Description

Technical Field

[0001] This utility model relates to the field of weighing support technology, and in particular to a high-precision quantitative packaging machine for kernels. Background Technology

[0002] The high-precision seed and kernel quantitative packaging machine is a device specifically designed for packaging seed and kernel materials. It helps enterprises improve production efficiency, ensure product quality, reduce costs, and meet the market demand for high-precision packaging products.

[0003] In the existing technology, high-precision kernel quantitative packaging machines cannot accurately control the weight of each bag of kernels, resulting in large differences in weight between bags. When the kernel packaging weight is inaccurate, manual secondary weighing and replenishment are required, which increases labor costs and labor intensity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing high-precision seed kernel quantitative packaging machines, which cannot accurately control the weight of each bag of seeds, resulting in significant weight differences between bags. Therefore, this invention proposes a high-precision seed kernel quantitative packaging machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision kernel quantitative packaging machine, comprising a frame, a lifting assembly, a feeding pipe, and a metering device. A weighing device is provided on one side of the frame. The weighing device includes four fixed rods, one end of which is fixedly connected to the frame. A base plate is fixedly connected to one end of each of the four fixed rods. Four dampers are fixedly connected to the top of the base plate. A top plate is fixedly connected to the output end of each of the four dampers. A shock-absorbing spring is fitted onto the arc surface of each damper. The two ends of each of the four shock-absorbing springs are fixedly connected to the top plate and the base plate, respectively. Three high-precision pressure sensors are fixedly connected to the top of the top plate. A weighing platform is fixedly connected to one end of each of the three high-precision pressure sensors.

[0006] The effect achieved by the above components is that the force on the weighing platform is transmitted to the high-precision pressure sensor, and then transmitted through the top plate, so that the damper and shock-absorbing spring are in a compressed state.

[0007] Preferably, a U-shaped support plate is fixedly connected to the top of the base plate.

[0008] The effect achieved by the above components is that the U-shaped support plate is fixed on the base plate.

[0009] Preferably, a pressure pad, which is made of rubber, is fixedly connected to one side of the U-shaped support plate.

[0010] The effect achieved by the above components is that the pressure pad is fixed on the U-shaped support plate.

[0011] Preferably, two limiting plates are fixedly connected to the top of the base plate.

[0012] The effect achieved by the above components is to fix the limiting plate to the base plate.

[0013] Preferably, the limiting plate is slidably connected to a guide frame, and the side of the two guide frames that are close to each other is fixedly connected to the weighing platform.

[0014] The effect achieved by the above components is that the movement of the weighing platform causes the guide frame to slide on the limit plate, thus preventing the weighing platform from shifting its position during movement.

[0015] Preferably, one end of each of the two limiting plates is provided with a cleaning device, the cleaning device comprising two L-shaped plates, one end of each L-shaped plate being fixedly connected to the limiting plate, and one end of each L-shaped plate being fixedly connected to an electric guide rail.

[0016] The above components achieve the following effect: the electric guide rail is fixed on the L-shaped plate, and the L-shaped plate is fixed on the limiting plate.

[0017] Preferably, the electric guide rail is externally slidably connected to a guide block.

[0018] The effect achieved by the above components is to enable the electric guide rail to start and drive the guide block to slide for position adjustment.

[0019] Preferably, a connecting plate is fixedly connected to one side of the guide block, and a horizontal plate is fixedly connected to one side of the two connecting plates.

[0020] The effect achieved by the above components is that the movement of the guide block drives the adjustment of the position of the connecting plate, so that the horizontal plate moves synchronously.

[0021] Preferably, a cleaning scraper is fixedly connected to one side of the horizontal plate.

[0022] The effect achieved by the above components is to fix the cleaning scraper on the horizontal plate.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a weighing device is used to monitor the weight of the falling kernels in real time when quantitative packaging is required. A high-precision pressure sensor accurately weighs the kernels, and when the weight reaches the preset target value, the feeding pipe is closed. This weighing device solves the problem that traditional high-precision kernel quantitative packaging machines cannot accurately control the weight of each bag of kernels, resulting in large weight differences between bags. When the kernel packaging weight is inaccurate, manual re-weighing and refilling are required, increasing labor costs and labor intensity.

[0025] In this invention, when it is necessary to clean the debris on the surface of the weighing platform, the electric guide rail is activated to drive the guide block to slide, causing the connecting plate to move the horizontal plate. The cleaning scraper then scrapes away the debris from the surface of the weighing platform. This cleaning device solves the problem that traditional high-precision kernel quantitative packaging machines are not convenient for automatically cleaning the surface of the weighing platform. During weighing, debris can change the force on the platform, causing changes in the pressure on the high-precision pressure sensor and resulting in deviations in the measurement results.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a high-precision quantitative packaging machine for kernels, including a frame 1, a lifting assembly 4, a feeding pipe 5 and a metering device 6. A weighing device 2 is provided on one side of the frame 1, and a cleaning device 3 is provided at one end of the two limit plates 211.

[0032] The specific setup and function of the weighing device 2 and the cleaning device 3 will be explained in detail below.

[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the weighing device 2 includes four fixed rods 201. One end of each fixed rod 201 is fixedly connected to the frame 1. A base plate 202 is fixedly connected to one end of each fixed rod 201. Four dampers 203 are fixedly connected to the top of the base plate 202. A top plate 205 is fixedly connected to the output end of each damper 203. A shock-absorbing spring 204 is fitted onto the arc surface of each damper 203. Both ends of the four shock-absorbing springs 204 are fixedly connected to the top plate 205 and the base plate 202, respectively. Three high-precision pressure sensors 206 are fixedly connected to the top of the top plate 205. One end of each high-precision pressure sensor 206 is fixedly connected to the weighing platform 207. This achieves the effect of transmitting force from the weighing platform 207 to the high-precision pressure sensors 206, and then through the top plate 205, thus compressing the dampers 203 and the shock-absorbing springs 204. A U-shaped support plate 208 is fixedly connected to the top of the base plate 202. The U-shaped support plate 208 is fixed to the base plate 202. A pressure pad 209, made of rubber, is fixedly connected to one side of the U-shaped support plate 208. The pressure pad 209 is fixedly attached to the U-shaped support plate 208. Two limiting plates 211 are fixedly connected to the top of the base plate 202. The limiting plates 211 are fixedly attached to the base plate 202. Guide frames 210 are slidably connected to the outside of the limiting plates 211, and the sides of the two guide frames 210 that are close to each other are fixedly connected to the weighing platform 207. This ensures that the movement of the weighing platform 207 causes the guide frames 210 to slide on the limiting plates 211, preventing the weighing platform 207 from shifting position during movement.

[0034] Reference Figure 4 As shown in this embodiment: the cleaning device 3 includes two L-shaped plates 31. One end of the L-shaped plate 31 is fixedly connected to the limiting plate 211, and an electric guide rail 32 is fixedly connected to one end of the L-shaped plate 31. This achieves the effect of the electric guide rail 32 being fixed on the L-shaped plate 31, and the L-shaped plate 31 being fixed on the limiting plate 211. A guide block 33 is slidably connected to the outside of the electric guide rail 32. This achieves the effect of the electric guide rail 32 driving the guide block 33 to slide and adjust its position. A connecting plate 34 is fixedly connected to one side of the guide block 33, and a horizontal plate 35 is fixedly connected to one side of the two connecting plates 34. This achieves the effect of the guide block 33 moving to drive the connecting plate 34 to adjust its position, so that the horizontal plate 35 moves synchronously. A cleaning scraper 36 is fixedly connected to one side of the horizontal plate 35. This achieves the effect of the cleaning scraper 36 being fixed to the horizontal plate 35.

[0035] Working Principle: When quantitative packaging of kernels is required, the operator first hangs the packaging bag on the lifting assembly 4 via the weighing device 2. Through precise adjustment, the inlet of the packaging bag is seamlessly connected to the discharge pipe 5. Once ready, the discharge pipe 5 is activated, and the kernels begin to fall at a uniform speed. During this process, the metering device 6 integrated at the discharge port of the discharge pipe 5 monitors the weight of the falling kernels in real time and records the data synchronously. Simultaneously, as the kernels are continuously filled, the weight of the packaging bag placed on the weighing platform 207 continuously increases. The resulting gravity is transmitted through the weighing platform 207 to the high-precision pressure sensor 206. The high-precision pressure sensor 206 converts the mechanical signal into accurate weight data. To ensure that the weighing data is not disturbed by external vibrations, the top plate 205, when bearing the weight, transmits the force to the vibration isolation system composed of the damper 203 and the shock-absorbing spring 204. However, the weighing platform 207 needs optimization. The connection structure between the damper 203, the shock-absorbing spring 204, and the high-precision pressure sensor 206 ensures a clear and stable force transmission path. Through the dual effects of elastic buffering and damping energy dissipation, environmental vibrations are effectively filtered, ensuring weighing accuracy. When the data monitored by the meter 6 and the high-precision pressure sensor 206 show that the weight of the kernels in the packaging bag reaches the preset target value, the two immediately trigger a control command, driving the closing device of the feeding pipe 5 to quickly and accurately cut off the kernel flow, achieving millisecond-level response to terminate the feeding. Finally, the entire process of high-precision quantitative packaging is automated. Through the weighing device 2, the problem of traditional high-precision kernel quantitative packaging machines being unable to accurately control the weight of each bag of kernels, resulting in large weight differences between bags, and requiring manual re-weighing and replenishment when the kernel packaging weight is inaccurate, increases labor costs and labor intensity.

[0036] When cleaning the surface of the weighing platform 207 needs to be cleaned using the cleaning device 3, the operator first starts the electric guide rail 32. The electric guide rail 32 drives the guide block 33 mounted on it to slide. The movement of the guide block 33 causes the connecting plate 34 to move synchronously, which in turn causes the horizontal plate 35 connected to it to move. Finally, it drives the cleaning scraper 36 installed on the horizontal plate 35 to scrape away the debris on the surface of the weighing platform 207, completing the cleaning work. The cleaning device 3 solves the problem that traditional high-precision kernel quantitative packaging machines are not convenient for automatically cleaning the surface of the weighing platform 207. During weighing, debris will change the force on the platform, causing the pressure on the high-precision pressure sensor 206 to change, resulting in deviations in the measurement results.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
