Description

Technical Field

[0001] The invention relates to the technical field of cigarette extinction detection, in particular to a smoldering rack and an extinction detection method using the smoldering rack. Background Art

[0002] The phenomenon of slow burning in the absence of flame is called smoldering. In the tobacco industry, the smoldering length is one of the important indicators for judging the quality of cigarettes, and the smoldering length of cigarettes can be measured through flameout inspection.

[0003] At present, the flameout test of cigarettes is carried out by a stepped smoldering rack, which can test the flameout of dozens of cigarettes at a time. However, the stepped smoldering rack is large in size and bulky in structure, which may cause damage during transportation. At the same time, the smoldering rack is provided with receiving grooves at intervals. The filter end of the cigarette is inserted into the receiving groove while the main body of the cigarette is kept suspended in the air to fix the cigarette. As a result, the cigarettes need to be lit one by one during the lighting operation, which is not only time-consuming and labor-intensive, but also poses a risk of burns. In addition, since this inspection method requires that the smoldering length be judged to be qualified after all the cigarettes have been burned out, the smoldering time of the cigarettes is long and the amount of smoke leakage is large, which may easily exceed the tolerance of the indoor smoke alarm and trigger the alarm, and is not conducive to the safety and health of the inspectors. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a smoldering rack which has a light structure and can perform flameout inspection safely and efficiently.

[0005] The present invention adopts the following technical solution:

[0006] The present invention provides a smoldering rack, comprising a left bracket, a right bracket, a rear baffle and a corrugated plate;

[0007] The left bracket and the right bracket are respectively connected vertically to the two ends of the corrugated plate in the width direction, and anti-scalding handles are fixed at the middle positions of the outer sides of the left bracket and the right bracket;

[0008] The rear baffle is vertically connected to one end of the corrugated plate in the length direction;

[0009] The corrugated plate has ten V-shaped notches extending continuously along the width direction, each V-shaped notch can abut against the outer periphery of a cigarette, and the free end of the corrugated plate is the flameout qualified line of the cigarette.

[0010] Preferably, it also includes a cover plate, which is fixed on the corrugated plate and vertically connected to the rear baffle. The cover plate covers a portion of one end of the corrugated plate in the length direction and forms ten accommodating grooves together with ten V-shaped recesses, each of which can abut against a portion of the outer periphery of a cigarette filter.

[0011] Preferably, the left bracket, the right bracket, the rear baffle, the corrugated plate, the cover plate and the anti-scalding handle are all made of 304 stainless steel.

[0012] The present invention also provides a flameout inspection method, which uses the above-mentioned smoldering rack and includes the following steps:

[0013] S1: Move the smoldering rack to the detection position and place ten or less cigarettes one by one in the continuous V-shaped notches of the corrugated plate;

[0014] S2: Axially adjust the cigarettes placed on the corrugated plate so that the filter tip of each cigarette is axially abutted in a corresponding receiving groove, and the ignition ends of all cigarettes are suspended and flush;

[0015] S3: heating and igniting all cigarettes at the same time, and placing the smoldering rack in a transparent smoke isolation cover;

[0016] S4: Manually observe the real-time smoldering situation of the cigarettes in the smoke isolation hood, and promptly remove the cigarettes that are smoldering on the corrugated plate, or remove the cigarettes that are naturally extinguished before smoldering to the corrugated plate.

[0017] Preferably, in step S3, all cigarettes are heated and ignited simultaneously by the horizontally placed electric heating wires.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The smoldering rack of the present invention comprises a left bracket, a right bracket, a rear baffle, a corrugated plate and an anti-scalding handle. The entire structural design is lighter and easier to carry than the existing stepped smoldering rack. The anti-scalding handle can facilitate the operator to adjust and move the setting position of the smoldering rack, effectively avoid burns, and ensure the safety of the operator.

[0020] When the smoldering rack of the present invention is in use, ten or less cigarettes are arranged in ten V-shaped notches of the corrugated plate in a one-to-one correspondence, and the filter tip of each cigarette is in contact with the rear baffle, so that the ignition ends of all cigarettes can be aligned, so that all cigarettes can be ignited at one time by the ignition device, which greatly shortens the time consumption of the ignition stage in the flameout inspection and avoids the risk of burns caused by manual ignition;

[0021] The free end of the corrugated plate can be used to check whether the smoldering length of the cigarette is qualified. When the cigarette smolders onto the corrugated plate, it means that the smoldering length of the cigarette is qualified. At this time, the cigarette can be removed through manual intervention and other means. Since the continued smoldering of qualified cigarettes is avoided, the smoke leakage concentration is reduced to a certain extent, the alarm of the indoor smoke alarm is avoided, the comfort of the inspectors is improved, which is beneficial to the safety and health of the inspectors and also improves the inspection efficiency.

[0022] Therefore, the smoldering rack of the present invention can perform flameout inspections safely and efficiently; using the smoldering rack of the present invention to perform flameout inspections has high inspection efficiency and can improve the comfort of inspectors, which is beneficial to the safety and health of inspectors.

[0032] The rear baffle 3 is vertically connected to one end of the corrugated plate 4 in the length direction;

[0033] The corrugated plate 4 has ten V-shaped notches extending continuously along the width direction, each V-shaped notch can abut against the outer periphery of a cigarette, and the free end of the corrugated plate 4 is the flameout qualified line of the cigarette.

[0034] See also Figure 2 The smoldering rack of this embodiment includes a left bracket 1, a right bracket 2, a rear baffle 3, a corrugated plate 4 and an anti-scalding handle 6. The entire structural design is lighter and easier to carry than the original stepped smoldering rack. The setting of the anti-scalding handle 6 can facilitate the operator to adjust and move the setting position of the smoldering rack, effectively avoid burns, and ensure the safety of the operator.

[0035] When the smoldering rack of this embodiment is in use, ten or less cigarettes are arranged one by one in the ten V-shaped notches of the corrugated plate 4, and the filter of each cigarette is in contact with the rear baffle 3, so that the ignition ends of all cigarettes can be aligned, so that all cigarettes can be ignited at one time by the ignition device, which greatly shortens the time consumption of the cigarette lighting stage in the flameout test and avoids the risk of burns caused by manual ignition; and the free end of the corrugated plate 4 can test whether the smoldering length of the cigarette is qualified. When the cigarette smolders to the corrugated plate 4, it means that the smoldering length of the cigarette is qualified. At this time, the cigarette can be removed by means of manual intervention, etc., because the qualified cigarettes are avoided from continuing to smolder, the smoke leakage concentration is reduced to a certain extent, the indoor smoke alarm is avoided, the comfort of the inspectors is improved, which is beneficial to the safety and health of the inspectors and also improves the inspection efficiency. Therefore, the smoldering rack of this embodiment can safely and efficiently perform flameout inspections.

[0036] Embodiment 2

[0037] See also Figure 3 On the basis of the first embodiment, the smoldering rack of this embodiment further includes a cover plate 5, which is fixed on the corrugated plate 4 and vertically connected to the rear baffle 3. The cover plate 5 covers a portion of one end of the corrugated plate 4 in the length direction and forms ten accommodating grooves together with ten V-shaped recesses, each of which can abut against a portion of the outer periphery of a cigarette filter.

[0038] The arrangement of the cover plate 5 can ensure that the cigarettes are not easily shaken or dropped when lighting a cigarette, thereby ensuring the success rate of igniting all the cigarettes at one time.

[0039] It should be noted that the setting position of the flameout qualified line of a cigarette is determined according to the provisions of the national standard for smoldering cigarettes. Different settings of the flameout qualified line are specified for cigarettes of different specifications. Therefore, each cigarette of different specifications corresponds to a corrugated plate 4 of a certain size, and the length of the accommodating groove must also ensure that the filter of the cigarette can be partially accommodated therein.

[0040] For example, in a cigarette with a filter, the length of the hanging part of the cigarette should be guaranteed to be about 40mm:

[0041] a. For the 75mm length of the cigarette to be tested, the length of the corrugated plate 4 is taken as 34mm, and the length of the accommodating groove is taken as 8mm;

[0042] b. For the 84mm length of the cigarette to be tested, the length of the corrugated plate 4 is 43mm, and the length of the accommodating groove is 12mm;

[0043] c. For the 89mm length of the cigarette to be tested, the length of the corrugated plate 4 is 48mm, and the length of the accommodating groove is 16mm;

[0044] d. For a 97mm length cigarette to be tested, the length of the corrugated plate 4 is 56mm, and the length of the accommodating groove is 22mm.

[0045] Embodiment 3

[0046] On the basis of the second embodiment, the left bracket 1, the right bracket 2, the rear baffle 3, the corrugated plate 4, the cover plate 5 and the anti-scalding handle are all made of 304 stainless steel.

[0047] 304 stainless steel has high strength, is non-flammable, and is safer and more reliable. The left bracket 1, the right bracket 2, the rear baffle 3, the corrugated plate 4, the cover plate 5 and the anti-scalding handle are all made of 304 stainless steel, which is beneficial to prolonging the service life of the smoldering rack; at the same time, the corrugated plate 4 made of 304 stainless steel is more eye-catching. When observing the smoldering of the cigarette, the visibility of the corrugated plate 4 on the smoldering rack can also be observed to assist in judging whether the cigarette is smoldering on the corrugated plate 4.

[0048] also:

[0049] The present invention also provides an embodiment of a flameout inspection method, which uses the smoldering rack of the above-mentioned embodiment 3 and includes the following steps:

[0050] S1: Move the smoldering rack to the detection position and place ten or less cigarettes one by one in the continuous V-shaped notches of the corrugated plate 4;

[0051] S2: Axially adjust the cigarettes arranged on the corrugated plate 4 so that the filter tip of each cigarette is axially abutted in a corresponding receiving groove, and the ignition ends of all cigarettes are suspended and flush;

[0052] S3: heating and igniting all cigarettes at the same time, and placing the smoldering rack in a transparent smoke isolation cover;

[0053] S4: manually observing the real-time smoldering condition of the cigarettes in the smoke isolation cover, and promptly removing the cigarettes that are smoldering on the corrugated plate 4 , or removing the cigarettes that are naturally extinguished before smoldering on the corrugated plate 4 .

[0054] The flameout inspection method of the present embodiment can ignite multiple cigarettes at one time, which greatly shortens the time spent in the lighting stage of the flameout inspection and avoids the risk of burns caused by manual ignition; the free end of the corrugated plate 4 can inspect whether the smoldering length of the cigarette is qualified. When the cigarette smolders onto the corrugated plate 4, it means that the smoldering length of the cigarette is qualified. At this time, the cigarette smoldering onto the corrugated plate 4 can be removed and processed. Since the continued smoldering of qualified cigarettes is avoided, the smoke leakage concentration is reduced to a certain extent, thereby improving the inspection efficiency; at the same time, the setting of the transparent smoke isolation cover can effectively reduce the smoke leakage concentration, avoid the alarm of the indoor smoke alarm, and improve the comfort of the inspector.

[0055] Furthermore, in order to ensure that the success rate of one-time ignition is 100%, in step S3 of the flameout inspection method, all cigarettes are heated and ignited simultaneously by the horizontally placed electric heating wire.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
