[0002] During cigarette production, cigarettes need to be conveyed, for example, from the cigarette rolling machine to the packaging machine. During this conveying process, cigarettes often need to be buffered by buffering equipment. Inevitably, some cigarettes may become skewed during conveying and during the buffering process; these skewed cigarettes are called "misplaced cigarettes." Misplaced cigarettes can cause quality defects such as wrinkles, tears, and breaks. These defective cigarettes may be mixed into the finished cigarettes, causing quality defects. Furthermore, the downtime and handling of misplaced cigarettes increase the workload of operators and reduce equipment operating efficiency.

[0025] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] like Figures 1-3As shown, the self-resetting device for detecting disordered smoke provided in this embodiment includes: an L-shaped bracket 1, the L-shaped bracket 1 including a horizontal part and a vertical part, a smoke baffle door displacement detection sensor 7 is provided on the horizontal part, a detachably connected buffer pad 4 is provided on one side of the vertical part, and the buffer pad 4 can slide along the vertical part, the buffer pad 4 is installed on the smoke baffle door 6.

[0028] The smoke baffle 6 is a structure on the smoke storage compartment of the packaging equipment, and it is made of glass. L-shaped brackets 1 are installed on both sides of the smoke storage compartment at a distance of 110mm-130mm from the bottom edge. The opening and closing state of the smoke baffle 6 can be detected by the smoke baffle displacement detection sensor 7. In this invention, the smoke baffle displacement detection sensor 7 is a metal sensor. Specifically, the smoke baffle displacement detection sensor 7 can detect whether the position of the metal bracket at the bottom of the smoke baffle 6 has changed, thereby determining whether the smoke baffle 6 is open. Thus, the smoke baffle displacement detection sensor 7 can be mechanically linked with the smoke baffle 6.

[0029] Furthermore, the smoke-blocking door displacement detection sensor 7 is connected to an intelligent (ARM) controller, and the smoke-blocking door displacement detection sensor 7 and the intelligent controller are bidirectionally electrically connected. Specifically, the smoke-blocking door displacement detection sensor 7 sends the detected displacement signal of the smoke-blocking door 6 to the intelligent (ARM) controller. Then, through the cooperation of the intelligent controller, the industrial control computer, and the alarm, the alarm is triggered. After the alarm is triggered, the intelligent controller sends a reset command to the smoke-blocking door displacement detection sensor 7, causing the smoke-blocking door displacement detection sensor 7 to reset in response to the reset command, thereby resetting the smoke-blocking door 6. This achieves self-resetting of the smoke-blocking door detection. In some embodiments of this utility model, the smoke-blocking door displacement detection sensor 7 is an Omron E3Z-T61. It should be noted that this utility model does not specifically limit the type and model of the smoke-blocking door displacement detection sensor 7. In one embodiment of this utility model, the triggering condition of the smoke-blocking door displacement detection sensor 7 is: the opening angle of the smoke-blocking door 6 is ≥30°. It should be noted that this utility model does not specifically limit the triggering condition of the smoke-blocking door displacement detection sensor 7.

[0030] Furthermore, the thickness of the buffer pad 4 is 8mm-12mm, for example, 10mm. It should be noted that this utility model does not specifically limit the thickness and material of the buffer pad 4. The buffer pad 4 enables the connection between the vertical part and the smoke baffle 6, thereby fixing the L-shaped bracket 1 to the main body of the packaging equipment. At the same time, the buffer pad 4 increases the distance between the horizontal part and the main body of the equipment. The buffer pad 4 can slide between itself and the vertical part, facilitating the determination of the appropriate trigger position for the smoke baffle displacement detection sensor 7.

[0031] Furthermore, the vertical portion has a bent structure. The horizontal portion and the buffer pad 4 are located on the same side of the vertical portion, and the horizontal portion is located above the vertical portion.

[0032] Furthermore, a vertical mounting hole 3 is provided on the horizontal part, and the smoke-blocking door displacement detection sensor 7 is installed in the vertical mounting hole 3. The diameter of the vertical mounting hole 3 is 11mm-13mm, for example, 12mm. It should be noted that this utility model does not specifically limit the installation position and diameter of the vertical mounting hole 3 on the horizontal part.

[0033] Furthermore, the vertical section is provided with several horizontal adjustment holes 2, and the buffer pad 4 is provided with several double positioning pin holes 5. The number of horizontal adjustment holes 2 and double positioning pin holes 5 is the same, and their positions correspond. The horizontal adjustment holes 2 and double positioning pin holes 5 allow for connection between the vertical section and the buffer pad 4, facilitating their relative sliding and making it easier to determine the appropriate trigger position for the smoke-blocking door displacement detection sensor 7.

[0034] Specifically, each of the horizontal adjustment holes 2 is an elongated hole with semicircles at both ends. The diameter of the two semicircles of each horizontal adjustment hole 2 is 4.5mm-5.5mm, for example, 5mm, and the center distance between the two semicircles is 9.5mm-10.5mm, for example, 10mm. The diameter of the double positioning pin hole 5 is 3.5mm-4.5mm, for example, 4mm. It should be noted that this utility model does not specifically limit the position, shape, and diameter of the horizontal adjustment hole 2 and the double positioning pin hole 5.

[0035] During operation, the smoke baffle door displacement detection sensor 7 can detect the opening and closing status of the smoke baffle door 6. The sensor 7 is mechanically linked to the smoke baffle door 6, and the opening of the smoke baffle door 6 can be used as a trigger signal for alarm reset. Each system reset does not require the operator to go to the back of the equipment to reset via the intelligent controller panel; that is, no deliberate reset is needed. Simply opening the rear smoke baffle door 6 while normally handling defective cigarettes and simultaneously triggering the smoke baffle door displacement detection sensor 7 will trigger the alarm reset, achieving self-reset of the disorderly smoke detection.

[0036] The self-resetting device for detecting disordered smoke provided in this embodiment of the invention can achieve mechanical linkage with the smoke-blocking door through a smoke-blocking door displacement detection sensor. The opening operation of the smoke-blocking door is used as the trigger signal for alarm reset. When the rear smoke-blocking door is opened, the smoke-blocking door displacement detection sensor is triggered, and the alarm reset is performed, thus realizing the self-resetting of disordered smoke detection. It is especially suitable for quality inspection and equipment interlocking control of medium and high speed packaging machines such as GD type and ZB47 type.

[0037] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
