Description

The proposed machine is designed to pre-load semi-finished products of felt boots and felts made from loose or combed wool.

In FIG. 1 is a side view of the machine; FIG. 2 is a front view.

The main working elements of the machine are the four shafts 1, 2, 3 and 4, shown in FIG. 1, 2. The shafts 1, 2 and 3 have a corrugated surface, and the shaft 4 is smooth or corrugated and of reduced diameter. Shafts 1 and 2 (Fig. 1) rotate in bearings attached to the frame, and on one side are connected to each other by a belt or chain drive using pulleys or gears. One of the lower shafts is the drive shaft of the entire machine, and therefore it is equipped with an idler and a working pulley 6 and a belt transfer 7. The upper movable shaft 3 freely rotates in bearings sliding in guide slots x 8 attached to the frame and connected by rods 9 to the pedal lifting mechanism 10. The pedal mechanism consists of a shaft rotating in special bearings of the bed two arms .

mounted on the ends of the shaft, a pedal board attached to the outer ends of the levers, and two tons of g 9 connected by hinges to the other ends of the hub and the bearings of the upper shaft.

The side shaft 4 is provided with a special frame of a rigid structure rotating at a certain angle in the bearings located in the upper part of the guide 8. The shaft frame 11 (Fig. 1 and 2) consists of two levers 12, a handle 15 and a link 13 connecting the Levers 12. Bearings are attached to the ends of the levers 12, in which the shaft 4 rotates freely. The frame has an offset center of gravity, under the action of which it rests with bearings against the stops of the guide 8. The braking sector 16 sits on the end of the axis And 3-brake pulley 17.

The machine is equipped with a horizontal or inclined working table 18, raised to the level of the upper hall, and a receiving table 19 located behind the machine and inclined from the machine.

Two shields are not shown in the drawing, which are fixed to the bed at the ends of the shafts and have a corresponding cutting

for the axis of the upper shaft. The purpose of the shields is to keep the rollers K from shifting during operation to one side or another.

Work on the machine is as follows. On the work table 18, a prefabricated felt boot or felt, wrapped in canvas in the form of a roller, is laid out of wool. The upper shaft 3 is raised with the help of the pedal 10. The roller rises by hand into the machine and, after hitting the rotating shafts 1 and 2, begins to rotate and by inertia and under the action of these shafts, it hits the side shaft 4, which does not allow it to jump out of the car on the table 19. After that, using the pedal 10, the upper shaft 3 is gently lowered onto the roller and comes into rotational motion from the roller R . When the processed roller K has a large diameter, the frame of the side shaft deviates slightly.

In this way, in a few seconds, a roller is put into the machine, which is processed in the machine for 1-3 minutes.

The extraction (ejection) of the roller from the machine is carried out as follows. The upper shaft 3 rises by pressing the foot on the pedal 10 and using the brake pulley 17 brakes the brake sector 16. After that, the left shaft 3 vigorously lowers and hits the roller K, which, having received strong braking from the side of shaft 3, is quickly carried away by the rotating shaft 2 It hits the side shaft 4 forcefully, deflects it together with the frame 8, and is thrown onto the receiving table 19. Thus, the roller is removed from the machine for approximately one second. After the roller is thrown out of the machine, the frame automatically assumes the normal position.

When the roller is thrown out of the machine, the frame with the shaft 4 can be moved to the desired angle by hand with the aid of the handle 15. This avoids striking the frame against the stops of the guide 8, lined with an elastic material.

When the roller is thrown out of the machine, braking of the upper shaft 3 using the pulley 17 and the braking sector 16 is not necessary. In this case, braking

-P. E.

the upper shaft is achieved by means of a strong deformation of the roller K due to the impact of its shaft 3.

The above described method of laying and throwing rollers from the car on the go. This is advisable and saves you the time spent on this operation.

In addition, the machine can make the laying and excavation of rollers with a stop machine.

In this case, the machine stops, the upper shaft rises, the roller collides with the table into the machine, and then the upper shaft smoothly lowers onto it. The work then proceeds normally: the machine stops to remove the roller, the upper shaft rises, and the roller R is removed by hand through the front table 18. In this case, table 19 can be removed and the frame can be replaced with permanent bearings attached to 8 guides or in a different way.

Compaction of the semifinished felt and felt is carried out several times, depending on the density that it requires. Stalling - compaction of wool in the roller, processed in the machine, is explained by the strong variable deformation of the latter when processed in the machine. The machine replaces the manual method of compacting the semi-finished products with legs or elbows, increasing the productivity by 4-5 times.

The subject of the patent.

1.Catal machine for felt production, characterized with the use of two lower working corrugated shafts 1, 2, rotating in bearings fixedly installed in the frame, one upper corrugated working shaft 3, which can move into the slots of the 8th frame by foot pedal mechanism 10-9 and a smooth roller guide 4 mounted on the end of the lever 15.

2. In the case of the tire described in paragraph 1, the use of a brake device consisting of sector 16 fixed on the rotary shaft 11 and a pulley 17 fixed on the axis of the upper roller 3, mating with the lifting of the latter.
