Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery equipment, and particularly relates to a base rod cutting device and a cutting system in aerosol generating articles. Background Art

[0002] Aerosol generating articles are cigarette products, including traditional cigarettes and heat-not-burn cigarettes. In recent years, with the development of technology and the increasing attention of consumers to new things, new cigarette products have emerged in an endless stream, and the requirements for the base rods used in cigarette products have become higher and higher.

[0003] The base rod in aerosol generating articles, that is, the base rod for cigarette products, is rod-shaped and is directly or indirectly joined to an aerosol-forming matrix (i.e., tobacco segments). Generally, the base rod in aerosol generating articles includes a filter rod with a filtering function, mainly made of cellulose acetate, which is used to filter harmful substances in the aerosol; a cooling rod with a cooling function, mainly used to cool the smoke that will enter the user's mouth; and a support rod with a supporting function, etc.

[0004] In recent years, the flexible design requirements and the pursuit of the actual effect of preparing multi-component composite base rods have made the demand for base rod composite equipment more urgent. Therefore, it is necessary to develop a forming device that is applicable to various diameter specifications and can realize the composite of base rods with different lengths according to design requirements to solve the above problems. However, the current base rod forming devices on the market are basically for production, lacking flexible devices suitable for laboratory samples.

[0005] Chinese Utility Model Patent CN217407772U discloses a cavity transparent filter rod composite device, including a feeding device 100, a hopper device 200, a cutting device 300, a conveying device 400, a distance determining device 500, and a frame 600. The feeding device 100 is provided to supply filter rod raw materials for the filter rod composite device, and by setting an adjustable plate that can be adjusted back and forth on the back of the hopper device 200, the hopper device 200 is made applicable to filter rods of different specifications and lengths, improving the versatility of this composite device and reducing the cost of purchasing new equipment. The cutting process of the filter rod is to adsorb the filter rod in the circumferential groove of the cutting hub wheel 301 through an air extraction device 303. When the cutting hub wheel 301 rotates left to the tool magazine 302 position, the filter rod is cut into rod segments of a specified length by the tool magazine 302. This Chinese Utility Model Patent cuts in the cutting hub wheel 301.

[0006] Chinese Utility Model Patent CN208657967U discloses a cigarette filter rod slitting device, which includes a frame I, a slitting device 2, a feeding hopper 3, a hopper 4, and a conveying device 5. The slitting device 2 is installed on the top of the frame I, the feeding hopper 3 is arranged above the slitting device 2, the hopper 4 is installed on the top of the feeding hopper 3, and the conveying device 5 is installed on the lower side of the slitting device 2. The cigarette filter rod automatically falls from the feeding hopper 3 into the wheel groove 18 with negative pressure of the wheel body 9 and is adsorbed in the wheel groove 18 by negative pressure. The wheel body 9 drives the filter rod to rotate with it. Since the cutting edge of the cutter 56 is located in the annular cutter groove 20 of the wheel body 9, when the filter rod is conveyed to the position of the cutter 56, the motor III 61 drives the cutter 56 to rotate and cut the filter rod. Since the cigarette filter rod is stably fixed in the wheel groove 18 on the wheel body 9 by negative pressure, it can effectively prevent the filter rod from moving during the cutting force of the cutter, resulting in uneven cut or damage to the filter rod.

[0007] When it is necessary to slit cigarette filter rods of different lengths, the wheel body 9 of different lengths can be replaced. If the length of the cigarette filter rod does not exceed 10 mm within the length of the wheel body 9, the wheel body 9 does not need to be replaced. At this time, the distance between the back plate 48 and the front baffle 45 is adjusted by adjusting the support rod 49, and at the same time, the distance between the rear baffle 25 and the cover plate 28 is adjusted to meet the length requirements of cigarette filter rods of different specifications, so as to realize the slitting processing of filter rods of different length specifications. And the two ends of the filter rod can be fixed by the back plate 48 and the front baffle 45 to realize the double fixation of the filter rod, which is convenient for the cutter to cut it.

[0008] In the prior art, when solving the problem of filter rod slitting, it mainly focuses on the practicability of small equipment for cutting small batches of filter rods, while ensuring product quality. The existing base rod slitting device of aerosol generating articles slits the base rod in a rotating drum. If it is necessary to slit base rods of different lengths, it is necessary to replace the rotating drum or adjust the mechanical structure, resulting in long time consumption, high time cost and high production cost of equipment replacement, and it cannot meet the flexible test requirements.

[0072] Adopting the above technical solution, the base rod cutting device 1 in the aerosol generating article provided by the present invention is provided with the base rod pushing part 1.3.16, which can set the pushing distance of the base rod 1.3.14 according to the target cutting length of the base rod 1.3.14, so that the base rod cutting device 1 of the aerosol generating article can realize cutting the base rod 1.3.14 into different lengths as long as the preset pushing distance is adjusted according to the target cutting length, improving the flexibility and applicability of the base rod cutting device 1 in the aerosol generating article and reducing the cost of cutting the base rod 1.3.14.

[0073] Referring to Figure 1 and in combination with Figure 15 and Figure 16 , in some possible embodiments provided by the present invention, the base rod cutting device 1 in the aerosol generating article further includes a base rod discharging unit 1.2.

[0074] In some possible embodiments provided by the present invention, the base rod discharging unit 1.2 includes a base rod rotating and conveying part for transporting the base rod 1.3.14 to the base rod fixed-length pushing unit 1.3.

[0075] Referring toFigure 17 and in combination with Figure 15 、 Figure 16 and Figure 18 , the base rod rotary conveying part includes a rotary drum 1.2.7 for conveying the base rod.

[0076] In some possible embodiments provided by the present invention, a plurality of grooves 1.2.13 opening outward are provided at intervals along the circumferential direction (such as the Q direction shown in Figure 17 ) on the outer peripheral wall of the rotary drum 1.2.7.

[0077] In some possible embodiments provided by the present invention, at least two of the plurality of grooves 1.2.13 have different widths.

[0078] Exemplarily, refer to Figure 17 , the rotary drum 1.2.7 is provided with grooves 1.2.13 of four widths (such as the first width K1, the second width K2, the third width K3, and the fourth width K4 shown in the figure). The grooves of the four widths are respectively used to accommodate the base rods 1.3.14 of ultra-fine, standard, medium, and fine specifications. Preferably, the width range of the grooves 1.2.13 of the four widths is 5.4 mm to 7.8 mm.

[0079] Exemplarily, in this embodiment, the grooves 1.2.13 are all U-shaped. In some other possible embodiments, the grooves 1.2.13 can also be V-shaped, trapezoidal, etc., as long as they are adapted to the diameter of the base rod 1.3.14 and can be used to accommodate the base rod 1.3.14.

[0080] Adopting the above technical solution, the rotary drum 1.2.7 provided with grooves 1.2.13 of different widths can be applicable to the conveyance of base rods 1.3.14 of different diameters, and realize the subsequent cutting of the base rods 1.3.14 of different diameters. That is to say, the base rod cutting device 1 in the aerosol generating article provided by the present invention is applicable to cutting base rods 1.3.14 of different diameters into different lengths, improving the applicability and flexibility of the cutting device 1. The base rod cutting device 1 in the aerosol generating article provided by the present invention does not need to replace or produce different base rod cutting devices 1 in the aerosol generating article according to the base rods 1.3.14 with different diameters, reducing the production cost of base rod cutting.

[0081] Refer toFigures 15 to 17 , in some possible embodiments provided by the present invention, the base rod rotating and conveying part further includes an arc-shaped baffle 1.2.8.

[0082] In some possible embodiments provided by the present invention, the arc-shaped baffle 1.2.8 matches the bending radian of the outer peripheral wall of the rotating drum 1.2.7, and the arc-shaped baffle 1.2.8 fits the outer peripheral wall of the rotating drum 1.2.7.

[0083] Reference Figure 17 , in some possible embodiments provided by the present invention, the top of the rotating drum 1.2.7 is the material receiving point S for receiving the base rod 1.3.14 from the upstream, the bottom of the rotating drum 1.2.7 is the material discharging point F, and the accommodated base rod 1.3.14 reaches the material discharging point F and falls onto the base rod fixed-length pushing unit 1.3. Along the circumferential direction (such as Figure 17 the Q direction shown in), the intermediate positions between the material receiving point S and the material discharging point F are the midpoints D1 and D2. The tangents of the rotating drum 1.2.7 at the midpoints D1 and D2 are vertical lines. The arc-shaped baffle 1.2.8 is located on the path of the rotating drum 1.2.7 rotating from the material receiving point S to the material discharging point F, and extends from the material discharging point F along the circumferential direction (such as Figure 17 the Q direction shown in) to at least the midpoints D1 and D2.

[0084] In this embodiment, the arc-shaped baffle 1.2.8 is arranged on the left side of the outer peripheral wall of the rotating drum 1.2.7, one end of the arc-shaped baffle 1.2.8 is arranged at the material receiving point S, and the other end extends to the material discharging point F. The rotating direction of the rotating drum 1.2.7 is counterclockwise. Exemplarily, the rotating drum 1.2.7 rotates counterclockwise. When the groove 1.2.13 with a width of K3 on the rotating drum 1.2.7 rotates to the material receiving point S, the base rod 1.3.14 (matched with the groove 1.2.13 with a width of K3) falls into the groove 1.2.13 with a width of K3 and rotates counterclockwise with the rotating drum 1.2.7. The groove 1.2.13 is blocked by the arc-shaped baffle 1.2.8 all the way on the path from the material receiving point S to the material discharging point F, thereby preventing the base rod 1.3.14 from falling out of the groove 1.2.13. When the groove 1.2.13 rotates to the material discharging point F, there is no longer the shielding of the arc-shaped baffle 1.2.8, and the base rod 1.3.14 accommodated in the groove 1.2.13 falls into the base rod placing part 1.3.5 of the base rod fixed-length pushing unit 1.3.

[0085] In another embodiment, the arc-shaped baffle 1.2.8 is arranged on the right side of the outer peripheral wall of the rotating drum 1.2.7, one end of the arc-shaped baffle 1.2.8 is arranged at the material receiving point S, and the other end extends to the material discharging point F. The rotating direction of the rotating drum 1.2.7 is clockwise.

[0086] In some other possible embodiments, the arc-shaped baffle 1.2.8 is disposed on the right side of the outer peripheral wall of the rotary drum 1.2.7, and one end of the arc-shaped baffle 1.2.8 is disposed at the midpoint D2, and the other end extends to the discharging point F. The rotation direction of the rotary drum 1.2.7 is clockwise.

[0087] In some other possible embodiments, the arc-shaped baffle 1.2.8 is disposed on the left side of the outer peripheral wall of the rotary drum 1.2.7, and one end of the arc-shaped baffle 1.2.8 is disposed at the midpoint D1, and the other end extends to the discharging point F. The rotation direction of the rotary drum 1.2.7 is counterclockwise.

[0088] With the above technical solution, when any one of the grooves 1.2.13 in the rotary drum 1.2.7 rotates to the position of the arc-shaped baffle 1.2.8, the base rods 1.3.14 in the grooves 1.2.13 are blocked by the arc-shaped baffle 1.2.8, preventing the base rods 1.3.14 from falling at non-discharging points F.

[0089] In some possible embodiments provided by the present invention, the base rod feeding unit 1.2 further includes a plurality of filling blocks (not shown in the figure), and each filling block is used to detachably fill the corresponding groove 1.2.13 and is adapted to the size of the groove 1.2.13.

[0090] In this embodiment, in use, according to the diameter of the base rod 1.3.14 to be target-cut, the groove 1.2.13 with the target width is determined, and the filling block adapted to the groove 1.2.13 with the target width is removed, so that the base rod 1.3.14 to be target-cut is just received by the groove 1.2.13 with the target width, preventing the base rod 1.3.14 from falling into the groove 1.2.13 with a non-target width and causing the problem of stuck rods.

[0091] In some possible embodiments provided by the present invention, the filling block is a magnetic attraction block for magnetically connecting with the groove 1.2.13, making the installation and disassembly simple and fast.

The base bar elastic pressing piece 1.3.9 extends obliquely upward relative to the upper edge of the receiving groove 1.3.15. The included angle α formed by the direction A from the lower edge to the upper edge of the base bar elastic pressing piece 1.3.9 and the pushing direction B of the base bar pushing part is an obtuse angle, and is used to press the base bar 1.3.14 along the vertical direction ( Figure 3 the Z direction shown in

[0111] Referring to Figure 5 , the spring 1.3.12 has a natural length in the natural state P. The base bar elastic pressing piece 1.3.9 is pressed by the spring 1.3.12 and adheres to the base bar placement part 1.3.5. At this time, the base bar 1.3.14 cannot pass through the base bar placement part 1.3.5. Referring to Figure 6, when the base rod scraper 1.3.8 pushes the base rod 1.3.14, the base rod elastic pressing piece 1.3.9 is pushed open, the spring 1.3.12 is compressed, the spring 1.3.12 is in the compressed state S, and the base rod is pushed out of the base rod placement part 1.3.5.

[0112] Reference Figure 1 , the base rod fixed-length pushing unit 1.3 is installed below the base rod blanking unit 1.2, and is used to receive the base rod conveyed by the base rod blanking unit 1.2 and push it to the base rod feeding unit 1.5 after cutting. The base rod 1.3.14 passes through the base rod cutting unit 1.4 and is automatically cut into base rods of the target length.

[0113] Reference Figure 2 , the base rod fixed-length pushing unit 1.3 includes a base rod fixed-length pushing motor 1.3.1, a base rod pushing motor seat 1.3.2, a synchronous pulley 1.3.3, a synchronous belt 1.3.4, a base rod placement part 1.3.5, and a synchronous idler pulley 1.3.6. Reference Figure 3 , the base rod fixed-length pushing unit 1.3 includes a base rod pushing block 1.3.7, a base rod scraper 1.3.8, a base rod elastic pressing piece 1.3.9, a synchronous belt pressing plate 1.3.10, a slider 1.3.11, a spring 1.3.12, an opposed sensor 1.3.13, and a base rod 1.3.14.

[0114] Reference Figure 1 And in combination with Figure 3 And Figure 4 , the base rod 1.3.14 in the base rod blanking unit 1.2 falls into the base rod placement part 1.3.5 of the base rod fixed-length pushing unit 1.3 and is sensed by the opposed sensor 1.3.13. At this time, the base rod pushing motor 1.3.1 drives the synchronous pulley 1.3.3, the synchronous belt 1.3.4, and the synchronous idler pulley 1.3.6 to move, driving the base rod pushing block 1.3.7 and the base rod scraper 1.3.8 to move along the axial direction of the base rod (i.e., the Y direction shown in Figure 3 ) on the slider guide rail, and pushing the base rod 1.3.14 in the base rod placement part 1.3.5 to protrude from the front groove 1.3.15. The base rod 1.3.14 is limited by the base rod elastic pressing piece 1.3.9 and continues to be conveyed forward to prepare for fixed-length cutting. In this embodiment, the synchronous belt pressing plate 1.3.10 presses the synchronous belt 1.3.4 to prevent the synchronous belt 1.3.4 from jumping up and down or shifting left and right, resulting in unstable operation.

Reference Figure 13, the base rod cutting unit 1.4 further includes a cutter bearing inner spacer 1.4.7, a cutter bearing pressing spacer 1.4.8, a base rod cutting lifting cylinder 1.4.9, and a cutter moving slider seat 1.4.10 (as Figure 14 shown). Refer to Figure 8 , the base rod cutting unit 1.4 further includes a base rod positioning bottom plate 1.4.11 and a base rod positioning slider 1.4.12.

[0116] Refer to Figures 8 to 12 , in some possible embodiments provided by the present invention, the base rod cutting unit 1.4 includes a cutting member 1.4.6, and the cutting member 1.4.6 can move between an initial position C and a cutting position J along a cutting direction (such as the Figure 8 shown Z direction) for cutting the base rod 1.3.14 located at the cutting position J.

[0117] As described above, in this embodiment, refer to Figure 3 and Figure 8 , the drum mounting shaft 1.2.10 is fixed on the drum motor substrate 1.2.2, and the inside of the drum mounting shaft 1.2.10 is in the shape of a waist groove. The base rod cutting unit 1.4 will move up and down in the waist groove of the drum mounting shaft 1.2.10 to cut the base rod. Therefore, the drum mounting shaft 1.2.10 is designed in the shape of a waist groove to limit the movement of the base rod cutting unit 1.4.

[0118] Specifically, refer to Figures 8 to 12 and combine with Figure 3 , the cutter bearing sleeve 1.4.2 moves between the vertex W and the bottom point G of the waist groove. Among them, Figures 8 to 10 shows a three-dimensional view of the base rod cutting unit 1.4 when the cutter bearing sleeve 1.4.2 is at the vertex W of the waist groove; Figure 11 shows a three-dimensional view of the base rod cutting unit 1.4 when the cutter bearing sleeve 1.4.2 is at the position between the vertex W and the bottom point G of the waist groove; Figure 12 shows a three-dimensional view of the base rod cutting unit 1.4 when the cutter bearing sleeve 1.4.2 is at the bottom point G of the waist groove.

[0119] Refer to Figures 8 to 10 , when the cutter bearing sleeve 1.4.2 is at the vertex W of the waist groove, the cutting member 1.4.6 is at the initial position C. Refer to Figure 12 , when the cutter bearing sleeve 1.4.2 is at the bottom point G of the waist groove, the cutting member 1.4.6 is at the cutting position J.

[0120] Adopting the above technical solution, the cutting member 1.4.6 moves along the cutting direction (such as the Figure 12 shown Z direction) to cut the base rod 1.3.14 that has been pushed out a certain length at the cutting position J. The movement direction is unique and established, which is beneficial to improving the working efficiency of the cutting member 1.4.6.

[0121] In some possible embodiments provided by the present invention, the cutting member is a blade.

[0122] Reference Figures 8 to 12 and in combination with Figure 7 , in some possible embodiments provided by the present invention, the base rod cutting unit 1.4 includes: a base rod positioning slider 1.4.12, and the base rod positioning slider 1.4.12 can move along the vertical direction (such as Figures 7 to 12 the Z direction shown) between the positioning starting position (such as Figures 8 to 10 the H position shown) and the positioning position (such as Figure 11 the I position shown). In combination with Figures 8 to 11 , the positioning position I is located above the cutting position J along the vertical direction (such as Figures 8 to 11 the Z direction shown).

[0123] Reference Figures 8 to 12 and in combination with Figure 7 , the base rod positioning slider 1.4.12 is provided above the base rod placement portion 1.3.5. Reference Figure 8 , the bottom of the base rod positioning slider 1.4.12 is provided with a positioning groove 1.4.121 for fixing the base rod 1.3.14. When the base rod positioning slider 1.4.12 is at the positioning position (such as Figure 11 the I position shown), the positioning groove 1.4.121 contacts the base rod 1.3.14 to fix the base rod 1.3.14; when the base rod positioning slider 1.4.12 is at a non-positioning position (refer to Figures 8 to 10 the position where the base rod positioning slider 1.4.12 is located in

[0124] Specifically, reference Figures 8 to 10 and in combination with Figure 3 , when the cutter bearing sleeve 1.4.2 is at the vertex W of the waist groove, the cutting member 1.4.6 is at the initial position C, and the base rod positioning slider 1.4.12 is at the positioning starting position H. Reference Figure 11 , when the cutter bearing sleeve 1.4.2 is at a preset intermediate position between the vertex W and the bottom point G of the waist groove, the base rod positioning slider 1.4.12 is at the positioning position I. Reference Figure 12 , when the cutter bearing sleeve 1.4.2 is at the bottom point G of the waist groove, the cutting member 1.4.6 is at the cutting position J. Therefore, as described above, in combination with Figures 8 to 11 , the positioning position I is located above the cutting position J along the vertical direction (such as Figures 8 to 11 the Z direction shown).

[0125] Reference Figure 11, in some possible embodiments provided by the present invention, along the axial direction of the base rod placement part 1.3.5 (the Y direction shown in the figure), the cutting position is located between the base rod positioning slider 1.4.12 and the base rod elastic pressing piece 1.3.9.

[0126] That is, one end (front end) of the base rod 1.3.14 is placed in the base rod placement part 1.3.5 and is pressed tightly by the base rod elastic pressing piece 1.3.9 along the vertical direction (the Y direction shown in the figure), and the other end (rear end) of the base rod 1.3.14 is Figure 3 pushed out of the accommodation groove 1.3.15 by the base rod pushing part 1.3.16 shown in the figure, and the pushed-out part is stuck and positioned by the positioning groove 1.4.121 in the base rod positioning slider 1.4.12. That is, the base rod 1.3.14 has been positioned by the base rod positioning slider 1.4.12 and the base rod elastic pressing piece 1.3.9, and the cutting piece 1.4.6 can achieve stable cutting between these two points, avoiding problems such as the base rod 1.3.14 jumping during cutting or the cutting surface of the base rod 1.3.14 being uneven after cutting due to improper positioning.

[0127] Reference Figure 1 , the base rod cutting unit 1.4 is installed at the central position of the base rod blanking unit 1.2 along the vertical direction (the Z direction shown in the figure), and the cutting piece 1.4.6 of the base rod cutting unit 1.4 is located above the base rod placement part 1.3.5 of the base rod fixed-length pushing unit 1.3 for cutting the base rod.

[0128] In this embodiment, the base rod positioning bottom plate 1.4.11 is connected to the blade pressing cover 1.4.4, the blade pressing cover 1.4.4 is fixed on the cutter bearing sleeve 1.4.2, and the other end of the cutter bearing sleeve 1.4.2 is connected to the cutter moving slider seat 1.4.10.

[0129] When the base rod cutting lifting cylinder 1.4.9 does not extend, at this time, the cutter bearing sleeve 1.4.2 is located at the vertex W of the waist groove, and the base rod positioning slider 1.4.12 is located at the lowest position of the guide rail under the influence of its own weight. In this state, neither the cutting piece 1.4.6 nor the base rod positioning slider 1.4.12 touches the base rod 1.3.14.

[0130] When the base rod in the fixed-length pushing unit 1.3 reaches the position in the base rod placement part 1.3.5, the so-called "reaching the position" here means that the moving distance of the pushing slider in the fixed-length pushing unit 1.3 of the base rod reaches the preset distance, which is regarded as the base rod reaching the position. The base rod cutting motor 1.4.1 operates, drives the cutter rotating shaft 1.4.3 through the coupling, so that the cutting part 1.4.6 rotates rapidly. Then, the base rod cutting lifting cylinder 1.4.9 extends, drives the cutter moving slider seat 1.4.10 to move downward, and makes the base rod positioning bottom plate 1.4.11 move downward. When the cutting part 1.4.6 has not yet contacted the base rod, the base rod positioning slider 1.4.12 descends first under the influence of its own weight, so that the positioning groove 1.4.121 of the base rod positioning slider 1.4.12 catches the base rod 1.3.14. This design is to fix the base rod before cutting the base rod, so that the base rod will not move randomly during cutting. Subsequently, the cutting part 1.4.6 also descends to the position and starts to cut the base rod 1.3.14 to a fixed length.

[0131] Reference Figures 21 to 23 , in some possible embodiments provided by the present invention, the base rod splitting device 1 in the aerosol generating article further includes a base rod feeding unit 1.5 after cutting. The base rod feeding unit 1.5 after cutting includes a base rod adsorbing part 1.5.7, and the base rod adsorbing part 1.5.7 is arranged at the front end of the base rod placement part 1.3.5. Reference Figure 22 , the base rod adsorbing part 1.5.7 is provided with an adsorption groove 1.5.15 for adsorbing the base rod 1.3.14 after cutting.

[0132] Adopting the above technical solution, the base rod adsorbing part 1.5.7 can stably adsorb the base rod 1.3.14 after cutting, prevent the base rod 1.3.14 from falling after splitting, and at the same time, after the base rod adsorbing part 1.5.7 with a negative pressure adsorption function adsorbs the base rod 1.3.14 after cutting, it can also continue the subsequent work process, such as arranging and placing the base rod 1.3.14 after cutting in a predetermined order.

[0133] Reference Figures 21 to 23 , in some possible embodiments provided by the present invention, the base rod feeding unit 1.5 after cutting includes a base rod picking and placing rotating shaft 1.5.6, which is connected to the base rod adsorbing part 1.5.7 and can drive the base rod adsorbing part 1.5.7 to flip 180 degrees. The base rod picking and placing rotating shaft 1.5.6 can move from the base rod adsorption position to the base rod placement position along the vertical direction ( Figures 21 to 23 the Z direction shown in

[0134] Reference Figure 21 and Figure 22 , in some possible embodiments provided by the present invention, the base rod feeding unit 1.5 after cutting includes a base rod pushing slider 1.5.4, and the base rod pushing slider 1.5.4 can drive the base rod picking and placing rotating shaft 1.5.6 along the vertical direction (such asFigure 21 and Figure 22 The (Z direction shown) moves between the initial position and the placement position of the base rod of the slider 1.5.4 pushed by the base rod.

[0135] With the above technical solution, the base rod adsorbing member 1.5.7 stably adsorbs the cut base rod 1.3.14, the base rod picking and placing rotating shaft 1.5.6 drives the base rod adsorbing member 1.5.7 to flip 180 degrees, and the base rod pushing slider 1.5.4 drives the base rod picking and placing rotating shaft 1.5.6, thereby driving the base rod adsorbing member 1.5.7 to move in the vertical direction, so as to arrange and place the cut base rod 1.3.14 at the base rod placement position in a predetermined order.

[0136] Reference Figure 21 , the base rod post-cutting feeding unit 1.5 is installed below the base rod fixed-length pushing mechanism 1.3, and the rear end is connected to a large-flow high-pressure centrifugal fan outside the base rod post-cutting feeding unit 1.5 by an air duct 1.5.101, which is used to receive the base rod conveyed by the base rod fixed-length pushing unit 1.3 and cooperate with the base rod cutting unit 1.4 to cut the base rod. After cutting, it cooperates with the base slide 1.6 to convey the base rod to the next unit to complete the sorting and combination of each cut base rod.

[0137] Reference Figure 21 , the base rod post-cutting feeding unit 1.5 includes a base rod feeding motor 1.5.1, an eccentric wheel 1.5.2, a rocker arm 1.5.3, a base rod pushing slider 1.5.4, a base rod picking and placing bearing seat 1.5.5, a base rod picking and placing rotating shaft 1.5.6, and a base rod segmented adsorption block 1.5.7. Reference Figure 23 And in combination with Figure 22 , the base rod post-cutting feeding unit 1.5 includes a base rod picking and placing bearing spacer 1.5.8, a base rod picking and placing bearing gland 1.5.9, a rocker arm air duct 1.5.101 connecting sleeve 1.5.10, a base rod picking and placing guide arm 1.5.11, a swing arm positioning shaft 1.5.12, a swing arm lower positioning block 1.5.13, and a swing arm upper positioning block 1.5.14.

[0138] In some possible embodiments, the base rod picking and placing rotating shaft 1.5.6 can also drive the base rod segmented adsorption block 1.5.7 to displace in the left-right direction (such as the X direction shown in Figure 1 ) relative to the placed base rod. Because the length of the cut base rod may not be precise, if it is directly placed, it is easy to knock over the already placed base rod. Therefore, it displaces in the left-right direction (such as the X direction shown in Figure 1 ) to adjust the deviation of the placement position.

[0139] The high-flow high-pressure centrifugal fan generates negative pressure through the air duct 1.5.101 and the air channel 1.5.102, enabling the base rod suction attachment 1.5.7 to adsorb the cut base rod. After the base rod feeding motor 1.5.1 operates, the eccentric wheel 1.5.2 drives the rocker arm 1.5.3 to perform eccentric motion, causing the base rod picking and placing rotating shaft 1.5.6 to move downward along the slider guide rail 1.5.18. At this time, the gear 1.5.19 installed on the base rod picking and placing rotating shaft 1.5.6 meshes with the rack, causing the base rod picking and placing rotating shaft 1.5.6 to rotate 180 degrees, making the cut base rod face downward, ready to be placed into the next unit (the composite base rod annular belt combination unit), and subsequently completing the sorting and combination of all cut base rods.
