Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator coating technology, and in particular to a quick-change scraper flipping mechanism. 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 process of coating lithium battery separators, separator coating machines are often used. The coating rollers of the coating machine are often equipped with scrapers on both sides. The coating adhesive is scraped by the scrapers. However, the coating scrapers often need to be replaced. Traditional scrapers are often fixed by multiple fixed parts, which makes the scraper replacement time long and reduces the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-change scraper flipping mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-changeable scraper flipping mechanism includes a scraper box, on which scrapers are installed in scraper slots symmetrically opened on the upper and lower sides. Flipping limiting plates for resisting the scrapers are provided on the upper and lower end surfaces of the scraper box. The flipping limiting plates are rotatably mounted on the side plates on both sides of the scraper box. The side plate is provided with rotating seats at both the upper and lower ends. A rotating rod is provided between the rotating seats symmetrically located on the same horizontal line. The flip-limit plate is rotatably mounted on the rotating rod. A limit head is provided at one end of the flip-limit plate. The limit head is used to abut against the scraper installed on the scraper slot. A rotating hole is opened in the middle of the flip-limit plate for rotatably engaging with the rotating rod.

[0006] In addition, in a preferred structure, multiple limiting units are arranged laterally at both the upper and lower ends of the scraper box. The limiting units are used to abut against the outer surface of the flip-up limiting plate. Support units are symmetrically arranged on the other side of the scraper box away from where the scraper is installed. The support units are displaced by a drive unit set on the frame on which the scraper box is installed.

[0007] In addition, a preferred structure is that the limiting unit includes a mounting frame, a movable sleeve is vertically provided on the top of the mounting frame, and a telescopic abutment is vertically slidably fitted inside the movable sleeve, with the bottom end of the telescopic abutment used to abut against the outer surface of the flip-limiting plate.

[0008] In addition, a preferred structure is that a spring is fitted on the outside of the movable sleeve, with one end of the spring abutting against the top frame of the mounting bracket and the other end of the spring abutting against the telescopic abutment.

[0009] Furthermore, in a preferred configuration, the support unit includes a support plate, on one side surface of the support plate, support rollers are symmetrically and rotatably arranged, the support rollers are arranged in the gap between the flip-limit plate and the scraper box, the support rollers are used to abut against the inner surface of the flip-limit plate, and mounting feet are provided at the bottom of the other side surface of the support plate away from the support rollers, the mounting feet are mounted on the drive unit.

[0010] In addition, a preferred structure is that the drive unit includes a slide rail and a cylinder. Both the slide rail and the cylinder are mounted on the frame of the diaphragm coating machine for mounting the scraper box. A mounting slider is slidably fitted on the slide rail. The mounting foot is mounted on the mounting slider. One side wall of the mounting slider is assembled and connected to the piston rod at the output end of the cylinder.

[0011] The beneficial effects of this utility model are as follows: Through the set flip-limit plate structure, when the scraper needs to be replaced, the support unit can be controlled to exit by the drive unit, and the limit unit can automatically push the flip-limit plate open, so that the limit head is disengaged from the scraper. The operator does not need to tighten multiple bolts or other complex fasteners, and can directly take out or put in the scraper slot. This process is simple to operate and quick. This flip mechanism greatly shortens the downtime required for scraper replacement and effectively improves the efficiency of scraper replacement. Attached Figure Description

[0014] 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.

[0015] Reference Figure 1-8 A quick-change scraper flipping mechanism includes a scraper box 1. Scrapers 2 are installed in scraper slots 11 symmetrically opened on the upper and lower sides of the scraper box 1. Flipping limiting plates 4 for holding the scrapers 2 are provided on the upper and lower surfaces of the scraper box 1. The flipping limiting plates 4 are rotatably mounted on the side plates 3 on both sides of the scraper box 1. Rotating seats 8 are provided at the upper and lower ends of the side plates 3. Rotating rods 9 are provided between the symmetrical rotating seats 8 on the same horizontal line. The flipping limiting plates 4 are rotatably mounted on the rotating rods 9. A limiting head 41 is provided at one end of the flipping limiting plates 4. The limiting head 41 is used to hold the scrapers 2 installed in the scraper slots 11. A rotating hole 42 is opened in the middle of the flipping limiting plates 4 for rotating and engaging with the rotating rods 9. By holding the scrapers 2 with the flipping limiting plates 4, the quick replacement of the scrapers 2 can be achieved.

[0016] In addition, multiple limiting units 5 are arranged horizontally at both the upper and lower ends of the scraper box 1. The limiting units 5 are used to abut against the outer surface of the flip-limiting plate 4. Supporting units 6 are symmetrically arranged on the other side of the scraper box 1 away from the scraper 2. The supporting units 6 are displaced by the driving unit 7 set on the frame on which the scraper box 1 is installed. The supporting units 6 can make the flip-limiting plate 4 abut against the scraper.

[0017] Furthermore, the limiting unit 5 includes a mounting frame 51, with a movable sleeve 52 vertically mounted on the top of the mounting frame 51. A telescopic abutment 53 is vertically slidably fitted inside the movable sleeve 52. The bottom end of the telescopic abutment 53 is used to abut against the outer surface of the flip-limiting plate 4. A spring 54 is fitted on the outside of the movable sleeve 52. One end of the spring 54 abuts against the top of the mounting frame 51, and the other end of the spring 54 abuts against the telescopic abutment 53. The telescopic abutment 53 is used to abut against the flip-limiting plate 4 to achieve rapid reset.

[0018] Meanwhile, the support unit 6 includes a support plate 62. Support rollers 63 are symmetrically and rotatably arranged on one side surface of the support plate 62. The support rollers 63 are located in the gap between the flip-up limiting plate 4 and the scraper box 1. The support rollers 63 are used to abut against the inner surface of the flip-up limiting plate 4. The bottom of the other side surface of the support plate 62 away from the support rollers 63 is provided with mounting feet 61. The mounting feet 61 are mounted on the drive unit 7. The drive unit 7 includes a slide rail 71 and a cylinder 73. The slide rail 71 and the cylinder 73 are both set on the frame of the diaphragm coating machine used to install the scraper box 1. The mounting slider 72 is slidably fitted on the slide rail 71. The mounting feet 61 are mounted on the mounting slider 72. One side wall of the mounting slider 72 is assembled and connected to the piston rod at the output end of the cylinder 73. The cylinder 73 is used to push the support unit 6 to move.

[0019] In this embodiment, when it is necessary to quickly replace the scraper 2 on the scraper box 1, the cylinders 73 on both sides are driven to retract their piston rods simultaneously, and the mounting slider 72 slides on the slide rail 71, thereby driving the support unit 6 to move, so that the support roller 63 separates from the flip limit plate 4. The support roller 63 no longer supports the flip limit plate 4. At this time, after the support roller 63 no longer supports the flip limit plate 4, the spring 54 of the limit unit 5 can release its elastic potential energy to reset, thereby realizing that the telescopic abutment 53 extends from the movable sleeve 52. The telescopic abutment 53 can press the flip limit plate 4, so that the flip limit plate 4 is centered on the rotating rod 9, so that the limit head 41 no longer supports the scraper 2, and the scraper 2 can be quickly separated from the scraper slot 11, thereby realizing the quick replacement and installation of the scraper 2. When installing the scraper 2, it is only necessary to re-snap the limit block 21 of the scraper 2 back into the scraper slot 11, and the support unit 6 re-supports the flip limit plate 4.

[0020] In this invention, the flip-limit plate 4 structure allows the support unit 6 to be disengaged via the drive unit 7 when the scraper 2 needs to be replaced. The limit plate 5 automatically pushes the flip-limit plate 4 open, causing the limit head 41 to disengage from the scraper 2. The operator can directly remove or insert the scraper 2 from the scraper slot 11 without having to tighten multiple bolts or other complex fasteners. This process is simple and quick. This flip mechanism greatly reduces the downtime required for scraper replacement and effectively improves the efficiency of scraper replacement.

[0021] 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.
