[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0022] A dual-rotor drum for labeling conical bottles, such as Figures 1-4 As shown, the device includes two sets of cylindrical drums 1 arranged vertically. The two sets of drums 1 rotate synchronously. Each set of drums 1 includes an upper base plate 2, a lower base plate 3, and multiple support columns 4 arranged in a circular array between the upper base plate 2 and the lower base plate 3, with their ends connected to the upper base plate 2 and the lower base plate 3 respectively by screws. The upper base plate 2 and the lower base plate 3 are generally circular. Multiple sets of drum sponges 5 are evenly spaced on the outer periphery of the upper base plate 2 and the lower base plate 3. The drum sponges 5 are fan-shaped and are connected to the upper base plate 2 and the lower base plate 3 respectively by bolts. The drum sponges 5 are used to support the label. In order to ensure that the drum sponges 5 have full contact with the conical bottle and attach the label to the conical bottle in a beautiful way, the material of the drum sponges 5 is sponge. When the width difference between the upper and lower parts of the label is large, in order to facilitate the operation of the finger clamp 15, the two sets of drums 1 can be arranged at an angle as needed. In this embodiment, the lower base plates 3 of the two sets of drums 1 are close to each other.

[0023] In this embodiment, there are four sets of rotating drum sponges 5. Between each pair of rotating drum sponges 5, there is a finger clamping assembly 6 that rotates synchronously with the upper seat plate 2 and the lower seat plate 3 to achieve label clamping or releasing.

[0024] Each set of drums 1 has a rotating support 7 at its center, and an outer sleeve 8 is fitted over the support 7. A drive motor is located at the bottom of the device, and the motor output shaft engages with the support 7 to cause the upper plate 2 and lower plate 3 to rotate synchronously. Each set of drums 1 has a support arm 9 near the upper plate 2. One end of the support arm 9 is fitted onto the support 7 and bolted to the outer sleeve 8. A cam 10, fitted onto the support 7, is also connected to the support arm 9. The cam 10 includes a large-diameter end 12 and a small-diameter end 11. During the rotation of the support 7, the support arm 9 does not rotate, while the cam 10 rotates. Each set of finger clamping assemblies 6 has a roller assembly 13 at its end that contacts the cam 10. Furthermore, the finger clamping assembly 6 includes a rotating shaft 14 that passes through the upper seat plate 2 and the lower seat plate 3. One or more finger clamps 15 are sleeved on the rotating shaft 14 and rotate with the rotating shaft 14. When the label is attached to the drum sponge 5, the finger clamps 15 can press the edge of the label to prevent the label from loosening. In this embodiment, the number of finger clamps 15 sleeved on each rotating shaft 14 is two sets. Those skilled in the art can also adjust the number of finger clamps 15 according to the size specifications of the label. The finger clamp 15 includes a clamping seat 19 that clamps on the rotating shaft 14. The clamping seat 19 is provided with a clamping piece 20. The clamping piece 20 includes a transition part 21 and a pressing part 22. In order to increase the pressing area between the pressing part 22 and the label, the drum sponge 5 side is provided with an adhesive strip 23 that is adapted to the pressing part 22. The label is attached to the drum sponge 5 and extends to the adhesive strip 23. The pressing part 22 presses against the adhesive strip 23 located on the drum sponge 5 side to press the label tightly.

[0025] Furthermore, the roller assembly 13 includes a connecting rod 16, a roller 17, and a tension spring 18. One end of the connecting rod 16 is clamped onto the rotating shaft 14 and its position is fixed by a clamping bolt. The other end is connected to the roller 17 through a pin. The roller 17 can rotate freely. One end of the tension spring 18 is connected to the middle of the connecting rod 16, and the other end is connected to the upper seat plate 2. The roller 17 always abuts against the cam 10 under the tension of the tension spring 18.

[0026] When the roller assembly 13 rotates synchronously with the upper seat plate 2 and the lower seat plate 3, and the roller 17 contacts the small-diameter end 11 of the cam 10, the rotating shaft 14 rotates under the action of the tension spring 18, the gripping fingers 15 open, and the pressing part 22 disengages from the adhesive strip 23. At this time, the label is completely attached to the conical flask. When the roller 17 contacts the large-diameter end 12 of the cam 10, the rotating shaft 14 rotates, the gripping fingers 15 close, and the pressing part 22 presses against the adhesive strip 23, thus clamping the label. Because different conical flasks have different shapes, in order to ensure perfect label attachment, the length of the transition part 21 in the gripping fingers 15 can be customized to a uniform size or different sizes as needed.

[0027] The working principle of this device is as follows: Figure 5As shown, the labels are stored in the label box 24. When the label plate 25 picks up the label and rotates to coincide with the station of the rotating drum 1, the gripper fingers 15 open to clamp the label paper on the label plate 25. At the same time, the label paper adheres to the sponge 5 of the rotating drum. When the bottle rotates into position, the label paper is pasted on the bottle. The gripper fingers 15 on the two sets of rotating drums 1 can be replaced according to the size of the label. When the label is conical, the length of the transition part 21 in the gripper fingers 15 can be adapted according to the shape of the label to ensure that the label is more flat and beautiful after it is pasted on the bottle.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
