Description

Technical Field

[0001] This utility model belongs to the field of pet food processing technology, specifically relating to a mixing device for pet food processing. Background Technology

[0002] Pet food can be categorized by its form into dry pet food, such as fish food, dog food, cat food, and pet snacks; and semi-dry pet food, such as pet porridge, canned pet food, and pet meat sauce. Mixing devices used in pet food processing are employed to stir and mix the raw materials for pet food processing.

[0003] Chinese Patent CN218459267U discloses a pet food ingredient mixing device, including a first mixing tank and a second mixing cylinder. The first mixing tank has an inlet and a outlet, and the second mixing cylinder has an inlet and an outlet, with the inlet connected to the outlet. The first mixing tank contains a stirring device and a discharge control device. A first mixing motor for driving the stirring device and a cylinder for driving the discharge control device are located at the top of the first mixing tank. The stirring device is used to stir and mix the materials inside the tank, and the discharge control device is used to open and close the outlet to prevent the materials from being insufficiently stirred. The mixture is discharged from the discharge port; the second mixing cylinder is horizontally connected to the bottom of the first mixing tank, and a spiral mixer is horizontally installed inside. The spiral mixer includes a spiral rod and blades. The spiral rod passes through one end of the second mixing cylinder and is driven by a second mixing motor. The spiral mixer has the function of conveying materials forward and mixing materials. When the spiral mixer stops running, the material cannot be discharged from the second mixing cylinder. Therefore, when the mixing process enters continuous operation, there is no need for a material discharge control device to ensure that the material is discharged at will. It is only necessary to control the running speed of the spiral mixer to achieve the purpose of continuous and uniform mixing.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: existing mixing devices use a single stirring method, operate along a single stirring direction when multiple raw materials are used, and have little relative movement between the multiple raw materials, resulting in insufficient mixing. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for pet food processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for pet food processing, comprising a mixing tank, a stirring assembly, and a driving assembly. The stirring assembly includes a main shaft, a turntable, a spiral stirring rod, a paddle stirring rod, a moving gear, and an internal gear ring. There are two main shafts, which are rotatably mounted on the inner top and bottom walls of the mixing tank, respectively. The turntable is fixedly mounted on the main shafts. The spiral stirring rod and the paddle stirring rod are rotatably mounted on both sides of the turntable. Moving gears are fixedly mounted at the ends of both the spiral stirring rod and the paddle stirring rod. Internal gear rings are fixedly mounted on the inner top and bottom walls of the mixing tank. The moving gear meshes with the inner wall of the internal gear ring. The driving assembly includes a motor, a drive shaft, a main gear, and a driven gear. The motor is fixedly mounted on the outer wall of the mixing tank. The drive shaft is fixedly mounted on the output end of the motor. The main gear is fixedly connected to the end of the drive shaft. The driven gear is fixedly mounted on the end of the main shaft and meshes with the main gear.

[0007] In a preferred embodiment, a feed pipe is fixedly connected to both sides of the top of the mixing tank, and a discharge pipe is fixedly connected to one side of the bottom of the mixing tank.

[0008] In a preferred embodiment, a viewing window is provided on one side of the mixing tank.

[0009] In a preferred embodiment, a sleeve is fixedly installed on the inner wall of the mixing tank, and the drive shaft, main gear and driven gear are located inside the sleeve.

[0010] In a preferred embodiment, the turntable slides in contact with the end face of the internal gear ring.

[0011] In a preferred embodiment, a plurality of ring-shaped support legs are fixedly connected to the edge of the bottom of the mixing tank.

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

[0013] This pet food processing mixing device, through the arrangement of the stirring component and the drive component, can start the motor to drive the drive shaft to rotate during mixing. The drive shaft drives the main gear to rotate, which in turn drives the driven gear to rotate. The driven gear drives the main shaft to rotate, which in turn drives the turntable to rotate. The turntable drives the spiral stirring rod and the paddle stirring rod to move around the main shaft in a circular motion. At the same time, the spiral stirring rod and the paddle stirring rod will carry the moving gear to roll along the internal gear ring, so that the moving gear drives the spiral stirring rod and the paddle stirring rod to rotate on their own. This achieves a variety of mixing methods, and the irregular movement of the raw materials increases the relative movement between various raw materials, thereby making the mixing more thorough.

[0014] This pet food processing mixing device, through the installation of sleeves, can protect the drive shaft, main gear, and driven gear. Attached Figure Description
