Description

Technical Field

[0001] The utility model relates to the field of wood processing and production, in particular to a wood processing production line. Background Art

[0002] The general process of wood processing and production is: cut the original strips into wood sections of a certain length according to standard or special regulations on size, shape, quality, and continue to obtain square materials or boards through processes such as peeling and sawing.

[0003] The traditional production model of sawing wood into wood segments is: the cutting saw cuts the 2-meter-long wood into four small segments of 0.5 meters, and then smashes it directly to the ground from a height of about 2 meters. At the same time, it is necessary to manually classify the sawn wood segments and place them on the material cart under the cutting saw, so as to realize the manual transportation and manual reversing of the wood segments; or a kicking mechanism is directly set up after a simple conveyor line to kick the wood segments to the ground. Not only does it need to set up a subsequent structure to reverse the kicked wood segments, but there are also great safety hazards in the process of kicking the wood segments directly to the ground.

[0004] The traditional production model for wood peeling and sawing and squaring is to set up three multi-blade saws and cooperate with manual work. The first multi-blade saw is responsible for sawing the upper and lower bark of the wood, the second multi-blade saw is responsible for sawing the left and right bark of the wood and squaring it, and the third multi-blade saw is responsible for cutting the square material into sheets. Each multi-blade saw is equipped with at least two workers who work at the feed inlet and discharge outlet of the multi-blade saw respectively, and are responsible for loading and unloading wood, manually changing the direction of wood and recovering the bark, etc. The labor intensity is high and there are great safety hazards. Alternatively, the wood is transported and flipped by a squirrel cage flipping method. For bark removal, the traditional four-sided clamping is used to send it out, and then the left and right clamps are opened to drop the bark in the left and right directions, which limits the usage scenarios.

[0005] The traditional wood processing production process has a complex mechanical structure and low efficiency, and the yield rate of traditional wood processing equipment is low and the cost is high. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0054] See also Figure 1-Figure 11 The utility model discloses a wood processing production line, comprising: a first sawing mechanism 10, the first sawing mechanism 10 saws the edge of the wood from the side; a first edge separation mechanism 20, the first edge separation mechanism 20 is used to separate the edge; a push-down mechanism 30, the push-down mechanism 30 is used to push the wood to achieve the change of direction of the wood; a second sawing mechanism 40, the second sawing mechanism 40 saws the edge of the wood from the side, and the second sawing mechanism 40 squares the wood to obtain square materials; a second edge separation mechanism 50, the second edge separation mechanism 50 is used to separate the edge; a third sawing mechanism 60, the third sawing mechanism 60 is used to slice the square material to obtain sheet materials; the first sawing mechanism 10, the first edge separation mechanism 20, the push-down mechanism 30, the second sawing mechanism 40, the second edge separation mechanism 50 and the third sawing mechanism 60 are connected in sequence.

[0055] The utility model can realize the edge bark removal, squaring and slicing of wood by sequentially connecting the first sawing mechanism 10, the first edge skin separation mechanism 20, the pushing mechanism 30, the second sawing mechanism 40, the second edge skin separation mechanism 50 and the third sawing mechanism 60, with a high degree of automation, without the need for manual assistance, thereby improving production efficiency and safety.

[0056] It can be understood that the pushing mechanism 30 is used to push down the wood so as to achieve the reversal of the wood, that is, the utility model utilizes the first sawing mechanism 10, the first edge skin separation mechanism 20, the pushing mechanism 30, and the second sawing mechanism 40 to cooperate with each other. After the left and right edges of the wood are sawed and separated by the first sawing mechanism 10, the wood is rotated 90 degrees around its central axis, and the upper and lower edges of the wood are rotated to its left and right directions, and are sawed and separated by the second sawing mechanism 40, thereby achieving the sawing of the left and right edges of the wood and the upper and lower edges of the wood without changing the sawing directions of the first sawing mechanism 10 and the second sawing mechanism 40, thereby simplifying the mechanical structure and reducing production costs.

[0057] In an embodiment of the utility model, the first sawing mechanism 10 includes a first sawing conveyor line 101 and a plurality of first saw blades, which are arranged side by side; the second sawing mechanism 40 includes a second sawing conveyor line 401 and a plurality of second saw blades, which are arranged side by side; the third sawing mechanism 60 includes a third sawing conveyor line 601 and a plurality of third saw blades, which are arranged side by side; the pushing mechanism 30 includes a pushing member 301 and a pushing detection member, and when the pushing detection member detects wood, the pushing member 301 pushes the wood to achieve the reversal of the wood.

[0058] Preferably, the first sawing mechanism 10 includes a first sawing conveyor line 101 and two first saw blades, the two first saw blades are arranged side by side, and the two first saw blades are used to saw the left and right edges of the wood; the second sawing mechanism 40 includes a second sawing conveyor line 401 and three second saw blades, the three second saw blades are arranged side by side, two of the second saw blades are used to saw the left and right edges of the wood after the switch, and the other second saw blade is used to square the wood after the switch, that is, the wood is sawn and squared in the second sawing mechanism 40 to obtain square materials; the third sawing mechanism 60 includes a third sawing conveyor line 601 and three third saw blades, the three third saw blades are arranged side by side, and the three third saw blades are used to slice square materials to obtain sheet materials.

[0059] 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 saw mechanisms, and how to saw edge skin, how to saw square materials and how to saw sliced ​​materials are existing technologies and will not be repeated here.

[0060] Specifically, the knocking detection member is a push switch or a proximity switch, that is, a gravity sensor or a distance sensor is used to trigger the knocking member 301; when the push switch or the proximity switch detects that wood has passed, the knocking member 301 is triggered to push the wood down.

[0061] More specifically, the pushing member 301 includes a pushing cylinder and a pushing wheel. The pushing wheel is arranged at the output end of the pushing cylinder. When the pressing switch or the proximity switch detects that the wood passes through, the output end of the pushing cylinder is triggered to push out, and the pushing wheel pushes down the wood, thereby realizing the reversal of the wood.

[0062] Of course, in other embodiments, the pushing member 301 is driven by a motor, and the specific driving method of the pushing member 301 is determined according to actual conditions and is not limited thereto.

[0063] In the embodiment of the utility model, the first edge skin separation mechanism 20 includes a first edge skin conveyor line, and the second edge skin separation mechanism 50 includes a second edge skin conveyor line 501; the first sawing conveyor line 101 and the second sawing conveyor line 401 are arranged along the same central axis, the discharge end of the first sawing conveyor line 101 is arranged close to the feed end of the second sawing conveyor line 401, and the width of the discharge end of the first sawing conveyor line 101 is greater than the width of the feed end of the second sawing conveyor line 401, and the width of the feed end of the second sawing conveyor line 401 is approximately equal to the width of the wood after one edge skin sawing, and the first edge skin conveyor line is arranged on the first sawing conveyor line 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 arranged 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 the second edge skin sawing, and the second edge skin conveyor line 501 is arranged at the discharge end of the second sawing conveyor line 401 and below the feed end of the third sawing conveyor line 601.

[0064] It can be understood that after the wood has completed one edge sawing through the first sawing mechanism 10, the edge sawed off is still conveyed together with the wood on the first sawing conveyor line 101. In order to separate the edge bark from the wood, the utility model arranges 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, and the width of the feed end of the second sawing conveyor line 401 is roughly equal to the width of the wood after one edge sawing. When the edge bark cut off is conveyed from the first sawing conveyor line 101 to the second sawing conveyor line 401 together with the wood, due to the width limitation of the feed end of the second sawing conveyor line 401, the edge bark naturally falls from both sides of the feed end of the second sawing conveyor line 401 to the first edge bark conveyor line located below, and the first edge bark conveyor line conveys the edge bark that falls on it to the recovery mechanism, so as to prevent the edge bark cut off from entering the second sawing mechanism 40 and affecting the positioning and sawing of the wood.

[0065] Specifically, in order to allow the edge skin to fall onto the first edge skin conveyor line instead of falling during transportation 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 been sawn, thereby facilitating the transportation of the edge skin on the first sawing conveyor line 101.

[0066] Similarly, after the wood has completed the secondary edge sawing through the second sawing mechanism 40, the secondary edge sawing is still conveyed together with the wood on the second sawing conveyor line 401. In order to separate the edge bark from the wood, the utility model arranges 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 roughly equal to the width of the wood after the secondary edge bark sawing. When the sawn edge bark is conveyed from the second sawing conveyor line 401 to the third sawing conveyor line 601 together with the wood, due to the width limitation of the feed end of the third sawing conveyor line 601, the edge bark naturally falls from both sides of the feed end of the third sawing conveyor line 601 to the second edge bark conveyor line 501 located below. The second edge bark conveyor line 501 conveys the edge bark that falls on it to the recovery mechanism, thereby preventing the secondary sawn edge bark from entering the third sawing mechanism 60 and affecting the positioning and sawing of the square materials.

[0067] Specifically, in order to ensure that the edge skin can fall onto the second edge skin conveyor line 501 instead of falling during transportation 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 been sawn by the edge skin, thereby facilitating the transportation of the edge skin on the second sawing conveyor line 401. The feeding end of the second sawing conveyor line 401 is located at the front section of the second sawing conveyor line 401.

[0068] More specifically, see Fig.11 Assuming that the wood is a round log, the diameter of the wood before the edge sawing is 2a, the width of the wood after the first edge sawing is b, and the width of the wood after the second edge sawing is also b; preferably, The wood yield is c, Thus, c=0.64, the yield rate of conventional wood processing equipment is relatively low, the yield rate of conventional wood processing equipment is only 50% or lower than 50%, and the utility model improves the yield rate of wood processing.

[0069] In an embodiment of the utility model, the wood processing production line includes at least one centering mechanism 70, which is arranged at the feed port of the second sawing mechanism 40; the centering mechanism 70 includes a centering piece 701 and a centering detection piece 702, and the two centering pieces 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 piece 702 detects the wood, the two centering pieces 701 simultaneously push the wood close to the center axis of the second sawing conveyor line 401.

[0070] Preferably, the wood processing production line comprises two centering mechanisms 70 arranged in sequence.

[0071] Specifically, the centering detection member 702 is a push switch or a proximity switch, that is, the centering member 701 is triggered by a gravity sensor or a distance sensor; when the push switch or the proximity switch detects that the wood passes through, the centering member 701 is triggered to push the wood close to the central axis of the second sawing conveyor line 401.

[0072] More specifically, the centering member 701 includes a centering motor, a centering rocker and a centering wheel. The centering wheel is arranged at one end of the centering rocker, and the output end of the centering motor is arranged at the other end of the centering rocker. When the pressing switch or the proximity switch detects that the wood passes through, the output end of the centering motor is triggered to rotate, and the centering rocker swings to push the wood close to the central axis of the second sawing conveyor line 401, thereby achieving the centering of the wood; the centering setting of the wood is beneficial to the subsequent sawing accuracy of the wood. In this way, 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 feeding end of the second sawing conveyor line 401.

[0073] Of course, in other embodiments, the centering member 701 is driven by a cylinder, and the cylinder directly pushes the wood close to the central axis of the second sawing conveyor line 401 through the centering wheel. The specific driving method of the knocking member 301 depends on the actual situation and is not limited to this.

[0074] In an embodiment of the utility model, the third sawing conveyor line 601 includes a first differential conveying chain 6011, a second differential conveying chain 6012 and a tipping wheel 6013. The first differential conveying chain 6011 and the second differential conveying chain 6012 are arranged side by side, and the conveying speed of the first differential conveying chain 6011 is lower than the conveying speed of the second differential conveying chain 6012. The feed port of the third sawing mechanism 60 is arranged close to the discharge end of the second differential conveying chain 6012; the tipping wheel 6013 is obliquely arranged on the first differential conveying chain 6011 and the second differential conveying chain 6012, and the tipping wheel 6013 is used to turn over the square material on the first differential conveying chain 6011 and guide it onto the second differential conveying chain 6012.

[0075] Specifically, the purpose of setting the first differential conveying chain 6011, the second differential conveying chain 6012 and the tipping wheel 6013 is to ensure that the two square materials obtained by the second sawing mechanism 40 can be arranged in a front-to-back order and enter the third sawing mechanism 60 for sawing. In this way, the situation where two square materials enter the third sawing mechanism 60 at the same time is avoided, which facilitates the positioning and sawing of a single square material in the third sawing mechanism 60, thereby improving the accuracy of sawing the square materials.

[0076] In order to better realize that the two square materials are arranged in a front-to-back order and enter the third sawing mechanism 60, the conveying speed of the second differential conveying chain 6012 is controlled so that the two square materials are conveyed one after the other to avoid interference between the square materials; and a plurality of second differential conveying chains 6012 arranged in parallel are arranged, and cooperate with the tilted tipping wheels 6013 to facilitate the square materials on the first differential conveying chain 6011 to change direction to the second differential conveying chain 6012, and finally all the square materials enter the third sawing mechanism 60 through the feed port of the third sawing mechanism 60.

[0077] More specifically, the tipping wheel 6013 is rotatably arranged above the third sawing conveyor line 601 through a bracket. In this way, when the square material is conveyed on the third sawing conveyor line 601, the upper part of the square material touches the tipping wheel 6013, thereby realizing the turning over of the square material. The turning over of the square material makes the long side of the square material face upward, which is beneficial for the third sawing mechanism 60 to saw the square material into a suitable number of sheets.

[0078] In an embodiment of the utility model, the wood processing production line includes an edge-pushing mechanism 80, which is arranged at the feed port of the third sawing mechanism 60; the edge-pushing mechanism 80 includes a positioning member 801, an edge-pushing member 802 and an edge-pushing detection member, and the positioning member 801 and the edge-pushing member 802 are respectively arranged on both sides of the second differential conveying chain 6012. When the edge-pushing detection member detects the square material, the edge-pushing member 802 pushes the square material close to the positioning member 801.

[0079] Specifically, the edge detection member is a push switch or a proximity switch, that is, the edge member 802 is triggered by using a gravity sensor or a distance sensor; when the push switch or the proximity switch detects that the wood passes through, the edge member 802 is triggered to push the wood close to the positioning member 801 to achieve the edge.

[0080] More specifically, the edge member 802 includes an edge cylinder and an edge wheel. The edge wheel is arranged at the output end of the edge cylinder. When the pressing switch or the proximity switch detects that the wood passes through, the output end of the edge cylinder is triggered to be pushed out, and the edge wheel pushes the positioning member 801 to achieve the edge.

[0081] Of course, in other embodiments, the side member 802 is driven by a motor, and the specific driving method of the side member 802 depends on the actual situation and is not limited to this.

[0082] See also Figure 7-Figure 10 In an embodiment of the utility model, the wood processing production line includes a feeding mechanism 90, which is arranged at the feed port of the first saw blade mechanism, and the feeding mechanism 90 is connected to the first saw blade mechanism; the feeding mechanism 90 includes an incoming material conveying line 901, a kicking piece 902 and a drop hopper 903, the drop hopper 903 is arranged on one side of the incoming material conveying line 901, and the kicking piece 902 is arranged on the other side of the incoming material conveying line 901, and the kicking piece 902 is used to kick the wood on the incoming material conveying line 901 to the drop hopper 903; the feed port of the drop hopper 903 is larger than the discharge port of the drop hopper 903.

[0083] Specifically, the kicking member 902 includes a kicking motor and a kicking swing rod. The kicking motor rotates to drive the kicking swing rod to rotate, thereby kicking the wood on the incoming material conveying line 901 to the drop hopper 903.

[0084] It can be understood that the kicking swing arm only needs to swing an angle when kicking the material to kick the wood section on the incoming material conveying line 901 to the drop hopper 903, and the kicking drive motor adopts a forward and reverse motor.

[0085] Of course, in other embodiments, the kicking member 902 is driven by a cylinder, and the specific driving method of the kicking member 902 is determined according to actual conditions and is not limited to this.

[0086] The feed port of the drop hopper 903 is larger than the discharge port of the drop hopper 903, the diameter of the feed port of the drop hopper 903 is larger than the length of the wood, the discharge port of the drop hopper 903 is smaller than the length of the wood, and the discharge port of the drop hopper 903 is slightly larger than the diameter of the wood. In this way, the forward direction of the wood falling into the drop hopper 903 is turned 90 degrees, and the drop hopper 903 can prevent the wood from getting stuck in the channel.

[0087] More specifically, a kicking detection component is provided on the incoming material conveyor line 901, and the kicking detection component is a push switch, a proximity switch or an infrared probe, that is, a gravity sensor, a distance sensor or an infrared probe is used to trigger the kicking component 902.
