Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0036] In conjunction with the instruction manual Figure 1 To Attachment Figure 4 It can be known that the laundry detergent premixing device provided by the utility model mainly includes the following parts or components: a premixing tank 10 , a first rotating shaft 11 , a second rotating shaft 12 , a first stirring shaft 13 , a second stirring shaft 14 , and a third stirring shaft 141 .

[0037] In the utility model, a feed port 101 is provided on the premixing tank 10; a first rotating shaft 11 is rotatably arranged vertically in the premixing tank 10, and a mounting box 111 is arranged at the lower end thereof; a second rotating shaft 12 is nested in the first rotating shaft 11, and rotates alternately forward and reversely under the drive of the driving component 20, and the second rotating shaft 12 drives the first rotating shaft 11 to rotate in the opposite direction to the second rotating shaft 12 through the connecting component 30, and the lower end of the second rotating shaft 12 passes through the top of the mounting box 111; a first stirring shaft 13 is horizontally arranged in the mounting box 111, and is perpendicular to the first rotating shaft 11, and the first stirring shaft 13 is arranged horizontally in the mounting box 111, and is perpendicular to the first rotating shaft 11. The first bevel gear 132 on the third shaft is meshed with the second bevel gear 121 at the lower end of the second rotating shaft 12. Both ends of the first stirring shaft 13 pass through both sides of the installation box 111 and are provided with first stirring paddles 131; the second stirring shaft 14 and the third stirring shaft 141 are arranged in parallel on both sides of the first rotating shaft 11 above the first stirring shaft 13, and the second stirring shaft 14 and the third stirring shaft 141 are both provided with second stirring paddles 142. The driving component 20 drives the second stirring shaft 14 to rotate through the first transmission component 40, and the second stirring shaft 14 drives the third stirring shaft 141 to rotate through the second transmission component 50.

[0038] During operation, the material is sent from the feed port 101 to the premixing tank 10, the driving component 20 drives the second rotating shaft 12 to rotate alternately forward and reverse, the second rotating shaft 12 drives the second bevel gear 121 to rotate alternately forward and reverse, while the second rotating shaft 12 rotates alternately forward and reverse, the first rotating shaft 11 is driven to rotate in the opposite direction thereto through the connecting component 30, the first rotating shaft 11 drives the installation box 111 to rotate in the same direction, the installation box 111 drives the first stirring shaft 13 to revolve along the first rotating shaft 11, and because the installation box 111 rotates in opposite directions to the second rotating shaft 12, the first bevel gear 132 is meshed with the second bevel gear 121 and drives the first stirring shaft 13 to revolve along the first rotating shaft 11. The first stirring shaft 13 is driven to rotate, and the first stirring paddle 131 on the first stirring shaft 13 stirs the material at the bottom of the premixing tank 10. The driving component 20 drives the second stirring shaft 14 to rotate through the first transmission component 40. The second stirring shaft 14 drives the third stirring shaft 141 to rotate through the second transmission component 50. The second stirring shaft 14 and the third stirring shaft 141 stir the material above the first stirring shaft 13 through the second stirring paddle 142 respectively. The first stirring shaft 13, the second stirring shaft 14, and the third stirring shaft 141 stir the material at the same time, which can effectively stir the area in the premixing tank 10 and better mix the materials evenly.

[0039] The second stirring paddle 142 is spiral-shaped. The spiral agitator generates high shear force, which helps to effectively disperse and stir the materials and ensure a uniform mixing effect.

[0040] As an embodiment, in conjunction with the attached Figure 2It can be seen that the driving assembly 20 includes a first motor 21 disposed on the premixing tank 10, on which a wheel disc 22 is disposed, and a first guide column 221 is eccentrically disposed on the wheel disc 22; a first rack 23 is slidably disposed horizontally above the premixing tank 10, a first long slot hole 231 disposed at the end of the first rack 23 is slidably connected to the first guide column 221, and the first rack 23 is meshed with a first gear 122 at the upper end of the second rotating shaft 12 that passes through the top of the premixing tank 10. The first motor 21 drives the wheel disc 22 to rotate, and the first guide column 221 on the wheel disc 22 cooperates with the first long slot hole 231 at the end of the first rack 23 to drive the first rack 23 to move horizontally, and the first rack 23 drives the second rotating shaft 12 to rotate alternately forward and reverse through the first gear 122.

[0041] As an embodiment, in conjunction with the attached Figure 2 It can be seen that the connecting assembly 30 includes a third bevel gear 31, which is arranged on the second rotating shaft 12; the fourth bevel gear 32 is arranged on the first rotating shaft 11 and is arranged opposite to the third bevel gear 31; the fifth bevel gear 33 is rotatably arranged above the premixing tank 10, and is meshed with the third bevel gear 31 and the fourth bevel gear 32 respectively.

[0042] When the second rotating shaft 12 rotates alternately forward and reverse, it drives the third bevel gear 31 to rotate alternately forward and reverse. The third bevel gear 31 drives the fourth bevel gear 32 to rotate in the opposite direction of the third bevel gear 31 through the fifth bevel gear 33. The fourth bevel gear 32 drives the first rotating shaft 11 to rotate in the opposite direction of the second rotating shaft 12.

[0043] In this embodiment, in conjunction with the attached Figure 2 , Attachment Figure 3 It can be seen that the first transmission assembly 40 includes a first pulley 41, which is arranged on the second stirring shaft 14, and the first pulley 41 is connected to the outer circumferential surface of the wheel disc 22 through a first belt 42. The second transmission assembly 50 includes two second pulleys 51, which are respectively arranged on the second stirring shaft 14 and the third stirring shaft 141, and the two second pulleys 51 are connected through a second belt 52.

[0044] When the wheel disc 22 rotates, the first belt 42 drives the first pulley 41 to rotate, and the first pulley 41 drives the second stirring shaft 14 to rotate. When the second stirring shaft 14 rotates, the two second pulleys 51 and the second belt 52 drive the third stirring shaft 141 to rotate in the same direction.

[0045] As an embodiment, in conjunction with the attached Figure 4It can be seen that a dredging assembly 60 is provided in the feed port 101 for dredging the materials in the feed port 101. The dredging assembly 60 includes a dredging rod 61 arranged vertically in the feed port 101, the upper end of the dredging rod 61 is connected to the rotating shaft of the piston rod end of the hydraulic cylinder 62, and the lower end of the dredging rod 61 is provided with a tapered rod 63 after passing through the support plate above the premixing tank 10; a rotating sleeve 64 is rotatably provided on the support plate and is coaxial with the dredging rod 61, and the guide groove on the rotating sleeve 64 is slidably connected with the guide key 611 provided on the dredging rod 61 along its axial direction; a second motor 65 is provided on the premixing tank 10, and a second gear 651 provided thereon is meshed with a third gear 641 on the rotating sleeve 64.

[0046] The raw materials of laundry detergent are mostly powdered. When the powdered materials enter the premixing tank 10 from the feed port 101, it is very easy to form an "arch bridge" phenomenon, thereby causing the feed port 101 to be blocked. Therefore, the dredging component 60 is needed to dredge. During dredging, the hydraulic cylinder 62 drives the dredging rod 61 to rise and fall, and at the same time, the second motor 65 drives the second gear 651 to rotate, and the second gear 651 drives the third gear 641 to rotate, and the third gear 641 drives the rotating sleeve 64 to rotate. The rotating sleeve 64 drives the dredging rod 61 to rotate through the cooperation of the guide groove and the guide key 611. Because the upper end of the dredging rod 61 is connected to the rotating shaft at the end of the piston rod of the hydraulic cylinder 62, the rotation of the dredging rod 61 will not cause interference when it is raised and lowered, and the tapered rod 63 at the lower end of the dredging rod 61 dredges the feed port 101.

[0047] Specifically, an openable and closable sealing door can be installed on the feed port 101. After unblocking, when the material completely enters the premixing roller, the unblocking rod 61 rises until it is separated from the feed port 101, and then the sealing door is closed. This can effectively mix the material in the premixing tank 10 and prevent the material from spilling out of the feed port 101 when being stirred.

[0048] It should be noted that, in this patent application, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
