Description

Technical Field

[0001] The invention relates to the technical field of textile processing, and in particular to a heating device for processing polyester composite fabrics. Background Art

[0002] Polyester composite fabric refers to a fabric made by compounding polyester fiber with other materials (such as nylon, spandex, elastic fiber, polyester film, etc.) as the main component. It has the characteristics of lightness, softness, strong wear resistance, good washability and diverse functionality. It is widely used in clothing, shoes, luggage, household items and other fields, bringing convenience and comfort to people's lives.

[0003] Hot stamping is a common method for compounding polyester fabrics. It uses a heating roller and a pressure roller to combine the polyester coated with a molten adhesive layer with other fabrics. During the hot stamping process, the effective heating time of the fabric in contact with the heating roller is very short, so the heating roller needs to be heated to a higher temperature to melt the hot melt adhesive to meet the composite process. If the heating roller is heated to a temperature that is too low, it will not be enough to melt the hot melt adhesive to a suitable degree, but if the heating roller is heated to a temperature that is too high, it will easily cause fabric burns. It is difficult for current heating devices to accurately control the heating temperature of the heating roller. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1 , Figure 2 and Figure 3 As shown, the present invention is a heating device for processing polyester composite fabrics, comprising a heating box 1 and a composite fabric 2, wherein a feed port 101 and a discharge port 102 are respectively arranged at both ends of the heating box 1, and guide rollers 103 are rotatably installed in the feed port 101 and the discharge port 102, a group of fabric tensioning rollers 3 staggered in an upper and lower manner are rotatably installed in the heating box 1, and a group of hot stamping rollers 4 staggered in an upper and lower manner are rotatably installed between the fabric tensioning rollers 3, and the composite fabric 2 is transported from the feed port 101 to the discharge port 102 after passing through the corresponding fabric tensioning rollers 3 and the hot stamping rollers 4, wherein a pressing belt 5 is tensionedly arranged above one of the hot stamping rollers 4, and a pressing belt 5 is also tensionedly arranged below the other hot stamping roller 4, and the two groups of pressing belts 5 are respectively pressed against the upper surface and the lower surface of the composite fabric 2.

[0029] Specifically, by providing the fabric tensioning roller 3 and the pressing belt 5, during the heating process, the composite fabric 2 enters from the feed port 101, is tensioned by the fabric tensioning roller 3, and then passes around the upper and lower hot rolling rollers 4 in sequence, and the pressing belt 5 is used to press the large-area composite fabric 2 against the hot rolling roller 4, so that both sides of the composite fabric 2 can be sufficiently heated, so that both sides of the composite fabric 2 are heated evenly, and at the same time, the tension of the composite fabric 2 and the pressing belt 5 can be synchronously adjusted, which can not only keep the composite fabric 2 tensioned and smooth during the conveying process, but also make the pressing belt 5 tightened to better exert the pressing effect.

[0030] like Figure 4-Figure 7 As shown, a group of limit plates 6 are fixedly arranged between the hot rolling rollers 4, the two limit plates 6 are arranged opposite to each other with a gap, the composite fabric 2 passes through the gap between the inner walls of the limit plates 6, the outer walls of the two limit plates 6 are fixedly provided with support frames 7, a pair of detection slots 601 are penetrated on the limit plates 6, the two support frames 7 are centrally symmetrically arranged and correspond to the corresponding detection slots 601, and the support frames 7 are respectively provided with power connection components 8 and detection components 9.

[0031] The power connection component 8 includes a pair of power connection blocks 801, a rotating shaft 401 is coaxially arranged inside the hot ironing roller 4, a conductive ring 402 is fixedly arranged on the outside of the rotating shaft 401, the hot ironing roller 4 is fixedly arranged on the outside of the conductive ring 402, an annular receiving groove 403 is arranged inside the hot ironing roller 4, and the power connection block 801 is arranged in the annular receiving groove 403 and is in sliding contact with the conductive ring 402.

[0032] Specifically, the hot rolling roller 4 is rotatably installed in the heating box 1 via the rotating shaft 401. During the heating process, the conductive ring 402 and the hot rolling roller 4 rotate synchronously with the rotating shaft 401. At the same time, the electric contact block 801 always maintains sliding contact with the conductive ring 402 in the annular receiving groove 403, so that the conductive ring 402 can also maintain a power-on state during the rotation process, thereby realizing the electric heating process. In actual application, a through groove connected to the annular receiving groove 403 is provided in an annular manner on the surface of the hot rolling roller 4. The function of the through groove is to provide a movable space for the wire 802 connected to the electric contact block 801, so that when the hot rolling roller 4 rotates, the wire 802 will slide in the through groove without being entangled on the hot rolling roller 4.

[0033] The detection assembly 9 includes a sliding plate 901, and a rotating frame 902 is extended from one end of the sliding plate 901 close to the limit plate 6. A detection wheel 903 is rotatably installed in the rotating frame 902. The detection wheel 903 extends into the detection slot 601 and rests on the surface of the composite fabric 2. The detection wheel 903 drives the sliding plate 901 to move linearly to change the current size of the closed circuit in the power connection assembly 8, thereby adjusting the heating temperature of the hot ironing roller 4.

[0034] Specifically, by setting the limit plate 6, the power connection component 8 and the detection component 9, the composite fabric 2 passes through the gap between the limit plates 6 after being heated. When passing through the detection slot 601, the detection wheel 903 will abut against the surface of the composite fabric 2. Since the heating temperature directly affects the softening degree of the hot melt adhesive inside the composite fabric 2, the higher the melting degree of the hot melt adhesive, the softer the texture of the composite fabric 2, and the smaller the tension exerted on the detection wheel 903 against the surface of the composite fabric 2, and vice versa, the sliding distance of the sliding plate 901 driven by the detection wheel 903 against the surface of the composite fabric 2 is used to reflect the softening degree of the composite fabric 2. At the same time, the sliding process of the sliding plate 901 will also change the circuit size of the closed circuit in the power connection component 8, so that the heating temperature of the hot ironing roller 4 can be adaptively adjusted according to the softening degree of the composite fabric 2 after heating, so that the heating temperature is always maintained in an appropriate range to meet the melting temperature requirement of the hot melt adhesive in the composite fabric 2, so as to avoid the heating temperature being too high or too low.

[0035] like Figure 1 and Figure 3 As shown, the pressure belt 5 is sleeved on a pressure belt tensioning roller 501 and a pair of fixed rollers 502. The fixed rollers 502 are arranged on both sides of the corresponding hot ironing rollers 4. Slide blocks are arranged at both ends of the cloth tensioning roller 3 and the pressure belt tensioning roller 501. Slide grooves are longitudinally penetrated on both sides of the heating box 1. The cloth tensioning roller 3 and the pressure belt tensioning roller 501 are installed in the corresponding slide grooves by sliding up and down through the sliders.

[0036] Furthermore, tooth plates 104 are fixedly connected to the outer sides of the sliders, and the tooth plates 104 at both ends of the adjacent cloth tensioning rollers 3 and the pressure belt tensioning rollers 501 are arranged opposite to each other. Tensioning gear 105 and tensioning gear 2 106 are rotatably installed at both ends of the side walls of the heating box 1, and both ends of the tensioning gear 105 and the tensioning gear 2 106 are respectively meshed with the corresponding tooth plates 104, and a synchronous belt 107 is arranged between the gear shafts of the tensioning gear 105 and the tensioning gear 2 106, and one end of the gear shaft of the tensioning gear 105 is fixedly connected to a rotating rod 108.

[0037] Specifically, the fabric tensioning roller 3 and the pressure belt tensioning roller 501 have space for moving up and down in the slide groove, and the toothed plates 104 connected to the adjacent fabric tensioning rollers 3 and pressure belt tensioning rollers 501 are a group, and the tensioning gear 1 105 and the tensioning gear 2 106 are respectively meshed with the two groups of toothed plates 104. When adjusting the tension, by rotating the rotating rod 108, the tensioning gear 1 105 and the tensioning gear 2 106 are driven to rotate simultaneously by the synchronous belt 107. At this time, the two groups of toothed plates 104 will move toward each other synchronously, thereby realizing the synchronous tensioning adjustment of the composite fabric 2 and the pressure belt 5.

[0038] like Figure 5As shown, one side of the support frame 7 is fixedly connected to the corresponding limit plate 6 through a connecting portion 701, a sliding portion 702 is extended on the outer wall of the support frame 7, a sliding plate 901 slides horizontally in the sliding portion 702, a reset spring 904 is provided between the rotating frame 902 and the sliding portion 702, a sliding portion 2 703 is extended on the inner wall of the support frame 7, and a vertical gear rod 906 is installed in the sliding portion 2 703 for up and down sliding.

[0039] like Figure 6 and Figure 7 As shown, a spur rack 905 is fixedly provided at one end of the sliding plate 901 away from the rotating frame 902, and the spur rack 905 slides through the support frame 7. A rotating shaft 909 is rotatably installed in the support frame 7. The rotating shaft 909 is simultaneously perpendicular to the spur rack 905 and the vertical gear rod 906. A matching gear 1 910 and a matching gear 2 911 are fixedly sleeved on the rotating shaft 909 respectively. The bottom of the spur rack 905 is meshed with the matching gear 1 910, and one side of the vertical gear rod 906 is meshed with the matching gear 2 911.

[0040] Furthermore, an iron core 907 is fixedly provided at the top of the vertical gear rod 906 , and a power-carrying coil 908 is fixedly provided inside the support frame 7 , and the iron core 907 is coaxially inserted into the power-carrying coil 908 .

[0041] Specifically, the probe wheel 903 will always be against the surface of the composite fabric 2 under the action of the reset spring 904. When the heating temperature changes, the softening degree of the composite fabric 2 will also change accordingly. At this time, the tension applied to the probe wheel 903 will also change. The probe wheel 903 will push the sliding plate 901 to slide horizontally accordingly. The sliding plate 901 drives the spur rack 905 to move. During the displacement process, the spur rack 905 drives the rotating shaft 909 to rotate through the matching gear 1 910. The rotating shaft 909 drives the vertical gear rod 906 to slide up and down accordingly through the matching gear 2 911, thereby driving the iron core 907 to extend into or out of the energized coil 908, thereby changing the magnetic field strength generated by the energized coil 908.

[0042] It should be noted that the mating gear 1 910 in this embodiment is a small circle gear, and the mating gear 2 is a large circle gear. When the two are coaxially installed, due to the tooth ratio between the small circle gear and the large circle gear, the rotation arc length of the large circle gear is longer when rotating at the same angle, thereby effectively amplifying the displacement distance of the spur rack 905, so that when the spur rack 905 moves slightly, the vertical gear rod 906 will also be displaced accordingly, which is beneficial to improving the detection accuracy.

[0043] like Figure 6 and Figure 7As shown, the power connection component 8 also includes a pair of resistance rods 804, which are fixedly arranged inside the support frame 7. The two power connection contacts 801 are electrically connected to the power connection posts at the top of the corresponding resistance rods 804 through wires 802, and a power supply 803 is arranged on one of the wires 802, and the power supply 803 is fixedly installed on the support frame 7.

[0044] Furthermore, a metal slide plate 805 is slidably sleeved between the resistance rods 804 , and a magnetic block 806 is fixedly disposed at the bottom of the metal slide plate 805 . The magnetic block 806 is located directly above the energized coil 908 .

[0045] Specifically, when the magnetic field strength generated by the energized coil 908 changes, the magnitude of its suction force on the magnetic suction block 806 will also change accordingly. When the suction force increases, the metal slide plate 805 will be attracted to slide downward on the resistance rod 804. At this time, the resistance connected to the closed circuit increases, the current decreases, and the heating power will also decrease, thereby reducing the heating temperature. Conversely, when the suction force decreases, the resistance connected to the closed circuit decreases, the current increases, and the heating power increases, thereby increasing the heating temperature, thereby achieving the adjustment of the heating temperature.

[0046] The working principle of the present invention is as follows: Figure 1-Figure 7As shown, when in use, the composite fabric 2 enters from the feed port 101, is tensioned by the fabric tensioning roller 3, and then passes through the upper and lower hot rolling rollers 4 in sequence. The large area of ​​the composite fabric 2 is pressed against the hot rolling roller 4 by the pressing belt 5, so that both sides of the composite fabric 2 can be sufficiently heated and heated, so that both sides of the composite fabric 2 are heated evenly. When adjusting the tension, by rotating the rotating rod 108, the tensioning gear 1 105 and the tensioning gear 2 106 are driven to rotate simultaneously by the synchronous belt 107. At this time, the two sets of tooth plates 104 will move synchronously towards each other, so that the composite fabric 2 and the pressing belt 5 can be adjusted synchronously, which can not only keep the composite fabric 2 tensioned and smooth during the conveying process, but also tighten the pressing belt 5 to better exert the pressing effect. After being heated, the composite fabric 2 passes through the gap between the limit plates 6. When passing through the detection notch 601, the probe wheel 903 will always be against the surface of the composite fabric 2 under the action of the reset spring 904. When the heating temperature changes, the softening degree of the composite fabric 2 will also change accordingly. At this time, the tension applied to the probe wheel 903 will also change. The probe wheel 903 will push the sliding plate 901 to slide horizontally accordingly. The sliding plate 901 drives the spur rack 905 to move. During the displacement process, the spur rack 905 drives the rotating shaft 909 to rotate through the matching gear 1 910. The rotating shaft 909 drives the vertical gear rod 906 to slide up and down accordingly through the matching gear 2 911, thereby driving the iron core 907 to extend into or out of the energized coil 908, thereby changing the magnetic field strength generated by the energized coil 908. When the magnetic field strength generated by the energized coil 908 changes, the magnitude of its suction force on the magnetic suction block 806 will also change accordingly. When the suction force increases, the metal slide plate 805 will be attracted to slide downward on the resistance rod 804. At this time, the resistance connected to the closed circuit will increase, the current will decrease, and the heating power will also decrease, thereby reducing the heating temperature. Conversely, when the suction force decreases, the resistance connected to the closed circuit will decrease, the current will increase, and the heating power will also increase, thereby increasing the heating temperature. The heating temperature can be adjusted so that the heating temperature is always maintained in an appropriate range to meet the melting temperature requirement of the hot melt adhesive in the composite fabric 2, so as to avoid the heating temperature being too high or too low.

[0047] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
