Description

Technical Field

[0001] This invention relates to the field of wood processing and production, and in particular to a wood processing production line and processing technology. Background Technology

[0002] The general process of wood processing and production is as follows: the original strips are cut into sections of a certain length according to the standard or special specifications of size, shape and quality, and then further processed through peeling, sawing and other processes to obtain square pieces or boards.

[0003] The traditional production method for cutting timber into segments involves: a cutting saw cuts a 2-meter-long piece of timber into four 0.5-meter segments, which are then dropped directly onto the ground from a height of about 2 meters. Simultaneously, manual labor is required below the cutting saw to sort and place the cut segments onto a material cart, thus achieving manual transport and reversal of the segments. Alternatively, a simple conveyor line can be used to directly kick the segments onto the ground using a kicking mechanism. This not only requires additional subsequent structures to reversal the kicked segments but also poses significant safety hazards in the process of directly kicking the segments to the ground.

[0004] The traditional production method for debarking and squaring timber involves setting up three multi-blade saws in conjunction with manual labor. The first multi-blade saw is responsible for sawing the top and bottom edges of the timber, the second multi-blade saw is responsible for sawing the left and right edges of the timber and squaring it, and the third multi-blade saw is responsible for cutting the square timber into sheets. Each multi-blade saw is equipped with at least two workers who work at the feed and discharge ports respectively, responsible for loading and unloading timber, manually reversing the direction of the timber, and recovering the edges. This method is labor-intensive and has significant safety hazards. Alternatively, a rat cage is used to transport and flip the timber. For edge removal, a traditional four-sided clamp is used to feed the timber out, and then the left and right clamps are opened to drop the edges in the left and right directions. This method has limited application scenarios.

[0005] Traditional wood processing technology has complex mechanical structures, low efficiency, low yield, and high cost. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a wood processing production line, which, through the sequential connection of a first sawing mechanism, a first bark separation mechanism, a pushing mechanism, a second sawing mechanism, a second bark separation mechanism, and a third sawing mechanism, can realize the removal of bark, squaring, and slicing of wood, with a high degree of automation, no need for manual assistance, and improved production efficiency and safety.

[0007] The second objective of this invention is to provide a wood processing production process that utilizes a first sawing mechanism, a first bark separation mechanism, a pushing mechanism, a second sawing mechanism, a second bark separation mechanism, and a third sawing mechanism to remove bark from wood, squaring and slicing it, thereby improving the wood processing yield.

[0008] One of the objectives of this invention is achieved through the following technical solution:

[0031] The feeding mechanism includes a material conveyor line, a kicking component, and a dropping hopper. The dropping hopper is located on one side of the material conveyor line, and the kicking component is located on the other side of the material conveyor line.

[0042] S5: The sawn edge skin and the square material pass through the second edge skin separation mechanism together, and the second edge skin separation mechanism separates the edge skin from the square material;

[0043] S6: The square material enters the third sawing mechanism, which slices the square material into sheet material.

[0044] In summary, the present invention has the following technical effects:

[0061] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0062] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0064] See Figures 1-11This invention discloses a wood processing production line, comprising: a first sawing mechanism 10, which saws the bark of wood from the side; a first bark separation mechanism 20, which separates the bark; a pushing mechanism 30, which pushes the wood to change its orientation; a second sawing mechanism 40, which saws the bark of wood from the side and squares the wood to obtain square pieces; a second bark separation mechanism 50, which separates the bark; and a third sawing mechanism 60, which slices the square pieces to obtain sheet pieces; the first sawing mechanism 10, the first bark separation mechanism 20, the pushing mechanism 30, the second sawing mechanism 40, the second bark separation mechanism 50, and the third sawing mechanism 60 are connected sequentially.

[0065] The present invention, by sequentially connecting the first sawing mechanism 10, the first edge bark separation mechanism 20, the pushing mechanism 30, the second sawing mechanism 40, the second edge bark separation mechanism 50 and the third sawing mechanism 60, can realize the removal of edge bark, squaring and slicing of wood. It has a high degree of automation, requires no manual assistance, and improves production efficiency and safety.

[0066] It is understood that the pushing mechanism 30 is used to push down the wood to achieve the reversal of the wood's direction. That is, the present invention utilizes the cooperation of the first sawing mechanism 10, the first edge separation mechanism 20, the pushing mechanism 30, and the second sawing mechanism 40. After the left and right edges of the wood are sawn and separated by the first sawing mechanism 10, the wood rotates 90 degrees around its central axis, and the top and bottom edges of the wood rotate to their left and right directions. The second sawing mechanism 40 then completes the sawing and separation, thereby achieving the sawing of the left and right edges and the top and bottom edges of the wood while the sawing directions of the first sawing mechanism 10 and the second sawing mechanism 40 remain unchanged. This simplifies the mechanical structure and reduces production costs.

[0067] In this embodiment of the invention, the first sawing mechanism 10 includes a first sawing conveyor line 101 and a plurality of first saw blades arranged side by side; the second sawing mechanism 40 includes a second sawing conveyor line 401 and a plurality of second saw blades arranged side by side; the third sawing mechanism 60 includes a third sawing conveyor line 601 and a plurality of third saw blades arranged side by side; the pushing mechanism 30 includes a pushing member 301 and a pushing detection member. When the pushing detection member detects wood, the pushing member 301 pushes down the wood to achieve the reversal of the wood's direction.

[0068] Preferably, the first sawing mechanism 10 includes a first sawing conveyor line 101 and two first saw blades arranged side by side. The two first saw blades are used to saw the outer edges of the wood in the left and right directions. The second sawing mechanism 40 includes a second sawing conveyor line 401 and three second saw blades arranged side by side. Two of the second saw blades are used to saw the outer edges of the wood in the left and right directions after the direction is reversed, and the other second saw blade is used to squarish the wood after the direction is reversed. That is, the wood is sawn and squared in the second sawing mechanism 40 to obtain square wood. The third sawing mechanism 60 includes a third sawing conveyor line 601 and three third saw blades arranged side by side. The three third saw blades are used to slice the square wood to obtain sheet wood.

[0069] It should be noted that the first sawing mechanism 10, the second sawing mechanism 40 and the third sawing mechanism 60 are all existing multi-blade sawing mechanisms. How they achieve sawing of edge skin, sawing of square material and sawing of sliced ​​material are existing technologies and will not be described in detail here.

[0070] Specifically, the push-down detection device is a push switch or a proximity switch, that is, the push-down device 301 is triggered by a gravity sensor or a distance sensor; when the push switch or proximity switch detects the wood passing by, it triggers the push-down device 301 to push the wood down.

[0071] More specifically, the pusher 301 includes a push cylinder and a push wheel. The push wheel is located at the output end of the push cylinder. When the press switch or proximity switch detects the passage of wood, it triggers the output end of the push cylinder to push out, and the push wheel pushes down the wood, thereby realizing the reversal of the wood.

[0072] Of course, in other embodiments, the pusher 301 is driven by a motor. The specific driving method of the pusher 301 depends on the actual situation and is not limited to this.

[0073] In this embodiment of the invention, the first edge bark separation mechanism 20 includes a first edge bark conveying line, and the second edge bark separation mechanism 50 includes a second edge bark conveying line 501; the first sawing conveying line 101 and the second sawing conveying line 401 are arranged along the same central axis, the discharge end of the first sawing conveying line 101 is located close to the feed end of the second sawing conveying line 401, and the width of the discharge end of the first sawing conveying line 101 is greater than the width of the feed end of the second sawing conveying line 401. The width of the feed end of the second sawing conveying line 401 is approximately equal to the width of the wood after one edge bark sawing. The first edge bark conveying line is located on the first sawing conveying line 101. Below the discharge end of 01 and the feed end of the second sawing conveyor line 401; the second sawing conveyor line 401 and the third sawing conveyor line 601 are arranged along the same central axis, the discharge end of the second sawing conveyor line 401 is close to the feed end of the third sawing conveyor line 601, and the width of the discharge end of the second sawing conveyor line 401 is greater than the width of the feed end of the third sawing conveyor line 601. The width of the feed end of the third sawing conveyor line 601 is approximately equal to the width of the wood after secondary edge sawing. The second edge conveyor line 501 is located below the discharge end of the second sawing conveyor line 401 and the feed end of the third sawing conveyor line 601.

[0074] Understandably, after the wood undergoes one edge sawing by the first sawing mechanism 10, the edge cut off is still conveyed along with the wood on the first sawing conveyor line 101. To achieve separation of the edge cut from the wood, the present invention sets the width of the feed end of the second sawing conveyor line 401 to be smaller than the width of the discharge end of the first sawing conveyor line 101. The width of the feed end of the second sawing conveyor line 401 is approximately equal to the width of the wood after the first edge sawing. When the edge cut off is conveyed along with the wood from the first sawing conveyor line 101 to the second sawing conveyor line 401, due to the limited width of the feed end of the second sawing conveyor line 401, the edge cut naturally falls from both sides of the feed end of the second sawing conveyor line 401 onto the first edge cut conveyor line below. The first edge cut conveyor line conveys the edge cut off to the recycling mechanism, preventing the edge cut off from entering the second sawing mechanism 40 and affecting the positioning and sawing of the wood.

[0075] Specifically, in order to ensure that the sapwood falls onto the first sapwood conveyor line instead of falling during the conveying process on the first sawing conveyor line 101, the overall width of the first sawing conveyor line 101 is greater than the diameter of the wood that has not undergone sapwood sawing, thereby facilitating the conveying of the sapwood on the first sawing conveyor line 101.

[0076] Similarly, after the wood undergoes secondary edge sawing via the second sawing mechanism 40, the edge cut off is still conveyed along with the wood on the second sawing conveyor line 401. To separate the edge from the wood, the present invention sets the width of the feed end of the third sawing conveyor line 601 to be smaller than the width of the discharge end of the second sawing conveyor line 401. The width of the feed end of the third sawing conveyor line 601 is approximately equal to the width of the wood after secondary edge sawing. When the cut edge is conveyed along with the wood from the second sawing conveyor line 401 to the third sawing conveyor line 601, due to the limited width of the feed end of the third sawing conveyor line 601, the edge naturally falls from both sides of the feed end of the third sawing conveyor line 601 onto the second edge conveyor line 501 located below. The second edge conveyor line 501 conveys the edge that has fallen onto it to the recycling mechanism, preventing the edge cut off from entering the third sawing mechanism 60 and affecting the positioning and sawing of the square piece.

[0077] Specifically, in order to ensure that the sapwood falls onto the second sapwood conveyor line 501 instead of falling off during transport on the second sawing conveyor line 401, the overall width of the rear section of the second sawing conveyor line 401 is greater than the diameter of the wood that has not undergone sapwood sawing, thereby facilitating the transport of the sapwood on the second sawing conveyor line 401. The feed end of the second sawing conveyor line 401 is located at the front section of the second sawing conveyor line 401.

[0078] More specifically, see Figure 11 Assuming the wood is round, the diameter of the wood before the bark is cut is... The width of the wood after one edge sawing is The width of the wood in another direction after the second edge sawing is also... Preferred, Timber yield , ,in this way, Traditional wood processing equipment has a low yield, typically only 50% or less. This invention improves the yield of wood processing.

[0079] In this embodiment of the invention, the wood processing production line includes at least one centering mechanism 70, which is located at the feed inlet of the second sawing mechanism 40. The centering mechanism 70 includes a centering component 701 and a centering detection component 702. The two centering components 701 are symmetrically arranged on the left and right sides of the feed end of the second sawing conveyor line 401. When the centering detection component 702 detects wood, the two centering components 701 simultaneously push the wood closer to the central axis of the second sawing conveyor line 401.

[0080] Preferably, the wood processing production line includes two sequentially arranged central mechanisms 70.

[0081] Specifically, the centering detection element 702 is a push switch or a proximity switch, that is, the centering element 701 is triggered by a gravity sensor or a distance sensor; when the push switch or proximity switch detects the wood passing by, it triggers the centering element 701 to move the wood closer to the central axis of the second sawing conveyor line 401.

[0082] More specifically, the centering component 701 includes a centering motor, a centering swing arm, and a centering wheel. The centering wheel is located at one end of the centering swing arm, and the output end of the centering motor is located at the other end of the centering swing arm. When the press switch or proximity switch detects the passage of wood, it triggers the output end of the centering motor to rotate, and the centering swing arm swings to push the wood closer to the central axis of the second sawing conveyor line 401, thereby achieving the centering of the wood. The centering of the wood is beneficial to the accuracy of subsequent sawing of the wood. Thus, two or three centering mechanisms 70 can be set to center the wood, thereby improving the sawing accuracy. The number of centering mechanisms 70 can be determined according to the length of the feed end of the second sawing conveyor line 401.

[0083] Of course, in other embodiments, the centering component 701 is driven by a cylinder, which directly pushes the wood closer to the central axis of the second sawing conveyor line 401 through the centering wheel. The specific driving method of the pushing component 301 depends on the actual situation and is not limited to this.

[0084] In this embodiment of the invention, the third sawing conveyor line 601 includes a first differential conveyor chain 6011, a second differential conveyor chain 6012, and a tilting wheel 6013. The first differential conveyor chain 6011 and the second differential conveyor chain 6012 are arranged side by side, and the conveying speed of the first differential conveyor chain 6011 is less than the conveying speed of the second differential conveyor chain 6012. The feed inlet of the third sawing mechanism 60 is located close to the discharge end of the second differential conveyor chain 6012. The tilting wheel 6013 is inclinedly arranged on the first differential conveyor chain 6011 and the second differential conveyor chain 6012. The tilting wheel 6013 is used to flip the square material on the first differential conveyor chain 6011 and guide it onto the second differential conveyor chain 6012.

[0085] Specifically, the purpose of setting up the first differential speed conveyor chain 6011, the second differential speed conveyor chain 6012, and the tilting wheel 6013 is to enable the two square pieces cut by the second sawing mechanism 40 to enter the third sawing mechanism 60 in a front-to-back order for sawing. This avoids the situation where two square pieces enter the third sawing mechanism 60 at the same time, and facilitates the positioning and sawing of a single square piece in the third sawing mechanism 60, thereby improving the accuracy of square piece sawing.

[0086] To better ensure that the two square blocks enter the third sawing mechanism 60 in a sequential order, the conveying speed of the second differential conveyor chain 6012 is controlled so that the two square blocks are conveyed one after the other, avoiding interference between them. In addition, multiple parallel second differential conveyor chains 6012 are set up, in conjunction with tilting tilting wheels 6013, to facilitate the diversion of square blocks on the first differential conveyor chain 6011 to the second differential conveyor chain 6012. Finally, all the square blocks enter the third sawing mechanism 60 through the feed port.

[0087] More specifically, the tilting roller 6013 is rotatably mounted above the third sawing conveyor line 601 via a bracket. Thus, when the square material is conveyed on the third sawing conveyor line 601, the upper part of the square material touches the tilting roller 6013, thereby flipping the square material. The flipping of the square material results in the long side of the square material facing upward, which is beneficial for the third sawing mechanism 60 to saw the square material into a suitable number of sheets.

[0088] In this embodiment of the invention, the wood processing production line includes a side-adjusting mechanism 80, which is disposed at the feed inlet of the third sawing mechanism 60. The side-adjusting mechanism 80 includes a positioning component 801, a side-adjusting component 802, and a side-adjusting detection component. The positioning component 801 and the side-adjusting component 802 are respectively disposed on both sides of the second differential speed conveyor chain 6012. When the side-adjusting detection component detects the square material, the side-adjusting component 802 pushes the square material closer to the positioning component 801.

[0089] Specifically, the edge detection component is a push switch or a proximity switch, that is, the edge detection component 802 is triggered by a gravity sensor or a distance sensor; when the push switch or proximity switch detects the wood passing by, it triggers the edge detection component 802 to push the wood closer to the positioning component 801 to achieve edge detection.

[0090] More specifically, the edge-keeping component 802 includes an edge-keeping cylinder and an edge-keeping wheel. The edge-keeping wheel is located at the output end of the edge-keeping cylinder. When the press switch or proximity switch detects the passage of wood, it triggers the output end of the edge-keeping cylinder to push out, and the edge-keeping wheel pushes the positioning component 801 to achieve edge-keeping.

[0091] Of course, in other embodiments, the edge member 802 is driven by a motor. The specific driving method of the edge member 802 depends on the actual situation and is not limited to this.

[0092] See Figures 7-10In this embodiment of the invention, the wood processing production line includes a feeding mechanism 90, which is located at the feed inlet of the first sawing mechanism and connected to the first sawing mechanism. The feeding mechanism 90 includes an incoming material conveyor line 901, a kicking component 902, and a dropping hopper 903. The dropping hopper 903 is located on one side of the incoming material conveyor line 901, and the kicking component 902 is located on the other side of the incoming material conveyor line 901. The kicking component 902 is used to kick the wood on the incoming material conveyor line 901 to the dropping hopper 903. The feed inlet of the dropping hopper 903 is larger than the discharge outlet of the dropping hopper 903.

[0093] Specifically, the kicking component 902 includes a kicking motor and a kicking swing arm. The rotation of the kicking motor drives the kicking swing arm to rotate, thereby kicking the wood on the material conveyor line 901 into the dropping hopper 903.

[0094] Understandably, the kicking lever only needs to swing at one angle to kick the logs on the incoming material conveyor line 901 to the dropping hopper 903 when kicking. The kicking drive motor is a forward and reverse motor.

[0095] Of course, in other embodiments, the kicking component 902 is driven by a cylinder. The specific driving method of the kicking component 902 depends on the actual situation and is not limited to this.

[0096] The feed inlet of the hopper 903 is larger than the discharge outlet of the hopper 903. The diameter of the feed inlet of the hopper 903 is larger than the length of the wood, and the discharge outlet of the hopper 903 is smaller than the length of the wood. In addition, the discharge outlet of the hopper 903 is slightly larger than the diameter of the wood. In this way, the forward direction of the wood falling into the hopper 903 is changed by 90 degrees, and the hopper 903 can prevent the wood from getting stuck in the channel.

[0097] More specifically, the incoming material conveyor line 901 is equipped with a kick detection device, which is a push switch, a proximity switch, or an infrared probe. That is, the kick device 902 is triggered by a gravity sensor, a distance sensor, or an infrared probe. When wood of a predetermined weight or a predetermined length passes through, the kick motor rotates, driving the kick swing arm to rotate, thereby kicking the wood on the incoming material conveyor line 901 into the discharge hopper 903, thus achieving the screening of wood.

[0098] In this embodiment of the invention, the feeding mechanism 90 includes a discharge conveyor line 904, a storage bin 905, and a pusher 906. The discharge conveyor line 904 is located at the discharge port of the discharge hopper 903, the storage bin 905 is located on one side of the discharge conveyor line 904, and the pusher 906 is located on the other side of the discharge conveyor line 904. The pusher 906 is used to push the wood on the discharge conveyor line 904 to the storage bin 905.

[0099] Specifically, the pusher 906 includes a pusher cylinder that extends to push the timber on the unloading conveyor line 904 to the storage bin 905.

[0100] Of course, in other embodiments, the pusher 906 is driven by a motor. The specific driving method of the pusher 906 depends on the actual situation and is not limited to this.

[0101] Specifically, a push detection device is installed on the material feeding conveyor line 904. The push detection device is a push switch or a proximity switch. That is, the push device 906 is triggered by a gravity sensor or a distance sensor. When wood is detected, the push cylinder extends to push the wood on the material feeding conveyor line 904 to the storage bin 905.

[0102] More specifically, the storage bin 905 includes a storage conveyor line, on which several partitions are spaced apart along its length. The gap between two adjacent partitions forms a storage space for a single piece of wood. When wood needs to be conveyed to the first sawing conveyor line 101, the storage conveyor line can convey the wood forward by the distance of one piece of wood.

[0103] In this embodiment of the invention, the wood processing production line includes a discharge mechanism 100. The discharge port of the first sawing mechanism 10 and the discharge port of the second sawing mechanism 40 are both provided with discharge mechanisms 100. The discharge mechanism 100 includes discharge pressure rollers 1001. Multiple discharge pressure rollers 1001 are rotatably arranged above the discharge port of the first sawing mechanism 10 and above the discharge port of the second sawing mechanism 40.

[0104] Thus, when the discharge roller 1001 presses the wood tightly and assists in conveying the wood forward, it prevents the wood from falling off along with the edge bark when the edge bark separates from the wood.

[0105] In this embodiment of the invention, the first sawing conveyor line 101, the first edge bark conveyor line, the second sawing conveyor line 401, the second edge bark conveyor line 501, the third sawing conveyor line 601, the incoming material conveyor line 901, and the unloading conveyor line 904 are all conveyor chains, which facilitate the transport of wood. Of course, in other embodiments, the first sawing conveyor line 101, the first edge bark conveyor line, the second sawing conveyor line 401, the second edge bark conveyor line 501, the third sawing conveyor line 601, the incoming material conveyor line 901, and the unloading conveyor line 904 are all conveyor belts, and their specific conveying type depends on the actual situation and is not limited to this.

[0106] See Figures 1-11 This invention discloses a wood processing production process, which uses the above-mentioned wood processing production line and includes the following steps:

[0107] S1: The wood enters the first sawing mechanism 10, and the first sawing mechanism 10 cuts the edge bark of the wood from the side;

[0108] S2: The sawn bark and wood pass together through the first bark separation mechanism 20, which separates the bark from the wood.

[0109] S3: The timber is pushed down by the pushing mechanism 30, which reverses the direction of the timber.

[0110] S4: The wood after reversing direction enters the second sawing mechanism 40. The second sawing mechanism 40 saws the edge of the wood from the side and squares the wood to obtain square material.

[0111] S5: The sawn edge skin and the square material pass through the second edge skin separation mechanism 50 together, and the second edge skin separation mechanism 50 separates the edge skin from the square material;

[0112] S6: The square material enters the third sawing mechanism 60, which slices the square material to obtain sheet material.

[0113] The present invention utilizes a first sawing mechanism 10, a first edge-bark separation mechanism 20, a pushing mechanism 30, a second sawing mechanism 40, a second edge-bark separation mechanism 50, and a third sawing mechanism 60 to remove the edge bark, squaring, and slicing of wood, thereby improving the yield of wood processing.

[0114] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
