The pressing structure is mounted on the mounting plate, and the transport track is used to transport the cigarettes in a transport direction perpendicular to the cigarettes. The mounting plate and the transport track are fixed relative to each other.
[0018] As a preferred technical solution for the above-mentioned cigarette machine, it also includes a drive motor, the output end of which is connected to the rotating shaft via a transmission.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a pressing structure and a cigarette rolling machine. The adjusting component includes a flange and a first insertion part. The flange has multiple arc-shaped mounting holes around its axis, with the center of the flange as the center. The first insertion part is coaxially fixed to the flange. The adjusting component has a first insertion hole that passes through the first insertion part and the flange, with its axis parallel to the flange's axis. The first insertion part is inserted into a mounting plate and can rotate relative to it. The flange and mounting plate are connected by a first threaded fastener, which is inserted into the mounting hole and can rotate within it around the flange's axis. A rotating shaft is inserted into the first insertion hole and can rotate relative to the adjusting component. A pressing wheel is coaxially fixed to the rotating shaft and is used to press cigarettes onto a transport track. The mounting plate and the transport track are fixed relative to each other in a direction perpendicular to the cigarette's transport direction.
[0021] For example, the mounting plate has a second insertion hole and a third insertion hole, and multiple second insertion holes are formed around the axis of the third insertion hole. An adjusting component is mounted on the mounting plate. The adjusting component includes a flange portion and a first insertion portion. The third insertion hole is a circular hole, and the first insertion portion is a hollow cylinder. The first insertion portion is inserted into the third insertion hole and can rotate relative to the mounting plate around its own axis. The flange portion is coaxially fixed with the first insertion portion. The flange portion has multiple mounting holes, each corresponding to a multiple second insertion hole. The mounting holes are formed around the axis of the flange portion and are arc-shaped with the flange portion as the center. A first threaded fastener is inserted into the mounting holes and the second insertion holes. The adjusting component has a first insertion hole, the axis of which is parallel to the axis of the flange. That is, the first insertion hole is located at the eccentric position of the rotating axis of the adjusting component. The rotating shaft is inserted into the first insertion hole and can rotate relative to the adjusting component around its own axis. A pressure wheel is coaxially fixed to the rotating shaft, and the pressure wheel is spaced apart from the transport track.
[0022] During normal operation, the adjusting component is relatively fixed to the mounting plate via the first threaded fastener. Driven by the rotating shaft, the pressure wheel rotates relative to the adjusting component, and its outer circumferential arc presses the cigarettes onto the transport track. When it is necessary to adjust the gap between the pressure wheel and the transport track, loosen the first threaded fastener and rotate the adjusting component around the axis of the third insertion hole. Because the rotating shaft is inserted in an eccentric position, the distance between the pressure wheel and the transport track changes during the rotation of the adjusting component. Once the desired position is reached, retighten the first threaded fastener to lock the relative position of the adjusting component and the mounting plate.
[0023] In this way, the pressing structure can be adaptively adjusted according to the type of cigarette used in this operation to meet the operational requirements, improve the pressing quality, and expand its applicability. Attached Figure Description

[0043] like Figures 1 to 8As shown, this utility model provides a wire pressing structure 100, including an adjusting member 1, a rotating shaft 2, and a wire pressing wheel 3. The adjusting member 1 includes a flange portion 11 and a first insertion portion 12. The flange portion 11 has multiple mounting holes 111 around its axis, each hole being arc-shaped and centered on the center of the flange portion 11. The first insertion portion 12 is coaxially fixed to the flange portion 11. The adjusting member 1 has a first insertion hole 101 that penetrates both the first insertion portion 12 and the flange portion 11. The axis of the first insertion hole 101 is parallel to the axis of the flange portion 11. The first insertion portion 12 is inserted into a mounting plate 200 and can... The flange 11 is rotatable relative to the mounting plate 200. The flange 11 is connected to the mounting plate 200 by a first threaded fastener 13. The first threaded fastener 13 is inserted into the mounting hole 111 and can rotate around the axis of the flange 11 within the mounting hole 111. The rotating shaft 2 is inserted into the first insertion hole 101 and can rotate relative to the adjusting member 1. The pressing wheel 3 is coaxially fixed with the rotating shaft 2. The pressing wheel 3 is used to press the cigarette 400 on the transport track 300. The mounting plate 200 and the transport track 300 are fixed relative to each other in the transport direction perpendicular to the cigarette 400.
[0044] For example, the mounting plate 200 has a second insertion hole 201 and a third insertion hole 202. Multiple second insertion holes 201 are formed around the axis of the third insertion hole 202. An adjusting member 1 is mounted on the mounting plate 200. The adjusting member 1 includes a flange portion 11 and a first insertion portion 12. The third insertion hole 202 is a circular hole. The first insertion portion 12 is a hollow cylinder and is inserted into the third insertion hole 202. The first insertion portion 12 can rotate relative to the mounting plate 200 around its own axis. The flange portion 11 is coaxially fixed with the first insertion portion 12. The flange portion 11 has multiple mounting holes 111, each corresponding to a different second insertion hole 201. The mounting holes 111 are formed around the axis of the flange portion 11 and are arc-shaped with the flange portion 11 as the center. A first threaded fastener 13 is inserted into the mounting holes 111 and the second insertion holes 201. The adjusting component 1 has a first insertion hole 101. The axis of the first insertion hole 101 is parallel to the axis of the flange part 11. That is, the first insertion hole 101 is opened at an eccentric position on the rotation axis of the adjusting component 1. The rotating shaft 2 is inserted into the first insertion hole 101. The rotating shaft 2 can rotate relative to the adjusting component 1 around its own axis. The rotating shaft 2 is coaxially fixed with a pressure wheel 3. The pressure wheel 3 is spaced apart from the transport track 300.
[0045] During normal operation, the adjusting component 1 is relatively fixed to the mounting plate 200 by the first threaded fastener 13. The pressing wheel 3 rotates relative to the adjusting component 1 under the drive of the rotating shaft 2, and the outer circumferential arc of the pressing wheel 3 presses the cigarette 400 on the transport track 300. When it is necessary to adjust the gap between the pressing wheel 3 and the transport track 300, loosen the first threaded fastener 13 and rotate the adjusting component 1 around the axis of the third insertion hole 202. Since the rotating shaft 2 is inserted in an eccentric position, the distance between the pressing wheel 3 and the transport track 300 changes accordingly during the rotation of the adjusting component 1. After reaching the designated position, tighten the first threaded fastener 13 again to lock the relative position of the adjusting component 1 and the mounting plate 200.
[0046] In this way, the compression structure 100 can be adaptively adjusted according to the 400 types of cigarettes used in this operation to meet the operational requirements, improve the compression quality, and expand its applicability.
[0047] Furthermore, the second insertion hole 201 is a threaded hole, and the first threaded fastener 13 is threadedly connected to the mounting plate 200 within the second insertion hole 201.
[0048] Furthermore, the second insertion hole 201 is a smooth hole, and the first threaded fastener 13 passes through the second insertion hole 201 and is threadedly connected to the nut.
[0049] Optionally, the mounting hole 111 is a countersunk hole, and the nut of the first threaded fastener 13 can be inserted into the mounting hole 111.
[0050] For example, the mounting hole 111 is a countersunk hole, that is, the mounting hole 111 includes a large diameter section and a small diameter section. The large diameter section is formed on the side of the flange portion 11 facing away from the mounting plate 200. The screw of the first threaded fastener 13 is inserted into the small diameter section of the mounting hole 111 and the second insertion hole 201 of the mounting plate 200. The nut of the first threaded fastener 13 can be inserted into the large diameter section of the mounting hole 111.
[0051] Optionally, multiple pressing rollers 3 are provided, and the multiple pressing rollers 3 are fixed coaxially. With this configuration, the pressing structure 100 can perform pressing operations on multiple rows of cigarettes 400 on the transport track 300, thereby improving work efficiency.
[0052] Optionally, the rotating shaft 2 and the pressure roller 3 are fixed by a plurality of second threaded fasteners 21.
[0053] For example, the axial end face of the rotating shaft 2 is provided with a plurality of fifth insertion holes 22, and the axial end face of the pressure wheel 3 is provided with a plurality of fourth insertion holes 31. The plurality of fourth insertion holes 31 correspond one-to-one with the plurality of fifth insertion holes 22. The second threaded fastener 21 is inserted into the fourth insertion hole 31 and the fifth insertion hole 22, and is threadedly connected to the rotating shaft 2 in the fifth insertion hole 22.
[0054] Preferably, the plurality of fifth insertion holes 22 are distributed around the axis of the rotation shaft 2.
[0055] Optionally, the wire pressing structure 100 may also include a first bearing 41, the inner ring of which is sleeved on the rotating shaft 2, and the outer ring of which is fixed to the first insertion part 12.
[0056] For example, when the equipment is operating normally, the adjusting member 1 and the mounting plate 200 are in a fixed state, while the rotating shaft 2 drives the pressing wheel 3 to rotate. The first bearing 41 can reduce the friction when the rotating shaft 2 and the adjusting member 1 rotate relative to each other.
[0057] Optionally, the adjusting member 1 further includes a second insertion part 14, which is located on the side of the flange part 11 opposite to the first insertion part 12 and is coaxially fixed with the flange part 11. The first insertion hole 101 passes through the second insertion part 14. In this way, the support for the rotating shaft 2 can be extended, and the sway of the rotating shaft 2 when driving the pressure roller 3 to rotate can be reduced.
[0058] Optionally, the pressure roller 3 is sleeved outside the second insertion portion 14 and spaced apart from the second insertion portion 14. In this way, the axial dimension of the pressure roller 3 of the pressure structure 100 can be reduced.
[0059] Optionally, the wire pressing structure 100 also includes a second bearing 42, the inner ring of which is sleeved on the rotating shaft 2, and the outer ring of which is inserted into and fixed to the second insertion part 14. The second bearing 42 can reduce the friction when the rotating shaft 2 and the adjusting member 1 rotate relative to each other.
[0060] A cigarette rolling machine is also provided, including a mounting plate 200, a transport track 300, and the aforementioned pressing structure 100. The pressing structure 100 is mounted on the mounting plate 200, and the transport track 300 is used to transport cigarettes 400. The mounting plate 200 and the transport track 300 are fixed relative to each other in a transport direction perpendicular to the cigarettes 400.
[0061] Optionally, the cigarette making machine also includes a drive motor, the output end of which is connected to the rotating shaft 2 via a transmission.
[0062] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
