Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum processing, and particularly relates to a cleaning mechanism for a stretcher leveller train. Background Art

[0002] The main functions of an aluminum and aluminum alloy strip stretcher leveller train are to clean the surface quality of the strip and correct the plate shape, among which the cleaning function is crucial. During the previous process of rolling aluminum and aluminum alloy strips, aluminum ash, sludge, etc. will be generated on the surface, and it is necessary to process the surface through a cleaning process to meet the requirements of the next process. At the same time, it also supports the subsequent stretcher levelling function. If there is a serious problem of aluminum ash, sludge, etc. on the strip surface, it will directly lead to defects such as stretcher pitting and color difference in the next process. Therefore, the cleaning function is one of the main functions of the stretcher leveller, and its cleaning ability directly affects the product quality.

[0003] Conventional aluminum and aluminum alloy strip stretcher leveller trains are all equipped with a high-pressure cleaning and a low-pressure rinsing section to clean the surface of the strip. In recent years, with the continuous improvement of the market's requirements for the surface quality of aluminum sheet strips, some stretcher leveller trains have added chemical cleaning to improve the cleaning quality. The traditional method is through high-pressure cleaning plus low-pressure rinsing. The water for high-pressure cleaning is recycled through a plate filter. If there is chemical cleaning, such as alkali cleaning, the cleaning medium in the alkali cleaning section will still be recycled after filtration. In the actual production process, the aluminum ash, sludge, etc. washed down will accumulate and block at the nozzles, resulting in unstable cleaning quality of the strip. Due to the existing water tank structure form, it is impossible to directly judge the nozzle blockage situation, so the method of regular inspection, dredging, and cleaning of the nozzles is adopted to ensure the cleaning quality, which brings uncertainty to the stable cleaning quality and increases the maintenance workload.

[0004] Therefore, there is an urgent need for a cleaning mechanism for a leveller train with a low blockage probability and stable cleaning quality. Summary of the Utility Model

[0005] In view of the above deficiencies existing in the prior art, the utility model provides a cleaning mechanism for a stretcher leveller train, aiming to solve the problems of easy blockage, unstable cleaning quality, and affecting product quality of the existing cleaning mechanism.

[0006] To achieve the above object, the utility model is configured as follows:

A number of evenly spaced nozzles are provided on the lower side of the spraying section of the spray pipe. The water outlet of the nozzle is gradually expanded outward. A drain port is provided on the lower side of the water outlet end of the spray pipe. A baffle with through holes is arranged in the spray pipe. The baffle is located between the nozzle and the drain port. A cross bar is arranged in the spray pipe. A plug is provided at one end of the cross bar close to the baffle. The plug is used to block the through hole on the baffle. A number of staggered brushes are arranged on the outer side of the cross bar. One brush corresponds to one nozzle.

In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicating the orientation or position relationship, they are based on the orientation or position relationship shown in the figure, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0025] Such as Figure 1-2As shown in the figure, the utility model discloses a cleaning mechanism for a stretch-bending straightening machine train, which includes a spray pipe 1. A number of evenly spaced nozzles 2 are installed on the lower side of the spraying section of the spray pipe 1. The water outlet of the nozzle 2 is gradually expanded outwards, and external pollutants are not easily attached to the nozzle 2. A drain port 3 is arranged on the lower side of the left end of the spray pipe 1. A baffle 4 with through holes is arranged in the spray pipe 1. The baffle 4 is located between the nozzle 2 and the drain port 3. A cross bar 5 is arranged in the spray pipe 1. One end of the cross bar 5 close to the baffle 4 is fixedly connected with a plug, and the plug is used to block the through hole on the baffle 4.

The spray pipe 1 is also equipped with a driving mechanism, and the driving mechanism is used to drive the cross bar 5 to rotate and move left and right.

[0026] As a preference of this embodiment, the driving mechanism includes a handle 7. One end of the cross bar 5 far from the plug penetrates through the spray pipe 1 and is fixedly connected with the handle 7. A sealing rubber ring is arranged at the connection between the cross bar 5 and the spray pipe 1.

[0027] As a preference of this embodiment, the cross bar 5 in the spray pipe 1 is rotatably connected with a bearing 12, and three support rods fixedly connected with the spray pipe 1 are arranged on the outer side of the bearing 12.

[0030] As a preference of this embodiment, a support frame 13 is arranged at the water outlet end of the spray pipe 1.

[0031] The operation process of the cleaning mechanism for the stretch-bending straightening machine train of the utility model is as follows:

[0032] When the nozzle 2 is not cleaned, the cross bar 5 is driven to move leftwards through the handle 7, so that the plug at the left end of the cross bar 5 abuts against the through hole of the baffle 4. At this time, the brush 6 is misaligned with the nozzle, and the brush 6 will not affect the cleaning work of the nozzle.

[0033] When the nozzle 2 is cleaned, the cross bar 5 is driven to move rightwards through the handle 7, and the plug at the left end of the cross bar 5 is separated from the through hole of the baffle 4. At the same time, each brush 6 moves to directly above the corresponding nozzle, and then the handle 7 is rotated.
