Description

Technical Field

[0001] This invention relates to the field of new energy strip cleaning technology, and in particular to a fully automatic high-pressure strip cleaning machine. Background Technology

[0002] With the modernization of the new energy industry, the manufacturing process requirements for front-end products in the lithium battery industry are becoming increasingly stringent. As the cleaning process for lithium strip products is improved, the process requirements are becoming increasingly demanding, and conventional high-pressure cleaning equipment can no longer meet market demands. Looking at the common high-pressure water and ultrasonic cleaning machines on the market, they are generally composed of key parts such as control system, pressurization system, water supply and drainage system, ultrasonic system, spray system, and cleaning system. Their working principle is mainly to pressurize the mixture of cleaning agent and water to a certain pressure through the pressurization system, and then spray it onto the surface of the object from a spray device with many spray holes.

[0003] Currently, most cleaning machines on the market have complex structures and lack complete cleaning systems, resulting in low cleaning efficiency, poor cleaning quality, large tension fluctuations, and inability to control tension to meet market demands. They also suffer from poor strip winding, misalignment, and low winding efficiency. Summary of the Invention

[0004] This invention provides a fully automatic high-pressure strip cleaning machine, which aims to solve the problems of low cleaning efficiency, poor cleaning quality, and difficulty in rewinding strips, resulting in poor rewinding effect and low rewinding efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

There is a gap between the opposing air knife blowing mechanisms for the strip to pass through. The upper and lower adjacent conveyor rollers are arranged in a transversely staggered manner. The high-pressure spray device corresponds to each of the conveyor rollers. The high-pressure spray device is respectively located above the corresponding upper conveyor roller and below the adjacent lower conveyor roller. The high-pressure rough washing tank is equipped with a water immersion tank. At least one lower conveyor roller is located in the water immersion tank.

The pressure sensor and the high-pressure pump are electrically connected to the frequency converter. Multiple fan-shaped nozzles are arranged at the end of the spraying pipe away from the high-pressure pump, and the spraying direction of the fan-shaped nozzles is opposite to the conveying direction of the strip.

[0012] Furthermore, the air knife blowing mechanism includes a fan, an air duct, a regulating valve, and an air knife. The air outlet of the fan is connected to the air inlet of the air duct, the air outlet of the air duct is connected to the air knife, and a regulating valve is provided at the end of the air duct near the air knife.

[0013] Furthermore, the extrusion anti-water-crossing mechanism includes a square extrusion support, an upper extrusion roller, and a lower extrusion roller.

The piston rod of the cylinder slides through the piston rod hole and is fixedly connected to the upper extrusion roller support. The upper extrusion roller support has two guide shaft holes, which are arranged opposite to each other on both sides of the cylinder. A linear bearing is disposed in each guide shaft hole, and a guide shaft is slidably disposed within the linear bearing. The guide shaft passes through the corresponding guide shaft hole and is fixedly connected to the upper extrusion roller support.

[0014] Furthermore, the high-pressure rough washing tank, low-pressure rough washing tank, high-pressure cleaning tank, low-pressure cleaning tank, and pure water cleaning tank are all equipped with overflow outlets.

[0016] The beneficial effects of this invention are as follows: This fully automatic high-pressure strip cleaning machine comprises a first correction mechanism that corrects the angle at which the strip is released from the unwinding mechanism, preventing the strip from deviating; a first tension control mechanism that maintains stable tension in the strip, preventing wrinkling or breakage; and the first correction mechanism and the first tension control mechanism that enable smooth unwinding. A second correction mechanism adjusts and corrects the angle of the strip, straightening any deviations and facilitating alignment and winding; the second tension control mechanism further stabilizes the tension in the strip, further preventing wrinkling or breakage. The first correction mechanism, the first tension control mechanism, the second correction mechanism, and the second tension control mechanism work together to ensure smooth strip winding, significantly improving winding effect and efficiency. The strip is unwound by the unwinding device and then enters a high-pressure anti-water-crossing cleaning device for efficient and high-quality cleaning. After cleaning, the strip enters a hot air drying device for drying, and the winding device winds it up for later use. The automatic cleaning process—unwinding, cleaning, drying, and winding—is achieved through a continuous process, improving cleaning efficiency and quality, thereby enhancing factory production efficiency and quality.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a fully automatic strip high-pressure cleaning machine of the present invention includes a frame 7. The frame 7 is provided with an unwinding device 1, a high-pressure anti-water washing device 2, a hot air drying device 4 and a winding device 5 arranged sequentially along the feeding direction of the strip 6. The unwinding device 1 includes an unwinding mechanism 103, a first correction mechanism 102 and a first tension control mechanism 101. The winding device 5 includes a second correction mechanism 501, a second tension control mechanism 503 and a winding mechanism 502.

[0027] Based on the above structure, the fully automatic strip high-pressure washer features a first correction mechanism 102 that corrects the angle at which the strip 6 is released from the unwinding mechanism, preventing the strip 6 from deviating. A first tension control mechanism 101 maintains stable tension in the strip 6, preventing wrinkling or breakage. The first correction mechanism 102 and the first tension control mechanism 101 ensure smooth unwinding. A second correction mechanism 501 adjusts and corrects the angle of the strip 6, straightening any deviations and facilitating alignment during winding. A second tension control mechanism 503 further stabilizes the tension in the strip 6, further preventing wrinkling or breakage. The first correction mechanism 102, the first tension control mechanism 101, the second correction mechanism 501, and the second tension control mechanism 503 work together to ensure smooth winding of the strip 6, significantly improving winding effect and efficiency. Strip 6 is unwound by unwinding device 1 and enters high-pressure anti-water-crossing cleaning device 2 for efficient and high-quality cleaning. After cleaning, strip 6 enters hot air drying device 4 for drying and is then wound up by winding device 5 for later use. The unwinding-cleaning-drying-winding process achieves automatic cleaning with good process continuity, stable production flow, and high working efficiency. It is suitable for mass production, greatly improving cleaning efficiency and quality, thereby improving factory production efficiency and quality while reducing production costs.

[0028] Preferably, a correction device 3 is provided between the high-pressure anti-water-crossing cleaning device 2 and the hot air drying device 4, and the correction device 3 is provided with a third correction mechanism 301.

[0029] The third correction mechanism 301 corrects the angle of the strip 6, straightens the misaligned strip 6, and allows the cleaned strip 6 to smoothly enter the hot air drying device 4.

[0030] The first correction mechanism 102, the second correction mechanism 501, and the third correction mechanism 301 are the same correction mechanism. Each correction mechanism includes a correction support 1022, a driver 1024, a correction guide wheel 1023, a correction guide roller 1021, an L-shaped correction guide roller mounting plate 1027, a correction sensor 1026, and a correction controller 1025. The correction guide roller mounting plate 1027 is rotatably mounted on the correction support 1022, and the driver 1024 is mounted on the correction support 1022. On 022, the driver 1024 is located below the correction roller mounting plate 1027. The lower end of the correction guide wheel 1023 is rotatably mounted on the driver 1024. The upper end of the correction guide wheel 1023 is fixedly connected to the bottom of the correction roller mounting plate 1027. The two correction rollers 1021 are rotatably mounted laterally on the inner side wall of the correction roller mounting plate 1027. The correction sensor 1026, the driver 1024, and the correction controller 1025 are electrically connected to each other.

[0031] The correction sensor 1026 emits an ultrasonic signal to detect the running status of the strip 6 and sends the detected signal to the correction controller 1025. Based on its judgment, the correction controller 1025 instructs the driver 1024 to operate. The driver 1024 controls the correction guide roller 1023 to adjust the angle of the correction roller 1021, ultimately correcting the misaligned strip 6. If the strip 6 is being conveyed normally without deviation, the correction sensor 1026 sends a normal conveyance signal to the correction controller 1025. After judgment, the correction controller 1025 does not send a start command to the driver 1024, and the strip 6 is conveyed normally. If the strip 6 is misaligned, after passing the correction sensor 1026, the correction sensor 1026 sends a misalignment signal to the correction controller 1025. After judgment, the correction controller 1025 sends a start command and correction direction and angle to the driver 1024. The driver 1024 then starts, causing the correction guide roller 1023 to rotate by the specified angle in the correction direction, completing the correction of the strip 6. The alignment roller mounting plate 1027 is rotatably mounted on the alignment support 1022 via a rotating shaft. The upper end of the rotating shaft is fixedly connected to the alignment roller mounting plate 1027, and the lower end of the rotating shaft is rotatably mounted on the alignment support 1022. The driver 1024 includes a rotary motor, and the lower end of the alignment guide wheel 1023 is fixedly connected to the rotating shaft of the rotary motor. There are two alignment guide wheels 1023, and the two alignment guide wheels 1023 rotate synchronously.

[0032] The first tension control mechanism 101 and the second tension control mechanism 503 are the same tension control mechanism. The tension control mechanism includes a U-shaped tension control sensor mounting base 1011, a tension control sensor 1013, and a guide roller 1012. The guide roller 1012 is rotatably disposed between the two side walls of the tension control sensor mounting base 1011, and the tension control sensor 1013 is provided at both ends of the guide roller 1012.

[0033] The strip 6 passes through the guide roller 1012, generating tension on the guide roller 1012. The tension control sensor 1013 detects the tension data, and the controller judges the data and controls the unwinding speed of the unwinding mechanism 103. The unwinding mechanism 103 includes a rotary wheel and an unwinding motor. The unwinding motor is electrically connected to the controller, and the controller controls the output power of the unwinding motor to control the unwinding speed of the unwinding mechanism 103.

[0034] Specifically, the high-pressure anti-cross-water cleaning device 2 includes a cleaning tank with a top cover 206. The cleaning tank is divided by a partition 208 into a high-pressure coarse washing tank 203, a low-pressure coarse washing tank 205, a high-pressure cleaning tank 207, a low-pressure cleaning tank 209, and a pure water cleaning tank 2011. Multiple conveyor rollers 20101 and multiple high-pressure spray devices 202 are spaced apart in each of the high-pressure coarse washing tank 203, the low-pressure coarse washing tank 205, the high-pressure cleaning tank 207, the low-pressure cleaning tank 209, and the pure water cleaning tank 2011. The high-pressure spray devices 202 are arranged in two vertically distributed rows, and the conveyor rollers 20101 are arranged in two vertically distributed rows, with the two rows of conveyor rollers located between the two rows of high-pressure spray devices. The low-pressure coarse washing... Each of the tanks 205, 207, 209, and 2011 is equipped with a corresponding air knife blowing mechanism 204. The corresponding air knife blowing mechanisms 204 have a gap for the strip to pass through. The upper and lower adjacent conveyor rollers 20101 are arranged in a transversely staggered manner. The high-pressure spray device 202 corresponds to each of the conveyor rollers 20101. The high-pressure spray device 202 is respectively located above the corresponding upper conveyor roller 20101 and below the adjacent lower conveyor roller 20101. The high-pressure coarse washing tank 203 is equipped with a water immersion tank 2013. At least one lower conveyor roller 20101 is located in the water immersion tank 2013. The ends of the low-pressure washing tank and the pure water washing tank 2011 are equipped with a squeezing anti-water crossing mechanism 2010.

[0035] The partition 208 divides the cleaning tank into five sequentially arranged cleaning tanks: a high-pressure rough washing tank 203, a low-pressure rough washing tank 205, a high-pressure cleaning tank 207, a low-pressure cleaning tank 209, and a pure water cleaning tank 2011. These five tanks, each with a different cleaning process, effectively prevent cross-flow and contamination of the cleaning fluid within each tank, effectively avoiding water seepage during the strip cleaning process and preventing large-scale water pollution. This allows the water in each cleaning tank to be reused, thus significantly saving water resources. The squeezing anti-cross-flow mechanism 2010 located at the end of the low-pressure cleaning tank 209 and the pure water cleaning tank 2011 effectively removes residual wastewater from the high-pressure rough washing tank 203, low-pressure rough washing tank 205, and high-pressure cleaning tank 207, reducing the contamination of the low-pressure cleaning tank 209 and the pure water cleaning tank 2011 by residual wastewater, preventing water seepage caused by residual wastewater, further enhancing the anti-cross-flow capability of this high-pressure anti-cross-flow cleaning device, and further saving water resources. Air knife blowing mechanisms 204 are arranged opposite each other in the low-pressure rough washing tank 205, high-pressure washing tank 207, low-pressure washing tank 209, and pure water washing tank 2011. The strip 6 passes through the gap between two oppositely arranged air knife blowing mechanisms 204, effectively blowing away the cleaning fluid and stains carried out from the previous washing tank. This reduces the contamination of the cleaning fluid and stains in the subsequent washing tank, avoids water seepage caused by stains, further improves the water seepage prevention capability of this high-pressure anti-water seepage cleaning device, and further saves water resources. Blowing away the cleaning fluid and stains carried out from the previous washing tank improves cleaning efficiency and cleaning quality. For example, the air knife blowing mechanism 204 in the low-pressure rough washing tank 205 (the subsequent washing tank)... Air knife blowing mechanism 204 blows away the cleaning fluid and stains carried out from the high-pressure rough cleaning tank 203 (the previous cleaning tank) on the strip 6. Air knife blowing mechanism 204 in high-pressure cleaning tank 207 (the next cleaning tank) blows away the cleaning fluid and stains carried out from the low-pressure rough cleaning tank 205 (the previous cleaning tank) on the strip 6. Air knife blowing mechanism 204 in low-pressure cleaning tank 209 (the next cleaning tank) blows away the cleaning fluid and stains carried out from the high-pressure cleaning tank 207 (the previous cleaning tank) on the strip 6. Air knife blowing mechanism 204 in pure water cleaning tank 2011 (the next cleaning tank) blows away the cleaning fluid and stains carried out from the low-pressure cleaning tank 209 (the previous cleaning tank) on the strip 6. The air knife blowing mechanism 204, which is set opposite to each other, blows air onto the upper and lower surfaces of the strip 6 simultaneously, which can effectively remove residual stains on the strip 6.During the cleaning process of strip 6, strip 6 first passes through a high-pressure coarse washing tank 203 to remove most of the dirt; then it passes through a low-pressure coarse washing tank 205 to remove residual dirt; next, it passes through a high-pressure cleaning tank 207 to remove the cleaning fluid and residual dirt from the coarse washing tank; then it passes through a low-pressure cleaning tank 209 to remove residual cleaning fluid and residual dirt; finally, it passes through a pure water cleaning tank 2011 to remove a small amount of residual cleaning fluid and residual dirt again, resulting in clean strip 6. After five consecutive cleaning cycles, the clean strip 6 required by the industry is obtained, eliminating the need for repeated cleaning, thus effectively improving cleaning efficiency and quality. The conveyor roller 201 is located between two rows of high-pressure spray device groups. The strip 6 is moved by the rotation of the conveyor roller 201. The high-pressure spray device 202 can spray and clean the upper and lower surfaces of the strip, improving cleaning efficiency and quality. The high-pressure coarse washing tank 203 is equipped with an immersion tank 2013, and at least one conveyor roller 20101 is located in the immersion tank 2013. When the strip 6 passes through this conveyor roller 20101, the soaking liquid in the immersion tank 2013 fully immerses the strip 6, improving the cleaning quality. In summary, this high-pressure anti-cross-water cleaning device effectively prevents cross-water and improves cleaning efficiency and cleaning quality, thereby improving the cleaning efficiency and cleaning quality of this fully automatic strip high-pressure cleaning machine.

[0036] Specifically, the high-pressure spraying device 202 includes a high-pressure pump, a pneumatic valve, a pressure sensor, a frequency converter, a spraying pipe, and fan-shaped nozzles. The inlet of the high-pressure pump is connected to an external water supply pipe, and the outlet of the high-pressure pump is connected to the spraying pipe. A pneumatic valve and a pressure sensor are sequentially arranged along the water flow direction at the end of the spraying pipe near the high-pressure pump. The pressure sensor and the high-pressure pump are electrically connected to the frequency converter. Multiple fan-shaped nozzles are arranged at the end of the spraying pipe away from the high-pressure pump. The spraying direction of the fan-shaped nozzles is opposite to the conveying direction of the strip 6.

[0037] A pressure sensor collects the water pressure signal inside the spray pipe and transmits it to the frequency converter. The frequency converter adjusts the power of the high-pressure pump based on the water pressure, thereby adjusting the spray rate of the fan-shaped nozzles to meet the spraying requirements of different strips. If the water pressure in the spray pipe is too low, the power of the high-pressure pump is increased; if the water pressure is too high, the power of the high-pressure pump is decreased, which is very convenient. The pressure sensor and pneumatic valve are electrically connected to the controller. The pressure sensor collects the water pressure signal inside the spray pipe and transmits it to the controller. The controller instructs the pneumatic valve to control the flow rate of the liquid in the spray pipe. In this way, the pneumatic valve can further control the flow rate of the liquid in the spray pipe, thereby controlling the spray rate of the fan-shaped nozzles. If the water pressure in the spray pipe is too high, the controller instructs the pneumatic valve to reduce the flow rate; if the water pressure is too low, the controller instructs the pneumatic valve to increase the flow rate. The high-pressure pump, pressure sensor, frequency converter, and controller are powered by an external power source. Compared to cylindrical nozzles, fan-shaped nozzles offer advantages such as better jet density, greater spray diffusion range, and larger cleaning area, effectively improving spray cleaning efficiency. All fan-shaped nozzles are evenly distributed along the spray pipes. The spray direction of the fan-shaped nozzles is opposite to the conveying direction of strip 6, increasing the impact force between the water flow and the surface of strip 6. Reverse spraying allows for better cleaning of strip 6. At the same spray rate (with the same high-pressure pump power), reverse spraying is more effective and saves energy.

[0038] The pressure output of the fan-shaped nozzle is p, where 1MPa ≤ p ≤ 12MPa; the flow rate of the high-pressure pump is Q, where 120L / min ≤ Q; and the power of the high-pressure pump is P, where 20KW ≤ P. The pressure output of the fan-shaped nozzle, p, can be adjusted according to cleaning requirements, such as 1MPa, 2MPa, 3MPa, 5MPa, 8MPa, 12MPa, etc. The flow rate of the high-pressure pump, Q, can be adjusted according to cleaning requirements, such as 120L / min, 130L / min, 140L / min, etc. The power of the high-pressure pump, P, can be adjusted according to cleaning requirements, such as 20KW, 21KW, 22KW, 25KW, 30KW, etc.

[0039] Specifically, the air knife blowing mechanism 204 includes a fan, an air duct, a regulating valve, and an air knife. The air outlet of the fan is connected to the air inlet of the air duct, the air outlet of the air duct is connected to the air knife, and a regulating valve is provided at the end of the air duct near the air knife.

[0040] The air-blowing mechanism 204 of the air knife provides airflow via a fan or compressed air. Compressed air enters the air knife and is blown out at high speed through a thin sheet of air only 0.05 mm thick. Utilizing the Coanda effect and the air knife's unique geometry, this thin air curtain can blow 30-40 times more air than the ambient air, creating a thin, high-intensity, high-airflow impact curtain. Air knives are classified into two types based on their operating mode: standard air knives and super air knives. Standard air knives deflect their air curtain 90 degrees before blowing out, while super air knives blow their air curtain horizontally, creating a high-intensity impact airflow. They are used for water removal, air blowing, dust removal, cleaning, drying, and cooling, and feature high efficiency, low noise, and low air consumption. They are ideal for use in this high-pressure anti-water-crossing cleaning device, blowing away water brought in from the previous cleaning unit from the strip 6, further preventing water cross-contamination in the cleaning tank, and facilitating the drying of the strip 6 in preparation for the next process. The regulating valve can be installed on the duct near the air knife end or on the duct near the fan end, depending on the ease of adjustment.

[0041] The extrusion anti-water-crossing mechanism 2010 includes a square extrusion support 20107, an upper extrusion roller 20105, and a lower extrusion roller 20106. The lower extrusion roller 20106 is rotatably disposed within the extrusion support 20107. A U-shaped upper extrusion roller support 20104 is disposed within the extrusion support 20107, with the opening of the upper extrusion roller support 20104 facing the lower extrusion roller 20106. The upper extrusion roller 20105 is rotatably disposed within the upper extrusion roller support 20104. A gap for the strip 6 to pass through is provided between the upper extrusion roller 20105 and the lower extrusion roller 20106. The axis of the upper extrusion roller 20105 and the lower extrusion roller 20106 are aligned. The axes of rollers 20106 are parallel. A cylinder 20101 is provided on the top surface of the upper end of the extrusion support 20107. A piston rod hole is opened on the top surface of the upper end of the extrusion support 20107. The piston rod of the cylinder 20101 slides through the piston rod hole and is fixedly connected to the upper extrusion roller support 20104. The upper extrusion roller support 20104 has two guide shaft holes, which are arranged opposite to each other on both sides of the cylinder 20101. A linear bearing 20103 is provided in the guide shaft hole. A guide shaft 20102 is slidably arranged in the linear bearing 20103. The guide shaft 20102 passes through the corresponding guide shaft hole and is fixedly connected to the upper extrusion roller support 20104.

[0042] Strip 6 passes through the gap between the upper extrusion roller 20105 and the lower extrusion roller 20106. The piston rod of the working cylinder 20101 of cylinder 20101 presses down on the upper extrusion roller support 20104. The upper extrusion roller support 20104 drives the upper extrusion roller 20105 to move towards the lower extrusion roller 20106, so that the upper extrusion roller 20105 presses on the upper surface of strip 6. Strip 6 drives the upper extrusion roller 20105 and the lower extrusion roller 20106 to rotate, and the upper extrusion roller 20105 and the lower extrusion roller 20106 squeeze the strip 6. The residual moisture on the upper and lower surfaces of the strip 6 is squeezed out, which can accommodate strips 6 of different thicknesses. The outer diameter of the linear bearing 20103 is larger than the inner diameter of the guide shaft hole, so that the linear bearing 20103 covers the guide shaft hole. The guide shaft 20102 serves a guiding function, guiding the upper extrusion roller support 20104 and the upper extrusion roller 20105 to move up and down along the axis of the guide shaft 20102 towards the lower extrusion roller 20106. The guide shaft 20102, together with the piston rod of the cylinder 20101, acts as a limiting element and maintains the parallelism between the axes of the upper extrusion roller 20105 and the lower extrusion roller 20106. The two guide shafts 20102 provide better limiting and better maintain the parallelism between the axes of the upper extrusion roller 20105 and the lower extrusion roller 20106. The upper extrusion roller 20105 and the lower extrusion roller 20106 uniformly extrude the strip 6, better squeezing out residual moisture from the strip 6, while preventing deformation of the strip 6 that could lead to inconsistent thickness. Furthermore, the centers of the upper extrusion roller 20105 and the lower extrusion roller 20106 are collinear. The linear bearing 20103 can be a sleeve, and the guide shaft 20102 can be a guide rod, which is slidably disposed within the sleeve. Cylinder 20101 can be a motor, a jack, or an electric jack.

This counter-current cleaning method allows for the addition of clean water once, which is then reused multiple times, greatly saving water resources. Overflow outlets can be installed on the bottom side wall or bottom wall of the high-pressure coarse washing tank 203, low-pressure coarse washing tank 205, high-pressure cleaning tank 207, low-pressure cleaning tank 209 and pure water cleaning tank 2011 respectively.
