In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] like Figures 1 to 6 As shown, the label ribbon box of the utility model comprises: a box body 1 and a tape outlet wheel 2, on which a ribbon strip 3 is wound, the tape outlet wheel 2 is rotatably installed in the box body 1, and one end of the ribbon strip 3 extends out through a tape outlet provided in the box body 1; an elastic energy storage component 4 and a limiting mechanism 5, the limiting mechanism 5 having a fixed unit 51 and a synchronous rotation unit 52, the elastic energy storage component 4 being connected to the synchronous rotation unit 52 and the tape outlet wheel 2 respectively, so that: when the tape outlet wheel 2 rotates, the elastic energy storage component 4 stores energy and after reaching a certain threshold, the tape outlet wheel 2 drives the synchronous rotation unit 52 to rotate relative to the fixed unit 51 through the elastic energy storage component 4; when the tape outlet wheel 2 does not rotate, the fixed unit 51 limits and fixes the synchronous rotation unit 52, so that the elastic energy storage component 4 releases the stored elastic potential energy, and the tape outlet wheel 2 is reversed to tighten the ribbon strip 3.
[0032] See also Figure 1 , box body 1, Figure 2 The box body 1 has an upper shell and a lower shell which are connected to each other. A containing space for a belt outlet wheel 2 to rotate is formed in the box body 1. The ribbon strip 3 wound on the belt outlet wheel 2 can extend out through a belt outlet of the box body 1.
[0033] See also Figure 1 , Figure 2 It should be noted that when the tape outlet wheel 2 changes from a rotating state to a non-rotating state, the ribbon strip 3 on the tape outlet wheel 2 will be loose to a certain extent in the box body 1. If the ribbon strip 3 cannot be tightened in time, it will affect the use of the ribbon box.
[0034] When the tape delivery wheel 2 in the ribbon cassette of the present application rotates counterclockwise to deliver the ribbon strip 3 out of the cassette body 1, the rotation of the tape delivery wheel 2 will drive the elastic energy storage member 4 to store elastic potential energy. When the elastic potential energy of the elastic energy storage member 4 is stored to a threshold value, the elastic energy storage member 4 and the synchronously rotating unit 52 will rotate synchronously with the tape delivery wheel 2 relative to the fixed unit 51, thereby realizing the storage of the elastic potential energy of the elastic energy storage member 4. When the tape delivery wheel 2 stops rotating, the fixed unit 51 of the limiting mechanism 5 can rotate the synchronously rotating unit 52. The position is limited to prevent the elastic potential energy released by the elastic energy storage component 4 from acting too much on the synchronous rotation unit 52. When the elastic potential energy is released by the elastic energy storage component 4, the elastic energy storage component 4 can drive the output wheel 2 to rotate clockwise, thereby tightening the ribbon strip 3 wound on the output wheel 2, and improving the use effect of the ribbon box. The present application can achieve the reversal of the output wheel 2 through the release of the elastic potential energy stored in the elastic energy storage component 4, and then automatically apply a certain tensioning force to the ribbon strip 3. It has the characteristics of simple structure and convenient operation, and is practical.
[0035] In one or more embodiments, the fixed unit 51 includes a first circular ring 511 fixedly installed in the box body 1 and a first baffle 512 inclined downwardly arranged on the inner side of the first circular ring 511; the synchronous rotation unit 52 includes a second circular ring 521 rotatably installed in the box body 1 and a second baffle 522 inclined upwardly arranged on the outer side of the second circular ring 521; wherein the first circular ring 511 is coaxial with the second circular ring 521, and the first circular ring 511 is located on the outer side of the second circular ring 521; the belt output wheel 2 has a first baffle 21 and a second baffle 22 relative to each other, and a boss 211 smaller than the outer diameter of the first baffle 21 is formed at the bottom end of the first baffle 21, one end of the elastic energy storage component 4 is connected to the boss 211, and the other end of the elastic energy storage component 4 is connected to the inner surface of the second circular ring 521; the elastic energy storage component 4 is a coil spring; the first baffle 512 and the second baffle 522 are springs.
[0036] See also Figure 5 , Figure 6The elastic energy storage member 4 is a coil spring having an inner end and an outer end; the inner end of the coil spring is mounted on the outer surface of the boss 211 , and the outer end of the coil spring is mounted on the inner surface of the second ring 521 .
[0037] See also Figures 2 to 6 When the output wheel 2 rotates counterclockwise to deliver the color ribbon 3, the output wheel 2 drives the inner end of the coil spring to rotate. When the elastic potential energy of the coil spring is stored to a threshold value, the output wheel 2 drives the second ring 521 to rotate counterclockwise through the coil spring. At this time, the second baffle 522 that can produce elastic deformation and is inclined upward on the outer peripheral side of the second ring 521 contacts and passes over the first baffle 512. The first baffle 512 will not block the second baffle 522, that is, the second ring 521 can rotate relative to the first ring 511.
[0038] See also Figures 2 to 6 After the outlet wheel 2 stops rotating, the elastic potential energy stored in the coil spring is released. At this time, the outer end of the coil spring will drive the second ring 521 to rotate clockwise, so that the second baffle 522 on the second ring 521 contacts the first baffle 512 on the first ring 511, and the first baffle 512 forms a limit for the clockwise rotation of the second ring 521. At this time, the elastic potential energy of the coil spring can only be released toward the outlet wheel 2, and the inner end of the coil spring drives the outlet wheel 2 to rotate clockwise to tighten the ribbon strip 3.
[0039] In this way, the ribbon strip 3 can be automatically tightened, the possibility of malfunction of the ribbon cassette can be reduced, and the use effect of the ribbon cassette of the present application can be improved.
[0040] In one or more embodiments, a limiting groove 6 is formed on the outer peripheral side of the boss 211 , and a limiting protrusion 7 extending into the limiting groove 6 is formed on one end of the elastic energy storage member 4 connected to the boss 211 .
[0041] See also Figures 4 to 6 The inner end of the elastic energy storage member 4 is separable from the boss 211 of the tape outlet wheel 2, so that the tape outlet wheel 2 can be taken out of the box body 1, which is convenient for replacing the tape outlet wheel 2 or the ribbon strip 3, reduces the waste of the ribbon box, and is practical.
[0042] In one or more embodiments, the first ring 511 and the second ring 521 are made of hard plastic. In this way, the overall weight of the ribbon cassette can be reduced, and the production cost can be reduced.
[0043] In one or more embodiments, the outer diameter of the first rib 21 is greater than the outer diameter of the second rib 22 .
[0044] See also Figure 3 , Figure 4The first circular ring 511 is located in the space limited by the first rib 21, that is, the first circular ring 511, the second circular ring 521 and the elastic energy storage component 4 are all located in the space limited by the first rib 21 of the tape outlet wheel 2; in this way, the first circular ring 511 or the second circular ring 521 can be prevented from contacting the ribbon strip 3, thereby improving the use effect of the present application and reducing the space occupancy rate of the ribbon box, thereby being practical.
[0045] In one or more embodiments, the first rib 21 and the second rib 22 are connected to the box body 1 through a ball bearing. In this way, the abnormal sound emitted when the output wheel 2 rotates can be reduced, and the wear of the output wheel 2 or the box body 1 can be reduced, thereby extending the service life of the ribbon box.
[0046] In one or more embodiments, a polytetrafluoroethylene coating is sprayed on the surface of the first rib 21 and the second rib 22. It should be noted that polytetrafluoroethylene has a certain self-lubricating and anti-corrosion effect. Through this arrangement, the smoothness of the rotation of the output wheel 2 can be improved while reducing the pollution of the color strip 3 on the output wheel 2.
[0047] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
