Description

Technical Field

[0001] This utility model belongs to the technical field of long timber slicer, and more specifically, it relates to a long timber pressing device, which is mainly used to achieve stable pressing and conveying of long timber. Background Technology

[0002] In the particleboard and other engineered wood product processing industries, long timber chippers are commonly used equipment. These chippers use conveyor systems to feed long timber into the chipper for chipping. Currently, long timber is mostly conveyed using chain conveyors, which are typically over 10 meters long. Chain conveyors generate significant vibration during operation, which often causes long timber from the upper layers to fall during transport. Although there are baffles on both sides of the chain conveyor, the height of these baffles is fixed and cannot be adjusted according to the amount of timber being conveyed.

[0003] Secondly, in actual processing, to improve production efficiency, the timber conveying capacity of chain conveyors is usually large. Due to the excessive weight of long timbers, slippage is common, meaning the chain conveyor moves forward, but the long timbers do not, causing the planing work to stall and severely impacting processing efficiency. Furthermore, when the timber conveying capacity is large, long timbers frequently fall off. Falling timbers not only affect production efficiency and interrupt normal processing, but can also lead to safety accidents, threatening the personal safety of operators. In addition, repositioning fallen long timbers increases labor and time costs. Currently, there is no long timber clamping device that can flexibly adjust according to the timber conveying capacity and effectively prevent slippage of long timbers and prevent timber from falling due to chain conveyor vibration. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a long timber pressing device, which enables the pressing mechanism to rotate while its height and angle can be flexibly adjusted. The position of the pressing mechanism can be flexibly adjusted according to the conveying volume of long timber, so as to ensure reasonable and effective clamping force between the long timber and the conveying device. It is suitable for conveying long timber and branches of various specifications, effectively avoids slippage of long timber during conveying and falling due to vibration of the chain conveyor during the conveying process, and greatly improves the versatility of the device.

[0005] The long material pressing device includes a fixed frame and a swing arm assembly. One end of the swing arm assembly is rotatably connected to the fixed frame. A telescopic mechanism is movably connected between the fixed frame and the swing arm assembly. The other end of the swing arm assembly is rotatably connected to a pressing mechanism for pressing the long material during conveying. A power device for driving the pressing mechanism to rotate is fixedly connected to the swing arm assembly.

[0006] Preferably, the pressing mechanism includes a pressing shaft, which is rotatably connected to the swing arm assembly. A pressing middle roller is fixedly connected to the middle of the pressing shaft, and pressing side rollers are respectively provided at both ends of the pressing shaft. The pressing middle roller and the pressing side rollers are coaxially arranged with the pressing shaft. The pressing side rollers are fixedly connected to the pressing shaft, and pressing tooth plates are fixedly connected to the outer side walls of the pressing middle roller and the pressing side rollers.

[0007] Preferably, the pressing teeth are arranged along the axial direction of the pressing shaft, and there are multiple pressing teeth, which are evenly distributed.

[0008] Preferably, at least one fixed disc is fixedly connected inside the pressing roller, and the pressing shaft passes through the fixed disc and is fixedly connected to the fixed disc.

[0009] Preferably, at least one fixed disk II is fixedly connected inside the pressing side roller, and the pressing shaft passes through the fixed disk II and is fixedly connected to the fixed disk II.

[0010] Preferably, at least one fixed disk II is fixedly connected inside the pressing roller, and a coaxial bushing is fixedly connected to the middle of the fixed disk II. The bushing is sleeved on the pressing shaft and fixedly connected to the pressing shaft.

[0011] Preferably, the swing arm assembly includes at least two arm bodies, a connecting rod is fixedly connected to the arm body, a rotating seat for mounting the telescopic mechanism is fixed on the connecting rod, a rotating hole is opened at one end of the arm body, and a support ring is fixedly connected to the other end of the arm body. The support ring is coaxial with the pressing mechanism and rotates in cooperation with it.

[0012] Preferably, the power unit drives the pressing mechanism to rotate through a transmission mechanism, which includes a driving gear and a driven gear. The driving gear is fixedly connected to the output end of the power unit, and the driven gear is coaxially fixedly connected to the pressing mechanism. The driving gear meshes with the driven gear.

[0013] Preferably, it also includes at least one central shaft, which is rotatably connected to the swing arm assembly. A central gear is fixedly connected to the central shaft, and the driving gear drives the driven gear to rotate through the central gear.

[0014] Preferably, the support ring has a transmission groove that matches the intermediate gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a swingable support arm assembly in conjunction with a pressing mechanism to enable the pressing mechanism to rotate while its height and angle can be flexibly adjusted. The position of the pressing mechanism can be flexibly adjusted according to the conveying volume of long timber, thereby ensuring reasonable and effective clamping force between the conveying device and the long timber, avoiding slippage during conveying. It is suitable for conveying long timber and branches of various specifications, effectively preventing long timber from falling off due to vibration of the chain conveyor during conveying, and greatly improving the versatility of the device.

[0017] 2. The outer walls of the pressing rollers and side rollers of the pressing mechanism are equipped with evenly distributed pressing teeth. The pressing teeth increase the contact area and friction with the wood surface, enabling simultaneous pressing from the middle and both sides of the wood, effectively resisting the vibration of the chain conveyor. Furthermore, gaps are left between adjacent pressing teeth to ensure the pressing effect while avoiding excessive damage to the wood surface. The rotation direction of the pressing mechanism is consistent with the conveying direction of the conveying device, enabling the long wood to be pressed while being driven forward, further preventing slippage during conveying.

[0018] 3. The swing arm assembly adopts an "L" shaped structure, which is symmetrically distributed and equipped with connecting rods to enhance strength. It is hinged with the rotating seat and the telescopic mechanism to achieve flexible rotation while ensuring structural stability and ensuring reliable operation of the device during work.

[0019] 4. The transmission mechanism uses a drive gear, a central gear, and a driven gear to precisely mesh. A transmission groove is opened on the support ring to cooperate with the central gear. The transmission groove ensures smooth and reliable transmission when the driven gear meshes with the central gear without compromising the structural strength of the support ring. At the same time, it makes the structure of the pressing mechanism more compact. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Example 1:

[0031] like Figures 1 to 7 As shown, a long material pressing device includes a fixed frame 1 and a swing arm assembly 3. The fixed frame 1 is used for fixed connection with existing long material conveyors such as chain conveyors. During manufacturing, the fixed frame 1 can be made of high-strength steel welded into a frame structure, with multiple mounting holes at the bottom, and is securely connected to the frame of the long material conveyor by bolts. One end of the swing arm assembly 3 is rotatably connected to the fixed frame 1, and a telescopic mechanism 2 is movably connected between the fixed frame 1 and the swing arm assembly 3. The other end of the swing arm assembly 3 is rotatably connected to a pressing mechanism 6 for pressing the long material during conveying. A power device 4 for driving the pressing mechanism 6 to rotate is fixedly connected to the swing arm assembly 3. During processing, hinge seats that cooperate with the swing arm assembly 3 and the telescopic mechanism 2 are welded to the fixed frame 1 to provide a rotational connection fulcrum for the swing arm assembly 3, ensuring that the entire pressing device remains stable during operation and can withstand the forces from the telescopic mechanism 2, the swing arm assembly 3, and the pressing mechanism 6.

[0032] like Figure 2 and Figure 5As shown, the swing arm assembly 3 includes at least two arm bodies 301. In this embodiment, it is preferred that there are two arm bodies 301, each with an L-shaped structure, and the two arm bodies 301 are symmetrically arranged. A connecting rod 302 is fixedly connected to each arm body 301. Preferably, the connecting rod 302 is fixedly located in the middle of the arm body 301. The connecting rod 302 is used to enhance the structural strength of the swing arm assembly 3 and to provide an installation base for the telescopic mechanism 2. A rotating seat 303 for mounting the telescopic mechanism 2 is welded and fixed to the connecting rod 302. The rotating seat 303 has a pin hole. Specifically, the telescopic mechanism 2 is preferably a hydraulic cylinder. The extended end of the telescopic mechanism 2 is rotatably connected to the pin hole of the rotating seat 303 through a pin shaft. The other end of the telescopic mechanism 2 is rotatably connected to a corresponding hinge seat on the fixed frame 1.

[0033] The short arm end of the support arm body 301 has a rotating hole 304, which is used to rotatably connect to the hinge seat on the fixed frame 1 via a pin, enabling flexible rotation of the swing support arm assembly 3. The long arm end of the support arm body 301 is fixedly connected to a support ring 306, which is coaxial with and rotatably engaged with the pressing mechanism 6. The support ring 306 supports and fixes the pressing mechanism 6 without hindering its rotation. The support ring 306 is a circular metal component, and a bearing 65 is fixedly connected to it. The bearing 65 provides stable support for the pressing mechanism 6 and reduces frictional resistance during rotation. During operation, the telescopic mechanism 2 is activated to ensure that the swing support arm assembly 3 can rotate flexibly around the fixed frame 1 when the telescopic mechanism 2 extends or retracts.

[0034] like Figure 2 As shown, the two arm bodies 301 are fixedly connected to a fixed base 308, and the power unit 4 is fixedly installed on the fixed base 308. The fixed base 308 improves the structural strength of the swing arm assembly 3 on the one hand, and provides an installation base for the transmission mechanism 5 on the other hand.

[0035] like Figure 2 and Figure 3 As shown, the pressing mechanism 6 includes a pressing shaft 64, which is mounted in the inner ring of the bearing 65, thereby achieving a rotatable connection between the pressing shaft 64 and the swing arm assembly 3. A pressing roller 61 is fixedly connected to the middle of the pressing shaft 64, as shown. Figure 4As shown, the pressure roller 61 is a hollow cylindrical structure made of high-strength seamless steel pipe. At least one fixed disc 6101 is welded to the inner arm of the pressure roller 61. The fixed disc 6101 is a circular metal disc with a shaft hole matching the pressure shaft 64. The pressure shaft 64 passes through the shaft hole and is fixed to the fixed disc 6101 by key connection or direct welding, ensuring that the pressure roller 61 and the pressure shaft 64 rotate synchronously. Multiple pressure tooth plates 63 are uniformly welded to the outer wall of the pressure roller 61. The pressure tooth plates 63 are made of wear-resistant alloy steel, with a trapezoidal tooth shape. The tooth tip width is slightly smaller than the tooth root width, increasing the contact area with the wood surface, improving the pressing effect, and preventing long pieces of wood from slipping.

[0036] The pressure shaft 64 has pressure side rollers 62 at both ends, which are also hollow cylindrical structures, similar to the structure of the pressure middle roller 61. Figure 6 As shown, at least one fixing disc 6201 is fixed to its inner wall by welding. The fixing disc 6201 can be fixed to the pressure shaft 64 by key connection or direct welding.

[0037] In this embodiment, both the middle pressing roller 61 and the side pressing roller 62 are coaxially arranged with the pressing shaft 64. Multiple pressing toothed plates 63 are arranged along the axial direction of the pressing shaft 64, and these plates are evenly distributed. This ensures effective pressing of the wood while preventing surface damage due to excessive density of the pressing toothed plates 63. The length of the pressing toothed plates 63 matches the length of the corresponding middle pressing roller 61 and side pressing roller 62. Their surfaces are treated with an anti-slip coating to increase friction with the wood surface and prevent slippage during transport.

[0038] like Figure 2 and Figure 3 As shown, the power unit 4 is preferably a geared motor. The power unit 4 drives the pressing mechanism 6 to rotate through the transmission mechanism 5. The transmission mechanism 5 includes a driving gear 501, a rotating gear 502, and a driven gear 503. The driving gear 501 is fixedly connected to the output end of the power unit 4 via a key. When the power unit 4 rotates, the driving gear 501 rotates synchronously. The driven gear 503 is coaxially fixedly connected to the pressing shaft 64 of the pressing mechanism 6 via a key. The driving gear 501 and the driven gear 503 mesh. When the power unit 4 is started, it rotates, causing the driving gear 501 to rotate synchronously. The meshing of the driving gear 501 and the driven gear 503 drives the pressing mechanism 6 to rotate.

[0039] It also includes at least one central shaft 305, which is rotatably connected to the swing arm assembly 3. A central gear 502 is fixedly connected to the central shaft 305, and the driving gear 501 drives the driven gear 503 to rotate through the central gear 502.

[0040] Example 2:

[0041] A long material pressing device includes a fixed plate 6201 with a coaxially arranged bushing 6202 fixedly connected to the middle. During processing, the mating ends of the bushing 6202 and the pressing shaft 64 can be matched with circular or polygonal structures. The outer end of the bushing 6202 is sealed and has a threaded hole 6203. In use, the bushing 6202 is fixed to the pressing shaft 64 with bolts.

[0042] Multiple pressing toothed plates 63 are also evenly fixed on the outer wall of the pressing side roller 62, which work together with the pressing toothed plates 63 on the pressing middle roller 61 to simultaneously press the long timber from both sides and the middle.

[0043] At least one central shaft 305 is rotatably connected between the two support arm bodies 301. Central shafts 305 are equipped with central gears 502 near both ends. The central gears 502 are fixedly mounted on the central shafts 305 via key connections. The driving gear 501 drives the driven gear 503 to rotate through the central gears 502. Specifically, the driving gear 501 transmits power to the central gear 502 by meshing with it, and the central gear 502 then transmits power to the pressing shaft 64 of the pressing mechanism 6 by meshing with the driven gear 503. This causes the pressing roller 61 and the pressing side roller 62 to rotate, thus pressing and assisting in the conveying of long timber. Everything else is the same as in Embodiment 1.

[0044] To facilitate the meshing of the intermediate gear 502 and the driven gear 503, a transmission groove 307 matching the intermediate gear 502 is provided on the side of the support ring 306 near the intermediate gear 502. Since the driven gear 503 is located inside the support ring 306, the support ring 306 can protect the driven gear 503 and prevent wood chips from entering the pressing mechanism 6. The transmission groove 307 ensures smooth and reliable transmission when the driven gear 503 meshes with the intermediate gear 502 without compromising the structural strength of the support ring 306. At the same time, it makes the structure of the pressing mechanism 6 more compact.

[0045] Example 3:

[0046] A long material pressing device is provided, wherein the bushing 6202 is interference-fitted with the pressing shaft 64, further enhancing the connection strength between the pressing side roller 62 and the pressing shaft 64. Other aspects are the same as in Embodiment 2.

[0047] like Figure 7 As shown, this utility model is used in conjunction with the conveying device 7 (chain plate machine) of a long timber chipper. The front end of the conveying device 7 of the long timber chipper is equipped with a planing and pressing mechanism 8. To ensure the installation stability of the device, the upper end of the fixing frame 1 can be fixedly connected to the planing and pressing mechanism 8 through a connecting rod, and the bottom of the fixing frame 1 is fixedly connected to the frame of the conveying device 7.

[0048] In use, long timbers and branches are placed longitudinally on the conveyor belt of the conveying device 7, meaning the length direction of the long timbers and branches is consistent with the conveying direction of the conveying device 7. Based on the quantity of long timber being conveyed, the telescopic mechanism 2 is activated. The telescopic mechanism 2 extends and retracts, causing the swing arm assembly 3 to rotate around its connection with the fixed frame 1, thereby adjusting the position and angle of the pressing mechanism 6, bringing it closer to the long timber and pressing it firmly. Subsequently, the power unit 4 is activated, outputting power to drive the drive gear 501 to rotate. The drive gear 501 transmits power to the driven gear 503 through the intermediate gear 502. The driven gear 503 drives the pressing shaft 64 to rotate, thereby causing the pressing roller 61 and the pressing side roller 62 to rotate synchronously, their rotation direction consistent with the conveying direction of the conveying device 7. Under the action of the pressing toothed plate 63, the pressing and conveying effect of the long timber is enhanced, effectively resisting the vibration of the conveying device 7. At the same time, the pressing toothed plate 63 drives the long timber forward, avoiding slippage and preventing the long timber from falling, achieving the appropriate pressing and conveying of the long timber.

[0049] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
