In the technical scheme, 4-10 thread grooves are respectively distributed on two sides of the flattening roller.

In the technical scheme, the width of the thread groove is 2mm-5mm.

In the technical scheme, the depth of the thread groove is 0.5mm-1mm.

In the above technical scheme, the first press roll and the flattening roll are made of aluminum.

The deviation correcting device with the flattening roller in the technical scheme further comprises a deviation correcting mechanism, wherein the deviation correcting mechanism is arranged on the vertical frame and is positioned below the edge-most compression roller, and the deviation correcting mechanism can limit the foil; the deviation correcting mechanism comprises a mounting block and two limiting blocks, the mounting block is mounted on the vertical frame, and the two limiting blocks are slidably mounted on the mounting block; the deviation correcting device with the flattening roller further comprises a second press roller, the second press roller is cylindrical, and the second press roller is rotatably arranged below the deviation correcting mechanism.

The beneficial effects of the utility model are as follows: according to the utility model, the flattening roller is arranged to be high in the middle and low in the two sides, so that the pole piece has tension to the two sides in the coating process, and the wrinkling phenomenon of the middle pole lug is balanced.

Detailed Description

The utility model will be further described with reference to the drawings and examples.

The conception, specific structure, and technical effects produced by the present utility model will be clearly and completely described below with reference to the embodiments and the drawings to fully understand the objects, features, and effects of the present utility model. It is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present utility model based on the embodiments of the present utility model. In addition, all the coupling/connection relationships referred to in the patent are not direct connection of the single-finger members, but rather, it means that a better coupling structure can be formed by adding or subtracting coupling aids depending on the specific implementation. The technical features in the utility model can be interactively combined on the premise of no contradiction and conflict.

Referring to fig. 1, as shown in the drawing, the present utility model provides a deviation correcting device with flattening rollers, which comprises a stand 1, two first press rollers 2 and two flattening rollers 3.

Be equipped with four installation positions on the grudging post 1, first compression roller 2 and the horizontal rotation of nip roll 3 are installed in the installation position of grudging post 1, and first compression roller 2 and nip roll 3 interval arrangement, first compression roller 2 is the roller, and nip roll 3 is the centre diameter and is greater than the circular roll of both sides diameter, and reduces gradually from centre to both sides diameter, nip roll 3 is opened respectively along centre to both sides has the screw thread groove that the rotation direction is opposite.

According to the utility model, the foil is transported by arranging the two first press rolls 2 and the two flattening rolls 3, in the embodiment, the pole pieces are transported by taking the example of pole piece transportation, the pole lugs pass through the upper parts of the flattening rolls 3, then pass through the lower parts of the first press rolls 2 after passing through the upper parts of the next flattening rolls 3, pass through the lower parts of the next first press rolls 2, the middle of the flattening rolls 3 is high, the two sides of the flattening rolls 3 are low, and the tension of one pole piece to two sides can be caused in the coating process by the thread grooves on the flattening rolls 3, so that the middle pole lugs are balanced, and the phenomenon of wrinkling is avoided.
