Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, and more specifically, to a ball valve core polishing device. Background Technology

[0002] As a core sealing component of fluid control systems, the surface roughness of the ball valve core directly affects the valve's sealing performance and service life. Traditional polishing processes mainly rely on manual hand-held operation or single-machine semi-automatic equipment, resulting in low efficiency, poor consistency, and difficulty in handling dead corners. In recent years, although various mechanical polishing solutions have emerged in the industry, most have not effectively solved the balance problem between polishing coverage, equipment cost, and automation integration.

[0003] Chinese patent (application number: CN202310228716.6) discloses a polishing device for ball valve cores. This solution uses a gravity-driven arc-shaped pendulum sensing device to vibrate, causing the fan-shaped polishing disc to swing slightly and irregularly. It expands the polishing coverage area without the need for an additional active swing motor.

[0004] However, the aforementioned traditional equipment has the following drawbacks: 1. It only supports polishing of a single valve core and is not designed with a multi-station parallel processing structure, which restricts the improvement of production efficiency; 2. After polishing, the valve core needs to be manually disassembled, which increases operation time and the risk of bumps and knocks, making it difficult to integrate into a fully automated production line. Utility Model Content

[0005] Based on this, in order to solve the problems of traditional equipment restricting production efficiency and being difficult to integrate into fully automated production lines, this utility model provides a ball valve core polishing device, the specific technical solution of which is as follows:

[0006] A ball valve core polishing device, comprising

[0007] A polishing device, comprising a frame, a material frame, and a plurality of polishing roller assemblies arranged side by side, wherein the polishing roller assemblies are disposed within the material frame, the material frame is disposed on the frame, the material frame is provided with a material outlet, and the material frame is provided with an opening and closing device for controlling the connection state of the material outlet;

[0008] A swinging device is provided, and the machine frame is mounted on the swinging device. The swinging device is used to drive the polishing device to reciprocate tilting motion.

[0009] The aforementioned ball valve core polishing equipment, by assembling multiple polishing roller assemblies arranged side-by-side within the material frame, can simultaneously accommodate and process multiple batches of ball valve cores. This significantly increases the number of cores processed per cycle, overcoming the bottleneck of limited throughput in single-roller equipment, and greatly improves overall polishing efficiency and equipment capacity, making it particularly suitable for mass production needs. A swinging device drives the entire polishing unit (including the frame, material frame, and multiple roller assemblies) in a reciprocating tilting motion. This composite motion (roller rotation + overall tilting and swaying) causes the valve cores within the material frame to undergo more complex and thorough tumbling, sliding, and mutual friction, ensuring that all parts of the valve core surface can fully and evenly contact the abrasive, thus significantly improving the uniformity and consistency of the polishing effect. After polishing, the operator or control system only needs to operate the opening and closing device to open the discharge port, without opening the material frame or removing the roller assemblies one by one, achieving rapid, centralized, and automated unloading. This ball valve core polishing equipment solves the problems of traditional equipment that restrict production efficiency and are difficult to integrate into fully automated production lines.

[0030] like Figure 1-3As shown, a ball valve core polishing device according to one embodiment of the present invention includes a polishing device 1 and a swinging device 2; the polishing device 1 includes a frame 11, a material frame 12 and a plurality of polishing roller assemblies 13 arranged side by side, the polishing roller assemblies 13 are disposed in the material frame 12, the material frame 12 is disposed on the frame 11, the material frame 12 is provided with a discharge port 4, and the material frame 12 is provided with an opening and closing device 5 for controlling the connection state of the discharge port 4; the frame 11 is disposed on the swinging device 2, and the swinging device 2 is used to drive the polishing device 1 to reciprocate tilting motion.

[0031] The aforementioned ball valve core polishing equipment, by setting multiple polishing roller assemblies 13 side by side within the material frame 12, can simultaneously accommodate and process multiple batches of ball valve cores. This significantly increases the number of valve cores processed per batch, overcomes the bottleneck of small processing capacity of single-roller equipment, and greatly improves overall polishing efficiency and equipment capacity, making it particularly suitable for mass production needs. The entire polishing device 1 (including the frame 11, material frame 12, and multiple roller assemblies) is driven by the swing device 2 to perform reciprocating tilting motion. This composite motion (roller rotation + overall tilting and swinging) causes the valve cores within the material frame 12 to undergo more complex and thorough tumbling, sliding, and mutual friction, ensuring that all parts of the valve core surface can fully and evenly contact the abrasive, thereby significantly improving the uniformity and consistency of the polishing effect. After polishing, the operator or control system only needs to operate the opening and closing device 5 to open the discharge port 4, without opening the material frame 12 or removing the roller assemblies one by one, achieving rapid, centralized, and automated unloading. This ball valve core polishing equipment solves the problems of traditional equipment restricting production efficiency and difficulty in integrating into fully automated production lines.

[0032] like Figure 4 As shown, in one embodiment, the ball valve core polishing equipment further includes a transport device 6, which is located on the side of the polishing device 1 where the discharge port 4 is located. The transport device 6 includes a transport belt 61, a support frame 62, and a hopper 63. The transport belt 61 is inclinedly arranged on the support frame 62, with one end of the transport belt 61 facing the discharge port 4, and the hopper 63 is located at the other end of the transport belt 61. The transport belt 61 passes through the hopper 63, and the hopper 63 is provided with a grid 64, which is located above the transport belt 61 and is used to intercept valve cores rolling down from the transport belt 61. Thus, the inclined conveyor belt 61 directly receives the valve core flowing out of the discharge port 4, and together with the end hopper 63, forms an integrated process of polishing → conveying → collection, seamlessly connecting to the automated production line; the grid 64 above the conveyor belt 61 is designed to intercept the rolling valve core, while allowing abrasive debris to pass through the grid and fall into the recycling device (not shown in the figure), realizing the automatic sorting of valve core and abrasive.

[0033] like Figure 1-3 As shown, in one embodiment, the polishing roller assembly 13 includes a first roller 131, a first motor 132, a first sprocket 133, a second sprocket 134, and a first chain 135. The first motor 132 is mounted on the frame 11. The frame 11 is provided with a bearing, and one end of the first roller 131 is inserted into the inner ring of the bearing. The first sprocket 133 is sleeved on one end of the first roller 131, the second sprocket 134 is sleeved on the output end of the first motor 132, and the first chain 135 is sleeved on both the first sprocket 133 and the second sprocket 134. Thus, by driving the first sprocket 133 with a single motor, and linking the second sprockets 134 of multiple rollers via the first chain 135, synchronous rotation of multiple rollers is achieved, significantly simplifying the transmission structure and reducing manufacturing costs. The sprocket and chain drive is resistant to dusty environments and is more suitable for polishing conditions than belt drives, avoiding uneven speed caused by slippage.

[0034] like Figure 1-3 As shown, in one embodiment, the swing device 2 includes a swing mechanism 21 and a mounting plate 22. The mounting plate 22 is disposed on the swing mechanism 21, and the frame 11 is disposed on the mounting plate 22. The swing mechanism 21 is used to drive the mounting plate 22 to swing. The swing mechanism 21 includes a base 211 and a plurality of telescopic components. One end of each telescopic component is connected to the base 211, and the other end of each telescopic component is connected to the mounting plate 22. Each telescopic component includes a first mounting block 212, a first cylinder 213, a second mounting block 214, a first rotating shaft 215, and a second rotating shaft 216. 16; The first mounting block 212 is disposed on the base 211. One end of the first rotating shaft 215 is inserted into the first mounting block 212 and rotatably connected to it. The other end of the first rotating shaft 215 is hinged to one end of the first cylinder 213. The second mounting block 214 is disposed at the bottom of the mounting plate 22. One end of the second rotating shaft 216 is inserted into the second mounting block 214 and rotatably connected to it. The other end of the second rotating shaft 216 is hinged to the end of the first cylinder 213 away from the first rotating shaft 215. In this way, multiple telescopic components (cylinders) work together, and the mounting plate 22 and the base 211 are hinged together by the first / second rotating shaft 216, so as to achieve independent adjustment of the tilt angle, frequency, and amplitude, adapting to different polishing process requirements.

[0035] like Figure 2As shown, in one embodiment, the opening and closing device 5 includes a second cylinder 51 and a lifting door 52. The second cylinder 51 is mounted on the material frame 12 and connected to the lifting door 52. The second cylinder 51 drives the lifting door 52 to move up and down to control the connection state of the discharge port 4. The lifting door 52 has multiple notches 7, and each notch 7 corresponds to one of the first rollers 131. In this way, the lifting door 52 has notches 7 that match the positions of the first rollers 131, so that when closed, it perfectly fits the outer contour of the rollers, ensuring the sealing of the discharge port 4 and avoiding interference between the door and the roller movement.

[0036] Working principle:

[0037] 1. Loading stage

[0038] The operator puts the valve core to be polished and the abrasive into multiple polishing roller assemblies 13 arranged side by side in proportion (as described in Embodiment 3, the first motor 132 drives the first roller 131 to rotate through the sprocket and chain); and closes the lifting door 52 type opening and closing device 5 (as described in Embodiment 5, the notch 7 of the lifting door 52 precisely matches the outer contour of the roller to ensure a seal).

[0039] 2. Polishing stage

[0040] Dual-motion superposition polishing:

[0041] Drum rotation: The first motor 132 drives the first sprocket 133, which in turn drives all the drums to rotate synchronously via the first chain 135 (Example 3), causing the valve core to tumble and rub inside the drum;

[0042] Overall tilting and swinging: Multiple telescopic components (cylinders) of the swinging device 2 extend and retract in coordination (Example 4), and push the mounting plate 22 and the frame 11 to tilt back and forth through the first / second rotating shaft 216, causing the entire polishing device 1 to swing in a wave-like manner.

[0043] 3. Discharge stage

[0044] After polishing is completed, the second cylinder 51 (Example 5) drives the lifting door 52 to descend and opens the material frame 12 discharge port 4; the swing device 2 drives the polishing device 1 to tilt slightly, and the valve core and abrasive are concentrated and poured from the discharge port 4 under the action of gravity, without the need for manual intervention to disassemble the roller.

[0045] 4. Transportation and Sorting Stage (Example 2)

[0046] The valve core falls into the inclined conveyor belt 61 and automatically slides towards the hopper 63 along the slope;

[0047] Grid 64 intercepts valve core: The grid 64 above the conveyor belt 61 allows abrasive debris to pass through for recycling, while the intercepting valve core enters the hopper 63 to achieve automatic separation.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
