Description

Technical Field

[0001] The utility model relates to the technical field of cigarette recycling and re-inspection, in particular to an appearance detection mechanism for cigarette recycling and re-inspection. Background Art

[0002] The physical index testing of cigarettes refers to the testing of physical indicators such as cigarette quality, circumference, draw resistance, length, and hardness. In the process of process quality management, further analysis of cigarettes with abnormal indicators is very important, especially abnormal indicators such as draw resistance, weight or ventilation rate of individual cigarettes. It is very necessary to find cigarettes with abnormal indicators and conduct in-depth analysis of the causes of the abnormal indicators.

[0003] For example, a Chinese patent (publication number: CN 219894635 U) discloses a cigarette recovery device, which includes a guide box and a collection box. The guide box is provided with an inlet and an outlet. A guide structure is provided inside the guide box. The guide structure includes a connected arc-shaped channel and a guide cavity. The arc-shaped channel is connected to the inlet to convert the cigarette from longitudinal to transverse to enter the guide cavity. The guide cavity is connected to the outlet. The bottom cavity wall of the guide cavity is tilted downward from the side away from the outlet to the side close to the outlet to guide the cigarette to the outlet. The collection box is connected to the outlet to recover the cigarette. The utility model can switch the tested cigarettes from a vertical state to a horizontal state through the arc-shaped channel and guide them into the guide cavity. Then, the cigarettes are guided into the collection box in an orderly manner through the bottom cavity wall of the guide cavity, so that the cigarettes are arranged in order in the collection box to determine the cigarettes with abnormal tests.

[0004] The above-mentioned cigarette recovery device still has certain shortcomings. The cigarettes that fall vertically from the cigarette outlet of the comprehensive testing equipment can enter the arc channel vertically from the inlet in sequence, and are converted from a vertical state to a horizontal state through the arc channel to enter the guide cavity. Finally, the cigarettes are guided into the collection box in sequence through the bottom cavity wall of the guide cavity. However, it cannot detect the appearance of the cigarettes, resulting in some cigarettes with defects in appearance also entering the collection box, thereby causing defective cigarettes inside the collection box. Therefore, an appearance detection mechanism for cigarette recovery and re-inspection is proposed to solve the above problems. Utility Model Content

A cross bar 6 is fixed between the two vertical rods 5 in the middle, and a fixed block 7 is fixed to the right side of the first fixed plate 1.

[0024] See also Figure 1-3 In order to facilitate the inspection of the appearance of cigarettes, the detection mechanism 3 in this embodiment includes a box body 301 fixed to the front side of the front vertical rod 5, and a first motor 302 is fixed to the right side of the box body 301. The output shaft of the first motor 302 is fixed to the first threaded rod 303, and the outer surface of the first threaded rod 303 is threadedly connected to the moving block 304. When the first motor 302 is working, it drives the first threaded rod 303 to rotate, and drives the moving block 304 to move. A rod sleeve 305 is fixed to the back side of the moving block 304, and the output end of the cylinder 306 is slidably connected to the inside of the rod sleeve 305. The cylinder 306 is fixed to the upper surface of the rod sleeve 305.

[0025] A connecting plate 307 is fixed to the output end of the cylinder 306, and a base plate 308 is fixed to the lower surface of the connecting plate 307. The cylinder 306 works to drive the connecting plate 307 and the base plate 308 to move together. The detection mechanism 3 also includes a first detection head 309 fixed to the upper surface of the fixed block 7 and a second detection head 310 fixed to the lower surface of the cross bar 6. The appearance of the lower surface of the cigarette is detected by the first detection head 309, and the appearance of the upper surface of the cigarette is detected by the second detection head 310.

[0026] Among them, the left side of the first threaded rod 303 is rotatably connected to the left side of the inner cavity of the box body 301 through the bearing seat, which increases the stability of the first threaded rod 303 during rotation. The moving block 304 is I-shaped, and a sliding hole is opened on the back of the box body 301. The moving block 304 is slidably connected to the inside of the sliding hole, which facilitates the movement of the moving block 304 and increases the stability of the moving block 304 during movement.

[0027] In addition, two limit blocks are fixed on the back of the moving block 304, and two limit rods are fixed on the upper surface of the connecting plate 307. The limit rods are slidably connected to the inside of the limit blocks to increase the stability of the bottom plate 308 when moving.

[0028] It should be noted that the appearance of the lower surface of the cigarette is inspected by the first detection head 309, and the appearance of the upper surface of the cigarette is inspected by the second detection head 310. The first detection head 309 and the second detection head 310 are both devices for detecting the appearance of cigarettes in the prior art, and their working principles are no longer described in detail in this article. The electrical components appearing in the article are all electrically connected to the main controller and the power supply, and the electrical components appearing in the article are all conventional known devices, and this application will not go into too much detail. The main controller can be a conventional known device that controls a computer, etc. The control circuit of the main controller can be realized by simple programming by technicians in this field, and the provision of power is also common knowledge in this field. In addition, the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and circuit connection in detail.

[0029] The detection mechanism 3 in this embodiment performs an appearance inspection on the upper surface of the cigarette on the turntable 2 through the second detection head 310. When the cigarette is fixed by the clamping mechanism 4, the cylinder 306 moves the connecting plate 307, the bottom plate 308 and the cigarette upward a certain distance. The first motor 302 drives the first threaded rod 303 to rotate, driving the moving block 304, the rod sleeve 305, the connecting plate 307 and the bottom plate 308 to move together, so that the cigarette moves to the top of the first detection head 309, and the appearance inspection of the bottom of the cigarette is performed by the first detection head 309.

[0030] See also Figure 4 In order to fix the cigarettes, the clamping mechanism 4 in this embodiment includes multiple shells 401 fixed to the lower surface of the bottom plate 308, and a third motor 402 is fixed to the upper surface of the inner cavity of the shell 401. The output shaft of the third motor 402 is fixed to the first bevel gear 403. The front and rear sides of the inner cavity of the shell 401 are rotatably connected with a second threaded rod 404 through a bearing seat. The outer surface of the second threaded rod 404 is fixed with a second bevel gear 405. The first bevel gear 403 is meshed with the second bevel gear 405. The third motor 402 drives the first bevel gear 403 to rotate, and drives the second bevel gear 405 and the second threaded rod 404 to rotate together.

[0031] The outer surface of the second threaded rod 404 is threadedly connected to two movable blocks 406. The thread of the second threaded rod 404 is divided into two sections, and the two sections of thread are in opposite directions. By rotating the second threaded rod 404, the two movable blocks 406 are driven to move relative to each other or opposite to each other at the same time. The opposite sides of the two movable blocks 406 are fixed with connecting rods 407 that penetrate and extend to the outside of the shell 401. The connecting rods 407 are U-shaped, and the opposite sides of the two connecting rods 407 are fixed with clamps 408 for clamping and fixing cigarettes.

[0032] Among them, two vertical blocks are fixed on the upper surface of the inner cavity of the shell 401, and sliding rods are fixed on the opposite sides of the two vertical blocks. The movable block 406 is slidably connected to the outer surface of the sliding rod to increase the stability of the movable block 406 when moving. The lower surface of the shell 401 is provided with multiple grooves adapted to cigarettes, which is convenient for equidistant clamping of cigarettes.

[0033] In the clamping mechanism 4 of this embodiment, the third motor 402 drives the first bevel gear 403 to rotate, and drives the second bevel gear 405 and the second threaded rod 404 to rotate together, so that the two movable blocks 406 move relative to each other at the same time. The movable block 406 drives the clamping plate 408 to move through the connecting rod 407 to clamp and fix the cigarette.

[0034] The working principle of the above embodiment is:

[0035] (1) When the cigarette rotates on the turntable 2, the second detection head 310 performs an appearance inspection on the upper surface of the cigarette. When the cigarette is fixed by the clamping mechanism 4, the output end of the cylinder 306 contracts, driving the connecting plate 307, the bottom plate 308 and the cigarette to move upward. When the connecting plate 307 moves, it will drive the limit rod to slide inside the limit block, increasing the stability of the cigarette when moving. When the cigarette moves to a certain height, the first motor 302 starts, driving the first threaded rod 303 to rotate. When the first threaded rod 303 rotates, it will drive the moving block 304 to move, and through the moving block 304, it drives the rod sleeve 305, the connecting plate 307 and the bottom plate 308 to move together, so that the cigarette moves to the top of the first detection head 309, and the first detection head 309 performs an appearance inspection on the bottom of the cigarette.

[0036] (2) When the cigarette is located between the two clamping plates 408, the third motor 402 is started, and the third motor 402 drives the first bevel gear 403 to rotate, and the first bevel gear 403 drives the second bevel gear 405 and the second threaded rod 404 to rotate together. Since the two sections of the thread of the second threaded rod 404 are in opposite directions, when the second threaded rod 404 rotates, it will drive the two movable blocks 406 to move relative to each other at the same time. The movable block 406 will slide on the outer surface of the sliding rod, increasing the stability of the movable block 406 when it moves. When the movable block 406 moves, it will drive the clamping plate 408 to move through the connecting rod 407 to clamp the cigarette.
