DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-4 As shown, the lower hopper for conveying polyurethane sole raw liquid includes a box body 1, a discharge port 2 is provided at the bottom of the box body 1, and a pressurizing structure 3 is provided inside the box body 1;
[0024] The pressurizing structure 3 includes a pressurizing plate 4, which is movably arranged inside the box body 1. Two guide rods 5 are fixedly installed at both ends of the pressurizing plate 4. One end of the two guide rods 5 passes through the inner side of the box body 1 and is fixedly connected to the top of the annular plate 6. Two springs 7 are respectively arranged between the two sides of the top of the annular plate 6 and the two sides of the bottom of the box body 1. Two baffles 8 are symmetrically installed on both sides of the bottom of the box body 1. A rotating roller 10 is rotatably arranged between the two baffles 8. Two eccentric wheels 11 are symmetrically fixedly installed on the outside of the rotating roller 10. One end of the rotating roller 10 passes through the baffle 8 on one side and is fixedly connected to the output shaft of the motor 9.
[0025] When it is necessary to carry out the work of extracting the raw liquid, start the motor 9, the motor 9 acts on the rotating roller 10 to rotate, the rotating roller 10 rotates synchronously with the two eccentric wheels 11, the eccentric wheel 11 acts on the annular plate 6, and the annular plate 6 performs a vertical up and down reciprocating motion according to the movement of the eccentric wheel 11. When the annular plate 6 moves up, the annular plate 6 moves up synchronously with the pressure plate 4 through the guide rod 5, so that the pressure block is pulled out from the inner side of the discharge port 2, allowing the raw liquid to enter the discharge port 2 and flow out. When the spring 7 loses the effect of the eccentric wheel 11, it rebounds with the annular plate 6, so that the pressure plate 4 and then the pressure block are pressed toward the discharge port 2, so that the raw liquid above the discharge port 2 is accelerated to flow into the discharge port 2 and flow out.
[0026] In this embodiment, a pressure block is fixedly installed in the middle of the bottom of the pressure plate 4 , and the diameter of the pressure block is consistent with the inner diameter of the discharge port 2 .
[0027] The pressure block plays the role of opening and closing the discharge port 2. At the same time, the flow rate of the raw liquid above the discharge port 2 can be accelerated under the action of the eccentric wheel 11 and the spring 7.
[0028] In this embodiment, two groups of limiting plates are symmetrically installed on both sides of the bottom of the annular plate 6, and each group of limiting plates is composed of two material limiting plates.
[0029] The limiting plate plays an auxiliary limiting role on the eccentric wheel 11.
[0030] In this embodiment, a limiting structure 12 is provided on the inner side of the box body 1, and the limiting structure 12 includes a fixed plate 13, which is fixedly installed on the top of the box body 1. A threaded rod 14 is movably provided on the top of the fixed plate 13. One end of the threaded rod 14 is rotatably connected to one end of a movable rod 15. The other end of the movable rod 15 passes through the top of a connecting tube 16 and is slidably provided on the inner side of the connecting tube 16. The connecting tube 16 is fixedly installed on the top of the pressure plate 4.
[0031] When it is necessary to export the raw liquid, first rotate the threaded rod 14 so that it moves with the movable rod 15 to the appropriate position and then stops rotating. At this time, the movable rod 15 moves toward the fixed plate 13 to the innermost top of the connecting tube 16. When the pressure plate 4 moves upward under the action of the eccentric wheel 11, the connecting tube 16 moves toward the movable rod 15 synchronously. When the pressure plate 4 moves downward, the connecting tube 16 moves downward on the outside of the movable rod 15 synchronously. The threaded rod 14 cooperates with the movable rod 15 to limit and assist the connecting tube 16 and the pressure plate 4.
[0032] In this embodiment, an operating handle is fixedly mounted on the top of the threaded rod 14 , and a limiting plate is fixedly mounted on the other end of the movable rod 15 .
[0033] The limiting piece restricts one end of the movable rod 15 to be inside the connecting pipe 16 .
[0034] In this embodiment, the box body 1 is composed of a main box and two support frames, and the top of the box body 1 is set in an open state.
[0035] The support frame supports the box body 1 .
[0036] It should be noted that the utility model is a lower hopper for conveying polyurethane sole stock solution. When in use, it is placed at a site where work is required to achieve working operating conditions;
[0037] During the process, when it is necessary to carry out the work of exporting the raw liquid, the motor 9 is started, and the motor 9 acts on the rotating roller 10 to rotate, and the rotating roller 10 rotates synchronously with the two eccentric wheels 11, and the eccentric wheel 11 acts on the annular plate 6, and the annular plate 6 performs vertical up and down reciprocating motion according to the movement of the eccentric wheel 11. When the annular plate 6 moves up, the annular plate 6 moves up synchronously with the pressure plate 4 through the guide rod 5, so that the pressure block is pulled out from the inner side of the discharge port 2, so that the raw liquid enters the discharge port 2 and flows out. When the spring 7 loses the effect of the eccentric wheel 11, it rebounds with the annular plate 6, so that the pressure plate 4 and then the pressure block are pressed toward the discharge port 2, so that the raw liquid above the discharge port 2 is accelerated to flow into the discharge port 2 and flow out;
[0038] During the process, when it is necessary to export the raw liquid, first rotate the threaded rod 14 so that it moves with the movable rod 15 to the appropriate position and then stops rotating. At this time, the movable rod 15 moves toward the fixed plate 13 to the innermost top of the connecting tube 16. When the pressure plate 4 moves up under the action of the eccentric wheel 11, the connecting tube 16 moves toward the movable rod 15 synchronously. When the pressure plate 4 moves down, the connecting tube 16 moves down synchronously on the outside of the movable rod 15. The threaded rod 14 cooperates with the movable rod 15 to limit and assist the connecting tube 16 and the pressure plate 4.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
