Description

Technical Field

[0001] This invention relates to the field of casting grinding ball processing technology, specifically a casting grinding ball riser and gating separator. Background Technology

[0002] The processing technology for integral wear-resistant cast balls after sand shedding has traditionally relied on manual hammering to separate the cast balls from each other and from the gating system. This production process is inefficient and severely restricts the large-scale production of wear-resistant cast balls. Furthermore, the working environment for workers at this stage is poor and the labor intensity is high.

[0003] According to the roller separator for casting grinding balls described in patent number CN107932301 B, during processing, the interaction between the drive device, the first rotating shaft, the first gear, and the second gear drives the rotation of the disc and the roller, causing the integral casting balls and the gating gate inside the cylinder to collide with each other and separate successively under the action of centrifugal force, gravity, and inertia. At the same time, the grinding plate is used to grind and clean the sand, spatter, protrusions, and fractures on the surface of the casting balls. This not only mechanizes the casting ball production separation process, but also improves the grinding effect of the casting balls, increases production efficiency, and reduces the labor intensity of workers. However, during grinding, batch feeding and discharging are required, and internal iron filings need to be cleaned, resulting in low grinding efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a casting grinding ball riser separator, which solves the problems mentioned above.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a casting grinding ball riser separator, comprising a processing box, wherein a feeding channel for placing grinding balls is provided on one side of the processing box, and a polishing mechanism for processing the riser of the grinding balls and a pushing mechanism for pushing the grinding balls are respectively provided in the inner cavity of the processing box, and a separation mechanism for separating the iron filings of the grinding balls is provided on one side of the processing box;

[0006] The polishing mechanism includes a drive cylinder fixed to one side of the processing box. A support plate is fixedly connected to the top of the piston rod of the drive cylinder. A grinding wheel driven by a motor is rotatably connected to the surface of the support plate. A grinding belt is connected to the surface of the grinding wheel. The drive cylinder starts the support plate to move up and down, which drives the grinding wheel to move up and down. The distance between the grinding belt and the conveyor belt in the processing box is adjusted until the distance between the conveyor belt and the grinding belt is equal to the diameter of the grinding ball. When the grinding ball is transported between the grinding belt and the conveyor belt, the protruding sprues and risers on the surface will be ground off by the grinding belt.

[0007] The pushing mechanism includes a conveyor belt for transporting grinding balls inside the processing chamber and push cylinders fixed on both sides of the processing chamber. One end of the piston rod of each push cylinder is fixedly connected to a push plate that slides left and right inside the processing chamber to push the grinding balls. In use, grinding balls are added through the feeding channel, fall into the processing chamber, are transported by the conveyor belt, and after being guided by the lower pressure plate, fall below the grinding belt. At this time, the grinding wheel drives the grinding belt to rotate counterclockwise. The counterclockwise rotation of the conveyor belt then transports the grinding balls below the grinding belt, polishing them. After one side is polished, the push cylinder drives the left and right push plates to move intermittently, pushing the grinding balls along the grinding belt. The grinding balls continuously tumble below the grinding belt, adjusting the contact area with the grinding belt. The inverted V-gap design allows the grinding balls to tumble beneath the belt, ensuring each surface fully contacts the belt and effectively removing surface defects. After grinding, the balls are conveyed to a separation mechanism for separation. An airflow from a blower blows off the iron filings adhering to the grinding balls, preventing them from adhering. Lighter iron filings are lifted by the airflow and blown above the baffle plate. Guided by the inclined guide surface, they accumulate in the slag collection tank under the influence of the airflow. Heavier iron filings are filtered out through the mesh of the filter plate.

[0008] As a further aspect of the present invention: the inner cavity of the processing box is provided with a groove for accommodating the push plate, and four push cylinders are provided, which are arranged in pairs on both sides of the processing box in an alternating manner. The two push plates connected to the push cylinders on the left side are one below the left of the grinding ball and the other above the right of the grinding ball. The two push plates connected to the push cylinders on the right side are one above the left of the grinding ball and the other below the right of the grinding ball. By driving the push cylinders, the left and right push plates move intermittently and alternately, pushing the grinding ball to continuously roll under the grinding belt, adjusting the contact area with the grinding belt.

[0009] As a further aspect of the present invention: two grinding wheels are provided, and an adjusting wheel that contacts the grinding belt is rotatably connected at the center between the two grinding wheels. The lowest horizontal plane of the adjusting wheel is higher than the lowest horizontal plane of the grinding belt. The grinding belt is located at the two grinding wheels and forms an inverted V shape, which can prevent the grinding balls from being pushed to rub hard against the grinding belt when the push plate moves. By setting the inverted V gap, the grinding balls can roll under the grinding belt, ensuring that each surface can fully contact the grinding belt and effectively grind away the surface gates and risers.

[0010] As a further aspect of the present invention: a lower pressure plate is fixedly connected to one side of the processing box, and the lowest point of the lower pressure plate is flush with the bottom of the grinding belt. By setting the lower pressure plate, when the grinding balls are conveyed by the conveyor belt, they are guided by the lower pressure plate which is inclined to the lower right and conveyed to the bottom of the grinding belt to prevent material jamming.

[0011] As a further aspect of the present invention: the separation mechanism includes a separation box disposed on one side of the processing box, a filter plate rotatably connected to the lower part of the separation box, and a driving structure for driving the filter plate to vibrate at the top of the separation box. The filter plate is driven to vibrate by the driving structure. When the grinding balls are transported through the filter plate in the separation box, the rapid vibration filters the grinding debris from the filter plate for cleaning.

[0012] As a further aspect of the present invention: the driving mechanism includes a take-up reel that is driven to rotate on the separation box by a motor. A pull rope is connected to the surface of the take-up reel. One end of the pull rope passes through and extends into the inner cavity of the separation box. The bottom end of the pull rope is fixedly connected to the top of the filter plate. The take-up reel is driven to rotate back and forth by the motor, which causes the pull rope to tighten and loosen, and causes the filter plate to shake back and forth. The motor is a stepper motor, which can drive the filter plate to shake continuously for separation.

[0013] As a further aspect of the present invention: a blower head with an air vent facing the bottom of the filter plate is fixed at the bottom of the separation box. The blower head is connected to an external fan. A baffle plate is fixedly connected to the inner cavity of the separation box above the filter plate. A guide slope is provided on the left side of the baffle plate, and a slag collection tank is provided on the right side of the baffle plate. In use, the airflow blown out by the blower head blows off the iron filings adhering to the surface of the grinding ball, preventing them from adhering to the surface of the grinding ball. At this time, the lighter iron filings are blown up by the airflow blown out by the blower head and blown to the top of the baffle plate. After being guided by the guide slope, they are collected in the slag collection tank under the blowing of the airflow. The heavier iron filings are filtered out from the mesh in the filter plate and separated.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention adjusts the distance between the conveyor belt and the grinding belt. By setting an inverted V-shaped gap, the grinding balls can roll under the grinding belt, ensuring that each surface can fully contact the grinding belt. When the grinding balls are conveyed between the grinding belt and the conveyor belt, the protruding gates on the surface will be ground off by the grinding belt. Grinding can be carried out in one conveying, without the need to stop the machine for feeding and unloading after batch grinding is completed. The processing efficiency is higher and the grinding effect is better.

[0016] 2. In this invention, the cylinder drives the left and right push plates to move intermittently and alternately, causing the grinding balls to roll continuously below the grinding belt, thereby adjusting the contact area with the grinding belt.

[0017] 3. In this invention, the filter plate is driven to vibrate by a drive structure. When the grinding balls are transported through the filter plate in the separation box, the rapid vibration filters out the debris from the grinding plate for cleaning, which can quickly separate the debris and grinding balls.

Detailed Implementation

[0023] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] Please see Figure 1-4 The present invention provides a technical solution: a casting grinding ball riser separator, including a processing box 1, a feeding channel 2 for placing grinding balls is provided on one side of the processing box 1, a polishing mechanism for processing the riser of the grinding balls and a pushing mechanism for pushing the grinding balls are respectively provided in the inner cavity of the processing box 1, and a separation mechanism for separating the iron filings of the grinding balls is provided on one side of the processing box 1.

[0025] The polishing mechanism includes a drive cylinder 8 fixed on one side of the processing box 1. A support plate 4 is fixedly connected to the top of the piston rod of the drive cylinder 8. A grinding wheel 5 driven by a motor is rotatably connected to the surface of the support plate 4. A grinding belt 6 is connected to the surface of the grinding wheel 5. The drive cylinder 8 starts the support plate 4 to move up and down, which drives the grinding wheel 5 to move up and down. The distance between the grinding belt 6 and the conveyor belt 9 in the processing box 1 is adjusted until the distance between the conveyor belt 9 and the grinding belt 6 is equal to the diameter of the grinding ball. When the grinding ball is transported between the grinding belt 6 and the conveyor belt 9, the protruding sprue and riser on the surface will be ground off by the grinding belt 6.

[0026] The pushing mechanism includes a conveyor belt 9 for conveying grinding balls inside the processing box 1 and push cylinders 18 fixed on both sides of the processing box 1. One end of the piston rod of the push cylinder 18 is fixedly connected to a push plate 10 that slides left and right inside the processing box 1 to push the grinding balls. In use, grinding balls are added through the feeding channel 2, fall into the processing box 1, are conveyed by the conveyor belt 9, and fall below the grinding belt 6 after being guided by the lower pressure plate 20. At this time, the grinding wheel 5 drives the grinding belt 6 to rotate counterclockwise. The counterclockwise rotation of the conveyor belt 9 drives the grinding balls to be conveyed below the grinding belt 6, where they are polished. After one side is polished, the push cylinder 18 drives the left and right push plates 10 to move intermittently, pushing the grinding balls further. The grinding balls continuously tumble below the grinding belt 6, adjusting the contact area with the grinding belt 6. Through the setting of the inverted V gap, the grinding balls can tumble below the grinding belt 6, ensuring that each surface can fully contact the grinding belt 6, effectively grinding away the surface gating gates. After grinding, they are conveyed to the separation mechanism for separation. The separation mechanism blows air out through the blower head 12 to blow off the iron filings adhering to the surface of the grinding balls, preventing them from adhering to the surface of the grinding balls. At this time, the lighter iron filings are blown up by the airflow from the blower head 12 and blown to the top of the baffle plate 15. After being guided by the guide slope 16, they are collected in the slag collection tank 17 under the blowing of the airflow. The heavier iron filings are filtered out through the mesh in the filter plate 11 for separation.

[0027] The inner cavity of the processing box 1 is provided with a groove 19 for accommodating the push plate 10. Four push cylinders 18 are provided, and they are arranged in pairs on both sides of the processing box 1, alternating vertically. The two push plates 10 connected to the push cylinders 18 on the left side are one below the left of the grinding ball and the other above the right of the grinding ball. The two push plates 10 connected to the push cylinders 18 on the right side are one above the left of the grinding ball and the other below the right of the grinding ball. By driving the push cylinders 18, the left and right push plates 10 are moved intermittently and alternately, which pushes the grinding ball to roll continuously under the grinding belt 6, adjusting the contact area with the grinding belt 6.

[0028] There are two grinding wheels 5, and an adjusting wheel 7 that contacts the grinding belt 6 is rotatably connected at the center between the two grinding wheels 5. The lowest horizontal plane of the adjusting wheel 7 is higher than the lowest horizontal plane of the grinding belt 6. The grinding belt 6 is located at the two grinding wheels 5 and forms an inverted V shape, which can prevent the grinding ball from being pushed to rub hard against the grinding belt 6 when the push plate 10 moves. By setting the inverted V gap, the grinding ball can roll under the grinding belt 6, ensuring that each surface can fully contact the grinding belt 6, effectively grinding away the surface gates and risers.

[0029] A lower pressure plate 20 is fixedly connected to one side of the processing box 1. The lowest point of the lower pressure plate 20 is flush with the bottom of the grinding belt 6. By setting the lower pressure plate 20, when the grinding balls are conveyed by the conveyor belt 9, they are guided by the lower pressure plate 20 which is inclined to the lower right and conveyed to the bottom of the grinding belt 6 to prevent the material from jamming.

[0030] The separation mechanism includes a separation box 3 located on one side of the processing box 1. A filter plate 11 is rotatably connected to the bottom of the separation box 3. A drive structure for driving the filter plate 11 to vibrate is provided on the top of the separation box 3. The filter plate 11 is driven to vibrate by the drive structure. When the grinding balls are transported through the filter plate 11 in the separation box 3, the rapid vibration will filter the grinding debris from the filter plate 11 for cleaning.

[0031] The driving mechanism includes a take-up reel 13 that is driven to rotate on the separation box 3 by a motor. A pull rope 14 is connected to the surface of the take-up reel 13. One end of the pull rope 14 passes through and extends into the inner cavity of the separation box 3. The bottom end of the pull rope 14 is fixedly connected to the top of the filter plate 11. The take-up reel 13 is driven to rotate back and forth by the motor, which causes the pull rope 14 to tighten and loosen, causing the filter plate 11 to shake back and forth. The motor is a stepper motor, which can drive the filter plate 11 to shake continuously for separation.

[0032] The bottom of the separation box 3 is fixed with a blower head 12 with the air outlet facing the bottom of the filter plate 11. The blower head 12 is connected to an external fan. The inner cavity of the separation box 3 above the filter plate 11 is fixedly connected with a baffle plate 15. A guide slope 16 is opened on the left side of the baffle plate 15, and a slag collection tank 17 is opened on the right side of the baffle plate 15. When in use, the airflow blown out by the blower head 12 blows off the iron filings adhering to the surface of the grinding ball, preventing them from adhering to the surface of the grinding ball. At this time, the lighter iron filings are blown up by the airflow blown out by the blower head 12 and blown to the top of the baffle plate 15. After being guided by the guide slope 16, they are collected in the slag collection tank 17 under the blowing of the airflow. The heavier iron filings are filtered out from the mesh in the filter plate 11 and separated.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
