Description

Technical Field

[0001] The present invention relates to the field of cigarette manufacturing, and more particularly, to a deviation rectifying device for the inner lining paper of the second wheel and an inner lining paper wrapping system. Background Art

[0002] The GDX2 packaging machine is a widely used cigarette packaging equipment in China. When packaging cigarettes with this type of packaging machine, the inner lining paper is cut and then conveyed into the entrance of the second wheel and waits for the arrival of the cigarette group before crossing the bridge. The pusher rod and the cigarette receiving rod at the second wheel hold the cigarette group and pass through the entrance bridge of the second wheel and enter the die box of the second wheel. During this period, the cigarette group is wrapped by the inner lining paper. When the cigarette group completely enters the die box of the second wheel, the second wheel rotates to realize the folding of the inner lining paper.

[0003] In actual work, since the filter tip of the cigarette is pasted with tipping paper, the diameter of the filter tip is slightly larger than that of the lit end of the cigarette. This makes the upper and lower sides of the inner lining paper subject to uneven frictional forces from the upper and lower inner sides of the entrance bridge of the second wheel when the cigarette group is wrapped by the inner lining paper and passes through the entrance bridge of the second wheel, resulting in the skew of the inner lining paper. In addition, problems such as uneven paper thickness of the inner lining paper, wear of the upper and lower inner sides of the entrance bridge of the second wheel, and adhesion of dirt to the upper and lower inner sides of the entrance bridge of the second wheel will all cause uneven force on the inner lining paper, ultimately resulting in the problem of skew of the inner lining paper.

[0004] The existing method to solve the problem of skew of the inner lining paper at the second wheel is to reduce the distance between the pusher rod and the cigarette receiving rod and increase the clamping force between them, thereby reducing the skew degree of the inner lining paper. However, as the pusher rod and the cigarette receiving rod wear, the skew degree of the inner lining paper will increase. Moreover, too large a clamping force between the pusher rod and the cigarette receiving rod will also increase the possibility of cigarette loss.

[0005] Therefore, how to provide a device that can effectively reduce the skew of the inner lining paper of the second wheel has become a technical problem urgently to be solved in this field. Summary of the Invention

[0036] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered as part of the specification.

[0037] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Thus, other examples of exemplary embodiments may have different values.

[0038] As Figure 1 shown, the deviation rectifying device for the inner liner paper of the second wheel of the present disclosure includes a vibration transmission mechanism and a vibration mechanism.

[0039] The vibration transmission mechanism includes a vibration transmission disk 1, a vibration transmission disk fixing member 2, and a vibration guiding member 3.

[0040] The vibration transmission disk 1 is located between the entrance bridge of the second wheel and the vibration guiding member 3. A protrusion 100 is provided on one side of the vibration transmission disk 1 adjacent to the entrance bridge of the second wheel. The protrusion 100 is in contact with the outer surface of the entrance bridge of the second wheel, and fixing holes are circumferentially arranged around the protrusion 100. The provision of the protrusion 100 on the vibration transmission disk 1 helps to reduce the contact area between the vibration transmission disk 1 and the entrance bridge of the second wheel, so that the energy of vibration is more concentrated, effectively increasing the vibration frequency of the entrance bridge of the second wheel. The vibration transmission disk fixing member 2 cooperates with the fixing holes to fix the vibration transmission disk 1 on the entrance bridge of the second wheel. The vibration transmission disk fixing member 2 can be, for example, a bolt or a fixing pin, etc.

[0041] One end of the vibration guiding member 3 is connected to the side of the vibration transmission disk 1 away from the protrusion 100, and the other end of the vibration guiding member 3 is connected to the vibration mechanism. The connection between the vibration guiding member 3 and the vibration transmission disk 1 can be achieved by means such as welding or bolt connection. The connection between the vibration guiding member 3 and the vibration mechanism can be achieved by connecting with a connecting member such as a bolt.

[0042] The vibration mechanism can be used to drive the vibration guiding member 3 to vibrate, so that the vibration guiding member 3 transmits the vibration to the vibration transmission disk 1, and the vibration transmission disk 1 transmits the vibration to the entrance bridge of the second wheel. The vibration mechanism can be, for example, a mechanical vibration mechanism or an ultrasonic vibration mechanism, etc.

[0043] The deviation rectifying device for the inner liner paper of the second wheel of the present disclosure transmits the vibration generated by the vibration mechanism to the entrance bridge of the second wheel through the vibration transmission mechanism, causing the entrance bridge of the second wheel to vibrate. As a result, the contact between the inner liner paper and the entrance bridge of the second wheel changes from continuous contact to intermittent contact, reducing the friction between the inner liner paper and the entrance bridge of the second wheel, and effectively alleviating the skew of the inner liner paper of the second wheel.

[0044] In an embodiment of the deviation rectifying device for the inner lining paper of the second wheel in the present disclosure, in order to more effectively control the vibration of the bridge at the entrance of the second wheel, the protrusion 100 is located at the center of the vibration transmission disk 1. Specifically, during implementation, the protrusion 100 can be in a regular shape, for example, cylindrical or cuboid-shaped, etc.

[0045] In an embodiment of the deviation rectifying device for the inner lining paper of the second wheel in the present disclosure, the protrusion 100 has a truncated cone structure, and the diameter of the cross-section perpendicular to the height of the protrusion 100 gradually decreases in the direction from the vibration transmission disk 1 to the bridge at the entrance of the second wheel. The protrusion 100 with this structure is beneficial to more effectively concentrate the energy of the vibration and make the vibration of the bridge at the entrance of the second wheel more stable.

[0046] Furthermore, in order to more conveniently control the vibration of the bridge at the entrance of the second wheel, the ratio of the height of the protrusion 100 to the thickness of the bridge at the entrance of the second wheel is 1:(10 - 30).

[0047] In an embodiment of the deviation rectifying device for the inner lining paper of the second wheel in the present disclosure, the vibration transmission disk fixing member 2 is a bolt. Through the cooperation of the bolt with the fixing hole on the vibration transmission disk 1 and the installation hole on the bridge at the entrance of the second wheel, the vibration transmission disk 1 can be conveniently installed on the bridge at the entrance of the second wheel.

[0048] In an embodiment of the deviation rectifying device for the inner lining paper of the second wheel in the present disclosure, in order to more stably transmit the vibration to the vibration transmission disk 1, the vibration guiding member 3 has a truncated cone structure, and the diameter of the cross-section perpendicular to the height of the vibration guiding member 3 gradually decreases in the direction from the vibration guiding member 3 to the vibration transmission disk 1.

[0049] Furthermore, the vibration guiding member 3 and the vibration transmission disk 1 are integrally formed to improve the structural strength of the vibration transmission mechanism.

[0050] In an embodiment of the deviation rectifying device for the inner lining paper of the second wheel in the present disclosure, the vibration mechanism includes a transducer 4, a piezoelectric ceramic sheet 5, an end cover 6, and a vibration mechanism fixing member 7.

[0051] The transducer 4, the piezoelectric ceramic sheet 5, and the end cover 6 are arranged in sequence along the direction away from the vibration guiding member 3. The vibration mechanism fixing member 7 can be used to install the transducer 4, the piezoelectric ceramic sheet 5, and the end cover 6 on the vibration guiding member 3. The vibration mechanism fixing member 7 can be, for example, a bolt, etc.

[0052] The vibration mechanism in this embodiment has a simple structure and is easy to implement.

[0053] As Figure 2 and Figure 3 shown, the present disclosure also provides a system for wrapping inner lining paper.

[0054] The inner liner paper wrapping system includes the second wheel die box 8, the second wheel inlet cross-bridge 9, the cigarette receiving rod 10, the cigarette pushing rod 11, and the second wheel inner liner paper deviation rectifying device of the present disclosure.

[0055] The second wheel inlet cross-bridge 9 is connected to the opening side of the second wheel die box 8. The cigarette receiving rod 10 is located inside the second wheel die box 8, and the cigarette pushing rod 11 is located outside the second wheel die box 8 and is arranged corresponding to the cigarette receiving rod 10. The cigarette group 02 can be clamped between the cigarette receiving rod 10 and the cigarette pushing rod 11.

[0056] The second wheel inner liner paper deviation rectifying device is installed on the top of the second wheel inlet cross-bridge 9. The top of the above-mentioned second wheel inlet cross-bridge 9 refers to the side of the part of the second wheel inlet cross-bridge 9 located above the cigarette group 02 that is far away from the cigarette group 02.

[0057] The working process of the inner liner paper wrapping system of the present disclosure is as follows: The inner liner paper 01 is cut and then conveyed into the front of the second wheel inlet cross-bridge 9 to wait for the arrival of the cigarette group 02. The cigarette pushing rod 11 and the cigarette receiving rod 10 clamp the cigarette group 02 and pass through the second wheel inlet cross-bridge 9 and enter the second wheel die box 8, and the cigarette group 02 is wrapped by the inner liner paper 01 during this period.

[0058] In an embodiment of the inner liner paper wrapping system of the present disclosure, in order to vibrate the second wheel inlet cross-bridge 9 more stably, a plurality of second wheel inner liner paper deviation rectifying devices are arranged along the length direction of the second wheel inlet cross-bridge 9.
