Description

Technical Field

[0001] This utility model relates to the technical field of plastic coloring devices, and in particular to a plastic raw material mixing and coloring device. Background Technology

[0002] As a widely used material, plastic is often colored, which plays a crucial role in both beautifying the appearance of products and improving their performance.

[0003] There are various methods for coloring plastics, commonly divided into two main categories: internal coloring (overall coloring) and surface coloring (post-processing coloring). Internal coloring includes masterbatch coloring, dry powder coloring, and liquid pigment coloring. In the process of overall plastic coloring, stirring is a key step to ensure uniform color distribution. Thorough stirring allows the pigment and plastic raw material to mix evenly, breaking up particle agglomerates, accelerating the full contact between the two, and thus improving coloring efficiency.

[0004] A search revealed that Chinese utility model patent CN221365310U discloses a plastic raw material mixer, including a mixing tank, a cover fixedly installed at the upper end of the mixing tank, a storage tank fixedly installed on the upper surface of the cover, and the lower end of the storage tank connected to the interior of the storage tank via a conveying pipe; a drive gear and multiple transmission gears are rotatably connected to the inner wall of the cover, with the multiple transmission gears meshing with the drive gear; and a stirring shaft and multiple turbulence shafts are fixedly connected to the shafts of the drive gear and the multiple transmission gears, respectively. This application uses a planetary gear system to simultaneously drive multiple turbulence shafts to rotate, thereby achieving the mixing of plastic raw materials with other materials. However, in this stirring mode, the shear force on the material is concentrated near the turbulence shafts. For plastic raw materials with high viscosity, this can easily create a stirring dead zone, causing the material to stagnate. Therefore, the stirring effect of this device is limited, making it difficult to guarantee the efficiency of coloring the plastic raw materials. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a plastic raw material mixing and coloring device, the main technical problem to be solved is how to ensure the efficiency of mixing and coloring plastic raw materials.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A plastic raw material mixing and coloring device includes a mixing tank, which is equipped with a circulating agitation mechanism and a driving mechanism. The circulating agitation mechanism includes a material cylinder and several propellers arranged on the same axis as the material cylinder. The driving mechanism drives the propellers to rotate to agitate the material and push the material to generate liquid flow. The inner wall of the material cylinder is provided with several rifling grooves to make the liquid flow rotate. Several support rods are provided between the material cylinder and the mixing tank to shear the liquid flow.

[0008] Furthermore, the top of the mixing tank is provided with a lid, which is adapted to the mixing tank. The drive mechanism includes a motor and a drive shaft, with the drive shaft passing through the lid.

[0009] Furthermore, the top of the bucket lid is fixedly connected to the outer part of the top of the drive shaft, the motor is fixedly connected inside the housing, and the bottom of the motor's output shaft is fixedly connected to the drive shaft.

[0010] Furthermore, the material cylinder is located in the middle of the mixing tank, the drive shaft passes through the material cylinder, and there are two propellers, which are located at the top and bottom of the inner side of the material cylinder, respectively.

[0011] Furthermore, both propellers are connected to the outside of the drive shaft by a key, and a base is fixedly connected to the middle of the bottom inner wall of the mixing tank, with the bottom end of the drive shaft extending into the interior of the base.

[0012] Furthermore, several support rods are equidistantly distributed outside the material cylinder, with both ends of the support rods fixedly connected to the mixing tank and the material cylinder, respectively.

[0013] Furthermore, the cross-section of the support rod is teardrop-shaped, and the support rod includes a gentle slope at the upper end and a steep slope at the lower end. The angle between the gentle slope and the Z-axis is smaller than the angle between the steep slope and the Z-axis.

[0014] Furthermore, the mixing tank is equipped with a heating element inside to keep the plastic raw material in a liquid state.

[0015] Furthermore, several support rods are equidistantly distributed at the top and bottom of the outer side of the material cylinder, with the support rods at the top and bottom of the outer side of the material cylinder being staggered.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This application utilizes a propeller, which can push the material to generate vertical flow while stirring it, so as to promote the material to circulate inside and outside the barrel. When the material flows through the inner wall of the barrel, it will also generate swirling flow under the action of the rifling, thereby improving the overall fluidity of the material and avoiding the formation of stirring dead zones. In addition, during the material circulation process, the support rod can provide additional shearing action for the material, thus achieving efficient mixing of raw materials and pigments, thereby ensuring the coloring efficiency of plastic raw materials.

[0018] 2. By setting up support rods, the gentle slope at the upper end can reduce the resistance during material flow and ensure the shearing effect on the material, while the steep slope at the lower end can form two vortices in opposite directions at the tail, thus further promoting material mixing.

[0019] 3. By setting up a split mixing tank and lid, after the raw materials are colored, the propeller can be taken out by removing the lid. At this time, the internal space of the mixing tank can be more spacious, thus making it easier to remove the materials.

[0020] 4. By setting several support rods at both the top and bottom of the outer side of the barrel, not only can the stability of the barrel be enhanced, but the different support rods set up in an alternating manner can also provide a double shearing action for the circulating material, thereby enhancing the mixing effect between the raw material and the pigment, and further improving the coloring efficiency of the raw material.

[0027] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0028] Example 1

[0029] See attached document Figure 1-3This application provides a plastic raw material mixing and coloring device, including a mixing tank 1. The mixing tank 1 is provided with a circulating stirring mechanism and a driving mechanism. The circulating stirring mechanism includes a material cylinder 3 and a plurality of propellers 9 arranged on the same axis as the material cylinder 3. The driving mechanism drives the propellers 9 to rotate to stir the material and push the material to generate liquid flow. The inner wall of the material cylinder 3 is provided with a plurality of rifling grooves 301 for generating rotation of the liquid flow. A plurality of support rods 2 for shearing the liquid flow are provided between the material cylinder 3 and the mixing tank 1.

[0030] Preferably, the top of the mixing tank 1 is provided with a tank cover 5, which is adapted to the mixing tank 1. The driving mechanism includes a motor 7 and a drive shaft 4, which is disposed through the tank cover 5.

[0031] When using this application, first put the lid 5 on the mixing tank 1, so that the drive shaft 4 passes through the material cylinder 3 and extends to the base 8. Then, the plastic raw materials and pigments can be put into the mixing tank 1 from the feed port on the lid 5, and then the motor 7 can be started.

[0032] Preferably, the top of the lid 5 is fixedly connected to the housing 6 outside the top of the drive shaft 4, the motor 7 is fixedly connected inside the housing 6, and the bottom of the output shaft of the motor 7 is fixedly connected to the drive shaft 4.

[0033] Preferably, the material cylinder 3 is located in the middle of the mixing tank 1, the drive shaft 4 passes through the material cylinder 3, and there are two propellers 9, which are located at the top and bottom of the inner side of the material cylinder 3, respectively. Both propellers 9 are connected to the outside of the drive shaft 4 by keys. A base 8 is fixedly connected to the middle of the inner wall of the bottom end of the mixing tank 1, and the bottom end of the drive shaft 4 extends into the interior of the base 8.

[0034] The motor 7 drives the drive shaft 4 to rotate, which enables the two propellers 9 to rotate at the top and bottom of the barrel 3 respectively. Thus, the propellers 9 can stir the material and push it to generate a vertical upward flow. If this continues, the material can circulate inside and outside the barrel 3. At the same time, the stirring action of the propellers 9 can promote the mixing of raw materials and pigments, thereby accelerating the coloring of plastic raw materials.

[0035] Preferably, several support rods 2 are equidistantly distributed on the outside of the material cylinder 3, and the two ends of the support rods 2 are fixedly connected to the mixing tank 1 and the material cylinder 3 respectively.

[0036] When the material flows from bottom to top in the barrel 3, the rifling on the inner wall of the barrel 3 can cause the liquid flow to swirl, thus promoting the dispersion of the material and improving the mixing effect. At the same time, when the material flows from top to bottom outside the barrel 3, the support rod 2 used to support the barrel 3 can also provide a shearing action, thus further ensuring the mixing of the material and ensuring the efficiency of raw material coloring.

[0037] Preferably, the cross-section of the support rod 2 is teardrop-shaped, and the support rod 2 includes a gentle slope portion 201 at the upper end and a steep slope portion 202 at the lower end. The angle between the gentle slope portion 201 and the Z-axis is smaller than the angle between the steep slope portion 202 and the Z-axis.

[0038] When the material flows through the support rod 2, the gentle slope at the upper end of the support rod 2 can reduce the resistance to the liquid flow and ensure the shearing effect on the material, while the steep slope at the lower end of the support rod 2 can generate two vortices in opposite directions at the tail end, thereby enhancing the mixing effect on the material.

[0039] After the plastic raw material is colored, the lid 5 can be removed from the mixing tank 1 after the motor 7 is turned off, so that the drive shaft 4 and propeller 9 can be taken out together. In this case, the internal space of the mixing tank 1 will be more spacious, so there will be less obstruction when taking out the material, thus making it easier to take out the material.

[0040] Preferably, the mixing tank 1 is equipped with a heating element inside to keep the plastic raw material in a liquid state.

[0041] Example 2

[0042] See attached document Figure 4 This application provides a plastic raw material mixing and coloring device. Compared with embodiment 1, in order to enhance the shearing effect of the support rod 2 on the material, several support rods 2 are equally distributed at the top and bottom of the outer side of the material cylinder 3, and the support rods 2 at the top and bottom of the outer side of the material cylinder 3 are staggered.

[0043] When the material flows from top to bottom outside the material cylinder 3, the support rods 2 located at the top and bottom of the outer side of the material cylinder 3 can provide a shearing effect. Since the two are arranged alternately, they can provide a double shearing effect for the material to ensure that the material is mixed evenly and colored uniformly.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
