Description

Technical Field

[0001] At least one embodiment of this application relates to the field of tobacco manufacturing equipment, and more specifically, to a base rod cutting device. Background Technology

[0002] In the manufacturing process of tobacco products, the base rods need to be cut into certain lengths according to requirements before being sent to the next station for further processing. In related technologies, the base rod feeding mechanism used in the base rod cutting process is a negative pressure suction cup. The negative pressure suction cup extends into the chamber containing the base rods and sucks them up with negative pressure. However, because the surface of the base rod is curved, it is difficult to suck up the base rod when the negative pressure is small, and when the negative pressure is large, it can easily cause the base rod to deform and affect subsequent processing. Summary of the Invention

[0003] To address at least one of the above-mentioned and other technical problems in the prior art, embodiments of this application provide a base rod cutting device that helps to stably feed the base rod during the cutting process, ensuring feeding reliability and the subsequent processing quality of the base rod.

[0004] According to an embodiment of this application, a base bar cutting device includes a base, a material conveying assembly, a hopper, a cutting assembly, and a lifting mechanism. The material conveying assembly includes a loading platform and a pushing device. The loading platform is mounted on the base and has a chute. The chute has a first end and a second end opposite to each other. The pushing device is configured to reciprocate along the chute. The hopper is configured to receive base bars and is located on one side of the chute. The cutting assembly is located at the second end and is configured to cut the base bars. The lifting mechanism is configured to move vertically through the bottom of the hopper to push a base bar out of the hopper and into the chute, where it is then pushed to the second end by the pushing device.

[0005] According to an embodiment of this application, the feeding device includes a slide rail, a slider, and a feeding assembly. The slide rail is mounted on a base and extends along the length of the groove. The slider is configured to slide on the slide rail. The feeding assembly is mounted on the slider and is configured to extend into the groove from above to push the base rod as the slider moves.

[0006] According to an embodiment of this application, the pusher assembly includes a pusher rod and a pusher member. The pusher rod is mounted on the slider and extends vertically. The pusher member is mounted on the pusher rod and is configured in an L-shape, with one sidewall extending along the width direction of the groove to the top of the groove, and the other sidewall extending vertically downward to extend into the groove to push the base rod as the slider moves.

[0007] According to an embodiment of this application, the hopper includes a bottom plate and four side plates, and the lifting mechanism includes a lifting plate and a first driving member. The lifting plate passes through the bottom plate of the hopper on the inner side of the output side plate of the conveying assembly, which is closer to the four side plates. The first driving member is disposed on a base and is configured to drive the lifting plate to move up and down. The bottom plate is inclined downward toward the chute to guide the base bar to slide onto the lifting plate.

[0008] According to an embodiment of this application, a guide plate is provided between the output side plate and the chute, and a discharge port is provided through the output side plate. The lifting mechanism also includes a second driving member. The second driving member is disposed on the base and is configured to drive the output side plate to reciprocate linearly in the vertical direction between a first height where the upper edge of the output side plate is flush with the upper edges of other side plates and a second height where the discharge port is flush with the upper edge of the guide plate.

[0009] According to an embodiment of this application, the upper edge of the lifting plate is inclined downward toward the output side plate, such that when the output side plate is at a first height, the lifting plate is driven upward by the first driving member so that a base rod falls into the discharge port and is blocked by the side wall of the guide plate.

[0010] According to an embodiment of this application, the upper edge of the guide plate is inclined downward toward the chute, so that when the output side plate rises to the second height, the base rod rolls out through the discharge port and slides down along the upper edge of the guide plate into the chute.

[0011] According to an embodiment of this application, the base bar cutting device further includes a space adjustment component. The space adjustment component includes a movable plate, a slide table, and a third driving component. The movable plate is located inside the hopper and is perpendicular to the length direction of the chute. The slide table passes through the hopper and connects to the movable plate. The third driving component, disposed on a base, is configured to drive the movable plate to reciprocate linearly along the length direction of the chute by driving the slide table, thereby changing the hopper's capacity length.

[0012] According to an embodiment of this application, the cutting assembly includes a clamping device and a cutting device. The clamping device includes a clamping plate and a fourth driving member. The clamping plate is disposed in a horizontal direction, and the fourth driving member is configured to drive the clamping plate to reciprocate linearly along the width direction of the slide groove, switching between two states: pressing against the base rod and disengaging from the base rod. The cutting device is mounted on a base and configured to cut the base rod when the clamping plate presses against the base rod in the slide groove.

[0013] According to an embodiment of this application, the cutting device includes a blade body, a motor, and a fifth driving member. The output end of the motor is fixed to the blade body. The fifth driving member is equipped with a carrier, the motor is fixed on the carrier, and the fifth driving member is mounted on a crossbeam above the base. It is configured to drive the carrier to reciprocate linearly in the vertical direction, thereby causing the blade body to switch between two states: cutting the base bar and detaching from the base bar.

[0014] According to the embodiment of this application, the base rod cutting device uses a lifting mechanism that moves up and down through the bottom of the hopper to push the base rods in the hopper into the chute. This mechanical ejection feeding method improves the success rate of feeding the base rods during the cutting process, prevents deformation of the base rods, and outputs a single base rod per feeding, ensuring feeding reliability and the subsequent processing quality of the base rods. A pushing device pushes the base rods that fall into the chute from the first end and moves along the chute to the second end to transport the base rods to the cutting assembly, achieving continuous and stable execution of base rod feeding, conveying, and cutting, thus improving operational stability.

[0030] It should also be noted that the directional terms mentioned in the embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are only references to the directions in the accompanying drawings and are not used to limit the protection scope of the present application.

When it may cause confusion in the understanding of the present application, the conventional structures or configurations will be omitted.

[0031] In the industrial manufacturing process of tobacco products, the base rod is the basic rod material for processes such as cigarette filter assembly and preparation of heated non-combustible cigarettes. The base rod has a cylindrical structure and includes various types such as acetate fiber filter rods, hollow structure filter rods, bead composite base rods, and paper-based support rods. In the standardized production process of tobacco products, the whole base rod needs to be cut into small segments of a preset length according to the design specifications of the finished cigarette sticks, and then transported to the next station to complete subsequent processes such as compounding, assembly, and rolling.

[0032] In the related art, the automated feeding mechanism for the base rod cutting process mostly adopts a negative pressure suction cup feeding scheme. This scheme provides negative pressure adsorption force for the negative pressure suction cup through a vacuum system, controls the negative pressure suction cup to extend into the storage bin containing the base rod, grabs a single base rod through negative pressure adsorption, and then transfers it into the conveying channel of the cutting equipment, so as to achieve the automated feeding of the base rod. However, since the base rod has a cylindrical structure and the outer surface is a continuous arc, when the set negative pressure value of the system is small, the adsorption force is not sufficient to stably grab the base rod, and problems such as material dropping and missed suction are likely to occur; when the negative pressure value is increased, the base rod will be deformed due to the local high-pressure negative pressure effect, affecting the quality and consistency of the subsequent processed products.

[0033] Figure 1 A perspective three-dimensional schematic diagram of a base rod cutting device according to an embodiment of the present application is schematically shown.

[0034] As Figure 1 shown, the present application provides a base rod cutting device, which includes a base 1, a material transporting component 2, a material bin 3, a cutting component ⑤, and a lifting mechanism 6. The material transporting component 2 includes a material loading platform 21 and a pushing device 22. The material loading platform 21 is installed on the base 1 and is provided with a sliding groove 211. The sliding groove 211 has opposite first and second ends. The pushing device 22 is configured to reciprocate along the sliding groove 211. The material bin 3 is configured to accommodate the base rod 4 and is located on one side of the sliding groove 211. The cutting component ⑤ is arranged at the second end and is configured to cut the base rod 4. The lifting mechanism 6 is configured to move up and down through the bottom of the material bin 3 to push a base rod 4 in the material bin 3 out of the material bin 3 and onto the sliding groove 211, and then be pushed to the second end by the pushing device 22.

[0035] In some exemplary embodiments, the base 1 is placed horizontally, and the material conveying assembly 2 is mounted on top of the base 1. The material platform 21 is a long strip structure that extends horizontally and is fixed above the base 1. The material platform 21 is connected to the base 1, for example, by welding or bolting multiple upright support columns. The chute 211 is formed by a downward recess from the top surface of the material platform 21 and extends along the length of the material platform 21 to penetrate the top of the material platform 21. The width and depth of the chute 211 are both greater than the diameter of a base rod 4. The chute 211 forms opposing first and second ends along its own length.

[0036] In some exemplary embodiments, a pushing device 22 is mounted on one side of the loading platform 21, and the pushing device 22 is configured to reciprocate linearly between a first end and a second end along the length direction of the chute 211. A hopper 3 is fixedly mounted above the base 1, located on the other side of the loading platform 21 away from the pushing device 22, and its position is aligned with the first end of the chute 211. A cutting assembly 5 is fixed above the base 1, located on the other side of the loading platform 21 away from the pushing device 22, i.e., the cutting assembly 5 and the hopper 3 are arranged on the same side of the loading platform 21, and its position is aligned with the second end of the chute 211.

[0037] In some exemplary embodiments, the base 1 has a through slot that allows the lifting mechanism 6 to pass through. The lifting mechanism 6 is installed at the bottom of the base 1, and its movable component passes upward through the base 1 and the bottom of the hopper 3. By moving the movable component of the lifting mechanism 6 from bottom to top, a base rod 4 in the hopper 3 is pushed out of the hopper 3 and falls into the chute 211. Then, it is pushed to the second end by the pushing device 22, so that the base rod 4 reaches the distribution position of the cutting assembly 5.

[0038] According to the embodiment of this application, the base rod cutting device uses a lifting mechanism 6 that moves up and down through the bottom of the hopper 3 to push the base rod 4 in the hopper 3 into the chute 211. This mechanical ejection feeding method improves the success rate of feeding the base rod 4 during the cutting process. The base rod 4 will not deform, and each feeding outputs a single base rod 4, ensuring feeding reliability and the subsequent processing quality of the base rod 4. The pushing device 22 pushes the base rod 4 into the chute 211 from the first end and moves along the chute 211 to the second end to transport the base rod 4 to the cutting assembly 5. This achieves continuous and stable execution of base rod feeding, conveying, and cutting, improving operational stability.

[0039] Figure 2 Schematic illustration Figure 1 An enlarged schematic diagram of part A in the middle.

[0040] like Figure 2As shown, according to an embodiment of this application, the feeding device 22 includes a slide rail 221, a slider 222, and a feeding assembly. The slide rail 221 is mounted on the base 1 and extends along the length of the groove 211. The slider 222 is configured to slide on the slide rail 221. The feeding assembly is mounted on the slider 222 and is configured to extend into the groove 211 from above to push the base rod 4 as the slider 222 moves. The feeding assembly includes a feeding rod 223 and a pushing member 224. The feeding rod 223 is mounted on the slider 222 and extends vertically. The pushing member 224 is mounted on the feeding rod 223 and is configured in an L-shape, with one sidewall extending along the width of the groove 211 to the top of the groove 211, and the other sidewall extending vertically downward to extend into the groove 211 to push the base rod 4 as the slider 222 moves.

[0041] In some exemplary embodiments, the slide rail 221 is fastened to the upper surface of the base 1 by bolts or welding. The top surface height of the slide rail 221 is, for example, lower than the bottom surface height of the loading platform 21. The slide rail 221 extends along the length direction of the slide groove 211 and is arranged parallel to and spaced apart from the loading platform 21. The slider 222 is a combined structure formed by bolting together multiple plates, including a main plate, a mounting plate, a clamping plate, a sensing plate, and a photoelectric sensor. The slider 222 is placed on the upper surface of the slide rail 221 and can reciprocate linearly along the length direction of the slide rail 221 under the drive of, for example, a drive motor.

[0042] In some exemplary embodiments, both the main body plate and the mounting plate are horizontally extending plates. The main body plate is placed against the upper surface of the slide rail 221, and the mounting plates are arranged parallel to each other directly above the main body plate. Four clamping pieces are arranged at the four corners between the mounting plate and the main body plate. Bolts pass through the mounting plate, clamping pieces, and main body plate from top to bottom and are then tightened, thereby splicing the mounting plate, clamping pieces, and main body plate into the load-bearing frame of the slider 222. The spacing between the mounting plate and the main body plate can be adjusted by replacing the clamping pieces, and the clamping pieces also help to improve the overall structural rigidity of the slider 222.

[0043] In some exemplary embodiments, the outer wall of the slide rail 221 away from the loading platform 21 is also provided with a sensor mounting groove extending along the length direction of the slide rail 221. Two photoelectric sensors, namely an origin sensor and an extreme position sensor, are fixedly installed at intervals along the length direction of the slide rail 221. Both photoelectric sensors are fixedly installed in the sensor mounting groove by connecting plates. The installation position of the origin sensor corresponds to the origin reset position of the reciprocating motion of the slider 222 (e.g., aligned with the first end), and the installation position of the extreme position sensor corresponds to the maximum thrust limit position of the reciprocating motion of the slider 222 (e.g., aligned with the second end). A sensing plate is fixedly fastened to the side of the main plate of the slider 222 facing the sensor mounting groove by bolts. The sensing plate reciprocates linearly along the length direction of the slide rail 221 synchronously with the slider 222.

[0044] Furthermore, during device operation, the origin sensor is used to calibrate the reset origin of slider 222. Each time the device is started or after a single feeding action is completed, slider 222 moves along slide rail 221 towards the origin. When the sensing element extends into the sensing slot of the origin sensor, the origin sensor is triggered and sends an origin arrival signal. The control system then controls slider 222 to stop moving and completes the reset, thus ensuring that the starting position of each feeding action is completely consistent. The limit position sensor is used to limit the maximum forward stroke of slider 222. When slider 222 moves the sensing element to the limit position sensor and the sensing element extends into the sensing slot to trigger the sensor, the control system immediately controls slider 222 to stop moving forward, avoiding collisions caused by overtravel of slider 222.

[0045] According to the above embodiments of this application, the slider 222 and the pusher 224 are connected by a vertically arranged pusher rod 223, so that the pusher 224 can extend into the slide groove 211 from above, avoiding interference with the loading platform 21. The L-shaped pusher 224 structure can achieve a stable connection with the pusher rod 223 through the horizontally extending sidewall, and can also form contact with the end face of the base rod 4 through the vertically extending sidewall. Furthermore, the cooperation between the slide rail 221 and the slider 222 provides linear motion guidance for the pusher assembly, preventing the base rod 4 from deflecting or jamming, and ensuring the smoothness and positioning accuracy of the base rod 4.

Figure 6 Schematic illustration Figure 3 A three-dimensional schematic diagram of the base rod cutting device from another perspective.

[0047] like Figures 3-6As shown in the embodiment of this application, the hopper 3 includes a bottom plate 31 and four side plates, and the lifting mechanism 6 includes a lifting plate 61 and a first driving member 62. The lifting plate 61 passes through the bottom plate 31 of the hopper 3 on the inner side of the output side plate 32 of the conveying component 2. The first driving member 62 is disposed on the base 1 and is configured to drive the lifting plate 61 to move up and down. The bottom plate 31 is inclined downward toward the slide 211 to guide the base rod 4 to slide onto the lifting plate 61. A guide plate 7 is disposed between the output side plate 32 and the slide 211, and a discharge port 33 is provided through the output side plate 32. The lifting mechanism 6 also includes a second driving member 63. The second driving member 63 is disposed on the base 1 and is configured to drive the output side plate 32 to reciprocate linearly in the vertical direction between a first height where the upper edge of the output side plate 32 is flush with the upper edges of the other side plates and a second height where the discharge port 33 is flush with the upper edge of the guide plate 7. The upper edge of the lifting plate 61 is inclined downward toward the output side plate 32, so that when the output side plate 32 is at the first height, the lifting plate 61 is driven to rise by the first driving member 62 so that a base rod 4 falls into the discharge port 33 and is blocked by the side wall of the guide plate 7.

[0048] In some exemplary embodiments, the bottom plate 31 of the hopper 3 and four side plates together form a rectangular receiving cavity with a top opening. The four side plates are an output side plate 32 near the conveying assembly 2, a third side plate 35 opposite to the output side plate 32, and a second side plate 34 and a fourth side plate 36 respectively connecting the two ends of the output side plate 32 and the third side plate 35. The output side plate 32 is perpendicular to the width direction of the chute 211. The second side plate 34 and the fourth side plate 36 both extend to the upper surface of the base 1 and are fixed by bolts or welding. The top surface of the bottom plate 31 forms a slope that slopes downward toward the output side plate 32, causing the base rod 4 inside the hopper 3 to automatically roll toward the output side plate 32 under gravity. The slope angle is, for example, 15°-35°, such as 30°. The lifting plate 61 is located on the inner side of the output side plate 32 away from the material conveying component 2. The bottom plate 31 has a through groove that matches the cross section of the lifting plate 61. The lifting plate 61 passes through this through groove. The bottom end of the lifting plate 61 is fixedly connected to the movable part of the first driving member 62, such as a cylinder.

[0049] In some exemplary embodiments, the output side plate 32 is parallel to the length direction of the chute 211, and the discharge port 33 extends through the thickness direction of the output side plate 32. The height of the discharge port 33 is greater than the diameter of one base rod 4, and the width of the discharge port 33 is greater than the length of one base rod 4. The guide plate 7 is fixed between the output side plate 32 and the loading platform 21, and the guide plate 7 is parallel to the output side plate 32. The bottom end of the output side plate 32 is fixedly connected to the movable part of the second driving member 63, such as a cylinder. The upper edge width of the lifting plate 61 is greater than the diameter of one base rod 4 and less than the diameter of two base rods 4. The upper edge of the lifting plate 61 is an inclined surface that slopes downward toward the output side plate 32, and the inclination angle of the inclined surface is, for example, the same as the inclination angle of the top surface of the bottom plate 31, such as 30°.

[0050] According to the above embodiments of this application, the base rod 4 in the hopper 3 can automatically roll to the upper edge of the lifting plate 61 under the action of gravity through the inclined base plate 31. Since the upper edge width of the lifting plate 61 limits the number of base rods 4 to one, a base rod 4 falls to the upper edge of the lifting plate 61 and is blocked by the side wall of the output side plate 32. With the upward lifting action of the first driving member 62, the conveying of a single base rod 4 can be realized. Furthermore, when the upper edge of the lifting plate 61 is flush with the discharge port 33, since the upper edge of the lifting plate 61 is inclined downward toward the output side plate 32, a base rod 4 can automatically roll into the discharge port 33 under the action of gravity. With the second driving member 63, the output side plate 32 is lifted upward to a second height so that the discharge port 33 is flush with the upper edge of the guide plate 7. The guide plate 7 no longer blocks the discharge port 33, so that the base rod 4 can fall out of the discharge port 33. Therefore, the method of discharging the base rod 4 from the hopper 3 by the cooperation of the base plate 31, the lifting plate 61, the output side plate 32 and the guide plate 7 is simple and reliable, and can ensure the accuracy of single rod feeding to avoid problems such as material jamming caused by the simultaneous discharge of multiple base rods 4.

[0051] According to the embodiment of this application, the upper edge of the guide plate 7 is inclined downward toward the slide groove 211, so that when the output side plate 32 rises to the second height, the base rod 4 rolls out through the discharge port 33 and slides down along the upper edge of the guide plate 7 into the slide groove 211.

[0052] In some exemplary embodiments, the upper edge of the guide plate 7 extends parallel to the length direction of the chute 211, and the extension length of the upper edge of the guide plate 7 is greater than the length of a base rod 4. The upper edge of the guide plate 7 is a downward inclined surface facing the chute 211, with an inclination angle of, for example, 35°-60°, such as 45°. The width of the upper edge of the guide plate 7 is greater than the diameter of a base rod 4, and the lowest point of the upper edge of the guide plate 7 is flush with the top surface of the chute 211. The sidewall of the guide plate 7 facing the output side plate 32 is a vertical plane, which can laterally limit the base rod 4 in the discharge port 33 when the output side plate 32 is at a first height.

[0053] According to the above embodiments of this application, when the output side plate 32 rises to the second height via the upper edge of the inclined guide plate 7, the base rod 4 in the discharge port 33 can automatically roll down along the upper edge of the guide plate 7 into the chute 211 under the action of gravity, without the need for an additional pushing structure, so as to achieve a smooth transition of the base rod 4 from the hopper 3 to the chute 211, avoid the base rod 4 from bouncing or deviating during the dropping process, and ensure that the base rod 4 falls accurately into the chute 211, providing a stable foundation for subsequent pushing and conveying actions.

[0054] According to an embodiment of this application, the base rod cutting device further includes a space adjustment component 8. The space adjustment component 8 includes a movable plate 81, a slide table 82, and a third driving component 83. The movable plate 81 is located inside the hopper 3 and is perpendicular to the length direction of the chute 211. The slide table 82 passes through the hopper 3 and connects to the movable plate 81. The third driving component 83 is disposed on the base 1 and is configured to drive the movable plate 81 to reciprocate linearly along the length direction of the chute 211 by driving the slide table 82, thereby changing the accommodating length of the hopper 3.

[0055] In some exemplary embodiments, the movable plate 81 is, for example, a vertically arranged rectangular plate structure located in the receiving cavity of the hopper 3. The movable plate 81 is perpendicular to the length direction of the chute 211, and the bottom edge of the movable plate 81 is in contact with the top surface of the bottom plate 31. The two sides of the movable plate 81 are in contact with the inner wall surface of the lifting plate 61 and the inner wall surface of the third side plate 35 which is opposite to the output side plate 32, respectively. The upper edge of the movable plate 81 is flush with the upper edges of the output side plate 32 and other side plates when it is at the first height.

[0056] In some exemplary embodiments, one of the second side plate 34 and the fourth side plate 36 connecting the output side plate 32 and the third side plate 35 has a through hole to allow the slide 82 to pass through the hopper 3 and connect to the moving plate 81. For example, the second side plate 34 has a through hole with an opening area larger than the slide 82 and smaller than the moving plate 81. The slide 82 is arranged in a horizontal direction, with one end passing through the through hole and fixedly connected to the moving plate 81, and the other end fixedly connected to the output shaft of the third drive member 83. The third drive member 83 is fixed above the base 1, and the extension direction of the output shaft of the third drive member 83 is parallel to the length direction of the slide groove 211. The third drive member 83 is, for example, a cylinder.

[0057] According to the above embodiments of this application, the third driving member 83 drives the slide table 82 to move the moving plate 81 along the length direction of the slide groove 211. The accommodating length of the hopper 3 can be flexibly adjusted so that the hopper 3 can accommodate base rods 4 of different lengths, thereby improving the applicability of the base rod cutting device. Through the close fit between the moving plate 81 and the side plate and bottom plate 31 of the hopper 3, the sealing of the hopper 3 is ensured while adjusting the accommodating length, preventing the base rods 4 from falling out of the gaps and ensuring the reliability of the base rod cutting device.

[0059] like Figure 7 As shown, multiple base rod cutting devices are arranged relatively parallel to each other on the ground, and the base 1 of each base rod cutting device is installed on the upper surface of the working platform 9.

[0060] Figure 8 Schematic illustration Figure 7 Enlarged diagram of part B.

[0061] like Figures 1-8 As shown in the embodiment of this application, for each base rod cutting device: the cutting assembly 5 includes a clamping device 51 and a cutting device 52. The clamping device 51 includes a clamping plate 511 and a fourth driving member 512. The clamping plate 511 is disposed in the horizontal direction, and the fourth driving member 512 is configured to drive the clamping plate 511 to reciprocate linearly along the width direction of the slide groove 211 to switch between two states: pressing against the base rod 4 and disengaging from the base rod 4. The cutting device 52 is mounted on the base 1 and is configured to cut the base rod 4 when the clamping plate 511 presses against the base rod 4 on the slide groove 211. The cutting device 52 includes a blade body 521, a motor 522, and a fifth driving member 523. The output end of the motor 522 is fixed to the blade body 521. The fifth drive unit 523 is equipped with a carrier 524, and the motor 522 is fixed on the carrier 524. The fifth drive unit 523 is mounted on the crossbeam 100 above the base 1 and is configured to drive the carrier 524 to reciprocate linearly in the vertical direction, so as to drive the cutter body 521 to switch between two states: cutting the base rod 4 and being detached from the base rod 4.

[0062] In some exemplary embodiments, the clamping plate 511 is, for example, a horizontally arranged rectangular plate structure, located on the side of the loading platform 21 away from the pushing device 22, and arranged on the same side of the loading platform 21 as the hopper 3. The distribution position of the clamping plate 511 is aligned with the second end position of the slide 211. The height of the upper edge of the side wall of the loading platform 21 near the clamping plate 511 is lower than the bottom surface height of the clamping plate 511, so that the clamping plate 511 can cross one side of the loading platform 21 and face the slide 211. The fourth driving member 512 is fixed to the base 1, and the output shaft of the fourth driving member 512 is fixedly connected to the clamping plate 511. The fourth driving member 512 drives the clamping plate 511 to move along the width direction of the slide 211. The fourth driving member 512 is, for example, a motor 522.

[0063] Specifically, when a base rod 4 is discharged from the hopper 3 and falls into the chute 211, the pushing device 22 moves along the chute 211 to transport the base rod 4 to the second end. At this time, the fourth driving member 512 drives the clamping plate 511 to move toward the chute 211 so that the side wall of the clamping plate 511 presses against the base rod 4 in the chute 211. The side wall of the clamping plate 511 and the side wall of the opposite loading platform 21 cooperate to clamp the base rod 4 together.

[0064] In some exemplary embodiments, a horizontally arranged crossbeam 100 is fixed above the base 1. A fifth drive member 523 is mounted on the crossbeam 100. The fifth drive member 523 is, for example, a cylinder. The output shaft of the fifth drive member 523 is fixedly connected to the carrier 524. The carrier 524 is, for example, an L-shaped mounting plate. One sidewall extends horizontally to connect the fifth drive member 523, and the other sidewall extends vertically downward to mount a motor 522. The motor 522 is fastened to the carrier 524, for example, by bolts. The blade body 521 includes a cutting blade and a protective housing. The cutting blade is circular and configured to rotate about a central axis. The output shaft of the motor 522 extends along the length of the groove 211 and is coaxially fixedly connected to the central axis of the cutting blade. The protective housing covers the cutting blade and is fixedly mounted to the carrier 524 or the motor 522. The protective housing is spaced apart from the cutting blade to ensure that the rotation of the cutting blade driven by the motor 522 is not interfered with. The bottom of the protective housing is also provided with an avoidance opening to ensure that the contact between the cutting blade and the base rod 4 in the slide groove 211 is not obstructed.

[0065] Furthermore, the clamping plate 511 extends to one side of the cutting blade and is spaced apart from the cutting blade, and a cutting slit is provided at the position where the loading platform 21 is aligned with the cutting blade so that the cutting blade can cut through the base rod 4 and extend into it, thereby avoiding rigid collision between the cutting blade and the loading platform 21 and ensuring effective contact between the cutting blade and the base rod 4 in the groove 211.

[0066] According to the above embodiments of this application, on the one hand, when the clamping plate 511 is in a position far away from the slide 211, one side of the slide 211 is open to facilitate the operator to perform operations such as replenishing the base rod 4 in case of malfunctions such as jamming or deformation of the base rod 4; on the other hand, through the cooperation of the clamping plate 511 of the clamping device 51 and the fourth driving member 512, the base rod 4 can be clamped and fixed after being delivered to the position, preventing displacement or rotation of the base rod 4 during the cutting process and ensuring cutting accuracy. The fifth driving member 523 drives the carrier 524 to move downward and drives the blade 521 to contact the base rod 4. At the same time, the motor 522 drives the blade 521 to cut the base rod 4, so that the base rod 4 is cut to the required length. After the cutting is completed, the fifth driving member 523 drives the carrier 524 to move upward and drives the blade 521 to lift and disengage from the base rod 4, avoiding interference with the subsequent delivery of the base rod 4. In addition, the carrier 524 enables a stable connection between the motor 522 and the fifth drive component 523, ensuring the operational stability of the cutter body 521 during the cutting process and improving the flatness and processing quality of the cut surface.

[0067] In some exemplary embodiments, please refer to Figure 8 As shown, multiple base bar cutting device slides 211 are arranged parallel to each other on the working platform 9. The first ends of the slides 211 are aligned with each other, and the second ends of the slides 211 are also aligned with each other. A crossbeam 100 extends above the slides 211 perpendicular to their extending direction. Both ends of the crossbeam 100 are connected to two vertically arranged support frames 101, which are symmetrically mounted on both sides of the working platform 9. Fifth drive members 523 of the multiple base bar cutting devices are spaced apart on one side of the crossbeam 100, with each fifth drive member 523 located above its corresponding second end.

[0068] For each base bar cutting device: After multiple base bars 4 are placed into the hopper 3, the lifting mechanism 6 is activated to push one base bar 4 out of the hopper 3 and into the chute 211. Then, the pushing device 22 is activated to push the base bar 4 to the second end, and the cutting assembly 5 is activated to cut the base bar 4 so that the length of the base bar 4 at the second end reaches the target value.

[0069] A robotic arm 10 is movably mounted on a work platform 9. Multiple suction heads 102 are provided at the end of the robotic arm 10. Each suction head 102 is configured to pick up a base rod 4 located at its second end and hold the base rod 4 on the suction head 102. The number of suction heads 102 matches the number of base rod cutting devices, so that the robotic arm 10 can sequentially pick up base rods 4 located at multiple second ends, simultaneously holding multiple base rods 4 on the suction head 102. The robotic arm 10 transports multiple base rods 4 to the subsequent tobacco rod forming device, saving time in feeding the tobacco rod forming process and improving the production continuity of the entire tobacco rod production process.
