Technical Field

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

[0002] Trunk peeling refers to the process of removing the outer bark of a tree trunk by means of a peeling wheel during wood processing. This process not only produces a clean wood surface, but also allows the peeling wheel to cut the trunk into pieces of wood of the same diameter, making it easier to process and utilize the wood in the future.

[0003] In the process of cutting and peeling the tree trunk bark, in order to ensure that the diameter of the wood is the same, the excess solid wood part will be cut off and peeled off; but the tree trunk bark 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 filling material for composite panels and raw materials for paper and pulp production, etc., and has a high recycling value; therefore, it is necessary to separate and recycle the peeled 555-trunk bark and solid wood part to improve the utilization rate and commercial value of the wood. Summary of the invention

[0034] The scraper plate 106 is configured to be in an arc shape.

[0035] The scraper plate 106 is provided with a serrated edge at the curved portion thereof.

[0036] It also includes extrusion blocks 104 ; each rotating ring 10201 has extrusion blocks 104 in a circular array on the outside, and the extrusion blocks 104 are distributed on the front and rear sides of the cutter 103 .

[0037] It also includes a sprayer 107 and a water inlet pipe 108; a water inlet pipe 108 is connected between each electric roller 105 and the first fixed ring 101, and the water inlet pipe 108 is connected to an external water pump through the first fixed ring 101; a plurality of sprayers 107 are arranged on the outer surface of each electric roller 105, and the sprayers 107 are distributed between two adjacent scraper plates 106; a connecting pipe 10501 is arranged inside each electric roller 105, and the connecting pipe 10501 is connected to each sprayer 107 on the outer surface of the corresponding electric roller 105, and the connecting pipe 10501 is connected to the corresponding water inlet pipe 108; and the connecting pipe 10501 is rotatably connected to the water inlet pipe 108.

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

[0039] The middle part of the separation ring 201 is made of rubber material, and the diameter of the through hole in the middle part of the separation ring 201 is smaller than the diameter of the tree trunk 555 after being processed by the scraper 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 toward the middle by the compression spring 207, thereby driving the upper and lower conveying rollers 2 to move toward the opposite sides. When the surface of the trunk 555 is to be peeled, the trunk 555 is fed from the left side to the right side of the cutter 3. First, the worker puts the trunk 555 between the upper and lower conveying rollers 2. During this process, when the diameter of the trunk 555 is large, the trunk 555 will push the upper and lower conveying rollers 2 toward each other. The compression spring 207 is compressed and contracted, thereby driving the upper and lower sliders 206 to move to the opposite sides; thereby clamping the tree trunks 555 of different diameters; and the compression spring 207 will continue to generate a stretching and restoring force to move toward the middle after being compressed, thereby driving the sliders 206 and the conveying roller 2 on the upper and lower sides to squeeze toward the middle, thereby stably clamping the tree trunk 555; and then the conveying roller 2 is 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 fixed ring 101, the DD motor 102 drives the rotating ring 10201 to rotate, and then drives the cutter 103 to rotate. Then, the cutter 103 performs a pre-cutting process on the skin of the tree trunk 555 to obtain a cutting groove of uniform depth, which is convenient for the subsequent peeling work. At the same time, the electric roller 105 also rotates synchronously and drives the scraper 106 to rotate, and then the loose skin of the tree trunk 555 is peeled off by the scraper 106. In this process, Figure 4-Figure 6As shown in the figure: after cutting by the cutter 103, eight cutting grooves will be formed on the surface of the trunk 555, thereby dividing the surface of the trunk 555 into eight parts, so that the scraper 106 can peel off the skin of the trunk 555 at the corresponding position; and the curved part of the scraper 106 is set as a serrated edge, so that the scraper 106 can be inserted into the trunk 555. Figure 6 As shown in the figure, the electric roller 105 rotates counterclockwise, thereby driving the scraper 106 to rotate counterclockwise. After the scraper 106 is inserted into the tree trunk 555, the curved scraper 106 peels off the bark of the tree trunk 555 upwards as the electric roller 105 rotates. The peeled bark of the tree trunk 555 falls into the first chip removal groove 3001 and is finally discharged from the cutter 3. At the same time, when the surface of the tree trunk 555 is peeled off, the external water The pump injects lime water into the water inlet pipe 108, and finally sprays it out through the sprinkler 107, thereby spraying and moistening the surface of the trunk 555, and removing the latex on the surface of the trunk 555 through the alkaline lime water, while softening the skin of the trunk 555. The sprinkler 107 is set between two adjacent scraping plates 106, so when spraying, the scraping plates 106 are peeling the trunk 555, and the skin of the trunk 555 will be turned up, so the sprayed lime water can directly The pre-treated tree trunk 555 enters the second electric rotating ring 202 through the separation ring 201. At this time, the skin of the tree trunk 555 has been basically peeled off. Then, the peeling knife 203 only needs to perform accurate and efficient peeling and cutting work on the solid wood part of the surface of the tree trunk 555. At the same time, the separation ring 201 prevents the lime water in the first chip removal groove 3001 from entering the second chip removal groove 3001. In the chip groove 3002; at the same time, the middle part of the separation ring 201 is set to rubber material, and the diameter of the through hole in the middle of the separation ring 201 is smaller than the diameter of the trunk 555 after being processed by the scraper plate 106. Therefore, when the trunk 555 passes through the separation ring 201, it will come into contact with the rubber in the middle, and then the lime water remaining on the surface of the trunk 555 will be wiped off by the rubber in the middle. Therefore, the solid wood sawdust peeled off in the second chip groove 3002 will not be wet, thereby protecting the commercial value of the solid wood sawdust.

[0042] However, after the surface of the trunk 555 is pretreated by the scraper plate 106, the epidermis of the trunk 555 has been basically peeled off. At this time, the surface of the trunk 555 is relatively smooth. The peeling knife 203 is easy to slip when encountering the relatively smooth surface of the trunk 555 during the high-speed rotation, and it is difficult to insert into the solid wood to peel and cut the solid wood. Therefore, when the cutter 103 performs pretreatment and cutting, the surface of the trunk 555 has been pretreated to form eight cutting grooves, 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 to peel, it will generate a large rotational force, which will cause the trunk 555 to generate a large torsional force. Therefore, when the cutter 103 is cutting, the extrusion block 104 will squeeze the trunk 555. 55 is squeezed and clamped on the surface, thereby preventing the trunk 555 from rotating and deviating; then the solid wood chips peeled and cut by the peeling knife 203 will be discharged through the second chip groove 3002, and the first chip groove 3001 and the second chip groove 3002 are separated by the dividing ring 201, to prevent the epidermal chips in the first chip groove 3001 and the solid wood chips in the second chip groove 3002 from mixing with each other; then, the chips peeled from the epidermis of the trunk 555 and the chips peeled from the solid wood part are recycled separately by this method, thereby improving the utilization rate and commercial value of the wood; and before the stripping and cutting of the solid wood part, eight cutting grooves are pre-cut to facilitate the stripping and cutting work of the peeling knife 203, thereby greatly improving the stripping and cutting effect of the equipment; and then the processed wood is sent out through the conveying roller 2 on the right.

[0043] Example 2

[0044] On the basis of Example 1, Figure 8 and Fig. 9 As shown, it also includes a second fixing ring 204 and a cleaning roller 205; the 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 bark stripping and cutting of the trunk 555 is completed, when the wood is sent out from the right side of the cutter 3, the wood chips and burrs on the surface parameters of the wood are polished and removed by the cleaning roller 205, and the surface of the wood is polished to improve the appearance quality of the wood and make it more beautiful. In the subsequent process, the wood can be directly cut and shaped.
