Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and more specifically to an M-bag vertical bagging machine. Background Technology

[0002] Currently, many food packaging bags used are M-type bags (referred to as M bags) with M-shaped folds on the sides. M bags are at least divided into the following two types, as shown in the attached diagram. Figure 1 As shown, the first type of M-bag is a packaging bag with M-shaped creases. This means the bag is formed by folding the packaging film, sealing it longitudinally, and then sealing the bottom. The two sides of the bag have creases. (See attached image.) Figure 2 As shown, the second type of M bag is formed by two sealing edges and a crease. Specifically, it is formed by sealing the front film, the back film, and the two side films together. The two side films are folded inward to form a crease, and the two ends of the side films are sealed together with the front film and the back film to form two sealing edges.

[0003] For example, the utility model patent with authorization announcement number CN219154893U, authorization announcement date June 9, 2023, entitled "Vertical Bag-Type Bag-Placing Machine," describes a bag-placing machine whose working principle is as follows: a bag-retrieving device takes out packaging bags one by one from a bag magazine; then, a bag-placing device opens the bag opening and places the opened bag onto the bag-supporting device of a turntable bag-supporting device; the turntable bag-supporting device then rotates, driving the packaging bag into the filling hopper for material filling; after filling, the bag is sealed. This vertical bag-placing machine is only suitable for bagging the first type of M-bag and not for bagging the second type of M-bag.

[0004] The bag stretcher in the aforementioned vertical bagging machine extends into the M-bag to open it. After material filling, the M-bag separates from the stretcher, and the corner-inserting device forms the corners of the bag opening (M-type sealing) before conveying it to the heat-sealing mechanism for sealing. Because existing bagging machines use a stretcher to open the M-bag, this damages the bag's creases. When using a bagging machine to package materials with M-bags, the processing precision of the M-bag itself is required to be high. The thickness on both sides of the M-bag must be consistent, and the inward creases on both sides must be highly aligned. If the M-bag's precision is poor, the corner-inserting device of the vertical bagging machine will have a poor forming effect when forming the corners of the filled M-bag opening, affecting the overall sealing effect of the M-bag. Utility Model Content

[0005] To overcome the defects and shortcomings of the existing technology, this utility model provides a vertical bagging machine for M-bags. The purpose of this invention is to improve the structure of the existing vertical bagging machine so that it can be used for both the first and second types of M-bags, and to reduce the processing precision requirements for M-bags. It also eliminates the corner insertion device in the existing bagging machine, thereby reducing equipment costs. This utility model includes a bag storage device, a bag picking device, a bag-packing device, a turntable bag-supporting device, a hopper, a bag-clamping and feeding device, and a sealing device. The turntable bag-supporting device includes a bag-supporting turntable and a driving mechanism for rotating the turntable. At least two sets of bag-clamping and supporting mechanisms are provided on the turntable. Each set of bag-clamping and supporting mechanisms includes a pair of oppositely arranged bag-clamping and supporting components, and the distance between these components is adjustable. Each bag-clamping and supporting component includes an openable upper bag-clamping opening and a lower bag-clamping opening, which can be relatively close to or far apart. This utility model improves the structure of the turntable bag-supporting device in the vertical bag-packing machine by replacing the bag support with a double-clamp bag mouth clamping and supporting mechanism, realizing the opening and closing of the M bag mouth and the M-shaped sealing formation. This can reduce the processing accuracy requirements of the M bag and also eliminate the corner insertion device in the existing bag-packing machine, thereby reducing the equipment cost of the bag-packing machine.

The clamping push plate moves towards the upper bag clamping assembly and the lower bag clamping assembly under the action of an external pushing force, pushing the upper movable bag clamp and the lower movable bag clamp to rotate around their hinge axis, opening the upper bag clamping opening and the lower bag clamping opening. The clamping push plate is reset by the action of the tension spring connected to it, and the upper movable bag clamp and the lower movable bag clamp are reset by the action of the tension spring connected to them, closing the upper bag clamping opening and the lower bag clamping opening.

The front end of the corner insert piece extends through the bag clamping and supporting bag mounting seat between the upper fixed bag clamp and the lower fixed bag clamp. The sliding seat is provided with a rotatable roller. When the roller on the sliding seat is subjected to external force, the sliding seat slides along the slide rail, causing the corner insert piece to fold the side of the M bag inward toward the bag opening. The sliding seat is reset under the action of the tension spring connected to it.

[0012] More preferably, the frame on both sides above the lowest bag clamping and supporting mechanism is provided with an insertion angle drive assembly, which includes a cylinder and an inclined platform, and the inclined surface of the inclined platform cooperates with the rollers on the sliding seat.

[0013] More preferably, a first rack is installed on the upper bag clamping plate, a second rack is installed on the lower bag clamping plate, and a gear is rotatably mounted on the bag clamping support mounting seat, with the gear located between the first rack and the second rack, and both the first rack and the second rack meshing with the gear.

[0019] More preferably, the bag clamping and feeding device includes a bag clamping opening mechanism and a translation mechanism. The bag clamping opening mechanism is mounted on the translation mechanism, which drives the bag clamping opening mechanism to reciprocate from below the lowest bag clamping and supporting mechanism to below the sealing device. The bag clamping opening mechanism includes a first bag clamping arm, a second bag clamping arm, and a bag clamping drive assembly that drives the first bag clamping arm and the second bag clamping arm to translate and move relatively closer and further apart. The first bag clamping arm is provided with a first lifting cylinder extending vertically, and the second bag clamping arm is provided with a second lifting cylinder extending vertically. Both the first lifting cylinder and the second lifting cylinder are equipped with a clamping plate.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. This utility model improves the structure of the existing vertical bagging machine by replacing the existing bag support structure with a rotary bag support device with a double clamping structure. The left bag clamping and supporting component is used to clamp the two sealing edges on one side of the M bag, and the right bag clamping and supporting component is used to clamp the two sealing edges on the other side of the M bag. When the M bag is fed in horizontally, the upper bag clamping component is used to clamp the upper sealing edge of the M bag, and the lower bag clamping component is used to clamp the lower sealing edge of the M bag. The upper and lower bag clamping openings of the left and right bag clamping and supporting components open simultaneously to receive and clamp the M bag being conveyed. When the upper and lower bag clamping components move away from each other, the bag opening of the M bag is opened. This invention utilizes the bag structure of the M bag for clamping and supporting the bag. Compared with the existing bag support structure, it has lower requirements for the processing precision of the M bag. When closing the M bag, the upper bag clamping assembly and the lower bag clamping assembly approach each other to close the bag opening. This eliminates the need for the corner insertion device structure in the existing bagging machine, thereby reducing the equipment cost of the bagging machine.

[0021] 2. The upper and lower movable bag clamps of this utility model are bent and, in conjunction with the rollers at their ends, can better cooperate with the opening push plate of the opening assembly to achieve the opening action. Simultaneously, since the upper and lower bag clamp assemblies need to be relatively close and relatively far apart, the structure of the opening assembly of this utility model is not affected by the relative movement of the upper and lower bag clamp assemblies, and can open normally in both cases. When the upper and lower bag clamp assemblies move relative to each other, under the action of the rollers, the upper and lower movable bag clamps can move along the opening push plate without changing the position of the opening push plate. This eliminates the need to change the pushing stroke of the opening drive mechanism that pushes the opening push plate, keeping the opening action of the opening drive mechanism constant, thereby simplifying the control and structural design of the opening drive mechanism.

[0022] 3. The opening clamp assembly of this utility model utilizes a first connecting rod and a second connecting rod to assemble the opening clamp push plate and the bag support mounting base together, forming a parallelogram-shaped linkage structure. When the opening clamp push plate moves towards the upper and lower movable bag clamps, it will move relative to the upper and lower movable bag clamps. Only a pushing force along the length of the opening clamp push plate is needed to push the opening clamp push plate against the upper and lower movable bag clamps, thereby opening the clamps. Even if the upper and lower bag clamp assemblies move relative to each other, it does not affect the pushing stroke and method of the external force on the opening clamp push plate. This simplifies the structural form of the opening clamp drive assembly. At the same time, when a cylinder is used as the opening clamp drive assembly, the force acting on the upper and lower movable bag clamps is made gentler through the force conversion of the opening clamp assembly, avoiding damage to the upper and lower movable bag clamps. The opening push plate is reset by the action of a tension spring. Therefore, only an external pushing force needs to be applied to the opening push plate to open the clamp. The closing of the bag opening is achieved by the tension spring force, which simplifies the drive structure.

[0023] 4. This utility model achieves relative motion transmission between the upper bag clamping assembly and the lower bag clamping assembly through racks mounted on the upper and lower bag clamping plates and gears rotatably mounted between the racks. The structure is simple and the operation is stable. Only a thrust needs to be applied to the rack to achieve the relative movement of the upper bag clamping assembly and the lower bag clamping assembly away from each other.

[0024] 5. The left and right clamping bag support components of this utility model can adjust the distance between them through the spacing adjustment component, so as to adapt to M bags of different widths. When the width of the M bag changes, the spacing adjustment component can be used to adapt to the width change of the M bag.

[0025] 6. This utility model has a corner insert assembly on the bag clamping and supporting mounting base. After the material is filled into the M bag, an external force can be used to push the sliding seat in the corner insert assembly to make it move horizontally, causing the corner insert piece to fold the side of the M bag inward, thus realizing the M-shaped folding and forming of the bag opening. This further improves the M-shaped forming effect of the M bag sealing. Compared with the upper bag clamping assembly and the lower bag clamping assembly being close together, the addition of the corner insert assembly further improves the sealing and forming effect of the M bag, ensuring that the M bag is sealed neatly. It can also eliminate the complex corner insert device in the existing bagging machine, reducing the cost of the bagging machine equipment.

[0026] 7. The corner insertion drive assembly of this utility model consists of a cylinder and a ramp. By utilizing the ramp's inclined surface and the rollers on the sliding seat of the corner insertion assembly, the timing and force of the corner insertion can be controlled by the slope of the ramp. This avoids damage to the M bag caused by fast, stiff, and forceful movements. At the same time, the ramp design also avoids interference between the corner insertion drive assembly and other components, which is beneficial for assembly.

[0027] 8. This utility model integrates the clamping drive component and the bag-supporting drive component on the bag-supporting turntable mounting base, resulting in a high degree of structural integration and preventing interference between the drive component and other mechanisms of the bagging machine. Furthermore, for the bag clamping and supporting mechanism located at the highest position, its function is to receive bag M. At this position, only the clamp needs to be opened to grip the bag M. However, for the bag clamping and supporting mechanism at the lowest position, the bag M needs to be opened. After material filling, the bag M also needs to be released. Since the actions of opening the bag M and releasing the bag clamp are not simultaneous, a bag-supporting drive component and a clamping drive component are provided to separately realize the bag-supporting action and the clamping action.

[0028] 9. The bag clamping and feeding device of this utility model is equipped with a lifting cylinder. By lifting the lifting cylinder, the clamping plate can be extended, which can avoid interference with other components or space, and is more conducive to the structural layout. The lifting cylinder can also drive the clamping plate to lift, which is conducive to the M bag that has been filled with materials and formed M bag leaving the bag clamping and supporting mechanism better.

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1 As a preferred embodiment of this utility model, please refer to the appendix to the specification. Figure 1 As shown, this embodiment discloses an M-bag vertical bagging machine, including a bag storage device 1, a bag picking device 200, a bagging device 300, a turntable bag supporting device 400, a feeding hopper 500, a bag clamping and feeding device 600, and a sealing device 700; the turntable bag supporting device 400 includes a bag supporting turntable 1 and a driving mechanism 2 for driving the bag supporting turntable 1 to rotate. At least two sets of bag clamping and supporting mechanisms 3 are provided on the bag supporting turntable 1, one set of bag clamping and supporting mechanisms 3 is located at the highest position 4, and the other set of bag clamping and supporting mechanisms 3 is located at the lowest position 5. The two sets of bag clamping and supporting mechanisms 3 are driven alternately by the bag supporting turntable 1; the central axis of the bag supporting turntable 1 forms a 45° angle with the horizontal line; when the bag clamping and supporting mechanism 3 is located at the highest position 4, it is in a vertical state, and when the bag clamping and supporting mechanism 3 is located at the lowest position 5, it is in a horizontal state; Each bag clamping and supporting mechanism 3 includes a pair of bag clamping and supporting components arranged opposite to each other, and the distance between the pair of bag clamping and supporting components is adjustable; the bag clamping and supporting components include an upper bag clamping opening 15 and a lower bag clamping opening 18 that can be opened and closed, and the upper bag clamping opening 15 and the lower bag clamping opening 18 can be relatively close to each other and far apart; when the upper bag clamping opening 15 and the lower bag clamping opening 18 are relatively far apart, the bag opening of bag M is opened.

[0032] The bag-retrieving device 200 is configured to retrieve M bags one by one from the bag storage device 1, and the bag-feeding device 300 is configured to open part of the bag opening of the M bags retrieved by the bag-retrieving device 200 and feed the upper and lower folded edges of the M bags into the upper clamping bag opening 15 and the lower clamping bag opening 18. In this embodiment, the feeding hopper 500 is mounted above the bag clamping and supporting mechanism 3 at the lowest position 5, and the feeding hopper 500 is configured to fill materials into the M bags that are clamped and opened by the bag clamping and supporting mechanism 3 at the lowest position 5.

[0033] In this embodiment, the existing vertical bagging machine is structurally improved by replacing the existing bag support structure with a rotary bag support device 400 with a double-clamp structure. The left bag clamping and supporting component 6 is used to clamp the two sealing edges on one side of the M bag, and the right bag clamping and supporting component 7 is used to clamp the two sealing edges on the other side of the M bag. When the M bag is fed in horizontally, the upper bag clamping opening 15 is used to clamp the upper sealing edge of the M bag, and the lower bag clamping opening 18 is used to clamp the lower sealing edge of the M bag. The upper bag clamping opening 15 and the lower bag clamping opening 18 of the left bag clamping and supporting component 6 and the right bag clamping and supporting component 7 open at the same time to receive and clamp the M bag being conveyed. The upper bag clamping opening 15 and the lower bag clamping opening 18 move away from each other, thus opening the bag opening of the M bag. This utility model utilizes the bag structure of the M bag for clamping and supporting the bag. Compared with the existing bag support structure, it has lower requirements for the processing precision of the M bag. When closing the M bag, the upper clamping bag opening 15 and the lower clamping bag opening 18 come close to each other to achieve the closure of the M bag opening. This eliminates the need for the corner insertion device structure in the existing bagging machine, thereby reducing the equipment cost of the bagging machine.

[0034] Example 2 As another preferred embodiment of this utility model, this embodiment is a further detailed supplement and explanation of the technical solution of this utility model based on the above-described embodiment 1. In this embodiment, refer to the appendix to the specification. Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 and attached Figure 11 As shown, this embodiment is a further supplement and explanation of the specific implementation structure of the turntable bag support device 400 described above.

[0035] The bag clamping and supporting assembly includes a bag clamping and supporting mounting base 8, an upper bag clamping plate 9, a lower bag clamping plate 10, an upper bag clamping assembly 11, a lower bag clamping assembly 12, and an opening clamping assembly. The upper bag clamping plate 9 and the lower bag clamping plate 10 are slidably mounted on the bag clamping and supporting mounting base 8. The upper bag clamping assembly 11 is mounted on the upper bag clamping plate 9, and the lower bag clamping assembly 12 is mounted on the lower bag clamping plate 10. The upper bag clamping assembly 11 and the lower bag clamping assembly 12 are arranged opposite to each other, and the upper bag clamping assembly 11 and the lower bag clamping assembly 12 can move closer to each other and further away from each other. The upper bag clamping assembly 11 includes an upper fixed bag clamp 13 and an upper movable bag clamp 14. The upper fixed bag clamp 13 is fixed on the upper bag clamping plate 9. The upper movable bag clamp 14 is arranged opposite to the upper fixed bag clamp 13, located above the upper fixed bag clamp 13, and cooperates with the upper fixed bag clamp 13 to form the upper bag opening 15; the upper movable bag clamp 14 is hinged to the upper bag clamping plate 9, and the end of the upper movable bag clamp 14 away from the upper bag opening 15 is bent downward and a roller that cooperates with the opening clamping assembly is provided at its end; the upper movable bag clamp 14 is reset and closed with the upper fixed bag clamp 13 by a tension spring; The lower bag clamp assembly 12 includes a lower fixed bag clamp 16 and a lower movable bag clamp 17. The lower fixed bag clamp 16 is fixed on the lower clamping plate 10. The lower movable bag clamp 17 is arranged opposite to the lower fixed bag clamp 16, located below the lower fixed bag clamp 16, and cooperates with the lower fixed bag clamp 16 to form a lower bag opening 18. The lower movable bag clamp 17 is hinged to the lower clamping plate 10. The end of the lower movable bag clamp 17 away from the lower bag opening 18 is bent upward and a roller that cooperates with the opening clamp assembly is provided at its end. The lower movable bag clamp 17 is reset and closed with the lower fixed bag clamp 16 by a tension spring.

[0036] In this embodiment, the upper movable bag clamp 14 and the lower movable bag clamp 17 are bent and, in conjunction with the rollers at their ends, can better cooperate with the opening push plate 19 of the opening clamp assembly to achieve the opening action. Meanwhile, since the upper bag clamp assembly 11 and the lower bag clamp assembly 12 need to be relatively close and relatively far apart, the structure of the opening clamp assembly provided in this invention is not affected by the relative movement of the upper bag clamp assembly 11 and the lower bag clamp assembly 12, and both can open normally. When the upper bag clamp assembly 11 and the lower bag clamp assembly 12 move relative to each other, the upper movable bag clamp 14 and the lower movable bag clamp 17 can move along the opening push plate 19 under the action of the rollers, without changing the position of the opening push plate 19. This eliminates the need to change the pushing stroke of the opening drive mechanism 2 that pushes the opening push plate 19, keeping the opening action of the opening drive mechanism 2 unchanged, thereby simplifying the control and structural settings of the opening drive mechanism 2.

[0037] The clamping assembly utilizes a first connecting rod 20 and a second connecting rod 21 to assemble the clamping push plate 19 with the bag support mounting base 8, forming a parallelogram-shaped linkage structure. When the clamping push plate 19 moves towards the upper movable bag clamp 14 and the lower movable bag clamp 17, it will move relative to the upper movable bag clamp 14 and the lower movable bag clamp 17. Only a thrust along the length of the clamping push plate 19 is needed to push the clamping push plate 19 against the upper movable bag clamp 14 and the lower movable bag clamp 17, thereby opening the clamp. Even if the upper bag clamp assembly 11 and the lower bag clamp assembly 12 move relative to each other, it will not affect the stroke and method of the external force pushing the clamping push plate 19. This simplifies the structure of the clamping drive assembly. At the same time, when a cylinder is used as the clamping drive assembly, the force acting on the upper movable bag clamp 14 and the lower movable bag clamp 17 is made gentler through the thrust conversion of the clamping assembly, avoiding damage to the upper movable bag clamp 14 and the lower movable bag clamp 17. The opening push plate 19 is reset by the action of a tension spring. Therefore, only an external pushing force needs to be applied to the opening push plate 19 to open the clamp. The closing of the bag opening is achieved by the tension spring force, which simplifies the drive structure.

(Refer to the appendix of the specification.) Figure 12 Appendix Figure 13 and attached Figure 14 As shown, the bag clamping and supporting mounting base 8 has an insert corner assembly 30 on the opposite side of the mounting side of the upper bag clamping plate 9 and the lower bag clamping plate 10. The insert corner assembly is slidably mounted on the bag clamping and supporting mounting base 8 via a slide rail. The insert corner assembly 30 includes a sliding seat 31 and an insert corner piece 32. The front end of the insert corner piece 32 extends through the bag clamping and supporting mounting base 8 between the upper fixed bag clamp 13 and the lower fixed bag clamp 16. The sliding seat 31 is provided with a rotatable roller. When the roller on the sliding seat 31 is subjected to external force, the sliding seat 31 slides along the slide rail, causing the insert corner piece 32 to fold the side of the M bag inward toward the bag opening. The sliding seat 31 is reset under the action of the tension spring connected to it.

[0039] In this embodiment, a corner insert assembly 30 is provided on the bag clamping and supporting mounting base 8. After the material is filled into the M bag, an external force can be used to push the sliding seat 31 in the corner insert assembly 30 to make it move horizontally, thereby driving the corner insert piece 32 to fold the side of the M bag inward, realizing the M-shaped folding and forming of the bag opening. This further improves the M-shaped forming effect of sealing the M bag. Compared with the approach of the upper bag clamping assembly 11 and the lower bag clamping assembly 12 being close together, the addition of the corner insert assembly 30 further improves the sealing and forming effect of the M bag, ensuring that the M bag is neatly sealed. It can also eliminate the complex corner insert device in the existing bagging machine, reducing the cost of the bagging machine equipment.

[0040] Furthermore, on the frames above the bag clamping and supporting mechanism 3 at the lowest position 5, corner insertion drive assemblies (not shown in the figure) are installed on both sides. The corner insertion drive assembly includes a cylinder and a ramp, and the inclined surface of the ramp engages with the rollers on the sliding seat 31. The corner insertion drive assembly consists of a cylinder and a ramp. By utilizing the ramp's inclined surface to engage with the rollers on the sliding seat 31 of the corner insertion assembly 30, the timing and force of the corner insertion can be controlled by the slope of the ramp. This avoids damage to the M-bag caused by rapid, harsh, and forceful movements. At the same time, the ramp design also prevents interference between the corner insertion drive assembly and other components, which is beneficial for assembly.

[0041] Example 4 As another preferred embodiment of this utility model, this embodiment further supplements and elaborates on the technical solution of this utility model based on the above-described embodiment 2 or embodiment 3. In this embodiment, a first rack 22 is installed on the upper bag clamping plate 9, a second rack 23 is installed on the lower bag clamping plate 10, and a gear 24 is rotatably mounted on the bag clamping support mounting seat 8, with the gear 24 located between the first rack 22 and the second rack 23, and both the first rack 22 and the second rack 23 meshing with the gear 24. In this embodiment, the relative motion transmission between the upper bag clamping assembly 11 and the lower bag clamping assembly 12 is achieved by the racks mounted on the upper bag clamping plate 9 and the lower bag clamping plate 10 and the gear 24 rotatably mounted between the racks. The structure is simple and the operation is stable. Only a thrust needs to be applied to the racks to achieve the relative separation movement of the upper bag clamping assembly 11 and the lower bag clamping assembly 12.

[0042] Example 5 As another preferred embodiment of this utility model, this embodiment further supplements and elaborates on the technical solution of this utility model based on the above-described embodiments 1, 2, 3, or 4. In this embodiment, the bag-supporting turntable 1 is provided with a support mounting base 29 for assembling the bag-clamping and bag-supporting mechanism 3. A slide rail is provided on the support mounting base 29, and the left bag-clamping and bag-supporting assembly 6 and the right bag-clamping and bag-supporting assembly 7 are slidably assembled on the support mounting base 29. A spacing adjustment assembly 25 is also installed on the support mounting base 29, and the spacing between the left and right bag-clamping and bag-supporting assemblies is adjusted by the spacing adjustment assembly 25 to adapt to bags of different widths. When the width of the bag changes, the spacing adjustment assembly 25 can be used to adapt to the change in the width of the bag.

[0043] As an example, the spacing adjustment assembly 25 includes a first lead screw seat 26, a second lead screw seat 27, and a bidirectional threaded lead screw 28. The bidirectional threaded lead screw 28 is rotatably mounted in the first lead screw seat 26 and the second lead screw seat 27. The left bag clamping and supporting assembly 6 and the right bag clamping and supporting assembly 7 are respectively threaded onto the positive and negative thread sections of the bidirectional threaded lead screw 28.

[0044] Example 6 As another preferred embodiment of this utility model, this embodiment further supplements and elaborates on the technical solution of this utility model based on the above-mentioned embodiments 1, 2, 3, 4 or 5. In this embodiment, the turntable bag-supporting device 400 further includes a bag-supporting turntable mounting base 33. The bag-supporting turntable 1 is mounted on the bag-supporting turntable mounting base 33 via a hollow rotating table 34. The driving mechanism 2 is mounted on the bag-supporting turntable mounting base 33 and is connected to the hollow rotating table 34 for transmission, driving the bag-supporting turntable 1 to rotate. The bag-supporting turntable mounting base 33 is provided with a first opening clamping drive assembly 35 acting on the opening clamping push plate 19 of the highest position 4 bag-supporting mechanism 3, a second opening clamping drive assembly 36 acting on the opening clamping push plate 19 of the lowest position 5 bag-supporting mechanism 3, and a lower bag-supporting drive assembly 37 acting on the upper bag clamping plate 9 and the lower bag clamping plate 10 of the lowest position 5 bag-supporting mechanism 3 to drive the upper bag clamping assembly 11 and the lower bag clamping assembly 12 away from each other.

[0045] In this embodiment, the clamping drive assembly and the bag-supporting drive assembly are integrated on the bag-supporting turntable mounting base 33, resulting in a high degree of structural integration and preventing interference between the drive assembly and other mechanisms of the bagging machine. Furthermore, the bag-clamping and supporting mechanism 3 at the highest position 4 is used to receive bags M; at this position, only clamping is required to grip the bags. However, the bag-clamping and supporting mechanism 3 at the lowest position 5 needs to open the bags M. After material filling, the bags M also need to be released. Since the actions of opening the bags M and releasing the bag clamps are not simultaneous, a bag-supporting drive assembly and a clamping drive assembly are provided to separately realize the bag-supporting and clamping actions.

[0046] Furthermore, as a preferred example, this embodiment also includes an upper bag support drive assembly 38, which acts on the upper bag clamping plate 9 and the lower bag clamping plate 10 of the highest position 4 bag clamping and supporting mechanism 3 to drive the upper bag clamping assembly 11 and the lower bag clamping assembly 12 away from each other.

[0047] As an example, the clamp opening drive assembly and the bag opening drive assembly can be implemented using a structure where a cylinder connects to the push plate, or a structure where a servo motor assembly connects to the push plate via a crank-connecting rod transmission assembly. Using a servo motor assembly as the clamp opening drive assembly and / or the bag opening drive assembly can smooth the push plate movement and avoid harsh contact forces that could lead to severe wear on components.

[0048] Example 7 As another preferred embodiment of this utility model, this embodiment further supplements and elaborates on the technical solution of this utility model based on the above-described embodiments 1, 2, 3, 4, 5, or 6. In this embodiment, refer to the appendix to the specification.Figure 15 As shown, the bag clamping and feeding device 600 includes a bag clamping mechanism 40 and a translation mechanism 39. The bag clamping mechanism 40 is mounted on the translation mechanism 39. The translation mechanism 39 drives the bag clamping mechanism 40 to reciprocate from below the lowest position 5 bag clamping and supporting mechanism 3 to below the sealing device 700. The bag clamping mechanism 40 includes a first bag clamping arm 41, a second bag clamping arm 42, and a bag clamping drive assembly 43 that drives the first bag clamping arm 41 and the second bag clamping arm 42 to move closer and further apart. The first bag clamping arm 41 is provided with a vertically extending first lifting cylinder 44, and the second bag clamping arm 42 is provided with a vertically extending second lifting cylinder 45. Both the first lifting cylinder 44 and the second lifting cylinder 45 are equipped with a clamping plate 46.

[0049] The bag clamping and feeding device 600 is equipped with a lifting cylinder. By raising and lowering the lifting cylinder, the clamping plate 46 extends, which can avoid interference with other components or space, and is more conducive to the structural layout. The lifting cylinder can also drive the clamping plate 46 to rise and fall, which is conducive to the M bag that has been filled with materials and formed M bag leaving the bag clamping and supporting mechanism 3 more easily.
