The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0026] A ton bag extrusion device, as Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, includes a bag breaking assembly and a fixing assembly. The bag breaking assembly includes a second bracket 11, an expander 13, a connecting frame 22, and a fourth bracket 23. Grooves are provided around the second bracket 11, and a rotating shaft is provided in the groove. An installation groove is provided at the top of the second bracket 11. There are several expanders 13, which are installed in the groove of the second bracket 11 through a shaft pin. The end structure of the expander 13 is trapezoidal, and a groove is provided in the middle of the expander 13. There are several connecting frames 22, which are installed in the groove of the expander 13 through a shaft pin. The middle structure of the fourth bracket 23 is in a ring structure, and grooves are provided around it. The other end of the connecting frame 22 is installed in the groove of the fourth bracket 23 through a shaft pin.

[0027] As Figure 3 shown, the bag breaking assembly further includes a connecting rod 12, a bag breaker 15, and a first spring 14. The connecting rod 12 is installed in the ring structure of the fourth bracket 23 and fixed by bolts. A groove is provided at the bottom of the connecting rod 12. The bag breaker 15 is in a pyramid structure and is welded to one end of the connecting rod 12. One end of the first spring 14 is connected to one end of the connecting rod 12, and the other end is connected to the second bracket 11.

[0028] When the ton bag is placed above the bag breaking assembly, under the action of gravity, the ton bag presses the bag breaker 15, and the bag breaker 15 pierces the ton bag. Then the ton bag presses down the connecting rod 12. While the connecting rod 12 is being pressed down, the expander 13 is unfolded, and the expander 13 enlarges the hole at the bottom of the ton bag, facilitating the outflow of the materials in the ton bag and accelerating the discharging speed.

[0029] As Figure 4 shown, the fixing component includes a connecting block 18 and a second spring 19. There are several second springs 19. One end of the second spring 19 is connected to the inner side of the bottom groove of the connecting rod 12. A hole is provided inside the bottom of the connecting rod 12. One end of the connecting block 18 is connected to the second spring 19. A cylindrical convex structure is provided at one end of the block 18 close to the second spring 19. One end of the cylindrical convex structure is installed inside the groove of the connecting rod 12. The structure of the other end of the connecting block 18 is trapezoidal.

[0030] As Figure 4 shown, the fixing component further includes a moving block 16, a rotating plate 17, a third bracket 20, and a small DC motor 21. The extrusion device further includes a control module. The third bracket 20 is installed in the installation groove of the second bracket 11.

[0031] When the connecting rod 12 in the bag-breaking component is pressed down, the connecting block 18 is squeezed by the moving block 16, causing the connecting block 18 to move below the moving block 16, fixing the connecting rod 12, and keeping the expander 13 in an expanded state. After the discharging is completed, the control module starts the small DC motor 21. The small DC motor 21 drives the rotating plate 17. In the annular groove of the rotating plate 17, the moving block 16 moves. Under the action of the first spring 14, the bag-breaking component rebounds. Subsequently, the small DC motor 21 is reversed to extend the moving block 16. The fixing component fixes the connecting rod 12 to prevent the connecting rod 12 from rebounding due to the reduction in weight caused by the outflow of the material in the ton bag, and keeps the expander 13 in an expanded state until all the material flows out.

[0032] As Figure 2As shown, the extrusion device further includes a housing 1, a DC motor 6, an impeller 7, and a telescopic bag 10. The bag-breaking assembly is installed inside the housing 1. The DC motor 6 is installed on one side of the bottom of the housing 1 by bolts. There is a mounting hole on the side of the housing 1 connected to the DC motor 6. The output shaft of the DC motor 6 passes through the mounting hole. The DC motor 6 is electrically connected to the control module. One end of the impeller 7 is connected to the output end of the DC motor 6 through a coupling, and the other end is installed inside the housing 1 through a rolling bearing. The telescopic bag 10 is of an annular structure. The telescopic bag 10 wraps the bag-breaking assembly, and one end of the telescopic bag 10 is adhered to the outside of the expander 13.

[0033] When placing the ton bag on the extrusion device, the control module starts the DC motor 6 to drive the impeller 7 to take out the material from the extrusion device. When the expander 13 expands, the telescopic bag 10 is expanded together, which can prevent the powder from overflowing and reduce the generation of flying dust.

[0034] As Figure 2 As shown, the extrusion device further includes a cylinder 8 and an extrusion plate 9. There are several cylinders 8, which are installed on the housing 1 by bolts. The extrusion plate 9 is installed on the output end of the cylinder 8 by bolts. The cylinder 8 is electrically connected to the control module.

[0035] When the extrusion device is working, the control module controls the cylinder 8 to make the extrusion plate 9 squeeze and pat the ton bag to accelerate the outflow of the material.

[0036] As Figure 1 As shown, the extrusion device further includes a stepping motor 2, a support 1 3, a lead screw 4, and a hoisting assembly 5. The support 1 3 is welded to the housing 1. There is a groove on the top of the housing 1, and there is a mounting groove on the inner side of the top of the support 1 3. The lead screw 4 includes a slide rail, a screw rod, and a translation slide. The slide rail is installed in the mounting groove of the support 1 3 by bolts.

[0037] The ton bag can be moved into the extrusion device through the stepping motor 2, the lead screw 4, and the hoisting assembly, without manual handling by workers, reducing the labor force.

[0038] Working principle: The worker fixes the ton bag using the hook on the lifting assembly 5, and then uses the control module to move the stepping motor 2 and the lifting assembly 5 to move the ton bag into the extrusion device. Subsequently, the height of the ton bag is adjusted so that the ton bag presses on the bag-breaking assembly. The bag breaker 15 in the bag-breaking assembly pierces the ton bag. At the same time of piercing, the connecting rod 12 is pressed down, driving the expander 13 to expand the damaged part of the ton bag that has been pierced, accelerating the outflow of the material. At the same time, the cylinder 8 is activated to squeeze and beat the ton bag. The DC motor 6 drives the impeller. After the connecting rod is pressed down, the fixing assembly fixes the connecting rod. After the discharging is completed, the stepping motor 2 and the lifting assembly 5 move the ton bag out. The control module controls the rotation of the small DC motor 21 to release the connecting rod 12. Under the action of the first spring 14, the connecting rod 12 rebounds. The small DC motor 21 rotates in reverse to extend the moving block 16, waiting for the next discharging task.

[0039] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
