In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be construed as a limitation to the present disclosure.

[0025] According to the specific implementation manner provided by the present disclosure, with reference to Figures 1 to 4As shown in the figure, a bulk bag packing machine is provided, including: a cylinder body 1; a lifting mechanism for driving the cylinder body 1 to move up and down in the axial direction of the cylinder body 1; a clamping mechanism 2 including two first driving devices 21 and two clamping rings 22 arranged oppositely, the first driving device 21 is connected to the cylinder body 1 and is in transmission connection with the clamping ring 22 to drive the two clamping rings 22 to approach or move away from the cylinder body 1 in the radial direction of the cylinder body 1; and a support rod mechanism 3 including two second driving devices 31 and two support rods 32 arranged oppositely, the support rods 32 are arranged outside the cylinder body 1 and extend along the axial direction of the cylinder body 1, the second driving device 31 is connected to the cylinder body 1 and is in transmission connection with the support rods 32 to drive the two support rods 32 to approach or move away from the cylinder body 1 in the radial direction of the cylinder body 1; the bulk bag packing machine includes a first working state and a second working state. In the first working state, the two support rods 32 are attached to the outer wall of the cylinder body 1, and the two clamping rings 22 move towards the cylinder body 1 to press and fit the bag mouth part of the bulk bag 7 against the cylinder body 1 and the support rods 32; in the second working state, the two clamping rings 22 move away from the cylinder body 1, the lifting mechanism drives the cylinder body 1 to move away from the bulk bag 7 in the axial direction of the cylinder body 1, and the two support rods 32 move away from the cylinder body 1 to stretch the bag mouth part of the bulk bag 7 into a straight shape.

[0026] Through the above technical solution, in the bulk bag packing machine provided by the present disclosure, the lifting mechanism is used to drive the cylinder body 1 to move up and down along the axial direction of the cylinder body 1. The clamping mechanism 2 includes two first driving devices 21 and two clamping rings 22 arranged oppositely. The first driving device 21 is used to drive the clamping ring 22 to approach or move away from the cylinder body 1 in the radial direction of the cylinder body 1. The support rod mechanism 3 includes two second driving devices 31 and two support rods 32 arranged oppositely. The second driving device 31 is used to drive the support rod 32 to approach or move away from the cylinder body 1 in the radial direction of the cylinder body 1. In this way, when it is necessary to load the bulk bag 7, the second driving device 31 is used to control the support rod 32 to move closer to the cylinder body 1 until it is attached to the outer wall of the cylinder body 1, the bulk bag 7 is sleeved outside the cylinder body 1 and the support rods 32, and then the first driving device 21 is used to control the clamping ring 22 to move closer to the cylinder body 1 to clamp the bag mouth of the bulk bag 7. At this time, the bulk bag packing machine is in the first working state, and the bag mouth of the bulk bag 7 is tightly attached to the outer wall of the cylinder body 1 to ensure the sealing effect of the bulk bag 7 during the feeding process of the packing machine and avoid the situation of material leakage; when the loading of the bulk bag 7 is completed, the lifting mechanism is used to control the cylinder body 1 to rise and separate from the bulk bag , and at the same time, the second driving device 31 is used to control the support rod 32 to move away from the cylinder body 1. Since the support rod 32 is located inside the bulk bag 7, the bag mouth can be stretched into a straight shape. At this time, the bulk bag packing machine is in the second working state, and the bag mouth is stretched into a straight shape to ensure the sealing effect between the bulk bag 7 after the feeding is completed and before the next process.

[0027] In the bulk bag packing machine provided by the present disclosure, the packing machine can further fit the bag mouth with the outside of the cylinder body 1 in any suitable way to improve the reliability of clamping the bag mouth. As an exemplary embodiment, refer toFigure 1 , Figure 2 and Figure 3 As shown in Figure 3 , the bulk bag packing machine includes an auxiliary mechanism 4. The auxiliary mechanism 4 may include two third driving devices 41 and two clamping arms 42 arranged oppositely. The third driving device 41 is in transmission connection with the clamping arm 42 to drive the two clamping arms 42 to approach or move away from the barrel 1. Pressing blocks 421 may be respectively formed on the two clamping arms 42. In the first working state, a gap 23 is formed between the two clamping rings 22. The clamping arm 42 moves close to the barrel 1 so that the pressing block 421 is inserted into the gap 23, and the pressing block 421 presses the mouth part of the bulk bag 7 against the clamping ring 22. In the second working state, the clamping arm 42 moves away from the barrel 1 so that the pressing block 421 withdraws from the gap 23. Specifically, when the bulk bag packing machine is in the first working state, the clamping ring 22 is attached to the outer side of the barrel 1, and the mouth of the bulk bag 7 is clamped between the clamping ring 22 and the barrel 1. At this time, there is a gap 23 between the two clamping rings 22, and the bulk bag 7 has a redundant mouth at the interval. The third driving device 41 is controlled to drive the clamping arm 42 to move towards the barrel 1 so that the pressing block 421 provided on the clamping arm 42 is inserted into the gap 23, and the clamping arm 42 can press the redundant mouth to one side and clamp it through the clamping arm 42, further improving the sealing effect of the bag mouth.

[0028] Among them, the clamping arm 42 can be arranged in any suitable way to achieve the purpose of approaching or moving away from the barrel 1, and the present disclosure does not make specific limitations thereon. As an exemplary embodiment, referring to Figure 2 as shown in Figure 2 , the third driving device 41 may be configured as a rotary motor. The clamping arm 42 may be arranged around the clamping ring 22, and one end of the clamping arm 42 may be hinged to the clamping ring 22 through a hinge shaft 43. The hinge shaft 43 extends along the axial direction of the barrel 1 and is fixedly connected to the clamping arm 42. The rotary motor may be fixedly installed on the clamping ring 22, and the output shaft of the rotary motor is in transmission connection with the hinge shaft 43. In this way, when the rotary motor works, the output shaft drives the hinge shaft 43 to rotate. One end of the clamping arm 42 is fixed to the hinge shaft 43. Therefore, the other end of the clamping arm 42 away from the hinge shaft 43 can approach or move away from the barrel 1 under the drive of the rotary motor, thereby realizing the clamping of the redundant mouth.

[0029] [[ID=!3]]On the basis of the above solution, as an exemplary embodiment, referring to Figure 3As shown in the figure, the clamping arm 42 has opposite first and second ends. The first end can be hinged to the clamping ring 22 through a hinge shaft 43. The pressing block 421 can be arranged between the first end and the second end. Wherein, the clamping arm 42 is configured to press on the ton bag 7 and the second end extends beyond the edge of the bag mouth part. That is to say, when the ton bag packaging machine is in the second working state, the second end of the clamping arm 42 approaches the cylinder body 1 under the drive of the rotating motor. At this time, the pressing block 421 on the clamping arm 42 is inserted into the gap 23, and the clamping arm 42 can press the redundant bag mouth to one side and completely press the redundant bag mouth under the clamping arm 42 to further improve the sealing effect of the bag mouth.

[0030] In the present disclosure, on the premise of ensuring that the redundant bag mouth of the ton bag 7 can be pressed under the clamping arm 42, the size of the clamping arm 42 can be designed arbitrarily according to the different calibers of the ton bag 7, and the present disclosure does not make specific restrictions on this.

[0031] In the ton bag packaging machine provided by the present disclosure, as an exemplary embodiment, refer to Figure 3 As shown in the figure, the ton bag packaging machine can include an airbag 5 and an inflation mechanism. One side of the clamping ring 22 facing the cylinder body 1 has a mounting surface 221. The airbag 5 is mounted on the mounting surface 221. The inflation mechanism is used to inflate the airbag 5. In this way, when the ton bag packaging machine is in the first working state, that is, the bag mouth of the ton bag 7 is clamped between the clamping ring 22 and the cylinder body 1. At this time, the airbag 5 is inflated through the inflation mechanism, and the airbag 5 expands to be able to provide a force towards the outer wall of the cylinder body 1 for the bag mouth and increase the friction between the ton bag 7 and the clamping ring 22, so that the bag mouth fits more tightly with the cylinder body 1, avoiding the situation that the ton bag 7 slips off the outer wall of the cylinder body 1 due to the increase in the weight of the material during the feeding process of the packaging machine. In addition, the setting of the airbag 5 can also play a certain protective role for the ton bag 7 to avoid the clamping ring 22 scratching the ton bag 7.

[0032] In the ton bag packaging machine provided by the present disclosure, the clamping ring 22 and the support rod 32 can be fixed to the cylinder body 1 in any suitable manner, and the present disclosure does not make specific restrictions on this. As an exemplary embodiment, refer to Figure 3 As shown in the figure, the ton bag packaging machine includes a mounting frame 6. The mounting frame 6 is formed with an opening 612. The cylinder body 1 passes through the opening 612 and is fixedly connected to the mounting frame 6. The first driving device 21 and the second driving device 31 are fixedly installed on the mounting frame 6. Since the first driving device 21 is in transmission connection with the clamping ring 22 and the second driving device 31 is in transmission connection with the support rod 32, in this way, the clamping ring 22 and the support rod 32 are fixed to the cylinder body 1 through the cooperation of the mounting frame 6 and the first driving device 21 and the second driving device 31.

[0033] In the ton bag packaging machine provided by the present disclosure, the mounting frame 6 can be constructed in any suitable form, and the present disclosure does not make specific restrictions on this. As an exemplary embodiment, refer toFigure 4 As shown in Figure 4 , the mounting bracket 6 may include a first mounting plate 61 and two second mounting plates 62. The first mounting plate 61 is provided with an opening 612, and the first mounting plate 61 has two opposite first ends and second ends in the first direction. The two second mounting plates 62 may be respectively connected to the first end and the second end of the first mounting plate 61, and the second mounting plates 62 may extend along the axial direction of the cylinder body 1. The two first driving devices 21 are respectively fixedly mounted on the two second mounting plates 62. The two second driving devices 31 may be mounted on the first mounting plate 61, and the two second driving devices 31 may be arranged oppositely in the second direction. In this way, the first driving device 21 and the second driving device 31 can be fixed to the cylinder body 1 through the mounting bracket 6, and the first driving device 21 and the second driving device 31 are respectively in transmission connection with the clamping ring 22 and the support rod 32. Thus, the movable connection between the clamping ring 22 and the support rod 32 and the cylinder body 1 can be realized.

[0034] In the ton bag packaging machine provided by the present disclosure, as an exemplary embodiment, referring to Figure 1 or Figure 4 As shown in Figure 4 , the support rod mechanism 3 may include two fourth driving devices 33. The two fourth driving devices 33 are respectively fixedly mounted on the first mounting plate 61 and are respectively used to drive the two second driving devices 31 to move along the axial direction of the cylinder body 1. In this way, after the ton bag packaging machine finishes discharging materials, since the lifting mechanism needs to drive the cylinder body 1 to move upward so as to separate from the ton bag 7, the cylinder body 1 drives the mounting bracket 6 and then drives the support rod 32 to move upward together. The setting of the fourth driving device 33 can drive the support rod 32 to move downward relative to the cylinder body 1, so as to ensure that at least part of the support rod 32 is located inside the ton bag 7 while the cylinder body 1 rises, and avoid the situation that the support rod 32 completely disengages from the ton bag 7 and the ton bag opening cannot be tightened into a straight shape.

[0035] In the ton bag packaging machine provided by the present disclosure, the second driving device 31 and the fourth driving device 33 can be in transmission connection with each other in any suitable manner, and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, referring to Figure 1 or Figure 4 As shown in Figure 4 , the second driving device 31 may be configured as a second cylinder, and the fourth driving device 33 may be configured as a fourth cylinder. The cylinder body of the fourth cylinder may be fixedly mounted on the first mounting plate 61. The cylinder rod of the fourth cylinder may be in transmission connection with the cylinder body of the second cylinder, and the cylinder rod of the second cylinder may be in transmission connection with the support rod 32. By driving the cylinder body of the second cylinder to move downward through the fourth cylinder, the support rod 32 can be driven to move downward. In this way, the purpose that the cylinder body 1 rises while the support rod 32 needs to remain inside the ton bag 7 can be achieved.

[0036] In the ton bag packaging machine provided by the present disclosure, the first driving device 21 can be constructed in any suitable form, and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, the first driving device 21 can be constructed as a first air cylinder. The cylinder body of the first air cylinder can be fixedly installed on the second mounting plate 62, and the cylinder rod of the first air cylinder is in transmission connection with the clamping ring 22. In this way, the first driving device 21 is fixed to the cylinder body 1 and can control the movement of the clamping ring 22 by controlling the movement of the cylinder rod in the first air cylinder, thereby realizing the control of the distance between the clamping ring 22 and the cylinder body 1.

[0037] In summary, when the ton bag packaging machine provided by the present disclosure is in use, first, the second driving device 31 is used to control the support rod 32 to approach the cylinder body 1 and fit against the outer side of the cylinder body 1. The bag mouth of the ton bag 7 is sleeved on the outer sides of the cylinder body 1 and the support rod 32. Then, the first driving device 21 is controlled to drive the clamping ring 22 to approach the cylinder body 1 to clamp the ton bag 7 between the clamping ring 22 and the cylinder body 1. The inflation mechanism is opened to inflate the airbag 5 until the airbag 5 expands to further press the bag mouth. Since a gap 23 is formed at the end parts of the two opposite clamping rings 22, the redundant bag mouth of the ton bag 7 remains at the gap 23. The third driving device 41 is controlled to drive the clamping arm 42 to move towards the cylinder body 1 so that the pressing block 421 is pressed into the gap 23, and the clamping arm 42 presses the redundant bag mouth under the clamping arm 42, finally realizing the sealing of the bag mouth of the ton bag 7. After the loading is completed, first, the third driving device 41 is used to drive the clamping arm 42 away from the cylinder body 1. Then, the second driving device 31 is used to control the support rod 32 to move radially away from the cylinder body 1 along the cylinder body 1 to expand and tighten the redundant bag mouth. The exhaust port of the airbag 5 is opened to deflate the airbag 5, and the first driving device 21 is used to drive the clamping ring 22 away from the cylinder body 1. Then, the lifting mechanism is used to control the cylinder body 1 to move away from the ton bag 7 until it is separated from the ton bag 7. At the same time, the fourth driving device 33 is used to control the support rod 32 to move along the axial direction of the cylinder body 1 away from the cylinder body 1 towards the ton bag 7 to ensure that the support rod 32 is at least partially located inside the ton bag 7. Finally, the support rod 32 can tighten the bag mouth of the ton bag 7 into a straight line, achieving the purpose of ensuring the sealing effect of the ton bag 7 after the loading is completed.

[0038] In some other embodiments, the first driving device, the second driving device, and the fourth driving device can also be constructed as motors, electric cylinders, or drivers, etc., and the present disclosure does not make specific limitations thereto.
