[0043] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0044] Example 1

[0045] The present invention provides an automatic guiding rotation correction belt, such as Figures 1-4As shown, it comprises an outer shell 1 and a core member 2. The outer shell 1 has a cylindrical sleeve portion 11. The core member 2 has a shaft portion 21. The core member 2 is a rotating member whose center of gravity is offset from the rotation axis of the shaft portion 21. The shaft portion 21 is mounted in a circumferentially rotatable manner within the sleeve portion 11. The core member 2 is provided with a tape discharge nozzle 22. The tape discharge nozzle 22 has a nozzle tip 221 that acts on the surface to be corrected when scoring the tape. The core member 2 has a tape discharge side and a tape collection side on either side of the nozzle tip 221, and the center of gravity of the core member 2 is located on the tape discharge side.

[0046] The present invention provides an automatically guided rotating correction tape. The core member 2 can automatically adjust the nozzle tip 221 of the product by the action of gravity. The product can realize 360-degree automatic rotation, so that the nozzle tip 221 is not affected by factors such as the use angle, gripping method and use technique, and can always automatically find a horizontal position to fit the paper surface and wait for the correction surface, thereby bringing a better experience and fun when using it, and avoiding waste caused by improper use of the product.

[0047] As a preferred embodiment, refer to Figure 2 As shown, a counterweight 3 is provided on the core member 2, and the counterweight 3 is located at a position on the core member 2 that deviates from the rotation axis of the cylindrical shaft portion 21. The counterweight 3 can be an iron block.

[0048] Furthermore, the core member 2 includes a replacement core member 41 and a movable sleeve 42. The replacement core member 41 is detachably mounted on the movable sleeve 42. The movable sleeve 42 and the sleeve portion 11 are detachably rotatably connected together. The counterweight 3 is arranged on the movable sleeve 42.

[0049] In this embodiment, the movable sleeve 42 is provided with a mounting recess 421, the shape and size of which match the core replacement 41. The core replacement 41 and the movable sleeve 42 are tightly fitted and coaxially sleeved together to form the core member 2. The center of gravity of the counterweight 3 is offset from the axis of the core member 2 and is located on the outlet side of the nozzle tip 221. The outlet nozzle 22 is located at one axial end of the barrel shaft portion 21 (i.e., the core member 2), with the end where the nozzle 22 is located as the front end. The center of gravity of the counterweight 3 corresponds to the middle and rear ends of the core member 2, facilitating the rapid self-rotation of the core member 2.

[0050] The cross section of the replacement core 41 (perpendicular to the axis of the replacement core 41 ) is square, which prevents the replacement core 41 from rotating in the circumferential direction after being installed in the movable sleeve 42 .

[0051] The cylindrical shaft portion 21 has a first rotating fitting portion 211, and the cylindrical sleeve portion 11 has a second rotating fitting portion 111 that forms a circumferential rotational fit with the first rotating fitting portion 211. The first rotating fitting portion 211 is a ball, and the second rotating fitting portion 111 is a circular guide step. The ball rolls on the circular guide step to achieve rotational fit between the cylindrical shaft portion 21 and the cylindrical sleeve portion 11.

[0052] The outer shell 1 includes a barrel sleeve 11, a nozzle cover 12 and a tail cover 13. A belt outlet 112 is provided at one axial end of the barrel sleeve 11, and a belt outlet nozzle 22 extends from the belt outlet 112 to facilitate the belt stripping operation. The tail cover 13 is threadedly connected to the barrel sleeve 11, and the tail cover 13 limits the belt core member 2 to the inside of the barrel sleeve 11 to prevent the belt core member 2 (especially the replacement core member 41) from axial movement. The nozzle cover 12 is assembled with the barrel sleeve 11 through the cooperation of the retaining ring and the retaining groove, which protects the belt outlet nozzle 22. When the replacement core member 41 is to be replaced, the replacement operation can be achieved by simply pulling the replacement core member 41 out from the movable sleeve 42 along its axial direction.

[0053] It should be noted that, in the present invention, (1) the replacement core 41 is a conventional correction tape replacement core, including a correction tape body, a tape delivery wheel, a tape take-up wheel and other components, so as to realize the corresponding tape delivery and take-up functions. (2) The tape delivery nozzle 22 is a conventional correction tape delivery nozzle, so as to realize the tape stripping function, which will not be described in detail here. (3) The rotational matching structure between the barrel sleeve portion 11 and the barrel shaft portion 21 is not limited to the above-mentioned guide protrusion and guide protrusion (i.e., ball and circular guide step) matching method, and the guide protrusion and guide groove matching method can also be adopted to realize the circumferential rotation between the barrel sleeve portion 11 and the barrel shaft portion 21.

[0054] When the tape is used, the hand is held on the sleeve part 11. Due to the action of the counterweight block 3, the core piece 2 can automatically guide the core piece 2 (i.e. the tape outlet nozzle 22) to rotate to achieve the rebalancing of the center of gravity of the core piece 2, and finally automatically find the horizontal position to fit the paper surface and wait for the correction surface.

[0055] Example 2

[0056] The present invention provides an automatic guiding rotation correction belt, such as Figure 5 and Figure 6 As shown, it comprises an outer shell 1 and a core member 2. The outer shell 1 has a cylindrical sleeve portion 11. The core member 2 has a shaft portion 21. The core member 2 is a rotating member whose center of gravity is offset from the rotation axis of the shaft portion 21. The shaft portion 21 is mounted within the sleeve portion 11 in a circumferentially rotatable manner. The core member 2 is provided with a tape discharge nozzle 22. The tape discharge nozzle 22 has a nozzle tip 221 that acts on the surface to be corrected when the tape is scratched. The core member 2 has a tape discharge side and a tape collection side on either side of the nozzle tip 221, and the center of gravity of the core member 2 is located on the tape discharge side.

[0057] In a preferred embodiment, the core member 2 includes a replacement core member 41 having an eccentric portion 23. The eccentric portion 23 is an eccentric structure designed to be offset from the rotational axis of the cylindrical shaft portion 21. The cylindrical shaft portion 21 is rod-shaped, and a correction core is disposed within the eccentric portion 23. The eccentric portion 23 is located at one axial end of the cylindrical shaft portion 21.

[0058] The cylindrical shaft portion 21 has a first rotating fitting portion 211, and the cylindrical sleeve portion 11 has a second rotating fitting portion 111 that forms a circumferential rotating fit with the first rotating fitting portion 211. The first rotating fitting portion 211 is a boss (a type of guide boss) circumferentially arranged along the inner side wall of the cylindrical shaft portion 21, and the second fitting portion 111 is an elastic hook (a type of guide boss). The elastic hook is limited on the boss, which can realize the rotational fit of the cylindrical shaft portion 21 along the cylindrical sleeve portion 11.

[0059] The outer shell 1 includes a sleeve portion 11 and a limiting cap (not shown in the figure). An axial end of the sleeve portion 11 is provided with a belt outlet 112, and a belt outlet nozzle 22 extends from the belt outlet 112. The limiting cap is assembled on the front end of the sleeve portion 11 through the cooperation of the ridges and the grooves, and the rear end edge of the limiting cap corresponds to the elastic hook, thereby limiting the elastic hook from being dislocated at will and preventing the core member 2 (especially the replacement core member 41) from axial movement. To replace the core member 2, it is only necessary to loosen the limiting cap (usually a plastic member with a certain elasticity), and then forcibly pull out the replacement core member 41 from the front end to the rear end along the sleeve portion 11, so that the elastic hook is disengaged and the replacement core member 41 can be replaced.

[0060] Example 3

[0061] The main difference between this embodiment and embodiment 2 is that the eccentric design part of embodiment 2 is replaced by a counterweight block.

[0062] like Figure 7 As shown, the core member 2 includes a replacement core member 41 , on which a counterweight block 3 is provided. The counterweight block 3 is located at a position on the core member 2 that deviates from the rotation axis of the cylindrical shaft portion 21 .

[0063] The tape outlet nozzle 22 is arranged at one axial end of the cylindrical shaft portion 21 (i.e., the tape core member 2), with the end where the tape outlet nozzle 22 is located as the front end, and the counterweight block 3 is arranged at the rear end of the cylindrical shaft portion 21.

[0064] Example 4

[0065] The main difference between this embodiment and embodiment 2 is that: Figures 8-10 As shown, the refill 41 has not only the eccentric design portion 23 but also a counterweight 3. In addition, the rotational fit structure between the sleeve portion 11 and the shaft portion 21 is different.

[0066] The core member 2 is further provided with a counterweight 3 , which is located at a position on the core member 2 that is offset from the rotation axis of the cylindrical shaft portion 21 .

[0067] The tape outlet nozzle 22 is arranged at one axial end of the cylindrical shaft portion 21 (i.e., the tape core member 2), with the end where the tape outlet nozzle 22 is located as the front end, and the counterweight block 3 is arranged at the rear end of the cylindrical shaft portion 21.

[0068] The sleeve portion 11 has a second rotatable engagement portion 111 formed along its circumferential direction. This second rotatable engagement portion 111 is a groove (a type of guide groove). The shaft portion 21 has a first rotatable engagement portion 211 formed at a position corresponding to the groove. This first rotatable engagement portion 211 is a guide groove. The correction tape is also equipped with an elastic locking ring 5. The elastic locking ring 5 is restrained in the groove, and then the elastic locking ring 5 (or a portion thereof) is further restrained in the guide groove. Therefore, the elastic locking ring 5 acts as a guide protrusion. The elastic locking ring 5 cooperates with the guide groove to achieve circumferential rotation between the sleeve portion 11 and the shaft portion 21. When the refill 41 needs to be replaced, the elastic locking ring 5 must first be disengaged from the guide groove.

[0069] Example 5

[0070] The main differences between this embodiment and embodiment 2 are:

[0071] like Figures 11-13 As shown, the core member 2 includes a core replacement member 41 and a movable sleeve 42. The core replacement member 41 has an eccentric design portion 23, which is an eccentric structure designed to be offset from the rotation axis of the cylindrical shaft portion 21. The core replacement member 41 is detachably mounted on the movable sleeve 42, and the movable sleeve 42 and the cylindrical sleeve portion 11 are detachably connected to each other. In addition, the core member 2 is also provided with a counterweight block 3, which is located at a position on the core member 2 that is offset from the rotation axis of the cylindrical shaft portion 21. The counterweight block 3 is mounted on the movable sleeve 42.

[0072] In this embodiment, the movable sleeve 42 is provided with a mounting recess, the shape and size of which match the core replacement 41. The core replacement 41 is provided with an elastic hook 411, and the movable sleeve 42 is provided with a clamping platform 422 at the position corresponding to the elastic hook 411. The elastic hook 411 is hooked onto the clamping platform 422, and then the core replacement 41 and the movable sleeve 42 are sleeved together to form the core member 2. The center of gravity of the counterweight block 3 is offset from the axis of the core member 2, and the center of gravity of the eccentric design portion 23 is located on the outlet side of the nozzle tip 221. The outlet nozzle 22 is provided at one axial end of the barrel shaft portion 21 (i.e., the core member 2), with the end where the outlet nozzle 22 is located as the front end and the eccentric design portion 23 provided at the rear end of the barrel shaft portion 21.

[0073] The cross section of the core replacement member 41 (perpendicular to the axis of the core replacement member 41 ) is in an I-shape, which prevents the core replacement member 41 from rotating in the circumferential direction after being installed in the movable sleeve 42 .

[0074] The movable sleeve 42 has a first rotation fitting part 211, the sleeve part 11 has a second rotation fitting part 111 which forms a circumferential rotation fitting with the first rotation fitting part 211, the first rotation fitting part 211 is a guide groove, the second rotation fitting part 111 is a guide convex, the first rotation fitting part 211 and the second rotation fitting part 111 are respectively arranged along the circumferential direction of the cylinder shaft part 21, the guide convex is limited to slide in the guide groove, and the circumferential rotation fitting of the cylinder shaft part 21 and the sleeve part 11 is realized.

[0075] The shell 1 comprises the sleeve part 11 and the limiting cap 14. The sleeve part 11 is provided with a belt outlet 112 at one axial end, and the belt outlet 22 extends from the belt outlet 112. The limiting cap 14 is assembled on the front end of the sleeve part 11 through the cooperation of the convex strip and the groove, so as to prevent the axial movement of the belt core 2. When the belt core 2 needs to be replaced, the limiting cap 14 (usually a plastic part with a certain elasticity) is loosened, and then the replacement core 41 is pulled out from the front end to the rear end of the sleeve part 11 with force, the elastic clasp is released, and the replacement core 41 can be replaced.

[0076] Embodiment 6

[0077] The difference between the embodiment and the embodiment 2 is that the belt core is a non-replaceable replacement core, and the rotation fitting structure of the sleeve part and the cylinder shaft part.

[0078] As shown in Figure 14 The cylinder shaft part 21 is provided with a convex ring 212 along the circumferential direction thereof, and the inner circumferential wall of the sleeve part 11 is a circumferential wall, and the convex ring 212 can rotate relative to the circumferential wall.

[0079] The shell 1 comprises the sleeve part 11. The sleeve part 11 is provided with a belt outlet 112 at one axial end, and the belt outlet 22 extends from the belt outlet 112. The belt core 2 is provided with a limiting part 24 corresponding to the position of the belt outlet 112, the limiting part 24 is clamped along the circumferential direction of the belt outlet 112, and the axial movement of the belt core 2 is prevented.

[0080] The above embodiments and drawings are not limited to the product form and style of the present application, and any appropriate changes or modifications made by any ordinary skilled person in the art shall be considered as not departing from the patent scope of the present application.
