When it is necessary to fill the next packaging bag with materials, the driving member 18 can be used to drive the rotating shaft 15 and the spiral blade to rotate to convey materials to the packaging bag. In this way, on the one hand, if the materials in the housing 12 are caked, the caked materials can be broken by the spiral blade and conveyed to the packaging bag, avoiding the problem of inconvenient discharging caused by blockage. On the other hand, by opening and closing the driving member to respectively realize the conveying and stopping of materials, there is no need to additionally set a valve, and it is also possible to avoid the problem that the materials caked at the valve due to the large temperature difference inside and outside the valve make it difficult to open the valve, so there is no need for manual prying of the valve to solve the problem of inconvenient discharging.

[0025] Specifically, in the embodiment of the present utility model, the driving member 18 includes a motor and a speed reducer drivingly connected to the motor.

[0038] With the above arrangement, the limiting member 28 can limit the top end of the packaging bag to prevent the packaging bag from detaching from the hook.

[0039] Specifically, in the embodiment of the present utility model, by pushing open the limiting member 28, the packaging bag can be hung on the hook. Under the action of the first elastic member 23, the limiting member 28 abuts against the hook 5 to limit the packaging bag.

[0043] Through the above settings, when the discharge pipe 13 feeds materials into the packaging bag, the weighing platform 4 can weigh the packaging bag and the materials inside the packaging bag. When the required weight by the technical personnel is reached, the feeding into the packaging bag can be stopped.

[0044] Preferably, in the embodiment of the present utility model, the weighing platform 4 includes a platform main body 19 located above the base and a platform scale installed at the top end of the platform main body.

[0045] Preferably, in the embodiment of the present utility model, the support frame 3 is welded to the top end of the base 1, and a material storage part 7 is installed at the top end between the support frames 3.

[0047] In the above technical solution, the platform scale is arranged below the discharge pipe 13. When it is necessary to adjust the height of the platform scale on site, the lifting member 2 can be used to drive the platform scale to lift through the platform main body 19, so as to adjust the height of the platform scale and improve the weighing accuracy of the platform scale.

[0048] Preferably, in the embodiment of the present utility model, the lifting member 2 is a hydraulic cylinder or an electric push rod.

[0049] Preferably, as Figure 1 shown, in the embodiment of the present utility model, hydraulic cylinders are installed at the four corners between the base 1 and the platform main body 19.

[0057] Through the above arrangement, the material storage part can store the material. Under the action of gravity, the material located above the discharge pipe 9 in the storage cavity can be directly discharged through the discharge pipe 9, while the material located Figure 1 on the left side of the discharge pipe 9 in can slide down into the discharge pipe 9 under the action of the guiding plate and gravity, so as to enter the packaging bag through the discharge pipe 9.

[0058] As Figure 1As shown, in the embodiment of the present utility model, the ton bag packing machine further includes a flange connection member 10. The flange connection member 10 includes a first flange, a second flange, and a plurality of locking members for detachably connecting the first flange and the second flange. The plurality of locking members are arranged at intervals along the circumferential direction of the discharge pipe 9. The first flange is connected to the discharge pipe 9 and integrally formed, and the second flange is connected to the feed pipe 11 and integrally formed. In this way, the discharge pipe 9 and the feed pipe 11 can be detachably connected, facilitating the disassembly and maintenance of the housing 12 and the components inside the housing 12.

[0059] Preferably, in the embodiment of the present utility model, the locking member is a bolt.

[0060] It should be noted that the working principle of the ton bag packing machine in the embodiment of the present utility model is as follows: The platform scale is arranged at the bottom end of the discharge pipe 13. During use, first adjust the height of the platform scale on-site according to needs, that is, start the hydraulic cylinder. The hydraulic cylinder drives the platform scale to rise and fall through the platform main body 19, so that the platform scale can be adjusted to a suitable height according to on-site needs. After adjustment, screw out the fixing member 25 from the inside of the first mounting hole and the second mounting hole 26 to make the mounting member 24 lose its fixation. After the mounting member 24 loses its fixation, slide the mounting member 24 inside the chute 27 to adjust the position of the hook, thus facilitating the hanging of different-diameter packaging bags in different places. After adjusting the hook 5 to a suitable position, screw the fixing member 25 into the first mounting hole and the second mounting hole 26 again to fix the mounting member 24 and the hook 5. After fixing the hook 5, hang the top end of the packaging bag on the hook 5, and use the limiting member 28 to limit the top end of the packaging bag to prevent the packaging bag from detaching from the hook 5. Then start the driving member 18. The driving member 18 drives the rotating shaft 15 to rotate through the elastic coupling 17. When the rotating shaft 15 rotates, the reverse spiral section 14 and the forward spiral section 16 on the rotating shaft 15 can convey the material to make the material discharge through the discharge pipe 13.

[0061] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By arranging a material conveying part between the discharge pipe and the material storage part, after the packaging bag is filled with material, the driving member can be closed to stop the rotation of the rotating shaft and the spiral blade, that is, stop conveying material to the packaging bag. And when it is necessary to fill the next packaging bag with material, the driving member can be driven to drive the rotating shaft and the spiral blade to rotate to convey material to the packaging bag. In this way, on the one hand, if material caking occurs in the housing, the caked material can be broken by the spiral blade and conveyed to the packaging bag, avoiding the problem of inconvenient discharging caused by blockage. On the other hand, by opening and closing the driving member to respectively achieve conveying and stopping the conveying of material, there is no need to additionally set a valve, and it is also possible to avoid the problem that the material cakes at the valve due to a large temperature difference inside and outside the valve, making it difficult to open the valve, thus eliminating the need for manual prying of the valve to solve the problem of inconvenient discharging.

[0062] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
