Description

Technical Field

[0001] The present disclosure relates to the field of tobacco machinery, and particularly to a glue cylinder assembly and a cigarette production device. Background Art

[0002] At present, during the cigarette production process of cigarette production equipment, it is necessary to apply glue to the tipping paper and then perform tipping. Uneven and unstable gluing will directly lead to quality problems such as cigarette leakage, blistering, and head dropping, which have an adverse impact on product quality control and brand image. Whether the gluing is stable is closely related to whether the glue cylinder is accurately installed in place. Usually, the glue cylinder is installed manually, and some operational mistakes are inevitable during the installation process, resulting in the glue cylinder being installed out of place, which in turn leads to poor gluing and quality problems. Summary of the Utility Model

[0003] The purpose of the present disclosure is to provide a glue cylinder assembly and a cigarette production device to reduce the risk of installation errors of the glue cylinder.

[0004] The first aspect of the present disclosure provides a glue cylinder assembly, including:

[0005] A mounting seat provided with a first limiting portion and a second limiting portion;

[0006] A glue cylinder, including a cylinder body, a first positioning portion and a second positioning portion. The first positioning portion and the second positioning portion are oppositely arranged on both sides of the cylinder body along a first direction. The first positioning portion is mounted on the first limiting portion, and the second positioning portion is mounted on the second limiting portion. The first limiting portion and the second limiting portion are configured to jointly limit the positions of the first positioning portion and the second positioning portion along the first direction and a second direction perpendicular to the first direction, so as to limit the position of the glue cylinder relative to the mounting seat;

[0007] An adjusting mechanism, including a handle, a rotating shaft and a third limiting portion. The rotating shaft is arranged on the mounting seat and its axis is arranged along the second direction. The handle is arranged on one side of the glue cylinder along the second direction. The handle is drivingly connected to the rotating shaft and is configured to drive the rotating shaft to rotate around the second direction. The third limiting portion is arranged on the handle and extends towards the side of the handle along the second direction close to the glue cylinder; and

[0008] A bracket configured to support the cylinder body. The bracket is connected to the rotating shaft to drive the glue cylinder to move along a third direction perpendicular to both the first direction and the second direction in response to the rotation of the handle.

[0009] According to some embodiments of the present disclosure,

[0010] The first limiting portion and the first positioning portion form a pin positioning structure; and / or

[0011] The second limiting portion and the second positioning portion form a pin positioning structure.

[0012] According to some embodiments of the present disclosure,

[0035] Referring to Figures 1 to 6 , some embodiments of the present disclosure provide a glue cylinder assembly, including a mounting base 1, a glue cylinder 2, an adjusting mechanism, and a bracket 4.

[0036] The mounting base 1 is provided with a first limiting portion 11 and a second limiting portion 12.

[0037] The glue cylinder 2 includes a cylinder body 23, a first positioning portion 21, and a second positioning portion 22. The first positioning portion 21 and the second positioning portion 22 are oppositely arranged on both sides of the cylinder body 23 along the first direction x. The first positioning portion 21 is mounted on the first limiting portion 11, and the second positioning portion 22 is mounted on the second limiting portion 12. The first limiting portion 11 and the second limiting portion 12 are configured to jointly limit the positions of the first positioning portion 21 and the second positioning portion 22 along the first direction x and the second direction y perpendicular to the first direction x, so as to limit the position of the glue cylinder 2 relative to the mounting base 1.

[0038] The adjusting mechanism includes a handle 31, a rotating shaft 33, and a third limiting portion 32. The rotating shaft 33 is disposed on the mounting base 1 and its axis is arranged along the second direction y. The handle 31 is disposed on one side of the glue cylinder 2 along the second direction y. The handle 31 is drivingly connected to the rotating shaft 33 and is configured to drive the rotating shaft 33 to rotate about the second direction y. The third limiting portion 32 is disposed on the handle 31 and extends toward the side of the handle 31 that is closer to the glue cylinder 2 along the second direction y.

[0039] The bracket 4 is configured to support the cylinder body 23. The bracket 4 is connected to the rotating shaft 33 so as to drive the glue cylinder 2 to move along a third direction z that is perpendicular to both the first direction x and the second direction y in response to the rotation of the handle 31.

[0040] Optionally, the mounting base 1 is the frame of a cigarette production device, such as the frame of a tipping machine.

[0041] Generally speaking, the glue applicator roller of a cigarette production device remains fixed relative to the mounting base 1, while the glue control roller is mounted on the glue cylinder 2. When applying glue to the tipping paper, the glue applicator roller and the glue control roller interact, and the glue in the glue cylinder 2 is transferred to the glue applicator roller through the glue control roller to apply glue to the tipping paper.

[0042] If the positions of the glue cylinder 2 relative to the mounting base 1 in both the first direction x and the second direction y reach the preset positions, then the glue cylinder 2 is installed in place; otherwise, the glue cylinder 2 is not installed in place, which will cause the position of the glue control roller relative to the glue applicator roller to shift, resulting in problems with the glue application quality.

[0043] Optionally, referring to Figure 1 , the adjusting mechanism includes a connecting frame 34. The connecting frame 34 has a first connection end and a second connection end. The first connection end is connected to the rotating shaft 33, and the second connection end is connected to the bracket 4. The handle 31, the rotating shaft 33, and the connecting frame 34 form a lever structure. As the handle 31 rotates, the rotating shaft 33 rotates about the second direction y and drives the connecting frame 34 and the bracket 4 to rotate about the second direction y. Therefore, under the action of the handle 31, the bracket 4 can move in the Figure 1 up and down direction (i.e., the third direction z) in

[0044] to lift or lower the glue cylinder 2. According to the specific structure of the glue cylinder assembly, the connecting frame 34 can be L-shaped, arc-shaped, or other shapes that can achieve the function of the bracket 4. Figure 1 Referring to Figure 5 , the third limiting portion 32 can rotate about the axis of the rotating shaft 33 in the xz plane as the handle 31 rotates. Referring to Figure 6, if the glue cylinder 2 is not properly installed, structural interference will occur between the third limiting part 32 and the glue cylinder 2 during rotation, restricting the continuous rotation of the third limiting part 32. Therefore, the third limiting part 32 can be used to detect whether the glue cylinder 2 is properly installed. The extension length of the third limiting part 32 along the second direction y towards the side of the handle 31 close to the glue cylinder 2 can be determined according to the specific structure of the glue cylinder assembly. For example, if the handle 31 is arranged radially along the rotation axis 33 and forms a gap with the glue cylinder 2 along the second direction y, the extension length can be set to be equal to the distance between the handle 31 and the glue cylinder 2 along the second direction y. The third limiting part 32 can be in the shape of a block, a plate, or other shapes that can achieve its own function.

[0045] In the glue cylinder assembly provided by the embodiments of the present disclosure, when an operator installs the glue cylinder 2 on the mounting base 1, the glue cylinder 2 can be positioned on the first limiting part 11 through the first positioning part 21 and positioned on the second limiting part 12 through the second positioning part 22, facilitating the installation of the glue cylinder 2 to a preset position. Moreover, the operator can detect whether the glue cylinder 2 is properly installed through the third limiting part 32 provided on the handle 31. Even if there is a certain deviation in the installation position of the glue cylinder 2, the position of the glue cylinder 2 along the third direction z can be adjusted by rotating the handle 31, so that the glue cylinder 2 is at least partially separated from the first limiting part 11 and the second limiting part 12, facilitating the re-positioning of the glue cylinder 2 relative to the first limiting part 11 and the second limiting part 12. It can be seen that through the above structural settings, the glue cylinder assembly of the embodiments of the present disclosure can reduce the risk of installation errors of the glue cylinder 2, and further reduce the risk of gluing quality problems.

[0046] The following further illustrates the relevant positioning structures and positioning methods for the positioning of the glue cylinder 2 on the mounting base 1 in some embodiments of the present disclosure with reference to the respective drawings.

[0047] In some embodiments, the first limiting part 11 and the first positioning part 21 form a pin positioning structure.

[0048] In some embodiments, the second limiting part 12 and the second positioning part 22 form a pin positioning structure.

[0049] In some embodiments, the first limiting part 11 and the first positioning part 21 form a pin positioning structure, and the second limiting part 12 and the second positioning part 22 form a pin positioning structure.

[0050] The pin positioning structure not only facilitates the installation of the glue cylinder 2 on the mounting base 1, but also facilitates the adjustment of the position of the glue cylinder 2 under the action of the handle 31, with a simple structure and low cost.

[0051] In some embodiments, refer to Figures 1 to 4, the first limiting portion 11 includes a first ejector pin, and the first positioning portion 21 is provided with a tapered hole 211 that cooperates with the first ejector pin.

[0052] In some embodiments, referring to Figures 1 to 4 , the second limiting portion 12 includes a second ejector pin, and the second positioning portion 22 is provided with a V-shaped groove 221 that cooperates with the second ejector pin.

[0053] In some embodiments, referring to Figures 1 to 4 , the first limiting portion 11 includes a first ejector pin, the first positioning portion 21 is provided with a tapered hole 211 that cooperates with the first ejector pin, the second limiting portion 12 includes a second ejector pin, and the second positioning portion 22 is provided with a V-shaped groove 221 that cooperates with the second ejector pin.

[0054] In the above embodiments, the ends of the first ejector pin and the second ejector pin have tapered surfaces. The tapered surface at the end of the first ejector pin cooperates with the tapered surface of the tapered hole 211, and the tapered surface at the end of the second ejector pin cooperates with the groove wall of the V-shaped groove.

[0055] Based on the cooperation between the first ejector pin and the tapered hole 211, the first limiting portion 11 can limit the degrees of freedom of movement of the glue cylinder 2 in the first direction x and the second direction y; based on the cooperation between the second ejector pin and the V-shaped groove, the second limiting portion 12 can further limit the rotational degree of freedom of the glue cylinder 2 in the third direction z. Based on this positioning method, under-positioning and over-positioning of the glue cylinder 2 can be prevented, ensuring the accuracy of the positioning of the glue cylinder 2.

[0056] In the above positioning method, the taper angle α of the tapered hole can be set to be smaller, and the opening angle β of the V-shaped groove can be set to be larger, so as to adjust the position of the glue cylinder 2 by rotating the handle 31 in the case where the glue cylinder 2 is not installed in place.

[0057] In some embodiments, referring to Figure 3 , the taper angle α of the tapered hole 211 is 90°.

[0058] In some embodiments, referring to Figure 4 , the opening angle β of the V-shaped groove 221 is 135°.

[0059] Some embodiments of the present disclosure further provide a cigarette production device, including the aforementioned glue cylinder assembly.

[0060] The cigarette production device provided by the embodiments of the present disclosure has the advantages of the glue cylinder assembly provided by the embodiments of the present disclosure.

[0061] In some embodiments, the cigarette production device is a cigarette making and tipping machine.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that modifications can still be made to the specific implementation manners of the present disclosure or equivalent replacements can be made to some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
