The prior art can cause the waste of packaging material at first, increases purchasing cost, and the polishing pipe can scatter frame, the mutual extrusion of paper tube in the packaging process secondly, leads to the quality impaired. In addition, the labor cost of the packaging mode is extremely high, the packaging quantity is uncertain, and the working strength of storage personnel is greatly increased.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a transport case of dustless paper pipe for lithium cell diaphragm, effectual protection paper pipe can not extrude, damaged, pollute each other, the concentricity changes in the transportation, effectively reduces the packaging cost, improves handling efficiency.

Therefore, the utility model provides a transport case of lithium cell dust-free paper pipe for diaphragm, include: base, box and case lid, one side of base is provided with first slot and second slot, and the length direction parallel arrangement of base is followed to first slot and second slot, and box fixed mounting is on the base, and the inside of box is provided with the grid, and the grid becomes the storehouse of placing that the array was arranged with the inner space partition of box, and the fiber container is placed in placing the storehouse, and the case lid joint is in the top of box.

Further, the storage bin is of a cuboid columnar structure.

Furthermore, the inner side wall of the placing bin is adhered with EVA foam.

Furthermore, the box body is made of plastic.

Further, the base is made of stainless steel pipes through welding.

Further, the cross section of the first slot and the second slot is rectangular.

The utility model provides a transport case of dust-free paper pipe for lithium battery diaphragm, include: base, box and case lid, one side of base is provided with first slot and second slot, and the length direction parallel arrangement of base is followed to first slot and second slot, and box fixed mounting is on the base, and the inside of box is provided with the grid, and the grid becomes the storehouse of placing that the array was arranged with the inner space partition of box, and the fiber container is placed in placing the storehouse, and the case lid joint is in the top of box. All paper tubes are filled into a plastic box with the storage bins arranged in an array mode through the same bullet filling, and mutual extrusion among the paper tubes in the transportation process is avoided. The plastic box body and the stainless steel base enable the structure of the transport box to be stable and not to deform in the transport process.

The utility model provides a transport case of dust-free paper tube for lithium battery diaphragm, which greatly reduces the packing material cost and labor cost of the paper tube in the aspect of controlling cost; in the aspect of storage and transportation, the transport box body is fixed in size, is neatly and conveniently stored after being packaged, and improves the loading and unloading efficiency; in the aspect of protection effect, the paper tubes can be effectively protected from mutual extrusion, damage, pollution and change of concentricity in transportation. In addition, this transport case furthest has guaranteed the compressive strength of paper pipe, in the rolling process of follow-up lithium cell diaphragm, has guaranteed tension, has improved the yields of product.
