[0002] During the production process of the cigarette making machine, whether it is an active manual shutdown or a passive shutdown due to a fault, or the equipment is restarted after shutdown, it will inevitably produce waste tobacco, mainly long tobacco rods wrapped in coil paper. The current methods for processing such long tobacco rods include manual cutting, online or offline machine cutting, or after rehumidification, rubbing and impacting the long tobacco rods through waste tobacco processing equipment to separate the tobacco from the long tobacco rods. However, the above separation methods will inevitably cause some of the tobacco to break, greatly reducing the whole tobacco rate and the output rate of the recycled tobacco. In the end, the recycled tobacco can only be downgraded for use, and cannot be directly blended with the same cigarette brand, which increases production material consumption and labor costs.

[0020] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] Embodiment 1:
[0022] like Figure 1-2 As shown, an embodiment of the utility model provides an online pre-cutting and separating device for long cigarette rods, comprising a retractable cutter unit 1 arranged at a position before the cigarette enters a cigarette gun 8 and a control unit 2 for controlling the retraction of the cutter unit 1. The cutter unit 1 is arranged below the cigarette paper travel path in the existing long cigarette rod preparation device. The cutter unit 1 is aligned with the middle of the cigarette paper travel path so that an incision is formed in the middle of the normal cigarette paper 6.
[0023] In this embodiment, the cutter unit 1 includes a cutter, and the control unit 2 includes an electromagnet 21, an armature 22 and a frame 23. The frame 23 includes a fixed part and a movable part, and a walking path for cigarette paper to pass through is formed between the fixed part and the movable part. The electromagnet 21 is installed on the fixed part, the armature 22 is fixed on the movable part, and the cutter is fixed on the armature 22. The electromagnet 21 absorbs the armature 22 to achieve cutting of normal cigarette paper 6 by the cutter. The pre-divided cigarette paper 7 will naturally separate from the cigarette paper due to the presence of the incision in the subsequent cigarette rolling process. After the pre-divided cigarette paper 7 enters the cigarette gun, it is wrapped by the running cloth belt, and the incision is located at the bottom relative to the cloth belt, so it will not affect the forming action of the overlap of the cigarette rod.
[0024] In this embodiment, the control unit 2 is effectively electrically connected to the control system of the first soldering iron 3 in the existing long tobacco rod preparation device. The control unit 1 is effectively electrically connected to the control system of the tobacco rod making device 4 in the existing long tobacco rod preparation device.
[0025] In this embodiment, during the start-up phase of the device (existing long tobacco rod preparation device), the speed must reach 1000 cigarettes / minute, and the start-up program controls the first soldering iron 3 to descend to heat and solidify the tobacco rods, so the tobacco rods produced before cannot be regarded as qualified products. The action of the electromagnet 21 is the same as Figure 2 The action of the first soldering iron 3 is synchronized, that is, before the first soldering iron 3 descends, under the action of the large pressure plate, the long tobacco rod produced has been overlapped normally, but the bottom has been pre-cut, so the tobacco and cigarette paper can be naturally separated. After the first soldering iron 3 descends, the electromagnet 21 releases the armature, and the cutter unit 1 stops cutting the cigarette paper. When the operator observes that the complete tobacco rod has reached the position of the rod maker 4, the tobacco rod is manually beaten to allow it to enter the microwave measuring tube normally, completing the normal startup and operation of the equipment. In this way, in the startup stage of the equipment, it is theoretically possible to achieve long tobacco rods without tobacco wrapped by coil paper.
[0026] In this embodiment, during the shutdown phase of the equipment (existing long tobacco rod preparation device), if the automatic machine stops due to any fault or the machine stops manually, the shutdown signal will control the rod breaker 4 to break the long tobacco rod in operation. The broken tobacco rod will enter the waste bin under the action of gravity. Affected by the inertia of the equipment, it takes 3 to 6 seconds for the equipment to stop completely. Therefore, the tobacco rods produced during this period cannot be regarded as qualified products. The action of the electromagnet 21 is consistent with the Figure 2 The middle tobacco rod maker 4 operates synchronously, that is, when the stop signal switches the tobacco rod maker 4 to the non-working position, the cutter unit 1 immediately cuts the cigarette paper, thereby minimizing the generation of long tobacco rods wrapped by the coil paper.
[0027] Embodiment 2:
[0028] The difference between this embodiment and embodiment 1 is that: the cutter unit 1 includes a cutter, the control unit 2 includes a cylinder, the cutter is installed at the end of the cylinder, and the extension and retraction of the cylinder drives the cutter to extend and retract, thereby realizing that the cutter selectively cuts the cigarette paper, and the cutter unit 1 also includes a paper edge adjustment plate 11 with a cutting groove arranged on one side of the cutter, and the paper edge adjustment plate 11 is used to control the front and rear position of the cigarette paper relative to the cigarette gun 8, thereby controlling the position of the glue spraying line relative to the overlap of the cigarette, and preventing the generation of "non-overlap" defective products. The rest of the structure is the same as that of embodiment 1.
[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
