Description

Technical Field

[0001] This invention relates to the field of wood processing, and more particularly to a wood processing apparatus for pulp production. Background Technology

[0002] In pulp production, wood debarking is the first step in the preparation workshop. Since tree bark not only lacks the cellulose fibers needed for papermaking but also contains a large amount of pigments, impurities, and high ash content, failure to remove it will reduce the brightness and strength of the pulp, increase chemical consumption, and even clog equipment. Therefore, thorough bark removal is crucial for producing clean, high-quality wood pulp.

[0003] When peeling wood, the bark often has high tensile strength, and when the wood is rotated and rubbed or cut with a knife, the bark tends to stick together in large pieces, making it difficult to peel off completely. At the same time, when peeling wood with a roller peeling knife, it is necessary to overcome great friction, which not only increases the energy consumption of the equipment and the wear of the knife, but also makes it very easy to cut deep into and damage the internal wood fibers (i.e., damage the cambium) due to uneven force. If the cambium is damaged during the peeling process, it is easy to cause rot or cavities on the surface of the wood, which will directly reduce the strength and grade of the final wood. Summary of the Invention

[0004] In order to overcome the disadvantage that when peeling wood, the bark has high tensile strength and tends to stick together in large pieces when the wood is rotated and rubbed or cut with a knife, making it difficult to completely remove the bark, the present invention provides a wood processing device for pulp production.

[0006] Furthermore, the drive assembly includes a linear electric guide rail, a moving block, and an electric push rod; the worktable is connected to the linear electric guide rail; the moving block is slidably connected to the linear electric guide rail; the moving block is fixedly connected to the electric push rod, and the telescopic end of the electric push rod is fixedly connected to the connecting frame.

[0007] Furthermore, it also includes retaining rings and conveying pipes; the connecting frame is rotatably connected to two retaining rings, and the outer side of the retaining rings is arc-shaped, with the electric cutter located between the two retaining rings; the connecting frame is fixedly connected to two conveying pipes, and the conveying pipes are fixedly connected to the corresponding retaining rings.

[0008] Furthermore, it also includes protective plates and brushes; the worktable is fixed with two arc-shaped protective plates, and the protective plates are located outside the corresponding electric peeling rollers, and the protective plates are slidably connected to the corresponding support rings; each protective plate has several brushes connected to its inner lower part.

[0009] Furthermore, the protective plate is detachably connected to the brush bristles.

[0010] With the above-described structure, the present invention facilitates the manual disassembly and replacement of the brush bristles on a regular basis.

[0011] Furthermore, the spraying assembly includes a semi-circular ring, a connecting pipe, and a nozzle; a hollow semi-circular ring is fixedly connected to the connecting frame; a cavity is opened inside the semi-circular ring; the semi-circular ring is connected to the connecting pipe; and several nozzles are connected to the semi-circular ring, with the nozzles communicating with the cavity.

[0012] Furthermore, it also includes a scraper ring; the semi-circular ring is fixed with the scraper ring.

[0013] Furthermore, a sealing gasket is provided between the semi-circular ring and the partition.

[0014] By adopting the above structure, the present invention enhances the sealing performance between the semi-circular ring and the partition.

[0015] Furthermore, it also includes arc-shaped guide rails, electric sliders, partitions, hollow tubes, nozzles, collection boxes, and electric rotating plates; the worktable is fixedly connected to two arc-shaped guide rails; each arc-shaped guide rail is slidably connected to an electric slider, and the two electric sliders are together fixedly connected to a linear electric guide rail; a partition is fixedly connected to a semi-circular ring, and the partition divides the interior of the semi-circular ring into a hollow cavity and an annular cavity; a hollow tube is fixedly connected to the semi-circular ring, and the hollow tube communicates with the annular cavity; several nozzles are connected to the annular cavity; a collection box is slidably connected to the worktable, and the collection box can be inserted into a rectangular groove; two mounting plates are rotatably connected to two electric rotating plates, and the electric rotating plates are located below the corresponding electric peeling rollers.

[0016] Furthermore, the inner side of the electric rotating plate is roughened.

[0017] By adopting the above structure, the present invention increases the friction between the electric rotating plate and the wood body, thereby improving the fixing effect of the electric rotating plate on the wood body.

[0018] The present invention has the following advantages: By pre-cutting multiple slits in the bark on the surface of the wood, the present invention destroys the waterproof barrier of the bark, accelerates the penetration of water and softening of the bark, and greatly reduces the bonding force between the bark and the wood after the bark absorbs water and softens, making the subsequent mechanical peeling by the electric peeling roller extremely easy. At the same time, it provides physical break points on the surface of the bark, allowing the bark to easily break and peel off along these pre-set gaps, improving the cleanliness and efficiency of peeling, and significantly reducing mechanical cutting resistance, thus protecting the woody part at the bottom of the wood.

[0019] Simultaneously, as the electric cutter moves along the surface of the wood to cut the bark, the connecting frame drives the retaining ring to move, causing the outer arc of the retaining ring to engage with the cut in the bark. This process then pries open the cut in the bark. Next, the external liquid pump is activated to deliver surfactant liquid (wetting agent) into the delivery pipe, allowing the surfactant liquid to penetrate into the cut in the bark and improving the wetting efficiency of the surfactant liquid on the bark.

[0020] Furthermore, after the wood body is debarked, an external pump is controlled to deliver end-sealing agent liquid into the annular cavity through a hollow tube, so that the liquid is sprayed from the nozzle to the end of the wood body. The linear electric guide rail is controlled to move the moving block, which drives the electric push rod and its connected components to move horizontally, thereby spraying the end-sealing agent liquid onto the other end of the wood body. This ensures that both ends of the wood body are covered with end-sealing agent after debarking, slowing down the rate of moisture loss and allowing the wood to dry evenly and slowly.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: A wood processing apparatus for pulp production, such as Figures 1-8 As shown, the device includes a worktable 1, a mounting plate 101, an electric peeling roller 102, and an electric connecting block 1016. A rectangular groove 11 is provided below the worktable 1. Two mounting plates 101 are fixedly connected to the worktable 1. Each of the two mounting plates 101 is slidably connected to an electric connecting block 1016. The two mounting plates 101 are rotatably connected to an electric peeling roller 102, and the two electric connecting blocks 1016 are rotatably connected to another electric peeling roller 102. It also includes a support ring 103. Each electric peeling roller 102 is slidably connected to two electric connecting blocks 1016 via a long key. Each mounting plate 101 has a support ring 103; each mounting plate 101 has a cylinder 104 fixedly connected to it; two electric connecting blocks 1016 are fixedly connected to another cylinder 104, and the telescopic end of the cylinder 104 is rotatably connected to the corresponding support ring 103; a drive assembly for moving the electric cutter 106 is connected to the workbench 1; a connecting frame 105 is connected to the drive assembly; the electric cutter 106 is rotatably connected to the connecting frame 105; a spraying assembly for spraying surfactant liquid onto the surface of the wood body 2 is also connected to the connecting frame 105.

[0025] The drive assembly includes a linear electric guide rail 1011, a moving block 1012, and an electric push rod 1013; the worktable 1 is connected to the linear electric guide rail 1011; the linear electric guide rail 1011 is slidably connected to the moving block 1012; the moving block 1012 is bolted to the electric push rod 1013, and the telescopic end of the electric push rod 1013 is fixedly connected to the connecting frame 105.

[0026] It also includes a retaining ring 107 and a conveying pipe 108; the connecting frame 105 is rotatably connected to two retaining rings 107, and the outer side of the retaining rings 107 is arc-shaped, and the electric cutter 106 is located between the two retaining rings 107; the connecting frame 105 is fixedly connected to two conveying pipes 108, and the conveying pipes 108 are fixedly connected to the corresponding retaining rings 107.

[0027] It also includes a protective plate 1014 and brush bristles 1015; the workbench 1 is fixedly connected to two arc-shaped protective plates 1014, and the protective plates 1014 are located outside the corresponding electric peeling roller 102. The protective plates 1014 are slidably connected to the corresponding support ring 103; each protective plate 1014 has several brush bristles 1015 connected to its inner lower part.

[0028] The protective plate 1014 and the bristles 1015 are connected by a snap-fit ​​structure. Considering that the bristles 1015 will wear out significantly during long-term use, thereby reducing the cleaning effect on the electric peeling roller 102, the protective plate 1014 and the bristles 1015 are connected by a snap-fit ​​structure to facilitate manual disassembly and replacement of the bristles 1015 periodically.

[0029] In this embodiment, the external liquid pump is connected to the delivery pipe 108 during use. Initially, the control cylinder 104 drives the corresponding support ring 103 to move towards the middle of the electric peeling roller 102 until the support ring 103 covers both ends of the corresponding electric peeling roller 102. Then, the wood body 2 to be peeled is placed on top of the two electric peeling rollers 102 manually or by external equipment. At this time, since the support ring 103 covers both ends of the corresponding electric peeling roller 102, the wood body 2 and the support ring 103 are connected. 3. The bark does not contact the electric peeling roller 102. Then, the electric push rod 1013 is controlled to move the connecting frame 105 and the electric cutter 106 downwards until the electric cutter 106 contacts the bark of the wood body 2. Next, the electric cutter 106 is controlled to rotate to make a slit in the bark, and the linear electric guide rail 1011 is controlled to move the moving block 1012 to move the electric push rod 1013 horizontally, so that the electric cutter 106 makes a horizontal slit in the bark of the wood body 2. After making one slit... Then, the electric peeling roller 102 is controlled to drive the support ring 103 to rotate, which in turn causes the support ring 103 to drive the wood body 2 to rotate. This allows the electric cutter 106 to cut the bark in other areas of the wood body 2. At the same time, during the peeling process, the spraying component sprays surfactant liquid onto the bark on the surface of the wood body 2 to wet and soften the bark. By pre-cutting multiple slits in the bark on the surface of the wood body 2, the waterproof barrier of the bark is destroyed, accelerating the penetration of water and softening of the bark. This significantly reduces the bonding force between the bark and the wood after it absorbs water and softens, making the subsequent mechanical peeling by the electric peeling roller 102 extremely easy. At the same time, it provides physical break points on the surface of the bark, allowing the bark to easily break and peel off along these pre-set gaps. This effectively avoids problems such as incomplete peeling or machine jamming caused by excessive bark toughness, greatly improving the overall peeling cleanliness and efficiency. Furthermore, the softened bark significantly reduces the mechanical cutting resistance, protecting the wood at the bottom layer of the wood body 2.

[0030] After the electric cutter 106 cuts the bark, the control cylinder 104 drives the corresponding support ring 103 to move away from the center of the electric peeling roller 102 until the support ring 103 disengages from both ends of the electric peeling roller 102 and the wood body 2. At this time, the wood body 2 falls down onto the two electric peeling rollers 102 under the action of gravity. Then, the two electric peeling rollers 102 are controlled to rotate to remove the bark from the surface of the wood body 2. The bark debris generated during the peeling process falls down from the rectangular groove 11.

[0031] Considering that the gap after the electric cutter 106 cuts the bark on the surface of the wood body 2 is small, making it difficult for the surfactant liquid to penetrate into the bark, when the electric cutter 106 moves along the surface of the wood body 2 to cut the bark, the connecting frame 105 drives the retaining ring 107 to move, so that the outer arc of the retaining ring 107 is engaged in the cut of the bark, thereby opening the cut of the bark during the movement. Then, the external liquid pump is started to deliver the surfactant liquid (wetting agent) into the delivery pipe 108, so that the surfactant liquid penetrates into the cut of the bark, improving the wetting efficiency of the surfactant liquid on the bark. At the same time, the surfactant liquid in the delivery pipe 108 comes into contact with the electric cutter 106 when sprayed, thereby cooling the electric cutter 106.

[0032] Furthermore, considering that the electric peeling roller 102 generates a large amount of debris when peeling the wood body 2, and that the debris is prone to splashing under the rotation of the electric peeling roller 102, and that debris will remain on the surface of the electric peeling roller 102, thus affecting the peeling of the next wood body 2, in order to solve this problem, a protective plate 1014 is used to protect the debris splashed on the outside of the electric peeling roller 102, so that the debris falls downward into the rectangular groove 11 for collection. When the electric peeling roller 102 rotates, it generates relative motion with the bristles 1015, and the bristles 1015 remove the debris remaining on the surface of the electric peeling roller 102, thereby cleaning the surface of the electric peeling roller 102 in real time.

[0033] Example 2, based on Example 1, such as Figures 4-5 As shown, the spray assembly includes a semi-circular ring 201, a connecting pipe 203, and a nozzle 204; the hollow semi-circular ring 201 is fixedly connected to the connecting frame 105; a cavity 21 is opened inside the semi-circular ring 201; the semi-circular ring 201 is connected to the connecting pipe 203; a plurality of nozzles 204 are connected to the semi-circular ring 201, and the nozzles 204 are connected to the cavity 21.

[0034] It also includes a scraper ring 207; a semi-circular ring 201 is fixedly connected to the scraper ring 207.

[0035] A sealing gasket is provided between the semi-circular ring 201 and the partition 202 to enhance the sealing performance between the semi-circular ring 201 and the partition 202.

[0036] In this embodiment, an external delivery pump is connected to the connecting pipe 203. When the linear electric guide rail 1011 causes the moving block 1012 to drive the electric push rod 1013 and its connected components to move horizontally to cut the bark of the wood body 2, the semicircular ring 201 is aligned with the center of the wood body 2. The external delivery pump is controlled to deliver surfactant into the semicircular ring 201 through the connecting pipe 203. Subsequently, the surfactant is sprayed from the nozzle 204 onto the surface of the wood body 2, thereby pre-wetting the wood surface, destroying the natural wax layer on the bark surface, softening the bark tissue, and significantly reducing the bonding force between the bark and the wood, making the subsequent physical peeling easier and more thorough, while reducing damage to the wood body 2.

[0037] Considering that there may be impurities such as peeling bark or protruding clumps of resin on the surface of the wood body 2, which may affect the cutting of the bark on the surface of the wood body 2 by the electric cutter 106, in order to solve this problem, when the semi-circular ring 201 moves horizontally, it drives the scraper ring 207 to move, so that the scraper ring 207 moves along the surface of the wood body 2, thereby scraping off the impurities such as peeling bark or protruding clumps of resin on the surface of the wood body 2 in advance.

[0038] Example 3, based on Example 2, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it also includes an arc-shaped guide rail 109, an electric slider 1010, a partition 202, a hollow tube 205, a nozzle 206, a collection box 301, and an electric rotating plate 302; the worktable 1 is bolted to two arc-shaped guide rails 109; each arc-shaped guide rail 109 is slidably connected to an electric slider 1010, and the two electric sliders 1010 are together fixedly connected to a linear electric guide rail 1011; a semi-circular ring 201 is fixedly connected to a partition 202, and the partition 202 divides the semi-circular ring into two parts. The inner part of the circular ring 201 is divided into a hollow cavity 21 and an annular cavity 22; a hollow tube 205 is fixedly connected to the semi-circular ring 201, and the hollow tube 205 is connected to the annular cavity 22; a number of nozzles 206 are connected to the annular cavity 22; a collection box 301 is slidably connected to the worktable 1, and the collection box 301 can be inserted into the rectangular groove 11; two mounting plates 101 are rotatably connected to two electric rotating plates 302, and the electric rotating plates 302 are located below the corresponding electric peeling rollers 102.

[0039] The inner side of the electric rotating plate 302 is roughened to increase the friction between the electric rotating plate 302 and the wood body 2, thereby improving the fixing effect of the electric rotating plate 302 on the wood body 2.

[0040] Specifically, in this embodiment: considering that the wood body 2 is temporarily stored after debarking and not immediately chopped for pulping, the wood body 2 loses the natural "moisturizing outer layer" of the bark. The moisture inside the wood body 2 will evaporate rapidly to the outside. The cross-sections (vessels) at both ends of the wood body 2 are high-speed channels for moisture loss, with an evaporation rate more than ten times that of the sides. This huge difference in the rate of water loss between the inside and outside, and between the ends and the middle, will generate enormous tensile force, easily causing cracks at the ends of the wood, thus affecting the quality of the wood body 2. To solve this problem, after debarking the wood body 2, artificial... First, pull out the collection box 301, causing it to detach from the rectangular groove 11. Then, control the electric rotating plates 302 to rotate in opposite directions, making them form a V-shape. Next, control the electric connecting block 1016 to move one of the electric peeling rollers 102, causing the two electric peeling rollers 102 to move away from each other. This allows the peeled wood body 2 to fall downwards between the two electric rotating plates 302. Then, control the arc-shaped guide rail 109 to cause the electric slider 1010 to drive the linear electric guide rail 1011 and its connected components to rotate below the rectangular groove 11. Figure 7 As shown, next, the electric push rod 1013 is controlled to drive the connecting frame 105 and its connecting parts to move upward until the semicircular ring 201 is aligned with the center of the wood body 2. Then, the external pump is controlled to deliver end-sealing agent liquid into the annular cavity 22 through the hollow tube 205, so that the liquid is sprayed from the nozzle 206 to the end of the wood body 2. The linear electric guide rail 1011 is controlled to drive the moving block 1012 to drive the electric push rod 1013 and its connecting parts to move horizontally, so that the nozzle 206 sprays end-sealing agent liquid onto the other end of the wood body 2. Thus, after peeling, the two ends of the wood body 2 are wrapped with end-sealing agent, which slows down the rate of moisture loss and allows the wood to dry evenly and slowly.

[0041] The collection box 301 is aligned with the rectangular groove 11 during normal debarking of the wood body 2, thereby collecting the bark debris falling from the rectangular groove 11. The electric rotating plate 302 limits and guides the bark debris, causing it to fall into the rectangular groove 11, thus improving collection efficiency.

[0042] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
