Abstract
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 alignment and adjustment mechanism. Background Technology
[0002] In the production of adhesive tape tubes, precise positioning and alignment are crucial to ensure the quality of the finished product and the efficiency of subsequent processing or packaging. Traditional adhesive tape tube positioning methods often rely on simple mechanical structures or manual operations, which are not only inefficient but also fail to guarantee high-precision positioning results. Furthermore, with the expansion of production scale and the increase in automation, the requirements for adhesive tape tube positioning mechanisms are becoming increasingly stringent.
[0003] While some existing positioning devices can achieve basic fixing and positioning functions, they often lack sufficient adaptability and flexibility when dealing with adhesive tape tubes of different sizes, shapes, or materials. For example, some devices may not be able to accurately handle minute changes in the diameter of the paper tube, or they may not be able to complete the positioning action quickly and accurately on high-speed production lines.
[0004] Therefore, we propose a tape-paper tube alignment and adjustment mechanism. Utility Model Content
[0005] The main objective of this application is to provide a tape-paper tube alignment and adjustment mechanism, which aims to solve the problems of low positioning accuracy, insufficient adaptability and flexibility of tape-paper tubes in the prior art.
[0006] To achieve the above objectives, this application provides a tape and paper tube alignment and adjustment mechanism, comprising: an installation frame, a tape and paper tube finished product pusher slidably disposed within the installation frame, and a tape and paper tube positioning mechanism fixedly disposed on a side wall of one side of the installation frame.
[0007] The tape paper tube positioning mechanism has at least one upper tape paper tube positioning plate and one lower tape paper tube positioning plate. The upper tape paper tube positioning plate and the lower tape paper tube positioning plate are respectively provided with inwardly recessed arc-shaped positioning grooves on their opposite sides for tightly fitting with the outer wall of the tape paper tube to achieve precise positioning of the tape paper tube. The two arc-shaped positioning grooves cooperate to form an adjustment space with an outer contour that approximates the currently processed paper tube. The adjustment space cooperates with the tape paper tube finished product pusher inside the mounting frame.
[0008] The adhesive tape paper tube finished product pusher includes: a pusher body, which is axially slidably disposed within the mounting frame; a central positioning shaft extending axially from one side of the pusher body toward the adjustment space; a paper tube clamping mechanism at one end of the central positioning shaft; and a tapered guide surface at the other end of the central positioning shaft; the tapered guide surface extends into the adjustment space, and its central axis coincides with the central axis of the adjustment space.
[0009] Preferably, the paper tube clamping mechanism includes: a pushing member, which is fixedly disposed on the side wall of the pushing member body facing the adjustment space, and a linear bushing is sleeved on the outer periphery of the central positioning shaft, a positioning ear plate is fixed on the linear bushing, the positioning ear plate is connected to the output end of the pushing member, so that it has the ability to reciprocate along the axis of the central positioning shaft, a claw mounting part is also sleeved on the outer periphery of the central positioning shaft, a plurality of clamping arms are arranged circumferentially on the outer periphery of the claw mounting part, the middle part of the clamping arm is hinged to the claw mounting part, and the clamping arm can swing around the hinge point between itself and the claw mounting part within a certain angle range, an arc-shaped guide part is provided at the end of the clamping arm near the linear bushing, a ball is installed in the arc-shaped guide part, a part of the ball protrudes out of the arc-shaped guide part and contacts the outer edge surface of the central positioning shaft, and a clamping finger is provided at the end of the clamping arm away from the linear bushing.
[0010] Preferably, the outer surface of the central positioning shaft that contacts the ball bearing is inclined.
[0011] Preferably, the gripper mounting portion is further provided with a torsion spring, one end of which is connected to the gripper mounting portion and the other end is connected to the gripping arm.
[0012] Preferably, a driving component is provided on the side of the main body of the pusher that is away from the adjustment space. The driving component is fixedly installed on the side wall of the other side of the mounting frame to provide power for pushing and positioning the paper tube.
[0013] Preferably, a synchronization mechanism is further provided between the driving component and the main body of the pushing component. The synchronization mechanism includes: a driver, which is disposed on the side wall of the main body of the pushing component away from the adjustment space. The output end of the driver extends into the driving cavity inside the main body of the pushing component and is rotatably connected to the input end of a belt transmission mechanism disposed in the driving cavity. The output end of the belt transmission mechanism is rotatably connected to a guide rod. The guide rod passes through the mounting frame and is connected to an external positioning mounting plate. A translation connecting plate is fixed on the positioning mounting plate. The driving component is fixed below the positioning mounting plate, and the output end of the driving component is connected to an adjusting screw. The adjusting screw is threadedly connected to the translation connecting plate.
[0014] Preferably, a sliding guide rail is provided within the mounting frame along its long axis, and the number of the sliding guide rails is at least one. A lead screw translation mechanism is provided between the sliding guide rails, and the lead screw translation mechanism is connected to the main body of the pusher.
[0015] Preferably, a drag chain is provided on the outside of the pusher body to provide power and control signal transmission for the movement of the pusher body.
[0016] Preferably, both the upper tape paper tube positioning plate and the lower tape paper tube positioning plate are connected to a lifting cylinder for adjusting the vertical position of the tape paper tube to ensure the stability and accuracy of the paper tube during the pushing process.
[0017] The beneficial effects of this utility model's technical solution are as follows:
[0018] When the finished tape tube is conveyed to the alignment and adjustment mechanism, it first comes into contact with the tapered guide surface at one end of the central positioning shaft. Due to the special shape of the tapered guide surface, it guides the tape tube gradually toward the central axis of the adjustment space, allowing the tape tube to achieve a certain degree of initial centering upon entering the adjustment space. As the tape tube continues to move forward, its outer wall will fit tightly against the arc-shaped positioning grooves on the upper and lower tape tube positioning plates. The adjustment space formed by these two arc-shaped positioning grooves has an outline similar to the currently processed paper tube, enabling further precise positioning and adjustment of the tape tube, ensuring that the tape tube is in the correct position during subsequent processing or packaging.
[0019] The paper tube clamping mechanism on the central positioning shaft reliably clamps the tape paper tube, preventing it from shifting or shaking during the alignment process. After the tape paper tube is aligned, the pusher body can slide along the mounting frame axially under the action of the drive device, pushing the aligned tape paper tube to the next process position, thus completing the entire alignment and conveying process.
[0020] When the tape tube needs to be clamped, the pusher receives a drive signal and begins to move, causing the positioning ear plate to move linearly under the limiting action of the linear bushing. As the positioning ear plate moves, the connected gripper mounting part also moves synchronously along the axis of the central positioning shaft. Since the clamping arm is hinged to the gripper mounting part, during the movement of the gripper mounting part, the clamping arm will gradually swing around the hinge point under the action of the tape tube, so that the ball bearings on the inner side of the clamping arm can tightly fit against the outer wall of the tape tube, while the clamping fingers on the outer side of the clamping arm will abut against the outer wall of the tape tube.

[0030] See Figures 1-3This utility model proposes a tape-paper tube alignment and adjustment mechanism, including: a mounting frame 100, a tape-paper tube finished product pusher 200 slidably disposed within the mounting frame 100, and a tape-paper tube positioning mechanism 300 fixed on a side wall of one side of the mounting frame 100; the tape-paper tube positioning mechanism 300 has at least one upper tape-paper tube positioning plate 301 and one lower tape-paper tube positioning plate 302, and the opposite sides of the upper tape-paper tube positioning plate 301 and the lower tape-paper tube positioning plate 302 are respectively provided with inwardly recessed arc-shaped positioning grooves 303, which are used to tightly fit with the outer wall of the tape-paper tube to achieve precise positioning of the tape-paper tube, and the two arc-shaped positioning grooves 303 cooperate to form an adjustment space with an outer contour approximately similar to the currently processed paper tube, and the adjustment space cooperates with the tape-paper tube finished product pusher 200 inside the mounting frame 100;
[0031] The adhesive tape paper tube finished product pusher 200 includes: a pusher body 201, which is axially slidably disposed within the mounting frame 100. A central positioning column 202 extends axially from one side of the pusher body 201 toward the adjustment space. A paper tube clamping mechanism 203 is provided at one end of the central positioning column 202, and a tapered guide surface 204 is provided at the other end of the central positioning column 202. The tapered guide surface 204 extends partially into the adjustment space, and its central axis coincides with the central axis of the adjustment space.
[0032] In this embodiment, when the finished tape tube is conveyed to the alignment and adjustment mechanism, it first comes into contact with the tapered guide surface 204 at one end of the central positioning shaft 202. Due to the special shape of the tapered guide surface 204, it can guide the tape tube to gradually move closer to the central axis of the adjustment space, so that the tape tube can initially achieve a certain degree of centering when entering the adjustment space. As the tape tube continues to move forward, its outer wall will fit tightly with the arc-shaped positioning grooves 303 on the upper tape tube positioning plate 301 and the lower tape tube positioning plate 302. The adjustment space formed by the cooperation of these two arc-shaped positioning grooves 303 has an outer contour that is similar to the currently processed paper tube, which can further accurately position and adjust the tape tube, ensuring that the tape tube is in the correct position during subsequent processing or packaging.
[0033] Meanwhile, the paper tube clamping mechanism 203 on the central positioning shaft 202 reliably clamps the tape paper tube, preventing it from shifting or shaking during the alignment process. After the tape paper tube is aligned, the pusher body 201 can slide along the axial direction of the mounting frame 100 under the action of the drive device, pushing the aligned tape paper tube to the next process position, thus completing the entire alignment and conveying process.
[0034] See Figures 4-5In one embodiment, the paper tube clamping mechanism 203 includes: a pusher 2031, which is fixedly disposed on the side wall of the pusher body 201 facing the adjustment space; a linear bushing 2032 is sleeved on the outer periphery of the central positioning shaft 202; a positioning ear plate 2033 is fixedly disposed on the linear bushing 2032; the positioning ear plate 2033 is connected to the output end of the pusher 2031, enabling it to reciprocate along the axial direction of the central positioning shaft 202; and a gripper mounting portion 2034 is also sleeved on the outer periphery of the central positioning shaft 202. A plurality of clamping arms 2035 are arranged circumferentially. The middle part of each clamping arm 2035 is hinged to the gripper mounting part 2034, and the clamping arm 2035 can swing around the hinge point between itself and the gripper mounting part 2034 within a certain angle range. An arc-shaped guide part 2036 is provided at the end of the clamping arm 2035 near the linear bushing 2032. A ball bearing 2037 is installed in the arc-shaped guide part 2036. A part of the ball bearing 2037 protrudes out of the arc-shaped guide part 2036 and contacts the outer edge surface of the center positioning column 202. A clamping finger 2038 is provided at the end of the clamping arm 2035 away from the linear bushing 2032.
[0035] In this embodiment, when the adhesive tape tube needs to be clamped, the pusher 2031 receives a drive signal and begins to move, causing the positioning ear plate 2033 to move linearly under the limiting action of the linear bushing 2032. As the positioning ear plate 2033 moves, the gripper mounting part 2034 connected to it also moves synchronously along the axis of the central positioning column 202. Since the clamping arm 2035 is hinged to the gripper mounting part 2034, during the movement of the gripper mounting part 2034, the clamping arm 2035 will gradually swing around the hinge point under the action of the adhesive tape tube, so that the ball bearing 2037 on the inner side of the clamping arm 2035 can tightly fit the outer wall of the adhesive tape tube, while the clamping fingers 2038 on the outer side of the clamping arm 2035 will abut against the outer wall of the adhesive tape tube.
[0036] Furthermore, the outer surface of the central positioning shaft 202 that contacts the ball bearing 2037 is inclined. Therefore, when the clamping arm 2035 swings, the ball bearing 2037 generates a component force under the action of the inclined surface, allowing the clamping finger 2038 to better conform to the outer wall of the adhesive tape tube, improving the stability and reliability of the clamping.
[0037] Specifically, the pushing component 2031 is a hydraulic push rod. The hydraulic push rod is connected to an external hydraulic system via an oil pipe. When clamping the tape tube, the external hydraulic system injects high-pressure oil into the hydraulic push rod, pushing the piston rod out and causing the positioning ear plate 2033 to move, thus achieving the clamping action. When the preset clamping position is reached, the external hydraulic system stops supplying oil and maintains stable pressure through a control valve to ensure the reliability of the clamping. When releasing the tape tube, the external hydraulic system discharges the oil from the hydraulic push rod through a control valve. The piston rod retracts under the action of a spring, causing the positioning ear plate 2033 to move in the opposite direction, thereby releasing the clamping arm 2035.
[0038] In one embodiment, a torsion spring is also provided on the gripper mounting portion 2034, with one end connected to the gripper mounting portion 2034 and the other end connected to the clamping arm 2035. When the clamping arm 2035 swings, the torsion spring stores elastic potential energy, thereby providing a certain clamping force to the clamping arm 2035, ensuring that the clamping arm 2035 can tightly adhere to the adhesive tape tube. Furthermore, a pressure sensor can be provided on the clamping arm 2035, which is electrically connected to the control system for real-time monitoring of the pressure during the clamping process. When the pressure reaches a preset suitable range, the control system controls the pusher 2031 to stop moving, at which point the clamping arm 2035 achieves stable and reliable clamping of the adhesive tape tube.
[0039] The torsion spring is not shown in the accompanying drawings.
[0040] In one embodiment, a drive member 400 is provided on the side of the pusher body 201 away from the adjustment space. The drive member 400 is fixedly mounted on the side wall of the other side of the mounting frame 100 to provide power for pushing and positioning the paper tube.
[0041] Furthermore, the driving component 400 is specifically an electric push rod. The electric push rod has advantages such as simple structure, convenient control, large driving force, and precise displacement control. When the paper tube needs to be pushed, the electric push rod starts working after receiving a signal from the control system. Its internal motor rotates, transmitting power to the pushing component body 201 through the push rod, causing the pushing component body 201 to move smoothly towards the adjustment space, thereby accurately pushing the tape paper tube to the designated position. When the preset pushing position is reached, the control system will control the electric push rod to stop working, ensuring the positioning accuracy of the paper tube.
[0042] In one embodiment, a drive member 400 is provided on the side of the pusher body 201 away from the adjustment space. The drive member 400 is fixedly mounted on the side wall of the other side of the mounting frame 100 to provide power for pushing and positioning the paper tube.
[0043] Further, the driving component 400 is specifically a hydraulic cylinder. The hydraulic cylinder is connected to an external hydraulic system via an oil pipe. When the paper tube needs to be pushed, the external hydraulic system injects high-pressure oil into the hydraulic cylinder, pushing the piston rod out, thereby causing the pushing component body 201 to move towards the adjustment space, accurately pushing the paper tube to the designated position. When the preset pushing position is reached, the external hydraulic system stops supplying oil through a control valve and maintains stable pressure to ensure the positioning accuracy of the paper tube. When the pushing component body 201 needs to be reset, the external hydraulic system changes the oil flow direction through a control valve, causing the piston rod to retract and driving the pushing component body 201 back to its initial position.
[0044] In one embodiment, a synchronization mechanism 500 is further provided between the driving member 400 and the pusher body 201. The synchronization mechanism 500 includes: a driver 501, which is disposed on the side wall of the pusher body 201 away from the adjustment space. The output end of the driver 501 extends into the driving cavity inside the pusher body 201 and is rotatably connected to the input end of a belt drive mechanism 502 disposed in the driving cavity. The output end of the belt drive mechanism 502 is rotatably connected to a guide rod 503. The guide rod 503 passes through the mounting frame 100 and is connected to an external positioning mounting plate 504. A translation connecting plate 505 is fixed on the positioning mounting plate 504. The driving member 400 is fixed below the positioning mounting plate 504, and the output end of the driving member 400 is connected to an adjusting screw 506. The adjusting screw 506 is threadedly connected to the translation connecting plate 505.
[0045] When the paper tube needs to be pushed, the external hydraulic system injects high-pressure oil into the hydraulic cylinder, pushing the piston rod out. Simultaneously, the driver 501 starts working, its output end rotating, transmitting power to the connecting adjusting screw 506 via the belt drive mechanism 502, causing the connecting adjusting screw 506 to rotate. Since the connecting adjusting screw 506 is threadedly connected to the translation connecting plate 505, and the translation connecting plate 505 is fixed to the positioning mounting plate 504, the rotation of the connecting adjusting screw 506 will cause the positioning mounting plate 504 to move smoothly along the direction of the translation screw 701. The translation screw 701, rotatably connected to the output end of the driver 400, will also rotate with the movement of the positioning mounting plate 504, thereby achieving precise guidance and positioning of the pushing component body 201.
[0046] See Figure 6In one embodiment, a sliding guide rail 600 is provided inside the mounting frame 100 along its long axis. There are at least two sliding guide rails 600. A lead screw translation mechanism 700 is provided between the two sliding guide rails 600. The lead screw translation mechanism 700 is connected to the pusher body 201.
[0047] The lead screw translation mechanism 700 includes a lead screw 701 and a lead screw nut 702 that cooperates with the lead screw 701. The lead screw 701 is arranged along the long axis of the mounting frame 100, and one end of the lead screw 701 passes through the pusher body 201 and is threadedly connected to the pusher body 201. The other end is connected to a drive motor 703 outside the mounting frame 100 via a coupling. When it is necessary to push the paper tube, the external drive device drives the lead screw 701 to rotate, and the lead screw nut 702 moves linearly along the lead screw 701, thereby driving the pusher body 201 to move smoothly in a linear motion along the sliding guide rail 600, realizing the precise pushing of the paper tube.
[0048] Furthermore, a drag chain 704 is provided on the outside of the pusher body 201 to provide power and control signal transmission for the movement of the pusher body 201. The drag chain 704 includes multiple links, each of which contains cables and air pipes for connecting external drive devices, controllers, and sensors and actuators on the pusher body 201.
[0049] In this embodiment, when the paper tube needs to be pushed, the external drive device sends a control signal to the motor or actuator on the pushing component body 201 via the cable chain 704, driving the lead screw 701 to rotate. The lead screw nut 702 moves linearly along the lead screw 701, thereby driving the pushing component body 201 to move smoothly in a linear motion along the sliding guide rail 600, achieving precise pushing of the paper tube. At the same time, the cable chain 704 also ensures that the pushing component body 201 remains connected to the cables and air pipes of external equipment during movement, avoiding the pushing operation being affected by the entanglement of cables or air pipes.
[0050] In one embodiment, both the upper tape tube positioning plate 301 and the lower tape tube positioning plate 302 are connected to a lifting cylinder 800, which is used to adjust the vertical position of the tape tube to ensure the stability and accuracy of the paper tube during the pushing process.
[0051] In this embodiment, when paper tubes of different heights need to be pushed, the lifting cylinder 800 can adjust the distance between the upper tape paper tube positioning plate 301 and the lower tape paper tube positioning plate 302 according to the height of the paper tube. Specifically, when encountering a taller paper tube, the lifting cylinder 800 will raise the upper tape paper tube positioning plate 301 to increase the distance between it and the lower tape paper tube positioning plate 302 to accommodate the height of the paper tube; conversely, when encountering a shorter paper tube, the lifting cylinder 800 will lower the upper tape paper tube positioning plate 301 to decrease the distance between it and the lower tape paper tube positioning plate 302.
