This device sprays and dries the surface assistants on both sides of the curtain fabric in different regions through corresponding spraying mechanisms, effectively avoiding the problem that it is difficult to control the spraying accuracy when spraying the surface assistants on both sides of the curtain fabric simultaneously, and avoiding the problem that the surface assistants are easily adhered to the guide rollers due to unreasonable drying design. However, the surface of the curtain fabric is relatively rough and prone to accumulating dust before processing.

Detailed implementation manners

[0034] In order to clearly and completely describe the purpose, technical solutions of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 12, the present invention provides a surface assistant spraying device for curtain fabric production, including a frame 1, a front-end cleaning device 3 and a material spraying device 4. The interior of the frame 1 forms two vertically connected processing cavities 13. Between the two processing cavities 13, a first guiding shaft 11 and a second guiding shaft 10 for carrying the curtain fabric 12 are arranged from top to bottom. At the end of the processing cavity 13 in the lower layer, a third roller pair 6 for clamping and driving the movement of the curtain fabric 12 is provided. The first guiding shaft 11 and the second guiding shaft 10 are used to change the movement direction of the curtain fabric 12 and tension the curtain fabric 12. The first guiding shaft 11 and the second guiding shaft 10 are installed on the frame 1 through bearings.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10, the front-end cleaning device 3 includes a connecting frame 303 installed at the end of the processing cavity 13 located on the upper layer. A first roller pair 301 and a second roller pair 305 for clamping and driving the movement of the curtain 12 are installed on the connecting frame 303. A pair of cleaning shafts 302 for cleaning the dust on the curtain cloth 12 are arranged between the first roller pair 301 and the second roller pair 305. A power device 8 for driving the movement of the cleaning shaft 302 is arranged on the frame 1. A third motor 14 for driving the first roller pair 301, the second roller pair 305, and the third roller pair 6 to move is arranged on the frame 1. A brush piece 306 for cleaning the surface of the curtain cloth 12 is fixedly installed on the cleaning shaft 302. The cleaning shaft 302 is installed between the connecting frame 303 through bearings. The first roller pair 301, the second roller pair 305, and the third roller pair 6 are all composed of a pair of metal shafts for clamping the curtain cloth 12 and capable of rotating. Rubber sleeves or anti-slip patterns for increasing the friction with the curtain cloth 12 can also be provided on the metal shafts according to the needs of use. The metal shafts located in the first roller pair 301, the second roller pair 305, and the third roller pair 6 are respectively connected to the output end of the third motor 14 through gears or belts and are driven by the third motor 14 to rotate. When the curtain cloth 12 enters the front-end cleaning device 3, it will be clamped and tensioned by the first roller pair 301 and the second roller pair 305. Then the curtain cloth 12 is wound around the first guiding shaft 11 and its movement direction is changed by the first guiding shaft 11. Then the curtain cloth 12 is wound around the second guiding shaft 10 and its direction is changed by the second guiding shaft 10. Then the curtain cloth 12 enters the processing cavity 13 located on the lower layer and is clamped by the third roller pair 6. When the third motor 14 works, it will drive the metal shafts in the first roller pair 301, the second roller pair 305, and the third roller pair 6 to rotate, so as to drive the curtain cloth 12 to pass through the two processing cavities 13 by these metal shafts. During the movement of the curtain cloth 12, the cleaning shaft 302 will also be driven by the power device 8 and start to rotate. The cleaning shaft 302 will use the brush piece 306 on its own surface to scrape the surface of the curtain cloth 12, so that the dust and impurities on the surface of the curtain cloth 12 are cleaned off. And because the distance between the first roller pair 301 and the second roller pair 305 is generally set not to exceed fifty centimeters, the curtain cloth 12 between the first roller pair 301 and the second roller pair 305 will be in a good tension state. At this time, the brush piece 306 on the cleaning shaft 302 can effectively contact every corner of the surface of the curtain cloth 12 to achieve efficient scraping, so as to avoid the situation that the folds or pattern areas on the curtain cloth 12 cannot be well scraped due to poor tension effect, resulting in poor dust removal effect. Moreover, the curtain cloth 12 in a good tension state can also provide good resilience, so as to use the elasticity of the curtain cloth 12 to bounce the dust and impurities on the surface of the curtain cloth into the air, further improving the cleaning effect of the dust and impurities on the surface of the curtain cloth 12.Specifically, in order to further improve the scraping effect of the cleaning shaft 302, the brush pieces 306 on the cleaning shaft 302 can be inserted into the surface of the cleaning shaft 302 in the form of metal inserts protruding from the surface of the cleaning shaft 302, and bristles are arranged on the surface of the metal inserts. The brush pieces 306 themselves are arranged in a circumferential array of at least three on the cleaning shaft 302, and there is a gap between adjacent brush pieces 306. In this way, a height difference is formed between the end of the metal insert and the surface of the cleaning shaft 302. When the cleaning shaft 302 rotates, the surface of the cleaning shaft 302 and the end of the brush piece 306 will pass through the same position on the curtain fabric 12. However, due to the height difference formed between the surface of the cleaning shaft 302 and the end of the brush piece 306, the curtain fabric 12 will deform in this area, and during the deformation process, the dust and impurities on the surface of the curtain fabric 12 will be ejected into the air by relying on its own elastic force, so as to achieve a better cleaning effect.

[0037] Please refer to Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the power device 8 includes a mounting bracket 805 fixedly installed on the frame 1, and a second motor 802 is fixedly installed on the mounting bracket 805. A first gear 806 is driven by the output end of the second motor 802. A second gear 803 is rotatably installed on the mounting bracket 805, and a third gear 801 is coaxially installed on the second gear 803. A docking gear 304 meshing with the third gear 801 is coaxially fixed on the cleaning shaft 302. The output end of the second motor 802 can drive the second gear 803 to rotate through the first gear 806, and the second gear 803 can drive the coaxially installed third gear 801 to rotate. The third gear 801 can drive the docking gear 304 to rotate, and the docking gear 304 can drive the coaxially installed cleaning shaft 302 to rotate. In this way, the purpose of driving the cleaning shaft 302 to move through the second motor 802 is achieved. By adjusting the rotation speed of the second motor 802, the rotation speed of the cleaning shaft 302 can be adjusted, so that the cleaning shaft 302 can clean the dust and impurities on the surface of the curtain fabric 12 at an appropriate speed.

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 11, spraying devices 4 for spraying surface auxiliaries onto the curtain fabric 12 are respectively arranged in the upper and lower processing cavities 13, and the two spraying devices 4 respectively perform spraying operations on both sides of the curtain fabric 12. The spraying device 4 includes a connection housing 402 fixedly installed on the frame 1, and a spraying cavity 405 is formed inside the connection housing 402. A second pair of interfaces 403 for threading the curtain fabric 12 into the spraying cavity 405 are arranged on the connection housing 402. A diversion box 404 is arranged on the connection housing 402, and the inside of the diversion box 404 is connected to an external surface auxiliary supply device through a supply pipe 407. A spray nozzle 406 that communicates with the inside of the diversion box 404 and is used for spraying surface auxiliaries onto the curtain fabric 12 located in the spraying cavity 405 is arranged on the diversion box 404. The diversion box 404 is slidably installed in the connection housing 402 through a guide rail, and a linear motor 401 is fixedly installed on the connection housing 402. The output end of the linear motor 401 is connected to the diversion box 404 and is used for driving the diversion box 404 to reciprocate. Taking the upper and lower end faces of the curtain fabric 12 when it just enters the first roller pair 301 as the upper surface and the lower surface, when the curtain fabric 12 enters the upper processing cavity 13, the spraying device 4 inside the upper processing cavity 13 is used for spraying the upper surface of the curtain fabric 12. When the curtain fabric 12 changes direction after passing through the first guide shaft 11 and the second guide shaft 10 and enters the lower processing cavity 13, the lower surface of the curtain fabric 12 will be flipped to the upward position. At this time, the spraying device 4 inside the lower processing cavity 13 is used for spraying the lower surface of the curtain fabric 12. In this way, the spraying operations on the upper and lower surfaces of the curtain fabric 12 can be staggered, thereby avoiding mutual interference. When the spraying device 4 is operating, first, the curtain fabric 12 is in a state of being threaded into the spraying cavity 405 through the second pair of interfaces 403. At this time, the corresponding surface auxiliaries are sent into the inside of the diversion box 404 by an external surface auxiliary supply device through the supply pipe 407. Subsequently, the surface auxiliaries located inside the diversion box 404 will be sprayed onto the surface of the curtain fabric 12 by the spray nozzle 406. According to the usage requirements, an atomization device can also be arranged on the spray nozzle 406 to atomize the surface auxiliaries and then spray them onto the surface of the curtain fabric 12.When the surface agent is sprayed on the surface of the curtain fabric 12 by the spray nozzle 406, the linear motor 401 will also drive the diversion box 404 to perform a reciprocating linear motion, so that each spray nozzle 406 can spray reciprocally within a certain range, thereby eliminating the area that cannot be sprayed between the nozzles, effectively improving the spraying uniformity. In addition, since the spraying process is carried out inside the spray chamber 405, and the connecting housing 402 is in a sealed state at other positions except for the second pair of interfaces 403 for the curtain fabric 12 to enter and exit, the sprayed surface agent is difficult to leave the spray chamber 405 even if it does not adhere to the surface of the curtain fabric 12, thus avoiding the risk of a large amount of surface agent leaking into the air, and it is also convenient to collect the residual surface agent directly through the bottom of the spray chamber 405 and then process it uniformly.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 12 ,upper and lower processing cavities 13 are respectively provided with drying devices 5 for drying the curtain fabric 12 at the outlet ends corresponding to the corresponding spray devices 4. The drying device 5 includes a drying box 511 fixedly installed on the frame 1, and the drying box 511 is provided with a third pair of interfaces 516 for the curtain fabric 12 to pass through. An infrared heater 512 for heating the curtain fabric 12 is fixedly installed in the inner cavity of the drying device 5. After the spray device 4 sprays the surface agent on the surface of the curtain fabric 12, in order to enable the surface agent to quickly and firmly bond with the curtain fabric 12, it is necessary to use the drying device 5 to dry the surface agent on the surface of the curtain fabric 12. Therefore, an upper and lower processing cavity 13 needs to be provided with a drying device 5 at the outlet end corresponding to the corresponding spray device 4 for drying work. When the curtain fabric 12 enters the drying box 511 from the third pair of interfaces 516, the infrared heater 512 inside the drying box 511 will use infrared rays to heat the surface agent adhering to the surface of the curtain fabric 12, thereby accelerating the curing of the surface agent, and effectively avoiding the problems that the surface agent is not completely cured and is prone to falling off or is unevenly distributed after being subjected to extrusion pressure.

[0040] The surface agent spraying device for curtain fabric production provided by this embodiment can use the front cleaning device 3, the third roller pair 6, the first guide 11 and the second guide 10 to tension the curtain fabric 12, then clean the surface of the curtain fabric 12 through the cleaning shaft 302, and then spray and dry both sides of the curtain fabric 12 through the spray device 4 and the drying device 5, thereby avoiding the influence of dust and impurities, and having a high equipment integration degree, a small floor area, being easier to operate and more stable, solving the problems that the existing curtain fabric surface spraying equipment lacks a cleaning device and cannot guarantee the spraying effect, and at the same time has a low integration degree, and can effectively improve the spraying quality of the curtain fabric and the equipment is easier to operate.

[0041] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 12, on the basis of the first embodiment, a first intake housing 502 and a first exhaust housing 513 are fixedly installed on the drying box 511. A first intake fan blade 501 is rotatably installed in the first intake housing 502, and a first exhaust fan blade 514 is rotatably installed in the first exhaust housing 513. The first exhaust fan blade 514 and the first intake fan blade 501 are respectively fixedly installed at both ends of the same rotating shaft 507, and a driven wheel 508 is coaxially fixed in the middle of the rotating shaft 507. A first motor 510 is fixedly installed on the drying box 511, and a driving wheel 509 engaged with the driven wheel 508 is installed at the output end of the first motor 510. A return chamber 515 for collecting the gas inside the drying box 511 is arranged inside the drying box 511, and the return chamber 515 is communicated with the first exhaust housing 513. At least two unit heating boxes 504 are arranged in an array inside the drying box 511, and heating coils 505 are arranged inside the unit heating boxes 504. The unit heating boxes 504 blow hot air to the curtain fabric 12 through the blowing pipes 506, and all the unit heating boxes 504 are jointly communicated with the first intake housing 502 through the air distribution pipe 503. When the first motor 510 works, it can drive the first intake fan blade 501 and the first exhaust fan blade 514 to work simultaneously through the rotating shaft 507. Thus, the first intake fan blade 501 is used to draw external air into the first intake housing 502, and then it is sent into each unit heating box 504 through the air distribution pipe 503. Then these gases are heated by the heating coils 505 and then sent into the interior of the drying box 511 to dry the curtain fabric 12. Subsequently, these gases enter the return chamber 515, and when the first exhaust fan blade 514 rotates, it will draw the gas in the return chamber 515 into the first exhaust housing 513 and then discharge it from the first exhaust housing 513. In this way, not only can the surface auxiliaries on the surface of the curtain fabric 12 be heated by hot air to accelerate the drying speed, but also the volatile substances generated by the surface auxiliaries during the drying process can be taken away from the interior of the drying box 511 by the flowing hot air, thus avoiding problems such as precipitation caused by the long-term accumulation of these volatile substances in the drying box 511 and affecting the normal operation of the drying device 5. On the other hand, the entire drying process is completed inside the drying box 511, and the side of the curtain fabric 12 that does not need to be dried is in contact with and tensioned by the third docking port 516. In this way, it can effectively prevent the disturbance of the hot air flowing inside the drying box 511 to the area of the curtain fabric 12 outside the drying box 511, thus avoiding the shedding of the surface auxiliaries on the surface of the curtain fabric 12 caused by the shaking of the curtain fabric and ensuring the effect of coating and drying the surface auxiliaries.In this way, only one first motor 510 is required as the power component to achieve the intake and exhaust inside the drying box 511. Therefore, the control process is simpler and the equipment integration degree is higher. It further solves the problems of the existing curtain fabric surface spraying equipment lacking a cleaning device and being unable to guarantee the spraying effect, as well as the low integration degree. It can effectively improve the spraying quality of the curtain fabric and make the equipment easier to operate.

The second bevel gear 903 is coaxially installed with the second exhaust fan blade 902 and is used to drive the second exhaust fan blade 902 to rotate. When the cleaning shaft 302 is working, the dust and impurities on the surface of the curtain fabric 12 will be brushed into the air by the brush pieces 306 on the cleaning shaft 302 and thus fill the inner cavity of the diversion housing 204. When the second motor 802 is working, it will also directly drive the second air intake fan blade 702 to rotate, so that external air is drawn into the second air intake housing 701 by the air intake fan blade. Then, this air is sent from the inside of the second air intake housing 701 into the air jet nozzles 203 through the air inlet pipe 205, and then sprayed into the inner cavity of the diversion housing 204 by the air jet nozzles 203. At the same time, the second motor 802 will also drive the second bevel gear 903 to rotate through the first bevel gear 804, so as to drive the second exhaust fan blade 902 to rotate by using the second bevel gear 903. The second exhaust fan blade 902 draws the gas inside the diversion housing 204 into the second exhaust housing 901 through the exhaust pipe 201. At this time, the dust and impurities inside the diversion housing 204 will also be drawn into the second exhaust housing 901. Then, these dust and impurities will be sent out of the second exhaust housing 901 along with the air flow, thus ensuring that the dust and impurities will not accumulate in the diversion housing 204 for a long time and fall back onto the curtain fabric 12, and in this way, the cleaning effect on the curtain fabric 12 can be further improved.In this way, only one second motor 802 is needed as the power component to simultaneously complete the air supply and air extraction inside the diversion housing 204, and it can also be used to drive the cleaning shaft 302 to clean the surface of the curtain fabric 12. Therefore, the usage amount of the power component is reduced, the integration degree of the device is improved, and at the same time, the control method becomes simpler, making the working reliability of the device higher. Further, it solves the problems that the existing spraying device for the curtain fabric surface lacks a cleaning device and cannot guarantee the spraying effect, and has a low integration degree, and can effectively improve the spraying quality of the curtain fabric and make the device easier to operate.

[0043] Embodiment 4: On the basis of Embodiment 3, the present invention further provides a usage method of a surface auxiliary agent spraying device for curtain fabric production, including the following steps:

[0044] Step 1: First, pass the curtain fabric 12 through the correct positions of the first roller pair 301, the cleaning shaft 302, and the second roller pair 305 in sequence. Then, pass the curtain fabric 12 through the spraying device 4 and the drying device 5 in the upper processing cavity 13 in sequence, and then wind the curtain fabric 12 around the first guiding shaft 11 and the second guiding shaft 10 in sequence. Subsequently, pass the curtain fabric 12 through the spraying device 4 and the drying device 5 in the lower processing cavity 13 in sequence, and then pass the curtain fabric 12 through the correct position of the third roller pair 6.

[0045] Step 2: After the curtain fabric 12 is installed, turn on the first motor 510, the second motor 802, the third motor 14, and the linear motor 401. At the same time, set the heating coil 505 and the infrared heater 512 to the working state. Subsequently, the corresponding surface auxiliary agent can be provided by an external surface auxiliary agent supply device. At this time, the curtain fabric 12 will move at a constant speed under the traction of the first roller pair 301, the second roller pair 305, and the third roller pair 6. During the movement of the curtain fabric 12, the cleaning shaft 302 will clean the dust and impurities on the surface of the curtain fabric 12, and at the same time, cooperate with the air intake device 7 and the exhaust device 9 to discharge these dust and impurities. Meanwhile, the spraying device 4 will spray the surface auxiliary agent onto the surface of the curtain fabric 12, and then the drying device 5 will cure the surface auxiliary agent onto the surface of the curtain fabric 12.

[0046] Step 3: After the curtain fabric 12 is sent out by the third roller pair 6, use an external winding device to wind up the curtain fabric 12.
