Description

Technical Field

[0001] The present invention relates to the technical field of wood pellet floor production, and particularly to an automated production line for batch manufacturing of wood pellet reinforced composite floors. Background Art

[0002] The wood pellet reinforced composite floor is a new type of special board for railway flat cars researched by the Metal and Chemistry Research Institute of China Academy of Railway Sciences Corporation Limited (Patent Name: A Composite Wood Floor for Railway Flat Cars, Patent Application No.: 202121405576.8). This type of board can replace the existing wooden floors of railway flat cars, and its strength, nail-holding power, corrosion resistance, fire resistance, etc. are all superior to the existing wooden floors.

[0003] The treatment of the main raw material wood pellets of the wood pellet reinforced composite floor includes pre-drying, preservative spraying, and post-drying; the wood pellet reinforced composite floor is composed of three layers of materials, namely a reinforcement layer, a bearing layer, and an elastomer layer from bottom to top. The reinforcement layer is a metal composite material cut according to size. After sandblasting the surface to improve the friction, it is directly laid at the bottom of the mold; the bearing layer is a middle layer composed of a mixture of polyurethane foam material and wood pellets, which has the advantages of light weight, strong bearing capacity, and environmental friendliness; the elastic layer is the top layer made of elastic material, which is a wear-resistant layer for directly contacting the goods. The large surface friction coefficient helps to fix the goods, and its bottom surface is also sandblasted to increase the friction. The surfaces of the reinforcement layer and the elastomer in contact with the bearing layer are sandblasted respectively, so that the colloidal bearing layer can flow and penetrate into the rough surface, increasing the contact area to make the three-layer structure combine more tightly. The pressed floor needs to be processed such as edge cleaning and cutting to obtain the finished floor.

[0004] Since the wood pellet reinforced composite floor is a new type of board, its manufacturing technology and process are different from the processing methods of existing composite wood floors. How to achieve the batch automated production of wood pellet reinforced composite floors is a blank in the field. The laboratory has achieved the process from scratch, but there is no existing experience to refer to for the batch production from 1 to 100. The existing composite wood board production lines include processing devices such as bonding, cold pressing, cutting, and polishing, but mainly for the production of indoor composite wood floors; the structures and raw material treatments of the existing composite wood floors are different from those of the wood pellet reinforced composite floors that need to be mass-produced. The existing composite wood board production lines cannot fully adapt to the manufacturing process of wood pellet reinforced composite floors and cannot achieve the mass production of wood pellet reinforced composite floors. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the technical problem solved by the present invention is to provide an automated production line for batch manufacturing of wood particle-reinforced composite floors, so as to solve the problem that the existing composite wood board production line cannot fully adapt to the manufacturing process of wood particle-reinforced composite floors and cannot achieve mass production of wood particle-reinforced composite floors.

[0006] To solve the above problems, the technical solution adopted by the present invention is: an automated production line for batch manufacturing of wood particle-reinforced composite floors, including an anti-corrosion drying process, a pressing process, and a finished product processing process arranged in sequence;

[0007] The anti-corrosion drying process includes a first drying device for pre-drying wood particles, an anti-corrosion treatment device for uniformly mixing wood particles with preservatives, and a second drying device for drying the anti-corrosion wood particles containing preservatives, which are arranged in sequence;

[0008] The pressing process includes a mold, a ring conveyor line and a beam-type bearing structure for circulating and transporting the mold. The mold includes a bottom mold and an upper mold that can slide up and down along the bottom mold; the ring conveyor line includes a reinforcing layer laying section, and a stirring and feeding section, an elastomer spraying section, a mold closing section, a pressing and locking section, a heat preservation and curing section, and an unlocking and demolding section arranged in sequence along the floor manufacturing process; the beam-type bearing structure includes a manipulator bearing structure, and a reciprocating grabbing mechanism is installed on the manipulator bearing structure. The grabbing mechanism is used to combine the upper mold and the bottom mold in the mold closing section, and separate the upper mold and the bottom mold in the unlocking and demolding section; the stirring and feeding section includes a stirring and feeding device for uniformly mixing the anti-corrosion wood particles with additives and filling them into the mold; the elastomer spraying section includes an elastomer casting machine for uniformly spraying the surface of the wood particles in the mold; the pressing and locking section includes a pressure device for pressing the mold and a locking mechanism for locking the mold; the heat preservation and curing section includes a third drying device for drying the mold, and the unlocking and demolding section includes an unlocking device for unlocking the mold;

[0009] The finished product processing process includes a first edge cleaning machine for cleaning the rough edges of the floor and a cutting device for cutting the floor; it also includes multiple processing transmission lines, which are respectively arranged in sequence between the anti-corrosion drying process, the pressing process and the finished product processing process.

[0010] The beneficial effects of this solution are: 1. Realize the continuous and automated production of wood particle-reinforced composite floors from the anti-corrosion drying of wood particles to pressing and processing into finished products; 2. Achieve the mass production capacity of 30 daily production units of wood particle-reinforced composite floors, and successfully transform the laboratory research results into mass-produced products.

[0011] Further, the anti-corrosion treatment device includes a weighing mechanism for weighing wood particles and a spraying mechanism for spraying preservatives. Both the weighing mechanism and the spraying mechanism are electrically connected to a first controller. The weighing mechanism feeds back the weight data of the wood particles to the first controller, and the first controller adjusts the flow rate of the preservatives sprayed by the spraying mechanism in real time according to the received weight data of the wood particles. By controlling and adjusting the flow rate value of the spraying mechanism, the real-time matching of the weight data of the wood particles and the dosage of the preservatives per unit time is achieved; the wood particles and the preservatives can be fully mixed, and the wood particles can uniformly absorb the preservatives, ensuring the quality of the anti-corrosion treatment of the wood particles.

[0012] Further, the bottom mold is composed of a plate-shaped lower mold and a frame-shaped middle mold to form a box shape. The mold is designed into a three-layer structure that can be separated from each other, which facilitates the quick demolding of the pressed wood floor from the inside of the mold.

[0013] Further, the manipulator bearing structure includes a middle mold manipulator bearing structure and an upper mold manipulator bearing structure. Along the length of the middle mold manipulator bearing structure, there is a middle mold transmission line that can step-transport multiple middle molds. Along the length of the upper mold manipulator bearing structure, there is an upper mold transmission line that can step-transport multiple upper molds; an upper mold grasping mechanism that can reciprocate is installed on the upper mold manipulator bearing structure. The upper mold grasping mechanism is used to take out the upper mold from the middle mold or install the upper mold onto the middle mold. A middle mold grasping mechanism that can reciprocate is installed on the middle mold manipulator bearing structure. A plate ejecting mechanism is installed on the middle mold grasping mechanism. The middle mold grasping mechanism is used to take out the middle mold from the bottom mold or install the middle mold onto the bottom mold. The plate ejecting mechanism is used to eject the floor on the inner wall of the middle mold.

[0014] Since there is no existing experience to follow in the production of this wood particle reinforced composite floor, if manual operation is adopted, the molds are frequently lifted and transported, with extremely low efficiency and great potential quality and safety hazards. Through the circular conveyor line in cooperation with the middle mold manipulator bearing structure and the upper mold manipulator bearing structure, the demolding and mold closing of the upper mold and the middle mold are made one-to-one corresponding. The plate-shaped lower mold moves along with the circular conveyor line, realizing the automated batch production in the pressing process of the wood particle reinforced composite floor. The molds do not come off the line throughout the process and operate in a cycle.

[0015] Further, the finished product processing procedure further includes a floor sorting mechanism and a floor stacking mechanism that are sequentially arranged along the processing conveyor line after the cutting device. The floor sorting mechanism includes a weighing mechanism that is horizontal with the transmission surface of the processing conveyor line, and a pushing mechanism that is arranged above the weighing mechanism and is used to push out the boards with unqualified weights. Through the sorting mechanism, the automated screening of unqualified boards is realized, ensuring the quality of the floor finished products, without manual screening, which is convenient and fast.

[0016] Further, a floor shunting device is provided between the first edge trimming machine and the cutting device in the finished product processing process. A buffer transfer line is provided before the first edge trimming machine and the shunting device. The floor shunting device includes a reversing transfer table and a shunting transfer mechanism for shunting and transferring. The reversing transfer table includes a rotating table and a reversing lift arranged successively from top to bottom. The rotating table includes a turntable and a steering motor fixed under the turntable. A conveyor belt is arranged radially in the turntable, and the conveying surface of the conveyor belt is horizontal with the turntable plane. The reversing transfer table is used to transfer the floor to the shunting transfer mechanisms at different heights and positions.

[0017] Further, the finished product processing process further includes a cushion strip cutting process. The cushion strip cutting process includes a cutting transfer line, and a sawing machine for cutting the floor in the width direction, a multi-blade saw for cutting the floor in the thickness direction, and a push bench saw for cutting the floor in the length direction, which are arranged successively along the cutting transfer line. Through the cooperation of the cutting transfer line with the sawing machine, the multi-blade saw, and the push bench saw, the mass production and rapid processing of the wooden cushion strips are realized.

[0018] Further, both the first drying equipment and the second drying equipment adopt drum-type drying equipment. The drum-type drying equipment includes a drying cylinder that can be driven to roll by a driving mechanism and a heat source mechanism for providing heat to the drying cylinder. One end of the drying cylinder is provided with a feeding end, and the other end is provided with a discharging end. The heat generated by the heat source mechanism of the first drying equipment is directly fed into the drying cylinder from the feeding end of the drying cylinder; the heat generated by the heat source mechanism of the second drying equipment first heats the drying cylinder from the outside of the drying cylinder and then is fed into the drying cylinder from the feeding end of the drying cylinder. Avoiding the direct heating of the wood particles containing preservatives by the heat source mechanism makes the temperature in the drying cylinder of the second drying equipment not exceed 150 °C, preventing the preservatives from losing efficacy; the moisture content of the wood particle raw materials is reduced to 30% and below by the first drying equipment, and the moisture content of the preservative-treated wood particles is reduced to below 12% by the second drying equipment.

[0019] Further, a plurality of positioning mechanisms are arranged along the transmission direction of the annular conveyor line. The plurality of positioning mechanisms are respectively arranged in the stirring and feeding section, the mold closing section, the pressing and clamping section, and the unlocking and demolding section. The positioning mechanism includes movable positioning parts respectively arranged along the four sides of the mold. The centering and clamping of the mold are realized through the positioning parts, and the mold is positioned, which is convenient for the disassembly and combination of the mold.

[0020] Further, it further includes a reinforcing layer treatment process. The reinforcing layer treatment process includes a second edge trimming machine for trimming the edge of the reinforcing layer and a gluing machine for gluing the reinforcing layer, which are arranged successively. By configuring the reinforcing layer treatment process to batch-process the reinforcing layer, the pressing process of the floor is coordinated to ensure the orderly progress of the mass production of the floor.

When positioning is required, the front end limiting mechanism is used to restrict the mold from continuing to advance, and the position sensor is used to detect whether the mold is transported to the set position, so that the second controller controls the rear end limiting mechanism to limit the rear end of the mold, and finally the side positioning assembly positions the two sides of the mold; after the bottom mold and the upper mold are combined, the second controller controls the electric cylinders of each positioning assembly to retract, and then starts the transmission mechanism to transport the mold to the next process, so as to cooperate with the transmission mechanism to position and transfer the mold. When the position sensor detects that the current mold has completely left, the second controller controls the front end limiting mechanism to rise.

[0032] Reference Figure 2, the reinforcing layer laying section is located between the elastomer spraying section and the mold closing section. When the lower mold is transported to the reinforcing layer laying section, it is located below one end of the middle mold manipulator bearing mechanism. At this time, the circular transmission line stops, and the positioning mechanism positions the lower mold. The middle mold grasping mechanism grasps the middle mold and the lower mold to form a box-shaped bottom mold, and the reinforcing layer is placed in the bottom mold through the middle mold grasping mechanism. After the reinforcing layer is laid, the circular transmission line transports the bottom mold to the mixing and feeding section. The mixing and feeding device 210 mixes the wood particles and the polyurethane modified foaming material evenly through stirring. The bottom mold is transported to the lower part of the mixer, and the positioning mechanism positions the middle part. After the materials are stirred evenly, the mixer feeds the materials into the mold. After the materials are leveled, the mold flows to the elastomer spraying section through the circular transmission line. The mold is transported to the elastomer spraying section, and the circular transmission line at this section stops. An elastomer casting machine 220 evenly sprays a layer of elastomer on the surface of the wood particles. After spraying is completed, when there is no mold at the mold closing section, the circular transmission line at this station starts, and the mold is transported to the mold closing section. When the bottom mold is transported to the mold closing section, it is located below the upper mold mechanical bearing structure. The upper mold manipulator grasps the upper mold and places it in the bottom mold. The entire mold assembly is completed. The mold moves along the circular transmission line to the lower part of the press in the pressing and clamping section. The press presses down the upper mold, and the clamping mechanism clamps the mold in the clamped state. The mold moves along the circular transmission line to the third drying device in the heat preservation and curing section. After heat preservation for several hours, it moves along the circular transmission line to the unlocking and demolding section to unlock the mold. At this time, the upper, middle, and bottom molds of the mold are integrated but can be separated from each other. The mold moves along the circular transmission line to the lower part of the upper mold mechanical bearing structure. The upper mold manipulator grasps the upper mold and places the upper mold on the upper mold transmission line. During the movement of the upper mold on the upper mold transmission line, the upper mold is cleaned and sprayed with a release agent manually.

[0033] The mold with the upper mold removed is a box-shaped bottom mold. The bottom mold moves forward to the lower part of the middle mold mechanical bearing structure. The middle mold manipulator grasps the middle mold, and the manufactured wood floor is clamped in the middle mold. The plate ejecting mechanism on the middle mold manipulator ejects the floor. The middle mold manipulator then places the empty middle mold on the middle mold transmission line. During the transmission of the middle mold by the middle mold transmission line, the middle mold is cleaned and sprayed with a release agent manually. The lower mold moves alone along the circular transmission line. When it moves to the reinforcing layer laying section, it is located below the middle mold manipulator bearing structure 261. The middle mold grasping mechanism grasps the middle mold on the middle mold transmission line and places it on the lower mold, forming a box-shaped bottom mold again. The reinforcing layer is placed in the bottom mold through the middle mold grasping mechanism, and this process repeats in a cycle.

[0034] The processing transmission line further includes a finished product transmission line disposed within the finished product processing process 300. The finished product processing process 300 includes a first edge cleaning machine 310 for cleaning the floor rough edges, a cutting device 380 for cutting the floor, a floor sorting mechanism 320, a floor marking machine 330, and a floor palletizing mechanism 340, which are sequentially arranged along the transmission direction of the finished product transmission line. The floor sorting mechanism 320 includes a second controller, a weighing mechanism with a horizontal transmission surface of the processing transmission line, and a pushing mechanism disposed above the weighing mechanism for pushing out the floors with unqualified weights. The weighing mechanism is electrically connected to the input end of the second controller, and the pushing mechanism is electrically connected to the output end of the second controller. The controller is used to control the pushing mechanism to push out the floors that do not meet the set weight value from the finished product transmission line according to the weight data fed back by the weighing mechanism. The floor palletizing mechanism 340 selects a six-axis robot to pick up the floors from the finished product transmission line and stack them neatly according to the quantity for one vehicle. The pushing mechanism uses an electric cylinder, and the moving direction of the electric cylinder is perpendicular to the transmission direction of the finished product transmission line.

[0035] Embodiment 2 is as Figure 3 shown. The same parts as in Embodiment 1 will not be described again. The differences are that it further includes a reinforcing layer processing process, which includes a second edge cleaning machine 271 for cleaning the edges of the reinforcing layer and a gluing machine 272 for gluing the reinforcing layer, which are sequentially arranged, and a storage device for storing the glued reinforcing layer; the transfer between the reinforcing layer processing process and the reinforcing layer laying section is carried out by a transfer cart or a roller conveyor. In this embodiment, a roller conveyor is selected.

Multiple buffer transmission lines can be arranged between the first edge cleaning machine 310 and the diversion device.
