Description

Technical Field

[0001] This utility model relates to the field of paper bag stacking and packaging, and in particular to a lifting and stacking discharge device for paper bag stacking and sealing equipment. Background Technology

[0002] With the deepening penetration of green consumption concepts and the continuous upgrading of brand communication needs, biodegradable paper packaging containers, which combine eco-friendly characteristics with surface printing technology, have become the core carrier of modern commodity circulation and marketing promotion systems. In current industrial production processes, after automated bag-making equipment completes the bag forming process, manual intervention is still required to perform multiple post-processing steps. Operators need to constantly pick up and stack the bags at the exit of the automated bag-making equipment, which is prone to material collapse due to operator errors, and manual stacking is inefficient. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by providing a lifting and stacking discharge device for an automatic paper bag stacking and sealing equipment, which improves production efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lifting and stacking discharge device for a paper bag stacking and sealing equipment, comprising a frame, a support assembly, a lifting and stacking mechanism, and a lifting and material handling mechanism. The frame has a vertically arranged stacking channel, which is provided with an inlet station, a stacking station, and an outlet station from bottom to top. The inlet station is connected to a bag-making device. The support assembly includes telescopic blocks, which are respectively arranged opposite to each other on both sides of the stacking station. The telescopic blocks can move towards each other to form a material support surface. The lifting and stacking mechanism includes a... A secondary lifting stacking platform and a lifting drive assembly are included. The lifting drive assembly drives the primary lifting stacking platform to move up and down between the feeding station and the stacking station. The primary lifting stacking platform has clearance space for avoiding telescopic support blocks. A lifting and unloading mechanism is also included, comprising a secondary lifting discharge platform, a horizontal drive assembly, and a vertical drive assembly. The secondary lifting discharge platform is positioned above the primary lifting stacking platform. The horizontal drive assembly drives the secondary lifting discharge platform to extend into or out of the vertical stacking channel in the left and right directions. The vertical drive assembly drives the secondary lifting discharge platform to reciprocate in the vertical direction.

[0005] This utility model's one-stage lifting stacking platform receives materials at the feeding station. The lifting drive component drives the one-stage lifting stacking platform to deliver the materials to the lifting stacking mechanism. During the lifting process, the first telescopic support block retracts to allow materials to enter. Subsequently, the one-stage lifting stacking platform moves up to stack the materials at the stacking station. The telescopic support blocks set in opposite directions extend to support the materials. At the same time, the one-stage lifting stacking platform returns to the feeding station. Through multiple back-and-forth movements, continuous vertical stacking of materials is achieved. When the number of reciprocating movements of the one-stage lifting stacking platform reaches a preset value, the two-stage lifting discharge platform moves to the stacking station and transfers the materials stacked to the predetermined value to the discharge station, realizing automatic stacking, improving stacking efficiency, and ensuring the consistency of the quantity of materials in a single stack.

[0006] Preferably, the vertical stacking channel also includes a waiting station located between the stacking station and the unloading station. The waiting station is also equipped with a support component. The lifting drive component has a material stacking mode and an overall lifting mode. In the material stacking mode, the lifting drive component drives a single-stage lifting stacking platform from the feeding station to the stacking station. In the overall lifting mode, the lifting drive component drives a single-stage lifting stacking platform from the feeding station to the waiting station. The vertical drive component drives a secondary lifting unloading platform to move up and down reciprocally between the waiting station and the unloading station. The waiting station allows the lifting stacking mechanism to immediately perform the next batch of operations after completing the current stack, eliminating waiting time between processes and improving efficiency.

[0007] Preferably, the secondary lifting discharge platform has two sets, arranged facing each other on the left and right sides of the vertical stacking channel. Each set of the secondary lifting discharge platform is independently connected to a horizontal drive component and a vertical drive component. The force distribution of the secondary lifting discharge platforms arranged on both sides is uniform, reducing the risk of deformation.

[0008] Preferably, the telescopic support block is connected to a linear drive mechanism that drives its back-and-forth linear movement, or the telescopic support block is oscillatingly mounted on the frame.

[0009] Furthermore, when the telescopic support block is configured to swing, one end of the telescopic support block is hinged to a mounting base on the frame, and the other end is provided with a protruding post that can slide along the guide groove of the mounting base. A return spring is provided between the mounting base and the support block. The elastic force of the return spring restores the support block to its initial position, achieving rapid retraction and extension while avoiding rigid impact.

[0010] Preferably, the discharge station is equipped with a limiting top plate, the lower surface of which forms a height-adjustable pressing space with the upper surface of the secondary lifting discharge platform. The compaction space formed by the limiting top plate and the secondary lifting discharge platform applies controllable pressure to the paper bag stack, making the material compact and facilitating subsequent packaging processes. In addition, the height adjustment can accommodate more packaging needs.

[0011] Preferably, a feeding conveyor belt connects the feeding station and the bag-making device, and feeding pushers are spaced apart on the conveying surface of the feeding conveyor belt. This integrates bag making and stacking collection, improving collection efficiency.

[0012] Furthermore, a connecting mechanism is provided between the feeding conveyor belt and the one-time lifting stacking platform. This connecting mechanism includes a transition plate and a connecting push plate. The transition plate connects the feeding station and the feeding conveyor belt, and has a pushing clearance for the feeding push plate to pass through. The connecting push plate is offset from the feeding push plate, and is drively connected to its lateral movement clearance drive mechanism and its forward and backward movement pushing drive mechanism. This connecting mechanism ensures stable material entry into the feeding station, and the offset between the connecting push plate and the feeding push plate prevents interference between them.

[0013] Preferably, the feeding station is also equipped with relatively movable correction plates, which are located on the left and right sides of the single-lift stacking platform. The direction of movement of the correction plates is perpendicular to the extension direction of the vertical stacking channel. The opposing movement of the left and right correction plates can correct the feeding posture of the material and ensure the quality of subsequent packaging.

[0014] Preferably, the frame is equipped with a left guide plate and a right guide plate, and the vertical stacking channel is located between the left and right guide plates. The left and right guide plates are adjustable left and right on the frame. This prevents materials from tilting when moving and stacking within the vertical stacking channel, further ensuring the quality of subsequent packaging. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The X-axis is the horizontal direction, i.e., the left-right direction; the Y-axis is the vertical direction, i.e., the front-back direction; and the Z-axis is the vertical direction, i.e., the up-down direction.

[0021] The paper bag stacking and sealing equipment includes a lifting and stacking discharge device, a support assembly 2, a lifting and stacking mechanism, and a lifting and picking mechanism. The frame 1 has a vertical stacking channel 11 arranged in the vertical direction. The front and rear side plates inside the frame 1 form the vertical stacking channel 11 for vertical stacking of materials. In order to ensure that the materials are stacked neatly in the vertical direction, the frame 1 is provided with a left guide plate 91 and a right guide plate 92. The vertical stacking channel 11 is located between the left guide plate 91 and the right guide plate 92. The left guide plate 91 and the right guide plate 92 are respectively adjusted left and right on the frame 1. The top of the frame 1 has a mounting beam. The left guide plate 91 and the right guide plate 92 are respectively connected to the mounting beam through adjusting connecting brackets. The adjusting connecting brackets have horizontally arranged guide grooves 221. The left guide plate 91 and the right guide plate 92 can be adjusted left and right by tightening bolts. Other adjustment methods of existing technology can also be used. The vertical stacking channel 11 is provided with a feeding station 111, a stacking station 112, and a discharging station 113 from bottom to top. The supporting component 2 includes telescopic support blocks 21, which are respectively arranged opposite to each other on both sides of the stacking station 112. The telescopic support blocks 21 can move towards each other to form a material supporting surface. The telescopic support blocks 21 can extend and retract in various ways. For example, the telescopic support blocks 21 are connected to a linear drive mechanism that drives their linear movement back and forth. The linear drive mechanism can be a cylinder or a motor. Alternatively, the telescopic support blocks 21 can be oscillating on the frame 1, that is, the telescopic support blocks 21 can extend and retract by oscillation. When the telescopic support block 21 is set to swing, one end of the telescopic support block 21 is hinged to the mounting base 22 on the frame 1, and the mounting base 22 is threadedly connected to the frame 1. The telescopic support block 21 is hinged to the mounting base 22 through a hinge shaft. The other end is provided with a protrusion 211 that can slide along the guide groove 221 of the mounting base 22 to ensure that the telescopic support block 21 moves along the trajectory of the guide groove 221. There is a return spring 23 between the mounting base 22 and the locking block. The return spring automatically restores the telescopic support block 21 to the initial position. In addition, the guide groove 221 can limit the swing angle of the telescopic support block 21 to ensure the stability of the material support. The structure is simple and the manufacturing cost is low.

[0022] The lifting and stacking mechanism includes a primary lifting stacking platform 31 and a lifting drive assembly 32. The primary lifting stacking platform 31 can be plate-shaped or have several strips forming a support surface for supporting materials. The primary lifting stacking platform 31 has clearance space to avoid telescopic support blocks 21. The width of the support surface of the primary lifting stacking platform 31 can be smaller than the distance between the relatively arranged telescopic support blocks 21, or a material-supporting groove can be opened on the primary lifting stacking platform 31 for the telescopic support blocks 21 to pass through. The lifting drive assembly 32 drives the primary lifting stacking platform 31 to move up and down between the feeding station 111 and the stacking station 112. The lifting drive assembly 32 can be a linear drive mechanism such as a cylinder or a belt conveyor. The primary lifting stacking platform 31 moves the material to the stacking station, realizing vertical stacking of materials and preventing the materials from arching in the subsequent packaging process, thereby ensuring packaging quality.

[0023] The lifting and unloading mechanism includes a secondary lifting discharge platform 41, a horizontal drive component 42, and a vertical drive component. The secondary lifting discharge platform 41 is positioned above the primary lifting stacking platform 31. The horizontal drive component 42 drives the secondary lifting discharge platform 41 to extend into or out of the vertical stacking channel 11 in the left-right direction. The left guide plate 91 and right guide plate 92 are respectively provided with gaps for the secondary lifting discharge platform 41 to pass through. The vertical drive component drives the secondary lifting discharge platform 41 to reciprocate in the vertical direction. The horizontal drive component 42 and the vertical drive component can employ existing linear drive mechanisms (such as belt drives or cylinders). Furthermore, the unloading operation platform can utilize existing avoidance methods to prevent interference with the telescopic support block 21.

[0024] During operation, the lifting stacking platform 31 picks up material at the feeding station 111 and moves upward to the stacking station 112. Simultaneously, the telescopic support block 21 retracts to allow space. After reaching the stacking station 112, the telescopic support block 21 extends, and the platform descends. During descent, the telescopic support block 21 passes through the clearance space, leaving the material on the material support surface. The platform then returns to the feeding station 111 and repeats the lifting and picking action. Simultaneously, the telescopic support block 21 retracts during the upward movement of the platform and remains extended during descent to support the existing stack. The lifting stacking platform 31 and the telescopic support block 21 repeat these actions until the material at the stacking station 112 reaches a predetermined value.

[0025] After the primary lifting stacking platform 31 returns to the feeding station 111, the horizontal drive component 42 drives the secondary lifting discharge platform 41 into the stacking station 112, and the vertical drive component drives the secondary lifting discharge platform 41 to move upward, lifting the predetermined amount of material to the discharge station 113, waiting for the next packaging process.

[0026] To reduce waiting time between processes and improve efficiency, the vertical stacking channel 11 also includes a waiting station 114, located between the stacking station 112 and the unloading station 113. The waiting station 114 is also equipped with a support component 2, and telescopic support blocks 21 with the same structure as described above are respectively set on the front and rear sides of the waiting station 114 to support the materials. The lifting drive component has a material stacking mode and an overall lifting mode. In the material stacking mode, the lifting drive component drives the single-lift stacking platform 31 to move from the feeding station 111 to the stacking station 112. In the overall lifting mode, the lifting drive component drives the single-lift stacking platform 31 to move from the feeding station 111 to the waiting station 114. In the material stacking mode, the lifting drive component drives the single-lift stacking platform 31 to push a fixed number of materials to the stacking station 112 for layer-by-layer stacking. The preset packaging quantity is equal to the quantity of a single stack multiplied by the number of stacks, and the lifting drive component switches to the overall lifting mode for the last stacking action. For example, if the preset packaging quantity is 100 paper bags, and the material stacking mode pushes 10 paper bags, then the first 9 executions of the material stacking mode will complete the layer-by-layer stacking of 90 paper bags. The 10th execution will switch to the overall lifting mode, lifting the accumulated 100 paper bags to the waiting station 114 at once. The vertical drive component drives the secondary lifting discharge platform 41 to move up and down back and forth between the waiting station 114 and the discharge station 113. While the secondary lifting discharge platform 41 is picking up materials, the primary lifting stacking platform 31 can continue to pick up materials and perform stacking operations, making the connection between the lifting material picking mechanism and the lifting stacking mechanism smoother and improving work efficiency.

[0027] The secondary lifting discharge platform 41, which is set on one side of the frame 1, is prone to deformation due to the cantilever effect, causing the material to tilt. In order to reduce this impact, the secondary lifting discharge platform 41 has two sets, which are set opposite to each other on the left and right sides of the vertical stacking channel 11. Each set of the secondary lifting discharge platform 41 is independently connected to a horizontal drive component 42 and a vertical drive component, which shortens the length of a single set of secondary lifting discharge platform 41. The force distribution of the secondary lifting discharge platform 41 set on both the left and right sides is uniform, reducing the risk of deformation.

[0028] To ensure the material is more compacted during packaging and thus guarantees packaging quality, a limiting top plate 5 is installed at the discharge station 113. When a left and right baffle are present, the left and right baffles pass through the limiting top plate 5 and are mounted on the frame 1. The lower surface of the limiting top plate 5 and the upper surface of the secondary lifting discharge platform 41 form a height-adjustable pressing space. The four corners of the limiting top plate 5 are connected to the vertical guide rail via sliders to achieve adjustable pressing space. Furthermore, when the secondary lifting discharge platform 41 moves upward, the limiting top plate 5 remains stationary, further compacting the material. (Compacting the material improves packaging quality.) To achieve automatic feeding, a feeding conveyor belt 6 is connected between the feeding station 111 and the bag-making device. Feeding push plates 61 are spaced apart on the conveying surface of the feeding conveyor belt 6. The feeding conveyor belt 6 is connected to the bag-making device to realize integrated bag stacking. The feeding push plates 61 push the material into the one-time lifting stacking platform 31 at the feeding station 111. However, because the conveyor belt is arranged in a loop, there is a gap between the feeding station 111 and the feeding conveyor belt 6. To ensure that the material enters the feeding station 111 stably, a connecting mechanism is provided between the feeding conveyor belt 6 and the one-time lifting stacking platform 31. The connecting mechanism includes a transition plate 7 and a connecting push plate 72. The transition plate 7 connects the feeding station 111 and the feeding conveyor belt 6. The transition plate 7 is fixedly installed on the frame 1 to prevent the material from falling from the gap between the feeding station 111 and the feeding conveyor belt 6. The transition plate 7 has a pushing clearance gap 71 for the feeding push plate 61 to pass through. The pushing clearance gap 71 allows the feeding push plate 61 to move downward to achieve a circular trajectory movement. The connecting push plate 72 is staggered with the feeding push plate 61 to avoid collision between the connecting plate and the feeding push plate 61. The connecting push plate 72 is connected to the avoidance drive mechanism 721 that moves left and right and the push drive mechanism 722 that drives it to move back and forth. The avoidance drive mechanism 721 drives the connecting push plate 72 to move left and right, and the push drive mechanism 722 drives the connecting push plate 72 to move back and forth. In this embodiment, the length of the transition plate 7 is slightly smaller than the length of the material, so both ends of the material will extend out of the transition plate 7. In order to stably convey the material, the connecting push plate 72 has two sets, which are respectively set on both sides of the transition plate 7. When the feeding push plate 61 pushes the material to the transition plate 7, it rotates through the pushing gap. The avoidance drive mechanism 721 then drives the two sets to move relative to each other, so that the connecting push plate 72 contacts the rear side of the material. Then the push drive mechanism 722 drives the connecting push plate 72 to push the material onto the primary lifting stacking platform 31 of the feeding station 111.

[0029] To ensure the neatness of the materials at the feeding station 111, the feeding station 111 is also equipped with relatively movable correction plates 8. The correction plates 8 are set on the left and right sides of the one-time lifting stacking platform 31. The moving direction of the correction plates 8 is perpendicular to the extension direction of the vertical stacking channel 11. The correction plates 8 on both sides are connected to cylinders respectively. Each cylinder drives its respective correction plate 8 to move towards each other in the left and right direction to correct the material, avoid misaligned stacking of materials, prevent material jamming when rising, and ensure the quality of subsequent packaging.
