Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a device for assisting stem collection and metering. Background Art

[0002] The stem and shred separation system of the cigarette making machine mainly completes the tasks of separating stems and shreds and conveying shredded tobacco. The separated stems are transported to the power workshop through pipelines for centralized collection and disposal. If too few stems are removed during the production process, it will inevitably lead to too high stem content in the cigarette, which can easily cause puncture, air leakage, and even bursting at the burning end of the cigarette, which not only affects the combustibility of the cigarette, the stability of physical measurement indicators, but also affects the sensory quality of the entire cigarette. If too many stems are removed, the tobacco content in the removed stems will be high, thereby reducing the effective utilization rate of tobacco. Therefore, the amount of stem removal needs to be reasonably controlled during the production process.

[0003] At present, the amount of stem picks rejected is detected manually by opening the cover on the rear side of the machine, starting the timer at the same time, collecting the amount of stem picks rejected for a certain period of time, and then testing the amount of stem picks rejected by weighing. This process requires 2-3 people to cooperate with each other, one person is responsible for opening the cover and collecting the stem picks, and one person is responsible for recording the time. The whole process requires manual operation, and people need to calculate the amount of stem picks rejected based on the equipment speed, collection time, and net silk content of the production brand. That is, from the beginning of collection and weighing to obtaining the amount of stem picks rejected, it takes a long time, which is time-consuming and labor-intensive. Sometimes, due to improper collection or poor cooperation, the stem picks are not collected accurately, which affects the judgment of the results. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a stem-assisted collection and metering device has the following structural relationship: it comprises a bottom plate 1, and a plurality of moving wheels 11 with brake pads are installed at the bottom of the bottom plate 1 for movement, and the moving wheels 11 make the bottom plate 1 easy to move. An L-shaped mounting plate 12 is fixedly connected to the top of the moving wheel 11, and a gripping rod 13 is installed on the side of the mounting plate 12 away from the discharge port, and the gripping rod 13 is convenient for pushing the bottom plate 1 to move.

[0026] like Figure 1-Figure 3As shown, the metering device includes a sealing mechanism 2 mounted on the mounting plate 12 for controlling the switch of the discharge port. The sealing mechanism 2 includes a slide rail 201, a slide plate 202, and a mounting frame 203. Two sets of slide rails 201 are fixedly connected to the side of the mounting plate 12 facing the bottom plate 1. Two sets of slide plates 202 are respectively slidably connected to the two sets of slide rails 201. The mounting frame 203 is fixedly connected to the side of the two sets of slide plates 202 away from the mounting plate 12. The slide rails 201 and the slide plate 202 make the movement of the mounting frame 203 stable. The sealing mechanism 2 also includes a first push rod motor 204, a moving cylinder 205, a moving plate 206, a connecting rod 207, and a baffle 208. The first push rod motor 204 is mounted on the mounting frame 203. The output end of the first push rod motor 204 faces the side away from the mounting plate 12. The hollow moving cylinder 205 is fixedly connected to the output end of the first push rod motor 204. After the first push rod motor 204 is started, it drives the moving cylinder 205 to move. The moving plate 206 is slidably connected to the moving cylinder 205, and the connecting rod 207 that passes through one end of the moving cylinder 205 is fixedly connected to the side of the moving plate 206 away from the first push rod motor 204. The connecting rod 207 drives the moving plate 206 to slide in the moving cylinder 205 when moving. The baffle 208 is fixedly connected to the end of the connecting rod 207 away from the moving plate 206, and the connecting rod 207 drives the baffle 208 to move synchronously when moving. The baffle 208 blocks the discharge port to prevent the stems from falling. The sealing mechanism 2 also includes a first spring 209, a pressure sensor 210, and a second spring 211. The first spring 209 is arranged in the moving cylinder 205 and fixedly connected to the side of the moving plate 206 close to the first push rod motor 204. The first spring 209 is used to release the elastic force so that the baffle 208 is close to the discharge port. The pressure sensor 210 is fixedly connected to the inner wall of the moving cylinder 205. The pressure sensor 210 is arranged on the side of the moving plate 206 away from the first push rod motor 204. When the baffle 208 completely leaves the discharge port, the first spring 209 releases elastic force to drive the moving plate 206 to squeeze the pressure sensor 210, so that the pressure sensor 210 sends a signal to start timing. The two ends of the multiple sets of second springs 211 are respectively fixedly connected to the mounting plate 12 and the mounting frame 203. The second spring 211 is used to continue to push the bottom plate 1 to move when the baffle 208 contacts the discharge port, so that the mounting frame 203 moves and the second spring 211 is compressed at the same time, thereby preventing the first spring 209 from being overly compressed due to pushing the bottom plate 1, and then making it difficult for the expansion and contraction of the first push rod motor 204 to drive the baffle 208 to move. The sealing mechanism 2 also includes a limit rod 212 and a limit seat 213. The two sets of limit rods 212 are symmetrically arranged on both sides of the movable cylinder 205 and are fixedly connected to the baffle 208. The two sets of limit seats 213 are respectively slidably connected to the two sets of limit rods 212. The limit seat 213 is fixedly connected to the mounting frame 203, so that the movement of the baffle 208 is smooth.

[0027] Preferably, the above metering device further includes a positioning component 3 for fixing the position of the mounting bracket 203. The positioning component 3 includes a second push rod motor 31, a pressing plate 32, and a rubber pad 33. The second push rod motor 31 is installed on the mounting bracket 203 and moves synchronously with the mounting bracket 203. The output end of the second push rod motor 31 faces upward and is fixedly connected to the pressing plate 32. The second push rod motor 31 drives the pressing plate 32 to move after starting. A rubber pad 33 is provided on the side of the pressing plate 32 away from the second push rod motor 31, so that when the pressing plate 32 approaches the mounting plate 12, the rubber pad 33 is squeezed to fix the position of the mounting bracket 203.

[0028] Further preferably, the above metering device includes a weighing component 4 provided on the top of the bottom plate 1 for weighing the discharged stem pieces. The weighing component 4 includes a weighing unit 41, a weighing pan 42, and a weighing box 43. The weighing unit 41 is installed on the top of the bottom plate 1, and the weighing pan 42 is fixedly connected to the top of the weighing unit 41. The weighing box 43 is placed above the weighing pan 42. When the baffle 208 is opened, the stem pieces at the discharge port fall into the weighing box 43, and the weighing unit 41 weighs the stem pieces. The weighing component 4 further includes a guide plate 44 and a limit plate 45. The guide plate 44 is installed at the top of the weighing box 43 near the discharge port to facilitate guiding when the stem pieces fall. The limit plate 45 is fixedly connected to the top of the weighing pan 42. The limit plate 45 is arranged in a "U" shape to facilitate placing the weighing box 43 on the weighing pan 42. A processing module 5 is also installed on the top of the bottom plate 1. The first push rod motor 204, the pressure sensor 210, the second push rod motor 31, and the weighing unit 41 are all electrically connected to the processing module 5 to achieve automatic control.

[0029] When in use, the user holds the handle 13 and pushes the bottom plate 1 to move under the action of the moving wheel 11, so that the baffle 208 approaches the discharge port. When the baffle 208 contacts the discharge port, the bottom plate 1 continues to move. At this time, the first spring 209 is compressed and the mounting frame 203 moves and squeezes the second spring 211 under the limiting action of the slide rail 201 and the slide plate 202. Then, the second push rod motor 31 is started, and the second push rod motor 31 drives the pressure plate 32 to move and squeeze the rubber pad 33, so that the position of the mounting frame 203 is fixed. When metering, the first push rod motor 204 is started to contract, and the first push rod motor 204 drives the moving cylinder 205 away from the discharge port. At this time, the first spring 209 slowly expands. When the baffle 208 just leaves the discharge port, the first spring 209 drives the moving plate 206 to squeeze the pressure sensor 210. At this time, the pressure sensor 210 senses the squeeze and sends a signal to start the timer in the processing module 5. At this time, the stalks are discharged downward from the discharge port, and fall into the weighing box 43, where they are weighed by the weighing unit 41 and fed back to the processing module 5. Then, the first push rod motor 204 is started again to cover the baffle 208 at the discharge port, and at the same time, the first spring 209 is compressed, and the moving plate 206 is away from the pressure sensor 210. The pressure sensor 210 sends a signal to stop the timing of the processing module 5. At this time, the processing module 5 calculates the time and the weight weighed by the weighing unit 41, and displays the result on the display screen on the side of the mounting plate 12.
