Description

The invention is an improvement of machines for the longitudinal cutting of a belt plate into separate drive belts.

Machines of the same designation are known, made in the form of a bed with a shaft mounted on it for the use of cut belts, drive pulling rollers, directed with a single tool and a knife holder attached to the rods of the pneumatic cylinder roll, shaft for the roll of the plate being machined and the shaft.

The machine has the following feature: to automate the attack of the plate being machined, it is equipped with cross-beams mounted on the plate side, not guiding the fingers fixed to the piston rods of the pneumatic cylinders, three-way cranes with electromagnetic drive for intildin compressed air and end switches interacting with traverses n included in

Tsey tshtanni electromagnetic drive cranes. In order to regulate the clearance for the passage of the plate, the machine is equipped with a strap fixed on the piston rods of the pyramic qi; p1ndr015 for the mixed cylinders.

FIG. 1 shows the kinematic scheme of the described machine; in fig. 2 is a diagram of its neural devices.

The described machine consists of a bed, a drive shaft, pulling 1x rollers, guide plates, an idler, a cross member for guiding the plate, a slat for adjusting the gap, a drive for pneumatic cylinders for a knife holder, a cross arm and plank.

A shaft 2 for a roll of the plate to be machined, a drive shaft 3 for receiving the cut belts, a pair of drive conveyors 4, is directed to the frame / table; it is directed to: 1 plate of the plate 5, a knife holder 6 with knives. Knife holder set15. movably in vertical, solid; 1G1p; on rods 7 pistons pneumatic nilnidron CV double acting.

 For the rotation of the transvortioHHx of the rollers 4 and the reception shaft 3, it is made in the form of an electric motor 9 connected by an E. partial coupling W with a gearbox / U. The gearbox through the gears J2 and the three-speed gearbox 13, controlled by the handwheel M, is connected to a gear with sprocket 75.

Transmission sprockets via gear 16 are connected with an asterisk / 7 of one of the transport rollers 4, equipped with a cam clutch / tV coupled.

Another notched chain J9 connects the transmission sprockets with the sprocket 20 of the friction clutch 21 mounted on the main drive shaft 3.

To align the vrashenn of both ends of the drive shaft 3, the latter is connected to the shaft 23 by means of the day gear 22.

In order to automate the side direction of the plate being machined, the machine is equipped with side plates 24 mounted on the sides of the plate, freely movable along guide rails 25, bearing pins 26 guiding the plate. Traverse is fixed on the rods 27 of the pneumatic cylinders 28 of bilateral two-way operation.

In order to power the pneumatic cylinders 28 with compressed air, the machine is equipped with three-way cranes 29 with electromagnetic actuator (the electromagnetic actuator is not shown in the diagram) and end switches 30 that interact with the traverses and are included in the power supply circuit of the electric cranes.

In order to regulate the gap for the passage of plastic, the machine is equipped with a planar 31 fixed on the rods 32 of the pistons of pneumatic cylinders 33 of double-sided action.

The pneumatic cylinders 8 and 33 of the blade-holder are controlled by three-way manual fans 34.

In order to determine the length of the treated plate, the machine is equipped with a counter 35 connected by means of a flexible shaft 36 and a worm gear 37 with one of the transport rollers 4.

The action of the fire-extinguished machine proceeds as follows.

The roll of the plate to be machined is fixed on the shaft 4 and, when the knife holder 6 is not in the working position and the base strip 3J, manually feeds its initial end to the transport rollers 4.

Installing the crosshead 25 with finger 26 across the width of the plate to be machined, raise the bar 31 to obtain a proper clearance for the passage of the plate, put the holder with the knives into position 15 and turn on the drive. When the protrusion roller is moved by the machined plate, it is cut with knives into separate drive belts, which, at the initial low speed of the drive, are fixed to one that 3 and then turn on the normal drive speed. The length of the plate-cut plate is determined by the counter 35.

Subject invention

1. A machine for longitudinal cutting of the belt plate into separate drive belts, made in the form of a bed with a shaft mounted on it for receiving the cut belts, driving givayushi nothroats, guide plates and a knife holder fixed on the piston rods of pneumatic cylinders, shaft for the roll of the processed nlastina and the drive, characterized in that, in order to automate the direction of the plate being processed, it is provided with traverses mounted on the sides of the plate, which carry the naravlya Pneumatic cylinder cylinders mounted on piston rods, three-way valves with electromagnetic actuators for supplying the cylinders with compressed air, and end switches that interact with the cross-arms and included in the power supply circuit of an electromagnetic magnet drive drive. 2. The form of the machine according to claim 1, differing from the fact that, with the adjustment of the gap for the passage of the formation, it is equipped with a bar fixed on the piston rods of pneumatic cylinders to move the bar .
