Whether using hydraulic or electric actuators, the enormous sliding friction between the slide gate and the material, and between the slide gate and the housing, must be overcome. This results in high power requirements, large equipment size, slow slide gate movement, and low control precision. Therefore, developing a sliding band electric control valve that can effectively solve these problems is of significant practical importance. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model discloses a sliding belt type electric control valve.

[0027] Example 1

[0028] According to the appendix Figure 1-3 As shown, it includes a guide rail 8 and a trolley unit. The trolley unit is movably mounted on the guide rail 8 and includes:

[0029] Upper idler roller 1, and upper idler roller 1 is configured in multiple groups;

[0030] The slide 3 is slidably connected to the guide rail 8, and the upper roller 1 is rotatably connected to the slide 3.

[0031] Tape 7 is installed on the carriage 3.

[0032] Furthermore, an upper connection port 12 is fixedly connected to one side of the guide rail 8, and the guide rail 8 and the upper connection port 12 together form the valve housing.

[0033] Example 2

[0034] According to the appendix Figure 1-3 As shown, it includes a guide rail 8 and a trolley unit. The trolley unit is movably mounted on the guide rail 8 and includes:

[0035] Upper idler roller 1, and upper idler roller 1 is configured in multiple groups;

[0036] The slide 3 is slidably connected to the guide rail 8, and the upper roller 1 is rotatably connected to the slide 3.

[0037] Tape 7 is installed on the carriage 3.

[0038] Furthermore, the trolley unit also includes:

[0039] Roller 2, which is disposed at the bottom of the carriage 3 and is rotatably connected to the guide rail 8;

[0040] The active roller 4 is located on one side of the carriage 3;

[0041] Driven roller 5 is located on the other side of carriage 3.

[0042] Furthermore, multiple connecting screws 6 are provided between the housing and the tape 7. The connecting screws 6 are used to connect the tape 7 to the housing. By removing the connecting screws 6 between the tape 7 and the housing, the entire trolley unit can be removed from the guide rail 8. It is small in size, light in weight, and easy to maintain.

[0043] Furthermore, a conductive rail 9 is fixedly connected to the inner side of the guide rail 8, and the conductive rail 9 is connected to the external circuit.

[0044] Furthermore, the drive roller 4 is equipped with a motor that can rotate forward and reverse, thereby driving the trolley unit to move outward or inward, thus realizing the outflow and cutting of materials. A carbon brush 10 is installed on one side of the motor, slidably connected to the conductive rail 9. The carbon brush 10 and the conductive rail 9 maintain electrical conductivity through sliding contact, ensuring a low-resistance, low-wear electrical connection during relative movement. The conductive rail 9 is typically a fixed component, while the carbon brush 10 contacts the surface of the conductive rail 9 through spring pressure, achieving dynamic current transmission.

[0045] Furthermore, two limit switches 11 are installed on the guide rail 8. The limit switches 11 are used to control the movement of the trolley unit to control the opening and closing of the valve. The rolling structure composed of the conveyor belt 7, the upper roller 1, and the carriage 3 greatly reduces the operating torque when opening and closing the valve, thereby reducing power requirements and saving energy. At the same time, the trolley unit can move quickly in the control of standard block materials, with fast action, high efficiency, sensitive response, and high control accuracy. Moreover, by removing the connecting screws 6 between the conveyor belt 7 and the housing, the entire trolley unit can be removed from the guide rail 8, making it small in size, lightweight, and easy to maintain.

[0046] Working principle:

[0047] When the valve needs to be opened, press the switch button to energize the motor of the drive roller 4 and make it rotate forward. Since the conveyor belt 7 is fixedly connected to the valve body at one point and has no relative movement with the body, guide rail 8, and material, the forward torque of the drive roller 4 drives the trolley unit to move outward on the guide rail 8. This causes the sealing structure formed by the conveyor belt 7, upper idler roller 1, and slide 3 to move outward, thereby opening the valve and allowing the material to flow out. When the trolley unit moves to the set position, it presses the outer limit switch in the limit switch 11, which de-energizes the motor and stops the trolley unit, completing the valve opening.

[0048] When the valve needs to be closed, press the switch button to energize the motor of the drive roller 4 and reverse it, which in turn drives the trolley unit to move inward, thereby driving the sealing structure composed of the conveyor belt 7, the upper idler roller 1, and the carriage 3 to move inward and cut off the material flow. When the trolley unit moves to the set position, press the inner limit switch in the limit switch 11 to de-energize the motor, thereby stopping the trolley unit and completing the valve closure.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
