Description

Technical Field

[0001] This utility model relates to the field of bean product packaging technology, specifically a feeding device for bean product packaging. Background Technology

[0002] In automated packaging production lines for legume products (such as soybeans, mung beans, and red beans), the feeding device is a crucial component. Its function is to quantitatively and controllably transport the stored legume products to the downstream weighing station or directly fill them into packaging containers. Current technology often uses a hopper combined with a screw feeder for quantitative feeding. While this method achieves basic quantitative feeding, it has a significant drawback in practical applications.

[0003] After being discharged from the hopper outlet via the screw conveyor, bean products typically experience a certain height difference as they fall into the downstream weighing hopper or packaging container. Under their own gravity, the bean products fall at a high speed, impacting the inner wall of the weighing hopper or packaging container. This continuous, high-speed impact causes several problems: it subjects the structure of the weighing hopper or packaging container to a sustained physical impact, which can easily lead to structural deformation and loosening of connecting parts over time; especially when applied to precision weighing hoppers, this impact force is directly transmitted to the precision load cells below or connected to them, potentially damaging the sensors and severely affecting the stability of the weighing process and the accuracy of the final data, resulting in decreased weighing precision; finally, high-speed collisions between bean products can also cause breakage, affecting product quality.

[0004] Therefore, there is an urgent need for a feeding device that can effectively buffer the impact of falling beans and protect the downstream equipment. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a feeding device for packaging bean products.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A feeding device for packaging bean products includes a fixed frame and a hopper installed at the upper middle part of the fixed frame. A feeding component is provided in the middle of the inner cavity of the hopper. A guide hopper is provided at the bottom middle of the hopper, and a buffer component is provided in the middle of the inner cavity of the guide hopper. The buffer component includes two sets of rollers, which are movably installed on both sides of the inner cavity of the guide hopper. Multiple buffer plates are installed in a circular array on the outer surface of both sets of guide hoppers, and the buffer plates of the two sets of buffer components are staggered. A driving component is provided on the outer wall of the guide hopper, which drives the two sets of rollers to rotate relative to each other.

[0007] Preferably, the feeding assembly includes a rotating shaft with a spiral feeding blade at the bottom. The rotating shaft is movably installed in the middle of the inner side of the hopper and is driven by a feeding motor. The feeding motor is fixedly installed in the middle of the top of the hopper, and a feeding hopper is provided on one side of the top of the hopper.

[0008] Preferably, the drive assembly includes two sets of rotating gears, which are located on the outside of the guide bucket and are respectively installed at the drive shaft ends of the two sets of rollers.

[0009] Preferably, the two sets of rotating gears are respectively connected by a first drive gear and a second drive gear, and the first drive gear and the second drive gear are connected by meshing.

[0010] Preferably, both the first drive gear and the second drive gear are movably mounted on the outer wall of the guide bucket. A first synchronous pulley is provided on the outer side of the second drive gear. The first synchronous pulley is connected to the second synchronous pulley via a synchronous belt drive. The second synchronous pulley is driven by a buffer motor.

[0011] Preferably, a support frame is provided in the middle of the inner side of the fixed frame, the guide bucket is fixedly installed in the middle of the inner side of the support frame, the buffer motor is fixedly installed on the upper surface of the support frame, and the synchronous belt passes through the through hole opened in the inner side of the support frame and is connected to the first synchronous pulley and the second synchronous pulley for transmission.

[0012] Preferably, the discharge pipe at the bottom of the hopper extends into the inner cavity of the guide hopper and is located at the upper middle part of the buffer assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this solution, a buffer assembly consisting of two sets of relatively rotating rollers with staggered buffer plates is installed inside the guide hopper. The falling bean products first impact the rotating buffer plates, and their falling kinetic energy is absorbed and dispersed by the rotational motion of the buffer plates. This greatly reduces the speed and impact force when the bean products finally fall into the downstream weighing hopper or packaging container, thereby effectively reducing the physical impact of the bean products on the downstream weighing hopper, effectively preventing deformation of the weighing hopper structure and loosening of connecting parts, and in particular protecting the precision weighing sensor from impact damage, thus extending the service life of the equipment.

[0016] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 5 As shown, a feeding device for packaging bean products in this embodiment includes a fixed frame 1 and a hopper 2 installed in the middle of the upper end of the fixed frame 1. A feeding assembly is provided in the middle of the inner cavity of the hopper 2. The feeding assembly includes a rotating shaft 3, and a spiral feeding blade 4 is provided at the bottom of the rotating shaft 3. The rotating shaft 3 is movably installed in the middle of the inner side of the hopper 2 and is driven by a feeding motor 5. The feeding motor 5 is fixedly installed in the middle of the top of the hopper 2. A feeding hopper is provided on one side of the top of the hopper 2. The feeding hopper is used to add bean products into the hopper 2. During operation, the feeding motor 5 drives the rotating shaft 3 and the spiral feeding blade 4 to rotate, and pushes the material in the hopper 2 out from the bottom evenly, so as to achieve controllable feeding.

[0017] A guide hopper 7 is located at the bottom center of the hopper 2. A buffer assembly is located in the center of the inner cavity of the guide hopper 7. The discharge pipe at the bottom of the hopper 2 extends into the inner cavity of the guide hopper 7 and is located at the upper center of the buffer assembly, specifically at the upper center of the area formed by the two sets of rollers 8 and their buffer plates 9. This ensures that the material discharged from the hopper 2 can fall directly into the working area of ​​the buffer assembly. The guide hopper 7 is designed with a rectangular structure, which matches the layout of the two sets of parallel rollers 8 inside and the movement trajectory of the buffer plates 9, which is conducive to the uniform distribution of materials and the realization of the buffering effect.

[0018] The buffer assembly includes two sets of rollers 8, which are movably installed on both sides of the inner cavity of the guide bucket 7. Multiple sets of buffer plates 9 are installed in a circular array on the outer surface of both guide buckets 7. The buffer plates 9 of the two buffer assemblies are staggered, meaning that the buffer plates 9 on one set of rollers 8 are vertically offset from those on the other set, and are not directly aligned. This staggered distribution ensures that the material is alternately blocked and guided by buffer plates 9 in different directions during its descent, achieving effective buffering and avoiding blind spots. In practical applications, the right roller 8 rotates clockwise, and the left roller 8 rotates counterclockwise, guiding the bean products to both sides so that they fall onto the inner wall of the guide bucket 7 for guided discharge, reducing the drop height.

[0019] Furthermore, a drive assembly is also provided on the outer wall of the guide bucket 7. This drive assembly is used to provide power and transmit motion to drive the two sets of rollers 8 to rotate in opposite directions, so that the buffer plate 9 can continuously and dynamically buffer the falling beans. The drive assembly includes two sets of rotating gears 10, which are located on the outside of the guide bucket 7 and are respectively installed at the drive shaft ends of the two sets of rollers 8. The two sets of rotating gears 10 are respectively meshed with a first drive gear 11 and a second drive gear 12. The first drive gear 11 and the second drive gear 12 are meshed. The first drive gear 11 and the second drive gear 12 are both movably installed on the outer wall of the guide bucket 7. A first synchronous pulley 13 is provided on the outside of the second drive gear 12. The first synchronous pulley 13 is connected to the second synchronous pulley 16 through a synchronous belt 14. The second synchronous pulley 16 is driven by the buffer motor 15.

[0020] In use, the buffer motor 15 drives the second drive gear 12 to rotate under the transmission action of the first synchronous pulley 13, the synchronous belt 14 and the second synchronous pulley 16, which in turn drives the first drive gear 11 and the rotating gears 10 on both sides to rotate, thereby driving the two sets of rollers 8 to rotate relative to each other.

[0021] In some examples, a support frame 6 is provided in the middle of the inner side of the fixed frame 1, the guide bucket 7 is fixedly installed in the middle of the inner side of the support frame 6, the buffer motor 15 is fixedly installed on the upper surface of the support frame 6, and the synchronous belt 14 passes through the through hole opened in the inner side of the support frame 6 to drive the first synchronous pulley 13 and the second synchronous pulley 16. The support frame 6 plays a role in stabilizing the installation of the guide bucket 7.

[0022] The working principle of this utility model is as follows: The bean products are fed into the hopper 2. The feeding motor 5 starts, driving the rotating shaft 3 and the spiral feeding blades 4 to rotate, achieving quantitative and controllable feeding. After the material is discharged from the bottom of the hopper 2, it enters the guide hopper 7. At this time, the buffer motor 15 drives the first synchronous pulley 13, the second drive gear 12, the first drive gear 11 and the two sets of rotating gears 10 through the synchronous belt 14, so that the two sets of rollers 8 rotate relative to each other. The multiple sets of buffer plates 9 installed on the rollers 8 rotate accordingly. Since the two sets of buffer plates 9 are staggered, the falling beans will contact and collide with the buffer plates 9 at different levels in sequence. This process gradually converts the gravitational potential energy of the beans into kinetic energy from the collision with the buffer plates 9 and dissipates it. Then, through the rotation and guidance of the rollers 8 and the buffer plates 9, the bean products fall from both sides of the buffer assembly and into the inner wall of the guide hopper 7. Then, they are guided to the discharge port for feeding, thereby significantly reducing their falling speed. After sufficient buffering and deceleration, the beans are finally discharged smoothly from the bottom outlet of the guide hopper 7 and fall into the weighing device or packaging container below, completing the feeding and buffering process.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
