[0001] This utility model relates to the field of slitting circular blade technology, specifically a slitting circular blade for a rewinding machine that can be finely adjusted online. Background Technology

[0002] In the production processes of industries such as packaging, printing, and papermaking, rewinding machines are key equipment for realizing the winding and slitting of materials. As the core execution component of the rewinding machine, the slitting circular blade directly affects the dimensional consistency and quality of the final product.

[0003] A patent document with publication number CN210732566U discloses a slitting circular blade for a rewinding machine, including a mounting post. A locking post is fixedly connected to the bottom of the mounting post. The locking post has four adjustment cavities inside. A first limiting spring is movably connected inside the top adjustment cavity. A first limiting rod extending outside the adjustment cavity is fixedly connected to the outside of the first limiting spring. This slitting circular blade for the rewinding machine is fixed to the blade holder output shaft of the rewinding machine by the mounting post via the locking post. The circular blade is locked to the outside of the locking post. At this time, the first limiting rod and the second limiting rod are locked to both sides of the circular blade under the elastic force provided by the first and second limiting springs. Furthermore, an anti-slip layer adheres to the circular blade and prevents it from sliding, thus effectively solving the problems of difficulty in ensuring installation stability and ease of installation of rewinding machine blades during long-term use.

[0004] The above-mentioned solutions and most existing technologies lack a design that allows for precise online fine-tuning of the slitting circular blade. Factors such as changes in material thickness and blade wear can cause the slitting position to shift. If the position of the circular blade cannot be finely adjusted without stopping the rewinding machine, the machine must be stopped, the blade disassembled, and repositioned, which may consume a lot of production time.

[0005] Therefore, this utility model proposes an online fine-tunable slitting circular knife for a rewinding machine to solve the above problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0021] Example 1: Please refer to Figures 1 to 2 A rewinder with an online fine-adjustable slitting circular blade includes a rewinder body 1, a circular blade 2, and a main shaft 3. The main shaft 3 is mounted on the rewinder body 1, and the material to be cut 4 is placed on the main shaft 3. The rewinder body 1 is provided with an adjustment component 5, a snap-fit ​​component 6, and a securing component 7. The adjustment component 5 is located on the rewinder body 1, the snap-fit ​​component 6 is located on both sides of the adjustment component 5, and the securing component 7 is located on the snap-fit ​​component 6.

[0022] The first fixed shaft 501 and the second fixed shaft 502 in the adjustment assembly 5 are installed on the rewinder body 1. The first fixed shaft 501 is evenly provided with mounting grooves 503. The first movable sleeve 504 is sleeved in the mounting groove 503 and is located inside the circular blade 2.

[0023] The second fixed shaft 502 in the adjustment assembly 5 is provided with a second mounting groove 505. A second movable sleeve 506 is installed and sleeved in the second mounting groove 504. The second mounting groove 505 and the mounting groove 503 are evenly provided with scales. The second movable sleeve 506 and the first movable sleeve 504 are fixedly connected by a connecting rod 507.

[0024] When in use, start the main body 1 of the rewinder. The main shaft 3 drives the material to be cut 4 to rotate. The circular blade 2 cuts the material. When it is necessary to adjust the position of the circular blade 2 to adapt to different cutting requirements, the adjustment component 5 can be used to push the first moving sleeve 504 to move along the mounting groove 503, thereby driving the circular blade 2 to move synchronously. At the same time, when the first moving sleeve 504 moves, it will drive the second moving sleeve 506 to move synchronously along the second mounting groove 505 through the connecting rod 507, so as to avoid the circular blade 2 from deviating. During the process, the scale on the mounting groove 503 and the second mounting groove 505 can be observed to intuitively control the adjustment amount of the circular blade 2. After ensuring that it is adjusted to the appropriate position, the subsequent cutting operation can be carried out to meet the initial position adjustment requirements.

[0025] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The first snap-fit ​​protrusion 601 in the snap-fit ​​assembly 6 is fixedly disposed at both ends of the first movable sleeve 504. The first snap-fit ​​protrusion 601 is slidably snapped into the snap-fit ​​groove 602. The snap-fit ​​groove 602 is disposed at both ends of the mounting groove 503. A pointer is provided on the first snap-fit ​​protrusion 601.

[0026] The second snap-fit ​​protrusion 603 in the snap-fit ​​assembly 6 is fixedly disposed at both ends of the second movable sleeve 506. The second snap-fit ​​protrusion 603 is slidably snapped into the second snap-fit ​​groove 604. The second snap-fit ​​groove 604 is disposed at both ends of the second mounting groove 505. The second snap-fit ​​protrusion 603 is provided with a pointer.

[0027] During use, as the first movable sleeve 504 and the second movable sleeve 506 are moved by adjusting component 5, the locking component 6 plays a guiding and precision-aiding role. The first locking protrusions 601 at both ends of the first movable sleeve 504 slide along the locking grooves 602 at both ends of the mounting groove 503, and the second locking protrusions 603 at both ends of the second movable sleeve 506 slide along the second locking grooves 604 at both ends of the second mounting groove 505. The sliding cooperation between the protrusions and the grooves provides stable guidance for the movement of the sleeves, preventing lateral deviation of the sleeves during movement and ensuring the accurate movement direction of the circular blade 2. At the same time, the pointers on the first locking protrusions 601 and the second locking protrusions 603 move synchronously with the protrusions, pointing to the scales on the mounting groove 503 and the second mounting groove 505. The operator can accurately read the adjustment value through the pointers, further improving the fine-tuning accuracy of the circular blade 2, avoiding adjustment errors caused by visual deviation, and ensuring accurate cutting position.

[0028] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The first fixing pin 701 in the fastening assembly 7 threadedly connects the first movable sleeve 504 to the mounting groove 503, and the second fixing pin 702 in the fastening assembly 7 threadedly connects the second movable sleeve 506 to the second mounting groove 505.

[0029] In use, after adjusting the circular blade 2 to the target position using the adjusting component 5 and the snap-fit ​​component 6, the sleeve position is fixed using the securing component 7. For the first movable sleeve 504, the first fixing pin 701 in the securing component 7 is aligned with the corresponding threaded hole on the first movable sleeve 504 and the mounting groove 503. The threaded holes are set according to the scale intervals. When the scale is aligned, the threaded holes will be aligned accordingly for easy fixing. Rotate the first fixing pin 701 to thread the first movable sleeve 504 onto the mounting groove 503, thereby achieving a secure fixation of the first movable sleeve 504. Similarly, for the second movable sleeve 506, the second fixing pin 702 is aligned with the threaded hole on the second movable sleeve 506 and the second mounting groove 505. Similarly, the threaded holes are set according to the scale, and can be aligned and fixed. After fixing, the rewinding machine body 1 is started for slitting operation. At this time, the positions of the first movable sleeve 504 and the second movable sleeve 506 are stable and will not loosen due to the force of material slitting.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
