Description

Technical Field

[0001] This utility model relates to the field of lithium battery electrode production technology, specifically to a lithium battery electrode sintering roller kiln. Background Technology

[0002] The performance of lithium batteries is crucial in daily use, and the quality of the electrodes, as the core components of lithium batteries, has a vital impact on their performance. Advanced electrode manufacturing processes can not only improve the electrochemical performance of batteries but also reduce economic costs and increase battery efficiency. Among the electrode manufacturing processes, drying is particularly important. Drying the electrodes requires sintering in a roller kiln, using high-temperature heating to form a dense solid structure.

[0003] In the long-term use of existing sintering roller kilns, the rollers are prone to wear or aging due to prolonged operation at high temperatures. During the installation process, the track support is first fixed with fixing bolts or other fasteners, and then the track to be installed is placed inside the support and fixed again. As a result, the overall process of disassembling and replacing a single track is quite cumbersome and inconvenient. Utility Model Content

[0012] This utility model provides a roller kiln for sintering lithium battery electrodes, which has the following beneficial effects:

[0013] (1) By rotating the fixing bolt, the fixing bolt is disengaged from the inside of the threaded fixing groove. At this time, the roller body is disengaged from the connection between the roller and the rotating ring. The connecting arm is flipped, and the connecting arm drives the torsion spring rod to deform, thereby driving the insert block to disengage from the inside of the slot. At this time, the fixing plate is disengaged from the restriction and pulled outward. The fixing plate drives the rotating ring to disengage from the inside of the roller kiln body from the through hole. After the roller body is disengaged from the restriction, it is pulled outward. The protrusion disengages from the inside of the snap-fit ​​groove and the output shaft disengages from the inside of the mounting groove, which makes it convenient for the staff to replace and repair a single roller body.

[0014] (2) By rotating the knob, the knob rotates and drives the lead screw to rotate. The lead screw rotates and drives the cleaning scraper to move. The cleaning scraper moves along the outer wall of the positioning rod to clean the top of the base.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a lithium battery electrode sintering roller kiln includes a roller kiln body 1, a base 2 fixedly connected to the bottom end of the roller kiln body 1, a drive motor 3 fixedly connected to the outer wall of the roller kiln body 1, and a fixing mechanism 4 provided inside the roller kiln body 1. The fixing mechanism 4 includes a roller body 41, a threaded fixing groove 42 opened at the top end of the roller body 41, an installation groove 415 opened on the outer wall of the roller body 41, and a snap-fit ​​groove 416 opened on the inner wall of the installation groove 415.

[0023] The fixing mechanism 4 includes a fixing plate 43, a through hole 44 is provided on the inner wall of the roller kiln body 1, a rotating ring 45 is rotatably connected to one side of the fixing plate 43, and a slot 411 is provided on the other side of the fixing plate 43.

[0024] The movement of the fixed plate 43 can drive the rotating ring 45 to move inside the through hole 44.

[0025] Among them, the outer wall of the roller kiln body 1 is fixedly connected to a bracket 47, the outer wall of the bracket 47 is fixedly connected to a torsion spring rod 48, the outer wall of the torsion spring rod 48 is fixedly connected to a connecting arm 49, and the outer wall of the connecting arm 49 is fixedly connected to an insert block 410.

[0026] The position of the connecting arm 49 can be limited by the torsion spring rod 48 without being affected by external forces.

[0027] Among them, the drive motor 3 is fixedly connected to one end of the roller kiln body 1 with an output shaft 412, a pad 413 is fixedly connected to the outer wall of the output shaft 412, and a protrusion 414 is fixedly connected to the outer wall of the output shaft 412.

[0028] The protrusion 414 is inserted into the snap-fit ​​groove 416, thereby restricting the position of the roller 41.

[0029] The base 2 is equipped with a cleaning mechanism 5, and a positioning rod 51 is fixedly connected to the inner wall of the base 2.

[0030] The cleaning mechanism 5 can clean the impurities attached to the top of the base 2.

[0031] The outer wall of the positioning rod 51 is slidably connected to the cleaning scraper 52, and the inner wall of the base 2 is rotatably connected to the lead screw 53, which is threaded through and connected to the inside of the cleaning scraper 52.

[0032] The positioning rod 51 can restrict the movement trajectory of the cleaning scraper 52.

[0033] The base 2 has a collection groove 55 at its top and a collection box 56 at its bottom. A knob 54 is fixedly connected to one end of the lead screw 53 near the base 2.

[0034] The lead screw 53, when rotated, can drive the cleaning scraper 52 to move horizontally.

[0035] This utility model provides a roller kiln for sintering lithium battery electrodes, and its specific working principle is as follows:

[0036] During use, when cleaning of a single roller 41 is required after prolonged use, the fixing bolt 46 is rotated, disengaging from the threaded fixing groove 42. At this time, the roller 41 is disconnected from the rotating ring 45. The connecting arm 49 is flipped, causing the torsion spring rod 48 to deform, which in turn causes the insert block 410 to disengage from the slot 411. At this time, the fixing plate 43 is released from its restraint and pulled outward. The fixing plate 43 causes the rotating ring 45 to disengage from the roller kiln body 1 through the through hole 44. After the roller 41 is released from its restraint, it moves outward. Pulling the protrusion 414 disengages it from the inside of the slot 416 and the output shaft 412 disengages it from the inside of the mounting slot 415, making it easier for workers to replace and maintain individual rollers 41. When there are many impurities attached to the top of the base 2, the worker turns the knob 54. The rotation of the knob 54 drives the lead screw 53 to rotate, and the rotation of the lead screw 53 drives the cleaning scraper 52 to move. The cleaning scraper 52 moves along the outer wall of the positioning rod 51 to clean the top of the base 2. The impurities that are cleaned off enter the inside of the collection box 56 through the collection groove 55, making it easier for workers to clean them.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
