distance between the two notches on the same side of the bag. A horizontal clamping rod is also provided on the upper part of each bag-supporting rod. A clamping cylinder is connected to the end of the clamping rod away from the bag-supporting rod.

[0008] The clamping mechanism includes a clamping seat, the bottom of which is connected to a lifting mechanism. A low clamping plate and a high clamping plate are respectively provided on both sides of the clamping seat along the conveying direction of the bag-covering conveyor belt. The top surface of the low clamping plate is lower than the top surface of the high clamping plate. A clamping cylinder is connected to the bottom inner side of the low clamping plate and the high clamping plate respectively.

[0009] Preferably, the several conveyor rollers are sequentially divided into a guiding zone, a film stretching zone, and a film pressing zone along the film conveying direction. The guiding zone includes two conveyor rollers close to the film unwinding shaft. The film stretching zone is located above the guiding zone and includes three evenly spaced and horizontally distributed conveyor rollers. An adjusting guide rail is vertically fixed on the centerline between the two conveyor rollers close to the guiding zone. An adjusting slide is mounted on the adjusting guide rail to match its sliding movement. A free roller aligned with the direction of the conveyor rollers is mounted on the adjusting slide. A stretching guide rail is vertically mounted on the centerline between the two conveyor rollers away from the guiding zone. A stretching slide is installed on the upper part of the conveyor roller, and a stretching roller with the same direction as the conveyor roller is installed on the stretching slide. A stretching cylinder is installed below the stretching slide. The film pressing area is installed near the bag forming mechanism and includes two conveyor rollers on the same horizontal line as the conveyor roller of the film pressing area. The tail conveyor roller is located directly above the middle of the bag forming mechanism. A film pressing fixing plate with the top of the conveyor roller is installed between the two conveyor rollers. A film pressing cylinder is installed above the film pressing fixing plate. A film pressing movable plate corresponding to the film pressing fixing plate is installed at the bottom of the film pressing cylinder.

[0010] Preferably, the sealing assembly includes a sealing support plate, a sealing guide rail is mounted on the surface of the sealing support plate, a sealing slide seat is provided on the sealing guide rail and slide seat that slides with it, a heat sealing knife is mounted on the side of the sealing slide seat near the bag forming mechanism, and a sealing cylinder is mounted on the side away from the bag forming mechanism. A cutting knife is also provided inside the heat sealing knife of one of the sealing assemblies, and the cutting knife extends out from both sides of the heat sealing knife and is respectively connected to a cutting cylinder.

[0011] Preferably, the feeding conveyor belt, the bagging conveyor belt, and the discharging conveyor belt are equipped with limiting baffles on both sides that match the width of the wine box to be bagged.

[0012] Preferably, a limiting component is provided at the end of the feeding conveyor belt. The limiting component includes limiting bars respectively located on both sides of the feeding conveyor belt. Several limiting wheels are fitted on the limiting bars along their length. An annular groove is opened in the middle of the outer wall of the limiting wheel, and an annular limiting rubber ring is engaged in the annular groove. The outer wall of the engaged limiting rubber ring protrudes from the outer wall of the limiting wheel. The distance between the two corresponding limiting wheels on the two limiting bars corresponds to the wine box to be bagged. The tops of the two limiting bars are connected to a driving mechanism through synchronous driving gears.

[0013] Preferably, the positioning mechanism includes a fixed positioning card and a movable positioning card. The positioning area formed by the fixed positioning card and the movable positioning card is located directly below the bag forming mechanism. A positioning cylinder is installed on the side of the movable positioning card away from the fixed positioning card.

[0014] The beneficial effects of this invention are as follows:

[0015] (1) It is equipped with a bag forming component and uses free rollers and film pulling rollers to adjust the film conveying. This ensures that after each bag making is completed and cut, the opening of the film roll can return to the bottom of the bag forming component, thus effectively ensuring the opening at the end of the film roll, which achieves 100% film roll opening.

[0016] (2) The bag assembly ensures the opening of the roll film. The notches on both sides are matched with the extended bag support rod and the clamping rod that cooperates with the bag support rod. The clamping rod can press the roll film onto the bag support rod to complete the clamping of the open roll film, which is conducive to pulling the roll film out to make bags later.

[0017] (3) The lifting, closing, and separation of the four bag-supporting rods are all achieved through pure mechanical transmission, which reduces the bag-supporting action and improves bag-making efficiency.

[0018] (4) A limit component and a feeding photoelectric sensor are set at the end of the feeding conveyor belt. With the cooperation of the limit component and the feeding photoelectric sensor, the wine box can be limited and waited for, that is, one bag is conveyed at a time.

[0019] (5) The positioning mechanism is set to position and clamp the wine box after it is in place, which ensures that the subsequent clamping mechanism accurately clamps the wine box. The wine box is in a clamped state to complete the bagging, which reduces the chance of collision with the machine and improves the stability of equipment operation.

[0020] (6) A low-position clamping plate and a high-position clamping plate are cleverly designed. By utilizing the height difference between the low-position clamping plate and the high-position clamping plate, the low-position clamping plate can avoid the wine box input without affecting the input of the wine box. At the same time, the extended high-position clamping plate is used to limit the wine box to the correct position. With the help of the positioning photoelectric sensor, the wine box is detected by the positioning photoelectric sensor when it reaches the high-position clamping plate. The positioning photoelectric sensor then sends a signal to control the bagging conveyor belt to stop, thus completing the wine box positioning work.

[0021] This invention achieves 100% bag opening through a mechanical structure, effectively improving the efficiency of bagging. At the same time, the bagging process is simple and involves fewer steps, effectively improving the reliability of equipment operation. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] Example

[0039] like Figures 1-14 As shown, the automatic bagging machine provided in this embodiment includes a frame 1, a horizontally arranged fixed support plate 2 is installed in the middle of the front side of the frame 1, and a vertically arranged fixed mounting plate 3 is symmetrically installed on the rear side of the fixed support plate 2.

[0040] A film-laying shaft 4 is installed at the middle of one end of the front side of the fixed mounting plate 3. The rear end of the film-laying shaft 4 passes through the fixed mounting plate 3 and is connected to a servo motor. The servo motor is fixed on the back side of the fixed mounting plate 3. A roll of film 5 is fixedly fitted on the film-laying shaft 4.

[0041] A bag-forming mechanism 6 is installed at the top of the middle of the front side of the fixed mounting plate 3. Several conveying rollers are installed between the film-laying shaft 4 and the bag-forming mechanism 6. Along the conveying direction of the roll film 5, the several conveying rollers are sequentially divided into a guiding area 7, a film-pulling area 8, and a film-pressing area 9. The guiding area 7, the film-pulling area 8, and the film-pressing area 9 are all installed on the front side of the fixed mounting plate 3.

[0042] The guide area 7 consists of two conveying rollers close to the film-laying shaft 4;

[0043] The stretching zone 8 is located above the guide zone 7 and includes three evenly spaced and horizontally distributed conveyor rollers. An adjusting guide rail 801 is vertically fixed on the centerline between the two conveyor rollers closest to the guide zone 7. An adjusting slide block 802 is installed on the adjusting guide rail 801 to slide with it. A free roller 803 aligned with the direction of the conveyor rollers is installed on the adjusting slide block 802. A stretching guide rail 804 is vertically installed on the centerline between the two conveyor rollers furthest from the guide zone 7. A stretching slide block 805 is installed on the stretching guide rail 804 to slide with it. A stretching roller 806 aligned with the direction of the conveyor rollers is installed on the stretching slide block 805. A stretching cylinder 807 is installed below the stretching slide block 805. The driving end of the stretching cylinder 807 is fixedly connected to the bottom of the stretching slide block 805. The lowest position of the adjusting slide block 802 is lower than the lowest position of the stretching slide block 805.

[0044] The film pressing area 9 is installed close to the bag forming mechanism 6. It includes two conveying rollers that are on the same horizontal line as the conveying rollers of the film stretching area 8. One of the conveying rollers is located directly above the middle of the bag forming mechanism 6. A film pressing fixing plate 901 that is flush with the top of the film rolling roller 5 is installed between the two conveying rollers. A film pressing cylinder 902 is installed above the film pressing fixing plate 901. A film pressing movable plate 903 corresponding to the film pressing fixing plate 901 is installed at the bottom of the film pressing cylinder 902.

[0045] The roll film 5 passes through the two conveyor rollers in the guide area 7, then around the first conveyor roller in the stretching area, then around the free roller 803, then around the conveyor roller in the middle of the stretching area, then around the stretching roller 806, and then through the last conveyor roller in the stretching area to the pressing area 9. It then passes through the first conveyor roller, the pressing plate 901, and the last conveyor roller in the pressing area 9 before reaching the bag forming mechanism 6. The roll film 5 is in a W-shaped form in the stretching area and is horizontal in the pressing area 9.

[0046] The bag-forming mechanism 6 includes two symmetrically arranged support rollers 601, each support roller 601 having two limiting rings 602 fitted on it. The distance between the two limiting rings 602 corresponds to the width of the roll film 5. A bag-opening roller 603 is installed between the tops of the two support rollers 601, engaging with them in a rolling manner. The bag-opening roller 603 is located between the two limiting rings 602 and is connected to the two bag-opening rollers 603 by a connector 604. The two ends of the two bag-opening rollers 603 are rotatably engaged with the connector 604. The bottom of the connector 604 passes between the two support rollers 601 and connects to a bag-forming component 605. The bag-forming component 605 has an open bottom, and two corresponding notches 606 are opened on both sides of the bottom of the bag-forming component 605. The distance between the notches 606 on the same side is slightly larger than the side length of the wine box. In this embodiment, the bag-forming component 605 adopts a rectangular shell. A number of limiting rollers 607 are symmetrically installed on both sides, distributed vertically along the bag forming component 605. A gap of the thickness of a single layer of roll film 5 is left between the limiting rollers 607 and the bag forming component 605. The inner sectional surface of the limiting rollers 607 and the inner sectional surface of the support rollers 601 are located on the same vertical plane. The vertical center lines between the bag forming component 605, the two opening rollers 603, the two support rollers 601, and the number of limiting rollers 607 coincide. The center line between the two opening rollers 603 coincides with the center line of the roll film 5 roller above it. After the roll film 5 passes through the roll film 5 roller, it is opened manually for the first time. One side of the bag opening passes between the left support roller 601 and the opening roller 603, and the other side of the bag opening passes between the right support roller 601 and the opening roller 603. Then, the two sides of the bag opening pass through the gap between the limiting rollers 607 and the bag forming component 605, and the bag opening extends out of the bottom of the bag forming component 605.

[0047] The fixed mounting plate 3 has a clearance groove that runs through the bottom of the fixed mounting plate 3 directly below the bag forming mechanism 6. A lifting support plate 1201 is provided on the back of the fixed mounting plate 3 at the location corresponding to the clearance groove. The two sides of the lifting support plate 1201 are connected to the back of the fixed mounting plate 3 by connecting rods. A vertical lifting screw 1202 is installed on the front of the lifting support plate 1201 at the location corresponding to the vertical center line of the bag forming mechanism 6. Lifting guide rails 1203 are symmetrically installed on both sides of the lifting screw 1202. A servo motor is connected to the top of the lifting screw 1202. A lifting support seat 1204 with a threaded fit is fitted on the lifting screw 1202. The two sides of the support seat are respectively connected to the lifting guide rails 1203 through lifting slides 1205.

[0048] A bag support plate 1101 perpendicular to the lifting support plate 1201 is installed on the side of the lifting support plate 1201 away from the lifting screw 1202. Horizontal bag support slide rails 1102 are respectively installed on the top and bottom of the front of the bag support plate 1101. Two bag support slide seats 1103 that slide together are installed on each bag support slide rail 1102. Vertical bag support connecting seats 1104 are installed on the two bag support slide seats 1103 on the same side. The two bag support connecting seats 1104 correspond to each other, and the lower part of one of the bag support connecting seats 1104 is fixed. A horizontally arranged rack 1105 is connected, with a rack 1105 clearance hole 1106 on the upper part. Another bag support connecting seat 1104 has a rack 1105 clearance hole 1106 on the lower part and a horizontally arranged rack 1105 fixedly connected to the upper part. A bag support gear 1107 that meshes with both racks 1105 is provided at the center line between the two bag support connecting seats 1104. A rotating shaft is connected to the center of the back of the bag support gear 1107. The rotating shaft passes through the bag support plate 1101 and is connected to a servo motor. The servo motor is fixed on the lifting support plate 1201.

[0049] Each of the bag support connecting seats 1104 is fixedly connected to a bag support frame 1108 on its front side. Each bag support frame 1108 is equipped with two bag support rods 1109. The distance between the two bag support rods 1109 corresponds to the distance between the two notches 606 on the same side of the bag component 605. At the same time, there is also an clearance opening between the two bag support rods 1109 that matches the side length of the wine box. Each bag support rod 1109 is also provided with a horizontal clamping rod 1110 on its upper part. The end of the clamping rod 1110 away from the bag support rod 1109 is connected to a clamping connecting seat. A clamping cylinder 1111 is connected to the clamping connecting seat and is fixed to the bag support frame 1108.

[0050] When the lifting support plate 1201 is at its highest point, the two bag support frames 1108 are closest to each other. At this time, the four bag support rods extend into the bag forming component 605, and each bag support rod corresponds to a notch 606 in the bag forming component 605.

[0051] When the relative positions of the two bag support brackets 1108 are at their farthest, the outline formed by the clearance grooves of the two bag support brackets 1108 is slightly larger than the wine box.

[0052] The fixed mounting plate 3 is also symmetrically equipped with sealing film assemblies 10. Two sealing film assemblies 10 are located near the bottom of the bag forming mechanism 6 and symmetrically arranged on both sides of the bag forming mechanism 6. Each sealing film assembly 10 includes a sealing film support plate 1001, a sealing film guide rail 1002 mounted on its surface, and a sealing film slide block 1003 slidably fitted onto the sealing film guide rail 1002. A heat sealing knife 1004 is mounted on the side of the sealing film slide block 1003 closest to the bag forming mechanism 6, and a sealing film cylinder 1005 is mounted on the side furthest from the bag forming mechanism 6. One of the... The sealing assembly 10 also includes a cutting blade 1006 inside the heat-sealing blade 1004. The cutting edge of the cutting blade 1006 is located inside the heat-sealing blade 1004. The cutting blade 1006 extends out from both sides of the heat-sealing blade 1004 and is connected to a cutting cylinder 1007. The two cutting cylinders 1007 are fixed on both sides of the sealing slide 1003. After the bag is put on, the two sealing cylinders 1005 push the corresponding heat-sealing blades 1004 closer together and close to complete the heat sealing. After the heat sealing is completed, the cutting cylinders 1007 extend to control the cutting blade 1006. The pocket film above the seal is cut to complete the heat-sealing cutting process. Then, the cutting cylinder 1007 and the sealing cylinder 1005 retract to their initial positions. Because the cutting cylinder 1007 and the heat-sealing knife 1004 continuously reciprocate, the wire harness connected to them will move continuously, making the wire harness connectors prone to damage. Furthermore, different wire harnesses are prone to tangling and knotting during continuous movement. Therefore, a flexible wire harness clip 1008 is installed on the side of the sealing support plate 1001 near the fixed mounting plate 3. The wire harness connected to the sealing assembly 10 is placed in the flexible wire harness clip 1008. The flexible wire harness clip 1008 is bent at one end in the extension direction of the sealing cylinder 1005. When the sealing cylinder 1005 is extended, the wire harness of the heat sealing knife 1004 and the cutting cylinder 1007 moves forward, so that the bent part of the flexible wire harness clip 1008 is straightened after following the movement of the wire harness. That is, when the heat sealing knife 1004 contacts, the bent part of the flexible wire harness clip 1008 is horizontal. When the sealing cylinder 1005 retracts, the bent part of the flexible wire harness clip 1008 bends back to its initial state.

[0053] The fixed support plate 2 is equipped with a feeding conveyor belt 13, a bagging conveyor belt 14, and a discharging conveyor belt 15 sequentially along its length. The feeding conveyor belt 13, the bagging conveyor belt 14, and the discharging conveyor belt 15 are close to each other, which can realize the conveying of wine boxes from the feeding conveyor belt 13 to the bagging conveyor belt 14, and also realize the conveying of wine boxes from the bagging conveyor belt 14 to the discharging conveyor belt 15. At the same time, in order to ensure the stability of the wine boxes during the conveying process, two limiting baffles 20 are provided above the feeding conveyor belt 13, the bagging conveyor belt 14, and the discharging conveyor belt 15. The two limiting baffles 20 are set along the length of the fixed support plate 2, and the width between the two limiting baffles 20 matches the width of the wine box. That is, when the wine box is placed on the conveyor belt, the wine box is located between the two limiting baffles 20 and is in clearance fit with the two limiting baffles 20.

[0054] A feeding photoelectric sensor 16 is installed on one side of the end of the feeding conveyor belt 13. Limiting rods 2101 are symmetrically arranged on both sides above the end of the feeding conveyor belt 13. Several limiting wheels 2102 are fixedly fitted onto the lower part of the limiting rods 2101. The distance between the corresponding limiting wheels 2102 on two limiting rods 2101 corresponds to the width of the wine box, ensuring that the wine box can pass between the two limiting wheels 2102. An annular groove is formed around the outer wall of each limiting wheel 2102, and an annular limiting rubber ring 2103 is engaged within the groove. The outer wall of the engaged limiting rubber ring 2103 slightly protrudes from the outer wall of the limiting wheel 2102. The tops of the two limiting rods 2101 are respectively connected to... The drive gear 2104 has a servo motor connected to one of the drive gears 2104 and auxiliary gears 2105 installed on both sides of the other drive gear 2104. A toothed belt 2106 is wound around the two drive gears 2104 and the two auxiliary gears 2105 and meshes with them. The servo motor drives one of the drive gears 2104 to rotate, and drives the other drive gear 2104 through the auxiliary gears 2105 and the toothed belt 2106, so that the two drive gears 2104 rotate synchronously relative to each other, that is, one drive gear 2104 rotates clockwise and the other drive gear 2104 rotates counterclockwise, which respectively drives the corresponding limit lever 2101 and limit wheel 2102 to rotate accordingly.

[0055] The bagging conveyor belt 14 consists of two symmetrically arranged conveyor belts. The middle position of the bagging conveyor belt 14 corresponds to the bagging mechanism 6. A through hole is opened at the limiting baffle 20 above the middle of the bagging conveyor belt 14. A fixed positioning block 1701 is installed in one of the through holes, and a movable positioning clip 1702 corresponding to the fixed positioning block 1701 is installed in the other through hole. The inner side of the fixed positioning block 1701 is a transition slope near the feeding conveyor belt 13 and a vertical surface near the discharging conveyor belt 15. The vertical surface of the fixed positioning block 1701 protrudes slightly from the inner side of the limiting baffle 20; the movable positioning card 1702 adopts a U-shaped card, and the card slot of the movable positioning card 1702 matches the width of the bagged wine box.

[0056] A lifting mechanism 19 is provided below the middle of the bagging conveyor belt 14. The center of the lifting mechanism 19 is on the same vertical line as the center of the bagging mechanism 6. The lifting mechanism 19 includes a lifting support plate 1901, which is fixed to the lower part of the frame 1. A vertically arranged lifting screw 1902 is installed on the lifting support plate 1901 at a position corresponding to the bagging mechanism 6. The bottom end of the lifting screw 1902 passes through the lifting support plate 1901 and is fitted with a passive synchronous pulley 1904. The lifting support plate 1901... A servo motor is also fixedly installed on 901. The drive end of the servo motor is connected to an active synchronous pulley 1903. The active synchronous pulley 1903 is flush with the passive synchronous pulley 1904, and a synchronous belt is wrapped around both the active and passive synchronous pulleys 1903 and 1904. A lifting block 1905 with a threaded engagement is fitted onto the lifting screw 1902. Vertical lifting guide rails 1906 are symmetrically installed on both sides of the lifting screw 1902. A lifting seat 1906 with a sliding engagement is installed on each lifting guide rail 1906. 07. A connecting rod is installed between the two sides of the two lifting seats 1907. The middle part of the connecting rod is fixedly connected to the surface of the lifting block 1905. A clamping seat 1801 is fixedly connected to the top surface of the lifting seat 1907. The width of both the lifting seat 1907 and the clamping seat 1801 matches the middle gap of the bagging conveyor belt 14. When the lifting seat 1907 is lifted upward, both the lifting seat 1907 and the clamping seat 1801 can pass through the middle gap of the bagging conveyor belt 14. The clamping seat 1801 moves along the conveying direction of the bagging conveyor belt 14. A low-position clamping plate 1802 and a high-position clamping plate 1803 are respectively provided on both sides.

The bottom inner sides of the low-position clamping plate 1802 and the high-position clamping plate 1803 are respectively connected to clamping cylinders 1804, and the two clamping cylinders 1804 are fixed on the clamping seat 1801. When the top surface of the low-position clamping plate 1802 is flush with the surface of the bagged conveyor belt 14, the top surface of the high-position clamping plate 1803 extends out of the surface of the bagged conveyor belt 14.

[0057] The working process of this invention:

[0058] Initially, the bag opening of the roll film 5 extends slightly beyond the bottom of the bag forming component 605 and is opened by the bag forming component 605, so that the bag opening is in the open state. At this time, the film pressing cylinder 902 is in the retracted state, the film pressing movable plate 903 is away from the film pressing fixed plate 901, and the stretching cylinder 807 is also in the retracted state, pulling the roll film 5 taut. At this time, the adjusting slide 802 is located at the lower part of the adjusting guide rail 801.

[0059] The servo motor connected to the lifting screw 1202 starts, driving the lifting support plate 1201 to rise; at the same time, the servo motor connected to the bag-supporting gear 1107 starts, driving the two bag-supporting connecting seats 1104 to move closer together, that is, the two bag-supporting support frames 1108 to close together, so that the four bag-supporting rods 1109 are all at the bottom of the bag-forming component 605. When the lifting support plate 1201 rises to the highest point, it stops. At this time, the four bag-supporting rods 1109 extend into the bag-forming component 605, and each bag-supporting rod 1109 corresponds to a notch 606 of the bag-forming component 605. The clamping cylinder 1111 is started, and the clamping cylinder 1111 drives the clamping connecting seat to move, so that the clamping rod 1110 moves towards the bag-supporting rod 1109, pressing the roll film 5 at the notch 606 onto the bag-supporting rod 1109, thus completing the clamping of the roll film 5.

[0060] After the roll film 5 is clamped, the servo motor connected to the lifting screw 1202 is started, which drives the lifting support plate 1201 to descend, that is, drives the entire bag-supporting mechanism 11 to descend, pulling out the roll film 5. During the process of pulling out the roll film 5, the servo motor connected to the bag-supporting gear 1107 is started, which drives the two bag-supporting connecting seats 1104 to move away from each other, thereby causing the bag-supporting rods 1109 to separate outward, realizing the opening of the roll film 5. When the bag-supporting mechanism 11 descends to the target position, the length of the roll film 5 pulled out matches the height of the wine box to be bagged, and the opening of the roll film 5 opened by the four bag-supporting rods 1109 matches the size of the top surface of the wine box to be bagged.

[0061] After the bag-supporting mechanism 11 descends to the target position, the sealing cylinder 1005 extends, and the two heat-sealing knives 1004 come into contact with each other to begin heat-sealing the roll film 5. After the roll film 5 is heat-sealed, the cutting cylinder 1007 extends, driving the cutting knife 1006 to extend and cut the roll film 5, thus completing the sealing action.

[0062] When the clamping rod 1110 clamps the roll film 5 onto the bag-supporting rod 1109, the pressing cylinder 902 is still in the retracted state, while the control stretching cylinder 807 extends, and the stretching slide 805 moves upward to release the taut roll film 5. At the same time, the servo motor connected to the unloading shaft 4 starts, driving the unloading shaft 4 to rotate and supply the roll film 5, making it easier for the bag-supporting mechanism 11 to pull the roll film 5 down. During this process, the downward movement speed of the bag-supporting mechanism 11 is greater than the unloading speed of the unloading shaft 4, therefore the roll film 5... During the downward pulling process of film 5, the free roller 803 is pulled upward, causing the adjusting slide 802 to move upward. When the bag-supporting mechanism 11 descends to the target position, the film-pressing cylinder 902 extends, causing the film-pressing movable plate 903 to press the roll film 5 tightly onto the film-pressing fixed plate 901, thus fixing the roll film 5 between the film-pressing fixed plate 901 and the bag-supporting mechanism 11, awaiting heat sealing and cutting. After the film-pressing movable plate 903 presses down, the film-releasing shaft 4 continues to release the film, causing excessive roll film 5 at the front of the free roller 803 to... In the relaxed state, the free roller 803 and the adjusting slide 802 slide downwards under gravity, thereby pulling down the relaxed film roll 5 to ensure its straightness. When the free roller 803 slides down to the lowest point of the adjusting guide rail 801, the film feeding shaft 4 stops feeding the film. At this time, the film roll 5 between the film feeding shaft 4 and the film pressing movable block is in a straight state. After the sealing action is completed, the film roll 5 from the film pressing movable plate 903 to the cut point is in a relaxed free state. At this time, the film pressing cylinder 902 retracts, and the stretching cylinder retracts simultaneously. Cylinder 807, the stretching cylinder 807 drives the stretching slide 805 to move down, the stretching roller 806 moves down to tighten the straightened roll film 5, and at the same time the downward-moving stretching roller 806 will pull the roll film 5 on both sides of the stretching roller 806 downward, so that the free roller 803 moves up to return to the initial position, and at the same time, the opening of the roll film 5 at the cut point is pulled back to the position of the bag part 605, that is, the opening of the roll film 5 also returns to the initial position; the above process completes the bag making, and after the bag is made, it is judged whether the wine box is in place.

[0063] During the bagging process described above, the feeding conveyor belt 13 operates, and wine boxes begin to be fed in. Since limit baffles 20 are installed on both sides of the feeding conveyor belt 13, and the spacing between the limit baffles 20 matches the wine box, the wine box is limited during feeding, ensuring that it does not deflect during the feeding process. Two limit wheels 2102 are matched with the wine box, allowing it to pass between the two limit wheels 2102. Simultaneously, the limit rubber rings 2103 fitted on the limit wheels 2102 protrude from the outer wall of the limit wheels 2102, thus blocking the wine box. When the wine box is conveyed by the feeding conveyor belt 13 to the limit wheels 2102, the front of the wine box enters the two limit wheels. Between the position wheels 2102, the servo motor connected to the drive gear 2104 starts, driving the two drive gears 2104 to rotate synchronously relative to each other, that is, driving the limit stop bar 2101, the limit wheel 2102 and the limit rubber ring 2103 to rotate. Since the limit rubber ring 2103 is elastic, the friction between the rotating limit wheel 2102 and the outer wall of the wine box squeezes the limit rubber ring 2103, so that the wine box passes through the limit stop bar 2101. When the feeding photoelectric sensor 16 detects the wine box signal, it stops the rotation of the limit stop bar 2101. The limit rubber ring 2103 protrudes from the outer wall of the limit wheel 2102, and the next wine box is blocked by the limit rubber ring 2103.

[0064] When the feeding photoelectric sensor 16 detects a wine box signal, the bagging conveyor belt 14 starts, and simultaneously the servo motor connected to the lifting screw 1902 starts, driving the lifting seat 1907 to rise to the target position. At the target position, the low-position clamping plate 1802 of the lifting mechanism 19 is slightly lower than or flush with the surface of the bagging conveyor belt 14, while the high-position clamping plate 1803 extends beyond the surface of the bagging conveyor belt 14, and the surface of the clamping seat 1801 is lower than the surface of the bagging conveyor belt 14. After the feeding conveyor belt 13 feeds the wine box onto the bagging conveyor belt 14, the bagging conveyor belt 14 continues to feed the wine box. During the conveying process, the wine box is blocked by the extended high-position clamping plate 1803. When the wine box reaches the high-position clamping plate 1803, the positioning photoelectric sensor 1704 detects a signal. When the control bagging conveyor belt 14 stops, the positioning cylinder 1703 extends, driving the positioning movable card to move towards the wine box. The U-shaped slot of the positioning movable card matches the wine box and clamps the wine box against the fixed positioning block 1701, completing the positioning of the wine box. After positioning, the wine box is located directly below the bag forming mechanism 6 and directly above the lifting seat 1907. After the wine box is positioned, the lifting seat 1907 rises, driving the clamping seat 1801 to rise. When the surface of the clamping seat 1801 is in close contact with the bottom surface of the wine box, the two clamping cylinders 1804 work, driving the low clamping plate 1802 and the high clamping plate 1803 to move towards the outer wall of the wine box, realizing the clamping of the wine box. After the clamping work is completed, the positioning cylinder 1703 retracts. At this time, it is determined whether the bag making is completed.

[0065] When the wine box clamping and bag making processes are completed, the bag is positioned directly above the wine box. Then, the bag-supporting mechanism 11 is lowered and the lifting mechanism 19 is raised to place the completed bag over the wine box. After bagging, the clamping cylinder 1111 moves the clamping seat, causing the clamping rod 1110 to move away from the bag-supporting rod 1109, thus releasing the film roll 5. After release, the entire bag-supporting mechanism 11 continues to lower until the bag-supporting rod 1109 is removed from below the bag. Then, the servo motor connected to the bag-supporting gear 1107 starts, controlling the two bag-supporting support frames 1108 to move away from each other, causing the bag-supporting rod 1109 to move away from the bag. Finally, the bag-supporting mechanism 11... The lifting mechanism 19 lowers to allow for the next bag-making operation. Simultaneously, the lifting mechanism 19 descends until the surface of the clamping seat 1801 is flush with the surface of the bagging conveyor belt 14. At this point, the clamping cylinder 1804 operates, releasing the low-position clamping plate 1802 and the high-position clamping plate 1803. The lifting mechanism 19 then continues to descend until the top surface of the high-position clamping plate 1803 is lower than the surface of the bagging conveyor belt 14, at which point it stops. The wine box is then placed on the bagging conveyor belt 14. The bagging conveyor belt 14 and the discharge conveyor belt 15 are then started to transport the wine box through the bagging conveyor belt 14 to the discharge conveyor belt 15, completing the discharge. The lifting mechanism 19 then performs the next wine box clamping operation.

[0066] By equipping a control cabinet and cyclically operating the above-mentioned work process, automated bagging of wine boxes can be achieved.

Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
