Description

Technical Field

[0001] This utility model relates to the field of household cigarette manufacturing machines, specifically a household cigarette manufacturing machine. Background Technology

[0002] When a household cigarette manufacturing machine makes cigarettes, one end of a paper tube is fitted over the tobacco discharge tube, and the tobacco injection mechanism pushes the tobacco through the discharge tube into the paper tube to form a cigarette.

[0003] Traditional household cigarette making machines require manual insertion of a paper tube onto the tobacco discharge tube, resulting in insufficient automation and cumbersome manual operation. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide a paper feeding tube mechanism for a household cigarette manufacturing machine.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a household cigarette manufacturing machine, characterized in that it includes a paper feeding tube mechanism and a tobacco injection mechanism, which are arranged adjacent to each other;

[0006] The tobacco injection mechanism includes a tobacco discharge pipe and an injection component that pushes shaped tobacco through the tobacco discharge pipe.

[0007] The paper feeding tube mechanism includes a material bin, a paper feeding tube bracket, and a first drive component.

[0008] The hopper is provided with a discharge port, which is equipped with a movable paper stop plate, and the paper stop plate moves in coordination with the paper feeding tube bracket.

[0009] - The paper feeding tube bracket is located below the discharge port. The first driving component drives the paper feeding tube bracket to reciprocate between the paper receiving station and the material loading station. The paper feeding tube bracket is open at the end facing the tobacco discharge tube, and the other end of the paper feeding tube bracket is provided with a paper stop.

[0010] The paper feeding tube bracket is located at the loading station, with one end of the paper tube on the paper feeding tube bracket fitted over the tobacco discharge tube.

[0011] The paper feeding tube bracket receives paper at the paper receiving station. The paper tube in the hopper is discharged from the outlet and received by the paper feeding tube bracket. After receiving the paper, the paper feeding tube bracket moves to the loading station. The paper stop plate blocks the outlet to prevent the paper tube in the hopper from being discharged. The paper feeding tube bracket moves to the loading station so that one end of the paper tube is fitted over the tobacco discharge tube. The paper stop block the other end of the paper tube to prevent the paper tube from retracting during the fitting process, so that the fitting operation is completed smoothly. After the paper feeding is completed, the paper feeding tube bracket returns to the paper receiving station. The injection component pushes the formed tobacco, so that the formed tobacco passes through the discharge tube and enters the paper tube, realizing cigarette production.

[0012] Preferably, the loading station is located in front of the paper receiving station, and the paper feeding tube bracket moves between the paper receiving station and the loading station in an arc-shaped path.

[0013] The first driving component drives the paper feed tube bracket to swing back and forth. The first driving component includes a first linkage component and a driving component.

[0014] The first linkage component includes a first link and a second link arranged in parallel. One end of the first link and the second link are rotatably connected to the paper feeding tube bracket, and the other end of the first link and the second link are rotatably connected to the base. The rotation points at both ends of the first link and the second link form a parallelogram. The first link and the second link are connected to a driving component that drives them to swing.

[0015] The paper stop plate is linked with the paper feeding tube bracket. The driving component causes the paper feeding tube bracket to oscillate back and forth between the paper receiving station and the material loading station through the first linkage component, realizing translation in an arc-shaped path. Tobacco powder is abundant, and the transmission structure such as tracks, gears and racks is affected by the powder and is prone to failure. The parallelogram linkage transmission structure of this utility model has stable transmission, is not affected by dust, and has a long service life.

[0016] Preferably, the paper stop plate and the paper feed tube bracket are separately arranged, and the first driving component drives the paper stop plate to translate.

[0017] When the paper feed tube bracket receives paper, the paper stop plate moves horizontally to make way, and the paper feed tube bracket is aligned vertically with the discharge port; when the paper feed tube bracket feeds paper, the paper stop plate moves horizontally to the discharge port and blocks the discharge port.

[0018] The paper-blocking plate is clamped between the base and the first connecting rod and the second connecting rod, and the bottom surface of the paper-blocking plate is provided with a first groove and a second groove;

[0019] The first connecting rod and the second connecting rod are rotatably connected to the paper feed tube bracket via the first shaft and the second shaft, respectively. The first shaft is placed in the first groove, and the second shaft is placed in the second groove. The paper stop plate is movable, with a compact structure that is easy to install and disassemble. Moreover, it is driven by the first linkage component, reducing the use of driving components and lowering equipment costs.

[0020] The first linkage component is disposed on the lower surface of the base, the lower surface of the base is provided with a groove for the paper-blocking plate to move, the paper-blocking plate is placed in the groove, and the upper surface of the paper-blocking plate is provided with a first pin and a second pin.

[0021] The base is rotatably equipped with a third link and a fourth link, which are arranged in parallel and each has a first insertion hole and a second insertion hole. The first pin and the second pin are inserted into the first insertion hole and the second insertion hole, respectively. The rotation points at both ends of the third link and the fourth link form a parallelogram. The groove provides an independent space for the paper stop plate, facilitating its installation and movement. The parallelogram-shaped link structure ensures stable transmission, is unaffected by dust, and also guides the translation of the paper stop plate.

[0022] Preferably, the hopper includes a bottom plate, the first driving component drives the bottom plate to vibrate, and the first driving component further includes a second linkage component;

[0023] The driving component is a first motor;

[0024] The first linkage component also includes an eccentric shaft connected to a first motor. The eccentric shaft has an eccentric protrusion, and the first connecting rod has a cam groove into which the eccentric protrusion is placed. The first motor drives the eccentric shaft to rotate, and the eccentric protrusion pushes the first connecting rod within the cam groove, causing the first connecting rod to swing. When the eccentric protrusion slides within the cam groove, the first connecting rod remains stationary, at which point the paper feed tube holder receives paper at the paper receiving station. The cooperation between the eccentric protrusion and the cam groove ensures that the motor rotates in the same direction, eliminating the need for alternating forward and reverse rotation. This results in higher motor accuracy and precise positioning of the paper feed tube holder, especially crucial at the loading station where precise positioning of the paper feed tube holder ensures the paper tube is accurately fitted onto the tobacco discharge tube.

[0025] The second linkage component includes a cam and a swing element. The upper surface of the cam is a continuous undulating cam surface. The cam is connected to the first motor.

[0026] The swinging component is rotatably mounted on the base. The end of the base plate away from the discharge end is rotatably connected to the swinging component. The swinging component is provided with a cam driven component, which is placed on the cam surface. The swinging component is also connected to a second torsion spring that presses the cam swinging component against the cam surface.

[0027] The second linkage component is disposed on the upper surface of the base, and the cam is coaxially arranged with the eccentric shaft. The structure is reasonably and compactly arranged, making the whole machine smaller.

[0028] Preferably, the hopper includes a fixed hopper and a movable plate;

[0029] The discharge port is located at the bottom of the fixed compartment;

[0030] The movable plate is arranged longitudinally and is located on one side of the fixed compartment. The space between the movable plate and the side plate on the other side of the fixed compartment is a paper tube cavity.

[0031] The movable plate moves laterally between its first and second positions within the fixed chamber. The width of the paper tube cavity when the movable plate is in its first position is greater than the width of the paper tube cavity when it is in its second position. The hopper adjusts the length of the paper tube cavity by moving the movable plate laterally, accommodating two different paper tube lengths. When the movable plate is in its first position, the width of the paper tube cavity is larger, suitable for longer paper tubes; when the movable plate is in its second position, the width of the paper tube cavity is narrower, suitable for shorter paper tubes.

[0032] The paper stop is slidably mounted on the paper feed tube bracket, and the paper stop moves between a first position and a second position. The two positions of the paper stop on the paper feed tube bracket correspond to the two positions of the moving plate, and are suitable for paper tubes of two lengths.

[0033] Preferably, the hopper also includes a transmission assembly that allows the movable plate to switch between the first and second positions.

[0034] The transmission assembly includes gears and racks;

[0035] The rack has two horizontally arranged racks, and the two racks are respectively connected to both ends of the movable plate.

[0036] The gears are provided in pairs and are rotatably mounted on the fixed compartment via a rotating shaft. Each gear meshes with a rack. The gear-rack meshing transmission is stable, ensuring balanced and stable lateral movement of the moving plate, while occupying minimal space.

[0037] The gear is located on the side of the fixed compartment away from the moving plate;

[0038] The front and rear side plates of the fixed compartment are provided with grooves for the movement of two racks, which are slidably disposed within the grooves. The racks are discreetly positioned, do not affect the overall shape, and function as side walls of the fixed compartment, resulting in a more compact and complete structure.

[0039] Preferably, the movable plate is rotatably connected to a swing plate, and the swing plate is located on the other side of the movable plate opposite to the paper tube cavity. Limiting pins are installed at both ends of the swing plate. Guide grooves are provided on the front and rear side plates of the fixed compartment, and the limiting pins are inserted into the guide grooves.

[0040] When the movable plate moves laterally, the limiting pin moves along the guide groove, and the swing plate swings relative to the movable plate. When the movable plate is in the second position, there is a certain gap between the movable plate and the fixed compartment. At this time, the swing plate swings upward to a horizontal state, blocking the gap between the movable plate and the fixed compartment, which not only makes the appearance more aesthetically pleasing, but also prevents foreign objects from entering.

[0041] The fixed compartment is equipped with a compartment door, which is sway-mounted below the front side plate of the fixed compartment. The compartment door is connected to a first torsion spring, and the elastic force of the first torsion spring causes the compartment door to press against the fixed compartment. When the paper tube at the discharge port is blocked, pulling the compartment door causes it to swing forward, opening the compartment door and exposing the discharge port, making it convenient for the user to clean the paper tube at the discharge port.

[0042] Preferably, the fixed bin includes a bottom plate, which is inclined downward toward the discharge end;

[0043] The section of the base plate near the discharge end is the discharge section, which is arc-shaped. When the inclined paper tube is in the arc-shaped discharge section, the paper tube is in point contact with the base plate. The paper tube is prone to losing balance and swinging under the action of gravity, causing it to be stacked horizontally on the paper tube below or discharged from the discharge port.

[0044] The bottom plate is rotatably connected to a connecting plate at its discharge end;

[0045] The connection plate and the front side plate of the fixed compartment form a discharge channel;

[0046] The lower end of the connecting plate is rotatably connected to the base;

[0047] The first driving component drives the base plate to shake; the base plate and the connecting plate are movably connected to the base, and the driving component drives the base plate to shake relative to the fixed chamber, so that the paper tube in the paper tube cavity moves in an orderly manner toward the discharge port.

[0048] The first driving component includes a driving element and a second linkage component. The driving element is a first motor. The second linkage component includes a cam and a swing element. The cam is connected to the first motor, and the upper surface of the cam is a continuous undulating cam surface.

[0049] The end of the base plate away from the discharge end is rotatably connected to the swing member, which is also rotatably connected to the base. The swing member is provided with a cam passive member, which is placed on the cam surface. The swing member is also connected to a second torsion spring that presses the swing member against the cam surface.

[0050] Preferably, the paper feed tube bracket is provided with a left limiting member and a right limiting member to restrict the paper stop member from moving laterally on the paper feed tube bracket;

[0051] The paper stopper is connected to a third torsion spring, and the elastic force of the third torsion spring causes the paper stopper to press against the left or right limiting member.

[0052] The paper-blocking component is also equipped with a first sensor to collect the movement of the paper-blocking component into position. The gear is connected to a second motor. Both the first sensor and the second motor are connected to a controller. The paper-blocking component moves in cooperation with the moving plate.

[0053] When the first sensor detects that the paper stop has moved into position, it sends the information to the controller. The controller then sends a command to the second motor, which drives the gears to rotate, causing the moving plate to move laterally. When the paper stops at the required position, the second motor drives the moving plate to move to the corresponding paper stop, automatically matching the paper.

[0054] The first driving component includes a second sensor for collecting the starting position of the paper feed tube holder, and the second sensor and the first driving component are connected to the controller;

[0055] When the second sensor detects that the paper feed tube holder is in position, the first drive component stops operating.

[0056] Preferably, the tobacco injection mechanism further includes a frame, a forming plate, and a second driving component. The second driving component drives the injection part to move laterally and repeatedly on the frame. The second driving component also drives the forming plate to move longitudinally and reciprocally relative to the injection part on the frame. The forming plate moves in cooperation with the injection part.

[0057] The second driving component includes a third motor, a transmission gear set, a swing arm, a first guide member, and a second guide member.

[0058] The transmission gear set includes a partially meshing first gear and a second gear, both of which are sector gears and are rotatably mounted on the frame. The first gear is connected to a third motor, and the second gear is rotatably connected to a movable plate. The movable plate is rotatably connected to a forming pressure plate.

[0059] The first guide member is arranged longitudinally, and the forming plate moves longitudinally along the first guide member;

[0060] The second guide is arranged laterally, and the injection part is slidably disposed on the second guide;

[0061] The swing arm is oscillatingly mounted on the frame and connected to the injection molding part. The first gear is provided with a linkage block that drives the swing arm to oscillate. The swing arm is provided with a third groove, and the linkage block extends into the third groove.

[0062] The second driving component also includes a third sensor for collecting the paper tube's position, and the third sensor and the third motor are connected to the controller;

[0063] When the third sensor collects information about the paper tube being in position on the tobacco discharge pipe, the third motor starts. Attached Figure Description

[0083] The following description, in conjunction with the accompanying drawings, details the embodiments of this utility model and their working principles. (See attached figures) Figure 1 The X-axis is horizontal, also representing the left-right direction; the Y-axis is vertical, also representing the front-back direction; and the Z-axis is vertical, also representing the up-down direction.

[0084] This type of household cigarette manufacturing machine includes a paper feeding tube mechanism 1 and a tobacco injection mechanism 2, which are arranged adjacent to each other; in the figure, the paper feeding tube mechanism 1 is on the left and the tobacco injection mechanism 2 is on the right.

[0085] The tobacco injection mechanism 2 includes a tobacco discharge pipe 21 and an injection component 22 that pushes shaped tobacco through the tobacco discharge pipe 21. The paper feeding mechanism 1 includes a hopper 3, a paper feeding tube bracket 5, and a first driving component 37. The hopper 3 has a discharge port 353, and the discharge port 353 has a movable paper stop plate 7. The paper stop plate 7 moves in conjunction with the paper feeding tube bracket 5, including both integrated and separate structures. The paper feeding tube bracket 5 is located below the discharge port 353. The first driving component 37 drives the paper feeding tube bracket 5 to translate between the paper receiving station and the loading station, that is, the paper feeding tube bracket 5 moves in a plane. Figure 1 Paper feed tube bracket 5 is located at the loading station. Figure 2The paper feeding tube bracket 5 is located at the paper receiving station. The end of the paper feeding tube bracket 5 facing the tobacco discharge pipe 21 is open, and the other end of the paper feeding tube bracket 5 is provided with a paper stop 51. Since the tobacco discharge pipe 21 is on the right side, the right end of the feeding tray is open, and the paper stop 51 is located at the left end of the paper feeding tube bracket 5. The paper feeding tube bracket 5 receives paper at the paper receiving station, and the paper feeding tube bracket 5 is vertically aligned with the discharge port 353. At this time, the paper stop plate 7 moves away from the discharge port 353 to make way for the paper feeding tube bracket 5. The paper tube 9 in the hopper 3 is discharged from the discharge port 353 and received by the paper feeding tube bracket 5. After receiving the paper, the first driving component 37 drives the paper feeding tube bracket 5 to move towards the loading station. The paper stop plate 7 moves and blocks the discharge port 353 to prevent the paper tube in the hopper 3 from being discharged. The paper feeding tube bracket 5 moves to the loading station so that one end of the paper tube 9 is fitted over the tobacco discharge pipe 21, and the paper stop 51 blocks the other end of the paper tube to prevent the paper tube from retracting during the fitting process, so that the fitting operation is completed smoothly. After the paper feeding is completed, the paper feeding tube bracket 5 returns to the paper receiving station. The injection component 22 pushes the formed tobacco, so that the formed tobacco passes through the discharge pipe and enters the paper tube 9, realizing cigarette production.

[0086] Home cigarette making machines place greater emphasis on product size compared to commercial cigarette making machines. Larger products are less convenient for storage, and making home cigarette making machines more compact is a challenge in this field. The loading station is located in front of the paper receiving station (shown as the right front in the diagram). The loading station and the paper receiving station are not only close in position but also staggered. The first driving component 37 drives the paper feeding tube bracket 5 to move along an arc-shaped path between the paper receiving station and the loading station; that is, the trajectory of the paper feeding tube bracket 5's planar movement is arc-shaped. This results in a short travel distance for the paper feeding tube bracket 5, high paper feeding efficiency, and a more compact overall structure.

[0087] The first driving component 37 drives the paper feeding tube bracket 5 to reciprocate and swing. Swinging involves less movement and faster feeding speed compared to linear movement. Stable linear movement is usually achieved through structures such as tracks and racks and pinions. However, cigarette manufacturing machines produce a lot of tobacco powder, which can affect the transmission structures of tracks and racks and pinions, making them prone to failure. The first driving component 37 includes a first linkage assembly and a driving component. The first linkage assembly includes a first connecting rod 376 and a second connecting rod 378 arranged in parallel. One end of the first connecting rod 376 and the second connecting rod 378 is rotatably connected to the paper feeding tube bracket 5, and the other end is rotatably connected to the base 6. The rotation points at both ends of the first connecting rod 376 and the second connecting rod 378 form a parallelogram. The first connecting rod 376 and the second connecting rod 378 are connected to the driving component that drives them to swing. The first link 376, the second link 378, the paper feeding tube bracket 5 and the base 6 form a parallel four-bar linkage structure. The swinging of the first link 376 and the second link 378 drives the paper feeding tube bracket 5 to swing back and forth between the paper receiving station and the material loading station. The parallel four-bar linkage transmission structure is not only stable and precise, but also unaffected by dust, and has high efficiency and long service life.

[0088] When the paper stop plate 7 and the paper feed tube bracket 5 are separately installed, the first driving component 37 drives the paper stop plate 7 to move horizontally; when the paper feed tube bracket 5 receives paper, the paper stop plate 7 moves horizontally to make way, and the paper feed tube bracket 5 is vertically aligned with the discharge port 353; when the paper feed tube bracket 5 feeds paper, the paper stop plate 7 moves horizontally to the discharge port 353 and blocks the discharge port 353. See attached document. Figure 7 and 8The paper stop plate 7 is linked with the paper feed tube bracket 5. The paper feed tube mechanism 1 includes a base 6, and the paper stop plate 7 is clamped between the base 6 and the first connecting rod 376 and the second connecting rod 378. The paper stop plate 7 has a first groove 71 and a second groove 72, and is movably installed between the base plate 35 and the first connecting rod 376 and the second connecting rod 378. The first connecting rod 376 and the second connecting rod 378 are rotatably connected to the paper feed tube bracket 5 through the first shaft 375 and the second shaft 377, respectively. The first shaft 375 is placed in the first groove 71, and the second shaft 377 is placed in the second groove 72. The first linkage component not only drives the paper feed tube bracket 5 to swing in a plane, but also drives the paper stop plate 7 to translate. Compared with independent drive, it has lower cost and a simpler structure. At the same time, the paper stop plate 7 is movably set, with a compact structure and easy installation and disassembly. Because the travel distance of the paper stop plate 7 is shorter than that of the paper feed tube bracket 5, when the first connecting rod 376 and the second connecting rod 378 swing, if the first shaft 375 and the second shaft 377 slide in the first groove 71 and the second groove 72, the paper stop plate 7 will not move. When the first shaft 375 and the second shaft 377 move to the end of the first groove 71 and the second groove 72, the first shaft 375 and the second shaft 377 act on the paper stop plate 7, pushing the paper stop plate 7 to move horizontally. In this way, even if the travel distances are different, the paper stop plate 7 and the paper feed tube bracket 5 can move into place together.

[0089] The first linkage component is disposed on the lower surface of the base 6, and the lower surface of the base 6 is provided with a groove 61 for the paper-stopping plate 7 to move, and the paper-stopping plate 7 is placed in the groove 61. The groove 61 provides independent space for the paper-stopping plate 7, facilitating its installation and movement, and also guides the translation of the paper-stopping plate 7. To ensure precise transmission, the upper surface of the paper-stopping plate 7 is provided with a first pin 73 and a second pin 74; a third link 62 and a fourth link 63 are rotatably provided on the base 6, and the third link 62 and the fourth link 63 are arranged in parallel and each has a first insertion hole and a second insertion hole, respectively. The first pin 73 and the second pin 74 are inserted into the first insertion hole and the second insertion hole, respectively, and the rotation points at both ends of the third link 62 and the fourth link 63 form a parallelogram. Similarly, the parallel four-bar linkage transmission structure is not only stable and precise, but also unaffected by dust, has high efficiency, and a long service life.

[0090] The driving component is a first motor; the first linkage assembly also includes an eccentric shaft 370, which is connected to the first motor. The eccentric shaft 370 is provided with an eccentric protrusion 3710, and the first connecting rod 376 is provided with a cam groove 379. The eccentric protrusion 3710 is placed in the cam groove 379. The first motor drives the eccentric shaft 370 to rotate, and the eccentric protrusion 3710 pushes the first connecting rod 376 in the cam groove 379, causing the first connecting rod 376 to swing. When the eccentric protrusion 3710 slides in the cam groove 379, the first connecting rod 376 remains stationary. At this time, the paper feeding tube bracket 5 receives paper at the paper receiving station. The cooperation between the eccentric protrusion 3710 and the cam groove 379 allows the motor to maintain rotation in the same direction, eliminating the need for alternating forward and reverse rotation. This results in higher motor accuracy and ensures that the paper feeding tube bracket 5 is accurately positioned, especially at the loading station, where the accurate positioning of the paper feeding tube bracket 5 ensures that the paper tube is accurately fitted onto the tobacco discharge tube 21. If the motor operates in alternating forward and reverse directions, the inertia of the motor rotation will affect the accuracy of the paper feeding tube bracket 5 movement, leading to an increased paper tube insertion error rate.

[0091] The first driving component 37 includes a second sensor for acquiring the starting position of the paper feed tube holder 5. Both the second sensor and the first driving component 37 are connected to the controller. When the second sensor acquires the positioning information of the paper feed tube holder 5, the second driving component 37 stops operating. Specifically, the first motor starts and drives the paper feed tube holder 5 to swing. After the paper feed tube holder 5 completes one paper feed, it swings in the opposite direction and returns to the starting position. When the second sensor acquires the information that the paper feed tube holder 5 has returned to the starting position, the first motor stops operating, thus avoiding repeated paper feeds caused by the continuous operation of the first driving component 37. At the same time, the starting position of the paper feed tube holder 5 is accurately positioned, improving the feeding accuracy of the paper feed tube holder 5.

[0092] Because the paper tube is cylindrical, to prevent it from rolling off during transport, the feeding tray has an arc-shaped support section. The feeding tray is tilted with its opening facing upwards, and the support section is positioned lower, allowing the cylindrical paper roll to rest against it. The arc-shaped support section fits more closely to the cylindrical paper roll, preventing the paper roll from rolling out of the feeding tray's opening during transport.

[0093] The hopper 3 includes a fixed compartment and a movable plate 4, with the discharge port 353 located at the bottom of the fixed compartment. The movable plate 4 is longitudinally arranged and positioned on one side of the fixed compartment, with a paper tube cavity between the movable plate 4 and the side plate on the other side of the fixed compartment. The tobacco injection mechanism 2 is located on the right side of the hopper 3, therefore the movable plate 4 is positioned on the left side of the fixed compartment, with a paper tube cavity between the movable plate 4 and the right side plate 34 of the fixed compartment. The movable plate 4 can move laterally between its first and second positions within the fixed compartment. The width of the paper tube cavity in the first position is greater than the width of the paper tube cavity in the second position, meaning the movable plate 4 has two lateral positions within the fixed compartment: one first and one second. Figure 2 In the first position, the moving plate 4 is relatively far from the right side plate 34, resulting in a wider paper tube cavity, suitable for long paper tubes. When the paper tube is short, the moving plate 4 moves to the second position relative to the right side plate 34, narrowing the paper tube cavity, which is also suitable for short paper tubes. Figure 1 In the middle, the movable plate 4 is in the second position. This utility model can simultaneously meet the cigarette making needs of both long and short paper tubes, providing customers with dual options.

[0094] The movement of the movable plate 4 in the first and second positions can be manual or powered. Direct cylinder drive is possible, but cylinders are less stable and bulky. Alternatively, a motor combined with a linkage structure can be used to move the movable plate 4 to the first or second position. In the attached diagram, the hopper 3 also includes a transmission assembly 42 that allows the movable plate 4 to switch between the first and second positions. The transmission assembly 42 includes gears 422 and racks 423. Two racks 423 are arranged laterally, each connected to one end of the movable plate 4. Two gears are rotatably mounted on a fixed hopper via a rotating shaft. The two gears 422 mesh with the two racks 423. The gears 422 can be driven by a motor or manually rotated using a handwheel mounted on the shaft. In this embodiment, a second motor 421 is used. The gears drive the racks 423 laterally, thus moving the movable plate 4 laterally. The gear-rack 423 meshing transmission is stable and has a self-locking function, ensuring stable lateral movement of the movable plate 4 and its position in the first or second position.

[0095] There is an installation space between the hopper 3 and the tobacco injection mechanism 2. The gear is located on the side of the fixed compartment away from the moving plate 4, that is, the gear is located in the installation space between the hopper 3 and the tobacco injection mechanism 2, which makes more efficient use of space. The front side plate 31 and the rear side plate 32 of the fixed compartment are provided with slide grooves 43 for the two racks 423 to move. The racks 423 are slidably disposed in the slide grooves 43. The racks 423 are concealed and do not affect the overall shape. Moreover, the racks 423 are used as the side wall of the fixed compartment, making the structure more compact and complete, and making the overall size of the cigarette manufacturing machine small.

[0096] When the movable plate 4 is in the second position, there is a gap between the movable plate 4 and the left side plate 33 of the fixed compartment. To prevent debris from entering between them, the movable plate 4 is rotatably connected to a swing plate 41, and the swing plate 41 is located on the other side of the movable plate 4 opposite to the paper tube cavity, that is, on the side of the left side plate 33. Limiting pins 412 are installed at both ends of the swing plate 41. The front side plate 31 and the rear side plate 32 of the fixed compartment are provided with guide grooves 411, and the limiting pins 412 are inserted into the guide grooves 411. When the movable plate 4 moves laterally, the limiting pins 412 move along the guide grooves 411, and the swing plate 41 swings relative to the movable plate 4. The guide groove 411 includes a horizontal section and an inclined section. The inclined section is inclined upward toward the paper tube cavity and is connected to the horizontal section. When the moving plate 4 is in the first position, the limiting pin 412 is at the low point of the inclined section of the guide groove 411. The swing plate 41 is vertically arranged and placed between the moving plate 4 and the left side plate 33. When the moving plate 4 moves to the second position, the limiting pin 412 moves upward along the guide groove 411 and moves to the horizontal section. The swing plate 41 swings upward to a horizontal state, blocking the gap between the moving plate 4 and the fixed compartment. The horizontal section keeps the swing plate 41 in a horizontal state, which not only makes the appearance more beautiful, but also prevents foreign objects from entering between the moving plate 4 and the fixed compartment.

[0097] The fixed chamber includes a base plate 35, which is inclined downwards towards the discharge end. The section of the base plate 35 near the discharge end is the discharge section 351, which is arc-shaped. When the inclined paper tube is in the arc-shaped discharge section 351, the paper tube is in point contact with the base plate 35. The paper tube is prone to losing balance and swinging under the action of gravity, causing it to stack horizontally on the paper tubes below or be discharged from the discharge port 353. In this way, the paper tubes in the paper tube cavity can be discharged in an orderly manner. If the discharge section 351 is only an inclined surface, regardless of whether the paper tube is inclined or horizontal, the paper tube is in line contact with the inclined surface. The inclined paper tube is more likely to remain in an inclined state, which will affect the discharge of the paper tube and cause problems such as paper tube blockage.

[0098] To further improve the stability of paper tube discharge, a connecting plate 352 is rotatably connected to the discharge end of the base plate 35, and the lower end of the connecting plate 352 is rotatably connected to the base 6; the first driving component 37 drives the base plate 35 to shake relative to the fixed chamber, which can also be described as shaking or vibrating. Because the connecting plate 352 is rotatably connected to the base 6 and the base plate 35, the shaking of the base plate 35 relative to the fixed chamber is more intense, so that the paper tubes in the paper tube cavity are discharged from the discharge port 353 in an orderly manner. The driving component includes a second linkage assembly; the second linkage assembly includes a cam 371 and a swing member 372. The cam 371 is connected to a first motor. The cam is a planar cam, and the upper surface of the cam is a continuous undulating cam surface 374. The end of the base plate 35 away from the discharge end is rotatably connected to the swing member 372. The swing member 372 is also rotatably connected to the base 6. The swing member 372 is provided with a cam driven member 373, which is placed on the cam surface 374. The swing member 372 is connected to a second torsion spring that presses the swing member 372 against the cam surface 374. The first motor drives the planar cam to rotate, and the undulating cam surface 374 causes the cam driven member 373 to move up and down, that is, the swing member 372 swings up and down, causing the base plate 35 to rock relative to the fixed chamber. The paper tubes in the hopper 3 are arranged neatly and move orderly towards the discharge port 353. Furthermore, the undulating cam surface 374 is continuous; as the cam rotates continuously, the base plate 35 continuously vibrates. When the paper tube support 5 stops at the receiving station, the base plate 35 continues to vibrate under the action of the cam, ensuring the paper tubes in the hopper 3 are smoothly discharged from the discharge port 353. The second linkage component is located on the upper surface of the base 6, and the first linkage component is located on the lower surface of the base 6. These two components are positioned vertically, and the cam is coaxial with the eccentric shaft 370. The first motor simultaneously drives both the first and second linkage components, which not only saves costs but also results in a reasonable and compact structural arrangement, making the entire machine smaller.

[0099] The connecting plate 352 and the front side plate 31 form a discharge channel 361. If the fixed compartment is equipped with a door 36, the door 36 is swayed and installed below the front side plate 31 of the fixed compartment. The door 36 is connected to a first torsion spring. The elastic force of the first torsion spring causes the door 36 to press against the left and right side plates 34 of the fixed compartment. In this case, the connecting plate 352 and the door 36 form a discharge channel 361. At this time, the door 36 is set approximately vertically, and the outlet of the discharge channel 361 is the discharge port 353. The paper tubes are arranged vertically in the discharge channel 361, which facilitates stable discharge from the discharge port 353. When the paper tubes in the discharge port 353 and the discharge channel 361 become blocked, the door 36 is pulled to swing forward, opening the door 36 and exposing the discharge port 353 and the discharge channel 361, making it convenient for the user to clean the paper tubes.

[0100] The paper stop 51 is slidably mounted on the paper feed tube bracket 5, and the paper stop 51 can switch between a first position and a second position. The two positions of the paper stop 51 on the paper feed tube bracket 5 correspond to the two positions of the moving plate 4. That is, when the moving plate 4 is in the first position, the paper stop 51 is in the first position; when the moving plate 4 is in the second position, the paper stop 51 is in the second position, which matches the length of the paper tube. The paper feed tube bracket 5 is provided with a left limiting member 511 and a right limiting member 512 to restrict the lateral movement of the paper stop 51 on the paper feed tube bracket 5. The paper stop 51 is connected to a third torsion spring 513, and the elastic force of the third torsion spring 513 causes the paper stop 51 to press against the left limiting member 511 or the right limiting member 512. The two positions of the paper stop 51 on the paper tube bracket 5 are suitable for paper tubes of two lengths. When the paper stop 51 moves from the first position to the second position, it first overcomes the elastic force of the third torsion spring 513, causing the paper stop 51 to move to the right. After passing the elastic force critical point, the elastic force of the third torsion spring 513 pushes the paper stop 51 to press against the right limit member 512, and the paper stop 51 stays in the second position. Conversely, when the paper stop 51 moves to the left, the elastic force of the third torsion spring 513 causes the paper stop 51 to press against the left limit member 511, and the paper stop 51 stays in the first position.

[0101] The paper-blocking component 51 is also equipped with a first sensor to detect its movement into position. The gear is connected to a second motor 421, and both the first sensor and the second motor 421 are connected to a controller. The paper-blocking component 51 moves in conjunction with the moving plate 4. When the first sensor detects that the paper-blocking component 51 has moved into position, it sends the information to the controller. The controller then sends a command to the second motor 421, which drives the gear to rotate, causing the moving plate 4 to move laterally. It is preferable to have two first sensors: a left-position sensor and a right-position sensor. When the left-position sensor detects the paper-blocking component 51, it is in the first position; when the right-position sensor detects the paper-blocking component 51, it is in the second position. The controller sends a command to the second motor 421 based on the information detected by the first sensor, and the second motor 421 drives the moving plate 4 to automatically move to the matching first or second position.

[0102] The tobacco punching mechanism 2 further includes a frame, a forming pressure plate 25, and a second driving component 8. The second driving component 8 drives the punching component 22 to move laterally and repeatedly on the frame. The second driving component 8 also drives the forming pressure plate 25 to move longitudinally relative to the punching component 22 on the frame. The forming pressure plate 25 moves in cooperation with the punching component 22. As the forming pressure plate 25 moves toward the punching component 22, the punching component 22 remains stationary until the tobacco is formed. At this point, the forming pressure plate 25 remains stationary, and the punching component 22 moves laterally, pushing the formed tobacco into the paper tube. Tobacco forming is prior art and will not be described in detail here. The specific description focuses on how the second driving component 8 drives the movement of the forming pressure plate 25 and the punching component 22.

[0103] The second driving component 8 includes a third motor 81, a transmission gear set, a swing arm 85, a first guide member, and a second guide member 86. The transmission gear set includes a partially meshed first gear 82 and a second gear 83, both sector gears rotatably mounted on the frame. The first gear 82 is connected to the third motor 81, and the second gear 83 is rotatably connected to a movable plate 26, which is rotatably connected to a forming pressure plate 25. The first guide member is longitudinally positioned; the rotation of the second gear 83 drives the forming pressure plate 25 to move longitudinally along the first guide member via the movable plate 26. The second guide member 86 is transversely positioned, and the injection molding part 22 is slidably mounted on the second guide member 86. The swing arm 85 is oscillatingly mounted on the frame and connected to the injection molding part 22. The first gear 82 has a linkage block that drives the swing arm 85 to oscillate. The swing arm 85 has a third groove 851, into which the linkage block extends. When the first gear 82 rotates, the linkage block moves within the third groove 851. At this time, the swing arm 85 remains stationary. The first gear 82 drives the second gear 83 to rotate, causing the forming plate 25 to move longitudinally, thus forming tobacco. When the first gear 82 rotates until it disengages from the second gear 83, the linkage block acts on the swing arm 85, pushing it to swing and causing the injection part 22 to move longitudinally along the second guide 86, performing the tobacco injection operation. After the injection operation is completed, the third motor 81 drives the first gear 82 to rotate in the opposite direction, causing the injection part 22 and the forming plate 25 to reset one by one. The first guide and the second guide 86 can be guide rails, guide rods, guide grooves, etc. Because the first gear 82 and the second gear 83 are partially meshed, to prevent their meshing positions from being misaligned, the first gear 82 is equipped with a fourth toggle spring. At the end of the gear stroke of the first gear 82, the torsion arm of the fourth toggle spring acts on the second gear 83 (see attached figure). Figure 10When the first gear 82 and the second gear 83 rotate until they disengage, the torsion arm of the fourth spring presses down on the second gear 83 to prevent it from rotating back and keep it stationary. This allows the first gear 82 to maintain engagement with the second gear 83 when it rotates back to its original position, and drives the forming platen 25 to move in the opposite direction and reset. The second drive component 8 also includes a third sensor for detecting the paper tube's position. The third sensor, the third motor 81, and the controller are connected. When the third sensor detects the paper tube's position on the tobacco discharge pipe 21, the third motor 81 starts. If the third sensor does not detect the paper tube's position, the third motor 81 does not start, avoiding tobacco waste. In addition, during the injection and punching operation, to prevent the paper tube fitted outside the tobacco discharge pipe 21 from detaching, the tobacco injection and punching mechanism 2 also includes a pressure block 23 that is movable relative to the tobacco discharge pipe 21. During injection and punching, the pressure block 23 presses against the tobacco discharge pipe 21, fixing the paper tube onto the tobacco discharge pipe 21. After the injection and punching operation is completed, the pressure block 23 separates from the tobacco discharge pipe 21. The movement of the pressure block 23 can be driven by an independent power source or by the second drive component 8. (See attached image) Figure 9 The pressing block 23 is movably mounted on the frame. The second gear 83 is rotatably connected to a crank 24. The frame is provided with a third guide 87. Both the crank 24 and the pressing block 23 are slidably mounted with the third guide 87. The pressing block 23 is in front of the crank 24. The frame is provided with a torsion spring to reset the pressing block 23. The second gear 83 drives the crank 24 to move forward along the third guide 87. The crank 24 presses against the pressing block 23, causing it to press against the tobacco discharge pipe 21. At this time, the torsion spring is compressed. After the injection is completed, the second gear 83 rotates in the opposite direction, driving the crank 24 to retract and reset. The elastic force of the torsion spring causes the pressing block 23 to move in the opposite direction and reset.

[0104] The working principle of the preferred embodiment is further explained below with reference to the accompanying drawings: The user adjusts the width of the paper tube cavity of the hopper 3 according to the length of the paper tube. Taking a long paper tube as an example, the user pushes the paper stop 51 to move it to the first position. The left positioning sensor detects the paper stop 51, the second motor 421 starts, and drives the gear to rotate, so that the moving plate 4 moves laterally to the first position. The user places the long paper tube 9 into the paper tube cavity, and the width of the paper tube cavity matches the length of the paper tube. When the first motor is started, the cam rotates, and the eccentric protrusion 3710 moves within the cam groove 379. At this time, the paper tube support 5 waits to receive material at the receiving station, and the paper stop plate 7 moves aside. The cam driven component 373 moves up and down on the undulating cam surface 374, causing the base plate 35 to rock relative to the fixed chamber. Under the action of the base plate 35, the paper tubes are arranged neatly and orderly within the paper tube cavity and move toward the discharge port 353. The paper tubes enter the discharge channel 361 and fall onto the paper tube support 5. As the cam continues to rotate, the eccentric protrusion 3710 moves to the end of the cam groove 379 and pushes the first connecting rod 376 to swing, causing the paper tube support 5 to swing to the loading station and place the paper tube onto the tobacco discharge pipe 21. The first connecting rod 376 and the second connecting rod 378 also push the paper stop plate 7 to move horizontally to the discharge port 353 and block the discharge port 353. The third sensor detects the paper tube, the third motor 81 starts, the first gear 82 drives the second gear 83 to rotate, causing the crank 24 to move towards the pressure block 23 and push the pressure block 23 to press the paper tube. The second gear 83 also drives the forming plate 25 to move along the first guide to the injection part 22. The forming plate 25 squeezes the tobacco to form it. At this time, the linkage block moves in the third groove 851 of the swing arm 85. After the second gear 83 disengages from the first gear 82, the forming plate 25 stops moving, the first gear 82 continues to rotate, the linkage block moves to the end of the third groove 851 and acts on the swing arm 85, causing it to swing. The swing arm 85 drives the injection part 22 to move along the second guide 86, pushing the formed tobacco through the tobacco discharge pipe 21 into the paper tube, thus completing the cigarette making.
