[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A coating device for fabrics, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the device includes a body 1 and a fixing rod 3 welded inside the body 1 for fixing several nozzles 2. A rotating roller 4 is welded inside the body 1 and located directly below the fixing rod 3. The fabric to be coated passes over the rotating roller 4. The fixedly connected rotating roller 4 prevents it from rotating under the tension of the fabric, ensuring the stable use of the structure on the rotating roller 4. Several receiving grooves 5 are formed on the outer peripheral wall of the rotating roller 4. A limiting piece 6, which abuts against the fabric, is slidably connected within the receiving groove 5. The limiting piece 6 is located between adjacent nozzles 2 and at the farthest end of the spray range of the nozzle 2. Therefore, when the fabric can cover the limiting piece 6, it ensures complete coating of the fabric by the nozzle 2. A supplementary head 7 is fixedly connected to the fixing rod 3 between adjacent nozzles 2. The spray range of the supplementary head 7 is smaller than that of the nozzle 2. When the width of the fabric to be sprayed is wide enough to cover one limiting plate 6 but not the second, the fabric between the two limiting plates 6 cannot come into contact with the paint flowing from the nozzle 2. Therefore, the supplementary head 7 can be used to coat the part of the fabric that cannot come into contact with the paint. By limiting the spraying range of the supplementary head 7, the uneven coating caused by the overlap of the spraying range of the supplementary head 7 and the nozzle 2 can be avoided. The limiting plate 6 and the nozzle 2 are electrically connected through receiver 1. Receiver 2, which is electrically connected to the supplementary head 7, is fixedly connected to the rotating roller 4. The number of receivers 1 and 2 covered by the fabric is the same as the number of nozzles 2 and supplementary heads 7 that are opened. This allows different numbers of nozzles 2 and supplementary heads 7 to be opened according to different fabric widths, ensuring the flexibility of coating setup and the comprehensiveness of the coating.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, receiver one includes a transmitter 8 fixedly connected to the limiting plate 6 and a receiver 9 fixedly connected to the bottom surface of the fixing rod 3. Receiver one is configured as a light sensor. A control panel 10 is fixedly connected to the side wall of the body 1. The control panel 10 is connected to several receivers 9 via Bluetooth. Receiver two includes a transmitter 11 fixedly connected to the outer peripheral wall of the rotating roller 4 and a receiver 12 fixedly connected to the bottom surface of the fixing rod 3. Receiver two is also configured as a light sensor. Receiver 12 is electrically connected to the supplementary head 7 via a connecting cable. Receiver one and receiver two are controlled separately. In the initial state, the distance between transmitter 8 and receiver 9 is relatively far. When the device starts working, the distance between transmitter 8 and receiver 9 is relatively far. At this time, the light emitted by transmitter 8 cannot be received by receiver 9. When the limiting plate 6 moves upward, the light emitted by transmitter 8 can be received by receiver 9. The distance between the feeder 8 and the receiver 9 is reduced, allowing the receiver 9 to receive the signal sent by the sender 8 and display it on the control panel 10. The control panel 10 then opens the nozzle 2 corresponding to the receiver 9 that did not receive the signal. The control panel 10 cannot control the supplementary head 7 corresponding to the receiver 12. The signal sent by the sender 11 fixed on the rotating roller 4 can be directly received by the receiver 12. Therefore, when fabric covers the sender 11, the signal sent by the sender 11 cannot be received by the receiver 12. At this time, the supplementary head 7 opens to spray paint. Since the rotating roller 4 is welded to the machine body 1, the receiving groove 5, the sender 8, and the sender 11 are all located at the top of the rotating roller 4, so that the fabric can stably contact the sender 8 and the sender 11 when passing over the rotating roller 4.

[0022] like Figure 1 and Figure 5 As shown, the longitudinal cross-sectional shape of the nozzle 2 outlet is fan-shaped. The range of paint sprayed by the nozzle 2 is increased by setting the cross-sectional shape. The cross-sectional shape of the supplementary head 7 is rectangular. The supplementary head 7 is located at the midpoint of the line connecting adjacent nozzles 2. The setting of the position and cross-sectional shape of the supplementary head 7 ensures that the spraying range of the paint from the supplementary head 7 is reduced, avoiding unevenness of the coating surface caused by repeated coating. A receiving box 19 with the same position as the rotating roller 4 is placed on the bottom surface of the machine body 1. Due to the different widths of the fabric, there may be situations where the fabric cannot cover the spraying range of the supplementary head 7 or the nozzle 2. At this time, the excess paint will fall into the receiving box 19. This method avoids paint being sprayed onto the ground, causing paint waste and environmental pollution.

[0023] like Figures 1-5As shown, a sliding groove 13 is provided along the length of the rotating roller 4. A through groove 14 communicating with the sliding groove 13 is provided on the bottom surface of the receiving groove 5. A push rod 15 is slidably connected in the sliding groove 13. The top surface of the push rod 15 is bonded to the bottom surface of the limiting piece 6 by an elastic element 16, which is a spring. The push rod 15 drives several limiting pieces 6 to rise or fall simultaneously, ensuring the convenience of the structure during use. One end of the push rod 15 extends out of the rotating roller 4, and a telescopic rod 17 is welded to the other end of the push rod 15 extending out of the rotating roller 4. A slot 18 for the telescopic rod 17 to be engaged is provided on the side wall of the machine body 1. The bottom surface of the slot 18 is higher than the bottom surface of the sliding groove 13. In the initial state, the push rod 15 is located on the bottom surface of the sliding groove 13. At this time, the limiting piece 6 and the sending piece 8 are both located in the receiving groove 5, avoiding When the sending component 8 and the limiting piece 6 protrude out of the receiving groove 5, causing the fabric to bulge upon contact with the sending component 8, the worker applies a pulling force to the telescopic rod 17 to move it upwards as the fabric passes through the rotating roller 4. Due to the tension of the fabric surface, the sending component 8, which is in contact with the fabric, will be subjected to pressure from the tension of the fabric surface and move downwards. At this time, the elastic element 16 will undergo compression deformation, ensuring that the limiting piece 6 and the sending component 8 remain within the receiving groove 5, thus preventing the structure from protruding out of the receiving groove 5 and causing fabric deformation. The telescopic rod 17 and the push rod 15 are fixed to the machine body 1 by the slot 18 to prevent the push rod 15 from sliding under its own weight. The sliding limiting piece 6 ensures that the fabric is limited, preventing the fabric from shifting out of the spraying range.

[0024] Working principle: In the initial state, transmitter 1 8 and transmitter 2 11 are located in the receiving groove 5. Due to the large distance between transmitter 1 8 and receiver 1 9, the light emitted by transmitter 1 8 cannot be received by receiver 1 9. After the fabric passes through the rotating roller 4, the worker turns on the equipment to start working. First, the extension rod 17 applies a pulling force to the push rod, causing it to slide in the sliding groove 13 and lock into the slot 18. Transmitter 1 8 covered by the fabric is unable to pass through the receiving groove 5 due to the pressure of the fabric. Transmitter 1 8 not covered by the fabric will move upward so that the light emitted by it can be received by receiver 1 9. Receiver 2 12 is connected separately to the supplement head 7. Therefore, the light emitted by transmitter 2 11 can be directly received by receiver 2 12. After the fabric covers several transmitters 1 8 and transmitter 2 11, receivers 1 9 and receiver 2 12, which cannot receive signals, can drive the nozzle 2 and supplement head 7 to apply adhesive, thereby achieving stable coating of fabrics of different widths.

All technical solutions falling within the scope of this utility model's concept are protected.
