DETAILED DESCRIPTION
[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
[0023] Please refer to Figure 1 as well as Figure 2 A rotation limiting structure of a heat transfer machine is provided on an extension arm 17 of the heat transfer machine, and includes a limiting member 3 and a stop member 4. The extension arm 17 includes a first rotating shaft 1 and a second rotating shaft 2 that are rotatably connected. The limiting member 3 is provided on the first rotating shaft 1, and a movable groove 5 is provided on the second rotating shaft 2.

[0024] As can be seen from the above description, the beneficial effect of the present invention is that the rotation limit structure provided by the present invention can limit the rotation angle of the heating plate 15 of the thermal transfer machine, wherein the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other, driving the limit member 3 to rotate, and the limit member 3 can abut against the stop member 4 during the rotation stroke to drive the stop member 4 to move in the movable groove 5, until the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a preset angle, and the stop member 4 abuts against the groove wall of the movable groove 5, so that the stop member 4 acts as a stop for the limit member 3, and at this time the first rotating shaft 1 and the second rotating shaft 2 cannot continue to rotate. The rotation limit structure designed by the present invention realizes the rotation limit function through a mechanical structure, and its structure is simple, reliable and has a long service life.
[0025] Furthermore, a first sliding groove 7 is provided on the second rotating shaft 2 , and the limiting member 3 is movably disposed in the first sliding groove 7 .
[0026] As can be seen from the above description, the limiting member 3 slides along the extension direction of the first sliding groove 7, which can improve the smoothness of the rotation of the extension arm 17 of the rotation limiting structure and the controllability of the rotation limiting.
[0027] Furthermore, the second rotating shaft 2 is close to one end of the first rotating shaft 1 to form a receiving groove 8, and the end of the first rotating shaft 1 and the movable groove 5 are enclosed to form an receiving cavity, and the limiting member 3 and the stop member 4 are both arranged in the receiving cavity, and the movable groove 5 is provided in the receiving cavity.
[0028] From the above description, it can be seen that an accommodating cavity is formed between the first rotating shaft 1 and the second rotating shaft 2, so that the limiting member 3 and the stop member 4 are both arranged in a relatively sealed space, which can avoid adverse phenomena such as parts dislocation and foreign objects affecting the rotation of the extension arm 17 when the rotary limiting structure rotates. The rotary limiting structure has high reliability and long service life.
[0029] Furthermore, a second sliding groove 9 is provided on the first rotating shaft 1 , and the stopper 4 is provided in the second sliding groove 9 .
[0030] From the above description, it can be seen that the second sliding groove 9 can improve the smoothness of the relative rotation between the first rotating shaft 1 and the second rotating shaft 2, which can improve the smoothness of the rotation of the extension arm 17 using the rotation limiting structure and the controllability of the rotation limiting.
[0031] Furthermore, the second chute 9 is an arc-shaped strip groove, a gap is formed between the two ends of the second chute 9, and the limiting member 3 is arranged at a position corresponding to the gap.
[0032] It can be seen from the above description that the rotation limiting structure can achieve a 360-degree rotation limiting function.
[0033] Furthermore, the second rotating shaft 2 is provided with at least one limiting groove 6 that cooperates with the limiting member 3 .
[0034] It can be seen from the above description that when the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a preset angle, the limiting member 3 enters the limiting groove 6 to perform a positioning function.
[0035] Furthermore, the limiting member 3 includes a connecting portion 10 and a telescopic portion 11, one end of the connecting portion 10 is connected to the first rotating shaft 1, and the telescopic portion 11 is telescopically arranged at the other end of the first rotating shaft 1, and the outer contour of the telescopic portion 11 matches the inner contour of the limiting groove 6.
[0036] From the above description, it can be seen that when the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a preset angle, the telescopic part 11 can enter the limiting groove 6. The operator can apply a little force to make the telescopic part 11 disengage from the limiting groove 6, and then control the first rotating shaft 1 and the second rotating shaft 2 to continue rotating in the same direction until the limiting member 3 is stopped and cannot continue to rotate under the action of the stop member 4 and the movable groove 5.
[0037] Furthermore, the stop member 4 is a rolling ball, and the movable groove 5 includes a first stop groove 12, a connecting groove 13 and a second stop groove 14 which are connected in sequence. The lengths of the first stop groove 12 and the second stop groove 14 are both equal to the diameter of the rolling ball, and the connecting groove 13 is arranged at the midpoint of the length direction of the movable groove 5.
[0038] It can be seen from the above description that the rotation limiter 3 can limit the extension arm 17 in a 360° clockwise direction and a 360° counterclockwise direction.
[0039] Furthermore, a limiting groove 6 is provided on the second rotating shaft 2 , and the limiting groove 6 is arranged at a position corresponding to the movable groove 5 .
[0040] From the above description, it can be seen that when the first rotating shaft 1 and the second rotating shaft 2 complete a relative rotation of 360°, the limit groove 6 can play a positioning role on the limit member 3, so that the positions of the first rotating shaft 1 and the second rotating shaft 2 can be relatively fixed, avoiding rotation between the first rotating shaft 1 and the second rotating shaft 2.
[0041] Furthermore, the first limiting groove 6 is communicated with the connecting groove 13 .
[0042] Example 1
[0043] Please refer to Figures 1 to 5 The first embodiment of the present invention is to provide a rotation limiting structure of a heat transfer machine, wherein the rotation limiting structure is arranged on the extension arm 17 of the heat transfer machine, as shown in FIG. Figure 1 and Figure 5 As shown, the heat transfer machine described in this embodiment includes a base, an extension arm 17 and a heating plate 15. Two carrier plates 16 are provided on the base. The extension arm 17 can be rotatably installed on the base. The extension arm 17 is connected to the heating plate 15. The heating plate 15 is moved above the two carrier plates 16 through the rotatable extension arm 17. When the transfer of the product on one of the carrier plates 16 is completed, the heating plate 15 can be moved to the other carrier plate 16 to transfer the product while the operator is loading and unloading and laminating the product, which greatly reduces the idle time of the heating plate 15 and improves printing efficiency.
[0044] The extension arm 17 can be used to arrange a wiring harness. To protect the wiring harness, this embodiment provides a rotational limit structure to limit the rotation of the extension arm 17 of the thermal transfer machine. Specifically, the rotational limit structure includes a limit member 3 and a stop member 4. The extension arm 17 includes a first rotating shaft 1 and a second rotating shaft 2 that are rotatably connected. The limit member 3 is disposed on the first rotating shaft 1. The second rotating shaft 2 is provided with a movable groove 5. The stop member 4 is movably disposed in the movable groove 5. When the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other, the limit member 3 and the stop member 4 contact each other, driving the stop member 4 to move along the movable groove 5.
[0045] Reference Figure 2 、 Figure 3 It is easy to see that when the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other, the limit member 3 is driven to rotate. The limit member 3 can contact the stop member 4 during the rotation stroke to drive the stop member 4 to move in the movable groove 5 until the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a preset angle, and the stop member 4 contacts the groove wall of the movable groove 5 so that the stop member 4 acts as a stop for the limit member 3. At this time, the first rotating shaft 1 and the second rotating shaft 2 cannot continue to rotate.
[0046] according to Figure 1 It is easy to see that the second rotating shaft 2 is located near one end of the first rotating shaft 1, and the end of the first rotating shaft 1 and the movable groove 5 enclose an accommodating cavity. The limiter 3 and the stopper 4 are both located in the accommodating cavity, and the movable groove 5 is provided in the accommodating cavity. In this embodiment, the stopper 4 and the limiter 3 are both located in a sealed accommodating cavity, which can prevent the stopper 4 and the limiter 3 from dislocating during the rotation of the extension arm 17, thereby improving the reliability and service life of the extended rotation limit structure.
[0047] Please refer to further Figure 2 and Figure 3 In this embodiment, the second rotating shaft 2 is provided with a first sliding groove 7, in which the limiting member 3 is movably disposed. The first rotating shaft 1 is provided with a second sliding groove 9, in which the stopping member 4 is disposed. When the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other, the limiting member 3 slides along the first sliding groove 7 relative to the second rotating shaft 2, and the stopping member 4 slides along the second sliding groove 9 relative to the first rotating shaft 1, thereby improving the smoothness of the rotation of the extension arm 17.
[0048] Reference Figure 2 It can also be seen that in this embodiment, the second chute 9 is an arc-shaped strip groove, with a notch formed between the two ends of the second chute 9, and the limit member 3 is located corresponding to the notch. The stop member 4 is a rolling ball, and the movable groove 5 includes a first stop groove 12, a connecting groove 13, and a second stop groove 14, which are sequentially connected. The length of the first stop groove 12 and the second stop groove 14 are both equal to the diameter of the rolling ball. The connecting groove 13 is located at the midpoint of the length of the movable groove 5.
[0049] For easier understanding, please refer to Figure 4 As an example: in this embodiment, the position of the limit member 3 facing the connecting groove 13 is used as the starting point of the stroke, and the first rotating shaft 1 rotates clockwise relative to the second rotating shaft 2; when the limit member 3 is at the starting point of the stroke, the ball is located in the second stop groove 14, and in the process of the first rotating shaft 1 rotating 360 degrees counterclockwise relative to the second rotating shaft 2, when the limit member 3 moves to the position of the second stop groove 14, the limit member 3 conflicts with the stop member 4 to drive the stop member 4 to move from the second stop groove 14 to the first stop groove 12 until the stop member 4 conflicts with the groove wall of the first stop groove 12. At this time, the stop member 4 acts as a stop for the limit member 3 to prevent the first rotating shaft 1 from continuing to rotate clockwise relative to the second rotating shaft 2. At this time, the limit member 3 is just facing the position of the connecting groove 13, that is, at this time, the first rotating shaft 1 rotates 360 degrees clockwise relative to the second rotating shaft 2, and the first rotating shaft 1 can rotate counterclockwise relative to the second rotating shaft 2.
[0050] In this embodiment, in order to position the first rotating shaft 1 and the second rotating shaft 2 when the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other to a preset angle, at least one limiting groove 6 is provided in the first sliding groove 7 to cooperate with the limiting member 3. As a preferred embodiment, please refer to Figure 2 The limiting member 3 includes a connecting portion 10 and a telescopic portion 11. One end of the connecting portion 10 is connected to the first rotating shaft 1, and the telescopic portion 11 is telescopically arranged at the other end of the first rotating shaft 1. The outer contour of the telescopic portion 11 matches the inner contour of the limiting groove 6. When the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a predetermined angle, the telescopic portion 11 can enter the limiting groove 6. The operator can then control the first rotating shaft 1 and the second rotating shaft 2 to continue rotating in the same direction until the limiting member 3 is stopped by the stop member 4 and the movable groove 5 and cannot rotate further.
[0051] Please refer to Figure 4 It can be seen that the rotation limiting mechanism of this embodiment is provided with two limiting grooves 6, one of which is provided at the position corresponding to the movable groove 5, and the first limiting groove 6 is connected to the connecting groove 13. When the first rotating shaft 1 and the second rotating shaft 2 complete a relative rotation of 360°, the limiting groove 6 can play a positioning role for the limiting member 3, so that the positions of the first rotating shaft 1 and the second rotating shaft 2 can be relatively fixed, and the first rotating shaft 1 and the second rotating shaft 2 can be prevented from rotating back. The other limiting groove 6 is provided in the first sliding groove 7. When the first rotating shaft 1 and the second rotating shaft 2 complete a relative rotation of 180°, the other limiting groove 6 can play a positioning role for the limiting member 3.
[0052] In summary, the rotation limiting structure provided by the present invention can limit the rotation angle of the heating plate 15 of the thermal transfer machine, wherein the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other, driving the limiting member 3 to rotate. The limiting member 3 can abut against the stop member 4 during the rotation stroke to drive the stop member 4 to move in the movable groove 5 until the first rotating shaft 1 and the second rotating shaft 2 rotate relative to each other by a preset angle, and the stop member 4 abuts against the groove wall of the movable groove 5 so that the stop member 4 acts as a stop for the limiting member 3. At this time, the first rotating shaft 1 and the second rotating shaft 2 cannot continue to rotate. The rotation limiting structure designed by the present invention realizes the rotation limiting function through a mechanical structure, and its structure is simple, reliability is high, and service life is long.
