Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring equipment technology, specifically a mixing and stirring device for preparing environmentally friendly packaging materials. Background Technology

[0002] In the preparation of environmentally friendly packaging materials, mixing is one of the key processes. Traditional mixing devices usually use a single rotary stirring method, with the stirring blades only revolving around a central axis. This results in insufficient uniformity of material mixing, especially for high-viscosity or multi-component materials, which can easily lead to localized incomplete mixing. Utility Model Content

[0003] The purpose of this invention is to provide a mixing and stirring device for preparing environmentally friendly packaging materials, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for preparing environmentally friendly packaging materials, comprising a mixing tank, a lid covering the top opening of the mixing tank, a servo motor mounted on the top of the lid via a fixed frame, the output end of the servo motor movably passing through the lid and connected to a drive shaft via a coupling, a drive groove being formed at the bottom of the drive shaft, and several connecting shafts being rotatably inserted at equal intervals on the outer wall of the drive shaft, a stirring fan blade being connected to the end of the connecting shaft, and the other end of the connecting shaft extending into the drive groove and fixed with a first bevel gear;

[0005] A fixed shaft is fixed at the bottom of the mixing tank. A second bevel gear is fixedly sleeved on the shaft wall inside the drive groove. The second bevel gear meshes with the first bevel gear.

[0006] Preferably, the top of the tank lid and the outer wall of the mixing tank are respectively fixedly connected to an inlet pipe and an outlet pipe.

[0007] Preferably, a sealing sleeve is fixedly sleeved on the shaft wall at the bottom of the drive shaft, and the sealing sleeve is rotatably inserted into the bottom wall of the mixing tank.

[0008] Preferably, the can lid is threaded onto the top of the mixing tank.

[0009] Preferably, the servo motor is electrically connected to an external power supply via a PLC controller.

[0010] Compared with existing technologies, the advantages of this invention are: the drive shaft is rotated by a servo motor, causing the stirring blades at the end of the connecting shaft to revolve; simultaneously, due to the meshing of the first bevel gear and the second bevel gear on the fixed shaft, the connecting shaft rotates synchronously during its revolution, forming a composite stirring mode of "revolution + rotation". This design significantly enhances the turbulent motion of materials, effectively improving mixing uniformity and stirring efficiency, and is especially suitable for the preparation of high-viscosity or multi-component environmentally friendly packaging materials.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 The present invention provides the following technical solution: a mixing and stirring device for preparing environmentally friendly packaging materials, including a mixing tank 1, a tank cover 2 covering the top opening of the mixing tank 1, a servo motor 5 mounted on the top of the tank cover 2 via a fixed frame, the output end of the servo motor 5 moving through the tank cover 2 and connected to a drive shaft 6 via a coupling, a drive groove 7 being opened at the bottom of the drive shaft 6, a plurality of connecting shafts 8 being rotatably inserted at equal intervals on the outer wall of the drive shaft 6, a stirring fan blade 9 being connected to the end of the connecting shaft 8, and the other end of the connecting shaft 8 extending into the drive groove 7 and fixed with a first bevel gear 10; a fixed shaft 11 is fixed at the bottom of the mixing tank 1, and a second bevel gear 12 is fixedly sleeved on the shaft wall of the fixed shaft 11 located inside the drive groove 7, and the second bevel gear 12 meshes with the first bevel gear 10.

[0017] A feed pipe 4 and a discharge pipe 3 are fixedly connected to the top of the tank lid 2 and the outer wall of the mixing tank 1, respectively. The feed pipe 4 and discharge pipe 3, equipped with shut-off valves, enable material feeding and discharging, while the shut-off valves control the material flow. A sealing sleeve 13 is fixedly fitted onto the shaft wall at the bottom of the drive shaft 6. The sealing sleeve 13 is rotatably inserted into the inner bottom wall of the mixing tank 1, improving the sealing between the drive shaft 6 and the mixing tank 1. The tank lid 2 is threaded onto the top of the mixing tank 1 to prevent accidental opening. The servo motor 5 is electrically connected to an external power supply via a PLC controller. The TB6600 PLC controller effectively controls the speed and direction of the servo motor 5, ensuring the device can drive normally.

[0018] Specifically, when using this invention, the mixed fluid material is conveyed into the mixing tank 1 through the feed pipe 4. After the material is added, the servo motor 5 is started by the PLC controller. When the servo motor 5 starts, it drives the drive shaft 6 to rotate. When the drive shaft 6 rotates, it drives the connecting shaft 8 and the stirring blades 9 to rotate synchronously. When the stirring blades 9 rotate inside the mixing tank 1 with the drive shaft 6 as the axis, they can mix the material. The first bevel gear 10 at the end of the connecting shaft 8 will roll along the second bevel gear 12. Since the second bevel gear 12 is fixedly sleeved on the shaft wall of the fixed shaft 11, the second bevel gear 12 is relatively stationary, so the first bevel gear 10 will drive the stirring blades 9 to rotate on its own axis while revolving around the central axis, forming a "revolution + rotation" compound mixing mode. This design significantly enhances the turbulent motion of the material, effectively improves the mixing uniformity and stirring efficiency, and is especially suitable for the preparation of high-viscosity or multi-component environmentally friendly packaging materials.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
