And the product has simple structure, good stability, simple processing flow, few changed parts, short processing time and low cost.
Description
Technical Field
The utility model relates to a copper foil manufacture equipment technical field, concretely relates to a transmission deflector roll for carrying out the rolling to the copper foil.
Background
With the development of science and technology, lithium electrolytic copper foil used for power batteries is required to be thinner and thinner, from the original 12 micrometers, 9 micrometers and 8 micrometers to the current 5 micrometers, the copper foil with the thickness of 4 micrometers is about to occupy the whole industry market in the near future, so that the precision requirement on copper foil manufacturing equipment is higher and higher, and partial equipment or parts are gradually replaced or need to be improved. The transmission guide roller is a large factor influencing the quality of copper foil products, the thinner the copper foil is, the more easily the copper foil is wrinkled, and in order to improve the yield, the linear speed of production equipment can be faster. Because the width of the product is more than 720 plus 1550MM, the winding speed is high, air extrusion is incomplete or slight impurities and dust fall on the guide roller, the quality is poor, the surface quality problems of the copper foil are caused, such as air bubbles, impurities, wrinkles and other defects, and the product can be scrapped. At present, the solution to the above problem is to add a press roll, and press the copper foil at the tangent position of the transmission guide roller through the press roll to extrude bubbles, flatten wrinkles and the like. However, the pressing roller is not only not effective enough, for example, the air bubbles cannot be completely extruded, but also the structure is more complicated, the cost is higher, and the application is inconvenient.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to the shortcoming that prior art exists, provide a simple structure, use convenient, can solve the improvement structure copper foil transmission deflector roll of bubble, impurity influence better.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an improvement structure copper foil transmission deflector roll, is including the roll body, and the outmost roller top layer for the metal material of roll body, its characterized in that: the surface on roller top layer has several notches set along the circumference of roller body, and the notches penetrate into the roller top layer and do not penetrate through the roller top layer and form one circular notch around the surface of roller top layer. And polishing and grinding the surface of the cutter groove by using a special grinding machine after the cutter groove opening is opened. When the copper foil is rolled, the stress generated in the rolling process can be released through each knife slot so as to avoid generating bubbles.
Preferably, the notch of the cutter is a square groove, the corner positions of the tops of the side walls on the two sides of the notch are both set to be chamfer structures, and the chamfer angle is 45 degrees, so that the copper foil can be prevented from being scratched by the corner of the notch.
Preferably, the width and the depth of the notch are respectively 1 mm, and the size can better accommodate air bubbles and impurities and simultaneously has no obvious supporting effect on the copper foil.
Preferably, the distance between each of the two notches near the two ends of the roller body and the corresponding edge is 40-60 mm, and most preferably 50 mm.
Preferably, the knife gaps are uniformly arranged on the surface layer of the roller, and the spacing distance between two adjacent knife gaps is 15-25 mm, and the optimal spacing is 20 mm, so that the size can well extrude bubbles, and simultaneously, the copper foil can be well supported, and good rolling is achieved.
Further, the thickness of the roller surface layer where the bottom of the knife notch is not penetrated is smaller than the depth of the knife notch.
The utility model discloses a processing multichannel sword notch on former deflector roll surface, can hold impurity simultaneously with near bubble suction completely through the sword notch, consequently can press the copper foil more level. The device is particularly suitable for the copper foil industry, slitting equipment with thin product specification, large breadth and high speed, releases the stress in the product rolling process, and effectively avoids and solves the quality problem caused by transmission on the surface of the copper foil. And the product has simple structure, good stability, simple processing flow, few changed parts, short processing time and low cost.

In the figure, 1 is a roller body, 2 is a roller surface layer, 3 is a cutter notch, and 4 is a chamfer.
Detailed Description
In this embodiment, referring to fig. 1 and 2, the copper foil transmission guide roller with the improved structure includes a roller body 1, the outermost layer of the roller body 1 is a roller surface layer 2 made of a metal material, a plurality of cutter notches 3 are formed on the surface of the roller surface layer 2 along the circumferential direction of the roller body 1, the cutter notches 3 penetrate into the roller surface layer 2 but do not penetrate through the roller surface layer 2, and each cutter notch 3 forms a circular groove encircling the surface of the roller surface layer 2. And polishing and grinding the surface of the notch 3 by using a special grinding machine after the notch is opened. When the copper foil is rolled, the stress generated in the rolling process can be released through each cutter notch 3, so that bubbles are prevented from being generated.
The cutter notch 3 is a square groove, the top corner positions of the side walls on the two sides of the notch are all set to be chamfer 4 structures, the angle of the chamfer 4 is 45 degrees, and the copper foil can be prevented from being scratched by the corner of the notch.
The width and the degree of depth of sword notch 3 respectively are 1 millimeter, and this size can compromise the holding capacity to bubble, impurity betterly, simultaneously not obvious support effect to the copper foil again.
The distances between the two cutter notches 3 respectively close to the edges of the two ends of the roller body 1 and the corresponding edges are 40-60 mm, and the best distance is 50 mm.
The cutter notches 3 are uniformly arranged on the roller surface layer 2, the spacing distance between every two adjacent cutter notches 3 is 15-25 mm, the optimal spacing distance is 20 mm, bubbles can be well extruded by the size, and meanwhile, the copper foil can be well supported to achieve good rolling.
The thickness of the roll surface layer 2 at the bottom of the blade slot 3, which is not penetrated, is smaller than the depth of the blade slot 3, for example the depth of the blade slot is 1 mm, and the total thickness of the roll surface layer 2 is in principle smaller than 2 mm.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
