Abstract

The utility model relates to a rolled copper foil packing box, belonging to the technical field of packing box used for rolled copper foil packing, comprising a base and a box cover matched with the base; the lower part of the base is a base platform; four base walls are formed upwards along the inner edge of the base platform; two concave positions are opened downwards from the tops of two corresponding base walls, and two baffles formed by the base walls are arranged outside the concave positions; two inner convex platforms are formed on the two inner walls of the box cover corresponding to the two base walls; two inner concave positions corresponding to the concave positions are opened downwards from the tops of the inner convex platforms; the box cover is matched with the base, and two round hole sites are formed by docking the concave position and the inner concave position. The rolled copper foil packing box has the advantages that, the safety factor of rolled copper foil packing box is enhanced; relative displacement of copper foil product in the packing box is avoided; deformation, wrinkling and other phenomenon of the rolled copper foil caused by vibration, bumpiness, box inversion and other reasons in the transport process are greatly reduced, and the quality of the product in the packing box is ensured.

Description

Web-like Copper Foil packing chest

Technical field

The utility model relates to the packing chest technical field of packing web-like Copper Foil.

Background technology

(be called for short: lithium electrolytic copper paper tinsel) be mainly used in the negative pole carrier of lithium ion battery, also be negative current collector to lithium ion battery with electrolytic copper foil.The finished product of lithium electrolytic copper paper tinsel generally becomes web-like, and the volume core is supported by paper tube, the about 100～700mm of its wide cut, and weight does not wait from several kilograms to kilograms up to a hundred.The finished copper foil of web-like is in transportation, and general employing can be placed the wood packing box transportation of number volume web-like Copper Foil

The packing chest of traditional transportation web-like Copper Foil is made of base 1 and the case lid 2 that buckles thereon, offers the groove support 100 that can place web-like Copper Foil volume core paper pipe on the cooresponding two side of base.Web-like Copper Foil volume core paper pipe to be transported places the base groove support, can prevent that the web-like Copper Foil from vertically rolling along base, but because the outside of base upper groove support does not have baffle plate, the structure that the also unrestricted Copper Foil of packing case lid inside length direction vertically moves, this all can't be with the web-like Copper Foil in length and breadth to being completely fixed.The packing chest of this structure, in transportation as run into jolt, reason such as mould turnover, will cause the collision of web-like Copper Foil and tank wall or produce collision mutually between the web-like Copper Foil, cause web-like Copper Foil in the transportation be out of shape, wrinkling, influence product design.

The utility model content

Technical problem to be solved in the utility model provides a kind of web-like Copper Foil packing chest that improves distortion that the web-like Copper Foil may occur, phenomenon such as wrinkling in transportation.

For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:

Design a kind of web-like Copper Foil packing chest, comprise base and the case lid that cooperates with base, described base bottom is a base stage, and the edge upwards is formed with base wall in base stage, have recess downwards at two relative base wall end faces, the baffle plate that the recess outside has base wall to form; Be formed with two inner convex platforms on cooresponding two cover walls of two base wall, from the inner convex platform end face have downwards with described recess cooresponding in recess; Case lid is engaged on the base, and described recess docks with described interior recess and forms the circular port position.

The utility model has following remarkable advantage compared to existing technology:

The utility model improves on existing packing chest basis, changes the position of offering recess on the base wall, makes the recess outside that the baffle plate of base wall formation be arranged.Similar structure also is set on cover wall simultaneously, can fixes the web-like Copper Foil in the packing chest in casing.Thereby improved the safety factor of web-like Copper Foil packing chest greatly, avoided the relative displacement of Copper Foil finished product in packing chest, greatly reduce in transportation because shake, jolt, the web-like Copper Foil that reason caused distortion such as mould turnover, phenomenon such as wrinkling, guaranteed the quality of the interior product of packing chest.

Description of drawings

The structural representation that the base of the existing web-like Copper Foil packing chest of Fig. 1 and cover decompose;

Fig. 2 is the structural representation that base of the present utility model and cover decompose.

The specific embodiment

The utility model is described in further detail in conjunction with the accompanying drawings below by embodiment.

Referring to Fig. 2, a kind of web-like Copper Foil packing chest is made up of packing chest base 1 and case lid 2.The base bottom is a base stage 10, and along upwards being formed with base wall 11, the relative base wall of base stage is to being protruded with step in base stage.For the web-like Copper Foil 3 of the roll coil of strip core paper pipe of fixed placement in packing chest, the two base wall end faces relative at base have recess 110 downwards, the baffle plate 111 that the recess outside has base wall to form; The volume core paper pipe 31 of web-like Copper Foil 3 can be placed on the described recess.Because there is baffle plate 111 in the recess outside, can avoid web-like Copper Foil side travel.

In order to make the web-like Copper Foil of placing in the packing chest fixing that is positioned fully, also doing corresponding structure in case lid improves, with cooresponding two cover walls of two base wall on form two inner convex platforms 20, from the boss end face offer downwards with described recess 110 cooresponding in recess 201, when case lid is engaged on the base, the cover wall end face is engaged on the step surface of base evagination, and base wall end face recess docks formation circular port position with recess in the case lid, the volume core paper pipe of web-like Copper Foil just is arranged in the circular port position that forms behind base and the case lid snapping, for the web-like Copper Foil is tightened, can make base wall end face recess docks the circular port position that forms with recess in the case lid diameter just is the external diameter of web-like Copper Foil volume core paper pipe.The volume core paper pipe of web-like Copper Foil just is stuck in the packing chest in the formed circular port position tightly like this; by this can be vertically fixing web-like Copper Foil; avoided vertical relative displacement of the relative packing chest of Copper Foil,, protected the Copper Foil in the packing chest effectively even when mould turnover, also be not easy the Copper Foil displacement.

Claims

1, a kind of web-like Copper Foil packing chest, the case lid (2) that comprises base (1) and cooperate with base is characterized in that:

Described base bottom is base stage (10), along upwards being formed with base wall (11), has recess (110) downwards at two relative base wall end faces in base stage, the baffle plate (111) that the recess outside has base wall to form.

2, web-like Copper Foil packing chest according to claim 1 is characterized in that:

Be formed with two inner convex platforms (20) on described and cooresponding two cover walls of two base wall, from the inner convex platform end face have downwards with described recess (110) cooresponding in recess (201),

When case lid was engaged on the base, described recess docked with described interior recess and forms the circular port position.
