Description

Label area unreels equipment

Technical Field

The invention relates to the technical field of label printing, in particular to label tape unwinding equipment.

Background

The label is printed matter for identifying the relevant description of the product, mostly self-adhesive label on the back, or some labels without adhesive during printing, and the label with adhesive is commonly called as 'self-adhesive label'.

At present, in the production of labels, workers often set a label tape roll on an unreeling device, unreel the label tape from the unreeling device and supply the label tape to a label printing device; the label printed by the label printing apparatus is then cut by a label die cutter to complete the production of the label.

The existing label tape unreeling device comprises a rack 1, wherein a mounting roller 2 used for mounting a label tape roll is arranged on a rotating frame on the rack 1, a traction roller 3 is arranged on the rack in a manner that the mounting roller 2 rotates along one side of the axis of the mounting roller 2 horizontally perpendicular to the rack, a driving motor used for driving the traction roller is further arranged on the rack, a pressing roller 4 used for pressing the label tape onto the traction roller is further arranged on the rotating frame right above the traction roller, and the mounting roller 2, the traction roller 3 and the pressing roller 4 are arranged in parallel. In the practical application, the staff can penetrate the label area to compressing roller 4 and carry over pinch rolls 3 between to by driving motor drive carry over pinch rolls 3 rotations, and then pull the label and supply with to label lithography apparatus, and unreel the label tape roll.

However, after the driving motor stops operating, the mounting roller and the label tape roll continue to rotate due to inertia and unreel the label tape roll; at the moment, the unreeled label tape is accumulated between the mounting roller and the drawing roller, and the label tape arches upwards between the mounting roller and the drawing roller along with the continuous rotation of the mounting roller and the label tape roll; when the arched label tape reaches a certain height, the label tape will incline and fall to two sides of the axial direction of the traction roller, and the label tape between the installation roller and the traction roller is folded; if the driving motor is started to drive the traction roller to pull the label belt at the moment, the label belt is easily folded and pulled between the pressing roller and the traction roller, bad label belt sections are generated, cutting operation of some bad label belts or labels is brought, and great waste is caused.

Disclosure of Invention

In view of the above technical problems, an object of the present invention is to provide a label tape unwinding apparatus, which limits the height of a notepaper tape unwound by inertia by means of a limiting assembly, reduces the occurrence of label arching and toppling and folding caused by inertia unwinding, and helps to reduce the generation of defective label tape sections.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a label area unwinding equipment, includes the frame, it is provided with installation roller, carry over pinch rolls and pinch rolls to rotate in the frame, still be provided with in the frame and be used for driving carry over pinch rolls pivoted drive assembly, the frame is located the last side frame between installation roller and the carry over pinch rolls and is limited subassembly.

By adopting the technical scheme, in actual application, a worker can install the label tape roll on the installation roller and penetrate the unreeling end of the label tape roll between the pressing roller and the traction roller; at the moment, the label tape is pressed on the traction roller by the pressing roller, and the traction roller is driven by the driving assembly to rotate, so that the label tape roll is unreeled. When the driving assembly stops driving the traction roller, the mounting roller and the label tape roll continuously rotate due to inertia and unreel the label tape roll, the unreeled label tape is accumulated between the mounting roller and the traction roller, and the label tape upwards arches between the mounting roller and the traction roller along with the continuous rotation of the mounting roller and the label tape roll; when the arched label tape is higher, the arched label tape is blocked by the limiting component, and the arched label tape is partially bent downwards and falls downwards under the action of gravity.
