Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically to a high-efficiency mixing device for mooncake fillings. Background Technology

[0002] The 15th day of the eighth lunar month is the traditional Chinese Mid-Autumn Festival, an important festival showcasing the characteristics of Chinese culinary culture. Enjoying various mooncakes is a major part of the festival. Over a long period of evolution and development, mooncakes have formed hundreds of different styles and flavors, including Beijing-style, Suzhou-style, Chaozhou-style, Taiwanese-style, Cantonese-style, Yunnan-style, and Sichuan-style. Among them, Cantonese-style mooncakes are widely popular, with fillings accounting for 40%-80% of the mooncake's weight. Fillings, depending on the ingredients and preparation methods, can be divided into soft fillings, fruit fillings, and dried fruit fillings, among others. Soft fillings are the most exquisite, but also the most labor-intensive and time-consuming to prepare.

[0003] To improve production efficiency, existing mooncake filling production plants typically feed the raw materials into a mixer for mixing. This mixer can quickly break up clumps of raw materials, ensuring that all components of the mooncake filling are thoroughly and evenly mixed. This reduces mixing time and improves the mixing speed and quality of the filling. Such a mixer, which can quickly mix and prepare mooncake fillings, can also be called a high-efficiency mixing device for mooncake fillings.

[0004] However, after completing one production operation using this high-efficiency mixing device for mooncake fillings, the finished filling inside the mixing tank needs to be completely removed before the next mixing operation can be carried out. During this process, the equipment cannot perform mixing operations, thus affecting the production efficiency of the equipment. Therefore, it does not meet the existing requirements. In response, we have proposed a high-efficiency mixing device for mooncake fillings. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency mixing device for mooncake fillings, in order to solve the problems mentioned in the background art, such as the need to completely remove the finished fillings inside the mixing tank after completing one production operation before the next mixing operation can be carried out. During this process, the equipment cannot perform mixing operations, thus affecting the production efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixing device for mooncake fillings, comprising a mixer body, an annular metal shell fixedly provided on one side of the outer surface of the mixer body, a metal shell provided in the middle of the inner side of the annular metal shell, a stepper motor fixedly installed inside the metal shell, the output shaft of the stepper motor being connected to a rotating shaft via a coupling, a circular adjusting plate fixedly connected to the upper end face of the rotating shaft and connected to the annular metal shell via a roller bearing, a mixing tank fixedly provided on both sides of the upper end face of the circular adjusting plate, a discharge valve fixedly installed in the middle of the lower end face of the mixing tank, and the bottom end of the discharge valve passing through the gap between the metal shell and the annular metal shell.

[0007] Preferably, the mixing tank near the main body of the mixer contains a mixing support, and the upper end face of the mixing support is connected to the main body of the mixer.

[0008] Preferably, an L-shaped fixing bracket is fixedly provided on the lower side of the outer surface of the metal shell, and the upper end face of the L-shaped fixing bracket is fixed to the annular metal shell.

[0009] Preferably, the lower end face of the circular adjustment plate is provided with semi-circular positioning grooves on both sides, and a storage groove located inside the annular metal shell is provided below the semi-circular positioning groove. The storage groove contains a spring, and the upper end face of the spring is connected to a metal positioning ball, and the top end of the metal positioning ball is inserted into the interior of the semi-circular positioning groove.

[0010] Preferably, a single-cylinder cylinder is fixedly installed inside the annular metal shell below the metal positioning ball. The piston rod of the single-cylinder cylinder is connected to a metal fixing rod. A circular opening is provided on the outer side of the top end of the metal fixing rod. The circular opening is located in the middle of the upper surface of the metal positioning ball, and a slot is provided above the circular opening, located in the middle of the inner wall of the upper end of the semi-circular positioning groove.

[0011] Preferably, a circular cover plate is provided below the stepper motor on the lower end face of the metal casing, and the metal casing and the circular cover plate are fixed together by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a mixing drum fixed to the upper surface of a circular adjustment plate. When the mixer body is needed for mixing operations, the raw materials for mooncake filling are first added to the second mixing drum from the left. After the mooncake filling inside the mixing drum is mixed, the positions of the two mixing drums are switched using a stepper motor. Once the positions of the two mixing drums are adjusted, the operator can immediately continue the mixing operation using the switched mixing drum. This technical solution reduces the time interval during continuous mixing operations, thereby improving the production efficiency of the equipment. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The mixer body 1 (model SP-5G-TS), stepper motor 3 (model 28BYG30-7A), and spring 15 (model JX110) mentioned in this utility model can all be obtained from the market or through private customization.

[0021] Please see Figures 1 to 4An embodiment of this utility model provides a high-efficiency mixing device for mooncake fillings, comprising a mixer body 1, an annular metal shell 6 fixedly provided on one side of the outer surface of the mixer body 1, a metal shell 2 provided in the middle of the inner side of the annular metal shell 6, a stepper motor 3 fixedly installed inside the metal shell 2, the output shaft of the stepper motor 3 being connected to a rotating shaft 17 via a coupling, a circular adjusting plate 4 fixedly connected to the upper end face of the rotating shaft 17 via a roller bearing, a mixing tank 5 fixedly provided on both sides of the upper end face of the circular adjusting plate 4, a discharge valve 7 fixedly installed in the middle of the lower end face of the mixing tank 5, and the bottom end of the discharge valve 7 passing through the gap between the metal shell 2 and the annular metal shell 6.

[0022] The mixing drum 5 near the main body 1 contains a mixing support, and the upper end of the mixing support is connected to the main body 1. When the equipment is needed to produce mooncake filling, the raw materials for mooncake filling are first added to the mixing drum 5 near the main body 1. During the addition of raw materials, the mixing support is started to perform mixing operations. When the mooncake filling in the second mixing drum 5 from the left is finished being mixed, the mixing support is retracted and the stepper motor 3 is started. The stepper motor 3 can drive the circular adjustment plate 4 connected to it via the rotating shaft 17 to rotate. When the circular adjustment plate 4 rotates, the positions of the two mixing drums 5 fixed on both sides of the upper end of the circular adjustment plate 4 will also change accordingly. After the circular adjustment plate 4 has rotated 180 degrees, the positions of the two mixing drums 5 will be swapped. After the positions of the two mixing drums 5 are adjusted, the operator can immediately continue the mixing operation through the swapped mixing drum 5. The above technical solution can reduce the time interval when the equipment performs continuous mixing operations, thereby improving the production efficiency of the equipment.

[0023] When the equipment resumes mixing and production, the mooncake filling that has already been produced inside the mixing tank 5 is removed through the discharge valve 7.

[0024] An L-shaped fixing bracket 8 is fixedly provided on the lower side of the outer surface of the metal shell 2, and the upper end face of the L-shaped fixing bracket 8 is fixed to the annular metal shell 6. The L-shaped fixing bracket 8 can fix the metal shell 2 and the stepper motor 3 located inside the metal shell 2. By fixing the stepper motor 3, it can prevent the stepper motor 3 from rotating together due to its own rotational force, which would cause the circular adjustment plate 4 to be unable to rotate accurately.

[0025] The circular adjustment plate 4 has semi-circular positioning grooves 9 on both sides of its lower end face. Below the semi-circular positioning grooves 9 is a receiving groove 11 located inside the annular metal shell 6. The receiving groove 11 contains a spring 15. The upper end face of the spring 15 is connected to a metal positioning ball 12, and the top end of the metal positioning ball 12 is inserted into the semi-circular positioning groove 9. When the circular adjustment plate 4 is rotated by the stepper motor 3, the metal positioning ball 12 inserted into the semi-circular positioning groove 9 on the lower end face of the circular adjustment plate 4 will be pushed downward and squeeze the spring 15. After the positions of the two mixing tanks 5 are switched, the two semi-circular positioning grooves 9 will move above the two metal positioning balls 12 again. When the two semi-circular positioning grooves 9 move above the two metal positioning balls 12 again, the reaction force of the squeezed spring 15 can push the two metal positioning balls 12 upward synchronously, so as to insert the metal positioning balls 12 into the semi-circular positioning groove 9 again. This structure can position the two mixing tanks 5 to prevent their position from deviating.

[0026] Below the metal positioning ball 12 is a single-cylinder cylinder 13 fixedly installed inside the annular metal shell 6. The piston rod of the single-cylinder cylinder 13 is connected to a metal fixing rod 14. The outer side of the top end of the metal fixing rod 14 is provided with a circular opening 16, which is located in the middle of the upper end face of the metal positioning ball 12. Above the circular opening 16 is a groove 10 located in the middle of the inner wall of the upper end of the semi-circular positioning groove 9. When the two metal positioning balls 12 are inserted into the two semi-circular positioning grooves 9 again, the single-cylinder cylinder 13 moves upward. Push the metal fixing rod 14. As the metal fixing rod 14 rises, it will pass through the circular opening 16 and be engaged in the slot 10 located in the middle of the upper inner wall of the semi-circular positioning groove 9. By engaging the metal fixing rod 14 in the slot 10, the circular adjusting plate 4 can be fixed. By fixing the circular adjusting plate 4, the mixing tank 5 and the circular adjusting plate 4 can be prevented from moving due to the rotational force during the mixing operation. The above technical solution improves the stability of the equipment during the mixing operation.

[0027] The stepper motor 3 is provided with a circular cover plate located on the lower end face of the metal housing 2, and the metal housing 2 and the circular cover plate are fixed together by screws; the circular cover plate can protect the stepper motor 3, and when the stepper motor 3 fails, the circular cover plate can be removed to repair the stepper motor 3.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
