Description

Technical Field

[0001] The present invention relates to the field of wood cutting, and particularly to a wood cutting device for furniture production. Background Art

[0002] Trunk debarking refers to removing the bark on the outer layer of the trunk through a peeling cutter wheel during the wood processing. This process can not only obtain a clean wood surface, but also cut the trunk into woods with the same diameter by the peeling cutter wheel, facilitating subsequent wood processing and utilization.

[0003] During the process of cutting and peeling the trunk epidermis, in order to ensure that the diameter of the wood is the same, the redundant solid wood part will also be cut and peeled off; however, the trunk epidermis used for furniture production has no utilization value and is usually treated as biomass fuel, while the cut solid wood part can also be used as the filling material for composite boards and the raw material for papermaking and pulp production, etc., with relatively high recycling value; therefore, it is necessary to separate and recycle the peeled trunk epidermis and solid wood part to improve the utilization rate and commercial value of the wood. Summary of the Invention

[0008] More preferably, the scraping plate is arranged in a curved arc shape.

[0009] More preferably, a serrated edge is arranged at the curved arc of the scraping plate.

[0010] More preferably, an extrusion block is further included; extrusion blocks are annularly arrayed on the outer side of each rotating ring, and the extrusion blocks are distributed on the front side and the rear side of the cutting knife.

[0011] More preferably, a sprayer and a water inlet pipe are further included; a water inlet pipe is communicated between each electric roller and the first fixing ring; a plurality of sprayers for spraying lime water on the surface of the tree trunk are arranged on the outer surface of each electric roller; a connecting pipe is arranged in each electric roller; and the connecting pipe is rotatably connected with the water inlet pipe.

[0012] More preferably, a partition ring is further included; a partition ring is fixedly connected to the middle of the cutter.

Therefore, when spraying, the scraping plate is peeling off the tree trunk, and at this time the epidermis of the tree trunk will be turned up, so the sprayed lime water can directly enter the epidermis of the tree trunk, improving the wetting and softening effect;

[0017] The solid wood part of the trunk is peeled off by a peeling knife, and the peeled solid wood sawdust is discharged through the second chip discharge groove. Then, the debris peeled off from the trunk bark and the debris peeled off from the solid wood part can be recycled separately by this method, thereby improving the utilization rate and commercial value of the wood.

[0032] The peeling assembly includes a second electric rotating ring 202 and a peeling knife 203; The right side of the cutter 3 is rotatably connected with a second electric rotating ring 202; A peeling knife 203 is fixedly connected to the inside of the second electric rotating ring 202.

[0033] The adapter assembly includes a slider 206 and a compression spring 207; A number of upper and lower symmetric sliding grooves 1001 are formed in the bracket 1; A slider 206 is slidably connected in each sliding groove 1001. A motor is fixedly connected to the rear side of the slider 206, and a conveying roller 2 is rotatably connected to the front side of the slider 206. The output end of the motor is fixedly connected to the fixed shaft of the conveying roller 2; A compression spring 207 is fixedly connected between the upper side of each slider 206 and the sliding groove 1001.

[0034] The scraping plate 106 is arranged in a curved arc shape.

[0035] The curved arc of the scraping plate 106 is provided with a serrated edge.

[0036] It also includes a pressing block 104; Pressing blocks 104 are annularly arranged on the outside of each rotating ring 10201, and the pressing blocks 104 are distributed on the front side and the rear side of the cutting knife 103.

[0037] It further includes a sprinkler 107 and a water inlet pipe 108; a water inlet pipe 108 is connected between each electric rotating roller 105 and the first fixing ring 101, and the water inlet pipe 108 is connected to an external water pump through the first fixing ring 101; a plurality of sprinklers 107 are arranged on the outer surface of each electric rotating roller 105, and the sprinklers 107 are distributed between two adjacent scraping plates 106; a connecting pipe 10501 is arranged in each electric rotating roller 105, the connecting pipe 10501 is communicated with each sprinkler 107 on the outer surface of the corresponding electric rotating roller 105, and the connecting pipe 10501 is communicated with the corresponding water inlet pipe 108; and the connecting pipe 10501 is rotatably connected to the water inlet pipe 108.

[0038] It further includes a partition ring 201; a partition ring 201 is fixedly connected to the middle of the cutter 3, and the first chip removal groove 3001 and the second chip removal groove 3002 are separated by the partition ring 201.

[0039] The middle part of the partition ring 201 is made of rubber material, and the diameter of the through hole in the middle of the partition ring 201 is smaller than the diameter of the tree trunk 555 after being processed by the scraping plate 106.

[0040] In the initial state, the compression spring 207 is in an extended state. At this time, the upper and lower sliders 206 are squeezed by the compression spring 207 towards the middle, thereby driving the upper and lower conveying rollers 2 to move towards the opposite sides; when the surface of the tree trunk 555 needs to be peeled, it is necessary to know that the tree trunk 555 moves from the left side to the right side of the cutter 3 for feeding; first, the worker first places the tree trunk 555 between the upper and lower conveying rollers 2. During this process, when the diameter of the tree trunk 555 is relatively large, at this time, the tree trunk 555 will squeeze the upper and lower conveying rollers 2 towards the opposite sides, and at this time, the compression spring 207 is compressed and contracted, thereby driving the upper and lower sliders 206 to move towards the opposite sides; thereby clamping tree trunks 555 of different diameters; and after the compression spring 207 is compressed, it will continuously generate an extended restoring force moving towards the middle, thereby driving the upper and lower sliders 206 and the conveying rollers 2 to squeeze towards the middle, thereby stably clamping the tree trunk 555; then the conveying rollers 2 are driven to rotate by the motor, thereby driving the tree trunk 555 to enter the cutter 3 from left to right;

[0041] When the tree trunk 555 enters the first fixing ring 101; at this time, the DD motor 102 will drive the rotating ring 10201 to rotate, thereby driving the cutter 103 to rotate; thereby pre-cutting the epidermis of the tree trunk 555 through the cutter 103 to obtain a cutting groove with a uniform depth, which is convenient for subsequent peeling work; at the same time, the electric rotating roller 105 will also rotate synchronously and drive the scraping plate 106 to rotate, thereby peeling the loose epidermis of the tree trunk 555 through the scraping plate 106; during this process, such as Figures 4-6As shown: After cutting by the cutting knife 103, eight cutting grooves will be formed on the surface of the tree trunk 555, and then the surface of the tree trunk 555 will be divided into eight parts, which is convenient for the scraping plate 106 to peel the epidermis of the corresponding position of the tree trunk 555; and the curved arc of the scraping plate 106 is set as a serrated edge, which is convenient for the scraping plate 106 to insert into the tree trunk 555. At the same time, as Figure 6 shown: Based on the view from the front to the back, at this time, the electric roller 105 rotates counterclockwise, which drives the scraping plate 106 to rotate counterclockwise. Then, after the scraping plate 106 is inserted into the tree trunk 555, with the rotation of the electric roller 105, the curved arc-shaped scraping plate 106 peels the epidermis of the tree trunk 555 upward; then the peeled epidermis of the tree trunk 555 will fall into the first chip removal groove 3001 and finally be discharged from the cutter 3; at the same time, when peeling the surface of the tree trunk 555, lime water is injected into the water inlet pipe 108 through an external water pump and finally sprayed out through the sprayer 107, so as to spray and moisten the surface of the tree trunk 555, and the latex on the surface of the tree trunk 555 is removed by the alkaline lime water, and at the same time, the epidermis of the tree trunk 555 is softened. The sprayer 107 is arranged between two adjacent scraping plates 106. Therefore, when spraying, the scraping plate 106 is peeling the tree trunk 555, and at this time, the epidermis of the tree trunk 555 will be turned up. Therefore, the sprayed lime water can directly enter the epidermis of the tree trunk 555, improving the wetting and softening effect and the peeling effect of the epidermis of the tree trunk 555; then the pretreated tree trunk 555 will enter the second electric rotating ring 202 through the partition ring 201. At this time, the epidermis of the tree trunk 555 has been basically peeled off, and then only the peeling knife 203 is needed to perform precise and efficient peeling and cutting work on the solid wood part of the surface of the tree trunk 555. At the same time, the partition ring 201 prevents the lime water in the first chip removal groove 3001 from entering the second chip removal groove 3002; at the same time, the middle part of the partition ring 201 is made of rubber, and the diameter of the through hole in the middle of the partition ring 201 is smaller than the diameter of the tree trunk 555 after being processed by the scraping plate 106. Therefore, when the tree trunk 555 passes through the partition ring 201, it will contact the rubber in the middle, and then the residual lime water on the surface of the tree trunk 555 will be wiped off by the rubber in the middle. Therefore, the solid wood sawdust peeled off in the second chip removal groove 3002 will not be wetted, protecting the commercial value of the solid wood sawdust.

[0042] However, after the surface of the tree trunk 555 is pretreated by the scraping plate 106, the epidermis of the tree trunk 555 has been basically peeled off. At this time, the surface of the tree trunk 555 is relatively smooth. When the peeling knife 203 rotates at a high speed, it is easy to slip when encountering the relatively smooth surface of the tree trunk 555 and is difficult to insert into the solid wood to peel and cut the solid wood. Therefore, when the cutting knife 103 performs pretreatment cutting, eight cutting grooves have been formed on the surface of the tree trunk 555 through pretreatment, and the depth of the cutting grooves is the depth of the final diameter of the wood; it is convenient for the peeling knife 203 to insert into the solid wood through the cutting grooves to perform peeling and cutting work; and when the peeling knife 203 rotates for peeling, a large rotational force will be generated, which will cause a large torsional force on the tree trunk 555. Therefore, while the cutting knife 103 is cutting, the extrusion block 104 will extrude and clamp the surface of the tree trunk 555 to prevent the tree trunk 555 from rotating and shifting; then the solid wood chips peeled and cut by the peeling knife 203 will be discharged through the second chip discharge groove 3002, and the first chip discharge groove 3001 and the second chip discharge groove 3002 are separated by the separation ring 201 to prevent the epidermal chips in the first chip discharge groove 3001 from being mixed with the solid wood chips in the second chip discharge groove 3002; thus, the chips peeled from the epidermis of the tree trunk 555 and the chips peeled from the solid wood part are separately recycled through this method, improving the utilization rate and commercial value of the wood; and eight cutting grooves are pre-cut before peeling and cutting the solid wood part to facilitate the peeling and cutting work of the peeling knife 203, greatly improving the peeling and cutting effect of the equipment; then the processed wood is sent out through the conveying roller 2 on the right side.

[0043] Embodiment 2

[0044] On the basis of Embodiment 1, as Figure 8 and Figure 9 shown, it further includes a second fixing ring 204 and a cleaning roller 205; a second fixing ring 204 is fixedly connected to the right discharge port of the cutter 3; six cleaning rollers 205 are rotatably connected to the inner side of the second fixing ring 204.

[0045] After the epidermis of the tree trunk 555 is peeled and cut, when the wood is sent out from the right side of the cutter 3, at this time, the cleaning roller 205 is used to polish and remove the wood chips and burrs on the surface parameters of the wood, and at the same time polish the surface of the wood to improve the appearance quality of the wood and make it more beautiful, and the wood can be directly subjected to cutting and forming treatment in the subsequent process.
