The first driving assembly 210 pushes the sanitary napkin packages on the output end of the first conveyor belt 100 onto the electronic weighing platform 220. The second driving assembly 230 is fixedly arranged above the electronic weighing platform 220. The second driving assembly 230 pushes the sanitary napkin packages on the electronic weighing platform 220 to the input end of the second conveyor belt 300;

[0026] A jet pump 310 is fixedly arranged on the side of the second conveyor belt 300, and the jet pump 310 blows out the sanitary napkin packages on the second conveyor belt 300 laterally.

[0027] During use, the staff starts the assembly line device, and the sanitary napkin packages move on the first conveyor belt 100. When the sanitary napkin packages reach the output end of the first conveyor belt 100, the first driving component 210 starts and pushes the sanitary napkin packages onto the electronic weighing platform 220. The electronic weighing platform 220 measures the weight of the sanitary napkin packages, and then the second driving component 230 pushes the sanitary napkin packages to the input end of the second conveyor belt 300. The second conveyor belt 300 drives the sanitary napkin packages to move. When the sanitary napkin packages reach the sensing area of the jet pump 310, if the weight of the sanitary napkin packages reaches the standard, they will smoothly pass through the sensing area and continue to move forward. If the weight of the sanitary napkin packages does not reach the standard, the jet pump 310 starts, and the nozzles of the jet pump 310 jet air to blow out the sanitary napkin packages along the side of the second conveyor belt 300, achieving the purpose of removing unqualified products.

[0028] Preferably, the first driving component 210 includes a first cylinder 211 and a first pushing plate 212. The first cylinder 211 is fixedly arranged behind the output end of the first conveyor belt 100, and the output rod of the first cylinder 211 is fixedly connected to the first pushing plate 212. The first cylinder 211 is used to drive the first pushing plate 212 to move onto the electronic weighing platform 220.

[0029] Preferably, a second baffle 213 is fixedly connected to the side of the first pushing plate 212 close to the output end of the first conveyor belt 100. When the first pushing plate 212 pushes a portion of sanitary napkin packages onto the electronic weighing platform 220, the second baffle 213 can block other sanitary napkin packages on the first conveyor belt 100 from contacting the output end of the first driving component 210, avoiding other sanitary napkin packages from affecting the reset of the first pushing plate 212.

[0030] Preferably, the second driving component 230 includes a second cylinder 231, a third cylinder 232, and a second pushing plate 233. The second cylinder 231 is fixedly arranged above the electronic weighing platform 220, and the output rod of the second cylinder 231 is fixedly connected to the third cylinder 232. The third cylinder 232 is arranged outside the electronic weighing platform 220. The second cylinder 231 is used to drive the third cylinder 232 to move horizontally above the input end of the second conveyor belt 300. The output rod of the third cylinder 232 is fixedly connected to the second pushing plate 233. The third cylinder 232 is used to drive the second pushing plate 233 to move downward to abut against the electronic weighing platform 220.

[0031] Preferably, a fourth cylinder 221 is fixedly arranged above the electronic weighing platform 220. A third push plate 222 is fixedly arranged on the output rod of the fourth cylinder 221. The third push plate 222 is arranged outside the electronic weighing platform 220, and its bottom abuts against the non-weighing area of the electronic weighing platform 220. The third push plate 222 is opposite to the first driving assembly 210 in position. The fourth cylinder 221 is used to drive the third push plate 222 to move to the center of the electronic weighing platform 220. On the one hand, the third push plate 222 plays a blocking role, which can prevent the sanitary napkin package pushed by the first driving assembly 210 from being overly displaced outside the electronic weighing platform 220. On the other hand, the third push plate 222 plays a resetting role, which can push the overly displaced sanitary napkin package to the center of the electronic weighing platform 220, facilitating the second driving assembly 230 to push the sanitary napkin package on the electronic weighing platform 220 to the input end of the second conveyor belt 300.

[0032] Preferably, a storage table 320 is fixedly arranged on the side of the second conveyor belt 300. The storage table 320 is opposite to the nozzle of the air jet pump 310 in position. The air jet pump 310 blows the unqualified sanitary napkin packages into the storage table 320, facilitating the collection of unqualified sanitary napkin packages.

[0033] Preferably, a counter 330 is fixedly arranged on the side of the second conveyor belt 300. The position of the counter 330 is farther from the input end of the second conveyor belt 300 compared to the position of the nozzle of the air jet pump 310. The counter 330 can record the number of qualified sanitary napkin packages after the assembly line starts, facilitating the staff to count.

[0034] Preferably, a guiding wall 110 is arranged on the first conveyor belt 100. The guiding wall 110 is arranged at the output end of the first conveyor belt 100 and is used to limit the width of the output end, ensuring that only a single sanitary napkin package can pass through the output end smoothly at the same time. One side of the guiding wall 110 is fixedly connected with a support rod 120. The support rod 120 is fixedly arranged on the side of the first conveyor belt 100. The support rod 120 is used to determine the position of the guiding wall 110 on the first conveyor belt 100. By arranging the guiding wall 110, the width of the output port of the first conveyor belt 100 can be reduced, avoiding the situation that the first driving assembly 210 pushes multiple sanitary napkin packages onto the electronic weighing platform 220 at one time.

[0035] Preferably, an adjusting bracket 130 is fixedly arranged on the side of the first conveyor belt 100. The support rod 120 is fixedly arranged on the adjusting bracket 130. The adjusting bracket 130 is used to adjust the length of the support rod 120. The adjusting bracket 130 can adjust the position of the guiding wall 110 to adapt to sanitary napkin packages of different sizes.

[0036] Preferably, a first baffle 340 is fixedly arranged at the output end of the second conveyor belt 300. By setting the first baffle 340, it can prevent the qualified sanitary napkin packaging products from sliding down along the second conveyor belt 300 to the ground, and the qualified sanitary napkin packaging products are collected by the staff.

[0037] The working principle in this embodiment is more specifically as follows:

[0038] The staff starts the assembly line device. The sanitary napkin packaging moves on the first conveyor belt 100. When the sanitary napkin packaging reaches the output end of the first conveyor belt 100, the first driving component 210 starts. The first air cylinder 211 drives the first pushing plate 212 to push the sanitary napkin packaging to be measured onto the electronic weighing platform 220. At this time, the second baffle 213 blocks other sanitary napkin packaging at the output end of the first conveyor belt 100, and other sanitary napkin packaging cannot move forward. The electronic weighing platform 220 measures the weight of the sanitary napkin packaging, and then the fourth air cylinder 221 drives the third pushing plate 222 to push the sanitary napkin packaging to be measured to the central position of the electronic weighing platform 220. The second driving component 230 starts. The third air cylinder 232 drives the second pushing plate 233 to move downward until it abuts against the electronic weighing platform 220. The second air cylinder 231 drives the third air cylinder 232 to move horizontally, and then pushes the measured sanitary napkin packaging to the input end of the second conveyor belt 300. The second conveyor belt 300 drives the measured sanitary napkin packaging to move. When the measured sanitary napkin packaging reaches the sensing area of the air jet pump 310, if the weight of the measured sanitary napkin packaging reaches the standard, it smoothly passes through the sensing area and continues to move forward. When it passes through the sensing area of the counter 330, the count of the counter 330 is incremented by 1, and then it continues to move to the first baffle 340. If the weight of the sanitary napkin packaging does not reach the standard, the air jet pump 310 starts, and the nozzle of the air jet pump 310 jets air, blowing the measured sanitary napkin packaging along the side of the second conveyor belt 300 onto the storage table 320, achieving the purpose of rejecting and recycling unqualified products.

[0039] The assembly line device for weighing sanitary napkins of the present utility model is provided with a first conveyor belt 100, a weighing component 200 and a second conveyor belt 300. An air jet pump 310 is fixedly arranged on the side of the second conveyor belt 300. The air jet pump 310 blows the sanitary napkin packaging on the second conveyor belt 300 laterally, so that the assembly line device for weighing sanitary napkins can automatically reject unqualified sanitary napkin packaging products and save labor costs.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall fall within the protection scope of the present utility model.
