Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and in particular to a cleaning device and a control method for metal plates and strips. Background Art

[0002] During the metal processing and manufacturing process, the rolled metal sheets and strips will be degreased and cleaned, and the metal sheets and strips will be brushed with a brush roller to efficiently and quickly remove oil stains, oxides, etc. on the surface of the metal sheets and strips.

[0003] The brush roller gap of the existing cleaning device is often fixed after being adjusted according to the metal plate and strip to be cleaned during cleaning. Due to the different thicknesses or surface roughness of the metal plates and strips, when the brush roller gap is larger, cleaning is not in place and the cleaning effect is poor. When the brush roller gap is smaller, the brush wire on the brush roller will scratch the surface of the metal plate and strip, causing damage to the metal plate and strip.

[0004] Therefore, it is necessary to further explore and practice the above technical issues. Summary of the Invention

[0005] (1) Technical issues to be resolved

[0006] The technical problem to be solved by the present invention is to provide a cleaning device for metal plates and strips, which can automatically adjust to a suitable roller gap according to the thickness or surface roughness of the metal plates and strips, and can not only complete the cleaning efficiently, but also will not cause damage to the metal plates and strips.

[0007] (2) Technical solution

[0008] The technical solution adopted by the present invention to solve the above problems is:

[0009] A cleaning device for metal plates and strips, comprising a housing, wherein a brush roller assembly, an inlet pinch roller assembly, and an outlet pinch roller assembly are provided in the housing, the inlet pinch roller assembly and the outlet pinch roller assembly being arranged on both sides of the brush roller assembly;

[0010] The inlet pinch roller assembly includes an upper inlet pinch roller and a lower inlet pinch roller, a first control mechanism is provided between the upper inlet pinch roller and the top of the box, and a first sensor is provided on the first control mechanism;

[0011] The brush roller assembly includes an upper brush roller and a lower brush roller, a second control mechanism is provided between the upper brush roller and the top of the box, a controller and a second sensor are provided on the second control mechanism, and the controller is matched and connected with the first sensor and the second sensor;

[0012] The outlet pinch roller assembly includes an upper outlet pinch roller and a lower outlet pinch roller. A third control mechanism is provided between the upper outlet pinch roller and the top of the box body. The third control mechanism is matched and connected with the controller.

[0013] In the above technical solution, the metal sheet and strip are fed into the inlet pinch roller assembly, and the upper inlet pinch roller moves under the action of the metal sheet and strip and is affected by the different thicknesses or surface roughness of the metal sheet and strip, and moves up and down irregularly. The first sensor transmits a signal to the controller, and the controller continuously records the changing roller gap distance; when the metal sheet and strip reaches the brush roller assembly, the second sensor transmits a signal to the controller, and the controller records the time again and calculates the time interval; the controller controls the second control mechanism to make the upper brush roller start to move up and down at an irregularly changing distance, so that the roller gap distance of the inlet pinch roller assembly is consistent with the roller gap distance of the brush roller assembly after the time interval;

[0014] The controller continuously obtains the current maximum value which will also change based on the distance that has appeared; the controller controls the third control mechanism so that the roller gap distance of the exit pinch roller assembly is adjusted to the current maximum value, which can prevent the metal sheet and strip from curling during movement, and finally passes through the exit pinch roller assembly to complete surface cleaning.

[0015] Furthermore, the upper brush roller and the lower brush roller each include a roller body and a nylon brush arranged outside the roller body.

[0016] Furthermore, a fourth control mechanism is provided between the lower brush roller and the bottom of the box body, and a control valve is provided on both the second control mechanism and the fourth control mechanism.

[0017] In the above technical solution, since the nylon brush on the outside of the brush roller will be worn out during use, the distance between the upper brush roller and the lower brush roller can be easily readjusted by using the control valve.

[0018] Furthermore, it also includes a driving mechanism that cooperates with the brush roller assembly.

[0019] In the above technical solution, the driving mechanism drives the inlet pinch roller assembly, the brush roller assembly and the outlet pinch roller assembly to rotate.

[0020] The present invention also provides a method for controlling a cleaning device for metal plates and strips, comprising the following steps:

[0021] S1, providing a cleaning device for metal plates and strips according to the above technical solution;

[0022] S2, in the initial state, the roller gaps between the inlet pinch roller assembly, the brush roller assembly and the outlet pinch roller assembly are infinitely close to 0, and the rotation is maintained;

[0023] S3: The metal strip is fed into the entrance pinch roller assembly. The upper entrance pinch roller moves under the action of the metal strip and is affected by the thickness or surface roughness of the metal strip, causing it to move up and down irregularly. The first sensor transmits a signal to the controller, which records the time t1 and the roller gap distance d1 of the entrance pinch roller assembly that continues to change irregularly.

[0024] S3, when the metal sheet and strip moves to the brush roller assembly under the action of the inlet pinch roller assembly, the second sensor transmits a signal to the controller, the controller records the time t2, and calculates the time interval t3, t3 = t2-t1;

[0025] S4, the controller controls the second control mechanism to make the upper brush roller start to move up and down at an irregularly changing distance d1, so that the gap distance of the inlet pinch roller assembly is consistent with the gap distance of the brush roller assembly after the time interval t3;

[0026] S5, the controller continues to obtain the current maximum value d2 which will also change based on the distance d1 that has appeared;

[0027] S6, the controller controls the third control mechanism so that the roller gap distance of the outlet pinch roller assembly is adjusted to d2;

[0028] S7, the metal sheet and strip passes through the brush roller assembly and then the outlet pinch roller assembly to complete the surface cleaning.

[0029] Furthermore, after the cleaning is completed in step S7, the roller gap distance d1 of the inlet pinch roller assembly is restored to the initial state in step S1; the nylon brush on the brush roller assembly will become shorter due to friction with the metal sheet and strip, and by adjusting the control valve, the roller gap distance of the brush roller assembly is also restored to the initial state in step S1.

[0030] (3) Beneficial effects

[0031] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0032] The present invention provides a cleaning device and control method for metal plates and strips, which can automatically adjust to a suitable roller gap according to the thickness or surface roughness of the metal plates and strips, thereby efficiently completing cleaning without causing damage to the metal plates and strips.
