[0002] Heavy bag packaging machines are automated packaging equipment mainly used for packaging materials such as powders, ultrafine powders, granules, and flakes. Heavy bag packaging machines can automatically perform bag picking and loading operations, effectively reducing manual intervention and improving production efficiency. With the help of high-precision weighing sensors and weighing controllers, they ensure accurate measurement of materials.

[0003] In existing technologies, heavy bag packaging machines are used in conjunction with a bag feeding mechanism. After the bag feeding mechanism picks up the bag, the heavy bag packaging machine transfers it to the area below the feeding port for loading. The heavy bag packaging machine mainly relies on a mechanical structure to drive the bag clamping unit and the bag supporting unit to pick up the bag from the bag feeding mechanism. The mechanical structure that drives the bag clamping unit and the bag supporting unit uses a large number of cylinders as power, which is not only complex in construction and has many control units, but also results in poor stability during equipment operation. Summary of the Invention

The first sealing plate and the second sealing plate constitute a material guiding assembly. As an extension of the main feed hopper, the material guiding assembly moves between the bag feeding area and the filling area by deflecting the bag clamping unit and the bag supporting unit. The deformation generated by the linkage mechanism changes the opening size of the material guiding assembly.

[0008] Preferably, the linkage mechanism includes a crank, a first deflecting rod, a second deflecting rod, and a connecting shaft seat; The first deflecting rod and the second deflecting rod are fixedly connected to the first shaft and the second shaft, respectively. The connecting shaft seat is disposed on the second deflecting rod. The crank rod is hinged to the connecting shaft seat. The end of the crank rod away from the connecting shaft seat is rotatably connected to the third shaft through a bearing.

[0009] The end of the second deflecting rod away from the second shaft is connected to the end of the first deflecting rod away from the first shaft via gear meshing.

[0013] Compared with the prior art, the embodiments of this application have the following main advantages: 1. The high-efficiency heavy bag packaging machine feeding and bag clamping mechanism provided by the present invention uses the first sealing plate and the second sealing plate as the carrier of the bag clamping unit and the bag supporting unit. The first sealing plate and the second sealing plate realize their own deformation under the action of the linkage mechanism, thereby improving the success rate of bag picking by actively reducing the opening and reducing the influence of the structure near the feeding port on the bag picking process.

[0014] 2. The high-efficiency heavy bag packaging machine feeding and bag clamping mechanism provided by the present invention achieves two functions, deflection and deformation, through the linkage effect of transmission components and drive unit.

Through deflection motion, the bag clamping unit and the bag supporting unit are pulled to move in the bag supply area and the filling area to complete the bag picking and bag filling operation. This reduces the number of moving parts in the feeding and bag clamping structure, reduces the complexity of the moving structure in the equipment, and uses a mechanical linkage structure to reduce the number of control lines, thereby improving the stability of equipment operation.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This invention provides a high-efficiency bag-feeding and bag-clamping mechanism for a heavy-duty bag packaging machine, such as... Figures 1-8 As shown, the high-efficiency heavy bag packaging machine's unloading and bag clamping mechanism includes: The unloading unit 100 includes a main feeding bin 110, a first sealing plate 120 and a second sealing plate 130. The first sealing plate 120 and the second sealing plate 130 are respectively disposed on both sides of the main feeding bin 110. The main feeding bin 110, the first sealing plate 120 and the second sealing plate 130 are connected by two sets of transmission components 140. The machine body unit 200 includes a platform 210, a frame 220, and a storage bin 230. The storage bin 230 is located above the platform 210 and is connected to the unloading unit 100 located below the platform 210. After the material is injected into the storage bin 230, it is weighed and proportioned by the storage bin 230 and then released into the main feed bin 110 in the unloading unit 100, and then guided into the packaging bag by the main feed bin 110. A drive unit 300 includes a transmission mechanism and a power unit. The transmission mechanism includes a deflection shaft 310 and a connecting rod assembly 320 connected to the deflection shaft 310. The power unit includes a driven wheel 330, a driving wheel 340, and a motor module 350 mounted on a platform 210. The driven wheel 330 and the driving wheel 340 are connected by a chain. The driving wheel 340 is mounted on the power output shaft of the motor module 350, and the driven wheel 330 is mounted at one end of the deflection shaft 310. The motor module 350 generates power and transmits it to the connecting rod assembly 320. The connecting rod assembly 320 is connected to a second sealing plate 130. The second sealing plate 130 deflects around the main feed bin 110 under the drive of the drive unit 300. Under the drive of the transmission assembly 140, the first sealing plate 120 deflects around the main feed bin 110 synchronously with the second sealing plate 130. The transmission assembly 140 includes a crossbeam 141, a crank 142, a first deflecting rod 1431 and a second deflecting rod 1432, and a connecting shaft seat 144; The first sealing plate 120 and the second sealing plate 130 are both rotatably connected to the cross frame 141. The main feed bin 110 is provided with a main deflection shaft 112. The cross frame 141 is mounted on the main deflection shaft 112 via bearings. The side of the second sealing plate 130 away from the first sealing plate 120 generates a deflection force under the traction of the connecting rod assembly 320, causing the cross frame 141 to rotate around the main deflection shaft 112. At the same time, the first sealing plate 120 and the second sealing plate 130, which are rotatably connected to the cross frame 141, will also deflect around the main deflection shaft 112 under the action of the cross frame 141. The first deflection rod 1431 and the second deflection rod 1432 are respectively connected to the second sealing plate 130 provided on the first sealing plate 120, and the first deflection rod 1431 and the second deflection rod 1432 are connected by a rack and pinion meshing. The connecting shaft seat 144 is disposed on the second deflecting rod 1432, and the first sealing plate 120 and the second sealing plate 130 are respectively provided with the first shaft 122 and the second shaft 132. The first sealing plate 120 and the second sealing plate 130 are fixedly connected to the first shaft 122 and the second shaft 132. When the connecting shaft seat 144 is hinged to the crank 142, the other end of the crank 142 is rotatably connected to the main feed bin 110. When the first sealing plate 120 and the second sealing plate 130 deflect and move under the traction of the cross frame 141, the connecting rod structure formed by the crank 142 and the connecting shaft seat 144 will cause the second deflecting rod 1432 to rotate around the second shaft 132; at the same time, the meshing structure between the second deflecting rod 1432 and the first deflecting rod 1431 will cause the first deflecting rod 1431 to rotate around the first shaft 122, and the first shaft 122 and the second shaft 132 will cause the first sealing plate 120 and the second sealing plate 130 to rotate and deflect around the first shaft 122 and the second shaft 132. During the deflection process, the first sealing plate 120 and the second sealing plate 130 will move closer to or further away from each other; The first sealing plate 120 and the second sealing plate 130 are provided with a bag clamping unit 400 on their outer sides. The body unit 200 is provided with a bag supply structure (not shown in this application) on the side away from the drive unit 300. The area with the bag supply structure is the bag supply area, and the area below the platform 210 is the material loading area. The material guiding assembly composed of the first sealing plate 120 and the second sealing plate 130 will deflect towards the bag supply area or the material loading area under the drive of the drive unit 300. The bag feeding structure here utilizes existing technology. When the material guiding assembly deflects towards the bag feeding area, the driving unit 300 drives the first sealing plate 120 and the second sealing plate 130 to deflect towards the bag feeding structure. The first sealing plate 120 and the second sealing plate 130 then approach each other, forming a sharp angle structure. This increases the distance between the bag clamping units 400, reducing the impact of the first sealing plate 120 and the second sealing plate 130 on the bag clamping unit 400. Meanwhile, the bag clamping unit 400 adsorbs and pulls the packaging bag. Simultaneously, the bag supporting unit 500 provided on the first sealing plate 120 and the second sealing plate 130 extends into the packaging bag, ensuring the packaging bag is completely sealed. Fully open; when the material guiding assembly deflects to the side of the loading area, the drive unit 300 drives the first sealing plate 120 and the second sealing plate 130 away from the side of the bag supply structure. Under the packaging of the transmission assembly 140, the first sealing plate 120 and the second sealing plate 130 open away from each other. When the packaging bag reaches below the main feeding bin 110, the first sealing plate 120 and the second sealing plate 130 open to the maximum extent. The material falling from the main feeding bin 110 is guided by the first sealing plate 120 and the second sealing plate 130 and slides into the packaging bag. The bag clamping unit 400 and the bag supporting unit 500 in this application are both prior art equipment. In this application, the first sealing plate 120 and the second sealing plate 130 serve as carriers for the bag clamping unit 400 and the bag supporting unit 500. The bag clamping unit 400 and the bag supporting unit 500 are pulled by deflection motion to complete the bag picking operation. Furthermore, the first sealing plate 120 and the second sealing plate 130 complete their own opening and closing action under the linkage of the transmission component 140, reducing the influence of the structure near the discharge port on the bag picking process. They utilize their own deformation to improve the success rate of the bag picking process and enhance the efficiency of the bag picking process. At the same time, the linkage effect of the transmission component 140 and the drive unit 300 reduces the number of moving parts, reduces the complexity of the equipment's motion structure, thereby reducing the number of control lines and improving the stability of equipment operation. In a preferred embodiment of this invention, the main feed bin 110 includes a funnel bin body 111, a main deflection shaft 112, and a third shaft 113; the funnel bin body 111 has a through structure, and the platform 210 is provided with a discharge port for accommodating materials to pass through, and the upper end face of the funnel bin body 111 is connected to the periphery of the discharge port. The main deflection shaft 112 and the third shaft 113 are both mounted on the funnel body 111. The main deflection shaft 112 is rotatably connected to the cross frame 141 via a bearing. The third shaft 113 serves as the hinge end of the crank 142. Here, the crank 142 and the connecting shaft seat 144 form a set of connecting rod structures. When the second sealing plate 130 moves under the drive of the transmission mechanism, the crossbeam 141 deflects around the main deflection shaft 112. At the same time, the first sealing plate 120 also deflects around the main deflection shaft 112 under the action of the crossbeam 141. Since the first sealing plate 120 and the second sealing plate 130 are both connected to the crossbeam 141 by a rotatable connection, and the linkage mechanism formed by the crank 142, the connecting shaft seat 144, the first deflection rod 1431 and the second deflection rod 1432 ensures that the first sealing plate 120 and the second sealing plate 130 will not deflect freely during the rotation of the crossbeam 141, the opening between the first sealing plate 120 and the second sealing plate 130 is effectively controlled through the linkage mechanism. In a preferred embodiment of this invention, the first sealing plate 120 includes a first sealing plate body 121 and a first shaft 122 disposed on the first sealing plate body 121; the second sealing plate 130 includes a second sealing plate body 131 and a second shaft 132 disposed on the second sealing plate body 131, and the first sealing plate body 121 and the second sealing plate body 131 are respectively disposed on both sides of the funnel chamber 111. The first sealing plate 121 and the second sealing plate 131 are rotatably connected to the cross frame 141 via the first shaft 122 and the second shaft 132, respectively. Without the restriction of the linkage mechanism, when the second sealing plate 131 moves under the traction of the transmission mechanism, the first sealing plate 121 and the second sealing plate 131 will point towards the ground under the action of rotation and gravity. However, under the restriction of the linkage mechanism, the first sealing plate 121 and the second sealing plate 131 will be restricted to the direction and point to a suitable area under the traction of the cross frame 141. Furthermore, the linkage mechanism controls the opening size of the first sealing plate 121 and the second sealing plate 131 during the deflection process. The cross frame 141 is provided with three sets of bearing structures. The main deflection shaft 112, the first shaft 122 and the second shaft 132 are respectively assembled in different bearings. The first shaft 122 and the second shaft 132 are respectively located on both sides of the main deflection shaft 112. In this embodiment, because the second sealing plate 130 deflects around the main deflection shaft 112 under the drive of the transmission mechanism, the first shaft 122 and the second shaft 132 will deflect around the main deflection shaft 112 under the traction of the cross frame 141. The positions of the crank 142 and the connecting shaft seat 144 change during the deflection process. Under the limiting action of the crank 142, the second deflection rod 1432, which is fixedly connected to the connecting shaft seat 144, will also rotate around the axis of the second shaft 132. Since the second deflection rod 1432 and the second shaft 132 are fixedly connected, the second deflection rod 1432... As 432 rotates, the second shaft 132 rotates synchronously, and the second sealing plate 131 rotates accordingly, changing its orientation. The end of the second deflecting rod 1432 away from the second shaft 132 meshes with the end of the first deflecting rod 1431 away from the first shaft 122. When the second deflecting rod 143 and the second shaft 132 rotate synchronously, the first deflecting rod 1431 and the first shaft 122 rotate synchronously under the deflection of the rack, changing the orientation of the first sealing plate 121; thus changing the size of the opening between the first sealing plate 121 and the second sealing plate 131. It should be noted that there are two sets of the main deflection shaft 112, the first shaft 122 and the second shaft 132, which are respectively arranged on different end faces of the funnel body 111, the first sealing plate 121 and the second sealing plate 131, for connecting different transmission components 140. In a preferred embodiment of this invention, the linkage assembly 320 includes a first linkage 321, a second linkage 322, and a connecting seat 323. The first linkage 321 is fixedly connected to the deflection shaft 310. The two ends of the second linkage 322 are respectively hinged to the end of the first linkage 321 away from the deflection shaft 310 and the connecting seat 323. The connecting seat 323 is fixed to the second sealing plate 131. In this embodiment, when the deflection shaft 310 rotates under the traction of the drive unit, the connecting rod assembly 320 will pull the second sealing plate 131 to deflect and move as a whole; during the movement of the second sealing plate 131 as a whole, the transmission assembly 140 pulls the first sealing plate 120 to rotate synchronously, completing the orientation and opening and closing actions of the first sealing plate 120 and the second sealing plate 130. It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
