[0002] In the process of recycling defective cigarettes, for composite filter rod cigarettes containing powder flavors and bursting beads in the filter rod, it is usually necessary to separate the filter rods of composite filter rod cigarettes through a cigarette filter rod separator before they can be recycled. The cigarette filter rod separator mainly supplies cigarettes in the silo to the negative pressure drum wheel, arranges the cigarettes one by one in the smoke settling tank of the negative pressure drum wheel, and separates them on the drum wheel by breaking or shearing. During the shutdown and startup of the cigarette filter rod separator, the drum wheel needs to be reversed for reset, or when a failure occurs, the drum wheel needs to be manually turned and reversed. The cigarettes are tightly fitted in the smoke settling tank under the action of negative pressure. When the drum wheel reverses, the cigarettes will be stuck at the joint between the silo plate and the drum wheel, affecting the normal operation of the equipment. At the same time, during the normal operation of the cigarette filter rod separator, the filter rod of the cigarette is cantilevered on the drum wheel to extend a filter rod length, and some deformed cigarettes will deviate from the position of the smoke settling tank, causing the equipment to be stuck.

[0022] like Figure 1-4As shown, the anti-blocking device of the cigarette filter rod separator comprises: a cigarette taking block 1, an arc support frame 2 and a drum wheel 3. The cigarette taking block 1 is provided with a third shovel tooth 11, a first shovel tooth 12, a second shovel tooth 13, a concave arc surface 14, a waist hole 15, a first threaded hole 16 and a second threaded hole 17. The third shovel tooth 11, the first shovel tooth 12 and the second shovel tooth 13 are tangent to the concave arc surface 14 respectively. The third shovel tooth 11 fits with the arc support frame 2 and is screwed through the through hole 21 of the support frame 2 to cooperate with the second threaded hole 17, thereby fixing the arc support frame 2 on the cigarette taking block 1. The arc surface 14 is connected with the silo plate 4 of the filter rod separator and is screwed through the through hole on the silo plate 4 to cooperate with the first threaded hole 16 to fix the cigarette taking block 1 and the silo plate 4. The screw passes through the waist hole 15 to cooperate with the threaded hole of the filter rod separator frame 7 to fix the cigarette taking block 1 on the filter rod separator.

[0023] A deep smoke extraction groove 31 is provided in the middle of the drum wheel 3, the first shovel tooth 12 is placed in the smoke extraction groove 31, and the two second shovel teeth 13 are respectively placed in the two original smoke compression grooves 32 of the drum wheel 3. The arc surface of the arc support frame 2 is tangent to the bottom of the plurality of smoke sinking grooves 33 on the drum wheel 3.

[0024] When the cigarette filter rod separator is working normally, there is negative pressure in the smoke settling groove 33 of the drum wheel 3, and the cigarette 6 will be adsorbed in the smoke settling groove 33. When the drum wheel 3 is reversed and reset or the drum wheel is manually reversed, the cigarette 6 first contacts the longer first shovel tooth 12, and the cigarette 6 is taken away from the bottom of the smoke settling groove 33 by the first shovel tooth 12. Then, after the cigarette 6 contacts the third shovel tooth 11 and the second shovel tooth 13, the cigarette 6 smoothly leaves the drum wheel 3 along the shovel teeth. After leaving the shovel teeth, the cigarette 6 moves smoothly in the concave arc surface 14 to the silo plate 4 and is then recovered into the cigarette silo 5, which effectively avoids the cigarette 6 from being stuck at the joint between the drum wheel 3 and the silo plate 4. The cigarette 6 is cantilevered on the drum 3 to extend out by the length of a filter rod. If the cigarette 6 is deformed too much during the movement with the drum 3, it will deviate from the cigarette collecting groove 33. The arc surface of the arc support frame 2 is tangent to the bottom of several cigarette collecting grooves 33 on the drum 3, which can stably support the cigarette 6 to rotate with the drum 3, avoiding the deviation of the position of the cigarette 6 and causing blockage of the equipment.

[0025] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
