The output of the mainstream cotton opener on the market is generally around 1000kg / h, while the output of the subsequent cleaning and combing often reaches or even exceeds 2000kg / h. In this case, the method currently adopted by cotton spinning mills is to divide the pipeline behind the bag grabber into two routes, each of which is equipped with a conventional cotton opener, and then merge the output pipelines of the two cotton openers into one pipeline to send to the cotton combing machine. This configuration structure occupies a large space, has complex pipelines, and has high equipment costs.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1-Figure 4 , an embodiment of a cotton feed distribution device of a parallel single-axial flow cotton opener of the present invention comprises a frame, a cotton feed distribution assembly and a controller. A cavity is provided inside the frame, and the cavity comprises a left cavity and a right cavity which are symmetrical on the left and right. The cotton feed distribution assembly comprises a rectangular bend pipe 1, a diverter plate 2, a partition plate 3 and a distribution pipe 5. The rectangular bend pipe 1 is located above the distribution pipe 5. The rectangular bend pipe 1 is connected to the narrow-diameter end of the distribution pipe 5, and the wide-diameter end of the distribution pipe 5 is connected to the cotton feed port. A diverter plate 2 and a partition plate 3 are provided inside the rectangular bend pipe 1 near the distribution pipe 5. An air vent is provided on the top of the diverter plate 2. An air inlet is provided on the side wall of the rectangular bend pipe 1. The height at which the air inlet is provided is between the diverter plate 2 and the partition plate 3. A blowing fan 7 is arranged on the frame, and the blowing fan 7 is connected to the controller. The air outlet of the blowing fan 7 is connected to one end of a blowing pipe 4, and the other end of the blowing pipe 4 is connected to the air inlet hole on the rectangular bend pipe 1, so as to transport the air flow into the cavity in the triangular diverter plate 2, and blow away the raw material 6 accumulated on the top of the diverter plate 2 through the air holes on the diverter plate 2.

[0021] Furthermore, a guide plate is arranged inside the diverter plate 2 to guide the air flow to the air holes of the diverter plate.

[0022] Furthermore, a fan mounting seat 8 is provided on the inner side or the outer side of the frame, and the blower fan 7 is mounted on the fan mounting seat 8 .

[0023] Furthermore, the blowing duct 4 can be made of a plastic tube or a telescopic hose. In addition, the blowing duct 4 can also be composed of two sections of round straight tubes and a section of round curved tube in the middle, such as Figure 1 shown.

[0024] Furthermore, the left vertical plane or the right vertical plane of the splitter plate 2 is connected to the cavity inside the frame, or the bottom of the splitter plate 2 is connected to the cavity inside the frame.

[0025] Preferably, a ventilation plate for removing the cotton inlet airflow is provided in the distribution pipe 5, and a separation plate 3 is provided between the ventilation plate and the diverter plate 2. Through this structural design, the positive pressure airflow in the diverter plate 2 and the exhaust airflow in the distribution pipe 5 can work independently without interfering with each other.

[0026] In addition, it also includes a plug plate, which adjusts the amount of air blown into the inner cavity of the diverter plate 2.

[0027] In order to monitor the accumulation of raw materials on the diverter plate 2 in the rectangular bend pipe 1 and provide an appropriate frequency of the blower fan 7 to save energy, photoelectric sensors 9 are installed on the left and right sides of the rectangular bend pipe 1. The photoelectric sensors 9 are connected to the controller to monitor the accumulation of raw materials 6 on the diverter plate 2 and control the frequency of the blower fan 7 according to the monitoring results.

[0028] The above-mentioned photoelectric sensor 9 includes a plurality of photoelectric emitting components and photoelectric receiving components. When the photoelectric sensor 9 is specifically set, a plurality of photoelectric emitting components and photoelectric receiving components are respectively installed in a matrix manner on the left and right sides of the rectangular bend tube 1. The height and width of the positions of the photoelectric emitting components and the photoelectric receiving components are consistent, and the height distribution range is: the photoelectric emitting components and the photoelectric receiving components at the highest point are higher than the top of the diverter plate 2, and the photoelectric emitting components and the photoelectric receiving components at the lowest point are slightly higher than the top of the diverter plate 2. In this way, the accumulation of the raw material 6 on the diverter plate 2 can be better collected.

[0029] An embodiment of a control method for the cotton feeding and distributing device of the parallel single-axial flow cotton opener of the present invention comprises the following steps: Step 1: Feed the raw material 6 into the rectangular bend tube 1 from the upper inlet. During the falling process in the rectangular bend tube 1, the raw material 6 is divided by the diverter plate 2 and enters the left cavity and the right cavity; Step 2: The controller monitors the accumulation of the raw material 6 on the diverter plate 2 through the photoelectric sensor 9. The controller collects the signal output by the photoelectric sensor 9 and determines the height value of the raw material on the diverter plate 2. Step 3: When the height of the raw material 6 on the diverter plate 2 is lower than the set value, the controller transmits a signal to the blower fan 7 to operate at a lower frequency; when the height of the raw material 6 on the diverter plate 2 is higher than the set value, the controller transmits a signal to the blower fan 7 to operate at a higher frequency.

[0030] When there is no accumulated raw material 6 on the diverter plate 2, the blower fan 7 can be controlled to operate at the lowest frequency, or even the operation of the blower fan 7 can be suspended, so as to better save energy.

[0031] In addition, a raw material excess height value can be set in the controller. When the height of the raw material 6 accumulated on the diverter plate 2 reaches the set raw material excess height value and continues for a period of time, the controller can control the equipment to alarm and conduct personnel intervention to avoid malfunctions.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
