Description

Technical Field

[0001] This utility model relates to the field of feeding in reed processing, and specifically to an auxiliary feeding device for reed processing. Background Technology

[0002] As a typical representative of non-wood materials, reeds, when used as raw materials to produce engineered wood products, can not only save on deforestation and reduce carbon emissions, but also effectively solve the environmental pollution and ecological damage caused by the lack of proper management of wild reeds. Currently, the non-wood engineered wood product industry, represented by reeds and crop straw, is developing rapidly and has become a new growth point in the engineered wood product market.

[0003] However, significant technical bottlenecks exist in the primary processing of non-wood materials such as reeds during actual production. Traditional processing methods use conveyor belts to directly transport reed material to a slicer for cutting. However, due to the varying lengths and irregular shapes of reed stalks, uneven accumulation is easily observed during transport. This disordered feeding method leads to frequent blockages and entanglement at the slicer inlet, severely impacting processing efficiency and increasing equipment maintenance costs. Especially in continuous production, poor feeding causes fluctuations in the slicer's load, consequently affecting cutting quality and yield. Existing technologies lack effective pretreatment devices to address the issue of uniform reed feeding before it enters the slicer, which has become a key technical obstacle restricting the large-scale development of the non-wood engineered wood products industry. This device, through an innovative forced feeding mechanism design, achieves orderly conveying and height adjustment of the reed material, providing a stable and reliable feeding guarantee for subsequent cutting processing.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-3 As shown, this application proposes an auxiliary feeding device for reed processing, including a slicer for cutting and processing reed material. The inlet of the slicer is equipped with a reed material feeding conveyor belt, and a feeder is provided at the connection between the outlet of the feeding conveyor belt and the inlet of the feeder. The feeder includes a roller frame, and multiple feeding rollers for forced pressing are rotatably installed inside the roller frame. The roller frame is connected to a support frame through a rotation adjustment component for adjusting the feeding height.

[0018] The feeding conveyor belt transports the reed material to the slicer. This conveyor belt can be a belt conveyor with baffles on both sides. The feeder is located between the conveyor belt outlet and the slicer inlet, facilitating material transfer and forced feeding. The roller frame, as the main framework of the feeder, can be a welded steel plate structure or a profile assembly structure, with multiple feeding rollers mounted internally via bearings. The surface of the feeding rollers has several rows of evenly distributed protruding toothed racks, and the roller diameter can be selected within the range of 200-500mm. A rotary adjustment component allows for adjustment of the roller frame angle, specifically through a hinge mechanism with screw adjustment or hydraulic cylinder adjustment. The support frame can be a column type or a gantry type structure.

[0019] This technical solution solves the problem of blockage at the slicer inlet caused by the varying lengths and disordered arrangement of reeds. Multiple feeding rollers provide progressive pressure, ensuring a smooth entry of the material into the slicer. A rotary adjustment component allows for adjustment of the feeding angle based on material characteristics, optimizing the feeding effect. Compared to existing technologies that directly use a conveyor belt for feeding, this device significantly improves the stability and continuity of feeding, reduces downtime for cleaning, and increases processing efficiency.

[0020] Furthermore, this application also proposes that the plurality of feeding rollers include three feeding rollers, namely a first feeding roller, a second feeding roller, and a third feeding roller, which are arranged in a stepwise manner from the outlet of the feeding conveyor belt to the inlet of the feeder, and the first feeding roller, the second feeding roller, and the third feeding roller are rotatably supported inside the roller frame.

[0021] Specifically, the three feeding rollers are arranged in a stepped configuration, with the first feeding roller at the highest position and the third feeding roller at the lowest position, forming a progressively descending material conveying path. In a preferred embodiment, the height difference between adjacent feeding rollers can be set to 50-100mm to ensure a smooth transition of the reed material. The rotational support of the feeding rollers is achieved through bearing assemblies, with bearing seats fixed to both sides inside the roller frame. Furthermore, the surface of the feeding rollers can be provided with anti-slip textures or raised toothed structures to enhance the traction force on the reed material.

[0022] Therefore, this technical solution, through a three-stage stepped arrangement of feeding rollers, effectively solves the problem of reed material easily accumulating and clogging during transportation. When the reed material enters the feeder from the feeding conveyor belt, it is first received and initially pressed by the first feeding roller, and then continuously conveyed by the second and third feeding rollers in sequence, forming a gradual material propulsion process. This arrangement not only ensures the continuity of material transportation, but also maintains a uniform distribution of the reed material through multi-stage roller pressing, avoiding congestion at the slicer inlet. Compared with the single-roller conveying method in the prior art, this solution significantly improves the conveying efficiency and processing stability of the reed material.

[0023] Furthermore, this application also proposes that a drive motor is installed on the outside of the roller frame, and the drive motor is synchronously connected to gears installed on the outer ends of multiple feed rollers through a transmission chain.

[0024] Specifically, the drive motor is fixed to the outside of the roller frame and stably installed via bolt connections. The drive chain is a standard roller chain, with both ends meshing with the drive sprocket on the output shaft of the drive motor and the driven sprocket on the outer end of the feed roller, respectively. The gears are spur gears, fixed to the shaft end of the feed roller via key connections. Additionally, a tensioning wheel mechanism can be installed on the drive chain to adjust its tension.

[0025] Therefore, this technical solution achieves synchronous rotation of multiple feeding rollers through a motor-driven chain transmission system. The chain drive is characterized by its simple structure and high transmission efficiency, ensuring consistent rotational speeds for all feeding rollers and preventing material accumulation or blockage caused by speed differences. Compared to existing technologies that individually drive each feeding roller, this solution significantly simplifies the transmission structure, reduces equipment manufacturing costs, and lowers maintenance complexity. Simultaneously, synchronous transmission ensures the continuity and stability of the feeding process, effectively improving the conveying efficiency of reed material.

[0026] Furthermore, this application also proposes that the rotation adjustment assembly includes support frames disposed on both sides of the feeder inlet, and the support frames on both sides are rotatably connected to the upper end of the feeder roller frame tail via a rotating shaft.

[0027] Specifically, the support frames in the rotary adjustment assembly are symmetrically arranged and fixed on both sides of the feeder inlet. The rotating shaft passes through the upper end of the roller frame's tail, forming a rotating pair connection with the support frames. As a preferred embodiment, the rotating shaft can be a steel shaft with self-lubricating bearings, with a diameter ranging from 50-80mm to meet load-bearing requirements. Furthermore, the support frame can be a welded steel structure, its bottom fixed to the foundation with anchor bolts. An axial positioning retaining ring can be installed at the connection between the rotating shaft and the roller frame to prevent axial movement. Thus, the roller frame can rotate around the rotating shaft, achieving adjustment of the feeding height.

[0028] To address this issue, this technical solution utilizes a rotary connection structure to achieve flexible adjustment of the roller frame angle. When the feeding height needs adjustment, the roller frame can rotate around its axis, changing the relative position of the feeding roller and the conveyor belt outlet. This adjustment method is simple, reliable, and easy to operate, and can adapt to the feeding requirements of reeds of different specifications. Compared with existing fixed-height feeding devices, this solution solves the problem of material blockage caused by improper feeding height, improving the stability and adaptability of the feeding process.

[0029] Furthermore, this application also proposes that lifting cylinders are provided on both sides of the roller frame and are hinged to the sides of the corresponding support frame. The lifting cylinders are connected to the hydraulic power unit through oil pipes.

[0030] The lifting cylinder is hydraulically driven and connected to the hydraulic power unit via oil lines to achieve precise adjustment of the roller frame height. The lifting cylinder can be a single-acting or double-acting hydraulic cylinder, with the stroke determined by the feeding height adjustment range. As a preferred embodiment, the cylinder ends are connected by ball joints to accommodate angle changes during roller frame rotation. The hydraulic power unit can be a gear pump or a piston pump, equipped with an overflow valve and a directional valve for pressure control and direction switching. The oil lines use high-pressure hoses or rigid pipes, and throttle valves can be installed on the lines to regulate the cylinder lifting speed.

[0031] Specifically, this technical solution achieves stepless adjustment of the roller frame height through a hydraulically driven lifting cylinder, solving the problem of needing to dynamically adjust the reed feeding height according to the material characteristics. Compared to manual adjustment, hydraulic drive offers advantages such as less effort and more precise positioning. When the feeding height needs adjustment, the hydraulic power unit supplies oil to the lifting cylinder through oil lines, pushing the cylinder piston rod to extend or retract, causing the roller frame to rotate around its axis, thereby changing the relative height between the feeding roller and the conveyor belt. This adjustment method can adapt to reeds in different stacking states, ensuring a smooth transition of material to the feeding roller area.

[0032] Furthermore, this application also proposes that the lower part of the roller frame is connected to a feed chute to prevent the reed material from spreading.

[0033] The feed trough can be welded from metal sheets, preferably with a frame-shaped cross-section. The two edges of the trough are bolted to the bottom of the roller frame. As a preferred embodiment, a wear-resistant lining, such as high-manganese steel or polyurethane composite material, can be installed on the inner surface of the feed trough. The installation angle of the feed trough can be adjusted according to actual working conditions, typically at a 15-30 degree angle to the horizontal plane to ensure the reed material slides smoothly into the slicer. Specifically, the length of the feed trough should cover at least the projected area of ​​three feeding rollers, with its front end extending approximately 50-100mm below the outlet of the feeding conveyor belt, and its rear end maintaining a 10-20mm gap from the slicer's inlet.

[0034] This technical solution effectively solves the problems of splashing and spreading of reed material during forced feeding by adding a feeding trough structure. When the stepped feeding rollers compress and convey the reed material, the feeding trough forms a closed flow channel, keeping the loose material within the predetermined conveying trajectory. This avoids equipment blockage caused by lateral material spillage and reduces raw material waste. Compared with existing open conveying methods, this design significantly improves the stability and continuity of the feeding process, providing a uniform and orderly material flow for subsequent slicing processes.

[0035] The implementation principle of the auxiliary feeding device for reed processing in this application embodiment is as follows:

[0036] When in use, the reed material is conveyed to the feed trough 13 of the feeder 2 via the feeding conveyor belt 1. Since the reed material is relatively loose, it is difficult for the conveyor belt to carry it in. The reed comes into contact with the three forced feeding rollers 9, 10 and 11 shown in the feeder 2 in sequence, and is thus compressed and forced into the slicer 3 for cutting.

[0037] The drive motor 7 of the feeder 2 drives the first feed roller 9, the second feed roller 10, and the third feed roller 11 to rotate via chain transmission. The three feed rollers are mounted on the roller frame 5 and rotate synchronously. The roller frame 5 is connected to the support frame 4 via the lifting cylinder 12. The entire roller frame 5 is mounted on the support legs via the rotating shaft and bearings. When the thickness of the fed reeds changes, the height of the lifting cylinder 12 is adjusted to assist the height of the feed rollers, so that the feed rollers can compress and force-feed the loose materials of different thicknesses into the rear reed cutting equipment. At the same time, when it is necessary to repair and clean the material wrapped inside the feed rollers, the lifting cylinder 12 can be extended to open the entire roller frame 5 upwards to expose the feed rollers for easy cleaning.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
