Description

TECHNICAL FIELD

[0002] The polyester composite fabric refers to a fabric made of polyester fibers as the main component and processed by being compounded with other materials (such as nylon, spandex, elastic fiber, polyester film, etc.), which has the characteristics of lightness and softness, strong wear resistance, good washing resistance and various functions, and is widely used in clothing, shoe materials, luggage and home supplies, etc., and brings convenience and comfort to people's life.

[0003] Hot pressing is a conventional compounding method for the composite polyester fabric, which uses a heating roller and a pressing roller to cooperate with each other to compound the polyester coated with a molten glue layer with other fabrics.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3As shown, the application is a heating device for processing polyester composite fabric, which comprises a heating box 1 and a composite fabric 2. The heating box 1 is provided with an inlet 101 and an outlet 102 at both ends. The inlet 101 and the outlet 102 are both provided with a guide roller 103. A group of fabric tensioning rollers 3 are arranged in an upper and lower staggered manner inside the heating box 1. A group of hot pressing rollers 4 are arranged in an upper and lower staggered manner between the fabric tensioning rollers 3. The composite fabric 2 is conveyed from the inlet 101 to the outlet 102 through the corresponding fabric tensioning rollers 3 and hot pressing rollers 4. The upper part of one of the hot pressing rollers 4 is provided with a pressing belt 5. The lower part of the other hot pressing roller 4 is also provided with a pressing belt 5. The two groups of pressing belts 5 are pressed against the upper surface and the lower surface of the composite fabric 2 respectively.

[0031] Specifically, by arranging the fabric tensioning rollers 3 and the pressing belts 5, during the heating process, the composite fabric 2 enters from the inlet 101, is tensioned by the fabric tensioning rollers 3, and then passes through the two hot pressing rollers 4 in sequence. The large area of the composite fabric 2 is pressed against the hot pressing rollers 4 by the pressing belts 5, so that both sides of the composite fabric 2 can be heated sufficiently, and the heating of both sides of the composite fabric 2 is uniform. At the same time, the tensioning degree of the composite fabric 2 and the pressing belt 5 can be adjusted synchronously, which not only makes the composite fabric 2 maintain tensioning and smoothness during conveying, but also makes the pressing belt 5 tight to better exert the pressing effect.

[0032] As shown, Figures 4-7 A group of limiting plates 6 are fixedly arranged between the hot pressing rollers 4. The two limiting plates 6 are oppositely arranged with a gap. The composite fabric 2 passes through the gap between the inner walls of the limiting plates 6. The outer walls of the two limiting plates 6 are fixedly provided with support frames 7. A pair of detection grooves 601 are arranged through the limiting plates 6. The two support frames 7 are centrally symmetrically arranged and correspond to the corresponding detection grooves 601 respectively. The support frames 7 are respectively provided with an electrical connection assembly 8 and a detection assembly 9.

[0033] The electrical connection assembly 8 comprises a pair of electrical contact blocks 801. A rotating shaft 401 is coaxially arranged inside the hot pressing roller 4. A conductive ring 402 is fixedly arranged outside the rotating shaft 401. The hot pressing roller 4 is fixedly arranged outside the conductive ring 402. The hot pressing roller 4 is provided with an annular accommodating groove 403. The electrical contact blocks 801 are arranged in the annular accommodating groove 403 and are in sliding contact with the conductive ring 402.

[0034] Specifically, the hot ironing roller 4 is rotatably mounted inside the heating chamber 1 via a rotating shaft 401. During the heating process, the conductive ring 402 and the hot ironing roller 4 rotate synchronously with the rotating shaft 401. Simultaneously, the contact block 801 maintains sliding contact with the conductive ring 402 within the annular receiving groove 403, ensuring that the conductive ring 402 remains energized during rotation, thus achieving the electric heating process. In practical applications, the surface of the hot ironing roller 4 has a through groove that communicates with the annular receiving groove 403. This through groove provides space for the wire 802 connected to the contact block 801, allowing the wire 802 to slide within the through groove during rotation of the hot ironing roller 4 without becoming entangled on it.

[0035] The detection component 9 includes a sliding plate 901. A rotating frame 902 extends from one end of the sliding plate 901 near the limiting plate 6. A detection wheel 903 is rotatably installed inside the rotating frame 902. The detection wheel 903 extends into the detection slot 601 and abuts against the surface of the composite fabric 2. The detection wheel 903 drives the sliding plate 901 to move linearly to change the current in the closed circuit of the power connection component 8, thereby adjusting the heating temperature of the hot ironing roller 4.

[0036] Specifically, by setting up limiting plates 6, power-connecting components 8, and detection components 9, the composite fabric 2, after being heated, passes through the gap between the limiting plates 6. When it passes 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 degree of melting of the hot melt adhesive, the softer the composite fabric 2, and the smaller the tension effect of the detection wheel 903 against the surface of the composite fabric 2. Conversely, the same applies. Therefore, 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-connecting 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 kept within a suitable range to meet the melting temperature requirements of the hot melt adhesive inside the composite fabric 2, so as to avoid the heating temperature being too high or too low.

[0037] like Figure 1 and Figure 3 As shown, the pressing belt 5 is sleeved on the pressing belt tensioning roller 501 and a pair of fixed rollers 502. The fixed rollers 502 are set on both sides of the corresponding hot ironing roller 4. The fabric tensioning roller 3 and the pressing belt tensioning roller 501 are both equipped with sliders. The heating box 1 is longitudinally provided with grooves on both sides. The fabric tensioning roller 3 and the pressing belt tensioning roller 501 are both installed in the corresponding grooves by sliding up and down through the sliders.

[0038] Further, the outer side of the sliding block is fixedly connected with a tooth plate 104, the tooth plates 104 at the two ends of the adjacent cloth tensioning roller 3 and the pressing belt tensioning roller 501 are oppositely arranged, the two ends of the sidewall of the heating box 1 are respectively rotationally installed with a tensioning gear one 105 and a tensioning gear two 106, the two ends of the tensioning gear one 105 and the tensioning gear two 106 are respectively engaged with the corresponding tooth plate 104, a synchronous belt 107 is arranged between the gear shafts of the tensioning gear one 105 and the tensioning gear two 106, and one end of the gear shaft of the tensioning gear one 105 is fixedly connected with a rotating rod 108.

[0039] Specifically, the cloth tensioning roller 3 and the pressing belt tensioning roller 501 have an up-down moving space in the chute, the tooth plates 104 connected by the adjacent cloth tensioning roller 3 and the pressing belt tensioning roller 501 are a group, the tensioning gear one 105 and the tensioning gear two 106 are engaged with the two groups of tooth plates 104 respectively, when tensioning adjustment is performed, the rotating rod 108 is rotated, the synchronous belt 107 drives the tensioning gear one 105 and the tensioning gear two 106 to rotate at the same time, at this time, the two groups of tooth plates 104 will move synchronously towards each other, so that synchronous tensioning adjustment of the composite cloth 2 and the pressing belt 5 can be realized.

[0040] As shown in Figure 5 , one side of the support frame 7 is fixedly connected with the corresponding limiting plate 6 through a connecting part 701, a sliding part one 702 is extendedly arranged on the outer wall of the support frame 7, the sliding plate 901 slides horizontally in the sliding part one 702, a reset spring 904 is arranged between the rotating frame 902 and the sliding part one 702, a sliding part two 703 is extendedly arranged on the inner wall of the support frame 7, and a vertical gear rod 906 is slidingly installed in the sliding part two 703.

[0041] As shown in Figure 6 and Figure 7 , one end of the sliding plate 901 away from the rotating frame 902 is fixedly provided with a straight rack 905, the straight rack 905 slides through the support frame 7, a rotating shaft 909 is rotationally installed in the support frame 7, the rotating shaft 909 is perpendicular to the straight rack 905 and the vertical gear rod 906 at the same time, a matching gear one 910 and a matching gear two 911 are fixedly and sleevedly arranged on the rotating shaft 909, the bottom of the straight rack 905 is engaged with the matching gear one 910, and one side of the vertical gear rod 906 is engaged with the matching gear two 911.

[0042] Further, an iron core 907 is fixedly arranged at the top end of the vertical gear rod 906, and a power coil 908 is fixedly arranged in the support frame 7, and the iron core 907 is coaxially inserted into the power coil 908.

[0043] Specifically, the probe wheel 903 will always abut 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 acting on the probe wheel 903 will also change, the probe wheel 903 will push the sliding plate 901 to slide horizontally correspondingly, the sliding plate 901 drives the straight rack 905 to displace, the straight rack 905 drives the rotating shaft 909 to rotate through the matched gear one 910 in the displacement process, the rotating shaft 909 drives the vertical rack 906 to slide up and down correspondingly through the matched gear two 911, so as to drive the iron core 907 to extend into or withdraw from the power coil 908, so as to change the magnetic field strength generated by the power coil 908.

[0044] It should be noted that the matched gear one 910 in the embodiment is a small gear, and the matched gear two is a large gear, when the two are coaxially installed, due to the tooth ratio between the small gear and the large gear, the rotating arc length of the large gear is longer when rotating the same angle, so that the displacement distance of the straight rack 905 can be effectively enlarged, so that when the straight rack 905 slightly moves, the vertical rack 906 will also correspondingly displace greatly, which is beneficial to improve the detection precision.

[0045] As shown in Figure 6 and Figure 7 , the power connection assembly 8 further comprises a pair of resistance rods 804, the resistance rods 804 are fixedly arranged in the support frame 7, two power connection contact blocks 801 are electrically connected with the power connection columns at the top ends 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.

[0046] Further, a metal sliding plate 805 is slidably sleeved between the resistance rods 804, and a magnetic attraction block 806 is fixedly arranged at the bottom of the metal sliding plate 805.

[0047] Specifically, when the magnetic field strength generated by the power coil 908 changes, the suction force of the magnetic attraction block 806 will also change accordingly. When the suction force increases, the metal sliding plate 805 will be attracted to slide downward on the resistance rod 804, at this time the resistance in the closed circuit increases, the current becomes smaller, and the heating power also becomes smaller, so as to reduce the heating temperature, on the contrary, when the suction force decreases, the resistance in the closed circuit decreases, the current becomes larger, and the heating power also becomes larger, so as to increase the heating temperature, so as to realize the adjustment of the heating temperature.

[0048] The working principle of the present application is as follows: Figures 1-7As shown, in use, the composite fabric 2 enters from the feeding port 101, is tensioned by the fabric tensioning roller 3, and then passes the upper and lower hot pressing rollers 4 in turn. The large-area composite fabric 2 is pressed against the hot pressing roller 4 by the pressing belt 5, so that the two sides of the composite fabric 2 can be heated sufficiently and uniformly. When the tension is adjusted, the rotating rod 108 is rotated, the synchronous belt 107 drives the tensioning gear one 105 and the tensioning gear two 106 to rotate at the same time, at this time, the two sets of toothed plates 104 move synchronously towards each other, so that the synchronous tension adjustment of the composite fabric 2 and the pressing belt 5 can be realized, which not only can keep the composite fabric 2 smooth during conveying, but also can make the pressing belt 5 tight to better exert the pressing effect. After heating, the composite fabric 2 passes through the gap between the limiting plates 6, when passing through the detection notch 601, the probe wheel 903 will always abut against the surface of the composite fabric 2 under the action of the return spring 904. When the heating temperature changes, the softening degree of the composite fabric 2 will also change accordingly, at this time, the tension acting on 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 straight rack 905 to displace, the straight rack 905 drives the rotating shaft 909 to rotate through the matching gear one 910 during displacement, the rotating shaft 909 drives the vertical rack 906 to slide up and down accordingly through the matching gear two 911, so as to drive the iron core 907 to extend into or retract from the energized coil 908, so as to change the magnetic field strength generated by the energized coil 908. When the magnetic field strength generated by the energized coil 908 changes, the suction force of the magnetic suction block 806 will also change accordingly. When the suction force increases, the metal sliding plate 805 will be attracted to slide down on the resistance rod 804, at this time, the resistance in the closed circuit increases, the current becomes smaller, and the heating power also becomes smaller, so as to reduce the heating temperature, on the contrary, when the suction force decreases, the resistance in the closed circuit decreases, the current becomes larger, and the heating power also becomes larger, so as to increase the heating temperature, so as to realize the adjustment of the heating temperature, so that the heating temperature always remains in a suitable range to meet the melting temperature requirement of the hot melt adhesive in the composite fabric 2, so as to avoid that the heating temperature is too high or too low.

[0049] The above describes one embodiment of the present application in detail, but the content described is only the preferred embodiment of the present application, and cannot be considered as limiting the implementation range of the present application. Any equivalent changes and improvements made according to the application scope of the present application should still belong to the patent coverage range of the present application.
