Description

Technical Field

[0001] This invention relates to the field of plastic valve processing technology, specifically to a trimming machine for valve production. Background Technology

[0002] Plastic valves are made primarily from polymer synthetic materials and are used to control the flow rate, pressure, and direction of fluids. They are an important alternative to metal valves in industrial pipeline systems. After plastic valves are manufactured, burrs may be generated on the edges, which need to be trimmed by an edge trimming machine to ensure the quality of the valves.

[0003] Existing plastic valve trimming machines typically use a single trimming rod or disc to grind and trim the valve edges. However, a single trimming rod or disc provides poor contact with the valve edges, leading to incomplete burr removal and reduced deburring effectiveness, thus lowering the overall quality of the trimmed valve. Therefore, we propose a new trimming machine for valve production.

[0004] Combining the issues mentioned above, we find that existing trimming machines on the market cannot simultaneously avoid these problems during use. Even if they can solve them, they require external tools, thus failing to achieve the desired results. Therefore, we propose a trimming machine for valve production. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-12 The present invention provides a technical solution: a trimming machine for valve production, including a device body 1, the device body 1 including a trimming table 101, a mounting plate 102 fixedly connected to the surface of the trimming table 101, a rotary clamping assembly 103 mounted on the surface of the mounting plate 102, and a trimming mechanism 2 provided on the surface of the trimming table 101. The rotary clamping assembly 103 consists of a motor and a three-jaw chuck. When the three-jaw chuck clamps the valve, the motor can drive the three-jaw chuck to rotate, thereby driving the valve to rotate for trimming. This is prior art and will not be described in detail here. The trimming mechanism 2 includes a grinding unit 21, which is disposed on one side of the trimming table 101; The trimming mechanism 2 also includes a beveling unit 22, which is disposed on the surface of the grinding unit 21 and is used in conjunction with the grinding unit 21.

[0022] As a further limitation of the present invention, the edge grinding unit 21 includes a movable plate 2104. One side of the movable plate 2104 slides in contact with the surface of the trimming table 101. Six edge grinding rollers 2101 are arranged on one side of the movable plate 2104, arranged in pairs. A linkage ring 2115 is fixedly connected to one side of each edge grinding roller 2101. A limiting groove 2116 is formed in the inner cavity of the linkage ring 2115. A pulling rod 2114 is slidably connected to the inner cavity of the limiting groove 2116. A fixing plate 2112 is fixedly connected to the surface of the pulling rod 2114. A ball bearing 2113 is movably embedded at one end of the fixing plate 2112. A linkage groove 2117 is formed in the inner cavity of the edge grinding roller 2101. A ball bearing 2113 is slidably connected to the inner cavity of the linkage groove 2117. Two limiting plates 2118 are fixedly connected to a rotating rod 2108. A guide ring 2102 is provided on one side of the moving plate 2104. A guide hole 2109 is provided on the surface of the guide ring 2102. By providing the guide hole 2109, it can cooperate with the ball bearing 2113. When the rotating rod 2108 rotates around the guide ring 2102, the ball bearing 2113 can roll inside, thereby pulling the edge grinding roller 2101 and allowing the edge grinding roller 2101 to move back and forth. While the edge grinding roller 2101 rotates, it can move back and forth to trim the edge of the plastic valve, thereby ensuring the quality of the edge trimming of the plastic valve by the edge grinding roller 2101 and improving the trimming effect.

[0023] A gear 2107 is fixedly connected to one end of the rotating rod 2108. A triangular plate 2111 is provided on one side of the moving plate 2104. The triangular plate 2111 is rotatably sleeved on the surface of the rotating rod 2108 through a bearing. A drive motor 2103 is fixedly connected to one side of the moving plate 2104. Two electric telescopic rods 2105 are fixedly connected to one side of the mounting plate 102. The telescopic ends of the electric telescopic rods 2105 are fixedly connected to the surface of the moving plate 2104. By setting the triangular plate 2111, the rotating rod 2108 can be driven to rotate around the gear plate 2106, so that the gear 2107 can roll on the gear plate 2106, thereby driving the rotating rod 2108 to rotate. This allows the edge grinding roller 2101 to rotate and grind the edge around the valve, thereby effectively improving the edge trimming effect of the plastic valve and ensuring the quality of the edge trimming.

[0024] The output end of the drive motor 2103 extends through to one side of the moving plate 2104 and is fixedly connected to the surface of the triangular plate 2111. A gear 2106 is fixedly connected to one side of the moving plate 2104. The gear 2106 meshes with the gear 2107. Several connecting rods 2110 are fixedly connected to the surfaces of the two guide rings 2102. One end of one guide ring 2102 is fixedly connected to the surface of the moving plate 2104. By setting the connecting rods 2110, the two guide rings 2102 can be connected, thereby ensuring the stability between the guide rings 2102. This allows for stable guidance of the pull rod 2114, ensuring the stability of the reciprocating movement of the edge grinding roller 2101. This improves the edge trimming effect of the edge grinding roller 2101 on the valve and ensures the quality of the edge trimming.

[0025] The edge trimming unit 22 includes three edge trimming blades 2201. The edge trimming blades 2201 are disposed on one side of the triangle plate 2111. A support rod 2206 is fixedly connected to one side of the edge trimming blades 2201. One end of the support rod 2206 is fixedly connected to one side of the triangle plate 2111. Three long rods 2202 are disposed on one side of the triangle plate 2111. A cam 2207 is fixedly sleeved on one end of the long rod 2202. The other end of the long rod 2202 is rotatably connected to a short block 2205 through a bearing.

[0026] One end of the short block 2205 is fixedly connected to the surface of the triangular plate 2111. A connecting plate 2210 is fixedly connected to the surface of the edge trimmer 2201. A striking rod 2212 is provided on one side of the connecting plate 2210. One end of the striking rod 2212 passes through to one side of the connecting plate 2210 and is fixedly connected to a rubber striking head 2211. A spring 2209 is movably sleeved on the surface of the striking rod 2212. By setting the rubber striking head 2211, the edge trimmer 2201 can strike the position of the valve after trimming, thereby generating an instantaneous impact force to produce vibration, which can effectively remove the burrs after trimming, thereby improving the trimming effect of the valve.

[0027] One end of the spring 2209 is fixedly connected to the surface of the connecting plate 2210, and the other end of the spring 2209 is fixedly connected to the pressure plate 2208. One side of the pressure plate 2208 is fixedly connected to the surface of the striking rod 2212. The surfaces of the long rod 2202 and three of the rotating rods 2108 are all fixedly fitted with first synchronous pulleys 2204. The two first synchronous pulleys 2204 are connected by a first synchronous belt 2203 for transmission. By setting the spring 2209, the striking rod 2212 moves down when the pressure plate 2208 moves down, so that after the rubber striking head 2211 strikes the edge of the valve, it can be reset, so that the next striking can be performed. This can effectively strike and remove the burrs of the micro-connection and ensure the quality of valve trimming.

[0028] By combining the grinding unit 21 and the trimming unit 22, the purpose of effectively removing burrs from the valve edge can be achieved. When deburring the valve, the valve edge can be trimmed first by trimming, and then the valve edge can be trimmed by grinding. This allows for full contact with the burrs on the valve edge, effectively removing the burrs and improving the deburring effect. It also effectively reduces the situation of incomplete burr removal and ensures the quality of valve trimming.

[0029] The specific implementation of this embodiment is as follows: During use, the valve requiring edge trimming is placed on the three-jaw chuck on the rotary clamping assembly 103 to clamp and fix the plastic valve. After clamping, the shortening of the electric telescopic rod 2105 moves the moving plate 2104, allowing the grinding roller 2101 and the edge-cutting blade 2201 to contact the edge of the plastic valve. The drive motor 2103 drives the triangular plate 2111 to rotate. As the triangular plate 2111 rotates, it drives the edge-cutting blade 2201 to rotate around the plastic valve, thereby removing burrs from the edge of the plastic valve. Simultaneously, the rotation of the triangular plate 2111 drives the rotating rod 2... Rotating rod 2108 rotates around gear disc 2106. As rotating rod 2108 rotates around gear disc 2106, gear 2107 rolls on gear disc 2106, thereby driving rotating rod 2108 to rotate. Under the limiting action of linkage groove 2117 and limiting plate 2118, it can drive grinding roller 2101 to rotate, allowing grinding roller 2101 to grind the edge of the plastic valve after trimming by edge cutter 2201, thus performing further processing and improving the processing effect. When rotating rod 2108 rotates, it can drive the first synchronous pulley 2204 on it to rotate, thereby causing the first synchronous belt 2203 to drive the first synchronous pulley 2204 on long rod 2202 to rotate. The rotating rod 2202 rotates, causing the cam 2207 on it to rotate. The cam 2207 then presses against the pressure plate 2208, allowing the striking rod 2212 to move. This allows the rubber striking head 2211 to strike the area cut by the edge trimmer 2201, effectively removing burrs from the valve edge micro-connection after trimming, ensuring the trimming effect. As the rotating rod 2108 rotates around the gear disc 2106, the fixed plate 2112 rotates around the guide ring 2102, causing the balls 2113 to roll within the guide hole 2109. Due to the uneven design of the guide hole 2109, the balls 2113... When the internal rolling mechanism is activated, it can drive the fixed plate 2112 to move back and forth. The fixed plate 2112 drives the pull rod 2114 to move, which in turn pulls the linkage ring 2115. Since the pull rod 2114 is slidably connected in the limiting groove 2116, it will not rotate with the grinding roller 2101 when the grinding roller 2101 rotates. The pulling of the linkage ring 2115 allows the grinding roller 2101 to move back and forth on the rotating rod 2108, so that the two grinding rollers 2101 can move in opposite or relative directions. Thus, while the plastic valve edge is being trimmed by rotation, the reciprocating grinding action improves the trimming effect of the plastic valve and ensures the quality of the trimming.

[0030] Example 2: Please refer to Figures 1-12 The present invention provides a technical solution: a trimming machine for valve production. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0031] As a further limitation of the present invention, the surface of the trimming mechanism 2 is provided with a polishing mechanism 3; The polishing mechanism 3 includes three polishing rollers 301. One end of each polishing roller 301 is rotatably connected to the surface of a triangular plate 2111 via a bearing. A rotating ring 306 is fixedly sleeved on the surface of each polishing roller 301. Three extrusion rollers 305 are rotatably connected to the inner cavity of the rotating ring 306. Three conical cylinders 303 are fixedly connected to one side of the triangular plate 2111. Air blowing blades 309 are provided inside the conical cylinders 303. One end of each conical cylinder 303 is fixedly connected to an air supply pipe 308. One end of the air supply pipe 308 is fixedly connected to... There is a compression airbag 304, one end of which is fixedly connected to a conical air blowing head 315. By setting an air supply pipe 308, the air blown out by the air blowing fan blade 309 can be transported into the compression airbag 304 and finally blown out through the conical air blowing head 315. This can blow away the burrs attached to the edge of the plastic valve and make them fall off, so that the polishing roller 301 will not be affected by the attached burrs during polishing, thus ensuring the quality of polishing of the edge of the plastic valve by the polishing roller 301.

[0032] A fixing frame 314 is fixedly connected to the surface of the compression airbag 304. One end of the fixing frame 314 is fixedly connected to the surface of the conical cylinder 303. A fixing ring 307 is fixedly sleeved on the surface of the conical air head 315. One end of the fixing ring 307 is fixedly connected to the surface of the fixing frame 314. A short rod 313 is fixedly connected to one end of the air blowing fan blade 309. By setting the fixing ring 307, the conical air head 315 can be supported, thereby ensuring the stability of the conical air head 315. This allows it to effectively blow air onto the edge of the plastic valve, blowing off the burrs attached to the edge of the plastic valve after trimming. This allows the polishing roller 301 to better polish the edge of the valve, ensuring the quality of the valve after trimming.

[0033] A filter screen plate 302 is mounted on the surface of the short rod 313 via a bearing. One side of the filter screen plate 302 is fixedly connected to the surface of the conical cylinder 303. The surfaces of the short rod 313 and the three rotating rods 2108 are all fixedly mounted with second synchronous pulleys 310. The surface of the polishing roller 301 is also fixedly mounted with second synchronous pulleys 310. The surfaces of the second synchronous pulleys 310 and the third synchronous pulleys 311 are connected by a second synchronous belt 312. By setting the filter screen plate 302, the air entering the conical cylinder 303 can be filtered to prevent dust from entering the conical cylinder 303, ensuring the quality of the air blown out by the conical air blown head 315, and preventing dust and impurities from being blown onto the valve surface and affecting the polishing effect.

[0034] By setting the polishing mechanism 3, the smoothness of the valve edge can be improved. After removing the burrs, the valve edge can be polished again to make it smoother. This also further ensures the deburring effect of the valve edge, allowing for a more thorough removal of the burrs and improving the quality of the valve edge, thereby improving the quality of the valve after trimming.

[0035] The specific implementation of this embodiment is as follows: When the rotating rod 2108 rotates around the toothed disc 2106, the second synchronous wheel 310 on it rotates, thereby driving the second synchronous belt 312 to rotate. The second synchronous belt 312 drives the third synchronous wheel 311 to rotate, allowing the polishing roller 301 to rotate, thereby polishing the valve edge after trimming and grinding. When the polishing roller 301 rotates, the third synchronous wheel 311 drives another second synchronous belt 312 to rotate, thereby driving the second synchronous wheel 310 on the short rod 313 to rotate, allowing the air blowing fan blade 309 to rotate. When the air blowing fan blade 309 rotates, air enters the conical cylinder 303 and is transported into the air delivery pipe 308 through the conical cylinder 303. Before the air enters the air delivery pipe 308, the air passing through the conical opening of the conical cylinder 303 is accelerated by the narrowing of the conical opening, thus entering the air delivery pipe 308. The air is conveyed through pipe 308 into the compression air bladder 304 and finally blown out through the conical air head 315, thus blowing the air onto the surface of the valve edge and removing the burrs attached after trimming. Simultaneously, the rotating ring 306 on the polishing roller 301 rotates, driving the compression roller 305 to rotate. The compression roller 305 compresses the compression air bladder 304, compressing the air inside and allowing it to enter the conical air head 315 more quickly. This increases the airflow velocity, resulting in a stronger airflow from the conical air head 315, which more effectively removes the burrs attached to the valve surface after trimming. This prevents the polishing roller 301 from being affected by the burrs, ensuring the polishing effect of the polishing roller 301 on the trimmed valve edge and further improving the quality of valve trimming, thus guaranteeing the smoothness of the trimmed valve edge.
