Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer, in particular to a thermal transfer film feeding device for a thermal transfer machine. Background Art

[0002] A heat transfer machine is a device that transfers images or text onto various materials using heat transfer technology. This technology is widely used on surfaces such as clothing, hats, sports equipment, ceramics, metal, and wood. The heat transfer machine works by applying heat to transfer the image or text from heat transfer paper to the target material.

[0003] A thermal transfer machine is a printing device that primarily prints a special ink (called thermal transfer ink) onto specialized transfer paper. The thermal transfer machine then applies heat and pressure to the ink, transferring the pattern to the substrate, creating a durable image. During use, it is typically paired with a thermal transfer film feeder, which feeds the film underneath the machine for printing.

[0004] Therefore, when the thermal transfer film feeding device is in use, it is necessary to always maintain the flatness of the transfer film, thereby ensuring that the thermal transfer film device can print the pattern completely on the transfer film. When the traditional thermal transfer film device is in use, although it can ensure the straightening state of the transfer film to a certain extent, due to the rolling of the roller, the transfer film may be shifted and unevenly stressed, thereby causing wrinkles on the transfer film. Therefore, a thermal transfer film feeding device for a thermal transfer machine is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a heat transfer film feeding device for a heat transfer machine, which has the advantages of good flexibility and high stability, and solves the problem of insufficient flatness of the transfer film in the traditional heat transfer film feeding device.

[0006] In order to achieve the above-mentioned purpose of good flexibility and high stability, the utility model provides the following technical solution: a thermal transfer film feeding device for a thermal transfer machine, comprising a support frame, a conveying assembly arranged on the outside of the support frame, a driving assembly arranged on the top of the support frame, and a transfer film connected to the outside of the conveying assembly by transmission.

[0007] Furthermore, the conveying assembly includes several adjustment seats movably connected to the outside of the support frame, a lifting seat movably connected to the bottom of the adjustment seat, a limit block movably connected to the bottom of the adjustment seat, a pressing roller rotatably connected to the side of the lifting seat, a locking pin rotatably connected to the side of the lifting seat, several moving seats slidably connected to the outside of the support frame, a balancing roller rotatably connected to the side of the moving seat, and a positioning pin rotatably connected to the side of the moving seat.

[0008] Furthermore, a limit strip is provided at the bottom of the cross bar of the support frame, and a sliding slot is provided inside the adjustment seat for use with the cross bar of the support frame. The cross bar of the support frame passes through the sliding slot of the adjustment seat and is slidably connected to the adjustment seat.

[0009] Furthermore, a square sliding rod is provided at the bottom of the adjustment seat, a through-hole is provided at the top of the lifting seat, the sliding rod vertically passes through the through-hole of the lifting seat and is slidably connected to the lifting seat, and a threaded column is provided at the top of the limit block, which is screwed into the bottom of the sliding rod so that the limit block and the adjustment seat are fixedly installed by threads.

[0010] Furthermore, one end of the locking pin passes through the side wall of the lifting seat to the inside of the through hole of the lifting seat and is rotatably connected to the lifting seat through a thread. The surfaces of the pressing roller and the balancing roller are both provided with limiting grooves for limiting.

[0011] Furthermore, a through hole is opened on the side of the movable seat for use with the cross bar of the support frame. The cross bar of the support frame passes through the movable seat horizontally and is slidably connected to the movable seat. One end of the positioning pin passes through the side wall of the movable seat to the inside of the through hole and is connected to the movable seat by a threaded rotation.

[0012] Furthermore, the driving assembly includes a fixed plate fixedly installed on the top of the support frame, an inlet roller rotatably connected to the side of the fixed plate, a support plate fixedly installed on the top of the support frame, a driving roller rotatably connected to the side of the support plate, and a driving motor fixedly installed on the side of the support plate.

[0013] Furthermore, the output shaft of the driving motor passes through the supporting plate transversely and is fixedly mounted on the side of the driving roller, and limiting grooves are provided on the surfaces of the introduction roller and the driving roller.

[0014] Compared with the prior art, the present invention provides a heat transfer film feeding device for a heat transfer machine, which has the following beneficial effects:

[0015] 1. The thermal transfer machine uses a thermal transfer film feeding device. The transfer film is put on the outside of the guide roller, passed through the pressing roller, balance roller, balance roller and pressing roller in sequence, and then the head of the transfer film is pasted on the outside of the driving roller. After starting the driving motor, loosen the positioning pins and move the two balance rollers to the appropriate position to adapt to the transfer pattern. Then tighten the positioning pins to fix the movable base at the specified position of the support frame. Start the driving motor to drive the rotation of the driving roller, thereby realizing the conveying of the transfer film.

[0016] 2. The thermal transfer machine uses a thermal transfer film feeding device. By loosening the locking pin, the lifting seat and the pressing roller fall down under the influence of gravity to press the transfer film. The transfer film is stretched flat under the pulling force of the driving roller. At the same time, the lifting seat and the pressing roller press the transfer film on the upper surface of the transfer film, thereby ensuring that the transfer film remains flat at all times during the conveying process. The transfer film is limited in the grooves on the surfaces of the pressing roller and the balance roller and cannot shift, thereby ensuring that the transfer film is always flat during the entire conveying process, thereby solving the problem of insufficient flatness of the transfer film in the traditional thermal transfer film conveying device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 3 In this embodiment, a thermal transfer film feeding device for a thermal transfer machine includes a support frame 1, a conveying component 2 arranged on the outside of the support frame 1, a driving component 3 arranged on the top of the support frame 1, and a transfer film 4 connected to the outside of the conveying component 2 by transmission.

[0023] The conveying component 2 is configured to receive and convey the transfer film 4 while pressing the transfer film 4 to ensure the flatness of the transfer film 4 during the conveying process, and the driving component 3 rotates the rollers to realize the conveying of the transfer film 4.

[0024] In this embodiment, the conveying assembly 2 includes several adjustment seats 21 movably connected to the outside of the support frame 1, a lifting seat 22 movably connected to the bottom of the adjustment seat 21, a limit block 23 movably connected to the bottom of the adjustment seat 21, a pressing roller 24 rotatably connected to the side of the lifting seat 22, a locking pin 25 rotatably connected to the side of the lifting seat 22, several moving seats 26 slidably connected to the outside of the support frame 1, a balancing roller 27 rotatably connected to the side of the moving seat 26, and a positioning pin 28 rotatably connected to the side of the moving seat 26.

[0025] The adjusting seat 21 is provided to control the position of the lifting seat 22 , thereby controlling the distance between the pressing rollers 24 , thereby coordinating the distance between the moving seats 26 to adapt to the transfer of patterns of different sizes.

[0026] It should be noted that the number of pressing rollers 24 and balancing rollers 27 can be adjusted as needed.

[0027] In this embodiment, a limiting strip is provided at the bottom of the cross bar of the support frame 1, and a sliding groove is provided inside the adjustment seat 21 for use with the cross bar of the support frame 1. The cross bar of the support frame 1 passes through the sliding groove of the adjustment seat 21 and is slidably connected to the adjustment seat 21.

[0028] A limit strip is provided at the bottom of the support frame 1 to cooperate with a specially provided notch to limit the movement of the adjustment seat 21 to prevent the adjustment seat 21 from deviating during operation and causing displacement of the membrane.

[0029] It should be noted that the sliding between the adjustment seat 21 and the support frame 1 has a certain degree of damping, which can maintain the stability of the adjustment seat 21 when it is adjusted by external force.

[0030] In this embodiment, a square sliding rod is provided at the bottom of the adjusting seat 21, and a through-hole is provided at the top of the lifting seat 22. The sliding rod vertically passes through the through-hole of the lifting seat 22 and is slidably connected to the lifting seat 22. A threaded column is provided at the top of the limit block 23, and the threaded column is screwed into the bottom of the sliding rod so that the limit block 23 and the adjusting seat 21 are fixedly installed by threads.

[0031] A square slide bar is provided at the bottom of the adjustment seat 21 to pass through the lifting seat 22. At the same time, a limit block 23 is provided at the bottom of the slide bar to limit the bottom of the lifting seat 22. Although the lifting seat 22 can move up and down outside the slide bar at the bottom of the adjustment seat 21, the height difference of the lifting is limited.

[0032] In this embodiment, one end of the locking pin 25 passes through the side wall of the lifting seat 22 to the inside of the through hole of the lifting seat 22 and is connected to the lifting seat 22 by a threaded rotation. The surfaces of the pressing roller 24 and the balancing roller 27 are both provided with limiting grooves for limiting.

[0033] A locking pin 25 is provided on the side of the lifting seat 22 , which can not only lock the position of the lifting seat 22 but also allow the lifting seat 22 to slide up and down on the outside of the slide rod according to actual needs.

[0034] It should be noted that the limiting grooves on the surfaces of the pressing roller 24 and the balancing roller 27 have the same width and are located on the same line.

[0035] In this embodiment, a through hole is opened on the side of the movable seat 26 for use with the cross bar of the support frame 1. The cross bar of the support frame 1 passes through the movable seat 26 horizontally and is slidably connected to the movable seat 26. One end of the positioning pin 28 passes through the side wall of the movable seat 26 to the inside of the through hole and is connected to the movable seat 26 by a threaded rotation.

[0036] Positioning pins 28 are provided on the outside of the movable seat 26. When multiple movable seats 26 are provided for transfer, the position of the movable seat 26 can be adjusted according to the size of the actual transfer pattern, thereby controlling the length of the transfer film 4 between the movable seats 26 to adapt to the transfer pattern.

[0037] In this embodiment, the driving assembly 3 includes a fixed plate 31 fixedly installed on the top of the support frame 1, an introduction roller 32 rotatably connected to the side of the fixed plate 31, a support plate 33 fixedly installed on the top of the support frame 1, a driving roller 34 rotatably connected to the side of the support plate 33, and a driving motor 35 fixedly installed on the side of the support plate 33.

[0038] A fixed plate 31 is provided to cooperate with the introduction roller 32 to initially guide the transfer film 4 , and a driving motor 35 drives the driving roller 34 to rotate, thereby driving the transfer film 4 to be continuously transported inside the device.

[0039] In this embodiment, the output shaft of the driving motor 35 transversely passes through the supporting plate 33 and is fixedly mounted on the side of the driving roller 34 . Limiting grooves are provided on the surfaces of the introduction roller 32 and the driving roller 34 .

[0040] The working principle of the above embodiment is:

[0041] By putting the transfer film 4 on the outside of the introduction roller 32, passing it through the pressing roller 24, the balancing roller 27, the balancing roller 27 and the pressing roller 24 in sequence, and then sticking the head of the transfer film 4 to the outside of the driving roller 34, after starting the driving motor 35, loosening the positioning pin 28 and moving the two balancing rollers 27 to the appropriate position to adapt to the transfer pattern, then tightening the positioning pin 28 to fix the movable seat 26 at the specified position of the support frame 1, starting the driving motor 35 to drive the rotation of the driving roller 34, thereby realizing the transportation of the transfer film 4.

[0042] In addition, by loosening the locking pin 25, the lifting seat 22 and the pressing roller 24 fall down under the influence of gravity to press the transfer film 4. The transfer film 4 is stretched and flattened under the pulling force of the driving roller 34. At the same time, the lifting seat 22 and the pressing roller 24 press the transfer film 4 on the upper surface of the transfer film 4, thereby ensuring that the transfer film 4 remains flat at all times during the conveying process. The transfer film 4 is limited in the grooves on the surfaces of the pressing roller 24 and the balancing roller 27 and cannot shift, thereby ensuring that the transfer film 4 always remains flat during the entire conveying process, thereby solving the problem of insufficient flatness of the transfer film 4 in the traditional thermal transfer film conveying device.
