Description

1 . . one . .

Изобретение относитс к упаковочному оборудованик) и может быть использовано в устройствах цл резки парафинирован- . ной бумаги на форматы любого размера.The invention relates to packaging equipment) and can be used in wax cutting devices. Noah paper on any size.

Известен механизм цп поперечной резки бумаги, соцержшций поцак ций и отрывные валки, установленный в корпусе нож и привоа ;1 .The known mechanism of the central processing unit is the transverse cutting of the paper, the social formations of the withdrawals and the separation rollers, the knife and the gear mounted in the housing; 1.

Резка маги в этом устройстве осуществл етс во врем остановки подак щих и отрывных валков. При этом между подакицими и отрывными валками не сознаетс гарантированного нат жени отрезаемого полотна, что снижает качество резки..The cutting of the magi in this device takes place during the stopping of the feed and tear-off rolls. At the same time, between the pumping rollers and the separating rollers, the guaranteed tension of the cut blade is not recognized, which reduces the quality of cutting.

Целью изобретени вл етс п 51вышёние качества резки.The aim of the invention is to increase the cutting quality.

Поставленна цель достигаетс тем, что в механизме дл поперечной резки б умаги, содержащем подающие и отрывные валки, установленный в корпусе нож и привод, привод содержит кулачо св занный с ним конечный выключатель, смен-The goal is achieved by the fact that in the mechanism for cross-cutting, a cutter containing feed and tearing rolls, a knife installed in the housing and a drive, the drive contains a limit switch connected to it,

ную зубную передачу, одно из зубчатых KOJtec которой установлено на одном валу с кулачком, муфту останова подакщих валков, кинематически св занную с отрывными валками, и установленные в корпусе ножа электромагниты, электрически св занные с конечным выключателем.a new tooth transmission, one of which KOJtec gear is mounted on the same shaft with a cam, the stop roll clutch of the supporting rolls, kinematically connected with the tear rollers, and electromagnets installed in the knife body, electrically connected with the end switch.

/у1еханизм дл поперечной резки бумаги содержит подающие валки I, отрывные валки 2, установленные в корпусе S нож 4 и привод, содержащий кулачок 5, св 5 занный сним концевой выключатель 6, муфту 7 останова подающих валков 1. Привод включает черв чный редуктор 8 с алектроовигателем, звездочки 12, соединенные цепью 13. Дл обеспечени The mechanism for cross-cutting paper contains feed rolls I, tear-off rolls 2, a knife 4 mounted in housing S and an actuator containing cam 5, 5 connected limit switch 6, coupling 7 for stopping the feed rolls 1. The drive turns on a worm gear 8 with an electromotor, sprockets 12, connected by a chain 13. To ensure

Claims

20 cutting paper into formats of the required length, the drive contains an interchangeable gear transmission, one gear wheel 14 of which is mounted on the same shaft with cam 5. Electromagnets 15 are electrically connected to the final switch 6 using 3 knives 4. After the device is put into operation, the mage, unwinding from a roll, is cut into strips by knives 16 and fed under the mechanism for (topper for cutting paper into tear-off rolls

2. The cam 5, which is on the same shaft with an interchangeable oak wheel 14, during rotation acts on the limit switch 6 which gives a command to turn on the magnets 15 and turn off the clutch 7 to stop the feed rolls I. By changing the wheel 14 you can get paper sizes of the required length . The invention The mechanism for the transverse cutting of paper, comprising feeds and tear rollers, a knife mounted in a housing and a drive, characterized in that, in order to improve the quality of cutting, the drive with a rotary cam, an associated gear switch, one of the gear wheels of which is mounted on the same shaft with the cam; a stop roll clutch of the feed rolls, kinematically connected with the tear rolls, and electromagnets installed in the knife body, electrically connected with the limit switch. Sources of information taken into consideration during examination I. US Patent N 3587376, cl. 83-110, published. 1969 (prototype).
