Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, and in particular to a premixing device for producing plastic color masterbatch. Background Technology

[0002] Color masterbatch, also known as colorant or color masterbatch, is a colorant specifically designed for new polymer materials. It mainly consists of dyes, carriers, and additives, and its coloring power is higher than that of the dye itself, thus it is widely used in the plastic coloring field. In the production process of color masterbatch, the carrier and additives need to be weighed and proportioned first, and then thoroughly mixed. The existing mixing method involves directly pouring the weighed and proportioned raw materials into a mixing device. Because all the raw materials accumulate together during the mixing process, the mixing speed is slow or the mixing is insufficient. Therefore, to solve the above problems, a pre-mixing device for plastic color masterbatch production has been designed. Utility Model Content

[0003] In view of the shortcomings of existing color masterbatch production technology, the purpose of this utility model is to provide a premixing device for plastic color masterbatch production, which has the advantages of preventing raw materials from piling up and ensuring thorough mixing.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a premixing device for producing plastic masterbatch, comprising a dispensing tank, a mixing tank, a discharge tray, a discharge assembly, a mixing hood, a diffuser plate, a drive shaft, and a mixing motor. The dispensing tank and the mixing motor are located at the top of the mixing tank, and the bottom of the mixing tank has a discharge port. The motor output shaft and the drive shaft are fixedly connected. The drive shaft extends into the interior of the mixing tank. The bottom of the drive shaft is provided with multiple diffuser plates arranged at equal angles, and the top of the drive shaft is provided with a mixing hood. The dispensing tank has multiple storage slots distributed at equal angles inside, and the bottom of the storage slots is connected to the top surface of the mixing tank. The discharge tray is rotatably connected between the dispensing tank and the mixing tank. The discharge assembly is located on the outer wall of the mixing tank to drive the discharge tray, and the discharge tray is used to connect or block the storage slots and the mixing tank.

[0005] Preferably, the number of storage slots is n, where n≥2;

[0006] Preferably, the mixing hood has a V-shaped cross-section, the outer diameter of the mixing hood is larger than the distribution distance of the storage tanks, and the top surface of the mixing hood also has multiple spraying ribs arranged at equal angles.

[0007] Preferably, the end face of the discharge tray has a plurality of discharge holes corresponding to the storage slots, and the outer edge of the discharge tray also has a toothed ring;

[0008] Preferably, the material feeding assembly has an opening and closing motor and a gear. The opening and closing motor is disposed on the outer wall of the mixing barrel. The output shaft of the opening and closing motor is fixedly connected to the gear. The gear extends into the mixing barrel and meshes with the outer edge gear ring of the material feeding disc.

[0009] Preferably, the bottom of the mixing tank also has supporting legs;

[0010] The beneficial effects of this utility model are: 1. By separating and storing the mixed materials in the mixing bucket, the materials will not accumulate and affect the mixing effect during the preparation stage of the mixed materials; 2. By setting a mixing cover and a diffusion plate in the mixing bucket, the mixing cover will evenly sprinkle the materials into the mixing bucket, and the diffusion plate will further diffuse and mix the materials, thereby achieving the effect of fully mixing the materials for the production of color masterbatch.

[0018] Please see Figures 1 to 4 The embodiments of this utility model include:

[0019] A premixing device for producing plastic masterbatch includes a dispensing tank 1, a mixing tank 2, a discharge tray 3, a discharge assembly 4, a mixing cover 5, a diffuser plate 6, a drive shaft 7, and a mixing motor 8. The dispensing tank 1 and the mixing motor 8 are located on the top of the mixing tank 2. The bottom of the mixing tank 2 has a discharge port 21. The motor output shaft and the drive shaft 7 are fixedly connected. The drive shaft 7 extends into the interior of the mixing tank 2. The bottom of the drive shaft 7 is provided with multiple diffuser plates 6 arranged at equal angles. The top of the drive shaft 7 is provided with a mixing cover 5. The dispensing tank 1 has multiple storage slots 11 distributed at equal angles. The bottom end of the storage slots 11 is connected to the top surface of the mixing tank 2. The discharge tray 3 is rotatably connected between the dispensing tank 1 and the mixing tank 2. The discharge assembly 4 is located on the outer wall of the mixing tank 2 to drive the discharge tray 3. The discharge tray 3 is used to connect or block the storage slots 11 and the mixing tank 2.

[0020] The number of storage slots 11 is n, where n≥2;

[0021] The mixing cover 5 has a V-shaped cross-section, and its outer diameter is larger than the distribution distance of the storage tank 11. The top surface of the mixing cover 5 also has multiple spraying ribs 51 arranged at equal angles.

[0022] The end face of the discharge tray 3 has a plurality of discharge holes 31 corresponding to the storage slots 11, and the outer edge of the discharge tray 3 also has a toothed ring 32.

[0023] The material feeding assembly 4 has an opening and closing motor 41 and a gear 42. The opening and closing motor 41 is installed on the outer wall of the mixing barrel 2. The output shaft of the opening and closing motor 41 is fixedly connected to the gear 42. The gear 42 extends into the mixing barrel 2 and meshes with the outer edge gear ring 32 of the material feeding disc 3.

[0024] The bottom of the mixing tank 2 also has supporting legs 9;

[0025] With the above settings, its specific working principle in actual operation is as follows:

[0026] During the feeding process, ensure that the discharge hole 31 on the end face of the discharge tray 3 is staggered from the opening of the storage tank 11. In this state, the storage tank 11 and the mixing tank 2 are blocked. Then, pour the prepared carrier and additive into the storage tank 11 in the dispensing cylinder to complete the feeding.

[0027] When mixing materials, the mixing motor 8 is started first. The mixing motor 8 drives the mixing hood 5 and the diffuser plate 6 located on the drive shaft 7 to rotate. Then the opening and closing motor 41 is started to drive the material drop plate 3 to rotate until the storage tank 11 and the mixing tank 2 are connected and then stop. During this process, the materials in multiple storage tanks 11 fall onto the mixing hood 5. Since the cross-sectional shape of the mixing hood 5 is V-shaped, the materials falling onto the mixing hood 5 will not slide directly, but will be evenly sprayed into the mixing tank 2 by the spraying rib 51. At the same time, the rotating diffuser plate 6 drives the materials in the mixing tank 2 to be in a spiral state, thereby further mixing the materials until the materials fall from the discharge port 21 at the bottom of the mixing tank 2, thus completing the premixing of the materials for color masterbatch production.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
