Description

Technical Field

[0001] This utility model relates to the technical field of battery separator production equipment, specifically to a scraper rod adjustment mechanism. Background Technology

[0002] The extraction process for lithium-ion battery separators involves washing away the pore-filling agent from the base film to create micropores. These micropores allow lithium ions to pass freely while also providing insulation. After coating, during the extraction process, the coated film exiting one extraction tank carries a significant amount of extractant as it enters another. Therefore, before entering the next extraction tank, excess extractant on the coated film needs to be removed using a scraper.

[0003] To better remove excess extract, the scraper bar needs to cover the entire area of ​​the coating film. Currently, the scraper bar position is mainly adjusted using an eccentric flange, but this operation is demanding, the horizontal position of the scraper bar is inconvenient to adjust, and its working range is limited to a local area of ​​the coating film, resulting in incomplete removal of extract, especially for large areas or irregularly shaped coating layers. There have been attempts to expand the coverage area by increasing the number of scraper bars, but this increases the complexity and cost of the equipment.

[0004] Therefore, there is an urgent need for a device that can flexibly adjust the horizontal position of the scraper to improve removal efficiency and adapt to diverse production needs. Utility Model Content

[0005] This application provides a scraper rod adjustment mechanism, which solves the above problems. The horizontal position adjustment of the scraper rod is mainly achieved by the translation of the translation block on the base.

[0006] This application provides a scraper adjustment mechanism, including:

[0007] The base is used to fix the extraction tank wall panel. The entire adjustment mechanism is based on the base. Many components are quite heavy, so the stability of the base is particularly important.

[0008] A translation block is slidably mounted on the base, and the translation block is provided with a mounting part for mounting the scraper rod.

[0009] In some embodiments, in order for the translation block to be slidably mounted on the base, the base is provided with a groove, and the size of the groove matches the size of the translation block.

[0010] In some embodiments, in order to facilitate the movement of the translation block within the groove under force, a push rod mechanism is provided at each end of the base, and the tops of the two push rod mechanisms respectively abut against the two ends of the translation block. The push rod mechanism is a device that can force the object being abutted to move by moving its tops.

[0011] In some embodiments, in order to control costs, facilitate processing, and make adjustment convenient, the aforementioned push rod mechanism is a bolt push rod mechanism.

[0012] In some embodiments, to facilitate observation of how far the translation block has translated in the horizontal direction of the base, at least one end of the base is provided with a scale corresponding to the translation block.

[0013] In some embodiments, in order for the entire adjustment mechanism to both translate and rotate the scraper bar, the mounting portion further includes:

[0014] A sleeve, wherein the sleeve is provided with a keyway that matches the scraper rod for fixing and installing the scraper rod;

[0015] The driving sub-unit is used to drive the aforementioned rod sleeve, allowing it to rotate on the aforementioned base.

[0016] In some embodiments, in order to achieve advantages such as compact structure, easy installation, and good heat dissipation, the drive sub-unit generally includes a worm gear and a worm that mesh with each other, and the sleeve is embedded inside and fixed to the worm gear.

[0017] In some embodiments, for ease of operation, the drive sub-part is provided with a handle, which is connected to the worm gear.

[0018] In some embodiments, in order to facilitate fixing the position of the scraper rod, a keyway is provided on the inner side wall of the rod sleeve for connecting the scraper rod.

[0019] In some embodiments, in order for the scraper bar to slide a certain distance in the horizontal direction, a space is needed to allow the scraper bar to move horizontally, and the base is provided with an oblong hole for the scraper bar to pass through.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are:

[0021] This invention achieves the translation of the scraper rod by loosening the bolts on the pressure plate, rotating the bolt pusher to move the translation block forward or backward within the groove on the base, and tightening the bolts on the pressure plate to fix the position of the translation block when it reaches the process position. The drive unit is fixed to the translation block by bolts. The shaft of the scraper rod passes through the oblong hole of the base, the mating round hole of the translation block, and the rod sleeve in sequence, and is fixed to the keyway on the rod sleeve by a flat key. The angle of the scraper rod is changed by rotating the handle on the drive unit, thus realizing the rotation of the scraper rod. Attached Figure Description

[0029] Please refer to Figure 1-4 This application provides a scraper bar adjustment mechanism, including:

[0030] Base 1, used for fixing to the wall panel of the extraction tank;

[0031] The translation block 2 is slidably mounted on the base 1, and the translation block 2 is provided with a mounting part for mounting the scraper rod 11.

[0032] In order to facilitate the horizontal sliding of the translation block 2 within the base 1, the base 1 is provided with a sliding groove that matches the size of the translation block 2, and the translation block 2 is also provided with a mounting part for mounting the scraper rod.

[0033] In this embodiment, the translation of the scraper rod 11 is achieved by the horizontal movement of the translation block 2 within the groove on the base 1.

[0034] Please refer to Figure 1-4 As an optional embodiment of this application, the base 1 is fixedly installed in the flange of the extraction tank wall plate, and the lower part of the base 1 is provided with a boss, and the groove in the boss is reinforced with a sealing ring, the function of which is to prevent dichloromethane gas leakage from causing incalculable losses to production and daily life.

[0035] Please refer to Figure 1-4 As an optional embodiment of this application, a push rod mechanism is provided at each end of the base 1, with the push rod heads facing each other and abutting against the two ends of the translation block 2. The push rod mechanism is a bolt push rod mechanism, which consists of a bolt push rod 6 and a nut 5 fixed on the base 1. The nut 5 is fixedly installed on the base 1 and serves to fix the bolt push rod 6. Rotating the bolt push rod 6 causes the upper push head to move, forcing the translation block 2 to move to the process position. Then, tightening the fixing screws on the pressure plate 3 completes the horizontal movement of the scraper rod 11. The aforementioned translation block 2 is fixed in the sliding groove on the upper end face of the aforementioned base 1 by the aforementioned pressure plate 3 and fixing bolts. When the aforementioned translation block 2 needs to be adjusted horizontally, first loosen the fixing bolts on the aforementioned pressure plate 3, then rotate the aforementioned bolt top rod 6 to move its upper top head to force the aforementioned translation block 2 to move to the process position, and then tighten the fixing screws on the aforementioned pressure plate 3. By doing this operation, the aforementioned scraper rod 11 can be moved horizontally.

[0036] Please refer to Figure 1-4 As an optional embodiment of this application, at least one end of the base 1 is provided with a scale 7 corresponding to the translation block 2. When the bolt rod 6 is rotated to move its upper head, the translation block 2 is forced to move to the process position. During this horizontal movement, the movement distance of the horizontal block 2 can be monitored at all times through the scale 7 to achieve data monitoring. This is the significance of setting the scale 7.

[0037] Please refer to Figure 1-4 As an optional embodiment of this application, the above-mentioned mounting part includes:

[0038] The sleeve 10 is provided with a keyway, the size and depth of which match the scraper rod 11. The scraper rod 11 is fixedly installed by a flat key connection, so that the scraper rod 11 is stable and firm during operation.

[0039] The driving sub-part 4 is capable of driving the aforementioned sleeve 10, allowing the sleeve 10 to rotate on the base 1.

[0040] Please refer to Figure 1-4As an optional embodiment of this application, the drive sub-part 4 includes a worm gear and a worm shaft that mesh with each other, and the sleeve 10 is embedded inside and fixed to the worm gear. The worm gear and worm shaft have the following advantages: relatively compact structure, small space occupation, suitable for use in limited spaces; good heat exchange performance, fast heat dissipation, suitable for long-term high-load operation; lightweight and easy to maintain and repair.

[0041] Please refer to Figure 1-4 As an optional solution in this application embodiment, in order to facilitate driving the worm gear and worm, a handle 9 is provided on the side of the drive sub-part 4, and the surface of the handle 9 is covered with a threaded rubber layer to increase friction and play an anti-slip role.

[0042] Please refer to Figure 1-4 As an optional embodiment of this application, the base 1 has an oblong hole 12 for the scraper rod 11 to pass through. The shaft of the scraper rod 11 passes sequentially through the oblong hole 12 of the base 1, the mating hole of the horizontal block 2, and the mating hole of the drive sub-part 4, and is fixed to the keyway on the sleeve 10 by a flat key. In order for the scraper rod 11 to slide a certain distance in the horizontal direction, a space is needed to allow the scraper rod 11 to move horizontally. The base 1 has an oblong hole 12 for the scraper rod 11 to pass through, instead of a mating hole, so that the space required for the horizontal movement of the scraper rod 11 can be achieved.

[0043] Please refer to Figure 1-4 In an optional embodiment of the present application, by rotating the handle 9, the worm gear and worm shaft mesh with each other, driving the sleeve 10 to rotate at different angles. The scraper rod 11 is fixed to the sleeve 10 via a keyway, thus causing the scraper rod 11 to rotate at different angles, thereby completing the rotation of the scraper rod 11. In actual production, when the scraper rod needs to rotate to remove residual extract from the membrane surface, the handle 9 can be rotated, and the worm gear and worm shaft inside the drive unit 4 mesh with each other, driving the sleeve 10 to rotate at different angles. Since the scraper rod 11 is fixed to the sleeve 10 via a keyway, the scraper rod 11 rotates accordingly. This action relationship allows the scraper rod to rotate at different angular positions.
