[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The horizontal movement of the moving frame is realized by the bag sticking moving mechanism, thereby driving the sticking tape on the sticking roller to stick to one side of the opening of the packaging bag inside the bagging frame. The sticking side inclined surface structure of the moving frame is used to cooperate with the resetting of the moving frame, so that the non-sticking side of the packaging bag opens automatically under the action of gravity during the transfer process, thereby realizing automatic loading and opening of the packaging bag, so that the subsequent potassium chloride material can be directly put into the packaging bag, reducing the manual work of sorting the opening of the packaging bag, improving the degree of automation of the device, greatly improving the running smoothness of the overall machinery, improving the packaging efficiency, and reducing labor costs;

[0020] (2) The electric telescopic rod and the extension tube are used to further extend the length of the feed tube, so that the extension tube is extended to the inside of the packaging bag opening to achieve accurate delivery of the potassium chloride material. The dispersion component is used so that when the extension tube is extended to the inside of the packaging bag, the flip display board can be automatically unfolded in the horizontal direction, thereby further supporting the inside of the packaging bag to further promote the delivery of the potassium chloride material. Under the action of the dispersion component, the potassium chloride material dropped can be scattered in the inside of the packaging bag in a dispersed manner, reducing the conical accumulation of the material inside the packaging bag and improving the uniformity of the distribution of the material inside the packaging bag.

The end of the movable rod 405 is a retractable elastic structure. The sliding track of the movable rod 405 along the limiting guide groove 407 is a parallelogram. Both ends of the rotating shaft of the adhesion roller 11 penetrate the outside of the moving frame 9 and are rotatably connected with one end of the movable rod 405 on the same side. Gears A13 are sleeved on both ends of the adhesion roller 11. A tooth plate A14 is installed on one side of the support plate 401 above the limiting guide groove 407. When the movable rod 405 approaches the bagging assembly 3 along the limiting guide groove 407, the gear A13 and the tooth plate A14 mesh with each other to realize the rotation of the adhesion roller 11 and refurbish the tape.

[0041] The position limiting guide assembly 403 includes a straight groove 4031 formed at the top of the guide plate 402, and a long sliding rod 4032 is slidably installed inside the straight groove 4031, and an L-shaped sleeve rod 4033 is sleeved outside the long sliding rod 4032, and one end of the L-shaped sleeve rod 4033 is connected to the outer side of the top of the moving frame 9, and the L-shaped sleeve rod 4033 is slidably connected up and down along the outside of the long sliding rod 4032. Through the cooperation of the position limiting guide assembly 403, the movable rod 405, and the position limiting guide groove 407, the moving frame 9 is guaranteed to move forward and backward stably;

[0042] A splitting assembly 17 is provided on the outer side of the moving frame 9 below the adhesion roller 11, and gears B15 are installed at both ends of the splitting assembly 17, and the gear B15 is coaxially and collinearly distributed with the gear A13 on the same side, and a toothed plate B16 is installed on one side of the guide plate 402 below the limiting guide groove 407, and the toothed plate B16 is located below the toothed plate A14, when the movable rod 405 moves further away from the packaging bag along the L-shaped connecting rod 406, the toothed plate B16 and the gear B15 mesh with each other, and at the same time, the inner diameter of the gear B15 is larger than the outer diameter of the gear A13, and the length of the gear A13 is three times the length of the gear B15;

[0043] The dividing component 17 includes two rotating rings 1701 which are respectively rotatably connected to the two sides of the moving frame 9, and the rotating rings 1701 are coaxially and collinearly distributed with the moving frame 9. The outer ends of the rotating rings 1701 are connected to the gear B15. One side of the two rotating rings 1701 is commonly connected to a U-shaped rod 1702, and a dividing knife 1703 is installed on the side of the U-shaped rod 1702 close to the bagging component 3. A storage groove 1704 is opened at the bottom end of one side of the moving frame 9, and the storage groove 1704 is located below the adhesion roller 11. A magnetic block 1705 is embedded in the inner side of the storage groove 1704, and the magnetic block 1705 generates an attractive force on the U-shaped rod 1702.

[0044] In this embodiment, a batch of coated plastic woven bags are placed with their openings facing upward between the inclined frame 303 and the inclined push plate 302. The elasticity of the spring 305 is utilized to make the inclined push plate 302 push the packaging bag toward the inclined frame 303, and the electric push rod 404 is started to extend so as to push the moving frame 9 toward the bagging assembly 3, so that the movable rod 405 first slides along the upper half of the limiting guide groove 407, so that the adhesive tape wrapped around the outside of the adhesive roller 11 moves toward the packaging bag until the adhesive roller 11 is in contact with the bag. The upper part of the opening of the bag is fitted, and the electric push rod 404 is started to shorten, so that the movable rod 405 moves along the lower half of the limiting guide groove 407, so that the adhesion roller 11 drives the packaging bag to move directly below the lower material tube 22. Since the inclined surface of the moving frame 9 cooperates with the adhesion roller 11 to fix one side of the packaging bag, the bottom end of the packaging bag passes over the limiting support rod 8 due to deformation during the transfer process, and the non-adherent side of the packaging bag is affected by gravity and hangs down, so as to realize the automatic opening of the packaging bag;

[0045] When the packaging bag moves to the bottom of the feeding pipe 22, the control valve is started to accurately feed the potassium chloride material in the weighing control bucket 2 into the packaging bag. After the loading is completed, the electric push rod 404 is started to be further shortened, so that the moving frame 9 is continuously pulled backward. Since the packaging bag is loaded with materials, the packaging bag and the adhesion roller 11 are pulled. In this process, since the gear B15 approaches the tooth plate B16 and meshes with it, the gear B15 drives the rotating ring 1701 to rotate, so that the U-shaped rod 1702 is turned over along the outer edge of the adhesion roller 11, and the dividing knife 1703 is used to divide the adhesion side between the adhesion roller 11 and the packaging bag to separate the two. At this time, the U-shaped rod 1702 is turned upward to the maximum angle and abuts against the top of one side of the moving frame 9.

[0046] The conveyor belt 5 is started to transfer the packaging bag loaded with potassium chloride material, and the packaging bag is limited and guided by the limiting support rods 8 on both sides, and the top opening of the packaging bag is guided by the semi-Y-shaped guide plate 7 during the movement, so that the opening of the packaging bag is gradually tightened in the process of approaching the bag sealing machine 6, so that the opening end of the packaging bag automatically enters the interior of the bag sealing machine 6, and the bag sealing machine 6 is started to realize automatic sealing of the packaging bag, that is, the packaging operation of the potassium chloride material is realized;

[0047] Start the electric push rod 404 to extend, so that the movable rod 405 moves along the upper half of the limiting guide groove 407. During the movement, the gear B15 is separated from the tooth plate B16, so that the U-shaped rod 1702 automatically flips downward under the action of gravity, so that the U-shaped rod 1702 moves to the inside of the storage groove 1704. Due to the magnetic attraction of the magnetic block 1705, the U-shaped rod 1702 is reset and fixed. In this process, since the gear A13 approaches the tooth plate A14 and meshes, the gear A13 drives the adhesion roller 11 to rotate, and the adhesion roller 11 drives the tape roller 10 to rotate, so that the tape on the tape roller 10 covers the old tape on the adhesion roller 11, and the tape on the adhesion part of the adhesion roller 11 is refurbished to ensure the adhesion of the tape to the packaging bag.

[0048] Embodiment 2: This embodiment is different from Embodiment 1. The extension tube 18 is extended to achieve accurate delivery of potassium chloride material, and the expansion component 20 is used to support the inside of the packaging bag. The dispersion component 21 is used to achieve uniform delivery of potassium chloride material. Figure 1 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0049] A control valve is provided on the outside of the feeding tube 22, an extension tube 18 is slidably penetrated inside the feeding tube 22, and the bottom end of the extension tube 18 extends to the outside of the feeding tube 22, an electric telescopic rod 19 is installed on the bottom end of one side of the extension tube 18, and the top end of the electric telescopic rod 19 is connected to the bottom end of the weighing control bucket 2, the outside of the extension tube 18 located outside the feeding tube 22 is connected to the outside of the feeding tube 22 with an expansion component 20, and the bottom end of the extension tube 18 is provided with a dispersion component 21;

[0050] The unfolding assembly 20 includes a slide groove 2002 opened on both sides of the feed tube 22, and the inside of the slide groove 2002 is slidably connected with a sliding ring 2001, and the sliding ring 2001 is sleeved on the outside of the feed tube 22, the bottom end of the sliding ring 2001 is evenly hinged with a flip support plate 2003, the outside of the extension tube 18 is evenly hinged with a flip display plate 2004, and the bottom end of the outside of the flip display plate 2004 is hinged with one end of the flip support plate 2003, and the hinge point is far away from the rotation center of the flip display plate 2004, and the length of the slide groove 2002 is less than the slidable length of the extension tube 18;

[0051] The dispersion component 21 includes an annular groove 2101 opened at the bottom end of the extension tube 18, and the annular groove 2101 is internally slidably connected with an annular bracket 2102, and the annular bracket 2102 is rotationally connected with the extension tube 18 through the cooperation of the annular groove 2101. A plurality of fan-shaped plates 2103 are distributed in an annular shape at the bottom end of the annular bracket 2102, and the fan-shaped plates 2103 are inclined, and guide grooves 2104 are evenly opened at the bottom end of the fan-shaped plates 2103.

[0052] In this embodiment, when the packaging bag moves to the bottom of the feeding tube 22 during use, the electric telescopic rod 19 is started to extend, so that the extension tube 18 extends downward to the inside of the opening of the packaging bag, so as to accurately put the potassium chloride material into the packaging bag. At the same time, during the descent of the extension tube 18, the sliding ring 2001 slides downward along the slide groove 2002. Since the length of the slide groove 2002 is limited, as the extension tube 18 continues to descend, the position of one end of the flip support plate 2003 does not move, so that the other end of the flip support plate 2003 generates a pulling force on the outer side of the flip display plate 2004, so that the flip display plate 2004 04 is flipped upward and unfolded, so that the multiple flip display panels 2004 support the internal space of the packaging bag to ensure the support stability of the packaging bag. As the potassium chloride material falls, its falling impact hits the inclined surface of the fan-shaped plate 2103, and then the fan-shaped plate 2103 generates a lateral driving force, so that the annular bracket 2102 rotates along the annular groove 2101, so that the guide groove 2104 rotates and sprinkles the potassium chloride material into the interior of the packaging bag, so as to avoid the potassium chloride material from being accumulated in a cone shape inside the packaging bag, so that the material can evenly fill the packaging bag to ensure the stability of the packaging bag after filling.
