Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tape winding devices, in particular to a lifting type roll changing mechanism. Background Art

[0002] The tape is composed of two parts: a base material and an adhesive. The adhesive is attached to the surface of the base material. When in use, two or more unconnected objects are connected together through the adhesive.

[0003] The tape needs to be rolled and formed during the production process. In the specific implementation process, the base material needs to be rolled onto the receiving roller first, and then one end of it is extended into the interface of the roll-changing mechanism, and finally the tape is pulled out at the interface as needed. However, when the rolled tape needs to be replaced, since the upper and lower plates of the roll-changing mechanism are fixedly set and the gap is small, manual threading is time-consuming and labor-intensive, and the threading efficiency is low, which affects the subsequent processing progress and cannot meet the fast-paced production requirements. Utility Model Content

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A lifting roll changing mechanism comprises a material pressing frame, a material pressing piece and a lifting assembly, wherein:

[0007] The press frame is provided with a press bottom plate in the horizontal direction, the press bottom plate is configured to at least carry the adhesive tape, the press piece is arranged above the press bottom plate in a liftable manner, and the length of the press piece is greater than that of the press bottom plate.

[0008] The lifting assembly includes two lifting units, which are symmetrically arranged at both ends of the pressing frame in the horizontal direction. The movable ends of the two lifting units are respectively connected to the two ends of the pressing piece. The two lifting units are configured to drive the pressing piece to rise to a high position or a low position. When the pressing piece is in a low position, there is a gap between the pressing piece and the pressing bottom plate for placing the tape.

[0009] Furthermore, each of the jacking units includes a jacking drive and a jacking member, the fixed end of the jacking drive is installed on the pressing member, the movable end of the jacking drive is connected to the jacking member, and the jacking drive drives the jacking member to rise and fall to drive the pressing member to rise to a high position or a low position.

[0010] Furthermore, the lifting drive member adopts a lifting cylinder.

[0011] Furthermore, a protruding plate is provided on the bottom surface of the material pressing piece on the outer side of the material pressing bottom plate, and when the lifting driving member drives the lifting member to rise, the lifting member abuts against the protruding plate to drive the material pressing piece to rise.

[0012] Furthermore, limiting members are provided through both ends of the pressing bottom plate in the horizontal direction, and the top end of the limiting member extends to the upper end surface of the pressing bottom plate to limit the downward movement stroke of the pressing member.

[0013] Compared with the prior art, the beneficial effect of the jacking-type roll changing mechanism is: two jacking units are used to drive the pressing piece to a high position or a low position at both ends to change the distance between the pressing bottom plate and the pressing piece. It not only has a simple structure and ingenious design, but also changes the distance between the pressing bottom plate and the pressing piece. Manual threading saves time and effort, greatly improves the threading efficiency, and meets the requirements of fast-paced production. BRIEF DESCRIPTION OF THE DRAWINGS
