Description

Technical Field

[0001] This utility model relates to the field of plastic processing and production technology, and in particular to a mixing and feeding device for plastic molds used in household appliances. Background Technology

[0002] Home appliance plastic parts refer to various plastic components used in home appliance products, such as refrigerator door shells, washing machine control panels, and air conditioner housings. These plastic parts are usually made of engineering plastics such as ABS, polycarbonate (PC), and polypropylene (PP). During processing, plastic granules are heated to a molten state and then injected into a pre-made mold under high pressure. After cooling and solidification in the mold, the desired shape of the plastic part is obtained. Since home appliance plastic parts are made of multiple materials, the materials need to be mixed before heating. However, current mixing devices mainly mix by stirring, but there may be large particles in the materials, and the mixing effect of materials by stirring alone is poor, resulting in product defects.

[0024] Reference Figure 1-3 This utility model provides a mixing and feeding device for plastic molds used in household appliances, comprising:

[0025] The feeding unit 100 includes a base 101, a housing 102 fixedly connected to the upper surface of the base 101, a crushing roller 103 rotatably connected to the upper part of the inner wall of the housing 102, a drive motor 104 fixedly connected to one end of the crushing roller 103, a mixing component 105 provided in the middle of the inner wall of the housing 102, a discharge funnel 107 fixedly connected to the lower end of the housing 102, a screw feeder 108 fixedly connected to the lower end of the discharge funnel 107, the lower surface of the screw feeder 108 fixedly connected to the inside of the base 101, and a second heater 109 fixedly connected to the outer surface of the screw feeder 108. The base 101 serves as the main support, ensuring the stability of the entire device and providing sufficient support for each component, ensuring the stability of the equipment during long-term use. The crushing roller 103, connected to the drive motor 104, provides continuous power, enabling the material to be effectively crushed before entering the mixing zone. It can crush larger plastic raw materials into smaller particles suitable for mixing. The efficient operation of the mixing component 105 ensures that different types or specifications of plastic materials are mixed evenly, avoiding material stratification or unevenness, thereby improving the quality and consistency of the finished mold products. The screw feeder 108, through its screw drive structure, effectively controls the conveying speed and direction of the material, preventing blockage or leakage during the conveying process and ensuring the efficient operation of the production line.

[0026] The mixing assembly 105 includes a mixing chamber 105a and a servo motor 105e. The outer surface of the mixing chamber 105a is fixedly connected to the inner wall of the housing 102. A spiral blade 105b is rotatably connected to the inner wall of the mixing chamber 105a. A stirring blade 105c is fixedly connected to the lower end of the spiral blade 105b, and a gear ring 105d is fixedly connected to the upper end of the stirring blade 105c. The servo motor 105e is fixedly connected to the outer surface of the housing 102, and a gear 105f is fixedly connected to the output end of the servo motor 105e. An opening is provided on one side of the housing 102, and the outer surface of the gear 105f meshes with the outer surface of the gear ring 105d through the opening. The outer surface of the gear ring 105d is rotatably connected inside the housing 102. A first heater 106 is fixedly connected to the middle of the outer surface of the mixing chamber 105a. The outer surface of the stirring blade 105c is disposed inside the discharge funnel 107. The mixing chamber 105a is disposed below the crushing roller shaft 103. The mixing chamber 105a, as the core container, employs a combination of spiral blades 105b and stirring blades 105c, which can create a strong material flow and stirring effect within the chamber 102. This multi-dimensional stirring method ensures sufficient contact and fusion of plastic raw materials with different particle sizes and compositions during the mixing process, thereby improving the material uniformity during mold forming. The servo motor 105e provides precise rotation control through precise control of the meshing of gears 105f and gear rings 105d, allowing adjustment of mixing speed and stirring intensity as needed to adapt to different types of materials. The first heater 106 is fixedly connected to the center of the outer surface of the mixing chamber 105a, which helps to uniformly heat the material during the mixing process, ensuring that the plastic particles have ideal flowability and processability when achieving the best mixing effect.

[0027] Furthermore, the outer surface of the drive motor 104 is fixedly connected to the upper part of the outer surface of the housing 102. Both the drive motor 104 and the servo motor 105e have protective shells 110 on their outer surfaces, with one side of each protective shell 110 fixedly connected to the outer surface of the housing 102. Multiple arc-shaped support plates are fixedly connected inside the base 101. The lower surface of the screw feeder 108 is fixedly connected to the upper surface of the support plates. The outer shell of the screw feeder 108 is made of insulating material. The protective shells 110 protect the drive motor 104 and the servo motor 105e, reducing motor damage and extending their service life. The arc-shaped support plates support the screw feeder 108, improving its stability.

[0028] During use, various raw materials are first placed inside the housing 102. Then, the drive motor 104 is started to drive the crushing roller 103 to process and crush the materials into relatively uniform small particles. The servo motor 105e is started, which drives the mixing component 105 through the gear 105f and the gear ring 105d. The raw materials are transported downwards by the spiral blades 105b. During the transport, preliminary mixing can be carried out, and the materials are preheated by the first heater 106. The mixing is carried out a second time by the stirring blades 105c. The materials are then transported into the spiral feeder 108 for a second mixing, which improves the mixing effect. At the same time, the second heater 109 can maintain the temperature of the materials, which facilitates processing and improves the quality of the product.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
