[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] The present application embodiment discloses a label supply device for labeling paper towels. Figure 1 and Figure 2 A label supply device for paper towel labeling includes a frame, the frame 4 has a horizontal bottom plate placed on the ground and a side plate vertically installed on the horizontal bottom plate, other components of the labeling machine are installed on the horizontal bottom plate, and the label supply device is installed on the side plate. Specifically, the label supply assembly includes a label unwinding assembly, a labeling plate 5 and a waste paper rewinding assembly, and the labeling plate 5 is arranged between the label unwinding assembly and the waste paper rewinding assembly.

[0032] The label unwinding assembly includes an unwinding roller 11 and a first driver 12. The unwinding roller 11 is rotatably mounted on the frame 4. The unwinding disk 2 is mounted on the unwinding roller 11. The label paper 3 has a fixed end and a free end. The fixed end is fixed on the unwinding disk 2. The label paper 3 between the fixed end and the free end is wound on the unwinding roller 11. The first driver 12 is mounted on the side of the frame 4 opposite to the unwinding roller 11. The output end of the first driver 12 is connected to the unwinding roller 11 to drive the unwinding roller 11 to rotate. Preferably, the first driver 12 is composed of a forward and reverse motor and a reducer.

[0033] Reference Figure 3 When the first driver 12 drives the unwinding roller 11 to rotate, the free end of the label paper 3 extends toward the labeling machine along the surface of the labeling plate 5. The label paper 3 includes a label body layer 31 and a protective paper layer 32. The label body layer 31 has a smooth surface and an adhesive surface. The protective paper layer 32 is attached to the adhesive surface to provide protection for the adhesive surface during the unwinding process of the label paper 3. One end of the label paper 3 extending on the labeling plate 5 peels off the protective paper layer 32 to form an opening to expose the adhesive surface of the label body layer 31. Under the action of other components of the labeling machine, it contacts the surface of the paper towel to achieve labeling. The peeled protective paper layer 32 is collected under the action of the waste paper rewinding mechanism 9.

[0034] With the above structure, during the labeling process, the label unwinding mechanism 1 can continuously supply label paper 3 to the labeling machine, and at the same time, the waste paper rewinding mechanism 9 can continuously peel off and collect the protective paper layer 32 from the label body layer 31 .

[0035] Reference Figure 1 The waste paper winding mechanism 9 includes a second driver 92, a winding roller 91 and a traction roller group 93, wherein the winding roller 91 is rotatably mounted on the frame 4, and the mounting position is in the same plane as the unwinding roller 11, and the central axes of the two are parallel to each other. The second driver 92 is installed on the other side of the frame 4, and is used to drive the winding roller 91 to rotate in a certain direction. The traction roller group 93 is arranged between the labeling plate 5 and the winding roller 91. When the waste paper is wound, the end of the protective paper layer 32 is first pulled to bypass the traction roller group 93, and then fixed on the winding roller 91. As the winding roller 91 rotates, the protective paper layer 32 is wound. The specific composition of the above-mentioned traction roller group 93 is common knowledge and will not be elaborated here. The second driver 92 preferably drives the winding roller 91 to rotate by combining a forward and reverse motor and a gear transmission assembly.

[0036] Further, see Figure 4 A support frame 6 is installed at a position above the frame 4 corresponding to the labeling plate 5. The support frame 6 extends horizontally perpendicular to the installation surface. A mounting structure 7 is provided on the support frame 6. A rotating seat 8 is connected to the mounting structure 7. The labeling plate 5 is installed on the rotating seat 8. Specifically, the mounting structure 7 includes two connecting plates 71 spaced apart in the length direction of the support frame 6. A connecting arm 72 extending vertically downward is fixed on the surface of each connecting plate 71. The connecting arm 72 is further fixed to an adjusting arm 73 extending vertically downward. The rotating seat 8 is rotatably installed on the adjusting arm 73 to provide support for the labeling plate 5.

[0037] Furthermore, a longitudinal adjustment hole extending along the length direction of the support frame 6 is opened on the connecting plate 71, and a threaded hole is opened on the support frame 6 at a position corresponding to the longitudinal adjustment hole. When installing the connecting plate 71, the connecting plate 71 can be moved up and down so that the threaded hole corresponds to different positions of the longitudinal adjustment hole, and then fasteners (such as fastening bolts, etc.) are installed in the longitudinal adjustment hole and the threaded hole, so that the position of the connecting plate 71 can be fixed. The setting of the longitudinal adjustment hole makes it convenient for the staff to adjust the installation height of the connecting plate 71.

[0038] Furthermore, a longitudinal adjustment hole extending along the height direction of the connecting arm 72 is also provided on the adjusting arm 73 , and the installation height of the adjusting arm 73 can be adjusted according to the adjustment distance of the connecting plate 71 .

[0039] Reference Figure 5The rotating seat 8 includes a connecting portion 82 for connecting the adjusting arm 73, and a supporting portion 81 for connecting the labeling plate 5, wherein the connecting portion 82 is a circular plate-like structure, and an axial hole is opened at the center thereof, and a rotating shaft 83 is installed in the axial hole. Both ends of the rotating shaft 83 pass through the axial hole and are rotatably installed on the adjusting arm 73, so that the rotating seat 8 can rotate relative to the adjusting arm 73 along its central axis. The supporting portion 81 is integrally formed on one side of the connecting portion 82 and extends horizontally. The upper surface of the supporting portion 81 is the supporting surface, and the two sides of the lower surface of the labeling plate 5 are respectively placed on the supporting surface. An adjusting hole and a threaded hole are respectively opened at the corresponding positions of the labeling plate 5 and the supporting portion 81, wherein the adjusting hole extends along the length direction of the labeling plate 5. The same as the above-mentioned adjustment principle, by adjusting the corresponding positions of the adjusting hole and the threaded hole, the fasteners are installed in the adjusting hole and the threaded hole, and the labeling plate 5 and the supporting portion 81 can be fixed.

[0040] Furthermore, an arc-shaped adjustment hole is provided on the connecting portion 82 of the rotating seat 8, the center of the arc-shaped adjustment hole coincides with the center of the connecting portion 82, and a threaded hole is provided at the position of the adjusting arm 73 corresponding to the arc-shaped adjustment hole. The angle between the labeling plate 5 and the horizontal plane can be adjusted by rotating the rotating seat 8, and then the fastener is passed through the arc-shaped adjustment hole and the threaded hole to fix the position of the rotating seat 8.

[0041] In order to guide one end of the label paper 3 extending from the unwinding roller 11 so that it can extend to the labeling plate 5 more smoothly, the label unwinding mechanism 1 also includes a guide roller group 13 arranged between the labeling plate 5 and the unwinding roller 11, and the guide roller group 13 includes a first guide roller 131 and a second guide roller 132, wherein the first guide roller 131 is fixed to the support frame 6 through a mounting plate and is located above the mounting structure 7, and the second guide roller 132 is installed on the rotating seat 8 and is located above the labeling plate 5, and the end of the label paper 3 extending from the unwinding roller 11 sequentially bypasses the first guide roller 131 and the second guide roller 132 and falls on the labeling plate 5.

[0042] The implementation principle of a label supply device for paper towel labeling in an embodiment of the present application is as follows: a rolled label paper 3 is placed on a unwinding disk 2, and the unwinding disk 2 is mounted on a unwinding roller 11. As the first driver 12 drives the unwinding roller 11 to rotate, one end of the label paper 3 passes through the first guide roller 131 and the second guide roller 132 and extends to the labeling plate 5, and extends a certain length from the labeling plate 5. Then, the protective paper layer 32 of the label paper 3 is peeled off, and the end of the protective paper layer 32 is fixed to the winding roller 91 through a traction roller group 93. The winding roller 91 is driven to rotate by the second driver 92. At the same time, the labeling machine applies an external force to the label body layer 31 after the protective paper layer 32 is peeled off, so that the label body layer 31 adheres to the surface of the paper towel conveyed on the labeling machine.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
