Description

Technical Field

[0001] This utility model relates to wood processing equipment, and more particularly to a wood waste feeding device. Background Technology

[0002] Timber is widely used in the production of boards; in this process, timber is fed to a peeling machine, chipper, or shaving machine via a conveyor belt. The timber is transported stably on the conveyor belt so that metal detectors can detect metal impurities. Timber with metal contamination will be removed before it reaches its destination.

[0003] In practice, it was found that the purchased timber (both peeled and unpeeled) often had impurities such as stones, sand, mud, and bark chips attached to it. Therefore, insufficient peeling was caused within the scheduled peeling time / scheduled peeling machine stroke, and / or the quality of the chips and shavings was affected. Wood chips or shavings mixed with stones and sand also required significant processing costs. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems mentioned above, and to provide a wood waste removal feeding device that removes sand, mud and bark chips attached to the wood in advance, thereby improving the quality of subsequent wood processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wood waste removal and feeding device includes a roller conveyor mechanism and a conveyor belt. The roller conveyor mechanism is provided with a plurality of conveyor rollers arranged at intervals along the wood conveying direction. The conveyor rollers are drivenly connected to a first conveying motor. The plurality of conveyor rollers are adapted to tumble, shake and / or bounce the wood during conveying to shake off impurities attached to the wood. The gaps between the conveyor rollers are adapted to discharge impurities. The conveyor belt is adapted to receive the wood output by the roller conveyor mechanism.

[0007] Compared with existing technologies, the beneficial effects of this application include: eliminating stones, sand, mud and bark chips attached to wood in advance, eliminating blind spots in metal detection, reducing the risk of chipping and scraping, improving the quality of subsequent processes such as wood chipping, avoiding the mixing of sand, mud, mud powder and bark chips in wood chips, and ensuring the bonding strength of particleboard.

[0008] As an improvement to the above technical solution, the conveying roller is provided with multiple top flanges spaced apart along the axial direction. The top flanges are suitable for flipping the wood, causing the wood to flip to the side and / or shake into the gap between the top flanges.

[0009] As an improvement to the above technical solution, the top flanges of two adjacent transmission rollers are staggered, and the top flanges of two adjacent transmission rollers are adapted to drive the wood to continuously and / or repeatedly turn to the side. The top flanges are also adapted to lift the front end of the wood.

[0010] As an improvement to the above technical solution, the peripheral wall of the top flange is provided with multiple protrusions at intervals along the circumference. The protrusions are suitable for removing impurities from the peripheral wall of the wood and for aggravating the shaking and swaying of the wood.

[0011] As an improvement to the above technical solution, a transitional transmission mechanism is also included. The transitional transmission mechanism includes 1 to 4 toothed rollers arranged sequentially along the transmission direction. The toothed rollers are driven by a third material conveying motor. The roller transmission mechanism transmits the wood to the conveyor belt through the transitional transmission mechanism.

[0012] As an improvement to the above technical solution, it also includes two side stops, which define a material conveying channel suitable for conveying wood along the roller conveyor mechanism and the conveyor belt, the cross-section of which is an inverted trapezoid.

[0013] As an improvement to the above technical solution, it also includes two side blocks, which define a material conveying channel suitable for the wood to be conveyed along the roller conveyor mechanism and the conveyor belt. The two ends of the conveyor roller are provided with slag-blocking flanges, and the top material flange is arranged between the two slag-blocking flanges.

[0027] 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 protection scope of the present utility model.

[0028] Reference Figures 1 to 3 This utility model provides a wood waste removal and feeding device, including a frame 100, a roller conveyor mechanism 200 and a conveyor belt 400. The roller conveyor mechanism 200 and the conveyor belt 400 are mounted on the frame 100. The roller conveyor mechanism 200 is provided with a plurality of conveyor rollers 210 arranged at intervals along the wood conveying direction. The conveyor rollers 210 are drivenly connected to a first conveying motor. The plurality of conveyor rollers 210 are adapted to tumble, shake and / or bounce the wood during conveying to shake off the impurities attached to the wood. The gaps between the conveyor rollers 210 are suitable for impurity discharge. The conveyor belt 400 is adapted to receive the wood output by the roller conveyor mechanism 200.

[0029] It is understood that the conveyor belt 400 includes a belt, pulleys, and a second conveying motor that drives the pulleys. The two ends of the belt are wound around corresponding pulleys at their ends. Depending on the length of the conveyor belt 400, other pulleys can be arranged between the two end pulleys. The conveyor belt 400 is divided into multiple segments, representing an equivalent replacement for smooth transmission.

[0030] Both the first and second feeding motors can be electric motors (starters), pneumatic motors, or hydraulic motors. The connection between the motor and the pulley / roller can be a chain drive, belt drive, or gear drive, etc.

[0031] Understandably, wood is not an ideal straight cylinder. Wood has a certain degree of curvature, and / or the veneer is uneven, and / or there are scabs on the outside of the wood. Therefore, even if the wood does not extend in the left-right direction during transport, as the wood passes through the multiple transport rollers 210 in sequence, the wood will still roll, shake and / or bounce to some extent because it is not straight enough, causing the stones, mud and bark chips on the outer wall of the wood to fall off.

[0032] The operation process of this utility model can be as follows: a loader, a feeding hopper or an outlet belt, etc., pours the wood into the beginning of the roller conveyor mechanism 200. The wood is knocked down and most of the impurities (stones, sand, mud, bark chips) are shaken off, and / or the impurities are loosened. Most of the impurities are discharged through the gap between the rollers.

[0033] The wood is moved by multiple transmission rollers 210 of the roller conveying mechanism 200. Based on the fact that the wood has a certain degree of curvature and / or the transmission surface of the multiple transmission rollers 210 is uneven, the wood shakes, rolls and / or bounces to a certain extent, so that impurities on the surface of the wood are further removed.

[0034] After impurities are removed, the wood is fed to conveyor belt 400. Conveyor belt 400 is a planar conveyor, which allows the wood to move stably and makes it easy for metal detectors / CCD cameras on conveyor belt 400 to detect the presence of metal.

[0035] When the metal-coated wood reaches the middle or end of the conveyor belt 400, it is removed by the scraper / push plate / robotic arm, and the qualified wood is fed into the peeler / chipper / shaving machine.

[0036] Compared with existing technologies, the beneficial effects of this application include: eliminating stones, sand, mud and bark chips attached to wood in advance, eliminating blind spots in metal detection, reducing the risk of chipping and scraping, improving the quality of subsequent processes such as wood chipping, avoiding the mixing of sand, mud, mud powder and bark chips in wood chips, and ensuring the bonding strength of particleboard.

[0037] In practice, especially for non-particleboard manufacturers, straighter, smoother timber is generally preferred. To address the technical issues of tumbling / jittering / swaying amplitude of timber in the roller conveyor mechanism 200, reference was made to... Figures 1 to 3 In some embodiments of this utility model, the conveyor roller 210 is provided with a plurality of top flanges 220 at intervals along the axial direction. The top flanges 220 are suitable for flipping the wood, causing the wood to flip sideways and / or shake into the gap between the top flanges 220. That is, when the wood is supported on the top flanges 220, because the wood is approximately cylindrical, the top of the top flange 220 acts as a point that supports the cylinder, and the wood can only flip sideways to smash into the relatively stable gap between the top flanges.

[0038] Reference Figures 1 to 3In some embodiments of this utility model, the top flanges 220 of adjacent two conveying rollers 210 are staggered. The top flanges 220 are also adapted to lift the front end of the wood, causing the wood to sway and continuously flip over or repeatedly flip forward and backward while being conveyed. Specifically, the wood just falls into a gap of a top flange, but a new top flange 220 will stop in front of the gap, causing the front end / head of the wood to tilt upward. In addition, because the new top flange 220 divides into new top flange gaps on both sides, the old and new top flange gaps are staggered. After the wood tilts upward through the new top flange 220, it will again be difficult to stabilize and will flip over to the new top flange gap.

[0039] Reference Figures 1 to 3 In some embodiments of this utility model, the peripheral wall of the top flange 220 is provided with a plurality of protrusions 221 spaced apart along the circumference, making the top flange 220 gear-shaped. The protrusions 221 are suitable for removing impurities from the peripheral wall of the wood and for aggravating the shaking and swaying of the wood. It is understood that the protrusions 221 are not scraper blades. The protrusions 221 are not good at cutting and scraping the bark. The roller conveyor mechanism 200 is not good at scraping the bark, but is suitable for removing impurities from the peripheral wall of the wood.

[0040] Reference Figures 1 to 3 In some embodiments of this utility model, a transition transmission mechanism 300 is also included. The transition transmission mechanism 300 includes one to four toothed rollers 310 arranged sequentially along the transmission direction. The toothed rollers 310 are drivenly connected to a third material conveying motor. The roller transmission mechanism 200 transmits the wood to the conveyor belt 400 through the transition transmission mechanism 300. (See reference...) Figures 1 to 3 The wolf-tooth roller 310 is named so because its shape resembles a wolf-tooth club. This utility model is equipped with 1 to 4 wolf-tooth rollers 310, which enables the wood to be effectively transferred from the roller conveyor mechanism 200 to the conveyor belt 400, and the 1 to 4 wolf-tooth rollers 310 cause very little damage to the outer surface of the wood; preferably, 2 wolf-tooth rollers 310 are provided.

[0041] Reference Figure 1 , 2 and Figure 4 In some embodiments of this utility model, two side blocks 500 are also included. The two side blocks 500 define a conveying channel suitable for conveying wood along the roller conveyor mechanism 200 and the conveyor belt 400. The cross-section of the conveying channel is an inverted trapezoid, which makes the wood tend to be centered and lean back rather than sideways. It can be understood that in some cases, the conveying channel is designed to be heightened, that is, an inverted trapezoid superimposed with a rectangle, which is an equivalent replacement.

[0042] Reference Figure 4In some embodiments of this utility model, two side baffles 500 are also included. The two side baffles 500 define a material conveying channel suitable for the conveying of wood along the roller conveyor mechanism 200 and the conveyor belt 400. Slag-blocking flanges 230 are provided at both ends of the conveyor roller 210, and top material flanges 220 are arranged between the two slag-blocking flanges 230. The gap between the slag-blocking flange 230 and its adjacent top material flange 220 is inserted by the lower end of the corresponding side baffle 500. In this utility model, the gap between the top material flanges 220 and the gap between the conveyor rollers 210 are the main discharge gaps for impurities; a few impurities may have a tendency to escape laterally. The lower end of the side baffle 500 forms a primary baffle, and the slag-blocking flange 230 forms a secondary baffle, effectively preventing impurities such as sand, gravel, and mud powder from falling onto the bearing at the end of the conveyor roller 210. It can be understood that the side baffle 500 is divided into multiple segments, which are equivalent replacements.

[0043] In some embodiments of this utility model, a dust collection hood is provided above the roller conveyor mechanism 200 and / or the conveyor belt 400, and the dust collection hood is connected to a dust collector. The dust collector includes an exhaust fan and a filter element, which may be a filter bag, a filter cartridge, and / or electrostatic precipitator fins, etc.

[0044] In some embodiments of this utility model, a slag-collecting belt is provided below the roller conveyor mechanism 200. The slag-collecting belt includes a belt, pulleys, and a corresponding conveying motor.

[0045] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
