Description

Technical Field

[0001] The invention belongs to the technical field of cigarette detection, and in particular relates to a cigarette smoldering detection box. Background Art

[0002] During cigarette production, cigarettes need to be frequently inspected (such as cigarette end-fall detection, cigarette extinction detection, and cigarette burning rate detection). Among them, cigarette extinction is a mandatory inspection item and is classified as a Class A quality defect. This is stipulated in the national cigarette standard GB5606.4-2005, and its technical indicators require that the cigarette should not be extinguished after being ignited, that is, after the cigarette is ignited, the length of the cigarette continuously smoldering should not be less than 40mm. For a long time, the technical tools used by cigarette companies for cigarette extinction detection are steel rulers and smoldering racks. The detection process is mainly based on manual measurement. The error of manual detection is relatively large, and it is difficult to ensure the measurement consistency and accuracy of the detection. In addition, manual statistics increase the workload of the detection personnel, and the detection efficiency is low. Summary of the Invention

[0003] The purpose of the present invention is to provide a cigarette smoldering detection box, which is simple to operate and ensures measurement consistency and accuracy during detection.

[0004] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0005] A cigarette smoldering detection box comprises a box body, a smoldering rack arranged in the box body and an electric heating plate, the smoldering rack comprises a bottom plate, a bracket fixed on the bottom plate, a cigarette upper cover, and a cigarette lower cover, the cigarette lower cover is fixed on the bracket, the cigarette upper cover is rotatably connected to the cigarette lower cover, the cigarette upper cover and the cigarette lower cover are both provided with mutually matching semi-cylindrical grooves, when the cigarette upper cover and the cigarette lower cover are closed, the semi-cylindrical grooves of the cigarette upper cover and the cigarette lower cover form a circular hole, the cigarette lower cover is provided with a The air intake hole is used for inhalation when the cigarette is ignited, one end of the air intake hole is connected to the semi-cylindrical groove on the lower cover of the cigarette, and the other end of the air intake hole is connected to the air pump through an air pipe. An air pipe joint is installed at the connection between the air intake hole and the air pipe. A first slide rail and a second slide rail are fixedly provided on the bracket, and the first slide rail and the second slide rail are located at both ends of the lower cover of the cigarette, and sliding grooves are provided on the first slide rail and the second slide rail, and a movable plate is connected between the first slide rail and the second slide rail. The movable plate is provided with a sliding column slidably connected in the sliding groove, and the sliding column is integrally formed with the movable plate, and a semi-cylindrical notch is opened on the movable plate to match the semi-cylindrical groove of the lower cover of the cigarette, and the center points of the cross sections of the semi-cylindrical groove on the lower cover of the cigarette and the semi-cylindrical notch on the movable plate are located on the same horizontal line, and scales are provided on the first slide rail and the second slide rail, and the smoldering rack is provided with a recycling box and an inclined closing groove, and the recycling box is located directly below the outlet of the inclined closing groove, and the recycling box is fixed on the bottom plate, and the inclined closing groove is fixed on the bracket, and the cigarettes dropped from the smoldering rack can automatically fall into the recycling box; a telescopic rod is also provided in the box body, and the electric heating plate is fixedly connected to the telescopic rod, and one end of the telescopic rod away from the electric heating plate is fixed to the box body, and a controller is provided on the front side wall of the box body, and the controller includes a heating switch and a suction switch, the heating switch is electrically connected to the electric heating plate, and the suction switch is electrically connected to the suction pump.

[0006] Furthermore, a hinge is provided between the upper cigarette cover and the lower cigarette cover, so that the upper cigarette cover and the lower cigarette cover are rotatably connected.

[0007] Furthermore, the semi-cylindrical grooves on the upper cover and the lower cover of the cigarette form a circular hole, and the diameter of the circular hole is equal to the diameter of the cigarette. This design allows the filter end of the cigarette to form a closed space in the circular hole when the cigarette is inhaled, so that the cigarette can be inhaled through the suction hole.

[0008] Furthermore, the diameter of the air intake hole is smaller than the diameter of the cigarette, so that a height difference is formed between the semi-cylindrical groove of the lower cover of the cigarette and the contact surface of the air intake hole, so that when the cigarette is placed, the filter end face of the cigarette can be aligned with the air intake hole by relying on this height difference.

[0009] Furthermore, a fastener is provided at the end of the sliding column. When the position of the movable plate is determined, the sliding column is fixed in the sliding groove by the fastener, that is, the movable plate is fixed on the first slide rail and the second slide rail to prevent the movement of the movable plate during the test from affecting the detection of smoldering cigarettes.

[0010] Furthermore, the zero scale of the ruler is the contact surface position between the semi-cylindrical groove of the lower cover of the cigarette and the suction hole, that is, the end face placement position of the cigarette filter, and the scale on the ruler is marked from the end face placement position of the cigarette filter to the direction of the electric heating plate.

[0011] Furthermore, air holes are provided on the left side wall, rear side wall and right side wall of the box body, and a smoke exhaust hole is provided on the top of the box body. During the burning process of cigarettes, the smoke generated is discharged from the smoke exhaust hole. At the same time, the burning box body of cigarettes consumes a large amount of oxygen, and air circulation is required through the air holes to reduce the interference of insufficient oxygen on the smoldering detection results.

[0012] Furthermore, an infrared electronic induction counter is provided directly below the outlet of the inclined closing groove, and the infrared electronic induction counter is fixed on the recycling box. When cigarettes enter the recycling box along the inclined closing groove, the infrared electronic induction counter can sense the fallen cigarettes and count the number of fallen cigarettes.

[0013] In summary, the beneficial effects of the present invention are:

[0014] 1. Compared with existing cigarette detection devices, the present invention uses a smoldering rack to detect whether the smoldering length of a cigarette is qualified. When a cigarette burns to the movable plate, it will continue to burn. As the burning end of the cigarette continues to burn, it gradually loses support on the movable plate, causing the cigarette to fall due to unbalanced force. The cigarette is then judged to be smoldering qualified. If the cigarette extinguishes before burning to the movable plate, that is, the smoldering length of the cigarette is less than the standard value, the cigarette is smoldering unqualified. The smoldering detection box of this cigarette has a simple structure and can solve the problem of large measurement errors caused by manual detection in existing cigarette smoldering detection devices, thereby improving measurement accuracy.

[0015] 2. For testing cigarettes of the same length, the position of the movable plate only needs to be calibrated once before the test. No further measurement or calibration is required during the test, effectively ensuring measurement consistency during testing.

[0016] 3. The electric heating plate installed in the box is combined with the suction pipe. When the electric heating plate is used to light a cigarette, the cigarette can be ignited inside the box, which is faster and more convenient.

[0017] 4. There are ventilation holes on the side walls of the box and smoke exhaust holes on the top of the box. During the burning process of cigarettes, the smoke generated is discharged from the smoke exhaust holes. At the same time, the burning box consumes a lot of oxygen, so air circulation is required through the ventilation holes to reduce the interference of insufficient oxygen on the smoldering detection results.

[0018] 5. The bracket of the smoldering rack is equipped with an inclined closing groove. The cigarettes dropped from the cigarette mounting seat can automatically fall into the recycling box, realizing the automatic recycling of qualified cigarettes. At the same time, the infrared electronic induction counter is used to count the number of fallen cigarettes, which can avoid errors in personnel statistics, reduce the workload of detection personnel, and improve detection efficiency.

[0027] The method of use of the present invention is as follows:

[0028] According to the length of the detected cigarette, in this embodiment, the length of the cigarette is 84 mm. The sliding column 17 is moved along the sliding groove 15 on the first slide rail 13 and the second slide rail 14 to the movable plate 16 and adjusted to a position where the scale on the scale 20 shows 44 mm, ensuring that the length of the burning end of the cigarette extending out of the movable plate 16 is 40 mm, which is equal to the standard smoldering length. After the position is determined, the sliding column 17 is fixed in the sliding groove 15 by the fastener 18, that is, the movable plate 16 is fixed to the first slide rail 13 and the second slide rail 14. After the movable plate 16 is fixed, the cigarette 28 to be tested is placed on the smoldering rack 2, one end of the filter tip of the cigarette 28 is placed in the semi-cylindrical groove 8 on the cigarette lower cover 6 and the end face of the filter tip is aligned with the end face of the suction hole close to one end of the cigarette, the middle part of the cigarette 28 is placed on the semi-cylindrical notch 19 of the movable plate 16, and the cigarette upper cover 5 is closed after the cigarette 28 is placed.
