Abstract
The utility model discloses a sleeved shaft cylinder type lithium ion battery diaphragm cutting device which comprises a sleeve body whose surface is provided with a groove which is used for the engagement with a cutter body. When in use, the sleeved shaft cylinder type lithium ion battery diaphragm cutting device can prevent the diaphragm from damaging without generating the crumb, which improves the product quality and can be widely applied in the field.
Description
Technical field
The utility model relates to a kind of cutting means, especially relates to a kind of cylindrical lithium ion battery barrier film cutting means that is used for
Background technology
In the production process of cylindrical lithium ion battery,, need cut barrier film according to technological requirement.At present, have following several problems when cutting barrier film: 1, the frock surface of using now is softer, is easy to occur uneven.Can produce chip when 2, cutting barrier film, when chip falls on the barrier film, can cause the potential safety hazard of battery.3, the operation that cuts barrier film difficulty has influenced production efficiency greatly.Therefore, in order to guarantee the quality of barrier film, avoiding the potential safety hazard of battery and enhance productivity, all the time, is the emphasis that this area need develop and develop.
The utility model content
The purpose of this utility model is above-mentioned existing by the deficiency that exists in the technology in order to solve just, provides one
Kind makes barrier film injury-free in cutting, and no chip produces, thereby avoids a kind of cylindrical lithium ion battery barrier film cutting means of potential safety hazard
The utility model is achieved by following technical proposals: a kind of axle sleeve type cylindrical lithium ion battery barrier film cutting means, comprise body, and the surface of described body is provided with groove, and described groove is used for agreeing with mutually with cutter hub.
Described body is the hollow cylinder shape.
Described groove is equidistant setting.
Described groove is set to 1-8.
The wide 0.5-2mm of described groove, dark 1-4mm.
Described body is made by nonmetallic materials.
The beneficial effects of the utility model are:
Outer surface at the axle sleeve type cutting means is provided with groove, and the channel region that can be easily designs on the axle sleeve cuts barrier film, has promoted production efficiency greatly.Operation also can not damage the surface of axle sleeve like this, has promoted the service life of frock.Avoid barrier film to cut the chip that produces in the process simultaneously, guaranteed the quality that cuts of barrier film, improved the safety and the performance of battery.This barrier film cuts the production that the axle sleeve frock is applicable to all cylindrical lithium ion batteries.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the sectional structure schematic diagram of Fig. 1.
Reference numeral: 1 cutter hub, 2 barrier films, 3 bodies, 4 grooves
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, axle sleeve type cylindrical lithium ion battery barrier film cutting means comprises body 3, and described body 3 is made by the nonmetallic materials with certain degree of hardness, make it more durable, as nylon, PP etc., its body 3 is the hollow cylinder shape, so that be installed on the barrier film frame, described on the outer surface vertical direction of body 3 the equidistant groove 4 that is provided with, described groove 4 can be set to 1-8 as required, and perhaps more, present embodiment is set to 4; The groove width of its groove 4 can be 0.5-2mm, and groove depth can be 1-4mm, as required, the present embodiment groove width is 1mm, and groove depth is 2mm, and the setting of groove 4 is in use, cutter hub 1 is aimed at its notch position downwards, will be cut around the barrier film on the body 32.By using this axle sleeve type cylindrical lithium ion battery barrier film cutting means, the channel region that can be easily designs on the axle sleeve cuts barrier film.
