[0004] The object of the present invention is to provide an automatic powder bulk bag packaging machine to solve the problems raised in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an automatic powder bulk bag packaging machine, comprising:

[0006] The material storage tower is used to store powder materials. The bottom of the material storage tower is connected to a discharge pipe with a valve;

[0007] The support frame is fixedly connected to the outer periphery of the storage tower. A plurality of hydraulic rods for providing power for the upward and downward movement of the ton bag are embedded in the bottom of the support frame. The moving part of the hydraulic rod is connected to a pressure sensor.

[0008] A connection frame is arranged below the support frame and is connected and fixed to the bottom end of the measuring part of the pressure sensor;

[0009] Four servo motors are installed at the bottom of the connection frame. The output shaft of the servo motor is connected to an L-shaped connecting rod, and an arc rod is welded on the side of the connecting rod;

[0010] Four connecting blocks are welded at the bottom of the connecting frame and correspond to the position of the servo motor. Two inclined limit frames for the arc rod to pass through are welded at the bottom of the connecting block. The two inclined limit frames are symmetrically arranged about the connecting block. After the arc rod is rotated, it is used to pass through the handle of the ton bag.

[0011] As a preferred embodiment, the support frame comprises:

[0012] An assembly frame, connected and fixed with a plurality of hydraulic rods;

[0013] Multiple fixed diagonal connecting plates are welded on the outside of the storage tower;

[0014] A plurality of movable oblique connecting plates are respectively arranged on one side of a plurality of fixed oblique connecting plates, and the movable oblique connecting plates are detachably connected to the fixed oblique connecting plates through two fixing bolts.

[0015] As a preferred embodiment, the movable oblique connecting plate is connected and fixed to the assembly frame via an oblique connecting rod.

[0016] As a preferred implementation scheme, a plurality of auxiliary frames are installed at the bottom end of the assembly frame of the support frame, dust-resistant fans and filter frames are installed on the inner walls of the auxiliary frames, and dust-proof nets are connected to the inner walls of the filter frames.

[0017] As a preferred embodiment, a dust filter bag is detachably connected to one side of the auxiliary frame, and an auxiliary rod is connected to the top of the auxiliary frame.

[0018] As a preferred embodiment, a draw rope is tied to the outer periphery of the auxiliary rod, and the draw rope is tied to the outer periphery of the dust filter bag.

[0024] When the automatic powder bulk bag packaging machine is in use, the arc rod can hook the handle of the bulk bag, and the two inclined limit frames can not only ensure the stability of the arc rod, but also limit the handle of the bulk bag to prevent the handle from being separated from the arc rod when the bulk bag touches the ground. When it is necessary to release the machine, the servo motor drives the connecting rod to rotate, and then drives the arc rod to rotate, exposing the space between the two inclined limit frames;

[0025] The automatic powder bulk bag packaging machine benefits from the operation of the dust-resistant fan, which allows the air inlet pipe to evacuate air, reducing the dust content of the air near the discharge pipe and the bulk bag, thus protecting the working environment and the staff. When the dust-resistant fan is working, the filter net can pre-filter the air, and the dust filter bag can re-filter. Regular cleaning and replacement of the dust filter bag and the receiving bag can meet the continuous work.

[0026] This automatic powder ton bag packaging machine can not only degas ton bags, greatly increasing the storage capacity, but also perform vacuum dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figures 1 to 6 , an automatic powder bulk bag packaging machine, this embodiment includes:

[0040] The storage tower 1 is used to store powder materials. The bottom of the storage tower 1 is connected to a discharge pipe 2 with a valve. The outer periphery of the storage tower 1 is installed with supporting equipment. Support measuring components and other equipment for supporting and weighing ton bags can also be installed between the supporting equipment. They are not described in detail in this application.

[0041] The support frame 3 is fixedly connected to the outer periphery of the storage tower 1. A plurality of hydraulic rods 4 for providing power for the upward and downward movement of the ton bag are embedded in the bottom end of the support frame 3. The installation method is not subject to the diagram. The stability of the hydraulic rod 4 is ensured. The moving part of the hydraulic rod 4 is connected to a pressure sensor 7. If the stability is insufficient, the pressure sensor 7 can be removed;

[0042] The connecting frame 5 is arranged below the supporting frame 3 and is connected and fixed to the bottom end of the measuring part of the pressure sensor 7. The connecting frame 5 is arranged below the discharge pipe 2. The solenoid valve of the discharge pipe 2 is opened, and the powder material in the storage tower 1 falls into the packaging bag along the discharge pipe 2. After the discharge is completed, the solenoid valve is closed, and the hydraulic rod 4 is controlled to extend and retract back and forth, so that the ton bag touches the ground intermittently, degassing the ton bag is achieved, and the compactness of the storage is ensured, which can greatly increase the storage capacity. Then, the solenoid valve of the discharge pipe 2 is opened again to discharge the material again. The above operation is repeated to meet the specified amount of powder storage;

[0043] Four servo motors 9 are installed at the bottom of the connection frame 5. The output shaft of the servo motor 9 is connected to an L-shaped connecting rod 10, and an arc rod 11 is welded to the side of the connecting rod 10;

[0044] Four connecting blocks 12 are welded to the bottom end of the connecting frame 5 and correspond to the position of the servo motor 9. Two inclined limit frames 13 for the arc rod 11 to pass through are welded to the bottom end of the connecting block 12. The two inclined limit frames 13 are symmetrically arranged about the connecting block 12. After the arc rod 11 rotates, it is used to pass through the handle of the ton bag. The handle of the ton bag is placed between the two inclined limit frames 13 of the connecting block 12. The servo motor 9 is controlled to drive the connecting rod 10 to rotate, so that the arc rod 11 passes through the handle of the ton bag and the two inclined limit frames 13. After the storage is completed, the servo motor 9 is controlled to drive the connecting rod 10 to rotate, and then drive the arc rod 11 to rotate, exposing the space between the two inclined limit frames 13, so as to take away the ton bag.

[0045] The support frame 3 comprises:

[0046] An assembly frame 31 is connected and fixed to a plurality of hydraulic rods 4;

[0047] A plurality of fixed oblique connecting plates 32 are welded to the outside of the storage tower 1;

The movable oblique connecting plates 33 are detachably connected to the fixed oblique connecting plates 32 via two fixing bolts. The movable oblique connecting plates 33 are fixedly connected to the assembly frame 31 via oblique connecting rods 34 .

[0049] In order to perform air suction and dust removal, a plurality of auxiliary frames 14 are installed at the bottom end of the assembly frame 31 of the support frame 3, and a dust-resistant fan 15 and a filter frame 16 are installed on the inner wall of the auxiliary frame 14. The inner wall of the filter frame 16 is connected to a dustproof net 17, and a dust filter bag 18 is detachably connected to one side of the auxiliary frame 14. An auxiliary rod 19 is connected to the top of the auxiliary frame 14, and a pull rope 20 is tied to the outer periphery of the auxiliary rod 19. The pull rope 20 is tied to the outer periphery of the dust filter bag 18.

The bottom end of the auxiliary frame 14 is connected to a receiving bag 23. When unloading, the dust-resistant fan 15 works to cause the air inlet pipe 22 to evacuate air, thereby reducing the dust content in the air near the discharge pipe 2 and the ton bag, thereby protecting the working environment and the staff. During this process, the filter net 17 can pre-filter the air, and the dust filter bag 18 can re-filter. Regularly cleaning and replacing the dust filter bag 18 and the receiving bag 23 can meet the continuous progress of the work.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0052] How it works

[0053] The automatic powder ton bag packaging machine uses two binding ropes 24 to bind and fix the packaging bags, puts the handle of the ton bag between the two inclined limit frames 13 of the connecting block 12, controls the servo motor 9 to drive the connecting rod 10 to rotate, so that the arc rod 11 passes through the handle of the ton bag and the two inclined limit frames 13, opens the solenoid valve of the discharge pipe 2, and the powder material in the storage tower 1 falls into the packaging bag along the discharge pipe 2. After the discharge is completed, the solenoid valve is closed, and the hydraulic rod 4 is controlled to retract back and forth, so that the ton bag intermittently touches the ground, realizes the degassing of the ton bag, ensures the compactness of the storage, and can greatly increase the storage capacity, and then opens the solenoid valve of the discharge pipe 2 to discharge again, repeats the above operation, and meets the specified amount of powder storage. After the storage is completed, the servo motor 9 is controlled to drive the connecting rod 10 to rotate, and then drives the arc rod 11 to rotate, exposing the space between the two inclined limit frames 13;

[0054] When unloading, the dust-resistant fan 15 works, so that the air inlet pipe 22 is sucked, reducing the dust content in the air near the discharge pipe 2 and the ton bag, thereby protecting the working environment and the staff. During this process, the filter 17 can pre-filter the air, and the dust filter bag 18 can re-filter. Regular cleaning and replacement of the dust filter bag 18 and the receiving bag 23 can meet the needs of continuous work.
