Description

лировани положени втулки 17 в выступе 14.positioning the sleeve 17 in the protrusion 14.

Державка 13 ролика 12 выполнена в виде неполного кольна и жестко с ннм св занной кольцевой накладной пластины 19 с выступом 20, на котором установлен ролик 12 с возможностью вращени .The holder 13 of the roller 12 is made in the form of an incomplete wheel and rigidly connected to it an associated annular cover plate 19 with a protrusion 20 on which the roller 12 is rotatably mounted.

Регулируемый эксцентрик 2 имеет обоймуAdjustable eccentric 2 has a clip

21с отверстием, котора при помощи пальца21 with a hole that with a finger

22и т ги 23 соединена с пальцем 24 кнопки 25. При вращении кнопки 25 посредством пальца 24, рычага 23 п пальца 22 перемещаетс эксцентрик 2 на валу 1, измен етс его эксцентриситет, а вследствие этого и размеры подачи транспортирующего ролика механизма 12.22 and 23 are connected to the pin 24 of the button 25. When the button 25 rotates via the pin 24, the lever 23 and the pin 22, the eccentric 2 moves on the shaft 1, its eccentricity changes, and consequently the feed sizes of the transport roller of the mechanism 12.

При работе мащины материал 26 подаетс в то врем , когда игла 27 находитс вне материала. Прерывистое перемещение ролика 12 синхронизировано с перемещением иглы 27 посредством эксцентрика 2, установленного на главном валу 1.When the machine is working, material 26 is fed while the needle 27 is out of the material. Intermittent movement of the roller 12 is synchronized with the movement of the needle 27 through the eccentric 2 mounted on the main shaft 1.

От вала 8 при помощи шестерни 9 движение передаетс на ролик 12, который с помощью зубьев 11 перемещает материал. Наличие эксцентричной втулки 17 позвол ет установить требуемую высоту выступани зубьев ролика 12 над игольной пластиной, а также регулировку зацеплени шестерни 9 с роликом 12 и регулировку положени ролика 12, и определ ет положение ролика 12 в пазу игольной пластины.From the shaft 8, with the help of gear 9, the movement is transmitted to the roller 12, which moves the material with the help of teeth 11. The presence of an eccentric sleeve 17 allows you to set the required protrusion height of the teeth of the roller 12 above the needle plate, as well as adjusting the engagement of the gear 9 with the roller 12 and adjusting the position of the roller 12, and determine the position of the roller 12 in the slot of the needle plate.

Claims

1. A device for transporting material to a sewing machine, comprising a transport roller, provided with a ring gear for engagement with the drive bristles, and a device for mounting the roller in the groove of the sewing masking platform, having a roller holder and a fixed plate on it, connected to an eccentric, located in the housing of the sewing machine, and means for turning the eccentric, characterized in that, in order to increase the reliability of operation and

life, the eccentric is rigidly connected to the cover plate and has an eccentric sleeve freely mounted on the axis with the possibility of adjusting its position, and means for fixing the sleeve on the axis.

2. An apparatus according to claim 1, characterized in that the means for fixing the sleeve on the shaft is made in the form of a terminal connection.

3. The device according to claim. 1, characterized by

in that the means for rotating the eccentric is made in the form of a screw housed in the body of the sewing machine.
