[0003] At present, when carbon fiber fabrics are digitally sprayed, the dust and particles remaining on the surface of the fabric are easily adhered to the surface of the fabric and sprayed together with the spraying. When the dust particles fall off later, the paint on the sprayed part of the fabric surface is lost and the spraying effect of the fabric is affected. Therefore, it is necessary to design a practical spraying device for fiber composite materials. Summary of the invention

[0006] The dust cleaning and collecting mechanism comprises a long scraper, the outer wall of the long scraper contacts the inner wall of the box, the inner wall of the box is fixedly connected with a collecting plate, the top of the long scraper is fixedly connected with a spring, one end of the spring is fixedly connected with a fixing plate, the outer wall of the fixing plate is fixedly connected with the inner wall of the box, the outer wall of the long scraper is fixedly connected with a magnetic block A, the outer wall of the magnetic block A contacts with a magnetic block B, the outer wall of the magnetic block B is fixedly connected with the inner wall of the box, and a scraping and dust blowing mechanism is arranged outside the long scraper;

[0007] I The scraping and blowing mechanism includes a slider, the outer wall of the long scraper is provided with a slot B and a slot A, the outer wall of the slider is slidably connected to the top of the long scraper through the slot A, and the outer wall of the slider is fixedly connected with a fixed block;

[0008] According to the above technical solution, the scraping and blowing mechanism includes a limiting sleeve, the inner wall of the limiting sleeve is provided with a square groove, the outer wall of the fixed block is slidably connected to the inner wall of the limiting sleeve through the square groove, the bottom of the square groove is fixedly connected to the top of the scraper, the outer wall of the scraper is slidably connected to the outer wall of the long scraper through the card groove B, the outer wall of the long scraper is fixedly connected with an air bag, and the bottom of the air bag is fixedly connected with a jet pipe.

[0012] According to the above technical solution, the roller A contacts the inner wall of the box body and has friction.

[0013] According to the above technical solution, the long scraper is V-shaped when viewed from above.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] (1) The present invention provides a dust collection mechanism. When the fabric is scraped by the long scraper, the long scraper itself has a V-shaped top view. Therefore, after the dust on the fabric is scraped by the long scraper, it will continuously roll to the two sides of the long scraper along the inclined surface of the outer wall of the long scraper, and fall off the fabric and onto the collection plate, so that the dust is concentratedly separated and collected, thereby avoiding the problem of dust being present for a long time between the bottom of the long scraper and the fabric, causing the granular dust to continuously roll and wear on the surface of the fabric, thereby protecting the quality of the fabric itself and avoiding scratches caused by long-term scraping and cleaning.

[0016] (2) The present invention sets a dust collection mechanism. When the cloth is stretched, it pushes the bottom of the long scraper and pushes the long scraper upward. The long scraper squeezes the spring on the top to deform it. The long scraper is used to press and scrape the surface of the fabric in real time, thereby improving the cleaning effect of the fabric before it passes through the digital spray machine and avoiding dust, residue particles on the surface of the fabric that affect the spraying effect of the digital spray machine. The long scraper is pushed upward after the cloth is stretched, thereby adapting to the tension of different fabrics and avoiding the situation where the scraping force is too strong when the fabric is stretched and scraped by the long scraper, thereby wearing the surface of the fabric.

[0017] (3) The present invention provides a dust cleaning and collecting mechanism. When the fabric is scraped by the long scraper, the long scraper itself has a V-shaped top view. Therefore, after the dust on the fabric is scraped by the long scraper, it will continuously roll to the two sides of the long scraper along the inclined surface of the outer wall of the long scraper, and fall off the fabric and onto the collecting plate, so that the dust is concentratedly separated and collected, thereby avoiding the problem of dust existing for a long time between the bottom of the long scraper and the fabric, which causes the dust particles to continuously roll and wear on the surface of the fabric. The quality of the fabric itself is protected, and scratches caused by long-term scraping and cleaning are avoided.

[0018] (4) The present invention provides a scraping and blowing mechanism. When the slider slides to the middle position of the top of the long scraper, it will hit the air bag on the top of the long scraper, and the air inside the air bag will be squeezed and ejected through the jet pipe and the internal one-way valve A. At this time, air is blown to the scraper surface that slides to the middle position of the bottom of the long scraper, so as to blow away the dust scraped by the scraper, and prevent the dust from being pushed by the scraper and accumulating and adhering to itself, thereby affecting the cleaning effect of the subsequent sliding scraping of the scraper.

[0029] The scraping and blowing mechanism 4 includes a limiting sleeve 403, the inner wall of the limiting sleeve 403 is provided with a square groove 404, the outer wall of the fixed block 402 is slidably connected with the inner wall of the limiting sleeve 403 through the square groove 404, the bottom of the square groove 404 is fixedly connected with the top of the scraper 405, the outer wall of the scraper 405 is slidably connected with the outer wall of the long scraper 301 through the card groove B409, the outer wall of the long scraper 301 is fixedly connected with an air bag 406, and the bottom of the air bag 406 is fixedly connected with a jet pipe 407.

[0030] An air hole is opened on the top of the air bag 406 , a one-way valve A is fixedly connected to the inside of the air jet tube 407 , a one-way valve B is fixedly connected to the inside of the air hole, and the inside of the air hole is communicated with the inside of the air jet tube 407 .

[0031] The top of the long scraper 301 is in an inclined shape with a higher middle and gradually descending on both sides.

[0032] The magnetism between the magnet block A305 and the magnet block B306 is that opposite poles attract each other, and the outer wall of the airbag 406 is made of rubber material and has elasticity.

[0033] The roller A1 contacts the inner wall of the box body 2 and has friction.

[0034] The long scraper 301 is V-shaped when viewed from above;

[0035] When in use, the textile fabric of the fiber composite material is placed into the roller A1 from the left side of the roller A1, and then pulled out from the right side of the roller A1. The two rollers A1 are fitted and clamped to each other, and then the fabric is pulled through the bottom of the long scraper 301, and passes between the base 8 and the digital spray machine 7, and is placed inside the two rollers B6, and pulled out from the right side of the roller B6, and then the motor 5 is started to drive the rotating shaft 9 and the roller B6 to start rotating, so as to transmit the fabric, and then the digital spray machine 7 is started to digitally spray the fabric;

[0036] As the fabric is continuously transported, when it passes between the two rollers A1, the outer wall of roller A1 will be subject to the friction of the inner wall of box 2, thereby limiting the rotation of roller A1. Therefore, when the fabric passes between rollers A1, there will be resistance. When roller B6 drives the fabric to be transported, the fabric between rollers A1 and B6 will be tightened.

[0037] When the fabric is stretched tight, it pushes the bottom of the long scraper 301, pushing the long scraper 301 upward, and the long scraper 301 squeezes the spring 303 on the top to deform it, and the long scraper 301 is used to press and scrape the fabric surface in real time, thereby improving the cleaning effect of the fabric before it passes through the digital spraying machine 7, and avoiding dust, residue particles, etc. on the fabric surface that affect the spraying effect of the digital spraying machine 7. In addition, by pushing the long scraper 301 upward after the fabric is stretched tight, it can adapt to the stretched state of different fabrics, and avoid the situation that the fabric surface is worn due to the large scraping force when the fabric is stretched and scraped by the long scraper 301;

[0038] When the fabric is slid and scraped by the long scraper 301, the long scraper 301 itself is in a V-shape when viewed from above. Therefore, after the dust on the fabric is scraped by the long scraper 301, it will continuously roll to the two sides of the long scraper 301 along the inclined surface of the outer wall of the long scraper 301, and fall off the fabric and onto the collecting plate 302, so that the dust is concentratedly separated and collected, thereby avoiding the problem of dust particles constantly rolling and wearing on the surface of the fabric due to the dust existing between the bottom of the long scraper 301 and the fabric for a long time, thereby protecting the quality of the fabric itself and avoiding scratches caused by long-term scraping and cleaning;

[0039] When the long scraper 301 is pushed up by the tightened fabric, the magnetic block A305 on the outer wall of the long scraper 301 will be pushed by the fabric until the fabric is continuously tightened, and the magnetic attraction between the magnetic block A305 and the magnetic block B306 is smaller than the force of the fabric pushing the long scraper 301, so that the magnetic block A305 on the outer wall of the long scraper 301 is separated from the magnetic attraction between the magnetic block B306, and the long scraper 301 is quickly pushed up by the force of the tightened fabric, and vibrates for a short period of time under the elastic force of the spring 303, so as to shake off the dust adhered to the outer wall of the long scraper 301 that has been placed for a long time;

[0040] When the long scraper 301 rises and vibrates rapidly, the top of the long scraper 301 is an inverted V-shape when viewed from the front, with low heights on both sides of the top of the long scraper 301 and high heights in the middle of the top of the long scraper 301. Therefore, when the long scraper 301 rises rapidly, the slider 401 will slide to both sides of the top of the long scraper 301 due to its own inertia, and when the long scraper 301 rises and the squeezing spring 303 stops compressing and starts to rebound, the long scraper 301 starts to fall, and at this time, the slider 401 instead maintains its previous upward inertia, and slides on the inclined surface of the top of the long scraper 301 to approach the middle of the top of the long scraper 301;

[0041] When the slider 401 slides through the fixed block 402 and slides in the square groove 404 inside the limiting sleeve 403 and drives the limiting sleeve 403 and the scraper 405 to move synchronously, the scraper 405 slides inside the card slot B409 to limit the scraper 405. Therefore, as the slider 401 slides and rises on the top of the long scraper 301 and approaches the middle of the top of the long scraper 301, it can also drive the scraper 405 to slide horizontally on the inner wall of the card slot B409 synchronously, thereby sliding and scraping the outer wall of the long scraper 301. When the fabric is tightened, the surface of the long scraper 301 is automatically slid and scraped. When the surface of the long scraper 301 that has been placed for a long time starts to be fully scraped and cleaned, the cleaning of the long scraper 301 is ensured, and the scraping efficiency of the subsequent fabric passing through is further improved.

[0042] When the slider 401 slides to the middle position at the top of the long scraper 301, it will hit the airbag 406 at the top of the long scraper 301, and the air inside the airbag 406 will be squeezed and ejected through the jet pipe 407 and the internal one-way valve A, blowing air to the surface of the scraper 405 that slides to the middle position at the bottom of the long scraper 301 at the same time, blowing away the dust scraped by the scraper 405, and preventing the dust from being pushed by the scraper 405 and then accumulating and adhering to itself, thereby affecting the cleaning effect of the subsequent sliding scraping of the scraper 405.
