During the movement of the threaded block 2043, the guide rod 2042 cooperates with the movement of the threaded block 2043 to guide, and the rack 2035 follows the threaded block 2043 to move synchronously.
[0039] Brief description of the use process: In the preparation of the protective film, when the jet of the mixed material is ejected, the knob 2047 can be adjusted to rotate to drive the connecting rod 2046 to rotate, and the connecting rod 2046 will drive the bevel gear 2045 to rotate, so that the bevel gear 2045 drives the bevel gear 1 2044 and the screw 2041 to rotate, and the rotation of the screw 2041 will enable the two threaded blocks 2043 to move, and the threads at both ends of the screw 2041 are designed in reverse, so that the two threaded blocks 2043 have a reverse movement trend. During the movement of the threaded block 2043, the guide rod 2042 cooperates with the movement of the threaded block 2043 for guidance, and the rack 2035 follows the threaded block 2043 to move synchronously. During the movement of the rack 2035, the linkage gear 1 2031 and the linkage gear 2 2032 will be driven to rotate respectively. The rotation of the linkage gear 1 2031 and the linkage gear 2 2032 will drive the connecting rod 1 2034 and the ring 2033 to rotate. The ring 2033 will drive the corresponding nozzle 2 2013 or nozzle 3 2014 to adjust the angle, thereby realizing the flexibility of use of nozzle 2 2013 and nozzle 3 2014, and the number of teeth of the linkage gear 2 2032 is less than the number of teeth of the linkage gear 1 2031, so that during the movement of the rack 2035, the number of rotations of the linkage gear 2 2032 is greater than the number of rotations of the linkage gear 1 2031. Thus, the angles of the second nozzle 2013 and the third nozzle 2014 can be adjusted, wherein the angle of the first nozzle 2012 is fixed, and when the second nozzle 2013 or the third nozzle 2014 is not used, the operator can also close any nozzle through the third knob 2024, further increasing the flexibility of use of the nozzle assembly 201. The rotation of the third knob 2024 will drive the fourth rod 2021 to rotate, and the fourth rod 2021 will realize the progressive movement inside the fourth embedded ring 2023 through the threaded connection, so that the fourth rod 2021 drives the fourth plug 2022 to move, and the fourth plug 2022 blocks the discharge channel 2018, which is used to control the spraying use of the first nozzle 2012, the second nozzle 2013 and the third nozzle 2014 respectively, increasing the flexibility of use of the structure. And through the arrangement of nozzle one 2012, nozzle two 2013 and nozzle three 2014, the tedious back and forth when a large area jet is required can be reduced, which is beneficial to improving the efficiency of preparing the protective film, and while increasing the nozzles, it is convenient to control and adjust the jet angle of the nozzle, and the jet range of the nozzle itself can be achieved through its own structure, which is an existing mature technology. In use, nozzle two 2013 or nozzle three 2014 can be used to control the angle and coordinate the nozzle range to ensure high efficiency in the preparation of the protective film, and when there is no need to jet a large area, the redundant nozzle components 201 can be flexibly closed, and even when a thinner protective film needs to be made, nozzle two 2013 can be closed, and the jet range of nozzle one 2012 and nozzle three 2014 can be increased to prepare a thinner protective film. This structure is flexible to use.
