Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder shaping and production technology, specifically to an automatic control discharge valve. Background Technology

[0002] Automatic control of discharge valve technology emerged in response to the development of industrial automation and intelligence. With the expansion of diamond micron powder shaping production and the emergence of automation control requirements, the market demand for automated shaping production lines has arisen, thus placing higher demands on the automated discharge and collection of shaping machines. Traditional collection methods involve hoppers for material collection, followed by manual hopper cleaning. This method, with its numerous hoppers, is not only cumbersome but also requires machine downtime, severely impacting production efficiency and failing to meet the needs of modern industry. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic control discharge valve that achieves precise control of the valve through advanced sensors, actuators and control modules, thereby improving production efficiency and production continuity, and reducing energy consumption and labor costs.

[0004] The technical solution disclosed in this utility model is: An automatic control discharge valve includes a discharge pipe and a discharge trough. The discharge pipe is equipped with a leak-proof valve. The leak-proof valve closes or opens the discharge pipe according to a signal command, causing material to be discharged outwards. The discharged material enters the discharge trough.

[0005] As a preferred embodiment, the leak-proof valve is a telescopic structure, with its valve sealing surface located directly opposite the outlet pipe opening. When the valve sealing surface extends, it covers the outlet pipe opening, thus closing the outlet pipe.

[0006] As a preferred option, the valve sealing surface of the leak-proof valve has a step, and the size of the step is adapted to the size of the discharge pipe.

[0007] As a preferred option, the step of the leak-proof valve is a conical step.

[0008] As a preferred embodiment, the leak-proof valve is connected to an electric push rod, which drives the valve to extend or retract.

[0009] As a preferred embodiment, the electric push rod is fixed to the mounting base, the mounting base is connected to the bracket, the bracket is connected to the sleeve, and the sleeve is fitted onto the discharge pipe.

[0010] The beneficial effects of this utility model are: 1. The sealing structure effectively prevents material from getting stuck between the pipe and the valve during the closing process, thus avoiding leakage due to incomplete closure. Specifically, the valve end face has a step with a conical outer circle. When the valve is closed, this conical outer circle will press tightly against the inner wall of the discharge pipe, pushing the material adhering to the pipe wall back into the pipe. At the same time, the valve end face and the discharge pipe end face are tightly fitted, so even if a small amount of material is stuck on the end face, the stepped structure inside the discharge pipe can still effectively seal it. This double sealing mechanism ensures that there will be no leakage when the valve is closed. 2. By connecting with relevant sensors and signals, unmanned material collection and cleaning can be achieved under the command of the control system without stopping the machine. This solves the problems of discontinuous production, repetitive manual operation, and time-consuming nature of traditional selection and production. It also avoids errors such as mixing due to human error, ensuring the stability and accuracy of production. 3. High precision: Under the control of the electric push rod, the opening and closing action can be performed according to the preset time to achieve the required material cleaning speed and efficiency in production; 4. Simple structure, few vulnerable parts, and easy maintenance: The design structure is not complicated. In order to meet the needs of long-term stable production, the only vulnerable part is the electric push rod, which is easy to replace. The design has very few vulnerable parts, which makes it highly operable and adaptable to production. Attached Figure Description

[0015] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 , Figure 2In this embodiment, a sleeve 2 is fitted onto the outlet of the discharge pipe 1. Two brackets 3 are welded next to the sleeve 2. The brackets 3 are fixed to the mounting base 6. An electric push rod 4 is installed on the mounting base 6. The moving end of the electric push rod 4 is fixed to the anti-leakage valve 4. The sealing surface of the anti-leakage valve 4 is directly opposite the outlet of the discharge pipe 1. The sleeve 2 fits the entire valve mechanism onto the discharge pipe and is fixed with three screws. The extension or retraction of the electric push rod 4 drives the anti-leakage valve 4 to close or open the outlet of the discharge pipe 1.

[0016] To ensure that the upper step pushes the material inward when the valve is closed, and to prevent the valve surface from being trapped by material and causing leakage, the valve sealing surface of the leak-proof valve 4 has a conical step 4-1, the size of which is adapted to the size of the discharge pipe 1.

[0017] exist Figure 2 and Figure 3 In the closed state shown, the conical step 4-1 extends into the discharge pipe 1, pushing the material at the pipe opening inward to prevent leakage. The stepped surface of valve 4 covers the pipe opening end of the discharge pipe 1 for sealing.

[0018] The electric actuator 4 is connected to the control mechanism. Upon receiving a closing command, the electric actuator 4 extends forward, moving the leak-proof valve 4 to the closed position; upon receiving an opening command, the electric actuator 4 retracts, causing the leak-proof valve 4 to return to its original position. Figure 1 The material is allowed to flow out of the discharge pipe 1 and fall into the discharge trough 7.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
