[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0064] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0065] Please refer to Figure 1 andFigure 2 , Figure 1 The schematic view of the disc paper guiding device provided by the embodiment of the present application, Figure 2 The schematic view of the first adjusting assembly and the second adjusting assembly provided by the embodiment of the present application.

[0066] In the first specific embodiment, the disc paper guiding device provided by the embodiment of the present application mainly comprises a disc paper contact rod 1, a clamping rod 2, a first adjusting assembly 3 and a limiting seat 4. The clamping rod 2 can move relative to the disc paper contact rod 1, and the moving direction includes a first direction close to the disc paper contact rod 1 and a second direction away from the disc paper contact rod 1. The first adjusting assembly 3 is arranged on the clamping rod 2, and the first adjusting assembly 3 is used to drive the clamping rod 2 to clamp the disc paper (the paper tape wound on the disc paper) together with the disc paper contact rod 1. The first adjusting assembly 3 comprises a first torsional spring 301 and a first adjusting part 302. The first torsional spring 301 is used to drive the clamping rod 2 to move in the first direction, and the first end of the first torsional spring 301 is connected with the limiting seat 4. The first adjusting part 302 is connected with the second end of the first torsional spring 301, and the torsion of the first torsional spring 301 can be adjusted by rotating the first adjusting part 302.

[0067] Due to the fragility of the disc paper itself and the significant differences in the thickness, width, material and paper tape tension of different disc papers, the disc paper (paper tape) is easily damaged by excessive clamping force or falls off due to insufficient clamping force. It is difficult to meet the demand for efficient and accurate paper guiding in modern tobacco production.

[0068] In view of the above problems, the present application provides a disc paper guiding device, which solves the problems of disc paper damage or falling off caused by improper clamping force in the traditional paper guiding device through ingenious mechanical design. The device mainly comprises a disc paper contact rod 1, a clamping rod 2, a first adjusting assembly 3 and a limiting seat 4. The clamping rod 2 can move relative to the disc paper contact rod 1, and the moving direction includes a first direction close to the disc paper contact rod 1 and a second direction away from the disc paper contact rod 1. The design of relative movement enables the clamping rod 2 to flexibly adjust the clamping position according to the characteristics of different disc papers, thereby providing a basis for accurate control of the clamping force.

[0069] The first adjusting assembly 3 is arranged on the clamping rod 2, and the core components thereof include the first torsional spring 301 and the first adjusting part 302. The first torsional spring 301 is used to drive the clamping rod 2 to move in the first direction, i.e. to move close to the disc paper contact rod 1, thereby realizing the clamping action. The first end of the first torsional spring 301 is connected with the limiting seat 4, and the limiting seat 4 serves to provide a stable support point for the torsional spring, thereby ensuring that the torsional spring can maintain stable elastic force output during the working process. The first adjusting part 302 is connected with the second end of the first torsional spring 301, and the torsion of the first torsional spring 301 can be adjusted by rotating the first adjusting part 302. This design enables the operator to flexibly adjust the size of the clamping force according to the actual demand, thereby adapting to the strict requirements of different disc papers on the clamping force.

[0070] In combination with the above structure and process, it can be seen that the disc paper guiding device has at least the following beneficial effects: the disc paper guiding device solves the problem of disc paper damage or falling caused by improper clamping force, and significantly improves the adaptability and reliability of the disc paper guiding device to different disc papers.

[0071] For reference Figures 3 to 5 Among them, Figure 3 a schematic diagram of a paper disc contact rod and a clamping rod provided by an embodiment of the present application, Figure 4 a schematic diagram of a first torsional spring and a second torsional spring provided by an embodiment of the present application, Figure 5 a schematic diagram of a disc paper guiding device provided by an embodiment of the present application from another perspective.

[0072] In some embodiments, the paper disc contact rod 1 is capable of moving relative to the clamping rod 2, and the moving direction includes a third direction close to the clamping rod 2 and a fourth direction away from the clamping rod 2; the disc paper guiding device further comprises:

[0073] a second adjusting assembly 5 arranged on the paper disc contact rod 1, the second adjusting assembly 5 being used to drive the paper disc contact rod 1 and the clamping rod 2 to jointly clamp the disc paper, and the second adjusting assembly 5 comprising:

[0074] a second torsional spring 501 used to drive the paper disc contact rod 1 to move in the third direction, the first end of the second torsional spring 501 being connected with the limiting seat 4;

[0075] a second adjusting piece 502 connected with the second end of the second torsional spring 501, the torque of the second torsional spring 501 being adjusted by rotating the second adjusting piece 502.

[0076] In the present embodiment, the disc paper guiding device realizes more precise control of the clamping force by further optimizing the movement mechanism of the paper disc contact rod 1 and the clamping rod 2. The paper disc contact rod 1 not only can cooperate with the clamping rod 2, but also can move independently relative to the clamping rod 2, and the moving direction includes a third direction close to the clamping rod 2 and a fourth direction away from the clamping rod 2. This design enables the paper disc contact rod 1 to flexibly adjust the position according to the characteristics of the disc paper and the actual working conditions, thereby better adapting to disc papers of different thicknesses and textures.

[0077] To achieve independent movement of the paper tray contact lever 1 and provide corresponding clamping force adjustment function, the device introduces a second adjustment assembly 5. The assembly is provided on the paper tray contact lever 1, and the core components include a second torsion spring 501 and a second adjustment piece 502. The second torsion spring 501 is used to drive the paper tray contact lever 1 to move in the third direction, i.e., to approach the clamping lever 2, so as to complete the clamping action on the paper tray together with the clamping lever 2. The first end of the second torsion spring 501 is connected with the limiting seat 4, which provides a stable support point for the torsion spring, ensuring that it can maintain stable elastic force output during the working process. The second adjustment piece 502 is connected with the second end of the second torsion spring 501, and by rotating the second adjustment piece 502, the torque of the second torsion spring 501 can be adjusted, and then the clamping force of the paper tray contact lever 1 is changed. This adjustment mechanism enables the operator to flexibly adjust the clamping force according to actual needs to adapt to the strict requirements of different paper trays on the clamping force.

[0078] Further, the rotatable characteristics of the paper tray contact lever 1 and the clamping lever 2 provide important guarantee for the flexibility and adaptability of the device. This design not only enables the paper tray contact lever 1 and the clamping lever 2 to freely adjust the position in different directions, but also enables independent adjustment of the clamping force through the adjustment assembly. Through the cooperative action of the first adjustment assembly 3 and the second adjustment assembly 5, the paper tray guiding device can realize bidirectional adjustment of the clamping force, so as to better cope with the characteristic differences of different paper trays and improve the reliability and adaptability of the device. This structural design not only solves the problem of paper tray damage or falling caused by improper clamping force in traditional paper guiding devices, but also significantly improves the applicability of the paper tray guiding device in diversified production environments.

[0079] In some cases, the first direction is the direction when the clamping lever 2 rotates counterclockwise, and the third direction is the direction when the paper tray contact lever 1 rotates counterclockwise.

[0080] In some embodiments, the limiting seat 4 is located between the first torsion spring 301 and the second torsion spring 501, and the center line of the first torsion spring 301 and the second torsion spring 501 passes through the limiting seat 4.

[0081] In this embodiment, the paper tray guiding device realizes the sharing and reasonable configuration of the first torsion spring 301 and the second torsion spring 501 by optimizing the spatial layout of the limiting seat 4. The limiting seat 4 is ingeniously arranged between the first torsion spring 301 and the second torsion spring 501, so that the center line of the two torsion springs passes through the limiting seat 4. This design not only provides a stable support point for the two torsion springs, ensuring that the torsion springs can maintain stable elastic force output during the working process, but also realizes efficient use of space through sharing of the limiting seat 4.

[0082] The device is compact in structure by placing the limiting seat 4 between the two torsion springs. This layout enables the first torsion spring 301 and the second torsion spring 501 to work together in a limited space, avoiding the problems of structural complexity and space waste caused by separately arranging the limiting seat. At the same time, this design of sharing the limiting seat also provides protection for the overall stability of the device, so that the paper tray contact lever 1 and the clamping lever 2 can maintain precise positioning and reliable clamping force adjustment function during movement.

[0083] It should be noted that the first adjusting assembly 3 and the second adjusting assembly 5 are the same in composition. The following will take the first adjusting assembly 3 as an example for description, and the description is also applicable to the second adjusting assembly 5, which will not be described again.

[0084] As an option, the first adjusting member 302 is provided with a torsion spring limiting structure connected with the second end of the first torsion spring 301. When the first adjusting member 302 rotates, the torsion spring limiting structure drives the second end of the first torsion spring 301 to move, and since the first end of the first torsion spring 301 is fixed on the limiting seat 4, the first torsion spring 301 is contracted or relaxed, realizing the adjustment of the torque of the first torsion spring 301.

[0085] Specifically, the clamping lever 2 is arranged on the swing lever 6 through a rotating shaft, the first torsion spring 301 is sleeved on the rotating shaft, the first end of the first torsion spring 301 is fixed on the limiting seat 4 on the swing lever 6, and the second end of the first torsion spring 301 is fixed on the torsion spring limiting structure on the first adjusting member 302. The torque of the first torsion spring 301 is adjusted by rotating the first adjusting member 302, and the acting force of the first torsion spring 301 can be transmitted to the clamping lever 2.

[0086] As an option, the first adjusting member 302 is connected with the clamping lever 2, and then the acting force of the first torsion spring 301 is transmitted to the clamping lever 2.

[0087] In some cases, a ratchet is arranged between the first adjusting member 302 and the clamping lever 2. When adjusting the torque of the first torsion spring 301, the first adjusting member 302 can be manually rotated to overcome the action force of the ratchet, at which time the first adjusting member 302 can rotate relative to the clamping lever 2 and adjust the first torsion spring 301; after adjustment, the action force of the ratchet can keep the fixed state of the first adjusting member 302 and the clamping lever 2, so that the acting force of the first torsion spring 301 is transmitted to the clamping lever 2.

[0088] In some cases, the first adjusting member 302 is divided into a static part and a dynamic part. The static part is fixedly connected with the clamping rod 2, and the dynamic part can rotate relative to the static part and be locked. The locking mode can be a ratchet or a latch. The dynamic part is provided with a torsion spring limiting structure connected with the second end of the first torsion spring 301. When adjusting the torque of the first torsion spring 301, the force of the ratchet can be overcome, or the locking between the static part and the dynamic part is released, so that the dynamic part can be manually rotated. After the adjustment is completed, the force of the ratchet or the locking between the static part and the dynamic part can keep the first adjusting member 302 fixed with the clamping rod 2, so that the force of the first torsion spring 301 is transmitted to the clamping rod 2.

[0089] In some cases, the first adjusting member 302 can also be connected with the clamping rod 2 through a fastener. Specifically, when adjusting the torque of the first torsion spring 301, the fastener is loosened, so that the first adjusting member 302 can rotate freely. After the adjustment is completed, the fastener is locked, so that the first adjusting member 302 is fixed with the clamping rod 2, and the force of the first torsion spring 301 is transmitted to the clamping rod 2.

[0090] In some embodiments, the paper tray paper guiding device further comprises:

[0091] a swing rod 6;

[0092] In some embodiments, the paper tray paper guiding device further comprises:

[0093] In this embodiment, the paper tray paper guiding device further introduces a swing rod 6 for supporting and realizing the rotating function of the clamping rod 2. The clamping rod 2 is rotatably arranged on the swing rod 6, and the first adjusting assembly 3 corresponds to the clamping rod 2 for adjusting the clamping force thereof. This design enables the clamping rod 2 to rotate flexibly under the support of the swing rod 6, thereby realizing the clamping and releasing actions of the paper tray. Through the arrangement of the swing rod 6, the movement of the clamping rod 2 is more stable, and at the same time, the swing rod 6 provides an effective force transmission path for the first adjusting assembly 3, ensuring that the adjustment of the clamping force can accurately act on the clamping rod 2.

[0094] In addition to the above embodiment, the paper tray paper guiding device can also adopt another structural layout: the paper tray contact rod 1 and the clamping rod 2 are both rotatably arranged on the swing rod 6. In this case, the first adjusting assembly 3 still corresponds to the clamping rod 2 for adjusting the clamping force thereof, and the second adjusting assembly 5 corresponds to the paper tray contact rod 1 for adjusting the movement and clamping force thereof. This design further enhances the flexibility and adaptability of the device, enabling the paper tray contact rod 1 and the clamping rod 2 to independently adjust their movement and clamping force, thereby better adapting to the characteristics of different paper trays and complex working condition requirements.

[0095] In some embodiments, the paper disc contact rod 1 is provided with a first side 101, and a paper clamping groove 102 is arranged on the first side 101, which is used to cooperate with the clamping rod 2 to achieve clamping of the disc paper.

[0096] In some embodiments, the paper disc contact rod 1 is provided with a second side 103 for contacting the paper disc, and a contact sharp corner 104 is formed between the first side 101 and the second side 103, which is used to contact the opening tape of the disc paper.

[0097] The paper disc contact rod 1 is provided with a clamping groove 105, and the clamping rod 2 is provided with a clamping part 201; when the clamping part 201 is clamped into the clamping groove 105, the clamping rod 2 is separated from the paper clamping groove 102; when the contact sharp corner 104 is pushed by the opening tape, the clamping part 201 exits the clamping groove 105, and the clamping rod 2 cooperates with the paper clamping groove 102.

[0098] In this embodiment, the design of the paper disc contact rod 1 has a unique structure and function to achieve efficient clamping and paper guiding of the disc paper. The paper disc contact rod 1 is provided with a first side 101 and a second side 103, wherein the first side 101 is provided with a paper clamping groove 102, and the second side 103 forms a contact sharp corner 104 with the first side 101. This design allows the paper disc contact rod 1 to perform different functions at different stages.

[0099] After the paper disc contact rod 1 contacts the disc paper on the paper disc, the paper disc starts to rotate. At this time, the opening tape at the end of the disc paper has not yet rotated to the contact sharp corner 104. In this state, because the clamping part 201 is clamped into the clamping groove 105, the clamping rod 2 is in a separated state from the paper disc contact rod 1. This separation state is achieved through the cooperation of the clamping part 201 and the clamping groove 105, ensuring that the clamping rod 2 does not interfere with the paper disc contact rod 1 during the initial rotation of the paper disc, thereby preparing for the subsequent clamping action.

[0100] As the paper disc continues to rotate, the opening tape gradually approaches the contact sharp corner 104. When the opening tape contacts the contact sharp corner 104, the opening tape exerts a pushing force on the contact sharp corner 104. This pushing force causes the paper disc contact rod 1 to displace, which in turn causes the clamping part 201 to exit the clamping groove 105. At this time, the separation of the clamping part 201 and the clamping groove 105 releases the restriction on the clamping rod 2 and the paper disc contact rod 1.

[0101] After the locking portion 201 exits the card slot 105, the clamping lever 2 and the paper disc contact lever 1 are no longer restricted, and they begin to move towards each other under the elastic force of the second torsional spring 501 and the first torsional spring 301. The elastic force of the second torsional spring 501 and the first torsional spring 301 drives the clamping lever 2 and the paper disc contact lever 1 to move closer to each other until the lever portion of the clamping lever 2 cooperates with the paper clamping groove 102 of the paper disc contact lever 1. This cooperation enables the clamping lever 2 and the paper disc contact lever 1 to tightly hold the unsealed opening of the paper disc, thereby completing the clamping action.

[0102] After the clamping is completed, the subsequent paper guiding action can be performed by the robot, i.e., the paper strip is guided into the equipment.

[0103] The advantage of this design is that through the cooperation of the locking portion 201 and the card slot 105, and the contact of the contact sharp corner 104 with the unsealed opening adhesive tape, the automatic separation and cooperation of the clamping lever 2 and the paper disc contact lever 1 is achieved. This automatic clamping mechanism not only improves the efficiency and reliability of clamping, but also reduces manual intervention and reduces the difficulty of operation. At the same time, the elastic force of the second torsional spring 501 and the first torsional spring 301 ensures the rapidity and stability of the clamping action, so that the device can stably operate under different working conditions, meeting the high precision and high efficiency requirements of the tobacco industry for paper guiding operation.

[0104] In some embodiments, the paper disc paper guiding device further comprises:

[0105] The electric cylinder 7 is provided with an electric cylinder push rod 701, which is used to push the clamping lever 2 so that the locking portion 201 on the clamping lever 2 is inserted into the card slot 105 after the clamping lever 2 is separated from the paper clamping groove 102.

[0106] In this embodiment, the device further comprises an electric cylinder 7 provided with an electric cylinder push rod 701. The main function of the electric cylinder push rod 701 is to push the clamping lever 2 so that it is separated from the paper clamping groove 102 of the paper disc contact lever 1, and the locking portion 201 on the clamping lever 2 is inserted into the card slot 105 of the paper disc contact lever 1. This design provides an active control and reset mechanism for the device.

[0107] Specifically, when it is necessary to separate the clamping lever 2 from the paper disc contact lever 1, the electric cylinder push rod 701 of the electric cylinder 7 is extended to push the clamping lever 2 so that it is separated from the paper clamping groove 102. At this time, the locking portion 201 on the clamping lever 2 can be smoothly inserted into the card slot 105 of the paper disc contact lever 1, thereby realizing the fixation of the clamping lever 2 and the paper disc contact lever 1.

[0108] In some cases, the middle part of the clamping rod 2 is connected to the swing rod 6 through a rotating connection, which allows the clamping rod 2 to rotate around the connection point in the middle. The first end of the clamping rod 2 is connected to the electric cylinder push rod 701, and the electric cylinder 7 directly drives the rotation of the clamping rod 2 through the action of the push rod. The second end of the clamping rod 2 is provided with a rod part, which is the key part of the cooperation between the clamping rod 2 and the paper disc contact rod 1.

[0109] As an option, the rod part of the second end of the clamping rod 2 is provided with a rubber sleeve 13, which increases the friction with the paper strip during clamping.

[0110] In some embodiments, the paper disc paper guiding device further comprises:

[0111] A connecting plate 8 is provided for connection with the robot, and the connecting plate 8 is provided with a bearing 801;

[0112] A swing rod 6 is provided on the connecting plate 8 through the bearing 801, and the swing rod 6 is connected to the paper disc contact rod 1;

[0113] A paper disc sensing assembly 9 is provided for detecting the contact state of the paper disc contact rod 1 with the paper disc and sending signals to the robot to adjust the position of the paper disc paper guiding device, and the paper disc sensing assembly 9 comprises:

[0114] A swing piece 901 is provided on the swing rod 6;

[0115] A sensor 902 is provided on the connecting plate 8, and the sensor 902 is used to detect the position of the swing piece 901.

[0116] In this embodiment, the paper disc paper guiding device further optimizes the detection mechanism of the contact state of the paper disc contact rod 1 with the paper disc, and through the introduction of the connecting plate 8, the swing rod 6 and the paper disc sensing assembly 9, the precise monitoring and automatic adjustment of the contact state are realized.

[0117] The connecting plate 8 is a connecting component between the paper disc paper guiding device and the robot, and is provided with a bearing 801. The swing rod 6 is rotatably provided on the connecting plate 8 through the bearing 801, and is connected to the paper disc contact rod 1. This structure design allows the paper disc contact rod 1 to be adjusted in position under the control of the robot, while allowing it to produce relative motion when it contacts the paper disc.

[0118] The paper disc sensing assembly 9 is the core part of this embodiment, which is used to detect the contact state of the paper disc contact rod 1 with the paper disc and feed back the relevant information to the robot. The paper disc sensing assembly 9 comprises a swing piece 901 and a sensor 902. The swing piece 901 is arranged on the swing rod 6 and moves synchronously with the swing rod 6; the sensor 902 is used to detect the position change of the swing piece 901.

[0119] In use, the robot controls the position of the paper tray guiding device to gradually bring the paper tray into contact with the paper tray contact rod 1. When the paper tray contact rod 1 contacts the paper tray, the paper tray contact rod 1 is driven to rotate the swing rod 6 relative to the connecting plate 8 under the action of the paper tray. This rotation is transmitted to the swing plate 901, causing a change in its position. The sensor 902 can sensitively detect the rotation of the swing plate 901 and convert this change into an electrical signal to send to the robot. After receiving the signal, the robot determines that the paper tray contact rod 1 has contacted the paper tray, preparing for subsequent clamping operations.

[0120] As an option, the sensor 902 can be a slot photoelectric sensor. The slot photoelectric sensor has the characteristics of simple structure, fast response speed, and high detection accuracy. In this case, the swing plate 901 can enter and exit the detection area of the slot photoelectric sensor.

[0121] In a specific embodiment, for the operation process of the paper tray guiding device, the robot first controls the paper tray guiding device to approach the paper tray until the paper tray contact rod 1 contacts the paper tray, the sensor 902 outputs a signal, and the contact action is completed. Subsequently, the paper tray is actively rotated until the opening adhesive tape contacts the contact tip angle 104 of the paper tray contact rod 1, causing the paper tray contact rod 1 to move, the clamping rod 2 and the paper tray contact rod 1 are released from the clamping of the clamping rod 2 and the paper tray contact rod 1, and the clamping rod 2 and the paper tray contact rod 1 are released from the clamping of the clamping rod 2 and the paper tray contact rod 1. Under the action of the first torsional spring 301 and the second torsional spring 501, the paper tray is clamped by the paper tray contact rod 1 and the clamping rod 2. Finally, the robot controls the overall movement of the paper tray guiding device to guide the clamped paper tray to complete the entire paper guiding process.

[0122] In some embodiments, the paper tray guiding device further comprises:

[0123] The support seat 10 is provided on the connecting plate 8.

[0124] The adjusting knob 11 is threadedly connected with the support seat 10.

[0125] The spring 12 has a first end connected with the adjusting knob 11 and a second end connected with the swing rod 6. The length of the spring 12 is adjusted by rotating the adjusting knob 11.

[0126] In this embodiment, the paper tray guiding device further introduces a support seat 10, an adjusting knob 11, and a spring 12 to optimize the detection sensitivity of the paper tray contact rod 1 to the contact state of the paper tray. The support seat 10 is provided on the connecting plate 8 to provide a mounting base for the adjusting knob 11. The adjusting knob 11 is threadedly connected with the support seat 10. The first end of the spring 12 is connected with the adjusting knob 11, and the second end is connected with the swing rod 6. By rotating the adjusting knob 11, the length of the spring 12 can be adjusted, and the elastic force exerted by the spring 12 on the swing rod 6 can be changed.

[0127] Since the contact detection of the paper disc by the paper disc contact lever 1 is realized by the movement of the swing lever 6 relative to the connecting plate 8 driven by the paper disc contact lever 1, the elastic force of the spring 12 directly affects the movement sensitivity of the swing lever 6. When the paper disc contact lever 1 contacts the paper disc, the swing lever 6 needs to overcome the force of the spring 12 to move. Therefore, by adjusting the knob 11 to change the length of the spring 12, the elastic force of the spring 12 can be adjusted, thereby changing the detection sensitivity of the paper disc contact. Specifically, reducing the elastic force of the spring 12 can improve the detection sensitivity, making it easier to perceive the contact between the paper disc contact lever 1 and the paper disc; while increasing the elastic force can reduce the sensitivity and improve the stability of the detection.

[0128] In some embodiments, the device further comprises a proximity switch arranged on the swing lever 6 for detecting the position of the clamping lever 2. This design is crucial for the normal operation of the paper disc guiding device. Specifically, the proximity switch detects the position of the clamping lever 2 to determine whether the paper disc has been successfully clamped by the paper disc contact lever 1 and the clamping lever 2. If the proximity switch detects that the clamping lever 2 is in the correct position, it means that the paper disc has been clamped, and the device can continue to perform the paper guiding operation; otherwise, if the position is detected to be incorrect, it means that the paper disc may not be clamped correctly, and the robot can adjust the position of the device or perform other operations to ensure accurate clamping of the paper disc. Combined with the detection of the contact state of the paper disc by the sensor, the device realizes double monitoring of the contact and clamping states, improves the degree of automation, reduces the risk of production failure, and improves the continuity and stability of production.

[0129] The present application also provides a paper disc guiding system, which comprises a robot and the above-mentioned paper disc guiding device, and the robot is provided with a mechanical arm connected to the paper disc guiding device.

[0130] In this embodiment, the present application further provides a paper disc guiding system, which not only comprises the above-mentioned paper disc guiding device, but also is equipped with a robot. The robot is connected to the connecting plate 8 of the paper disc guiding device through its mechanical arm, and this connection mode enables the robot to accurately control the position and posture of the paper disc guiding device, thereby realizing efficient paper guiding operation.

[0131] More importantly, the robot is connected with the electrical components in the disc paper leading device, and this connection is the core of the whole system automation. Specifically, the robot establishes a signal path with the sensor 902, the proximity switch, and the electric cylinder 7. The sensor 902 can detect whether the paper disc contact rod 1 is in contact with the paper disc in real time and feed back this information to the robot. The proximity switch is used to detect the position of the clamping rod 2, ensuring that the clamping action between the clamping rod 2 and the paper disc contact rod 1 is accurate, and at the same time, it is equivalent to detecting whether the adhesive tape at the unsealing opening of the paper disc has been triggered. The electric cylinder 7 resets the clamping rod 2 and the paper disc contact rod 1 through the action of its electric cylinder push rod 701, and this process is also precisely controlled by the robot.

[0132] Through this signal connection, the robot can adjust the action of the mechanical arm in real time according to the signals fed back by the sensor 902 and the proximity switch, thereby accurately controlling the position and posture of the disc paper leading device. At the same time, the robot can also control the action of the electric cylinder 7 to ensure that the resetting between the clamping rod 2 and the paper disc contact rod 1 is completed in a timely manner. This highly automated control system not only improves the efficiency and accuracy of the paper leading operation, but also reduces manual intervention, reduces labor intensity, and improves the continuity and stability of production.

[0133] In summary, the disc paper leading system provided by the present application realizes highly automated paper leading operation through the signal connection between the robot and the electrical components in the disc paper leading device. This system not only improves production efficiency, but also enhances the reliability and stability of the entire system, making it better meet the high-precision and high-efficiency requirements of the tobacco industry for paper leading operations.
