Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wood feeding, in particular to a feeding mechanism for wood processing. BACKGROUND

[0002] Wood processing feeding is a key link between raw materials and processing equipment in the wood processing process, directly affecting processing efficiency, precision and product quality. Its core role is to stably and accurately transport raw materials such as logs and boards to sawing, planing, milling and other processing equipment to ensure that the raw materials complete processing according to the preset parameters. The current mainstream feeding methods are divided into mechanical feeding and automatic feeding;

[0003] The patent application with publication number CN113415586B discloses a feeding mechanism for wood processing, which comprises a first support, a second support fixedly connected inside the first support, a motor fixedly installed on the upper side of the second support, a first sprocket fixedly installed on the output end of the motor, a first U-shaped frame and a second U-shaped frame rotatably connected at both ends of the second support, a second sprocket fixedly connected to the outer side of the first U-shaped frame, and a chain transmission connection between the first sprocket and the second sprocket. When the cross beam starts to move downward, the J-shaped connecting frame moves downward, the J-shaped connecting frame pulls the traction rope to move the push plate outward, the push plate compresses the spring, so that there is more space between the two push plates for placing wood. The wood is placed between the two groups of spacer blocks. After the cross beam moves to the lowest point, the cross beam starts to move upward, the compressed spring pushes the push plate to move inward. When the wood is not placed in the center, the push plate pushes the wood to move, so that the wood is distributed in the center, thereby improving the stability of subsequent wood conveying;

[0004] In the field of wood processing, the feeding mechanism is an essential device for smoothly and continuously conveying wood to subsequent processing units such as sawing and planing. In order to ensure processing quality, the wood needs to be cleaned of impurities such as bark, sand, and wood chips attached to its surface before or during conveying.

[0005] Currently, the common practice is to use functionally independent equipment for segmented processing: first, use a dedicated feeding machine to complete the conveying of wood, and then use manual or another independent cleaning device (such as a brush roller machine or a blowing device) for cleaning. This separate operation mode of "conveying-transferring-cleaning" can complete the basic functions, but there is a significant efficiency bottleneck: since feeding and cleaning are two independent and separate processes, the wood needs to be transferred or repositioned in the middle, resulting in an incoherent overall processing flow, large equipment footprint, and a serious constraint on production rhythm, which reduces overall processing efficiency. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a feeding mechanism for wood processing to solve the problems raised in the background art.

[0007] To achieve the above object, the present application is implemented by the following technical scheme: a feeding mechanism for wood processing, comprising a placing rack, the top of the placing rack is fixedly connected with a wood conveying mechanism;

[0022] A feeding mechanism for wood processing, comprising a placing rack, the top of the placing rack is fixedly connected with a wood conveying mechanism; the inner wall of the placing rack is also fixedly connected with a rotating mechanism.

[0023] The wood conveying mechanism comprises:

[0024] A connecting bearing is movably connected to the top of the placing rack. The outer wall of the connecting bearing is rotatably connected with a rotating roller. This design enables the rotating roller to make a certain range of sinking movement relative to the placing rack when bearing the weight of wood, forming a floating support structure.

[0025] A chain type round roller is movably connected to the inner wall of the placing rack and located below the rotating roller.

[0026] A telescopic machine is fixedly connected to the outer wall of the placing rack through a first support. The output end of the telescopic machine is movably connected with a jacking rod, and the top end of the jacking rod is movably connected with the chain type round roller.

[0027] The rotating roller movably contacts with the rotating mechanism, and the rotating mechanism provides driving force to make it rotate, thereby rubbing and conveying the wood placed thereon.

[0028] The rotating mechanism comprises:

[0029] A first motor is fixedly connected to the outer wall of the placing rack through a second support.

The second motor is preferably set to a forward and reverse rotation mode to drive the rotating shaft to reciprocate.

[0040] The present application provides a feeding mechanism for wood processing. It has the following advantages:

[0041] 1. The feeding mechanism for wood processing integrates the wood conveying mechanism and the cleaning function, so that the wood can be preliminarily cleaned during the conveying process. Specifically, the wood is moved by the rotating roller, and the impurities are removed by the flipping of the chain-type round roller and the friction of the cleaning belt, thereby eliminating the subsequent separate cleaning process, effectively shortening the overall process time of wood processing, and improving the production efficiency.

[0042] 2. The feeding mechanism for wood processing, the rotating roller is movably connected to the top of the placing rack by a connecting bearing, so that it can be self-adaptively sunken when bearing the weight of the wood, which can stably support the wood and ensure effective contact with the rotating belt below, thereby maintaining stable driving force. This floating design enables the mechanism to adapt to the conveying needs of wood of different diameters or weights, and has strong versatility.

[0043] 3. The feeding mechanism for wood processing, the cleaning mechanism of the present application is not a single static state, but combines multiple dynamic actions: first, when the chain-type round roller is lifted by the lifting rod, it can slightly push the wood to make the wood rub against each other and shake off the loosely adhered impurities; second, the lifting of the chain-type round roller will locally lift the rotating belt, so that the rotating belt rubs against the bottom surface of the wood to clean the contact surface; finally, the independent cleaning belt mechanism can clean the side surface and upper surface of the wood through reciprocating motion. This comprehensive cleaning mode from the bottom, side to the interaction between the wood significantly improves the cleaning effect of the impurities and debris on the surface of the wood.

[0044] 4. The feeding mechanism for wood processing, through the gap between the multiple rotating rollers, and the larger space below the chain type circular roller area, the impurities, debris and adhesion dropped during the conveying and turning of the wood can naturally and smoothly fall through the gap, avoiding the accumulation on the conveying surface, reducing the influence on the operation of the mechanism, and facilitating the setting of the dust collection device below for unified collection, maintaining the cleanliness of the working environment.

[0045] 5. The feeding mechanism for wood processing, the rotating mechanism constitutes a stable transmission system by the driving roller, the driven roller and the rotating belt, providing continuous power for the rotating roller. At the same time, the main components such as the telescopic machine, the first motor, the second motor, etc. are fixedly connected with the main body structure through the support, ensuring the rigidity and stability of the mechanism during operation, prolonging the service life of the equipment.

[0046] 6. The feeding mechanism for wood processing, the cleaning belt is fixed by the simple connection of the hook and the hanging disc, and the installation and disassembly are very convenient for maintenance or replacement. The introduction of the spring element makes the cleaning belt have certain elastic buffer when in frictional contact with the wood, which can ensure effective cleaning strength and avoid damage to the wood surface caused by rigid pulling or damage of the cleaning belt due to excessive stress.
