Abstract

A sleeve wrapping device includes a first fixing base, a second fixing base, a first supporting frame protruded from the first fixing base, a second supporting frame protruded from the second fixing base, a first roller mounted on the first supporting frame, a second roller mounted on the second supporting frame, and a sleeve wrapping film comprising a substrate and a plurality of adhesive layers. The first roller and the second roller move back and forth relative to the first supporting frame and the second supporting frame. The sleeve wrapping device is switched between a first state that the first roller and the second roller are in contact with each other and a second state that the first roller and the second roller are separated. The substrate winds the first roller and the second roller.

First claim

What is claimed is:

1. A sleeve wrapping device comprising:
a first fixing base;
a second fixing base;
a first supporting frame protruded from a side of the first fixing base;
a second supporting frame protruded from a side of the second fixing base facing the first supporting frame;
a first roller rotatably mounted on the first supporting frame;
a second roller rotatably mounted on the second supporting frame; and
a sleeve wrapping film comprising a substrate and a plurality of adhesive layers on a side of the substrate;
wherein the first roller moves back and forth relative to the first supporting frame and the second supporting frame, the second roller moves back and forth relative to the first supporting frame and the second supporting frame, thereby causing the first roller and second roller to become closer or further away from each other; the sleeve wrapping device is switchable between a first state and a second state, wherein in the first state, the first roller and the second roller are in contact with each other, and in the second state, the first roller and the second roller are separated; the plurality of the adhesive layers are spaced from each other; the substrate sequentially winds around the first roller and the second roller, when the sleeve wrapping device is switched from the second state to the first state, two end portions of one of the plurality of the adhesive layers are connected to surround a target object.

2. The sleeve wrapping device of claim 1 , wherein the first supporting frame is elastically connected to the first fixing base via a first elastic component, the second supporting frame is elastically connected to the second fixing base via a second elastic component.

3. The sleeve wrapping device of claim 2 , wherein the sleeve wrapping device further comprises a first connecting rod and a second connecting rod; the first connecting rod is connected to the first supporting frame, and the first roller is rotatably sleeved on the first connecting rod; the second connecting rod is connected to the second supporting frame, and the second roller is rotatably sleeved on the second connecting rod.

4. The sleeve wrapping device of claim 1 , wherein the sleeve wrapping device further comprises a first connecting rod and a second connecting rod; the first connecting rod is elastically connected to the first supporting frame via a first elastic component, and the first roller is rotatably sleeved on the first connecting rod; the second connecting rod is elastically connected to the second supporting frame via a second elastic component, and the second roller is rotatably sleeved on the second connecting rod.

5. The sleeve wrapping device of claim 4 , wherein the first supporting frame is elastically connected to the first fixing base via a third elastic component, the second supporting frame is elastically connected to the second fixing base via a fourth elastic component.

6. The sleeve wrapping device of claim 1 , wherein the sleeve wrapping device further comprises a discharge box and a receiving box, the discharge box receives a first end portion of the sleeve wrapping film, the receiving box receives a second portion of the sleeve wrapping film.

7. The sleeve wrapping device of claim 6 , wherein the sleeve wrapping device further comprises a third roller received in the receiving box for winding the second portion of the sleeve wrapping film.

8. The sleeve wrapping device of claim 7 , wherein the sleeve wrapping device further comprises a driving device connected to the third roller for driving the third roller to rotate.

9. The sleeve wrapping device of claim 1 , wherein the sleeve wrapping device comprises two first supporting frames and two second supporting frames, the first supporting frames are mounted on the first fixing base and spaced from each other, a first connecting rod connects the first supporting frames, and the first roller is rotatably sleeved on the first connecting rod; two second supporting frames are mounted on the second fixing base and spaced from each other, a second connecting rod connects the second supporting frames, and the second roller is rotatably sleeved on the second connecting rod.

10. The sleeve wrapping device of claim 1 , wherein the first roller and the second roller are at a same height.

11. The sleeve wrapping device of claim 1 , wherein the first supporting frame and the second supporting frame are parallel to each other.
