BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning device for spinning viscous liquids with simple clamping of the spinning blocks into a spinning device.

The prior art designs of spun spinning devices have been solved from the point of deposit of the nozzle blocks to the device by means of a method, i.e., from the mountain or from the bottom.

Large-weight nozzle blocks, as well as silk-type nozzle blocks, or nozzle blocks with two-way feeders for two-component spinning are clamped to the feed production channel preferably by a single pressure screw, the nozzle blocks being a spinning spinner. u-posed from the mountain.

The disadvantage of this design is the necessity of removing the upper insulating covers during the cyclic exchange of the nozzle blocks, where considerable loss of energy occurs due to the leakage of heat, which is related to the so-called chimney unwanted, since during the exchange of the nozzle blocks the water spinning device is continuously opened at working temperatures. The burners air upwards together with the sex-blowers, aggravates the operator's environment, makes it difficult to handle the nozzle blocks. A serious disadvantage of the design of the device in which the nozzle blocks are deposited is the need for fixed or movable handling platforms. Stairs and ladders to the handling platforms on which the service moves with heated nozzle blocks can be a source of injury.

However, the spinning device into which the nozzle blocks are deposited is advantageously disadvantaged, however, by the difficult clamping of the nozzle blocks in the ergonomically disadvantageous position of the clamping screws.

Prior art solutions for distribution spinning devices are known, in which the clamping of nozzle blocks of the Cs-type is realized. AO 183 278. Said solution is suitable only for large-capacity spinning blocks with a long-term exchange cycle of the use of crane technology.

It is also known to deposit nozzle blocks in a spinning apparatus of sub-section AO 187 973, wherein the nozzle block cylinder is inserted into the fork lever and rotated to fix it against the spinning device. The solution could not be used for rectangular nozzle blocks, which are preferably made of fiber cross-section.

Known is the device according to the invention DD153140, which only serves for the assembly and de-assembly of nozzle blocks on a mounting plate. The device cannot be used to mount the nozzle blocks to the spinning device.

A spinning device according to CSA 242 244 is known, where the nozzle block is placed in the device from below and is sealed to the supply channel by means of a mechanism consisting of a movable dowel, a rod and a clamp into which the nozzle block is attached. with fixing pins. The present invention represents a considerable degree of mechanization, but this solution can not be used, for example, in single-piece spinning devices where the inlet throats interfere with the location of the clamping mechanism.

The present disadvantages are avoided by the novel solution of the spinning device with simple and reliable clamping of the block blocks according to the invention.

The fiber spinning apparatus of the present invention is provided with a blast-block retainer, wherein the nozzle block is sealed with at least one clamping screw by the discharge production channel. The clamping screw can be twisted by tightening the pneumatic tightening unit while tightening it. , or transferred to the head of the clamping screw. The tightening unit is provided with adjustable torque and reversing. The traps serve to catch the nozzle block and prevent it from falling off when the clamping screw is released. Scanning of the nozzle block is carried out by means of a slide-out jig for retractable clamps. The advantages of the solution according to the invention can be seen in the accompanying drawings, in which Fig. 1 shows a cross section of a spinning device in which the nozzle block is clamped to the supply channel by a side clamping screw and Fig. 2 shows the types of nozzle with the nozzle by a block clamped to the supply channel from the bottom side by at least one clamping screw.

In Fig. 1, the spinning device 100 is provided with grippers 120 to grip the nozzle block 110, which is secured to the discharge product channel 102 of the spinning device and sealed by the clamping screw 132 which is clamped by the tightening unit 150.

In Fig. 2, the spinning device 100 is provided with grippers 120 to grip the nozzle block 110, which is secured to the discharge spinner 102 and sealed by clamping screws 132 which are tightened by a non-pneumatic tightening unit. The gripper 120 consists of a latch 121 which is slidably supported in the bracket 122. A spring 123 is provided on the latch 121, the pressure of which can be adjusted by the screw 124. The bracket 122 with the latch 121 is attached to the spinning apparatus 100 by screws 125.
