1. Field of the Invention
This invention relates to a tape-roll supporting device, particularly to one able to steadily receive thereon a tape roll of different widths.
2. Field of the Invention
A conventional tape-roll supporting device for receiving a tape roll, such as a label-tape roll, a packaging-strap roll or an adhesive-tape roll, includes a shaft and two side covers. The two side covers are respectively fixed with the opposite ends of the shaft and form an interval of a fixed width between them. Thus, a tape roll fitted around the shaft can be restricted in position by the two side covers.
However, the distance between the two side covers of the conventional tape-roll supporting device is fixed and impossible to be adjusted so only a specific-sized tape roll can be fitted therebetween.
The objective of the invention is to offer a tape-roll supporting device consisting of a shaft, a threaded tube and two side covers. The shaft is to be assembled on a machine body, and the threaded tube is rotatably fitted around the outer side of the shaft for fitting thereon a tape roll of different widths.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a tape-roll supporting device assembled with a label-pasting machine in the present invention, as shown in
The machine body 10 is provided with a grip 11 extending downward from the bottom and a label guiding roller unit 12 on the upper side and also has its opposite sides respectively. provided with a vertical combining plate 13 space apart at a preset distance. The two combining plates 13 are respectively bored with an insert hole 131 aligned to each other.
The tape-roll wheel holder 20 for supporting a tape roll 30 is fitted between the two insert holes 131 of the two combining plates 13. The tape-roll wheel holder 20 consists of a shaft 21, a threaded tube 22 and two side covers 23.
The shaft 21 has an outer end formed with a rim 211 with a comparatively large diameter and an inner end formed with male threads 212. The inner end with the male threads 212 of the shaft 21 can be inserted through the two insert holes 131 of the two combining plates 13, letting the male threads 212 extending out of the combining plate 13.
The threaded tube 22 is rotatably fitted around the shaft 21 for fitting and positioning thereon a tape roll 30 of different widths.
The two side covers 23 are respectively bored with a threaded hole 231 in the center to be threadably combined with the opposite ends of the threaded tube 22. The two side covers 23 can be rotatably adjusted in position so as to clamp the tape roll 30 fitted on the threaded tube 22. The inner end with the male threads 212 of the shaft 21 is screwed with a locking nut 213, letting the rim 211 and the locking nut 213 respectively and firmly secured on the opposite outer surfaces of the two combining plate 13.
In assembling, as shown in
In using, when the label tape 31 on the label tape roll 30 is pulled outward, the label tape roll 30 clamped by the two side covers 23 will be actuated to turn together with the threaded tube 22, letting the threaded tube 22 rotate around the shaft 21. Thus, the label tape 31 can be released smoothly and steadily for carrying out pasting work.
The tape-roll supporting device in the present invention can also be employed for fitting a packaging strap roll 30 or an adhesive-tape roll 30. If it is employed for fitting a packaging strap roll 30, as shown in
If the tape-roll supporting device of this invention is employed for fitting an adhesive-tape roll 30, as shown in
To sum up, the tape-roll supporting device of this invention is able to closely clamp a tape roll 30 in position to prevent the tape roll 30 from sliding sideward and swaying to enable the tape roll 30 to release tape smoothly and steadily, elevating efficiency and quality in tape pasting or strap packaging and having extensive applicability.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
