Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a strapping and packaging machine. Background Technology

[0002] A strapping and packing machine is a packaging device used to automatically strap and secure items. It mainly uses strapping tape to wrap, tighten, weld, or snap together items such as cartons, pallets, and packages to form a sturdy packaging unit. It can be fully automatic, semi-automatic, or manual, depending on the needs, and is suitable for packaging scenarios of items of different sizes and weights.

[0003] The publication number CN118811169A discloses a feeding, lifting, bundling, and forming integrated machine, which relates to the technical field of feeding, lifting, bundling, and forming integrated machines. It includes a feeding rack mechanism, a bundling machine mechanism, a feeding rack mechanism, a pressing mechanism, and a pushing rack mechanism. In this invention, the feeding, lifting, bundling, and forming integrated machine achieves efficient automated operation by integrating the feeding rack mechanism, the bundling machine mechanism, the feeding rack mechanism, the pressing mechanism, and the pushing rack mechanism. The design of the feeding rack mechanism effectively controls the transmission and positioning of the material belt, the strapping machine mechanism ensures the stability and accuracy of the strapping process, the feeding rack mechanism provides reliable feeding capacity, the pressing mechanism enhances the uniformity and stability of pressing, and the pushing rack mechanism further improves the material pushing efficiency. However, this technology has the following technical problems: 1. The pushing rack mechanism lacks a material fixing mechanism. During the pushing process, materials that are too light or too small will fall, affecting subsequent work; 2. The feeding mechanism lacks a storage mechanism. When the conveyor transports materials to the storage mechanism, the bottom material will become disordered due to its height, and it cannot support the strapping and packaging of thick materials; 3. The feeding mechanism lacks a blocking mechanism, leading to messy material stacking during the feeding process. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a strapping and packaging machine to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strapping and baling machine, comprising a frame, a feeding mechanism, a pressing mechanism, a pushing plate mechanism, and a baling mechanism, characterized in that: the frame is provided with a material storage mechanism capable of lifting and lowering for material storage on one side of the feeding mechanism, the material storage mechanism is linked with the pressing mechanism, the material storage mechanism gradually descends as the pressing mechanism presses down, and the frame is also provided with a stop bar mechanism on one side of the feeding mechanism for stopping material storage when the material storage mechanism is in use.

[0006] With the above technical solution, the frame is equipped with a storage mechanism and a stop mechanism on one side of the feeding structure. When the pressing mechanism presses down, the storage mechanism gradually descends simultaneously, which not only avoids the problem of stacking disorder caused by excessive material stacking height, but also provides stable support to support the bundling requirements of thicker materials, thus improving the applicability of the equipment to materials of different specifications. At the same time, the stop mechanism added to the frame on the side of the feeding mechanism can form a lateral abutment limit on the material during the storage process, effectively preventing the material from stacking disorderly due to inertia or positional deviation during the discharge, and ensuring that the material always remains neatly arranged.

[0007] The aforementioned strapping and baling machine can be further configured such that: the material storage mechanism includes lifting and lowering mounting plates disposed on both sides of the frame, the mounting plates having a base plate for placing materials, and the frame having a first drive assembly capable of driving the mounting plates to lift and lower.

[0008] Using the above technical solution, when the materials on the frame are being packaged, the drive frame structure lifts the mounting plate and the base plate, the feeding structure feeds the materials, the pressing mechanism presses down, and the base plate gradually descends as the feeding structure feeds the materials, thus avoiding the disorderly stacking of materials and meeting the packaging requirements for high thickness.

[0009] The aforementioned strapping and packaging machine can be further configured as follows: the first drive assembly includes a first drive motor installed in the frame; the frame is rotatably provided with a first rotating shaft; the first rotating shaft is linked to the first drive motor, causing the first drive motor to drive the first rotating shaft to rotate; the frame is vertically provided with a moving slot; the first rotating shaft is placed at the bottom of the moving slot and has first sprockets at both ends; a second sprocket is provided at the end of the moving slot away from the first sprockets; a third sprocket is sleeved in the middle of the first rotating shaft; a fourth sprocket is provided on one side of the first drive motor; the third and fourth sprockets, as well as the first and second sprockets, are synchronously connected by a chain; the mounting plate is provided with a connector located in the moving slot; one end of the connector passes through the moving slot and is fixedly connected to the mounting frame, and the other end is connected to the chain.

[0010] Using the above technical solution, the first drive motor drives the first sprockets at both ends to rotate through the first rotating shaft. The arrangement of the third and fourth sprockets allows the output torque of the drive motor to be evenly applied to the first rotating shaft through the chain. The mounting plate is connected to the chain through the connector, which enables the rotation of the first drive motor to drive the mounting plate to move vertically back and forth along the moving groove.

[0011] The aforementioned strapping and baling machine can be further configured such that: the stop mechanism includes a fixed truss with the frame located on one side of the feeding mechanism, a connecting shaft for rotatably connecting several stop rods is provided between the fixed trusses, the stop rods abut against the material, and a second driving component for driving the connecting shaft to rotate is provided on one or both sides of the fixed truss, the second driving component being able to drive the stop rods to rotate.

[0012] Using the above technical solution, several stops on the fixed truss are linked to the second drive assembly through a connecting shaft. During the material conveying process of the conveying device, the stops directly abut against the side of the material and apply a lateral alignment force. After the conveying device finishes conveying, the second drive assembly drives the stops to rotate and lift to one side, and the material is then conveyed to the packaging mechanism for packaging through the push plate mechanism.

[0013] The aforementioned strapping and packaging machine can be further configured such that: the second drive component includes a first telescopic cylinder disposed on one or both sides of a fixed truss, a transmission rack is fixedly connected to the end of the first telescopic cylinder, the connecting shaft passes through the fixed truss and is provided with a transmission gear at the end, and the transmission gear meshes with the transmission rack.

[0014] Using the above technical solution, the linear motion of the first telescopic cylinder is converted into the rotational motion of the connecting shaft through the meshing of the transmission rack and transmission gear. The rotation of the connecting shaft can drive the stop lever to rotate to one side. At the same time, the overall structure has fewer parts and is easier to maintain. Compared with complex multi-link or cam mechanisms, it reduces the equipment failure rate and maintenance costs.

[0015] The aforementioned strapping and packaging machine can be further configured such that: the fixed truss and the mounting plate are connected by an adjustment structure, the adjustment structure enabling the fixed truss to be axially adjusted between the feeding mechanism and the packaging structure.

[0016] By adopting the above technical solution, the axial position adjustment of the stop mechanism between the feeding mechanism is realized through the adjustable connection between the fixed truss and the frame, enabling the stop mechanism to adapt to materials of different sizes.

[0017] The aforementioned strapping and baling machine can be further configured such that: the adjustment structure includes a rod seat disposed on the top of the mounting plate, a movable rod is disposed between the rod seats, the movable rod is disposed along the extension direction of the frame, a first slider is slidably disposed on the movable rod, and the fixed truss is fixedly installed on the top of the first slider.

[0018] Using the above technical solution, the moving rod is arranged along the extension direction of the frame, and the slider can slide along its axial direction and drive the fixed truss to move synchronously, so as to meet the alignment requirements under different material specifications.

[0019] The aforementioned strapping and baling machine can be further configured such that: the push plate mechanism includes a push plate disposed on one side of the feeding mechanism; the frame is provided with a third driving component for driving the push plate to reciprocate along the extension direction of the frame; the push plate has several mounting cavities; and the mounting cavities are provided with a pressing and fixing structure for pressing and fixing the material after feeding is completed.

[0020] By adopting the above technical solution, after the feeding mechanism completes the material conveying, the pressing structure can apply downward pressure to the material before and during the pushing process, which effectively solves the problem of the material falling during pushing due to its lightness or small size in the prior art, and ensures that the material remains stable in the pushing path.

[0021] The aforementioned strapping and baling machine can be further configured such that: the clamping structure includes a fixed plate disposed on one side of the mounting cavity, a second telescopic cylinder is fixedly mounted on the top of the fixed plate, a pressure block is hinged to the end of the second telescopic cylinder, and a support member is also provided on the top of the second telescopic cylinder as a support for the pressure block, the support member is hinged to the pressure block, the pressure block passes through the mounting cavity, and when the second telescopic cylinder extends, it causes the pressure block to abut against the material.

[0022] Using the above technical solution, the second telescopic cylinder is fixedly installed on the upper end of the fixed plate, and its end is hinged to the pressure block. The support member is also hinged to the pressure block. During the process of the telescopic cylinder extending to make the pressure block come into contact with the material, the support member can effectively support and guide the pressure block to prevent the pressure block from shifting or deforming under pressure. When the telescopic cylinder extends, it lifts the end of the pressure block and presses the material down with the hinge point of the support member as the center to fix the material.

[0023] The aforementioned strapping and baling machine can be further configured such that: the third drive assembly includes mounting frames disposed on both sides of the frame for connection to slide rails; a second slider is slidably disposed on the slide rail; a mounting block is disposed on the top of the second slider; a push plate truss for fixed connection to a push plate is disposed between the mounting blocks; first synchronous pulleys are disposed at both ends of the slide rail; a second drive motor is disposed on one side of the frame; the second drive motor passes through the frame and is provided with a second synchronous pulley; a third synchronous pulley is disposed on one side of the first synchronous pulley; the first synchronous pulleys are connected to each other and the second synchronous pulleys are connected to the third synchronous pulleys by a synchronous belt; the synchronous belt between the first synchronous pulleys is placed between the mounting block and the second slider and clamps and fixes the mounting block and the second slider.

[0024] Using the above technical solution, the first synchronous pulleys at both ends of the slide rail are connected by a synchronous belt. The synchronous belt is clamped and fixed between the mounting block and the second slider, so that the linear motion of the synchronous belt can be directly converted into the reciprocating motion of the push plate truss. The second drive motor is connected to the second synchronous pulley and the third synchronous pulley by the synchronous belt. At the same time, the third synchronous pulley is connected to the first synchronous pulley, which enables the drive motor to drive the first synchronous pulley to rotate. The rotation of the first synchronous pulley can drive the back axis to reciprocate.

[0025] The beneficial effects of this utility model are:

[0026] 1. A pressure-fixing structure is set in the push plate. When the telescopic cylinder extends, the telescopic cylinder lifts the end of the pressure block and presses the material down with the hinge point of the support as the center to fix the material.

[0027] 2. The frame is equipped with a lifting mounting plate, and the top of the mounting plate is equipped with a base plate for material storage. At the same time, there is a drive structure inside to drive the mounting plate to lift. When the material on the frame is being packaged, the drive frame structure drives the mounting plate and the base plate to rise. The base plate gradually descends as the feeding structure feeds the material, avoiding the disorderly stacking of materials.

[0028] 3. Several stops on the fixed truss are linked to the second drive assembly through connecting shafts. During the material conveying process, the stops directly abut against the side of the material and apply lateral alignment force to avoid the material from stacking messily.

The storage mechanism and the stop bar 18 mechanism are located on the side of the feeding mechanism 1. When the pressing mechanism 3 presses down, the storage mechanism gradually descends synchronously, avoiding the problem of disorder caused by excessive material stacking height, and also allowing for continuous lifting. To provide stable support for the bundling of materials with greater thickness, the equipment's applicability to materials of different specifications is improved. Simultaneously, a stop bar 18 mechanism added to one side of the feeding mechanism 2 on the frame 1 can provide lateral contact and limit the material during storage, effectively preventing the material from piling up and becoming disorderly due to inertia or positional deviation during unloading, ensuring that the material always remains neatly arranged. The storage mechanism includes lifting mounting plates 6 located on both sides of the frame 1. The mounting plates 6 have base plates 7 for placing materials.

The second driving assembly can drive the stop bars 18 to rotate. The plurality of stop bars 18 on the fixed truss 17 are linked with the second driving assembly through the connecting shaft 19. When the conveying device conveys the material... During the process, the baffle 18 directly abuts against the side of the material and applies a lateral alignment force. After the conveying device finishes conveying, the second drive assembly drives the baffle 18 to rotate and lift to one side. The material is then conveyed to the packaging mechanism 5 through the push plate 26 mechanism 4 for packaging. The second drive assembly includes a first telescopic cylinder 20 set on one or both sides of the fixed truss 17. A transmission rack 21 is fixedly connected to the end of the first telescopic cylinder 20. The connecting shaft 19 passes through the fixed truss 17 and is provided with a transmission gear 22 at the end. The transmission gear 22 meshes with the transmission rack 21. The first telescopic cylinder 20... The linear motion of cylinder 20 is converted into the rotational motion of connecting shaft 19 through the meshing of transmission rack 21 and transmission gear 22. The rotation of connecting shaft 19 can drive the stop lever 18 to rotate to one side. At the same time, the overall structure has fewer parts and is easier to maintain. Compared with complex multi-link or cam mechanisms, it reduces the equipment failure rate and maintenance costs. The fixed truss 17 and the mounting plate 6 are connected by an adjustment structure. The adjustment structure can make the fixed truss 17 axially adjustable between the feeding mechanism 2 and the packaging structure.

When the telescopic cylinder extends... The telescopic cylinder lifts the end of the pressure block 30 and presses the material down with the hinge point of the support member 31 as the center, thus fixing the material. The third drive assembly includes mounting brackets 33 on both sides of the frame 1 for connecting to the slide rail 32. The slide rail 32 is slidably equipped with a second slider 34.

The synchronous belt 41 between the first synchronous pulleys 37 is placed between the mounting block 35 and the second slider 34 and clamped and fixed between the mounting block 35 and the second slider 34. The first synchronous pulleys 37 at both ends of the slide rail 32 are connected by the synchronous belt 41. The synchronous belt 41 is clamped and fixed between the mounting block 35 and the second slider 34, so that the linear motion of the synchronous belt 41 can be directly converted into the reciprocating motion of the push plate truss 36. The second drive motor 38 is connected to the second synchronous pulley 39 and the third synchronous pulley 40 through the synchronous belt 41.
