Description

The present invention has in mind to replace the manual cutting of various SHEET material in the clothing, leather, rubber, etc. industries, which is time-consuming and requires the cost of manual labor to be cut with the HELP of mechanical movable SCISSORS.

In the proposed movable device for cutting textile and similar materials, in addition to the flexible shafts that are common in cutting machines, the stem articulated with the knife and swinging a double cartridge through which the passage is used for swinging movements of the upper knife Two rods, coupled with crankshafts of different sizes, in order to change the amplitude of oscillations of the upper knife by switching on OR of another rod. To switch rods, the patron is equipped with a rod-type switch with side rods for rods.

In FIG. 1 is a side view of the bottom of the device; FIG. 2 is the same; VIEW from the front and FIG. 3 is a side view of the top of the device.

The proposed device consists of a platform / on casters mounted with a POSITION 3 and a BOTTOM knife 4. The top is attached to the hinge rack

(46)

KNIFE 5, the axis of which is placed in a movable bearing 5. Upper knife. 5 is also pivotally connected to the rod 7 passing through the plug of the frame 8, which has a handle 9.

Between the FORK frame 8 is located: DOUBLE swinging cartridge JO, through which the two upper rods // I / 2 And / 5 switch (Fig. 2) with two opposite grooves and lever M at the end, pass. The rods 7 / and / 2 have corresponding recesses for the switch 73 in their lower parts, and in the upper pivots they are connected to the rods / 5 and J6, which are mounted on the crankshaft, which has two different elbows / 7 and J8. At the same crankshaft wearing a bevel gear / p. This whole mechanism is reinforced on the ridge behind the rack 3. The conic gear / P is linked to the bevel gear 20, the shaft 2 / of which passes through the other two processes of the ZB stand Za. The end of the shaft 27 is connected through the cartridge 22 to the LOWER end of the flexible shaft 23, the other end of which is connected through the cartridge 24 (FIG. 3) to the shaft 25 of the upper drive unit. The latter consists of a frame 26, in the center of which a double gear 27 is seated, coupled with a bevel gear 28, which sits on shaft 25, and with a worm 29 "coupled with the shaft of motor 30. Electric cable 31 comes from the motor, the lower end of which is connected to the electric switch 32 (Fig. 1 and 2) with the switching lever 33.

By moving the lever 33 to the lower position on the letter P, the motor 30 is turned on, which through the worm to 29 and gears 27 and 28 rotates the flexible shaft 23, which also rotates the shaft 27 of the lower device (Figs. 1 and 2). Through gears 20 and 19, the movement is transmitted to the crankshaft / 7, which actuates the connecting rods 15 and 16 with the rods 11 and 12, one of which, for example, from the large knee 17 through the switch 13 is combined with the lower rod 7 acting on the upper 1NOZH 5, why the latter makes large fluctuations (large strides) for cutting on straight lines. For cutting along curved lines, the switch 13 turns on the rod 12, which acts from: the small bend 18 of the shaft with the same number of oscillations.

The lower unit moves along the table in either direction by the knob 9

to all management is concentrated in one place.

The subject matter of the invention.

1. A movable device for cutting textile and similar materials, provided with a flexible shaft for moving the knives and two interlocking knives, characterized in that it consists of a rod 7 coupled to the knife 5 and a double booster JO equipped with a switch / 5 and rods 7 / and 72 passing through it by I serving as regulators of the oscillation amplitude of the knife 5. /

2. The form of making the oscillatory amplitude regulator of knife 5, mentioned in p. 1, characterized in that the rods / 7 and 72 in its upper part are articulated with rods 75 and TB and crankshafts 77 and J8 of different size, and in the lower part - recesses corresponding to the protrusions of the switch 75, applied for the purpose of periodically dissociating the rods 11 tl 12 with the cartridge 10. to the author with |; I.
