Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the PVC film coater for convenient feeding of the present invention includes a coating table 1, a coating device 2 is provided on the coating table 1, a feeding assembly is provided at the front end of the coating table 1, the feeding assembly includes a positioning frame 4, a first clamping assembly and a second clamping assembly, two limit blocks 5 are symmetrically arranged on the inner wall of the positioning frame 4, a plurality of unwind reels 3 are sequentially placed on the positioning frame 4, circular plates 10 are fixedly arranged at both ends of the unwind reel 3, and limit grooves 11 matching with the limit blocks 5 are provided on the circular plates 10. The first clamping assembly and the second clamping assembly are both located at the bottom of the positioning frame 4, and the first clamping assembly is located above the second clamping assembly. The first clamping assembly includes two symmetrically arranged first thrusters 6, and a first clamping block 7 for limiting the circular plate 10 is provided at the output end of the first thruster 6. The second clamping assembly includes two symmetrically arranged second thrusters 8, and a second clamping block 9 for limiting the circular plate 10 is provided at the output end of the second thruster 8. An arc-shaped plate is provided at the bottom end of the positioning frame 4, and no limit block 5 is provided on the inner wall of the arc-shaped plate, and two positioning shafts 17 are rotatably arranged at the bottom of the arc-shaped plate, and the positioning shafts 17 can limit the circular plate 10 inside the arc-shaped plate;

[0024] A plurality of limit holes 12 are provided inside the circular plate 10 at one end of the unwind reel 3. A third thruster 13 is fixedly arranged on one side of the positioning frame 4. A base is provided at the output end of the third thruster 13. A motor 14 is provided on the base. A turntable 15 is provided at the output end of the motor 14. An insertion rod 16 passing through the arc-shaped plate and inserted into the limit hole 12 is provided on the turntable 15;

[0025] When this structure is in use, the wound unwind reels 3 are sequentially placed into the positioning frame 4. At this time, through the cooperation of the limit block 5 and the limit groove 11, the plurality of unwind reels 3 can be prevented from rotating in the positioning frame 4;

[0026] Through the two second clamping blocks 9, the unwinding shaft 3 at the bottom of the positioning frame 4 can be limited. Through the two first clamping blocks 7, the second unwinding shaft 3 from the bottom of the positioning frame 4 can be limited. After starting the motor 14, the inserting rod 16 can drive the circular plate 10 to rotate, and then the unwinding shaft 3 can rotate between the two arc-shaped plates. At this time, the circular plate 10 can be limited by the positioning shaft 17, which can improve the stability of the circular plate 10 during rotation, and enable the unwinding shaft 3 to unwind the fabric. As the unwinding shaft 3 unwinds, the coating device 2 can coat the PVC film on the fabric. The arc-shaped plate and the positioning frame 4 are of an integral structure;

[0027] When the material on the unwinding shaft 3 is coated, start the third thruster 13 to make the motor 14 pull the inserting rod 16 to move, so that the inserting rod 16 is pulled out from the limiting hole 12, and then the unwinding shaft 3 can be taken out between the two arc-shaped plates. At this time, start the second thruster 8 to make the two second clamping blocks 9 no longer limit the circular plate 10, so that the unwinding shaft 3 at the bottom of the positioning frame 4 can enter between the two arc-shaped plates, and then make the two second clamping blocks 9 reset. Move the two first clamping blocks 7, and at this time, multiple unwinding shafts 3 will descend as a whole. Here, the shapes of the first clamping block 7 and the second clamping block 9 are not specified, and they can be rectangular or cylindrical. Further start the third thruster 13 to reset the motor 14 and the turntable 15, so that the inserting rod 16 can be inserted into the limiting hole 12. Since there is no limiting block 5 inside the arc-shaped plate, the unwinding shaft 3 can be temporarily rotated to fine-tune the circular plate 10. When loading the unwinding shaft 3, not much manual participation is required, which can not only save labor but also have high loading efficiency.

[0028] In this structure, the limiting groove 11 is rectangular, and the inserting rod 16 is of a cylindrical structure.

[0029] In this structure, the first thruster 6, the second thruster 8 and the third thruster 13 adopt telescopic cylinders, and the motor 14 adopts a servo motor.

[0030] Furthermore, the positioning frame 4 is fixed above the coating table 1 through a support rod, and the bottom of the support rod is fixed to the upper end of the coating table 1 by screws. The screw fixing method has the advantage of convenient assembly and can make the positioning frame 4 easy to assemble.
