Изобретение относитс к деревообрабатывающей промышленности, и в частности к производству фанеры.The invention relates to the woodworking industry, and in particular to the manufacture of plywood.

Известно устройство дл рубки лущеного шпона, включаюш,ее рабочий орган, опорный барабан, транспортеры .A device for cutting peeled veneer is known, including its working body, supporting drum, conveyors.

Наиболее близким- к изобретению техническим решением вл етс устройство дл рубки луш,еного шпона, включающее опорный барабан, нож, смонтированный на врашаюшихс ножедержател х, расположённых на одном валу, на торцах которого установлены диски 2.The closest to the invention is the technical solution for a device for cutting heads, veneer veneer, which includes a supporting drum, a knife mounted on the rotating blade holders located on the same shaft, on the ends of which there are discs 2.

Недостатком известных устройств вл етс низка производительность.A disadvantage of the known devices is low productivity.

С целью повышени качества рубки ленты шпона на форматные листы и производительности устройства, каждый из дисков снабжен фигурным выступом, установленным перед ножом таким образом, что угол между нлоскостью, проход шей через фигурный выступ и ось вращени ножедержател , и задней плоскостью ножа составл ет от 3 до 10°.In order to improve the quality of the cutting of the veneer tape on the format sheets and the productivity of the device, each of the disks is provided with a figured protrusion installed in front of the knife so that the angle between the plane and the axis of rotation of the knife holder and the rear plane of the knife is from 3 up to 10 °.

На фиг. 1изображено устройство,FIG. 1 shows the device

вид сбоку; на фиг. 2 - то же, вид спереди .side view; in fig. 2 - the same, front view.

Устройство состоит из опорного барабана 1, ножа 2, смонтированного на вращающихс ножедержател х 3, расположенных на одном валу 4, на торцах которого установлены диски 5; каждый диск снабжен фигурным выступом 6, установленным перед ножом 2 таким образом, что угол между вертикальной плоскостью устройства и задней плоскостью ножа в момент начала рубки составл ет от 3 до 10°.The device consists of a supporting drum 1, a knife 2 mounted on rotating knuckle holders 3 located on one shaft 4, on the ends of which disks 5 are mounted; Each disk is provided with a figured protrusion 6 installed in front of the knife 2 in such a way that the angle between the vertical plane of the device and the rear plane of the knife at the time of the beginning of the cutting is from 3 to 10 °.

Устройство работает следующим образом. При подаче ленты щпона 7 включаетс привод устройства, и через клиноременную передачу 8 привод тс во вращение вращающиес ножедержатели 3 и опорный барабан 1, которые наход тс в поджатом друг к другу состо нии.The device works as follows. When feeding the tape, the spike 7 turns on the drive of the device, and through the wedge-belt transmission 8, the rotating holder-holders 3 and the supporting drum 1 are driven in rotation, which are in a state pressed against each other.

Claims

The tape spike 7 is fed between the rotatable knife holders and the support drum. When reaching the zone of contact, the rotating knife holders and the tape of the spike with the figured protrusion 6 raise the knife holders above the surface of the tape of the spike 7. At the same time with the knife holders, the knife 2 is also raised so that it takes up such a position before cutting. wherein an angle of 3-10 ° is formed between the vertical plane of the device and the rear plane of the knife 2. The magnitude of this angle is determined by the diameter of the knife holders and the support drum I. The larger the diameters, the smaller the angle. Further installation of the knife holders, and with it the knife 2, leads to its abrupt transition from the upper position, which he occupied on the figure ledge 6, to the lower position (the end of the cutting of the veneer tape), i.e. At this moment, the angle is at 0. Thus, at the moment of felling, the knife 2 performs, in addition to the vrash, rolling movement, and vertical movement downwards. In this case, the cutting force developed by the knife 2 exceeds the force with a conventional kinematic scheme by 6–8 times. The proposed device makes it possible to improve the quality of cutting the veneer tape on format sheets by increasing the effort developed while simplifying the design of the device as a whole, as well as to increase the productivity of the section "cutting veneer-laying." The invention of a device for cutting veneer veneer, including a supporting drum, a knife mounted on top of one of the blade holders located on the same shaft, on the ends of which there are discs, in order to improve the performance and quality of the cutting, each of the disks a figured protrusion arranged in front of the knife in such a way that the angle between the plane passing through the figured protrusion and the axis of rotation of the knife holder and the rear plane of the knife is from 3 to 10 °.
