Description

Technical Field

[0001] This invention relates to the field of composite flooring, and more particularly to a processing equipment for wood-plastic composite flooring. Background Technology

[0002] Wood-plastic composite flooring is a new type of environmentally friendly floor decoration material made from wood fibers (such as wood chips and bamboo powder), thermoplastic plastics (such as PE, PP, and PVC), and additives through high-temperature melting and extrusion molding processes. It combines the natural texture of wood with the physical properties of plastic: it maintains the texture and beauty of wood products while overcoming the disadvantages of solid wood such as being susceptible to moisture, deformation, and insect infestation. At the same time, it is corrosion-resistant, wear-resistant, and recyclable. The product is commonly used in outdoor landscapes, balconies, and indoor homes, making it an ideal alternative to traditional solid wood and pure plastic flooring.

[0003] In the existing technology, during the preparation of wood-plastic composite flooring, the extruded wood-plastic composite flooring needs to be cooled down in a timely manner. However, the existing technology usually uses water cooling to cool the wood-plastic composite flooring. During the cooling process, the extruded wood-plastic composite flooring comes into contact with the cooling water, which may cause the cooling water to adhere to the wood-plastic composite flooring or seep into the interior of the wood-plastic composite flooring. This may result in the need for an additional drying step or water residue inside the wood-plastic composite flooring, thus affecting the storage quality of the wood-plastic composite flooring. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wood-plastic composite flooring processing device.

[0005] This invention provides a wood-plastic composite flooring processing device, comprising two first supports, and further comprising:

[0006] Two first motors are respectively fixed to the side walls of the two first brackets;

[0007] Two sets of first conveyor rollers, with two first conveyor rollers forming a set, and the first conveyor rollers in the same set being rotatably mounted on the same first bracket;

[0008] Two first conveyor belts are respectively driven and installed on two sets of first conveyor rollers, and the two first conveyor belts are used together to convey the wood-plastic composite flooring;

[0009] A cooling assembly, installed between the two first supports, is used to cool and reduce the temperature of the conveyed wood-plastic composite flooring;

[0010] The wrapping assembly, installed between the two first supports, is used to wrap the wood-plastic composite flooring during transportation and to wrap it under negative pressure during cooling to achieve water isolation.

[0011] During operation, the equipment is aligned with the end of the wood-plastic composite flooring extrusion equipment, allowing the extruded wood-plastic composite flooring to be directly conveyed. After the first motor starts, it drives the first conveyor roller connected to it to rotate via the output shaft. The rotation of the first conveyor roller drives the first conveyor belt, which in turn conveys the extruded wood-plastic composite flooring. The flooring is then conveyed through the wrapping component and the cooling component. As the flooring passes through the wrapping component, the component applies negative pressure to the outer surface of the flooring, isolating it from the cooling water during the cooling process. This helps prevent the cooling water from directly contacting the flooring and seeping into its interior, thus affecting its storage quality. The cooling component cools the extruded wood-plastic composite flooring, creating a temperature gradient during the cooling process. The higher-temperature cooling water first cools the flooring, and then the temperature gradually decreases. This helps prevent the flooring from directly contacting the flooring with supercooled water, which could cause internal stress and affect the extrusion quality, thus improving the processing quality of the wood-plastic composite flooring.

[0012] Preferably, the package assembly includes:

[0013] Two second brackets are fixed to the opposite sides of the two first brackets, respectively;

[0014] Two winding rollers are rotatably mounted on two second supports, respectively. The two winding rollers are a take-up winding roller and an unwinding winding roller. A drive motor that drives the take-up winding roller to rotate is mounted on the second support.

[0015] The film is wound around the two winding rollers at both ends and wrapped around the middle of the wood-plastic composite flooring;

[0016] A negative pressure component, mounted on the first bracket and positioned near the unwinding roller, is used to expel the airflow inside the film before the film wraps the wood-plastic composite flooring to create a negative pressure wrapping tendency.

[0017] Two sets of extrusion rubber are fixed to the top of the two first supports respectively, and are used to extrude the film to bond with the wood-plastic composite flooring to form a wrapping;

[0018] A sealing assembly, mounted on top between the two first supports, is used to compress and convey the two edges of the wrapped film to form a conveying seal.

[0019] The two ends of the film are wound by winding rollers, causing the film in the middle to wrap the formed wood-plastic composite flooring. During the wrapping process, the film is folded before wrapping, and after folding, the film wraps the wood-plastic composite flooring. The airflow of the folded film is extracted by a negative pressure component, causing the film to adhere to the surface of the wood-plastic composite flooring under the negative pressure of the extracted airflow. Then, the extrusion rubber squeezes the film after the airflow is extracted, so that the film is completely adhered to the surface of the film. Then, the sealing component is used to seal the edges of the folded film to prevent airflow from seeping in. This helps to maintain the vacuum wrapping effect of the film on the wood-plastic composite flooring, and helps the cooling water to fully wrap the wood-plastic composite flooring for cooling and temperature reduction.

[0024] After the negative pressure pump is started, the air between the folded films is extracted through the first delivery pipe, thereby creating a negative pressure between the folded films. Under the action of negative pressure, the film wraps and adheres to the wood-plastic composite flooring, which helps to improve the film's wrapping and adhesion to the wood-plastic composite flooring.

[0073] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0074] like Figures 1 to 7 The illustrated wood-plastic composite flooring processing equipment includes two first supports 1, and further includes:

[0075] Two first motors 101 are respectively fixed to the side walls of two first brackets 1;

[0076] Two sets of first conveyor rollers 102, two first conveyor rollers 102 form a group, and the first conveyor rollers 102 in the same group are rotatably mounted on the same first bracket 1;

[0077] Two first conveyor belts 103 are respectively driven and installed on two sets of first conveyor rollers 102, and the two first conveyor belts 103 are used together to convey the wood-plastic composite flooring;

[0078] A cooling assembly, installed between the two first supports 1, is used to cool and reduce the temperature of the conveyed wood-plastic composite flooring;

[0079] The wrapping assembly, installed between the two first supports 1, is used to wrap the wood-plastic composite flooring during the conveying process and to wrap it under negative pressure during the cooling process of the wood-plastic composite flooring to achieve water isolation.

[0080] In the existing technology, during the preparation of wood-plastic composite flooring, the extruded wood-plastic composite flooring needs to be cooled down in a timely manner. However, the existing technology usually uses water cooling to cool the wood-plastic composite flooring. During the cooling process, the extruded wood-plastic composite flooring comes into contact with the cooling water, which may cause the cooling water to adhere to the wood-plastic composite flooring or seep into the interior of the wood-plastic composite flooring. This may result in the need for an additional drying step or water residue inside the wood-plastic composite flooring, thus affecting the storage quality of the wood-plastic composite flooring.

[0081] This embodiment of the invention can solve the above problems. The specific implementation is as follows: During operation, the equipment is aligned with the end of the wood-plastic composite flooring extrusion equipment, so that the extruded wood-plastic composite flooring is directly conveyed. After the first motor 101 starts, it drives the first conveyor roller 102 connected to it to rotate through the output shaft. The rotation of the first conveyor roller 102 drives the first conveyor belt 103. The first conveyor belt 103, after transmission, conveys the extruded wood-plastic composite flooring, thereby allowing the wood-plastic composite flooring to be conveyed through the wrapping component and the cooling component. When the wood-plastic composite flooring passes through the wrapping component, the wrapping component applies negative pressure to the outer surface of the wood-plastic composite flooring, thereby allowing the wood-plastic composite flooring to cool. The composite flooring is isolated from the cooling water during the cooling process, which helps to prevent the cooling water from directly contacting the wood-plastic composite flooring and thus avoiding the possibility of cooling water seeping into the interior of the wood-plastic composite flooring and affecting its storage quality. The cooling component can cool down the wood-plastic composite flooring after extrusion molding, and there is a temperature gradient in the cooling process. This allows the higher temperature cooling water to cool the wood-plastic composite flooring first, and then the temperature gradually decreases. This helps to avoid the possibility of internal stress in the wood-plastic composite flooring caused by direct contact between the cooling water and the wood-plastic composite flooring, which would affect its extrusion quality. This helps to improve the processing quality of the wood-plastic composite flooring.

[0082] As an optional embodiment, the package component includes:

[0083] Two second brackets 201 are fixed to the opposite sides of the two first brackets 1 respectively;

[0084] Two winding rollers 202 are rotatably mounted on two second supports 201 respectively. The two winding rollers 202 are a winding roller and an unwinding roller respectively. A drive motor for driving the winding roller to rotate is mounted on the second support 201.

[0085] Film 2 is wound around two winding rollers 202 at both ends and wrapped around the middle of the wood-plastic composite flooring;

[0086] The negative pressure component, installed on the first support 1 and located near the unwinding and winding roller, is used to discharge the airflow inside the film 2 before the film 2 wraps the wood-plastic composite flooring to form a negative pressure wrapping tendency.

[0087] Two sets of extrusion rubber 203 are fixed to the top of the two first supports 1 respectively, and are used to extrude the film 2 to bond with the wood-plastic composite floor to form a wrapping;

[0088] A sealing assembly, mounted on top between two first supports 1, is used to squeeze and convey the two edges of the wrapped film 2 to form a conveying seal.

[0089] The two ends of the film 2 are wound by the winding rollers 202 at both ends, so that the middle film 2 wraps the molded wood-plastic composite floor. During the wrapping process, the film 2 is folded before wrapping. After folding, the film 2 wraps the wood-plastic composite floor, and the airflow of the folded film 2 is extracted by the negative pressure component, so that the film 2 adheres to the surface of the wood-plastic composite floor under the negative pressure of the extracted airflow. Then, the extrusion rubber 203 squeezes the film 2 after the airflow is extracted, so that the film 2 is completely adhered to the surface of the film 2 after being squeezed. Then, the sealing component is used to seal the edges of the folded film 2 to prevent the airflow from seeping in. This helps to maintain the vacuum wrapping effect of the film 2 on the wood-plastic composite floor, and helps the cooling water to fully wrap the wood-plastic composite floor for cooling and cooling.

[0090] As an optional embodiment, the negative pressure component includes:

[0091] The third bracket 301 is fixed at the top between the two first brackets 1;

[0092] The negative pressure pump 3 is fixed to the top of the third bracket 301, and the negative pressure pump 3 is located at one end near the unwinding and winding roller;

[0093] The first delivery pipe 302 is connected at one end to the input end of the negative pressure pump 3, and at the other end it extends through the third support 301 to the overlapping position of the film 2.

[0094] After the negative pressure pump 3 is started, the air between the stacked films 2 is extracted through the first delivery pipe 302, thereby creating a negative pressure between the stacked films 2. Under the action of negative pressure, the films 2 wrap and adhere to the wood-plastic composite flooring, which helps to improve the wrapping and adhesion of the films 2 to the wood-plastic composite flooring.

[0095] As an optional embodiment, the sealing assembly includes:

[0096] The fourth bracket 4 is fixed to the top of the third bracket 301;

[0097] The second motor 401 is fixed to the top of the fourth bracket 4;

[0098] Two sets of second conveying rollers 403, multiple second conveying rollers 403 as a group, the two sets of second conveying rollers 403 are symmetrically arranged, and both are rotatably installed on the bottom of the third bracket 301;

[0099] Two second conveyor belts 402 are respectively driven and installed on two sets of second conveyor rollers 403. The two second conveyor belts 402 respectively extrude the two sides of the film 2 after it is stacked.

[0100] Gear sets are installed at the ends of each of the second conveying rollers 403 and are used to drive the second conveying rollers 403 to rotate synchronously through gear transmission;

[0101] After the second motor 401 starts, it drives the second conveyor roller 403 to rotate through the output shaft. After the second conveyor roller 403 rotates, it drives all the second conveyor rollers 403 to rotate through the gear set. After the second conveyor roller 403 rotates, it drives the second conveyor belt 402. The two second conveyor belts 402 squeeze and seal the edges of the stacked film 2, and drive the edges of the film 2 during the squeezing and sealing process, thereby realizing the sealing and wrapping process of the film 2 on the wood-plastic composite floor and realizing the dynamic sealing and cooling process.

[0102] As an optional embodiment, the cooling assembly includes:

[0103] Cooling box 5 is fixed to the bottom of the third bracket 301;

[0104] Multiple partitions 501 are fixed in a linear array inside the cooling box 5 to divide the interior of the cooling box 5 into multiple cooling spaces with different temperatures;

[0105] Multiple sets of third conveyor rollers 502, with two third conveyor rollers 502 forming a group, and each group of third conveyor rollers 502 being rotatably installed inside each cooling space;

[0106] Multiple third conveyor belts 503 are respectively driven and installed on each third conveyor roller 502;

[0107] Multiple third motors 504 are fixed to the outside of the cooling box 5, and are used to drive one of the third conveyor rollers 502 in each group to rotate.

[0108] The cascading water flow assembly, installed inside the cooling tank 5, is used to drive the water flow in a stepped manner to gradually cool the wood-plastic composite flooring.

[0109] Two first scraping openings 505 are opened at both ends of the cooling box 5, and rubber material is used to scrape the surface of the thin film 2 that it passes through;

[0110] The cooling tank 5 can store cooling water. The cooling water temperature in the multiple cooling spaces is set in a gradient. After the third motor 504 starts, it drives the third conveyor roller 502 connected to it to rotate through the output shaft. The third conveyor roller 502 drives the third conveyor belt 503 to transport the wood-plastic composite flooring during the cooling process. The cascading component drives the cooling water to flow along the cooling space, thereby cooling the transported wood-plastic composite flooring. After the wood-plastic composite flooring is transported through the cooling tank 5, the water stains on the surface of the film 2 are scraped off by the first scraping opening 505, thereby reducing the water residue on the film 2 and facilitating the recycling of the film 2.

[0111] As an optional embodiment, the ladder flow component includes:

[0112] Multiple water pumps 6 are fixed inside each cooling space;

[0113] Multiple second delivery pipes 601 are respectively connected to the output end of water pump 6;

[0114] Multiple sets of nozzles 603 are installed inside each cooling space and face the passing wood-plastic composite flooring;

[0115] The input pipe 602 is fixedly connected to the side wall of the cooling box 5, with one end connected to the nozzle 603 closest to the winding roller and the other end connected to the external cooling water.

[0116] The output pipe 604 is fixedly connected to the side wall of the cooling box 5, with one end connected to the second conveying pipe 601 closest to the unwinding and winding roller, and the other end connected to the external recovery water tank.

[0117] Multiple connecting pipes 605 are used to connect adjacent second delivery pipes 601 and nozzles 603 respectively;

[0118] The inlet pipe 602 connects to the external cooling water supply, delivering the coolest water to the nozzles 603 inside the outermost cooling space to cool the wood-plastic composite flooring that is about to pass through the cooling box 5. Subsequently, the water pump 6 delivers water along the second delivery pipe 601 and the connecting pipe 605 to the nozzles 603 inside the adjacent cooling space, so that the water sprayed out by the nozzles 603 cools the wood-plastic composite flooring. This process is repeated to form a temperature gradient water flow that gradually cools the wood-plastic composite flooring until it reaches the outermost cooling space. The water pump 6 then delivers the water through the second delivery pipe 601 and the outlet pipe 604 before discharging it, completing the water flow.

[0119] As an optional embodiment, the cooling assembly further includes:

[0120] The extravasation recovery tank 7 is fixedly sleeved on the outside of the cooling tank 5;

[0121] Two second scraping openings 701 are opened at both ends of the cooling box 5, and rubber material is used to scrape the surface of the thin film 2 that passes through;

[0122] At the point where the film 2 and the wood-plastic composite floor pass through, the presence of the first scraping opening 505 causes water to seep out of the cooling tank 5 along the first scraping opening 505. By setting up the seepage recovery tank 7, the seepaged water will enter the interior of the seepage recovery tank 7 for recovery, thereby helping to prevent the leakage of cooling water from affecting the operation of the equipment. The second scraping opening 701 can scrape the edge of the film 2 again, thereby further scraping away the residual cooling water and reducing the recovery of water on the surface of the film 2.

[0123] As an optional embodiment, the package component further includes:

[0124] The sliding groove 8 is formed on the inner wall of the second support 201, and the sliding groove 8 and the unwinding and winding roller are located on the same second support 201;

[0125] The spare roller 801 is placed on the sliding groove 8;

[0126] Two first sliding plates 802 are fixed to both ends of the spare roller 801 and slidably mounted on the second bracket 201;

[0127] Two first cylinders 803 are fixed on the two side walls of the first bracket 1, and drive the two first sliding plates 802 to slide through the telescopic rod;

[0128] The friction pad groove is opened at the end of the sliding groove 8, and the edge is provided with a friction pad. When the spare roller 801 or the unwinding and winding roller moves to the position of the friction pad, it is positioned under the action of the friction pad and maintains normal rotation inside the friction pad groove.

[0129] Connectors are installed at the ends of the membrane 2 and are disposed on different surfaces of the membrane 2;

[0130] When the film 2 on the unwinding and winding roller is used up, the first cylinder 803 is started. The first cylinder 803 drives the first sliding plate 802 to move, and the first sliding plate 802 drives the spare roller 801 to move, so that the spare roller 801 moves along the sliding groove 8 to the position of the unwinding and winding roller for replacement, thereby realizing the replacement of the unwinding and winding roller. Furthermore, the film 2 can be connected through the connector provided at the end of the film 2, thereby realizing the sealed connection of the film 2 to continuously seal, wrap and cool the wood-plastic composite floor.

[0131] As an optional embodiment, the package component further includes:

[0132] Two second sliding plates 901 are symmetrically slidably mounted on the top of the second bracket 201, and the second sliding plates 901 and the unwinding and winding roller are located on the same second bracket 201;

[0133] Guide roller 9 is rotatably mounted between two second sliding plates 901, and an electrostatic film is installed on the outer wall of guide roller 9;

[0134] Two second cylinders 902 are installed on the side wall of the second bracket 201, and drive the second sliding plate 901 to move through the telescopic rod;

[0135] The guide roller 9 guides the end of the film 2 on the spare roller 801, and the electrostatic film allows the end of the film 2 on the spare roller 801 to be adsorbed. During the replacement process, the second cylinder 902 is activated. The second cylinder 902 drives the second sliding plate 901 to move through the telescopic rod. The second sliding plate 901 drives the guide roller 9 to move. After the guide roller 9 moves, it causes the end of the film 2 on the spare roller 801 to squeeze the unwinding and winding roller, so that the two are connected by the connector, which facilitates the automatic replacement of the unwinding and winding roller.

[0136] As an optional embodiment, the connector includes:

[0137] Two sets of hook and loop fasteners 10, two hook and loop fasteners 10 as a set, are respectively fixed to different sides of the end of the film 2;

[0138] Two sets of rubber pads 1001, multiple rubber pads 1001 are grouped together, and the rubber pads 1001 in the same group are arranged linearly. The rubber pads 1001 are fixed to the side wall of the film 2 and are respectively located between the two Velcro 10s in each group.

[0139] The Velcro 10 allows the ends of the films 2 to connect under slight pressure when they come into contact with the ends of the other films 2. After the connection is completed, the connection is achieved by the staggered compression of the two sets of rubber pads 1001, thereby sealing the connection end of the films 2. Subsequently, the sealing connection is achieved under the compression of the extrusion rubber 203, so as to improve the connection sealing effect after the replacement of the films 2.

[0140] Working principle of this invention: During operation, the equipment is aligned with the end of the wood-plastic composite flooring extrusion equipment, allowing the extruded wood-plastic composite flooring to be directly conveyed. After the first motor 101 starts, it drives the first conveyor roller 102 connected to it to rotate via the output shaft. The rotation of the first conveyor roller 102 drives the first conveyor belt 103, which in turn conveys the extruded wood-plastic composite flooring. The wood-plastic composite flooring is then conveyed through the wrapping component and the cooling component. When the wood-plastic composite flooring passes through the wrapping component, the wrapping component applies negative pressure to the outer surface of the wood-plastic composite flooring, thereby cooling the flooring during the cooling process. The cooling system is isolated from the cooling water, which helps prevent the cooling water from directly contacting the wood-plastic composite flooring and thus avoiding the possibility of cooling water seeping into the interior of the flooring and affecting its storage quality. The cooling component can cool down the wood-plastic composite flooring after extrusion molding, and there is a temperature gradient during the cooling process. This allows the higher temperature cooling water to cool the wood-plastic composite flooring first, and then the temperature gradually decreases. This helps to avoid the situation where the wood-plastic composite flooring is directly cooled by contact with supercooled water, which could cause internal stress in the flooring and affect its extrusion quality. This helps to improve the processing quality of the wood-plastic composite flooring.
