Description

Technical Field

[0001] This application relates to the technical field of printers, and in particular to a thermal transfer printer. Background Technology

[0002] A thermal transfer printer is a printing device that uses heat to transfer images or text onto printing paper or other materials. It uses transfer paper and a printhead to achieve printing.

[0003] The main principle of a thermal transfer printer is that the printhead heats the ink on the transfer paper, causing it to melt and transfer to the target object. Many tiny dots on the printhead are heated, forming an image or text, and pressure is used to transfer the ink onto the printing paper or other material, ultimately completing the printing process.

[0004] During the operation of a thermal transfer printer, the heated ink remains molten for a period of time after being transferred to the printing paper. This molten ink can easily adhere to other objects that come into contact with the printing paper, resulting in blurry text or patterns on the printed paper. Summary of the Invention

[0005] To address the problem that ink on printed paper easily adheres to other objects after thermal transfer, resulting in blurred text or patterns on the printed paper, this application provides a thermal transfer printer.

[0006] The thermal transfer printer provided in this application adopts the following technical solution: A thermal transfer printer includes a frame, a printing material storage mechanism, a transport mechanism, a transfer mechanism, and an ink curing mechanism. The frame has an inlet end and an outlet end. The printing material storage mechanism is connected to the inlet end of the frame. One end of the transport mechanism is connected to the inlet end, and the other end of the transport mechanism is connected to the outlet end. The transfer mechanism is located between the inlet end and the outlet end and faces the transport mechanism. The ink curing mechanism is located on the side of the transfer mechanism away from the printing material storage mechanism. The ink curing mechanism includes a plurality of printheads facing the printing paper and a fan connected to the printheads.

[0007] By adopting the above technical solution, the transport mechanism feeds the printing paper from the infeed end into the printing material storage mechanism, which then passes through the transfer mechanism. The transfer mechanism transfers the text or pattern to be printed onto the printing paper. The printing paper then passes through the ink curing mechanism, where a fan provides airflow, causing the nozzles to spray air onto the printing paper, accelerating the cooling and curing of the ink. Finally, the transport mechanism removes the printing paper from the outlet end, completing the printing process. By incorporating the ink curing mechanism to accelerate the ink curing speed on the printing paper, the problem of ink adhering to other objects after heat transfer, resulting in blurred text or patterns, is solved.

[0008] Optionally, several of the printheads are symmetrically arranged opposite the printing paper being transported on the transport mechanism.

[0009] By adopting the above technical solution, the printheads are symmetrically arranged on both sides of the printing paper, which balances the forces on both sides of the printing paper, reduces the probability of the printing paper shaking, and thus reduces the probability of ink on the printing paper coming into contact with and adhering to other objects.

[0010] Optionally, the transport mechanism includes a first rolling group and a guide plate. The first rolling group is spaced apart and rotatably connected to the frame. The first rolling group is used to move the printing paper. The guide plate is fixedly connected to the frame and located between adjacent first rolling groups. The guide plate is used to guide the printing paper to move to the next first rolling group.

[0011] By adopting the above technical solution, the first roller and guide plate are used to transport the printing paper, reducing the contact area between the transport mechanism and the printing surface of the paper and enabling continuous transport of the printing paper. Furthermore, the transport speed of the printing paper can be adjusted by regulating the rotation speed of the roller, and the guide plate reduces the probability of the printing paper deviating from the transport path or folding during transport.

[0012] Optionally, the first rolling group includes a first roller and a second roller arranged in parallel. The two ends of the first roller are rotatably connected to the frame. One end of the first roller passes through the frame and is connected to a transmission belt. The transmission belt is connected to a drive shaft, and the drive shaft is connected to a drive motor.

[0013] By adopting the above technical solution, the rolling group formed by the two rollers ensures that the contact point between the printing paper and the rolling group is the generatrix of the rollers, thereby reducing the contact area between the printing surface of the printing paper and the transport mechanism. The drive motor rotates the transmission belt, achieving synchronous rotation of all the first rollers, reducing the probability of paper folding, and the fact that only the first rollers move the printing paper also reduces power loss.

[0014] Optionally, the transport mechanism further includes a curing section, which includes a second rolling group and guide members arranged vertically. The second rolling group has the same structure as the first rolling group. One end of the second roller passes through the frame and is connected to the transmission belt. Two sets of guide members are arranged between adjacent second rolling groups. A curing gap is provided between the two sets of guide members. The nozzles are symmetrically distributed between the curing gaps.

[0015] By adopting the above technical solution, the second rolling group of the curing section provides the transport power for the printing paper in the curing section, and the guiding components reduce the probability of the printing paper deviating from the transport direction in the curing section. The two sets of guiding components further reduce the probability of the printing paper deviating from the transport direction. The curing gap facilitates the nozzle to spray air onto the printing paper from both sides simultaneously, accelerating the curing speed of the ink on the printing paper.

[0016] Optionally, the guiding component includes a first guide plate and a second guide plate arranged in parallel at intervals, both of which are connected to the frame.

[0017] By adopting the above technical solution, the printing paper is sandwiched between the first guide plate and the second guide plate to realize the transportation of the printing paper, thereby reducing the probability that the printing paper will be blown away from the transportation route by the gas blown out of the nozzle.

[0018] Optionally, the first guide plate is provided with a first guide plate at one end facing the previous second rolling group, and the first guide plate is inclined upward in the direction away from the second guide plate. The second guide plate is provided with a second guide plate at one end facing the previous second rolling group, and the second guide plate is inclined upward in the direction away from the first guide plate.

[0019] By adopting the above technical solution, when the printing paper deviates from the transport direction by a certain range, the first guide plate or the second guide plate can block the printing paper, so that the printing paper returns to the normal transport route, thereby reducing the probability of the printing paper deviating from the transport route.

[0020] Optionally, the transfer mechanism includes a transfer roller, a base, and a print head. The transfer roller is fixedly connected to the frame and disposed on the side of the ink curing mechanism near the feed end. The transfer roller is located between the first rolling group and the second rolling group. The base is slidably connected to the frame. The lower end face of the frame can abut against the transfer roller. The print head is fixedly connected to the base and can abut against the transfer paper. Both the printing paper and the transfer paper are located between the transfer roller and the frame.

[0021] By adopting the above technical solution, when the printer is working, the print head melts the ink on the transfer paper, and then the transfer roller presses the melted ink on the transfer paper onto the printing paper to achieve thermal transfer printing. The transfer roller is set on the side of the ink curing mechanism near the feed end and between the first roller and the second roller, so that the printing paper immediately enters the ink curing mechanism for curing after printing. This reduces the probability of uncured ink on the printing paper coming into contact with other objects, shortens the time of ink melting, and reduces the probability of ink on the printing paper adhering to other objects.

[0022] Optionally, the thermal transfer printer further includes a cutting mechanism, which is fixedly connected to the frame and located at the discharge end. The cutting mechanism includes a moving device and a cutting blade. The moving device is slidably connected to the frame, and the sliding direction of the moving device is perpendicular to the moving direction of the printing paper. The end of the moving device facing the transport mechanism is connected to the cutting blade. The moving range of the moving device exceeds the width of the printing paper by at least the width of the cutting blade. The cutting range of the cutting blade includes the moving plane where the printing paper is located.

[0023] By adopting the above technical solution, the cutting mechanism is set at the discharge end, which can cut the printing paper as needed. When the printing paper does not need to be cut, the cutting blade moves to the side of the printing paper. When the printing paper needs to be cut, the cutting blade moves along the direction perpendicular to the movement of the printing paper to cut the printing paper.

[0024] Optionally, the thermal transfer printer further includes a waste paper recycling mechanism, which is connected to the frame and located at the end of the printing material storage mechanism near the discharge end. The printing material storage mechanism and the waste paper recycling mechanism are connected through the transport mechanism.

[0025] By adopting the above technical solution, the waste paper recycling organization collects the printed transfer paper, and after printing all the paper, the waste transfer paper is taken out at once, eliminating the need to frequently process the printed transfer paper and making the use of the printer more convenient.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the printer transfers the ink from the transfer paper to the printing paper, the nozzle in the ink curing mechanism blows air onto the molten ink on the printing paper to accelerate the curing speed of the molten ink on the printing paper. This achieves rapid curing of the ink on the printing paper and reduces the probability of the molten ink on the printing paper coming into contact with other objects. This solves the problem that the ink on the printing paper is easy to stick to other objects after heat transfer, resulting in blurry text or patterns on the printing paper. 2. By placing the nozzles in the curing gap and positioning them on both sides of the printing paper while blowing air onto the paper, the curing speed of the ink on the printing paper is increased, and the probability of ink adhering to other objects and causing the text or patterns on the printing paper to become blurred is reduced. 3. A curing section is set up in the transport mechanism. The upper and lower curing sections improve the utilization of printer space. The first guide plate and the second guide plate in the curing section clamp the printing paper and reduce the probability of the printing paper being blown away from the transport route by the print head.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a thermal transfer printer. (Refer to...) Figure 1 and Figure 2A thermal transfer printer includes a frame 1, a printing material storage mechanism 2, a transport mechanism 3, a transfer mechanism 4, and an ink curing mechanism 5. The frame 1 has an infeed end 11 and an outlet end 12 at both ends. The transport mechanism 3 is located inside the frame 1 and connects the infeed end 11 and the outlet end 12. The printing material storage mechanism 2 is fixedly connected to the infeed end 11 of the frame 1 and connected to the transport mechanism 3. The transfer mechanism 4 is fixedly connected to the frame 1 and located above the transport mechanism 3. The ink curing mechanism 5 is fixedly connected to the frame 1 and located between the transfer mechanism 4 and the outlet end 12. The ink curing mechanism 5 includes a printhead 51 fixedly connected to the frame 1 and a fan 52 communicating with the printhead 51. The printhead 51 blows air toward the printing paper 6 on the transport mechanism 3.

[0035] Before printing with the thermal transfer printer, the transfer paper 9 is rolled into the printing material storage mechanism 2. At the start of printing, the printing paper 6 is placed onto the transport mechanism 3 through the feed end 11. The transport mechanism 3 simultaneously transports the printing paper 6 and the transfer paper 9 located in the printing material storage mechanism 2 to the bottom of the transfer mechanism 4. The transfer mechanism 4 then prints the desired text and patterns. After printing, the used transfer paper 9 is removed from the transport mechanism 3, and the printed paper 6 is transported to the ink curing mechanism 5. The fan 52 provides airflow to the nozzle 51, which blows air onto the molten ink on the printing paper 6, accelerating the curing of the molten ink and preventing ink from adhering to other objects, thus solving the problem of ink adhering to other objects after thermal transfer, causing blurry text or patterns on the printing paper.

[0036] Reference Figure 1 The printing material storage mechanism 2 includes a first roller 21 and a first rotating shaft 22 coaxially rotatably connected. A first storage cavity 23 is formed between the first rotating shaft 22 and the first roller 21. The transfer paper 9 is stored in the first storage cavity 23. An outlet 211 is formed on the side wall of the first roller 21, which is connected to a transport mechanism 3. The transfer paper 9 can be transported out of the printing material storage mechanism 2 through the outlet 211. The upper and lower halves of the first roller 21 are hinged, and the lower half of the first roller 21 is fixedly connected to the frame 1. When inserting the transfer paper 9, the upper half of the first roller 21 can be opened by the hinge to insert the transfer paper 9.

[0037] Reference Figure 1The transport mechanism 3 includes a first rolling group 31 and a guide plate 32, which are spaced apart. The first rolling group 31 provides the power for transporting the printing paper 6, and the guide plate 32 reduces the probability of the printing paper 6 deviating from the transport route. The first rolling group 31 consists of a first roller 311 and a second roller 312 arranged in parallel. The side walls of the first roller 311 and the second roller 312 abut against each other, and both the first roller 311 and the second roller 312 are rotatably connected to the frame 1. During transport, the printing paper 6 is transported from the connection between the first roller 311 and the second roller 312 to the upper surface of the guide plate 32, and then enters the connection between the first roller 311 and the second roller 312 of the next first rolling group 31 from the upper surface of the guide plate 32, thus realizing the transport of the printing paper 6.

[0038] Reference Figure 3 and Figure 4 One end of the first roller 311 is connected to a transmission belt 33, which is connected to one end of all the first rollers 311. The transmission belt 33 is connected to a drive shaft 35, and the end of the drive shaft 35 facing away from the transmission belt 33 is connected to a drive motor 34 via a belt. The drive motor 34 drives the drive shaft 35 to rotate, which in turn moves the transmission belt 33, thereby driving the first rollers 311 and ultimately driving the printing paper 6 and the transfer paper 9.

[0039] Reference Figure 1 and Figure 5 The transfer mechanism 4 includes a base 42, a transfer roller 41, and a print head 43. The base 42 is slidably connected to the frame 1. The transfer roller 41 is fixedly connected to the frame 1 and located on one side of the first rolling group 31, abutting against the guide plate 32. The base 42 can move downward so that its lower end face abuts against the transfer roller 41. The print head 43 is fixedly connected to the lower end face of the base 42. Before printing, the transport mechanism 3 transports the transfer paper 9 in the printing material storage mechanism 2 together with the printing paper 6 to the space between the transfer roller 41 and the base 42. During printing, the base 42 moves down so that the print head 43 comes into contact with the transfer paper 9. The print head 43 heats the corresponding part of the transfer paper 9 according to the text or graphics to be printed, so as to melt the ink on the corresponding part of the transfer paper 9. Then, the printing paper 6 and the transfer paper 9 are transported together to the top of the transfer roller 41. The base 42 moves down and abuts against the transfer roller 41. The transfer paper 9 is squeezed by the transfer roller 41, so that the melted ink on the transfer paper 9 is transferred to the printing paper 6 to complete the printing.

[0040] Reference Figure 1The transfer mechanism 4 has a waste paper recycling mechanism 8 connected to the frame 1 on the side near the discharge end 12. The waste paper recycling mechanism 8 includes a second roller 81 and a second rotating shaft 82. The second roller 81 and the second rotating shaft 82 are coaxially connected, and a second storage cavity 83 is opened between the second roller 81 and the second rotating shaft 82. The printed transfer paper 9 is stored in the second storage cavity 83. The upper and lower halves of the second roller 81 are connected by a hinge. The lower half of the second roller 81 is fixedly connected to the frame 1. The second roller 81 has a recycling port 811 for recycling the transfer paper 9, which faces the transport mechanism 3. When recycling the printed transfer paper 9, the transfer paper 9 enters the waste paper recycling mechanism 8 through the recycling port 811 and is rolled into a paper roll by the second rotating shaft 82. After printing, the upper half of the second roller 81 can be opened to remove the transfer paper 9, eliminating the need for frequent processing of the printed transfer paper 9 and facilitating the use of the printer.

[0041] Reference Figure 1 and Figure 2 The transport mechanism 3 also includes a curing section 36, which is located on the side of the transfer mechanism 4 near the discharge end 12. The curing section 36 includes a second rolling group 361 and a guide member 362. The second rolling group 361 is arranged vertically, and two vertically arranged guide members 362 are arranged between two adjacent second rolling groups 361. The two vertically arranged guide members 362 reduce the probability of the printing paper 6 deviating from the transport direction when transported downward.

[0042] Reference Figure 2 The guiding component 362 includes a first guide plate 3621 and a second guide plate 3622, which are arranged vertically and parallel to each other. The gap between the first guide plate 3621 and the second guide plate 3622 is used to transport the printing paper 6. The gap between the first guide plate 3621 and the second guide plate 3622 clamps the printing paper 6, reducing the probability that the printing paper 6 will be blown away from the transport route by the air blown by the nozzle 51. A first guide plate 3623 is fixedly connected to the upper end face of the first guide plate 3621, and the first guide plate 3623 is inclined upwards in a direction away from the second guide plate 3622. A second guide plate 3624 is fixedly connected to the upper end face of the second guide plate 3622, and the second guide plate 3624 is inclined upwards in a direction away from the first guide plate 3621. When the printing paper 6 deviates from the transport direction by a certain angle, it can be blocked by the inclined first guide plate 3623 or the second guide plate 3624, thus returning it to the normal transport route.

[0043] Reference Figure 1A thermal transfer printer also includes a cutting mechanism 7, which is slidably connected to the discharge end 12 of the frame 1. The cutting mechanism 7 includes a moving device 71 and a cutting blade 72. The moving device 71 is slidably connected to the frame 1 in the direction perpendicular to the movement of the printing paper 6. The moving device 71 is located above the transport mechanism 3. The cutting blade 72 is fixedly connected below the moving device 71. The range of movement of the moving device 71 exceeds the width of the printing paper 6 by the distance of one cutting blade 72. The cutting range of the cutting blade 72 includes the plane where the printing paper 6 is located.

[0044] When not cutting, the cutting blade 72 is located on the side of the printing paper 6 and does not contact the printing paper 6. When it is necessary to cut the printing paper 6, the first roller 311 controls the printing paper 6 to stop moving, and the cutting blade 72 moves in a direction perpendicular to the movement of the printing paper 6 to cut the printing paper 6. After the cutting is completed, the cutting blade 72 returns to its original position to facilitate the next cutting.

[0045] The implementation principle of a thermal transfer printer according to an embodiment of this application is as follows: First, printing paper 6 is placed into the printer from the feed end 11 of the frame 1. The transport mechanism 3 transports the printing paper 6 to the thermal transfer mechanism 4, and simultaneously, the transfer paper 9 in the printing material storage mechanism 2 is transported from above the printing paper 6 to the thermal transfer mechanism 4. Next, the print head 43 in the thermal transfer mechanism 4 melts the ink on the corresponding part of the transfer paper 9, and then the transfer roller 41 presses the ink on the transfer paper 9 onto the printing paper 6 to achieve the printing of text or patterns. After the printer prints the text or pattern on the printing paper 6, the printing paper 6 continues to be transported by the transport mechanism 3 to the ink curing mechanism 5. The nozzle 51 in the ink curing mechanism 5 accelerates the curing of the melted ink on the printing paper 6. Finally, the cured printing paper 6 is discharged from the discharge end 12 of the frame 1. If it is necessary to cut the printing paper 6, it can also be cut by the cutting mechanism 7 of the discharge end 12. By setting up the ink curing mechanism 5, the probability of the molten ink on the printing paper 6 coming into contact with other objects is reduced, thereby solving the problem that the ink on the printing paper is easy to stick to other objects after heat transfer, resulting in blurry text or patterns on the printing paper.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
