SU60384A1 - A device for detecting roving unevenness with several pairs of rollers - Google Patents

Description

Instruments for detecting uneven layers of thickness in thickness are known, including several pairs of rollers, the upper ones of which are associated with recording devices.

However, the use of such devices to determine the influence of the roughness of the rove on the process of its extraction yields incomplete data, since this process is affected by the unevenness of the level, not too thin in thickness, but also in strength, which in turn depends on twist, fiber length, technological conditions of previous processing and other factors.

In the proposed device, the tsar of its rollers is mounted in a balanced carriage, kinematically connected with a device that registers the unevenness of the roving along the fortress.

Such an implementation of the device makes it possible to use the device to obtain reliable results in studying the joint influence on the process of stretching a roving of two factors — uneven thickness and strength or one of these factors.

FIG. 1 is a schematic front view of the proposed device; on fit. 2 - top view; in fig. 3 is a front view of a detail of the instrument.

In a fixed frame 1, a roller 2 is rotatably mounted, receiving rotation from bar 5.

Above the roller 2 in the basins of the bed is located the roller 4 (opoykovy or metal), kagruzhenny in pins 5 with the lever 6 with the load 7. The lever 6 is connected by a system of rods and levers S with self-writing 9 rotating drum 10, registering on the paper drum uneven roving diameter, exit out of the device.

KC 60384-2 -

The second exhausting pair of rollers // and 12 rotates in movable carriage J3, and the roller // receives rotation from roller 2 through an epicyclic gear with gears M, 15, 16.

Roller 12 is stressed by lever 17 with load 18. Lever 17 is connected by a system 19 and 20 of rods and levers with a recorder 21 of drum 10 for recording a “bridging inbound B” device of a roving through its thickness.

The carriage 13 rolls over the bed / on the rollers 22, 23, 24. Due to the effect of the load 25, -to the hammer to the master 26, which is on the axis 27 of the bed 1, the carriage 13, connected to the link 26, is in the normal position Zvodki between both pairs of rollers. To balance the load 25, a load 29 is intended, attached to the end of the flexible link 30, slung over the block 31 and connected to the carriage 13. The desired degree of stretch in the rim can be set by changing gears 14 and 16.

The end of the rim 26 is equipped with a recorder 32, which records the movement of the carriage on the paper of the rotating drum 33. The size of the weight 25 and the length of the rim 26 are chosen so that slight movements of the carriage 13 (in the order of 1-3 mm) give significant movement of the recorder 32 along the bar ban 33.

When passing weak points, it is strongly stretched under the load. To prevent a quick movement of the skid .13 to the left, a screw 34 interacting by cutting with a gripper 35 of the taller 26 is left. The screw rotates gear 36 from roller 37, driven by rotation of gear 38 and 39 from roller 2, and when interacting with the gripper 35 floats the pattern into the initial position, at which the gripper does not interact with the threading of the screw.

With the passage of steep, strong and the like hard-to-reach sections of the roving, the carriage 13 moves to the right.

The diatra.mma on the paper of drum 33 gives an idea of the degree of unevenness of the roving of the 1 st fortress at a given stretch.

Subject matter

A device for detecting roving irregularities with several pairs of rollers having an increasing circumferential speed and connected to a registering device, characterized in that, in order to determine the unevenness in strength, the rear pair of rollers is mounted on a movable carriage balanced by weights and connected with a lever system with a register uneven strength of the device.
