Description

Technical Field

[0001] This utility model relates to the field of paper core tube technology, and in particular to a paper core tube clamping device for automatic core removal. Background Technology

[0002] In the production and processing of roll materials such as paper and film, a large number of paper core tubes that need to be cored and recycled are generated. Currently, the positioning and fixing of paper core tubes before core removal mostly relies on manual operation. After the paper core tubes are transported to the core removal area by the production line, workers manually adjust and press the paper core tubes to fix them. After the external core removal equipment completes the core removal, they are manually released. However, this method relies on manual operation. After the paper core tubes are transported to the core removal area, workers need to manually adjust and press them next to the core removal equipment. This not only poses a safety hazard due to improper operation and the risk of being scratched by the core removal equipment, but also results in uneven fixing force and large positioning deviations. The paper core tubes are prone to tilting and loosening during the core removal process, leading to a decrease in core removal accuracy. Furthermore, the shaking of the paper core tubes may cause the core removal equipment to jam, affecting the operating efficiency of the production line and the core removal quality, making it difficult to adapt to the needs of modern production. Utility Model Content

[0003] Therefore, in order to overcome at least some of the defects and deficiencies in the prior art, this utility model provides a paper core tube clamping device for automatic core picking.

[0004] Specifically, the paper core tube clamping device for automatic core picking provided in this embodiment of the present invention includes: a support frame having a first sidewall; a conveying mechanism disposed near the first sidewall; a transmission structure movably connected to the first sidewall; and a clamping mechanism including: an upper main frame fixedly connected to the side of the transmission structure facing away from the support frame; and a lower main frame fixedly connected to the side of the transmission structure facing away from the support frame and located between the upper main frame and the conveying mechanism, wherein the upper main frame and the lower main frame are spaced apart along the height direction of the support frame; and a clamping mechanism. The holding assembly includes: a first clamping member fixed to the side of the upper main frame facing the lower main frame; a second clamping member fixed to the side of the lower main frame facing the upper main frame, the first clamping member and the second clamping member being arranged opposite to each other and spaced apart along the height direction of the support frame, forming a clamping area for accommodating paper core tubes between the first clamping member and the second clamping member; a clamping drive member fixed to the lower main frame, the drive end of the clamping drive member being fixedly connected to the upper main frame; and a controller electrically connected to the clamping drive member and the drive member of the conveying mechanism.

[0005] In one embodiment of the present invention, the conveying mechanism includes a plurality of conveying rollers for conveying paper core tubes, and an avoidance gap is formed between two adjacent conveying rollers, and the second clamping member is provided corresponding to the avoidance gap.

[0006] In one embodiment of this utility model, the transmission structure includes a first transmission assembly, which includes: a first transmission connector, one end of which is movably connected to the first side wall and the other end of which is fixed to the side of the upper main frame near the first side wall, the first transmission connector having a first transmission connection portion; a second transmission connector, one end of which is movably connected to the first side wall and the other end of which is fixed to the side of the lower main frame near the first side wall, the second transmission connector having a second transmission connection portion, the first transmission connection portion and the second transmission connection portion being disposed opposite to each other; and a third transmission connector, one end of which is fixed to the first side wall, the third transmission connector being tractively connected between the first transmission connection portion and the second transmission connection portion.

[0007] In one embodiment of this utility model, the first sidewall has a first end and a second end opposite to each other. The transmission structure further includes a second transmission assembly, which includes: a fourth transmission connector, one end of which is movably connected to the first sidewall and the other end of which is fixed to the side of the upper main frame near the first sidewall, the fourth transmission connector having a fourth transmission connection portion; a fifth transmission connector, one end of which is movably connected to the first sidewall and the other end of which is fixed to the side of the lower main frame near the first sidewall, the fifth transmission connector having a fifth transmission connection portion, the fourth transmission connection portion and the fifth transmission connection portion being disposed opposite to each other; and a sixth transmission connector, one end of which is fixed to the first sidewall, the sixth transmission connector being tractively connected between the fourth transmission connection portion and the fifth transmission connection portion; wherein, the first transmission assembly is disposed near the first end, and the second transmission assembly is disposed near the second end.

[0008] In one embodiment of this utility model, the first transmission connecting part and the second transmission connecting part are both racks, the third transmission connecting member is a gear, and the third transmission connecting member meshes with the first transmission connecting part and the second transmission connecting part respectively; and / or, the fourth transmission connecting part and the fifth transmission connecting part are both racks, the sixth transmission connecting member is a gear, and the sixth transmission connecting member meshes with the fourth transmission connecting part and the fifth transmission connecting part respectively.

[0009] In one embodiment of this utility model, the paper core tube clamping device for automatic core picking further includes: a slide rail disposed on the first side wall, the slide rail extending along the height direction of the support frame; and multiple sliders, the multiple sliders being fixedly connected to the side of the first transmission connector, the second transmission connector, the fourth transmission connector and the fifth transmission connector near the first side wall, the sliders being disposed corresponding to the slide rails, and the sliders being slidably connected to the slide rails.

[0010] In one embodiment of the present invention, a clamping sensor is further included, disposed on the side of the first clamping member, and the clamping sensor is electrically connected to the controller.

[0011] In one embodiment of this utility model, the number of clamping components is multiple sets, and the multiple sets of clamping components are arranged at intervals.

[0012] In one embodiment of the present invention, both the first clamping member and the second clamping member have a buffer layer on the side facing the clamping area.

The blocking structure is disposed near the output end; the positioning sensor is disposed on the blocking structure and is electrically connected to the controller.

[0014] As can be seen from the above, in this embodiment of the utility model, after the paper core tube is transported to the designated area by the conveying mechanism, the controller controls the clamping drive of the clamping mechanism to start. The clamping drive, in conjunction with the transmission structure, drives the upper main frame and the lower main frame to move synchronously in opposite directions along the height of the support frame, so that the first clamping member and the second clamping member clamp the paper core tube in opposite directions. The synchronous reverse movement design ensures that the paper core tube is subjected to balanced force, avoiding the problems of skewing and loosening when manually fixed, and providing a precise and stable core-taking benchmark for the external core-taking equipment. After the core is taken, the controller controls the drive to move in the opposite direction, driving the first clamping member and the second clamping member to move in opposite directions to release the paper core tube. After the release action is completed, the controller controls the conveying mechanism to start, and smoothly transports the core-taken paper core tube to the subsequent transfer and collection area for subsequent operations. This utility model controls the clamping mechanism through a controller. The clamping drive component, in conjunction with the transmission structure, drives the upper and lower main frames to move synchronously in opposite directions, so that the first and second clamping components clamp the paper core tube in opposite directions. It is compatible with external core-removing equipment to perform core-removing operations on the paper core tube. This not only eliminates the safety hazards of manual intervention in the clamping position, but also avoids the paper core tube from tilting and loosening, improves positioning accuracy, ensures efficient and accurate core removal, and meets the needs of modern production.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0025] See Figure 1 and Figure 2 This utility model provides a paper core tube clamping device 10 for automatic core picking. The paper core tube clamping device 10 includes, for example, a support frame 100, a conveying mechanism 200, a transmission structure 300, a clamping mechanism 400, and a controller (not shown).

[0026] Specifically, the support frame 100 is, for example, a vertical load-bearing frame structure, having a first side wall 110 for assembling various mechanisms. In this embodiment, the support frame 100 may be made of, for example, carbon steel or stainless steel, with high overall structural strength, providing a stable installation support reference for the transmission structure 300 and the clamping mechanism 400. The first side wall 110 may be, for example, a flat metal plate structure, facilitating the positioning and assembly of the transmission structure 300 and the clamping mechanism 400.

[0027] Specifically, the conveying mechanism 200 is located, for example, near the first sidewall 110, for receiving the paper core tubes output from the production line and conveying them to the core-taking position. In this embodiment, the conveying mechanism 200 may be, for example, a roller conveyor mechanism, consisting of a conveyor frame, multiple conveyor rollers, and a conveyor motor. The conveyor frame extends, for example, along the width direction of the first sidewall, and the multiple conveyor rollers are arranged parallel and spaced apart, for example, along the extension direction of the conveyor frame. The conveying mechanism 200 achieves smooth conveying of the paper core tubes by driving the rollers to rotate via a motor. Its conveying path corresponds to the clamping position of the subsequent clamping mechanism 400, ensuring that the paper core tubes can accurately reach the core-taking position. In other embodiments, the conveying mechanism 200 may also be, for example, a belt conveyor mechanism, consisting of multiple parallel and spaced belts; no specific limitation is made here.

[0028] Specifically, the transmission structure 300 is movably connected to the first sidewall 110, for example. In this embodiment, the transmission structure 300 may be, for example, a gear and rack transmission assembly or a synchronous belt transmission assembly. One end of the transmission structure 300 is movably connected to the first sidewall 110, and the other end is fixed to the clamping mechanism 400, for example. The clamping mechanism 400 includes, for example, an upper main frame 410, a lower main frame 420, a clamping assembly, and a clamping drive member 440. The upper main frame 410 is fixedly connected to the side of the transmission structure 300 facing away from the support frame 100; the lower main frame 420 is fixedly connected to the side of the transmission structure 300 facing away from the support frame 100 and is located between the upper main frame 410 and the conveying mechanism 200. The upper main frame 410 and the lower main frame 420 are spaced apart along the height direction of the support frame 100. The upper main frame 410 and the lower main frame 420 may both be, for example, long strip-shaped metal frame structures, which can provide a stable mounting carrier for the clamping assembly. In this embodiment, by setting up a transmission structure 300 in conjunction with the clamping drive component 440 to synchronously drive the upper main frame 410 and the lower main frame 420 to move in opposite directions (moving in opposite directions or moving away from each other), the clamping action of the clamping mechanism 400 is ensured to be synchronous and smooth.

[0029] The clamping assembly includes, for example, a first clamping member 431 and a second clamping member 432. The first clamping member 431 is fixed, for example, to the side of the upper main frame 410 facing the lower main frame 420, and the second clamping member 432 is fixed to the side of the lower main frame 420 facing the upper main frame 410. The first clamping member 431 and the second clamping member 432 are arranged opposite to each other and spaced apart along the height direction of the support frame 100, forming a clamping area 450 for accommodating the paper core tube. In this embodiment, the first clamping member 431 and the second clamping member 432 can be, for example, an inverted V-shaped clamping block or an arc-shaped clamping plate. The clamping surfaces of the first clamping member 431 and the second clamping member 432 can be adapted to the arc surface of the paper core tube to ensure smooth and precise clamping action. Of course, the clamping surfaces of the first clamping member 431 and the second clamping member 432 can be adaptively designed according to the surface shape of the paper core tube; specific details are not limited here.

[0030] The clamping drive 440 is fixed to the lower main frame 420, for example, and its drive end is fixedly connected to the upper main frame 410. In this embodiment, the clamping drive 440 may be, for example, a cylinder or an electric push rod, used to provide power for the relative movement of the upper main frame 410 and the lower main frame 420.

[0031] Specifically, the controller is electrically connected to the clamping drive 440 and the drive of the conveying mechanism 200, respectively. In this embodiment, the controller may be, for example, a PLC controller, capable of receiving the operating signals of each mechanism and sending control commands to achieve coordinated operation between the conveying mechanism 200 and the clamping mechanism 400, ensuring orderly connection of each link.

[0032] In this embodiment, the working principle of the paper core tube clamping device 10 for automatic core picking is as follows: When the paper core tubes output from the production line enter the conveying mechanism 200, the controller starts the conveying mechanism 200 to transport the paper core tubes to the clamping area 450. Upon reaching the clamping area 450, the controller stops the conveying mechanism 200 and simultaneously starts the clamping drive 440. The clamping drive 440 drives the upper main frame 410 downwards. The upper main frame 410 drives the connected transmission structure 300 to move synchronously. Through the transmission action of the transmission structure 300, the lower main frame 420 moves upwards, causing the first clamping... The first clamping member 431 and the second clamping member 432 move synchronously in opposite directions along the height of the support frame 100, clamping the paper core tube from both the top and bottom sides. After the external core removal equipment completes the core removal operation, the controller controls the clamping drive member 440 to move in the opposite direction, driving the upper main frame 410 and the lower main frame 420 to move in opposite directions, and the first clamping member 431 and the second clamping member 432 release the paper core tube. After the release action is completed, the core-removed paper core tube is transported to the subsequent transfer and collection area, and then each mechanism executes the next work cycle under the control of the controller.

[0033] Therefore, the paper core tube clamping device 10 for automatic core removal provided in this embodiment, through the coordinated operation of the support frame 100, conveying mechanism 200, transmission structure 300, clamping mechanism 400 and controller, realizes the automated operation of positioning and fixing the paper core tube before core removal. After core removal, the paper core tube can be stably released to adapt to subsequent transfer requirements. The clamping design with synchronous reverse movement makes the paper core tube subjected to balanced force, effectively solving the problems of skewing and loosening that are easy to occur when manually fixed, and providing a precise and stable core removal benchmark for external core removal equipment. The core removal process does not require manual intervention at the clamping station, reducing the safety hazards of manual operation, and at the same time reducing the number of manual intervention links, significantly improving the efficiency and quality of core removal operation, and meeting the automation operation requirements of modern production lines.

[0034] It should be noted that in the paper core tube clamping device 10 for automatic core removal provided in this embodiment of the present invention, the external core removal device that cooperates to complete the core removal action can be, for example, a core removal robot (not shown) in this embodiment. The core removal robot typically includes a robotic arm, a core removal execution head and a positioning detection component. The robotic arm can be fixed to the side of the support frame 100 by a bracket, and its range of motion covers the preset clamping position. The core removal execution head is adapted to the inner diameter specification of the paper core tube and can be accurately inserted into the paper core tube to complete the core removal operation.

[0035] Furthermore, the conveying mechanism 200 includes multiple conveying rollers 220 for conveying the paper core tube. A clearance gap is formed between two adjacent conveying rollers 220, and the second clamping member 432 is set corresponding to the clearance gap. Specifically, a clearance gap is formed between adjacent rollers to accommodate the lifting and lowering of the second clamping member 432. When the paper core tube is conveyed to the clamping area 450, the second clamping member 432 is located directly below this gap, without contact with the roller surface, and does not interfere with the rotation of the conveying rollers 220. When the conveying mechanism 200 conveys the paper core tube to the clamping area 450, the controller controls the clamping drive member 440 to start. The clamping drive member 440 drives the upper main frame 410 to move downward, and synchronously drives the lower main frame 420 to move upward via the transmission structure 300. The second clamping member 432 passes upward through the roller gap and clamps the paper core tube synchronously with the first clamping member 431. There is no mechanical interference throughout the process, ensuring clamping accuracy. In this way, the second clamping member 432 extends upward from the gap of the conveying roller 220 and cooperates with the first clamping member 431 to complete the clamping of the paper core tube. This not only avoids interference with the movement of the conveying roller 220, but also ensures that the clamping position accurately corresponds to the core taking position, further improving the reliability of the paper core tube positioning.

[0036] Reference Figure 3 The transmission structure 300 includes, for example, a first transmission assembly 310, which includes, for example, a first transmission connector 311, a second transmission connector 312, and a third transmission connector 313. The first transmission connector 311 has one end movably connected to the first sidewall 110 and the other end fixed to the side of the upper main frame 410 near the first sidewall 110, and has a first transmission connection portion. The second transmission connector 312 has one end movably connected to the first sidewall 110 and the other end fixed to the side of the lower main frame 420 near the first sidewall 110, and the two are spaced apart along the height direction of the support frame 100. The second transmission connector 312 has a second transmission connection portion, and the first transmission connection portion and the second transmission connection portion are arranged opposite to each other. The third transmission connector 313 has one end fixed to the first sidewall 110 and is transmissionally connected between the first transmission connector 311 and the second transmission connector 312.

[0037] In some embodiments, the first transmission connector 311 and the second transmission connector 312 may be, for example, metal sliders with racks (the first and second transmission connections are, for example, racks), and the third transmission connector 313 may be, for example, a gear that meshes with two sets of racks simultaneously, achieving reverse movement of the first and second transmission connectors through gear reversal. In other embodiments, the first and second transmission connectors may be, for example, synchronous belt pulley mounting seats (the first and second transmission connections are, for example, synchronous belt pulleys), and the third transmission connector may be, for example, a synchronous belt that winds around and connects two sets of pulleys, achieving reverse synchronous movement through belt drive. Transmission methods such as sprockets and chains, transmission rods, and connecting rods may also be used. The specific transmission method can be designed according to the actual load and accuracy requirements, and is not limited here, as long as the movement of the first transmission connector can be synchronously and reversely transmitted to the second transmission connector through the third transmission connector.

[0038] See also Figure 1 and Figure 2 The first sidewall 110 has, for example, a first end 111 and a second end 112. The transmission structure 300 also includes a second transmission assembly 320, which includes, for example, a fourth transmission connector 321, a fifth transmission connector 322, and a sixth transmission connector 323. The first transmission assembly 310 is disposed near the first end 111, and the second transmission assembly 320 is disposed near the second end 112, and they are symmetrically distributed along the width direction of the first sidewall 110.

[0039] The fourth transmission connector 321 has the same structure as the first transmission connector 311, with one end movably connected to the first side wall 110 and the other end fixed to the upper main frame 410. The fourth transmission connector 321 has a fourth transmission connection portion. The fifth transmission connector 322 has the same structure as the second transmission connector 312, with one end movably connected to the first side wall 110 and the other end fixed to the lower main frame 420. The fifth transmission connector 322 has a fifth transmission connection portion, with the fourth and fifth transmission connection portions positioned opposite each other. The sixth transmission connector 323 has the same transmission structure as the third transmission connector 313, fixed to the first side wall 110 and connecting the fourth and fifth transmission connectors. By setting two sets of transmission components, it can be ensured that the first clamping member 431 and the second clamping member 432 always maintain parallel clamping, improving the overall transmission stability and accuracy.

[0040] In this embodiment, the first transmission assembly 310 and the second transmission assembly 320 preferably adopt a gear and rack meshing structure. Specifically, the first transmission connection part and the second transmission connection part are straight racks arranged along the height direction of the first sidewall, and the third transmission connection member 313 is a gear, for example, fixed to the first sidewall 110 by a bearing seat. The gear tooth surface meshes with the rack tooth surface of the first and second transmission connection parts respectively, and the meshing clearance can be calibrated by adjusting the position of the bearing seat.

[0041] In this embodiment, both the fourth and fifth transmission connection parts are straight racks, and the sixth transmission connection 323 is a matching gear, fixed to the corresponding position on the first sidewall 110 and meshing with the rack. When the clamping drive 440 drives the upper main frame 410 to move downward, the first transmission connection 311 and the fourth transmission connection 321 move downward synchronously, the rack drives the gear to rotate, and the gear then drives the second transmission connection 312 and the fifth transmission connection 322 to move upward synchronously, realizing the reverse synchronous movement of the upper and lower main frames, so as to ensure that the clamping and releasing action of the clamping assembly is smooth, providing a balanced clamping force for clamping the paper core tube, and further ensuring the core picking accuracy.

[0042] See also Figure 3 The paper core tube clamping device 10 for automatic core removal also includes, for example, a slide rail 610 and a slider 620. The slide rail 610 is disposed on the first side wall 110 and extends along the height direction of the support frame 100. In this embodiment, the slide rail 610 can be, for example, a linear guide rail made of metal, and is fixed to the flat surface of the first side wall 110 by bolts. Its length is adapted to the travel of the transmission connector. There are multiple sliders 620, which can be, for example, sliding blocks adapted to the slide rail 610, and are respectively fixed to the side of the first transmission connector 311, the second transmission connector 312, the fourth transmission connector 321, and the fifth transmission connector 322 near the first side wall 110 by screws. The slider 620 and the slide rail 610 form a sliding engagement. When the first transmission connector 311 and the fourth transmission connector 321 move up and down with the upper main frame 410, the slider 620 connected to them slides synchronously along the slide rail 610. Similarly, when the second transmission connector 312 and the fifth transmission connector 322 move, the corresponding slider 620 also slides along the slide rail 610. The engagement between the slide rail and the slider can restrict the movement direction of the first transmission component 310 and the second transmission component 320, thereby restricting the movement direction of the clamping component and ensuring that it only moves in a straight line along the height direction of the support frame 100. This further improves the synchronicity and stability of the movement of the upper main frame 410 and the lower main frame 420, making the clamping action of the first clamping component 431 and the second clamping component 432 more precise and reliable.

[0043] See Figure 4The paper core tube clamping device 10 for automatic core removal also includes a clamping sensor 500. The clamping sensor 500 is located, for example, on the side of the first clamping member 431. In this embodiment, the clamping sensor 500 may be, for example, a limit switch, a pressure sensor, or an infrared sensor. It is electrically connected to the controller and can transmit the detection signal to the controller in real time to provide feedback on the clamping status.

[0044] In some embodiments, the clamping sensor 500 is preferably a limit switch, the end face of which corresponds to the arc bottom surface of the paper core tube to be clamped. When the clamping mechanism is activated, the paper core tube is clamped into place by the clamping component. The arc surface of the paper core tube will trigger the limit switch. After the limit switch is pressed, it generates a signal and sends it to the controller. After receiving the signal, the controller can determine that the paper core tube has been clamped and then control the clamping drive 440 to stop operating to avoid excessive clamping force causing deformation of the paper core tube.

[0045] Furthermore, the number of clamping components is multiple sets, and the multiple sets of clamping components are arranged at intervals along the length direction of the paper core tube. Each set of clamping components includes a corresponding first clamping member 431 and a second clamping member 432, and the structure is consistent with the aforementioned clamping components.

[0046] In this embodiment, the number of clamping components can be flexibly adjusted according to the length of the paper core tube. When the device is working, multiple sets of clamping components open and close synchronously through the linkage of the transmission structure 300, applying balanced clamping force from different positions of the paper core tube. By increasing the number of clamping components, this embodiment can accommodate longer paper core tubes, achieving flexible adaptation to paper core tubes of different lengths and expanding the applicability of the device.

[0047] See Figure 4 and Figure 5 Both the first clamping member 431 and the second clamping member 432 have a buffer layer 433 on the side facing the clamping area 450. The buffer layer 433 can be, for example, a rubber pad or a silicone sheet, and its thickness can be set according to the material hardness and other relevant requirements of the paper core tube. During clamping, when the first clamping member 431 and the second clamping member 432 approach the paper core tube, the buffer layer 433 first contacts the surface of the paper core tube, using its elastic deformation to absorb the clamping impact force, preventing direct contact between the metal clamping members and the paper core tube's outer surface from being indented or scratched. Simultaneously, the buffer layer 433 increases the friction between the clamping surface and the paper core tube, reducing relative sliding during clamping. When used with multiple clamping components, it can further improve the overall clamping reliability.

[0048] Furthermore, the paper core tube clamping device 10 for automatic core picking also includes, for example, a blocking structure 700 and a positioning sensor 800. The conveying mechanism 200 has, for example, an output end 210, which is, for example, the end of the paper core tube conveying path. The blocking structure 700 is disposed near the output end 210, for example, as a blocking plate perpendicular to the conveying roller 220, made of metal and fixed to the support frame 100 by a bracket. Its height is, for example, higher than the roller surface of the conveying roller 220, to block the paper core tube and prevent it from prematurely slipping off the output end 210 due to inertia or machine malfunction.

[0049] The positioning sensor 800 is disposed on the side of the blocking structure 700 facing the conveying mechanism 200. In this embodiment, the positioning sensor 800 can be, for example, a photoelectric sensor switch, with its sensing end horizontally facing the conveying surface of the conveying mechanism 200. The positioning sensor 800 is electrically connected to the controller. When the paper core tube is conveyed to the core-taking area (clamping area 450), the paper core tube blocks the detection light path of the photoelectric sensor switch. The positioning sensor 800 then sends a positioning signal to the controller. After receiving the signal, the controller immediately controls the conveying roller 220 to stop rotating, ensuring that the paper core tube accurately stops in the core-taking area. Subsequently, the clamping mechanism 400 is activated to perform the clamping action. By setting the blocking structure 700 and the positioning sensor 800, the reliability of the device can be further improved.

[0050] In summary, in a specific embodiment of this utility model, the working principle of the paper core tube clamping device 10 for automatic core picking is as follows: When the paper core tube output from the production line enters the conveying mechanism 200, multiple conveying rollers 220 rotate synchronously, conveying the paper core tube along a preset conveying path. When the paper core tube is about to reach the preset core-taking area, the positioning sensor 800 detects the paper core tube and immediately sends a positioning signal to the controller. The controller receives the signal and controls the conveying rollers 220 to stop rotating, ensuring that the paper core tube accurately stops in the core-taking area (clamping area 450). Subsequently, the controller sends a command to control the drive end of the clamping drive 440 to extend, driving the upper main frame 410 to move downward. The upper main frame 410 synchronously drives the first transmission connector 311 and the fourth transmission connector 321 to slide downward along the slide rail 610, ensuring smooth movement. The two drive the third transmission connector 313 and the sixth transmission connector 323 to rotate through the first transmission connector and the fourth transmission connector, respectively, thereby driving the second transmission connector 312 and the fifth transmission connector 322 to slide upward along the slide rail 610, causing the lower main frame 420 to rise synchronously. At this time, the second clamping member 432, located directly below the clearance gap, extends through the clearance gap between the conveying rollers 220 and moves synchronously in the opposite direction to the first clamping member 431 on the upper main frame 410, clamping the paper core tube from both the upper and lower sides. When the clamping sensor 500 on the side of the first clamping member 431 touches the paper core tube and sends a signal, the controller controls the clamping drive member 440 to stop moving, completing the positioning and fixing, and waiting for the external core removal equipment to perform the core removal operation. After the external core removal equipment completes the core removal operation, the controller instructs the clamping drive member 440 to drive the upper main frame 410 to reset upward, and drive the lower main frame 420 to move downward through the transmission structure 300. The second clamping member 432 retracts to directly below the clearance gap, and the first clamping member 431 and the second clamping member 432 release the paper core tube. Then, the core-removed paper core tube is transported to the subsequent transfer and collection area. Subsequently, each mechanism executes the next work cycle under the control of the controller.
