(54) УСТРОЙСТВО ДЛЯ РЕЗКИ РУЛОННОЙ ЦЕЛЛЮЛОЗЫ(54) DEVICE FOR CUTTING ROLL PULP

1one

Изобретение относитс к устройст- ;.вам дл резки рулонной целлюлозы и предназначено дл применени в химической , целлюлозно-бумажной и других пролгёшшенност х.5The invention relates to devices for cutting coiled pulp and is intended for use in chemical, pulp and paper, and other proliferation processes.

Известно устройство дп резки, содержащее узел поперечной резки, режущие диски, установленные в р д на приводном валу, систему дисковых ножей и узел продольной резки 1. A device for cutting dp is known, which contains a cross-cutting assembly, cutting disks mounted in a row on the drive shaft, a system of circular knives and a slitting assembly 1.

Недостатком данного устройства некачественна резка широких рулонов на мелкие пр моугольные частицы.The disadvantage of this device is the poor-quality cutting of wide rolls into small rectangular particles.

Цель изобретени - повышение кд- 15 чества резки.The purpose of the invention is to increase the cd-cut.

Указанна цель достигаетс тем, что дисковые ножи системы собраны в пакеты и смонтированы на валах, расположенных по дуге окружности концент- 20 рично относительно приводного вала, при этом пакеты установлены в шахматном пор дке..This goal is achieved by the fact that the disk knives of the system are assembled in packages and mounted on shafts located along an arc of a circle centrally relative to the drive shaft, while the packages are installed in a checkerboard pattern.

лирующих дисков; на фиг. 6 - крепле:ние ножей барабана поперечной резки.lithium disks; in fig. 6 - fastening knives of cross cut drum.

. Устройство содержит станину 1, на которой смонтированы прот жные валы 2, столики 3, привод 4, узлы продольной и поперечной резки.. The device comprises a frame 1, on which shaft shafts 2, tables 3, drive 4, longitudinal and transverse cutting units are mounted.

Узел продольной резки состоит из приводного вала 5, установленного в подшипниковых опорах 6. На валу 5 закреплены режущие диски 7 с кольцами 8, а также звездочка 9 привода вала, над валом 5 расположены валы 10 и 11, установленные в подшипниковых опорах 12. Валы 10 и 11 привод тс во вращение с помощью звездочек 13. da валах 10 и 11 установлены втулки 14, на которых смонтированы в пакет дисковые ножи 15 с прокладками 16. Втулки 14 с пакетами дисковых ножей 15 устанавливаютс на вгшах 10 и 11 в шахматном пор дке и фиксируютс на них с помощью цанговых зажимов 17. При этом режущие диски 7 и дисковые ножи 15 устанавливаютс с требуемым зазором.The slitting unit consists of a drive shaft 5 mounted in bearing supports 6. On the shaft 5 there are fixed cutting discs 7 with rings 8, as well as a sprocket 9 of the drive shaft, above the shaft 5 there are shafts 10 and 11 mounted in bearing supports 12. Shafts 10 and 11 are driven in rotation by means of sprockets 13. da shafts 10 and 11 are fitted with sleeves 14, on which circular knives 15 with spacers 16 are mounted in a package. Sleeves 14 with circular knives packages 15 are mounted on knives 10 and 11 in a checkerboard pattern and are clamped onto them with collet clamps 17. When that blades 7 and circular knives 15 are set to the required clearance.

Claims

The cross-cutting unit consists of a flat fixed knife 18, a drum 19 installed in the bearings 20. The drum 19 is rotated by a belt drive from the drive 4. On the drum 19 by means of wedge clamps 21 and bolts 22 fixed knives 23. The drum 19 saKjiHT. a housing 24 having a slit for passing the pulp strips coming from the slitting unit. The device works following the J3OM image. The pulp roll is unwound and drawn with shafts 2 along the stitches 3 is fed to the Slitting unit, where the cutting of the width of the wedge is reduced. The disk knives 15 mounted on the shaft 10 cut the pulp into strips of a given width alternating with strips of uncut pulp, which are further cut axially with the blade knives 15 mounted on the shaft 11. Next the strips of pulp are fed by another pair of rolls 2 A transverse cross cut, where they fall through the slot in the case 24 into the space between the fixed knife 18 and the rotating knives 23 of the drum 19, is cut into elements whose dimensions depend on the number of cutting knives 23. Formation on the drum 19, the number of revolutions of the drum 19 and the longitudinal feed speed. Perform longitudinal cutting assembly in the form of a system of circular knives assembled in packages on mandrels with a collet clamp and installed in staggered order on shafts located along an arc of a circle concentrically with the drive shaft with cutting disks, the mouth. This will significantly improve the quality of the slitting due to the fact that between the cutting discs 7 of the shaft 5 and the disc blades 15 of the shafts 10 and 11 easily provide the required clearances, and this also eliminates the temperature increase in the cutting zone, significantly reducing quality of the final product. Installing the drum of the cross-cutting unit with cutting knives in a casing having a longitudinal slit for the passage of pulp strips improves the quality of the transverse cutting of pulp strips due to the fact that the resolution formed by the stationary knife during the rotation of the drum promotes a smooth flow of the cut strips to the cutting knives the drum. The invention of the device for cutting coiled pulp, including a transverse assembly, comprising cutting discs mounted in a row on a drive shaft, a system of disk knots and a slitting unit, so as to improve the quality of cutting, the circular knives of the system are assembled into the bags are mounted on shafts located along the arc of a circle concentric with the drive shaft, while the packs are installed in a checkerboard pattern.
