Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disc chippers, in particular to a chipper flying knife length adjustment component. Background Art
[0002] In the papermaking industry, the quality requirements for finished paper products are getting higher and higher, which means that the quality requirements for raw materials are getting higher and higher. Before the logs enter the pulping process, they need to be sliced. The general processing technology of paper mills is to use a disc chipper to slice the logs into wood chips of uniform thickness and size.
[0003] In the related art, a disc chipper has a number of knives installed on a cutter disc, which are driven to rotate by an output shaft so that the knives can slice the logs. However, the logs contain impurities, and the long-term high-speed cutting of the knives will gradually wear out the knives. The knives need to be disassembled and sharpened to make the cutting edges sharp. However, after multiple sharpenings, the shaft length of the knives becomes shorter and shorter, and cannot meet the normal cutting requirements. The knives can only be replaced to meet the normal log cutting requirements, which increases the frequency and cost of replacing the knives. Frequent replacement of the knives will cause work stagnation and cannot guarantee work efficiency. Utility Model Content
[0004] The utility model aims to provide a chipper flying knife length adjustment component to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A chipper flying knife length adjustment component, comprising:
[0007] An adjustment block, wherein a plurality of first threaded holes are provided along the length of the adjustment block, and length adjustment devices are respectively provided in the plurality of first threaded holes;
[0008] The adjustment block is also provided with a plurality of through holes;
[0009] A flying knife, wherein a second threaded hole is arranged at the top of the flying knife and corresponding to the plurality of the through holes, and bolts are arranged in the through holes and the second threaded holes;
[0010] The length adjusting device and the bolt adjust the length of the flying knife.
[0011] The chipper flying knife length adjustment assembly according to this solution has at least the following technical effects:
[0012] The chipper fly cutter length adjustment component is provided with an adjustment block, and a length adjustment device is provided in a first threaded hole of the adjustment block. When the wheelbase of the fly cutter becomes shorter due to a sharpening process, a long bolt is loosened partially to separate the bottom of the adjustment block from the top of the fly cutter. One end of the length adjustment device is screwed out of the first threaded hole and pressed against the top of the fly cutter to push the fly cutter out to a certain length, so that the fly cutter is fully utilized to meet the required cutting length, thereby ensuring the cutting effect and performance stability of the chipper, effectively reducing the frequency and cost of replacing the fly cutter, extending the service life of the fly cutter, reducing work stagnation caused by frequent replacement of the fly cutter, and improving work continuity and efficiency.
[0013] As a further solution of the utility model: the height of the adjustment block is 20mm-60mm.
[0014] Since the height of the adjustment block is 20mm-60mm, adjustment blocks of different heights can be selected according to the remaining shaft length after the fly cutter is sharpened, so that the fly cutter can be fully utilized to meet the required cutting length, thereby meeting the cutting needs, effectively reducing the frequency and cost of replacing the fly cutter and extending the service life of the fly cutter.
[0015] As a further solution of the utility model: the length adjustment device is a hexagon socket set screw, and the bottom of the hexagon socket set screw abuts against the top of the flying cutter.
[0016] Since the length adjustment device is a hexagon socket set screw, the bottom of the hexagon socket set screw abuts against the top of the flying cutter, and a part of the hexagon socket set screw is screwed out of the first threaded hole, and the other part is retained in the first threaded hole, so that the hexagon socket set screw screwed out of the first threaded hole pushes the top of the flying cutter out, thereby extending the required use length of the flying cutter, reducing the scrap rate of the flying cutter, improving the use efficiency of the flying cutter, and reducing the replacement cost of the flying cutter.
[0017] As a further solution of the utility model: the length of the hexagonal set screw is set corresponding to the height of the adjustment block.
[0018] Since the length of the hexagonal set screw is set corresponding to the height of the adjustment block, adjustment blocks of different heights can be selected according to the remaining shaft length of the fly cutter after sharpening, and by unscrewing one end of the hexagonal set screw, the remaining shaft length of the fly cutter can be better adapted to ensure the cutting ability of the fly cutter, further improve the use efficiency of the fly cutter, and reduce the replacement cost of the fly cutter.
[0019] As a further solution of the utility model: the width of the top of the flying knife is set corresponding to the width of the bottom of the adjusting block.
[0020] By setting the width of the top of the flying cutter corresponding to the width of the bottom of the adjustment block, more stable support and cooperation can be achieved, ensuring the stability and accuracy of the flying cutter during the cutting process, ensuring the quality and precision of log processing, reducing the vibration and deviation of the flying cutter during processing, and improving the cutting effect.
[0021] As a further solution of the utility model: it also includes a tool measuring device.
[0022] After the flying knife is adjusted to a certain length by the length adjustment component, the adjusted length of the flying knife is measured by the tool measuring device to ensure that the flying knife length meets the cutting requirements, thereby avoiding the flying knife length being not adjusted properly, resulting in a decrease in the quality of log cutting, thereby affecting subsequent production efficiency and quality, eliminating the need for repeated adjustment of the flying knife and improving work efficiency.

The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0038] like Figure 1-6The utility model embodiment shown is a chipper flying cutter length adjustment component, comprising: an adjustment block 101, a plurality of first threaded holes 102 are arranged along the length of the adjustment block 101, and length adjustment devices are arranged in the plurality of first threaded holes 102 respectively; the adjustment block 101 is also penetrated by a plurality of through holes 103; a flying cutter 104, a second threaded hole 105 is arranged on the top of the flying cutter 104 corresponding to the plurality of through holes 103, and long bolts 106 are arranged in the through holes 103 and the second threaded holes 105; the length adjustment device and the long bolt 106 adjust the length of the flying cutter 104.
[0039] Specifically, the chipper cutter length adjustment assembly is provided with an adjustment block 101, and a length adjustment device is provided in the first threaded hole 102 of the adjustment block 101. When the wheelbase of the fly cutter 104 becomes shorter due to the sharpening process, the long bolt 106 is partially loosened to separate the bottom of the adjustment block 101 from the top of the fly cutter 104. By screwing one end of the length adjustment device out of the first threaded hole 102 and pressing against the top of the fly cutter 104, the fly cutter 104 is pushed out to a certain length, so that the fly cutter 104 is fully utilized to meet the required cutting length, ensure the cutting effect and performance stability of the chipper, effectively reduce the frequency and cost of replacing the fly cutter 104, extend the service life of the fly cutter 104, reduce work stagnation caused by frequent replacement of the fly cutter 104, and improve work continuity and efficiency.
[0040] Furthermore, the height of the adjustment block 101 is 20 mm-60 mm.
[0041] Specifically, since the height of the adjustment block 101 is 20mm-60mm, adjustment blocks 101 of different heights can be selected according to the remaining axial length of the flying cutter 104 after sharpening, so that the flying cutter 104 can be fully utilized to meet the required cutting length, thereby meeting the cutting requirements, effectively reducing the frequency and cost of replacing the flying cutter 104, and extending the service life of the flying cutter 104.
[0042] Furthermore, if Figure 1 As shown, the length adjustment device is a hexagon socket set screw 107 , and the bottom of the hexagon socket set screw 107 abuts against the top of the flying cutter 104 .
[0043] Specifically, since the length adjustment device is a hexagon socket set screw 107, the bottom of the hexagon socket set screw 107 is in contact with the top of the flying cutter 104. By screwing a part of the hexagon socket set screw 107 out of the first threaded hole 102 and retaining the other part in the first threaded hole 102, the hexagon socket set screw 107 screwed out of the first threaded hole 102 pushes the top of the flying cutter 104 out, thereby extending the required use length of the flying cutter 104, reducing the scrap rate of the flying cutter 104, improving the use efficiency of the flying cutter 104, and reducing the replacement cost of the flying cutter 104.
[0044] Furthermore, the length of the hexagonal set screw 107 is set corresponding to the height of the adjustment block 101 .
[0045] Specifically, since the length of the hexagonal set screw 107 is set to correspond to the height of the adjustment block 101, the adjustment block 101 of different heights can be selected according to the remaining axial length of the flying cutter 104 after sharpening, and by unscrewing and adjusting one end of the hexagonal set screw 107, the remaining axial length of the flying cutter 104 can be better adapted to ensure the cutting ability of the flying cutter 104, further improve the use efficiency of the flying cutter 104, and reduce the replacement cost of the flying cutter 104.
[0046] like Figure 2 As shown, the width of the top of the flying cutter 104 is set correspondingly to the width of the bottom of the adjusting block 101 .
[0047] Specifically, by setting the width of the top of the flying knife 104 corresponding to the width of the bottom of the adjustment block 101, more stable support and cooperation can be achieved, ensuring the stability and accuracy of the flying knife 104 during the cutting process, ensuring the quality and precision of log processing, reducing the vibration and deviation of the flying knife 104 during the processing process, and improving the cutting effect.
[0048] like Figure 6 As shown, the chipper flying cutter length adjustment assembly further includes a cutter measuring device 108 .
[0049] Specifically, after the flying knife 104 is adjusted in length by the length adjustment component, the adjusted length of the flying knife 104 is measured by the tool measuring device 108 to ensure that the length of the flying knife 104 meets the cutting requirements, avoid the flying knife length being not adjusted properly, resulting in a decrease in the quality of log cutting, thereby affecting subsequent production efficiency and quality, eliminating the repeated adjustment process of the flying knife 104 and improving work efficiency.
