Description

Technical Field

[0001] The utility model relates to the field of mixers, and particularly relates to a two-dimensional mixer for preparing compound paracetamol and amantadine hydrochloride tablets. Background Art

[0002] The two-dimensional mixer, whose full name is two-dimensional motion mixer, can perform two-directional motions simultaneously, namely the rotation of the rotating cylinder and the swing of the rotating cylinder along with the swing frame. This mixing method helps the materials to be fully mixed in a short time. The use of a two-dimensional mixer in the preparation process of compound paracetamol and amantadine hydrochloride tablets mainly involves the step of mixing raw materials. In the preparation process of compound paracetamol and amantadine hydrochloride tablets, raw materials such as paracetamol, amantadine hydrochloride, chlorpheniramine maleate (chlorpheniramine), caffeine and excipients such as artificial bezoar need to be mixed evenly after being pulverized and sieved. At this time, a two-dimensional mixer can be used to mix various powder raw materials to ensure uniform distribution of each component. The two-dimensional mixer is composed of three major parts: a rotating cylinder, a swing frame and a frame. The rotating cylinder is installed on the swing frame, supported by four rollers and axially positioned by two retaining wheels. Among the four supporting rollers, two of the driving wheels are driven by a rotating power system to make the rotating cylinder rotate. The swing frame is driven by a set of crank rocker mechanism. The crank rocker mechanism is installed on the frame, and the swing frame is supported on the frame by a bearing assembly, so that the rotating cylinder rotates and participates in the swing at the same time, so that the materials in the cylinder can be fully mixed. However, due to the lack of an auxiliary mixing mechanism in the rotating cylinder, the speed of full mixing of the raw materials is slow, which will further make the preparation process of compound paracetamol and amantadine hydrochloride tablets long and the preparation efficiency low. Therefore, a two-dimensional mixer for preparing compound paracetamol and amantadine hydrochloride tablets is needed to solve the above problems. Summary of the Utility Model

[0003] The utility model provides a two-dimensional mixer for preparing compound paracetamol and amantadine hydrochloride tablets, which solves the problem that the rotating cylinder of the traditional two-dimensional mixer lacks an auxiliary mixing mechanism, resulting in a slow speed of full mixing of raw materials.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0005] A two-dimensional mixer for preparing compound paracetamol and amantadine tablets, comprising a mixing drum, wherein an installation bracket is fixedly installed inside the mixing drum. The installation bracket consists of a polygonal frame, connecting fixing rods, and limiting baffles. There are four connecting fixing rods, which are symmetrically and fixedly installed on the polygonal frame. There are several limiting baffles, and two of them are symmetrically and fixedly sleeved on the polygonal frame. Several auxiliary mixing components are rotatably installed on the polygonal frame, and the auxiliary mixing components are located between two symmetrically arranged limiting baffles. The auxiliary mixing component consists of an installation sleeve, resistance-reducing rollers, a first mixing plate, a connecting block, and a second mixing plate. There are several resistance-reducing rollers, and they are all rotatably installed inside the installation sleeve. The first mixing plate is fixedly installed on the outer wall of the installation sleeve. The second mixing plate is located on one side of the first mixing plate, and the connecting block connects the first mixing plate and the second mixing plate.

[0006] Preferably, the mixing drum is rotatably installed on a swing frame, and the swing frame is rotatably installed on a bottom frame.

[0007] Preferably, one end of the mixing drum is provided with a feed inlet, and the other end of the mixing drum is provided with a discharge outlet.

[0008] Preferably, the connecting fixing rods on the installation bracket are fixedly connected to the inner wall of the mixing drum.

[0009] Preferably, the installation sleeve on the auxiliary mixing component is rotatably installed on the polygonal frame, and the installation sleeve is located between two symmetrically arranged limiting baffles.

[0010] Preferably, several installation grooves are formed on the inner wall of the installation sleeve on the auxiliary mixing component.

[0011] Preferably, the resistance-reducing rollers are rotatably installed in the installation grooves, and the resistance-reducing rollers are simultaneously in contact with the polygonal frame.

[0012] Preferably, the connecting block is fixedly connected to both the first mixing plate and the second mixing plate.

[0013] The working principle and beneficial effects of the present utility model are as follows:

[0014] When in use, the mounting bracket and the auxiliary mixing component will rotate with the rotation of the mixing drum, so that the second mixing plate on the auxiliary mixing component can assist in stirring and mixing the raw materials in the mixing drum, and at the same time, the auxiliary mixing component will swing on the mounting bracket with the swing of the mixing drum, so that the first mixing plate on the auxiliary mixing component can further assist in stirring and mixing the raw materials in the mixing drum, thereby increasing the speed of full mixing of the raw materials, and ultimately increasing the efficiency of preparing compound acetaminophen tablets; when the auxiliary mixing component swings on the mounting bracket, the drag reducing roller will generate friction rotation with the mounting bracket, so that the existence of the drag reducing roller can reduce the resistance of the auxiliary mixing component to swing on the mounting bracket, thereby making the auxiliary mixing component have a larger swing amplitude, and ultimately making the auxiliary mixing component have a better use effect; when the auxiliary mixing mechanism composed of the mounting bracket and the auxiliary mixing component is in use, there is no need to set up a separate power component, thereby reducing the cost of use and being more conducive to popularization and use.

One end of the mixing drum 3 is provided with a feed inlet 6, and the other end of the mixing drum 3 is provided with a discharge outlet 7. During operation, the raw materials for preparing compound paracetamol and amantadine tablets can be put into the mixing drum 3 through the feed inlet 6. During operation, the transmission wheel in the swing frame 2 is driven by a rotational power system to make the mixing drum 3 rotate, and a set of crank-rocker mechanisms in the bottom frame 1 will drive the swing frame 2 to swing, so that the mixing drum 3 rotates and participates in swinging at the same time, thereby enabling the raw materials in the mixing drum 3 to be fully mixed. Finally, the mixed raw materials can be taken out from the discharge outlet 7.

[0024] Embodiment 2

[0025] Please refer to Figure 2 、 Figure 3 、 Figure 4 As shown in, based on the same concept as the above Embodiment 1, this embodiment also proposes an auxiliary mixing mechanism.

[0026] In this embodiment, it includes an installation bracket 4 and an auxiliary mixing assembly 5. An installation bracket 4 is fixedly installed inside the mixing drum 3. The installation bracket 4 is composed of a polygonal frame 8, connecting and fixing rods 9, and limiting baffles 10. There are four connecting and fixing rods 9, which are symmetrically and fixedly installed on the polygonal frame 8. There are several limiting baffles 10, and two of them are symmetrically and fixedly sleeved on the polygonal frame 8. Several auxiliary mixing assemblies 5 are rotatably installed on the polygonal frame 8, and the auxiliary mixing assemblies 5 are located between two symmetrically arranged limiting baffles 10. The auxiliary mixing assembly 5 is composed of an installation sleeve 11, drag reduction rollers 13, a first mixing plate 14, a connecting block 15, and a second mixing plate 16. There are several drag reduction rollers 13, and they are all rotatably installed inside the installation sleeve 11. The first mixing plate 14 is fixedly installed on the outer wall of the installation sleeve 11. The second mixing plate 16 is located on one side of the first mixing plate 14. The connecting block 15 connects the first mixing plate 14 and the second mixing plate 16. The connecting and fixing rods 9 on the installation bracket 4 are fixedly connected to the inner wall of the mixing drum 3. The installation sleeve 11 on the auxiliary mixing assembly 5 is rotatably installed on the polygonal frame 8, and the installation sleeve 11 is located between two symmetrically arranged limiting baffles 10. Several installation grooves 12 are formed on the inner wall of the installation sleeve 11 of the auxiliary mixing assembly 5. The drag reduction rollers 13 are rotatably installed in the installation grooves 12, and the drag reduction rollers 13 are in contact with the polygonal frame 8 at the same time. The connecting block 15 is fixedly connected to both the first mixing plate 14 and the second mixing plate 16. During the rotation and swinging of the mixing drum 3, the installation bracket 4 and the auxiliary mixing assembly 5 will rotate along with the rotation of the mixing drum 3. At this time, the second mixing plate 16 on the auxiliary mixing assembly 5 can assist in stirring and mixing the raw materials in the mixing drum 3. At the same time, the auxiliary mixing assembly 5 will swing on the polygonal frame 8 of the installation bracket 4 along with the swinging of the mixing drum 3 and the swinging frame 2. At this time, the first mixing plate 14 on the auxiliary mixing assembly 5 can further assist in stirring and mixing the raw materials in the mixing drum 3, thereby improving the speed of full mixing of the raw materials and ultimately improving the efficiency of preparing compound paracetamol and amantadine hydrochloride tablets. When the auxiliary mixing assembly 5 swings on the polygonal frame 8 of the installation bracket 4, the drag reduction rollers 13 will rotate due to friction with the polygonal frame 8. Therefore, the presence of the drag reduction rollers 13 can reduce the resistance of the auxiliary mixing assembly 5 when swinging on the polygonal frame 8, thereby enabling the auxiliary mixing assembly 5 to have a larger swinging amplitude and ultimately making the use effect of the auxiliary mixing assembly 5 better. When the auxiliary mixing mechanism composed of the installation bracket 4 and the auxiliary mixing assembly 5 is in use, there is no need to separately set up a power component, which can reduce the use cost and is more conducive to popularization and use.
