Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a multi-specification automatic blowing device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Cigarettes are mainly produced by automated assembly lines. During production, cigarettes are subject to clamping, transportation, grabbing and other actions from the equipment, which can easily cause the cigarettes to be damaged and become defective. Another part of the cigarettes will become defective due to process problems that do not meet factory standards. In order to save costs, the tobacco in defective cigarettes can be recycled for a second time. The current traditional practice is to cut the defective cigarettes and then screen them through vibration, impact or collision to separate the tobacco from the cigarette paper. Although this method has a simple process and can handle a large number of cigarettes, the cigarette paper will be wasted after it is broken, making it easy for the recycled tobacco to contain broken cigarette paper. In addition, the tobacco contains more broken tobacco after physical impact, resulting in a decline in quality. Utility Model Content

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] It should be noted that the following detailed descriptions are exemplary and are intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] As introduced in the background technology, although the traditional method of recycling tobacco from cigarettes has a simple process and can process a large number of cigarettes, the formed cigarette tubes will be wasted after the cigarette paper is broken, making it easy for the recycled tobacco to contain broken cigarette paper, and the tobacco will contain more broken tobacco after physical impact, resulting in a decline in quality.

[0031] Therefore, the following embodiment provides a multi-specification automatic tobacco blowing device, which enables tobacco shreds and cigarette paper in cigarettes of various specifications to be separated and recovered by blowing, and the recovered tobacco shreds do not contain cigarette paper and have better integrity.

[0032] like Figure 1-Figure 4 As shown, a multi-specification automatic wire blowing device comprises:

[0033] The silo is used to store the cigarettes to be blown and drop them into the loading and unloading unit by gravity;

[0034] The loading and unloading unit comprises a loading mechanism and a receiving mechanism. The loading mechanism comprises a roller, and at least one group of grooves are arranged on the surface of the roller in the axial direction, and the diameters of different grooves are different; the receiving mechanism comprises a turntable, and a plurality of groups of grooves are evenly arranged on the surface of the turntable in the axial direction, and one end of the groove faces the inlet of the recovery pipeline, and the outlet of the recovery pipeline is connected to the tobacco collection device;

[0035] The clamping mechanism includes a clamping seat moving in a vertical direction, a clamping block driven by a clamping power module is provided on the clamping seat, a plurality of clamping holes arranged in a vertical direction are provided on the clamping block, and the clamping holes have different diameters. One side of the clamping hole faces one end of a groove on the surface of the turntable, and the other side is provided with a wire blowing module moving in a horizontal direction.

[0036] like Figure 1 As shown, the silo 1, the loading and unloading unit and the clamping mechanism are all fixed on the base. The cigarettes are stored in the silo 1 and fall down by their own weight. The bottom of the silo 1 is provided with a cigarette outlet, allowing the cigarettes to fall into the loading and unloading unit from the outlet. The loading and unloading unit transfers the tobacco to the required position, which is clamped and fixed by the clamping mechanism. Compressed gas is blown into one end of the cigarette to separate the tobacco inside the cigarette from the cigarette paper, and then enter the tobacco collection device 6. The empty cigarette paper is driven by the loading and unloading unit to be sent to the cigarette collection device 8 to complete the blown tobacco recovery.

[0037] like Figure 2 As shown, the loading and unloading unit includes a loading mechanism 2 and a receiving mechanism 3. The loading mechanism 2 includes a roller driven by a power module and rotated. At least one group of grooves are provided on the surface of the roller along the axial direction. Different grooves have different diameters and are used to receive and accommodate cigarettes of different specifications from the silo 1.

[0038] The receiving mechanism 3 includes a turntable driven by the power module and rotated along with the feeding mechanism 2, and a plurality of grooves are evenly arranged on the surface of the turntable along the axial direction, for receiving and accommodating the cigarettes delivered from the feeding mechanism 2. One end of the groove faces the inlet of the recovery pipeline, and the outlet of the recovery pipeline is connected to the tobacco collection device 6.

[0039] In this embodiment, the power module is a motor, and the corresponding motor drives the feeding mechanism 2 and the receiving mechanism 3 to rotate, so that the cigarettes are transported from the silo 1 to the receiving mechanism 3 through the feeding mechanism 2. The surface of the roller of the feeding mechanism 2 is provided with grooves of various diameters for handling the feeding of cigarettes of various specifications (three in this embodiment). The specification switching uses a quick-change connection block 21 with a magnetic strip, and the structure is as follows: Figure 3 As shown, when different specifications need to be changed, the other grooves are blocked by using the quick-change connection block 21, and only the grooves of the currently required specifications are retained as the loading position to achieve quick change.

[0040] like Figure 1As shown, the loading and unloading unit also includes a positioning mechanism 4, which includes a push plate connected to the movable end of the cylinder. The cylinder drives the push plate to move along the axial direction of the turntable on the turntable surface of the material receiving mechanism 3, pushing one end of the cigarette so that the other end of the cigarette enters the clamping mechanism 5.

[0041] The loading and unloading unit also includes a discharge plate 7, which is arranged at an angle, with the higher part close to the turntable surface of the material receiving mechanism 3, and the lower part is provided with a cigarette collecting device 8. After the cigarette is blown, it is transported to the discharge plate 7 under the drive of the material receiving mechanism 3, and falls into the cigarette collecting device 8 for recovery.

[0042] like Figure 4 As shown, the clamping mechanism 5 includes a lifting track 51 arranged in the vertical direction and a clamping seat 52 slidably connected to the lifting track 51. The clamping seat 52 is provided with a clamping power module (a clamping cylinder 53 in this embodiment), and the clamping power module drives the clamping blocks 54 to move closer to or away from each other.

[0043] The clamping block 54 is provided with a plurality of clamping holes arranged in a vertical direction. The diameters of the clamping holes are different and are used to clamp cigarettes of different specifications. One side of the clamping hole faces one end of the groove on the surface of the turntable in the material receiving mechanism 3, and the other side of the clamping hole is provided with a blowing module 55 that moves in a horizontal direction.

[0044] In this embodiment, the required clamping holes are adjusted to correspond to the positions of the turntable grooves by vertically moving the clamping seat 52 along the lifting track 51 .

[0045] The blowing module 55 includes a gas nozzle, one end of a pipeline is connected to the gas nozzle, and the other end is connected to a gas storage tank via a control valve. The gas storage tank is connected to a gas compressor via a pipeline. The gas compressor provides compressed gas. The control valve is opened to blow the compressed gas from the gas nozzle toward the clamping hole, so that the tobacco in the clamped cigarette is blown out. In this embodiment, the pipeline part of the compressed gas is not drawn.

[0046] The cigarette is transferred to the groove of the turntable of the receiving mechanism 3 by the feeding mechanism 2. The cylinder of the positioning mechanism 4 pushes one end of the cigarette so that the other end of the cigarette enters the clamping hole of the clamping block 54. The clamping power module (clamping cylinder 53) drives the clamping block 54 to clamp the cigarette. At this time, one end of the groove on the surface of the turntable faces the inlet of the recovery pipeline. The outlet of the recovery pipeline is connected to the tobacco collection device 6. The blowing module 55 moves in the horizontal direction so that the air nozzle extends into the clamping hole and approaches one end of the cigarette. The air nozzle in the clamping hole blows out compressed gas to blow the tobacco in the cigarette into the tobacco collection device 6 along the recovery pipeline. During this period, the cigarette body is still accommodated by the groove on the surface of the turntable, and only one end is clamped. After the clamping mechanism 5 releases the clamping state, as the turntable continues to rotate, the cigarette that has been blown (at this time, it is already in the state of a cigarette paper tube) falls into the cigarette collection device 8 through the discharge plate 7, completing the separation and recovery of tobacco and cigarette paper.

[0047] In this embodiment, the clamping force provided by the clamping cylinder 53 is sufficient to ensure that the cigarette will not be blown out of the turntable groove by the compressed gas.

[0048] Through the device of the above structure, tobacco shreds and cigarette papers in cigarettes of various specifications can be separated by blowing, and the recovered tobacco shreds do not contain cigarette papers and have better integrity.

[0049] The working method of the above-mentioned multi-specification automatic wire blowing device comprises the following steps:

[0050] Cigarettes fall from the cigarette outlet at the bottom of the silo 1 into the feeding mechanism 2, which transfers the cigarettes to the turntable groove of the receiving mechanism 3;

[0051] The cylinder of the positioning mechanism 4 moves to push one end of the cigarette, so that the other end of the cigarette enters the clamping hole, and the clamping power module drives the clamping block 54 to clamp the cigarette;

[0052] The blowing module 55 moves in the horizontal direction so that the air nozzle extends into the clamping hole and approaches one end of the cigarette;

[0053] The air nozzle in the clamping hole blows out compressed gas to blow the tobacco in the cigarette along the recovery pipeline into the tobacco collection device 6;

[0054] After the blowing is completed, the clamping mechanism 5 releases the clamping state, and as the turntable continues to rotate, the cigarettes that have been blown fall into the cigarette collecting device 8 through the discharge plate 7, completing the separation and recovery of the tobacco and cigarette paper.

[0055] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
