Description

Technical Field

[0001] The invention relates to the technical field of wood plastic flooring, and in particular to a wood plastic flooring production device. Background Art

[0002] Wood plastic flooring is a new type of environmentally friendly composite material, mainly composed of wood fiber and plastic. It has the advantages of being waterproof, wear-resistant and weather-resistant, and has gradually become one of people's favorite flooring materials. The main raw materials of wood plastic flooring include wood fiber and plastic. Wood fiber can be sawdust, wood chips and other wood waste, while plastic mainly uses thermoplastic plastics such as polyethylene and polypropylene. The wood fiber and plastic particles are mixed, and the mixed raw materials are put into an extruder. The raw materials are extruded into shape through high temperature and high pressure. The extruded floor needs to be cooled and solidified to obtain the final product form.

[0003] In the existing technology, the wood-plastic flooring production equipment has uneven material mixing, which makes it difficult for the materials at the edge and bottom of the mixing box to be fully mixed with the central area, affecting the accuracy of the final product component ratio. In addition, the raw materials are easily adhered to the walls and bottom of the mixing box. As the number of production batches increases, the residual materials will affect the mixing quality of the new batch of raw materials, increase the instability of production, and also reduce the efficiency of equipment use. At the same time, a large amount of water used for cooling is directly discharged. The cooling water usually carries some fine particles and additives in the raw materials and other pollutants.

[0023] In this embodiment, the wood plastic flooring blank after extrusion molding is conveyed by the conveyor belt 706, and the second servo motor 705 is started to drive the pulley 703 at the rear to rotate, and the two pulleys 703 are rotated by the belt transmission, thereby driving the roller 702 to rotate, and the roller 702 drives the conveyor belt 706 to operate, and the wood plastic flooring blank moves backward on the conveyor belt 706, and the water in the water collection tank 714 is pumped out by starting the second self-priming pump 715, and is transported to multiple water nozzles 717 through the water pipe 716. The water nozzles 717 spray water on the wood plastic flooring blank passing through to cool it, and the waste water generated during the cooling process is discharged. , under the guidance of the guide plate 707, it flows from the inside of the cooling rack 701 to the center, and enters the wastewater collection tank 708 by starting the first self-priming pump 713. In the wastewater collection tank 708, the wastewater first passes through the filter screen 710 in the upper lifting box 709 to filter out larger particles of impurities, and then passes through the adsorption cotton 711 in the middle lifting box 709 to adsorb some fine impurities and some pollutants, and then passes through the activated carbon 712 in the lower lifting box 709 to further adsorb substances with color and odor. The treated part of the wastewater returns to the water collection tank 714 through the circulation pipe 719 under the action of the circulation pump 718, realizing the recycling of water resources.

[0024] In this embodiment, a placement rack 9 is provided at the center of the rear end of the cooling and molding structure 7, and a blowing structure 8 is provided at the front center of the upper end surface of the placement rack 9. The blowing structure 8 includes a mounting rack 801, which is provided at the front center of the upper end surface of the placement rack 9. A bellows 802 is provided at the center of the upper end surface of the mounting rack 801, an air inlet rack 803 is provided at the center of the upper end surface of the bellows 802, a suction fan 804 is provided at the center inside the air inlet rack 803, heaters 808 are provided at both sides of the center of the lower inner wall of the bellows 802, a fan pump 805 is provided at the center of the lower inner wall of the bellows 802, and the output end of the fan pump 805 passes through the lower inner wall of the bellows 802 and the upper end surface of the mounting rack 801 to the inside of the mounting rack 801, and The end is fixedly connected to an air delivery pipe 806, and a plurality of air nozzles 807 are arranged horizontally at the lower center of one side wall of the air delivery pipe 806. The cooled and formed wood plastic floor arrives on the placement rack 9, and the blowing structure 8 on the placement rack 9 starts to work. The suction fan 804 sucks air from the air inlet rack 803 into the bellows 802, and the air is heated by the heater 808 inside the bellows 802. The fan pump 805 transports the heated air through the air delivery pipe 806 to the plurality of air nozzles 807. The air nozzles 807 blow hot air to the wood plastic floor to dry the wood plastic floor so that it reaches a more ideal use state, completing the whole production process of the wood plastic floor from raw material mixing to final forming and drying.

[0025] Implementation plan: By starting the first servo motor 301 to rotate and drive the stirring rod 302 to rotate together in the mixing box 1, by preparing wood particles and plastic raw materials or polyethylene, adding additives such as preservatives and UV inhibitors, and adding these raw materials to the mixing box 1 through the feed hopper 2, a plurality of connecting frames 303 are arranged in the center of the front end and rear end faces of the stirring rod 302, and these connecting frames 303 rotate synchronously with the stirring rod 302. The stirring plates 305 arranged obliquely on the connecting frames 303 stir the materials during the rotation of the connecting frames 303, so that different raw materials can be initially mixed and blended. The inclined setting of the stirring plates 305 helps to drive the materials from different angles and promote more complete mixing. 02 The threaded rod 308 is threadedly sleeved at the center of the lower end face and the spiral agitator 309 is located at the lower center of the outer wall. When the stirring rod 302 rotates, the spiral agitator 309 drives the material from bottom to top, further disrupting the material distribution state, enhancing the mixing effect, and ensuring the uniformity of material mixing. The rotation of the stirring rod 302 drives the scraper 310 to rotate. During the stirring process, the scraper 310 always adheres to the inner wall of the mixing box 1, and can scrape off the material attached to the inner wall of the mixing box 1, ensuring that all materials participate in the mixing process, preventing local material accumulation or insufficient mixing. After the material is fully mixed in the mixing box 1, it is conveyed to the extruder 5 at the lower center of the rear end through the feed pipe 4 at the center of the lower end face of the mixing box 1.

[0026] The extruder 5 receives the mixed material delivered from the mixing box 1. In the extruder 5, the material is subjected to high temperature and high pressure to further plasticize. The high temperature makes the plastic raw material reach a molten state and fully fuses with the wood particles. Under the pressure, the material is pushed through a specific channel to the extruder 6 at the center of the rear end. The material entering the extruder 6 is extruded by the extruder 6 according to the pre-set mold shape. Through the specific mold, the material is given the required shape of the wood plastic floor, such as the common plate shape, and the green body of the wood plastic floor is initially formed. After this step, a product prototype with a basic shape of the wood plastic floor is produced.

[0027] The wood plastic flooring blank after extrusion molding falls on the conveyor belt 706 of the cooling molding structure 7. By starting the second servo motor 705, the pulley 703 at the rear is driven to rotate. The pulley 703 at the rear drives the pulley 703 in front and the roller 702 to rotate through the belt, so as to realize the operation of the conveyor belt 706, thereby driving the wood plastic flooring blank to move along the conveyor belt 706 to the rear end of the cooling rack 701. In the process of the wood plastic flooring blank moving along the conveyor belt 706, the cooling begins to take effect. The second self-priming pump 715 pumps water from the water collection tank 714, and the water is transported to multiple water nozzles 717 through the water pipe 716. The water nozzles 717 spray water to the wood plastic flooring blank passing by, and use the water to absorb the heat of the blank to reduce the temperature of the blank, thereby realizing cooling and shaping, ensuring that the shape of the floor is fixed and the physical properties are stable. The generated wastewater flows toward the center of the cooling rack 701 under the guidance of the guide plate 707 inclinedly arranged on the lower inner wall of the cooling rack 701. The wastewater in the cooling rack 701 is pumped into the wastewater collection tank 708 by starting the first self-priming pump 713. A three-layer lifting box 709 device is provided inside the wastewater collection tank 708 to purify the wastewater. The filter screen 710 in the upper lifting box 709 first filters out larger particles of impurities, and the adsorption cotton 711 in the middle lifting box 709 further adsorbs fine impurities and some pollutants. The activated carbon 712 in the lower lifting box 709 deeply adsorbs the color, odor and residual pollutants in the wastewater. The treated wastewater is transferred back to the water collection tank 714 through the circulation pipe 719 under the action of the circulation pump 718, thereby realizing the recycling of water resources, saving resources and reducing production costs.

[0028] The cooled and formed wood plastic flooring is transported to the placement rack 9 at the rear center of the cooling and forming structure 7. The suction fan 804 is activated to suck outside air into the bellows 802. The air is heated by the heater 808 in the bellows 802. The fan pump 805 transports the heated air out through the air duct 806. Multiple air nozzles 807 arranged laterally on one side wall of the air duct 806 blow the hot air evenly toward the wood plastic flooring, so that the moisture of the wood plastic flooring is further dissipated and a relatively ideal drying state is achieved to meet the final use requirements and improve the quality of the flooring.

[0029] In addition, the control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0030] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0031] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
