[0028] See also Figure 1 and Figure 2 , a flexible material bag conveying mechanism, comprising:

[0029] The conveying part includes a fixed bottom plate 1, a top cover 2, a first belt roller 3, a conveying belt 4 and a first motor 5, wherein:

[0030] An internal thread support column 15 is provided on the top of the fixed bottom plate 1, and the fixed bottom plate 1 and the top cover 2 are connected to each other by screws, and the screws are threadedly connected to the internal thread support column 15. A first motor 5 is provided on the top of the top cover 2, and the output shaft of the first motor 5 is connected to the first belt roller 3, and the first belt roller 3 is connected by transmission through a conveying belt 4;

[0031] A first belt roller 3 and a conveying belt 4, both of which are arranged between the fixed bottom plate 1 and the top cover 2;

[0032] Based on the above, the conveying part is a vertical conveyor belt. When conveying the flexible packaging bag, the flexible packaging bag is placed between the two conveyor belts 4, and the first belt roller 3 and the conveyor belt 4 are driven by the first motor 5 to move. At this time, the flexible packaging bag moves toward the direction close to the bag opening part under the drive of the two conveyor belts 4. This conveying process utilizes friction, so that the flexible packaging bag can move together with the conveyor belt 4.

[0033] like Figure 1-Figure 3 As shown, the bag opening part is arranged between the fixed bottom plate 1 and the top cover 2, and includes a hinged support frame 6, a hinged cover 7, a second belt roller 8, a bag opening belt 9, a second motor 10 and a suction block, wherein:

[0034] The hinged support frame 6 and the hinged cover 7 are connected to each other by screws and are respectively hinged to the fixed bottom plate 1 and the top cover 2. The second belt roller 8 is arranged between the hinged support frame 6 and the hinged cover 7. The upper surface of the hinged cover 7 is provided with a second motor 10. The output shaft of the second motor 10 is connected to the second belt roller 8.

[0035] The hinged support frame 6 includes a support frame bottom plate 61, and a first threaded shaft 62 and a support foot are provided at the bottom end of the support frame bottom plate 61, and the first threaded shaft 62 is connected to the fixed bottom plate 1 through a nut;

[0036] The hinged cover 7 comprises the hinged cover plate 71, the upper surface of the hinged cover plate 71 is provided with a second threaded shaft 72, the second threaded shaft 72 is connected to the top cover 2 via a nut, the hinged support frame 6 and the hinged cover 7 are connected via a bag opening belt 9, and the outer surface of the bag opening belt 9 is provided with holes;

[0037] Based on the above, the hinged support frame 6 and the hinged cover 7 are connected to each other by screws to form a bracket, and the bracket is hinged to the conveying part, that is, the angle between the bracket and the conveying part can be adjusted, and the second belt roller 8 and the bag opening belt 9 are driven to move by the second motor 10. In this process, when the flexible packaging bag is just transported to the bag opening part, it can still move with the bag opening belt 9.

[0038] like Figure 2-Figure 5 As shown, the suction block comprises a rectangular block 11, a hollow tube 12 and a hollow groove 13, wherein the rectangular blocks 11 are respectively arranged on opposite sides of the hinged support frame 6 and the hinged cover 7, and the hollow groove 13 is arranged between the rectangular blocks 11, and the bottom end of the hinged support frame 6 is provided with a hollow tube 12 interconnected with the hollow groove 13, and the outer surface of the rectangular block 11 is provided with a mounting groove 16, and the interior of the mounting groove 16 is provided with an auxiliary roller 14, and the auxiliary roller 14 is in contact with the bag opening belt 9;

[0039] Based on the above, the hollow tube 12 is interconnected with the hollow groove 13. At this time, the other end of the hollow tube 12 is interconnected with the vacuum pump, so that negative pressure is generated inside the hollow groove 13, that is, negative pressure is also generated at the holes on the surface of the bag opening belt 9. When the flexible packaging bag contacts the bag opening belt 9, it is adsorbed on its surface and moves with the bag opening belt 9. Since the distance between the bag opening parts on both sides gradually increases, the two sides of the flexible packaging bag move away from each other, achieving the bag opening effect. When the flexible packaging bag is transported to a position outside the hollow groove 13, it loses its adsorption force and falls down, and the auxiliary roller 14 plays the effect of assisting the movement of the bag opening belt 9.

[0040] In actual use of this embodiment, the angle between the bag opening part and the conveying part is adjusted by loosening the nut, that is, the maximum spacing between the suction blocks is the maximum degree of opening of the flexible packaging bag;

[0041] By placing the flexible packaging bag between the two conveyor belts 4, due to the friction between the flexible packaging bag and the conveyor belts 4, when the two conveyor belts 4 move counterclockwise and clockwise respectively, the directions of the forces applied by the two conveyor belts 4 on both sides of the flexible packaging bag are the same, that is, the flexible packaging bag is driven to move toward the direction of the bag opening;

[0042] When the flexible packaging bag is conveyed to the bag opening part, the flexible packaging bag contacts the bag opening belt 9. At this time, the bag opening belt 9 rotates under the joint action of the second motor 10 and the second belt roller 8, that is, the flexible packaging bag is driven to move in a direction away from the conveying part.

[0043] In this process, the hollow tube 12 and the vacuum pump work together to generate negative pressure inside the hollow groove 13, that is, the holes on the surface of the bag opening belt 9 are also in a negative pressure state when passing through the hollow groove 3. At this time, the two sides of the flexible packaging bag are tightly fitted with the bag opening belt 9 under the action of the negative pressure and move under the drive of the bag opening belt 9. In this process, since the spacing between the bag opening belts 9 gradually increases, that is, the spacing between the bag opening belts 9 close to the conveying part is smaller than the spacing between the bag opening belts 9 far from the conveying part, the two sides of the flexible packaging bag are pulled in opposite directions and then separated, that is, the bag opening effect is achieved, and the filling operation can be realized at this time;

[0044] After the filling operation is completed, the flexible packaging bag falls under the action of gravity. If the filled material is light enough, when the flexible packaging bag follows the bag opening belt 9 to be transported to the area outside the hollow groove 13, the adsorption force is lost, and the flexible packaging bag falls;

[0045] The device is provided with a bag opening belt 9 and a suction block, so that suction can be generated during the belt conveying process, and then a pulling force is applied to both sides of the flexible packaging bag, so that the flexible packaging bag can complete the bag opening action during the conveying process, and the belt conveying structure can be applicable to flexible packaging bags of different widths. Compared with the traditional bag opening and conveying method, the conveying part and the bag opening part are combined with each other to form a complete conveying mechanism, so that the conveying mechanism can complete the bag opening operation during the conveying of the flexible packaging bag. Therefore, there is no need to consider the problem of matching degree, so as to avoid the obstruction of the conveying and bag opening operation due to poor matching. Moreover, the conveying mechanism is applicable to flexible packaging bags of different widths, and has a wider range of application than the traditional method.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
