Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a ribbon mixer with a large mixing range. Background Technology

[0002] Ribbon mixers, with their simple structure and high mixing efficiency, are widely used in the mixing of powder or granular materials in chemical, food, and building materials industries. Their core working principle involves a drive unit that rotates a ribbon around an axis, using the ribbon's helical surface to push the material, causing axial flow and radial diffusion within the drum, thus achieving mixing.

[0003] Currently, traditional ribbon mixers use a single ribbon structure, where the ribbon only rotates around its own axis (self-rotation). Its mixing trajectory is a concentric circle with a fixed radius. This movement mode results in a limited radial coverage range, making it difficult to meet the needs of large-scale, dead-angle-free mixing and inconvenient to use. Therefore, based on the above shortcomings, a ribbon mixer with a large mixing range is introduced to improve this. Utility Model Content

[0004] The purpose of this invention is to provide a ribbon mixer with a large mixing range to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ribbon mixer with a large mixing range, comprising a shell, brackets mounted on both the left and right sides of the bottom end of the shell, a discharge port provided at the bottom end of the shell, a first connecting seat and a second connecting seat rotatably connected to the left and right sides of the inner cavity of the shell respectively via bearings, the left side of the first connecting seat extending out of the left end face of the shell, two interconnected connecting rods provided on the inner sides of the first and second connecting seats, a protective plate provided on the left side of the shell, one end of a first drive shaft rotatably connected to the upper and lower ends of the left side of the inner cavity of the first connecting seat via bearings, the other end of the first drive shaft extending out of the first connecting seat and rotatably connected to the outer wall of the second connecting seat via bearings, the first drive shaft... A first gear is provided on the left side of the outer wall of the first drive shaft, and a secondary threaded ribbon is provided on the right side of the outer wall of the first drive shaft.

A main threaded ribbon is provided on the right side of the outer wall of the second drive shaft. A second gear, a limiting plate, and a fourth gear are installed on the left side of the outer wall of the second drive shaft. The fourth gear is meshed with the first gear. Teeth are provided on the circumference of the outer wall of the first connecting seat. A motor is screwed to the bottom left side of the housing. A third gear is installed on the output end of the upper surface of the motor. The third gear is meshed with the second gear and the teeth.

The protective plate 7 is not only used for the installation and connection of other structures, but also to shield the exposed transmission structure, thus playing a protective role. One end of a first drive shaft 8 is rotatably connected to the upper and lower ends of the left side of the inner cavity of the first connecting seat 4 via bearings. The other end of the first drive shaft 8 extends out of the first connecting seat 4 and is rotatably connected to the outer wall of the second connecting seat 5 via bearings. The left side of the outer wall of the first drive shaft 8 is provided with... The device includes a first gear 9 located inside the first connecting seat 4. A secondary threaded ribbon 10 is provided on the right side of the outer wall of the first drive shaft 8. One end of the second drive shaft 11 is rotatably connected to the center of the left side of the second connecting seat 5 via a bearing. The other end of the second drive shaft 11 passes through the outer wall of the first connecting seat 4 and the housing 1 and is rotatably connected to the right side of the protective plate 7 via a bearing. A main threaded ribbon 12 is provided on the right side of the outer wall of the second drive shaft 11. A second gear 13, a limiting plate 14, and a fourth gear 18 are installed on the left side of the outer wall of the second drive shaft 11. The fourth gear 18 is located inside the first connecting seat 4 and meshes with the first gear 9. Teeth 15 are provided on the circumference of the outer wall of the first connecting seat 4. A motor 16 is screwed to the bottom left side of the housing 1. A third gear 17 is installed on the output end of the upper surface of the motor 16. The third gear 17 meshes with the second gear 13 and the teeth 15.

[0018] As a preferred option, the protective plate 7 is further disposed on the outside of the third gear 17, the second gear 13 and the teeth 15.

[0019] All electrical components mentioned in this solution are existing technologies, and their models are only one of them. Any electrical component that meets the requirements of this solution can be used.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control. The specific work is as follows.

[0021] In use, pour the material into the housing 1 and turn on the motor 16. The motor 16 will drive the third gear 17 to rotate. Since the third gear 17 meshes with the second gear 13 and the teeth 15, when the third gear 17 rotates, it will push the teeth 15 to cause the first connecting seat 4 and all the structural components on the first connecting seat 4 to rotate together. That is, the auxiliary screw ribbon 10 and the main screw ribbon 12 will rotate and move around the second drive shaft 11. At the same time, the third gear 17 will push the second gear 13 to cause the second drive shaft 11 and all the structural components on the second drive shaft 11 to rotate together. Since the fourth gear 18 meshes with the first gear 9, when the second drive shaft 11... When rotating, the fourth gear 18 on its outer wall will drive the first gear 9 to rotate together with the first transmission shaft 8. That is, the auxiliary screw ribbon 10 on the first transmission shaft 8 and the main screw ribbon 12 on the second transmission shaft 11 will rotate simultaneously. At this time, the auxiliary screw ribbon 10 and the main screw ribbon 12 will revolve around the second transmission shaft 11 as the center while rotating on their own axis. This allows the material inside the shell 1 to be mixed and processed. The device adopts a linkage design of the revolution and rotation of two screw ribbons. Compared with the existing screw ribbon mixer, when the two screw ribbons revolve around the central axis, they can also rotate on their own axis, so as to cover the entire radial range from the center of the cylinder to the inner wall, significantly expanding the mixing range and improving the mixing effect. It is easy to use, highly practical, and suitable for promotion.
