Description

Technical Field

[0001] This utility model belongs to the field of valve body assembly technology and relates to a feeding mechanism for a stop valve connector. Background Technology

[0002] In the field of gate valve manufacturing, a specific gate valve connector, such as... Figure 1 As shown, the bidirectional connector body 1, which has an overall columnar structure, is designed to have an O-ring 2 fitted in the middle to ensure the sealing performance and stability of the shut-off valve during use.

[0003] Currently, the assembly of such gate valve fittings mainly relies on semi-automatic production lines. In the production process, manual labor is responsible for picking up the bidirectional fitting body 1 and precisely placing it on the assembly equipment to complete subsequent assembly steps. However, this production method has significant drawbacks. In actual production operations, it frequently occurs that the O-ring 2 is not fitted onto the bidirectional fitting body 1. Once this problem occurs, the assembled gate valve will fail to meet quality standards and become a defective product. Utility Model Content

[0004] The purpose of this utility model is to provide a gate valve connector feeding mechanism that, while maintaining the original production mode, can screen out gate valve connectors without O-rings 2, thus ensuring the assembly quality of the finished gate valve.

[0005] The objective of this utility model is achieved through the following technical solution: A gate valve connector feeding mechanism includes a platform with a detachable feeding rack. The feeding rack has a groove for placing gate valve connectors. The feeding rack is tilted at an angle between 30° and 60° to the horizontal plane, allowing the gate valve connectors placed on it to slide downwards along the groove under their own weight. The front end of the feeding rack has a bolt hole communicating with the groove. A ball screw is threaded into the bolt hole, and the steel ball of the ball screw is exposed in the groove. The position of the steel ball corresponds to the position of the O-ring on the gate valve connector, which can prevent gate valve connectors with O-rings from sliding down, but does not prevent gate valve connectors without O-rings from sliding down.

[0006] As a further improvement of one embodiment of the present utility model, the platform has an inwardly recessed storage groove, the bottom surface of which is inclined downward, so that the loading rack placed on it is inclined downward. This inclination angle can ensure that the shut-off valve connector slides stably downward along the slide groove under its own weight. A pair of spring plungers are provided on the storage platform on both sides of the storage slot. The sides of the feeding rack are provided with positioning holes for inserting one end of the spring plunger. The feeding rack is fixed on the storage platform by the cooperation of the spring plunger and the positioning hole.

[0007] As a further improvement of one embodiment of the present utility model, a stainless steel metal part is embedded in the feeding rack, and the positioning hole is formed on the metal part.

[0008] As a further improvement of one embodiment of the present utility model, the feeding rack is detachably provided with a pressure plate. Specifically, threaded holes are provided on both sides of the feeding rack, and through holes are provided at corresponding positions of the pressure plate. Bolts are screwed into the threaded holes through the through holes to realize the detachable connection between the pressure plate and the feeding rack. This connection method facilitates the installation, disassembly and replacement of the pressure plate.

[0009] A gap larger than the width of a single shut-off valve connector is left between the front end of the pressure plate and the front end of the feeding rack, making it convenient for on-site personnel to grab the shut-off valve connector at the front end of the feeding rack.

[0010] As a further improvement of one embodiment of the present invention, it further includes a substrate, on which a mounting platform and a collection box are provided. The placement platform is disposed on the mounting platform, and the collection box is located at the discharge port of the feeding rack.

[0011] As a further improvement of one embodiment of the present invention, handrails are provided on both sides of the substrate to facilitate manual handling by the valve connector feeding mechanism.

[0012] As a further improvement of one embodiment of the present utility model, the upper end surface of the mounting platform is an inclined slope, the lower end of the inclined slope has a blocking part, and a notch is provided on one side of the blocking part; the lower end surface of the shelf is attached to the inclined slope, and its front end abuts against the blocking part and covers the notch.

[0013] The above technical solution has the following beneficial effects: by using an inclined feeding rack and ball screws, it is possible to effectively screen out gate valve joints that are not fitted with O-rings, thereby improving the quality and production efficiency of the assembled gate valves.

[0025] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0026] See Figures 1-6 As shown, a gate valve connector feeding mechanism is designed to solve the problem of difficulty in quickly screening connectors without O-rings during the existing gate valve connector assembly process, thereby improving the quality of assembled products and production efficiency.

[0027] The mechanism includes a base plate 6, on which a mounting platform 7 and a collection box 8 are mounted. The mounting platform 7 is secured to the base plate 6 with bolts. The storage table 3 is mounted on the mounting platform 7 via a detachable connection structure. This detachable connection can be achieved using common methods such as bolt connection or snap-fit ​​connection, facilitating the maintenance and replacement of the storage table 3.

[0028] The storage platform 3 has a detachable feeding rack 4, which has a groove 41 for placing the shut-off valve connector. The cross-sectional shape of the groove 41 is adapted to the shape of the shut-off valve connector to ensure that the shut-off valve connector can slide stably along the groove. In use, the feeding rack 4 is placed at an angle between 30° and 60° from the horizontal plane. This angle allows the shut-off valve connector placed on it to slide down the groove 41 under its own weight. The collection box 8 is located at the discharge port of the feeding rack 4 and is used to receive the shut-off valve connector that falls from the groove 41.

[0029] To filter out stop valve connectors without O-rings 2, a bolt hole 42 communicating with a slide 41 is provided at the front end of the feeding rack 4. A ball screw 5 is threaded into the bolt hole 42, and the steel ball of the ball screw 5 is exposed in the slide 41. The position of the steel ball corresponds to the position of the O-ring 2 on the stop valve connector. When a stop valve connector with an O-ring slides down past the steel ball, the O-ring will come into contact with the steel ball, and the resistance provided by the steel ball can prevent the stop valve connector with an O-ring from sliding down. However, the stop valve connector without an O-ring does not come into contact with the steel ball (in the annular groove area on the bidirectional connector body 1), and the stop valve connector can smoothly pass through the steel ball and slide down the slide to the collection box 8.

[0030] This mechanism, through the combined use of an inclined feeding rack 4 and ball screws 5, can automatically screen out gate valve connectors without O-rings without additional power. It has a simple structure and high screening efficiency, effectively improving the quality and production efficiency of gate valve assembly products.

[0031] Specifically, the upper surface of the mounting platform 7 is an inclined slope, the inclination angle of which matches the required inclination angle of the loading rack 4, eliminating the need for additional support and adjustment structures. The lower end of the inclined slope has an integrally formed stop 71, which extends along the width of the slope and serves as a limiting element. A notch 72 is provided on one side of the blocking part 71, and the size of the notch 72 is adapted to the front end of the shelf 3. The lower end surface of the shelf 3 is attached to the inclined surface, and the front end abuts against the blocking part 71, which just covers the notch 72. The notch 72 provides operating space to prevent the two from sticking together for a long time, which would make it difficult to remove.

[0032] In this design, the platform 3 is provided with an inwardly recessed storage groove 31. The groove opening of the storage groove 31 is adapted to the bottom shape of the loading rack 4, ensuring that the loading rack 4 can be stably installed. The bottom surface of the storage groove 31 is inclined downwards, and its inclination angle is consistent with the working inclination angle required by the loading rack 4. The loading rack 4 placed in the groove can naturally tilt downwards without additional adjustment. This inclination angle can provide a stable gravitational component force for the shut-off valve connector, ensuring that the shut-off valve connector slides smoothly and stably downwards along the slide groove 41, avoiding jamming.

[0033] A pair of spring plungers 32 are symmetrically arranged on the storage platforms 3 on both sides of the storage slot 31. The spring plungers 32 can be fixed in the preset mounting holes of the storage platform 3 by threaded connection or interference fit. The feeding rack 4 has positioning holes on both sides for the insertion of the telescopic ends of the spring plungers 32. During assembly, the telescopic ends of the spring plungers 32 automatically engage with the positioning holes under the action of spring force. The tight fit between the two makes the feeding rack 4 firmly fixed on the storage platform 3. During disassembly, pressing the telescopic ends of the spring plungers 32 will disengage them from the positioning holes, realizing the quick replacement of the feeding rack 4 and facilitating the adaptation of different specifications of shut-off valve connectors.

[0034] Preferably, a stainless steel metal part 43 is embedded in the feeding rack 4. The metal part 43 is integrally formed with the feeding rack 4 through an injection molding insert process, and its surface is flush with the surface of the feeding rack 4. A positioning hole is formed on the metal part 43 corresponding to the position of the spring plunger 32. The high strength of the stainless steel material can prevent wear from the positioning hole due to long-term insertion and removal, thus extending the service life of the feeding rack 4.

[0035] In this design, a pressure plate 9 is detachably mounted on the loading rack 4. The pressure plate 9 is used to limit the movement of the shut-off valve connector within the slide 41, preventing the shut-off valve connector from slipping off. Specifically, threaded holes are spaced apart along the length of both sides of the loading rack 4. These threaded holes can be ordinary M4-M6 threaded holes. Correspondingly, a through hole adapted to the threaded hole is provided on the pressure plate 9. The diameter of the through hole is slightly larger than the diameter of the bolt shank. During assembly, the bolt passes through the through hole and is screwed into the threaded hole, achieving a detachable connection between the pressure plate 9 and the loading rack 4. This connection method facilitates the installation, disassembly, and replacement of the pressure plate 9.

[0036] There is a gap between the front end of the pressure plate 9 and the front end of the feeding rack 4. The gap size is 2-5mm larger than the width of a single shut-off valve connector. This does not affect the sliding of the connector and makes it convenient for on-site personnel to grab the shut-off valve connector at the front end of the feeding rack 4 with one hand or tools.

[0037] Handrails 10 are symmetrically fixed on both sides of the base plate 6. The handrails 10 can be fastened to the base plate 6 by welding or bolting. The handrails 10 are made of round steel or square tube bent into shape, and the surface can be treated with anti-slip treatment to facilitate the manual handling of the mechanism by the operator's hands, thereby improving the stability and safety of the handling process.

[0038] The gate valve connector feeding mechanism provided by this utility model, when used on the production line, can effectively screen out gate valve connectors without O-rings by using an inclined feeding rack and ball screws, ensuring that all gate valve connectors have O-rings during assembly, thereby improving the quality and production efficiency of the assembled gate valves.
