They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-6 As shown, this utility model provides a weighing-type missing pack detection mechanism for cigarette packs, including a support frame 1, a first cigarette pack conveyor belt 2 mounted on the support frame 1, a weighing mechanism mounted on the support frame 1 and corresponding to the output end of the first cigarette pack conveyor belt 2, a second cigarette pack conveyor belt 3 mounted on the support frame 1 and corresponding to the output end of the weighing mechanism, and a rejection mechanism mounted on the support frame 1 and located on one side of the second cigarette pack conveyor belt 3; the weighing mechanism includes components fixed to the support frame 1 and located on the first cigarette pack conveyor belt 2 and the second cigarette pack conveyor belt 3. The weighing fixture 4, the weighing mounting base 5 on the upper end of the weighing fixture 4, the weighing sensor 6 on the weighing mounting base 5, the weighing support plate 7 on the weighing end of the weighing sensor 6, and the weighing bearing plate 8 on the upper end of the weighing support plate 7 are provided. The weighing sensor 6 is fixed on the upper end of the weighing mounting base 5, and the weighing support plate 7 is fixed on the upper end of the weighing end of the weighing sensor 6 and spaced apart from the weighing mounting base 5. The upper end surfaces of the first cigarette conveyor belt 2 and the second cigarette conveyor belt 3 are flush with the upper end surface of the input end of the weighing bearing plate 8.

[0026] Cigarette sticks are conveyed via a first cigarette stick conveyor belt 2 to a second cigarette stick conveyor belt 3 through a weighing mechanism. The cigarette sticks are weighed as they pass through the weighing mechanism to check for missing cigarette packs. The weighing mechanism is installed between the first and second cigarette stick conveyor belts 2 and 3, without requiring modification to the original conveyor belts. The weighing mechanism consists of a weighing fixing frame 4, a weighing mounting base 5, a weighing sensor 6, a weighing support plate 7, and a weighing bearing plate 8. The weighing fixing frame 4 is mounted on a support frame 1, and the weighing mounting base 5 is fixed to the weighing fixing frame 4. The weighing sensor 6 is fixed to the upper end of the weighing mounting base 5, with the weighing end of the weighing sensor 6 facing upwards. The weighing end refers to the sensing end of the weighing sensor 6 that bears the weight of the item being measured. The weighing end of the weighing sensor 6 does not contact the weighing mounting base 5, thus not affecting weighing accuracy. The weighing support plate 7 is horizontally fixed to the weighing end of the weighing sensor 6. The weighing bearing plate 8 is large, facilitating convenient and more stable installation.

[0027] like Figure 2 As shown, the upper surface of the output end of the weighing bearing plate 8 is higher than the upper surface of the first cigarette conveyor belt 2 and the second cigarette conveyor belt 3.

[0028] The input end of the weighing support plate 8 corresponds to and is level with the output end of the first cigarette conveyor belt 2, which facilitates the cigarette sticks to slide onto the weighing support plate 8 by utilizing the inertia of movement during the conveying on the first cigarette conveyor belt 2. In order to extend the sliding time of the cigarette sticks on the weighing support plate 8 and meet the requirements of accurate weighing, the output end of the weighing support plate 8 is tilted upward. The tilt angle is not limited and can be adjusted according to the actual situation. The weighing support plate 8 has a fast conveying speed on the first cigarette conveyor belt 2. When passing through the weighing support plate 8, the upward tilt of the output end of the weighing support plate 8 will reduce the sliding speed towards the second cigarette conveyor belt 3, giving the weighing sensor 6 enough time to weigh the cigarette sticks. This design can effectively improve the accuracy of weighing.

[0029] like Figure 4 As shown, the upper surface of the input end of the weighing bearing plate 8 is provided with an anti-slip structure.

[0030] The anti-slip structure can further slow down the sliding cigarette bar, making the sliding smoother and the weighing more accurate.

[0031] like Figure 4 As shown, the anti-slip structure consists of multiple longitudinally arranged anti-slip grooves 9.

[0032] Multiple anti-slip grooves make processing simpler and effectively reduce the sliding speed of cigarette sticks.

[0033] like Figure 5-6As shown, the weighing mounting base 5 includes a base body 10 and a mounting groove 11 disposed on the upper end of the base body 10. The lower end of the weighing sensor 6 is embedded in the mounting groove 11, and the upper weighing end faces upward.

[0034] After the lower end of the load cell 6 is embedded in the mounting groove 11, it is fixed by bolts. The mounting groove 11 facilitates the installation of the load cell 6.

[0035] like Figure 3 As shown, the weighing mechanism also includes a gantry frame 12 mounted on the support frame 1 and located above the weighing bearing plate 8, and a first photoelectric sensor 13 mounted on the gantry frame 12, with the sensing end of the first photoelectric sensor 13 facing the weighing bearing plate 8.

[0036] The lower ends of both sides of the gantry frame 12 are fixed on the support frame 1. The weighing bearing plate 8 is located in the middle of the gantry frame 12. The first photoelectric sensor 13 is installed on the gantry frame 12. The first photoelectric sensor 13 senses the passage of the smoke bar, thereby controlling the weighing sensor 6 to weigh. The control is simple and convenient.

[0037] like Figure 1-4 As shown, the rejection mechanism includes a rejection frame 14 mounted on the support frame 1 and located on one side of the second tobacco conveyor belt 3, a rejection cylinder 15 mounted on the rejection frame 14, a rejection head 16 mounted on the telescopic end of the rejection cylinder 15, a tobacco receiving box 17 mounted on the other side of the support frame 1, and a second photoelectric sensor 18 mounted on the gantry frame 12 and located above the second tobacco conveyor belt 3. The telescopic end of the rejection cylinder 15 faces the second tobacco conveyor belt 3 and corresponds to the tobacco receiving box 17. The second photoelectric sensor 18 is located above the position of the second tobacco conveyor belt 3 corresponding to the telescopic end of the rejection cylinder 15.

[0038] The gantry frame 12 is connected to an extension bracket in the same direction as the cigarette pack conveyor. The extension bracket extends above the second cigarette pack conveyor belt 3. The second photoelectric sensor 18 is fixed on the extension bracket. The second photoelectric sensor 18 senses the cigarette packs on the second cigarette pack conveyor belt 3 that have moved to the rejection mechanism position. When the defective cigarette pack moves to the rejection mechanism position, the extension end of the rejection cylinder 15 is extended. The rejection head 16 pushes the cigarette pack off the second cigarette pack conveyor belt 3, causing the cigarette pack to slide off the second cigarette pack conveyor belt 3 into the cigarette receiving box 17, thus completing the rejection of the defective cigarette pack. The structure is simple, effective, and easy to control.

[0039] like Figure 1 As shown, it also includes mounting brackets 19 mounted on the support frame 1 and located on both sides of the first cigarette conveyor belt 2, mounting shafts 20 rotatably mounted between the mounting brackets 19, and a pressing wheel 21 mounted on the mounting shaft 20, wherein the pressing wheel 21 is located above the first cigarette conveyor belt 2.

[0040] A pressing wheel 21 is also provided on the first cigarette pack conveyor belt 2. The distance between the pressing wheel 21 and the first cigarette pack conveyor belt 2 is adapted to the height of the cigarette pack after it is laid flat, so as to prevent overlapping cigarette packs from entering the weighing mechanism.
