Above-mentioned novel rolling compression roller structure, along with the diameter of going on the material book of coiling increases gradually, the air-vent valve adjustment makes slip table cylinder drive compression roller structure remove gradually to the air input of slip table cylinder, guarantees that compression roller structure is invariable to the pressure of pole piece to avoid the utmost point ear to turn over the problem of rolling over, the pole piece is rolled up after passing the roller again, guarantees that the pole piece is rolled up the income piece angle of book unanimous, thereby guarantees the precision of coiling.

Description

Novel rolling compression roller structure

Technical Field

The utility model relates to the technical field of lithium battery production, in particular to a novel rolling press roller structure.

Background

The existing winding press roller mechanism utilizes an air cylinder to push a swing arm fixed on a rotating shaft, and the press roller is leaned against a material roll to work. The mechanism has the advantages that the force arm of the air cylinder can change along with the increase of the winding diameter, the larger the winding diameter is, the more obvious the swing arm changes, the thickness of the two sides of the pole piece material roll can change due to the change of the swing arm, the thickness of the pole piece material roll is uneven, and the problems of uneven winding, wrinkling of the winding and the like can be caused.

Disclosure of Invention

The utility model mainly aims to provide a novel rolling press roller structure, so as to solve the technical problems, and the novel rolling press roller structure can drive the press roller structure to move in the winding process, so that the roller surface is always tightly attached to a pole piece, and the influence caused by uneven thickness of the pole piece is adapted.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel rolling compression roller structure, including compression roller structure, mount pad, slip table cylinder and guiding axle, the slip table cylinder with the guiding axle install in on the mount pad, the slip table cylinder drive compression roller structure is followed the guiding axle removes, and the pole piece passes compression roller structure in the rolling forms the material and rolls up in the receipts material axle, compression roller structure compresses tightly the pole piece extremely the material is rolled up.

As a preferable technical scheme, the compression roller structure comprises a slipway seat, a connecting rod, a compression roller mounting seat, a roller and a compression roller, wherein the roller is arranged on the slipway seat in a rotating mode, the compression roller is arranged on the compression roller mounting seat in a rotating mode, and the compression roller mounting seat is fixedly arranged on the slipway seat through the connecting rod.

As a preferable technical scheme, the device further comprises a pressure regulating valve, wherein the pressure regulating valve is communicated with the sliding table cylinder.

The utility model has the beneficial effects that: above-mentioned novel rolling compression roller structure, along with the diameter of going on the material book of coiling increases gradually, the air-vent valve adjustment makes slip table cylinder drive compression roller structure remove gradually to the air input of slip table cylinder, guarantees that compression roller structure is invariable to the pressure of pole piece to avoid the utmost point ear to turn over the problem of rolling over, the pole piece is rolled up after passing the roller again, guarantees that the pole piece is rolled up the income piece angle of book unanimous, thereby guarantees the precision of coiling.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Please combine fig. 1, fig. 2 and fig. 3 to show, a novel rolling press roll structure, including press roll structure 4, mount pad 1, slip table cylinder 2, guiding axle 3 and air-vent valve 5, slip table cylinder 2 and guiding axle 3 are installed on mount pad 1, slip table cylinder 2 drive press roll structure 4 is along guiding axle 3 removal, pole piece a passes press roll structure 4 and rolls up in rolling material axle c and form material book b, press roll structure 4 compresses tightly pole piece a to material book b, air-vent valve 5 and slip table cylinder 2 communicate, along with pole piece a coiling, the diameter of material book b increases gradually, press roll structure 4 increases gradually the pressure of pole piece a, thereby make slip table cylinder 2's output power increase gradually, in order to keep press roll structure 4 to pole piece a's pressure invariable, air-vent valve 5 adjusts the air input of slip table cylinder 2, thereby make press roll structure 4 to pole piece a's pressure invariable, the income piece position when guaranteeing pole piece a coiling remains invariable, thereby avoid the problem that the tab turns over, press roll structure 4 can hug closely pole piece a on material book b, guarantee the quality of coiling electric core.

As shown in fig. 1, 2 and 3, the press roller structure 4 includes a slide seat 41, a connecting rod 43, a press roller mounting seat 44, a passing roller 42 and a press roller 45, the passing roller 42 is rotatably disposed on the slide seat 41, the press roller 45 is rotatably disposed on the press roller mounting seat 44, and the press roller mounting seat 44 is fixedly disposed on the slide seat 41 through the connecting rod 43.

When the novel winding press roller structure is used, firstly, the pole piece a passes through the roller 42, the end part of the pole piece a is fixed on the winding material shaft c, the sliding table cylinder 2 is driven to enable the press roller 45 to press the pole piece onto the winding material shaft c, then the winding material shaft c starts to wind, the diameter of the material roll b is gradually increased along with the winding of the pole piece a, the pressure of the press roller structure 4 on the pole piece a is gradually increased, so that the output force of the sliding table cylinder 2 is gradually increased, the pressure of the press roller structure 4 on the pole piece a is kept constant, and the pressure regulating valve 5 adjusts the air inflow of the sliding table cylinder 2, so that the pressure of the press roller structure 4 on the pole piece a is kept constant.
