Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a reciprocating cotton plucking machine and a control method thereof. Background Art

[0002] At present, the reciprocating plucker is a common raw material processing equipment in the spinning production process. It is mainly used to grab the cotton bales in the raw material area and transport them to the subsequent processing steps. The moisture content of the raw material has an important influence on the production quality and the stability of the subsequent process. Too low moisture content will lead to fiber breakage and static electricity accumulation, affecting the uniform transportation and mixing of cotton fibers, and thus affecting the yarn quality.

[0003] In the prior art, in order to increase the moisture content of raw materials, air conditioning humidification or spray humidification is usually used. Air conditioning humidification mainly relies on adjusting the ambient humidity to increase the moisture content of the raw materials, but this method has high investment costs, high operating energy consumption, and it is difficult for humidity to penetrate evenly into the interior of the raw materials, resulting in limited humidification effects. Spray humidification is to allow the raw materials to absorb moisture by spraying water mist in the air, but this method has certain limitations. On the one hand, it is difficult for the spray device to adjust the spraying amount according to the operating status of the equipment, which can easily lead to local excessive humidification, causing the moisture content of some cotton layers to be too high, affecting production quality; on the other hand, water mist in the air can easily enter the interior of the equipment, which may cause electrical components to become damp and damaged, affecting the normal operation and service life of the equipment.

[0004] Therefore, how to design a reciprocating cotton plucking machine that can avoid local over-humidification and water mist entering the interior of the equipment has become a technical problem that needs to be solved urgently by technical personnel in this field.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0040] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] This embodiment provides a bale opener to optimize the humidification method in the blow-carding unit production line, reduce the operating cost, and improve the uniformity of the moisture content of the raw materials.

[0042] Currently, in the blow-carding unit production line, in order to adjust the humidity of the production environment, an air-conditioning humidification system is usually adopted. Taking a typical blow-carding unit production line as an example, usually two air-conditioning rooms are required, which include six air supply fans and two water pumps. The equipment investment is large and the operating cost is high. However, this method mainly adjusts the overall environmental humidity, and the effect of improving the actual moisture content of the raw materials is limited. Especially in winter in Northeast China, the indoor humidity is low, and the moisture content of cotton fibers is difficult to reach the ideal level, which affects the stability of subsequent processes. At the same time, the top of the workshop may have condensed water droplets due to high humidity, which in turn affects the production environment and equipment operation.

[0043] Existing atomization devices mainly adopt wall-mounted centrifugal atomizers and air spray atomizers, but these methods have many deficiencies. On the one hand, such devices cannot be linked with the bale plucker, and the humidification process cannot be adjusted in real time according to the operating state of the host device, resulting in excessive humidification in local areas, causing the raw materials to get damp and entangled, and affecting production stability. On the other hand, the air spray device cannot avoid the host device, and the water mist is likely to enter the interior of the device, especially the electrical components, posing a risk of short circuit and affecting the safety of the device.

[0044] As Figures 1 to 2 shown, in the embodiment of the present invention, a reciprocating bale plucker is introduced to solve the above technical problems.

[0045] In this embodiment, the reciprocating bale plucker includes a guide rail and a main frame that can reciprocate along the guide rail. A bale plucking mechanism is provided on the main frame that can reciprocate in the vertical direction; the main frame is a portal frame, the bale plucking mechanism is installed on the portal frame, the guide rail is a linear horizontal guide rail arranged on the ground, and the bottom of the portal frame cooperates with the horizontal guide rail on the ground to realize the movement of the portal frame along the horizontal guide rail, thereby guiding the bale plucking mechanism to move horizontally with the portal frame to ensure that the bale plucking mechanism performs bale grabbing operations at different positions.

[0046] In this embodiment, the portal frame serves as the main body structure of the entire bale plucker. An atomization device 1 is provided on the portal frame. The spraying direction of the atomization device 1 is away from the bale plucking mechanism and the spraying direction is adjustable. The atomization device 1 is used to humidify the raw materials during the bale plucking process, specifically to convert the liquid into tiny droplets to achieve uniform spraying or humidification, etc., so as to optimize the raw material humidification effect, reduce static electricity accumulation, and improve production stability.

[0047] In this embodiment, the portal frame includes a horizontal support beam 2 at its top and two vertical support beams respectively connected to both ends of the horizontal support beam 2. The atomization device 1 is installed on the horizontal support beam 2, and the included angle between the spraying direction of the atomization device 1 and the length direction of the horizontal support beam 2 is an acute angle. Since both the portal frame and the bale plucking mechanism are part of the host device, the problem of damage to the electrical components of the host device caused by water mist entering the interior of the portal frame and the bale plucking mechanism can be avoided.

[0048] Specifically, in this embodiment, there are two horizontal support beams 2, and the two horizontal support beams 2 are arranged at intervals in the horizontal direction. During the bale plucking operation, the cotton conveying pipe connected to the bale plucking mechanism is located in the interval area between the two horizontal support beams 2 to ensure that the movement of the cotton conveying pipe is not interfered by the horizontal support beam 2.

[0049] More specifically, in this embodiment, there are two atomizing devices 1, and the two atomizing devices 1 are located on both sides of the moving track of the gantry frame. Specifically, the two atomizing devices 1 are respectively installed on two transverse support beams 2, and the two atomizing devices 1 are arranged opposite or staggered in the length direction of the transverse support beam 2. At the same time, the relative positions of the two atomizing devices 1 can adjust the atomization range according to different atomization requirements, so that the water mist can act on the cotton flow conveyed by the cotton conveying pipe evenly, further improving the humidifying effect, reducing the static electricity accumulation, and optimizing the stability of the subsequent process.

[0050] Preferably, the two atomizing devices 1 are arranged opposite to each other along the moving track of the gantry frame.

[0051] In a possible embodiment, the atomizing device 1 is installed on any vertical support beam of the gantry frame; or, there are at least two atomizing devices 1, and the at least two atomizing devices 1 are respectively arranged on two opposite vertical support beams of the gantry frame, and are on the same side or different sides along the moving track direction of the gantry frame, and the spraying end of the atomizing device 1 is inclined downward towards the raw material area.

[0052] In this embodiment, the cotton grabbing mechanism is movably installed on the gantry frame, and vertical guide rails are provided on the opposite inner sides of the two vertical support beams of the gantry frame; both sides of the cotton grabbing mechanism are installed on the gantry frame through the vertical guide rails and move in the vertical direction along the vertical guide rails.

[0053] More specifically, in this embodiment, rollers are provided at the bottom of the gantry frame to assist the gantry frame in moving along the horizontal guide rail.

[0054] In another possible embodiment, the horizontal guide rail is a circular guide rail, and the gantry frame moves in a circular shape on the circular guide rail.

[0055] In this embodiment, a detachable mounting part is provided on the transverse support beam 2, and the atomizing device 1 is detachably installed on the transverse support beam 2 of the gantry frame through the mounting part, so that the atomizing device 1 can be stably fixed and at the same time has the characteristics of convenient disassembly and maintenance.

[0056] Specifically, in this embodiment, the mounting part includes a three-dimensional frame, and the three-dimensional frame includes a first frame body 31 and a second frame body 32 that are parallel to each other, and columns 33 connecting the first frame body 31 and the second frame body 32.

[0057] More specifically, the first housing 31 is a first rectangular housing, and the second housing 32 is a second rectangular housing. The first rectangular housing and the second rectangular housing are arranged horizontally. Four columns 33 perpendicular to the first rectangular housing are connected to the bottoms of the four corners of the first rectangular housing. The bottoms of two adjacent columns 33 are connected to the upper ends of two adjacent corners of the second rectangular housing. The atomizing device 1 is placed on the second rectangular housing. The three-dimensional frame formed by the first rectangular housing and the four columns 33 connected to its bottom is snap-fitted onto the horizontal support beam 2 from top to bottom. That is, the atomizing device 1 is suspended outside the horizontal support beam 2 by being placed on the second rectangular housing to ensure the stability of the atomizing device 1 during the operation of the bale opener. Further, the distance between two adjacent columns 33 is adapted to the width of the horizontal support beam 2 of the portal frame to ensure that the three-dimensional frame can be stably snap-fitted onto the horizontal support beam 2.

[0058] In another specific embodiment, the mounting portion includes a U-shaped frame with its opening facing downwards, serving as a support hook to enable the atomizing device 1 to be suspended and fixed at the mounting point of the host device, that is, the atomizing device 1 is suspended on the portal frame. Further, limiting structures are provided at both ends of the U-shaped frame to prevent the atomizing device 1 from shaking or falling off during operation and ensure the stability of the installation.

[0059] In some more specific embodiments, threaded holes are provided on each column 33 for fixing to the horizontal support beam 2 to prevent loosening during operation. Specifically, a plurality of threaded holes arranged at intervals in the vertical direction are provided on each column 33. Further, two internal threaded holes penetrating the column 33 are provided on each column 33. In this way, the fixing height can be adjusted according to the installation requirements and the adaptability in different operating environments can be ensured. Through bolts or other fasteners, the atomizing device 1 can be firmly fixed to the horizontal support beam 2 in both the horizontal and vertical directions, avoiding loosening or displacement of the installation components due to equipment vibration or external interference, and thus avoiding affecting the efficiency.

[0060] Further, the installation method of this embodiment is not limited to the above scheme, and the fixing of the atomizing device 1 can also be achieved through other installation methods, such as using a clamping mechanism, a sliding locking mechanism, or a magnetic attraction fixing method, etc., to meet different usage scenarios.

[0061] In this embodiment, the water storage tank 11 of the atomization device 1 is arranged on the second housing 32 and is equipped with a submersible pump and a float switch; a fan bracket 14 is provided between the fan of the atomization device 1 and the water storage tank 11, and the fan is rotatably connected to the fan bracket 14; a regulating valve is provided on the water pipe connecting the atomization disc 12 of the atomization device 1 and the water storage tank 11; when water flows into the atomization disc 12 rotating at high speed, it is thrown out under the action of high-speed rotation to form tiny water mist, thereby realizing atomization humidification, and is used to control the spraying direction and coverage range of the water mist to ensure that the atomized water mist can act on the surface of the raw material evenly. The fan is used for secondary diffusion of the atomized water mist. In order to enhance the diffusion effect of the water mist and make the water mist more evenly distributed in the raw material area, avoiding local over-humidification or water mist accumulation.

[0062] In this embodiment, the water storage tank 11 and the air duct 13 of the fan are rotatably connected through the fan bracket 14, which is used to realize adjustable wind speed and wind direction of the fan to adapt to different working conditions and optimize the humidification effect.

[0063] Specifically, the fan bracket 14 includes a first connection part and a second connection part. The first connection part is an arc-shaped structure. The lower end of the first connection part is connected to the water storage tank 11, and the upper end of the first connection part is connected to the air duct 13 of the fan through the second connection part. The fan is rotatably connected to the arc-shaped structure through the second connection part, realizing adjustable fan orientation and enabling the atomized spray to be distributed within different height ranges.

[0064] In a more specific embodiment, when the cotton layer thickness in the raw material area is relatively high, the air duct 13 rotates downward to adjust the spraying angle, making the water mist act more directly on the surface of the cotton layer, improving the atomization efficiency and reducing the diffusion loss of the water mist in the air; when the cotton layer is thinner, the air duct 13 rotates upward to adjust the spraying angle, making the spray coverage range wider, ensuring uniform humidification of the cotton layer and avoiding over-humidification in local areas at the same time.

[0065] Specifically, in this embodiment, the second connection part is provided with a guiding structure and a limiting structure. The fan is rotatably connected to the fan bracket 14 through the guiding structure and the limiting structure; the guiding structure is an arc-shaped groove, and the limiting structure is a round hole. The round hole is used for fixed installation. The arc-shaped groove is used on the one hand to adjust the fan spraying angle, and on the other hand to cooperate with the round hole to realize the connection between the fan and the water storage tank 11.

[0066] Preferably, in this embodiment, an overflow tank is provided below the atomization disk 12 for collecting excess water flow to prevent water overflow in the atomization device 1; an overflow pipe is provided between the overflow tank and the water storage tank 11, and the overflow tank is arranged at the bottom of the atomization disk 12. Further, the lowest point of the overflow tank is connected to a PU hose through a plug-and-play quick connector as the overflow pipe, and the overflow pipe is directly inserted into the water storage tank 11 to return the excess water flow to the water storage tank 11, forming a circulating water supply system, reducing water resource waste and improving the operation efficiency of the equipment.

[0067] In another possible embodiment, the overflow tank is arranged at the top of the water storage tank 11.

[0068] As Figure 2 shown, in this embodiment, the atomization device 1 is configured with a water supply system to ensure stable water supply for the atomization device 1, optimize the humidification effect, and improve the reliability of equipment operation. The water supply system includes a water supply pipe, a switch valve, a three-way valve, a regulating valve, and a submersible pump, and each component is connected through a PU hose and a plug-and-play quick connector to achieve convenient disassembly and assembly and efficient water supply.

[0069] Specifically, in this embodiment, two atomization devices 1 are respectively connected to the water supply pipe. Along the internal water flow direction of the water supply pipe, a three-way valve and a switch valve are successively arranged, and the water supply pipe is connected to the two atomization devices 1 simultaneously through the three-way valve. Further, the three-way valve is used to balance the potential energy between the two water storage tanks 11, so that the water supply amounts of the two water storage tanks 11 are kept consistent, preventing uneven water supply caused by liquid level differences.

[0070] More specifically, in this embodiment, the water supply pipe is connected to the switch valve through a plug-and-play quick connector to facilitate quick disassembly and maintenance of the pipeline. A PU hose is used to connect between the switch valve and the three-way valve and is fixed through a plug-and-play quick connector to ensure the connection stability of the water supply pipe.

[0071] In another specific embodiment, the water supply pipe is connected to any one of the atomization devices 1 through a three-way valve, that is, controlling the water supply of a single water storage tank 11 to make the water supply system have higher flexibility.

[0072] Specifically, in this embodiment, in order to ensure the liquid level control of the water storage tank 11, the water storage tank 11 is configured with a float switch, or the liquid level can be controlled by cooperating the switch valve with a liquid level gauge. A PU hose is used to connect between the three-way valve and the float switch and is fixed through a plug-and-play quick connector to ensure the reliability of the water circuit, and at the same time facilitate maintenance and replacement.

[0073] More specifically, in this embodiment, a submersible pump is provided at the bottom of the water storage tank 11 to provide a stable water supply pressure and ensure that the atomizing device 1 obtains a stable water flow. Three holes are provided at the top of the box body of the water storage tank 11 for the entry of equipment, connection of the water supply pipe, and connection of the overflow pipe. Further, all three holes are equipped with threaded structure plugging covers to ensure the sealing performance and structural stability.

[0074] Specifically, in this embodiment, the water outlet end of the submersible pump is connected to the regulating valve through a PU hose and fixed with a plug-in quick connector. Further, the regulating valve can be an electric regulating valve or a manual regulating valve to automatically or manually adjust the water supply volume according to the operating conditions of the equipment, ensuring that the atomizing device 1 can achieve the optimal atomization volume requirement.

[0075] More specifically, in this embodiment, the downstream of the regulating valve is connected to the centrifugal atomizing disk 12 through a PU hose. The atomizing disk 12 is provided with kinetic energy by a single-phase or three-phase asynchronous motor, so that the water flow forms atomized particles through the high-speed rotating atomizing disk 12, realizing efficient humidification.

[0076] In this embodiment, the atomizing device 1 is electrically connected to the control system to achieve precise adjustment and intelligent control during the atomization process of the atomizing device 1. The control system is mainly composed of a power distribution unit, a logic control unit (PLC), a sensor module, a drive execution unit, etc., and can be linked with the motion state of the host device in real time to optimize the atomization effect;

[0077] Specifically, in this embodiment, the drive execution unit includes an inverter, a regulating valve, and a drive motor connected to the atomizing device 1. According to the different specifications of the drive motor of the atomizing device 1, a 2P, 3P, or 4P air switch can be selected as the main circuit breaker to ensure the safety of the circuit. Further, the sub-switches of the main circuit breaker include an atomizer power circuit breaker and a control circuit circuit breaker, which respectively control the power supply of the atomizing device 1 and the stable operation of the control circuit, ensuring the reliability and safety of the system.

[0078] In this embodiment, the control power supply is provided by a 24V rectified power supply to ensure the safety and stability of the low-voltage control circuit. The logic control is completed by a PLC (programmable logic controller). The PLC receives sensing signals through the input / output module and controls the working state of the atomizing device 1. Among them, the PLC input end is connected to a rotary encoder, a roller sensor, a start button, a stop button, and an origin signal sensor, which is used to monitor the motion state and position information of the host device, ensuring that the atomization control can respond to the operation of the bale opener in real time; further, the origin signal sensor can be a proximity switch, a photoelectric switch, or a travel switch.

[0079] In terms of output control, the PLC provides two atomizer start signals through digital outputs to trigger the frequency converter start signals of the corresponding atomizers, and provides a program start signal to control the on / off state of the operation indicator light. In addition, the PLC also provides two frequency converter frequency signals and two regulating valve opening signals through analog outputs to control the air volume, atomization amount, and water supply amount of the atomization device 1 respectively, ensuring that the atomization process is accurately matched with the operating state of the host equipment.

[0080] In this embodiment, a rotary encoder is used in conjunction with a runner of a standard size to provide continuous position signals for monitoring the motion state of the host equipment. The PLC collects the current position data at a period of 100 ms through a custom interrupt program and compares it with the position information at the previous moment in real time, so as to judge the operating state of the host equipment. Based on this judgment, the PLC can complete the output of the start / stop command of the atomization device 1 within 100 ms, realizing a fast response after the state change of the host equipment.

[0081] Through the calculation results, the PLC can accurately obtain the motion direction, motion state, and location of the host equipment, thus realizing a variety of intelligent responses, including: controlling the start / stop of the atomizers in the corresponding direction or the opposite direction according to the motion direction to ensure that the atomization process matches the motion of the bale opener; when the host equipment starts or stops, the atomization system can respond synchronously according to the motion state to avoid unnecessary atomization start or stop, reducing energy consumption and water resource waste; also, dynamically adjusting the atomization parameters according to the location of the host equipment to match the humidification requirements of different working areas and improve the humidification uniformity.

[0082] In this embodiment, the air volume and atomization amount of the atomizer are controlled by a frequency converter, and the water supply amount is controlled by a regulating valve to achieve precise adjustment of the atomization parameters. The frequency converter can adjust the fan speed to control the diffusion range and concentration of the atomized water mist, while the regulating valve directly affects the atomization effect by controlling the water supply amount, making the humidification process more precisely controllable.

[0083] In this embodiment, the distribution box is connected to the external power supply line and signal line in the form of aviation plugs, which is convenient for the disassembly and movement of the distribution box, and at the same time ensures convenient installation, improving the reliability and durability of the connection.

[0084] In this embodiment, a control method for a reciprocating bale opener is also provided, which is used to dynamically adjust the operating state of the atomization device 1 during the bale opening operation to optimize the humidification effect, improve the moisture uniformity of the raw materials, and reduce the influence of static electricity on the bale opening process.

[0085] In a specific embodiment, when the gantry frame moves in the first direction, the atomizing device 1 located on the main frame at the rear side relative to the first direction is turned on to spray and humidify the raw material area, so as to increase the moisture content of the cotton layer to be grabbed, prevent the cotton fibers from being too dry, and improve the grabbing efficiency. When the main frame moves in the direction opposite to the first direction, the atomizing device 1 located on the main frame at the rear side relative to this direction is turned on.

[0086] In another specific embodiment, to meet the humidification requirements of different raw material areas, the two atomizing devices 1 can be turned on simultaneously under specific working conditions, that is, when the main frame performs cotton grabbing operations in a specific humidification area, the two atomizing devices 1 work synchronously to improve the humidification uniformity. Among them, the atomizing device 1 located on the main frame at the rear side relative to the first direction is used to pre-humidify the cotton layer in the grabbing area before the cotton grabbing mechanism grabs the cotton, so as to increase the moisture content of the cotton to an appropriate level and prevent flying lint and static electricity accumulation; the atomizing device 1 located on the main frame at the front side relative to the first direction is used to continue spraying on the grabbed area after the cotton grabbing mechanism has completed the grabbing, so as to keep the ungripped cotton moist so that it is still in a good humidity state when the next cycle of grabbing continues.

[0087] In this embodiment, the operation of the atomizing device 1 is controlled by preset parameters to ensure that the moisture content of different raw material areas reaches the set requirements. The preset parameters are adapted to different raw material areas, that is, for different types of raw materials or different humidification requirements, the system can call different atomizing parameters for precise atomization.

[0088] Specifically, in this embodiment, the preset parameters at least include the atomizing amount and the humidification area. The atomizing amount adjusts the water supply and the working power of the atomizing device 1 according to the moisture content requirements of the raw material to ensure uniform humidification and prevent over-humidification or under-humidification. The humidification area controls the opening position and coverage range of the atomizing device 1 so that the spray acts on the target area without affecting the moving parts of the cotton grabbing mechanism or the main frame.

[0089] In this embodiment, the preset parameters can be dynamically adjusted by the control system according to the environmental monitoring data. The control system can receive the data from the humidity sensor or the temperature sensor and automatically adjust the atomizing amount and the humidification area according to the current humidity condition of the raw material area to optimize the humidification effect. For example, when the environmental humidity is high, the system can reduce the atomizing amount to reduce unnecessary humidification to maintain an appropriate moisture content of the raw material.

[0090] In this embodiment, the control system, through a logic control unit (such as a PLC), combines the moving state of the main frame with preset parameters and performs the following steps: First, when the main frame moves, the system obtains the current moving direction and selectively activates the atomizing device 1 or simultaneously activates both atomizing devices 1 according to the direction. Second, the control system queries the preset parameters, determines the humidification requirement of the current raw material area, and calculates the appropriate atomizing amount and spray coverage range. Then, the system sends a control signal to the drive execution unit to adjust the water supply amount, fan speed, and spray pressure of the atomizing device 1 to match the requirements of the raw material area. Finally, feedback control is performed based on the sensor data. If it is detected that the humidity in the humidification area reaches the set value, the atomizing amount is adjusted or the atomizing device 1 is turned off to prevent over-humidification.

[0091] Furthermore, in this embodiment, the control system automatically adjusts the angle of the air duct 13 according to the preset parameters or the feedback signal of the humidity sensor to meet the humidification requirements under different working conditions. For example, when it is detected that the humidity in the raw material area is lower than the set threshold, the control system can adjust the angle of the air duct 13 to increase the spray coverage range and make the humidification more uniform; when the humidity reaches the set value, the control system can adjust the air duct 13 to a smaller spraying angle or stop spraying to avoid over-humidification.

[0092] In another possible embodiment, the rotation angle of the air duct 13 of the atomizing device 1 is manual. In the manual adjustment mode, the operator can make the air duct 13 stay at the target angle position according to the cotton layer thickness and water content requirement in the raw material area.

[0093] In this embodiment, through the atomization control based on the moving state of the main frame, the water mist is always sprayed towards the raw material area without affecting the normal operation of the bale plucker mechanism. At the same time, by matching the preset parameters with the water content requirements of different raw material areas, the moisture content of each raw material area is ensured to be uniform, the humidification efficiency is improved, over-humidification or under-humidification of local areas is prevented, the degree of automation is enhanced, and manual intervention is reduced.

[0094] In this embodiment, the type of the bale plucker is not limited to the reciprocating bale plucker, and the specific model can be selected according to actual needs.
