Description

FIELD OF THE INVENTION This invention relates to dope manufacturing in the textile industry, and in particular to devices for laying a tape in a basin for carding and banding machines.

The purpose of the invention is to increase reliability.

For this purpose, in a device comprising a plate mounted with the possibility of slow rotation, a freely mounted upper plate and flatting rollers parallel to the plane of rotation of the upper plate according to the invention, it is assumed that the plate is eccentrically mounted on two gear cylindrical wheels, with the possibility of rotation separately relative to each of them. kinematically interconnected by a spurious gear. The wheels are driven from an individual engine, for example, from a motor-ed / ktor. The composite ribbon guide is designed so that its first part is mounted to rotate around the axis of the pelvis, the second - around the axis of the upper plate and rotation of the first part.

The eccentric installation of the slowly rotating plate, which functions as the lower plate, on two cylindrical gears with the possibility of rotation individually relative to each of them, provides rotation of the upper plate, with its axis of rotation located at the direct location of the plate mounting points on the gears, around the axis of the pelvis between the axis of rotation of the upper plate and the axis of the pelvis, an eccentric of XJ 00

trisite E. The kinematic coupling of the spur gears to each other by means of a spurious gear ensures their rotation in one direction. Since the bearings of the spur gears on which the plate is mounted eccentrically require bearings with an internal diameter of 50-80 mm, i.e. the most common size, which coincides with the need to install a scarce special bearing that requires careful maintenance, which increases labor productivity and reduces cost of the paver. The implementation of the drives of the upper plate and plate from individual engines simplifies their kinematics, avoids gears with intersecting axes, such as bevel gear pairs, that is, reduce noise and quick wear response. The use of a composite tape guide, the first part of which is mounted for rotation relative to the pelvis, and the second - relative to the axis of rotation of the upper plate provides a fixed installation of flattening rollers and their flexible kinematic connection, for example, by means of a chain transmission, directly with the release mechanism without intermediate links, which is beneficial it will affect the flatness of the carding tape laid in the basin

In FIG. 1 shows a belt stacker with a fixed basin; FIG. 2 is a section AA in FIG. 1.

The fixed-bed belt stacker consists of a slowly rotating plate 1, in which the upper plate 2 is freely mounted, driven by an individual motor 3, for example, a gear motor. In the case of the upper part of the rack 4, driven by an asterisk 5, a pair of flattening rollers is mounted 6. Behind the rollers 6 (Fig. 1), in the course of the product movement, a composite duct tape is installed, the first part 7 of which is rotated when interacting with the second part 8: around the axis pelvis. The second part 8 of the composite air line coupled with the upper plate 2 rotates around the axis of rotation of the upper plate. The plate 1, in turn, is eccentrically mounted on two gear cylindrical wheels 9 and 10 kinematically connected by means of a parasite gear 11. The wheels 9 and 10 are driven by an individual engine 12, for example, a gear motor, through the intermediate wheels 13. The center of the upper plate is located on the continuation of the straight line connecting the mounting points of the plate 1 to the cylindrical wheels 9 and 10.

The direction of rotation of the working bodies is indicated by arrows.

The operation of the tape stacker is as follows.

Fixed-bed conveyor

works as follows. The tape to be laid in the pelvis is fed into the interaction zone of the flattening rollers 6, which receive movement directly from the release mechanism by means of a chain transmission through an asterisk 5, which eliminates the presence of intermediate links in the transmission of movement to the flatting rollers and this eliminates the unevenness of the carding

5 of the tape resulting from the kinematic inaccuracy of the functioning of the intermediates. Exclusion of gear conical pairs significantly reduces noise during operation

0 tape stacker. The flattening rollers are mounted in the housing-upper part of the stationary stand 4 (Fig. 1), where the first part 7 of the composite tape 5 is fixed with the possibility of rotation relative to the pelvic axis, and is driven by the second component 8 when the upper plate 2 is rotated. The flatting rollers 6 serve the carding tape into a composite tape guide consisting of a first part 7 and a second part 8.

0 The second part 8 is rigidly fixed in the upper plate 2 and together with it makes a rotational movement around the axis of the upper neutron, Since the second part 8 of the composite ribbon guide is tilted relative to

5 of the axis of rotation of the top of the upper plate 2, when it is rotated in one revolution of the plate, a loop of tape is formed. Due to the fact that the upper plate 2 is mounted in a slowly rotating plate 1 with an eccentricity E with respect to the axis of the pelvis, the center of the upper plate 2, together with the plate 1, rotates in a circular motion with a radius equal to E, that is, plate 1 is made em function

5 bottom plates of the conveyor with a movable basin. When one turn of the tape is formed, the plate 1 rotates by the thickness X of the tape. To this end, the plate 1 is mounted with an eccentricity equal to E on the gears tn0 of the spur gears 9 and 10 kinematically connected to each other by a spurious gear 11 in order to have the same direction of rotation. An individual engine 12, for example, a geared motor with intermediate wheels 13, is used as a source of movement for these wheels 9, 10.

The technical advantages of the invention in relation to the prototype are.

- there is no need to install a particularly scarce special bearing with an inner diameter of 500-1000 mm, requiring careful maintenance, which allows to reduce the cost of the conveyor and increase labor productivity;

- Decrease in the noise level during the work of the conveyor due to the introduction of individual motors for the drives of the upper plate and plate, for example, gear motors, improves working conditions and increases the wear resistance of the elements of the device. The slight inconsistency in the functioning of flattening rollers, the upper plate and the plate due to the lack of kinematic connection between them is compensated by a certain deviation from the correct shape of the turns of tape laid by the upper plate, which practically does not affect the unevenness of the carding tape, its internal structure ;

-use of a composite tape guide,

in which the first part rotates relative to the axis of the pelvis, and the second part rotates relative to the axis of rotation of the upper plate, provides a fixed installation of flatteners and their flexible kinematic connection, for example, by means of a chain transmission, directly with the release mechanism of the carding machine without an intermediate exact links that give an error in the transmission of movement, which reduces the unevenness of the carding tape, improving the quality of the product;

-dividing the drive and placing them in different places of the conveyor allows access to their component parts, allows you to unload the drive of the conveyor,

as a result, it is possible to sharply increase its productivity, which is very important at the present time, when the productivity of modern carding machines reaches 100-150 kg / h.

The use of the invention allows to increase labor productivity, improve service conditions, increase the wear resistance of the conveyor units and the quality of the produced tape.
