Technical Field
[0001] The present application relates to the technical field of raw material mixing devices, and in particular to a raw material mixing device for producing plastic pipes. Background Art
[0002] Plastic pipe is a widely used pipe material with the advantages of light weight, corrosion resistance, easy processing and installation. The production steps of plastic pipe mainly include raw material selection, raw material mixing, extrusion molding, cooling and shaping, cutting, inspection and packaging.
[0003] After selecting the various raw materials required for the production of plastic pipes, the various raw materials need to be stirred and mixed, such as stabilizers, lubricants, plasticizers, colorants and fillers, which are evenly dispersed in the base resin, thereby reducing the situation where the local concentration is too high or too low, so that when the various raw materials are subsequently heated and melted, the various raw materials can react more fully, which helps to improve the plasticizing efficiency and product quality in the subsequent extrusion process. However, at present, the mixing equipment does not mix the raw materials of plastic pipes sufficiently, and it is difficult to mix the basic raw materials and auxiliary materials evenly, which affects the quality of the final plastic pipe.

The spiral blade stirs and mixes the raw materials in the mixing barrel. It is difficult for the spiral blade to stir the raw materials in the gap between the spiral blade and the stirring shaft. Under the action of the short stirring rod, the raw materials between the spiral blade and the stirring shaft can be stirred and mixed, so that the various raw materials are mixed more fully, thereby improving the uniformity of the mixing of the various raw materials, and then improving the plasticizing efficiency and product quality in the subsequent extrusion process.

[0009] By adopting the above technical solution, it is more difficult for the spiral blade to stir the gap between the spiral blade and the inner wall of the mixing barrel. Under the action of the long stirring rod, the raw materials between the spiral blade and the inner wall of the mixing barrel can be stirred and mixed, so that the various raw materials can be stirred and mixed more fully, thereby further improving the uniformity of the mixing of the various raw materials.
[0010] Preferably, there are multiple short stirring rods, and the multiple short stirring rods are distributed along the vertical direction of the stirring shaft, and the multiple short stirring rods have different directions.

[0015] By adopting the above technical solution, the directions of the multiple short stirring rods and the multiple long stirring rods are different, so that the stirred raw materials are made more disorderly, thereby further improving the uniformity of mixing the various raw materials.
[0016] Preferably, a guide plate group is fixed to the inner wall of the mixing barrel, and the guide plate group includes guide plates. The guide plates are arranged obliquely, and the inclination direction is downward from the inner wall of the mixing barrel to the center of the mixing barrel.
[0017] By adopting the above technical solution, when the raw materials fall into the gap between the long stirring rod and the inner wall of the mixing barrel during the stirring process, the raw materials can be guided into the stirrable range under the action of the guide plate, so that the raw materials in the mixing barrel can be fully stirred and mixed.
[0018] Preferably, there are multiple guide plate groups, and the multiple guide plate groups are distributed along the inner wall of the mixing barrel in the vertical direction.

[0020] Preferably, the mixing barrel is a funnel-shaped barrel.
[0021] By adopting the above technical solution, the mixing barrel is a funnel-shaped barrel, so that the raw materials in the mixing barrel can be better discharged from the bottom after mixing, reducing the situation of incomplete discharge of the raw materials when discharging.

The spiral blade stirs and mixes the raw materials in the mixing barrel. It is difficult for the spiral blade to stir the raw materials in the gap between the spiral blade and the stirring shaft. Under the action of the short stirring rod, the raw materials between the spiral blade and the stirring shaft can be stirred and mixed, so that the various raw materials are mixed more fully, thereby improving the uniformity of the mixing of the various raw materials, and then improving the plasticizing efficiency and product quality in the subsequent extrusion process.

[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] The embodiment of the present application discloses a raw material mixing device for producing plastic pipes.
[0030] Reference Figure 1A raw material mixing device for plastic pipe production includes a mixing barrel 1, which has a storage cavity inside. The raw materials are placed in the storage cavity. In the embodiment of the present application, the mixing barrel 1 is a funnel-shaped barrel, so that the raw materials in the mixing barrel 1 can be better discharged from the bottom after mixing. A feed port is opened through the top surface of the mixing barrel 1, and a feed hopper 11 is fixed on the top surface of the mixing barrel 1. The bottom of the feed hopper 11 is inserted into the feed port, and the raw materials enter the cavity of the mixing barrel 1 through the feed hopper 11.
[0031] Reference Figure 2 A driving member is installed on the top surface of the mixing barrel 1. In the embodiment of the present application, the driving member is a motor 2. A stirring shaft 3 is rotatably connected to the top of the mixing barrel 1. One end of the stirring shaft 3 passes through the top surface of the mixing barrel 1, and the protruding part of the stirring shaft 3 is assembled with the output end of the motor 2. The motor 2 is started, and the motor 2 drives the stirring shaft 3 to rotate. A spiral blade 4 is fixed to the outer wall of the stirring shaft 3. The top and bottom ends of the spiral blade 4 are respectively fixed at the two ends of the stirring shaft 3, and the spiral blade 4 surrounds the stirring shaft 3. The raw materials enter the cavity of the mixing barrel 1 from the feed hopper 11. The motor 2 is started, and the motor 2 drives the stirring shaft 3 to rotate, thereby driving the spiral blade 4 to rotate, and the spiral blade 4 stirs and mixes the raw materials in the mixing barrel 1.
[0032] A short stirring rod 5 is fixed to the outer wall of the stirring shaft 3. The short stirring rod 5 is horizontally arranged and is located in the gap between the spiral blade 4 and the stirring shaft 3. Start the motor 2 to make the short stirring rod 5 and the spiral blade 4 rotate simultaneously. It is difficult for the spiral blade 4 to stir the raw materials in the gap between the stirring shaft 3. Under the action of the short stirring rod 5, the raw materials between the spiral blade 4 and the stirring shaft 3 can be stirred and mixed, so that the various raw materials are mixed more fully, thereby improving the uniformity of the mixing of the various raw materials. There are multiple short stirring rods 5, and the multiple short stirring rods 5 are distributed along the vertical direction of the stirring shaft 3. The multiple short stirring rods 5 have different directions, so that the multiple short stirring rods 5 stir the raw materials more disorderly, thereby further improving the uniformity of the mixing of the various raw materials.
[0033] A long stirring rod 6 is fixed to the outer wall of the stirring shaft 3. The long stirring rod 6 is arranged horizontally.

Correspondingly, a gap is also arranged between the long stirring rod 6 and the inner wall of the mixing barrel 1 to reduce the friction between the long stirring rod 6 and the inner wall of the mixing barrel 1 when rotating. The gap between the long stirring rod 6 and the inner wall of the mixing barrel 1 is smaller than the gap between the spiral blades 4 and the inner wall of the mixing barrel 1, and it is difficult for the spiral blades 4 to stir into the gap between the inner wall of the mixing barrel 1. Under the action of the long stirring rod 6, the raw materials between the spiral blades 4 and the inner wall of the mixing barrel 1 can be stirred and mixed, so that a variety of raw materials can be stirred and mixed more fully, thereby further improving the uniformity of mixing of a variety of raw materials.

The long stirring rods 6 and the short stirring rods 5 are alternately arranged, and the directions of the multiple short stirring rods 5 and the multiple long stirring rods 6 are different, so that the multiple short stirring rods 5 and the multiple long stirring rods 6 can stir the raw materials in different parts, thereby making the raw materials mixed more evenly.
[0035] Reference Figure 2 A guide plate group 7 is fixed to the inner wall of the mixing barrel 1, and the guide plate group 7 includes a plurality of guide plates 71, and the plurality of guide plates 71 are distributed along the circumference of the inner wall of the mixing barrel 1, and the guide plates 71 are inclined, and the inclination direction is downward from the inner wall of the mixing barrel 1 to the center of the mixing barrel 1, and a gap is provided between the guide plate 71 and the spiral blade 4, so as to reduce the influence of the guide plate 71 on the rotation of the spiral blade 4, and there are a plurality of guide plate groups 7, and the plurality of guide plate groups 7 are distributed along the vertical direction of the inner wall of the mixing barrel 1.

When the raw materials fall into the gap between the long stirring rod 6 and the inner wall of the mixing barrel 1 during the stirring process, the guide plate 71 can guide the raw materials to fall into the stirrable range, so that the raw materials in the mixing barrel 1 can be fully stirred and mixed.
[0037] A material discharge port is provided through the bottom of the mixing barrel 1 , and a control valve 12 is installed on the bottom of the mixing barrel 1 . The opening of the control valve 12 is aligned with the material discharge port. When the control valve 12 is opened, the mixed raw materials can be discharged from the opening of the opened control valve 12 .
