[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Please refer to Figures 1-4 This application provides a self-cleaning sublimation transfer film winding device, comprising:

[0042] The box body 1 has a processing space inside. The box body 1 has an inlet 2 and an outlet 3 communicating with the processing space. The outer side of the box body 1 is provided with an unwinding roller 4 and a winding roller 5 corresponding to the inlet 2 and the outlet 3, respectively.

[0043] A cleaning component is disposed within the processing space. The cleaning component includes two adsorption units. The two adsorption units are arranged along the transport direction of the transfer film 6 and can work simultaneously or independently. Each adsorption unit includes a first state for dust adsorption and a second state for backflushing self-cleaning.

[0044] An antistatic component is provided on the transfer film 6 transport path between the roll inlet 2 and the cleaning component.

[0045] The tensioning component is located on the transfer film 6 transport path between the cleaning component and the roll outlet 3.

[0046] Specifically, the housing 1 is constructed from welded metal sheets, forming a closed processing space inside. This provides an independent environment for the cleaning and transport of the transfer film 6, reducing secondary pollution from external dust. An inlet 2 is located on one side wall of the housing 1, and an outlet 3 is located on the opposite side wall. The openings of these two openings are adapted to the transport path of the transfer film 6, ensuring smooth passage. On the outside of the housing 1, an unwinding roller 4 is installed corresponding to the inlet 2. The unwinding roller 4 is fixed by a bracket and supports the roll of transfer film 6 to be unwound. A motor drives the unwinding at a uniform speed. A take-up roller 5 is installed corresponding to the outlet 3. The take-up roller 5 is driven by a motor to rotate and wind the processed transfer film 6 into a neat roll.

[0047] The cleaning assembly is located within the processing space of housing 1, in the middle of the transport path of transfer film 6. This cleaning assembly consists of two adsorption units arranged sequentially along the transport direction of transfer film 6, with a certain distance between them. Each adsorption unit can independently switch its operating state: in the first state, it removes dust, debris, and other impurities from the surface of transfer film 6 through airflow adsorption; in the second state, it discharges accumulated impurities from inside the adsorption unit through reverse airflow, achieving self-cleaning. Both adsorption units can be in the first state simultaneously to enhance the cleaning effect, or one can be in the first state while the other is in the second state, ensuring uninterrupted cleaning.

[0048] An electrostatic elimination component is installed on the transport path of the transfer film 6 between the inlet 2 and the cleaning component. It is used to eliminate static electricity on the surface of the transfer film 6 before it enters the cleaning component. Since the transfer film 6 is prone to generating static electricity due to friction during unwinding and transport, static electricity will attract dust from the surrounding environment, increasing the difficulty of cleaning. The electrostatic elimination component can reduce the electrostatic attraction of the transfer film 6 by neutralizing the charge, making subsequent cleaning more thorough.

[0049] The tensioning assembly is positioned on the transport path of the transfer film 6 between the cleaning assembly and the exit vent 3, and is used to adjust the tension of the transfer film 6 during transport. By maintaining a stable tension, it ensures that the transfer film 6 remains flat as it passes through the cleaning assembly, ensuring full contact with the cleaning components and improving the cleaning effect; at the same time, it avoids stretching and deformation of the transfer film 6 due to excessive tension, or wrinkles on the film surface due to insufficient tension, ensuring that the rolled-up transfer film is tight and neat.

[0050] Furthermore, the adsorption unit includes two cleaning tubes 7, which are arranged in a direction perpendicular to the top surface of the housing 1 and are positioned opposite each other, with the transfer film 6 passing between the two cleaning tubes 7;

[0051] The cleaning fitting 7 includes:

[0052] Cleaning pipe 8, one end of which is connected to a ventilation source device and a first dust collection bag, and the other end is provided with an air outlet 9;

[0053] Self-cleaning pipe 10, one end of which is connected to the cleaning pipe 8, and the other end of which is connected to the second dust collection bag;

[0054] A switching mechanism is provided for switching the cleaning unit between a first state and a second state; in the first state, the air vent 9 is open and the self-cleaning pipe 10 is closed; in the second state, the air vent 9 is closed and the self-cleaning pipe 10 is open.

[0055] Specifically, each adsorption unit achieves the cleaning function of the transfer film 6 and its own cleaning function through the synergistic action of two cleaning tubes 7. The two cleaning tubes 7 are arranged vertically opposite each other with their openings facing each other, forming a gap between them for the transfer film 6 to pass through horizontally. The size of the gap is preset according to the thickness of the transfer film 6 to ensure that the upper and lower surfaces of the transfer film 6 can maintain the optimal working distance with the cleaning tubes 7 when passing through.

[0056] The cleaning pipe 7 completes the state switching through the cooperation of the cleaning pipe 8, the self-cleaning pipe 10 and the switching mechanism: one end of the cleaning pipe 8 is connected to the ventilation source device and the first dust collection bag through a flexible pipe, and the air outlet 9 at the other end is facing the surface of the transfer film 6. The length of the air outlet 9 matches the width of the transfer film 6 and can fully cover the film surface; one end of the self-cleaning pipe 10 is connected to the middle of the cleaning pipe 8, and the other end is connected to the second dust collection bag through a flexible pipe, forming an independent impurity discharge channel. When the adsorption unit is in the first state, the switching mechanism keeps the air vent 9 open while simultaneously closing the self-cleaning pipe 10. At this time, the negative pressure generated by the air source device acts on the air vent 9 through the cleaning pipe 8. Dust on the surface of the transfer film 6 is carried by the airflow through the air vent 9 into the cleaning pipe 8, and is eventually collected by the first dust collection bag, thus cleaning the transfer film 6. When the adsorption unit needs to switch to the second state, the switching mechanism operates synchronously, closing the air vent 9 and opening the self-cleaning pipe 10. The air source device switches to positive pressure output, and the high-pressure airflow flows in the opposite direction along the cleaning pipe 8, blowing the residual dust adhering to the inner wall of the pipe and the air vent 9 into the self-cleaning pipe 10, where it is collected by the second dust collection bag, completing the self-cleaning of the cleaning pipe 7. The air source device, the first dust collection bag, and the second dust collection bag are located on the outside of the housing 1. A unidirectional ventilation structure can be installed on the first and second dust collection bags to prevent dust leakage and secondary pollution.

[0057] Furthermore, the switching mechanism includes:

[0058] A first rotating baffle 11 is disposed at the connection position of the cleaning pipeline 8 and the self-cleaning pipeline 10. The first rotating baffle 11 is driven by the first driving device 12 to open or close the self-cleaning pipeline 10.

[0059] The second rotating baffle 13 is located at the air vent 9 and is driven by the second driving device 14 to open or close the air vent 9.

[0060] Specifically, the first rotating baffle 11 is installed at the connection position between the cleaning pipe 8 and the self-cleaning pipe 10. Its size is adapted to the interface size and can be driven to rotate by the first driving device 12. The second rotating baffle 13 is set at the air outlet 9 and has a sealing structure on the edge. Its rotation is controlled by the second driving device 14. When the adsorption unit is in the first state, the first driving device 12 drives the first rotating baffle 11 to rotate to the position of closing the self-cleaning pipeline 10, while the second driving device 14 drives the second rotating baffle 13 to rotate to open the air outlet 9, so that the cleaning pipeline 8 forms a complete airflow channel from the air outlet 9 to the air source device and the first dust collection bag, and the dust on the surface of the transfer film 6 can be successfully adsorbed and collected. When switching to the second state, the first driving device 12 drives the first rotating baffle 11 to rotate to open the self-cleaning pipeline 10, while the second driving device 14 drives the second rotating baffle 13 to rotate to close the air outlet 9. At this time, the cleaning pipeline 8 is connected to the self-cleaning pipeline 10, and the back-blowing airflow output by the air source device can send the residual impurities in the pipeline into the second dust collection bag through the self-cleaning pipeline 10 to complete the self-cleaning.

[0061] Furthermore, the heat sublimation transfer film winding device with self-cleaning function is characterized in that a filter screen 15 is connected to the first rotating baffle 11, and when the first rotating baffle 11 closes the self-cleaning pipeline 10, the filter screen 15 is placed in the cleaning pipeline 8; when the first rotating baffle 11 opens the self-cleaning pipeline 10, the filter screen 15 is placed in the self-cleaning pipeline 10.

[0062] Specifically, a filter screen 15 is fixedly connected to one side surface of the first rotating baffle 11. The filter screen 15 is made of high-density nylon mesh or metal mesh, and its size is adapted to the inner diameter of the cleaning pipe 8, so as to completely cover the cross-section of the pipe. When the adsorption unit is in the first state, the first driving device 12 drives the first rotating baffle 11 to rotate to the position of closing the self-cleaning pipe 10. At this time, the filter screen 15 rotates into the cleaning pipe 8 along with the baffle, and is exactly in the airflow channel. After the dust on the surface of the transfer film 6 enters the cleaning pipe 8 through the air outlet 9, the small-diameter dust will enter the first dust collection bag through the filter screen 15, while the large-diameter dust will be intercepted and filtered by the filter screen 15 to avoid clogging of the cleaning pipe 8 and ensure stable adsorption force.

[0063] When the adsorption unit switches to the second state, the first drive device 12 drives the first rotating baffle 11 to rotate to open the self-cleaning pipeline 10. The filter screen 15 is transferred to the inlet of the self-cleaning pipeline 10 along with the baffle. At this time, the back-blowing airflow flows along the cleaning pipeline 8, blowing the large-particle dust attached to the filter screen 15 and the residual impurities on the inner wall of the pipeline into the self-cleaning pipeline 10. The filter screen 15 can filter the impurities in the back-blowing airflow for the second time in the self-cleaning pipeline 10, ensuring that the impurities that finally enter the second dust collection bag are completely collected and preventing the leakage of impurities during the back-blowing process.

[0064] Furthermore, the adsorption unit further includes an adjustment component, the adjustment component comprising:

[0065] The first slide rail 16 extends in a direction perpendicular to the top surface of the housing 1;

[0066] The first slider 17 is slidably mounted on the first slide rail 16 and connected to the cleaning pipe 7 near the top surface of the housing 1.

[0067] Specifically, the adjustment component of the adsorption unit is used to flexibly adjust the spacing between the two cleaning tubes 7 according to the thickness of the transfer film 6, so as to ensure a balance between cleaning effect and film surface protection. The adjustment function is achieved by the cooperation of the first slide rail 16 and the first slider 17. The first slide rail 16 extends along the direction perpendicular to the top surface of the box 1 and is fixed to the inner wall of the box 1, providing a stable guide path for the adjustment action; the first slider 17 is slidably mounted on the first slide rail 16 and is fixedly connected to the cleaning tube 7 near the top surface of the box 1, forming a synchronous movement structure. When the spacing needs to be adjusted, by driving the first slider 17 to slide along the first slide rail 16, the upper cleaning tube 7 can be moved closer to or away from the lower cleaning tube 7, thereby changing the channel width for the transfer film 6 to pass through between the two, until it is adapted to the thickness of the transfer film 6 being processed, ensuring that the transfer film 6 can pass smoothly and the surface maintains the optimal adsorption distance with the cleaning tube 7. After the adjustment is completed, the first slider 17 can be fixed on the slide rail by the locking structure to maintain the spacing stability.

[0068] Furthermore, the cleaning assembly also includes a vibrating roller 18 disposed between the two adsorption units.

[0069] Specifically, the vibrating roller 18 is integrally mounted within the processing space of the housing 1, with its axis parallel to the width direction of the transfer film 6, and its roller surface in contact with the surface of the transfer film 6. Under the action of the driving device, the vibrating roller 18 generates minute vibrations at a preset frequency and transmits these vibrations to the surface of the transfer film 6. This vibration loosens firmly attached dust and debris on the transfer film 6, improving cleaning efficiency.

[0070] Furthermore, the static elimination component includes:

[0071] A pair of ion air plates 19 are respectively disposed on the side of the inlet 2 near the top surface of the box 1 and the side away from the top surface of the box 1. The ion air plates 19 are used to release positive and negative charges to the transfer film 6.

[0072] Ion roller 20 is located on the side of the ion air plate 19 away from the inlet 2 and is grounded.

[0073] Specifically, a pair of ion air plates 19 are located on the upper and lower sides of the transfer film 6, that is, on the side closer to the top surface of the box 1 and on the side farther away from the top surface of the box 1. When they are working, they release positive and negative charges to the surface of the transfer film 6 to neutralize the static electricity generated by friction of the transfer film 6. The ion roller 20 is set on the side of the ion air plate 19 away from the inlet 2, and is in contact with the surface of the transfer film 6 and grounded, so that the residual charge on the surface of the transfer film 6 can be conducted away through the grounding line.

[0074] Furthermore, the tensioning assembly includes:

[0075] Two support rollers 21 are arranged in a direction parallel to the top surface of the housing 1;

[0076] The swing device 22 has a tension adjusting roller 24 installed at the free end of the swing arm 23, and the tension adjusting roller 24 is placed between the two support rollers 21.

[0077] Support arm 25, one end of which is hinged to the free end of swing arm 23, and the other end is slidably connected to the bottom of box 1.

[0078] Specifically, two support rollers 21 are arranged parallel to the top surface of the housing 1 to provide transport support for the transfer film 6. A tension adjusting roller 24 is installed at the free end of the swing arm 23 of the swing device 22. This tension adjusting roller 24 is positioned between the two support rollers 21 and contacts the lower surface of the transfer film 6. After being output from the cleaning assembly, the transfer film 6 passes sequentially around the two support rollers 21 and the tension adjusting roller 24, forming a zigzag transport path. One end of the support arm 25 is hinged to the free end of the swing arm 23, and the other end is slidably connected to the bottom of the housing 1 via a second slide rail 30 and a second slider 31, forming auxiliary support for the swing arm 23. When the tension of the transfer film 6 changes, the swing device 22 drives the swing arm 23 to swing the tension adjusting roller 24 up and down, adjusting the tension by changing the pressure of the tension adjusting roller 24 on the transfer film 6. The support arm 25 slides at the bottom of the housing 1 as the swing arm 23 swings, helping to maintain the stable posture of the swing arm 23 and ensuring that the transfer film 6 maintains a preset tension range during transport.

[0079] Furthermore, a tension sensor 26 is mounted on the swing arm 23 and is connected to the support arm 25 via a connecting rope 27.

[0080] Specifically, the tension sensor 26 is mounted on the swing arm 23 of the tensioning assembly, and is connected to the support arm 25 via a connecting rope 27, forming a real-time monitoring structure for the tension of the transfer film 6. When the tension of the transfer film 6 changes, the swing arm 23 drives the tension adjusting roller 24 to swing, and the support arm 25 slides at the bottom of the housing 1 as the swing arm 23 moves. At this time, the connecting rope 27 will generate tension on the tension sensor 26. The tension sensor 26 converts the sensed tension signal into an electrical signal and transmits it to the control system. The control system determines the real-time tension state of the transfer film 6 based on the signal and drives the swing device 22 to adjust the swing angle of the swing arm 23. Then, the tension of the transfer film 6 is precisely controlled by the tension adjusting roller 24 to keep the tension within the preset range.

[0081] Furthermore, a hinged door 28 is provided on one side of the housing 1.

[0082] Specifically, a hinged cover 28 is provided on one side of the housing 1. This cover 28 is connected to the side wall of the housing 1 via a hinge and is equipped with a locking structure. When closed, it forms a sealed state with the housing 1, and when opened, it exposes the processing space inside the housing 1. When it is necessary to inspect, maintain, or replace components such as cleaning components, static elimination components, and tensioning components inside the housing 1, the cover 28 can be opened to directly access the internal structure. During normal operation, the cover 28 is kept closed to ensure the airtightness of the processing space and prevent external dust from entering or internal airflow from leaking out.

[0083] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed.
