Description

Technical Field

[0001] This utility model relates to the field of battery electrode rolling technology, specifically to an online roller surface humidity detection device. Background Technology

[0002] Currently, the main method for wiping the rollers of lithium electrode sheet roll forming machines in the industry is to spray solvent onto the main roller and then use a scraper to remove the wastewater from the roller surface. However, the electrode sheets have extremely high requirements for the humidity of the roller surface. If the humidity of the roller surface exceeds the standard or the scraper fails (such as long-term wear or damage caused by large particles sticking to the roller, resulting in gaps), solvent residue on the roller surface may cause a large area of ​​electrode sheets to be scrapped. Therefore, real-time monitoring of the humidity of the roller surface is an important measure to prevent the scrapping of electrode sheets, but there is currently no good method or the detection device is too expensive to be applicable. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a low-cost device that can monitor the humidity of online rolling mill rolls in real time. When the humidity of the roll surface exceeds the standard, it can detect and alarm in a timely manner, preventing the large-scale scrapping of electrode sheets.

[0006] The support plate and the fixing plate 31 are arranged opposite to each other, and a humidity sensor bracket 36 is placed between them. The two ends of the humidity sensor bracket 36 are respectively connected to the support plate and the fixing plate 31. The outer ends of the humidity sensor bracket are provided with bearing seats 310, and the two ends of the sponge roller are respectively connected to the corresponding bearing seats through bearings.

[0007] The humidity sensor 38 is installed between the sponge roller 39 and the humidity sensor bracket 36. It is connected to the outside of the humidity sensor bracket 36 and faces the sponge roller through the humidity sensor pad 37.

[0008] Furthermore, the humidity sensor pad is made of a non-metallic material.

[0009] Furthermore, the humidity sensor pad is made of nylon.

[0010] Furthermore, it also includes a linear drive assembly; both sides of the humidity sensor pad are provided with sliding holes for mating with the bearing seat 310, the sliding holes vertically penetrate the humidity sensor pad, and the bearing seat 310 has the freedom to move along the central axis of the sliding hole; the linear drive assembly is mounted on a support plate or a fixed plate, and its actuating end is connected to the bearing seat 310 on the same side.

[0011] Furthermore, it also includes a sliding plate; the bearing seat 310 is fixed on the corresponding sliding plate, and one end of the sliding plate passes through the sliding hole and is constrained to the linear guide rail on the support plate or fixed plate.

[0012] Furthermore, the linear drive assembly is a cylinder 32, which is mounted on the inner side of the fixed plate via a cylinder bracket 33; the piston rod of the cylinder 32 is connected to the sliding plate, driving the sliding plate to slide along the linear guide rail.

[0013] Furthermore, both the inner side of the support plate and the inner side of the fixing plate are provided with linear guide rails, and the two linear guide rails are parallel to each other.

[0014] Furthermore, it also includes a PLC, which acts as a controller and is connected to an alarm and a humidity sensor, which act as actuators, to form an automatic control system.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This patent utilizes a highly absorbent sponge roller as a medium. The sponge roller adheres to the main roller and absorbs moisture from the roller surface. At regular intervals, the sponge roller is brought into contact with a humidity sensor. By detecting the humidity of the sponge roller, the system determines whether the humidity of the main roller exceeds the standard. This device is not only low-cost but also provides effective real-time detection of roller surface humidity, preventing large-area sheet contamination caused by excessive roller surface humidity.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] Reference Figure 2 In this embodiment, the roller surface humidity monitoring device 3 is installed below the scraper 1; and the sponge roller of the roller surface humidity monitoring device 3 abuts against the roller surface of the main roller 2.

[0022] Reference Figure 1 The cylinder wall of cylinder 32 is fixed to the fixed plate 31 by cylinder bracket 33. The sliding plate 34 is connected to the piston rod of cylinder 32. The linear slide rail 35 is installed on the fixed plate, and the other linear slide rail is installed on the support plate. The two sliding plates are respectively constrained on the linear slide rail.

[0023] The two ends of the humidity sensor bracket 36 are fixed to the fixing plate 31 and the support plate 40, respectively. The humidity sensor pad 37 is fixed to the humidity sensor bracket 36, and the humidity sensor 38 is fixed to the humidity sensor pad 37. The sponge roller 39 is connected and fixed to the sliding plate 34 through the bearing seat 310. The sponge roller is connected to the bearing seat by a bearing.

[0024] The working principle of this embodiment:

[0025] During operation, cylinder 32 pushes sliding plate 34, which in turn drives sponge roller 39 to extend forward and closely fit against main roller 2. Sponge roller 39 rotates synchronously under the drive of main roller 2, continuously absorbing moisture from the roller surface. After a certain period of time, sponge roller 39 retracts under the drive of cylinder 32, briefly contacts humidity sensor 38, and then extends again, repeating this action. Humidity sensor pad 37 is made of non-metallic nylon to prevent humidity sensor 38 from contacting metal and affecting the detection results. Humidity sensor 38 detects the humidity of sponge roller 39 and sends a signal to PLC for processing. When the humidity reaches a certain value, an alarm is triggered to determine that the humidity of main roller 2 exceeds the standard.

[0026] Similarly, improvements can be made to this example by connecting the sponge roller to the support plate and the fixed plate with bearings; using a cylinder to drive the humidity sensor bracket to extend forward and periodically contact the sponge roller to detect the humidity of the sponge roller and determine whether the humidity of the roller surface exceeds the standard.

[0027] This embodiment uses a highly absorbent sponge roller as the medium for detecting roller surface humidity, which solves the problem of high difficulty or cost in detecting roller surface humidity in other methods. A cylinder is used to drive the sponge roller to retract at regular intervals to contact the humidity sensor, ensuring that the sponge roller is either rotating at low speed or stationary when in contact with the sensor, thus preventing damage to the sensor.

[0028] It should be noted that the above description is merely a preferred application example of this utility model and is not intended to limit the scope of protection of this utility model. All technical solutions employing equivalent substitutions or equivalent transformations are within the scope of protection of this utility model.
