Description

Technical Field

[0001] This application relates to the field of tobacco machinery technology, and in particular to a paper feeding device and system. Background Technology

[0002] With the further development of industrial technology, the automation level of equipment in major domestic cigarette companies has been further improved, and the amount of manual labor for workers in cigarette production workshops will be further reduced in the future. In the cigarette production process, a continuous and stable supply of cigarette paper and tipping paper is crucial. Traditional cigarette production still requires manual paper tray replacement and then manually feeding the paper strips into the equipment.

[0003] Traditional manual paper feeding has several shortcomings. First, manual operation is inefficient, and the labor intensity is extremely high during large-scale production. Second, manual paper feeding lacks precision, failing to place the paper strip precisely at the predetermined position on the feed roller, easily leading to paper strip deviation. Robotic automated paper feeding can effectively solve these problems. However, the paper roll itself is a very fragile material, and the paper rolls required for different cigarette production processes vary significantly in thickness, width, material, and paper strip tension, each with its own strict requirements for clamping force control. During automated paper feeding, excessive clamping force can easily cause the paper strip to break or be damaged; insufficient clamping force can easily cause the paper strip to detach. Precise adjustment and control of the clamping force are necessary to meet the demands of efficient and precise paper feeding in cigarette production. Utility Model Content

[0004] The purpose of this application is to provide a paper feeding device for a paper roll, which precisely controls the movement of the clamping rod through an electric cylinder to achieve precise adjustment of the paper roll clamping force, effectively avoiding paper strip damage or detachment caused by improper clamping force, and improving the stability and reliability of paper feeding.

[0022] The paper tray contact rod has a first side surface, on which a paper clamping groove is provided. The paper clamping groove is used to engage with the rod to clamp the paper tray.

[0023] In some embodiments, the paper tray contact rod has a second side surface for contacting the paper tray, and a contact angle is formed between the second side surface and the first side surface for contacting the opening tape of the paper tray.

[0024] In some embodiments, the paper feeding device further includes:

[0025] A connecting plate for connecting to the robot, the connecting plate being equipped with bearings;

[0026] A swing arm, which is rotatably mounted on the connecting plate via the bearing, and is connected to the paper tray contact rod;

[0027] A paper tray sensing component is used to detect the contact state between the paper tray contact rod and the paper tray, and send a signal to the robot so that the robot can adjust the position of the paper tray feeding device. The paper tray sensing component includes:

[0033] The spring has its first end connected to the adjustment knob and its second end connected to the rocker arm. The length of the spring is adjusted by rotating the adjustment knob.

[0034] In some embodiments, the paper feeding device further includes:

[0035] A contact torsion spring is provided on the paper tray contact rod;

[0036] A torsion spring limiting seat is connected to the first end of the contact torsion spring;

[0037] A clamping adjustment element is connected to the second end of the contact torsion spring, and the torque of the contact torsion spring is adjusted by rotating the clamping adjustment element.

[0038] This application also provides a paper feeding system, including a robot and the aforementioned paper feeding device, wherein the robot is equipped with a robotic arm and the robotic arm is connected to the paper feeding device.

[0039] Compared to the aforementioned background technology, the paper feeding device provided in this application mainly includes a paper tray contact rod and a clamping adjustment assembly. The clamping adjustment assembly is used to clamp the paper tray together with the paper tray contact rod. The clamping adjustment assembly includes a clamping rod and an electric cylinder. The clamping rod can move relative to the paper tray contact rod, and the movement direction includes a first direction close to the paper tray contact rod and a second direction away from the paper tray contact rod. The electric cylinder is connected to the clamping rod and is used to drive the clamping rod to move along the first direction or the second direction. The clamping force of the clamping rod and the paper tray contact rod clamping the paper tray is adjusted by the electric cylinder.

[0040] In traditional paper feeding operations, manual methods are difficult to precisely control the clamping force on the paper roll. Excessive clamping force can damage the paper strip, while insufficient clamping force can cause the paper strip to detach, thus affecting the stability and reliability of paper feeding. To solve this problem, this application provides a paper roll feeding device that achieves precise control of the paper roll clamping force by introducing an electric cylinder-driven clamping adjustment component.

[0041] Specifically, the core of the paper feeding device lies in the clamping and adjusting assembly, which mainly consists of a clamping rod and an electric cylinder. The clamping rod can move relative to the paper tray contact rod, with two directions of movement: a first direction towards the paper tray contact rod and a second direction away from the paper tray contact rod. The electric cylinder is connected to the clamping rod, and by precisely controlling the extension and retraction of the electric cylinder, the clamping rod can be driven to move in either the first or second direction. When the electric cylinder pushes the clamping rod closer to the paper tray contact rod, the clamping force between the clamping rod and the paper tray contact rod increases, thus firmly clamping the paper tray; conversely, when the electric cylinder pulls the clamping rod away from the paper tray contact rod, the clamping force decreases, facilitating the release of the paper tray. This method of controlling the movement of the clamping rod through an electric cylinder makes the adjustment of the clamping force more flexible and precise, allowing for dynamic adjustment according to different types of paper trays and actual working conditions.

[0042] Furthermore, the use of electric cylinders brings greater automation and stability. Compared to traditional manual operation or mechanical clamping methods, electric cylinders offer higher driving precision and faster response, effectively avoiding clamping force instability caused by human factors or limitations of mechanical structure. This precise clamping force control not only reduces the risk of paper tape damage but also improves the continuity and reliability of the paper feeding process, thereby significantly enhancing the overall performance of the paper feeding operation.

[0043] Based on the above structural and process descriptions, it can be seen that the paper feeding device has at least the following beneficial effects: the paper feeding device precisely controls the movement of the clamping rod through an electric cylinder, thereby achieving precise adjustment of the paper clamping force, effectively avoiding paper strip damage or detachment caused by improper clamping force, and improving the stability and reliability of paper feeding.

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] To enable 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 accompanying drawings and specific embodiments.

[0064] Please refer to Figures 1 to 3 ,in, Figure 1 Schematic diagram of the paper feeding device provided in the embodiments of this application Figure 1 , Figure 2Schematic diagram of the paper feeding device provided in the embodiments of this application Figure 2 , Figure 3 Schematic diagram of the paper feeding device provided in the embodiments of this application Figure 3 .

[0065] In a first specific embodiment, the paper feeding device provided in this application mainly includes a paper tray contact rod 1 and a clamping adjustment assembly 2. The clamping adjustment assembly 2 is used to clamp the paper tray (paper strip wrapped on the paper tray) together with the paper tray contact rod 1. The clamping adjustment assembly 2 includes a clamping rod 201 and an electric cylinder 202. The clamping rod 201 can move relative to the paper tray contact rod 1, and the movement direction includes a first direction close to the paper tray contact rod 1 and a second direction away from the paper tray contact rod 1. The electric cylinder 202 is connected to the clamping rod 201 and is used to drive the clamping rod 201 to move along the first direction or the second direction. The clamping force of the clamping rod 201 and the paper tray contact rod 1 clamping the paper tray is adjusted by the electric cylinder 202.

[0066] In traditional paper feeding operations, it is difficult to precisely control the clamping force on the paper roll manually. Excessive clamping force can damage the paper strip, while insufficient clamping force can cause the paper strip to fall off, thus affecting the stability and reliability of paper feeding. To solve this problem, this application provides a paper roll feeding device that achieves precise control of the paper roll clamping force by introducing a clamping adjustment component 2 driven by an electric cylinder 202.

[0067] Specifically, the core of the paper feeding device lies in the clamping adjustment assembly 2, which mainly includes a clamping rod 201 and an electric cylinder 202. The clamping rod 201 can move relative to the paper tray contact rod 1, with the movement direction divided into a first direction towards the paper tray contact rod 1 and a second direction away from the paper tray contact rod 1. The electric cylinder 202 is connected to the clamping rod 201. By precisely controlling the extension and retraction of the electric cylinder 202, the clamping rod 201 can be driven to move in either the first or second direction. When the electric cylinder 202 pushes the clamping rod 201 closer to the paper tray contact rod 1, the clamping force between the clamping rod 201 and the paper tray contact rod 1 increases, thereby firmly clamping the paper tray; while when the electric cylinder 202 pulls the clamping rod 201 away from the paper tray contact rod 1, the clamping force decreases, making it easier to release the paper tray. This method of controlling the movement of the clamping rod 201 through the electric cylinder 202 makes the adjustment of the clamping force more flexible and precise, and can be dynamically adjusted according to different types of paper trays and actual working conditions.

[0068] Furthermore, the use of the electric cylinder 202 brings a higher degree of automation and stability. Compared with traditional manual operation or mechanical clamping methods, the electric cylinder 202 has higher driving precision and faster response speed, effectively avoiding the problem of unstable clamping force caused by human factors or limitations of mechanical structure. This precise clamping force control not only reduces the risk of paper tape damage, but also improves the continuity and reliability of the paper feeding process, thereby significantly improving the overall performance of the paper feeding operation.

[0069] Based on the above structural and process descriptions, it can be seen that the paper feeding device has at least the following beneficial effects: the paper feeding device precisely controls the movement of the clamping rod 201 through the electric cylinder 202, thereby achieving precise adjustment of the paper clamping force, effectively avoiding paper strip damage or detachment caused by improper clamping force, and improving the stability and reliability of paper feeding.

[0070] In some embodiments, the paper feeding device further includes:

[0071] The opening sensing component 3 is used to detect the contact state between the paper tray contact rod 1 and the opening tape of the paper tray, and send a signal to the robot to control the action of the electric cylinder 202.

[0072] In this embodiment, the paper feeding device further integrates an opening sensing component 3, whose core function is to detect the contact state between the paper tray contact rod 1 and the paper tray opening tape in real time. When the paper tray contact rod 1 contacts the paper tray opening tape, the opening sensing component 3 can sensitively capture this contact signal and immediately transmit the signal to the robot control system. After receiving the signal, the robot then controls the movement of the electric cylinder 202 to precisely clamp the paper tray at the position of the opening tape.

[0073] The advantage of this design lies in the fact that the introduction of the opening sensing component 3 enables the paper feeding device to automatically identify the position of the opening tape and trigger the clamping action at the appropriate time, avoiding the uncertainty and inefficiency of manual intervention. Furthermore, the design of this component does not limit the specific implementation method; it can employ direct detection, such as using a pressure sensor to sense the contact force, or indirect detection, such as using other types of sensors to monitor changes in the position of the contact rod or other relevant parameters. Whether direct or indirect detection is used, as long as the contact state of the opening tape can be monitored and subsequent actions triggered, it falls within the scope of this embodiment. This flexibility allows the paper feeding device to adapt to various application scenarios and working conditions, further improving its applicability and reliability in actual production.

[0074] In some embodiments, the paper feeding device further includes:

[0075] 4-axis lever;

[0076] The paper tray contact rod 1 is rotatably mounted on the swing arm 4. The opening sensing component 3 detects the rotation position of the paper tray contact rod 1 to obtain the contact state between the paper tray contact rod 1 and the opening tape of the paper tray.

[0077] In this embodiment, the paper feeding device further includes a swing arm 4, and the paper tray contact rod 1 is rotatably mounted on the swing arm 4. This structural design allows the paper tray contact rod 1 to rotate relative to the opening tape of the paper tray when it contacts it. The opening sensing component 3 detects the rotational position of the paper tray contact rod 1 to determine whether the paper tray contact rod 1 is in contact with the opening tape of the paper tray, thereby achieving monitoring of the contact state.

[0078] The rotational position of the paper tray contact rod 1 is closely related to whether it contacts the sealing tape. When the paper tray contact rod 1 contacts the sealing tape, it will rotate due to the resistance of the tape or other physical forces. The opening sensing component 3 can accurately detect this rotational change and convert it into a contact status signal. This rotational position-based detection method can not only accurately determine the contact status between the paper tray contact rod 1 and the sealing tape, but also avoid the wear or misjudgment problems that may be caused by direct contact detection.

[0079] Furthermore, by indirectly determining the contact state by detecting the rotational position of the paper tray contact rod 1, the implementation of the opening sensing component 3 becomes more flexible and diverse. It can employ various sensor technologies, such as photoelectric sensors, angle sensors, or proximity switches, to monitor changes in the rotation angle or position of the paper tray contact rod 1. This indirect detection method not only improves the reliability of the detection but also enhances the overall stability and durability of the device.

[0080] In some embodiments, the unsealing sensing component 3 includes:

[0081] The first pendulum plate 301 is located on the paper tray contact rod 1;

[0082] The first sensor 302 is located on the swing arm 4 and is used to detect the position of the first swing plate 301.

[0083] In this embodiment, the specific structure of the unsealing sensing component 3 is further clarified, which includes a first swing plate 301 and a first sensor 302. The first swing plate 301 is disposed on the paper tray contact rod 1, while the first sensor 302 is mounted on the swing rod 4 to detect the position change of the first swing plate 301.

[0084] When the paper tray contact rod 1 contacts the sealing tape of the paper tray, the paper tray contact rod 1 will move accordingly due to the resistance of the tape. This movement causes the first swing plate 301 to move accordingly. By detecting the position change of the first swing plate 301, the first sensor 302 can accurately determine whether the paper tray contact rod 1 is in contact with the sealing tape, thereby realizing the monitoring of the contact state.

[0085] Alternatively, the first sensor 302 can be a slotted photoelectric sensor. Slotted photoelectric sensors are characterized by simple structure, fast response speed, and high detection accuracy. In this case, the first pendulum 301 can enter and leave the detection area of ​​the slotted photoelectric sensor.

[0086] In some cases, when the first pendulum 301 enters the detection area, the slotted photoelectric sensor detects a signal change, indicating that the paper tray contact rod 1 has made contact with the sealing tape; and when the first pendulum 301 leaves the detection area, the sensor signal recovers, indicating that the contact state between the paper tray contact rod 1 and the sealing tape has changed. In this way, the sealing sensing component 3 can accurately monitor the contact state between the paper tray contact rod 1 and the sealing tape.

[0087] In some embodiments, the paper feeding device further includes:

[0088] 4-axis lever;

[0089] The clamping rod 201 is rotatably mounted on the swing arm 4, the electric cylinder 202 is mounted on the swing arm 4, the electric cylinder 202 is equipped with an electric cylinder push rod, and the electric cylinder push rod is connected to the clamping rod 201.

[0090] In this embodiment, the paper feeding device further optimizes the movement of the clamping rod 201 and its coordination with the electric cylinder 202. A swing arm 4 is introduced into the device, and the clamping rod 201 is rotatably mounted on the swing arm 4. This design allows the clamping rod 201 to rotate around the swing arm 4. Simultaneously, the electric cylinder 202 is also mounted on the swing arm 4 and connected to the clamping rod 201 via a push rod. The push rod action of the electric cylinder 202 directly drives the rotation of the clamping rod 201, thereby achieving the action of clamping or releasing the paper.

[0091] The key to this embodiment is that the clamping rod 201 moves by rotation. This design not only provides a flexible movement path for the clamping rod 201, but also achieves precise control of the clamping force through the coordinated action of the rocker arm 4 and the electric cylinder 202. The push rod action of the electric cylinder 202 can push or pull the rocker arm 4, thereby causing the clamping rod 201 to rotate relative to the rocker arm 4.

[0092] In some cases, when the electric cylinder push rod retracts, the clamping rod 201 moves closer to the paper tray contact rod 1 to increase the clamping force and firmly hold the paper tray; while when the electric cylinder push rod extends, the clamping rod 201 moves away from the paper tray contact rod 1 to reduce the clamping force and facilitate the release of the paper tray.

[0093] It should be noted that although the clamping rod 201 rotates in this embodiment, in other embodiments, the clamping rod 201 may move in other ways, such as linear movement. This variety of movement options allows the paper feeding device to be optimized and adjusted according to different application scenarios and needs, further improving the adaptability and functionality of the device.

[0094] In some embodiments, the middle part of the clamping rod 201 is rotatably connected to the swing rod 4, the first end of the clamping rod 201 is connected to the electric cylinder push rod, and the second end of the clamping rod 201 is provided with a rod portion;

[0095] The paper tray contact rod 1 has a first side surface 101, and a paper clamping groove 102 is provided on the first side surface 101. The paper clamping groove 102 is used to cooperate with the rod to clamp the paper tray.

[0096] In this embodiment, the connection method between the clamping rod 201 and the swing rod 4, as well as its cooperation with the paper tray contact rod 1, are further clarified. The middle part of the clamping rod 201 is connected to the swing rod 4 by a rotatable connection, which allows the clamping rod 201 to rotate around the connection point in its middle. The first end of the clamping rod 201 is connected to the electric cylinder push rod, and the electric cylinder 202 directly drives the rotation of the clamping rod 201 through the action of the push rod. The second end of the clamping rod 201 is provided with a rod portion, which is the key part for the clamping rod 201 to cooperate with the paper tray contact rod 1.

[0097] A paper-clamping groove 102 is provided on the first side 101 of the paper tray contact rod 1. The shape of this groove matches the rod portion of the second end of the clamping rod 201, forming a concave-convex fit structure. When the clamping rod 201 approaches the paper tray contact rod 1 under the drive of the electric cylinder 202, the rod portion and the paper-clamping groove 102 engage with each other, thereby clamping the paper tray. This concave-convex fit design not only improves the stability and reliability of clamping, but also reduces the loss of clamping force through precise mechanical matching, ensuring the accurate execution of the clamping action.

[0098] This structural design optimizes the movement of the clamping rod 201 and its interaction with the paper tray contact rod 1, making the paper tray feeding device more flexible, efficient, and stable when clamping the paper tray. This design is not only suitable for paper trays of different thicknesses and types, but also provides a reliable mechanical basis for the automated operation of the device.

[0099] Optionally, a rubber sleeve 13 is provided on the second end of the clamping rod 201 to increase the friction with the paper tape during clamping.

[0100] In some embodiments, the paper tray contact rod 1 is provided with a second side surface 103 for contacting the paper tray, and a contact tip 104 is formed between the second side surface 103 and the first side surface 101 for contacting the opening tape of the paper tray.

[0101] In this embodiment, the structural design of the paper tray contact rod 1 is further optimized to achieve precise contact and detection of the paper tray opening and sealing tape. The paper tray contact rod 1 is provided with a second side surface 103, which directly contacts the paper tray to ensure that the paper tray contact rod 1 can stably contact the paper tray. At the same time, a contact angle 104 is formed between the second side surface 103 and the first side surface 101.

[0102] When the paper tray contact rod 1 contacts the paper tray, the active rotation of the paper tray will cause the sealing tape on the tray to rotate to the paper tray contact rod 1. At this time, the contact tip 104 contacts the sealing tape. The design of the contact tip 104 ensures that sufficient resistance or reaction force is generated at the moment of contact, thereby causing the paper tray contact rod 1 to move. This movement can be a small displacement or angular change, but it is sufficient to be detected by the opening sensing component 3.

[0103] The opening sensor component 3 can accurately determine whether the contact tip 104 has made contact with the opening tape by detecting the movement of the paper tray contact rod 1. This detection process is automated and requires no manual intervention, greatly improving the efficiency and reliability of the paper feeding process. Through this design, the paper tray contact rod 1 can not only achieve stable contact with the paper tray, but also trigger subsequent paper feeding operations through the interaction between the contact tip 104 and the opening tape, ensuring the automation and precise control of the entire process.

[0104] In some embodiments, the paper feeding device further includes:

[0105] Connecting plate 5, used for connecting to the robot, is equipped with bearing 501;

[0106] The swing arm 4 is rotatably mounted on the connecting plate 5 via the bearing 501, and the swing arm 4 is connected to the paper tray contact rod 1;

[0107] The paper tray sensing component 6 is used to detect the contact state between the paper tray contact rod 1 and the paper tray, and send a signal to the robot so that the robot can adjust the position of the paper tray feeding device. The paper tray sensing component 6 includes:

[0108] The second pendulum plate 601 is located on the pendulum rod 4;

[0109] The second sensor 602 is used to detect the position of the second pendulum 601.

[0110] In this embodiment, the paper feeding device further optimizes the detection mechanism of the contact state between the paper tray contact rod 1 and the paper tray. By introducing the connecting plate 5, the swing rod 4 and the paper tray sensing component 6, accurate monitoring and automatic adjustment of the contact state are achieved.

[0111] The connecting plate 5 is the connecting component between the paper feeding device and the robot, and it is equipped with a bearing 501. The swing arm 4 is rotatably mounted on the connecting plate 5 via the bearing 501 and is connected to the paper tray contact rod 1. This structural design allows the paper tray contact rod 1 to be positioned under the control of the robot, while also allowing it to generate relative movement when it contacts the paper tray.

[0112] The paper tray sensing component 6 is the core component of this embodiment. It is used to detect the contact state between the paper tray contact rod 1 and the paper tray and to feed back the relevant information to the robot. The paper tray sensing component 6 includes a second swing plate 601 and a second sensor 602. The second swing plate 601 is mounted on the swing rod 4 and moves synchronously with the swing rod 4; the second sensor 602 is used to detect the positional changes of the second swing plate 601.

[0113] During operation, the robot controls the position of the paper feeding device, causing the paper tray contact rod 1 to gradually approach the paper tray. When the paper tray contact rod 1 contacts the paper tray, it is subjected to the force of the paper tray, causing the paper tray contact rod 1 to rotate relative to the connecting plate 5. This rotation is transmitted to the second swing plate 601, causing its position to change. The second sensor 602 can sensitively detect the rotation of the second swing plate 601 and convert this change into an electrical signal, which is then sent to the robot. After receiving the signal, the robot determines that the paper tray contact rod 1 has made contact with the paper tray, preparing for subsequent clamping operations.

[0114] Alternatively, the second sensor 602 can be a slotted photoelectric sensor. Slotted photoelectric sensors are characterized by simple structure, fast response speed, and high detection accuracy. In this case, the second pendulum 601 can enter and leave the detection area of ​​the slotted photoelectric sensor.

[0115] In one specific implementation, the operation of the paper feeding device begins with the robot controlling the device to approach the paper tray until the paper tray contact rod 1 contacts the paper tray. At this point, the second sensor 602 outputs a signal, confirming the contact. Subsequently, the paper tray rotates actively until the sealing tape contacts the contact tip 104 of the paper tray contact rod 1. At this point, the first sensor 302 outputs a signal, confirming the sealing detection. Next, the robot controls the electric cylinder 202 to clamp the paper tray via the clamping rod 201. Finally, the robot controls the overall movement of the paper feeding device, driving the clamped paper tray to perform the feeding operation, completing the entire feeding process.

[0116] In some embodiments, the paper feeding device further includes:

[0117] Support base 7 is located on connecting plate 5;

[0118] Adjustment knob 8 is threadedly connected to support base 7;

[0119] The spring 9 has its first end connected to the adjustment knob 8 and its second end connected to the rocker arm 4. The length of the spring 9 is adjusted by rotating the adjustment knob 8.

[0120] In this embodiment, the paper feeding device further incorporates a support base 7, an adjusting knob 8, and a spring 9 to optimize the detection sensitivity of the paper tray contact rod 1 to the paper tray contact state. The support base 7 is mounted on the connecting plate 5, providing a mounting base for the adjusting knob 8. The adjusting knob 8 is threadedly connected to the support base 7, and the first end of the spring 9 is connected to the adjusting knob 8, while the second end is connected to the swing rod 4. By rotating the adjusting knob 8, the length of the spring 9 can be adjusted, thereby changing the elastic force exerted by the spring 9 on the swing rod 4.

[0121] Since the contact detection of the paper tray by the paper tray contact rod 1 is achieved by driving the swing rod 4 relative to the connecting plate 5, the elastic force of the spring 9 directly affects the motion sensitivity of the swing rod 4. When the paper tray contact rod 1 contacts the paper tray, it needs to overcome the force of the spring 9 to make the swing rod 4 move. Therefore, by adjusting the knob 8 to change the length of the spring 9, the magnitude of the elastic force of the spring 9 can be adjusted, thereby changing the detection sensitivity of the paper tray contact. Specifically, reducing the elastic force of the spring 9 can improve the detection sensitivity, making it easier to detect the contact between the paper tray contact rod 1 and the paper tray; while increasing the elastic force can reduce the sensitivity and improve the stability of the detection.

[0122] In some embodiments, the paper feeding device further includes:

[0123] Contact torsion spring 10 is provided on paper tray contact rod 1;

[0124] The torsion spring limiting seat 11 is connected to the first end of the contact torsion spring 10;

[0125] The clamping adjustment member 12 is connected to the second end of the contact torsion spring 10, and the torque of the contact torsion spring 10 can be adjusted by rotating the clamping adjustment member 12.

[0126] In this embodiment, the paper feeding device further optimizes the sensitivity adjustment mechanism of the paper tray contact rod 1 during the opening and sealing detection process. By introducing the contact torsion spring 10, the torsion spring limiting seat 11 and the clamping adjustment component 12, the detection sensitivity of the paper tray contact rod 1 is precisely controlled.

[0127] A contact torsion spring 10 is mounted on the paper tray contact rod 1, with one end fixed by a torsion spring limiting seat 11 and the other end connected to a clamping adjustment member 12. The force of the contact torsion spring 10 acts directly on the paper tray contact rod 1, affecting its motion response when it contacts the paper tray opening tape. Since the detection of the opening tape depends on the minute movement generated when the paper tray contact rod 1 contacts the tape, the torque of the contact torsion spring 10 directly determines the sensitivity of the paper tray contact rod 1 to the opening tape.

[0128] The torque of the contact torsion spring 10 can be adjusted by rotating the clamping adjustment component 12. When it is necessary to increase the sensitivity of the opening detection, the torque of the contact torsion spring 10 can be reduced by rotating the clamping adjustment component 12, so that the paper tray contact rod 1 can move more easily when it contacts the opening tape, thereby triggering the opening sensing component 3 more sensitively. Conversely, when it is necessary to reduce the detection sensitivity to improve stability, this can be achieved by increasing the torque of the contact torsion spring 10.

[0129] This application also provides a paper feeding system, including a robot and the aforementioned paper feeding device, wherein the robot is equipped with a robotic arm and the robotic arm is connected to the paper feeding device.

[0130] Specifically, the robotic arm is connected to the connecting plate 5 of the paper feeding device, enabling the entire device to seamlessly interface with the robot system on the automated production line, thereby achieving automated operation.

[0131] More importantly, the robot achieves signal connection with the electrical components of the paper feeding device, a connection method that is the core of realizing the automated operation of the entire system. Through signal connection, the robot can receive detection signals from various sensors in the paper feeding device (such as the first sensor 302, the second sensor 602, etc.) and precisely control the movement of the electric cylinder 202 and the overall position adjustment of the paper feeding device based on these signals. For example, when the first sensor 302 detects the contact signal between the paper tray contact rod 1 and the sealing tape, the robot can respond quickly and control the electric cylinder 202 to perform a clamping action; when the second sensor 602 detects the contact signal between the paper tray contact rod 1 and the paper tray, it can start the paper tray rotation and perform sealing detection. This automated control based on signal connection not only improves the efficiency and accuracy of paper feeding operation, but also reduces manual intervention, enhances the continuity and stability of production, and enables the paper feeding system to better adapt to the demand for efficient and precise paper feeding in modern tobacco production.
