Description

Technical Field

[0001] This utility model mainly relates to the field of thermal transfer printer technology, specifically to a thermal transfer printer ribbon mounting structure. Background Technology

[0002] Thermal transfer printers transfer the toner coating on a ribbon to paper or other materials by heating it. Because the coating material on the ribbon can be selected as needed, it produces strong adhesion. In addition, the choice of printing media further ensures that the printed text is not affected by external factors. Text printed by thermal transfer can be preserved for a long time, will not fade, will not be worn by contact with solvents, and will not be deformed or discolored by high temperatures.

[0003] When installing the ribbon in a thermal transfer printer, it is necessary to install a winding spool with the ribbon wound on it and a rewind spool for rewinding the used ribbon. However, the specifications of the winding spool and the rewind spool are very diverse, and the existing ribbon installation structure can only install winding spools and rewind spools of fixed specifications, which limits the range of choices. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a ribbon mounting structure for a thermal transfer printer to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a ribbon mounting structure for a thermal transfer printer, including a mounting bracket, wherein a first mounting mechanism and a second mounting mechanism distributed in a horizontal direction are provided on the top of the mounting bracket;

[0008] Both the first and second installation mechanisms include a set of movable plates. The two movable plates are driven to move relative to each other and are rotatably mounted with rotating rods. Limiting rods are fixedly mounted at the opposite ends of the two rotating rods, and the radius of the limiting rods gradually decreases towards the inner side of the two movable plates.

[0009] A motor is mounted on the end of one of the rotating rods in the second mounting mechanism away from the limit rod.

[0010] Furthermore, both the first and second mounting mechanisms include a slide rail, which is fixedly mounted on the top of the mounting bracket and has a first slider and a second slider slidably mounted inside it. The first slider and the second slider are respectively fixedly mounted on the bottom of two movable plates in the same group and are threadedly connected to a lead screw rotatably mounted inside the slide rail in opposite directions. A handle is fixedly mounted on one end of the lead screw.

[0011] Furthermore, the mounting bracket has two through slots, which are located on both sides of the first mounting mechanism and the second mounting mechanism, respectively. The bottom of the mounting bracket is equipped with a telescopic cylinder, the telescopic end of which is vertically downward and fixedly mounted with a tape laying plate, which is located between the two through slots.

[0012] Furthermore, the tape laying plate has rounded chamfers on both sides near the two through slots.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages: after the two movable plates are driven to approach each other, the two limiting rods approach each other synchronously, and the radius of the limiting rods gradually decreases towards the inner side of the two movable plates. Therefore, after the two limiting rods approach each other at different distances, their outer sides can abut against the inner wall of the winding drum or winding drum of different specifications, so that winding drums or winding drums of different specifications can be installed.

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "page", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0023] See attached document Figure 1-2 A thermal transfer printer ribbon mounting structure includes a mounting bracket 1, wherein a first mounting mechanism 2 and a second mounting mechanism 3 distributed horizontally are provided on the top of the mounting bracket 1.

[0024] The first installation mechanism 2 and the second installation mechanism 3 both include a set of movable plates 231. The two movable plates 231 are driven to move relative to each other, and each is rotatably mounted with a rotating rod 232. The opposite ends of the two rotating rods 232 are fixedly mounted with a limiting rod 233. The radius of the limiting rod 233 gradually decreases towards the inner side of the two movable plates 231.

[0025] A motor 4 is mounted on the end of one of the rotating rods 232 in the second mounting mechanism 3 away from the limit rod 233.

[0026] In this embodiment, after the winding drum is placed between the two limiting rods 233, the two movable plates 231 are driven to move closer to each other, and the two limiting rods 233 move closer to each other synchronously until their outer sides abut against the inner wall of the winding drum. This limits the winding drum between the two limiting rods 233, and it can rotate with the rotating rod 232, thereby releasing the carbon tape on the winding drum for use, thus completing the installation of the winding drum. Similarly, the installation of the winding drum can be completed through the second installation mechanism 3. After the carbon tape led out from the winding drum is adhered to the winding drum, the motor 4 is started, which drives the winding drum to rotate and wind up the carbon tape used on the winding drum.

[0027] The first mounting mechanism 2 and the second mounting mechanism 3 both include a slide rail 234. The slide rail 234 is fixedly mounted on the top of the mounting bracket 1, and a first slider 235 and a second slider 236 are slidably mounted inside it. The first slider 235 and the second slider 236 are respectively fixedly mounted on the bottom of two movable plates 231 in the same group, and are threadedly connected to a lead screw 237 rotatably mounted inside the slide rail 234 in opposite directions. A handle 238 is fixedly mounted on one end of the lead screw 237.

[0028] In this embodiment, after the grip 238 drives the lead screw 237 to rotate, the first slider 235 and the second slider 236 can slide relative to each other in the slide rail 234, and the two movable plates 231 fixedly connected to the first slider 235 and the second slider 236 maintain synchronous relative movement.

[0029] The mounting bracket 1 has two through slots 101, which are located on the sides of the first mounting mechanism 2 and the second mounting mechanism 3, respectively. The bottom of the mounting bracket 1 is equipped with a telescopic cylinder 5. The telescopic end of the telescopic cylinder 5 is vertically downward and is fixedly installed with a tape laying plate 6. The tape laying plate 6 is located between the two through slots 101.

[0030] In this embodiment, after the carbon ribbon on the winding drum is drawn out, it passes through the through slot 101 close to the first mounting mechanism 2, and then the carbon ribbon is pressed against the tape laying plate 6. Then the carbon ribbon is passed through the through slot 101 close to the second mounting mechanism 3. Finally, the end of the carbon ribbon is glued to the take-up drum with adhesive. At this time, the telescopic cylinder 5 is activated to drive the tape laying plate 6 to descend until the carbon ribbon on the tape laying plate 6 is pressed against the printing paper and can then be used.

[0031] It should be noted that the ribbon laying plate 6 has rounded chamfers on both sides near the two through slots 101 to reduce damage to the carbon ribbon.

[0032] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0033] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
