Description

TECHNICAL FIELD

[0001] The present application relates to a wood board production process, in particular to a wood board production process based on camphor wood waste. BACKGROUND

[0002] The edge strip waste left over in the processing of camphor wood logs, and the road pruning branches produced after the pruning of camphor wood street trees, etc. Forest three remaining things, due to the existence of different shapes and sizes, poor quality of wood defects, so that manufacturers of such waste treatment method is to uniformly process the waste into sawdust, and then through the plate making machine to hot-press the sawdust to form the shaving board, so as to realize the effective utilization of the forest three remaining things. And because the sources of different wood waste are different, and some waste will be affected by rainwater and soaked during transportation and accumulation, resulting in a large difference in the moisture content of different waste, so that the sawdust needs to be stationary and the moisture content needs to be adjusted after the sawdust is processed, so as to improve the processing effect of the subsequent process.

[0003] The conventional way of resting the sawdust is to mix the sawdust and the drying agent, and then stack them uniformly in an open factory building. In order to improve the utilization rate of indoor space and facilitate the stacking and subsequent handling of the sawdust, the sawdust will be scattered and stacked in different positions of the factory building in a fixed dumping manner, and the different sawdust piles will be tightly attached to each other to completely cover the ground of the factory building, leaving only a passageway for passing. But because the stacking points of the sawdust are densely distributed in different areas of the factory building, and occupy the ground space of the factory building as much as possible, the conventional continuous conveying mechanism cannot be used for conveying and stacking the sawdust. Under the above restrictions, the manufacturer can only rely on a dump truck to send the sawdust in batches to the designated stacking point and dump it, which on the one hand greatly reduces the dumping efficiency of the sawdust and increases the conveying cost, and on the other hand, the dumping process and the subsequent extraction and handling process cannot be carried out simultaneously, that is, the overall processing time of the wood board is prolonged.

[0004] In addition, since the temperature of the wood board after hot pressing can reach above 160℃, it is necessary to cool the wood board through a cooling device. The conventional turning plate type wood board cooling device is shown in patent 202211093121.6, which is set in staggered position with the conveying roller, so that after the wood board is conveyed to the position by the conveying roller, the wood board on the conveying roller can be lifted and rotated slowly by the turning plate machine, so that the wood board can be cooled during rotation and placed on the conveying roller on the other side after cooling, thereby realizing the cooling process of the wood board on line. However, the defect of this structure is that the wood board needs to be moved to the turning plate position in sequence at a constant conveying pace after hot pressing, so as to avoid collision between the wood board and the turning plate frame during movement. However, since the hot press machine realizes simultaneous hot pressing of multiple wood boards at a time, and there is a certain time interval between two hot pressing processes, it cannot guarantee that the wood board is placed on the conveying roller at an accurate working pace and a specified interval distance under the condition of continuous conveying of the conveying roller, thereby causing the conveying roller and the turning plate machine to be unable to coordinate with each other to realize the connection conveying and turning plate operation of the wood board. Therefore, the manufacturer currently needs to assist in feeding the wood board to ensure the stability of the conveying and turning plate of the wood board.

[0005] This feeding method mainly sets a photoelectric sensor on one side of the turning plate frame, which sends out an alarm after sensing when the turning plate frame rotates to a specified angle. At this time, the operator judges the current position of the wood board. If the wood board has been conveyed to the position partially overlapping with the turning plate frame at this time, it means that the wood board can be conveyed to the position within the remaining time, and the conveying roller continues to move. If the wood board has not moved to the overlapping position at this time, it means that there is a risk if the wood board continues to be conveyed, and the conveying roller stops moving. If the wood board is far away from the turning plate frame at this time, the conveying roller continues to convey, thereby ensuring the rapid positioning of the subsequent wood board. However, the above method has high labor cost and the risk of operation error, which is difficult to meet the pursuit of production stability and economy of the manufacturer.

[0006] Therefore, the existing wood board processing technology based on camphor wood waste has the problems of low wood chip conveying efficiency and poor turning plate stability. SUMMARY

[0022] When the position detection sensor is not triggered, the detection sensor detects the wood plate, and the angle detection assembly is triggered, the in-plate roller continues to convey until the position detection sensor is triggered.

[0023] When the position detection sensor is not triggered, the detection sensor does not detect the wood plate, and the angle detection assembly is triggered, the in-plate roller continues to convey until the detection sensor or the position detection sensor detects the wood plate.

[0029] (2) On the basis of the above, the structure of the material distribution conveying mechanism is limited, so that after any belt conveyor conveys wood chips to the end, it can choose to drop directly or pass to any adjacent belt conveyor, and the next belt conveyor conveys wood chips to other stationary points, thereby effectively improving the flexibility of the belt conveyor when arranging and avoiding the mutual intersection of belt conveyors in different conveying paths; and under the above cooperation, the material distribution conveying mechanism can be installed on the roof of the factory building, and the dropping position of each belt conveyor can completely cover different areas of the factory building, that is, the continuous conveying of wood chips at different stationary points is realized;

[0046] ③The B product is sequentially subjected to cooking, grinding and drying to form a wood chip blank with a specified moisture content to obtain C product;

[0047] ④The C product is sequentially subjected to material laying, pre-pressing thickness setting and hot-pressing plate making, so that the C product forms a long strip-shaped wood board with a specified thickness after processing to obtain D product;

[0048] ⑤The D product is cooled by a cooling machine to obtain E product;

[0049] ⑥ The E product is cut into several small wood board blanks of the same size by a sawing machine and cured for more than 72 hours. Then, the excess material on the edges of each wood board blank is removed by an edge sawing machine to obtain the finished wood board.

[0050] In step ②, multiple belt conveyors transport product A, and the different belt conveyors, when combined, form different conveying paths, thereby allowing product A to be transported along different conveying paths to different resting points; Figure 3 For example, Figure 3 The sawdust is transported by eight belt conveyors, which are combined to form nine conveying paths, and the sawdust is transported to nine resting points in sequence.

The material conveying mechanism is configured as follows: Figure 1 As shown, the structure includes a fixed frame 1 located on the top of the factory building, with the upper end of the fixed frame 1 connected to the steel beams of the factory building roof. Multiple belt conveyors 2 are connected to the bottom of the fixed frame 1. The length and orientation of the belt conveyors 2 can be freely set according to their stationary positions. Each belt conveyor 2 is inclined upwards along the conveying direction. Different belt conveyors 2, when connected sequentially, form conveyor line groups with different conveying paths. Adjacent belt conveyors 2 within the same conveyor line group are spaced apart end-to-end to form a discharge port 3. A steering assembly is connected to the end of each belt conveyor 2. The steering assembly includes a feeding plate 4 rotatably connected to the lower end of the belt conveyor 2. A driving component 5 is connected to one side of the feeding plate 4.

The drive motor and the feeding plate 4 are interconnected via a worm gear transmission structure. One end of the feeding plate 4 forms an inclined downward feeding surface, and the end of the feeding surface extends to the inside of the belt conveyor 2 or above another belt conveyor 2.

[0052] The width of the feeding surface gradually decreases along the conveying direction, and vertical guardrails 6 are formed on both sides of the feeding surface.

[0053] The top of the feeding plate 4 is provided with a support cylinder 401, the inner side of the support cylinder 401 is rotationally connected with a support shaft 402, the upper end of the support shaft 402 is detachably connected with the belt conveyor 2, the top of the support cylinder 401 is connected with the driving member 5 through a worm gear transmission structure, and the feeding plate 4 is located below the driving member 5 along the height direction; the lower end of the support shaft 402 penetrates through the feeding plate 4 and is detachably connected with a support part, so that the feeding plate 4 is supported through the cooperation of the support part and the support shaft 402; the feeding plate 4 can rotate 360° around the support shaft 402 under the driving action of the driving member 5, when the feeding plate 4 rotates to the inner side of the belt conveyor 2, the feeding plate 4 and the discharging opening 3 are in a mutually staggered state, at this time, the wood chips on the belt conveyor 2 can directly fall to the lower side along the discharging opening 3, and will not contact the feeding plate 4, that is, the direct discharging of the belt conveyor 2 at the discharging opening 3 is realized.

[0054] The number of adjacent belt conveyors 2 connected with each belt conveyor 2 is preferably one or two, and the support shaft 402 can be eccentrically arranged on the belt conveyor 2 as needed, so that the feeding plate 4 can completely cover the discharging opening 3 after rotating to face another belt conveyor 2.

[0056] One end of the in-plate roller 10 is provided with a to-position sensor 13 for detecting whether the wood board is conveyed to position, the middle part of the in-plate roller 10 is provided with an angle detection assembly for detecting the rotating position of the plate turning rack 12, the angle detection assembly is provided with a detection sensor 14 for detecting the conveying position of the wood board on the side away from the to-position sensor 13, and the detection sensor 14 is located on the outer side of the plate turning rack 12, when the wood board moves to trigger the detection sensor 14, the wood board and the plate turning rack 12 are in a front-rear staggered non-interference state;

[0057] When the to-position sensor 13 detects that the wood board is conveyed to position, the in-plate roller 10 stops conveying;

[0058] When the wood board is detected by the detection sensor 14 and the angle detection assembly is triggered, the feeding roller 10 continues to convey until the wood board is detected by the detection sensor 14 or the in-place sensor 13;

[0059] When the wood board is not detected by the detection sensor 14 and the angle detection assembly is triggered, the feeding roller 10 continues to convey until the wood board is detected by the detection sensor 14 or the in-place sensor 13;

[0060] When the in-place sensor 13 and the angle detection assembly are not triggered, the feeding roller 10 keeps conveying;

[0061] Wherein the priority of the in-place sensor 13 is higher than that of the angle detection assembly and the detection sensor 14.

[0062] The angle detection assembly comprises a mounting pin 15 connected to one side of the feeding roller 10, the outer part of the mounting pin 15 is rotationally connected with a V-shaped frame, the two sides of the V-shaped frame are respectively formed with a triggering plate 16 and a contact plate 17; one end of the triggering plate 16 is provided with a circular-arc-shaped baffle 18, one side of the baffle 18 is provided with a triggering switch 19 connected with the feeding roller 10, the angle detection assembly is triggered when the triggering switch 19 detects the baffle 18, and one side of the triggering plate 16 is mutually attached with a limiting block 20 connected with the feeding roller 10.

[0063] The V-shaped frame comprises a sleeve 21, the triggering plate 16 and the contact plate 17 are respectively rotationally connected with the sleeve 21, the end part of the sleeve 21 penetrates through the triggering plate 16 and the contact plate 17 and is threadedly connected with a round nut; one end of the contact plate 17 is slidingly connected with an elongated counterweight 22, the counterweight 22 and the contact plate 17 are fixed with each other through a set screw, and the counterweight 22 partially overlaps the flap frame 12 in the horizontal direction.

[0064] The in-place sensor can be selected as a micro switch, and the detection sensor and the triggering switch can be selected as photoelectric sensors.

[0065] The working principle of the present application is as follows: when the wood chips are conveyed, the feeding plate 4 on the belt conveyor 2 is first driven to rotate, so that the belt conveyors 2 on each conveying path are connected end to end, thereby conveying the wood chips to the end position of the conveying path and making them fall from the tail end of the dropping port 3 to the factory floor, realizing the stacking of the wood chips at the static point. After the wood chips are stacked at a static point, the feeding plate 4 on the belt conveyor 2 continues to rotate to form another conveying path, and then the wood chips are conveyed to another static point in the same way and stacked. Under the above cooperation, the manufacturer can sequentially stack the wood chips at each static point, effectively reducing the number of belt conveyors 2 required for conveying, and avoiding the occupation of the factory floor, thereby improving the space utilization.

[0066] When the wood chips are processed by the board forming machine to form the wood board blank, the wood board blank is moved by the feeding roller 10 towards the roller 7. When the wood board blank moves to the triggering detection sensor 14, the cooling machine can determine based on the triggering of the angle detection assembly. If the angle detection assembly is triggered at this time, it means that the wood board blank continues to move and there is a risk of directly colliding with the board turning frame 12. Therefore, the feeding roller 10 stops conveying until the risk is eliminated. If the angle detection assembly is not triggered at this time, it means that the wood board blank can be moved in place before the board turning frame 12 contacts the wood board blank. Therefore, the feeding roller 10 can act synchronously with the roller 7 and drive the wood board blank to move in place before contacting the board turning frame 12, thereby ensuring the stability of the wood board blank turning of the cooling machine and maximizing the feeding efficiency of the feeding roller 10. The accumulation of wood board blanks on the feeding roller 10 is alleviated. On the other hand, due to the above cooperation, the roller 7 can keep rotating at a constant speed, so that the wood board blank can be placed on the intermediate roller 9 at the same frequency in the subsequent conveying process. Therefore, the intermediate roller 9 and the roller 7 can cooperate with each other in a continuous working state, so as to ensure the stable entry of the wood board blank into the second roller 7.

[0067] When the manufacturer installs the angle detection assembly, the triggering position and the separation position of the board turning frame 12 can be adjusted by changing the horizontal position of the angle detection assembly and the extension length of the counterweight 22. Therefore, the triggering time of the triggering switch 19 can be adjusted through on-site testing, that is, the wood board blank will not collide with the board turning frame 12 under this control mode, and the stability of the wood board blank turning of the cooling machine is improved.
