Description

Technical Field

[0002] Foreign fibers are impurities in cotton. On bleached fabrics, they appear as red or blue spots, which have a great impact on the appearance of bleached fabrics. When removing foreign fibers, the foreign fibers are entangled with the internal silk threads of the cotton, and the cotton is difficult to flatten. A large amount of cotton has been entangled together, which increases the difficulty of separating the foreign fibers from the cotton, resulting in a large amount of cotton being removed when removing the foreign fibers, reducing the cotton yield.

[0063] During operation, cotton flows in the cotton material channel 2, the lamp is lit to generate light, and the light acts on the cotton and foreign fibers through the glass 312. At this time, the cotton and foreign fibers present different colors. At the same time, the camera 3133 works, and the image information of the cotton and foreign fibers is collected by the camera 3133 through the reflection of the reflector 3134. Since two detection components 31 are set, the foreign fibers in the cotton are collected twice at different positions. According to the distance between the two collection positions and the two collection times, the flow rate of the foreign fibers can be calculated;

The plurality of solenoid valves 4132 are arranged side by side. A plurality of jet holes 4133 are provided on the valve seat 4131. The plurality of jet holes 4133 correspond to the plurality of solenoid valves 4132 one by one. The solenoid valves 4132 are used to control the jet holes 4133 to eject air.

[0069] The jet side of the gas valve seat 4131 is sealed with a nozzle plate 4134, and the nozzle plate 4134 is provided with a plurality of groups of equal flow holes 4135, and the plurality of groups of equal flow holes 4135 correspond to the plurality of jet holes 4133 one by one. A connecting groove 4136 is provided at the jet end of the jet hole 4133, and a sealing ring 4137 is provided in the connecting groove 4136. The jet hole 4133 is connected with the equal flow holes 4135 of the same group through the connecting groove 4136.

[0070] Each group of flow balancing holes 4135 is provided with four, and the four flow balancing holes 4135 in the same group are arranged side by side;

[0071] The collecting assembly 42 includes a foreign fiber flow channel 421 and a fan 422, the input end of the foreign fiber flow channel 421 is in contact with the cotton material channel 2, and the output end of the foreign fiber flow channel 421 is connected to the input end of the fan 422;

[0072] The foreign fiber flow channel 421 includes a main body 4211 and a connecting portion 4212, the connecting portion 4212 is slidably connected to the main body 4211, the connecting portion 4212 and the main body 4211 are locked by a locking member, the locking member can be a bolt, loosen the bolt, so that the connecting portion 4212 moves on the main body 4211, so as to facilitate the adjustment of the installation position of the foreign fiber flow and the cotton material channel 2, after the installation is completed, tighten the bolt to achieve the fixation between the main body 4211 and the connecting portion 4212;

[0073] The collecting assembly 42 further includes a drop pipe 423, which is arranged vertically, and the top of the drop pipe 423 is sealed, and the drop pipe 423 is connected to the output end of the fan 422 through a connecting pipe 424;

[0074] When the foreign fibers flow to the rejecting mechanism 4, the electromagnetic valve 4132 at the corresponding position is opened, and the air in the gas tank is delivered to the gas valve seat 4131, so that the jet hole 4133 delivers the air from the connecting groove 4136 to the flow-equalizing hole 4135, and the flow-equalizing hole 4135 then discharges the air. In fact, an air blowing port is provided on the cotton material channel 2, and the foreign fibers flow is connected to the cotton material channel 2. The air discharged from the flow-equalizing hole 4135 acts on the foreign fibers through the air blowing port, so that the foreign fibers are removed under the action of the air flow. The foreign fibers in the foreign fiber flow channel 421 are blown to the foreign fiber flow channel 421. At the same time, the fan 422 is started to transport the air in the foreign fiber flow channel 421 to the fan 422. The air in the fan 422 is then transported from the connecting pipe 424 to the drop pipe 423. Under the action of the airflow, the foreign fibers in the foreign fiber flow channel 421 enter the drop pipe 423 along with the air. A receiving device is connected to the bottom end of the drop pipe 423. The foreign fibers fall into the receiving device under the action of gravity, so that the foreign fibers are removed and collected.

[0075] Working principle:

[0076] The input end of the cotton material channel 2 is connected to the carding machine. After the cotton material discharged by the carding machine is transported to the cotton material channel 2, the cotton material flows upward at an angle in the cotton material channel 2 and is discharged from the output end of the cotton material channel 2.

[0077] During the flow of cotton material, firstly, the camera 3133 is used to collect image information of foreign fibers in the cotton material twice at different times and different positions. According to the distance between the two collection positions and the two collection times, the flow rate of foreign fibers can be calculated. Then, according to the flow rate of foreign fibers, the electromagnetic valve 4132 at the corresponding position is controlled to open after a set time, so that the air in the air valve seat 4131 is discharged and acts on the foreign fibers. The foreign fibers are blown to the foreign fiber flow channel 421 under the action of the airflow. At the same time, the fan 422 is started to transport the air in the foreign fiber flow channel 421 to the fan 422, and the air in the fan 422 is then transported from the connecting pipe 424 to the blanking pipe 423. Under the action of the airflow, the foreign fibers in the foreign fiber flow channel 421 enter the blanking pipe 423 along with the air, so that the bottom end of the blanking pipe 423 is connected to a receiving device, and the foreign fibers fall into the receiving device under the action of gravity, so as to realize the removal and collection of foreign fibers.

[0078] To summarize, according to the time when the camera 3133 captures the foreign fiber image, the rejection mechanism 4 performs the foreign fiber rejection action after the set time, and the foreign fiber flow velocity can be calculated according to the distance between the two acquisition positions and the two acquisition times. The time when the rejection mechanism 4 performs the foreign fiber rejection action can be more accurately calculated based on the foreign fiber flow velocity, thereby improving the accuracy of foreign fiber rejection, that is, improving the stability of the foreign fiber machine's cleaning effect. Moreover, in the process of executing the foreign fiber rejection action, the collection of foreign fibers can also be achieved.

[0079] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
