Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing, in particular to a raw material melting device for producing plastic products. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including all process products such as injection molding and blister molding using plastic as raw material. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fiber, it forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, with various additives added, which can be molded into a certain shape under certain temperature and pressure conditions. In the production process of plastic products, the raw materials often need to be melted at high temperature.

[0003] According to the Chinese patent publication number "CN216634997U", a patent document entitled "A raw material melting device for plastic product production" is disclosed. The device uses a heating component and a stirring component to accelerate the melting of rubber and plastic products. However, due to the lack of a crushing process for the raw materials, large-particle raw materials and fine raw materials are mixed. The time required for melting of large-particle raw materials and fine raw materials is different, making it impossible to melt the raw materials evenly. At the same time, the raw materials are easily blocked in the device during the transportation process, affecting the melting efficiency.

[0004] Therefore, we designed a raw material melting device for producing plastic products. Utility Model Content

[0022] Reference Figure 1-Figure 4 A plastic product production raw material melting device comprises a double-shaft motor 1 and a driving motor 2. The output end of the double-shaft motor 1 is connected to a first driving shaft 4. The first driving shaft 4 is coaxially mounted with a plurality of crushing blades 5. The double-shaft motor 1 is coaxially provided with a carrier frame 7. A crushing box 3 is provided at the top of the carrier frame 7. A feed pipe 11 is installed on the crushing box 3. The first driving shaft 4 passes through the crushing box 3. The crushing blades 5 are located in the crushing box 3. The bottom end of the crushing box 3 is inclined toward the feed pipe 11. The plastic product raw material is placed in the crushing box 3. The double-shaft motor 1 is driven to drive the first driving shaft 4. The first driving shaft 4 is driven to drive the first driving shaft 4. The rotation of the shaft 4 drives multiple crushing blades 5 to rotate, and the multiple crushing blades 5 crush the plastic product raw materials located in the crushing box 3. The installation position of the crushing blades 5 makes the crushed raw materials more uniform when crushing the plastic product raw materials, and prevents uneven melting of the plastic product raw materials due to the presence of large particles and fine particles. The crushed plastic product raw materials fall to the bottom of the crushing box 3. Due to the inclined design of the bottom of the crushing box 3, the crushed raw materials slide along the bottom of the crushing box 3 to the feed pipe 11, and fall into the conveying cylinder 14 through the feed pipe 11.

[0023] A processing box 6 is fitted at the bottom end of the dual-axis motor 1, and a fixing part 17 is fixed on the processing box 6. A circular hole is opened on the fixing part 17, and a conveying cylinder 14 is installed in the circular hole of the fixing part 17. The output end of the driving motor 2 is connected to a rotating shaft 12, and a spiral blade 13 is installed on the rotating shaft 12. The spiral blade 13 is located in the conveying cylinder 14, and a top cover 15 is installed on the top of the conveying cylinder 14. The rotating shaft 12 passes through the top cover 15, and a rectangular notch is opened on the top of the conveying cylinder 14. A discharge pipe 16 is installed at the bottom of the conveying cylinder 14, and the feed pipe 11 is connected to the rectangular notch at the top of the conveying cylinder 14. By driving the driving motor 2, the rotating shaft 12 rotates and drives the spiral blade 13 to rotate. The rotation of the spiral blade 13 pushes the raw material falling into the conveying cylinder 14 forward and downward. The shape design and conveying method of the spiral blade 13 prevent the raw material from being blocked, and it falls into the processing box 6 through the discharge pipe 16 at an orderly speed and in a stable manner.

[0024] A rectangular notch is provided on the processing box 6, and a discharge pipe 16 is connected to the rectangular notch on the processing box 6.

The heating component 9 is located in the processing box 6, and the heating component 9 is elliptical in shape. While driving the dual-axis motor 1, the dual-axis motor 1 drives the second driving shaft 8 to rotate synchronously. The rotation of the second driving shaft 8 causes the heating component 9 installed on the second driving shaft 8 to rotate synchronously. At the same time, the electric energy of the dual-axis motor 1 causes the heating component 9 to generate heat, and the crushed plastic product raw materials are heated and melted while being stirred. The shape design and movement mode of the heating component 9 make the melting effect of the plastic product raw materials more sufficient.

[0025] A hole is opened on the processing box 6, and the processing box 6 is connected to a sealing block 10, which is stuck in the hole. After the melting process of the plastic product raw material is completed, the sealing block 10 is manually rotated to separate the sealing block 10 from the processing box 6, so as to take out the plastic product raw material in the processing box 6.

[0026] The working principle of the utility model is as follows: the output end of the double-axis motor 1 is connected to the first driving shaft 4, and the first driving shaft 4 is coaxially installed with multiple crushing blades 5. The double-axis motor 1 is coaxially provided with a carrier frame 7, and a crushing box 3 is provided on the top of the carrier frame 7. A feeding pipe 11 is installed on the crushing box 3. A processing box 6 is fitted at the bottom end of the double-axis motor 1, and a fixing part 17 is fixed on the processing box 6. A circular hole is opened on the fixing part 17, and a conveying cylinder 14 is installed in the circular hole of the fixing part 17. The output end of the driving motor 2 is connected to the rotating shaft 12, and a spiral leaf 13 is installed on the rotating shaft 12. The spiral leaf 13 is located in the conveying cylinder 14, and the crushing blade 5 is driven by the first driving shaft 4 to rotate to crush the raw material, so that the raw material can be melted more evenly, and the rotating shaft 12 drives the spiral leaf 13 to move to prevent the raw material from being blocked.
