Description

Technical Field

[0001] This utility model relates to the field of foam processing technology, specifically to a foaming machine for foam processing. Background Technology

[0002] Foamed plastics are one of the raw materials for many products. They are molded into finished products through injection molding. Products made from foamed plastics are used in many fields. During the processing of foamed plastics, a foaming machine is needed to expand the material. A foaming machine is a device that turns a foaming agent into foam by applying an aqueous solution of a certain concentration. The foaming agent itself cannot become foam on its own; it must be produced by the mechanical action of the foaming machine. Therefore, the foaming machine is a device specifically designed for foaming foamed plastics and is very important for the processing of foamed plastics.

[0003] In order to mix the foaming material and ensure the uniformity of the mixture, a stirring structure is set inside the foaming machine. The stirring structure of traditional foaming machines is mostly a simple rod-type stirring bar, which has a relatively limited function. After the material is discharged, there will be material residue on the inner wall of the hopper. The stirring bar alone cannot clean the material on the inner wall. It is necessary to clean it by injecting water or manually, which is not only very inconvenient to operate, but also wastes materials. Therefore, a foaming machine for foam processing is proposed.

[0024] Example

[0025] Please see Figure 1-5 This utility model provides a technical solution: a foaming machine for foam processing, comprising a mixing cylinder seat 1, a pressure box seat 2, and an injection head 3, as shown in the attached figure. Figure 1 As shown, the mixing cylinder seat 1 is cylindrical. To facilitate the heating treatment of the material inside the mixing cylinder seat 1, heating rings 14 are fixedly installed at equal intervals on the inner wall sandwich side of the mixing cylinder seat 1. To facilitate the feeding of materials, a main feeding port 12 is provided at the upper part of the mixing cylinder seat 1, and a secondary feeding port 11 is provided on the side of the mixing cylinder seat 1. Both the main feeding port 12 and the secondary feeding port 11 are connected to the inner cavity of the mixing cylinder seat 1.

[0026] Both the booster box 2 and the injection head 3 are connected to the discharge side of the mixing drum 1 via pipelines, as detailed in the attached diagram. Figure 2 As shown, the bottom of the mixing cylinder seat 1 is inverted conical. A discharge port 13 is provided at the lower part of the mixing cylinder seat 1. A conveying pipe 16 is fixedly connected to the lower part of the discharge port 13. The end of the conveying pipe 16 is connected to the inlet end of the pressure chamber seat 2. The pressure chamber seat 2 is used for pressurizing the material. To facilitate the supply of pressurized gas, a pressurization interface is provided at the rear of the pressure chamber seat 2. The foaming agent is pressurized by a compressor or other pressurizing equipment to reach a certain pressure level. Pressurization can increase the gas content in the foaming agent and improve the stability of the foam. The injection head 3 is fixedly installed at the lower part of the pressure chamber seat 2 for precise dispensing of the foaming material. The upper part of the injection head 3 is connected to the outlet end of the pressure chamber seat 2. The injection head 3 is a worm gear-type quantitative injection device. To facilitate the foaming and molding of the material, a molding die 17 is provided below the injection head 3.

[0027] To facilitate material mixing, a stirring mechanism is installed inside the mixing drum 1. This stirring mechanism includes a drive motor 4, a stirring rod 5, a mounting shaft 6, a cleaning plate 7, and a cleaning scraper 8, as shown in the attached diagram. Figure 1 As shown, the drive motor 4 is fixedly installed on the top side of the mixing drum 1 by bolts. The drive shaft 15 is fixedly installed on the shaft end of the drive motor 4. The stirring rod 5 is fixedly installed on the upper part of the drive shaft 15. The stirring rod 5 is rotated and installed inside the mixing drum 1 under the drive of the drive motor 4. It adopts an internal stirring structure. The stirring rod 5 is set inside the mixing drum 1. During operation, the drive motor 4 drives the stirring rod 5 to stir and mix the materials in the mixing drum 1, which can effectively improve the mixing and foaming effect of the materials.

[0028] To facilitate the connection and installation of the shaft post 6, see attached... Figure 4As shown, each of the two sets of end rods of the stirring rod 5 has a shaft mounting hole extending through its upper part. The mounting shaft 6 is movably inserted and installed inside the shaft mounting hole. To facilitate connection and installation with the mounting shaft 6, a mounting bushing is provided on the side of the cleaning plate seat 7. The cleaning plate seat 7 is fastened to the upper part of the mounting shaft 6 by the mounting bushing and bolts. The cleaning scraper 8 is detachably installed on the side of the cleaning plate seat 7. The cleaning plate seat 7, along with the cleaning scraper 8, is flipped and installed on the end rod side of the stirring rod 5 via the mounting shaft 6, for scraping and cleaning residual materials on the inner wall of the mixing drum seat 1.

[0029] To limit the rotation angle of the cleaning plate base 7, a limiting head 9 is provided on the upper part of the mounting post 6 for limiting the rotation of the mounting post 6, as shown in the attached figure. Figure 5 As shown, the limiting head seat 9 is fixedly installed on the upper end of the mounting shaft column 6. The bottom of the limiting head seat 9 is fixed with a limiting column. The upper part of the end rod of the stirring rod 5 is provided with a limiting ring groove 10. After installation, the limiting column is fitted into the inner side of the limiting ring groove 10. The cleaning scraper 8 follows the cleaning plate seat 7 and is installed by flipping and rotating with the stirring rod 5 through the mounting shaft column 6. With the corner limiting of the limiting head seat 9, when rotating in the forward direction, the cleaning plate seat 7 is pushed and flipped by the material and keeps parallel to the material flow direction, which will not affect the operation of the stirring rod 5. When rotating in the reverse direction, the limiting head seat 9 limits the cleaning plate seat 7 and prevents it from flipping in the reverse direction. The limiting action makes the cleaning scraper 8 stick to the inner wall of the mixing drum seat 1, which can scrape and clean the material remaining on the inner wall of the mixing drum seat 1. No manual cleaning is required and the material can be cleaned and recycled, which is conducive to improving the convenience of cleaning and the completeness of material discharge of the device.

[0030] Working principle or structural principle: During operation, the main material is first added into the mixing cylinder 1 through the main inlet 12. Then, the material in the mixing cylinder 1 is heated by the heating ring 14 and stirred by the stirring rod 5. After the material reaches the required level, the auxiliary material is precisely added into the mixing cylinder 1 through the auxiliary inlet 11. The mixing and stirring of the stirring rod 5 and the heating of the heating ring 14 work together to complete the mixing and foaming of the material through reaction. When the material is to be used, the solenoid valve at the bottom of the mixing cylinder 1 is opened, and the material enters the pressure chamber 2 through the conveying pipe 16. In the pressure chamber 2, high-pressure gas is introduced to improve the foaming characteristics of the material. Then, the material is quantitatively injected into the molding mold 17 through the injection head 3, and the product processing is completed through the foaming effect.

[0031] During the mixing process, when the stirring rod 5 rotates in the forward direction, the cleaning plate seat 7 is pushed by the material to rotate axially along the mounting shaft 6. After reaching a certain angle, the locking pin at the bottom of the limiting head seat 9 engages with the end side of the limiting ring groove 10, thereby limiting the rotation of the cleaning plate seat 7. At this time, the cleaning plate seat 7 remains parallel to the material flow direction and will not affect the operation of the stirring rod 5. After the material is discharged, when cleaning the residual material in the mixing drum seat 1, the stirring rod 5 rotates in the reverse direction. Due to the rotational inertia, the cleaning plate seat 7 rotates in the reverse direction, causing the cleaning scraper 8 to contact the inner wall of the mixing drum seat 1. At the same time, it is limited by the locking pin at the bottom of the limiting head seat 9, which can provide stable limiting support for the cleaning plate seat 7. The cleaning scraper 8 scrapes and cleans the residual material on the inner wall of the mixing drum seat 1. The material is scraped and gathered by the cleaning scraper 8 and flows down to the bottom of the mixing drum seat 1 for recycling.

[0032] In summary, this foaming machine adopts an internal stirring structure. A stirring rod 5 is installed inside the mixing drum 1. During operation, the stirring rod 5 is driven by the drive motor 4 to stir and mix the materials inside the mixing drum 1, effectively improving the mixing and foaming effect. A cleaning plate seat 7 and a cleaning scraper 8 are installed at the end of the stirring rod 5. The cleaning scraper 8 follows the cleaning plate seat 7 and is rotated and installed with the stirring rod 5 via the mounting shaft 6. With the corner limiting of the limiting head seat 9, during forward rotation, the cleaning plate seat 7 is pushed and rotated by the material, maintaining parallel to the material flow direction and not affecting the operation of the stirring rod 5. During reverse rotation, the limiting head seat 9 prevents the cleaning plate seat 7 from flipping backward. The limiting action causes the cleaning scraper 8 to adhere to the inner wall of the mixing drum 1, enabling the scraping and cleaning of residual material on the inner wall of the mixing drum 1. This eliminates the need for manual cleaning and allows for material recovery, improving the ease of cleaning and completeness of material discharge.
