Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cellulose powder processing technology, specifically relating to a cellulose powder packaging and weighing device based on vibration function. Background Technology
[0002] In the packaging process of cellulose powder products, due to the low bulk density of the powder, traditional packaging methods typically require weighing first, followed by transferring the packaging bags to a separate compaction table for compaction. However, this separate operation process has several shortcomings: on the one hand, the powder is prone to loose accumulation in the packaging bags, leading to inaccurate actual weight, often requiring manual or repeated weighing, increasing labor intensity and operational complexity; on the other hand, the powder is prone to generating dust during transfer and vibration, causing dust pollution in the working environment, affecting production safety and hygiene. Furthermore, multiple transfers and repetitive operations not only reduce overall packaging efficiency but may also lead to unstable weighing accuracy, making it difficult to meet the requirements of automation, continuous operation, and environmental protection in modern production. Utility Model Content
[0003] To address the aforementioned shortcomings of existing technologies, this utility model provides a cellulose powder packaging weighing device based on vibration function, which solves the problem of low packaging efficiency caused by the separation of weighing and vibration compaction processes in existing technologies.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vibration-based cellulose powder packaging weighing device is provided, including a platform scale, which is mounted on a platform scale base. A compaction platform is mounted above the platform scale. The compaction platform is electrically connected to a vibration motor mounted below the compaction platform. The vibration motor and the platform scale are electrically connected to a control system. The top of the compaction platform is connected to the bottom of a conveyor platform. A support is mounted on one side of the conveyor platform, which is mounted above the compaction platform. A feeding device is mounted above the support.
[0005] The beneficial effects of adopting the above technical solution are as follows: The device integrates weighing and vibration compaction functions into one unit, realizing continuous operation of feeding, weighing and compaction at the same workstation. After feeding, it can automatically weigh. If the weight is insufficient, vibration compaction is triggered. After compaction, feeding and weighing are carried out again, and the cycle continues until the packaging requirements are met. This avoids the steps of frequently transferring packaging bags between the weighing table and the vibration compaction table in the traditional process, which significantly improves packaging efficiency, reduces manual intervention, reduces the risk of dust leakage, and ensures the accuracy and consistency of packaging weight. During the feeding stage, the feeding device precisely controls the inflow of cellulose powder, while the support firmly secures the packaging bag, ensuring that the powder falls accurately into the bag without spilling. This reduces errors and dust during the feeding process, providing a stable foundation for subsequent weighing. It also reduces the need for manual bag support, improving operational safety and automation. During the weighing stage, the platform scale measures weight in real time and converts it into an electrical signal, quickly providing feedback on the actual weight data, ensuring accurate and timely weight detection. During the compaction stage, when the weight is insufficient, the vibration motor starts, driving the compaction table to generate directional vibration, rapidly compacting the powder in the packaging bag and increasing its bulk density. This allows for the addition of more powder, reducing the number of feeding cycles and improving overall packaging efficiency. The control system automatically manages the switching between weighing and vibration modes, intelligently starting and stopping the vibration motor based on weight detection results, achieving fully automated cyclic operation. This reduces manual decision-making and intervention, ensuring process continuity and consistency, improving the reliability and efficiency of the packaging process, and reducing operational complexity.
[0006] Furthermore, the platform scale is equipped with a weighing sensor.
[0007] The beneficial effects of adopting the above technical solution are as follows: the weighing sensor can detect the weight change of the powder in real time and accurately, and feed the data back to the control system. The control system determines whether the current weight is within the preset packaging standard, thereby accurately controlling the subsequent vibration compaction and feeding operations, avoiding repetitive work or insufficient packaging caused by inaccurate weighing, and improving the efficiency and accuracy of the packaging process.
[0008] Furthermore, the weighing sensor is a pressure sensor or a resistance strain gauge sensor.
[0009] Furthermore, the vibration motor is located at the bottom of the compaction table, and a shock-absorbing pad is installed between the compaction table and the platform scale.
[0010] Furthermore, the vibration damping pad is connected to the vibration table and platform scale by bolts.
[0011] The beneficial effects of adopting the above technical solution are as follows: the shock-absorbing pad is set between the platform scale and the vibration compaction platform, and the vibration compaction platform and the platform scale are firmly connected by bolts, which effectively blocks the direct transmission of the excitation force generated by the vibration compaction platform during operation to the platform scale; and during the vibration compaction process, the shock-absorbing pad can absorb and disperse most of the vibration energy, ensuring that the stability and accuracy of the platform scale weighing are not disturbed by vibration, thereby avoiding weighing errors caused by vibration and ensuring the efficient coordination of the weighing and vibration compaction stages in the packaging process.
[0012] In summary, the beneficial effects of the vibration-based cellulose powder packaging and weighing device provided by this utility model are as follows: This device integrates weighing and vibration compaction functions, enabling continuous operation of feeding, weighing, and compaction at the same workstation. At the start of the packaging process, the feeding device initially feeds the powder into the packaging bag, which is securely fixed by a support. The weight of the powder is accurately sensed and weighed by the scale below the compaction table and conveyor platform. If the weight does not meet the standard, without any manual intervention or material transfer, the vibration motor at the bottom of the compaction table starts working under the control of the control system, generating directional vibration. This forces the loose powder particles inside the packaging bag to quickly rearrange and settle, effectively increasing the bulk density of the powder inside the bag without moving the packaging bag, creating space for subsequent replenishment. After the vibration stops, the control system automatically switches back to the weighing mode, and the feeding device accurately replenishes the powder again and immediately performs a second weighing, realizing a cycle of "weighing, judging, compacting, and weighing again." Driven intelligently by the control system, this process can be repeated completely automatically until the weight detected by the scale accurately meets the preset packaging requirements. Throughout the entire process, the packaging bags are securely positioned on the support and conveyor platform, completely avoiding the process interruptions, time delays, manpower consumption, and the most troublesome dust leakage problems caused by the repeated handling between the weighing and vibration tables in traditional methods. Therefore, this device not only greatly improves the efficiency of single-bag packaging and shortens the overall packaging cycle, but also significantly improves the cleanliness and safety of the working environment through its continuous and closed operation mode, while ensuring a high degree of accuracy and consistency in the final package weight.

[0014] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.
[0015] like Figures 1-3 As shown, the cellulose powder packaging weighing device based on vibration function provided by this utility model includes a platform scale 1, which is set on a platform scale base 8. A compaction platform 4 is set above the platform scale 1. The compaction platform 4 is electrically connected to a vibration motor 6 set on the compaction platform 4. The vibration motor 6 and the platform scale 1 are connected to a control system. The vibration motor 6 is set at the bottom of the compaction platform 4. The top of the compaction platform 4 is connected to the bottom of a conveyor platform 3. A support 2 is set on one side of the conveyor platform 3, which is set above the compaction platform 4. A feeding device is set above the support 2. This device integrates weighing and vibration compaction functions into one unit, realizing continuous operation of feeding, weighing and compaction at the same workstation. After feeding, it can automatically weigh. If the weight is insufficient, vibration compaction is triggered. After compaction, feeding and weighing are repeated, and the cycle continues until the packaging requirements are met. This avoids the step of frequently transferring the packaging bag between the weighing platform and the compaction platform 4 in the traditional process, significantly improving packaging efficiency, reducing manual intervention, reducing the risk of dust leakage, and ensuring the accuracy and consistency of the packaged weight. During the feeding stage, the feeding device precisely controls the inflow of cellulose powder, while the support 2 firmly secures the packaging bag, ensuring that the powder falls accurately into the bag without spilling. This reduces errors and dust during the feeding process, providing a stable foundation for subsequent weighing. It also reduces the need for manual bag support, improving operational safety and automation. During the weighing stage, the platform scale 1 measures the weight in real time and converts it into an electrical signal, quickly providing feedback on the actual weight data, ensuring accurate and timely weight detection. During the compaction stage, when the weight is insufficient, the vibration motor 6 starts, driving the compaction table 4 to generate directional vibration, rapidly compacting the powder in the packaging bag and increasing its bulk density. This allows for the addition of more powder, reducing the number of feeding cycles and improving overall packaging efficiency. The control system automatically manages the switching between weighing and vibration modes, intelligently starting and stopping the vibration motor 6 based on the weight detection results, achieving fully automated cyclic operation. This reduces manual decision-making and intervention, ensuring process continuity and consistency, improving the reliability and efficiency of the packaging process, and reducing operational complexity.
[0016] In this invention, a weighing sensor 5 is installed inside the platform scale 1. The weighing sensor 5 is either a pressure sensor or a resistance strain gauge sensor. The weighing sensor 5 can detect the weight change of the powder in real time and accurately, and feed the data back to the control system. The control system then determines whether the current weight is within the preset packaging standard, thereby accurately controlling the subsequent vibration compaction and feeding operations. This avoids repetitive work or insufficient packaging caused by inaccurate weighing, and improves the efficiency and accuracy of the packaging process.
[0017] like Figure 1 As shown, a shock-absorbing pad 7 is installed between the platform scale 1 and the vibrating table 4. The shock-absorbing pad 7 is connected to the vibrating table 4 and the platform scale 1 by bolts. The installation of the shock-absorbing pad 7 between the platform scale 1 and the vibrating table 4, and the secure connection between the vibrating table 4 and the platform scale 1 by bolts, effectively prevents the direct transmission of the excitation force generated by the vibrating table 4 during operation to the platform scale 1. Furthermore, during the vibration compaction process, the shock-absorbing pad 7 can absorb and disperse most of the vibration energy, ensuring that the stability and accuracy of the weighing on the platform scale 1 are not disturbed by vibration, thereby avoiding weighing errors caused by vibration and ensuring the efficient coordination of the weighing and vibration compaction stages in the packaging process.
[0018] In summary, the vibration-based cellulose powder packaging and weighing device provided by this utility model integrates weighing and vibration compaction functions into one workstation, realizing an automated cycle from feeding, weighing to compaction. The packaging bag does not need to be moved throughout the entire process; the system automatically judges the weight and triggers the compaction operation. After compaction, feeding and weighing continue immediately until the target weight is accurately reached. This fundamentally solves the problems of process interruption and material transfer, making the packaging operation continuous, closed, and efficient, significantly increasing the packaging output per unit time, while significantly reducing dust dispersion and weight errors caused by manual handling and operation.
