The release gear and the recovery gear of the present application are driven by belts, and the belt drive can reduce the pressure on the paper tape, thereby reducing the risk of paper tape breakage; and the first winding part is closer to the extension part than the second winding part, so the travel of the paper tape from the first winding part to the extension part is relatively short. Therefore, the paper tape transmission structure of the present application can reduce the pressure on the paper tape through belt drive, thereby reducing the risk of paper tape breakage, and the paper tape travel is relatively short when releasing the paper tape.

Description

Technical Field

[0001] The present application relates to the technical field of paper tape transmission, and in particular to a paper tape transmission structure and a correction device. Background Art

[0002] Correction tape is a stationery item with a correction function. It is usually made of a layer of chemically synthesized pigment adhered to a paper tape. When in use, the layer of chemically synthesized pigment separates from the paper tape and covers the typos on the paper to achieve the correction effect.

[0003] In the related art, the correction tape utilizes a paper tape transmission structure to drive the release of the paper tape. Usually, the paper tape transmission structure includes a release gear and a recovery gear. The release gear is directly meshed with the recovery gear. The release gear is located on the side away from the paper tape outlet, and the recovery gear is located between the paper tape outlet and the release gear. When in use, a new paper tape is released by the release gear, and the used paper tape is recovered by the recovery gear. When this structure drives the paper tape, the pressure on the paper tape is greater, and the risk of the paper tape breaking is greater. In addition, since the release gear is located on the side away from the paper tape outlet, the paper tape has a larger travel when released and has a lower strength. Utility Model Content

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] Reference Figures 1 to 5 The first embodiment of the present application provides a paper tape transmission structure, including:

[0038] A bracket 210, wherein the bracket 210 is provided with an extension portion 211;

[0039] Release gear 220;

[0040] Recycling gear 230;

[0041] a first winding portion;

[0042] The second winding portion, the first winding portion and the second winding portion are all installed on the bracket 210, and the first winding portion is located between the second winding portion and the extension portion 211. The first winding portion is wound with a paper tape 300, and the paper tape 300 is rolled up on the second winding portion after passing through the extension portion 211. The release gear 220 is connected to the first winding portion, and the recovery gear 230 is connected to the second winding portion; the recovery gear 230 is connected to the release gear 220 through a belt 240; the release gear 220 is used to drive the first winding portion, the recovery gear 230, and the second winding portion to rotate when rotating.

[0043] According to the paper tape transmission structure of the embodiment of the present application, at least the following beneficial effects are achieved: in the paper tape transmission structure of the present application, the paper tape 300 is released from the first winding part, and then passes through the extension part 211. The paper tape 300 located in the extension part 211 is used, and the release paper after use is rolled up in the second winding part. By rotating the release gear 220, the first winding part, the recovery gear 230, and the second winding part are driven to rotate, so that the first winding part releases the paper tape 300, the paper tape 300 passes through the extension part 211, and then the paper tape 300 is recovered by the second winding part. The release gear 220 and the recovery gear 230 of the present application are driven by the belt 240, and the belt 240 transmission can reduce the pressure on the paper tape 300, thereby reducing the risk of the paper tape 300 breaking; and the first winding part is closer to the extension part 211 than the second winding part, so the travel of the paper tape 300 from the first winding part to the extension part 211 is relatively short. Therefore, the paper tape transmission structure of the present application can reduce the pressure on the paper tape 300 by transmitting through the belt 240, thereby reducing the risk of the paper tape 300 breaking, and the travel of the paper tape 300 is shorter when the paper tape 300 is released.

[0044] It should be noted that since the hub of the release gear 220 is fixedly connected to the first winding part, the release gear 220 can drive the first winding part to rotate when it rotates; the hub of the recovery gear 230 is fixedly connected to the second winding part, so the recovery gear 230 can drive the second winding part to rotate when it rotates.

[0045] It is understandable that, referring to Figure 3 The release gear 220 is provided with a first convex portion on the side opposite to the first winding portion, and the first convex portion is provided with a first annular groove 221. The recovery gear 230 is provided with a second convex portion on the side opposite to the second winding portion, and the second convex portion is provided with a second annular groove 231. One end of the belt 240 is sleeved in the first annular groove 221, and the other end is sleeved in the second annular groove 231. The first annular groove 221 and the second annular groove 231 can limit the belt 240, preventing the belt 240 from detaching from the first convex portion or the second convex portion during movement.

[0046] It is understandable that the first winding portion is provided with a first rotating shaft 250, the hub of the release gear 220 is passed through the first rotating shaft 250, the bracket 210 is provided with a first through hole 212, and the first rotating shaft 250 is movably passed through the first through hole 212. When the release gear 220 rotates, it drives the first rotating shaft 250 to rotate.

[0047] It is understandable that the second winding portion is provided with a second rotating shaft 260, the hub of the recovery gear 230 is passed through the second rotating shaft 260, the bracket 210 is provided with a second through hole 213, and the second rotating shaft 260 is movably passed through the second through hole 213. When the recovery gear 230 rotates, it drives the second rotating shaft 260 to rotate.

[0048] It can be understood that it also includes a shell 100, a cavity is formed in the shell 100, the bracket 210, the release gear 220, the recovery gear 230, the first winding part, and the second winding part are all arranged in the cavity, and a first opening 110 connected to the cavity is provided on one side of the shell 100, and the extension part 211 is passed through the first opening 110, and the extension part 211 is located outside the shell 100.

[0049] It is understandable that, referring to Figure 3 and Figure 4 An inner ratchet 222 is provided on one side of the first convex portion, and the housing 100 is provided with a first support column 141, which is penetrated by the inner ratchet 222, and a plurality of inner teeth are provided on the inner circumference of the inner ratchet 222; the paper tape transmission structure also includes an outer ratchet 223, and a plurality of ratchet pawls are provided on the outer circumference of the outer ratchet 223, the ratchet is sleeved on the first support column 141, and the outer ratchet 223 is located inside the inner ratchet 222, and the ratchet pawls of the outer ratchet 223 are in contact with the inner teeth.

[0050] An internal meshing ratchet structure is formed between the inner ratchet 222 and the outer ratchet 223. The internal meshing ratchet structure has the advantages of small size, compact structure, and high transmission efficiency. The internal meshing ratchet structure can enable the release gear 220 to rotate continuously in the first direction, and can also enable the release gear 220 to rotate slightly in the second direction. The first direction is opposite to the second direction, thereby realizing the release and limited range rotation of the paper tape, so as to facilitate the adjustment of the position of the paper tape 300.

[0051] It should be noted that the housing 100 is further provided with a second support column 142 , and the second support column 142 is penetrated through the second protrusion of the recovery gear 230 .

[0052] It can be understood that a second opening 120 communicating with the cavity is provided on the other side of the housing 100 ; part of the gear teeth of the release gear 220 are passed through the second opening 120 and are located outside the housing 100 .

[0053] It should be noted that some of the teeth of the release gear 220 are passed through the second opening 120 and are located outside the shell 100. Therefore, the user can drive the release gear 220 to rotate by turning the teeth located outside the shell 100, thereby driving the first winding part, the recovery gear 230, and the second winding part to rotate.

[0054] It can be understood that the first winding portion is further provided with two first annular baffles 251, which are spaced apart on the first rotating shaft 250, and the paper tape 300 is wound around the first rotating shaft 250, and the paper tape 300 is located between the two first annular baffles 251. The paper tape 300 is limited by the two first annular baffles 251 to prevent the paper tape 300 from being offset when the paper tape 300 is released.

[0055] It is understandable that the second winding portion is further provided with two second annular baffles 261, which are spaced apart on the second rotating shaft 260, and the used paper tape 300 is wound on the second rotating shaft 260, and the paper tape 300 is located between the two second annular baffles 261. The paper tape 300 is limited by the two second annular baffles 261 to prevent the paper tape 300 from being offset when the paper tape 300 is recycled.

[0056] It is understandable that, referring to Figure 5 A bending surface is provided on a side of the extension portion 211 opposite to the first opening 110 , and a first limiting groove 2111 is provided on the bending surface. The paper tape 300 is laid in the first limiting groove 2111 .

[0057] It can be understood that the bracket 210 is provided with an annular plate 214, which is arranged on one side of the first winding part, and a second limiting groove 2141 is provided on the side of the annular plate 214 opposite to the first winding part. The paper tape 300 passing through the first limiting groove 2111 is wound up in the second winding part after passing through the second limiting groove 2141.

[0058] After coming out of the first rotating shaft 250, the paper tape 300 is wound along one side of the curved surface to the other side of the curved surface, and then wound along the second limiting groove 2141 to the second rotating shaft 260. The first limiting groove 2111 and the second limiting groove 2141 are used to prevent the paper tape 300 from deflecting during movement.

[0059] It is understandable that the housing 100 includes an upper cover 130 and a lower cover 140, the upper cover 130 covers the lower cover 140, and a cavity is formed between the upper cover 130 and the lower cover 140. The upper cover 130 and the lower cover 140 can be locked by nuts and screws.
