Description

Conical paper roll packaging machine Technical Field

[0001] This utility model relates to the field of tobacco filling technology, and in particular to a conical paper roll packaging machine. Background Technology

[0002] When filling cigarettes, the end of the cigarette paper is first inserted into the cigarette sleeve, and then the tobacco is poured into the cigarette paper. However, when used outdoors, pre-rolled cigarette paper is often not available, requiring on-site preparation. Because cigarette paper is very thin, manual rolling is difficult, making it hard to shape the cigarette. Furthermore, most existing cigarette papers are rolled into cylindrical structures of uniform diameter, and because their filling opening diameter is too small, it is difficult to fill the cigarette paper with tobacco.

[0060] To produce conical cigarette paper, this invention designs a turning frame and a rolling fixture. The rolling fixture has a clearance groove, and a bottom pressure roller is positioned below the clearance groove. A winding cylinder is installed on the turning frame, and both the winding cylinder and the bottom pressure roller are designed to be conical. When rolling conical cigarette paper, the turning frame is pressed down, causing the winding cylinder to press against the bottom pressure roller, pressing the cigarette paper between the winding cylinder and the bottom pressure roller. The winding cylinder drives the bottom pressure roller to rotate synchronously, stabilizing the cigarette paper and rolling it into a conical shape. Because the cigarette paper has some inherent adhesiveness, it can be bonded and fixed when the cigarette paper is overlapped and pressed together, thus achieving the production of conical cigarette paper.

[0061] Figures 1-4 show a first embodiment of the conical roll paper packaging machine of this utility model, including a machine base 1. A winding mechanism 2 is rotatably mounted on the left end of the upper side of the machine base 1. The winding mechanism 2 includes a flipping frame 21, a winding shaft 22, and a winding drum 23. The rear end of the flipping frame 21 is rotatably mounted on the machine base 1, and the winding shaft 22 is rotatably mounted within the flipping frame 21. The flipping frame 21 drives the winding shaft 22 to rotate around its own axis. The right end of the winding shaft 22 extends out of the flipping frame 21, and the winding drum 23 is fixedly mounted on the winding shaft 22. The winding drum 23 and the winding shaft 22 are in a transmission connection, and the winding shaft 22 drives the winding drum 23 to rotate together. In some embodiments, the winding shaft 22 is located inside the flipping frame 21, and one end of the winding drum 23 extends into the flipping frame 21 and is fixed on the winding shaft 22. In this embodiment, the winding shaft 22 extends out of the flipping frame 21, which facilitates the disassembly and replacement of the winding drum 23.

[0062] Stepper motor 24 and transmission mechanism 25 are used to drive the winding shaft 22 to rotate. Transmission mechanism 25 is fixedly installed inside the flipping frame 21, and stepper motor 24 is fixedly installed on the left side of the flipping frame 21. Stepper motor 24 drives the winding shaft 22 to rotate through transmission mechanism 25. By controlling the rotation of winding shaft 22 with stepper motor 24, the automatic rolling of cigarette paper is achieved.

[0063] The transmission mechanism 25 includes an input shaft 251 and an output shaft 252, both of which are rotatably mounted within the tilting frame 21. Gears 253 are fixedly mounted on both the input and output shafts 251 and 252, and the two gears 253 mesh with each other. The input shaft 251 is fixedly mounted on the rotor of the stepper motor 24, and the winding shaft 22 is fixedly mounted on the output shaft 252. Through gear meshing, the stepper motor 24 can drive the output shaft 252 to rotate, thereby ensuring the stable rolling of the cigarette paper.

[0064] In this embodiment, the right end of the input shaft 251 extends out of the flipping frame 21, and a winding handle 6 is fixedly installed on the right end of the input shaft 251. When there is no power connection, the stepper motor 24 cannot work. At this time, the winding handle 6 can be used to control the rotation of the input shaft 251. When the input shaft 251 rotates, the output shaft 252 can be stably rotated through the gear 253, thereby ensuring that cigarette paper can be rolled stably and effectively even when there is no power connection outdoors.

[0065] A pressing handle 16 is fixedly installed on the front side of the flipping frame 21, which facilitates the pressing down and lifting of the flipping frame 21. It should be noted that the specific location of the pressing handle 16 is not limited to the front side of the flipping frame 21, but can also be located on the left or right side of the flipping frame 21.

[0066] In some embodiments, as shown in Figures 5 and 6, the pressing handle 16 is a folding handle structure, including a rod 1601 and a rotating head 1602, with the rotating head 1602 fixed to the flip frame 21. The rod 1601 is cylindrical, with a knurled surface in the middle section for anti-slip and aesthetic purposes. The rotating head 1602 has a recessed groove 1603, and the rod 1601 is movably mounted on the rotating head 1602. With the aid of the recessed groove 1603, the pressing handle 16 has two modes: a retracted mode and an unfolded mode. In the unfolded mode, the axis of the rod 1601 is collinear with the axis of the rotating head 1602, allowing the pressing handle 16 to press down and lift the flip frame 21. In the retracted mode, the axis of the rod 1601 is perpendicular to the axis of the rotating head 1602, folding the rod 1601 and bringing it close to the outer surface of the flip frame 21. By designing the press handle 16 as a folding handle structure, it is easy to store and saves space in the packing machine.

[0067] A fixed hinge 110 is fixed to the left rear side of the machine base 1, and a movable hinge 120 is fixed to the rear side of the tilting frame 21. The rotational engagement between the winding mechanism 2 and the machine base 1 is achieved through the fixed hinge 110 and the movable hinge 120. Specifically, as shown in Figure 7, the fixed hinge 110 has two spaced-apart first flanges 111, each with a first shaft hole 112 and a limiting groove 113, forming a first locking gap 114 between the two first flanges 111. As shown in Figure 8, the bottom of the movable hinge 120 has two second flanges 121, each with a second shaft hole 122 and a pin hole 123, forming a second locking gap 124 between the two second flanges 121. The first shaft hole 112 and the second shaft hole 122 are fitted together, and the limiting groove 113 and the pin hole 123 are fitted together. Specifically, two first flanges 111 are engaged within the second locking gap 124, with the side surfaces of the first flanges 111 abutting against the side surfaces of the second flanges 121. Rotating shafts are threaded through the two first shaft holes 112 and the two second shaft holes 122, enabling the tilting frame 21 to rotate relative to the machine base 1. A limiting screw passes through the pin hole 123 and extends into the limiting groove 113, limiting the rotation of the tilting frame 21 relative to the machine base 1. In this embodiment, a torsion spring is also installed on the rotating shaft located within the first locking gap 114. Under the action of the torsion spring, the fixed hinge 110 always maintains a certain angle with the movable hinge 120. Under the action of external force, the movable hinge 120 can rotate relative to the fixed hinge 110, and is limited by the limiting screw and the limiting groove 113.

[0068] In some embodiments, the diameter of the gear 253 on the input shaft 251 is larger than the diameter of the gear 253 on the output shaft 252, which can achieve accelerated transmission and increase the efficiency of rolling thin paper.

[0069] In some embodiments, a start switch 7 is embedded on the upper side of the flipping frame 21. The start switch 7 is electrically connected to control the operation of the stepper motor 24. When the paper is rolled by electric control, the start switch 7 can be used to control the stepper motor 24 to work, thereby achieving the effect of one-click rolling.

[0070] A paper roll fixture 3 is installed on the machine base 1. The upper surface of the paper roll fixture 3 has a clearance groove 4, and a bottom pressure roller 5 is located below the clearance groove 4. The upper end of the bottom pressure roller 5 is fitted into the clearance groove 4 with a clearance fit. The clearance groove 4 cooperates with the winding drum 23, so that when the flipping frame 21 is pressed down, the winding drum 23 can press against the bottom pressure roller 5 for transmission. That is, the flipping frame 21 has a first position and a second position. In the first position, the winding drum 23 presses against the bottom pressure roller 5, and in the second position, the winding drum 23 is separated from the bottom pressure roller 5.

[0071] To produce conical cigarette paper, both the winding drum 23 and the bottom pressure roller 5 are conical with their bottoms facing the turning frame 21. Referring to Figure 2, the winding drum 23 and the bottom pressure roller 5 have a conical structure that is wider on the left and narrower on the right. However, this is not a limitation; the winding drum 23 can also be conical, while the bottom pressure roller 5 can be cylindrical.

[0072] In some embodiments, the right end of the winding cylinder 23 is formed with a mounting slot 19, which includes an arc-shaped oblique section 191, a horizontal straight section 192, and a flange section 193, wherein the cut depth of the straight section 192 is greater than the cut depth of the flange section 193. By providing the mounting slot 19, a cigarette holder can be installed at this position before the paper is rolled, thereby facilitating cigarette forming.

[0073] In some embodiments, the top edge of the bottom pressure roller 5 is arranged parallel to the upper surface of the paper rolling fixture 3, making it more efficient to roll the thin paper into a conical cylinder, thereby facilitating the subsequent filling of tobacco.

[0074] As shown in Figure 9, when rolling cigarette paper, the thin paper in a flat state is placed on the rolling fixture 3. At this time, the thin paper covers the clearance groove 4. Then, the flipping frame 21 is manually controlled to press down, so that the winding drum 23 presses on the bottom pressure roller 5. At this time, the thin paper will be pressed between the winding drum 23 and the bottom pressure roller 5. The winding shaft 22 drives the winding drum 23 to rotate. When the winding drum 23 rotates, it will press on the bottom pressure roller 5, thereby driving the bottom pressure roller 5 to rotate synchronously. This can effectively stabilize the thin paper and roll it into the shape of cigarette paper. Since the cigarette paper has some adhesiveness, it can be glued and fixed when the cigarette paper is overlapped and pressed, which is convenient for the forming of cigarette paper.

[0075] Referring to Figures 1 and 10, to make cigarette paper rolling more convenient and efficient, the upper surface of the paper rolling fixture 3 is formed with several first vacuum suction holes 12, and a vacuum chamber 13 is formed inside the paper rolling fixture 3. The bottom end of the first vacuum suction holes 12 leads into the vacuum chamber 13. A vacuum pump is fixedly installed inside the machine base 1. The vacuum pump is connected to the vacuum chamber 13 through an air pipe and an air pipe connector, and draws air from the vacuum chamber 13. When the thin paper is placed on the paper rolling fixture 3, it can be held in place by the first vacuum suction holes 12, preventing the thin paper from shifting before and after rolling, and effectively reducing the generation of defective products. It should be noted that the position of the air pipe connector connecting to the vacuum chamber 13 is not limited, but it is preferable to open a slot at the bottom of the paper rolling fixture 3 for installing the air pipe connector, which facilitates processing and the layout of the air pipe.

[0076] Because the adhesion rate between the winding drum 23 and the bottom pressure roller 5 at the rear end (away from the flipping frame 21) is not as good as that at the front end, it is preferable that the aperture of the first vacuum suction hole 12 gradually decreases from the adjacent mounting position 19 to the distance away from the mounting position 19. This makes the aperture of the first vacuum suction hole 12 adjacent to the mounting position 19 larger than that of the first vacuum suction hole 12 away from the mounting position 19. When the paper is adsorbed, the suction force of the paper near the cigarette holder is greater, which facilitates cigarette forming and reduces the generation of defective products.

[0077] For large rolls of paper, when laid on the paper roll fixture 3, all the first vacuum suction holes 12 are covered by the paper, resulting in strong suction force. For small rolls of paper, some of the first vacuum suction holes 12 are exposed, acting as air vents and reducing the suction force. Therefore, it is possible that the suction force is suitable for small rolls of paper, but too strong for large rolls, making it difficult to move the rolls. Therefore, in some embodiments, to effectively adjust the suction force of the first vacuum suction holes 12 to accommodate rolls of different sizes, the area of ​​the paper roll fixture 3 adjacent to the mounting slot 19 is designed with a single row of first vacuum suction holes 12, while the area away from the mounting slot 19 is designed with a double row of first vacuum suction holes 12. That is, the front end has a double row of suction holes, and the rear end has a single row of suction holes. In some embodiments, air vents can also be provided on the side wall of the paper roll fixture 3 to adjust the suction force for large rolls of paper.

[0078] A bottom pressure roller fixing assembly is installed on the machine base 1. This assembly includes a pressure roller fixing seat 8 and a pressure roller movable seat 9. The pressure roller fixing seat 8 is fixedly installed on the machine base 1, and the pressure roller movable seat 9 is slidably installed on it. The specific structure of the sliding installation is not limited. For example, the pressure roller movable seat 9 can be bolted to the pressure roller fixing seat 8, and the distance between the pressure roller movable seat 9 and the clearance groove 4 can be adjusted by adjusting the bolt's locking position. A pressure roller swing arm 10 is fixedly installed on the front side of the pressure roller movable seat 9. Side plates 11 are fixedly installed on both ends of the pressure roller swing arm 10, and the bottom pressure roller 5 is rotatably fitted between the two side plates 11. By sliding the pressure roller movable seat 9, its installation position can be adjusted, allowing for fine-tuning of the bottom pressure roller 5's position, thereby fine-tuning the effect of rolling thin paper and facilitating practical use.

[0079] As shown in Figure 11, this embodiment also includes a groove 31 at the bottom of the paper roll fixture 3. The groove 31 communicates with the clearance groove 4, and the bottom pressure roller fixing assembly is located within the groove 31. The bottom pressure roller fixing assembly extends at least partially below the clearance groove 4 to install the bottom pressure roller 5 below the clearance groove 4. With this configuration, the bottom pressure roller 5 can be easily replaced and maintained simply by removing the paper roll fixture 3 from the machine base 1.

[0080] An adjusting bolt 14 is fixedly installed on the machine base 1. The height of the adjusting bolt 14 is adjustable, for example, by rotating it to control its height. The front end of the bottom side of the flipping frame 21 has a right-angle notch 15 formed. When the flipping frame 21 is in the first position, the top of the adjusting bolt 14 abuts against the right-angle notch 15. Since the flipping frame 21 presses down on the top of the adjusting bolt 14, the pressure of the winding drum 23 on the bottom pressure roller 5 can be controlled by adjusting the height of the adjusting bolt 14, thus facilitating the winding of thin paper of different thicknesses.

[0081] Anti-slip rubber posts 17 are fixedly installed at all four ends of the bottom side of the machine 1, which can play an anti-slip technical role and allow the machine 1 to be placed stably on the table or other flat surface.

[0082] A counter 18 is fixedly installed at the rear end of the upper side of the machine base 1. The counter 18 is tilted and electrically connected to the stepper motor 24. It can count the number of rolls of thin paper and is convenient for counting.

[0083] In summary, this embodiment achieves the production of conical cigarette paper by designing clearance grooves on the paper rolling fixture and making the winding cylinder and bottom pressure roller conical. During rolling, the winding cylinder presses against the bottom pressure roller, utilizing the self-adhesive properties of the cigarette paper. Furthermore, a first vacuum suction hole is provided on the paper rolling fixture to hold the paper in place, thereby improving the quality of the conical cigarette paper.

[0084] Figures 12-14 show a second embodiment of the conical paper roll packaging machine of this utility model. The following mainly focuses on the differences between the second embodiment and the first embodiment, and will describe the second embodiment in detail.

[0085] In this embodiment, the winding shaft 22 is a negative pressure tube 170, as shown in Figure 15. The negative pressure tube 170 has a first air chamber 171 extending along its axis. An air pipe connector 172 is connected to the end of the negative pressure tube 170 opposite to the paper winding fixture 3, and the air pipe connector 172 communicates with the first air chamber 171. As shown in Figure 16, a plurality of second vacuum suction holes 231 are provided on the winding drum 23, and these holes are spaced apart along the axial direction of the winding drum 23. The second vacuum suction holes 231 are preferably located at the edge of the bottom of the winding drum 23, allowing the edges of the thin paper to be directly adsorbed during winding. A second air chamber 232 extending along its axis is provided inside the winding drum 23. The first air chamber 171 communicates with the second air chamber 232, and the second air chamber 232 communicates with the second vacuum suction holes 231. An air pipe is provided inside the flipping frame 21. An air pump is connected to the first end of the air pipe, and the second end of the air pipe is connected to the air pipe connector 172. When a flat piece of thin paper is placed on the paper roll fixture 3, the edge of the paper is located between the winding drum 23 and the bottom pressure roller 5. Air is drawn from the second vacuum suction hole 231 through the air pipe, air pipe connector 172, first air chamber 171, and second air chamber 232 by the air pump, so that the edge of the paper is adsorbed on the second vacuum suction hole 231, which can effectively reduce the generation of defective products.

[0086] Because the adhesion rate between the winding drum 23 and the bottom pressure roller 5 at the rear end (far from the flipping frame 21) is not as good as that at the front end, the end of the winding drum 23 furthest from the flipping frame 21 is designated as the far end, and the end of the winding drum 23 closest to the flipping frame 21 is designated as the near end. Preferably, the diameter of the second vacuum suction hole 231 gradually increases from the near end to the far end. This makes the diameter of the second vacuum suction hole 231 at the far end larger than that at the near end, and the diameter of the second vacuum suction hole 231 near the cigarette holder is even larger. When the paper is being drawn in, the suction force of the paper near the cigarette holder is greater, which facilitates cigarette forming and reduces the generation of defective products.

[0087] A retainer 173 is provided at one end of the negative pressure tube 170 near the paper roll fixture 3. A locking nut 174 is threaded onto the retainer 173. The winding drum 23 is inserted into the retainer 173 and is tapered to fit with the negative pressure tube 170. When it is necessary to change to a different specification of winding drum 23, simply loosen the locking nut 174 to achieve a quick replacement of the winding drum 23.

[0088] As shown in Figure 17, the clearance groove 4 includes an arc-shaped first groove 41 and a conical second groove 42. The first groove 41 engages with the locking nut 132, and the second groove 42 engages with the winding drum 23. When the winding drum 23 presses against the bottom pressure roller 5, part of the locking nut 174 extends into the first groove 41, and part of the winding drum 23 extends into the second groove 42. In the first embodiment, the clearance groove 4 also has a first groove 41 and a second groove 42. Since the winding shaft 22 protrudes from the right end of the flipping frame 21, when the winding drum 23 presses against the bottom pressure roller 5, part of the winding shaft 22 extends into the first groove 41.

[0089] This embodiment also includes a display device 140. The rear end of the machine base 1 has an inclined rear wall 150, on which an adjustment assembly 160 is fixed. The display device 140 is mounted on the adjustment assembly 160. As shown in Figure 18, the adjustment assembly 160 is a hinge structure, including a first fixing member 161 and a second fixing member 162. A hinge member 163 is installed between the first fixing member 161 and the second fixing member 162. The hinge member 163 is rotatably engaged with both the first fixing member 161 and the second fixing member 162, thereby adjusting the tilt angle of the display device 140 and allowing the display device 140 to be pulled closer or pushed further away. The hinge member 163 has a hollow structure, facilitating the passage of signal and power cables within it, resulting in a more aesthetically pleasing overall appearance.

[0090] In some embodiments, an adjustment base 164 is fixed to the rear wall 150, as shown in FIG19. The adjustment base 164 has two first protrusions 1641, each with a through hole, as shown in FIG20. The back of the display device 140 has two second protrusions 1401, each with a through hole. The first protrusions 1641 and the second protrusions 1401 together constitute the adjustment assembly 160. A pin is inserted through the through holes of the first protrusions 1641 and the second protrusions 1401 to adjust the tilt angle of the display device 140. Furthermore, a cable groove 1402 is provided on the back of the display device 140 to facilitate the routing of data cables, power cables, etc. of the display device 140.

[0091] In this embodiment, the stepper motor 24 is installed inside the tilting frame 21, and the stepper motor 24 is connected to the negative pressure pipe 170 by a belt drive. The tilting frame 21 is also equipped with a bearing seat 180, which supports the negative pressure pipe 170 and ensures that the negative pressure pipe 170 can rotate smoothly.

[0092] As shown in Figure 14, a sensing device 130 is installed on the rotor of the stepper motor 24. The sensing device 130 includes a disk 131 and a sensor 132. The sensor 132 is vertically arranged, and the disk 131 is disc-shaped and can rotate with the rotor of the stepper motor 24. When the disk 131 rotates, the sensor 132 swings left and right. Two inductive switches 133 are installed side by side near the sensor 132. When the sensor 132 approaches the inductive switch 133, it can control the start and stop of the stepper motor 24. Specifically, by pressing the handle 16 to press down the flipping frame 21, the winding drum 23 is pressed against the bottom pressure roller 5, and the start switch 7 is pressed. The stepper motor 24 rotates forward, and the belt drives the negative pressure tube 170 to rotate simultaneously. At this time, the second vacuum suction hole 231 on the winding drum 23 begins to attract, and the winding work begins. When the sensor 132 approaches the inductive switch 133, the motor stops rotating, the suction action stops, and the winding work is completed. After the start switch 7 is released, the stepper motor 24 reverses, and under the action of the sensor 132, the winding drum 23 returns to the starting position. This cycle ensures that the winding drum 23 is in the same position every time it works, so that the second vacuum suction hole 231 on the winding drum 23 is always located at the bottom of the winding drum 23.

[0093] In summary, this embodiment, through the design of a flipping frame and a paper-rolling fixture, incorporates clearance grooves on the paper-rolling fixture and designs the winding drum and bottom pressure roller as conical shapes. During rolling, the winding drum presses against the bottom pressure roller, utilizing the self-adhesive properties of the cigarette paper to achieve the production of conical cigarette paper. Furthermore, a first vacuum suction hole is provided on the paper-rolling fixture, and a second vacuum suction hole is designed on the winding drum. The paper paper is held in place by the first and second vacuum suction holes, improving the quality of the conical cigarette paper.
