A valve core feeding device for ball valve production

Abstract

This utility model relates to the field of ball valve manufacturing technology and discloses a valve core feeding device for ball valve production. The device includes a feeding rack with a feeding groove at its center and an auxiliary feeding assembly on its top. Through the auxiliary feeding assembly, this device, during the continuous movement of the transmission belt, uses multiple sets of push plates to divide the ball valve cores vibrating and feeding them into the feeding groove. One ball valve core is accommodated between every two sets of push plates, allowing for intermittent feeding. Furthermore, the turning of a single ball valve core within the gap between two sets of push plates does not affect the turning correction of other ball valve cores. Simultaneously, the arrangement of several contact wheels reduces the friction experienced by the ball valve cores during vibration turning correction, ensuring the directional feeding accuracy of the ball valve cores and improving the device's performance.

Description

Technical Field

[0001] This utility model relates to the field of ball valve manufacturing technology, specifically to a valve core feeding device for ball valve production. Background Technology

[0002] Ball valves are a common type of valve, consisting of a valve body and a valve core housed within the valve body. The valve core is driven by the valve stem and rotates around the axis of the ball valve. They can be used for fluid regulation and control. During the production of ball valves, the valve body, valve core, and other components need to be assembled using equipment.

[0003] According to a public announcement (Announcement No.: CN114772243B) of a ball valve production equipment, in the above application, because the wall of the feeding trough is provided with an inclined straight surface and a limiting arc surface, when the valve core falls into the feeding trough through the elevator, the arc-shaped outer surface of the valve core abuts against the inclined straight surface in advance. With the vibration of the feeding guide rail, the valve core has a downward tendency. This tendency causes the valve core to rotate circumferentially, and then gradually makes the two port planes face the two side walls of the trough. The valve core descends and falls between the two limiting arc surfaces. At this time, the two port planes face the two side walls respectively. That is, through the setting of the feeding trough wall on the feeding guide rail, the initial orientation of the through hole can be automatically adjusted in advance to meet the needs of subsequent turntable rotation and tilting seat tilting.

[0004] However, in actual use, during the vibration pushing process of the ball valve core, the ball of the valve core experiences significant friction from the wall of the feeding trough when rotating, resulting in limited active flipping capability. This necessitates that the feeding trough itself has a considerable length to ensure the vibration feeding and flipping effect of the valve core, which to some extent reduces the feeding efficiency of the valve core. In view of this, we propose a valve core feeding device for ball valve production. Summary of the Invention

[0005] The purpose of this utility model is to provide a valve core feeding device for ball valve production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a valve core feeding device for ball valve production, comprising a feeding rack, wherein a feeding groove is provided at the center of the feeding rack, and an auxiliary feeding component is provided at the top of the feeding rack;

[0007] The auxiliary feeding assembly includes a vertical plate, which is fixedly installed on the side wall of the feeding frame. A stepper motor is fixedly installed on the side wall of the vertical plate, and a transmission roller is fixedly installed on the output end of the stepper motor. A transmission belt is connected to the outer surface of the transmission roller, and a push plate is fixedly installed on the outer surface of the transmission belt. An arc-shaped groove is formed on the side wall of the push plate, and a movable cavity is formed on the inner wall of the push plate near the arc-shaped groove. A spring is slidably installed on the inner wall of the movable cavity, and a spring is fixedly connected between the side wall of the spring and the inner wall of the movable cavity. A contact seat is movably connected to the inner wall of the spring away from the spring through a guide rod, and a contact wheel is rotatably installed inside the contact seat.

[0008] Preferably, the number of push plates is set to several groups, and the several groups of push plates are evenly distributed on the outer surface of the transmission belt, so that the continuous movement of the transmission belt can cooperate with the push plates to push the valve core entering the feeding trough at intervals.

[0009] Preferably, the arc-shaped groove is always positioned towards the valve core of the ball valve to better limit the rotation area of ​​the valve core and promote the rotation of the valve core.

[0010] Preferably, the contact wheel has an arc-shaped groove on its arc-shaped outer wall to better push the ball valve core in contact with it and prevent it from falling off.

[0011] Preferably, the movable cavity is provided with a deflection assembly, which includes a movable groove on the inner wall of the rebound plate. The movable groove is provided with guide grooves on both sides of the inner wall of the movable groove. The guide rod is disposed inside the guide groove. A round rod is fixedly installed on the side wall of the contact seat. The movable cavity is provided with shaped grooves on both sides of the inner wall. The round rod is disposed inside the shaped grooves.

[0012] Preferably, the guide groove is arc-shaped, and the arc-shaped protrusion of the guide groove faces the center side of the movable cavity to better cooperate in realizing the deflection of the contact seat.

[0013] Preferably, the groove includes a horizontal section and an inclined section. The inclined section is located on the inner side of the movable cavity so that when the contact wheel is pressed against the surface of the ball valve core, the contact seat is caused to tilt upward near the end of the contact wheel inside the movable cavity.

[0014] Compared with the prior art, this utility model provides a valve core feeding device for ball valve production, which has the following beneficial effects:

[0015] 1. This ball valve core feeding device, equipped with an auxiliary feeding component, divides the ball valve cores fed into the feeding trough by multiple sets of push plates during the continuous movement of the transmission belt. Each pair of push plates accommodates one ball valve core, enabling the ball valve cores to be fed intermittently. Furthermore, the turning of a single ball valve core in the gap between two sets of push plates will not affect the turning correction of other ball valve cores. At the same time, the setting of several contact wheels can also reduce the friction force experienced by the ball valve cores during vibration turning correction to a certain extent, ensuring the directional feeding accuracy of the ball valve cores and improving the use effect of the device.

[0016] 2. The valve core feeding device for ball valve production is equipped with a deflection component. When the contact wheel is pressed against the surface of the ball valve core, the contact seat moves towards the inside of the movable cavity. At this time, due to the guidance and restriction of the shaped groove, the round rod, the guide rod, and the guide groove, the contact seat is tilted upward near the contact wheel inside the movable cavity. This causes the contact wheel to be pushed upward when it contacts the ball valve core, reducing the friction between the ball valve core and the feeding groove. This better facilitates the ball valve core to turn and adjust its position, so as to correctly assemble the ball valve core. Attached Figure Description

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a valve core feeding device for ball valve production, including a feeding rack 1, a feeding groove 2 opened at the center of the feeding rack 1, and an auxiliary feeding assembly 3 provided on the top of the feeding rack 1. The auxiliary feeding assembly 3 includes a vertical plate 31, a stepper motor 32, a transmission roller 33, a transmission belt 34, a push plate 35, an arc groove 351, a movable cavity 352, a rebound plate 353, a spring 354, a guide rod 355, a contact seat 356, and a contact wheel 357.

[0024] In one embodiment of this utility model, the upright plate 31 is fixedly installed on the side wall of the unloading rack 1. A stepper motor 32 is fixedly installed on the side wall of the upright plate 31. A transmission roller 33 is fixedly installed at the output end of the stepper motor 32. A transmission belt 34 is connected to the outer surface of the transmission roller 33. A push plate 35 is fixedly installed on the outer surface of the transmission belt 34. An arc-shaped groove 351 is opened on the side wall of the push plate 35. An active cavity 352 is opened on the inner wall of the push plate 35 near the arc-shaped groove 351. A spring plate 353 is slidably installed on the inner wall of the active cavity 352. A spring 354 is fixedly connected between the side wall of the spring plate 353 and the inner wall of the active cavity 352. A contact seat 356 is movably connected to the inner wall of the spring plate 353 away from the spring 354 through a guide rod 355. A contact wheel 357 is rotatably installed inside the contact seat 356.

[0025] Furthermore, a support is provided at the bottom of the unloading rack 1, and one end of the unloading rack 1 is connected to the discharge port of the circular vibratory feeding mechanism, so that the circular vibratory barrel of the circular vibratory feeding mechanism containing the ball valve core can sequentially transport the ball valve core to the unloading rack 1. At the same time, the shape of the left and right side walls of the unloading groove 2 is adapted to the shape of the ball valve core, so that the ball valve core can move and be fed to one end of the unloading rack 1 with its opening facing both ends of the unloading rack 1 and its spherical surface facing one side of the groove wall of the unloading groove 2. The rotating rod of the valve core faces the bottom opening of the unloading groove 2 to regulate the posture of the valve core during feeding and ensure its stability during assembly. In addition, the end of the unloading rack 1 away from the feeding is connected to the positioning device, so that the unloading rack 1 guides the valve core that has completed the turning to fall onto the positioning device, and the valve core is assembled into the ball valve by a hydraulic device or other pushing device.

[0026] Specifically, there are two sets of transmission rollers 33, and the two sets of transmission rollers 33 are symmetrically arranged with the vertical central axis of the feeder 1 as the axis of symmetry. This allows the transmission belt 34 to be positioned on top of the feeder 1 in a parallel posture to the feeder 1. At the same time, there are several sets of push plates 35, and these push plates 35 are evenly distributed on the outer surface of the transmission belt 34. This allows the continuous movement of the transmission belt 34 to work with the push plates 35 to push the valve core that enters the feed trough 2 at intervals. In addition, the arc-shaped groove 351 is always positioned towards the valve core of the ball valve to better limit the rotation area of ​​the valve core and promote the rotation of the valve core. Furthermore, there are multiple sets of movable chambers 352, and these multiple sets of movable chambers 352 are evenly distributed in a matrix array on the inner wall of the push plate 35.

[0027] In addition, two sets of springs 354 are provided between the rebound plate 353 and the inner wall of the movable cavity 352 so that the rebound plate 353 can be reset after being compressed. At the same time, an arc-shaped groove is provided on the arc-shaped outer wall of the contact wheel 357 to better push the ball valve core in contact with it and prevent it from falling off, ensuring the stable transportation of the ball valve core. Specifically, during the continuous movement of the transmission belt 34, multiple sets of push plates 35 divide the ball valve cores fed into the unloading groove 2 by the circular vibration. One ball valve core is accommodated between every two sets of push plates 35, so that the ball valve cores can be fed at intervals. Furthermore, the turning of a single ball valve core in the gap between two sets of push plates 35 will not affect the turning correction of other ball valve cores. At the same time, the setting of several contact wheels 357 can also reduce the friction force experienced by the ball valve core when it is vibrating and turning to a certain extent, ensuring the directional feeding accuracy of the ball valve core and improving the use effect of the device.

[0028] In an embodiment of this utility model, a deflection component 4 is provided inside the movable cavity 352. The deflection component 4 includes a movable groove 41, which is formed on the inner wall of the rebound plate 353. Guide grooves 42 are formed on the inner walls of both sides of the movable groove 41. A guide rod 355 is disposed inside the guide groove 42. A round rod 43 is fixedly installed on the side wall of the contact seat 356. A U-shaped groove 44 is formed on the inner walls of the left and right sides of the movable cavity 352. The round rod 43 is disposed inside the U-shaped groove 44.

[0029] It is worth noting that the guide groove 42 is arc-shaped, and the arc-shaped protrusion of the guide groove 42 faces the center of the movable cavity 352 to better facilitate the deflection of the contact seat 356. The shaped groove 44 includes a horizontal section and an inclined section. The inclined section is set closer to the inside of the movable cavity 352 so that when the contact wheel 357 is pressed against the surface of the ball valve core, the contact seat 356 will move towards the inside of the movable cavity 352. At this time, due to the guidance and restriction of the shaped groove 44, the round rod 43, the guide rod 355, and the guide groove 42, the contact seat 356 is inclined and deflected upward near the end of the contact wheel 357 inside the movable cavity 352. This causes the contact wheel 357 to be pushed upward when it contacts the ball valve core, reducing the friction between the ball valve core and the feed groove 2, so as to better facilitate the ball valve core to turn and adjust its position, so as to correctly assemble the ball valve core.

[0030] In this invention, during use, the external circular vibratory feeding mechanism is activated to sequentially transport the ball valve cores to the unloading rack 1. Simultaneously, the stepper motor 32 is activated to work with the transmission roller 33 to drive the transmission belt 34. Multiple sets of push plates 35 divide the ball valve cores fed into the unloading groove 2 by the circular vibratory feeding mechanism. One ball valve core is accommodated between every two sets of push plates 35, so that the ball valve cores can be fed at intervals. Furthermore, the turning of a single ball valve core in the gap between two sets of push plates 35 will not affect the turning correction of other ball valve cores. When the ball valve core moves to the unloading end of the unloading rack 1, it falls onto the positioning device and is assembled into the ball valve by a hydraulic device or other pushing device, thus completing the assembly of the ball valve core.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
