Description

Technical Field

[0001] The utility model relates to the technical field of color paste processing, in particular to a mixing device for color paste modulation. Background Art

[0002] Colorants for polymer materials such as plastics, rubber, and thermoplastic elastomers are indispensable substances in the modern polymer processing process. They can not only beautify the appearance of products, but also have some other functions, such as easy color identification, improved weather resistance and heat resistance of products, etc. Since carbon black not only has excellent coloring properties, but also has a reinforcing effect on rubber, carbon black has gradually become an indispensable raw material for the rubber industry. Generally, carbon black needs to be made into black paste and added to polymer materials such as plastics, rubber, or thermoplastic elastomers. In the production process, a color paste mixing device is required.

[0003] A Chinese patent with announcement number CN209934556U discloses a color paste mixing device, including a mixing tank body, wherein the upper and lower ends of the mixing tank body are respectively connected to a feed funnel and a discharge pipe sleeve, a stirring motor is also fixed on the mixing tank body, the output shaft of the stirring motor extends into the mixing tank body, a plurality of stirring paddles are also provided on the output shaft, two parallel first rollers and second rollers are also provided in the discharge pipe sleeve, a first rotating motor and a second rotating motor are fixed on the outside of the discharge pipe sleeve, the output end of the first rotating motor is fixedly connected to the first roller, and the output end of the second rotating motor is fixedly connected to the second roller.

[0004] Although the color paste mixing device described in the above patent can avoid the pollution of dust to the environment during feeding, and ensure the convenient crushing of large particles in the color paste after mixing, the large particles in the color paste are crushed during the discharge process after mixing. It is easy for the crushed large particles to fall with the color paste and cannot be effectively stirred and dispersed, which causes the crushed large particles to easily stick together in the color paste, and cannot fundamentally solve the problem of uneven mixing of large particles in the color paste.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] like Figure 1-Figure 3 As shown, a mixing device for color paste modulation in this embodiment includes a mixing tank 2, a feeding pipe 6 is welded at the feeding port at the upper end of the mixing tank 2, a vibrating screening mechanism 8 is installed in the middle of the feeding pipe 6, and the vibrating screening mechanism 8 includes a fixed plate 802 symmetrically installed on the inner wall of the feeding pipe 6, a spring rod 804 symmetrically installed on both sides of the upper end of each fixed plate 802, a screening mesh plate 801 installed on the top of the spring rod 804, a long strip hole 806 opened in the middle of the bottom end of the screening mesh plate 801, a vibration motor 805 installed between the two spring rods 804 on the same side of the screening mesh plate 801, and a vibration motor 805 installed on one side of each fixed plate 802. The elastic cloth 803 is used to block the material. After the vibration motor 805 is started, the spring rod 804 will be used to make the screening mesh plate 801 vibrate up and down to ensure that the fine components in the color paste raw material can smoothly enter the mixing tank 2, while the large particles in the raw material are intercepted by the screening mesh plate 801 and fall through the long holes 806. Two grinding rollers 9 are symmetrically installed below the long holes 806 in the feeding pipe 6. A grinding motor 5 is installed on the outer wall of the feeding pipe 6 opposite to each grinding roller 9. The grinding motor 5 drives the grinding roller 9 to rotate to crush the large and large particles in the material after screening to ensure the uniformity of the material when it is put in.

[0031] like Figure 1-Figure 3As shown, in this embodiment, the grinding motor 5 is bolted to the feeding pipe 6, the grinding roller 9 is rotatably connected to the feeding pipe 6, the grinding motor 5 is connected to the grinding roller 9 by a coupling, the fixed plate 802 is welded to the feeding pipe 6, the fixed part of the spring rod 804 is bolted to the fixed plate 802, the telescopic part of the spring rod 804 is bolted to the screening mesh plate 801, the screening mesh of the screening mesh plate 801 is smaller than the long hole 806, and the long hole 806 is located directly above the grinding gap between the two grinding rollers 9, which can ensure that the large particle material falling through the long hole 806 can be fully ground and crushed by the grinding roller 9.

[0032] like Figure 1-Figure 2 As shown, in this embodiment, a stirring mechanism 7 is further installed in the middle of the mixing tank 2. The stirring mechanism 7 includes a stirring motor 701 installed in the middle of the upper end of the mixing tank 2 by bolts and a mixing frame 702 installed at the power output end of the stirring motor 701. When the material is put into the mixing tank 2, the mixing frame 702 is driven to rotate under the action of the stirring motor 701 to achieve sufficient mixing of the material.

[0033] like Figure 1-Figure 2 As shown, in this embodiment, a dust suction mechanism 1 is further installed on one side wall of the mixing tank 2, and the dust suction mechanism 1 includes a dust suction box 102 fixed to the mixing tank 2 by bolts, a negative pressure pump 103 installed on one side wall of the dust suction box 102, and a dust hood 101 installed on the top of the feeding pipe 6.

A discharge pipe 4 with a valve is also installed in the middle of the bottom end of the mixing tank 2. The bottom end of the mixing tank 2 is located on the outside of the discharge pipe 4 and is welded with three legs 3 in a ring shape. After the mixed materials are stirred, the mixed materials can be fully discharged under the action of the discharge pipe 4.

[0034] The specific implementation process of this embodiment is as follows: when mixing, the raw materials in the color paste preparation are first put into the feeding pipe 6. After the raw materials enter the feeding pipe 6, they will first be preliminarily filtered and screened under the action of the vibration screening mechanism 8, so that fine materials can fall quickly, and the large particles of materials filtered and retained will be ground and crushed when passing through the grinding roller 9, and then enter the mixing tank 2. After the materials are added, it is only necessary to drive the mixing frame 702 to rotate under the action of the stirring motor 701, so that the color paste raw materials can be mixed while the mixing frame 702 rotates, and the mixed materials are finally discharged from the discharge pipe 4. In the above mixing process, not only the rapid falling of qualified powdered materials is achieved by vibration screening, but also the large particles of materials in the color paste preparation raw materials are crushed by grinding, which effectively ensures the uniformity of the color paste after final mixing, so that the quality of the color paste raw materials after mixing is better.
