For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] like Figures 1 to 4 As shown, the ribbon cassette of the utility model comprises: a cassette body 1, a tape-out wheel 2 and a tape-receiving wheel 3, wherein the tape-out wheel 2 and the tape-receiving wheel 3 are rotatably mounted in the cassette body 1; a ribbon strip 4, wherein one end of the ribbon strip 4 is mounted on the tape-out wheel 2, and the other end extends out of the cassette body 1 through the tape-out port of the cassette body 1, and enters the cassette body 1 through the tape-in port of the cassette body 1 and is connected to the tape-receiving wheel 3; a first gear 5 and a second gear 6, wherein the first gear 5 is arranged on the tape-out wheel 2 or the tape-receiving wheel 3, and the second gear 6 is rotatably mounted in the cassette body 1 and meshes with the first gear 5; an elastic energy storage component 7 and a magnetic attraction component, wherein the magnetic attraction component is mounted in the cassette body 1, and the elastic energy storage component 7 has an inner end and an outer end, wherein the inner end is connected to the second gear 6, and the outer end is magnetically attracted by the magnetic attraction component.
[0028] See also Figure 1 , Figure 2 The first gear 5 is meshed and connected with the second gear 6, and the first gear 5 can be installed on the tape-out wheel 2 or the tape-receiving wheel 3; the magnetic attraction component is installed on the box body 1, and the magnetic attraction component corresponds to the second gear 6. The elastic energy storage component 7 is a coil spring, and the elastic energy storage component 7 has an inner end and an outer end. The inner end of the elastic energy storage component 7 is fixedly connected to the second gear 6, and the outer end of the elastic energy storage component 7 is attracted by the magnetic attraction component.
[0029] When the first gear 5 is installed on the output wheel 2: when the output wheel 2 delivers the tape and the take-up wheel 3 takes up the tape, the output wheel 2 rotates counterclockwise and the take-up wheel 3 rotates clockwise, and the ribbon strip 4 on the output wheel 2 can be wound onto the take-up wheel 3; the output wheel 2 rotates counterclockwise while driving the first gear 5 to rotate counterclockwise, and then the second gear 6 meshing with the first gear 5 rotates clockwise. At this time, since the outer end of the elastic energy storage component 7 is attracted by the magnetic attraction component and the inner end is fixedly connected to the bottom of the second gear 6, the elastic potential energy of the elastic energy storage component 7 can be stored. When the elastic potential energy of the elastic energy storage component 7 is stored to a threshold value, the outer end of the elastic energy storage component 7 overcomes the attraction of the magnetic attraction component and rotates synchronously with the second gear 6, and the elastic potential energy is always stored.
[0030] When the tape delivery wheel 2 and the tape take-up wheel 3 stop rotating, since the outer end of the elastic energy storage member 7 is attracted and fixed by the magnetic attraction component, the elastic potential energy stored in the elastic energy storage member 7 will be released through the inner end, and then the second gear 6 will be controlled to reverse, so that the first gear 5 meshing with the second gear 6 and fixedly connected to the tape delivery wheel 2 will rotate, so that the tape delivery wheel 2 can tighten the wound ribbon strip 4 between it and the tape take-up wheel 3, and avoid the ribbon strip 4 from getting stuck on the ribbon box; the present application releases the stored elastic potential energy through the elastic energy storage member 7, so that the second gear 6 drives the first gear 5 and the tape delivery wheel 2 to reverse, and then applies a certain pre-tightening force to the ribbon strip 4 in a relaxed state, so as to avoid the ribbon strip 4 from getting stuck, thereby improving the use effect of the present application, having the characteristics of simple structure and practicality.
[0031] In one or more embodiments, the magnetic attraction assembly includes a first magnet 81 and a second magnet 82 that attract each other, the first magnet 81 is installed at the outer end of the elastic energy storage component 7, and the second magnet 82 is installed in the box body 1; the first magnet 81 and the second magnet 82 are circular ring structures.
[0032] See also Figure 2 , Figure 4 The second magnet 82 is fixed in the box body 1, and the first magnet 81 is fixed to the outer end of the elastic energy storage component 7; through this configuration, the second magnet 82 can attract the first magnet 81, and by reasonably selecting the types of the first magnet 81 and the second magnet 82, the attraction between the first magnet 81 and the second magnet 82 can be greater than the elastic potential energy released by the elastic energy storage component 7; at the same time, by configuring the first magnet 81 and the second magnet 82 as a circular ring structure, the stability of the magnetic attraction between the first magnet 81 and the second magnet 82 can be guaranteed, thereby improving the use effect of the present application.
[0033] In one or more embodiments, an electromagnetic shielding cloth is installed on one side of the second magnet 82 in the box body 1. The electromagnetic shielding cloth is not shown in the drawings; through this configuration, the magnetic force of the second magnet 82 can be partially shielded to prevent the second magnet 82 from attracting metal that can be magnetically attracted to the ribbon box, thereby ensuring the stability of the ribbon box.
[0034] In one or more embodiments, the pitch circle radius of the first gear 5 is smaller than the pitch circle radius of the second gear 6. With this configuration, the number of revolutions of the second gear 6 relative to the first gear 5 can be reduced, thereby reducing the generation of abnormal noise inside the ribbon cassette.
[0035] In one or more embodiments, the first gear 5 and the second gear 6 are made of hard plastic. This configuration can reduce the overall weight of the ribbon cassette, reduce the production cost of the ribbon cassette, and is practical.
[0036] In one or more embodiments, a groove 61 is formed on a surface of the second gear 6 close to the box body 1 , and the elastic energy storage member 7 is located in the groove 61 .
[0037] See also Figure 2 , Figure 4 The elastic energy storage component 7 and the first magnet 81 are both located in the groove 61. Through this arrangement, the space occupied by the magnetic attraction component and the elastic energy storage component 7 can be reduced, the internal space of the ribbon box can be further optimized, and the overall volume of the ribbon box can be reduced.
[0038] In one or more embodiments, the first gear 5 and the second gear 6 are rotatably connected to the inner surface of the box body 1 through a plane bearing. The plane bearing is not shown in the drawings; by using a miniature plane bearing to support the first gear 5 and the second gear 6, the abnormal noise generated when the first gear 5 and the second gear 6 rotate can be reduced, and the smoothness of the rotation of the first gear 5 and the second gear 6 can be improved, thereby improving the use effect of the ribbon box.
