Description

Technical Field

[0001] This invention relates to the field of high-strength wood-plastic composite flooring processing technology, specifically a method for processing high-strength wood-plastic composite flooring. Background Technology

[0002] Wood-plastic composite flooring is a new type of environmentally friendly composite material product. Its raw materials include wood powder and recycled plastic produced during the production of medium- and high-density fiberboard. The wood powder and recycled plastic are granulated into wood-plastic composite material by a granulation device, and then processed into wood-plastic flooring through an extrusion molding process. This product combines the wood texture of wood with the water-resistant and corrosion-resistant properties of plastic, and is suitable for outdoor waterproof and corrosion-resistant building materials.

[0003] The processing methods for wood-plastic composite flooring mainly include: material preparation, mixing and stirring, extrusion molding, cooling and shaping, surface treatment and cutting and packaging. Among these, cooling and shaping determines the dimensional accuracy, mechanical properties, surface quality and production efficiency of the wood-plastic composite flooring. Therefore, cooling and shaping plays a crucial role in the processing of wood-plastic composite flooring.

[0004] Traditional cooling molding methods typically combine water cooling and air cooling. Cooling water is piped to the upper surface of the flooring blank. As the water flows, it carries away the heat from the part of the flooring blank that is in contact with the cooling water, thus achieving heat exchange and cooling. Then, air cooling is used for further cooling. However, after the cooling water comes into contact with the upper surface of the flooring blank, it is easy to form eddies or stagnant areas when flowing on the upper surface, resulting in insufficient contact with the lower surface of the blank. This leads to poor cooling effect on the lower surface of the flooring blank and uneven cooling of the entire flooring blank, affecting the curing quality of the flooring blank. Secondly, throughout the cooling process, the cooling water is piped to the upper surface of the flooring blank, which requires a continuous supply of cooling and relies on the operation of a cooling tower, resulting in a large workload for the cooling tower. Summary of the Invention

[0005] In view of the above problems, this application provides a method for processing high-strength wood-plastic composite flooring to solve the technical problems of high cooling costs and uneven cooling effects in related technologies.

[0016] According to an embodiment of the present invention, the cooling rack includes a rotating shaft. The rotating shaft is rotatably connected to the right side of the cooling water tank and above the horizontal partition plate.

[0021] As can be seen from the above technical solutions, the present invention has the following advantages:

[0022] 1. In this invention, the water-cooling unit ensures that the upper and lower surfaces of the floor blank are in complete contact with the cooling water, avoiding the formation of local eddies or stagnant areas in the cooling water during the flow process due to the shape and size of the floor blank, which would prevent the cooling water from reaching the lower surface of the blank. The air-cooling unit further cools and dries the upper and lower surfaces of the floor blank. The cooling water tank is divided into three sections by the partition unit, which respectively store cooling water, cooling water whose temperature rises after heat exchange, and cooling water for cooling treatment, thereby reducing the amount of cooling water required and lowering the cooling cost. At the same time, it avoids the cooling water that has risen after heat exchange from being directly close to the floor blank, which would result in poor cooling effect on the lower surface of the floor blank.

[0023] 2. In this invention, the bidirectional screw is rotated according to the width of the floor blank to adjust the distance between the annular pressure plates. With the cooperation of the guide column and the annular pressure plate, the floor blank is guided and conveyed. Cooling water is sprayed onto the upper and lower surfaces of the floor blank through staggered nozzles, ensuring that the upper and lower surfaces of the floor blank are in complete contact with the cooling water while saving the amount of cooling water required during cooling.

A cooling rack 27 is provided on the right side of the inner end of the cooling water tank 1 to cool the cooling water after heat exchange. A guide rack 28 is provided on the left side of the inner end of the cooling water tank 1 to guide and limit the floor blank. A drain pipe 29 is fixedly installed on the left end of the cooling water tank 1 and above the horizontal partition plate 21. A water supply pipe 30 is fixedly installed on the left end of the cooling water tank 1 and below the horizontal partition plate 21. The drain pipe 29 is fixedly connected to the cooling tower. Roller conveyors are provided on both the left and right sides of the cooling water tank 1. The cooling tower and roller conveyors are existing technologies and are not shown in the attached drawings.

[0042] See Figure 3 and Figure 5 The water-cooling unit 3 includes a vertical pipe 31. The vertical pipe 31 is fixedly installed on the left side of the inclined guide plate 241 and the horizontal partition plate 21. A water spray frame 32 is fixedly installed at the inner end of the cooling water tank 1 and directly above the vertical pipe 31. A water pump 33 is fixedly installed at the lower end of the water spray frame 32. A waterproof cover is fixedly installed at the upper end of the water pump 33. The water pump 33 is fixedly connected to the vertical pipe 31. A second water spray frame 34 is fixedly installed at the upper end of the cooling water tank 1 through an inverted L-shaped plate. A water pipe 35 is fixedly installed at the upper end of the second water spray frame 34.

[0043] See Figure 4 The first water spray frame 32 includes a king-shaped pipe frame 321. The king-shaped pipe frame 321 is fixedly installed at the inner end of the cooling water tank 1 and directly above the vertical pipe 31. The upper end of the water pipe arranged in the front-back direction on the king-shaped pipe frame 321 is uniformly fixedly installed with nozzles 322 along its linear direction. The nozzles 322 are arranged alternately between adjacent left and right sides. The structure of the second water spray frame 34 is the same as that of the first water spray frame 32, except that the setting direction of the nozzles 322 of the second water spray frame 34 is opposite to that of the first water spray frame 32.

[0044] See Figure 4 and Figure 6 The guide frame 28 includes a guide post 281. The guide post 281 is rotatably connected to the front and rear sides of the left side of the inner end of the cooling water tank 1. A bidirectional screw 282 is rotatably connected to the middle of the guide post 281. One end of the bidirectional screw 282 penetrates the side wall of the cooling water tank 1. A circular plate 283 is symmetrically threaded on the bidirectional screw 282. A connecting block 284 that penetrates the guide post 281 is uniformly fixedly installed on the outer end of the circular plate 283 along its circumference. An annular pressure plate 285 is fixedly connected to the end of the connecting block 284 on the same side away from the circular plate 283.

[0045] Based on the width of the floor blank, rotate the bidirectional screw 282 to adjust the distance between the annular pressure plates 285. At this time, the floor blank extruded from the die head mold enters the cooling equipment under the conveyor of the roller conveyor. With the cooperation of the guide column 281 and the annular pressure plate 285, the conveying and guiding of the floor blank is further assisted. When the floor blank enters between the upper and lower king-shaped tube racks 321, the cooling water is sprayed onto the upper and lower surfaces of the floor blank through the staggered nozzles 322 to ensure that the upper and lower surfaces of the floor blank are in contact with the cooling water.

[0046] See Figure 3 and Figure 5The air-cooled unit 4 includes U-shaped tubes 41. The upper right side of the cooling water tank 1 is fixedly installed with U-shaped tubes 41 evenly arranged from right to left through a connecting plate. The left end of the U-shaped tubes 41 is evenly fixedly installed with inclined jet heads 42 along its trajectory. The nozzles of the jet heads 42 face the center. The lower left end of the rightmost U-shaped tube 41 is fixedly installed with a connecting pipe 43 between it and the adjacent U-shaped tube 41. The upper left end of the middle U-shaped tube 41 is fixedly installed with a connecting pipe 44 between it and the leftmost U-shaped tube 41.

[0047] See Figure 4 and Figure 5 The cooling rack 27 includes a rotating shaft 271. The rotating shaft 271 is rotatably connected to the right side of the cooling water tank 1 and located above the horizontal partition plate 21. A set of fixed rods is uniformly fixed along the linear direction of the outer left end of the rotating shaft 271. Each set of fixed rods consists of connecting rods 272 evenly arranged around the circumference of the rotating shaft 271. A circular conveyor plate 273 is fixedly installed on the end of the connecting rods 272 on the same set of fixed rods away from the rotating shaft 271. A water tank 274 is evenly provided on the end of the circular conveyor plate 273 away from the rotating shaft 271. Ventilation slots 275 are symmetrically arranged on the cooling water tank 1 and in front of and behind the annular conveyor plate 273. An exhaust pipe 276 is fixedly installed on the right side of the vertical partition plate 24. An exhaust port 277 is evenly arranged at the lower end of the exhaust pipe 276 and directly above the annular conveyor plate 273. A rotating cylinder 278 is linearly and evenly connected from right to left on the right side of the cooling water tank 1 and below the rotating shaft 271. A stirring plate 279 is evenly fixedly installed on the outer end of the rotating cylinder 278 along its circumference. A sprocket is fixedly installed at the front end of the rotating cylinder 278. The sprocket is connected by a toothed chain belt. A temperature measuring instrument is set on the right side of the cooling water tank 1 and on the right side of the vertical partition plate 24. The sprocket, toothed chain belt and temperature measuring instrument are all prior art and are not shown in the attached drawings.

[0048] The floor blank continues to move to the right under the conveyor belt. After being water-cooled, the portion moves to the right and enters the U-shaped pipe 41. Pressurized gas is introduced into the U-shaped pipe 41 and the exhaust pipe 276 by an external air pump. Air is blown onto the surface of the floor blank through the jet nozzle 42, cooling the floor blank and accelerating its surface drying. The cooling water that has come into contact with the floor blank and exchanged heat drips down onto the surface of the inclined guide plate 241. Under the action of gravity, the cooled water enters the space on the upper surface of the horizontal partition plate 21 that matches the cooling water tank 1. Most of the cooled water after heat exchange is located on the vertical partition plate. On the left side of 24, a small amount of cooling water that did not flow down in time drips onto the right side of the vertical partition plate 24 under the action of wind and gravity when the floor blank moves to the vicinity of the jet head 42. At the same time, valve 26 on the connecting pipe 25 is opened, allowing the cooling water on the left side of the vertical partition plate 24 to flow to the right side of the vertical partition plate 24. When the amount of cooling water on the right side of the vertical partition plate 24 reaches the amount that can be cooled, valve 26 is closed. A large amount of cooling water on the surface of the floor blank enters the cooling water tank 1, and a small amount flows to the left along the floor blank and drips onto the ground to the left of the cooling water tank 1. Since the amount is small, it can be ignored or a water tank can be set up for recycling.

[0049] See Figure 4 A fixed cylinder 211 is uniformly fixedly installed at the lower end of the horizontal partition plate 21 along its linear axis. A floating plate 212 is slidably connected up and down on the fixed cylinder 211. The floating plate 212 has a hollow structure.

[0050] See Figure 1 The cooling water tank 1 has rectangular slots at both ends of the floating plate 212, and transparent glass 11 is fixedly installed in the rectangular slots.

[0051] At this time, the externally installed motor drives the rotating shaft 271 to rotate, thereby driving the annular conveyor plate 273 to rotate. The water tank 274 on the annular conveyor plate 273 carries the cooling water on the right side of the vertical partition plate 24 to the surface, so that it comes into contact with the air discharged from the exhaust port 277 on the exhaust pipe 276, accelerating its cooling. At the same time, the ventilation slot 275 accelerates the airflow, further accelerating the cooling speed of the cooling water. The rotating cylinder 278 drives the stirring plate 279 to rotate, stirring the cooling water to ensure the cooling of the right side of the vertical partition plate 24. After the water is completely cooled, the temperature is measured using a temperature measuring instrument. When the cooling water temperature on the right side of the vertical partition plate 24 reaches the initial temperature, valve 23 is opened, allowing the cooled water to flow below the horizontal partition plate 21. Since some cooling water evaporates during air cooling, the total amount of cooling water in the cooling water tank 1 gradually decreases, resulting in a gradual decrease in the amount of cooling water below the horizontal partition plate 21. The downward movement of the floating plate 212 can be observed through the transparent glass 11. The displacement change reaches its maximum. When the value changes significantly, cooling water is supplied to the space below the horizontal partition plate 21 in the cooling water tank 1 through the water supply pipe 30. When the amount of floor blank to be cooled is small, a connecting channel is provided at the front end of the cooling water tank 1 below the horizontal partition plate 21, and the other end of the connecting channel is fixedly connected to the water pipe 35. When the amount of floor blank to be cooled is large, the water pipe 35 is connected to the external cooling water source. The cooling water below the horizontal partition plate 21 is only used by the spray frame 32. At this time, the amount of cooling water above the horizontal partition plate 21 increases rapidly after heat exchange. Most of the cooling water after heat exchange is sent to the external cooling tower for cooling through the drain pipe 29. Since the area of ​​the local vortex or stagnant area formed by the cooling water during the flow process is smaller than that of the lower surface of the floor blank, the method of using external cooling water to cool the upper and lower surfaces of the floor blank is less efficient than using the cooling water below the horizontal partition plate 21 to cool the lower surface of the floor blank. It also increases the workload of the cooling tower.
