Description

Technical Field

[0001] This invention relates to the field of wood-plastic composite flooring production technology, and in particular to a wood-plastic composite flooring production equipment. Background Technology

[0002] With the widespread use of plastic products and wood materials, the disposal of plastic waste and agricultural and forestry waste has become a serious challenge in the field of environmental protection. Traditional landfill and incineration methods not only occupy land resources but also produce harmful gases, causing secondary pollution. Wood-plastic composites, as a new type of environmentally friendly building material, can utilize waste plastics and waste materials such as wood flour and straw powder, and have broad application prospects.

[0003] However, existing waste-recycling-based wood-plastic composite (WPC) flooring production equipment still has significant shortcomings in practical applications. First, different proportions of recycled materials require different mixing speeds, while traditional equipment typically uses a single drive component to uniformly change the mixing speed, making it difficult to differentiate based on material characteristics. This results in poor mixing uniformity and affects the product's mechanical properties. Second, in the preparation of multi-layer composite flooring, each layer needs to maintain a relatively independent state to achieve different functional properties. However, existing equipment struggles to flexibly switch between zone separation and independent mixing within the same mixing tank, limiting production efficiency and product diversity. Furthermore, when using a single-material formulation, it is difficult to create a performance gradient between the upper and lower layers of a single flooring unit, such as balancing surface wear resistance with bottom adhesion, resulting in insufficient product functional depth. Therefore, we propose a new WPC flooring production equipment. Summary of the Invention

[0006] Furthermore, the drive box is fixedly installed on the upper side of the base plate and the output end of the drive box is fixedly connected to the side of the threaded rod of the screw extruder. The heating modules are equidistantly arranged on the side of the screw extruder, and the die block is arranged on the side of the output end of the heating module. The die block is connected to the output ends of the three screw extruders through pipes.

[0007] Furthermore, the first and third stirring cylinders are mirror images of each other and are rotatably mounted on the upper and lower sides of the mixing tank, respectively. The second stirring cylinder is located inside the mixing tank, and the two sides of the third stirring cylinder are rotatably connected to the first and third stirring cylinders. Stirring rods are fixedly installed at equal intervals on the sides of the first, second, and third stirring cylinders.

[0008] Furthermore, the first gear ring and the second gear ring are fixedly installed on the inner side of the first stirring tank, the second stirring tank and the third stirring tank. The first mating wheel is equidistantly meshed on the inner side of the first gear ring, the first drive wheel is meshed on the side of the first mating wheel, the second mating wheel is equidistantly meshed on the inner side of the second gear ring, and the second drive wheel is meshed on the side of the second mating wheel.

[0009] Furthermore, the two ends of the constraint rod extend into the interior of the first and third mixing drums, and constraint frames are fixedly installed on both sides of the constraint rod, with the constraint frames fixedly installed on the upper and lower sides of the mixing drum.

[0010] Furthermore, the mating rod is disposed inside the first mixing drum, the second mixing drum, and the third mixing drum. The first electric push rod is fixedly disposed on the inner side of the mating rod corresponding to the positions of the first drive wheel and the second drive wheel. The locking block is fixedly disposed on the output end of the first electric push rod, and the locking block portion extends to the inner side of the first drive wheel and the second drive wheel. A motor is fixedly disposed on the upper side of the mating rod, and the motor is fixedly disposed on the upper side of the mixing drum via a cylindrical rod.

[0011] Furthermore, the fixing plate is fixedly installed on the inner side of the mixing tank and is movably sleeved on the side of the first mixing tank and the third mixing tank. The side of the fixing plate is provided with a first slot that penetrates it at equal intervals. The movable plate is movably sleeved on the side of the first mixing tank and the third mixing tank. The side of the movable plate is provided with a second slot that penetrates it at equal intervals.

[0012] Furthermore, the second electric push rod is fixedly installed inside the first and third mixing drums and is connected to the power supply module circuit via an electric wire. The deformable block is fixedly installed at the output end of the second electric push rod and corresponds to the position of the movable plate. The deformable block is a circular block made of wear-resistant rubber.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves independent speed control of different mixing drums under the same drive source by using a nested structure of the first, second, and third mixing drums in the drive mechanism, combined with a selectively driveable gear ring and mating wheel system. This allows operators to flexibly adjust the speed of each mixing drum according to the actual flow characteristics and proportioning requirements of the recycled plastic and wood powder mixture, thereby obtaining differentiated mixing effects and significantly improving the equipment's adaptability to various waste materials and the stability of product quality.

[0014] 2. This invention utilizes the cooperative structure of the fixed plate and the movable plate in the partition assembly, along with the second electric actuator driving the deformation block to rotate the movable plate. This allows the first slot and the second slot to switch between aligned and misaligned states, achieving the switching control of the separation and connection of the internal space of the mixing tank. When producing multi-layer composite flooring, the partition assembly can divide the mixing tank into multiple independent areas, allowing materials with different proportions to be mixed independently, avoiding mutual mixing, ensuring the independence and proportioning accuracy of each layer of functional materials, and providing a reliable guarantee for the preparation of composite flooring with different functional layers.

[0015] 3. This invention, through the different size design of the first and second gear rings, combined with the positioning and constraint structure of the first mating wheel, the second mating wheel, and the constraint rod, enables the first, second, and third mixing drums to obtain different rotational speeds under the same motor drive. Operators can control the rotation speed of the corresponding mixing drum according to the mixing requirements of each layer of material. For example, high-speed stirring is used for the lower layer of material to obtain a fine texture to improve the flatness of the laying, while low-speed stirring is used for the upper layer of material to maintain a rough texture to enhance surface wear resistance. Thus, under the condition of a single material formula, the gradient distribution of product performance is achieved in different areas by combining the partition components.

[0016] 4. The present invention achieves on-demand engagement of the transmission path by selectively embedding the battery module built into the first electric push rod drive block into the spline groove of the first drive wheel or the second drive wheel through the structure of the drive module built into the first electric push rod drive block. This allows the same drive source to selectively drive different stirring drums to rotate according to process requirements, which reduces the number of power equipment, lowers equipment manufacturing costs and energy consumption, simplifies the operation process, and makes speed switching in the production process more convenient and reliable.

[0017] 5. This invention uses three sets of screw extruders connected to three mixing cylinders, and uses a three-in-one die block for layered extrusion molding. The separately prepared materials are combined at the extrusion die to form a three-layer composite structure. The layers are naturally bonded together under high temperature and high pressure without the need for additional adhesives. This ensures the bonding strength between the layers and avoids the introduction of new chemical pollutants, reflecting the environmental protection concept of waste recycling.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figures 1 to 3As shown, a wood-plastic composite (WPC) flooring production equipment includes a base plate 1. Three sets of screw extruders 11 are equidistantly arranged on the upper side of the base plate 1. A drive box 12 is fixedly installed on the upper side of the base plate 1, corresponding to the screw extruders 11, with the output end of the drive box 12 fixedly connected to the side of the threaded rod of the screw extruder 11. The drive box 12 drives the threaded rod inside the screw extruder 11 to rotate, causing the screw extruder 11 to extrude and discharge the material. Heating modules 13 are equidistantly arranged on the side of the screw extruders 11. The heating module 13 consists of a hot air blower and a guide sleeve. The guide sleeve guides hot air to the side of the screw extruders 11 to continuously heat the material inside the screw extruders 11. A die block 14 is provided on the side of the output end of the heating module 13. The die block 14 is connected to the output end of the three sets of screw extruders 11 via pipes. The die block 14 is a three-part... In the first die head, a mixture of plastic and wood chips is continuously heated and flows into the die head block 14, forming a three-layer floor. The wood-plastic floor is then cooled and shaped in a cooling tank. A mixing tank 2 is fixedly installed on the upper side of the base plate 1, corresponding to the position of the screw extruder 11. Three sets of feed pipes 21 are fixedly installed at equal intervals on the side of the mixing tank 2, and the feed pipes 21 are connected to the feeding point, which can supply different materials. Three sets of discharge pipes 22 are fixedly installed at equal intervals on the side of the mixing tank 2, and the three sets of discharge pipes 22 pass through the screw extruder 11 to its interior. The discharge pipes 22 are round pipes with electrically controlled valves on the side. A drive mechanism 3 is set inside the mixing tank 2. The drive mechanism 3 can perform layered mixing of the supplied recycled plastic and wood chip mixture, and then discharge it to the corresponding screw extruder 11 through the discharge pipes 22.

[0022] like Figures 3 to 8As shown, the drive mechanism 3 includes a first stirring tank 31, a second stirring tank 32, and a third stirring tank 33. The first stirring tank 31 and the third stirring tank 33 are respectively mirror images of each other and rotatably mounted on the upper and lower sides of the stirring tank 2. The second stirring tank 32 is disposed inside the stirring tank 2, and the sides of the third stirring tank 33 are rotatably connected to the first stirring tank 31 and the third stirring tank 33. Stirring rods 311 are fixedly mounted at equal intervals on the sides of the first stirring tank 31, the second stirring tank 32, and the third stirring tank 33. The stirring rods 311 are rectangular rods. A first gear ring 34 and a second gear ring 35 are fixedly mounted on the inner sides of the first stirring tank 31, the second stirring tank 32, and the third stirring tank 33, respectively. The first gear ring 34 and the second gear ring 35 are circular ring blocks of different sizes with toothed inner sides. A first mating gear 341, which is a circular ring gear, is equidistantly meshed in a circumferential array on the inner side of the first gear ring 34. A first driving gear 342, which is a circular ring gear with spline grooves on its inner side, is meshed on the side of the first mating gear 341. A second mating gear 351, which is also a circular ring gear, is equidistantly meshed in a circumferential array on the inner side of the second gear ring 35. A second driving gear 352, which is also a circular ring gear with spline grooves on its inner side, is meshed on the side of the second mating gear 351. A constraint rod 36 is rotatably mounted inside a first mating wheel 341 and a second mating wheel 351, with both ends of the constraint rod 36 extending into the interior of the first mixing drum 31 and the third mixing drum 33. The constraint rod 36 is a round rod with continuous protrusions on its sides. A constraint frame 361 is fixedly mounted on both sides of the constraint rod 36, and the constraint frame 361 is fixedly mounted on the upper and lower sides of the mixing drum 2. A mating rod 37 is provided inside the first mixing drum 31, the second mixing drum 32, and the third mixing drum 33, and the first drive wheel 342 and the second drive wheel 352 are movably sleeved on the side of the mating rod 37. The mating rod 37 has a hollow structure and a built-in rechargeable battery module. A first electric actuator 371 is fixedly installed on the side corresponding to the positions of the first drive wheel 342 and the second drive wheel 352. The first electric actuator 371 is electrically connected to the cooperating rod 37. A locking block 372 is fixedly installed at the output end of the first electric actuator 371, and the locking block 372 extends to the inner side of the first drive wheel 342 and the second drive wheel 352. The locking block 372 is a circular block with teeth on one side. A motor 38 is fixedly installed on the upper side of the cooperating rod 37, and the motor 38 is fixedly installed on the upper side of the mixing tank 2 through a cylindrical rod. A partition component 4 is provided on the side of the first mixing tank 31 and the third mixing tank 33. The partition component 4 can divide the interior of the mixing tank 2.Specifically, the motor 38 can drive the mating rod 37 to rotate. The first electric push rod 371, by default, extends the locking block 372 portion to the inner side of the first drive wheel 342 and the second drive wheel 352, constraining either the first drive wheel 342 or the second drive wheel 352. Furthermore, the first electric push rod 371 pushes the locking block 372, causing its side toothed structure to engage with the spline groove inside the first drive wheel 342 or the second drive wheel 352, achieving a transmission connection. At this time, the rotation of the mating rod 37 drives the first drive wheel 342 or the second drive wheel 352 to rotate. The first drive wheel 342 or the second drive wheel 352 meshes with the corresponding first mating wheel 341 or the second mating wheel 351. Subsequently, the first mating wheel 341 or the second mating wheel 351 engages with the first gear ring. The first gear 34 or the second gear 35 engages again. Since the first gear 341 or the second gear 351 is fixed in position by the constraint rod 36, it only rotates on the side of the constraint rod 36. This allows the first gear 34 or the second gear 35 to drive the corresponding first mixing drum 31, second mixing drum 32, or third mixing drum 33 to rotate. This rotation drives the first drive wheel 342 or the second drive wheel 352, which in turn drives the corresponding first mixing drum 31, second mixing drum 32, or third mixing drum 33 to rotate synchronously at a torque speed. In this way, the stirring rods 311 on the sides of the first mixing drum 31, second mixing drum 32, or third mixing drum 33 can mix the material at different speeds.

[0023] like Figure 3 , Figure 4 and Figures 7 to 8As shown, the partition assembly 4 includes a fixing plate 41, which is fixedly installed inside the mixing tank 2 and movably sleeved on the sides of the first mixing drum 31 and the third mixing drum 33. The fixing plate 41 is an L-shaped annular plate. A first slot 411, which is fan-shaped, is equidistantly arranged in a circumferential array on the side of the fixing plate 41. A movable plate 42 is rotatably installed inside the fixing plate 41 and movably sleeved on the sides of the first mixing drum 31 and the third mixing drum 33. The movable plate 42 is an annular plate. A second slot 421, which is fan-shaped, is equidistantly arranged in a circumferential array on the side of the movable plate 42. The second slot 421 and the first slot 411 are staggered by default. A power supply module 43 is fixedly installed inside the first mixing drum 31 and the third mixing drum 33. The power supply module 43 is a... A charging annular battery block has a second electric push rod 44 fixedly installed through the inner side of the first stirring drum 31 and the third stirring drum 33. The second electric push rod 44 is connected to the power supply module 43 by a wire. A deformable block 45 is fixedly installed at the output end of the second electric push rod 44, and the deformable block 45 corresponds to the position of the movable plate 42. The deformable block 45 is a circular block made of wear-resistant rubber. Specifically, by default, the positions of the first slot 411 and the second slot 421 are staggered. At this time, the combination of the fixed plate 41 and the movable plate 42 can divide the interior of the bottom plate 1. Then, the second electric push rod 44 pushes the deformable block 45 to snap into place on the inner side of the movable plate 42. The first stirring drum 31 or the third stirring drum 33 is driven to rotate, which can drive the movable plate 42 to rotate synchronously inside the fixed plate 41, so that the second slot 421 corresponds to the first slot 411. At this time, the corresponding space inside the stirring drum 2 can be connected.

[0024] Working principle: In use: First, divide the area. Divide the production area according to the flooring production needs, such as a combination floor of three different materials or a single material floor. When producing single-layer material flooring, the second electric push rod 44 on the side of the first mixing drum 31 and the third mixing drum 33 pushes the deformation block 45 to snap and fit into the inner side of the corresponding movable plate 42. At this time, the first mixing drum 31 and the third mixing drum 33 are driven to rotate, causing the movable plate 42 to rotate inside the fixed plate 41. The rotation of the movable plate 42 makes the second slot 421 correspond to the first slot 411. At this time, the entire space inside the mixing drum 2 is connected, and the required plastic and wood chips can be directly conveyed through the feed pipe 21 for centralized processing. In the production of multi-layer material flooring, the movable plate 42 can be driven to rotate by the first mixing drum 31 and the third mixing drum 33, so that the second slot 421 and the first slot 411 are staggered. The internal space of the mixing drum 2 is divided by the fixed plate 41 and the movable plate 42. At this time, the corresponding feed pipe 21 can transport different materials into the mixing drum 2. For example, the upper material is made of a mixture of plastic and wood chips with glass fiber to improve wear resistance, the middle material is made of bio-based resin to enhance the anti-insect and moisture-proof effect, and the lower material is made of composite mineral particles to improve flame retardant performance. The second step involves adapting the material to the mixing chamber. After the material is fed into the mixing drum 2, the motor 38 drives the mating rod 37 to rotate. The first electric push rod 371, corresponding to the inner sides of the first mixing drum 31, second mixing drum 32, and third mixing drum 33, pushes the corresponding locking block 372 to engage with the inner side of the first drive wheel 342 or second drive wheel 352. This causes the corresponding first drive wheel 342 or second drive wheel 352 to rotate synchronously under the drive of the mating rod 37. The first drive wheel 342 or second drive wheel 352 meshes with the first mating wheel 341 or second mating wheel 351. Because the constraint rod 36 is fixed in position by the constraint frame 361, the first mating wheel 341 and the second mating wheel 351... 1. Restricted by the constraint rod 36, it can only rotate around its axis. The first gear ring 34 or the second gear ring 35 can be driven by the first drive wheel 342 or the second drive wheel 352 to change speed and torque. By rotating the first gear ring 34 or the second gear ring 35 to drive the first mixing drum 31, the second mixing drum 32 and the third mixing drum 33, the first mixing drum 31, the second mixing drum 32 and the third mixing drum 33 can achieve different rotational mixing speeds under the same drive source, so as to meet the mixing requirements of different materials. In the production of a single-layer material floor, the first mixing drum 31, the second mixing drum 32 and the third mixing drum 33 can also mix the same material at different speeds, so that the material consistency of the corresponding layers is different. The third step is the plastic production of the flooring. The material inside the mixing tank 2 is conveyed to the corresponding screw extruder 11 by the driving mechanism 3. Then, the screw extruder 11 is driven by the drive box 12 to extrude the material and convey it. The heating module 13 continuously heats the material. The material is conveyed from the three sets of screw extruders 11 and supplied in layers to the die block 14. After being constrained and shaped by the die block 14, the three layers of material from the three sets of screw extruders 11 can be combined and discharged in layers. After further pressing and shaping by the subsequent pressure rollers and cooling in the cooling pool, the shaping production of the wood-plastic flooring is completed. In the production of single-layer flooring, if the partition component 4 remains closed, the three mixing drums independently mix materials of the same formula. By setting different mixing speeds, materials with different degrees of mixing can be obtained. For example, a higher speed is used for the mixing drum corresponding to the lower structure to obtain a more uniform and finer material, thereby improving the flatness of the bottom of the flooring. A lower speed is used for the mixing drum corresponding to the upper structure to keep the material relatively rough, thereby enhancing the wear resistance of the flooring surface. Thus, even using a single material formula, the final molded wood-plastic composite flooring can exhibit a certain gradient layering effect in terms of performance.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
