[0002] In a cup hot press, a tightening structure is a device for wrapping a cylindrical article in a thermal printing sticker. In the related art, the tightening structure mainly tightens or opens the wrapping angle of a flexible heating plate by manually pushing or pulling a connecting rod or an electric push rod to push or pull the connecting rod, so as to adjust the tightness of the cup wrapped in the flexible heating plate.

[0037] It can be understood that in other embodiments, the processing of the workpiece to be processed by the hot pressing system 1000 and the hot pressing device 100 can be only the processing of the workpiece to be processed by the pressure generated by the hot pressing device 100, and the present application does not limit this.

[0038] Please refer to Figures 2 to 4 , Figure 2 which is a schematic structural diagram of a hot pressing device provided by an embodiment of the present application, Figure 3 which is a cross-sectional view of a hot pressing device provided by an embodiment of the present application in an expanded state, Figure 4 which is a cross-sectional view of a hot pressing device provided by an embodiment of the present application in a tightened state.

[0039] An embodiment of the present application provides a hot pressing device 100, which includes a housing 10, a flexible heating component 20, an adjusting component 30, and a driving component 40. The housing 10 has a receiving cavity 11. The heating component 20 is received in the receiving cavity 11 and encloses a receiving space 20c, and the receiving space 20c extends along the axial direction of the central axis Z. The heating component 20 includes a first end 20a and a second end 20b that are oppositely arranged in the circumferential direction of the central axis Z. The first end 20a is fixedly connected to the housing 10, and the second end 20b is movably arranged on the housing 10 so that the radial dimension of the receiving space 20c formed by enclosing the heating component 20 can change, that is, the receiving space 20c formed by enclosing the heating component 20 can be tightened or expanded in the radial direction. The adjusting component 30 surrounds at least part of the heating component 20 along the circumferential direction of the central axis Z. The adjusting component 30 is movably installed in the housing 10 along the circumferential direction of the central axis Z, and the adjusting component 30 is connected to the second end 20b of the heating component 20. The driving component 40 is at least partially received in the receiving cavity 11. The driving component 40 is connected to the adjusting component 30, and the driving component 40 is used to drive the adjusting component 30 to move along the circumferential direction of the central axis Z so that the adjusting component 30 drives the heating component 20 to be tightened or expanded in the radial direction of the central axis Z, thereby adjusting the radial dimension of the receiving space 20c formed by enclosing the heating component 20. When the second end 20b moves towards the direction close to the first end 20a, the heating component 20 can be tightened radially. When the second end 20b moves towards the direction away from the first end 20a, the heating component 20 can be expanded radially. It should be understood that the above central axis Z is the central axis of the movement trajectory of the adjusting component 30.

[0040] In the hot pressing device 100 provided by the present application, the first end 20a of the heating component 20 is fixedly connected to the housing 10, the second end 20b is movably arranged in the receiving cavity 11, and the driving component 40 drives the adjusting component 30 to drive the second end 20b of the heating component 20 to move along the circumferential direction of the central axis Z. When the second end 20b moves circumferentially along the central axis Z relative to the first end 20a under the action of the driving component 40 and the adjusting component 30, the receiving space 20c formed by enclosing the heating component 20 can be tightened or expanded radially, so that the heating component 20 can tightly wrap the workpieces to be processed with different shapes and sizes and perform hot pressing and transfer printing on the workpieces to be processed. Through the above design, the driving component 40 drives the adjusting component 30 to move circumferentially around the central axis Z, so that the heating component 20 is tightened or expanded, which is beneficial to reducing the space occupied by the driving component 40 and the adjusting component 30 in the receiving cavity 11 of the housing 10, making the layout of the hot pressing device 100 more compact, facilitating the development of the hot pressing device 100 towards the trend of miniaturization, and further improving the application range of the hot pressing device 100.

[0041] Please refer to Figures 2 to 4, in one embodiment, the housing 10 includes a first side plate 12, a second side plate 13, a third side plate 14, and a bottom plate 15 that are sequentially connected. The first side plate 12, the bottom plate 15, and the second side plate 13 are sequentially connected. The first side plate 12 and the second side plate 13 are oppositely arranged along the axial direction of the central axis Z. The third side plate 14 is connected between the first side plate 12 and the second side plate 13, and the third side plate 14 is also connected to the bottom plate 15. The first side plate 12, the second side plate 13, the third side plate 14, and the bottom plate 15 enclose a receiving cavity 11. The first side plate 12 has a first opening 121 that extends to the edge of the first side plate 12 facing the third side plate 14 and the edge of the first side plate 12 facing away from the bottom plate 15. The second side plate 13 has a second opening 131 that extends to the edge of the second side plate 13 facing the third side plate 14 and the edge of the second side plate 13 facing away from the bottom plate 15. The first opening 121 and the second opening 131 are oppositely arranged along the central axis Z, and the first opening 121 and the second opening 131 are used for placing or removing the workpiece to be processed.

[0042] Please refer to Figures 2 to 5 , Figure 5 is an assembly drawing of a driving component, an adjusting component, and a guiding component provided by an embodiment of the present application.

[0043] In one implementation, the adjusting component 30 includes a first adjusting member 31 and a second adjusting member 32 that are axially spaced apart along the central axis Z. The first adjusting member 31 is disposed on one side of the first side plate 12 facing the second side plate 13, and the second adjusting member 32 is disposed on one side of the second side plate 13 facing the first side plate 12. Both the first adjusting member 31 and the second adjusting member 32 circumferentially surround at least a part of the heating component 20 along the central axis Z, and the same ends of the first adjusting member 31 and the second adjusting member 32 are connected to the second end 20b of the heating component 20. The driving component 40 connects the first adjusting member 31 and the second adjusting member 32, and the driving component 40 is used to drive the first adjusting member 31 and the second adjusting member 32 to move synchronously in the circumferential direction around the central axis Z.

[0044] Specifically, both the first adjusting member 31 and the second adjusting member 32 can be open-loop gear rings, and the teeth of the first adjusting member 31 are disposed on the side of the first adjusting member 31 facing away from the heating component 20, and the teeth of the second adjusting member 32 are disposed on the side of the second adjusting member 32 facing away from the heating component 20. The driving component 40 drives the first adjusting member 31 and the second adjusting member 32 by connecting their gears, so that the first adjusting member 31 and the second adjusting member 32 move in the circumferential direction along the central axis Z, thereby driving the heating component 20 to move in the circumferential direction around the central axis Z, and further causing the accommodation space 20c formed by the heating component 20 to contract or expand.

[0045] The hot pressing device 100 provided in this embodiment enables the first adjusting member 31 and the second adjusting member 32, which are arranged at intervals, to simultaneously perform circumferential movement around the central axis Z under the action of the driving assembly 40. The first adjusting member 31 and the second adjusting member 32 simultaneously drive the second end 20b of the heating assembly 20 to move towards or away from the first end 20a of the heating assembly 20, which is beneficial to improving the stability of the process of tightening or expanding the accommodating space 20c, making the deformations at both ends of the accommodating space 20c on the central axis Z the same and ensuring consistency.

[0046] In some embodiments, a limiting member 16 is provided on one side of the first side plate 12 facing the second side plate 13. The limiting member 16 is used to limit the first adjusting member 31. When the first adjusting member 31 contacts the limiting member, the first adjusting member 31 drives the heating assembly 20 to fully expand. And / or, a limiting member 16 is provided on one side of the second side plate 13 facing the first side plate 12. The limiting member 16 is used to limit the second adjusting member 32. When the second adjusting member 32 contacts the limiting member 16, the second adjusting member 32 drives the heating assembly 20 to fully expand.

[0047] Please refer to Figures 2 to 5 , in a specific embodiment, the profiles of the first adjusting member 31 and the second adjusting member 32 are both arc-shaped, and the center of the arc formed by the profile of the first adjusting member 31 is located on the central axis Z, and the center of the arc formed by the profile of the second adjusting member 32 is located on the central axis Z.

[0048] For the hot pressing device 100 provided in this embodiment, since the profiles of the first adjusting member 31 and the second adjusting member 32 are both arc-shaped, and the centers of the arcs formed by the profiles of the first adjusting member 31 and the second adjusting member 32 are both located on the central axis Z, the trajectories of the driving assembly 40 driving the first adjusting member 31 and the second adjusting member 32 to perform circumferential movement along the central axis Z are both circular trajectories. Furthermore, the trajectory of the heating assembly 20 performing circumferential movement along the central axis Z is a cylindrical trajectory, which is convenient for the operator to control the degree of tightening or expanding of the heating assembly 20, and at the same time, the movement consistency of the heating assembly 20 is better.

[0049] Please refer to Figures 2 to 5 , in an embodiment, the adjusting assembly 30 further includes a connecting member 33. The connecting member 33 extends along the axial direction of the central axis Z, and both ends of the connecting member 33 in the axial direction of the central axis Z are fixedly connected to the first adjusting member 31 and the second adjusting member 32 respectively, so that the first adjusting member 31 and the second adjusting member 32 can move synchronously.

[0050] The hot pressing device 100 provided in this embodiment fixes and connects the first adjusting member 31 and the second adjusting member 32 through the connecting member 33, so that the driving assembly 40 can drive the first adjusting member 31 and the second adjusting member 32 to synchronously move circumferentially around the central axis Z, thereby making the heating assembly 20 have better consistency during the tightening or expansion process.

[0051] For the hot pressing device 100 provided in this embodiment, the number of the connecting members 33 is 3. The 3 connecting members 33 are sequentially arranged at intervals in the circumferential direction of the central axis Z and are connected between the first adjusting member 31 and the second adjusting member 32 through the 3 connecting members 33. The first adjusting member 31 and the second adjusting member 32 are connected as a whole, so that the movement processes of the first adjusting member 31 and the second adjusting member 32 are consistent, and the first adjusting member 31 and the second adjusting member 32 synchronously move circumferentially around the heating assembly 20, which is beneficial to making the heating assembly 20 more stable during the tightening and expansion processes.

[0052] It can be understood that in some other embodiments, the number of the connecting members 33 can be 1, 2, 4, 5, etc. Each connecting member 33 is connected between the first adjusting member 31 and the second adjusting member 32 to form the first adjusting member 31 and the second adjusting member 32 into a whole. The present application does not limit this. The connecting member 33 can be a connecting rod or other structures.

[0053] Please participate Figures 2 to 5 In one embodiment, the driving assembly 40 includes a driving member 41 and a transmission assembly 42. The driving member 41 is fixed to the housing 10. One end of the transmission assembly 42 in the axial direction of the central axis Z is transmission-connected between the output end of the driving member 41 and the first adjusting member 31, and the other end of the transmission assembly 42 in the axial direction of the central axis Z is connected to the second adjusting member 32. The output end of the driving member 41 drives the transmission assembly 42 to move, and then drives the first adjusting member 31 and the second adjusting member 32 to move.

[0054] For the hot pressing device 100 provided in this embodiment, one end of the transmission assembly 42 in the axial direction of the central axis Z is transmission-connected between the output end of the driving member 41 and the first adjusting member 31, and the other end of the transmission assembly 42 in the axial direction of the central axis Z is connected to the second adjusting member 32, so that the output end of the driving member 41 drives the transmission assembly 42 to move, and then drives the first adjusting member 31 and the second adjusting member 32 to act. The first adjusting member 31 and the second adjusting member 32 act to drive the heating assembly 20 to tighten or expand, so that the radial dimension of the accommodation space 20c can be reduced or increased, thereby enabling the heating assembly 20 to tightly wrap the workpieces to be processed with different shapes and sizes and perform hot pressing and transfer printing on the workpieces to be processed. In addition, the first adjusting member 31 and the second adjusting member 32 can be driven by one driving member 41.

[0055] Please participate Figures 2 to 5, in a specific embodiment, the driving member 41 includes a motor 411 and a mounting seat 412. One end of the mounting seat 412 is fixedly connected to the outer shell of the motor 411, and the other end of the mounting seat 412 is fixedly connected to the inner wall of the housing 10. In one embodiment, the mounting seat 412 can be U-shaped. The output end of the motor 411 is rotatably disposed in the U-shaped space formed by the mounting seat 412. The end where the opening of the mounting seat 412 is located is fixedly connected to the housing 10 by bolts, and the inner wall of the housing 10 covers the opening of the mounting seat 412.

[0056] Please participate Figures 2 to 5 , in a specific embodiment, the transmission assembly 42 includes a first transmission member 421, a second transmission member 422, and a linkage shaft 423. The linkage shaft 423 extends along the axial direction of the central axis Z. The first transmission member 421 and the second transmission member 422 are respectively fixed to opposite ends of the linkage shaft 423 in the axial direction of the central axis Z. The output end of the driving member 41 is connected to the first transmission member 421. The first transmission member 421 is in transmission connection with the first adjusting member 31, and the second transmission member 422 is in transmission connection with the second adjusting member 32. The driving member 41 drives the first transmission member 421 to rotate, thereby driving the linkage shaft 423 to rotate and the second transmission member 422 to rotate synchronously. Furthermore, it drives the first adjusting member 31 and the second adjusting member 32 to perform synchronous circumferential movement around the central axis Z, and further enables the opposite ends of the heating assembly 20 along the central axis Z to be synchronously tightened or expanded radially along the central axis Z, which is beneficial to improving the consistency of the heating assembly 20 during the tightening or expansion process.

[0057] In the hot pressing device 100 provided in this embodiment, the first transmission member 421 and the second transmission member 422 are respectively fixed to opposite ends of the linkage shaft 423 in the axial direction of the central axis Z. When the driving member 41 drives the first transmission member 421 to rotate, it can drive the linkage shaft 423 to rotate around its own axis, and then drive the second transmission member 422 to rotate. The first transmission member 421 is rotatably connected to the first adjusting member 31 so that the first adjusting member 31 can perform circumferential movement along the central axis Z. The second transmission member 422 is rotatably connected to the second adjusting member 32 so that the second adjusting member 32 can perform circumferential movement along the central axis Z. Moreover, the first transmission member 421 and the second transmission member 422 achieve synchronous rotation through the linkage shaft 423, so that the first adjusting member 31 and the second adjusting member 32 can perform synchronous circumferential movement around the central axis Z. Furthermore, when the second end 20b of the heating assembly 20 approaches or moves away from the first end 20a, the distance between the first end 20a and the second end 20b remains consistent in the circumferential direction of the central axis Z, so that when the heating assembly 20 tightens and wraps the workpiece to be processed, the force on the workpiece to be processed is more uniform, which is beneficial to improving the quality and effect of the hot pressing device 100 for performing heat transfer on the workpiece to be processed.

[0058] It can be understood that in some other embodiments, the number of driving members 41 can be two. One driving member 41 is used to drive the first transmission member 421 to move, and the other driving member 41 is used to drive the second transmission member 422 to move. It only needs to ensure that the driving parameters and working parameters of the two driving members 41 are the same, and the present application does not limit this.

The first transmission member 421 is rotationally connected to the driving member 41 through a gear. The first transmission member 421 is also rotationally connected to the first adjusting member 31 through a gear, so that the driving member 41 can drive the first adjusting member 31 to perform circumferential movement around the central axis Z through the first transmission member 421, and further enable the heating assembly 20 to contract or expand. The second transmission member 422 is a gear. The second transmission member 422 is fixedly connected to the first transmission member 421 through a linkage shaft 423. The driving member 41 drives the first transmission member 421, the linkage shaft 423, and the second transmission member 422 to rotate synchronously.

By connecting one end of the first elastic member 231 and the second elastic member 232 to the fixing member 22 and connecting the other ends of the first elastic member 231 and the second elastic member 232 to the intermediate rod 34, the elastic buffer between the fixing member 22 and the central rod can be made more uniform. Furthermore, the elastic buffer between the heating assembly 20 and the adjusting assembly 30 can be made more uniform, so that when the second end 20b of the flexible heating plate 21 moves in the circumferential direction of the central axis Z toward or away from the first end 20a, a gradually changing force can be more uniform, preventing the flexible heating plate 21 from being damaged due to a sudden force between the adjusting assembly 30 and the flexible heating plate 21, which is beneficial to improving the service life of the flexible heating plate 21 and the hot pressing device 100.
