Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, specifically to an ultrasonic cleaning device for stamped material strips. Background Technology

[0002] Currently, stamped products need to be cleaned immediately after they are produced from the machine. If they are only cleaned after a certain quantity has been produced, it is a waste of time and inefficient.

[0003] An existing patent (publication number: CN207222481U) discloses an online ultrasonic automatic cleaning system for stamped parts, characterized in that: the system includes a feeding device, a punching mechanism, a cleaning tank, a drying chamber, and a receiving device; the feeding device is located at the front end of the punching mechanism, the output end of the punching mechanism is equipped with the cleaning tank and the drying chamber, and the receiving device is located at the output end of the drying chamber; an ultrasonic generator is installed in the cleaning fluid in the cleaning tank, which can generate a large number of high-pressure microbubbles in the cleaning fluid, creating high-pressure bombardment on the surface of the stamped parts, causing the dirt on the material surface to be quickly removed. This invention, after improvement, occupies less space and reduces the volume of the cleaning machine; at the same time, this invention can meet the production speed of stamped parts with a material flow rate of more than 200 times / minute, thus solving the problem of cleaning efficiency; furthermore, the material immediately enters the drying chamber after cleaning in the cleaning tank, thus avoiding secondary contamination after cleaning.

[0004] However, the cleaning device mentioned above cannot circulate and filter the cleaning water during use. After a certain period of use, the cleaning water will contain a lot of oil, resulting in a poor cleaning effect. Secondly, the device cannot achieve tension control and prevent deviation for strips of different thicknesses and widths. During the cleaning process, the strip may bend and turn over, causing the workpiece to deform. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an ultrasonic cleaning device for stamping strips, which has advantages such as good cleaning effect and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning device for stamping strips, comprising a cleaning tank and an ultrasonic generator installed at the bottom of the cleaning tank. A set of transducers is installed on the inner bottom wall of the cleaning tank, and the transducers are electrically connected to the ultrasonic generator. Two tension frames are fixedly connected between the front and rear inner side walls of the cleaning tank. Lifting screws are rotatably connected between the inner top wall and the inner bottom wall of the two tension frames, and fixing frames are threaded onto the outer surfaces of the two lifting screws.

[0007] A set of anti-deviation components for preventing horizontal deviation of the material strip is provided between the middle ends of the two fixing frames;

[0008] A guide assembly is provided between both ends of the two fixing frames;

[0009] A circulating filter assembly is provided on one side of the cleaning tank;

[0010] A cleaning agent replenishment component is provided on one side of the cleaning tank.

[0011] Furthermore, each set of anti-deviation components includes an adjustment frame, with each adjustment frame having its two ends fixedly connected to a nearby fixed frame. A bidirectional lead screw is rotatably connected between the front and rear inner sidewalls of each adjustment frame. An adjustment block is threaded to each end of each bidirectional lead screw. A limit wheel is rotatably connected to the top of each adjustment block. An annular groove is formed on the outer surface of each limit wheel. A limit screw is threaded to the top of one end of each of the two adjustment frames. A bevel gear is fixedly connected to the bottom of the two limit screws and one end of the two bidirectional lead screws. Each pair of adjacent bevel gears are meshed together.

[0012] The above scheme uses a rotating limiting screw to drive a bevel gear transmission, which in turn causes two bidirectional lead screws to rotate. This allows two adjacent limiting wheels to move closer or further apart, thus achieving the purpose of limiting the width of the material belt and preventing it from shifting during the cleaning and conveying process.

[0013] Furthermore, both of the guide components include a bottom roller, with both ends of the two bottom rollers rotatably connected to two fixed frames respectively. An adjusting roller is provided above each of the two bottom rollers, and a thickness block is provided at both ends of each of the two adjusting rollers. Each thickness block abuts against one side of the fixed frame it is close to. A thickness screw is rotatably connected to the top of each thickness block, and each thickness block is threadedly connected to the top of one end of the fixed frame it is close to. Both ends of each adjusting roller are rotatably connected to the thickness block it is close to.

[0014] The above scheme allows for the rotation of the thickness screw, which in turn drives the adjusting roller to rise and fall, thereby guiding material strips of different thicknesses.

[0015] Furthermore, the circulating filtration assembly includes an impurity filter cartridge, a pump body, and a filter. The impurity filter cartridge, pump body, and filter are all fixedly connected to the outer surface of the cleaning tank. A filter screen is slidably inserted into the interior of the impurity filter cartridge. A sealing cap is threadedly connected to the top of the impurity filter cartridge. A filter inlet pipe is fixedly connected to one side of the impurity filter cartridge, and the other end of the filter inlet pipe is fixedly connected to the cleaning tank. A filter outlet pipe is fixedly connected to the other side of the impurity filter cartridge, and the other end of the filter outlet pipe is fixedly connected to the input end of the pump body. The filter outlet pipe and the filter inlet pipe are located on both sides of the filter screen. A purification inlet pipe is fixedly connected to the input end of the filter, and the other end of the purification inlet pipe is fixedly connected to the output end of the pump body. A purification outlet pipe is fixedly connected to the output end of the filter, and the purification outlet pipe is fixedly connected to the cleaning tank. A one-way valve for preventing backflow is installed at one end of both the purification outlet pipe and the filter inlet pipe.

[0016] The above solution, through the setting of the circulating filtration component, can achieve the purpose of circulating and filtering the water inside the cleaning tank. The filter screen can intercept particulate impurities and prevent them from entering the pump body, thus ensuring the service life of the pump body. The filter can filter and purify oil and rust, ensuring the cleanliness of the cleaning water.

[0017] Furthermore, a non-contact liquid level sensor for monitoring the water level inside the cleaning tank is fixedly installed at the top of one side of the cleaning tank, and a clean water metering pump is installed at the top of one side of the cleaning tank. The input end of the clean water metering pump is connected to an external water supply pipe, and the output end of the clean water metering pump is fixedly connected to a clean water replenishment pipe, which is located above the cleaning tank.

[0018] The above solution, through the installation of a non-contact liquid level sensor, enables the monitoring of the water level inside the cleaning tank, and allows for automatic replenishment when the water level drops.

[0019] Furthermore, the cleaning agent replenishment component includes a storage tank, which is fixedly connected to the outer surface of the cleaning tank. An upwardly inclined addition pipe is fixedly connected to the top of the storage tank. A cleaning agent metering pump is installed at the top of the storage tank. An extraction pipe is fixedly connected to the input end of the cleaning agent metering pump and is fixedly connected to the storage tank. A cleaning agent release pipe is fixedly connected to the output end of the cleaning agent metering pump and is located above the cleaning tank.

[0020] With the above solution, the cleaning agent metering pump can automatically draw an appropriate amount of cleaning agent and release it into the cleaning tank based on the added water level, thereby further ensuring the cleaning effect.

[0021] Furthermore, a temperature sensor is installed on the surface of the impurity filter cartridge, and a heater is installed on one side of the cleaning tank, with the heater located inside the cleaning tank.

[0022] The above solution, through the setting of temperature sensors, can achieve the purpose of monitoring the water temperature inside the cleaning tank. Combined with the heater, the water temperature is controlled within a suitable range, thereby improving the cleaning effect on the oil on the surface of the stamping belt.

[0023] Furthermore, a motor is installed at the top of each of the two tension frames, and the output ends of the two motors are respectively fixedly connected to one end of the two lifting screws.

[0024] The above scheme, through the setting of the motor, can drive the anti-deviation component and the guide component to lift and lower, thereby controlling the tension of the hopper.

[0025] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0026] This ultrasonic cleaning device for stamping conveyor belts effectively removes impurities and oil stains from the cleaning fluid through the synergistic action of an ultrasonic generator and transducer, combined with a circulating filtration system. This maintains the cleanliness of the cleaning agent, extends its service life, and reduces resource waste. The anti-deviation component employs a bidirectional adjustment structure to flexibly adapt to conveyor belts of different widths, preventing deviation or twisting during cleaning. The guide component, with its height adjustment design, is compatible with conveyor belts of different thicknesses, preventing warping and ensuring the conveyor belt passes smoothly through the cleaning area. A non-contact liquid level sensor is linked with the cleaning agent replenishment component to achieve a dynamic balance between water level and cleaning agent concentration.

[0048] Please see Figure 1 , Figure 2 and Figure 3A non-contact liquid level sensor 10 for monitoring the water level inside the cleaning tank 1 is fixedly installed on the top of one side of the cleaning tank 1. A clean water metering pump 11 is installed on the top of one side of the cleaning tank 1. The input end of the clean water metering pump 11 is connected to the external water supply pipe, and the output end of the clean water metering pump 11 is fixedly connected to a clean water replenishment pipe 12. The clean water replenishment pipe 12 is located above the cleaning tank 1. With the setting of the non-contact liquid level sensor 10, the water level inside the cleaning tank 1 can be monitored, and the water can be automatically replenished when the water level drops.

[0049] Please see Figure 1 , Figure 2 and Figure 7 A cleaning agent replenishment component 9 is provided on one side of the cleaning tank 1.

[0050] Please see Figure 1 , Figure 2 and Figure 3 A temperature sensor 13 is installed on the surface of the impurity filter cartridge 801, and a heater 14 is installed on one side of the cleaning tank 1. The heater 14 is located inside the cleaning tank 1. By setting the temperature sensor 13, the water temperature inside the cleaning tank 1 can be monitored. With the heater 14, the water temperature can be controlled in a suitable range, thereby improving the cleaning effect on the oil on the surface of the stamping belt.

[0051] This embodiment of an ultrasonic cleaning device for stamping strips utilizes the synergistic effect of an ultrasonic generator 2 and a transducer 201, combined with a circulating filtration system, to effectively remove impurities and oil stains from the cleaning fluid, maintain the cleanliness of the cleaning agent, extend its service life, and reduce resource waste. The anti-deviation component 6 adopts a bidirectional adjustment structure, which can flexibly adapt to strips of different widths, preventing deviation or twisting during the cleaning process. The guide component 7, through its height adjustment design, is compatible with strips of different thicknesses, preventing warping and deformation, and ensuring the strip remains flat. The non-contact liquid level sensor 10 in the cleaning area is linked with the cleaning agent replenishment component 9 to achieve a dynamic balance between water level and cleaning agent concentration. The temperature sensor 13 and heater 14 are set to stably maintain the optimal activity state of the cleaning fluid, enhancing the oil stain removal effect.

[0052] The working principle of the above embodiment is as follows: The ultrasonic generator 2 converts high-frequency electrical oscillations into mechanical vibrations through the transducer 201, generating high-frequency sound waves in the cleaning tank 1. The sound waves create a cavitation effect in the liquid, that is, the alternating action of high and low pressure generates microbubbles. When the bubbles close, they release shock waves, peeling off impurities such as oil and metal fragments from the surface of the material belt, and pushing the peeled dirt off the surface of the material belt. The distance between the two sets of limit wheels 604 is adjusted by the linkage between the bidirectional screw 602 and the bevel gear 607, so that the material belt is kept in the center position in the annular groove 605. The bottom roller 701 cooperates with the adjustable adjusting roller 702. By rotating the thickness screw 704, the height of the adjusting roller 702 is changed to adapt to material belts of different thicknesses and prevent warping. The motor 15 drives the lifting screw 4 to control the overall lifting of the fixed frame 5, dynamically adjusting the tension of the material belt and avoiding the material belt from warping due to insufficient tension. With relaxed or excessively stretched deformation, the cleaning fluid enters the impurity filter cartridge 801 through the filter inlet pipe 806, where large particles of impurities are intercepted by the filter screen 804. The pump body 802 draws the initially filtered liquid to the filter 803, and after purifying the oil and rust, it flows back to the cleaning tank 1 through the purification outlet pipe 809. A one-way valve prevents backflow of the liquid and maintains unidirectional flow in the circulation path. A non-contact liquid level sensor 10 monitors the water level. When the liquid level is lower than the threshold, it triggers the clean water metering pump 11 to automatically replenish water through the clean water replenishment pipe 12. The cleaning agent metering pump 903 draws the cleaning agent in the storage tank 901 proportionally according to the change in water level and adds it synchronously through the release pipe to ensure a constant cleaning fluid concentration. The temperature sensor 13 monitors the cleaning fluid temperature in real time. If it is lower than the set value, the heater 14 starts to heat up, improving the oil dissolution efficiency; it automatically shuts off after reaching the temperature, saving energy and reducing consumption.
