Description

Technical Field

[0001] The utility model relates to the technical field of zipper production, in particular to a placement type yarn drum tape feeding device. Background Art

[0002] At present, the production process of zipper tape mainly includes the following procedures: weaving (weaving the tapes on both sides of the zipper), shaping (shaping the tapes), winding (winding the tapes on the yarn drum to form tape rolls), dyeing (rolling the rolled tapes into the dyeing vat for dyeing), and drying (drying the dyed tapes).

[0003] In the field of dyeing of zipper tapes, the zipper tape wound on a yarn drum needs to be placed in a dyeing machine for dyeing in advance. After dyeing, the zipper tape needs to be withdrawn from the yarn drum and transported to a dryer for drying the dye solution.

[0004] A device required for withdrawing the zipper tape from the bobbin is a tape unwinding machine / tape feeding machine, such as the patent CN201410493445.8 previously applied by the inventor of the utility model, which discloses a zipper chain autonomous tape feeding machine, including a first mounting frame and a second mounting frame arranged relatively, the first mounting frame and the second mounting frame are respectively mounted with a driving shaft and a driven shaft, the front ends of the driving shaft and the driven shaft close to each other are respectively fixed with a left top tightening head and a right top tightening head, the driving shaft and the driven shaft are coaxial, and the driving shaft is driven by a servo motor. During operation, by adjusting the distance between the left top tightening head and the right top tightening head and the horizontal height of the lifting mechanism, the bobbin is firmly clamped between the left top tightening head and the right top tightening head, and then the connector at one end of the zipper chain on the bobbin is connected to the drying drum in the dryer, the dryer drum and the motor are started, and the autonomous conveying of the zipper chain begins.

[0005] However, in the prior art including the above-mentioned prior patent, the distance between the left and right tightening heads for clamping and fixing the yarn bobbin cannot be adjusted, and the unwinding machine / feeding machine can only be used for yarn bobbins of fixed size. This is problematic for the production of small batches of zipper tapes, or even for the trial production of zipper tape samples, because these yarn bobbins are of different sizes and are frequently replaced. In addition, the unwinding machine / feeding machine of the prior art clamps the yarn bobbins at both ends, which requires lifting the yarn bobbins first, which is cumbersome, time-consuming and labor-intensive to operate. Summary of the invention

[0006] In view of this, the purpose of the utility model is to provide a placement type yarn bobbin tape feeding device, which can be suitable for yarn bobbins of different sizes and can directly place the yarn bobbins without lifting the yarn bobbins.

[0007] In order to achieve the above object, the utility model provides the following technical solutions:
