Description

Technical Field

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

[0002] The paper tube hopper of a household cigarette manufacturing machine is used to store paper tubes. When making cigarettes, one end of the paper tube is fitted over the tobacco discharge pipe, and the tobacco injection mechanism pushes the tobacco through the discharge pipe into the paper tube to form cigarettes.

[0003] Home cigarette making machines are smaller and more compact than commercial cigarette making machines, and typically can only produce one type of cigarette. Home cigarette making machines use paper tubes of two different lengths, but the hopper for these tubes is of a fixed length and can only hold one type of tube, thus limiting the production of cigarettes to one length. Utility Model Content

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

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the paper tube hopper of the household cigarette manufacturing machine is characterized by including a fixed hopper and a movable plate;

[0006] The bottom of the fixed chamber is provided with a discharge port;

[0007] 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.

[0008] The movable plate moves laterally between the first and second positions within the fixed chamber, with the width of the paper tube cavity in the first position being greater than the width of the paper tube cavity in the second position.

[0009] The paper tube hopper of this invention adjusts the length of the paper tube cavity by moving the movable plate laterally, making it suitable for two types of paper tubes. When the movable plate is in the first position, the width of the paper tube cavity is larger, which is suitable for longer paper tubes; when the movable plate is in the second position, the width of the paper tube cavity is narrower, which is suitable for shorter paper tubes.

[0010] Preferably, the paper tube hopper also includes a transmission assembly that moves the movable plate between the first and second positions.

[0011] The transmission assembly includes gears and racks;

[0012] The rack has two horizontally arranged racks, and the two racks are respectively connected to both ends of the movable plate.

[0013] 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.

[0014] Preferably, the gear is located on the side of the fixed compartment away from the moving plate;

[0015] The front and rear side plates of the fixed compartment are provided with slide grooves for the movement of two racks, and the racks are slidably disposed in the slide grooves. The racks are concealed and do not affect the overall shape. Moreover, the racks are used as side walls of the fixed compartment, making the structure more compact and complete.

[0016] 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.

[0017] 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.

[0018] Preferably, 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.

[0019] Preferably, the fixed chamber includes a bottom plate that is inclined downwards towards the discharge end. The section of the bottom 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 bottom plate. The paper tube is prone to losing its 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.

[0020] Preferably, the discharge end of the base plate is rotatably connected to a connecting plate;

[0021] The connection plate and the front side plate of the fixed compartment form a discharge channel;

[0022] The household cigarette manufacturing machine includes a base, and the lower end of the connecting plate is rotatably connected to the base;

[0023] The base plate is connected to a drive component that drives it to rock relative to the fixed chamber. The base plate and the connecting plate are movably connected to the base, and the drive component drives the base plate to rock relative to the fixed chamber, so that the paper tubes in the paper tube cavity move in an orderly manner toward the discharge port.

[0024] Preferably, the driving component includes a first motor and a linkage assembly; the linkage assembly 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;

[0025] 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.

[0026] Preferably, a paper feeding tube bracket is provided below the discharge port, and a paper stop is slidably disposed on the paper feeding tube bracket, which can switch between a first gear position and a second gear position.

[0027] The paper stopper is also equipped with a positioning sensor;

[0028] The gear is connected to the second motor, and both the positioning sensor and the second motor are connected to the controller. The paper stopper moves in cooperation with the moving plate. The paper tube discharged from the outlet enters the paper feeding tube bracket. The two positions of the paper stopper on the paper feeding tube bracket correspond to the two positions of the moving plate, which are suitable for paper tubes of two lengths.

[0029] 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;

[0030] 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.

[0031] When the positioning 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 desired position.

[0039] 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.

[0040] The paper tube hopper of this type of household cigarette manufacturing machine is located on the side of the tobacco injection mechanism 2. The paper tube hopper includes a fixed chamber 3 and a movable plate 4. The bottom of the fixed chamber 3 is provided with a discharge port 353. The movable plate 4 is arranged longitudinally and is located on one side of the fixed chamber 3. The space between the movable plate 4 and the side plate on the other side of the fixed chamber 3 is the paper tube cavity. In the figure, the movable plate 4 is located on the left side of the fixed chamber 3, and the space between the movable plate and the right side plate 34 of the fixed chamber is the paper tube cavity. The movable plate moves laterally between the first and second positions within the fixed chamber. 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. That is, the movable plate 4 has two lateral positions within the fixed chamber 3, one in the first position and one in the second position. 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, towards the right side plate 34, narrowing the paper tube cavity, 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.

[0041] The movement of the movable plate 4 in the first and second positions can be manual or powered. The driving force can be a cylinder, but cylinders have weak stability and are bulky. In the attached diagram, the paper tube hopper also includes a transmission assembly 42 that switches the movable plate between the first and second positions. The transmission assembly 42 includes gears 422 and racks 423. Two racks 423 are arranged laterally, and each rack 423 is connected to one end of the movable plate 4. Two gears 422 are rotatably mounted on the fixed chamber 3 via a rotating shaft. The two gears 422 mesh with the two racks 423. The rotation of the gears 422 can be driven by a motor or by a handwheel mounted on the rotating shaft for manual rotation. In this embodiment, a second motor 421 is used. The gears 422 then drive the racks 423 laterally, causing the movable plate 4 to move laterally. The meshing transmission of the gears 422 and racks 423 is stable and has a self-locking function, ensuring stable lateral movement of the movable plate 4 and keeping it in the first or second position.

[0042] There is an installation space between the paper tube hopper and the tobacco injection mechanism 2. The gear 422 is located on the side of the fixed chamber 3 away from the moving plate 4, that is, the gear 422 is located in the installation space between the paper tube hopper 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 chamber 3 are provided with slide grooves 43 for the movement of two racks 423 respectively. 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 chamber 3, making the structure more compact and complete, and making the overall size of the cigarette manufacturing machine small.

[0043] When the movable plate 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 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 3 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 3. 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 3.

[0044] The fixed chamber 3 includes a bottom plate 35, which is inclined downwards towards the discharge end. The section of the bottom 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 9 is in point contact with the bottom plate 35. The paper tube is prone to losing its 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.

[0045] To further improve the stability of paper tube discharge, the household cigarette manufacturing machine includes a base 6. 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 base plate 35 is connected to a driving component 37 that drives it to shake relative to the fixed chamber 3. The driving component 37 is mounted on the base 6. The driving component 37 drives the base plate 35 to shake relative to the fixed chamber 3, which can also be described as vibrating or shaking. 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 3 is more intense, causing the paper tubes 9 in the paper tube cavity to be discharged orderly from the discharge port 353. The driving component 37 includes a first motor and a linkage assembly; the linkage assembly includes a cam 371 and a swing member 372. The cam 371 is connected to the first motor and is a planar cam. The upper surface of the cam 371 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 against the cam surface 374. The first motor drives the planar cam 371 to rotate, and the undulating cam surface causes the cam driven member 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 3.

[0046] The connecting plate 352 and the front side plate 31 form a discharge channel 361. If the fixed chamber 3 is equipped with a door 36, the door 36 is swayed and installed below the front side plate 31 of the fixed chamber. 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 chamber 3. Then, 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 9 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.

[0047] Below the discharge port 353 is a paper feeding tube bracket 5, on which a paper stop 51 is slidably mounted, capable of switching between a first position and a second position. The paper tube discharged from the discharge port 353 enters the paper feeding tube bracket 5, which then feeds the paper tube to the loading station and places the beginning end of the paper tube over the tobacco discharge tube. The paper stop 51 blocks the end of the paper tube, preventing it from retracting during placement. The two positions of the paper stop 51 on the paper feeding 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, matching the length of the paper tube.

[0048] 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. 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. 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 limiting member 512, and the paper stop 51 stops at 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 limiting member 511, and the paper stop 51 stops at the first position.

[0049] The paper-blocking component 51 is also equipped with a positioning sensor. Both the positioning sensor and the second motor 421 are connected to the controller. The paper-blocking component 51 moves in conjunction with the moving plate 4. When the positioning 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 422 to rotate, causing the moving plate 4 to move laterally. It is preferable to have two positioning sensors, a left positioning sensor and a right positioning sensor. When the left positioning sensor detects the paper-blocking component 51, the paper-blocking component 51 is in the first position. When the right positioning sensor detects the paper-blocking component 51, the paper-blocking component 51 is in the second position. The controller sends a command to the second motor 421 based on the information collected by the positioning sensors, and the second motor 421 drives the moving plate 4 to automatically move to the matching first or second position.
