Description

Technical Field

[0001] The invention belongs to the field of transfer paper processing, and more specifically, relates to a production process of inkjet thermal transfer paper. Background Art

[0002] Transfer paper production utilizes the sublimation characteristics of disperse dyes. Disperse dyes with a molecular weight of 250-400 and a particle diameter of 0.2-2 microns are used with water-soluble carriers (such as sodium alginate) or alcohol-soluble carriers (such as ethyl cellulose) and oil-soluble resins to make ink. The ink is processed on a transfer printing machine at 200-230°C for 20-30 seconds to transfer the disperse dyes to synthetic fibers such as polyester and fix them.

[0003] The existing equipment heats the transfer paper through a whole heating platform, while the blank section between two patterns on the transfer paper does not need to be heated, resulting in a waste of heat. In addition, during the heating process, the equipment only fixes the left and right ends of the transfer paper. Due to the thermal expansion and contraction, the middle part of the transfer paper will bulge or wrinkle, which will cause the pattern to deform and affect the product quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a production process for inkjet thermal transfer paper, which can fix each pattern separately and heat only the pattern area.

[0005] The invention discloses a production process for inkjet thermal transfer paper, in which patterns are evenly distributed on the transfer paper, and a blank section is formed between two patterns; the length of the diamond telescopic frame is adjusted according to the size of the pattern, so that the spacing between two adjacent pressing units is equal to the spacing between the two blank sections; the spacing of the push frames is adjusted so that the push frames face the corresponding number of heating strips, and at this time, the overall spacing of the heating strips corresponding to the push frames is equivalent to the width of the pattern.

[0006] The transfer paper is fed into the base, and the press unit is located just above each blank segment.

[0007] The pressing unit moves downward and abuts against the blank section; the push frame drives the corresponding heating strip to move upward and abuts against the transfer paper opposite to the pattern; the pressing unit generates pressure on the transfer paper, so that the transfer paper and the heating strip are pressed tightly, and the pattern and the heating strip are tightly attached together.

[0008] The heating strip works to heat the pattern.

[0009] As a further improvement of the present invention, it also includes a base, a feeding mechanism arranged on the base to drive the transfer paper to move left and right, a heating platform arranged below the transfer paper, and a lifting mechanism for pressing the transfer paper against the heating platform; the lifting mechanism includes a lifting plate that slides longitudinally above the base and a diamond-shaped telescopic frame that extends and retracts along the left and right directions; the diamond-shaped telescopic frame is evenly equipped with downward pressing units along the left and right directions; when the diamond-shaped telescopic frame drives the downward pressing units to move, the spacing between the downward pressing units is always equal; through the extension and retraction of the diamond-shaped telescopic frame, the downward pressing units are directly opposite to the blank sections.

[0010] As a further improvement of the present invention, the heating platform includes a plurality of heating bars closely arranged along the left-right direction; each heating bar slides longitudinally on the base; the heating bars penetrate the transfer paper in the front-to-back direction; when the pressing unit presses against the blank section, only the heating bars located below the pattern move upward until they are pressed against the transfer paper.

[0011] As a further improvement of the present invention, the pressing unit includes a pressing plate connected to a diamond-shaped telescopic frame and a lifting frame longitudinally sliding on the pressing plate; a pushing frame located below the heating table is arranged between the lifting frames in two adjacent pressing units; the pushing frame includes two pushing plates connected for relative rotation; one pushing plate is rotatably connected to one lifting frame.

[0012] As a further improvement of the present invention, a sliding rod slidably connected to the lifting frame is provided on the pressure plate; the pressing unit also includes a rocker arm rotatably connected to the sliding rod and located below the lifting frame; the rotating shaft of the rocker arm is arranged in a horizontal direction; the side of the rocker arm away from the rotating shaft of the rocker arm is abutted against the lower end of the lifting frame; a supporting rod in contact with the rocker arm is provided on the base below the rocker arm; when the pressure plate moves downward, the rocker arm pushes the lifting frame to move upward.

[0013] As a further improvement of the present invention, each of the heating strips is provided with a conductive column; a power rail is fixedly connected inside the base; when the push frame drives the heating strip to move upward until it abuts against the transfer paper, the conductive column is connected to the power rail.

[0014] As a further improvement of the present invention, the diamond-shaped telescopic frame includes a plurality of connecting plate groups that are rotatably connected together in sequence; the connecting plate group includes two connecting plates that are rotatably connected together; a center hole is provided in the middle of the connecting plate; the two connecting plates in the connecting plate group are rotatably connected together through the center hole; side holes are respectively provided on both sides of the connecting plate; the side holes between two adjacent connecting plate groups are rotatably connected; a connecting column is provided on the upper end of the pressure plate; the connecting column is rotatably connected to the center hole.

[0015] As a further improvement of the present invention, the lifting plate is rotatably connected to an adjusting screw arranged along the left and right directions of the rotating shaft; the outer wall of the adjusting screw is provided with two sections of thread grooves with opposite rotation directions; the two center holes on both sides of the diamond-shaped telescopic frame along the left and right directions are respectively connected with connecting sleeves that rotate coaxially; a connecting sleeve is transmission-connected to a thread groove; an adjusting motor that drives the adjusting screw to rotate is fixedly connected to the lifting plate.

[0016] As a further improvement of the present invention, the base is rotatably connected to a plurality of lifting screws longitudinally arranged with rotating shafts; the lifting plate is provided with a threaded sleeve transmission connected to the lifting screws; the various lifting screws are connected through a synchronous belt transmission; and a lifting motor is fixedly connected to the base for driving a lifting screw to rotate.

[0017] As a further improvement of the present invention, the feeding mechanism includes two tangential feeding wheels and a feeding motor driving the feeding wheels to rotate; and the transfer paper is located between the two feeding wheels.

[0018] Compared with the prior art, the beneficial effect of the present invention is that when the patterns on the transfer paper are of different sizes, the present invention adjusts the diamond-shaped telescopic frame to change the spacing between the pressing units, so that the pressing units are directly opposite to the blank section, and there is a pattern between the two pressing units. And by changing the width of the push frame in the left and right directions, the push frame only pushes the heating strip directly below the pattern to move. Finally, for each pattern, the pressing plates on both sides of the pattern make the pattern tightly attached to the heating strip, ensuring that the pattern will not wrinkle during the heating process and avoiding deformation of the pattern. By heating and pressing each pattern separately, the deformation caused by thermal expansion and contraction is offset.

[0019] This solution separates each pattern by a pressing plate, and cooperates with the heating strip to achieve the effect of heating each pattern separately. And by setting the conductive column and the power rail, only the heating strips under the pattern will be powered on and heated, while the remaining heating strips will not work (that is, the heating strips facing the blank section will not work), avoiding energy waste.

[0020] In this solution, by setting up a lifting frame, when the spacing of the pressing units is adjusted by the diamond-shaped telescopic frame, the width of the pushing frame in the left and right directions can also be adjusted synchronously to automatically adapt to the size of the pattern.

[0021] This solution sets a swing rod and a stop rod, so that when the pressing plate moves downward, the swing rod drives the heating strip below the pattern to move upward synchronously through the push frame, and no additional power source is required to drive the heating strip to move, saving costs. At the same time, the pressing plate and the heating strip are close to the transfer paper at the same time, so that the transfer paper moves with a small amplitude, avoiding deformation of the pattern due to the up and down vibration of the transfer paper.

[0034] The heating bar 5 works to heat the pattern 101 .

[0035] It also includes a base 1, a feeding mechanism 4 arranged on the base 1 to drive the transfer paper 10 to move left and right, a heating platform 50 arranged below the transfer paper 10, and a lifting mechanism 2 for pressing the transfer paper 10 against the heating platform 50; the lifting mechanism 2 includes a lifting plate 21 that slides longitudinally above the base 1, and a diamond-shaped telescopic frame 23 that telescopes in the left and right directions; the diamond-shaped telescopic frame 23 is evenly equipped with pressing units 3 in the left and right directions; when the diamond-shaped telescopic frame 23 drives the pressing units 3 to move, the spacing between the pressing units 3 is always equal; through the extension and contraction of the diamond-shaped telescopic frame 23, the pressing units 3 are directly opposite to the blank section 102.

[0036] The heating platform 50 includes a plurality of heating bars 5 closely arranged in the left-right direction; each heating bar 5 slides longitudinally on the base 1; the heating bars 5 penetrate the transfer paper 10 in the front-to-back direction; when the pressing unit 3 presses against the blank section 102, only the heating bar 5 located below the pattern 101 moves upward until it presses against the transfer paper 101 (such as Figure 7 as shown).

[0037] The left and right ends of two adjacent heating strips 5 are in contact with each other, and the upper end surface of the heating strip 5 is made of a metal material with good thermal conductivity; a heating wire is arranged inside the heating strip 5 .

[0038] The pressing unit 3 includes a pressing plate 31 connected to the diamond-shaped telescopic frame 23 and a lifting frame 32 longitudinally sliding on the pressing plate 31; a pushing frame 6 located below the heating platform 50 is arranged between the lifting frames 32 in two adjacent pressing units 3; the pushing frame 6 includes two pushing plates 61 connected for relative rotation; one pushing plate 61 is rotatably connected to one lifting frame 32; when the left-right length of the pushing frame 6 changes, the pushing frame 6 faces different numbers of heating strips 5.

[0039] The pressure plate 31 is provided with lifting frames 32 on both sides thereof; furthermore, there are push frames 6 below both sides thereof; when the push frames 6 drive the heating strip 5 to move upward, the push frames 6 on both sides thereof balance the force on the heating strip 5.

[0040] When each pressing plate 31 is located above the corresponding blank section 102 , the lifting frame 32 drives the pushing frame 6 to move, changing the length of the pushing frame 6 in the left and right directions, so that the pushing frame 6 is only opposite to the heating strip 5 directly below the pattern 101 .

[0041] The pressure plate 31 is provided with a sliding rod 311 which is slidably connected to the lifting frame 32; the pressing unit 3 also includes a rocker rod 33 which is rotatably connected to the sliding rod 311 and is located below the lifting frame 32; the rotating shaft of the rocker rod 33 is arranged in the horizontal direction; the side of the rocker rod 33 away from the rotating shaft of the rocker rod 33 abuts against the lower end of the lifting frame 32; a supporting rod 7 which is in contact with the rocker rod 33 is provided on the base 1 below the rocker rod 33; when the pressure plate 31 moves downward, the rocker rod 33 pushes the lifting frame 32 to move upward.

[0042] The rotation axes of the push rod 7 and the rocker arm 33 are not located in the same vertical plane, and the push rod 7 is located above the rotation axis of the rocker arm 33; when the pressure plate 31 moves downward, the rocker arm 33 rotates under the action of the push rod 7, and the angle between the rocker arm 33 and the vertical plane decreases, and then the rocker arm 33 pushes the lifting frame 32 to move upward.

[0043] Each of the heating strips 5 is provided with a conductive column 51; a power rail 8 is fixedly connected inside the base 1; when the push frame 6 drives the heating strips 5 to move upward until they abut against the transfer paper 10, the conductive column 51 is connected to the power rail 8, and the remaining heating strips 5 are not powered.

[0044] The conductive column 51 is connected to the heating wire.

[0045] The diamond-shaped telescopic frame 23 includes a plurality of connecting plate groups that are rotatably connected together in sequence; the connecting plate group includes two connecting plates 232 that are rotatably connected together; a center hole 231 is provided in the middle of the connecting plate 232; the two connecting plates 232 in the connecting plate group are rotatably connected together through the center hole 231; side holes 233 are respectively provided on both sides of the connecting plate 232; the side holes 233 between two adjacent connecting plate groups are rotatably connected; a connecting column 312 is provided at the upper end of the pressing plate 31; the connecting column 312 is rotatably connected to the center hole 231.

[0046] The lifting plate 21 is provided with a slide groove 212 distributed along the left and right directions; the upper end of the pressing plate 31 is provided with a slide column 313 slidably connected to the slide groove 212; the slide column 313 and the connecting column 312 enable the pressing plate 31 to slide only along the left and right directions without rotating.

[0047] The lifting plate 21 is rotatably connected with an adjusting screw 22 arranged along the left-right direction of the rotating shaft; the outer wall of the adjusting screw 22 is provided with two sections of thread grooves with opposite rotation directions; the two center holes 231 on both sides of the diamond-shaped telescopic frame 23 along the left-right direction are respectively rotatably connected with connecting sleeves 25 coaxially; one connecting sleeve 25 is transmission-connected to one thread groove; the lifting plate 21 is fixedly connected with an adjusting motor 24 for driving the adjusting screw 22 to rotate.

[0048] When the adjusting screw 22 rotates, the two connecting sleeves 25 move in opposite directions, thereby controlling the diamond-shaped telescopic frame 23 to telescope or extend, thereby changing the distance between the two center holes 231 .

[0049] The base 1 is rotatably connected to a plurality of lifting screws 11 longitudinally arranged with rotating shafts; the lifting plate 21 is provided with a threaded sleeve 211 transmission-connected to the lifting screws 11; each lifting screw 11 is connected to each other through a synchronous belt transmission; the base 1 is fixedly connected to a lifting motor 12 for driving a lifting screw 11 to rotate.

[0050] The feeding mechanism 4 includes two tangential feeding wheels 42 and a feeding motor 41 for driving the feeding wheels 42 to rotate; the transfer paper 10 is located between the two feeding wheels 42 .

[0051] In the initial state, the lifting plate 21 drives each pressing plate 31 to be located above the transfer paper 10, and the pressing plate 31 does not contact the transfer paper 10. Each heating strip 5 is located below the transfer paper 10 and does not contact the transfer paper 10. At this time, each heating strip 5 is located in the same plane.

[0052] Before use, first adjust the diamond telescopic frame 23 according to the width of the pattern 101 in the left and right directions; the adjusting motor 24 drives the adjusting screw 22 to rotate, and the adjusting screw 22 drives the two connecting sleeves 25 to move, so that the diamond telescopic frame 23 is extended and retracted, and finally the distance between the two adjacent pressing plates 31 is equal to the distance between the two adjacent patterns 101. At the same time, the sliding rod 311 drives the lifting frame 32 to move synchronously, and the pushing plate 61 rotates, so that the width of the pushing frame 6 in the left and right directions is slightly larger than the width of the pattern 101.

[0053] Then each feed wheel 42 rotates, driving the transfer paper 10 forward, and the transfer paper 10 with the pattern 101 moves to the bottom of the lifting plate 21, and the pressing plate 31 is directly opposite to the blank section 102. At this time, each heating strip 5 above the push frame 6 is located directly below the pattern 101.

[0054] Then the lifting motor 12 works, driving each lifting screw 11 to rotate, so that the lifting plate 21 moves downward. The lifting plate 21 drives the diamond-shaped telescopic frame 23 and each pressing plate 31 to move downward, and the lower end of the pressing plate 31 gradually approaches the transfer paper 10. At the same time, the swing rod 33 rotates under the action of the stop rod 7, so that the swing rod 33 pushes the lifting frame 32 to move upward.

[0055] As the lifting frame 32 moves upward, the pushing frame 6 drives each heating strip 5 facing the pushing frame 6 to move upward synchronously, and the heating strip 5 gradually approaches the transfer paper 10 .

[0056] Finally, the push frame 6 drives the heating strip 5 to abut against the lower end of the transfer paper 10, and the pressure plate 31 abuts against the upper end of the transfer paper 10, and pushes the transfer paper 10 to generate downward pressure, so that the transfer paper 10 is tightly against the heating strip 5. At the same time, the conductive column 51 on the heating strip 5 corresponding to the push frame 6 is electrically connected to the power rail 8.

[0057] Then the power rail 8 transmits current to the heating strip 5, and the heating strip 5 starts to heat. Each heating strip 5 heats the pattern 101. After the pattern 101 is heated, part of the liquid inside begins to evaporate, and finally the solid dye solidifies on the upper end of the transfer paper 10.

[0058] After a certain period of time, the pattern 101 is heated. The heating strips 5 stop heating, the lifting motor 12 controls each lifting screw 11 to rotate in the opposite direction, the lifting plate 21 rises, the pressing plate 31 separates from the transfer paper 10, and the swing rod 33 rotates, and then the lifting frame 32 drives the push plate 61 to move downward, and each heating strip 5 is reset downward.

[0059] Then the feeding wheel 42 starts working to drive the next section of transfer paper 10 to move to the lower end of the lifting plate 21 so as to continue heating the next section of the pattern 101 .
