Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical mixing equipment, specifically relating to a two-dimensional motion mixer for solid dosage forms. Background Technology

[0002] Two-dimensional mixers are commonly used for mixing solid dosage forms. The full name is two-dimensional motion mixer. As the name suggests, it is a mixer in which the drum can move in two directions simultaneously. The two directions of movement are the rotation of the drum and the swing of the swing frame. The materials to be mixed are mixed by rotating, turning and tumbling in the drum, and at the same time, they are mixed by swinging back and forth with the swing frame. Under the combined action of these two movements, the materials are fully mixed in a short time.

[0003] Existing two-dimensional motion mixers for solid dosage forms still have some drawbacks. Most two-dimensional motion mixers have a single spiral surface inside the cylinder, which can only provide a single stirring effect, reducing the mixing efficiency and making it inconvenient to feed materials. Therefore, we propose a two-dimensional motion mixer for solid dosage forms. Utility Model Content

[0004] The purpose of this invention is to provide a two-dimensional motion mixer for solid dosage forms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a two-dimensional motion mixer for solid dosage forms, comprising a square frame base, with fixed frames symmetrically fixedly installed on the center of the surface of the square frame base, a U-shaped frame rotatably connected between the fixed frames, a fixed sleeve fixedly installed above the U-shaped frame, a stirring cylinder rotatably connected to the inner side of the fixed sleeve, an external gear fixedly sleeved on the center of the outer surface of the stirring cylinder, a first forward and reverse motor fixedly installed on one side of the top of the U-shaped frame, a main gear fixedly connected to the output end of the first forward and reverse motor, the main gear and the external gear being meshed, a worm gear rotatably connected laterally to the inner side of the square frame base, a second forward and reverse motor fixedly installed at the outer end of the square frame base, the output end of the second forward and reverse motor being fixedly connected to one end of the worm gear, and a semi-arc worm wheel fixedly installed at the bottom of the U-shaped frame, the worm gear and the semi-arc worm wheel being meshed.

[0006] Preferably, the mixing drum is provided with multiple sets of stirring rods inside, and one end of each stirring rod is fixedly connected to one end of the inner side of the mixing drum.

[0007] Preferably, a feed inlet is fixedly connected to one end of the outer side of the mixing drum, and a sealing cap is connected to the end of the feed inlet.

[0008] Preferably, a discharge port is fixedly connected to one end of the outer side of the mixing drum, and a switch valve is installed on one side of the surface of the discharge port.

[0009] Preferably, the fixing sleeve is symmetrically arranged on the outer sides of both ends of the mixing cylinder.

[0010] Preferably, the outer surface of the stirring cylinder is rotatably limited within the fixed sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By rotating the drum axially and oscillating it left and right, the raw materials inside the drum are mixed in multiple directions, thereby improving the uniformity of the mixture.

[0013] 2. By operating the second forward and reverse motor, the mixing drum is tilted to the right at a certain angle. Then, the valve is opened to pour out the raw materials inside the mixing drum, thus improving work efficiency. Attached Figure Description
