[0042] In this embodiment, the material feeding mechanism 2 is located corresponding to the feeding station, and the incoming packaged material can be placed in the material feeding mechanism 2, and the stirring mechanism 3 is used to stir the material, so that the discharge is more uniform and easy to use; moreover, a material guiding mechanism 4 is provided, and the material can be transferred from the material feeding mechanism 2 to the stirring mechanism 3 through the material guiding mechanism 4, and the material guiding mechanism 4 includes a material guiding cylinder 41 and a spiral push rod, and the spiral push rod can be wrapped therein by the material guiding cylinder 41, so that the material can be prevented from spilling during the material conveying, and the material is conducted by the spiral push rod, and there is no conveying gap, which has a better conveying effect for powdered materials; moreover, the setting height of the first outlet of the material feeding mechanism 2 is smaller than the height of the second inlet of the stirring mechanism 3, and the spiral push rod can better realize the conveying in the height difference direction to achieve a better conveying effect, and the material is conveyed in a closed state throughout the process, and the material is not easy to spill, which better ensures the cleanliness of the spiral feeding device 100 and better protects the working environment.
[0043] Among them, the frame 1 can be set as an integral whole, or the frame 1 can be composed of a plurality of small brackets. The frame 1 can be broadly defined as the ground, or the frame 1 can be a flat plate, a support, or a rod structure. There are many settings for the frame 1, which are not specifically limited here. It should be noted that when the spiral feeding device 100 is working normally, the loading station and the stirring station can be arranged in the left and right direction, or in the front and back direction, or at intervals in other directions along the horizontal plane. Preferably, in the case of Figure 1 In the direction shown, the stirring station is located to the right of the loading station. The description of the relevant directions in this utility model can be referred to in this way.
[0044] Specifically, for the material feeding mechanism 2, combined with Figure 1 and Figure 2 As shown, the material feeding mechanism 2 includes a feeding bracket 21 and a feeding funnel 22. The feeding bracket 21 is slidably mounted on the machine frame 1; the feeding funnel 22 is mounted on the feeding bracket 21, and the first outlet is located at the constricted end of the feeding funnel 22. The feeding bracket 21 is arranged in a square frame shape, and the feeding funnel 22 is fixed to the feeding bracket 21. Rollers are provided at the bottom of the feeding bracket 21, which facilitate the movement of the feeding bracket 21 and the feeding funnel 22, thereby facilitating the adjustment of the connection between the material feeding mechanism 2 and the material guide mechanism 4. It also facilitates disassembly and replacement after the size of the material guide mechanism 4 or the material feeding mechanism 2 changes, providing better adaptability.
[0045] Furthermore, the screw push rod includes a rotating shaft and a spiral blade disposed on the rotating shaft; the material guide mechanism 4 also includes a spiral drive structure 42 connected to the rotating shaft, the spiral drive structure 42 being used to drive the rotating shaft to rotate so that the material can be conveyed from the first outlet to the second inlet along the spiral blade. The spiral drive structure 42 drives the rotating shaft to rotate, driving the spiral blade to rotate around the rotating shaft, so that the material can be moved along the axial direction of the rotating shaft and along the rotation direction of the spiral blade under the action of the spiral blade, thereby transferring the material from the first outlet to the second inlet. The rotating shaft and the spiral blade can be integrally arranged, with no gap between the rotating shaft and the spiral blade, thereby achieving a better conveying effect for powdered materials.
[0046] Furthermore, the material guide barrel 41 is generally cylindrical and tilted upward from the first outlet toward the second inlet. This allows material to move upward along the axis of the rotating shaft, conveying it to the elevated second inlet. Compared to traditional conveyor belts, the spiral blades act on the material, preventing it from slipping, thereby improving material transport from low to high locations. This makes pouring material into the first inlet of the loading hopper 22 more labor-saving and convenient, either manually or mechanically.
[0047] Preferably, the screw push rod is configured as a Jiaolong shaft, which can be directly purchased and has a lower production cost.
[0048] Since the outer circumference of the guide barrel 41 is arranged in an arc shape, in order to make the first outlet and the guide barrel 41 better sealed and connected. The discharge end face of the first outlet can be arranged at an angle and parallel to the axial direction of the guide barrel 41. The outer circumference of the guide barrel 41 is provided with an inlet, and the first outlet is arranged in close contact with the inlet. Among them, a first outlet is arranged at an angle on one side of the bottom of the feeding funnel 22. The first outlet is arranged in a roughly square shape. The inner side walls of the feeding funnel 22 are inclined toward the first outlet, so that the material can flow better toward the direction of the first outlet after entering the feeding funnel 22. The shape of the inlet is adapted to the shape of the first outlet, or one of the first outlet and the inlet can be sleeved inside the other, so that the first outlet and the inlet are tightly docked to avoid material leakage.
[0049] Preferably, a sealing member is provided between the first outlet and the feed inlet to ensure a better sealing effect. The sealing member can be provided as a sealing ring or a sealing sleeve, etc., to be sleeved between the joint of the first outlet and the feed inlet.
[0050] Specifically, for the spiral drive structure 42, if Figure 2 As shown in the figure, the spiral drive structure 42 includes a driving mounting plate 422, a spiral driver 421, an active transmission wheel 423, a driven transmission wheel 424 and a transmission belt 425. The driving mounting plate 422 is provided on the frame 1 and is parallel to the extension direction of the guide barrel 41. The driving mounting plate 422 can move relative to the frame 1 toward and away from the first outlet; the spiral driver 421 is provided on the driving mounting plate 422; the active transmission wheel 423 is connected to the spiral driver 421; the driven transmission wheel 424 is connected to the spiral push rod and is located on the outside of the guide barrel 41; the transmission belt 425 connects the active transmission wheel 423 and the driven transmission wheel 424. The spiral driver 421 can be set as a driving motor, which drives the active transmission wheel 423 to rotate through the spiral driver 421, and then drives the driven transmission wheel 424 to rotate together through the transmission belt 425, so that the transmission shaft can rotate together, so that the material falling into the feeding port from the first outlet can move toward the upper end of the guide barrel 41 under the pushing action of the spiral blade to be transmitted to the second inlet.
[0051] Moreover, if Figure 2As shown in , a first long hole 4221 is provided on the drive mounting plate 422, and the first long hole 4221 is provided to extend in a radial direction parallel to the material guide barrel 41. The drive mounting plate 422 is generally flat and is disposed close to the material guide barrel 41. By providing the first long hole 4221, the distance between the drive mounting plate 422 and the material guide barrel 41 along their radial directions can be adjusted, thereby adjusting the distance between the active transmission wheel 423 and the driven transmission wheel 424. The drive belt 425 can be kept in a taut state, and the drive belt 425 can be adapted to the needs of various drive wheels of different sizes. Even if the size of the spiral driver 421, the active transmission wheel 423, or the driven transmission wheel 424 changes, the installation requirements can still be met, thus having a wider range of applications.
[0052] In addition, combined Figure 1 and Figure 2 As shown, the material guide mechanism 4 also includes a connecting sleeve 426. The material guide barrel 41 includes a material guide body 411, an extension section 412 protruding from the peripheral sidewall of the material guide body 411, and a discharge port provided on the extension section 412, with the discharge port facing downward. The connecting sleeve 426 connects the second inlet and the discharge port. The screw push rod is disposed within the material guide barrel 41. The extension section 412 is positioned near the top of the material guide barrel 41 and extends toward the front to facilitate connection with the second inlet. The connecting sleeve 426 supports and secures the material guide barrel 41 while forming a conductive section, allowing material discharged from the discharge port to enter the second inlet more effectively.
[0053] Among them, the stirring mechanism 3 includes a stirring drum and a stirring shaft that rotates inside the stirring drum. The material falling into the stirring drum from the second inlet can be stirred under the rotation of the stirring shaft to avoid material agglomeration. After stirring, the material can fall out from the second outlet.
[0054] Furthermore, the screw feeding device 100 further includes a weighing mechanism 5 and a powder discharge mechanism 6. The weighing mechanism 5 is used to weigh the powder discharged from the stirring mechanism 3. The powder discharge mechanism 6 is connected to the second outlet and is used to transfer the powder stirred by the stirring mechanism 3 from the second outlet to the weighing mechanism 5. This allows for quantitative weighing of the stirred powder, making it more accurate for use.
[0055] The powder feeding mechanism 6 includes a feeding barrel and a conveying screw arranged in the feeding barrel. The conveying screw can be set as a dragon shaft to better convey the stirred material to the weighing mechanism 5 for weighing.
[0056] The spiral feeding device 100 is in a closed transmission channel during the entire material transmission process, which can better seal the material and prevent it from being scattered. In addition, the material is not likely to fall into the device during the transmission process, and the entire spiral feeding device 100 will not get stuck, making it easier to clean.
[0057] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
