Description

Technical Field

[0001] The utility model relates to the field of pre-packaged food processing and mixing, in particular to a mixing device used for pre-packaged food processing. Background Art

[0002] Pre-packaged food refers to food that is pre-packaged or made in packaging materials and containers, including food that is pre-packaged or pre-made in packaging materials and containers and has a uniform quality or volume labeling within a certain quantity limit. Mixing and stirring are essential steps in the processing of pre-packaged food.

[0003] During use, the existing pre-packaged food processing and stirring device has a single stirring direction, resulting in poor mixing effect. At the same time, the motor rotates synchronously when the tank is stirred, which easily causes cable entanglement and poses certain safety hazards. Therefore, in order to improve the mixing effect, some technologies have proposed relevant technical structures to assist the use of the mixing device. For example, there is a utility model patent with application number 202223008215.7, which proposes a raw material stirring device for pre-packaged food production. A stirring mechanism is arranged inside the stirring tank mechanism to facilitate the full stirring of the raw materials and seasonings. The first stirring frame and the second stirring frame stir in different reverse directions to effectively improve the mixing effect and improve the stirring efficiency of the raw materials. At the same time, a supporting mechanism is used to drive the stirring tank mechanism to rotate, which facilitates the stirring mechanism to stir the raw materials at the bottom, further improving the efficiency of food stirring processing.

[0004] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is conducive to improving the mixing effect. However, when the raw materials are stirred inside the mixing device, the rotation of the stirring device drives the movement of the raw materials inside the tank body, which can easily cause the raw materials to adhere to the inner wall of the tank body and form a hanging wall. The raw materials after hanging on the wall cannot be mixed with the raw materials inside the tank body, which will cause uneven mixing of the raw materials, thereby affecting the mixing effect of the raw materials.

[0005] In this regard, the Chinese utility model patent with application number 202321465869.4 proposes a mixing device for pre-packaged food processing, but there are still certain shortcomings: although it can achieve the cleaning of the inside of the tank by setting a scraper, it only has two cross bars, and the setting of the scraper also makes the speed of the cross bar not too high, otherwise the life of the scraper is too low, resulting in low mixing efficiency, and the scraper needs to be replaced frequently. At the same time, the second drive motor is sealed through the chassis, which will cause poor heat dissipation of the second drive motor;

[0006] Accordingly, the utility model proposes a mixing device for pre-packaged food processing to solve the above problems. Utility Model Content

[0007] In order to overcome the defects in the above-mentioned prior art, the utility model provides a mixing device for pre-packaged food processing, which realizes the speed difference between the first stirring rod and the second stirring rod by setting the main gear and the secondary gear, thereby ensuring the stirring efficiency through the high-speed rotation of the first stirring rod, and at the same time can also improve the service life of the scraper as much as possible while cleaning the side wall through the low speed of the second rotating shaft and the scraper.

[0029] Furthermore, the power mechanism 901 includes a main gear 25 fixed on the second rotating shaft 9, the outer side of the main gear 25 is meshedly connected with three secondary gears 10 fixed on the third rotating shaft 7, the upper side of the secondary gear 10 is provided with an inner cover 6 fixed on the tank cover 26, the inner cover 6 is fixed with a second motor 8 connected to the second rotating shaft 9 by power, and the upper side of the second motor 8 is provided with an outer cover 5 fixed on the tank cover 26.

[0030] Furthermore, heat dissipation holes (not shown) are provided on the outer cover 5 and the inner cover 6 .

[0031] Furthermore, the cleaning mechanism 902 includes a connecting rod 17 fixed to the lower end of the second rotating shaft 9, a connecting plate 20 is provided on the lower side of the connecting rod 17, an inner groove 21 is provided in the upper surface of the connecting plate 20, and a connecting groove 18 adapted to the connecting rod 17 is provided in the lower surface of the inner groove 21.

[0032] Furthermore, two scrapers 15 abutting against the inner wall of the tank body 2 are fixedly connected to both sides of the connecting plate 20 .

[0033] Furthermore, two limiting plates 16 are rotatably disposed in the inner groove 21 for limiting and fixing the connecting rod 17 and the connecting groove 18 .

[0034] Furthermore, an outlet portion 19 is provided at the lower end of the tank body 2 .

[0035] Furthermore, a plurality of positioning holes 4 in a circular array are provided in the upper end surface of the tank body 2 , and positioning rods 11 corresponding to the positioning holes 4 are fixedly provided on the lower surface of the tank cover 26 .

[0036] Furthermore, a first mounting plate 24 is disposed on the front side of the tank body 2 , a second mounting plate 22 is disposed on the front side of the tank cover 26 , and an electric telescopic rod 23 is fixedly connected between the second mounting plate 22 and the first mounting plate 24 .

[0037] Specifically, when in use, the electric telescopic rod 23 is started, thereby driving the tank cover 26 to move up and down, so as to realize the opening and closing of the tank cover 26. When the tank cover 26 is closed, the positioning rod 11 is inserted into the positioning hole 4, so as to realize the limiting and positioning of the tank cover 26;

[0038] After the material is added to the tank body 2, the tank cover 26 is closed, and the second motor 8 is started, so that the main gear 25 rotates and drives the secondary gear 10 to rotate. Since the main gear 25 is larger and has more teeth, the speed of the secondary gear 10 is greater than the speed of the main gear 25, that is, the speed of the first stirring rod 13 is greater than the speed of the scraper 15;

[0039] Thus, the first stirring rod 13 realizes the main stirring function, the second stirring rod 14 realizes the auxiliary stirring, and the scraper 15 realizes the side wall cleaning;

[0041] When installing the scraper 15, put the connecting rod 17 into the connecting groove 18, and then rotate the limit plate 16 to press and lock the connecting rod 17 to install the scraper 15 on the second rotating shaft 9. The existence of the inner groove 21 can prevent the internal material from driving the limit plate 16 to rotate.
