Description

Изобретение относится к деревообрабатывающему оборудованию и может' быть использовано в деревообрабатывающей промышленности.The invention relates to woodworking equipment and can be used in the woodworking industry.

Известен ленточнопильный станок для распиловки лесоматериалов, содержащий станину, ведущий и ведомый шкивы с ленточной пилой, направляющие и привод £13.Known band saw machine for sawing timber, containing the frame, the leading and driven pulleys with a band saw, guides and drive £ 13.

Известен также ленточнопильный станок для распиловки лесоматериалов, включающий станину,· два режущих венца для распиловки лесомате'риалов при прямой и обратной подаче, один из которых расположен на бесконечной ленте, ведущий и ведомый шкивы [2].Also known is a band saw for sawing timber, including a bed, · two cutting crowns for sawing timber materials with direct and reverse feed, one of which is located on an endless belt, leading and driven pulleys [2].

Недостатком известных ленточнопильных станков является их низкая производительность. .A disadvantage of the known band saws is their low productivity. .

Цель изобретения - повышение производительности.The purpose of the invention is to increase productivity.

Это достигается тем,что станок снабжен дополнительной бесконечной лентой с ведущим и ведомым шкивами ,и двухсторонним расклинивающим ножом, который размещен между лента2 ми, причем другой режущий венец расположен на дополнительной бесконечной ленте.This is achieved by the fact that the machine is equipped with an additional endless belt with driving and driven pulleys, and a two-sided proppant knife, which is placed between the belts 2, and the other cutting crown is located on the additional endless belt.

На фиг. 1 изображен предлагаемый станок, общий вид; на фиг. 2 показано расположение расклинивающего ножа и режущих венцов в пропиле; на фиг. 3 - крепление расклинивающего 10 ножа.In FIG. 1 shows the proposed machine, a General view; in FIG. 2 shows the location of the propping knife and cutting crowns in the cut; in FIG. 3 - fastening of the proppant 10 knife.

Ленточнопильный станок для распиловки лесоматериалов включает станину 1, бесконечную ленту 2 с режущим венцом 3, ведущий 4 и ведомый 15 5 шкивы. Станок снабжен также дополнительной бесконечной лентой б с зубчатым венцом 7, ведущим 8 и ведомым 9 шкивами. Между лентами 2 и 6 размещен двухсторонний раскли20 нивающий нож 10.Band saw for sawing timber includes a frame 1, an endless belt 2 with a cutting crown 3, a leading 4 and a driven 15 5 pulleys. The machine is also equipped with an additional endless belt b with a ring gear 7, a leading 8 and a driven 9 pulleys. Between the tapes 2 and 6 there is a double-sided propping knife 10.

Станок работает следующим образом. Производят подачу бревна 11 на режущий венец 3, который производит.· формирование пропила.The machine operates as follows. Supply log 11 to the cutting crown 3, which produces. · The formation of cut.

После заглубления бревна 11 на свю ширину ленты 2 отпиливаемые части бревна начинают контактировать с двухсторонним расклинивающим ножом 10, который раздвигает их. При этом 30 нерабочий в данный момент режущий венец 7 свободно размещается в пропиле. После окончания реза производят распиловку бревна в обратном направлении режущим венцом 7.After deepening the log 11 to its own width of the tape 2, the sawn parts of the log begin to come into contact with the double-sided proppant knife 10, which moves them apart. At the same time, 30 a non-working cutting crown 7 is freely located in the cut. After the end of the cut, the log is sawn in the opposite direction with a cutting crown 7.

В дальнейшем процесс повторяют.In the future, the process is repeated.

Использование предложенного ленточнопильного станка для распиловки лесоматериалов позволяет устранить тренце неработающего' режущего венца о стенки пропила, исключить затупление и износ его. Это, в свою очередь, обеспечивает высокое качество поверхности выпиливаемых пиломатериалов и повышение производительности станка.The use of the proposed band saw for sawing timber eliminates the trench of the idle 'cutting crown on the cut walls, and eliminates its dullness and wear. This, in turn, ensures high surface quality of sawn lumber and increased productivity of the machine.

Claims

(54) BELT SAWING MACHINE FOR CUTTING OF FOREST MATERIALS The invention relates to woodworking equipment and can be used in the woodworking industry. Known band sawing machine for sawing timber, containing the frame, the master and the driven pulleys with a band saw, and the driving and drive 1}. Also known is a timber sawing machine for sawing timber, including a bed, two cutting rims for sawing forest mat rials with direct and reverse feeding, one of which is located on an endless belt, leading and driving pulleys 2. A disadvantage of the known band saw machines is their low productivity. . The purpose of the invention is to increase productivity. This is achieved by the fact that the machine is provided with an additional endless belt with leading and driven pulleys, and a double-sided riving knife, which is placed between the belts, with the other cutting veneer. located on an additional endless ribbon. FIG. 1 shows the proposed machine, a general view; in fig. 2 shows the location of the riving knife and cutting rims in the saw; in fig. 3 - fastening riving knife. The band saw machine for sawing wood includes a bed 1 / endless belt 2 with a cutting rim 3, a lead 4 and a driven 5 pulleys. The machine is also equipped with an additional endless belt 6 with a ring gear 7, leading 8 and driven 9 pulleys. Between the belts 2 and 6 placed double-sided riving knife 10. The machine works as follows. Produces the supply of log 11 to the cutting rim 3, which produces the formation of the cut. After deepening “wood 11 to the width of the tape 2, the pulverized parts of the log begin to come into contact with the double-sided skining knife 10, which pushes them apart. At the same time, the cutting rim 7, which is currently not working, is freely placed in the pro- saw. After the cut is completed, the log is sawn in the opposite direction with a cutting rim 7. The process is then repeated. The use of the proposed band saw machine for sawing timber makes it possible to eliminate TpeHije of the non-working cutting rim against the walls of the cut, to exclude blunting and wear. This, in turn, provides high quality of sawn timber and increase machine productivity. Claiming machine for sawing timber, including a hundred: Nina, two cutting crowns for sawing timber for direct and reverse feeding, one of which is located on an endless belt, leading and driven pulleys, i-j that, in order to increase productivity, the machine is equipped with an additional endless belt with a leading and driven pulleys and a double-sided wedging knife, which is placed between the belts, with the other cutting rim located on the additional endless belt.
