For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] A powder auxiliary material adding device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.
[0031] Reference Figure 1 , the utility model aims to provide an embodiment of a powder auxiliary material adding device.
[0032] In this embodiment, the adding device includes an inclined feeding screw 1, a feeding pipe 2 mounted on the feeding screw 1, a motor 3 connected to the top of the feeding screw 1, and an auxiliary hopper 4 connected to the bottom of the feeding pipe 2, wherein the auxiliary hopper 4 is provided with a feeding port connected to the interior of the feeding pipe 2, and the top of the feeding pipe 2 is provided with a discharge pipe 5 open downward.
[0033] When using the adding device to add auxiliary materials, add the auxiliary materials into the auxiliary material hopper 4 and cover it with a lid, so that foreign matter falls into the auxiliary materials. Then, start the motor 3, which drives the feeding screw 1 to rotate. With the cooperation of the feeding screw 1 and the feeding tube 2, the auxiliary materials move upward along the feeding tube 2. When the auxiliary materials move to the top of the feeding tube 2, since the feeding tube 2 has an opening in the radial direction, the auxiliary materials fall along the discharge tube 5 under the action of gravity and the extrusion of new auxiliary materials, and are transported to the mixing tank or mixing hopper by the hose connected to the discharge tube 5, thereby completing the auxiliary material adding operation.
[0034] During the powder production process, the main ingredients in the oversized material tank are added to the mixing tank or mixing hopper. The main ingredients are the main components of the powder production, including flour, rice flour, corn flour, etc., while the auxiliary ingredients include various ingredients to enhance the flavor.
[0035] In order to avoid the mixing of different auxiliary materials and affecting the quality of the powder, the adding device is provided with a return material cleaning mechanism, which includes a main material inlet 6 located at the top of the feeding pipe 2 and an upper cover for covering the main material inlet 6. The motor 3 can be reversed to reverse the feeding screw 1. The bottom end of the feeding pipe 2 is provided with a main material outlet and a lower cover 7 for covering the main material outlet.
[0036] When it is necessary to switch products, open the upper cover and the lower cover 7, and put the main material for preparing the powder from the main material inlet 6. At the same time, make the motor 3 drive the feeding screw 1 to rotate in the opposite direction. Therefore, the main material is transported from top to bottom along the feeding pipe 2 and discharged from the main material outlet. In the process of the main material being transported downward, the main material will squeeze out the auxiliary material and remove the remaining auxiliary material to avoid auxiliary material residue. Then, close the upper cover and the lower cover 7, and put the required auxiliary material into the auxiliary material hopper 4, so that the motor 3 can normally drive the feeding screw 1 to feed the material to meet the subsequent powder production needs. At the same time, since the main material is the main component of the powder produced subsequently, it will not cause mixing.

[0039] In some specific embodiments of the present invention, the inner wall of the discharge pipe 5 may be provided with a first recess 9 for accommodating the side edge of the axial insert plate 8 .
[0040] It is easy to understand that, in this embodiment, by providing the first recess 9, the axial insert plate 8 can be limited to prevent the main material from seeping out through the gap between the axial insert plate 8 and the inner wall of the discharge pipe 5. At the same time, it also helps to maintain the shape of the axial insert plate 8 to avoid deformation that affects the activity of the axial insert plate 8.
[0041] In some specific embodiments of the present invention, a first liner 10 may be disposed in the first recess 9 , and when the axial insert plate 8 moves away from the first recess 9 , the first liner 10 rebounds to fill the first recess 9 .
[0042] It is easy to understand that, in this embodiment, by providing the first liner 10 , the gap of the first recess 9 can be filled to reduce powder residue, and the axial insert plate 8 can be positioned to prevent the axial insert plate 8 from moving randomly.
[0043] In some specific embodiments of the present invention, the first gasket 10 can be located on the side wall of the first recess 9, and the first gasket 10 abuts against the axial plug plate 8 along the radial direction of the feeding tube 2. When the axial plug plate 8 is away from the first recess 9, the first gasket 10 fits the two inner walls of the first recess 9 arranged up and down.
[0044] It is easy to understand that in this embodiment, by making the first gasket 10 fit the two upper and lower inner walls of the first recess 9, it is also possible to increase the contact area with the axial plug plate 8 and increase the resistance to moving the axial plug plate 8, so that the axial plug plate 8 remains in the corresponding position, avoiding accidental movement of the axial plug plate 8 and affecting the discharge of the material.
[0045] In some specific embodiments of the present invention, the main material inlet 6 can be provided with a material guide pipe 11, the material guide pipe 11 is open upward, the upper cover is used to cover the material guide pipe 11, and the interior of the material guide pipe 11 is used to position and install the main material hopper.
[0046] It is easy to understand that, in this embodiment, by providing the material guide pipe 11, the main material hopper filled with an appropriate amount of main material can be arranged on the material guide pipe 11, thereby reducing the difficulty of adding the main material.
[0047] In some specific embodiments of the present invention, the upper side edge of the material guiding tube 11 can be rotatably connected to the upper cover, and the lower side edge of the material guiding tube 11 can be snap-connected to the upper cover.
[0048] It is easy to understand that in this embodiment, the upper side edge of the material guide tube 11 is rotatably connected to the upper cover, and the lower side edge of the material guide tube 11 is snap-connected to the upper cover, which also facilitates the sealing of the material guide tube 11 to meet the needs of daily feeding and avoid leakage of auxiliary materials.
[0049] In some specific embodiments of the present invention, the motor 3 can be located on the left and right sides of the top end of the feeding tube 2 .
[0050] It is easy to understand that, by reasonably setting the position of the motor 3, this embodiment does not hinder the arrangement of the material guide pipe 11, and further, facilitates the use of the main material to clean the entire feed pipe 2, thereby improving the cleaning degree.
[0051] In some specific embodiments of the present invention, the adding device may further include a support frame 12 connected to the top end of the feeding pipe 2, the support frame 12 includes a left transverse tube 13 and a right transverse tube 14 connected to the left and right sides of the feeding pipe 2, and the motor 3 is installed in one of the left transverse tube 13 and the right transverse tube 14.
[0052] It is easy to understand that in this embodiment, by providing the support frame 12, the top of the feeding tube 2 can be supported, thereby overcoming the problem that the top of the feeding tube 2 is heavy and easy to tip over.
[0053] At the same time, the arrangement of the left transverse tube 13 and the right transverse tube 14 also provides an installation foundation, facilitates the arrangement of the motor 3, and reduces the difficulty of installation.
[0054] Reference Figure 3 In some specific embodiments of the present invention, the lower cover 7 may include a cover body 15 and an outer ring 16 , and the outer ring 16 is provided with an internal threaded portion 17 connected to the feeding pipe 2 .
[0055] It is easy to understand that in this embodiment, the lower cover 7 includes a cover body 15 and an outer ring 16, and the outer ring 16 has an internal threaded portion 17, which makes it convenient to fix the lower cover 7 by threaded connection, thereby improving the connection strength, preventing it from falling off, and avoiding powder leakage.
[0056] In some specific embodiments of the present invention, the upper cover can be designed with reference to the lower cover 7 , but the material guide tube 11 needs to be adjusted accordingly.
