Description

Technical Field

[0001] This invention relates to the field of feeding machine technology, and in particular to a feeding machine with an automatic feeding and metering mechanism. Background Technology

[0002] A feeder is a widely used piece of machinery across various industries, primarily used to uniformly and continuously supply materials, ensuring a smooth and efficient production process. It automatically proportions and conveys various raw materials according to set ratios or weights, making it an indispensable tool in modern industrial production.

[0003] Chinese patent CN114275556B discloses a feeder with feeding and metering functions, including a mounting frame, a discharge component fixedly connected to one end of a T-shaped pipe, and a feeding component fixedly connected to the other end of the T-shaped pipe. A transport component is equipped with a carrying tray for discharging material. The discharge component and the feeding component are staggered, and the feeding component can replenish the carrying tray after the discharge component completes the initial discharging operation. A weighing component, including a force gauge and a suction cup, is also installed on the mounting frame. After the initial discharging operation is completed by the discharge box, the carrying tray is transported by the conveyor belt. The cylinder moves directly below the weighing cylinder and operates, using a suction cup to pick up the supporting tray below. The tension gauge at the bottom of the cylinder's telescopic rod converts the overall weight of the supporting tray into tension information, thereby directly obtaining the overall weight change of the supporting tray. This allows for adjustment of the feeding rate at the bottom of the elastic sleeve, achieving precise control of the material weight on the supporting tray. However, after the initial discharge from the discharge box, the material scatters onto the supporting tray. When the suction cup is used to pick up the supporting tray, it is very easy for material to adhere to the suction cup. The feeding component replenishes the material. When the supporting tray is placed on the conveyor belt, the material on the suction cup is very easy to fall off, thus reducing the discharge accuracy.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop a feeder with an automatic feeding and metering mechanism. During the feeding process, there is no need for a suction cup to adhere to the carrying tray for weighing and metering, which reduces the occurrence of material spilling onto the carrying tray that has already been weighed and improves feeding accuracy. Summary of the Invention

[0005] To improve feeding accuracy, this application provides a feeder with an automatic feeding and metering mechanism.

[0006] The feeder with automatic feeding and metering mechanism provided in this application adopts the following technical solution:

[0007] A feeder with an automatic feeding and metering mechanism includes a material tray for holding material and a conveyor belt for conveying the material tray. The conveyor belt is rotatably mounted on a machine base. A feeding and metering mechanism is mounted on the machine base. The feeding and metering mechanism includes a first weighing platform for weighing the material tray, a transfer bin mounted above the first weighing platform, a rotating plate hinged to the transfer bin, a feeding bin for replenishing material, a second weighing platform for weighing and replenishing material, and a hopper mounted on the second weighing platform. The first weighing platform is located beside the conveyor belt, and the second weighing platform is located on the transfer bin. On the plate, the feeding bin is located next to the transfer bin, and an elastic material transfer pipe is provided at the outlet of the feeding bin. The outlet of the elastic material transfer pipe is located inside the hopper. The feeding bin is provided with a control mechanism for controlling the discharge. A first drive mechanism for driving the rotating plate is provided next to the transfer bin. A feed inlet is opened on the side of the transfer bin, and the hopper outlet is close to the feed inlet. A turning mechanism for turning the holding tray is provided on the machine base. The first weighing platform and the second weighing platform are electrically connected. The first weighing platform and the second weighing platform are connected to an external control terminal.

[0008] By adopting the above technical solution, a conveyor belt is rotated and mounted on the machine platform. A first weighing platform is located beside the conveyor belt. A transfer bin is located above the first weighing platform, and a rotating plate is hinged to the transfer bin. A second weighing platform is mounted on the rotating plate, and a hopper is located on the second weighing platform. A feed inlet is opened on the side of the transfer bin, and the hopper outlet is close to the feed inlet. A replenishment bin is located beside the transfer bin, and an elastic conveying pipe is installed at the outlet of the replenishment bin. The outlet of the elastic conveying pipe is located inside the hopper. The first and second weighing platforms are electrically connected, and the first and second weighing platforms are connected to an external control system. The two ends are connected. During the process of conveying the material tray by the conveyor belt, the tossing mechanism moves the material tray to the first weighing platform for weighing. The difference between the current material tray measurement and the standard measurement is obtained through the external control terminal. The feeding bin is replenished by the control mechanism. The material falls onto the hopper. The second weighing platform weighs the hopper. When the material in the hopper meets the difference requirement, the control mechanism is closed. The rotating plate is controlled by the first drive mechanism to rotate. The rotating plate drives the hopper to slide the replenished material into the transfer bin. The material then slides into the material tray through the transfer bin, which facilitates accurate feeding.

[0009] Preferably, the machine base is provided with a first storage platform, the replenishment bin is disposed on the first storage platform, and the control mechanism includes a first motor disposed on the replenishment bin, a rotating rod fixed on the output shaft of the first motor, a first semicircular plate fixed on the rotating rod, and a second semicircular plate disposed next to the first semicircular plate. The rotating rod is rotatably disposed inside the replenishment bin and is rotatably disposed inside the outlet of the replenishment bin. The first semicircular plate is rotatably disposed inside the outlet of the replenishment bin, and the second semicircular plate is disposed on the rotating rod and is rotatably disposed inside the outlet of the replenishment bin.

[0010] By adopting the above technical solution, the machine base is equipped with a platform, a feeding bin is set on the platform, a motor is set on the feeding bin, a rotating rod is fixed on the output shaft of the motor, the rotating rod is rotatably set inside the feeding bin, and the rotating rod is rotatably set inside the feeding bin's outlet. A semi-circular plate is fixed on the rotating rod, and the semi-circular plate is rotatably set inside the feeding bin's outlet. A second semi-circular plate is set on the rotating rod, and the second semi-circular plate is set beside the first semi-circular plate, and the second semi-circular plate is rotatably set inside the feeding bin's outlet. When it is necessary to adjust the feeding bin for feeding, the drive motor drives the rotating rod to rotate, and the rotating rod drives the first and second semi-circular plates to deflect, so that the first and second semi-circular plates form an angle with the inner wall of the feeding bin's outlet, which facilitates the discharge of materials from the angle, thereby facilitating the control of feeding the feeding bin.

[0011] Preferably, the side of the first semicircular plate can be in contact with the inner wall of the replenishment bin outlet, and the side of the second semicircular plate is away from the inner wall of the replenishment bin. The control mechanism includes an elastic sealing arc plate with one end connected to the second semicircular plate and the other end connected to the inner wall of the replenishment bin outlet. The elastic sealing arc plate seals the gap between the second semicircular plate and the inner wall of the replenishment bin outlet.

[0012] By adopting the above technical solution, the side of the first semicircular plate can fit against the inner wall of the feed hopper outlet, while the side of the second semicircular plate is away from the inner wall of the feed hopper. One end of the elastic sealing arc plate is connected to the second semicircular plate, and the other end of the elastic sealing arc plate is connected to the inner wall of the feed hopper outlet. When the feed hopper is adjusted to feed, the first semicircular plate is obliquely below the second semicircular plate, and the material is discharged from below the first semicircular plate and above the second semicircular plate. When the feed hopper is adjusted to stop feeding, the second semicircular plate gradually flips to a horizontal position, and the material is less likely to slide out. Although the first semicircular plate gradually flips to a horizontal position, it is always above the material, and the material can still easily flow out from the gradually decreasing space below the first semicircular plate, which may reduce the accuracy of feeding. The elastic sealing arc plate seals the gap between the second semicircular plate and the inner wall of the feed hopper outlet, which can avoid the above situation, thereby improving the feeding accuracy and further improving the feeding accuracy.

[0013] Preferably, the first driving mechanism includes a mounting platform disposed on the first placement platform and a cylinder disposed within the mounting platform, and the rotating plate is hinged to the output shaft of the first cylinder.

[0014] By adopting the above technical solution, the mounting platform is set on the first placement platform, the first cylinder is set inside the mounting platform, and the rotating plate is hinged to the output shaft of the first cylinder. When it is necessary to control the hopper to flip, the output end of the first cylinder slides out of the first cylinder, and the output end of the first cylinder can control the hopper to flip, which makes it easy to adjust the hopper to flip for material replenishment.

[0015] Preferably, the machine platform is provided with a second conveyor belt, which is located on the side of the first weighing platform away from the first conveyor belt. The actuating mechanism includes a mounting strip on the machine platform, a second motor on the mounting strip, a first screw fixed to the output shaft of the second motor, a slide block threaded onto the first screw, and a lever for actuating the material tray. A sliding groove is provided on the top surface of the mounting strip. The first screw rotates and is disposed in the sliding groove. The slide block is slidably disposed in the sliding groove. The lever rotates and is disposed on the slide block.

[0016] By adopting the above technical solution, a second conveyor belt is set on the machine base, located on the side of the first weighing platform away from the first conveyor belt. An installation strip is set on the machine base, and a sliding groove is opened on the top surface of the installation strip. A second motor is set on the installation strip, and a first screw is fixed on the output shaft of the second motor. The first screw rotates and is set in the sliding groove. A slide block is threaded onto the first screw and slides in the sliding groove. A lever is rotated and set on the slide block. When it is necessary to move the material tray, the drive motor drives the first screw to rotate, causing the slide block and lever to slide closer to the side of the material tray away from the replenishment bin. The drive motor drives the first screw to rotate in the opposite direction, so that the slide block drives the lever to push the material tray onto the first weighing platform for weighing. After the material tray is replenished, the drive lever moves the material tray onto the second conveyor belt for continued conveying of the material tray.

[0017] Preferably, a rotating hole is provided on the side of the slide, and the rotating hole is connected to the top surface of the slide. The actuating mechanism includes a motor three mounted on the slide and a rotating shaft fixed on the output shaft of the motor three.

[0018] By adopting the above technical solution, a rotating hole is opened on the side of the slide, which is connected to the top surface of the slide. The motor is mounted on the slide, and the rotating shaft is fixed on the output shaft of the motor. The rotating shaft is rotatably mounted inside the slide and inside the rotating hole. The lever is mounted on the rotating shaft and inside the rotating hole. When it is necessary to drive the lever to rotate, the motor drives the rotating shaft to rotate, and the rotating shaft drives the lever to rotate, which makes it easy to adjust the lever to move closer to or away from the material tray.

[0019] Preferably, a mounting groove is provided on the top surface of the machine tool, and a second cylinder is provided in the mounting groove. The first weighing platform is fixed on the output shaft of the second cylinder and is vertically slidably disposed in the mounting groove.

[0020] By adopting the above technical solution, an installation groove is opened on the top surface of the machine tool, and a second cylinder is installed in the installation groove. The first weighing platform is fixed on the output shaft of the second cylinder and is vertically slidably installed in the installation groove. When material needs to be replenished, the second cylinder drives the material tray on the first weighing platform to move upward, so that the material tray to be replenished is close to the transfer bin, avoiding the possibility of material spilling out of the material tray during the replenishment process and improving the stability of the replenishment process.

[0021] Preferably, the machine base is provided with a feeding mechanism, which includes a second platform on the machine base, a feeding bin on the second platform, a transfer box below the feeding bin, a fourth motor on the transfer box, a conical screw fixed to the output shaft of the fourth motor, and a transfer bin above the first conveyor belt.

The conical screw is rotatably disposed in the material transfer groove. The transfer box is connected to the transfer bin, and the material transfer groove is connected to the transfer bin.

The transfer box is connected to the transfer bin, and the material transfer groove is connected to the transfer bin. The fourth motor is set on the transfer box, and the conical screw is fixed on the output shaft of the fourth motor. The conical screw is rotatably set in the material transfer groove. During the process of the feeding bin feeding the material tray, the fourth motor drives the conical screw to rotate so as to transfer the material to the transfer bin for easy feeding.

[0023] Preferably, the control component includes a discharge pipe disposed on the transfer chamber, a motor five disposed on the discharge pipe, a rotating column fixed on the output shaft of the motor five, and a lever disposed on the rotating column. The discharge pipe is connected to the outlet of the transfer chamber.

The side of the deflector can fit against the inner wall of the discharge pipe. During the discharge process, the drive motor 5 drives the rotating column to rotate, and the rotating column drives the deflector to push the material at a uniform speed, so that the material is evenly sprinkled on the receiving plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A conveyor belt is mounted on the machine platform. A first weighing platform is located beside the conveyor belt. A transfer hopper is located above the first weighing platform, and a rotating plate is hinged to the transfer hopper. A second weighing platform is located on the rotating plate, and a hopper is located on the second weighing platform. A feed inlet is located on the side of the transfer hopper, and the hopper outlet is close to the feed inlet. A replenishment hopper is located beside the transfer hopper, and a flexible conveying pipe is installed at the outlet of the replenishment hopper. The outlet of the flexible conveying pipe is located inside the hopper. The first and second weighing platforms are electrically connected and connected to an external control terminal. During the process of conveying the material tray using the conveyor belt, the material tray is moved to the first weighing platform by the tossing mechanism for weighing. The difference between the current material tray measurement and the standard measurement is obtained through the external control terminal. The material is replenished by the replenishment bin through the control mechanism. The material falls onto the hopper, and the second weighing platform weighs the hopper. When the material in the hopper meets the difference requirement, the control mechanism is closed. The rotating plate is controlled by the first drive mechanism to rotate. The rotating plate drives the hopper to slide the replenished material into the transfer bin, and then into the material tray, which facilitates precise feeding.

[0027] 2. The side of the first semicircular plate can fit against the inner wall of the feed hopper outlet, while the side of the second semicircular plate is away from the inner wall of the feed hopper. One end of the elastic sealing arc plate is connected to the second semicircular plate, and the other end of the elastic sealing arc plate is connected to the inner wall of the feed hopper outlet. When the feed hopper is adjusted to feed, the first semicircular plate is obliquely below the second semicircular plate, and the material is discharged from below the first semicircular plate and above the second semicircular plate. When the feed hopper is adjusted to stop feeding, the second semicircular plate gradually flips to a horizontal position, and the material is less likely to slide out. Although the first semicircular plate gradually flips to a horizontal position, it is always above the material, and the material can still easily flow out from the gradually decreasing space below the first semicircular plate, which may reduce the accuracy of feeding. The elastic sealing arc plate seals the gap between the second semicircular plate and the inner wall of the feed hopper outlet, which can avoid the above situation, thereby improving the feeding accuracy and further improving the feeding accuracy.

Motor 5 is installed on the discharge pipe, and the rotating column is fixed on the output shaft of motor 5. The rotating column is rotatably installed inside the discharge pipe. The baffle plate is installed on the rotating column and is rotatably installed inside the discharge pipe. The side of the baffle plate can fit against the inner wall of the discharge pipe. During the discharge process, motor 5 drives the rotating column to rotate, and the rotating column drives the baffle plate to move the material at a uniform speed, so that the material is evenly sprinkled on the receiving plate, improving the uniformity of discharge.

The transfer bin 42 is installed on the first placement platform 11. The discharge port of the transfer bin 42 extends into the first placement platform 11. The transfer bin 42 is located above the first weighing platform 41.

[0043] Reference Figure 1 and Figure 3 As shown, the rotating plate 43 is hinged to the rotating hopper 42, the second weighing platform 45 is set on the rotating plate 43, the hopper 46 is set on the second weighing platform 45, the rotating hopper 42 has a feed inlet on its side, the outlet of the hopper 46 is close to the feed inlet, the replenishing hopper 44 is set next to the rotating hopper 42 and is set on the platform 11, the outlet of the replenishing hopper 44 is provided with an elastic conveying pipe, the outlet of the elastic conveying pipe is set inside the hopper 46, the first weighing platform 41 and the second weighing platform 45 are electrically connected, and the first weighing platform 41 and the second weighing platform 45 are connected to an external control terminal.

[0044] Reference Figure 1 , Figure 3 and Figure 4 As shown, when replenishment is needed, the second drive cylinder 13 drives the material tray 3 on the first weighing platform 41 to move upward, so that the material tray 3 that needs to be replenished is close to the transfer bin 42, avoiding the possibility of material spilling out of the material tray 3 during the replenishment process and improving the stability of the replenishment process.

[0046] Reference Figure 2 As shown, the second semicircular plate 54 is mounted on the rotating rod 52 and is positioned next to the first semicircular plate 53. The second semicircular plate 54 is rotatably mounted inside the outlet of the feeding bin 44. When the feeding bin 44 needs to be adjusted for feeding, the drive motor 51 drives the rotating rod 52 to rotate. The rotating rod 52 drives the first semicircular plate 53 and the second semicircular plate 54 to deflect, so that the first semicircular plate 53, the second semicircular plate 54 and the inner wall of the outlet of the feeding bin 44 form an angle, which facilitates the discharge of materials from the angle, thereby facilitating the control of feeding in the feeding bin 44.

[0048] Reference Figure 1 and Figure 2 As shown, when the feeding chamber 44 is being fed, the first semicircular plate 53 is obliquely below the second semicircular plate 54. The material is discharged from below the first semicircular plate 53 and above the second semicircular plate 54.

Although the first semicircular plate 53 gradually flips to a horizontal position, it remains above the material, and the material can still easily flow out from the gradually decreasing space below the first semicircular plate 53, which may reduce the feeding accuracy. The elastic sealing arc plate 55 seals the gap between the second semicircular plate 54 and the inner wall of the outlet of the feeding chamber 44, which can avoid the above situation, thereby improving the feeding accuracy and further improving the feeding accuracy.

When it is necessary to move the material tray 3, the drive motor drives the screw 73 to rotate, causing the slide block 74 and the lever 75 to slide closer to the side of the material tray 3 away from the replenishment bin 44. The drive motor drives the screw 73 to rotate in the opposite direction, causing the slide block 74 to drive the lever 75 to push the material tray 3 onto the first weighing platform 41 for weighing. After the material tray 3 is replenished, the drive lever 75 moves the material tray 3 onto the second conveyor belt 14 for continued conveying of the material tray 3.

The discharge pipe 871 is installed on the transfer chamber 86 and is connected to the outlet of the transfer chamber 86. The motor 872 is installed on the discharge pipe 871. The rotating column 873 is fixed on the output shaft of the motor 872 and is rotatably installed inside the discharge pipe 871.

[0057] Reference Figure 7 As shown, the paddle plate 874 is set on the rotating column 873. There are 6 paddle plates 874, which are evenly distributed at equal distances along the axis of the rotating column 873. The paddle plates 874 are rotatably set inside the discharge pipe 871. The side of the paddle plate 874 can fit against the inner side wall of the discharge pipe 871. During the discharge process, the drive motor 872 drives the rotating column 873 to rotate. The rotating column 873 drives the paddle plate 874 to move the material at a uniform speed, so that the material is evenly sprinkled on the receiving plate.

[0058] The implementation principle of a feeder with an automatic feeding and metering mechanism according to an embodiment of this application is as follows:

[0059] During the process of conveying the material tray 3 using conveyor belt 2, lever 75 is used to move the material tray 3 onto the first weighing platform 41 for weighing. The difference between the current measurement of the material tray 3 and the standard measurement is obtained through an external control terminal. The drive motor 51 drives the rotating rod 52 to rotate, which in turn causes the semicircular plates 53 and 54 to deflect, so that the semicircular plates 53 and 54 form an angle with the inner wall of the outlet of the feeding bin 44. This controls the feeding of material into the feeding bin 44, and the material falls... The material falls onto the hopper 46, and the second weighing platform 45 weighs the hopper 46. When the material in the hopper 46 meets the required difference, the drive motor 51 drives the semi-circular plate 53 to close the outlet of the replenishment bin 44. The output end of the drive cylinder 62 slides out of the cylinder 62. The output end of the cylinder 62 can control the hopper 46 to flip. The rotating plate 43 drives the hopper 46 to slide the replenished material into the transfer bin 42. The material then slides into the receiving tray 3 through the transfer bin 42, which facilitates precise feeding.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
