Description
Technical Field
[0001] This utility model relates to the field of cubic boron nitride processing technology, specifically to an automatic weighing and discharging device for a cubic boron nitride four-column press. Background Technology
[0002] Cubic boron nitride is a superhard material with excellent physicochemical properties and is widely used in machining, aerospace, electronics and other fields. A four-column press is a tool used to prepare cubic boron nitride, and its performance directly affects the quality and yield of the prepared cubic boron nitride.
[0003] In traditional four-column presses, weighing and discharging are usually done manually, which not only increases production costs but also results in low automation and inefficiency, making it difficult to meet the needs of large-scale production. In addition, due to the uncertainty of manual operation, problems such as inaccurate material weighing and unstable production processes may occur, which seriously restricts the preparation quality of cubic boron nitride and affects product quality and production efficiency. Therefore, it is necessary to provide a device that can realize automatic weighing and discharging for cubic boron nitride four-column presses. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic weighing and discharging device for a cubic boron nitride four-column press.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic weighing and discharging device for a cubic boron nitride four-column press includes a device housing, a feed inlet at the top of the device housing, and an openable and closable feed baffle at the feed inlet; and a discharge outlet at the side of the device housing, with an openable and closable discharge baffle at the discharge outlet. The device housing contains a load-bearing balance, which includes a balance telescopic rod and a weight pan and a material pan located at the left and right ends of the balance telescopic rod, respectively. The material pan is located directly below the feed inlet, and the discharge outlet is located in front of the material pan. The load-bearing balance is connected to the feed baffle via a linkage control mechanism. When the material pan is level with the weight pan, the feed baffle is closed; when the weight pan is lower than the material pan, the feed baffle is opened. The device housing is also equipped with a material pushing mechanism. The material discharge baffle opens in conjunction with the material pushing mechanism, and the material pushing mechanism pushes the material on the material tray out of the discharge port.
[0006] Furthermore, the linkage control mechanism includes a wire rope and a fixed pulley group. One end of the wire rope is fixedly connected to the weight pan, and the other end of the wire rope is fixedly connected to the feed baffle through the fixed pulley group. The feed baffle slides left and right at the feed inlet to open and close, and a return spring is connected between the feed baffle and the device housing. When the feed baffle is closed, the return spring is in a stretched state.
[0007] Furthermore, two sets of the fixed pulley block and the wire rope are arranged side by side.
[0008] Furthermore, the fixed pulley assembly includes a bottom fixed pulley and a top fixed pulley.
[0009] Furthermore, the pushing mechanism includes a motor switch installed at the feed inlet. When the feed baffle blocks the feed inlet, the motor switch is triggered. The motor switch is connected to the motor control system, and the motor is connected to the pushing plate through the transmission system, thereby driving the pushing plate to move back and forth. The upper side of the discharge baffle is hinged to the outer shell of the device; the pusher plate is initially located behind the material tray, and the discharge baffle opens as the pusher plate moves forward to push the material.
[0010] Furthermore, the material tray is provided with a sliding groove in the front-to-back direction. When the material tray is level with the weight tray, the slider on the pusher plate corresponds to the sliding groove; the pusher plate moves forward and the slider enters the sliding groove.
[0011] Furthermore, the transmission system includes a rotating shaft disposed outside the device housing and extending in the left-right direction, a second bevel gear mounted on the rotating shaft, a first bevel gear mounted on the output end of the motor, and the first bevel gear and the second bevel gear meshing with each other; a first pulley is also mounted on the rotating shaft. A second pulley is located behind the pusher plate, and a transmission belt is provided between the first pulley and the second pulley. A first connecting rod is fixedly connected to the second pulley. One end of the first connecting rod is rotatably connected to the second connecting rod, and the other end of the second connecting rod is rotatably connected to the pusher plate.
[0012] Furthermore, the feed inlet has a recessed structure, and the feed baffle is located at the bottom of the feed inlet.
[0013] Furthermore, a discharge slope is provided on the outer side of the discharge port, which guides the discharge crusher to the raw material inlet of the cubic boron nitride four-column press.
[0014] The beneficial effects of this utility model are: This invention links the load-bearing balance with the feeding baffle. When the material in the material pan is level with the weights in the weight pan, the feeding baffle can block the feeding port, thereby automatically stopping the feeding. This improves the automation level of weighing, increases the efficiency and accuracy of weighing, and improves product quality.
[0015] This utility model also features an automatic feeding mechanism. When the feeding baffle blocks the feeding port, the motor switch is triggered, and the motor drives the feeding plate to move back and forth through the transmission system to push out the material. The feeding plate can also hold the material tray while pushing the material out. At the same time as the material is pushed out, the feeding baffle remains stationary and still closes the feeding port, thus realizing automated feeding while weighing, saving manpower and improving production efficiency.

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] like Figures 1 to 7 As shown, this embodiment provides an automatic weighing and discharging device for a cubic boron nitride four-column press, including a device housing 1. The top of the device housing 1 is provided with a feed inlet 2, and an openable feed baffle 11 is provided at the feed inlet. In this embodiment, the feed inlet 2 has a recessed structure, the feed baffle 11 is located at the bottom of the feed inlet 2, and the feed baffle 11 slides left and right to open and close at the feed inlet 2.
[0021] The device housing has a discharge port on its side, and an openable discharge baffle 24 is provided at the discharge port. A discharge ramp 3 is also provided outside the discharge port, guiding the discharge crusher to the raw material inlet 4 of the cubic boron nitride four-column press. In this embodiment, the upper side of the discharge baffle 24 is hinged to the device housing, enabling it to swing open and close.
[0022] The device housing contains a balance, which includes a balance telescopic rod 5, and a weight pan 6 and a material pan 7 located at the left and right ends of the balance telescopic rod 5, respectively. The weight pan 6 is hinged to one end of the balance telescopic rod 5 and slidably engaged with the device housing 1; the material pan 7 is hinged to the other end of the balance telescopic rod 5 and slidably connected with the device housing 1.
[0023] The material tray 7 is located directly below the feed inlet 2, and the discharge outlet is located in front of the material tray 7.
[0024] The load-bearing balance is connected to the feed baffle 11 through a linkage control mechanism; when the material pan 7 is level with the weight pan 6, the feed baffle 11 is closed; when the weight pan is lower than the material pan, the feed baffle is opened.
[0025] Specifically, in this embodiment, the linkage control mechanism includes a wire rope 8 and a fixed pulley group, which includes a bottom fixed pulley 9 and a top fixed pulley 10. One end of the wire rope 8 is fixedly connected to the bottom of the weight pan, and the other end of the wire rope 8 is fixedly connected to the feed baffle 11 after passing through the bottom fixed pulley 9 and the top fixed pulley 10.
[0026] Meanwhile, a reset spring 12 is connected between the feed baffle 11 and the device housing 1. When the feed baffle 11 is closed, the reset spring 12 is in a stretched state.
[0027] To ensure stable left and right sliding of the feed baffle 11, two sets of fixed pulley blocks and wire ropes 8 are provided side by side.
[0028] The device housing is also equipped with a material pushing mechanism. The material discharge baffle 24 is opened in conjunction with the material pushing mechanism, and the material pushing mechanism pushes the material on the material tray out of the discharge port.
[0029] In this embodiment, the pushing mechanism includes a motor switch 14 located at the feed inlet. When the feed baffle 11 blocks the feed inlet 2, the motor switch 14 is triggered. The motor switch 14 can be a conventional limit switch or the like. The motor switch 14 is connected to the motor 13, which is connected to the pusher plate 23 via a transmission system, thereby driving the pusher plate 23 to move back and forth. The pusher plate 23 is initially located behind the material tray 7. As the pusher plate 23 moves forward to push the material, the discharge baffle 24 opens along with the material.
[0030] Specifically, the transmission system includes a rotating shaft 17 that is disposed outside the housing of the device and extends in the left-right direction. A second bevel gear 16 is mounted on the rotating shaft 17. A first bevel gear 15 is mounted on the output end of the motor 13. The first bevel gear 15 and the second bevel gear 16 are meshed together. A first pulley 18 is also mounted on the rotating shaft 17.
[0031] A second pulley 19 is provided at the rear of the pusher plate 23. A transmission belt 20 is provided between the first pulley 18 and the second pulley 19. A first connecting rod 21 is fixedly connected to the second pulley 19. One end of the first connecting rod 21 is rotatably connected to the second connecting rod 22, and the other end of the second connecting rod 22 is rotatably connected to the pusher plate 23.
[0032] The material tray 7 is also equipped with a sliding groove in the front-to-back direction. When the material tray 7 is level with the weight tray 6, the slider on the pusher plate 23 corresponds to the sliding groove; the pusher plate 23 moves forward, and the slider enters the sliding groove. This forms a crank-slider mechanism, which realizes the front-to-back movement of the pusher plate 23 through the rotation of the pulley 19.
[0033] The working principle of this utility model is as follows: When no weights are placed in the weight pan 6 and no material is placed in the material pan 7, the material pan 7 is level with the weight pan 6, and the feed baffle 11 is pulled up to completely block the feed inlet 2. The balance telescopic rod 5 is balanced at both ends. When weights are placed in the weight pan 6, the weight pan 6 presses down on the balance telescopic rod 5, causing the material pan 7 to rise. At the same time, the feed baffle 11 opens, exposing the feed inlet 2. Material enters the material pan 7 from the feed inlet 2. The material pan 7 presses down on the balance telescopic rod 5. When the weight of the material pan 7 approaches that of the weight pan 6, the weight pan 6 tilts. Simultaneously, the steel wire rope 8 is pulled, and the steel wire rope 8 pulls the feed baffle 11 through the bottom fixed pulley 9 and the top fixed pulley 10. As the feed baffle 11 moves, the feeding speed decreases, and the weight increase in the material pan 7 decreases. During the pulling of the feed baffle 11, the return spring 12 is stretched, and the elastic force of the return spring 12 continuously increases, causing the balance telescopic rod 5 to rebalance. When the feed baffle 11 completely blocks the feed inlet 2, the feeding in the material pan 7 stops, and the weighing operation is completed. The weight of the material in the material pan 7 is the weight of the weight.
[0034] When the feed baffle 11 completely blocks the feed inlet 2, it triggers the motor switch 14. The motor switch 14 controls the motor 13 to work. The motor 13 drives the first bevel gear 15 to rotate, which in turn drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the rotating shaft 17 to rotate, which in turn drives the first pulley 18 to rotate. The first pulley 18 drives the transmission belt 20, which in turn drives the second pulley 19 to rotate. The rotation of the second pulley 19 causes one end of the first connecting rod 21 to rotate. The first connecting rod 21 pushes the second connecting rod 22, which in turn pushes the pusher plate 23. The pusher plate 23 pushes the material, and the discharge baffle 24 opens as the material moves. At the same time, the pusher plate 23 jams the material tray 7, preventing the material tray 7 from rising. Thus, the feed baffle 11 remains closed. The material passes through the discharge slope 3 and enters the raw material inlet 4 of the cubic boron nitride four-column press, completing the material discharge operation.
[0035] After the material is discharged, the second connecting rod 22 is pushed to the bottom and returns with the rotation of the first connecting rod 21, which drives the pusher plate 23 to return. The discharge baffle 24 automatically falls back. When the pusher plate 23 is separated from the material tray 7, the pusher plate 23 no longer jams the material tray 7. The material tray 7 rises and the weight tray 6 falls. The feed baffle 11 is separated from the motor switch 14 under the action of the reset spring 12. The motor 13 stops working. At the same time, the feed port 2 continues to feed material for the next round of weighing and discharging operation.
[0036] This invention improves the automation level of material weighing, increases the efficiency and accuracy of material weighing, improves product quality, and enables automated material feeding while weighing, saving manpower and improving production efficiency.
