Description

Technical Field

[0001] This utility model relates to the field of textile industry technology, and in particular to a pulse cleaning device based on the impurities falling from a combing machine. Background Technology

[0002] Currently, the mainstream practice in factories to handle debris falling onto combing machines is to create a long, narrow funnel with a wider top and narrower bottom. The opening is connected to a ditch, and the debris is then sucked away through the ditch. However, because the machine has steep sides, debris easily accumulates on the sloping surface of the suction funnel. Moreover, digging the ditch requires a large amount of manpower and poses certain fire safety hazards. Furthermore, the precision requirements for digging the ditch vary depending on the construction stage, which can affect the stability of subsequent equipment installation and operation. In addition, the existing method is difficult to modify combing machines that have already been assembled according to requirements. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a pulse cleaning device for impurities falling into a combing machine. The pulse cleaning device is designed to address the accumulation of impurities during the production process of the combing machine. The pulse cleaning device is set up based on the on-site environment of the combing machine and includes a pneumatic blowing point module, a fan recovery module, and a main control module. The pneumatic blowing point module also includes a PU air pipe, an electromagnetic pulse valve, and blowing points. The blowing points are set at each point on the combing machine where impurities are easily falling into the machine. At the same time, one end of the blowing point is connected to the air outlet of the electromagnetic pulse valve by a thread. The air inlet of the electromagnetic pulse valve is connected to a PU air pipe, and the tail end of the PU air pipe is connected to a pressurized air source. The pneumatic blowing point module has several groups and adopts a parallel structure. Each branch PU air pipe is connected to the main line by a T-connector.

[0004] The blower recovery module is located in the hemp drop channel downwind of the pneumatic blowing point module. The hemp drop channel is constructed based on the on-site assembly and modification requirements of the combing machine. A hemp drop channel plate is installed on the hemp drop channel. The blower recovery module includes a suction port, a dust collection pipe, and a dust collection fan. The suction port is located in the hemp drop channel and is flush with the hemp drop channel plate in the vertical direction. The suction port and the hemp drop channel plate are simultaneously adjusted for tilt at fixed points using a swaying joint or hinge. The suction port is connected to the dust collection fan via the dust collection pipe, and a dust collection bag is fitted at the outlet of the dust collection fan.

[0005] The main control module is driven by a PLC. The electromagnetic pulse valve in the pneumatic blowing module and the dust collection fan in the fan recovery module are connected to the main control module through a communication bus and electrical lines. The main control module is located in the safety electrical control box on site.

[0006] In one embodiment of this utility model, the electromagnetic pulse valve adopts a fixed base, which is set on the housing of the combing machine or on the side wall of the site; and both ends of the electromagnetic pulse valve are provided with threaded straight quick connectors, which are connected to the PU air pipe and the blowing point respectively.

[0007] In one embodiment of this utility model, the dust extraction fan is a 15kW fan, and the main control module records the fan's operating load to realize the calculation and real-time monitoring of the amount of hemp falling on site.

[0008] In one embodiment of this utility model, the suction port adopts an adjustable funnel device, and a rocking joint component is provided at the lower end of the suction port. The rotating shaft in the rocking joint component rotates to make the suction port have different tilt angles, so as to prevent hemp from accumulating at the suction port.

[0009] In one embodiment of this utility model, the surface panel of the electrical control box is provided with start and stop function buttons for the main control module, as well as a pulse cleaning operation indicator and an operation screen.

[0010] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0011] First, it can achieve ground cleaning even in factories where digging trenches is not feasible. Second, it allows for separate control of each debris accumulation point. Third, it facilitates centralized collection and cleaning of debris through a vacuum pipe, enabling recyclable operations. Fourth, it is easy to move; when a factory needs renovation, this device can be easily relocated without requiring extensive civil engineering work. Fifth, it facilitates inspection in case of malfunctions, easily locating accumulation points for convenient cleaning. Sixth, it requires minimal manual labor for construction.

[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a pulse cleaning device for cleaning debris accumulated during the combing machine production process. The pulse cleaning device is designed to address the accumulation of debris during combing machine production. Each debris accumulation point on the combing machine is equipped with a blowing point, and each blowing point is equipped with an electromagnetic pulse valve (1 / 2″ internal thread pipe interface, one inlet and one outlet). The electromagnetic pulse valve is positioned next to the blowing point and connected to compressed air (0.6–1 MPa). The inlet of the electromagnetic pulse valve is connected to a PU (polyurethane) pipe for compressed air, and the outlet is connected to a PU pipe to the blowing point. The blowing angle of the PU pipe can be rotated and adjusted for convenient multi-angle cleaning of the debris.

[0018] One end of the hemp drop channel is connected to the suction pipe. The hemp drop channel plate is fixed with a rotatable and adjustable fixing device. The tilt can be adjusted according to the height and angle of the suction port and the hemp drop situation, making it easier for impurities to enter the suction port.

[0019] Based on the calculation and real-time monitoring of the amount of fallen hemp, a 15kW fan is connected to the dust collection duct, and a dust collection bag is fitted at the air outlet to facilitate the collection of fallen hemp and achieve waste recycling. The suction port adopts an adjustable funnel device, and a rocking joint component is set at the lower end of the suction port. The rotating shaft in the rocking joint component allows the suction port to have different tilt angles, preventing the accumulation of fallen hemp at the suction port.

[0020] Simulating the hemp shedding situation, compressed air is used to clean it, and the maximum collection amount can reach 3-3.5 kg / time.

[0021] like Figure 2 As shown, the pulse cleaning device described in this embodiment operates as follows: the solenoid valve pulses to open and close the compressed air, and the compressed air is blown out from the blowing point. The dust and debris accumulated at the blowing point are blown to the next blowing point by the compressed air blown out by the pulse. The four blowing points relay the blowing, and the last blowing point blows the dust to the suction port of the dust collection pipe. The other end of the dust collection pipe is connected to the dust collection fan.

[0022] Furthermore, Figure 2 The electrical power supply section of the dust collection pulse cleaning device involves both AC 220V and AC 380V. AC 220V powers some control circuits, such as control relays (KA) and other components. AC 380V primarily powers the higher-powered vacuum cleaner fan. Additionally, there is a +24V DC power supply to power devices requiring DC power, such as PLCs (Programmable Logic Controllers), ensuring their stable operation.

[0023] Meanwhile, multiple fuses (FUs) are installed in the power supply line, such as FU1, FU2, FU3, and FU4, to promptly disconnect the circuit and protect the equipment in the event of an overload or short circuit. For example, FU2 is used to protect the circuit branch related to the vacuum cleaner fan, preventing excessive current from damaging other components due to fan failure.

[0024] It also includes a control element section, containing multiple control relays (KA1-KA5), which function as converters and amplifiers of control signals in the circuit. For example, KA5 may be used to control the overall power supply of the entire pulse cleaning device; when KA5 is energized and engaged, the entire device is powered on and begins to work. KA1-KA4 correspond to four electromagnetic pulse valves, respectively, used to control the blowing action of each blowing point.

[0025] The operating buttons include a start button (SB1), a stop button (SB2), and a selector switch (SA1). The start button is used to start the entire device; pressing it activates the control circuit and enables the relevant equipment to operate. The stop button is used for emergency shutdown of the device, ensuring that the power can be quickly cut off when needed. The selector switch (SA1) is used to switch the device's operating mode, such as between manual and automatic modes.

[0026] The operation indicator light (HL1) is used to indicate the operating status of the device. When the device is operating normally, the indicator light will light up, allowing operators to intuitively understand the working status of the device.

[0027] The electromagnetic pulse valve and vacuum blower control section, including the control circuit of the electromagnetic pulse valves (YV1-YV4, corresponding to KA1-KA4 control in the diagram), is connected to the PLC. The PLC outputs signals to control the on / off state of the electromagnetic pulse valves, thereby controlling the airflow at the blowing point. The inlet of the electromagnetic pulse valve is connected to a PU air pipe for compressed air, and the outlet is connected to a PU air pipe to the blowing point. The blowing time is adjusted by controlling the on / off time of the electromagnetic pulse valve (adjustable from 0-60s, setpoint: 3 seconds).

[0028] The vacuum cleaner (M) is electrically controlled and connected to the power supply circuit. Its operation is also monitored and controlled by the PLC. The vacuum cleaner has a power of 15kW. It sucks in the blown-up hemp through the suction pipe, and a dust collection bag is placed at the air outlet to collect the hemp.

[0029] Meanwhile, the main control module operates on the following automatic control principle: the electromagnetic pulse valve and the vacuum fan are electrically controlled, running intermittently. The blowing time is adjustable from 0 to 60 seconds, and the interval time is adjustable from 0 to 1200 seconds. The four blowing points can be individually controlled (set and adjusted) for blowing and interval time. When switching to manual mode, a single electromagnetic valve can be activated to handle the landing point situation.

[0030] Therefore, this utility model abandons the traditional method of digging ditches to clean debris from the combing machine, and adopts a cleverly designed automatic blowing cleaning method, which makes cleaning and collection more convenient and the device simpler. Figure 3As shown, the electromagnetic pulse valve and the dust extraction fan are electrically controlled and operate intermittently. The operation and stop time of each valve can be changed to meet the needs of various types of hemp, different hemp dropping amounts on different machines, different hemp dropping amounts at different blowing points on the same machine, and inconsistent cleaning times.

[0031] Figure 3 The power supply section of a PLC:

[0032] L1 and N: These are the phase line (L1) and neutral line (N) of the AC power input, providing power support for the entire PLC control system. Typically, after the AC power is connected, it undergoes a series of processes, such as voltage reduction, rectification, and filtering, to provide a stable DC operating voltage for the various modules within the PLC.

[0033] PE: Protective grounding terminal, used to connect conductive parts such as the metal casing of equipment to the earth to ensure the safety of personnel and equipment in the event of an electrical fault. When leakage occurs inside the equipment, the current can flow to the earth through the protective grounding path, avoiding the risk of electric shock.

[0034] +24V, 0V: These are commonly used DC power outputs in PLC systems. +24V is the positive voltage output terminal, and 0V is the reference ground (negative terminal). This DC power supply provides operating power for the PLC's input / output modules, internal circuits, and some external sensors and actuators. For example, some proximity switches and photoelectric sensors may require a +24V power supply to function properly, and their signal outputs communicate with the PLC based on the level changes between +24V and 0V.

[0035] Input / output interface section:

[0036] DIa and DIb (digital input points) are the input interfaces for the PLC to receive external digital signals. These input points can be connected to various switching signal devices, such as buttons (e.g., start button SB1E, stop button SB2E, etc.), limit switches, and the switching outputs of sensors.

[0037] Each input point has a corresponding number. For example, DIA may contain multiple input channels, numbered DIA.0, DIA.1, DIA.2, etc., and the same applies to DIB. When the status of an externally connected device changes (such as a button being pressed or released), the level of the corresponding input point will change (usually to a high or low level). The PLC detects these level changes to obtain the status information of the external device, and then performs corresponding control operations according to the program logic.

[0038] DOa (Digital Output Point):

[0039] DOa is the interface used by the PLC to output control signals, which are used to control external actuators, such as relays (KA1-KA6), electromagnetic pulse valves (YV1-YV4), indicator lights (HL1), etc.

[0040] Similar to input points, DOa also contains multiple output channels, numbered DOa.0, DOa.1, DOa.2, etc. When the PLC program needs to control the action of a certain actuator according to the control logic, it will output a control signal (such as a high level or a low level) on the corresponding output channel. This signal drives an external relay or other power amplifier circuit, energizing or de-energizing the actuator, thereby controlling the equipment. For example, when DOa.0 outputs a high level, it may energize and engage the relay KA1 that controls the first electromagnetic pulse valve (YV1), thus opening YV1 and performing a blowing operation.

[0041] The PLC main unit is the core component of the entire PLC control system, and it uses the CPU SR30; M (memory area): used to store user programs, system configuration data, intermediate variables and other information; L+ (internal power positive terminal): is the positive terminal inside the PLC used to provide power to some modules (such as input and output modules).

[0042] Other features include a RUN indicator light: used to indicate the PLC's operating status, specifically the pulse cleaning indicator. When the PLC is running normally, the RUN indicator light will illuminate, usually green. Operators can quickly determine if the PLC is operating normally by observing the RUN indicator light. If the RUN indicator light is off, it may indicate a PLC malfunction, such as a power supply problem, program error, or hardware failure, requiring further inspection and troubleshooting.

[0043] TEST (Test Indicator or Test Port): This may be used for testing and debugging functions of the PLC system. During equipment debugging or troubleshooting, you can obtain information about the PLC's internal operating status or signal transmission by connecting external test equipment to the TEST port or observing the status of the TEST indicator, helping technicians quickly locate the problem.

[0044] In summary, the PLC program implements the intermittent operation control logic for the electromagnetic pulse valves and the vacuum cleaner fan. In automatic mode, based on the set blowing time (adjustable from 0-60s) and intermittent time (adjustable from 0-1200s), the PLC sequentially controls the four electromagnetic pulse valves to open and close in sequence, achieving relay blowing from the blowing points and gradually conveying the fallen hemp to the suction port of the vacuum duct. For example, the electromagnetic pulse valve closest to the suction port of the vacuum duct is controlled to activate first, and then the electromagnetic pulse valves of other blowing points are controlled in sequence, forming an orderly blowing cycle.

[0045] Meanwhile, the PLC can also calculate and monitor the amount of hemp falling on site in real time based on data such as the operating load of the vacuum cleaner fan. By monitoring parameters such as the current and voltage of the vacuum cleaner fan and combining them with a pre-set algorithm, the amount of hemp falling can be calculated and displayed on the operation screen. This allows operators to understand the equipment's operating status and hemp falling situation, enabling them to adjust equipment operating parameters or perform maintenance in a timely manner.

[0046] In manual mode, operators can select individual solenoid valves to activate via the control screen to handle specific impact points, facilitating operation when encountering malfunctions or needing to inspect a particular blow point individually. Upon receiving a manual operation command, the PLC controls the corresponding solenoid pulse valve to achieve precise control of each blow point.

[0047] The impurity pulse cleaning device features automatic blowing cleaning and simple touchscreen operation control.

[0048] (a) Press the start button on the electrical control box to power on the device;

[0049] (ii) Log in on the touchscreen to obtain operating permissions.

[0050] (III) First, start the vacuum cleaner fan, and then turn the four solenoid valves on and off in sequence. The solenoid valve closest to the suction port of the vacuum pipe will be activated first. The activation time of each solenoid valve is adjustable from 0 to 60 seconds (set: 3 seconds). The whole system operates in a cycle.

[0051] The new combing machine impurity pulse cleaning device is easy to operate, meets the different needs of each impurity point, reduces the impact on the factory, and has been tested and can meet the expected requirements.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
