Description

Technical Field

[0001] This application relates to the technical field of packaging for Tremella polysaccharides, and in particular to a feeding mechanism for weighing finished Tremella polysaccharides. Background Technology

[0002] Tremella polysaccharides, a highly nutritious acidic heteropolysaccharide component of Tremella fuciformis, are currently produced using a unique process to meet diverse consumer preferences. This process first involves precisely extracting the polysaccharide slurry from Tremella fuciformis and then using drying technology to transform it into a manageable and edible sheet-like form. These sheet-like polysaccharides are then meticulously divided into small pieces for single-use consumption. Finally, these small polysaccharide pieces are carefully packaged in bags to ensure hygiene and safety during transportation and storage, while also facilitating consumer carrying and consumption.

[0003] Currently, the weighing of finished Tremella polysaccharide is generally accomplished using a pre-packaging machine. This machine includes a combination scale and infeed and discharge hoppers located above and below it. After precise weighing by the scale, the polysaccharide is discharged from the bottom of the discharge hopper into packaging bags. This method not only enables automated packaging but also allows for the simultaneous quantitative packaging of multiple quantities of Tremella polysaccharide.

[0004] However, in order to reduce the probability of damaging the shape of the flake-shaped tremella polysaccharide during the feeding process, bucket elevators are usually used to feed the bag packaging machine. However, it is difficult to control the amount of tremella polysaccharide fed by the bucket elevator each time. If there is too much, the bag packaging machine cannot accept it, and if there is too little, the efficiency of the bag packaging machine will be affected. Utility Model Content

[0005] This application provides a feeding mechanism for weighing finished Tremella polysaccharide products, which can accurately and reliably complete the feeding of finished Tremella polysaccharide products according to the needs of bag packaging machines, thereby effectively improving the efficiency of weighing and packaging finished Tremella polysaccharide products.

[0006] This application provides a feeding mechanism for weighing finished Tremella polysaccharide products, employing the following technical solution:

[0007] A feeding mechanism for weighing finished Tremella polysaccharide products includes a housing, a drive unit, multiple feeding hoppers, and multiple weighing control devices;

[0008] The shell has an internal cavity, and the bottom of the cavity has an accumulation space for the accumulation of tremella polysaccharides. The bottom of the shell has a feed inlet that communicates with the accumulation space. The top of the cavity has a discharge outlet that is close to and communicates with the bag-feeding packaging machine.

[0009] The driving device includes a driving belt, multiple rotating rollers, and a first driving member; the rotating rollers are rotatably connected to the housing and located in the cavity, the rotation axis of the rotating rollers is perpendicular to the feeding direction of the tremella polysaccharide in the cavity, and the rotation axes of the multiple rotating rollers are parallel to each other; the driving belt is simultaneously wound around the multiple rotating rollers and located in the cavity; the first driving member can drive the driving belt to move along its own winding direction;

[0010] The feeding hopper is disposed on the drive belt, and multiple feeding hoppers are distributed at equal intervals along the movement trajectory of the drive belt; the inside of the feeding hopper has a cavity, and the cavity forms an opening on one side of the feeding hopper for the entry of tremella polysaccharide; as the feeding hopper moves with the drive belt, it can deliver the tremella polysaccharide in the aggregation space through the discharge port.

[0011] Each of the multiple control devices corresponds to one of the multiple feeding hoppers. Each control device includes a weight sensor, a cover plate, and a second drive component. The weight sensor is disposed on the feeding hopper and can sense the weight of the tremella polysaccharide in the cavity. One side of the feeding hopper has a discharge port communicating with the cavity. The cover plate is movably connected to the feeding hopper, and the movement of the cover plate can control the opening and closing of the discharge port. The second drive component can control the movement of the cover plate and is signal-connected to the weight sensor.

[0012] By adopting the above technical solution, the first driving component drives the drive belt to move and drive the feeding hopper through the gathering space. The cavity of the feeding hopper will be filled with Tremella polysaccharide. After the feeding hopper leaves the gathering space, the weight sensor will detect the weight of Tremella polysaccharide in the cavity and control the cover plate to open the discharge port to discharge excess Tremella polysaccharide according to the detection result. This ensures that the amount of Tremella polysaccharide discharged through the discharge port each time can meet the needs of the bag packaging machine. In other words, it can accurately and reliably complete the feeding of Tremella polysaccharide finished product according to the needs of the bag packaging machine, thereby effectively improving the efficiency of weighing and packaging Tremella polysaccharide finished product.

[0013] Optionally, after the tremella polysaccharide in one of the feeding hoppers is discharged through the discharge port, it can fall along the drive belt onto the feeding hopper below and enter the corresponding cavity.

[0014] By adopting the above technical solution, after excess Tremella polysaccharide is discharged from the upper feeding hopper, it can fall along the drive belt to the lower feeding hopper, thus facilitating the replenishment of Tremella polysaccharide in the feeding hopper when it is too low due to excessive discharge or other reasons.

[0015] Optionally, the feeding hopper is provided with a guide member, which is located near the opening of the cavity, and the opening of the cavity for the entry of Tremella polysaccharide is located on the side of the guide member away from the drive belt.

[0016] By adopting the above technical solution, it is possible to further facilitate the discharge of excess Tremella polysaccharide from the upper feeding hopper into the cavity of the lower feeding hopper.

[0017] Optionally, the guide member is rotatably connected to the feeding hopper, and the rotation axis of the guide member is parallel to the rotation axis of the rotating roller;

[0018] When the feeding hopper is located on the side of the drive belt near the feed inlet, the guide rotates to its limit position in the direction of approaching the cavity, at which point the guide can guide the tremella polysaccharide into the cavity;

[0019] When the feeding hopper is located on the side of the drive belt near the discharge port, the guide rotates to its limit position in the direction away from the cavity. At this time, the guide can guide the tremella polysaccharide to be discharged through the discharge port.

[0020] By adopting the above technical solution, the guide can rotate and adjust itself under its own gravity according to the position of the feeding hopper, so as to guide the tremella polysaccharide discharged from the upper feeding hopper into the feeding hopper during the process of transporting tremella polysaccharide, and guide the tremella polysaccharide out of the feeding hopper during the process of discharging tremella polysaccharide through the discharge port.

[0021] Optionally, a flexible protective layer is provided between both sides of the guide member and the feeding hopper, and the protective layer can be unfolded and retracted as the guide member rotates.

[0022] By adopting the above technical solution, the baffle can facilitate the entry of Tremella polysaccharide into the cavity through the opening of the cavity under the guidance of the guide, and at the same time, it can facilitate the discharge of Tremella polysaccharide through the discharge port under the guidance of the guide, reducing the probability that Tremella polysaccharide will leave from both sides of the guide and fall back into the accumulation space during this process.

[0023] Optionally, when the guide member rotates to its limit position in the direction closer to the cavity, the end of the guide member away from its own rotation axis is lower than the end of the guide member closer to its own rotation axis.

[0024] By adopting the above technical solution, after the tremella polysaccharide falls onto the guide, it can move along the surface of the guide towards the opening of the cavity under its own gravity, thereby making it easier for excess tremella polysaccharide in the upper feeding hopper to be replenished into the lower feeding hopper.

[0025] Optionally, the guide member has an arc-shaped structure, the arc trajectory of which is perpendicular to its own rotation axis, and the arc-shaped flare faces the cavity.

[0026] By adopting the above technical solution, the guiding effect of the guide component on Tremella polysaccharide can be further improved, making the process of Tremella polysaccharide entering the cavity through the guide component more convenient and reliable, and making the process of Tremella polysaccharide being discharged from the outlet through the guide component more convenient and reliable.

[0027] Optionally, when the feeding hopper is located on the side of the drive belt near the feed inlet, the discharge outlet is located at the bottom of the feeding hopper.

[0028] By adopting the above technical solution, the polysaccharide of Tremella fuciformis in the cavity can be conveniently discharged through the discharge port, thereby improving the efficiency of discharging excess polysaccharide of Tremella fuciformis from the feeding hopper.

[0029] Optionally, the cover plate is rotatably connected to the feeding hopper, and the rotation axis of the cover plate is parallel to the rotation axis of the rotating roller; when the feeding hopper is located on the side of the drive belt near the feed inlet, the rotation axis of the cover plate is located at the top of the feeding hopper.

[0030] By adopting the above technical solution, the opening and closing of the discharge port can be easily controlled by the cover plate, making the control of whether the tremella polysaccharide in the cavity is discharged more sensitive, and at the same time, the discharged tremella polysaccharide can be easily moved downward along the drive belt.

[0031] In summary, this application includes at least one of the following beneficial effects:

[0032] 1. It can accurately and reliably complete the feeding of tremella polysaccharide products according to the needs of bag packaging machines, thereby effectively improving the efficiency of weighing and packaging tremella polysaccharide products;

[0033] 2. The lower feeding hopper can collect the tremella polysaccharide discharged from the upper feeding hopper, allowing the quantity control device to adjust the weight of the tremella polysaccharide in the feeding hopper multiple times, thereby effectively improving the quantity control effect of the quantity control device and ensuring that the weight of the tremella polysaccharide in the feeding hopper meets the requirements.

[0034] 3. It can guide the tremella polysaccharide into and out of the cavity, thus making it easier for the tremella polysaccharide discharged from the feeding hopper to be replenished into the feeding hopper below, and for the tremella polysaccharide in the feeding hopper to be discharged through the outlet.

[0041] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0042] This application discloses a feeding mechanism for weighing finished Tremella polysaccharide, which is used in conjunction with a pre-packaging machine to feed a certain weight of Tremella polysaccharide into the pre-packaging machine according to its requirements.

[0043] Reference Figure 1 and Figure 2 The feeding mechanism for weighing finished Tremella polysaccharide includes a housing 2, a drive unit 3, multiple feeding hoppers 4, and multiple weighing control devices 5. The housing 2 provides shielding for other components of the feeding mechanism, effectively reducing the impact of external impurities (such as dust) on the quality of the conveyed Tremella polysaccharide. The drive unit 3 provides power for the conveying process. The feeding hoppers 4 hold the Tremella polysaccharide for conveying. The weighing control devices 5 regulate the weight of the Tremella polysaccharide in the feeding hoppers 4, ensuring that the weight meets the requirements of the bag packaging machine 1. In this embodiment, since the bag packaging machine 1 is prior art, it will not be described in detail here, and only a brief representation is given in the accompanying drawings.

[0044] The shell 2 has a rectangular parallelepiped structure. Inside the shell 2, there is a cavity 21, which is also rectangular parallelepiped. The length of the cavity 21 is parallel to the length of the shell 2. The shell 2 is installed and fixed in an inclined position along its length. Its inclined lower end is located on one side of the bag packaging machine 1, and its inclined upper end is fixedly connected to the top of the bag packaging machine 1. The bottom of the shell 2, away from the bag packaging machine 1, has an inlet 22 for the Tremella polysaccharide to enter the cavity 21. Near the inlet 22, the cavity 21 has an accumulation space 24 for the Tremella polysaccharide to accumulate. The inlet 22 communicates with the accumulation space 24. The top of the shell 2, near the bag packaging machine 1, has an outlet 23 for the Tremella polysaccharide to be transported to the bag packaging machine 1. The top of the cavity 21 communicates with the bag packaging machine 1 through the outlet 23.

[0045] The drive unit 3 includes multiple rotating rollers 31, a drive belt 32, and a first drive element 33.

[0046] The rotating roller 31 has a cylindrical structure. It is rotatably connected to the housing 2 and located in the cavity 21. The rotation axis of the rotating roller 31 is horizontal and perpendicular to the length direction of the housing 2, and its rotation axis coincides with its own axis. In this embodiment, the driving device 3 preferably includes two rotating rollers 31, and preferably the two rotating rollers 31 are distributed along the length direction of the housing 2, located in the cavity 21 near the inlet 22 and the outlet 23, respectively.

[0047] The drive belt 32 has a strip structure with the ends connected, and is flexible and can be bent and wound freely. The drive belt 32 is simultaneously wound and installed on two rotating rollers 31 and is in a taut state. At this time, the rotation of either rotating roller 31 relative to the housing 2 can drive the other rotating roller 31 to rotate synchronously and in the same direction through the drive belt 32.

[0048] The first driving component 33 is fixedly installed on the outside of the housing 2 and can drive a rotating roller 31 to rotate relative to the housing 2. In this embodiment, the first driving component 33 is preferably a servo motor, and its output end passes through the housing 2 and is fixedly connected to the rotating roller 31.

[0049] Reference Figure 2 and Figure 3 The feeding hopper 4 is fixedly installed on the drive belt 32 and located on the outside of the drive belt 32. In this embodiment, it is preferable that multiple feeding hoppers 4 are evenly distributed on the drive belt 32 along the winding direction of the drive belt 32; and preferably when the feeding hopper 4 is located on both sides of the drive belt 32, the end face of the feeding hopper 4 near the drive belt 32 will remain in contact with the surface of the drive belt 32.

[0050] Reference Figure 4 and Figure 5The inside of the feeding hopper 4 has a cavity 41 for holding Tremella polysaccharide. The feeding hopper 4 has an opening on one side for Tremella polysaccharide to enter and exit the cavity 41. When the feeding hopper 4 is located on the side of the drive belt 32 away from the discharge port 23, the opening of the cavity 41 is located above the cavity 41; when the feeding hopper 4 is located on the side of the drive belt 32 close to the discharge port 23, the opening of the cavity 41 is located below the cavity 41.

[0051] As the feeding hopper 4 moves within the cavity 21 along with the drive belt 32, it passes through the collection space 24. During this process, the tremella polysaccharide located in the collection space 24 enters the cavity 41 through the opening, facilitating the filling of the hopper cavity 41 with the tremella polysaccharide. As the feeding hopper 4 moves from the side of the drive belt 32 away from the discharge port 23 to the side of the drive belt 32 closer to the discharge port 23, the feeding hopper 4 will flip over. During this process, the tremella polysaccharide in the cavity 41 will first leave the feeding hopper 4 through the opening of the cavity 41, and then leave the shell 2 through the discharge port 23. In this embodiment, it is preferable that the feeding hopper 4 is completely submerged in the tremella polysaccharide located in the collection space 24 during the process of passing through the collection space 24.

[0052] Reference Figure 3 and Figure 5 Multiple control devices 5 correspond one-to-one with multiple feeding hoppers 4, which can respectively adjust the weight of the corresponding feeding hopper 4 so that the weight of the tremella polysaccharide in the corresponding cavity 41 meets the requirements of the bag packaging machine 1.

[0053] The weighing control device 5 includes a weight sensor 51, a cover, and a second drive unit 53. The weight sensor 51 is used to weigh the mass of the Tremella polysaccharide in the corresponding cavity 41; the cover and the second drive unit 53 work together to enable the feeding hopper 4 to discharge excess Tremella polysaccharide from the cavity 41.

[0054] A weight sensor 51 is fixedly installed on the feeding hopper 4 and can weigh the tremella polysaccharide in the cavity 41. In this embodiment, the weight sensor 51 preferably includes a signal control module located outside the feeding hopper 4 and a weight sensing module distributed at the bottom of the feeding hopper 4. After the weight sensing module weighs the tremella polysaccharide inside the cavity 41 at the bottom of the feeding hopper 4, the signal control module can acquire the corresponding data and compare it with its own preset data, and make corresponding actions based on the comparison results. Since the weight sensor 51 with the above functions is common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0055] The feeding hopper 4 has a discharge port 42 at the end away from its own opening for discharging tremella polysaccharides. The cover is movably mounted on the feeding hopper 4 near the discharge port 42, and the opening and closing of the discharge port 42 can be controlled during the movement of the cover. In this embodiment, it is preferable that when the feeding hopper 4 is located on the side of the drive belt 32 away from the discharge port 23, the discharge port 42 is located at the bottom of the feeding hopper 4; and preferably, the cover is rotatably connected to the feeding hopper 4.

[0056] The rotation axis of the cover is parallel to the rotation axis of the rotating roller 31. When the feeding hopper 4 is located on the side of the drive belt 32 away from the discharge port 23, the rotation axis of the cover is located above the discharge port 42. When the cover rotates to the limit position away from the feeding hopper 4, the discharge port 42 will be open. The tremella polysaccharide in the cavity 41 can leave the cavity 41 through the discharge port 42 under the guidance of the cover plate 52 and contact the drive belt 32. When the cover rotates to the limit position close to the feeding hopper 4, the discharge port 42 will be closed. After the cover covers the discharge port 42, it will keep its end face in contact with the feeding hopper 4.

[0057] The second driving component 53 is fixedly installed on the outside of the feeding hopper 4 and can drive the cover to rotate relative to the feeding hopper 4. In this embodiment, the second driving component 53 is preferably a servo motor, and its output end is fixedly connected to the cover plate 52.

[0058] The weight sensor 51 is connected to the corresponding second drive unit 53. When the weight sensor 51 weighs and determines that the weight of the tremella polysaccharide in the cavity 41 exceeds the preset value, the weight sensor 51 will control the corresponding second drive unit 53 to drive the cover plate 52 to rotate and open the discharge port 42, so that the excess tremella polysaccharide in the cavity 41 is discharged until the weight of the tremella polysaccharide in the cavity 41 is less than or equal to the preset value; at other times, the second drive unit 53 will drive the cover plate 52 to keep the discharge port 42 closed.

[0059] Reference Figure 4 and Figure 5 When the discharge port 42 is opened, the tremella polysaccharide discharged through the discharge port 42 will move downward along the surface of the drive belt 32 away from the discharge port 23, and can fall onto the feeding hopper 4 located below it and enter the lower cavity 41 through the opening of the cavity 41 to replenish it. This can effectively reduce the probability that the weight of tremella polysaccharide in the cavity 41 will be too different from the preset value due to excessive discharge of tremella polysaccharide from the feeding hopper 4. The replenished tremella polysaccharide can make the weight of tremella polysaccharide in the cavity 41 of the feeding hopper 4 as close as possible to the preset value.

[0060] Furthermore, to facilitate the addition of Tremella polysaccharide into the cavity 41 and to facilitate the pouring out of Tremella polysaccharide in the cavity 41, a guide 43 is preferably installed at the end of the feeding hopper 4 away from the discharge port 42.

[0061] The guide member 43 is installed at the opening of the cavity 41 and is rotatably connected to the feeding hopper 4, and the rotation axis of the guide member 43 is parallel to the rotation axis of the cover plate 52; the rotation axis of the guide member 43 is located on the side of itself close to the drive belt 32, and is close to the side of the feeding hopper 4 close to the drive belt 32.

[0062] The guide member 43 has limitations during its rotation relative to the feeding hopper 4. When the guide member 43 rotates to its limit position towards the cavity 41, it is located in the cavity 41 and tilts away from the drive belt 32 towards the cavity 41. If the feeding hopper 4 is located on the side of the drive belt 32 away from the discharge port 23, the guide member 43 can guide the tremella polysaccharide falling from above onto the feeding hopper 4 through the opening of the cavity 41 on the side of the guide member 43 away from its own rotation axis into the cavity 41. When the guide member 43 rotates to its limit position away from the cavity 41, it will leave the cavity 41 and tilt away from the drive belt 32 towards the cavity 41. If the feeding hopper 4 is located on the side of the drive belt 32 near the discharge port 23, the guide member 43 can guide the tremella polysaccharide in the cavity 41 smoothly through the discharge port 23 into the bag packaging machine 1. In this embodiment, the preferred guide member 43 can rotate relative to the corresponding feeding hopper 4 under its own gravity according to its position on the drive belt 32. When the feeding hopper 4 is located on the side of the drive belt 32 away from the discharge port 23, the guide member 43 will rotate to the limit position in the direction closer to the cavity 41 under its own gravity. When the feeding hopper 4 is located on the side of the drive belt 32 close to the discharge port 23, the guide member 43 will rotate to the limit position in the direction away from the cavity 41 under its own gravity. And when the feeding hopper 4 is located on the drive belt 32 close to the discharge port 23, the guide member 43 will be in the state of rotating to the limit position in the direction away from the cavity 41.

[0063] Furthermore, to facilitate the replenishment of Tremella polysaccharide into the cavity 41, and to facilitate the discharge of Tremella polysaccharide from the cavity 41 through the discharge port 23, it is preferable that both sides of the guide member 43 are equipped with protective layers 44.

[0064] The protective layer 44 is flexible and can be bent and deformed freely. Both ends of the protective layer 44 are fixedly connected to one side of the guide member 43 along its own axis of rotation and the side of the feed hopper 4 near the opening, respectively. In this embodiment, the protective layer 44 is preferably made of elastic fabric.

[0065] When the guide 43 rotates to its limit position towards the cavity 41, both protective layers 44 are located inside the cavity 41. At this time, the two protective layers 44 allow the tremella polysaccharide added to the cavity 41 to move smoothly along the guide 43 into the cavity 41. When the guide 43 rotates to its limit position away from the cavity 41, both protective layers 44 are located outside the cavity 41. At this time, the two protective layers 44 allow the tremella polysaccharide leaving the cavity 41 to move smoothly along the guide 43 and be discharged through the discharge port 23, reducing the probability that the tremella polysaccharide will leave from both sides of the guide 43 and fall back into the aggregation space 24.

[0066] The implementation principle of the feeding mechanism for weighing finished Tremella polysaccharide product in this application embodiment is as follows:

[0067] Based on the weight of Tremella polysaccharide required for one run of the bag packaging machine 1, after setting the value for the quantity control device 5, a certain amount of Tremella polysaccharide is fed into the cavity 21 through the feed inlet 22, and the Tremella polysaccharide will accumulate in the aggregation space 24.

[0068] During the process of the first driving component 33 driving the driving belt 32, multiple feeding hoppers 4 can be driven to circulate in the cavity 21. As the feeding hoppers 4 pass through the collection space 24, the tremella polysaccharide in the collection space 24 will enter the cavity 41 through the opening. Afterwards, as the feeding hoppers 4 move on the side of the driving belt 32 away from the discharge port 23, the measuring device 5 will compare the weight of the tremella polysaccharide in the cavity 41 with a preset value. When the weight of the tremella polysaccharide in the cavity 41 exceeds the preset value, the discharge will be controlled. When the opening 42 is opened, excess Tremella polysaccharide in the cavity 41 is discharged. The discharged Tremella polysaccharide can enter the cavity 41 of the feeding hopper 4 below through the surface of the drive belt 32 and the lower guide 43 to replenish it. This cycle continues until the weight of Tremella polysaccharide in the cavity 41 is as close as possible to the preset value. When the feeding hopper 4 moves to a position close to the discharge port 23, the Tremella polysaccharide in the cavity 41 will leave the cavity 41 along the guide 43 under its own gravity and enter the bag packaging machine 1 through the discharge port 23, thereby achieving precise feeding.

[0069] 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.
