Description

Technical Field

[0001] This application relates to the field of tape and paper tube processing equipment technology, and in particular to a tape and paper tube clamping mechanism. Background Technology

[0002] In the production of adhesive tape paper tubes, to ensure the smooth progress of subsequent processing steps, such as precise cutting, printing, or other operations, the adhesive tape paper tubes need to be accurately positioned and fixed. Traditional paper tube positioning and clamping methods often have some shortcomings, such as insufficient positioning accuracy, which can easily lead to paper tube displacement during processing and affect product quality; uneven clamping force, which may damage the surface of the paper tube; and poor adaptability to paper tubes of different diameters or lengths, failing to meet diverse production needs.

[0003] While some existing tape-based paper tube clamping mechanisms can perform the basic function of clamping paper tubes, they lack effective synchronization and coordination when used in conjunction with pushing devices. This causes the paper tubes to wobble or tilt during the pushing process, thus affecting production efficiency and product quality. In addition, some clamping mechanisms have complex structures, are inconvenient to operate, and are difficult to adjust for different specifications of paper tubes, limiting their application range in actual production.

[0004] Therefore, we propose a tape paper tube clamping mechanism. Utility Model Content

[0005] The main objective of this application is to provide a tape paper tube clamping mechanism, which aims to solve the problem of lack of effective synchronization and coordination in the positioning, clamping and use of tape paper tubes in conjunction with the pushing device in the prior art.

[0006] To achieve the above objectives, this application provides a tape and paper tube clamping mechanism, comprising: a mounting frame, and a tape and paper tube clamping member and a tape and paper tube finished product pusher disposed within the mounting frame; wherein the tape and paper tube clamping member is located above the tape and paper tube finished product pusher.

[0007] The tape-paper tube finished product pusher is provided with a movable slide rail at one end. The movable slide rail is provided with a paper tube finished product feeding platform that slides along its long axis. One end of the paper tube finished product feeding platform is connected to an external drive unit. A central positioning shaft extends axially from the other opposite end of the paper tube finished product feeding platform. The tape-paper tube clamping component is provided in the mounting frame on the side close to the drive unit, and the clamping part of the tape-paper tube clamping component faces the paper tube finished product feeding platform.

[0008] Preferably, the tape paper tube clamping component includes: a screw adjustment mechanism fixedly mounted on the long axis of the mounting frame, and a paper tube finished product clamping claw slidably mounted on the screw adjustment mechanism. The paper tube finished product clamping claw includes: a fixed plate, on which a pushing member is provided. The pushing member is a cylinder or a hydraulic cylinder. The piston rod of the pushing member passes vertically downward through the positioning hole of the fixed plate and is fixedly connected to the clamping part on its lower side. Guide plates are also provided on both sides of the clamping part. Linear bearings are also installed in the guide plates. The linear bearings cooperate with guide shafts provided on both sides of the fixed plate. The guide shafts pass through the linear bearings and are connected to the limiting blocks on both sides of the clamping part.

[0009] Preferably, the clamping part includes a first clamping part and a second clamping part, the first clamping part and the second clamping part are located at both ends of the lower side of the fixing plate and are symmetrically arranged with respect to the central axis of the fixing plate. The first clamping part and the second clamping part have a tendency to move towards each other through the linear pusher arranged above them, and the first clamping part and the second clamping part have the same structure.

[0010] Preferably, the first clamping part includes: a mounting plate, the mounting plate being fixedly connected to the piston rod of the pusher, a sliding rail being fixedly mounted on the outer wall of the mounting plate, a movable slider being slidably mounted on the sliding rail, a gripper mounting plate being provided on the movable slider, and first clamping blocks being arranged side by side along the long axis of the gripper mounting plate, and the second clamping block in the second clamping part being a projection of the first clamping block.

[0011] Preferably, flexible rollers are provided on the inner sides of both the first clamping block and the second clamping block, and a positioning roller is fixedly connected below the mounting plate. The flexible rollers and the positioning rollers cooperate to form a triangular positioning space for the paper tube.

[0012] Preferably, the inner sides of the first clamping block and the second clamping block are provided with arc-shaped positioning grooves that are projected onto each other, forming an arched clamping area.

[0013] Preferably, a guide device is provided between the paper tube finished product feeding table and the driving component. The guide device is located between the tape paper tube clamping component and the paper tube finished product feeding table, and the guiding direction of the guide device is parallel to the moving direction of the paper tube finished product feeding table.

[0014] Preferably, the central positioning shaft is coaxially arranged with the paper tube finished product feeding table, and its outer circumferential surface is provided with a positioning protrusion that matches the inner diameter of the paper tube, which is used to accurately position the paper tube at the center during the paper tube finished product pushing process.

[0015] Preferably, the positioning protrusion has at least three clamping arms that can be opened and closed relative to each other, and the inner side of the clamping arms is provided with a limiting block for positioning the finished paper tube.

[0016] Preferably, a sensor assembly, including a proximity sensor and a photoelectric sensor, is also mounted on the mounting frame.

[0017] The beneficial effects of this utility model's technical solution are as follows:

[0018] By setting a central positioning shaft coaxial with the paper tube finished product feeding platform, and providing a positioning protrusion on the outer circumference of the central positioning shaft that matches the inner diameter of the paper tube, and at least three relatively openable clamping arms and limiting blocks for positioning the finished paper tube around the outer circumference of the positioning protrusion, precise central positioning and reliable clamping of the paper tube can be achieved. With the axes of the paper guide plate shaft coinciding, the clamping arms gradually clamp the paper tube as it moves with the central positioning shaft, ensuring that the paper tube maintains a straight line motion when pushed to the tape paper tube clamping component, effectively avoiding deviation or tilting, and greatly improving the accuracy and stability of paper tube pushing and clamping.

[0019] The guiding device further enhances the guidance of the paper tube's movement. Its guiding direction is parallel to the movement direction of the finished paper tube feeding table, ensuring that the paper tube is clearly guided throughout the entire pushing process, preventing it from swaying left or right or deviating from the predetermined trajectory. This guarantees that the paper tube can reach the tape paper tube clamping part smoothly and accurately.

[0020] Using a cylinder or electric push rod mechanism as the external drive component, the paper tube feeding table reciprocates linearly along the moving slide rail through its telescopic motion, enabling continuous paper tube feeding and meeting the high-efficiency requirements of the production process. Furthermore, it can quickly adapt to different specifications of paper tubes or different production requirements, effectively reducing the difficulty and time cost of equipment debugging.

[0021] By setting a lead screw adjustment mechanism along the long axis of the mounting frame, and sliding the paper tube finished product gripper on the lead screw adjustment mechanism, flexible adjustment of the clamping component on the mounting frame is achieved. The paper tube finished product gripper uses a pusher to drive the clamping part to move up and down, where the pusher is a cylinder or hydraulic cylinder, providing a powerful and stable power output. When it is necessary to clamp the paper tube, the piston rod of the pusher moves vertically downward, causing the clamping part to firmly clamp the paper tube, ensuring that the paper tube will not accidentally fall off during production. Moreover, the combination of guide plates, central shaft holes, linear bearings, guide shafts, and limit blocks on both sides of the clamping part forms a precision guiding system.

[0029] See Figures 1-3This utility model proposes a tape and paper tube clamping mechanism, including: a mounting frame 100, and a tape and paper tube clamping member 200 and a tape and paper tube finished product pusher 300 disposed within the mounting frame 100; the tape and paper tube clamping member 200 is located above the tape and paper tube finished product pusher 300, one end of the tape and paper tube finished product pusher 300 is provided with a movable slide rail 301, and a paper tube finished product feeding table 302 that slides along its long axis is provided on the movable slide rail 301. One end of the paper tube finished product feeding table 302 is connected to an external driving member 400, and the other opposite end of the paper tube finished product feeding table 302 has a central positioning column 303 extending axially. The tape and paper tube clamping member 200 is provided with... On the side of the mounting frame 100 near the drive component 400, the clamping part 2024 of the tape paper tube clamp 200 faces the paper tube finished product feeding table 302; the center positioning shaft 303 is coaxially arranged with the paper tube finished product feeding table 302, and its outer circumferential surface is provided with a positioning protrusion 304 that matches the inner diameter of the paper tube, which is used to accurately position the paper tube in the center during the paper tube finished product pushing process. The outer circumference of the positioning protrusion 304 is provided with at least three clamping arms 305 that can be opened and closed relative to each other. The inner side of the clamping arm 305 is provided with a limiting block 306 for positioning the paper tube finished product position, ensuring that the paper tube can maintain linear movement when it is pushed to the tape paper tube clamp 200, and avoiding deviation or tilting.

[0030] Furthermore, a guide device 500 is provided between the paper tube finished product feeding table 302 and the drive member 400. The guide device 500 is located between the tape paper tube clamping member 200 and the paper tube finished product feeding table 302, and the guiding direction of the guide device 500 is parallel to the moving direction of the paper tube finished product feeding table 302. This is to ensure that the paper tube can maintain a straight movement when it is pushed to the tape paper tube clamping member 200, and to avoid deviation or tilting.

[0031] The external drive unit 400 is a cylinder or electric push rod mechanism, which pushes the paper tube finished product feeding table 302 to reciprocate linearly along the moving slide rail 301 through its telescopic movement, thereby realizing the continuous pushing of the paper tube; when it is necessary to adjust the pushing position or angle of the paper tube, the stroke of the paper tube finished product feeding table 302 can be limited by adjusting the limit block 306 on the mounting frame 100, thereby accurately controlling the pushing distance and direction of the paper tube.

[0032] In this embodiment, by setting the central positioning shaft 303 coaxial with the paper tube finished product feeding table 302, and setting a positioning protrusion 304 adapted to the inner diameter of the paper tube on the outer circumferential surface of the central positioning shaft 303, and setting at least three relatively openable clamping arms 305 and limiting blocks 306 for positioning the finished paper tube on the outer circumference of the positioning protrusion 304, precise central positioning and reliable clamping of the paper tube can be achieved. With the axis of the paper guide plate 2025 shaft coinciding, the clamping arms 305 gradually clamp the paper tube as it moves with the central positioning shaft 303, ensuring that the paper tube maintains linear motion when pushed to the tape paper tube clamping component 200, effectively avoiding deviation or tilting, and greatly improving the accuracy and stability of paper tube pushing and clamping.

[0033] Meanwhile, the guide device 500 further enhances the guidance of the paper tube's movement. Its guiding direction is parallel to the moving direction of the finished paper tube feeding table 302, ensuring that the paper tube is always clearly guided throughout the entire pushing process, preventing it from swaying left or right or deviating from the predetermined trajectory. This ensures that the paper tube can reach the tape paper tube clamp 200 smoothly and accurately.

[0034] Using a cylinder or electric push rod mechanism as the external driving component 400, the paper tube finished product feeding table 302 is pushed along the moving slide rail 301 in a reciprocating linear motion through its telescopic movement, which can realize the continuous feeding of paper tubes and meet the high-efficiency requirements of the production process. It can also quickly adapt to different specifications of paper tubes or different production requirements, effectively reducing the difficulty of equipment debugging and time costs.

[0035] In one embodiment, the tape paper tube clamping member 200 includes: a screw adjustment mechanism 201 fixedly mounted on the long axis of the mounting frame 100, and a paper tube finished product clamping jaw 202 slidably mounted on the screw adjustment mechanism 201. The paper tube finished product clamping jaw 202 includes: a fixing plate 2021, on which a pushing member 2023 is provided. The pushing member 2023 is a cylinder or a hydraulic cylinder. The piston rod of the pushing member 2023 passes vertically downward through the positioning hole of the fixing plate 2021 and is fixedly connected to the clamping part 2024 on its lower side. Guide plates 202 are also provided on both sides of the clamping part 2024. 5. A central shaft hole 2022 is provided in the guide plate 2025. A linear bearing 2026 is also installed in the central shaft hole 2022. The linear bearing 2026 cooperates with the guide shafts 2027 provided on both sides of the fixed plate 2021. The guide shafts 2027 pass through the linear bearings 2026 and are connected to the limiting blocks 306 on both sides of the clamping part 2024. When the pusher 2023 drives the clamping part 2024 to move up and down, the guide shafts 2027 and the linear bearings 2026 ensure that the clamping part 2024 moves vertically along the central axis of the fixed plate 2021, thereby ensuring the accuracy and stability of the clamping action.

[0036] In this embodiment, by providing a lead screw adjustment mechanism 201 along the long axis of the mounting frame 100, and slidingly mounting the paper tube finished product gripper 202 on the lead screw adjustment mechanism 201, flexible adjustment of the gripper on the mounting frame 100 is achieved. Operators can adjust the position of the paper tube finished product gripper 202 on the mounting frame 100 by rotating the lead screw according to the diameter and length of different specifications of paper tubes, so that it better cooperates with the paper tube finished product pusher, thereby adapting to different production needs and improving the versatility and adaptability of the mechanism.

[0037] The paper tube finished product gripper 202 uses a pusher 2023 to drive the clamping part 2024 to move up and down. The pusher 2023 is a cylinder or hydraulic cylinder, providing powerful and stable power output. When it is necessary to clamp the paper tube, the piston rod of the pusher 2023 moves vertically downward, causing the clamping part 2024 to firmly clamp the paper tube, ensuring that the paper tube will not accidentally fall off during the production process. Moreover, the combination of the guide plate 2025, the central shaft hole 2022, the linear bearing 2026, the guide shaft 2027, and the limit block 306 on both sides of the clamping part 2024 forms a precision guiding system.

[0038] When the pusher 2023 drives the clamping part 2024 to move up and down, the guide shaft 2027 and the linear bearing 2026 can ensure that the clamping part 2024 moves strictly vertically along the central axis of the fixed plate 2021, avoiding tilting or shaking during the clamping process. This ensures the accuracy and stability of the clamping action, effectively reduces the problem of paper tube damage or production interruption caused by unstable clamping, and greatly improves production efficiency and product quality.

[0039] See Figure 4 In one embodiment, the clamping portion 2024 includes a first clamping portion 2028 and a second clamping portion 2029. The first clamping portion 2028 and the second clamping portion 2029 are located at opposite ends of the lower side of the fixing plate 2021 and are symmetrically arranged with respect to the central axis of the fixing plate 2021. The first clamping portion 2028 and the second clamping portion 2029 have a tendency to move towards each other via a linear actuator 2020 disposed above them. When the linear actuator 2020 receives a drive signal, it generates a thrust or pull force, thereby driving the first clamping portion 2028 and the second clamping portion 2029 to move towards each other along the central axis of the fixing plate 2021.

[0040] The linear actuator 2020 is a high-precision electric or hydraulic cylinder, possessing precise position control and force output capabilities. The electric or hydraulic cylinder is equipped with displacement and pressure sensors to monitor the position and clamping force of the clamping part 2024 in real time. Upon receiving a drive signal, the control system first calculates the required pushing or pulling force, as well as the distance the clamping part 2024 needs to move, based on preset clamping parameters (such as paper tube diameter and clamping force).

[0041] In this embodiment, by setting a first clamping part 2028 and a second clamping part 2029 in the clamping part 2024, and configuring a high-precision electric cylinder or hydraulic cylinder above them as a linear actuator 2020, a more precise and stable clamping operation on the paper tube is achieved. Simultaneously, the displacement and pressure sensors installed inside the high-precision electric cylinder or hydraulic cylinder can monitor the position and clamping force of the clamping part 2024 in real time, allowing the operator to precisely control the clamping process and ensure that the clamping force and position always conform to preset clamping parameters (such as paper tube diameter, clamping force, etc.). When a drive signal is received, the control system calculates the required pushing or pulling force and the distance the clamping part 2024 needs to move based on these preset parameters, thereby achieving precise clamping of paper tubes of different specifications and expanding the applicability of the equipment.

[0042] Furthermore, the first clamping part 2028 and the second clamping part 2029 have the same structure.

[0043] The first clamping part 2028 includes: a mounting plate 20281, which is fixedly connected to the piston rod of the pusher 2023. A sliding rail 20282 is fixedly mounted on the outer wall of the mounting plate 20281. A movable slider 20283 is slidably mounted on the sliding rail 20282. A gripper mounting plate 20287 is provided on the movable slider 20283. First clamping blocks 20284 are arranged side by side on the gripper mounting plate 20287 along its long axis. The second clamping block 20285 in the second clamping part 2029 is a projection of the first clamping block 20284.

[0044] Furthermore, the first clamping block 20284 and the second clamping block 20285 are provided with arc-shaped positioning grooves 20289 that are projected onto each other, forming an arched clamping area.

[0045] In one embodiment, flexible rollers 20286 are provided on the inner sides of both the first clamping block 20284 and the second clamping block 20285, and a positioning roller 20288 is fixedly connected below the mounting plate 20281. The flexible rollers 20286 and the positioning rollers 20288 cooperate to form a triangular positioning space for the paper tube. When the clamping parts 2024 move towards each other to clamp the workpiece, the flexible rollers 20286 first contact the outer surface of the workpiece. Due to their own flexible characteristics, they can adaptively conform to the irregular shape of the workpiece surface, thereby providing a more uniform and stable clamping force and avoiding local stress concentration that could damage the workpiece.

[0046] In this embodiment, flexible rollers 20286 are provided inside the first clamping block 20284 and the second clamping block 20285, and positioning rollers 20288 are fixedly connected below the mounting plate 20281, forming a triangular positioning space for the paper tube. When the clamping part 2024 moves towards each other to clamp the workpiece, the flexible rollers 20286 first contact the outer surface of the workpiece. Due to their own flexible characteristics, they can adaptively conform to the irregular shape of the workpiece surface, thereby providing a more uniform and stable clamping force. This effectively avoids the situation where local stress concentration occurs on the workpiece and damages it, further improving the safety and reliability of the clamping operation.

[0047] The application of the flexible roller 20286 allows the clamping part 2024 to better adapt to paper tubes of different diameters and thicknesses, enhancing the versatility and adaptability of the equipment. Whether the paper tube is thin-walled or thick-walled, the clamping part 2024 provides just the right clamping force, ensuring that the paper tube will not slip or be damaged during clamping. The combined use of the flexible roller 20286 and the positioning roller 20288 not only improves clamping stability but also makes the clamping process smoother. During the opposing movement of the clamping parts 2024, the flexible roller 20286 can automatically adjust its position according to the shape change of the paper tube, reducing friction and wear that may be caused by the rigid movement of the clamping part 2024, and extending the service life of the equipment.

[0048] In one embodiment, a sensor assembly is also mounted on the mounting frame 100. The sensor assembly includes a proximity sensor and a photoelectric sensor. The proximity sensor is used to detect whether the finished paper tube is accurately fed into the designated position, while the photoelectric sensor is used to monitor whether the attitude and position of the paper tube are correct during the pushing process.

[0049] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, apparatus, article, or tape / paper tube clamping mechanism that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, apparatus, article, or tape / paper tube clamping mechanism. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, apparatus, article, or tape / paper tube clamping mechanism that includes that element.
