Description

Technical Field

[0002] The metering mechanism is the core of quantitative packaging, and accuracy, stability, and feeding speed are the standards for evaluating quantitative packaging machinery. Existing metering mechanisms use load cells that can meet the accuracy and stability requirements of production; however, their dispensing mechanisms mostly rely on cylinders to open or close the feeding gate. This makes it difficult to control the feeding speed for different materials (good or poor flowability) and different target quantities (such as 5kg, 10kg, 25kg, etc.). As the feeding speed increases, accuracy and stability inevitably decrease, making it impossible to achieve all three simultaneously. In actual production, high-precision metering devices are widely used, and feeding speed becomes the main factor limiting production efficiency. Summary of the Invention

[0028] Example 1

[0029] like Figure 1 , 2 As shown in Figure 3, this embodiment provides a high-speed metering device for multi-stage batching, including a batching mechanism 1, a metering mechanism 2, and a frame 3. The batching mechanism 1 and the metering mechanism 2 are disposed in the frame 3, with the batching mechanism 1 located above the metering mechanism 2.

[0030] The batching mechanism 1 includes an installation frame 11, a batching bin 12, and a first power mechanism 13. The installation frame 11 is fixedly mounted on the frame 3. The batching bin 12 is located in the installation frame 11. The first power mechanism 13 is located outside the installation frame 11. The first power mechanism 13 is connected to the batching bin 12 and drives the batching bin 12 to open and close.

[0031] The principle of this utility model is that the batching mechanism 1 adopts a three-stage batching method when batching. That is, the batching process is divided into three stages: front, middle and back. Different batching amounts are adopted according to the flowability of the material and the target amount. The opening of the batching bin 12 is precisely controlled by the first power mechanism 13 to achieve precise control of the batching amount, thereby satisfying the combination of batching speed and accuracy.

[0032] like Figure 2 , 4 As shown in Figure 5, further, the batching bin 12 includes a feed cylinder 121 and a bin door 122. The feed cylinder 121 is disposed in the mounting frame 11. The bin door 122 includes an inner bin door and an outer bin door. The inner bin door and the outer bin door are disposed opposite each other at the lower part of the feed cylinder 121 and close the bottom of the feed cylinder 121. The first power mechanism 13 includes a drive motor 131, a transmission rod 132, an inner bin door swing arm 133, and an outer bin door swing arm 134. The drive motor 131 is disposed on the mounting frame 11. The transmission rod 132 is disposed on the output end of the drive motor 131. The inner bin door swing arm 133 and the outer bin door swing arm 134 are movably disposed on the transmission rod 132. The inner bin door and the inner bin door swing arm 133 are movably connected, and the outer bin door and the outer bin door swing arm 134 are movably connected.

[0033] like Figure 4 , 6As shown, the middle part of the transmission rod 132 is connected to the output end of the drive motor 131, and the inner door swing arm 133 and the outer door swing arm 134 are respectively connected to the two ends of the transmission rod 132.

[0034] Furthermore, both the inner and outer compartment doors include a compartment door plate and a connecting arm. The connecting arm is connected to the side of the feed cylinder 121 by a pin, with the pin located in the middle of the connecting arm. The compartment door plate is located at the bottom of the connecting arm. The inner compartment door swing arm 133 is connected to the upper end of the connecting arm of the inner compartment door, and the outer compartment door swing arm 134 is connected to the upper end of the connecting arm of the outer compartment door. When the inner compartment door swing arm 133 and the outer compartment door swing arm 134 move, they drive the inner and outer compartment doors to move relative to each other.

[0035] like Figure 2 , 5 As shown, the mounting frame 11 further includes an outer housing 111, a guide pipe 112, and a mounting plate 113. The outer housing 111 is mounted on the frame 3 and is used to mount the material hopper 12, which is located inside the outer housing 111. The guide pipe 112 is located at the top of the outer housing 111, and its top is connected to the material hopper. The bottom of the guide pipe 112 is located inside the material hopper 12. The mounting plate 113 is mounted on the outer housing 111 and is used to mount the first power mechanism 13 and the limit position sensor 4. The first power mechanism 13 is mounted on the mounting plate 113.

[0036] like Figure 2 , 5 As shown, the guide pipe 112 further includes an upper guide pipe and a lower guide pipe. The lower guide pipe is located at the top of the outer casing 111, and the bottom of the lower guide pipe extends into the feed cylinder 121. The upper guide pipe is fixedly connected above the lower guide pipe and is connected to the material hopper. The material in the material hopper is guided to the feed cylinder 121 through the upper and lower guide pipes.

[0037] The batching mechanism 1 performs the batching process as follows: When the bin door 122 is closed, the material flows directly from the material bin to the batching bin 12. When the bin door 122 is open, the drive motor 131 moves counterclockwise, which drives the inner bin door swing arm 133 and the outer bin door swing arm 134 to move synchronously through the transmission rod 132, so that the inner bin door and the outer bin door move inward synchronously to close the lower outlet of the feed cylinder 121. After that, the material flows directly from the material bin to the batching bin 12.

[0038] Different batching amounts are used based on the flowability and target quantity of the material. Flowability is related to particle shape; long particles have poor flowability, while round particles have better flowability. The target quantity is divided into different batching weights such as 5kg, 10kg, and 25kg. The specific batching method is as follows:

[0039] When the material is a round shape with good flowability and the target quantity is small, the advance amount for the first-stage batching is set relatively large. The drive motor 131 is controlled to move clockwise, which drives the inner door swing arm 133 and the outer door swing arm 134 to move synchronously through the transmission rod 132, opening the inner and outer doors to the set position to perform the first-stage batching of the metering mechanism 2. Then, when the sensor assembly 21 detects that the batching has reached the set advance amount, the drive motor 131 is controlled to move counterclockwise, closing the inner and outer doors to the set position again to perform the second-stage batching. The advance amount for the second-stage batching is also set relatively large based on the remaining weight of the first-stage batching. After completing the second-stage batching using the same process, the drive motor 131 is controlled to move counterclockwise again, closing the inner and outer doors to the set position again to perform the third-stage batching. When the set target quantity is reached, the drive motor 131 is controlled to move counterclockwise again to completely close the inner and outer doors, completing the three-stage batching. The one-time batching process is divided into three stages, and different batching amounts are set for the three stages according to the flowability of the materials and the target amount, so as to achieve fast and accurate batching. The precise, fast and flexible control of the drive motor 131 is used to achieve precise control of the batching amount.

[0040] When the material is a round shape with good flowability and the target quantity is large, the three-stage batching method is as follows: the lead time of the first-stage batching is set relatively small, the lead time of the second-stage batching is also set relatively small in the remaining weight of the first-stage batching, and finally the target quantity is completed by the third-stage batching.

[0041] When the material is long and has poor flowability and the target quantity is small, the three-stage batching method is as follows: the lead time of the first stage batching is set to be large, the lead time of the second stage batching is also set to be large based on the remaining weight of the first stage batching, and finally the third stage batching completes the target quantity.

[0042] When the material is long and has poor flowability and the target quantity is large, the three-stage batching method is as follows: the lead time of the first-stage batching is set relatively large, the lead time of the second-stage batching is also set relatively large based on the remaining weight of the first-stage batching, and finally the target quantity is achieved by the third-stage batching.

[0043] like Figure 4 , 5 As shown in Figure 6, the metering mechanism 2 further includes a sensor assembly 21, a metering cylinder assembly 22, and a second power mechanism 23. The sensor assembly 21 is arranged in a group on the frame 3. The sensor assembly 21 is used to install the metering cylinder assembly 22 and perform real-time metering. The sensor 211 detects the material flowing into the metering cylinder 221 in real time and controls the drive motor 131 to adjust the opening. The metering cylinder assembly 22 is connected to the sensor assembly 21 and is located below the batching bin 12. The second power mechanism 23 is arranged on the metering cylinder assembly 22 and drives the metering cylinder assembly 22 to open and close.

[0044] like Figure 4 , 5 As shown in Figure 6, the sensor assembly 21 further includes a sensor 211, a mounting base 212, and a lifting rod 213.

[0045] like Figure 4 , 5 As shown in Figure 6, the metering cylinder assembly 22 further includes a metering cylinder 221 and a discharge gate 222. The bottom end of the lifting rod 213 is connected to the metering cylinder 221. The discharge gate 222 is movably disposed on the metering cylinder 221. The discharge gate 222 includes a front discharge gate and a rear discharge gate. The front discharge gate and the rear discharge gate are disposed opposite to each other at the lower part of the metering cylinder 221 and close the bottom end of the metering cylinder 221.

[0046] Furthermore, both the front and rear discharge gates are connected to the metering cylinder 221 via pins.

[0047] Furthermore, the measuring cylinder 221 is provided with an inspection door on its side.

[0048] like Figure 4 , 6 As shown, the second power mechanism 23 further includes a drive cylinder 231 and a push rod 232.
