Abstract

The device is intended for the manufacture of carton containing the boxes and inserts themselves. The device consists of a bed 1, on which a stationary cutting mechanism 2 and a cross cutting mechanism are installed, which contain drive shafts 4 with clutches 8, rotating feed rollers 11 and disk knives 9 mounted on supporting shafts 5 of the joint. Hard-mounted rollers or knives can be lifted above the cardboard when the carrier shafts 5 are rotated from the pneumatic cylinders 18. The cross-cutting mechanism in the form of two sections allows ready-made blanks of boxes and liners to be automatically guided to different stored materials. Some of the rollers and clutches have attached elastic plates that, in the process of cutting, the workpieces are pressed to the basic guides. There are 6 bearing housings, an electric motor 7 and disk knives 10 rigidly mounted on the shafts 5. 5 Il. (L cond vj IC SrigL CD

Description

The invention relates to the pulp and paper industry, in particular to the manufacture of blanks for cardboard boxes.

The aim of the invention is the expansion of technological capabilities by obtaining various options for cutting blanks.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view of B in FIG. one; in fig. 5 is a section of YYD in FIG. 2

The device for making cardboard blanks consists of a frame 1 on which mechanisms of longitudinal cutting 2 and transverse cutting 3 are installed.

The mechanism 2 longitudinal cutting includes a drive shaft 4 and a carrier shaft 5 installed in the bearing housings 6. The drive shaft 4 is connected to the electric motor 7 and the clutches 8, transmitting

to the clutches 30, which are made with elastic-based plates 39, pressing the webs 21 and 22 to the longitudinal guide 40. The power cylinder 41 of each section rotates the supporting shaft 27 by a certain angle on command from the control panel. The feed rollers 33 guide the finished blanks to the storage means 42.

The device works as follows.

On command from the control panel, the shaft of the electric motor 7 and the drive shaft 4 connected to it with the clutches 8 are rotated by means of which the disk knives 9 and 10 and the feed rollers 11 and 12 are rotated. At the same time, the shafts of the electric motors are rotated. 29, drive shafts 26 with clutches 30, circular knives 31 and feed rollers 33. The power cylinders 41 sections 24 and 25 automatically rotate the bearing shafts 27

nym compound. The springs 16 provide clamping rollers 17 circular knives 9 and feed rollers 11 and 12 to the clutches 8. The power cylinder 18 rotates the carrier shaft 5 on a command from the microswitch 19 at a certain angle. The feed rollers 12 are made with elastic-based plates 20, which press the webs 21 and 22 of the cardboard to the transverse guides 23.

Mechanism 3 cross cutting 30

When the cardboard sheet reaches the microswitch 19, the latter commands the actuating cylinder 18, which rotates the carrier shaft 5 at a certain angle and lifts the disk knives 10 connected 25 to the carrier shaft 5 with a keyed joint, over the cardboard sheet. Cutting cardboard disc knives 10 stops. When the cardboard sheet is completely out of the feed rollers 12, the base plates

After finishing the circular knives 31, longitudinal on the supporting shaft 27, rigidly mounted feed rollers 32 and hinged mounted feed rollers 33. Disc knives 31 and feed rollers 32 and 33 of the installed cut from the console. The control command is given to the power cylinders 41, which rotate the bearing shafts 27 at a certain angle and lower the feed rollers 32 onto the cardboard webs 21 and 22. Placed on the supporting shaft 27 with the aid of the hoop ear 0, the cooking begins to move under the disk 34 and – t h 35, the rigidly installed feed knives 31, which cut

In the proposed device, the mechanism 2 of the carrier shaft 27, performed the necessary 55 longitudinal cutting, performs a simultaneous adjustment of the dimensions of the blanks. Spring-loaded longitudinal cutting of billet blanks 37 ensure the rollers 38 are bent and inserted. One section of the mechanical knives 31 and the feed rollers 33 ma 3 of the transverse cutting is performed by the singing rollers 32 are additionally connected to the carrier shaft 27 by a keyed joint. Fasten the earrings 34 with a screw 36, you can move all the knives and rollers along
