Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator coating technology, and in particular to a liftable scraper box. Background Technology

[0002] A lithium battery separator production line refers to a series of equipment and processes used to produce lithium battery separators. The separator is a crucial component of a lithium battery; it isolates the positive and negative electrodes, preventing short circuits, while allowing lithium ions to pass through, enabling the battery to charge and discharge. The quality and performance of the separator directly affect the safety, cycle life, and energy density of the lithium battery.

[0003] In the coating process of lithium battery separators, separator coating machines are often used. The coating rollers of the coating machine are often equipped with scraper boxes on both sides. When changing coating rollers of different diameters, it is often necessary to disassemble and assemble the scraper boxes to adjust the distance and height of the scraper boxes on both sides to adapt to coating rollers of different diameters. However, the process of disassembling the scraper boxes is cumbersome and cannot achieve quick adjustment of the scraper boxes, resulting in a long replacement time. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a liftable scraper box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liftable scraper box includes a lifting unit, which is symmetrically arranged on both sides of the scraper box unit. The scraper box unit consists of a pair of scraper boxes. The lifting unit includes a driving mechanism, a guiding mechanism, and a sliding mechanism. The sliding mechanism is symmetrically arranged on the back of the scraper box and is connected to the scraper box through a connecting seat.

[0007] The sliding mechanism includes a mounting bracket, a slide rail on the mounting bracket, a slider that slides on the slide rail, a single-bar bearing on one side wall of the slider, and a guide mechanism for limiting the movement trajectory of the single-bar bearing.

[0008] In addition, a preferred structure is that one end of the connecting seat is provided with a scraper box connecting plate and the other end is provided with a slider connecting plate. The scraper box connecting plate is used to connect with the scraper box, and the slider connecting plate is used to connect with the sliding mechanism.

[0009] Furthermore, in a preferred configuration, the guiding mechanism includes a guide plate, with connecting base plates symmetrically arranged at the bottom of the guide plate, the connecting base plates being used for mounting on the driving mechanism.

[0010] In addition, a preferred structure is that each guide plate is provided with a limiting groove, and the single rod bearing is slidably fitted at the limiting groove.

[0011] Furthermore, in a preferred configuration, the drive mechanism includes a servo electric cylinder, a piston rod is provided at the top output end of the servo electric cylinder, a support plate is provided at the top end of the piston rod, and a connecting base plate is mounted on the upper surface of the support plate.

[0012] The beneficial effects of this utility model are as follows: This utility model achieves this through a lifting unit. When installing coating rollers with different diameters, the distance and height of the two sides of the scraper box can be adjusted synchronously through the lifting unit. The synchronous lifting and lowering of the two sides of the scraper box is achieved through the cooperation of the guide mechanism and the sliding mechanism. At the same time as lifting and lowering, the distance between the two sides of the scraper box can be adjusted. In this way, there is no need to manually disassemble the scraper box to change the distance and height between them to adapt to coating rollers of different diameters. The adjustable scraper box of this application is more flexible and the adjustment efficiency of the scraper box is higher. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5A liftable scraper box includes a lifting unit 02, which is symmetrically arranged on both sides of a scraper box unit 01. The scraper box unit 01 consists of a pair of scraper boxes 1. The lifting unit 02 includes a driving mechanism 3, a guiding mechanism 4, and a sliding mechanism 5. The sliding mechanism 5 is symmetrically arranged on the back of the scraper box 1 and is connected to the scraper box 1 through a connecting seat 2. The scraper boxes are symmetrically installed on both sides of the coating roller.

[0021] In addition, the sliding mechanism 5 includes a mounting bracket 53, a slide rail 52 is provided on the mounting bracket 53, a slider 51 is slidably fitted on the slide rail 52, a single rod bearing 511 is provided on one side wall of the slider 51, and a guide mechanism 4 is used to limit the movement trajectory of the single rod bearing 511. By sliding the slider 51 on the slide rail 52, the distance can be adjusted at the same time as the lifting and lowering adjustment of the two scraper boxes 1.

[0022] The connecting seat 2 has a scraper box connecting plate 21 at one end and a slider connecting plate 22 at the other end. The scraper box connecting plate 21 is used to connect with the scraper box 1, and the slider connecting plate 22 is used to connect with the sliding mechanism 5.

[0023] In addition, the guide mechanism 4 includes a guide plate 41, and a connecting base plate 42 is symmetrically arranged at the bottom of the guide plate 41. The connecting base plate 42 is used to be installed on the drive mechanism 3. Each guide plate 41 is provided with a limiting groove 411. The single rod bearing 511 is slidably fitted at the limiting groove 411. The limiting groove 411 is used to drive the single rod bearing 511 to slide.

[0024] Furthermore, the drive mechanism 3 includes a servo electric cylinder 31, a piston rod 32 is provided at the top output end of the servo electric cylinder 31, a support plate 33 is provided at the top end of the piston rod 32, and a connecting base plate 42 is installed on the upper surface of the support plate 33. The servo electric cylinder 31 is used to realize the lifting and lowering of the scraper box 1.

[0025] In this embodiment, when installing coating rollers with different diameters, the distance and height of the two scraper boxes 1 on both sides can be adjusted synchronously by the lifting unit 02. During adjustment, the piston rod 32 is extended and retracted by the servo electric cylinder 31, thereby adjusting the lifting and lowering of the support plate 33. When the support plate 33 is lifted and lowered, it drives the guide mechanism 4 to lift and lower. As the guide plate 41 is lifted and lowered, the single rod bearing 511 in the limiting slide groove 411 will change synchronously with the change of the position of the limiting slide groove 411, thereby realizing the sliding of the slider 51 on the slide rail 52, thereby realizing the synchronous lifting and lowering of the two scraper boxes 1 on both sides, and at the same time as lifting and lowering, the distance between the two scraper boxes 1 on both sides is adjusted.

[0026] In this utility model, the lifting unit 02 is used to adjust the distance and height of the two scraper boxes 1 synchronously when installing coating rollers with different diameters. The synchronous lifting of the two scraper boxes 1 is achieved through the cooperation of the guide mechanism 4 and the sliding mechanism 5. At the same time as lifting, the distance between the two scraper boxes 1 is adjusted. This eliminates the need for manual disassembly of the scraper boxes 1 to change the distance and height between them to adapt to coating rollers of different diameters. The adjustable scraper box of this application is more flexible.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
