Description

Technical Field

[0001] This invention relates to the field of waste cigarette processing tobacco recycling technology, specifically, to a method for recycling and processing waste cigarettes containing filter tip particle additives. Background Technology

[0002] Currently, the recycling and processing of waste cigarettes generally employs a stirring and separation method. This involves using agitator rollers to break down the cigarettes, followed by a vibrating screen to separate the tobacco from the filter and cigarette paper. However, this method is unsuitable for cigarettes with filter tips containing particulate additives. During the stirring process, these additives are incorporated into the tobacco, and because the particles are small, they cannot be effectively separated during the subsequent sieving process. Furthermore, the stirring and separation method results in significant tobacco breakage, and the resulting waste paper often contains tobacco fragments, leading to tobacco waste. Existing technologies include cutting to remove the filter before using a stirring and separation method to separate the tobacco from the cigarette paper. This method also introduces added particulate matter into the cigarettes during the cutting process. Therefore, a recycling and processing method specifically for cigarettes containing filter-added particulate matter is needed to improve the quality of tobacco recycling while addressing the issue of particulate matter contamination. Summary of the Invention

[0003] To address at least one aspect of the aforementioned problems, the present invention provides a method for recycling waste cigarettes containing filter tip particles. This method involves first making an incomplete break at the connection between the filter tip rod and the unfiltered cigarette, then bending the filter tip rod relative to the unfiltered cigarette along the break, and finally cutting the remaining cigarette paper connecting the filter tip rod and the unfiltered cigarette. This avoids the risk of fibers and particles from the filter tip rod being mixed into the tobacco by directly cutting the filter tip, thereby improving the quality of tobacco recycling.

[0004] This application is achieved through the following technical solution: a method for recycling and processing waste cigarettes containing filter particulate additives, comprising the following steps:

[0005] The steps for loading waste cigarettes onto the drum are as follows: Several waste cigarettes to be recycled are sequentially transferred to the cigarette holding trough of the negative pressure drum, and the filter rods of the waste cigarettes are suspended from the negative pressure roller.

[0006] Steps for cutting and breaking off waste cigarettes: A first blade is provided on the side of the negative pressure drum, so that a break-off is cut at the connection line between the filter rod and the cigarette without a mouthpiece during the rotation of the negative pressure drum.

[0007] Waste cigarette bending steps: A guide device is set on the side of the negative pressure drum above the first blade. The guide device applies a force to the filter rod in the opposite direction of the movement of the negative pressure drum, so that the filter rod and the cigarette without a mouthpiece are bent along the break.

[0008] Waste cigarette cutting steps: The guide device applies a force to the filter rod in a direction different from the movement direction of the negative pressure drum, cutting the unbroken cigarette paper between the bent filter rod and the cigarette without a mouthpiece, and the filter rod falls into the first collection box.

[0009] Steps for removing a cigarette without a mouthpiece: Remove the cigarette without a mouthpiece from the negative pressure drum;

[0010] Cutting steps for cigarettes without a filter tip: Use the second blade to cut only the cigarette paper on the surface of the cigarette without a filter tip, so that the cigarette paper is spread out;

[0011] Separation steps for cigarette paper and tobacco: Separate cigarette paper and tobacco. The cigarette paper falls into the first collection box or the second collection box, and the tobacco falls into the tobacco recycling box.

[0012] Preferably, the depth of the break is within the range of the cigarette's diameter. .

[0013] Preferably, a waste cigarette combing step is provided before the step of loading waste cigarettes onto the drum, and the waste cigarette combing step includes the following steps:

[0014] Step 1: The waste cigarettes to be recycled are fed into a vibrating device, which vibrates the waste cigarettes evenly and then transfers them to a combing device.

[0015] Step 2: Use a combing device to comb several waste cigarettes into the same direction and transfer them to a cigarette transfer device connected to a negative pressure drum.

[0016] Preferably, in step 2, the length direction of the combed waste cigarettes is the same as the direction of waste cigarette transport.

[0017] Preferably, the step of loading waste cigarettes onto the drum wheel includes the following steps:

[0018] Step 1: Use a cigarette transfer device to sequentially transfer several waste cigarettes to the cigarette holding slot of the negative pressure drum, and make one end of the waste cigarettes suspend out of the negative pressure drum;

[0019] Step 2: Use a color mark detection device to detect and determine whether the end of the negative pressure drum that is suspended is the filter rod end or the ignition end;

[0020] Step 3: A blowing device is installed on one side of the negative pressure drum. When the result determined in Step 2 is the ignition end, the blowing device is activated to blow the waste cigarette toward the other side of the negative pressure drum, and the filter rod of the waste cigarette is suspended.

[0021] Preferably, there are two first blades, which are respectively installed on both sides of the negative pressure drum and arranged symmetrically.

[0022] Preferably, in the cigarette removal step, a cigarette removal device is used to remove the cigarette from the negative pressure drum and place it in a cutting device.

[0023] Preferably, a clamping device is provided directly above the cutting point of the cutting device.

[0024] Preferably, a negative pressure separation device is used in the cigarette paper and tobacco shred separation step. The negative pressure separation device is installed above the cutting device and uses negative pressure to adsorb the cigarette paper and transfer it to the first collection box or the second collection box, while the tobacco shreds fall into the tobacco shred recycling box.

[0025] The present invention provides a method for recycling and processing waste cigarettes containing filter tip particles, which has the following beneficial effects:

[0026] (1) By first cutting an uncut break at the connection between the filter rod of the waste cigarette and the cigarette without a filter, then bending the filter rod relative to the cigarette without a filter along the break, and then cutting the cigarette paper at the remaining connection between the filter rod and the cigarette without a filter, the method of manually separating the filter rod is simulated, avoiding the risk of fiber and particulate matter in the filter rod being mixed into the tobacco by directly cutting the filter, thereby improving the recycling quality of the tobacco.

[0027] (2) By selecting the cutting method to cut only the cigarette paper, the integrity of the tobacco can be guaranteed to the greatest extent, avoiding the large amount of breakage caused by the stirring and separation method, which helps to improve the recycling quality of tobacco.

[0028] (3) The fully automated recycling of waste cigarettes is achieved by a series of interconnected vibration devices, combing devices, cigarette transfer devices, negative pressure drums, extraction devices, cutting devices and negative pressure separation devices, which helps to improve the processing efficiency of waste cigarettes.
