Description

Technical Field

[0001] The invention relates to the technical field of transfer machines, in particular to a digital transfer machine. Background Art

[0002] Digital transfer machine is an advanced printing equipment, which plays an important role in the modern printing industry. Digital transfer machine prints digital images or patterns directly on special transfer paper, and then uses thermal transfer, water transfer and other technologies to transfer the patterns on the transfer paper to various material surfaces, such as textiles, ceramics, metals, plastics, etc. In the thermal transfer process, the digital transfer machine first prints the image on the thermal transfer paper, and then transfers the pattern on the thermal transfer paper to the target material through heating and pressure.

[0003] Before transferring the pattern on the transfer paper to the textile, the current digital transfer machine needs to load the transfer paper feeding roller with the transfer paper. After the transfer paper on the transfer paper feeding roller is used up, the machine needs to be stopped for manual replacement. This operation has the following disadvantages:

[0004] 1. Long downtime: Each replacement of the transfer paper roller requires downtime. In large-scale production, frequent downtime for replacement will lead to longer overall production time. For example, for an efficiently operated clothing printing workshop, hundreds of printed garments may be produced per hour. Each downtime to replace the transfer paper roller may take several minutes. The accumulation of these few minutes will lead to a significant drop in production.

[0005] 2. Impact of temperature and pressure changes: After stopping to replace the transfer paper roller, the digital transfer machine needs to be restarted and preheated. During this process, parameters such as temperature and pressure of thermal transfer may not be restored to the optimal state immediately. For example, unstable temperature during thermal transfer may cause the pattern transfer to be unstable and the color to be uneven, affecting the transfer quality of textiles.

[0006] In order to solve the above-mentioned drawbacks, we hereby propose a digital transfer machine. Summary of the invention

[0007] In order to solve the above technical problems, the embodiment of the present application provides a digital transfer machine, including a transfer machine body and an extension frame, wherein a heat transfer roller is installed in the transfer machine body, and a transfer paper winding roller is installed on the extension frame, and further includes:

[0008] The C-shaped frame is fixed on the extension frame, and the C-shaped frame has two mounting positions, each of which is equipped with a transfer paper feeding roller;

[0009] An automatic feeding assembly is arranged on the extension frame, and the automatic feeding assembly is used to make the end of the transfer paper on another transfer paper feeding roller stick to the transfer paper on one transfer paper feeding roller before the transfer paper on the other transfer paper feeding roller is about to be used up, so as to realize automatic alternating feeding of the transfer paper feeding rollers at the two installation positions;

[0010] Two sets of auxiliary guide rollers, both of which are installed in the transfer machine body, and the two sets of auxiliary guide rollers are respectively located at the front and rear sides of the thermal transfer operation of the thermal transfer roller, and a capacitive thickness sensor is installed on one side between the two auxiliary guide rollers;

[0011] The adjustment component is used to adjust the movement of the thermal transfer roller after the capacitive thickness sensor detects a thickness change.

[0012] In some embodiments, brackets distributed vertically are fixed on the C-shaped frame, brackets are provided on the brackets, and pressure sensors are embedded in the bottom of the brackets.

[0013] In some embodiments, the automatic loading assembly includes an L-shaped mounting plate fixed to the side of the transfer body, and two protrusions distributed upper and lower are integrally formed on the surface of the mounting plate facing the transfer paper loading roller, a first motor is installed inside the protrusion, a swing plate is installed at the output end of the first motor, a first electric telescopic rod is installed through the end of the swing plate, and a suction cup is installed at the output end of the first electric telescopic rod.

[0014] In some embodiments, a through groove is provided on the mounting plate and between the two protrusions, a glue delivery tube is provided inside the through groove, a nozzle is installed at the glue outlet end of the glue delivery tube, a second electric telescopic rod is also installed in the through groove, and the output end of the second electric telescopic rod is connected to the glue delivery tube through a connecting plate.

[0015] In some embodiments, at least a portion of the glue delivery tube is a hard tube, and a section of the glue delivery tube connected to the second electric telescopic rod is a hard tube.

[0016] In some embodiments, the adjustment assembly includes a third motor installed on the inner wall of the transfer body and a rack installed on the end of the thermal transfer roller. A gear is installed on the output end of the third motor, and the gear is meshed and connected to the rack.

[0017] In some embodiments, a cutting assembly is also installed on the extension frame, and the cutting assembly is located near the transfer paper winding roller, and the cutting assembly is used to cut the transfer paper after the transfer paper winding roller winds up a sufficient amount of transfer paper to complete the thermal transfer.

[0018] In some embodiments, the cutting assembly includes two vertical plates symmetrically fixed on an extension frame, wherein a second motor is installed on the upper end of the outer wall of one of the vertical plates, a screw is connected to the output end of the second motor, a screw nut seat is installed on the outside of the screw, a convex plate is fixed on the top of the screw nut seat, a third telescopic rod is installed through the end of the convex plate, and a cutting knife is installed on the bottom end of the third telescopic rod.

[0019] In some embodiments, a plurality of guide rollers are provided inside the transfer body and along the transfer direction, and protective covers are provided around the peripheries of the plurality of guide rollers.

[0020] In some embodiments, a guide rod is fixed to a side of the rack facing away from the thermal transfer roller, and a guide groove adapted to the guide rod is formed on the inner side wall of the transfer body.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. Improve production efficiency: When the pressure sensor detects that the transfer paper is about to run out, the automatic feeding component starts immediately, so that the new transfer paper is attached to the previous transfer paper that is about to run out, achieving seamless connection, which avoids production interruptions caused by running out of transfer paper and greatly improves production efficiency; and the pressure sensor can transmit the signal to the controller in time, and the controller quickly controls the operation of the automatic feeding component. The whole process responds quickly and reduces waiting time.

[0023] 2. Reduce labor costs: The design of automatic and continuous feeding reduces the dependence on manual operation. Operators do not need to pay attention to the use of transfer paper all the time. They only need to operate when a new roll of transfer paper needs to be replaced, which reduces labor costs.

[0024] 3. Ensure transfer quality: The automatic feeding component can ensure a stable supply of transfer paper, avoiding transfer quality problems caused by untimely or uneven supply of transfer paper; the new transfer paper can be accurately attached to the previous transfer paper that is about to be used up, ensuring the continuity and consistency of the transfer process and improving the transfer quality.

[0025] 4. Improve the transfer quality: A capacitive thickness sensor is set to monitor the thickness of the transfer paper at the adhesion point, and an adjustment component is provided. This allows the thermal transfer roller to be quickly and accurately moved back and the thermal transfer process to be paused when the thermal transfer state needs to be released. When the thermal transfer needs to be continued, the thermal transfer state can be flexibly controlled so that the part of the transfer part that is not overlapped by the transfer paper is not transferred. This can effectively avoid blurring, ghosting and other problems caused by overlapping transfers, improve the clarity and quality of the transfer, ensure that each transfer area can be accurately transferred, and reduce the scrap rate.

[0026] 5. Save resources: Not transferring the overlapping parts can avoid wasting transfer materials and energy. The thermal transfer process usually consumes a certain amount of heat and transfer materials. By avoiding the transfer of overlapping parts, resources can be saved and production costs can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0044] Example 1: Please refer to Figure 1-Figure 9As shown, the present invention provides a technical solution: a digital transfer machine, including a transfer machine body 1 and an extension frame 2, a heat transfer roller 12 is installed in the transfer machine body 1, a transfer paper winding roller 9 and a cloth roller are installed on the extension frame 2, wherein the cloth roller includes a cloth feeding roller and a cloth winding roller, a controller can be embedded on the transfer machine body 1, a plurality of guide rollers 7 are arranged inside the transfer machine body 1 and along the transfer direction, these guide rollers 7 play the role of guiding and supporting the transfer material, ensuring the smooth progress of the transfer process, and a protective cover 8 is arranged on the periphery of the plurality of guide rollers 7. During the operation of the transfer machine, the guide rollers 7 will rotate, and the protective cover 8 is located on the periphery, which can effectively prevent the operator from rotating during the operation. The transfer paper feeding roller 4 is installed on the C-shaped frame 3, and the transfer paper feeding roller 4 is installed on each mounting position. Secondly, the C-shaped frame 3 is fixed with a bracket 31 distributed up and down, and a bracket 32 ​​is provided on the bracket 31. A pressure sensor 33 is embedded in the bottom of the bracket 32. The pressure sensor 33 can monitor the weight of the transfer paper feeding roller 4 with the transfer paper rolled on it in real time. As the transfer work is carried out, the weight of the transfer paper feeding roller 4 is increased. The transfer paper gradually decreases, and the weight will also decrease accordingly. The pressure sensor 33 can monitor this change in real time. When the weight drops to a certain level, a signal can be sent to the controller, so that the controller can control the automatic feeding component 5 to start in time and replenish the transfer paper in time to avoid production interruption due to insufficient transfer paper. The controller quickly controls the automatic feeding component 5 to operate, and the whole process responds quickly, reducing the waiting time. The automatic feeding component 5 is arranged on the extension frame 2, and the automatic feeding component 5 is used to make the end of the transfer paper on the other transfer paper feeding roller 4 attached to it before the transfer paper on one transfer paper feeding roller 4 is about to be used up, so as to achieve two The transfer paper feeding roller 4 at the installation position automatically feeds alternately; two groups of auxiliary guide rollers 10 are installed in the transfer machine body 1, and the two groups of auxiliary guide rollers 10 are respectively located at the front and rear sides of the thermal transfer operation of the thermal transfer roller 12, each group of auxiliary guide rollers 10 includes two parallel auxiliary guide rollers 10, and a capacitive thickness sensor 11 is installed on one side between the two auxiliary guide rollers 10; the adjustment component 13 is used to adjust the movement of the thermal transfer roller 12 after the capacitive thickness sensor 11 detects the thickness change. When the capacitive thickness sensor 11 detects the thickness change, the adjustment component 13 can adjust the movement of the thermal transfer roller 12 in time to stop the transfer of the overlapping area of ​​the transfer paper.

[0045] Among them, see Figure 4 and Figure 5As shown, the automatic feeding assembly 5 includes an L-shaped mounting plate 51 fixed to the side of the transfer machine body 1. Two protrusions 511 distributed up and down are integrally formed on the side of the mounting plate 51 facing the transfer paper feeding roller 4. A first motor 52 is installed inside the protrusion 511. The protrusion 511 provides a mounting position for the first motor 52. The design of the protrusion 511 increases the stability of the installation and ensures that the first motor 52 can operate normally. A swing plate 53 is installed at the output end of the first motor 52. The first motor 52 is a deflection motor. The swing plate 53 can be accurately controlled in its rotation angle. A first electric telescopic rod 55 is installed through the end of the swing plate 53. A suction cup 56 is installed at the output end of the first electric telescopic rod 55. The suction cup 56 can absorb the transfer paper to realize automatic loading of the transfer paper. By starting the first motor 52 in the protrusion 511, the swing plate 53 can be rotated to move the first electric telescopic rod 55 to face the end of the transfer paper extending from the transfer paper loading roller 4, and the suction cup 56 is moved by the first electric telescopic rod 55 to absorb the end of the transfer paper.

[0046] See also Figure 4 and Figure 5 As shown, a through groove 54 is provided on the mounting plate 51 and between the two protrusions 511, a glue feeding tube 57 is provided inside the through groove 54, a nozzle 59 is provided at the glue outlet end of the glue feeding tube 57, and the nozzle 59 is used to spray the glue accurately at the required position of the transfer paper, and a second electric telescopic rod 58 is also provided in the through groove 54, and the output end of the second electric telescopic rod 58 is connected to the glue feeding tube 57 through a connecting plate, so that the second electric telescopic rod 58 can control the movement of the glue feeding tube 57, thereby adjusting the position of the nozzle 59, and the glue feeding tube 57 is used to transport glue liquid, and a glue pump can be installed at the feeding end of the glue feeding tube 57, and the glue liquid is extracted by the glue pump, and the transported glue liquid is sprayed onto the transfer paper to be adhered through the nozzle 59.

[0047] At least part of the glue delivery tube 57 is a hard tube, and the section of the glue delivery tube 57 connected to the second electric telescopic rod 58 is a hard tube. This design has the following advantages:

[0048] 1. Stability: The hard tube part can provide better stability, ensuring that the glue delivery tube 57 will not be excessively bent or deformed during movement, thereby ensuring stable delivery of glue.

[0049] 2. Precise control: The hard tube part is easier to achieve precise position control, so that the second electric telescopic rod 58 can more accurately adjust the position of the nozzle 59 and improve the accuracy of glue spraying.

[0050] See also Figure 7 and Figure 8As shown, the adjustment component 13 includes a third motor 131 installed on the inner wall of the transfer body 1 and a rack 133 installed on the end of the thermal transfer roller 12. The output end of the third motor 131 is installed with a gear 132, and the gear 132 is meshed and connected to the rack 133. After the capacitive thickness sensor 11 on the front side of the transfer detects the thickness of the transfer paper at the adhesion, the third motor 131 can be started in time through the controller, and the gear 132 can be driven to rotate by the output end of the third motor 131, thereby driving the gear 132 to move backward, so that the thermal transfer roller 12 originally attached to the transfer paper can be moved backward to release the thermal transfer state of the thermal transfer roller 12. The capacitive thickness sensor on the rear side of the transfer After 11 detects the thickness of the transfer paper at the adhesion point, the controller also starts the third motor 131 to reverse, so that the backward-moving thermal transfer roller 12 moves forward and returns to its original position to continue the thermal transfer. The overlapping part of the transfer paper is not transferred, and this part is not transferred, which can effectively avoid blurring, ghosting and other problems caused by overlapping transfer, improve the clarity and quality of the transfer, ensure that each transfer area can be accurately transferred, reduce the scrap rate, and not transfer the overlapping part to avoid wasting transfer materials and energy. The thermal transfer process usually consumes a certain amount of heat and transfer materials. By avoiding the transfer of overlapping parts, resources can be saved and production costs can be reduced.

[0051] See also Figure 1 As shown, a cutting assembly 6 is also installed on the extension frame 2. The cutting assembly 6 is located close to the transfer paper winding roller 9, and the cutting assembly 6 is used to cut the transfer paper after the transfer paper winding roller 9 winds up a sufficient amount of transfer paper to complete the thermal transfer.

[0052] See also Figure 6 As shown, the cutting assembly 6 includes two vertical plates 61 symmetrically fixed on the extension frame 2, wherein a second motor 62 is installed on the upper end of the outer wall of one of the vertical plates 61, and a lead screw 63 is connected to the output end of the second motor 62, and a lead screw nut seat 64 is installed on the outside of the lead screw 63, and a convex plate 65 is fixed to the top of the lead screw nut seat 64, and a third telescopic rod 66 is installed through the end of the convex plate 65, and a cutter 67 is installed at the bottom end of the third telescopic rod 66. After the transfer paper winding roller 9 has wound up a certain amount of transfer paper, the second motor 62 can be started, and the second motor 62 can be used to drive the lead screw 63 to rotate, so as to realize the rotation of the lead screw nut seat 64, and then the cutter 67 is adjusted back and forth to realize the cutting of the transfer paper, wherein the lifting and lowering of the cutter 67 is realized by the third telescopic rod 66.

[0053] In summary, in specific use, two transfer paper loading rollers 4 with transfer paper can be initially set, and the end of the transfer paper on the transfer paper loading roller 4 is made to bulge outward, and then the transfer paper on one of the transfer paper loading rollers 4 is manually loaded. As the transfer progresses, the transfer paper on the transfer paper loading roller 4 becomes less and less. When the pressure sensor 33 detects that the transfer paper is about to run out, the signal can be transmitted to the controller, and the controller controls the automatic loading component 5 to operate, so that the transfer paper on the other transfer paper loading roller 4 is attached to the previous transfer paper that is about to run out, and is guided into the transfer machine body 1. The transfer paper loading roller 4 that has run out of transfer paper can be removed and replaced with a new transfer paper loading roller 4 provided with transfer paper. Such a cycle can realize automatic and continuous loading, avoid interruptions, and achieve seamless connection, which avoids production interruptions caused by running out of transfer paper, greatly improves production efficiency, and the automatic loading component 5 can ensure a stable supply of transfer paper, avoiding transfer quality problems caused by untimely or uneven supply of transfer paper. Secondly, the new transfer paper can be accurately attached to the previous transfer paper that is about to be used up, ensuring the continuity and consistency of the transfer process and improving the transfer quality.

[0054] In addition, it should be noted that the same two groups of alternately usable feeding rollers can be provided at the cloth feeding rollers, and an automatic feeding assembly 5 can be provided for feeding, so as to realize continuous feeding.

[0055] Example 2: Please refer to Figure 2 and Figure 8 As shown, this embodiment is an extension of the embodiment 1: specifically, a guide rod 134 is fixed to the side of the rack 133 away from the thermal transfer roller 12 , and a guide groove adapted to the guide rod 134 is provided on the inner wall of the transfer body 1 .

[0056] Through the above, when adjusting the position of the thermal transfer roller 12, the operator can achieve a slight position adjustment by controlling the movement of the rack 133. The sliding of the guide rod 134 in the guide groove can provide high-precision positioning, ensuring that the thermal transfer roller 12 can accurately move to the desired position, thereby ensuring the transfer quality. When the position of the thermal transfer roller 12 needs to be adjusted, the guide rod 134 slides along the guide groove to ensure that the movement is always carried out along the established path without deviation or shaking. Secondly, this design can effectively prevent the rack 133 from twisting or deforming during the movement. Since the rack 133 usually needs to transmit power or bear a certain force, it may be twisted due to uneven force without guidance, affecting its normal operation. The cooperation between the guide rod 134 and the guide groove can share part of the force and keep the shape of the rack 133 stable.

[0057] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
