Description

Technical Field

[0001] This utility model relates to the field of wood compaction machine transmission technology, specifically a wood compaction machine transmission device. Background Technology

[0002] Wood compaction is a technique that improves the properties of wood through physical methods. It mainly uses high temperature and high pressure to treat wood, which significantly improves its density, hardness and stability.

[0003] In the machinery industry for wood compaction, the processing steps mainly include wood heating, compaction, shaping, and conveying. Conventional compaction typically involves holding the wood under pressure for a period after compaction until it is fully shaped before conveying it. This process is time-consuming, inefficient, and increases the manufacturing cost of wood compaction machines. Therefore, to address these issues, a transmission device for a wood compaction machine is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, conventional compaction typically involves holding the wood under pressure for a period of time after compaction until it is fully formed before conveying it. This process is time-consuming, inefficient, and increases the production cost of wood compaction. This invention proposes a transmission device for a wood compaction machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The transmission device of the wood compaction machine of this utility model includes a hydraulic mechanism and a transmission mechanism. The hydraulic mechanism includes a press frame and an oil cylinder installed on the upper part of the press frame for providing compaction power. The transmission mechanism includes a lower driving roller set on the lower table of the press and an upper driven roller set on the upper table of the press for supporting and transporting wood. A servo motor drives the lower driving roller to rotate to realize the automated conveying of wood.

[0006] Preferably, the hydraulic mechanism further includes an oil tank installed on the top of the press frame and connected to the oil cylinder to continuously supply hydraulic oil, a heat insulation plate fixed to the lower part of the press frame and the lower platform of the press installed on the heat insulation plate, and the upper platform of the press connected to the oil cylinder and movable up and down to perform the compaction operation.

[0007] Preferably, the lower drive roller of the transmission mechanism is mounted on the lower table of the press via a lower bearing seat, the sprocket is located at one end of the lower drive roller and connected to the driven roller group via a chain, the servo motor drives the lower drive roller to rotate via a reducer and a coupling, and the upper driven roller is mounted on the upper table of the press via an upper bearing seat and works with the lower drive roller to form a transmission path.

[0008] Preferably, the transmission mechanism further includes a lower support plate disposed on the lower roller assembly for supporting the timber, and an upper support plate disposed below the upper roller assembly. The lower support plate and the upper support plate together constitute the timber compaction station to ensure stable positioning of the timber during the compaction process.

[0009] Preferably, the servo motor starts automatically after the hydraulic mechanism completes the compaction operation, and the compacted wood is conveyed out of the device through the transmission mechanism. The hydraulic cylinder then drives the upper table of the press to rise and reset to achieve continuous production cycle.

[0010] Preferably, the hydraulic mechanism and the transmission mechanism are integrated and fixed by the press frame, and the whole device has a compact structure and coordinated operation. The pressing action of the hydraulic cylinder and the transmission action of the servo motor are coordinated by the timing of the control system to improve production efficiency.

[0011] The advantages of this utility model are: 1. This utility model achieves precise and controllable wood conveying through the transmission chain design of the lower active roller driven by a servo motor. The servo motor transmits power through a reducer and coupling, and the sprocket and chain drive the driven roller group to operate synchronously, forming a stable transmission path. This ensures that the wood is accurately positioned and efficiently conveyed between the compaction station and the outlet, avoiding the errors and inefficiencies of manual handling. Through the compaction station design with the lower and upper support plates working together, a stable positioning function is achieved during the wood compaction process. The lower support plate supports the wood raw material, and the upper support plate is pressed down with the upper table of the press. Together, they form a closed compaction space, ensuring uniform pressure distribution and preventing the wood from shifting. This solves the problem of unstable positioning affecting the quality of the finished product during the compaction process, improving the consistency of compaction molding and the product yield. 2. This utility model achieves seamless integration of the compaction and conveying processes through the timing control design of the hydraulic cylinder and servo motor. After the hydraulic cylinder completes compaction, the servo motor immediately starts the transmission mechanism to deliver the finished product. Simultaneously, the hydraulic cylinder drives the upper platform to reset. The entire cycle is automatically coordinated by the control system, solving the efficiency loss problem caused by inter-process interruptions and realizing true continuous production. The combination design of continuous oil supply from the oil tank and heat insulation plate ensures the stability and safety of the hydraulic system. The oil tank provides a stable hydraulic oil source for the hydraulic cylinder, and the heat insulation plate prevents heat transfer during the compaction process to the lower part of the frame, ensuring both the long-term reliability of the hydraulic power and avoiding the impact of thermal deformation on the equipment's precision, thus improving the overall operational reliability of the device.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1-4 As shown, a wood compaction machine transmission device includes a hydraulic mechanism and a transmission mechanism. The hydraulic mechanism includes a press frame 17 and a hydraulic cylinder 15 installed on the upper part of the press frame 17 for providing compaction power. The transmission mechanism includes a lower drive roller 3 set on the lower table 1 of the press and an upper driven roller 10 set on the upper table 2 of the press for supporting and transporting wood. A servo motor 7 drives the lower drive roller 3 to rotate to realize automated wood transport. During operation, the device places the wood to be compacted on a pre-set conveying path between the lower driving roller 3 and the upper driven roller 10 of the transmission mechanism. The hydraulic cylinder 15 of the hydraulic mechanism is activated, and the piston rod of the hydraulic cylinder 15 extends downward, driving the upper platform 2 of the press connected to it to move downward. This causes the upper driven roller 10 and the upper support plate 13 installed below the upper platform 2 of the press to descend together, applying high pressure to the wood located on the lower driving roller 3 and the lower support plate 12, thus completing the compaction process. After the compaction process is completed, the hydraulic cylinder 15 controls the upper platform 2 of the press to rise slightly to release the pressure on the wood but still maintain a close state. Subsequently, the control system automatically starts the servo motor 7 of the transmission mechanism. The servo motor 7 drives the lower driving roller 3 to rotate through the reducer 8 and the coupling 9. The lower driving roller 3 drives the entire roller group to rotate through the sprocket 5 and the chain 6, thereby smoothly and automatically conveying the compacted wood from the compaction station, realizing continuous operation of compaction and conveying.

[0017] Furthermore, the hydraulic mechanism also includes an oil tank 14 installed on the top of the press frame 17 and connected to the oil cylinder 15 to continuously supply hydraulic oil. The heat insulation plate 16 is fixed to the lower part of the press frame 17 and the lower press table 1 is installed on the heat insulation plate 16. The upper press table 2 is connected to the oil cylinder 15 and can move up and down to perform the compaction operation. During operation, the hydraulic system of the hydraulic mechanism consists of an oil tank 14, an oil cylinder 15, and related valve groups and pipelines. The oil tank 14 is installed on the top of the press frame 17, stores hydraulic oil, and is connected to the oil cylinder 15 through pipelines, providing a continuous and stable power source for the reciprocating motion of the oil cylinder 15. The lower platform 1 of the press is installed through a heat insulation plate 16 fixed to the lower part of the press frame 17. The heat insulation plate 16 can effectively block the high temperature generated during the pressing process from being transmitted to the frame. The upper platform 2 of the press is directly connected to the end of the piston rod of the oil cylinder 15. Driven by the oil cylinder 15, it makes precise vertical lifting and lowering movements along the guide rail of the frame to perform the pressing and releasing of the wood.

[0018] Furthermore, the lower drive roller 3 of the transmission mechanism is mounted on the lower table 1 of the press through the lower bearing seat 4, the sprocket 5 is set at one end of the lower drive roller 3 and connected to the driven roller group through the chain 6, the servo motor 7 drives the lower drive roller 3 to rotate through the reducer 8 and the coupling 9, and the upper driven roller 10 is mounted on the upper table 2 of the press through the upper bearing seat 11 and forms a transmission path together with the lower drive roller 3. During operation, the power transmission and support structure of the transmission mechanism is as follows: the lower drive roller 3 is supported and fixed on the lower table 1 of the press by the lower bearing seats 4 at both ends. A sprocket 5 is installed at one end of the lower drive roller 3, and a chain 6 is fitted on the sprocket 5 and the sprockets of other driven rollers to achieve synchronous power transmission. The power output by the servo motor 7 is transmitted to the shaft end of the lower drive roller 3 through the coupling 9 after the speed reduction and torque amplification by the reducer 8, driving it to rotate. At the same time, the upper driven roller 10 is supported on the upper table that can move up and down by the upper bearing seats 11 at both ends, corresponding to the lower drive roller 3, and together clamping and conveying the wood.

[0019] Furthermore, the transmission mechanism also includes a lower support plate 12 disposed on the lower roller assembly to support the wood, and an upper support plate 13 disposed below the upper roller assembly. The lower support plate 12 and the upper support plate 13 together constitute the wood compaction station to ensure stable wood positioning during the compaction process. During operation, to ensure that the wood does not shift and is subjected to uniform force during high-pressure compaction, a flat lower support plate 12 is installed above the lower roller assembly consisting of the lower driving roller 3 and its driven rollers to support the lower surface of the wood. Correspondingly, an upper support plate 13 is installed below the upper roller assembly consisting of the upper driven roller 10. When the upper table 2 of the press descends to perform compaction, the upper support plate 13 descends accordingly, and together with the lower support plate 12 below, presses the wood together in the middle to form a stable compaction cavity, thus preventing the wood from deforming or shifting due to the gap between the rollers under high pressure.

[0020] Furthermore, the servo motor 7 automatically starts after the hydraulic mechanism completes the compaction operation, and conveys the compacted wood out of the device through the transmission mechanism. The hydraulic cylinder 15 then drives the upper table 2 of the press to rise and reset to achieve continuous production cycle. During operation, the control logic for achieving continuous production cycle is as follows: when the hydraulic mechanism drives the upper table 2 of the press to complete the pressing of the wood and reach the required compaction time, the hydraulic cylinder 15 controls the upper table to rise slightly by a small distance, so that the upper support plate 13 is slightly separated from the upper surface of the wood but remains very close. At this time, the control system immediately sends a start command to the servo motor 7, and the servo motor 7 drives the roller to quickly transport the compacted wood out of the compaction station. After the wood is delivered, the hydraulic cylinder 15 drives the upper table 2 of the press to rise completely to the initial high position, waiting for the next piece of wood to enter, thus forming an automated cycle of "compaction-slight lifting-transportation-reset".

[0021] Furthermore, the hydraulic mechanism and the transmission mechanism are integrated and fixed by the press frame 17. The entire device has a compact structure and coordinated operation. The pressing action of the hydraulic cylinder 15 and the transmission action of the servo motor 7 are coordinated by the control system to improve production efficiency. During operation, all components of the hydraulic mechanism and transmission mechanism are installed and fixed on the press frame 17 as the main frame. The hydraulic cylinder 15 and oil tank 14 are installed on the upper part of the frame, the lower table, upper table and roller conveyor system are installed in the middle of the frame, and the servo motor 7 and reducer 8 are installed on the side of the frame, forming a compact and rationally laid-out overall equipment. A central control system receives sensor signals and, according to a preset program, precisely coordinates the lifting and pressing of the hydraulic cylinder 15 and the starting, stopping and speed of the servo motor 7, so that the two core actions of pressing and conveying are seamlessly connected and efficiently coordinated in time and space.

[0022] Working principle: The servo motor 7 drives the lower drive roller 3 to rotate through the reducer 8 and coupling 9. The lower drive roller 3 drives the driven roller group to rotate synchronously through the sprocket 5 and chain 6, thereby conveying the wood to the compaction station composed of the lower support plate 12 and the upper support plate 13. At this time, the hydraulic cylinder 15 pushes the upper table 2 of the press down with the oil supply from the oil tank 14, so that the upper driven roller 10 and the upper support plate 13 compact the wood. After the compaction is completed, the hydraulic cylinder 15 drives the upper table to rise and reset. At the same time, the servo motor 7 starts immediately and sends the finished wood out of the device through the transmission mechanism, thereby realizing the automated continuous production cycle of compaction and conveying.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
