[ detailed description ] embodiments

In order to make the objects, technical solutions and advantageous technical effects of the present invention more clearly understood, the present invention is further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration only and not by way of limitation.

Referring to fig. 1 to 2, the present invention provides a width adjusting device 100 for a gasket of a coating die head, which is mainly used to reduce the standby inventory of the die head 10, increase the recycling rate of the die head 10, avoid frequent replacement of the die head 10, and effectively improve the efficiency of the coating process.

The utility model discloses an in the embodiment, die head 10 is rectangle cavity form, the disconnection forms opening 11 in the middle of its long limit, on die head 10 forms open-ended both ends tip, be equipped with a spout 12 that is used for placing slider 20 respectively, slide including supplying slider 20, be equipped with the first scale 13 that is used for looking over slider 20 displacement distance between spout 12 and the die head 10 outside, this first scale 13 need be the scale interval of high accuracy, the person of facilitating the use is according to the audio-visual adjustment width of demand, other three edges at die head 10 are equipped with a plurality of screw holes 14 at the interval respectively, a screw fixation is passed through with die head 10.

In this embodiment, the sliding block 20 includes a measuring portion 21 and a width limiting portion 22, the measuring portion 21 is located in the sliding groove 12 and can slide in the sliding groove 12, the width limiting portion 22 is integrally connected with one end of the measuring portion 21 and extends out of the die head 10, in the opening 11, when the measuring portion 21 moves along the sliding groove 12, the width limiting portion 22 is driven to move in the opening 11, so as to adjust the width of the die head 10, and a second scale 23 corresponding to the first scale 13 is arranged on one side of the measuring portion 22 close to the first scale 13, so as to form a complete scale value; the width limiting part 22 is provided with a chamfer 24 at one end part far away from the measuring part 21, so that the width limiting part is convex in the middle of two sides inwards concave, thus the flowing condition of slurry in the extrusion die head 10 can be improved, the dead zone of the slurry is eliminated to a certain extent, and the coating effect at the edge of the discharge port is improved, thereby avoiding the phenomenon of edge bulging of the pole piece.
