Continuous elevators have the advantages of large conveying capacity, long conveying distance, simple structure, and convenient maintenance, and are widely used in industrial production. However, the discharge control system of existing continuous elevators is relatively complex and costly.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0026] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0027] This liquid bag discharge control system is used in continuous elevators for liquid transfer bags, such as... Figure 1 As shown, the lifting bucket 1 of the continuous elevator circulates vertically along a circular track, so that the liquid bag is lifted inside the shell of the continuous elevator under the action of the lifting bucket 1 and output from the discharge port, thus completing the unloading of the liquid bag.

[0028] The first aspect of this utility model provides a liquid bag dispensing control system. (See also...) Figures 1 to 6The system includes: a main housing 2 through which the lifting bucket 1 of the continuous elevator passes, and a discharge port 21 is provided on the main housing 2; a valve cover 22, which is located at the discharge port 21 and is rotatably connected to the main housing 2 to open or close the discharge port 21; a door opening mechanism 3, which is drivenly connected to the valve cover 22 to control the opening and closing of the valve cover 22; and a drive motor 4, whose output end is connected to the door opening mechanism 3, which drives the door opening mechanism 3 to move so that the valve cover 22 is opened or closed, and the drive motor 4 is connected to the PLC control system signal.

[0029] It should be noted that the main housing 2 is connected to the outer shell of the continuous elevator so that the lifting hopper 1 of the continuous elevator can pass through. When the valve cover 22 is open, the discharge port 21 is open, and the liquid bag is output through the discharge port 21; when the valve cover 22 is closed, the discharge port 21 is cut off, and the main housing 2 and the outer shell of the continuous elevator form a closed channel. By setting the door opening mechanism 3, in conjunction with the PLC control system, the liquid bag can be discharged at any destination during the lifting process. The liquid bag discharge control system provided by this utility model can serve as the outer shell of the continuous elevator during the liquid bag lifting process, and can also flexibly control the release of the liquid bag, with a simple structure.

[0030] For some specific embodiments, please refer to Figure 4 The bottom plate of the lifting hopper 1 is inclined, with the end near the valve cover 22 being lower than the end away from the valve cover 22, so that the liquid bag conveyed by the lifting hopper 1 slides out under the action of gravity after the valve cover 22 is opened, and the discharge is completed automatically.

[0031] In the liquid bag discharge control system of this embodiment, the valve cover 22 is connected to the main housing 2 through the rotating assembly 5. The rotating assembly 5 includes: a fixed seat 51, which is fixedly connected to the main housing 2, and multiple fixed seats 51 are spaced apart; a rotating shaft 52, which is rotatably connected to the fixed seat 51; and a connecting rod 53, whose two ends are fixedly connected to the valve cover 22 and the rotating shaft 52, respectively.

[0032] It should be noted that when the valve cover 22 is opened or closed, the valve cover 22 rotates around the rotating shaft 52 as the rotation center. Multiple fixed seats 51 are spaced apart to provide stable support for the rotating shaft 52 and at the same time prevent radial displacement when the rotating shaft 52 rotates.

[0033] In the liquid bag discharge control system of this embodiment, the door opening mechanism 3 includes: a supporting part 31, which is fixedly connected to the rotating shaft 52; and a cam 34, the wheel surface of which abuts against the supporting part 31, and the cam 34 is connected to the output end of the drive motor 4.

[0034] It should be noted that the drive motor 4 drives the cam 34 to rotate, and the movement of the door opening mechanism 3 is achieved by the change in diameter of the cam 34. When the lifting hopper 1 moves to the discharge port 21 of the designated floor, the drive motor 4 receives a signal and drives the cam 34 to rotate, so that the valve cover 22 rotates at an angle along the rotating shaft 52, the discharge port 21 opens, and the liquid bag slides out under the action of gravity.

[0035] In the liquid bag discharging control system of this embodiment, the supporting part 31 includes: a connecting seat 32, which is fixedly connected to the rotating shaft 52; a roller 33, and the wheel surface of the cam 34 abuts against the wheel surface of the roller 33.

[0036] It should be noted that the cam 34 cooperates with the roller 33 to realize the movement of the valve cover 22. The frictional resistance between the cam 34 and the roller 33 is small, and the wear on the cam 34 is also relatively small, thereby improving the flexibility and service life of the door opening mechanism 3.

[0037] In the liquid bag discharge control system of this embodiment, a connecting plate 23 is connected to the main housing 2. The connecting plate 23 is located close to the rotating component 5. Multiple sensors are fixed on the connecting plate 23. The multiple sensors are arranged at intervals along the direction away from the main housing 2 to sense the opening and closing state of the valve cover 22.

[0038] Specifically, the sensors include: a first sensor 24, which is located close to the main housing 2, and the valve cover 22 is in a closed state when it is within the sensing range of the first sensor 24; and a second sensor 25, which is in an open state when the valve cover 22 is within the sensing range of the second sensor 25.

[0039] The liquid bag discharge control system of this embodiment also includes a chute 6, which is connected to the discharge port 21 and extends away from the discharge port 21.

[0040] It should be noted that the end of the chute 6 furthest from the discharge port 21 is lower than the end closest to the discharge port 21. A receiving box for receiving liquid bags can be placed at the end of the chute 6 furthest from the discharge port 21 so that the liquid bags fall directly into the receiving box through the chute 6 to complete the unloading.

[0041] In the liquid bag discharge control system of this embodiment, an elongated hole 61 is provided on the chute 6, and a third sensor 62 is fixed at the bottom of the elongated hole 61.

[0042] It should be noted that when the liquid bag passes through the chute 6, the third sensor 62 will sense the signal of the liquid bag through the elongated hole 61, thereby confirming that the liquid bag has been successfully unloaded, and feeding back the signal of successful unloading to the control system.

[0043] In a second aspect, this utility model provides a continuous elevator. Please refer to [link / reference needed]. Figures 1 to 6The system includes a lifting hopper 1 and the aforementioned liquid bag discharge control system. Multiple liquid bag discharge control systems are arranged at intervals along the lifting path of the lifting hopper 1 and installed at the discharge positions on different floors according to the usage, thereby realizing the unloading of liquid bags on different floors.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
