Description

Technical Field

[0001] This utility model relates to meat processing machinery, specifically disclosing a heat dissipation mechanism for a motor of a meat grinder / shredder. Background Technology

[0002] There is an existing Chinese patent, patent number 201720991342.3, entitled "Meat Grinder and Meat Cutter Dual-Purpose Machine," which includes a geared motor and a gearbox. The geared motor is cooled by ventilation holes located at the bottom of the housing. This cooling method is not very effective, and poor cooling directly affects the lifespan of the motor. In addition, the motor housing is spliced ​​with gaps. Since meat grinders and meat cutters are often used in wet environments, water can easily enter through these gaps, causing damage to the motor. Summary of the Invention

[0003] The purpose of this invention is to provide a motor cooling mechanism for a meat grinder / cutter that can efficiently dissipate heat from the motor, in order to solve the above problems.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A cooling mechanism for a dual-purpose meat grinder includes a motor and a gearbox. A cooling fan is connected to the power output shaft of the motor. A protective cover is provided on the outside of the motor to enclose the motor and the cooling fan. The protective cover is connected to the gearbox. An air inlet is provided at the front end of the protective cover, and an air duct is provided on the inside. An air outlet is provided on the inside of the connection between the gearbox and the motor. An air outlet is provided on the back of the gearbox at the position corresponding to the air outlet.

[0006] Furthermore, the air duct is located inside the protective cover and outside the motor housing.

[0007] Furthermore, the upper part of the protective cover fits the shape of the motor, and air ducts are provided on the lower left and right sides; air inlets are provided on the side wall of the motor corresponding to the positions of the air ducts on the left and right sides of the protective cover.

[0008] Furthermore, an air inlet is provided at the front end of the motor; the air duct is located inside the motor housing.

[0009] Furthermore, the air inlet and / or air outlet are grille louvered air outlets.

[0010] Furthermore, support feet are provided below the protective cover.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This invention, by incorporating a cooling fan, a protective cover, and a clever airflow design, can efficiently dissipate heat from the motor. Simultaneously, the protective cover effectively prevents moisture from entering the motor through gaps in the motor wall, thus doubly ensuring the motor's lifespan. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, a cooling mechanism for a dual-purpose meat grinder includes a motor 1 and a gearbox 2. A cooling fan 3 is connected to the power output shaft of the motor 1 (one end of the power output shaft of the motor 1 is connected to the gearbox 2, and the other end is connected to the cooling fan 3). A protective cover 4 is provided on the outside of the motor 1 to enclose the motor 1 and the cooling fan 3. The protective cover 4 and the gearbox 2 are detachably connected by bolts for easy maintenance. An air inlet 5 is provided at the front end of the protective cover 4 (the air inlet 5 shown in the figure is a hollowed-out design of the company logo), and an air duct 6 is provided on the inner side. The air duct 6 is located inside the protective cover 4 and outside the motor 1 housing. Specifically, the upper part of the protective cover 4 fits the shape of the motor 1, and the lower left and right sides are provided with air ducts 6. Air inlets 7 are provided on the side wall of the motor 1 corresponding to the left and right air ducts 6 on the protective cover 4. An air outlet 8 is provided on the inner side of the connection between the gearbox 2 and the motor 1. An air outlet 9 is provided on the back of the gearbox corresponding to the air outlet 8.

[0020] like Figure 5 As shown, when the cooling fan 3 starts, cold air enters the protective cover 4 from the air inlet 5, passes through the air duct 6, and enters the motor 1 from the air inlet 7, directly cooling the core part of the motor 1. After heat exchange, the hot air exits from the air outlet 8 to the air outlet 9 for discharge.

[0021] The air inlet 5 and / or air outlet 9 are louvered grille vents, which can effectively prevent moisture from entering the machine.

[0022] Support feet are provided below the protective cover 4.

[0023] In another embodiment, not shown in the figure, an air inlet 7 is provided at the front end of the motor 1; the air duct 6 is provided inside the housing of the motor 1; as long as the housing of the motor 1 is appropriately thickened, the opening at the front end can serve as the air inlet 7.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
