Description

Technical Field

[0001] This utility model relates to the technical field of cigarette testing equipment, specifically, to a disordered feeding device for empty cigarette tubes. Background Technology

[0002] In cigarette production, while ensuring the safety of tobacco products, the satisfaction and comfort of smokers must also be considered. Studies have shown that the intrinsic qualities of cigarettes, such as the ingredient ratios, tobacco filling density, and filling uniformity, all affect aroma quality and the release of harmful components in the smoke. Therefore, tobacco company laboratory personnel alter the ingredient ratios of tobacco products to improve the intrinsic quality of cigarettes, thereby developing new formulated tobacco products. When developing new formulated tobacco products, it is necessary to prepare cigarettes from the pre-mixed formulated tobacco for aroma testing. However, because these are experimental samples, the amount of formulated tobacco is small, making it impossible to prepare formulated cigarettes on a cigarette production line. Therefore, to more easily obtain formulated cigarettes, laboratory personnel use a cigarette-filling device to fill empty cigarette canisters with tobacco.

[0003] When filling cigarettes, empty cigarette tubes need to be fed into the cigarette dispenser, and the end of the empty cigarette tube should be directly aligned with the dispenser. Currently, there are few cigarette tube feeding devices that are compatible with cigarette dispensers. Laboratory personnel mostly manually hold the empty cigarette tubes directly and align them with the dispenser, which is time-consuming and laborious. Even if there are devices for feeding empty cigarette tubes, these devices are relatively simple and usually cannot screen the empty cigarette tubes. If the filter tip is facing the wrong direction when feeding the empty cigarette tube, it will result in the filter tip of the empty cigarette tube being directly aligned with the dispenser, thus affecting the filling process. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a disordered cigarette empty tube feeding device that can transform the disordered cigarette empty tubes into an ordered one and screen the cigarette empty tubes, preventing the filter end of the cigarette empty tube from facing the cigarette dispenser directly. This device is highly automated, reduces manual operation, and saves time and effort.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a disordered cigarette empty tube feeding device, including a vibrating plate, an empty tube transfer block, a linear module, and a baffle. The bottom of the outer end of the discharge trough of the vibrating plate is provided with an empty tube dropping notch along its length direction. The empty tube transfer block is located below the empty tube dropping notch. An empty tube receiving groove corresponding to the empty tube dropping notch is opened on the upper part of the empty tube transfer block. The linear module is located on one side of the vibrating plate and parallel to the discharge trough of the vibrating plate. The empty tube transfer block is fixedly installed on the slider of the linear module. The baffle can be moved laterally back and forth by a lateral moving mechanism to block or open the outer end of the discharge trough of the vibrating plate. A sensor is provided on one side plate of the outer end of the discharge trough of the vibrating plate for detecting the passage of cigarette empty tubes at the empty tube dropping notch. The spiral conveying trough of the vibrating plate is provided with a screening structure at the connection with the discharge trough, which only allows cigarette empty tubes with the filter tip facing inward to pass through.

[0006] Based on the above, the screening structure includes a screening notch at the end of the spiral conveying trough of the vibrating plate and an empty cylinder guide tube at the inner end of the discharge trough of the vibrating plate. The length of the screening notch is less than the length from the center of gravity of the empty cigarette cylinder to the cylinder end and greater than the length from the center of gravity of the empty cigarette cylinder to the filter tip end. The distance between the inner end of the empty cylinder guide tube and the inner end of the screening notch is less than the length of the empty cigarette cylinder.

[0007] Based on the above, the empty cylinder receiving groove is a V-shaped groove, a semi-circular groove, a rectangular groove, or a trapezoidal groove.

[0008] Based on the above, the lateral movement mechanism includes a pneumatic slide table, which is horizontally arranged on one side of the vibratory feeder and perpendicular to the discharge trough of the vibratory feeder, and the baffle is fixedly installed on the slide table of the pneumatic slide table.

[0009] Based on the above, the linear module is a ball screw type linear module.

[0010] Based on the above, the linear module is a linear motor type linear module.

[0011] Based on the above, the linear module is a synchronous belt type linear module.

[0012] Based on the above, the hollow guide tube is a square tube with a cross-section that gradually decreases from the inside to the outside.

[0013] This invention represents a substantial improvement over existing technologies. Specifically, the vibratory feeder automatically converts disordered cigarette canisters into ordered, sequentially discharging them one by one. The screening structure further filters the canisters, ensuring that only those with inward-facing filter tips are vibrated out of the feeder's discharge slot, thus preventing the filter tips from directly aligning with the cigarette dispenser. When the discharging canisters fall through the discharge notch into the receiving slot of the transfer block, the sensor detects them and sends a signal to the vibratory feeder, the pneumatic slide, and the linear module, causing the vibratory feeder to pause and the cigarette canisters to stop discharging. The pneumatic slide moves, causing the baffle to retract and open the outer end of the discharge trough of the vibratory feeder. The slider of the linear module moves the empty cigarette transfer block away from the vibratory feeder. The empty cigarette transfer block feeds the empty cigarettes to the empty cigarette positioning mechanism that works with the cigarette dispenser. After feeding, the empty cigarette transfer block returns to its original position below the empty cigarette discharge notch under the action of the slider of the linear module. The pneumatic slide moves the baffle to extend and reposition, blocking the outer end of the discharge trough of the vibratory feeder. The vibratory feeder continues to work, vibrating out the next empty cigarette to the empty cigarette transfer block. By repeating the above process, the empty cigarettes can be fed one by one, achieving a high degree of automation, reducing manual operation, and saving time and effort. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0020] like Figures 1-4As shown, the disordered feeding device for empty cigarette tubes includes a base plate 1, a vibrating plate 2, an empty tube transfer block 3, a linear module 4, and a baffle 5. The vibrating plate 2 is mounted on the base plate 1. An empty tube feeding notch 6 is provided along the length of the bottom of the discharge chute of the vibrating plate 2. The empty tube transfer block 3 is located below the empty tube feeding notch 6. An empty tube receiving groove 7 corresponding to the empty tube feeding notch 6 is provided on the upper part of the empty tube transfer block 3. The linear module 4 is located on one side of the vibrating plate 2 and... Parallel to the discharge trough of the vibratory feeder 2, the empty cigarette transfer block 3 is fixedly mounted on the slider of the linear module 4. The baffle 5 can move laterally back and forth via a lateral moving mechanism to block or open the outer end of the discharge trough of the vibratory feeder 2. A sensor 8 is provided on one side plate at the outer end of the discharge trough of the vibratory feeder 2, located at the empty cigarette dropping notch 6, for detecting the passage of empty cigarettes. The spiral conveying trough of the vibratory feeder 2 has a screening structure at the connection with the discharge trough that only allows cigarettes with the filter tip facing inward to pass through. The sensor 8 is an ultrasonic sensor or a photoelectric sensor, which is a conventional device. The baffle 5 initially blocks the outer end of the discharge trough of the vibratory feeder 2 to prevent the empty cigarettes from falling off the empty cigarette transfer block 3 due to inertial movement.

[0021] The screening structure includes a screening notch 9 at the end of the spiral conveying trough of the vibrating plate 2 and an empty cylinder guide tube 10 at the inner end of the discharge trough of the vibrating plate 2. The empty cylinder guide tube 10 is a square tube with a cross-section that gradually decreases from the inside to the outside. The length of the screening notch 9 is less than the length from the center of gravity of the empty cigarette tube to the end of the tube and greater than the length from the center of gravity of the empty cigarette tube to the filter tip end. The distance between the inner end of the empty cylinder guide tube 10 and the inner end of the screening notch 9 is less than the length of the empty cigarette tube. During operation, because the filter tip of the empty cigarette canister is relatively heavy, the center of gravity of the empty cigarette canister is not located at its center but is located to one side of the center tip. Therefore, when the empty cigarette canister moves along the spiral conveying trough of the vibrating plate 2 towards the discharge trough, the cigarette canister with the filter tip facing outward will flip over and fall off the screening gap 9 before the filter tip has completely passed the screening gap 9 due to the lack of support for its center of gravity. However, the cigarette canister with the filter tip facing inward can smoothly pass the screening gap 9 and enter the discharge trough of the vibrating plate through the empty canister guide tube 10. The empty canister guide tube 10 can prevent the cigarette canister with the filter tip facing inward from flipping over due to the loss of support for the filter tip. In this way, the empty cigarette canister is screened.

[0022] The hollow cylinder receiving groove 7 is a V-shaped groove, a semi-circular groove, a rectangular groove, or a trapezoidal groove.

[0023] The lateral movement mechanism includes a pneumatic slide 11, which is horizontally arranged on one side of the vibratory feeder 2 and perpendicular to the discharge chute of the vibratory feeder 2. The baffle 5 is fixedly installed on the slide of the pneumatic slide 11. In other embodiments, the lateral movement mechanism may also employ a hydraulic push rod, an electric push rod, or a linear motor, etc., that can drive the baffle 5 to move laterally.

[0024] The linear module 4 is a ball screw type linear module, a linear motor type linear module, or a synchronous belt type linear module.

[0025] A worktable 12 is provided on the base plate 1, located on one side of the discharge chute of the vibratory feeder 2. The linear module 4 and the pneumatic slide 11 are both mounted on the worktable 12. The pneumatic slide 11 is fixed to the worktable 12 by a support 13.

[0026] The working principle of this utility model is as follows: Empty cigarette canisters are placed in the hopper of the vibrating plate 2. The vibrating plate 2 automatically converts the disordered cigarette canisters into an ordered, sequential discharge. The screening structure filters the cigarette canisters to ensure that only those with the filter tip facing inwards can be vibrated out of the discharge slot of the vibrating plate 2, thus preventing the filter tip from directly facing the cigarette dispenser. The dislodged cigarette canisters fall through the empty canister discharge notch 6 into the empty canister receiving slot 7 of the empty canister transfer block 3. The sensor 8 detects the empty cigarette canisters and sends a signal to the vibrating plate 2, the pneumatic slide 11, and the linear module 4, causing the vibrating plate 2 to stop working and the cigarette canisters to stop moving. The pneumatic slide 11 drives the baffle 5 to retract and open the outer end of the discharge trough of the vibratory plate 2. The slider of the linear module 4 drives the empty tube transfer block 3 away from the vibratory plate 2. The empty tube transfer block 3 feeds the cigarette empty tube to the empty tube positioning mechanism that cooperates with the cigarette dispenser. After feeding, the empty tube transfer block 3 returns to its original position below the empty tube dropping notch 6 under the drive of the slider of the linear module 4. The pneumatic slide 11 drives the baffle 5 to extend and return to its original position to block the outer end of the discharge trough of the vibratory plate 2. The vibratory plate 2 continues to work and vibrates the next cigarette empty tube out to the empty tube transfer block 3. By repeating the above process, the cigarette empty tubes can be fed one by one, which is highly automated, reduces manual operation, and saves time and effort.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
