Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a mixing and feeding device for plastic product particle batching. Background Art

[0002] Plastic particles are plastic granules. Their upstream raw materials are petroleum. They mainly exist in the form of semi-finished plastics, which are convenient for people to store, transport and process. Plastic particles can be divided into thermoplastic plastic particles and thermosetting plastic particles according to their thermal changes. Thermoplastic plastics still have plasticity after repeated heating and cooling, but thermosetting plastic particles lose their plasticity once they are heated, cooled and solidified. The commonly used plastic particles in life are thermoplastic plastic particles, such as polyethylene, polypropylene, polyvinyl chloride, etc.

[0003] Before preparing plastic products, multiple plastic raw materials need to be mixed. A mixer is used in the mixing process. However, the existing mixers have the following problems during use:

[0004] First, the conventional mixing method is to put all the raw materials to be mixed into the mixing machine together. Due to the stratification phenomenon between different raw materials, it is difficult for the mixer to mix the raw materials above and below together during the mixing process. The mixing time is long and the mixing uniformity effect needs to be improved.

[0005] In addition, after the mixer finishes unloading, it is difficult to clean due to the closed internal space. If the residue is not cleaned in time, it will easily affect the quality of the next batch of raw materials, thereby reducing the quality of plastic products. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a mixing and feeding device for plastic product granule batching, which overcomes the deficiencies of the prior art and effectively solves the problems of long mixing time and great difficulty in cleaning.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A mixing and feeding device for plastic product granule batching, comprising a mixing barrel, a feeding frame is arranged on the outer wall of the bottom of the mixing barrel, a fixed pipe is welded to the inner wall of the feeding frame, a conveying auger is arranged on the inner wall of the fixed pipe, a butt pipe is welded to the outer wall of the top of the conveying auger, a first gear is fixedly connected to the top of the outer wall of the butt pipe, a second gear is meshed with the outer wall of the first gear, and a servo motor is fixedly connected to the outer wall of the second gear;

[0009] The outer wall of one end of the butt-joint pipe is fixedly connected with a water tank, and a sleeve is welded to the outer wall of the water tank. The inner wall of the sleeve is connected with a spring, and the outer wall of one end of the spring is connected with a telescopic column, and the outer wall of one end of the telescopic column is welded with a stirring rod.

[0010] Preferably, the water tank is rotatably connected to the inner wall of the fixed pipe.

[0011] Preferably, a mounting bracket is welded to the top outer wall of the mixing barrel, and the servo motor is fixedly connected to the top outer wall of the mounting bracket.

Under the rotation of the conveying auger 4, the raw materials will be forced to be transported to the top of the mixing barrel 1 and thrown out. With the cooperation of the first gear 6 and the second gear 7, the servo motor 8 can simultaneously drive the conveying auger 4 and the stirring rod 13 to rotate together, which greatly improves the efficiency of raw material stirring and improves the uniformity of raw material stirring.

[0027] In this embodiment, under the action of the water pump 15, high-pressure water can be transported from the water pipe 16 to the water tank 9 along the docking pipe 5. Under the impact of water, the spring 11 is expanded and the telescopic column 12 is away from the sleeve 10. At this time, the water flow can not only wash the inner wall of the cylinder, but also the stirring rod 13 can cling to the inner wall of the mixing cylinder 1 to scrape off the residue, which greatly reduces the difficulty of cleaning the inner wall of the mixing cylinder 1 and ensures the quality of each batch of plastic products after molding.

Under the rotation of the conveying auger 4, the raw materials will be forced to be transported to the top of the mixing barrel 1 and thrown out, and then stirred evenly by the stirring rod 13. During the stirring process, the material taking pipe 19 can be opened to observe the mixing situation. After the stirring is completed, the raw materials are discharged through the discharge pipe 18;

[0035] Afterwards, high-pressure water is transported from the water pipe 16 to the water tank 9 along the docking pipe 5 through the water pump 15. Under the impact of water, the spring 11 is expanded and the telescopic column 12 is away from the sleeve 10. At this time, the water flows along the sleeve 10 to wash the inner wall of the mixing barrel 1. At the same time, the stirring rod 13 can cling to the inner wall of the mixing barrel 1 to scrape off the residue, and the sewage is discharged from the discharge pipe 18.
