Description

Technical Field

[0001] The present invention belongs to the technical field of ink printing and processing, and particularly relates to a high light-transmitting heater and its application. Background Art

[0002] Thermal transfer is a new printing process. The printing method of this process is divided into two major parts: transfer film printing and transfer processing. Transfer film printing uses dot printing (resolution up to 300 dpi) to pre-print patterns on the surface of the film. The printed patterns have rich levels, bright colors, are ever-changing, have small color differences, good reproducibility, can achieve the required effects of the designers of the patterns, and are suitable for mass production. Transfer processing transfers the delicate patterns on the transfer film to the surface of the product through one-time processing (heating and pressing) by a thermal transfer machine. After forming, the ink layer is integrated with the surface of the product, looking vivid and beautiful, greatly improving the grade of the product. Usually, the existing thermal transfer process first performs transfer film printing and then one-time transfer heating and pressing to directly form a finished product with a thermal transfer pattern. Since some of the inks in the pattern do not fully fuse with the product during the one-time heating and pressing process of the thermal transfer pattern ink layer, the pattern is not clear, resulting in defective products and production waste. Especially for some products that need to transfer certain specific patterns, such as fabrics, the clarity of the pattern directly affects the grade and selling price of the product.

[0039] The following combines the drawings to specifically clarify the implementation manner of the present invention. The drawings are only for reference and illustration, and do not constitute a limitation on the protection scope of the present invention patent. Embodiment 1

[0040] As Figures 1 to 7 shown, it is the first embodiment of the present invention, a high-transparency heater, which includes a backplate 2, a reflector 4, a translucent plate 5, a panel 1, a circuit board 7, a lamp board 8, a USB connector 10 and a plurality of LED lamps 9. The panel 1 covers the backplate 2 to form a cavity (not marked in the figure). The reflector 4 and the translucent plate 5 are stacked and received in the cavity. The reflector 4 is located between the translucent plate 5 and the backplate 2. A plurality of LED lamps 9 are provided on the side wall of the cavity. The light emitted by the plurality of LED lamps 9 enters the translucent plate 5 from the side of the translucent plate 5, is reflected by the reflector 4, passes through the translucent plate 5, and is emitted from the panel 1, thereby heating the pattern thermally transferred on the fabric, further consolidating the thermally transferred pattern, and increasing the clarity of the thermally transferred pattern.

[0041] As Figure 2 , Figure 3 and Figure 4As shown, the back plate 2 is preferably made of any one of ABS, PP, and PVC. In this embodiment, ABS plastic material is preferably used. A connection hole is provided at the center of the bottom of the back plate 2 for connecting the driving device. Two strip-shaped foot pads 3 are also provided at the bottom of the back plate 2, which have a buffering effect to prevent the back plate 2 from being damaged. A plurality of strip-shaped inner support portions 21 are convexly provided at the bottom of the cavity on the front surface of the back plate 2. The plurality of inner support portions 21 are arranged in a cross pattern to support the reflector 4 and dissipate heat from the reflector 4. A plurality of cross-arranged outer support portions 22 are convexly provided around the cavity of the back plate 2. The plurality of outer support portions 22 are used to support the panel 1 and the circuit board. The circuit board 7 and the USB connector 10 are both close to the plurality of LED lights 9, and the circuit board 7 is located between the outer support portion 22 and the panel 1.

[0042] As Figure 3 , Figure 5 , Figure 6 and Figure 7 shown, the reflector 4 is made of any one of PET, PP, PVC, SKC, and TORAY. In this embodiment, PET material is preferably used. The reflector 4 abuts against the plurality of inner support portions 21. A bent portion 41 extends upward and is bent at the end of the reflector 4 away from the LED lights 9. The height of the bent portion 41 is greater than or equal to the height of the light-transmitting plate 5.

[0043] As Figure 3 , Figure 5 and Figure 6 shown, the thickness range of the light-transmitting plate 5 is 1.0 mm to 2.5 mm. The light-transmitting plate 5 is an FRP fiberglass plate or a sunlight PC board. Since the FRP fiberglass plate is mainly composed of a high-performance upper film, reinforced polyester, and glass fibers, the upper film should play a good role in anti-ultraviolet and anti-static. Among them, anti-ultraviolet is to protect the polyester of the FRP fiberglass plate from yellowing and aging and losing the light-transmitting characteristics prematurely, while anti-static is to ensure that the dust on the surface is easily washed away by rain or blown away by wind, maintaining a clean and beautiful surface. Therefore, the FRP fiberglass plate has good anti-breakage, easy cleaning, acid and alkali resistance, etc. Its daylighting light is in a scattered state, the light is soft, and the light transmittance retention rate is high. Therefore, in the present invention, the light-transmitting plate 5 is preferably an FRP fiberglass plate. The light-transmitting plate 5 is received in the reflector 4 to prevent the light emitted by the LED lights 9 from directly emitting from the side of the light-transmitting plate 5, wasting energy.

[0044] As Figure 4 , Figure 5 and Figure 6As shown, multiple LED lights 9 are arranged at intervals in a row on a strip-shaped light board 8 on the side wall of the cavity of the back plate 2. The multiple LED lights 9 are located above the reflector 4 and face the side of the light-transmitting plate 5. The distance between the multiple LED lights 9 and the light-transmitting plate 5 is greater than zero, so that the multiple LED lights 9 can smoothly enter the light-transmitting plate 5 from the side of the facing light-transmitting plate 5. On the one hand, the circuit board 7 is electrically connected to the multiple LED lights 9 through the light board 8. On the other hand, the circuit board 7 is electrically connected to the USB connector 10. Since the circuit board 7 is the main control circuit board, the circuit board 7 can control the power-on of the multiple LED lights 9 with an external power supply. At the same time, it directly controls the heating state and heating temperature of the multiple LED lights 9.

[0045] As Figure 1 and Figure 3 shown, since acrylic is a plastic polymer material with good transparency, chemical stability, weather resistance, easy dyeing, easy processing, and beautiful appearance, the panel 1 of the present invention is preferably an acrylic panel. A plurality of buttons are provided on the working surface of the panel 1, such as a temperature increase button, a temperature decrease button, and a switch. Each button is electrically connected to the circuit board 7 so that the circuit board 7 can control the heating state and heating temperature of the heater. The panel 1 and the back plate 2 are connected by double-sided adhesive tape 6 or screwed. In order to make the panel 1 contact the product flatly and not affect the uniformity of heating, the present invention preferably adheres the panel 1 and the back plate 2 together through the double-sided adhesive tape 6. The double-sided adhesive tape 6 is in a frame shape, so that the periphery of the panel 1 is tightly adhered to the outer support portion 22.

[0046] Referring to Figures 1 to 7 , the working principle of the heater in this embodiment is as follows: The circuit board 7 controls the multiple LED lights 9 to emit light. The light emitted by the multiple LED lights 9 enters the light-transmitting plate 5 from the side of the light-transmitting plate 5. Part of the light in the light-transmitting plate 5 is directed to the bottom of the reflector 4, and the other part of the light directly hits the bent portion of the reflector 4. The reflector 4 reflects all the light back to the light-transmitting plate 5. The light is refracted by the light-transmitting plate 5 and exits from the working surface of the panel 1, irradiating on the pattern that has been heat transfer printed, heating and consolidating the pattern that has been heat transfer printed, and making the unclear pattern clear. Embodiment 2

[0047] As Figure 8 and Figure 9 shown are the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: in this embodiment, a plurality of light inlet grooves 51 are provided on the side of the light-transmitting plate 5. The plurality of light inlet grooves 51 correspond to the plurality of LED lights 9 one by one. The LED lights 9 partially extend into the corresponding light inlet grooves 51, so that the light emitted by the LED lights 9 enters the light-transmitting plate 5 more concentratedly, making full use of the energy of the LED lights 9. When the multiple LED lights 9 emit light, the light enters the light-transmitting plate 5 from the light inlet grooves 51 on the side of the light-transmitting plate 5. Other structures and working principles are the same as those of the first embodiment and will not be elaborated here.

[0048] After the heater of the present invention is used for transfer printing to form a pattern, it has high light transmittance and is used for further heating and consolidation treatment of the product with the printed pattern. The usage method is as follows:

[0049] (1). The panel 1 of the heater faces downward, and the driving device is installed above the heater. The driving device drives the whole heater to move downward until the panel 1 of the heater is in flat contact with the pattern that has been heat transfer printed below the heater, and the heater starts to heat and consolidate the heat transfer printed pattern.

[0050] (2). The panel 1 of the heater faces upward, and the driving device is installed below the heater. The driving device drives the whole heater to move upward, and the heat transfer printed fabric is placed flat on the panel 1 so that the panel 1 is in flat contact with the heat transfer printed pattern, and the heater starts to heat and consolidate the heat transfer printed pattern.

[0051] Since the heater of the present invention uses an FRP fiberglass board for light transmission, it can effectively block most ultraviolet rays, making the heater have the characteristics of strong ultraviolet resistance, strong chemical corrosion resistance, strong self-cleaning ability, strong anti-aging ability, strong anti-powdering ability and high light transmittance retention. Furthermore, it improves the clarity of the heat transfer printed pattern and the product quality. The heater of the present invention has the optical property of generating double beams, and it has a basic spectral transmittance function for fabrics. The heating temperature range of this heater is 60°C to 125°C, and the transmittance range is 0.0 to 100%.

[0052] The above-disclosed are only the preferred embodiments of the present invention, and the scope of the patent protection of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
