Description

Technical Field

[0001] This invention relates to the field of tobacco shred feeding machine technology, specifically a tobacco shred feeding machine. Background Technology

[0002] In the automated production process of cigarettes, tobacco shreds are wrapped in cigarette paper. During this process, the tobacco shreds need to be conveyed by a tobacco shred feeder. However, the existing tobacco shred feeder uses a single spiral blade on the same side to convey the tobacco shreds, and the feeding amount of the spiral blade is fixed and cannot be adjusted.

[0003] After tobacco leaves are roasted and cut into shreds, the shredded tobacco often contains tobacco stems and tobacco flakes. The main difference between different cigarettes produced by the same cigarette factory lies in the content of tobacco stems and tobacco flakes. A high content of tobacco stems and tobacco flakes will affect the density of the tobacco after rolling. The current spiral blade design with a fixed feeding amount will cause the tobacco content in the cigarette to vary. How to deal with the quantitative feeding of cigarette raw materials with a high content of tobacco stems and tobacco flakes is an important research direction to ensure the quality of cigarettes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a tobacco shred feeder that facilitates the automatic quantitative feeding of tobacco shreds. At the same time, the flow rate of tobacco shreds can be adjusted by adjusting the volume of the feed cylinder, resulting in higher efficiency of tobacco shred feeding and higher precision of subsequent tobacco shred rolling, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tobacco feeding machine, comprising a tobacco box and a chute plate;

[0006] Tobacco box: The top opening is hinged with a cover plate. The lower part of the inside of the tobacco box is equipped with a feeding mechanism. The center of the bottom surface of the inside of the tobacco box is equipped with an arc-shaped groove that cooperates with the feeding mechanism. The middle of the left side of the tobacco box is equipped with a motor frame. The output shaft of the motor is equipped with a drive gear that cooperates with the feeding mechanism.

[0007] Slide plate: Located on the right side of the tobacco box, the slide plate has an adjustment mechanism that is slidably connected inside, and the adjustment mechanism is configured to cooperate with the discharge pipe at the right end of the tobacco box;

[0008] The front side of the tobacco box is equipped with a controller. The input end of the controller is electrically connected to an external power source, and the input end of the motor is electrically connected to the output end of the controller, which facilitates the automatic quantitative feeding of tobacco. At the same time, the flow rate of tobacco feeding can be adjusted by adjusting the volume of the feed cylinder, resulting in higher efficiency of tobacco feeding and higher precision of subsequent tobacco rolling.

[0009] Furthermore, the feeding mechanism includes a rotating sleeve, a mounting shaft, and a spiral blade. The rotating sleeve is rotatably connected to a circular hole at the lower end of the left side of the tobacco box. The left end of the outer side of the rotating sleeve is provided with a first gear that meshes with the drive gear. The mounting shaft is slidably connected to the inside of the rotating sleeve via a slide bar. The right end of the mounting shaft is provided with a spiral blade, which is located in an arc-shaped groove at the center of the bottom surface inside the tobacco box, facilitating the automatic feeding of tobacco.

[0010] Furthermore, a sealing ring is provided on the right end of the outer side of the mounting shaft. The outer side of the sealing ring contacts the inner wall of the sealing tube provided on the lower left side of the tobacco box. The mounting shaft is located inside the sealing tube. A spring is movably sleeved in the middle of the mounting shaft. The spring is located between the sealing ring and the rotating sleeve to facilitate the quantitative feeding of tobacco.

[0011] Furthermore, a limit plate is installed on the left end of the mounting shaft by bolts, which serves to limit the mounting shaft.

[0012] Furthermore, the tobacco box is symmetrically connected to a stirring shaft at the front and rear, with stirring blades evenly spaced in the middle of the stirring shaft. The inner wall of the tobacco box is evenly provided with arc-shaped grooves that cooperate with the stirring blades. A second gear is provided at the left end of the rear stirring shaft, which meshes with the drive gear. Both the left end of the front stirring shaft and the output shaft end of the motor are provided with pulleys, which are connected by belt drive to ensure smooth delivery of tobacco.

[0013] Furthermore, the adjustment mechanism includes a sliding plate and a material cylinder. The sliding plate is slidably connected to the inside of the slide plate. Material cylinders are provided in the mounting openings symmetrically arranged at the front and rear of the sliding plate. The material cylinders are all configured to cooperate with the discharge pipe at the right end of the tobacco box. A linear motor is provided in the middle of the upper surface of the slide plate, and an L-shaped frame is provided in the middle of the upper surface of the sliding plate. The L-shaped frame is fixedly connected to the moving part of the linear motor. The upper surface of the slide plate is provided with a through groove that cooperates with the L-shaped frame. The input end of the linear motor is electrically connected to the output end of the controller. The two material cylinders are used alternately, which can greatly improve the efficiency of tobacco conveying.

[0014] Furthermore, each of the outer surfaces of the material cylinder is equipped with an electric push rod at the upper end. The right end of the telescopic end of the electric push rod is equipped with a connecting frame. An adjusting screw is threaded into the threaded hole at the lower end of the connecting frame. The left end of the adjusting screw passes through the corresponding clearance opening in the middle of the right side of the material cylinder and is rotatably connected to a push plate at the end. The push plates are located inside the material cylinder on the same side. The input end of the electric push rod is electrically connected to the output end of the controller to facilitate the automatic ejection of tobacco.

[0015] Furthermore, guide rods are symmetrically provided on the right edge of the pusher plate, and guide holes that are slidably connected to the guide rods are symmetrically provided on the right side of the material cylinder and the lower end of the connecting frame, which play a guiding role in the adjustment of the pusher plate.

[0016] Furthermore, a bracket is provided in the middle of the right side of the slide plate, and the right end of the bracket is fixedly connected to the outer side of the two material cylinders respectively, so that the material cylinders are more securely fixed.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The controller controls the motor to work, and drives the rotating sleeve to rotate through the meshing of the drive gear and the first gear, which in turn causes the mounting shaft and the spiral blade to rotate. At this time, the right end of the spiral blade is located in the discharge pipe on the right side of the tobacco box. The spring can provide elastic support for the mounting shaft. The rotation of the spiral blade transports the tobacco inside the tobacco box through the discharge pipe to the corresponding material cylinder. When the material cylinder is full of tobacco, as the spiral blade rotates, the spiral blade and the mounting shaft gradually move to the left until the spiral blade moves out of the discharge pipe, thereby ensuring that the tobacco is automatically and quantitatively fed into the material cylinder.

[0019] 2. The controller controls the linear motor to move the slide forward via the L-shaped frame, causing the tobacco-filled cylinder to move forward. The empty cylinder behind the slide aligns with the discharge pipe at the bottom of the tobacco box. At this point, under the spring force, the mounting shaft and spiral blade reset to the right, pushing the tobacco into the corresponding cylinder, thus continuing to quantitatively feed the tobacco. Simultaneously, the controller controls the electric push rod at the front to move the push plate to the left via the connecting frame and adjusting screw, pushing the tobacco out of the cylinder. The two cylinders alternately feed the tobacco, greatly improving the efficiency of tobacco feeding.

[0020] 3. By rotating the lead screw, the pusher plate moves to the left under the guidance of the guide rod, thereby adjusting the volume of the material cylinder, adjusting the amount of tobacco stored inside the cylinder, and thus adjusting the flow rate of the tobacco conveying, in order to meet the production needs of different types of cigarettes.

[0021] 4. While the drive gear rotates, the second gear drives the rear stirring shaft to rotate synchronously in the opposite direction to the drive gear. At the same time, the pulley and belt drive the front stirring shaft to rotate synchronously in the same direction as the drive gear. The stirring plates in the middle of the stirring shaft rotate in opposite directions to agitate the tobacco shreds, ensuring the normal delivery of the tobacco shreds. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-4 The present invention provides a tobacco feeding machine, including a tobacco box 1 and a chute plate 7.

[0030] Tobacco box 1: A cover plate 4 is hinged to the upper opening of the tobacco box 1. Tobacco is placed inside the tobacco box 1, and the cover plate 4 is closed and secured with a snap fastener for easy sealing of the tobacco. A feeding mechanism 2 is located at the lower end of the interior of the tobacco box 1. An arc-shaped groove that mates with the feeding mechanism 2 is located at the center of the bottom surface of the interior of the tobacco box 1. A motor 5 is mounted on the middle of the left side of the tobacco box 1 via a motor frame. The output shaft of the motor 5 has a drive gear 6 that mates with the feeding mechanism 2. The feeding mechanism 2 includes... The rotating sleeve 22, mounting shaft 25, and spiral blade 26 are rotatably connected to the circular hole at the lower left side of the tobacco box 1. The left end of the outer side of the rotating sleeve 22 is provided with a first gear 221 that meshes with the drive gear 6. The mounting shaft 25 is slidably connected to the inside of the rotating sleeve 22 via a slide bar. The right end of the mounting shaft 25 is provided with a spiral blade 26, which is located in an arc-shaped groove at the center of the bottom surface inside the tobacco box 1. The right end of the outer side of the mounting shaft 25 is provided with a sealing ring 24, the outer side of which is in contact with the tobacco. The inner wall of the sealing tube located at the lower left side of the inside of box 1 contacts the mounting shaft 25, which seals the gap between the mounting shaft 25 and the sealing tube. The mounting shaft 25 is located inside the sealing tube, and a spring 23 is movably sleeved in the middle of the mounting shaft 25. The spring 23 is located between the sealing ring 24 and the rotating sleeve 22. When the motor 5 is working, the rotating sleeve 22 is driven to rotate through the meshing of the drive gear 6 and the first gear 221, which in turn causes the mounting shaft 25 and the spiral blade 26 to rotate. At this time, the right end of the spiral blade 26 is located inside the discharge pipe on the right side of the tobacco box 1. Spring 23 provides elastic support for mounting shaft 25. The rotating spiral blade 26 automatically conveys the tobacco inside the tobacco box 1 through the discharge pipe. When the external container stores a certain amount of tobacco, as the spiral blade 26 rotates, the spiral blade 26 and mounting shaft 25 gradually move to the left, and spring 23 is compressed until the spiral blade 26 moves out of the discharge pipe, thus facilitating the automatic quantitative conveying of tobacco. The left end of mounting shaft 25 is bolted with a limit plate 21, which limits the mounting shaft 25.

[0031] Slide plate 7: Located on the right side of tobacco box 1, slide plate 7 has an adjusting mechanism 3 slidably connected inside. The adjusting mechanism 3 is configured to cooperate with the discharge pipe at the right end of tobacco box 1. The adjusting mechanism 3 includes a sliding plate 31 and a material cylinder 32. The sliding plate 31 is slidably connected inside slide plate 7. Material cylinders 32 are provided in the symmetrically arranged mounting openings at the front and rear of the sliding plate 31. The material cylinders 32 are configured to cooperate with the discharge pipe at the right end of tobacco box 1. A linear motor 8 is provided in the middle of the upper surface of slide plate 7, and an L-shaped frame 311 is provided in the middle of the upper surface of sliding plate 31. The L-shaped frame 311 is fixedly connected to the moving part of the linear motor 8. The upper surface of 7 is provided with a through groove that mates with the L-shaped frame 311. Electric push rods 33 are provided at the upper end of the outer side of the material cylinder 32. A connecting frame 35 is provided at the right end of the telescopic end of each electric push rod 33. An adjusting screw 34 is threaded into the threaded hole at the lower end of each connecting frame 35. The left end of the adjusting screw 34 passes through a corresponding clearance opening in the middle of the right side of the material cylinder 32 and is rotatably connected to a push plate 341 at its end. The push plates 341 are located inside the material cylinder 32 on the same side. Guide rods 9 are symmetrically provided at the edge of the right side of each push plate 341. The right side of the material cylinder 32 and the lower end of the connecting frame 35 are symmetrical. A guide hole is provided that is slidably connected to the guide rod 9. When the material cylinder 32 corresponding to the discharge pipe is filled with tobacco, the linear motor 8 works, driving the slide plate 31 forward through the L-shaped frame 311, causing the material cylinder 32 filled with tobacco to move forward. The empty material cylinder 32 behind the slide plate 31 corresponds to the discharge pipe at the lower end of the tobacco box 1. At this time, under the elastic force of the spring 23, the mounting shaft 25 and the spiral blade 26 return to the right and push the tobacco into the corresponding material cylinder 32, thereby continuing to quantitatively feed the tobacco. The two material cylinders 32 are used alternately, which can greatly improve the efficiency of tobacco feeding. The electric push rod 33 works. The pusher plate 341 is moved to the left by the connecting frame 35 and the adjusting screw 34 to push out the tobacco inside the material cylinder 32. By rotating the adjusting screw 34, the pusher plate 341 is moved to the left under the guidance of the guide rod 9, thereby adjusting the volume of the material cylinder 32. This allows for adjustment of the amount of tobacco stored inside the material cylinder 32, and consequently, the flow rate of the tobacco. This results in higher precision in the subsequent rolling of the tobacco. A bracket 10 is provided in the middle of the right side of the slide plate 31. The right end of the bracket 10 is fixedly connected to the outer side of the two material cylinders 32, making the fixation of the two material cylinders 32 more stable.

[0032] Among them, the front side of the tobacco box 1 is equipped with a controller 15. The input end of the controller 15 is electrically connected to an external power source. The input ends of the motor 5, the electric push rod 33 and the linear motor 8 are all electrically connected to the output end of the controller 15 to ensure the normal operation of the circuit.

[0033] The tobacco box 1 is symmetrically connected to a stirring shaft 11 inside. Stirring blades 12 are evenly spaced in the middle of the stirring shaft 11. The inner wall of the tobacco box 1 is evenly provided with arc-shaped grooves that cooperate with the stirring blades 12. A second gear 13 is provided at the left end of the rear stirring shaft 11. The second gear 13 is meshed with the drive gear 6. The left end of the front stirring shaft 11 and the output shaft end of the motor 5 are both provided with pulleys. The two pulleys are connected by a belt 14. When the drive gear 6 rotates, the second gear 13 drives the rear stirring shaft 11 to rotate synchronously in the opposite direction to the drive gear 6. At the same time, the pulleys and belt 14 drive the front stirring shaft 11 to rotate synchronously in the same direction as the drive gear 6. The stirring blades 12 corresponding to the middle of the stirring shaft 11 rotate in opposite directions to agitate the tobacco and ensure the normal delivery of the tobacco.

[0034] The working principle of the tobacco feeding machine provided by this invention is as follows: Tobacco is placed inside the tobacco box 1, the cover 4 is closed and fixed with a buckle, and then the controller 15 controls the motor 5 to work. Through the meshing of the drive gear 6 and the first gear 221, the rotating sleeve 22 rotates, thereby causing the mounting shaft 25 and the spiral blade 26 to rotate. At this time, the right end of the spiral blade 26 is located inside the discharge pipe on the right side of the tobacco box 1. The spring 23 provides elastic support for the mounting shaft 25. The rotation of the spiral blade 26 feeds the tobacco inside the tobacco box 1 through... The discharge pipe delivers tobacco to the corresponding feed cylinder 32. Once the feed cylinder 32 is full, the rotation of the spiral blade 26 causes the spiral blade 26 and mounting shaft 25 to gradually move to the left until the spiral blade 26 exits the discharge pipe, ensuring a precise amount of tobacco is delivered to the feed cylinder 32. Then, the controller 15 controls the linear motor 8 to move the slide plate 31 forward via the L-shaped frame 311, causing the feed cylinder 32 filled with tobacco to move forward. The empty feed cylinder 32 behind the slide plate 31 aligns with the discharge pipe at the lower end of the tobacco box 1. At this time, the spring 23... Under the action of elastic force, the mounting shaft 25 and the spiral blade 26 reset to the right and push the tobacco into the corresponding feed cylinder 32, thus continuing to quantitatively feed the tobacco. At the same time, the controller 15 controls the electric push rod 33 on the front side to work, which drives the push plate 341 to move to the left through the connecting frame 35 and the adjusting screw 34, pushing out the tobacco inside the feed cylinder 32. By rotating the adjusting screw 34, under the guidance of the guide rod 9, the push plate 341 moves to the left, thereby adjusting the volume of the feed cylinder 32, which can regulate the amount of tobacco stored inside the feed cylinder 32. The flow rate of the tobacco shreds is adjusted by adjusting the shreds, resulting in higher rolling precision. The two feed cylinders 32 alternately transport the tobacco shreds, which can greatly improve the efficiency of tobacco shred transport. While the drive gear 6 rotates, the second gear 13 drives the rear stirring shaft 11 to rotate synchronously in the opposite direction to the drive gear 6. At the same time, the pulley and belt 14 drive the front stirring shaft 11 to rotate synchronously in the same direction as the drive gear 6. The stirring blades 12 corresponding to the middle of the stirring shaft 11 rotate in opposite directions to agitate the tobacco shreds, ensuring normal tobacco shred transport.
