Abstract

The invention relates to spinning the textile industry and can be used in the preparation of a mixture of fibrous materials. The purpose of the invention is to increase the mixing efficiency. The mixing machine has several bunkers with discharge and loose rollers. The rollers serve to discharge the fibrous material from the bins at different speeds onto a common conveyor, where the fibrous material is mixed. The plane of the axes of the discharge rollers is an angle of less than 90 ° to the horizontal, thereby improving the quality of mixing. 2 Il.

WITH

The invention relates to the spinning production of the textile industry and can be used in the preparation of a mixture of fibrous materials.

The aim of the invention is to increase the mixing capacity of the device.

The stated goal is achieved by that. that in a mixing machine containing bunkers equipped with discharge and loosening rollers installed with the possibility of discharging material from bunkers at different speeds onto a transporting device located horizontally under the bunkers, the discharge and loosening rollers are located at an angle less than 90 ° to the transporting device.

The location of the discharge and loosening rollers at an angle of less than 90 ° to the conveyor, and hence to the direction of movement of the material in the bins, allows simultaneous selection of several horizontal layers of fibrous material from each bunker, thereby increasing the mixing capacity of the machine, as in any unit time in the fibrous material supplied to the conveyor from each bunker, there are scraps of several horizontal layers.

In the device, the fibrous material is fed to the conveyor from the bins already mixed and continues to be mixed on the conveyor.

FIG. 1 shows a mixing machine in isometry; in fig. 2 - the same, longitudinal section.

The mixing machine consists of hoppers 1. fed from a common pneumatic duct 2. The hoppers have perforated windows at the top 3. The discharge rollers are installed at the bottom of an acute angle to the horizontal 4. Of the exhaust rollers

the fibrous material goes to the loose rollers 5, then to the common conveyor 6 and gave it to the pneumatic line 7 to the subsequent machine.

The mixing machine works as follows.

Through the common supply feed line 2, the fiber-air mixture enters the hoppers 1. Air is removed through the perforated windows 3. An oblique pair of discharge rollers 4 feeds the fibrous material from the hopper 1 saping roller 5, which separates the resulting material into individual scraps collected on the conveyor 6 The material is then discharged along the pneumatic line 7 from the mixing machine. Rollers 4 and 5 are located at an acute angle to the horizontal and direction of movement of the fibrous material about the bins. Selection is made simultaneously from several horizontal layers of fibrous material. An increase in the mixing capacity of the device is ensured, since the fibrous material is already mixed onto the conveyor from the bins, and is additionally mixed on the conveyor.
