DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-3 A feeding structure of a woven bag packaging machine includes a bracket 1, a storage box 2 is fixedly installed on the outside of the bracket 1, an auger conveyor 3 is fixedly installed in the storage box 2, the top of the auger conveyor 3 is connected to an output port 4, and the opening of the output port 4 is located just above a quantitative box 5. The material at the bottom can be transported to the quantitative box 5 at a higher position through the auger conveyor 3;

[0020] The packaging machine body 6 is fixedly installed on the outside of the bracket 1, and the top surface of the packaging machine body 6 is connected to the quantitative box 5. The bottom end of the quantitative box 5 is rotatably connected to the revolving door 12. The rotation connection of each telescopic seat 13 is located on the same side as the rotation connection of the revolving door 12, and the retractable seat 13 can drive the connecting rod 14 to extend or shorten, thereby driving the revolving door 12 to change the rotation angle. The inner side of the quantitative box 5 is symmetrically rotatably connected to two telescopic seats 13, and each telescopic seat 13 is slidably connected to a connecting rod 14, and each connecting rod 14 is rotatably connected to the top surface of the revolving door 12. Dynamic connection, one end of each connecting rod 14 is fixedly installed with a sliding piston 20, and a spring 15 is commonly installed between the outer sides of the sliding piston 20 corresponding to the position in each telescopic seat 13. A through groove 16 is opened on the outer side of each telescopic seat 13, and a sealing piston 17 is slidably connected to each through groove 16. It is worth noting that the spring 15 can drive the connecting rod 14 to stretch toward the inside of the telescopic seat 13, thereby driving the sliding piston 20 to slide in the telescopic seat 13, and the air in the compressed telescopic seat 13 is discharged through the through groove 16;

[0021] Each telescopic seat 13 drives the through slot 16 to slide through a driving mechanism, and the driving mechanism includes a threaded rod 18. Two fixed seats are symmetrically installed on the outside of each telescopic seat 13, and the threaded rod 18 is rotatably connected between the two fixed seats. A plurality of limiting rods 19 are installed between the two fixed seats, and each threaded rod 18 is threadedly connected to the sealing piston 17, and each limiting rod 19 is slidably connected to the sealing piston 17. One end of the threaded rod 18 passes through one of the fixed seats and is installed with a knob. It is worth noting that the sealing piston 17 is limited by the limiting rod 19 so that it cannot rotate and can only move linearly. By turning the knob, the threaded rod 18 can be adjusted to rotate, thereby driving the sealing piston 17 to slide, adjusting the opening size of the through slot 16, and thereby adjusting the air circulation rate in the telescopic seat 13. When the opening becomes smaller, the air circulation slows down, and the sliding piston 20 requires greater force to drive it to slide;

[0022] A conveyor belt 11 is fixedly installed on the outside of the bracket 1, and the conveyor belt 11 is located directly below the connecting pipe 10. The bottom end of the packaging machine body 6 is connected to the connecting pipe 10, and a clamping mechanism is installed on the connecting pipe 10. The clamping mechanism includes two annular frames 8, and the two annular frames 8 are fixedly installed on the outside of the connecting pipe 10. A plurality of electric telescopic rods 9 are fixedly installed on the bottom surface of the upper annular frame 8, and a pressure plate 7 is commonly installed on the bottom ends of the plurality of electric telescopic rods 9. By starting the electric telescopic rod 9, the pressure plate 7 can be driven to fix the woven bag.

[0023] When the utility model is used, the woven bag is first placed on the conveyor belt 11 and conveyed by the conveyor belt 11. When it is conveyed to the bottom of the connecting pipe 10, the woven bag can be placed on the annular frame 8 below, and then the multiple electric telescopic rods 9 are started to drive the pressing plate 7 to press downward, thereby fixing the woven bag, and at the same time, the auger conveyor 3 is started to drive the material in the storage box 2 to be conveyed to the quantitative box 5 through the auger conveyor 3;

[0024] After the materials enter the quantitative box 5, they are piled up on the revolving door 12. When the accumulated weight gradually accumulates, it overcomes the tensile force of the multiple springs 15, and then the revolving door 12 rotates, causing the materials to fall into the packaging machine body 6 and into the woven bags. Then, the revolving door 12 rotates and resets again under the action of the spring 15, realizing the access to the materials and thus achieving the quantitative feeding of the materials.

[0025] When quantitative feeding is required for different woven bag capacities, the knob can be turned to drive the sealing piston 17 to slide through the cooperation of the threaded rod 18 and the limit rod 19, thereby adjusting the opening size of the through slot 16. When the opening of the through slot 16 is small, the escape speed of the air in the telescopic seat 13 becomes slow, and heavier materials are required to drive the sliding piston 20 to slide, so that more materials can be placed on the revolving door 12, realizing quantitative adjustment of large capacity. Conversely, the opening size of the through slot 16 is increased to realize quantitative adjustment of small capacity.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
