[0013] The above technical solutions of the present invention have the following advantages compared with the prior art: For the ton bag packing machine of the present invention, the ton bag packing machine can be operated by a single person for hanging the bag and putting on the bag, without the need for the body to cross the guardrail, greatly reducing the labor intensity of workers and improving the safety of the working environment. At the same time, the simplified lifting mechanism not only reduces the complexity of the equipment, but also improves the production efficiency and assembly convenience, significantly reducing the labor and maintenance costs, being safer and more reliable during use, and having a lower operation error rate.

[0014] The ton bag packaging machine optimizes the density of the material by setting up a vibrator mechanism, which can effectively ensure the quality of the material and reduce material loss and environmental pollution. During the debugging process, the proximity sensor position in the weighing and film hanging mechanism can be adjusted according to the needs of the operator, so that the bag clamping device of the bag hanging and bagging mechanism can be accurately placed under the push of the rotating cylinder.

[0016] The weighing and film hanging mechanism of the ton bag packaging machine can realize the automatic rotation of the swing arm and the bag clamping device by setting the first drive device and the second drive device, so that one person can easily complete the bag hanging and bagging operations, greatly reducing the operation steps and significantly improving the operation convenience and work efficiency.

[0017] The weighing and film hanging mechanism of the ton bag packaging machine adopts a weighing sensor and a stable mounting frame design, combined with a guide device and a supporting structure, which effectively avoids the tilting of the weighing frame or the movement of components, ensuring the accuracy and stability of the weighing data. Through the optimized arrangement of the guide mounting seat, bearing sleeve, self-aligning bearing and guide shaft, it effectively prevents the mounting frame from tilting or falling, and improves the stability and anti-interference ability of the overall structure of the equipment.

For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected, or electrically connected or capable of communicating with each other; they can be the communication inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0036] Refer to Figure 1 、 Figure 6 、 Figure 7 As shown, a bulk bag packing machine of the present invention includes: A feeding mechanism 3 for providing materials; A weighing and bag hanging mechanism, including a weighing device 6, a bag hanging device 7, a bag clamping device 717, a first driving device and a second driving device; wherein, the weighing device 6 includes a mounting frame body 605, a weighing sensor 601 arranged on the mounting frame body 605, and a weighing support 603 connected to the weighing sensor 601; the weighing sensor 601 is directly fixedly installed on the mounting frame body 605 by bolts, and the connecting piece mounting plate 602 directly falls on the weighing sensor 601 and is fixedly connected to the weighing support 603 by bolts; the bag hanging device 7 includes a bag hanging frame body 701 connected to the weighing support 603, a swing arm 711 rotatably connected to the bag hanging frame body 701, and a fixed arm fixedly connected to the bag hanging frame body 701, and the swing arm 711 and the fixed arm are both provided with bag hanging components 712 for hanging bulk bag hangers; the bag clamping device 717 is rotatably connected to the bag hanging frame body 701 and is used for sleeving the mouth of the bulk bag 8 and receiving the materials provided by the feeding mechanism 3 into the bulk bag 8, the swing arm 711 and the fixed arm are respectively arranged on both sides of the bag clamping device 717, the first driving device can drive the swing arm 711 to rotate towards the fixed arm direction, and the second driving device can drive the bag clamping device 717 to rotate towards the fixed arm direction; A traction mechanism 2 connected to the mounting frame body 605 for driving the weighing and bag hanging mechanism to lift and lower; A vibrator mechanism 13 located below the weighing and bag hanging mechanism for vibrating and compacting the materials in the bulk bag 8 on the weighing and bag hanging mechanism; A conveying mechanism 12 for conveying the bulk bag 8 after packaging is completed.

[0037] Refer to Figure 3 、 Figure 4 As shown, the feeding mechanism 3 includes: A box body 302 provided with a feeding channel, and the feeding channel includes a material dropping port and a discharging port; An arc door 307 movably connected to one side of the discharging port, and the arc door 307 includes a concave surface in an arc shape; A driving mechanism for driving the movement of the arc door 307 to open or close the material dropping port; A roller rotatably connected above the concave surface; Wherein, when the arc door 307 is opened to a predetermined state, the materials can fall to the concave surface through the material dropping port and are fed through the rotation of the roller.

[0038] In one embodiment, when the arc gate 307 is closed, one side of the concave surface is higher than the other side, and the roller is near the lower side of the concave surface; a predetermined gap is left between the roller and the concave surface.

[0039] The arc-shaped concave surface design of the arc gate 307 enables the material to naturally converge near the roller, improving the conveying efficiency. The predetermined gap between the roller and the concave surface is set as required to adapt to materials of different particle sizes. The gap between the roller and the feeding channel near the lower side of the concave surface is set according to actual needs.

[0040] It can be understood that the material falls between the higher side of the concave surface and the roller, and the rotation of the roller ( Figure 4 in the clockwise direction) drives the material to be conveyed towards the other side of the roller. When the other side of the roller and the lower side of the concave surface are opened, the material falls.

[0041] In one embodiment, referring to Figure 4 as shown, it further includes a baffle 317 installed at the side end of the feeding channel and a baffle rubber 318 pressed by the baffle 317. The baffle rubber 318 extends to the lower end of the discharging opening and is near the lower side of the concave surface. The baffle rubber 318 can contact the concave surface when the arc gate 307 moves. Ensure that there is no material leakage during the movement of the arc gate 307.

[0042] In one embodiment, referring to Figure 3 as shown, arc gate bearings 306 are respectively installed at both outer side ends of the box body 302. An arc gate shaft 305 rotatably connected to the two arc gate bearings 306 penetrates through the box body 302. The arc gate 307 is provided with a connecting arm connected to the arc gate shaft 305. One end of the arc gate shaft 305 is installed with an arc gate crank 310 connected to the driving end of the driving mechanism; the arc gate crank 310 is prevented from axially and radially moving through bolts and keys.

[0043] The driving mechanism includes a double-stroke cylinder 311 connected to the arc gate crank 310; wherein, when both pistons of the double-stroke cylinder 311 are closed, the arc gate 307 is driven to be fully opened; when one piston of the double-stroke cylinder 311 is opened, the arc gate 307 is driven to open the space between the lower side of the concave surface and the roller; when both pistons of the double-stroke cylinder 311 are opened, the arc gate 307 is driven to be fully closed.

[0044] Referring to Figure 3As shown, a feeding mechanism upper flange gasket 308 and a feeding mechanism lower flange gasket 301 are further provided on the box body 302. The box body 302 is butt-connected to a bin 1 through the feeding mechanism upper flange gasket 308, and the box body 302 is butt-connected to a blanking pipe 5 through the feeding mechanism lower flange gasket 301. The feeding mechanism upper flange gasket 308 and the feeding mechanism lower flange gasket 301 are both fixed by bolts to prevent material leakage and dust leakage.

[0045] In one embodiment, roller bearing seats 315 are installed at both outer ends of the box body 302. A roller pressing gasket 316 is provided between one of the roller bearing seats 315 and the box body 302. An electric motor seat 303 is further installed at the outer end of the box body 302. A roller shaft 313 that is connected to the roller and rotatably connected to the two roller bearing seats 315 penetrates through the box body 302. The roller shaft 313 is prevented from axially and radially moving through bolts and keys. The electric motor seat 303 is installed with an electric motor 304 connected to the roller shaft 313.

[0046] In one embodiment, a roller locking piece 314 is provided on one of the roller bearing seats 315 for adjusting the relative position between the roller shaft 313 and the box body 302; a roller plug piece 312 is provided between the end face of the box body 302 and the roller for convenient installation and to prevent material leakage.

[0047] In one embodiment, the box body 302 is further provided with a box door 320. A breathing cloth sleeve 321 is installed on the box door 320 through a hoop. The breathing cloth sleeve 321 provides air flow balance and reduces dust overflow; a box door gasket 319 is provided between the box door 320 and the box body 302 to prevent dust leakage.

[0048] When the feeding mechanism 3 is working, the arc door 307 is driven by a double-stroke cylinder 311 and can achieve three states: fully open, half open, and fully closed, and is linked with the roller to control the material flow. When feeding roughly, both pistons of the double-stroke cylinder 311 are compressed, driving the arc door 307 to open completely, and the electric motor 304 drives the roller shaft 313 to rotate to complete rough feeding. When approaching the set quality, one piston of the double-stroke cylinder 311 is opened, driving the arc door 307 to open half, and fine feeding is carried out relying on the roller shaft 313. As the quality gets closer, the rotation speed of the roller shaft 313 becomes slower and slower. When reaching the set quality, the roller shaft 313 stops rotating to block the material. At the same time, the other piston of the double-stroke cylinder 311 is opened, closing the arc door 307 completely, and scraping the material on the arc door 307 into the feeding channel through a baffle rubber 318.

[0049] The feeding mechanism 3 is designed with an arc gate 307 and a roller structure, which is compact in structure, optimizes the layout of the feeding device, requires no additional height space, avoids the limitations of the traditional double - helix feeding device with complex structure and large occupied height space, and is suitable for a smaller installation environment.

[0050] Through the coordinated operation of the roller and the arc gate 307 in the present invention, the rotation speed of the roller can precisely adjust the feeding rate of the material. By using the three control states (fully open, half - open, fully closed) of the arc gate 307, relatively precise control of the material flow rate is achieved.

[0051] Refer to Figure 9 As shown, two swing arms 711 and the fixed arms are respectively provided and evenly distributed in the circumferential direction of the bag - clamping device 717.

[0052] It can be understood that, refer to Figure 8 、 Figure 10 As shown, the operator stands on the side close to the fixed arm. By means of the first driving device and the second driving device, the swing arm 711 and the bag - clamping device 717 are rotated towards the fixed - arm direction. Manually, the bag body is hung on the hanging - bag assemblies 712 of the swing arm 711 and the fixed arm, and the bag mouth is sleeved into the bag - clamping device 717. After the bag - clamping device 717 clamps the periphery of the bag mouth, after the first driving device and the second driving device are reset, a single person can complete the processes of hanging the bag, sleeving the bag and weighing, improving the operation convenience and work efficiency.

[0053] Refer to Figure 7 As shown, a self - aligning bearing 703 is installed inside the hanging - bag frame body 701 corresponding to the end position of the swing arm 711.

The traction cross brace 24 is fixedly installed on the traction support feet 21 by bolts. The step bolt 29 passes through the electric hoist 23 and is fixed by a slotted nut 26. The traction split pin 25 is used to prevent axial and radial sliding. In order to prevent the electric hoist 23 from moving on the step bolt 29, a rubber pad 27 is inserted in the middle. In order to reduce friction, a collar 28 is inserted in the middle. During installation, the notch of the hook 22 faces forward relative to the electric hoist 23. The electric hoist 23 is operated electrically to drive the hook 22 to lift and lower, and the hook 22 is hung in the lifting ring 604.

[0066] When performing bagging and weighing, the traction mechanism 2 drives the mounting frame body 605 to slide along the column guide to the manual operation position. The rotating cylinder 705 drives the bag clamping device 717 to push forward to the limit position and then stop. The swinging cylinder 710 drives the swing arm 711 to the limit position and then stop. The operator 9 hangs the hanging rings of the ton bag 8 into the hanging bag assemblies 712 on the swing arm 711 and the fixed arm in sequence, and sets the bag mouth of the ton bag 8 on the outer periphery of the receiving pipe of the bag clamping device 717 to ensure that the bag mouth fits the receiving pipe. After completing the above operations, the operator 9 presses the control button on the tread platform 10; The rotating cylinder 705 starts, driving the receiving pipe of the bag clamping device 717 to retreat along the rotating shaft 719, and gradually resetting to a position coaxial with the blanking pipe 5; the bag clamping claws are driven by the bag clamping cylinder to clamp the periphery of the bag mouth, ensuring that the bag mouth is fixed and there is no risk of material leakage.

[0067] At the same time, the swinging cylinder 710 drives the swinging arm 711 to rotate in the opposite direction to the rear extreme position limit. The end of the swinging arm 711 lands on the swinging guide block 714 and stops. The swinging guide block 714 provides additional support for the swinging arm 711 to prevent the swinging arm 711 from sagging under the full load state; The traction mechanism 2 starts, driving the mounting frame 605 to slide upward along the column guiding system, ensuring its stable operation and gradually reaching the set blanking position.

[0068] The material enters the receiving pipe through the blanking pipe 5 and enters the inside of the ton bag 8. During the blanking process, the weighing sensor 601 real - time feedbacks the weight data. When the weight of the ton bag 8 reaches the preset value, the system stops blanking and completes the weighing process.

[0069] Refer to Figure 5 、 Figure 6 As shown, in order to avoid the sagging of the swinging arm 711 under full load, in one embodiment, a support frame 713 is further installed on the hanging bag frame 701, and the support frame 713 is installed with a swinging guide block 714 that bears the swinging of the swinging arm 711. The setting of the support frame 713 and the swinging guide block 714 avoids the sagging of the swinging arm 711 under full load and improves the load - bearing capacity of the equipment.

[0070] There are two columns, and it further includes a first guiding device and a second guiding device. The columns are connected to the steel platform 4. The mounting frame 605 includes two sliding arms, and each sliding arm is respectively slidably connected to two perpendicular surfaces of the columns through the first guiding device and the second guiding device.

[0071] The first guiding device includes a support mounting seat 606, a support bearing 607, and a bearing sleeve 608 installed on the support mounting seat 606 through the support bearing 607. Through the setting of the shaft - end elastic retaining ring, it prevents the support bearing 607 from axially moving on the support mounting seat 606; specifically, the bearing sleeve 608 contacts the flat steel on the two columns to prevent the mounting frame 605 from tilting or sagging.

[0072] An adjusting screw rod and a nut are installed on the sliding arm to adjust the position of the support mounting seat 606 on the sliding arm, and further adjust the contact gap between the bearing sleeve 608 and the flat steel.

[0073] The second guiding device includes a guiding mounting base 609, a guiding shaft 618 mounted on the guiding mounting base 609, a guiding pin shaft 610 radially penetrating through the guiding shaft 618, and a guiding bearing 611 mounted on the guiding pin shaft 610. Through the reserved screw holes on the guiding mounting base 609, radial movement of the guiding shaft 618 is prevented. Through the arrangement of an axial circlip at the shaft end, axial movement of the guiding shaft 618 is prevented. The guiding bearing 611 contacts the side surface of the column, preventing the mounting frame body 605 from tilting.

[0074] The guiding mounting base 609 is connected with an adjusting bolt connected to the guiding shaft 618 to adjust the length of the guiding shaft 618 extending out of the guiding mounting base 609, and further adjust the gap between the guiding bearing 611 and the side surface of the column.

[0075] Specifically, guiding spacer sleeves 617 are arranged between multiple support bearings 607 and between multiple guiding bearings 611; the axis of the bearing sleeve 608 is perpendicular to the axis of the guiding bearing 611.

[0076] Refer to Figure 6 As shown, the mounting frame body 605 includes a cross beam connected between two sliding arms. An induction plate 612 is arranged on the cross beam. On the side surface of one column close to the induction plate 612, (multiple) connecting frames 616 are installed. The connecting frames 616 can be angle irons. The connecting frames 616 are installed with sliding tables 615 capable of adjusting the distance relative to the side surface of the column. The sliding tables 615 can be made of sheet metal with adjusting grooves and are installed on the connecting frames 616 in cooperation with bolts; a lifting bracket 614 is installed on the sliding table 615, and a proximity sensor 613 cooperating with the induction plate 612 is installed on the lifting bracket 614. The proximity sensor 613 can be adjusted vertically, facilitating the induction of different set positions of the mounting frame body 605.

[0077] Through the above arrangement, precise induction of the set position of the mounting frame body 605 is achieved. The sliding table 615 and the lifting bracket 614 can adjust the position of the proximity sensor 613, facilitating adjustment according to on-site requirements.

[0078] Refer to Figure 11 、 Figure 12As shown, the vibrator mechanism 13 includes a base 134, an airbag 132 mounted on the base 134, a lifting platform 131 connected to the airbag 132, and a vibration motor 133 mounted at the bottom of the lifting platform 131. A convex shaft 136 is provided below the lifting platform 131, and a concave shaft 137 cooperating with the convex shaft 136 is provided on the base 134. The lifting platform 131 is embedded in the conveying mechanism 12, and the lifting platform 131 can be lifted above the conveying mechanism 12 or lowered below the conveying mechanism 12 by the action of the airbag 132.

[0079] Specifically, the vibrator mechanism 13 is installed in the middle of the steel platform 4 feet and fixed to the ground by expansion bolts. The conveying mechanism 12 (which can be a conveyor belt) is installed in the middle of the steel platform 4 feet, nested on the vibrator mechanism 13, and fixed to the ground by expansion bolts.

[0080] More specifically, the vibrator mechanism 13 is placed in the exact middle of the blanking pipe 5. The base 134 is fixedly installed on the ground by expansion screws. The airbag 132 is fixedly installed on the base 134 by bolts, and the other end of the airbag 132 is fixedly installed on the lifting platform 131 by bolts. Since the airbag 132 is a flexible connection, when lifting and lowering the lifting platform 131 up and down, guiding assistance is required. The convex shaft 136 is fixedly installed on the lifting platform 131 by bolts, and the concave shaft 137 is fixedly installed on the base 134 by bolts. When the airbag 132 jacks up the lifting platform 131, the convex shaft 136 will not exceed the stroke of the concave shaft 137 to prevent slipping out. Through the taper design of the convex shaft 136 and the concave shaft 137, it is beneficial for guiding and alignment. The vibration motor 133 and the detection sheet metal 135 are fixedly installed on the lifting platform 131 by bolts, and the proximity sensor 613 is installed on the base 134. The lifting height of the lifting platform 131 is detected by obtaining the position of the detection sheet metal 135.

[0081] The overall working process of the present invention is as follows: When a pallet 11 is output from the pallet library and stops in the exact middle of the conveying mechanism 12 above the vibrator mechanism 13, the traction mechanism 2 drives the weighing and bagging mechanism to reach the operating position. The rotating cylinder 705 drives the bag clamping device 717 to push forward to the extreme limit position. The swinging cylinder 710 drives the swinging arm 711 to stop at the front extreme limit position. The operator 9 puts the mouth of the ton bag 8 on the bag clamping device 717 and puts the hanging bag of the ton bag 8 on the hanging bag device 7. After completing the above operations, the operator 9 presses the control button on the pedal 10.

[0082] The rotating cylinder 705 drives the bag clamping device 717 to reset, making the bag clamping device 717 coaxial with the blanking pipe 5. The swinging cylinder 710 drives the swinging arm 711 to the rear extreme position and stops on the swinging guide block 714. The traction mechanism 2 drives the lifting weighing film hanging mechanism to rise to the blanking position. The arc door 307 of the feeding mechanism 3 opens to the maximum to complete the rough feeding. When the weighing sensor 601 on the weighing film hanging mechanism reaches the set weight, the traction mechanism 2 drives the weighing film hanging mechanism to move down, drops the ton bag 8 onto the pallet 11. The air bag 132 in the vibrator mechanism 13 is inflated to lift the pallet 11 away from the conveying mechanism 12, and the vibration motor 133 is turned on to vibrate and compact the materials in the ton bag 8.

[0083] The feeding mechanism 3 continues to feed. The vibrator mechanism 13 relies on the concave-convex shaft 136 to guide and fall, making the vibrator mechanism 13 lower than the conveying mechanism 12. When the weight of the ton bag is nearly reaching the set mass, the arc door 307 moves to the predetermined position, and the roller shaft 313 starts to rotate for fine feeding. When the weight of the ton bag reaches the set mass, the feeding mechanism 3 is closed.

[0084] The traction mechanism 2 drives the weighing film hanging mechanism to move down, drops the ton bag 8 onto the pallet 11. The air bag 132 in the vibrator mechanism 13 is inflated to lift the pallet 11 away from the conveying mechanism 12. The dust removal fan configured in the blanking pipe 5 stops working while the vibration motor 133 is turned on. The vibrator mechanism 13 relies on the concave-convex shaft 136 to guide and fall, and the pallet 11 falls back to the conveying mechanism 12. The hook release cylinder in the bag hanging device 7 moves to disengage the hanging of the ton bag 8 from the bag hanging device 7.

[0085] The rotating cylinder 705 drives the bag clamping device 717 to push forward to the extreme position, and the bag clamping device 717 opens to allow the operator 9 to complete tying the bag. The conveying mechanism 12 drives the pallet 11 to transport the ton bag out. The traction mechanism 2 drives the weighing film hanging mechanism to reach the operating position and wait.

[0086] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
