[0003] In the field of clothing and textile decoration, heat transfer technology is a widely used method for transferring design patterns onto different materials. The current production process of clothing patch is to coat the fabric with release paper, then laser cut the material into the appropriate size, and finally laser engrave the pattern. With this process, the color of the patch is determined by the color of the fabric, and the pattern color is monotonous, which is not suitable for promotion and use.

[0004] The invention patent with patent publication number CN113619271A discloses a method and device for preparing multi-style heat transfer cloth patches. The technical means of this invention is to set the cloth patch base and the heat transfer film separately. The heat transfer film is easy to make and has a variety of colors. The pattern on the heat transfer film can be pressed onto the cloth patch base by pressing, thereby making the style of the entire heat transfer cloth patch more diverse.

[0005] However, the invention also has the following shortcomings during specific operation:

[0043] In a specific embodiment, as shown in the attached Figure 1 、 8 As shown, a moving structure is provided at the connection between the mobile platform 2 and the base plate 1, wherein the moving structure includes a screw rod 9, a mounting groove 10 is provided on the surface of the base plate 1, the screw rod 9 is installed inside the mounting groove 10, and a first motor 11 is provided at one end of the screw rod 9, a threaded block 12 is provided on the outside of the screw rod 9, the output end of the first motor 11 is coaxially connected to the screw rod 9 inside the mounting groove 10, the threaded block 12 is threadedly connected to the outside of the screw rod 9, and the threaded block 12 is fixedly installed at the bottom of the mobile platform 2.

[0044] Specifically, the mobile structure of the device can be used to enable the mobile platform 2 to drive the cloth patch base 3 to pass through the bracket 4 for data identification and enter the interior of the support frame 6 for pressing processing. Specifically, when the cloth patch base 3 is moved, the first motor 11 is used to drive the screw 9 inside the installation groove 10 to rotate, so that the threaded block 12 moves laterally inside the installation groove 10, and the threaded block 12 drives the mobile platform 2 to move laterally, thereby driving the cloth patch base 3 to move.

[0045] In a specific embodiment, as shown in the attached Figure 2 、 3 As shown in Figures 5 and 7, the connection between the cloth patch base 3 and the movable platform 2 and the connection between the heat transfer film 8 and the lower pressing plate 7 are both provided with clamping members, the clamping members include two L-shaped plates 13, the vertical cross-section shapes of the movable platform 2 and the lower pressing plate 7 are both set to be convex, the two L-shaped plates 13 are both symmetrically arranged at the top of the movable platform 2 and the bottom of the lower pressing plate 7, a pressing plate 14 is arranged inside the L-shaped plate 13, a first magnetic plate 15 is arranged at the bottom of the pressing plate 14, a second magnetic plate 16 that is magnetically attracted to the first magnetic plate 15 is provided on the surface of the movable platform 2 and the lower pressing plate 7 and at the bottom of the first magnetic plate 15, and a number of pressing springs 17 are connected between the pressing plate 14 and the L-shaped plate 13.

[0046] Specifically, in this structure, the heat stamping film 8 and the cloth patch base 3 that are pressed against each other can be installed on the movable platform 2 and the lower pressing plate 7 respectively. Specifically, the heat stamping film 8 and the cloth patch base 3 are placed on the movable platform 2 and the lower pressing plate 7, and it is ensured that the heat stamping film 8 and the cloth patch base 3 are not wrinkled, so that the heat stamping film 8 and the cloth patch base 3 respectively extend to the surface of the second magnetic plate 16 at the corresponding L-shaped plate 13. Under the action of the clamping spring 17, the lower pressing plate 7 drives the first magnetic plate 15 to press down, so that the two ends of the heat stamping film 8 and the cloth patch base 3 are respectively located between the first magnetic plate 15 and the second magnetic plate 16. The first magnetic plate 15 and the second magnetic plate 16 are magnetically attracted to each other, thereby achieving a clamping effect on the two ends of the heat stamping film 8 and the cloth patch base 3, and ensuring that the heat stamping film 8 and the cloth patch base 3 are respectively installed on the movable platform 2 and the lower pressing plate 7.

[0047] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the surface of the cloth patch base 3 is laser engraved with multiple pattern outlines 18, and identification strips 19 are detachably attached to the surface of the cloth patch base 3 on both sides of the pattern outline 18 through adhesive, and the lower surface of the heat transfer film 8 is provided with pictures 20 with the same number as the pattern outline 18, and the pictures 20 correspond to the pattern outline 18.

[0048] Specifically, in this structure, the pattern outline 18 on the cloth patch base 3 can be adapted to the picture 20 on the heat transfer film 8, so that the picture 20 is attached to the inside of the pattern outline 18. At the same time, it is convenient for the operator to peel off the film on the heat transfer film 8. The identification strip 19 can be attached to the cloth patch base 3 through an adhesive, which is convenient for the operator to tear it off later without affecting the aesthetics of the entire heat transfer.

[0049] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown in Figures 7 and 8, a plurality of positioning holes 21 are provided on the mobile platform 2, and the bottom of the lower pressing plate 7 is provided with positioning rods 22 with the same number as the positioning holes 21 and with a compatible structure.

[0050] Specifically, in this structure, after the lower pressing plate 7 and the movable platform 2 are fitted together, the positioning rod 22 can be extended to the inside of the positioning hole 21 to perform a positioning operation on the pressing of the lower pressing plate 7 and the movable platform 2 .

[0051] In a specific embodiment, as shown in the attached Figure 1 、 6 As shown, two electric push rods 23 are installed on the support frame 6, and the output ends of the two electric push rods 23 are connected to the lower pressing plate 7. A plurality of embedding holes are opened inside the lower pressing plate 7, and electric heating wires 24 are arranged inside the plurality of embedding holes.

[0052] Specifically, in this structure, the electric push rod 23 can drive the lower pressing plate 7 to move downward, and can press down the cloth base 3, while the electric heating wire 24 embedded in the embedding hole can generate high temperature to heat the pattern of the heat transfer film 8.

[0053] In a specific embodiment, as shown in the attached Figure 1 、 4 As shown, an execution structure is provided between the support frame 6 and the base plate 1, and the execution structure includes a screw 25. Rectangular grooves 26 are provided on the front and rear surfaces of the base plate 1. The screw 25 is installed inside one of the rectangular grooves 26, and a second motor 27 is provided at one end of the screw 25. A slide rod 28 is provided inside the other rectangular groove 26, a slider 29 is provided outside the slide rod 28, and an adjustment block 30 is provided outside the screw 25.

[0054] The output end of the second motor 27 is coaxially connected to the screw rod 9 inside one of the mounting grooves 10. The adjustment block 30 and the slider 29 are connected to the screw rod 25 and the slide rod 28 by threaded connection and sliding connection respectively. The adjustment block 30 and the slider 29 are fixedly mounted on the inner wall of the support frame 6 respectively.

[0055] Specifically, this structure can be used to match the heat transfer film 8 with the pattern outline 18 on the cloth patch base 3, ensuring that the heat transfer is attached to the inside of the pattern outline 18. Specifically, the second motor 27 drives the screw 25 inside one of the rectangular slots 26 to rotate, so that the adjustment block 30 moves, and the matching slider 29 slides outside the slide bar 28, which can make the support frame 6 move and adjust, so that the heat transfer position of the heat transfer film 8 corresponds to the position of the pattern outline 18 on the cloth patch base 3.

[0056] The present invention also provides a method for preparing various heat transfer fabric stickers, which is prepared using the above-mentioned device. The method comprises the following steps:

[0057] Step 1: Use a pressing roller to press the fabric and the release paper into one to obtain a composite fabric;

[0058] Step 2: Using a laser cutting machine to cut the obtained composite fabric into required sizes to obtain a fabric patch base 3;

[0059] Step 3: Use a laser to carve the outlines 18 of each pattern to be pressed onto each fabric patch substrate 3. The carving laser passes through the composite fabric of the fabric patch substrate 3 and partially extends to the release paper. The laser does not pass through the release paper. At the same time, identifiable identification strips 19 are attached to the surface of the fabric patch substrate 3 on both sides of the pattern outline 18 using an adhesive to obtain an identifiable fabric patch. The identification strips 19 can be torn off from the fabric patch substrate 3. At the same time, the identification strips 19 have data information on the position of the pattern outline 18, and the spacing between the identification strips 19 on both sides and the pattern outline 18 is the same. The data information can be captured and identified by the CCD camera 5, which has a light source for collecting the data information.

[0060] Step 4: Fix the identifiable cloth patch on the mobile platform 2 of the pressing device for transportation, and place the prepared heat transfer film 8 under the movable lower pressing plate 7 of the pressing device for fixing;

[0061] Step 5: Use the CCD camera 5 to first capture the identification strip 19 on the first fabric patch being conveyed and transmit the identified data to the control system of the pressing device for storage as execution data. Simultaneously, the lower pressing plate 7 presses downward to ensure that the heat transfer film 8 adheres to the contour of the fabric patch substrate 3. The pressing temperature of the lower pressing plate 7 is 110°C, and the pressing time is 5 seconds. Each pattern 20 on the heat transfer film 8 adheres to the fabric patch substrate 3.

[0062] Step 6: The mobile platform 2 continues to transport the unpressed fabric patch and uses the CCD camera 5 to capture the identification strip 19 on the unpressed fabric patch again. The control system of the pressing device adjusts the position of the lower pressing plate 7 based on the execution data of the last pressed fabric patch so that the heat transfer film 8 is aligned with the contour of the unpressed fabric patch substrate 3 for pressing. The unfinished fabric patch is heat-pressed in the same manner.

[0063] Step 7: tear off the film portion of the heat transfer film 8 and the identification strip 19 from the cloth patch after the heat transfer is completed, thereby completing the preparation of multiple heat transfer cloth patches.

[0064] Through the above steps, the cloth patch base 3 and the heat transfer film 8 are set separately. The style of the heat transfer film 8 is simple to make and the colors are diverse. The pattern on the heat transfer film 8 can be pressed onto the cloth patch base 3 by pressing, so that the style of the entire heat transfer cloth patch is more diverse and the cloth patch style is more colorful. In addition, the automatic recognition positioning method is adopted to ensure that the heat transfer on the heat transfer film 8 is completely attached to the pattern outline 18 of the cloth patch base 3, avoiding the heat transfer from the pattern outline 18 during pressing, reducing the burden of manual alignment, and being suitable for large-scale production of heat transfer cloth patches, improving the aesthetics of the product. The laser engraving method can facilitate the separation of the heat transfer part of the cloth patch from the cloth patch base 3 and facilitate peeling.

[0065] The following specifically describes the working principle of the present invention in preparing heat transfer cloth stickers or the specific use of the device:

[0066] 1. First, use a roller press to press the fabric and release paper together and cut them to obtain a fabric base 3. Place the fabric base 3 on the mobile platform 2, with both sides extending to the second magnetic plate 16 in the L-shaped frame. Tighten and fix both sides of the fabric base 3. Use the same method to install the prepared heat transfer film 8 on the position of the lower pressing plate 7.

[0067] 2. Start the device. First, the first motor 11 starts to drive the screw block 12 to move. The screw block 12 drives the mobile platform 2 to move horizontally, driving the first cloth patch substrate 3 to be pressed to the inside of the bracket 4. The CCD camera 5 inside the bracket 4 collects the identification strip 19 on the first cloth patch substrate 3 to be pressed. The identification strip 19 contains the specific layout position information of the pattern outline 18 on the cloth patch substrate 3. The information is transmitted to the control system of the device and stored. The specific layout position information of the pattern outline 18 on the identification strip 19 on the first cloth patch substrate 3 to be pressed is used as the execution data of the pressing position standard of other cloth patch substrates 3, including the pressing of the second cloth patch substrate 3 and the pressing of the third cloth patch substrate 3.

[0068] 3. After the specific layout position information of the pattern outline 18 on the identification strip 19 of the first cloth patch substrate 3 to be pressed on the cloth patch substrate 3 is identified and stored, the mobile platform 2 is driven to the support frame 6 to perform the pressing process on the first cloth patch substrate 3;

[0069] 4. When the second or subsequent fabric patch substrates 3 are to be ironed, the heat transfer film 8 and the fabric patch substrate 3 are installed in the above-described manner, and the position of the second identification strip 19 is collected and identified. When the mobile platform 2 drives the second fabric patch substrate 3 to move to the position of the support frame 6, the control system starts the second motor 27 according to the execution data (the ironing position of the pattern outline 18 of the first fabric patch substrate 3). The second motor 27 drives the support frame 6 to adjust its position, driving the ironing film to move above the second fabric patch substrate 3, and making the pattern of the ironing film correspond to the outline of the second fabric patch substrate 3;

[0070] 5. Start the electric push rod 23 to drive the lower pressing plate 7 to extend downward, pressing the hot stamping film onto the surface of the second fabric base 3. The electric heating wire 24 inside the lower pressing plate 7 quickly heats up to 110°C and continues hot stamping for 5 seconds. After hot stamping is completed, the lower pressing plate 7 and the movable platform 2 are separated. At this time, the pattern on the hot stamping film is attached to the inside of the pattern outline 18 on the fabric base 3. Finally, tear off the film on the hot stamping film and tear off the identification strip 19.

[0071] In summary, when pressing multiple fabric patch substrates 3, the present invention first identifies and stores the specific layout of the pattern outline 18 on the first fabric patch substrate 3 to be pressed, and then performs the pressing process on the first fabric patch substrate 3.

[0072] When the device performs pressing on the second cloth patch base 3 based on the pressing data of the first cloth patch base 3 and the distribution of the pattern outline 18, it will automatically fine-tune the corresponding position of the heat transfer on the pressing film and the pattern outline 18 on the second cloth patch base 3 and perform the pressing process.

[0073] It is worth noting that in the present invention, when performing heat stamping on the first cloth patch substrate 3, it is necessary to ensure that the pattern outline 18 on the first cloth patch substrate 3 corresponds to the pattern on the heat stamping film 8, and then when performing heat stamping on the second cloth patch substrate 3, the system can compare and locate the data information of the first substrate identification strip 19 with the data information of the second substrate identification strip 19.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
