Description
Technical Field
[0001] This utility model relates to the field of aluminum strip processing equipment, and in particular to an aluminum strip surface cleaning line. Background Technology
[0002] The aluminum strip cleaning line is a specialized production line designed to meet the surface cleaning needs of aluminum strips. Its core function is to remove impurities such as oil, dust, and oxides from the surface of aluminum strips through a series of processes including degreasing, cleaning, and drying, thereby improving surface cleanliness and quality.
[0003] Existing aluminum strip cleaning lines typically consist of an unwinding device, a degreasing mechanism, an ultrasonic high-pressure spray cleaning system, a drying and cooling unit, and a winding device. Through mechanized continuous operation, they achieve the entire process of aluminum strip processing, from unwinding to cleaning, drying, and winding.
[0004] Existing aluminum strip cleaning lines are typically fixed in size. When the conveying speed of the aluminum strip increases during the cleaning process, the contact time between the aluminum strip and the cleaning rollers is shortened. This limits the running speed of the aluminum strip in the cleaning line, thus affecting the efficiency of the aluminum strip cleaning and conveying process. Utility Model Content
[0005] To overcome the problem that existing aluminum strip cleaning lines are usually of fixed size, and that when the conveying speed of the aluminum strip increases during the conveying process inside the cleaning line, the contact time between the aluminum strip and the cleaning roller is shortened, thus limiting the running speed of the aluminum strip in the cleaning line and affecting the cleaning and conveying efficiency of the aluminum strip.
[0006] The technical solution of this utility model is as follows: an aluminum strip cleaning line, comprising a cleaning box, a hot air box, a cold air box, a take-up roller, a second water pump, and a third water pump. Several cleaning boxes are linearly distributed with the hot air box, cold air box, and take-up roller. Each cleaning box has a clamping assembly on its inner wall. Each clamping assembly includes a first mounting base fixed to the inner wall of the cleaning box. Two first limiting rollers are rotatably connected to the center of the first mounting base. A first motor is fixed to the side wall of each first mounting base. Several [unclear - possibly related to a specific type of motor] are inserted into the inner wall of the cleaning box. The first set of spray pipes, the second water pump, and the third water pump are respectively fixed on the ground near the spray pipes of the cleaning tank. Four sets of cleaning components are installed on the inner wall of the cleaning tank near the spray pipes. Each of the four cleaning components includes a second mounting base fixed on the inner wall of the cleaning tank. A brush roller is rotatably connected to the inner wall of the second mounting base. A second limiting roller is rotatably connected to the side wall of the second mounting base near the brush roller. A second motor is fixed on the side wall of the second mounting base. Gears are fixed at the ends of the brush roller and the second limiting roller away from the second motor.
[0007] Furthermore, the four second mounting seats are divided into two groups and linearly distributed on the inner wall of the cleaning box near the spray pipe. Each group of second mounting seats is fixed in reverse order. The output end of the second motor passes through the cleaning box and is fixed to one end of the brush roller. The gears mesh with each other, which improves the stability of aluminum strip cleaning.
[0008] Furthermore, several first mounting seats are distributed and fixed on the inner side wall of the cleaning box near the end. Each first mounting seat has a baffle fixed on its side wall. The outer surface of each first limiting roller is covered with an anti-slip sleeve. The output end of the first motor passes through the cleaning box and is fixed to the end of the first limiting roller, which improves the stability of the aluminum strip conveying.
[0009] Furthermore, two sets of squeezing components are installed on the inner wall of the cleaning box near the cold air box. Each squeezing component includes a third mounting base fixed on the inner wall of the cleaning box. Two third motors are fixed on the side wall of each third mounting base. Each output end of the third motor is fixed with a squeezing roller, which reduces the moisture on the surface of the aluminum strip.
[0010] Furthermore, the three cleaning tanks are connected in sequence at their ends, and the bottom of each cleaning tank is funnel-shaped. A sedimentation tank is installed at the bottom of each cleaning tank, which improves the convenience of wastewater collection.
[0011] Furthermore, pipes are inserted into the top of each sedimentation tank to connect with the cleaning tank, filter screens are clipped onto the inner side wall of the sedimentation tank, and a first water pump is fixed on the side wall of each sedimentation tank. The output end of the first water pump is connected to the water supply tank in sequence, which improves the efficiency of wastewater circulation.
[0012] Furthermore, an electric heating generator is fixedly installed on the side wall of the hot air box, and two sets of first air outlets are fixedly installed on the inner side wall of the hot air box. A filter is inserted into the side wall of the hot air box, and the two ends of the cooling fan are connected to the first air outlets and the filter respectively, thereby reducing heat loss.
[0013] Furthermore, a cooling fan is fixedly installed on the side wall of the cold air box, and two sets of second air outlets are fixedly installed on the inner side wall of the cold air box, with the output end of the cooling fan connected to the second air outlet respectively.
[0014] The beneficial effects of this utility model are:
[0015] Compared to traditional aluminum strip cleaning lines, this system features a clamping and conveying assembly. Starting the first motor drives two first limiting rollers to rotate in opposite directions, improving the efficiency of aluminum strip clamping and conveying. A cleaning assembly also includes a second motor that, through gear engagement, drives a brush roller and a second limiting roller to rotate synchronously in opposite directions, increasing the efficiency of cleaning the bottom and surface of the aluminum strip. The modular design of the cleaning box, spray pipe, first mounting base, and second mounting base enhances the ease of extending the aluminum strip cleaning line, allowing for faster conveying while ensuring thorough cleaning, thus improving cleaning efficiency. Furthermore, the system incorporates anti-slip sleeves and baffles. The anti-slip sleeves, made of rubber with anti-slip stripes, increase friction resistance and improve the stability of aluminum strip clamping and conveying. The baffles, made of plastic, prevent cleaning water from splashing and contaminating the cleaning box. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Among the currently discovered feasible technologies, the following are described:
[0024] Aluminum strip is widely used in modern industry, covering aerospace, automobile manufacturing, electronics, packaging and other fields. As downstream industries continue to increase their requirements for the surface quality of aluminum strip, the aluminum strip cleaning line, as a key piece of equipment in the aluminum processing production process, is becoming increasingly important. The aluminum strip cleaning line is usually composed of four main parts: inlet section, cleaning section, drying section and outlet section. Each part works together through an automated control system to ensure the cleaning quality and production efficiency of the aluminum strip.
[0025] The entry section mainly includes equipment such as an uncoiler, a straightener, a head cutter, and a sewing machine. The uncoiler is used to unwind the aluminum strip coil, providing a continuous supply of aluminum strip for the subsequent cleaning process. The straightener straightens the aluminum strip, eliminating shape defects such as waviness and warping generated during the rolling process, ensuring that the strip can pass smoothly through the cleaning section. The head cutter is used to remove irregular parts at the head of the aluminum strip, so that the strip can smoothly enter the sewing machine. The sewing machine is used to sew the tail of the previous coil of strip to the head of the next coil of strip, realizing continuous production, reducing downtime, and improving production efficiency.
[0026] The cleaning section is the core part of the aluminum strip cleaning line. Its main function is to remove impurities such as oil, dust, and rolling residues from the surface of the aluminum strip.
[0027] The pre-cleaning tank contains an alkaline cleaning solution of a certain concentration. The aluminum strip first enters the pre-cleaning tank, where it is immersed and undergoes a preliminary chemical reaction to remove most of the oil and loose impurities from its surface. The concentration, temperature, and immersion time of the alkaline cleaning solution are key factors affecting the pre-cleaning effect and usually need to be adjusted according to the degree of surface contamination of the aluminum strip. The concentration and temperature of the cleaning solution in the main cleaning tank are usually higher than those in the pre-cleaning tank to further remove stubborn impurities from the strip surface. The main cleaning tank is generally equipped with a brushing device consisting of multiple brush rollers rotating in the opposite direction to the running direction of the aluminum strip. Through the combined action of mechanical friction and the cleaning solution, the cleaning effect is improved. The material and hardness of the brush rollers need to be selected according to the thickness and surface quality requirements of the aluminum strip to avoid damaging the strip surface.
[0028] Spray systems are typically installed at the outlets of the pre-cleaning tank and the main cleaning tank to rinse the strip surface and remove residual cleaning solution and impurities. Filtered clean water is generally used for the spray to ensure effective rinsing. The spray pressure and flow rate need to be adjusted according to the strip's operating speed and cleaning requirements.
[0029] A circulating filtration system is used to circulate and filter the cleaning solution to maintain its cleanliness and concentration. A circulating filtration system typically includes a filter, a circulating pump, and a level control system. The filter is used to remove impurities from the cleaning solution, while the circulating pump is used to draw the cleaning solution out of the cleaning tank, filter it, and then return it to the cleaning tank.
[0030] The purpose of the drying section is to remove moisture from the surface of the cleaned aluminum strip to prevent corrosion during subsequent processing and storage. The drying section typically uses hot air drying and mainly includes a hot air blower, heater, hot air nozzles, and an exhaust system. The hot air blower sends air into the heater for heating, and the heated hot air is then blown onto the aluminum strip surface at a specific speed and angle through the hot air nozzles, causing the surface moisture to evaporate rapidly. The exhaust system removes the moisture generated during the drying process, maintaining air circulation within the drying section. The temperature, air velocity, and drying time of the hot air are key factors affecting the drying effect and need to be adjusted according to the thickness and surface moisture content of the aluminum strip.
[0031] Please refer to Figures 1-5A cleaning line for aluminum strip includes a cleaning box 1, a hot air box 6, a cold air box 7, a take-up roller 8, a second water pump 11, and a third water pump 12. Several cleaning boxes 1 are linearly distributed with the hot air box 6, cold air box 7, and take-up roller 8. Each cleaning box 1 has a clamping assembly 2 on its inner wall. Each clamping assembly 2 includes a first mounting base 201 fixed to the inner wall of the cleaning box 1. Several first mounting bases 201 are distributed and fixed on the inner wall of the cleaning box 1 near its end. Two first limiting rollers 202 are rotatably connected to the middle of each first mounting base 201. The aluminum strip passes sequentially between the two first limiting rollers 202. A first motor 203 is fixed to the side wall of each first mounting base 201. The output end of a motor 203 is sequentially fixed to the end of the first limiting roller 202 through the cleaning tank 1. Starting the first motor 203 can drive the two first limiting rollers 202 to rotate in opposite directions, thereby improving the efficiency of aluminum plate conveying. Several sets of spray pipes 3 are inserted into the inner wall of the cleaning tank 1. The spray pipes 3 are evenly distributed in a U-shape for the aluminum strip to pass through. Several sets of nozzles are inserted into the inner wall of the spray pipes 3 to atomize the cleaning water. The second water pump 11 and the third water pump 12 are respectively fixed on the ground of the cleaning tank 1 near the spray pipes 3. The input ends of the second water pump 11 and the third water pump 12 are respectively connected to the water supply tank. The water supply tank is filled with weakly alkaline water. The water supply tank and the weakly alkaline water are both existing technologies. The details will not be elaborated here. The third water pump 12 is connected to the spray pipe 3 at the front of the cleaning tank 1 to spray low-pressure water. The second water pump 11 is connected to the spray pipe 3 at the rear of the cleaning tank 1 to spray high-pressure water to rinse the aluminum strip. Four sets of cleaning components 4 are provided on the inner wall of the cleaning tank 1 near the spray pipe 3. Each of the four cleaning components 4 includes a second mounting base 401 fixed on the inner wall of the cleaning tank 1. A brush roller 402 is rotatably connected to the inner wall of the second mounting base 401. A second limiting roller 403 is rotatably connected to the side wall of the second mounting base 401 near the brush roller 402. A second motor 404 is fixed on the side wall of the second mounting base 401. Gears 405 are fixed at the ends of the second limiting roller 403 away from the second motor 404. The four second mounting seats 401 are divided into two groups and linearly distributed on the inner wall of the cleaning box 1 near the spray pipe 3. Each group of second mounting seats 401 is fixed in reverse order. The output end of the second motor 404 passes through the cleaning box 1 and is fixed at one end of the brush roller 402. The gears 405 mesh with each other, which improves the stability of aluminum strip cleaning. The modular arrangement of the cleaning box 1, spray pipe 3, first mounting seat 201 and second mounting seat 401 improves the convenience of extending the aluminum strip surface cleaning line, thereby facilitating the acceleration of the aluminum strip conveying line speed and ensuring that the aluminum strip is fully cleaned, thereby improving the aluminum strip conveying efficiency.
[0032] Each side wall is fixed with a baffle 205, which is made of plastic and is used to block the sprayed cleaning water. The outer surface of the first limiting roller 202 is covered with an anti-slip sleeve 204, which is made of rubber and has anti-slip stripes on its surface, thus improving the stability of the aluminum strip conveyor.
[0033] Three cleaning tanks 1 are connected in sequence at their ends. The bottom of each cleaning tank 1 is funnel-shaped. A sedimentation tank 9 is installed at the bottom of each cleaning tank 1, which improves the convenience of wastewater collection. The top of each sedimentation tank 9 is connected to a pipe that is connected to the cleaning tank 1. A filter screen 15 is clipped onto the inner side wall of the sedimentation tank 9. A first water pump 10 is fixed on the side wall of each sedimentation tank 9. The output end of the first water pump 10 is connected to the water supply tank in sequence, which improves the efficiency of wastewater circulation.
[0034] Two sets of squeezing components 5 are installed on the inner wall of the cleaning box 1 near the cold air box 7. Each squeezing component 5 includes a third mounting base 501 fixed to the inner wall of the cleaning box 1. Two third motors 503 are fixed to the side wall of each third mounting base 501. Each output end of the third motor 503 is fixed with a squeezing roller 502, which reduces the moisture on the surface of the aluminum strip. An electric heating generator 16 is fixed to the side wall of the hot air box 6. The electric heating generator 16 is activated to provide hot air. Two sets of first outlet... The air outlet 13 is symmetrically distributed and used to blow on both sides of the aluminum strip plate. A filter 18 is inserted into the side wall of the hot air box 6 to filter the moisture in the warm air. The two ends of the cooling fan 17 are connected to the first air outlet 13 and the filter 18 respectively, so as to facilitate the circulation of warm air inside the cooling air box 7 and reduce heat loss. The cooling fan 17 is fixed on the side wall of the cooling air box 7. Two sets of second air outlets 14 are fixed on the inner side wall of the cooling air box 7. The output end of the cooling fan 17 is connected to the second air outlet 14 respectively.
[0035] When using this aluminum strip cleaning line, the operator moves the device to the designated position and connects the external power supply. One end of the aluminum strip is inserted between the two first limiting rollers 202, passing through the cleaning box 1, hot air box 6, and cold air box 7 in sequence, and then wound around the outer surface of the take-up roller 8. The operator starts the line, and the first motor 203 drives the two first limiting rollers 202 to rotate in opposite directions, improving the stability of the horizontal conveying of the aluminum strip. Then, the third water pump 12 is started to spray weakly alkaline water evenly onto the surface and bottom of the aluminum strip through the spray pipe 3 at the front of the cleaning box 1. Then, the second motor 404 is started, which, through the gear 405, drives the brush roller 402 and the second limiting roller 403 to rotate synchronously in opposite directions, thereby causing the brush roller 402 to rotate in opposite directions. 02. The bottom and surface of the aluminum strip are cleaned sequentially. The second water pump 11 is started, and high-pressure water is sprayed through the spray pipe 3 to wash away the attached impurities, thereby improving the cleaning efficiency of the aluminum strip. After cleaning, the aluminum strip enters between the extrusion rollers 502 to squeeze out the water attached to the surface of the aluminum strip. Then it enters the hot air box 6 and the cold air box 7 to blow warm air and cold air respectively to dry it. The cleaned aluminum strip is then wound on the outer surface of the winding roller 8. The modular setting of the cleaning box 1, spray pipe 3, first mounting base 201 and second mounting base 401 improves the convenience of extending the aluminum strip surface cleaning line, thereby facilitating the acceleration of the aluminum strip conveying line and ensuring that the aluminum strip is thoroughly cleaned, thus improving the conveying efficiency of the aluminum strip.
[0036] Considering the instability of clamping the aluminum strip when it moves at high speed, an anti-slip sleeve 204 and a baffle 205 are provided. The anti-slip sleeve 204 is made of rubber and has anti-slip stripes on its surface to increase friction resistance and improve the stability of clamping and conveying the aluminum strip. The baffle 205 is made of plastic to prevent cleaning water from splashing and contaminating from both ends of the cleaning tank 1.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
