Technical Field
[0001] The utility model relates to the technical field of adhesive tape processing, in particular to a packaging adhesive tape rewinding machine. Background Art
[0002] In the tape production and processing industry, the tape rewinder is one of the indispensable equipment. It is mainly used to sort, cut and rewind the long strips of tape into standard rolls for easy storage, transportation and use. However, the traditional tape rewinder lacks a structure to limit the position of the tape during the tape rewinding process. The tape has problems such as deviation and wrinkles during transportation, resulting in a decrease in the rewinding quality and affecting subsequent use.
[0003] In order to solve the above problems, we propose a packaging tape rewinder, which can limit and guide the moving tape to prevent the tape from deviating. Utility Model Content
[0004] In order to overcome the shortcomings of existing tape rewinders that lack a structure for limiting the position of the tape, and that the tape is deflected and wrinkled during conveyance, the utility model provides a packaging tape rewinder that can limit and guide the moving tape to prevent the tape from deflecting.
[0005] A packaging tape rewinding machine comprises a mounting base, a mother roll drum is clamped on the mounting base, a guide roller is rotatably connected to the mounting base, a winding drum is clamped on the mounting base, a servo motor is fixedly connected to the mounting base, and also comprises a lower clamping ring, the lower clamping ring is fixedly connected to the output shaft of the servo motor, an upper clamping ring is rotatably connected to the lower clamping ring, the upper clamping ring and the lower clamping ring are sleeved on one end of the winding drum, a threaded rod is threadedly connected between the upper clamping ring and the lower clamping ring, a longitudinally symmetrical guide frame is slidably connected between the guide rollers, a bidirectional lead screw is rotatably connected to the mounting base, the bidirectional lead screw is threadedly connected to the guide frame, a drive motor is fixedly connected to the mounting base, and the output shaft of the drive motor is connected to the bidirectional lead screw.
[0006] Further description: a rotating handle is provided at the upper end of the threaded rod.
[0007] Further description, it also includes longitudinally symmetrical guide rails, which are fixedly connected to the mounting base, guide rods are slidably connected between the longitudinally symmetrical guide rails, cutting knives are slidably connected to the guide rods, positioning rods are slidably connected to the guide rails, and elastic parts are connected between the positioning rods and adjacent guide rails.
[0008] Further explanation: the cutting knife is provided with a push-pull ring.
[0009] To further explain, one end of the locking rod close to the guide rod is an arc structure, and both front ends of the guide rod are provided with locking grooves adapted to the locking rod.
[0010] Further description, it also includes a scraping plate, which is rotatably connected to the mounting frame, the scraping plate is in contact with the winding drum, and a longitudinally symmetrical torsion spring is connected between the scraping plate and the mounting frame.
[0011] The utility model has the following advantages: 1. The tape on the mother roll drum is drawn out, passes around three guide rollers in sequence, and is finally wound on the winding drum. The tape is located between the front and rear guide frames. When the tape moves to the right for transportation, the guide frames contact the front and rear sides of the tape, so the guide frames can guide and limit the tape to prevent the tape from deviating and affecting the rewinding quality.
[0012] 2.

DETAILED DESCRIPTION
[0024] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.
[0025] Embodiment 1: A packaging tape rewinding machine, such as Figure 1-Figure 6 As shown, it includes a mounting base 1, a mother roll drum 2, a guide roller 3, a winding drum 4, a servo motor 5, an upper clamping ring 6, a lower clamping ring 7, a threaded rod 8, a guide frame 9, a bidirectional screw rod 10 and a driving motor 11. The mother roll drum 2 is clamped on the lower left part of the mounting base 1, three evenly spaced guide rollers 3 are rotatably connected to the middle part of the mounting base 1, the winding drum 4 is clamped on the lower right part of the mounting base 1, the servo motor 5 is fixedly connected to the lower right part of the front side of the mounting base 1, the lower clamping ring 7 is fixedly connected to the output shaft of the servo motor 5, and the lower clamping ring 7 is fixedly connected to the output shaft of the servo motor 5. An upper clamping ring 6 is rotatably connected, and the upper clamping ring 6 and the lower clamping ring 7 are sleeved on the front end of the winding drum 4. A threaded rod 8 is threadedly connected between the upper clamping ring 6 and the right part of the lower clamping ring 7, and a rotating handle is provided at the upper end of the threaded rod 8. A front-to-back symmetrical guide frame 9 is slidably connected between the three guide rollers 3. A bidirectional lead screw 10 is rotatably connected to the middle and upper part of the mounting base 1, and the bidirectional lead screw 10 is threadedly connected to the guide frame 9. A driving motor 11 is fixedly connected to the middle and upper part of the front side of the mounting base 1, and the output shaft of the driving motor 11 is connected to the bidirectional lead screw 10.
[0026] When using the device, the take-up drum 4 is clamped with the output shaft of the servo motor 5 through the upper clamping ring 6 and the lower clamping ring 7. Then the staff draws out the tape on the parent roll drum 2, so that the tape passes around the three guide rollers 3 in sequence and is finally wound on the take-up drum 4. At this time, the tape is located between the front and rear guide frames 9. The bidirectional screw rod 10 is controlled by the driving motor 11 to rotate, which can drive the guide frames 9 to slide toward or away from each other, thereby adjusting the distance between the front and rear guide frames 9 so that the guide frames 9 contact the front and rear sides of the tape to adapt to tapes of different widths. After the guide frames 9 are adjusted, the staff controls the servo motor 11 to rotate. The machine 5 operates, and the servo motor 5 operates to drive the take-up drum 4 to rotate through the upper clamping ring 6 and the lower clamping ring 7. The take-up drum 4 rotates to reel up the tape. When the tape moves to the right for transportation, since the guide frame 9 contacts the front and rear sides of the tape, the guide frame 9 can guide and limit the tape to prevent the tape from deviating and affecting the rewinding quality. When the tape on the take-up drum 4 is reeled to a certain thickness, the staff can drive the threaded rod 8 to rotate through the turning handle. After the threaded rod 8 rotates, it moves upward and separates from the upper clamping ring 6 and the lower clamping ring 7. At this time, the upper clamping ring 6 can be rotated upward to open, so that the staff can remove the take-up drum 4 from the device.
[0027] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 7 and Figure 8 As shown, it also includes a guide rail 12, a guide rod 13, a cutting knife 14, a locking rod 15 and an elastic member 16. The lower right part of the mounting base 1 is fixedly connected to a front and rear symmetrical guide rail 12, a guide rod 13 is slidably connected between the front and rear guide rails 12, a cutting knife 14 is slidably connected to the guide rod 13, a push-pull ring is provided on the cutting knife 14, a locking rod 15 is slidably connected to the upper part of the guide rail 12, the end of the locking rod 15 close to the guide rod 13 is an arc structure, the front and rear parts of the guide rod 13 are provided with a slot adapted to the locking rod 15, and an elastic member 16 is connected between the locking rod 15 and the adjacent guide rail 12.
[0028] When the tape on the winding drum 4 is wound to a certain thickness, the staff controls the guide rod 13 to slide upward in the guide rail 12. After the guide rod 13 slides upward, it is locked by the locking rod 15. Then the staff drives the cutting knife 14 to slide on the guide rod 13 through the push-pull ring, and then cuts off the tail end of the tape on the winding drum 4, so that the tape on the parent roll drum 2 can be wound on the next winding drum 4. After the cutting is completed, the staff pushes the guide rod 13 to slide downward, thereby driving the cutting knife 14 to move downward and separate from the tape. Since the end of the locking rod 15 close to the guide rod 13 is an arc structure, and the guide rod 13 is provided with a locking groove adapted to the locking rod 15, under the action of the elastic member 16, the locking rod 15 can automatically lock or disengage when the guide rod 13 moves upward or downward.
[0029] like Figure 1 and Fig. 9 As shown, it also includes a scraper plate 17 and a torsion spring 18. The scraper plate 17 is rotatably connected to the lower right part of the mounting frame 1. The lower side of the scraper plate 17 is in contact with the winding drum 4. A torsion spring 18 is connected between the scraper plate 17 and the mounting frame 1 in a front-to-back symmetrical manner.
[0030] When the device is used, the scraping plate 17 contacts the take-up drum 4, and the tape wound on the take-up drum 4 will be scraped and pressed by the scraping plate 17 to avoid wrinkles on the tape. At the same time, under the action of the torsion spring 18, the scraping plate 17 will rotate following the winding thickness of the tape on the take-up drum 4, thereby maintaining a fit with the take-up drum 4 to ensure the scraping and pressing effect.
[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
