[0020] The following is combined with Figure 1-5 This application is described in further detail.

[0021] The embodiment of the present application discloses a packaging bag support mechanism. Figure 1-5 A packaging bag supporting mechanism includes a cart 1, and a plurality of supporting columns 2 are fixedly installed on the upper surface of the cart 1. A movable support plate 4 is movably installed on the outer surface of the support column 2. A plurality of through holes are opened on the upper surface of the movable support plate 4. The outer diameter of the support column 2 is smaller than the inner diameter of the through hole. The support column 2 and the through hole are embedded in each other. A No. 1 spring 5 is sleeved at the bottom of the outer surface of the support column 2. The two side edges of the top of the cart 1 are fixedly connected to a fixed frame 6. The upper and lower ends of the inner wall of the fixed frame 6 are symmetrically welded with a fixed rod 7. The outer surface of the two fixed rods 7 on the same side is sleeved with a movable block 8, and the bottom of the outer surface of the fixed rod 7 is sleeved with a No. 2 spring 9. A rotating support rod 10 is rotatably installed in the middle of one side of the movable block 8. A magnetic block 11 is fixed to the edge of one side of the rotating support rod 10. A separation mechanism is also provided in the middle of the top of the movable support plate 4 for separating the two magnetic blocks 11 from each other.

[0022] By placing the movable support plate 4 on the top of the support column 2, the two magnetic blocks 11 are attracted to each other, and the movable block 8 cooperates with the rotating support rod 10 to support the movable support plate 4, so that the material falls into the packaging bag along the support frame 3, and the packaging bag that continuously collects the material drives the movable support plate 4 to move downward, and at the same time pushes the movable block 8 to move along the outer surface of the fixed rod 7, so that the No. 2 spring 9 buffers and supports the movable block 8 and the movable support plate 4, so that the movable support plate 4 slides to the bottom of the support column 2, and multiple No. 1 springs 5 ​​buffer the descending movable support plate 4 again. As the material inside the packaging bag accumulates, it drives the movable support plate 4 to slowly descend to the bottom of the support column 2, reflecting the buffering and supporting effect of the No. 1 spring 5 and the No. 2 spring 9 on the movable support plate 4.

[0023] Reference Figure 2 、 Figure 4 and Figure 5 The separation mechanism includes a movable rod 12, which is symmetrically mounted in the middle of the top of the movable support plate 4. The bottom end of the movable rod 12 extends to the bottom of the movable support plate 4 and is welded with an extrusion block 13. The edge of one side of the top of the magnetic block 11 and the bottom of both sides of the extrusion block 13 are set as inclined surfaces. The two magnetic blocks 11 magnetically attract each other and the bottom of one side of the extrusion block 13 is located between the two magnetic blocks 11. The magnetic block 11 and the extrusion block 13 are coupled to each other. A connecting support plate 15 is fixedly mounted on the top of the movable rod 12. The outer surface of the movable rod 12 is located between the movable support plate 4 and the connecting support plate 15 and is sleeved with a No. 3 spring 14.

[0024] By lowering the movable support plate 4 to a certain depth, the connecting support plate 15 pushes the movable rod 12 to move under the pressure of the material, and the No. 3 spring 14 contracts, so that the extrusion block 13 slides down to separate the two magnetic blocks 11, or people press down the packaging bag to push the extrusion block 13 to move, and then the rotating support rod 10 rotates along the movable block 8 and is recovered into the fixed frame 6, which reflects the separation effect of the extrusion block 13 on the magnetic block 11.

[0025] Reference Figure 1 and Figure 2 The support frame 3 is fixedly installed on the top of the support column 2, and several fixing sleeves 16 are fixed to the edge of the outer surface of the support frame 3. The middle part of the top of the fixing sleeve 16 is threadedly connected with a fastening bolt 17. The outer surface of the fastening bolt 17 is movably installed with a limiting pressure plate 18. By arranging the packaging bag inside the support frame 3, the bag opening is placed on the upper surface of the support frame 3, and the multiple fastening bolts 17 are rotated to make the limiting pressure plate 18 movably abut against the upper surface of the support frame 3, thereby fixing the bag opening of the packaging bag on the inner wall of the support frame 3, which reflects the fixing effect of the bag opening of the packaging bag in the support frame 3.

[0026] When the bag is packed in the bag, the bag will be put into the bag container 3. The bag will be put into the bag container 3 by the support frame 3, and the bag will be put into the bag container 3 by the support frame 3. The bag will be put into the bag container 3 by the support frame 3, and the bag will be put into the bag container 3 by the support frame 3. The bag will be put into the bag container 3 by the support frame 3, and the bag will be put into the bag container 3 by the support frame 3. The connecting support plate 15 pushes the movable rod 12 to move under the pressure of the material, and contracts the No. 3 spring 14, so that the extrusion block 13 slides down to separate the two magnetic blocks 11, or people press down the packaging bag to push the extrusion block 13 to move, and then the rotating support rod 10 rotates along the movable block 8 and is recovered into the fixed frame 6, so that the movable support plate 4 continues to descend along the outer surface of the support column 2, and multiple No. 1 springs 5 ​​cushion the descending movable support plate 4 again, and as the material inside the packaging bag accumulates, the movable support plate 4 is driven to slowly descend to the bottom of the support column 2; compared with the existing technology, this solution has the effect of facilitating the packaging bag to slowly descend synchronously with the material collection, improves the support effect of the movable support plate 4 on the material in the packaging bag, and solves the problem of material falling into the packaging bag and causing damage by collision.
