[0002] In the production process of PE wood-plastic products, the cooling link plays a vital role in product quality and production efficiency. The traditional one-time cooling method is often difficult to meet the production needs of products with complex shapes and high performance requirements. For example, in the shaping mold, relying solely on a single cooling method may lead to insufficient local cooling of the mold, causing the product to deform and have dimensional instability due to excessive temperature during the molding process, seriously affecting the appearance and performance of the product. In addition, the temperature control of PE wood-plastic raw materials during the transportation process is also relatively weak. Excessive raw material temperature may change its physical properties, thereby affecting the subsequent molding quality.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting a cooling mechanism, a water pump, a spray pipe and a spray head, when the PE wood-plastic mold is used, the cooling mechanism controls the cooling pipe to cool in the insulation layer through a refrigeration power supply, and transfers the low temperature to the raw materials in the feed pipe, thereby realizing the first cooling of the raw materials. This cooling process effectively reduces the temperature of the raw materials, prevents them from being deformed or changing in performance due to excessive temperature during transportation, and ensures the quality and performance of the products. At the same time, the water pump draws water from the water tank through the water pipe and injects the water into the spray pipe through the connecting pipe. The spray heads evenly distributed below the spray pipe spray water on the surface of the shaping mold to realize the second cooling of the mold. This dual cooling mechanism not only improves the cooling efficiency, but also ensures the uniformity of cooling, and avoids the problem of product quality degradation due to local overheating of the shaping mold.

In the present invention, by setting a reciprocating mechanism, when the PE wood-plastic mold is used, the motor is controlled to drive the reciprocating threaded rod to rotate. The thread groove of the reciprocating threaded rod cooperates with the guide block to convert the rotation into a linear reciprocating motion of the reciprocating slider. The reciprocating slider slides on the outer walls of the two support rods, driving the spray pipe and the spray head to move horizontally, ensuring that the cooling water can evenly cover the surface of the entire molding mold. This design not only improves the cooling efficiency, but also avoids the problem of local overheating of the mold caused by uneven distribution of cooling water. Through the precise control of the reciprocating mechanism, the stability of the molding mold in long-term use and the consistency of the product can be effectively guaranteed, significantly improving production efficiency and product quality. 3. In the present invention, by setting a feeding hopper and a stirring mechanism, when using the PE wood-plastic mold, the feeding hopper is used to store PE wood-plastic raw materials, and the output motor in the stirring mechanism drives the driving gear to rotate. The driving gear drives the three stirring rods to rotate in the feeding hopper through engagement with the driven gear, thereby fully stirring the raw materials. This stirring method not only expands the stirring area, but also improves the uniformity and efficiency of stirring, effectively preventing the raw materials from agglomerating or unevenly distributed. The stirred raw materials flow into the feeding pipe in the feeding mechanism through the inclined surface at the bottom of the feeding hopper, further ensuring the smooth transportation of the raw materials. Through the coordinated work of the feeding hopper and the stirring mechanism, high-quality raw materials can be provided for the subsequent mixing and shaping processes, thereby ensuring the performance and quality of the final product.

There are two feeding pipes 1701, and the two feeding pipes 1701 are respectively fixedly installed at the center position of the bottom of the two feeding bins 15. The two feeding pipes 1701 are both inclined in design and face each other. A conveying blade 1702 is rotatably connected between the inner walls of the feeding pipe 1701 and located at the center position thereof. Two driving motors 1703 are respectively fixedly installed at one end of the two feeding pipes 1701 away from each other, and the output end of the driving motor 1703 is connected to the conveying blade 1702.

[0016] The working principle of the present invention is as follows: when using the mold, the required materials are classified and injected into the two feeding bins 15, and the two stirring mechanisms 16 stir the materials in the two feeding bins 15 respectively. During the working process of the stirring mechanism 16, the output motor 1603 drives the driving gear 1602 to rotate between the inner walls of the support frame 1601, and the driving gear 1602 drives the two driven gears 1604 meshing with it to rotate, and the three stirring rods 1605 respectively follow the driving gear 1602 and the two driven gears 1604 to rotate, stirring the materials in the feeding bin 15. The materials are stirred and flow along the inclined surface at the bottom of the feed bin 15 into the feeding pipe 1701 in the feeding mechanism 17. The driving motor 1703 in the feeding mechanism 17 drives the conveying blades 1702 to rotate in the feeding pipe 1701.

The two feeding mechanisms 17 respectively convey two different materials to the mixing pipe 1801. The mixing motor 1803 drives the mixing blades 1802 to rotate in the mixing pipe 1801 to mix the two different materials. The material is delivered to the feed pipe 11 by the action of the conveyor 13 and injected into the shaping mold 2 for shaping. When the material flows through the feed pipe 11, the cooling mechanism 12 cools the material for the first time. During cooling, the refrigeration power supply 1204 controls several cooling pipes 1203 to refrigerate in the insulation layer 1201. The temperature is transferred to the material inside the feed pipe 11 through the feed pipe 11, thereby cooling the material in the feed pipe 11. During the shaping process, the water pump 10 draws water from the water tank 8 through the water pipe 9 and injects the water into the spray pipe 5 through the connecting pipe 7. The water flows from several spray heads below the spray pipe 5. 6 flows out and is poured on the top of the shaping mold 2. At the same time, the control motor 403 drives the reciprocating threaded rod 402 to rotate between the two fixed blocks 401. Under the guidance of the thread of the reciprocating threaded rod 402, the guide block 406 rotates above the reciprocating slider 405 and slides in the thread groove of the reciprocating threaded rod 402, thereby driving the reciprocating slider 405 to slide on the outer walls of the two support rods 404. The reciprocating slider 405 continuously moves back and forth horizontally on the outer walls of the support rods 404, driving the spray pipe 5 and the spray head 6 to cover the entire shaping mold 2 when sprinkling water for cooling, and the wood-plastic mold is used.
