Description

Technical Field

[0001] This invention relates to the field of defective cigarette processing in the cigarette industry, specifically to an automatic screening and processing device for defective cigarettes with double-layered paper and unwrapped paper sections. Background Technology

[0002] Existing automatic cigarette sorting and filter / cigarette cutting and separation devices can screen out cigarette residue, including tobacco dust, filters, cigarettes, and water paper, and remove the whole cigarette.

[0003] However, the above-mentioned device cannot screen defective cigarettes with double water paper or water paper that is not fully wrapped. The screening can only be done manually, which means that the automatic material handling and filter cigarette cutting and separation device for removing defective cigarettes cannot achieve complete automation of defective cigarette removal.

[0004] The purpose of this invention is to solve the problem of automatic screening and processing of cigarettes with double-layered paper and unwrapped paper sections, so as to realize the automation of automatic material handling for removing defective cigarettes and the automatic cutting and separation device for filter cigarettes. Summary of the Invention

[0005] To overcome the above problems, this application provides an automatic screening and processing device for cigarettes with defects such as double-layered water paper and unwrapped water paper sections.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows:

[0007] Automatic screening and processing device for defective cigarette paper, including

[0008] The vibratory feeder has a feeding channel with two cutting grooves, one in the front and one in the back.

[0009] Each of the cutting slots is equipped with a cutting blade; an optical fiber detector A is provided between two cutting slots, and a screening ring and an optical fiber detector B are provided on one side of the cutting slot located on the rear side.

[0010] When the defective cigarette paper moves upward along the vibrating plate feeding channel and reaches the screening ring, its filter tip cannot pass through the screening ring and gets stuck at the screening ring.

[0011] The cutting blade is connected to a cylinder. When fiber optic detectors A and B determine that a cigarette with a water-paper defect is stuck at the screening ring, the cylinder moves to drive the cutting blade into the cutting groove to cut and remove the cigarette with the water-paper defect.

[0012] As an improvement to the above technical solution, when fiber optic detector A detects that a cigarette has passed by, fiber optic detector B detects that no cigarette has passed by, and the delay exceeds 2 seconds, it is determined that there is a double-layered paper, and the cigarette is stuck at the screening ring because the paper does not wrap the cigarette.

[0013] As an improvement to the above technical solution, the cutting blade is fixed by a blade bracket and installed on both sides of the upper end of the blade bracket, corresponding to the positions of the two upper cutting grooves respectively. The blade bracket is installed on the lower bottom of the vibratory feeder feeding channel, and its bottom is connected to a cylinder.

[0014] As an improvement to the above technical solution, a rejection air nozzle is installed on the back side of the vibratory feeder feeding channel.

[0015] As an improvement to the above technical solution, the optical fiber detector A is installed in the middle of the two cutting grooves, and the optical fiber detector B is fixed at a position 80mm away from the right cutting groove.

[0016] As an improvement to the above technical solution, an L-shaped support frame is installed above the cutting groove located on the far side of the screening ring. This support frame is used to constrain and support the cigarette with the filter tip in front and the cigarette end behind during cutting.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention achieves automatic screening, automatic cutting, and automatic rejection of cigarettes with double-layered paper or unwrapped paper sections by adding a screening device, an optical fiber detection device, a cutting device, and a blow-out rejection device to the vibratory feeder feeding channel.

[0019] This invention further improves the applicability and function of the automatic cigarette sorting and filter cigarette cutting and separation device for removing defective cigarettes, enabling it to achieve complete automation of defective cigarette processing, thereby greatly improving the efficiency of the device in processing residual cigarettes.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1-3 This embodiment is an automatic screening and processing device for defective cigarettes with wet paper, mainly used for the automatic screening and rejection of defective cigarettes with double wet paper or unwrapped wet paper sections. It includes...

[0028] The vibratory feeder has a feeding channel 1, which has two cutting grooves 2, one in front and one in the back.

[0029] Cutting blades 7 are movably installed in the cutting grooves 2. The cutting blades 7 are fixed by the blade brackets 8 and installed on both sides of the upper end of the blade brackets 8, corresponding to the positions of the two cutting grooves 2 above, and can perform longitudinal cutting and reset within them; the blade brackets 8 are installed on the lower side of the bottom of the vibratory feeder channel 1, and the bottom is connected to the cylinder 9 to drive the cutting blades 7.

[0030] An optical fiber detector A4 is installed between the two cutting grooves 2. The cutting groove 2 located on the rear (right) side has a screening ring 3 on one side and an optical fiber detector B5 at an appropriate distance on one side.

[0031] When a cigarette with a defective water paper moves upward along the vibrating feeder feeding channel 1 and reaches the screening ring 3, it cannot pass through the screening ring 3 due to the water paper defect in its filter section, as its circumference is larger than that of a normal cigarette. Therefore, it gets stuck at the screening ring 3. At this time, there are two states for cigarettes 6 with double water paper and unwrapped water paper: one is that the cigarette end is in front and the filter is behind, entering the screening ring 3. Figure 1 One type has the filter tip in front and the cigarette end in the back, failing to enter the screening ring 3. Figure 2 At this point, the position of the cigarette is detected by fiber optic detectors A4 and B5. When it is determined that the cigarette in the channel is a defective cigarette with water-paper defects, the cylinder 9 moves to drive the cutting blade 7 into the cutting groove 2 to cut and remove the defective cigarette.

[0032] In this embodiment, the specific process for determining whether a cigarette in the channel is a defective water-paper cigarette using the fiber optic detection structure is as follows:

[0033] If fiber optic detector A4 detects a cigarette passing by, but fiber optic detector B5 detects no cigarette passing by, and no cigarette is detected within a delay of more than 2 seconds, then it is determined that a cigarette 6 with double-layered wet paper and partially unwrapped wet paper is stuck at the screening ring 3. At this time, fiber optic detector B5 sends a control signal to cylinder 9 to activate it.

[0034] In a preferred embodiment, a rejection nozzle 10 is installed on the back side of the vibratory feeder feeding channel 1. The rejection nozzle 10 faces the cigarettes in the vibratory feeder feeding channel 1 and blows out defective cigarettes after they are cut.

[0035] In a preferred embodiment, fiber optic detector A4 is installed in the middle of the two cutting slots 2, and fiber optic detector B5 is fixed at a position 280mm away from the right cutting slot.

[0036] In a preferred embodiment, an L-shaped support frame is installed above the cutting groove 2 located on the far side of the screening ring 3. This support frame serves to constrain and support the cigarette with the filter tip in front and the cigarette end behind during cutting. The L-shaped support frame is also provided with a cutting groove.

[0037] Specifically, in this embodiment, the screening ring 3, the cutting blade 7, and the blade holder 8 are all made of 45# steel.

[0038] Cylinder 9 uses a Delixi SC32-25 model cylinder to provide power to the cutting blade 7.

[0039] The fiber optic detector is a diffuse reflection fiber optic detector.

[0040] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
