Abstract
The invention discloses an intermittent type spreading device used for spreading a pole piece to be spread, comprising a bracket, a stander, a back roll, a receiving roll and a discharging roll. The two ends of the back roll, the receiving roll and the discharging roll are respectively rotatably connected to the bracket. The pole piece is coated on the back roll. The two ends of the pole piece arerespectively wrapped on the receiving roll and the discharging roll. The central axis of a spreading roll is on a same plane with the central axis of the back roll. The bracket can move horizontallyalong the stander. The spreading device further comprises a press roll which can rotate around the axis thereof. The two ends of the press roll are respectively fixed with the stander. The distance between the press roll and the back roll is less than the thickness of the pole piece. The pole piece is coated on the back roll and the press roll is tightly contacted with the back roll, so the friction force between the pole piece and the back roll is enhanced. The pole piece and the back roll will not slide during spreading, so the length precision for intermittent spreading is promoted.

The explanation of Figure of description critical piece
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the object of the invention is described further.
The specific embodiment
As shown in Figure 1, intermittent type coating device of the present invention proposes an embodiment.
Described intermittent type coating device is used for applied pole piece 1 is coated with, this intermittent type coating device comprises: support 7, frame 8, back flow roll 2, material receiving roller 4 and emptying roller 3, described back flow roll 2, the two ends of material receiving roller 4 and emptying roller 3 are rotationally connected with described support 7 respectively, described pole piece 1 part is coated on described back flow roll 2, the two ends of this pole piece 1 are wound on respectively on material receiving roller 4 and the emptying roller 3, the central axis of the central shaft of described applicator roll 6 and described back flow roll 2 is in same horizontal plane, described support 7 can move horizontally along described frame 8, wherein, described apparatus for coating also comprises pressure roller 5, the two ends of this pressure roller 5 are fixed with described support 7 respectively, and this pressure roller 5 can rotate around its axle, and the spacing between described pressure roller 5 and the back flow roll 2 is less than the thickness of described pole piece 1.
Specifically, when described intermittent type coating device was coated with, described frame 8 levels were moved to the left described support 7 in the drive control device drives lower edge, and make the pole piece 1 on the back flow roll that is coated on 2 contact with described coating roll 6.Described pole piece 1 under material receiving roller 4 drives, thereby described pole piece is moved along the F direction, thereby the coating on the described coating roll 6 is coated on the described pole piece 1.
When needs stay when white, described support 7 levels are moved right, described pole piece 1 and coating roll 6 become released state by contact condition.Described driving control device adopts prior art.
Because described intermittent type coating device is by being provided with rotating pressure roller 5 at described support 7, when between described pressure roller 5 and back flow roll 2, pole piece 1 being set, described pressure roller 5 exerts pressure for described pole piece 1, make the frictional force between described pole piece 1 and the described back flow roll 2 increase, when avoiding being coated with, cause because of tension force size on the described pole piece 1 changes that frictional force reduces to slide between described pole piece 1 and the described back flow roll 2, therefore can improve the length precision and the coating quality of coating at interval.
In the above-described embodiments, the face of the central shaft of the central shaft of described pressure roller 5 and described back flow roll 2 formation is vertical with horizontal plane.Described emptying roller 3 and material receiving roller 4 lay respectively at described back flow roll 2 homonymies, vertical range is less than emptying roller 3 and back flow roll 4 radius sums between the central shaft of the central shaft of this emptying roller 3 and described back flow roll 2, the cornerite that can make described pole piece 1 coat described back flow roll 2 increases, the frictional force of pole piece 1 and back flow roll 2 can be increased, and then the length precision and the coating quality of coating at interval can be further improved.Described back flow roll 2 is a rubber roll, and described applicator roll 6 is a steel rider.Described pressure roller 5 is a rubber roll, and the frictional force of 1 of described rubber roll and pole piece is increased.
