Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained by combining the specific embodiments.

As shown in fig. 1-3, a battery pole piece cold pressing device, including chassis 1, the upper end of chassis 1 is rotated and is connected with a pair of cold compression roller 2, it has coating pole piece 3 to roll between the cold compression roller 2, bearing platform 4 is installed on the top of chassis 1, be connected with support frame 5 on the bearing platform 4, be equipped with guide arm 6 on the support frame 5, swivelling joint has threaded rod 7 on the support frame 5, sliding connection has two sets of guide way one 8 on the guide arm 6, and is two sets of guide way one 8 is drawn in or is kept away from back on the back in the opposite directions along guide arm 6 by the drive of threaded rod 7.

In this embodiment, the upper end of chassis 1 is equipped with spout 9, sliding connection has live-rollers 10 in spout 9, the inboard that the both ends of live-rollers 10 just are located chassis 1 is installed and is propped platform 11, the both sides of propping platform 11 are connected with guide way two 12, the both ends of live-rollers 10 just are located chassis 1's the outside and are connected with a supporting bench 13, a cylinder 14 is installed to the bottom side of supporting bench 13, the end of cylinder 14 is installed on chassis 1, live-rollers 10 carries out power transmission through belt pulley mechanism 15.
