Problems solved by technology

[0005] However, after the driving motor stops running, the installation roller and the label tape will continue to rotate due to inertia and unwind the label tape; at this time, the unrolled label tape will accumulate between the installation roller and the traction roller, and with the As the installation roller and the label tape continue to rotate, the label tape will arch upward between the installation roller and the traction roller; when the arched label tape reaches a certain height, it will tilt to both sides of the traction roller axis, and make The label tape between the installation roller and the traction roller is folded; if the drive motor is turned on to drive the traction roller to pull the label tape, it is easy to cause the folded label tape to be drawn between the pinch roller and the traction roller, resulting in a bad label tape section. And bring some bad label tape or label cutting operation, resulting in great waste

Embodiment 1

[0040] see figure 2 and image 3 , a label tape unwinding device, comprising a frame 1, the turret on the frame 1 is provided with a mounting roller 2, a traction roller 3 and a pinch roller 4, and the mounting roller 2, the traction roller 3 and the pinch roller 4 are parallel . Frame 1 comprises two support plates 11 that are vertically arranged, and two support plates 11 are arranged in parallel, and the two ends of installation roller 2, traction roller 3 and hold-down roller 4 all rotate on two support plates 11 respectively. Above; the traction roller 3 is located on the side of the installation roller 2 that is horizontal and perpendicular to the axial direction of the installation roller 2 , and the pinch roller 4 is located directly above the installation roller 2 . The frame 1 is also provided with a drive assembly 5 for driving the traction roller 3 to rotate. In the present embodiment, the drive assembly 5 selects a servo motor, and the servo motor is fixed on a...

Embodiment 2

[0049] see Figure 4 and Figure 5 , a label tape unwinding device, the difference between it and Embodiment 1 is that: a sliding frame 8 is arranged up and down on the frame 1, and the limit assembly 6 includes a height limit rod 63, and the height limit rod 63 is fixed on the slide On the moving frame 8, and the frame 1 is also provided with a driving member for driving the sliding frame 8 to go up and down. In practical application, the staff can drive the sliding frame 8 and the height limiting rod 63 up and down by means of the driving member, so that the height limiting rod 63 has a height limiting effect on various label tape rolls with different diameters.

[0050] The sliding frame 8 comprises a slide block, and two support plates 11 are vertically provided with a chute 112, the slide block corresponds to the chute 112 one by one, and the two slide blocks are respectively embedded in the two chute 112 and connected with the chute. 112 slip fit. The axial direction ...

Abstract

The invention discloses a label tape unwinding device, which relates to the technical field of label printing. The driving assembly that drives the traction roller to rotate, and the upper side of the frame between the installation roller and the traction roller is provided with a limit assembly. The invention has the advantages of reducing the occurrence of arching, toppling and folding of labels unwound by inertia, and helping to reduce the generation of defective label strips.

Description

technical field [0001] The invention relates to the technical field of label printing, in particular to a label tape unwinding device. Background technique [0002] Labels are printed materials used to identify the relevant instructions of their own products. Most of them are printed with glue on the back, and some are printed without glue, and the labels with glue are commonly known as "self-adhesive labels". [0003] At present, in the production of labels, the staff often set up the label tape roll on the unwinding equipment, and the unwinding equipment unwinds the label tape and supplies it to the label printing equipment; then, the label printed by the label printing equipment will be printed by the label mold Cutting machine to complete the label production. [0004] Existing a kind of label tape unwinding equipment, see figure 1 , which includes a frame 1, the turret on the frame 1 is provided with a mounting roller 2 for mounting the label tape roll, and the frame ...
