Description

Technical Field

[0001] This invention belongs to the field of textile machinery manufacturing technology, specifically a parallel single-axis flow cotton opener cotton feeding distribution device and control method. Background Technology

[0002] The cotton opener, as the main equipment of the opening and carding combined machine, is used to initially open and remove impurities from raw cotton of various compositions for use in the next process. Currently, the output of mainstream cotton openers on the market is generally around 1000 kg / h, while the output of subsequent opening and carding combined machines often reaches or even exceeds 2000 kg / h. In this case, the common method used by cotton mills is to split the pipeline after the baler into two lines, with each line equipped with a conventional cotton opener, and then merge the output pipelines of the two cotton openers into one pipeline to send the cotton to the carding machine. This configuration structure occupies a large space, has complex pipelines, and has high equipment costs.

[0003] Chinese Patent (Patent No.: ZL201810742649.9) discloses a parallel single-axis flow cotton opener, including a frame, a cotton inlet distribution assembly, a guide hood, a beater assembly, a dust bar assembly, a cotton drop trolley assembly, a drive assembly, and a controller. The frame has an internal cavity, which includes a left cavity and a right cavity that are symmetrically arranged. The guide hood includes a left guide hood and a right guide hood that are symmetrically arranged. The cotton inlet distribution assembly connects the cotton inlet of the left guide hood and the cotton inlet of the right guide hood. The beater assembly, dust bar assembly, cotton drop trolley assembly, and drive assembly are disposed in the cavity of the frame. The controller is fixed on the frame and is connected to the drive assembly. The drive assembly is connected to the beater assembly and is used to drive the beater assembly to operate. The cotton feeding and distribution assembly includes a round-square tube, a rectangular bend tube, and a conical cotton distribution tube. The round-square tube has a circular inlet and a square outlet. The square outlet is connected to one end of the rectangular bend tube, and the other end of the rectangular bend tube is connected to the narrow-diameter end of the conical cotton distribution tube. The wide-diameter end of the conical cotton distribution tube is connected to the cotton inlet. A triangular baffle is provided in the center of the rectangular bend tube, and an airflow separator is provided in the center of the conical cotton distribution tube. This patent has a compact structure and reasonable design, including an opening and impurity removal system for two single-axial flow cotton openers, which can meet the requirements of output above 2000kg / h and up to 3000kg / h. It occupies little space, has simple piping, and low equipment configuration costs.

[0004] The above-mentioned patented technologies have the following problems in actual production applications: When the cotton grabbing machine grabs a large amount of cotton, some raw material will accumulate on the upper part of the triangular baffle in the cotton inlet bend, which serves as a diversion plate; as time goes by, the raw material gradually accumulates into a large volume and the diversion plate cannot accommodate it, and the large clump of raw material enters the beater chamber of the axial flow cotton opener as a whole; the above-mentioned large clump of raw material will cause uneven opening of raw material and poor impurity removal effect, and in severe cases, the beater will be overloaded, causing an alarm and shutdown.

[0005] How to solve the problems of uneven opening and poor impurity removal caused by large clumps of raw materials, and avoid alarm shutdowns caused by excessive load on the beater due to large clumps of raw materials, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides a parallel single-axis flow cotton opener cotton feeding and distribution device and control method, which can solve the problems of uneven opening and poor impurity removal caused by large clumps of raw materials, and avoid alarm shutdowns caused by excessive load on the beater due to large clumps of raw materials.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A parallel single-axial flow cotton opener cotton feeding distribution device includes a frame, a cotton feeding distribution assembly, and a controller. The frame has an internal cavity comprising a left cavity and a right cavity, symmetrically arranged. The cotton feeding distribution assembly includes a curved tube, a flow divider plate, a partition plate, and a distribution pipe. The curved tube connects to the narrow-diameter end of the distribution pipe, and the wide-diameter end of the distribution pipe connects to the cotton inlet. The flow divider plate and partition plate are disposed inside the curved tube near the distribution pipe. The flow divider plate has a permeable surface at its top. An air inlet is provided on the side wall of the rectangular bend tube. The height of the air inlet is located between the flow divider plate and the isolation plate. A blower is provided on the frame and is connected to the controller. The air outlet of the blower is connected to one end of a blower pipe, and the other end of the blower pipe is connected to the air inlet on the rectangular bend tube. This is used to deliver airflow into the triangular cavity of the flow divider plate and to blow away the raw material accumulated on top of the flow divider plate through the air vents.

[0009] Improvement to the above technical solution: A guide plate is provided inside the flow divider to guide the airflow to the air vents of the flow divider.

[0010] A further improvement to the above technical solution: a fan mounting base is provided on the inner or outer side of the frame, and the blower is mounted on the fan mounting base.

[0011] Further improvement to the above technical solution: The air blowing duct is made of plastic or a flexible hose.

[0012] Further improvement to the above technical solution: The air blowing duct is composed of two straight circular pipes and one curved circular pipe in the middle.

[0013] A further improvement to the above technical solution: the left or right vertical plane of the diverter plate is connected to the cavity, or the bottom of the diverter plate is connected to the cavity.

[0014] Further improvement to the above technical solution: A ventilation plate for discharging the airflow into the cotton is provided inside the distribution pipe, and the isolation plate is provided between the ventilation plate and the diversion plate.

[0015] Further improvements to the above technical solution include an insert plate, which regulates the airflow into the inner cavity of the splitter plate.

[0016] Further improvements to the above technical solution: Photoelectric sensors are installed on both the left and right sides of the rectangular bend tube. The photoelectric sensors are connected to the controller to monitor the accumulation of raw materials on the diversion plate and control the frequency of the blower based on the monitoring results.

[0017] The present invention discloses a control method for a parallel single-axial flow cotton opener cotton feeding and distribution device, characterized in that the control method includes the following steps:

[0018] Step 1: Feed the raw material into the tube from the upper inlet. As the raw material falls into the tube, it is diverted by the flow divider and enters the left and right cavities.

[0019] Step 2: The controller monitors the accumulation of raw materials on the diversion plate through photoelectric sensors. The controller collects the signals output by the photoelectric sensors and determines the height of the raw materials on the diversion plate.

[0020] Step 3: When the material height on the distributor plate is lower than the set value, the controller sends a signal to the blower to operate at a lower frequency; when the material height on the distributor plate is higher than the set value, the controller sends a signal to the blower to operate at a higher frequency.

[0021] The advantages and positive effects of this invention are:

[0022] 1. This invention delivers airflow into the manifold cavity via a blower. The airflow passes through the vents on the manifold and can promptly disperse the raw material accumulated on the upper part of the manifold, thus preventing large clumps of raw material from entering the beater cavity and causing malfunctions such as shutdown.

[0023] 2. This invention can make the raw materials entering the left and right cavities of the parallel axial flow cotton opener more uniform, so as to achieve the ideal opening and impurity removal effect.

[0024] 3. The present invention has a simple structure, is easy to install, has low cost, and is easy to modify and promote on existing equipment;

[0025] 4. This invention installs photoelectric sensors on both the left and right sides of the rectangular bend tube. The controller collects the signals output by the photoelectric sensors and adjusts the operating frequency of the blower accordingly based on the height of the raw material accumulated on the distribution plate. This avoids both excessive blower force, which could cause the accumulated raw material on the distribution plate to flow back upwards and affect the normal descent of the raw material just entering the rectangular bend tube, and insufficient blower force, which could prevent the accumulated raw material from being blown off the distribution plate. Furthermore, it is beneficial for energy saving and consumption reduction. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings:

[0032] See Figures 1-4 This invention discloses an embodiment of a parallel single-axial flow cotton opener cotton feeding distribution device, comprising a frame, a cotton feeding distribution assembly, and a controller. The frame contains a cavity, including a left cavity and a right cavity symmetrically arranged. The cotton feeding distribution assembly includes a rectangular bend pipe 1, a flow divider plate 2, an isolation plate 3, and a distribution pipe 5. The rectangular bend pipe 1 is located above the distribution pipe 5, connecting to the narrow-diameter end of the distribution pipe 5, while the wide-diameter end of the distribution pipe 5 connects to the cotton inlet. The flow divider plate 2 and the isolation plate 3 are positioned inside the rectangular bend pipe 1 near the distribution pipe 5. A vent is provided at the top of the flow divider plate 2, and an air inlet is provided on the side wall of the rectangular bend pipe 1, the air inlet being positioned between the flow divider plate 2 and the isolation plate 3. A blower 7 is installed on the frame and connected to the controller. The air outlet of the blower 7 is connected to one end of a blower pipe 4, and the other end of the blower pipe 4 is connected to the air inlet on the rectangular bend pipe 1. The blower 7 is used to deliver airflow into the cavity inside the triangular diverter plate 2 and to blow away the raw material 6 accumulated on top of the diverter plate 2 through the vent holes on the diverter plate 2.

[0033] Furthermore, a guide plate is provided inside the aforementioned diverter plate 2 to guide the airflow to the air vents of the diverter plate.

[0034] Furthermore, a fan mounting base 8 is provided on the inner or outer side of the aforementioned frame, and the blower 7 is mounted on the fan mounting base 8.

[0035] Furthermore, the aforementioned air duct 4 can be made of plastic or a flexible hose. Alternatively, the aforementioned air duct 4 can also be composed of two straight circular pipes and a central curved circular pipe, such as... Figure 1 As shown.

[0036] Furthermore, the left or right vertical plane of the aforementioned diverter plate 2 is connected to the cavity inside the frame, or the bottom of the diverter plate 2 is connected to the cavity inside the frame.

[0037] Preferably, a ventilation plate for discharging the incoming airflow is provided inside the distribution pipe 5, and an isolation plate 3 is provided between the ventilation plate and the diversion plate 2. Through this structural design, the positive pressure airflow in the diversion plate 2 and the exhaust airflow in the distribution pipe 5 are cleverly made to work independently and without interference.

[0038] Additionally, it includes an insert plate, which adjusts the airflow into the inner cavity of the splitter plate 2.

[0039] In order to monitor the raw material accumulation on the diversion plate 2 inside the rectangular bend 1 and provide an appropriate frequency for the blower 7 to save energy, photoelectric sensors 9 are installed on both sides of the rectangular bend 1. The photoelectric sensors 9 are connected to the controller to monitor the accumulation of raw material 6 on the diversion plate 2 and control the frequency of the blower 7 according to the monitoring results.

[0040] The aforementioned photoelectric sensor 9 includes several photoelectric emitting components and photoelectric receiving components. Specifically, when setting up the photoelectric sensor 9, several photoelectric emitting components and photoelectric receiving components are installed in a matrix on both sides of the rectangular bend tube 1. The height and width of the photoelectric emitting and receiving components are the same, and the height distribution is as follows: the highest photoelectric emitting and receiving components are above the top of the diverter plate 2, and the lowest photoelectric emitting and receiving components are slightly below the top of the diverter plate 2. This allows for better acquisition of the accumulation of raw material 6 on the diverter plate 2.

[0041] An embodiment of the control method for the above-mentioned parallel single-axial flow cotton opener cotton feeding and distribution device of the present invention includes the following steps:

[0042] Step 1: Feed the raw material 6 into the upper inlet of the rectangular bend tube 1. As the raw material 6 falls into the rectangular bend tube 1, it is diverted by the diverter plate 2 and then enters the left and right cavities.

[0043] Step 2: The controller monitors the accumulation of raw material 6 on the diversion plate 2 through photoelectric sensor 9. The controller collects the signal output by photoelectric sensor 9 and determines the height value of raw material on diversion plate 2.

[0044] 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 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 to operate at a higher frequency.

[0045] When there is no raw material 6 accumulating on the diverter plate 2, the blower 7 can be controlled to operate at the lowest frequency, or even the blower 7 can be stopped to save energy.

[0046] In addition, a raw material over-height value can be set in the controller. When the height of the raw material 6 accumulated on the diversion plate 2 reaches the set raw material over-height value and continues for a period of time, the controller can control the equipment to alarm and allow personnel to intervene in order to prevent malfunctions.

[0047] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
