Specific embodiments

[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A cleaning mechanism for a coiled steel strip, comprising: a cleaning tank 101 storing lye therein; a conveying mechanism including an unwinder 201 and a rewinder 202 disposed on both sides of the cleaning tank 101, and a guiding mechanism disposed in the cleaning tank 101, the guiding mechanism including a plurality of guide rollers 203 spaced apart in the cleaning tank 101, and any guide roller 203 is rotatably connected to the cleaning tank 101. Installing a plurality of guide rollers 203 in the cleaning tank 101 is convenient for conveying the steel strip 601 on the one hand; on the other hand, it can make the part of the steel strip 601 in the cleaning tank 101 be in the lye, which is convenient for the lye to clean the surface of the steel strip 601; on the other hand, the number of guide rollers 203 can be designed according to the actual situation to increase the length of the steel strip 601 in the lye, so that the lye can clean a longer length of the steel strip 601 at the same time.

[0025] The lye heating mechanism 301 is disposed in the cleaning tank 101. Using the lye heating mechanism 301 to heat the lye, the lye with a certain temperature has a better cleaning effect on the steel strip 601.

[0026] A cleaning mechanism 401 is disposed on the cleaning tank 101 and is disposed close to the rewinder 202; the steel strip 601 on the unwinder 201 passes through the guiding mechanism and the cleaning mechanism 401 in sequence and then is connected to the rewinder 202.

[0027] Referring to Figure 1 and Figure 2

[0027] , the cleaning mechanism 401 includes two cleaning rollers 4011 arranged symmetrically and spaced apart. Both cleaning rollers 4011 are rotatably connected to the cleaning tank 101; the steel strip 601 after cleaning passes through the area between the two cleaning rollers 4011 and then is connected to the coiling machine 202; both cleaning rollers 4011 are drivingly connected to a driving mechanism, and this driving mechanism can be a motor; the cross-section of any cleaning roller 4011 is a regular polygon, and the cleaning surface of any cleaning roller 4011 is covered with cleaning cotton 4012, and the cleaning cotton 4012 at corresponding positions on the two cleaning rollers 4011 can be in contact with the steel strip 601 simultaneously.

[0028] Designing the cleaning mechanism 401 in this structure facilitates cleaning the surface of the steel strip 601 after cleaning to remove solid particles or cleaning liquid remaining on the surface of the steel strip 601. Specifically, there should be a certain interval between the two cleaning rollers 4011, and when one cleaning roller 4011 rotates, the other cleaning roller 4011 will not affect its rotation. The thickness of the cleaning cotton 4012 can be selected according to the thickness of the steel strip 601, so that when the steel strip 601 passes through the area between the two cleaning rollers 4011, the cleaning cotton 4012 on the two cleaning rollers 4011 is in close contact with the steel strip 601. Using cleaning cotton 4012 with different thicknesses simultaneously can adapt to steel strips 601 with different thicknesses. When the cleaning cotton 4012 on the current cleaning roller 4011 gets dirty, the driving mechanism can control the cleaning roller 4011 to rotate a certain angle, so that the clean cleaning cotton 4012 contacts the steel strip 601 in sequence, which can improve the cleaning effect of the steel strip 601. For example, when the cross-section of the cleaning roller 4011 is a square, the driving mechanism controls the cleaning roller 4011 to rotate 90 degrees each time, and the clean cleaning cotton 4012 contacts the steel strip 601 in sequence. After the cleaning roller 4011 rotates four times, all the cleaning cotton 4012 is soiled by dirt, and at this time, just replace the clean cleaning cotton 4012.

[0029] To further improve the cleanliness of the surface of the steel strip 601 after being cleaned by the alkali solution, the cleaning mechanism 401 further includes a scraping mechanism 501 installed in the cleaning tank 101, and the scraping mechanism 501 is arranged close to the coiling machine 202; the steel strip 601 after cleaning passes through the scraping mechanism 501 and the cleaning mechanism 401 in sequence and then is connected to the coiling machine 202. In this way, the steel strip 601 after being cleaned by the alkali solution first passes through the scraping mechanism 501, and the scraping mechanism 501 scrapes off most of the solid particles and liquid on the steel strip 601, and then is further cleaned and wiped dry by the cleaning mechanism 401 to improve the cleanliness of the surface of the steel strip 601.

[0030] Specifically, referring to Figure 1 and Figure 3, the scraping mechanism 501 includes two symmetrically installed scraping plates 5011, and the two scraping plates 5011 are connected to the cleaning tank 101 through two connecting rods 5012; the distance between the scraping ends of the two scraping plates 5011 is equal to the thickness of the steel belt 601. When designing, the scraping end of each scraping plate 5011 can be designed as a tip structure.

[0031] In order to ensure that the scraping ends of the two scraping plates 5011 are always in contact with the steel belt 601 to improve the scraping effect; at the same time, the scraping mechanism 501 should be adapted to steel belts 601 of different thicknesses, so the two connecting rods 5012 are designed as telescopic structures; a spring 5013 is sleeved on the connecting rod 5012, one end of the spring 5013 is connected to the scraping plate 5011, and the other end is connected to the cleaning tank 101. In this way, the scraping ends of the two scraping plates 5011 are always in contact with the steel belt 601 under the action of the two springs 5013.

[0032] Specifically, referring to Figure 1 and Figure 4 , in this embodiment, the lye heating mechanism 301 is a coil 3011 installed at the bottom of the cleaning tank 101, and both ends of the coil 3011 are connected to a hot water delivery unit. The supporting hot water delivery unit first heats the water to a certain temperature, then injects the water into the coil 3011 through one end of the coil 3011, and the hot water then flows back into the hot water delivery unit from the other end of the coil 3011, forming a circulating flow. After the hot water enters the coil 3011, it transfers heat to the lye through the coil 3011 to heat the lye.

[0033] In order to further improve the heat transfer efficiency, a number of heat dissipation fins 3012 are arranged at intervals on the coil 3011.

[0034] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
