Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to a roller changing trolley for a lithium battery coating machine. Background Art
[0002] The manufacturing process of power lithium batteries and energy storage battery electrodes is to mix lithium battery powder with solvent, produce slurry through a mixer or pulping machine, and send it to the mixing transfer tank for temporary storage through the slurry conveying system. When the liquid level in the buffer tank or material tank is insufficient, the slurry is transported from the transfer tank slurry conveying system. The slurry in the buffer tank or material tank is coated on the current collector to form a large roll.
[0003] The front and back coating / traction rubber rollers of the gravure (coating) equipment need to be replaced with new rollers when the continuous production meters reach the preset life. Due to the limited replacement space, the replacement trolley cannot assist in the upper and lower roller replacement in this area during the disassembly process. Manual transportation is required. The weight of the roller is more than 35kg, and the space is limited for transportation, which may cause it to fall and cause safety accidents.
[0004] The replacement of existing lithium battery gravure printing or coating rubber rollers is a limited space operation and is carried by manpower. The roller weighs 35kg and is easily dropped due to limited space, causing safety accidents. Utility Model Content
[0005] The utility model aims to solve the problem that the replacement of the existing lithium battery gravure printing or coating rubber roller is a limited space operation and is carried by manpower. The roller weighs 35kg and is easily dropped due to limited space and causes safety accidents.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A roller changing trolley for a lithium battery coating machine, characterized in that it comprises a trolley body, a group of mounting posts symmetrically arranged at both ends of the front surface of the trolley body, and a telescopic arm slidably arranged along the length direction of the mounting posts, wherein the bottom surface of the telescopic arm is provided with a mounting groove corresponding to the mounting post, and the mounting groove is slidably arranged on the mounting post;
[0008] A limiting guide groove is arranged in the middle of the upper surface of the mounting column along the length direction, and the limiting guide groove does not pass through the front end surface of the mounting column. A limiting pin is slidably arranged on the limiting guide groove, and the limiting pin is detachably connected to the rear part of the top surface in the mounting groove of the telescopic arm.
[0009] A further improvement is that a connecting plate is provided on the upper part of the trolley body.
[0010] A further improvement is that: support columns are provided at both ends of the connection plate extending forward, and the installation columns are fixedly connected to the front end surfaces of the support columns.
[0011] A further improvement is that the outer surfaces of the telescopic arm and the mounting column are provided with Teflon coating.
[0012] A further improvement is that two groups of side guide grooves are symmetrically arranged on both sides of the installation column.
[0013] A further improvement is that two groups of guide blocks adapted to the side guide grooves are symmetrically arranged on both sides of the inner wall of the telescopic arm of the telescopic arm, and the guide blocks are slidably arranged on the side guide grooves.
[0014] A further improvement is that: a limit pin threaded hole is formed through the limit pin, a telescopic arm threaded hole corresponding to the limit pin threaded hole is formed at the rear end of the telescopic arm, and the telescopic arm threaded hole passes through the mounting groove.
[0015] A further improvement is that the telescopic arm and the limit pin are detachably connected and fixed by screws that cooperate with the threaded holes of the telescopic arm and the threaded holes of the limit pin.
[0016] Compared with the existing technology, the above technical solution has the following beneficial effects:

DETAILED DESCRIPTION
[0030] See also Figure 1-Figure 10 As shown, the technical solution adopted in this specific embodiment is: a roller changing trolley for a lithium battery coating machine, comprising a trolley body 1, a group of mounting columns 3 symmetrically arranged at both ends of the front surface of the trolley body 1, and a telescopic arm 5 slidably arranged along the length direction of the mounting column 3, and the bottom surface of the telescopic arm 5 is provided with a mounting groove 51 corresponding to the mounting column 3, and the mounting groove 51 is slidably arranged on the mounting column 3;
[0031] A limiting guide groove 31 is arranged in the middle part of the upper surface of the mounting column 3 along the length direction, and the limiting guide groove 31 does not penetrate the front end surface of the mounting column 3. A limiting pin 4 is slidably arranged on the limiting guide groove 31, and the limiting pin 4 is detachably connected to the rear part of the top surface inside the mounting groove 51 of the telescopic arm 5.
[0032] Wherein, a connecting plate 2 is arranged on the upper part of the trolley body 1 .
[0033] Wherein, support columns 21 are extended forwardly from both ends of the connecting plate 2 , and the mounting column 3 is fixedly connected to the front end surface of the support column 21 .
[0034] Wherein, the outer surfaces of the telescopic arm 5 and the mounting column 3 are provided with Teflon coating.
[0035] Wherein, two groups of side guide grooves 32 are symmetrically arranged on both sides of the installation column 3.
[0036] Wherein, two groups of guide blocks 52 adapted to the side guide grooves 32 are symmetrically arranged on both sides of the inner wall of the telescopic arm 5 , and the guide blocks 52 are slidably arranged on the side guide grooves 32 .
[0037] The limit pin 4 is provided with a limit pin threaded hole 41 , and the rear end of the telescopic arm 5 is provided with a telescopic arm threaded hole 53 corresponding to the limit pin threaded hole 41 , and the telescopic arm threaded hole 53 passes through the mounting slot 51 .

[0039] The working principle of the utility model is as follows: when in use, the old roller can be removed by retracting the telescopic arm in a limited space area and entering the replacement area to adjust the position of the rubber roller to be replaced. The telescopic arm is extended to fork up the two arms for replacing the rubber roller and then retracted for transportation. The installation of the new roller is consistent with the method of removing the old roller; specifically, when the main body of the trolley enters the rubber roller replacement area, the telescopic arm is in a retracted state, and the limit pin is fixed to the rear end of the installation slot of the telescopic arm by screws; after the roller replacement area is adjusted, the telescopic arm is extended along the guide slot, forked into the rubber roller, and then the telescopic arm is retracted again. During this period, the limit pin serves as a limit to prevent the telescopic arm from excessively extending and retracting and falling off the installation column. Multiple guide slots ensure stable extension and retraction, and the metal surface is plated with Teflon to reduce friction during extension and retraction.
[0040] The above shows and describes the basic principle and main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
