Description

Technical Field

[0001] This utility model relates to the field of composite timber strip feeding devices, and in particular to a vertically arranged feeding device for recycled composite timber strips. Background Technology

[0002] A vertically arranged feeding device for recycled composite timber strips belongs to the field of composite timber manufacturing equipment. It is mainly used in the production process of recycled composite timber to transport several recycled timber strips in an orderly manner in a vertical arrangement to the subsequent processing station, providing a stable material supply for the splicing, pressing and other processes of timber strips. The feeding stability and speed matching degree directly affect the production efficiency and processing quality of composite timber. Traditional feeding methods often affect production due to uneven speed, poor connection with subsequent processes, and problems with timber strip guidance and power matching.

[0003] To address the feeding requirements of wood strips in composite timber production, existing technologies have been optimized. Some devices use variable-speed motors to control the conveyor belt speed, attempting to improve feeding speed fluctuations. Others add simple baffles on both sides of the feeding path as guide structures to reduce wood strip deviation. Still other technologies improve power transmission stability by increasing conveyor belt friction to prevent wood strip slippage. However, these improvements mostly address single issues. Variable-speed motors can only initially adjust the speed but cannot accurately match the rhythm of subsequent processes. Simple baffle guidance cannot accommodate wood strips of varying lengths, and increasing power transmission does not solve the problem of uneven force distribution on wood strips of different lengths, failing to address the core challenges in feeding.

[0004] Existing feeding devices for recycled composite timber strips have significant drawbacks. Traditional feeding methods are prone to uneven feeding speeds, either exceeding the speed of subsequent processes, leading to material accumulation, or falling behind, causing delays and severely impacting production continuity. Furthermore, the timber strip guiding devices are mostly fixed structures. When faced with timber strips of varying lengths, shorter strips are prone to tipping over due to insufficient support, while longer strips are prone to shifting due to uneven force distribution at both ends. Additionally, the feeding power is often uniformly output, resulting in poor adaptability to different lengths of timber. This can lead to situations where short strips receive excessive power while long strips receive insufficient power, ultimately causing material jamming. This not only reduces feeding efficiency but may also damage the timber strips, affecting the processing quality of subsequent composite timber. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a feeding device for recycled composite timber strips, aiming to solve the problems in the existing technology, such as uneven feeding speed, which leads to material accumulation when feeding too fast and waiting time when feeding too slow, affecting continuous production; fixed guiding device, which makes long and short timber strips easy to fall or deviate; poor uniformity and matching of feeding power, which makes short timbers too powerful and long timbers too weak, easily causing material jamming, reducing efficiency and damaging timber strips.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vertically arranged feeding device for recycled composite wood strips, comprising an operating table, a feeding calibration mechanism and a chain support mechanism at the top of the operating table, the feeding calibration mechanism comprising a lower guide frame, a base shaft rotatably connected to the inner wall of the lower guide frame, a lower drive sprocket fixedly connected to the outer wall of the base shaft, a side fixing frame fixedly connected to the outer wall of the lower guide frame, an upper guide frame fixedly connected to the top of the side fixing frame, an upper drive sprocket rotatably connected to the outer wall of the side fixing frame, a transport chain rotatably connected to the outer walls of the upper and lower drive sprockets, a motor fixing frame fixedly connected to the top of the operating table, a transport motor fixedly connected to the top of the motor fixing frame, a chain drive shaft fixedly connected to the output end of the transport motor, a drive chain rotatably connected to the outer wall of the chain drive shaft, and the drive chain rotatably connected to the outer wall of the upper drive sprocket.

[0014] The feeding calibration mechanism also includes a discharge rack, the outer wall of which is fixedly connected to the outer wall of the operating table, and the discharge rack is located at the discharge end of the feeding calibration mechanism.

[0015] As a further description of the above technical solution:

[0016] The feeding calibration mechanism also includes a side wall guide bar, the outer wall of which is fixedly connected to the outer wall of the lower guide frame.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the side guide strip is slidably connected to a composite wood strip, and the outer wall of the composite wood strip is slidably connected to the outer wall of the transport chain.

[0019] As a further description of the above technical solution:

[0020] The upper guide frame and the lower guide frame are generally in the shape of a trumpet, and the distance between the upper guide frame and the lower guide frame gradually decreases along the feeding direction.

The side wall guide strip 215 is a strip-shaped component that guides and limits the side of the composite wood strip 4. The outer wall of the side wall guide strip 215 is fixedly connected to the outer wall of the lower guide frame 211. The side wall guide strip 215 is stably installed by being fixed to the lower guide frame 211. The composite wood strip 4 is slidably connected to the inner wall of the side wall guide strip 215.

The conveyor chain 218 is slidably connected to the outer wall of the conveyor chain 218, which can drive the composite wood strips 4 to move synchronously. The upper guide frame 214 and the lower guide frame 211 are in the shape of a trumpet. The entrance ends of the upper guide frame 214 and the lower guide frame 211 are relatively wide, which facilitates the entry of the composite wood strips 4. The distance between the upper guide frame 214 and the lower guide frame 211 gradually decreases along the feeding direction. The reduction of the distance between the upper guide frame 214 and the lower guide frame 211 can calibrate the composite wood strips 4 to ensure their vertical arrangement.

[0035] Working principle: This vertical feeding device for recycled composite wood strips uses the operating table 1 as the basic support platform. The vertical arrangement, stable conveying and speed adjustment of the composite wood strips 4 are achieved through the feeding calibration mechanism 2. The chain support mechanism 3 is used to prevent the transport chain 218 from collapsing and blocking. The two work together to solve the problems of uneven speed leading to material accumulation or waiting, easy tilting and deviation of wood strips, and easy collapse of the chain in traditional feeding devices. It is adapted to the wood strip feeding needs in the production of recycled composite wood and ensures continuous and efficient processing in the later stages.

[0036] When feeding and calibrating the composite wood strips 4, the core process is completed through the feeding and calibration mechanism 2. The operator first places the composite wood strips 4 to be conveyed vertically into the outer wall of the conveyor chain 218, and starts the conveyor motor 220 on the motor fixing frame 219 at the top of the operating table 1. The output end of the conveyor motor 220 drives the chain drive shaft 221 to rotate. The chain drive shaft 221 drives the upper power sprocket 216 on the outer wall of the side fixing frame 213 to rotate through the transmission chain 222 on the outer wall. The upper power sprocket 216 and the lower power sprocket 217 on the base shaft 212 on the inner wall of the lower guide frame 211 are connected through the conveyor chain 218. When the upper power sprocket 216 rotates, it synchronously drives the conveyor chain 218 and the lower power sprocket 217 to rotate, so that the upper and lower power transmission is consistent and the composite wood strips 4 move smoothly. The upper guide frame 214 and the lower guide frame 211 are generally in the shape of a trumpet, and the distance between them gradually decreases along the feeding direction. When the composite wood strip 4 moves with the conveyor chain 218, it is gradually calibrated and merged into a vertically arranged wood square under the guidance of the upper guide frame 214 and the lower guide frame 211. The side guide strip 215 on the outer wall of the lower guide frame 211 limits the composite wood strip 4 from the side to prevent it from tilting or shifting during the conveying process. Finally, the composite wood strip 4 is sent to the subsequent processing station by the discharge rack 223 at the discharge end of the feeding calibration mechanism 2. The conveyor motor 220 can adjust the speed to match the feeding speed with the rhythm of the subsequent process and avoid material accumulation or waiting for the process.

[0037] During the conveying process, the chain support mechanism 3 provides stable support for the transport chain 218 to prevent collapse and blockage. The outer wall of the support shaft bracket 311 is fixedly connected to the upper guide frame 214, and the chain support shaft 312, which is rotatably connected to the inner wall of the support shaft bracket 311, rotates synchronously with the movement of the transport chain 218. The chain retainer 313 on the outer wall of the chain support shaft 312 is rotatably connected to the transport chain 218, forming support from the inside of the transport chain 218. This prevents the transport chain 218 from collapsing due to its long length or the weight of the composite wood strips 4, ensuring that the transport chain 218 always maintains a stable transmission state, preventing blockage of the composite wood strips 4 due to chain collapse, reducing damage to the wood strips and interruption of feeding, and ensuring continuous and smooth feeding.
