Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a longitudinal position adjustment mechanism of a glue cylinder of a cigarette making machine, a tipping paper gluing device and a cigarette making machine. Background Technique

[0002] In cigarette production, the uniformity of tipping paper gluing and the distribution of the glue area are controlled by the glue cylinder. The bent arm is the bearing and positioning device of the glue cylinder. The longitudinal position of the bent arm, that is, the axial position of the glue cylinder, directly affects the distribution of the longitudinal glue area position of the cigarette tipping paper. If the longitudinal glue area position of the cigarette tipping paper is offset, it will affect physical indexes such as the "draw resistance" of the cigarette, and will also cause appearance problems such as "tipping paper edge warping". At the same time, the incorrect glue area will also cause glue accumulation on the drum of the tipping machine, affecting the normal production of the equipment.

[0003] In current production, when the operator finds that the glue area position of the cigarette tipping paper is abnormal, they need to stop the machine immediately, then judge the offset direction of the glue area, and adjust the bent arm in or out by loosening or tightening the positioning nut on the left side of the bent arm with a wrench. Then restart the equipment to observe the longitudinal distribution of the glue area. If there is still an offset, the above adjustment steps need to be repeated. This adjustment method of judging the longitudinal position of the bent arm based on personal experience needs to be carried out at least two to three times to completely correct the glue area distribution position.

[0004] In the prior art, Chinese Patent CN202120563308.2 discloses a device for online adjusting the offset of the glue position of the cigarette filter tipping paper without stopping the machine. By combining a handle with a gear drive to rotate the adjusting nut, the axial position of the glue cylinder can be adjusted outside the machine without stopping the machine. However, its scheme is essentially still rotating the adjusting nut of the original machine, with low efficiency. And its use of gear drive has limited self-locking and accuracy. Therefore, providing a better adjustment scheme for the axial position of the glue cylinder of a cigarette making machine is an urgent technical problem to be solved in the field.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] For the axial position adjustment mechanism of the glue cylinder of the cigarette making machine in this application, please refer to the attached Figure 1-2 , which includes an elbow arm 2 configured to install and position the glue cylinder 200; and a mounting rod 3 arranged parallel to the axis of the glue cylinder 200; and a transmission member 4 movably arranged on the mounting rod 3; the transmission member 4 is in transmission connection with the elbow arm 2 and is configured to drive the elbow arm 2 to move along the mounting rod 3; the axial position adjustment mechanism of the glue cylinder of the cigarette making machine further includes a driving member 5 configured to drive the transmission member 4 and / or the mounting rod 3.

[0026] By arranging the elbow arm 2 on the mounting rod 3 and the transmission member 4, in addition to the installation of the elbow arm 2 and the transmission member 4, the mounting rod 3 also plays a guiding role in the movement of the elbow arm 2 along the axial position of the glue cylinder 200, and the efficiency of position adjustment is relatively high.

[0027] In some embodiments, the elbow arm 2 includes a mounting hole and is sleeved on the mounting rod 3 through the mounting hole. Compared with the prior art method of adjusting the position of the elbow arm 2 by rotating an adjusting nut, directly arranging the elbow arm 2 on the mounting rod 3 through the mounting hole can increase the contact area, make the installation of the elbow arm 2 and the adjustment and determination of its position more stable, and can also simplify the transmission link and improve the efficiency.

[0028] In some embodiments, the mounting rod 3 is a screw rod, and the transmission member 4 is a threaded sleeve, and the screw rod is rotatably arranged on the machine shell 1. When the screw rod rotates, since the threaded sleeve is connected to the elbow arm, the threaded sleeve does not rotate with the screw rod, but moves along the length direction of the screw rod, that is, the axis of the glue cylinder 200, and drives the elbow arm 2 connected to the threaded sleeve to move along the axis of the glue cylinder 200. Screw drive has higher efficiency at small stroke and lower rotational speed, has higher positioning accuracy, can provide more precise linear motion control, and conforms to the application scenario of the mechanism provided in this application. Screw drive also has a self-locking characteristic, which can be used to reduce the accidental movement of the elbow arm 2 and reduce the frequency of adjusting the position.

The implementation manner of the operating member is not limited, as long as it can drive the transmission member 4 to move or stop moving according to the operation on it by the driving member 5, for example, it is set as a button electrically connected to the driving member 5, or set as a handle or a knob in transmission connection with the driving member 5.

[0031] In some embodiments, the axial position adjusting mechanism of the cigarette machine glue cylinder includes a machine housing 1, the operating member includes a manual dial, and the machine housing 1 is provided with a through hole for the manual dial to pass through. Using the manual dial as the operating member is relatively easy to implement, easy to pass through the machine housing 1, and the modification of the original machine housing 1 is small.

[0032] In some embodiments, arranging the screw rod in the machine housing 1 can make full use of the original machine structure. Driving the screw rod to rotate and cooperating with the sleeve to convert the rotation into linear motion is relatively stable and efficient, and easy to implement.

[0033] In some embodiments, the driving member 5 includes a first gear fixedly arranged coaxially with the manual dial, and the mounting rod 3 is provided with a second gear meshing with the first gear. Turning the manual dial can make the mounting rod 3 rotate through the gears.

[0034] In some embodiments, the radius of the first gear is smaller than that of the second gear. So as to save effort when turning the manual dial.

[0035] The present application also provides a tipping paper gluing device, including the axial position adjusting mechanism of the cigarette machine glue cylinder, so it has all its beneficial effects.
