[0034] Through the above operations, the scraper 10 can be easily replaced.

[0035] Specifically, after using the device for a long time, the old scraper 10 will age. At this time, the rotating nut 14 can be twisted to make the rotating nut 14 rotate and disengage from the fixing bolt 13. After removing the fixing bolts 13 set at both ends of the clamping seat 6, the old scraper 10 can be slid out of the pressure groove 8.

[0036] After selecting a new scraper 10, slide the new scraper 10 into the pressure groove 8, align the positions of the fixing hole 12 and the through hole 11, insert the fixing bolt 13, and tighten the rotating nut 14 to fix the scraper 10. Through the above operations, the scraper 10 can be easily replaced, saving manpower and material resources.

[0037] In a specific embodiment, as shown in the attached Figure 1 As shown, the printing mechanism includes a moving shaft 15 arranged on the top of the inner wall of the upper box body 1, and a nozzle 16 is arranged at the bottom of the moving shaft 15.

[0038] Through the above operations, the device can eject raw materials to print clothing.

[0039] Specifically, the hydraulic rod 28 is started to lift the workbench 29 to a suitable position, and the nozzle 16 performs the 3D printing of clothing with the help of the moving axis 15.

[0040] In a specific embodiment, as shown in the attached Figure 1 , 7 As shown, the collecting mechanism includes two collecting boxes 17 arranged at the bottom of the inner cavity of the lower box body 2, a sponge 18 is arranged inside the collecting box 17, and a guide fan 19 is arranged on one side of the collecting box 17.

[0041] Through the above operation, the scraped material particles can be absorbed.

[0042] Specifically, the guide fan 19 is started, the air flow rate at the end of the collection box 17 is accelerated, and the pressure is reduced, so that the air flow drives the waste debris to move into the collection box 17 and is finally filtered by the sponge 18.

[0043] In a specific embodiment, as shown in the attached Figure 3 , 4 As shown, both ends of the bottom of the rubber strip 7 are fixedly connected to guide rods 24, and the inner wall of the lower box body 2 is fixedly connected to two guide strips 25, and the guide strip 25 is arranged at the bottom of the threaded rod 4. A corrugated through groove 26 is opened on the guide strip 25, and the guide rod 24 is slidably connected to the through groove 26. A baffle 27 is fixedly connected to one side of the guide strip 25.

[0044] Through the above operation, the scraping effect of the scraper 10 and the rubber strip 7 can be improved, and it is ensured that the through groove 26 will not be blocked.

[0045] Specifically, the guide rod 24 at the bottom of the rubber strip 7, under the guidance of the wavy through groove 26, causes the rubber strip 7 to scrape against the surface of the workbench 29, thereby improving the cleaning effect of the rubber strip 7 on the workbench 29. When there are many material particles on the surface of the workbench 29, the baffle 27 can prevent the accumulated material particles from overflowing into the guide strip 25 when the sliding strip 5 is working, blocking the through groove 26, thereby affecting the sliding of the guide rod 24 and ensuring the normal operation of the scraping mechanism.

[0046] Working principle of the utility model: firstly, the hydraulic rod 28 is started to lift the workbench 29 to a suitable position, and the nozzle 16 performs the work of 3D printing clothing with the help of the moving shaft 15. At this time, the specific progress of 3D printing can be observed through the observation window 31 of the upper box body 1;

[0047] After the 3D printing work is completed, the hydraulic rod 28 is started to drive the workbench 29 to move down to a suitable position inside the lower box 2 through the lifting port 3, and the motor 20 is started. The motor 20 drives one of the threaded rods 4 to rotate. Under the meshing transmission of the bevel gear cylinder 21 and the transmission rod 22, the other threaded rod 4 realizes synchronous rotation. The rotation of the two threaded rods 4 drives the sliding bar 5 threadedly connected to the surface of the threaded rod 4 to move horizontally. The rubber strip 7 at the lower end of the sliding bar 5 generates friction with the upper end of the workbench 29. The scraper 10 is tightly attached to the upper end of the workbench 29 under the elastic force of the spring 9. Through horizontal movement, the waste adhered to the workbench 29 is scraped off with the assistance of the baffle 27, and the waste falls from the workbench 29 to the inside of the collection box 17;

[0048] At the same time, under the guidance of the wavy through groove 26, the guide rod 24 at the bottom of the rubber strip 7 causes the rubber strip 7 to rub against the surface of the workbench 29, thereby improving the cleaning effect of the rubber strip 7 on the workbench 29;

[0049] While the motor 20 is working, the guide fan 19 is started, the air flow velocity at the end of the collection box 17 is accelerated, and the pressure is reduced, so that the air flow drives the waste debris to move into the collection box 17, and finally is filtered by the sponge 18. After the guide fan 19 finishes working, the hinged rotating door 30 of the lower box body 2 is opened, and the collection box 17 can be directly taken out for cleaning;

[0050] After working for a period of time, the old scraper 10 will age. At this time, the hinged rotating door 30 of the lower box body 2 can be opened, and the rotating nut 14 can be twisted to make the rotating nut 14 rotate and disengage from the fixing bolt 13. After removing the fixing bolts 13 set at both ends of the clamping seat 6, the old scraper 10 can be slid out of the pressure groove 8, and the scraper 10 can be removed;

[0051] After selecting a new scraper 10, slide the new scraper 10 into the pressure groove 8, align the positions of the fixing hole 12 and the through hole 11, insert the fixing bolt 13, and tighten the rotating nut 14 to fix the scraper 10. Through the above operations, the scraper 10 can be easily replaced, saving manpower and material resources.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
