Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, specifically a biaxial tape rewinding machine. Background Technology

[0002] Tape rewinding machines are common equipment in daily production, mainly used to rewind large rolls of material into smaller rolls of a specified length. The most basic requirement is that the material retains its original properties after rewinding, without wrinkles or bubbles. Tape rewinding machines are widely used in packaging, printing, electronics, automotive, and many other fields.

[0003] Existing tape rewinding machines have some problems when processing backed paper tape products. After being wound to the appropriate length and cut, the original tape roll is in a slack state. When the backed paper tape needs to be rewound onto the winding shaft, the original tape roll is difficult to pull because the backed paper tape lacks adhesion during winding. The rewound tape cannot withstand the winding tension, resulting in inching failure, affecting the normal winding of the tape, and reducing the efficiency of the rewinding machine. In addition, when rewinding backed paper tape after cutting, a robotic arm is usually used to grip the rewound tape roll tightly and pull it out from one end of the winding shaft. Since the inside of the rewound tape roll is supported by a hollow paper tube, when the outer surface of the tape roll is subjected to a large external force during extraction, it is easy to cause deformation of the tape roll. Utility Model Content

[0004] The purpose of this invention is to provide a biaxial tape rewinding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biaxial tape rewinding machine, comprising a frame, with notches on both sides of the back of the frame, a common unwinding shaft inside the two notches, a tension roller on the top of the frame, slides in the middle of both side walls of the frame, a take-up shaft inside the slides, a baffle at the bottom of the inner side of the slides, a pneumatic clamping roller below the take-up shaft, a second cylinder installed in the middle of both inner walls of the frame, and two first cylinders installed at the bottom of the front of the frame;

[0006] The tops of the two first cylinders are provided with a semi-cylinder. A drive motor is provided in the middle of the outer wall of one side of the frame. A first gear is installed at the output end of the drive motor. A second gear meshes with the outer wall of the first gear. A vertical plate is provided on one side of the frame. A groove is opened at the end of the slide. A cutting mechanism is provided at the top of the winding shaft.

[0007] Preferably, both ends of the unwinding shaft and the rewinding shaft are provided with sleeves, and a limit plate is fixedly connected to one side wall of the sleeve at both ends of the unwinding shaft. The unwinding shaft is rotatably connected to the notch through the sleeve.

[0008] Preferably, the sleeve on one end of the take-up shaft is fixedly connected to the second gear, and the take-up shaft is rotatably connected to the slide rail through the sleeve.

[0009] Preferably, a linear guide rail is provided at the bottom of one side of the frame, the vertical plate is slidably connected to the frame through the linear guide rail, and a groove is provided at the top of the vertical plate.

[0010] Preferably, a third cylinder is provided inside the inner wall of the frame, the output end of the third cylinder is fixedly connected to the bottom end of the baffle, the baffle is movably embedded in the slide rail through the third cylinder, and the baffle is slidably connected to the sleeve.

[0011] Preferably, the top and both ends of the semi-cylinder are provided with openings.

[0012] Preferably, the horizontal shaft on the inner side of the pneumatic clamping roller is fixedly connected to the top end of the output end of the second cylinder, and the pneumatic clamping roller is rotatably connected to the horizontal shaft passing through its inner side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This dual-shaft tape rewinding machine, through the installation of a second cylinder and a pneumatic clamping roller, can activate the second cylinder when the take-up shaft rewinds the cut end of the tape roll containing the backing paper. This causes the second cylinder to push the pneumatic clamping roller upward, allowing it to press the cut end of the tape roll tightly against the outer surface of the take-up shaft. When the take-up shaft rotates, the tape roll is subjected to the inching effect generated by the take-up shaft, thereby enabling the cut tape roll containing the backing paper to be rewound onto the take-up shaft, which helps to improve the winding efficiency of the rewinding machine.

[0015] 2. This biaxial tape rewinding machine, through the setting of a first cylinder and a semi-cylinder, allows the bottom of the outer wall of the rewound tape roll to be supported by the semi-cylinder when it is unloaded from the take-up shaft. It also changes the method of pulling the tape roll out from one end of the take-up shaft to pulling the take-up shaft out from one end of the tape roll, so that the tape roll remains stationary while the take-up shaft moves. This reduces the external force on the rewound tape roll during unloading, thereby reducing the probability of deformation of the tape roll during unloading. Attached Figure Description

[0024] like Figures 1 to 4As shown, this embodiment of the biaxial tape rewinding machine includes a frame 1. Notches 3 are provided on both sides of the back of the frame 1, and the notches 3 are angled downwards along the side walls of the frame 1, allowing the cylinder to rotate smoothly within the notches 3. A unwinding shaft 2 is provided inside both notches 3. The unwinding shaft 2 supports the tape roll for unwinding and rewinding. Tensioning rollers 21 are provided at the top of the frame 1. Two tensioning rollers 21 are provided to keep the cut end of the tape roll close to the take-up roller for rewinding. Slides 11 are provided in the middle of both side walls of the frame 1. The slides 11 allow the sleeve 18 to roll on the frame 1, so that the take-up shaft 17 can drive the rewound tape roll towards the semi-cylinder 14. The take-up shaft 17 is located inside the slides 11, and a baffle 10 is provided at the bottom of the inner side of the slides 11. The function of plate 10 is to keep the sleeves 18 at both ends of the take-up shaft 17 at the end of the slide 11, and at the same time, to make the second gear 7 at one end of the take-up shaft 17 mesh with the first gear 6, thereby ensuring the rotation of the take-up shaft 17. A pneumatic clamping roller 15 is provided below the take-up shaft 17. The pneumatic clamping roller 15 is composed of a horizontal shaft that passes through the roller and an external roller that can rotate freely, so that the pneumatic clamping roller 15 can reduce the interference caused to the rotation of the take-up shaft 17. A second cylinder 16 is installed in the middle of the inner wall on both sides of the frame 1. The function of the second cylinder 16 is to push the pneumatic clamping roller 15 so that the pneumatic clamping roller 15 presses the cut tape tightly to the bottom of the take-up shaft 17. Two first cylinders 13 are installed at the bottom of the front of the frame 1. The function of the first cylinder 13 is to push the semi-cylinder 14 to rise and fall, so that the semi-cylinder 14 can rise to the bottom of the rewinding tape roll and support the bottom of the tape roll.

[0025] The tops of the two first cylinders 13 are jointly provided with a semi-cylinder 14, which supports the rewound tape roll. A drive motor 5 is located in the middle of the outer wall of one side of the frame 1. The drive motor 5 drives the first gear 6 to rotate, thereby providing power for the rotation of the second gear 7. The output end of the drive motor 5 is equipped with the first gear 6, and the outer wall of the first gear 6 meshes with the second gear 7. The rotation of the second gear 7 provides power for the rotation of the sleeve 18 on the take-up shaft 17, thereby realizing the rotation of the take-up shaft 17. One side of the frame 1 is provided with The vertical plate 9 provides temporary support for the pulled-out take-up shaft 17, allowing it to be reset later. The slide 11 has a groove 12 at its end, which allows the take-up shaft 17 to stop at the end of the slide 11 after rolling along it, waiting for the semi-cylinder 14 to rise and support it. The top of the take-up shaft 17 is equipped with a cutting mechanism 19, which consists of a guide rail and a cutting blade. Its function is to cut the tape roll to a set length to achieve tape rewinding.

[0026] Specifically, sleeves 18 are provided at both ends of the unwinding shaft 2 and the take-up shaft 17. Limiting discs 4 are fixedly connected to one side wall of the sleeves 18 at both ends of the unwinding shaft 2. The unwinding shaft 2 is rotatably connected to the notch 3 through the sleeves 18. The function of the sleeves 18 is to enable the unwinding shaft 2 and the take-up shaft 17 to rotate in the corresponding positions, thereby realizing the unwinding and rewinding of the tape.

[0027] Furthermore, the sleeve 18 on one end of the take-up shaft 17 is fixedly connected to the second gear 7. The take-up shaft 17 is tumbledly connected to the slide 11 through the sleeve 18. After the second gear 7 is meshed and rotated by the first gear 6, it can drive the take-up shaft 17 to rotate at the end of the slide 11, thereby realizing the rewinding of the tape.

[0028] Furthermore, a linear guide rail 8 is provided at the bottom of one side of the frame 1, and the vertical plate 9 is slidably connected to the frame 1 through the linear guide rail 8. A groove is provided at the top of the vertical plate 9. The function of the linear guide rail 8 is to enable the vertical plate 9 to send the rewind shaft 17 back to a position close to its original position along a predetermined route within a set time period after supporting the pulled-out rewind shaft 17, so that the rewind shaft 17 can be reset subsequently.

[0029] Furthermore, a third cylinder 20 is provided inside the inner wall of the frame 1. The output end of the third cylinder 20 is fixedly connected to the bottom end of the baffle 10. The baffle 10 is movably embedded in the slide rail 11 through the third cylinder 20. The baffle 10 is slidably connected to the sleeve 18. The function of the third cylinder 20 is to drive the baffle 10 to move up and down along the slide rail 11, thereby realizing the separation of the baffle 10 and the sleeve 18.

[0030] Furthermore, the top and both ends of the semi-cylinder 14 are provided with openings, so that the semi-cylinder 14, which is pushed upward by the first cylinder 13, can directly support the tape roll from the bottom of the rewinding tape roll, thereby facilitating the support of the tape roll, reducing the external force on the tape roll when it is unloaded, and thus reducing the probability of the tape roll deforming when it is unloaded.

[0031] Furthermore, the horizontal shaft inside the pneumatic clamping roller 15 is fixedly connected to the top end of the output end of the second cylinder 16, and the pneumatic clamping roller 15 is rotatably connected to the horizontal shaft passing through its inner side, so that the pneumatic clamping roller 15 can rotate synchronously after the winding shaft 17 rotates, so that the end of the tape containing the bottom paper can be wound up along the outer wall of the winding roller more quickly, thereby facilitating the normal winding of the tape roll containing the bottom paper.

[0032] The usage method of this embodiment is as follows: When using this biaxial tape rewinding machine, first connect the machine to the external power supply, then place the tape roll on the frame 1 through the unwinding shaft 2, then pass the tape end of the roll between the two tension rollers 21 and attach it to the bottom of the take-up roller, then start the third cylinder 20. At this time, the third cylinder 20 will push the pneumatic clamping roller 15 to rise until the pneumatic clamping roller 15 presses the tape containing the backing paper against the bottom of the take-up shaft 17. Then, the drive motor 5 can be started. At this time, the drive motor 5 will drive the first gear 6 to rotate, so that the first gear 6 meshes with the second gear 7 to rotate, so that the second gear 7 drives the sleeve 18 to rotate within the range limited by the baffle 10 inside the slide 11. At this time, the take-up shaft 17 begins to rewind the tape roll. After reaching the appropriate length, the cutting mechanism 19 cuts the tape roll. At this time, the sleeve 18 on the take-up shaft 17, not obstructed by the baffle 10, slides into the groove 12 along the sloping slide 11. Simultaneously, the rewound tape roll on the take-up shaft 17 slides towards the semi-cylinder 14. When the tape roll stops above the semi-cylinder 14 after passing through the sleeve 18, the first cylinder 13 is activated, driving the semi-cylinder 14 to rise and support the rewound tape roll until the sleeve 18 on the take-up shaft 17 is raised above the groove 12. Then, the take-up shaft 17 can be pulled out from the end of the tape roll along the direction of the second gear 7 and placed in the groove of the vertical plate 9. Then, the take-up shaft 17 will move to a position close to its original position as the vertical plate 9 slides along the linear guide rail 8, so that the take-up shaft 17 can be reset later.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
