Description

Technical Field

[0001] This utility model relates to the field of PE outdoor flooring production technology, specifically a co-extrusion device for PE outdoor flooring production. Background Technology

[0002] A co-extrusion unit for producing PE outdoor flooring mainly consists of an extruder, a co-extrusion die, a mold, a cooling and shaping system, and a traction and winding system. The extruder melts and plasticizes the PE raw material and extrudes it. The co-extrusion die allows various PE materials or additives with different properties to be co-extruded and compounded, forming a multi-layered flooring material prototype. The mold gives the flooring a specific shape and size. The cooling and shaping system uses air cooling, water cooling, or other methods for rapid cooling to fix the shape of the flooring. The traction and winding system pulls the flooring forward at a stable speed and winds it up, ensuring that the produced PE outdoor flooring has stable quality, a reasonable structure, a smooth surface, and good outdoor performance.

[0003] In the existing technology, when workers use co-extrusion equipment to produce PE outdoor flooring, the mixing process is simply carried out by stirring with a stirring rod. Some raw materials adhere to the inner wall of the barrel, resulting in insufficient mixing of some materials and affecting production quality. When changing raw materials, the mixing barrel needs to be cleaned. The traditional cleaning method is to simply clean it by stirring, which cannot remove some impurities adhering to the inner wall, thus allowing it to be used again and causing a significant reduction in production quality. In order to solve this technical problem, this utility model proposes a co-extrusion device for the production of PE outdoor flooring. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a co-extrusion device for the production of PE outdoor flooring. It has the following beneficial effects:

[0015] (1) The motor is installed on the top of the high-speed mixing tank. When the motor is started, it drives the rotating rod to rotate. The rotating rod causes the connecting plate and the scraper to rotate. The scraper scrapes the raw material off the tank wall and the auxiliary stirring rod fully mixes the raw material, which solves the problems of uneven mixing and material residue. Traditional devices often cause product quality fluctuations due to insufficient mixing and the material is easy to accumulate on the wall surface, affecting the next mixing. The air pump extracts the air in the tank through the exhaust pipe, which is conducive to the raw material entering as needed in a vacuum environment. It can also avoid oxidation in specific processes. When discharging, valve one is opened and the raw material flows out through the discharge pipe. When cleaning, the water inlet pipe and valve two are opened to inject water. The motor drives the scraper to clean the impurities on the inner wall, which solves the problem of difficult cleaning. Traditional devices are difficult to effectively clean stubborn dirt in the tank. This combination improves the mixing quality and efficiency, simplifies operation and maintenance, and ensures stable production and product consistency.

[0016] (2) Vacuum environments are created by vacuum pumps for PE1, PE2, PE3 and lime storage tanks. The corresponding raw materials enter the corresponding storage tanks through their respective feed hoppers by means of air pressure difference. This solves the problems of raw material storage being easily affected by air and inconvenient feeding. Traditional devices may cause raw material deterioration or feeding difficulties due to air mixing. When the high-speed mixing tank is working, the control valve is opened as needed, and the raw materials enter through the discharge pipe under air pressure. This design accurately controls the raw material ratio and conveying, solving the problems of inaccurate raw material ratio and unstable conveying in traditional mixing devices. It improves production flexibility and accuracy. The storage tanks and the high-speed mixing tank cooperate with each other to optimize the raw material storage, conveying and mixing process of the entire PE outdoor flooring production, improve production efficiency and product quality stability, reduce the defect rate caused by raw material links, and reduce production costs and resource waste.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A co-extrusion device for producing PE outdoor flooring includes a support platform 1, a bracket 27 externally mounted on the support platform 1, a high-speed mixing tank 17 fixedly connected inside the bracket 27, a motor 18 fixedly connected to the top of the high-speed mixing tank 17, a rotating rod 21 fixedly connected to the output end of the motor 18, a connecting plate 22 fixedly connected to the outer wall of the rotating rod 21, a scraper 23 fixedly connected to the other end of the connecting plate 22, a stirring rod 24 fixedly connected to the outer wall of the rotating rod 21, both the stirring rod 24 and the scraper 23 being rotatably connected inside the high-speed mixing tank 17, a vacuum pump 19 fixedly connected to the top of the high-speed mixing tank 17, an exhaust pipe 20 fixedly connected to the output end of the vacuum pump 19, and the exhaust pipe 20 passing through the vacuum pump 19 and extending into the high-speed mixing tank 17, a water inlet pipe 13 fixedly connected to the top of the high-speed mixing tank 17, a valve 21 externally mounted on the water inlet pipe 13, and a discharge pipe 25 fixedly connected to the bottom of the high-speed mixing tank 17, a valve 16 externally mounted on the discharge pipe 25.

[0025] Turn on the motor 18 at the top of the high-speed mixing tank 17. The motor 18 drives the rotating rod 21 to rotate. During rotation, the rotating rod 21 drives the connecting plate 22 and the scraper plate 23 to rotate together. The rotation of the scraper plate 23 scrapes off the raw materials adhering to the inner wall of the high-speed mixing tank 17, ensuring thorough mixing. The stirring rod 24 also stirs at high speed, further ensuring more uniform and thorough mixing. During high-speed rotation, the temperature inside the mixing tank gradually rises, heating the raw materials to a molten state, making them fluid. When it is necessary to discharge the raw materials, open valve 1 26, and the molten raw materials will be discharged through the discharge pipe 25 for use. When it is necessary to clean the inside of the high-speed mixing tank 17, open the water inlet pipe 13, and water will enter the high-speed mixing tank 17 through valve 2 11. At this point, the motor 18 is started again, and the motor drives the scraper 23 to rotate. The scraper 23 can clean the impurities on the inner wall of the high-speed mixing barrel 17. Through the coordinated operation of these components, the efficiency of the entire production process is significantly improved.

[0026] Example 2: The difference between this example and Example 1 is that, in this example, two bases 14 are fixedly connected to the top of the support platform 1, and feed hoppers 10 and 12 are fixedly connected inside the two bases 14 respectively. Four bases 6 are fixedly connected to the top of the support platform 1, and PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5 are fixedly connected inside the four bases 6 respectively. Feed hoppers 10 and 12 are fixedly connected to the top of each of the PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5. The material bins 9 and four feed bins 9 are respectively connected to feed hopper 10 and feed hopper 2 12 through feed pipes 7. At the same time, vacuum pumps 8 are installed on the top of PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5. Discharge pipes 15 are fixedly connected to the bottom of PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5. A control valve 16 is fixedly connected to the outer wall of each discharge pipe 15. The other end of the discharge pipe 15 passes through the high-speed mixing tank 17 and extends into the high-speed mixing tank 17.

[0027] Pour PE1, PE2, PE3 and lime into their respective feed hoppers, namely feed hopper 10 and feed hopper 212. These feed hoppers are supported on support platform 1 by base 214. Turn on vacuum pump 8, which will extract the air from PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5, creating a vacuum environment inside these storage tanks. The pressure difference generated in this vacuum environment causes the raw materials in the feed hopper 10 and feed hopper 2 to flow along the conveying pipe 7 into the corresponding PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4 and lime storage tank 5 for storage. These storage tanks are fixedly supported on the support platform 1 by the base 16. The vacuum pump 19 on the top of the high-speed mixing tank 17 is started. The vacuum pump 19 will extract the air in the high-speed mixing tank 17 and discharge it through the exhaust pipe 20, so that the inside of the high-speed mixing tank 17 is also kept in a vacuum state. According to the needs of making PE outdoor flooring, the staff selectively open the corresponding control valve 16. Under the action of air pressure, the corresponding raw materials will enter the high-speed mixing tank 17 through the discharge pipe 15 for mixing.

[0028] Working principle: When using this device, PE1, PE2, PE3, and lime are first poured into the corresponding feed hoppers 10 and 12, respectively. They are supported on the support platform 1 by base 2 14. Then, the vacuum pump 8 is turned on, which extracts air from the PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4, and lime storage tank 5, maintaining a vacuum state. The air pressure then forces the raw materials in feed hoppers 10 and 12 to flow through the conveying pipe 7 into the corresponding PE1 storage tank 2, PE2 storage tank 3, PE3 storage tank 4, and lime storage tank 5 for storage. These tanks are then fixedly supported on the support platform 1 by base 1 6. Next, the vacuum pump 19 on top of the high-speed mixing tank 17 is activated, extracting air from inside the high-speed mixing tank 17 and discharging it through the exhaust pipe 20, maintaining a vacuum. The control valve is then opened according to the PE outdoor flooring to be manufactured. 16. The corresponding raw materials enter the high-speed mixing tank 17 under air pressure through the discharge pipe 15. At this time, the motor 18 on the top of the high-speed mixing tank 17 is started. Under the action of the motor 18, the rotating rod 21 is rotated. When the rotating rod 21 rotates, it will drive the connecting plate 22 and the scraper 23 to rotate. The scraper 23 will scrape off the raw materials adhering to the inner wall of the high-speed mixing tank 17 to make them fully mixed. Combined with the high-speed stirring of the stirring rod 24, the mixing is more thorough. The high-speed rotation will also raise the internal temperature, thereby heating the raw materials to a melting state and making them fluid. The raw materials are discharged through the discharge pipe 25 by opening the valve 1 26. When it is necessary to clean the inside of the high-speed mixing tank 17, the water supply pipe 13 is opened, and water is added to the high-speed mixing tank 17 through the valve 2 11. The motor 18 is started to drive the scraper 23 to rotate, which cleans the impurities on the inner wall of the high-speed mixing tank 17. Through the cooperation of these, the working efficiency is improved.
