At the same time, the elastic force generated by the deformation of the reset spring a9 gives the central shaft 7 a leftward thrust to reset it. Two groups of notches 10 are provided on the outer wall of the central shaft 7, and a slide groove a11 is provided on the inner wall of the shell a5. The outer wall at the notch 10 is slidably connected with the inner wall of the slide groove a11. Originally, the slide groove a11 was staggered with the notch 10 of the central shaft 7, so that it was fixed on the shell a5, but the central shaft 7 can be pulled to the right to move it to the right, so that the notch 10 is realigned with the slide groove a11. At this time, the central shaft 7 can be removed together with the coating roller 8, which is convenient for maintenance or replacement of the coating roller 8.

[0024] See also Figure 1 and Figure 3The outer wall above the workbench 1 is slidably connected to a shell b12, and the inner wall of the shell b12 is elastically connected to a pressing assembly through a return spring b15. The pressing assembly includes a pressing plate 14, one end of the return spring b15 is fixedly connected to the inner wall at the top of the shell b12, and the other end of the return spring b15 is fixedly connected to the outer wall above the pressing plate 14. The pressing plate 14 can be lifted to place the fabric under the pressing plate 14, and then the return spring b15 pushes the pressing plate 14 down to press the fabric. A guide rod 16 is passed through and slidably connected to the inner wall of the shell b12. The bottom of the guide rod 16 is fixedly connected to the outer wall above the pressing plate 14. The guide rod 16 can ensure that the pressing plate 14 will not deviate during the lifting and lowering process. A pull rod 13 is passed through and slidably connected to the inner wall of the shell b12. The outer wall above the pressing plate 14 is fixedly connected to the bottom end of the pull rod 13. Pulling the pull rod 13 upward can drive the pressing plate 14 to lift. After releasing it, the return spring b15 pushes it down to press the fabric. The inner wall of the shell b12 is elastically connected to a return rod 17 through a return spring c18. One end of the return spring c18 is fixedly connected to the inner wall of the shell b12, and the other end of the return spring c18 is fixedly connected to the top of the return rod 17. The return rod 17 can be pressed downward to move it downward and reset at the same time.

After adjusting the shell b12 to a suitable position, release the reset rod 17, and the reset spring c18 pushes it to reset, so that the slider 19 slides back into the limit groove 20.

[0025] Working principle: Place the fabric on the workbench 1. When fabrics of different specifications need to be compressed, press the reset rod 17 downward to make the slider 19 slide out of the limit groove 20, and then the outer shell b12 can be slid along the outer wall of the workbench 1, and the slider 19 slides along the slide groove b6. After adjusting to the appropriate position, release the reset rod 17, and the reset spring c18 pushes it to reset, so that the slider 19 is re-engaged in the limit groove 20, and then the pull rod 13 is pulled upward to control the pressing plate 14 to compress the fabric. When it is necessary to replace the coating roller 8 of different specifications and sizes, pull the central axis 7 to the right until the notch 10 is aligned with the slide groove a11, slide the central axis 7 along the slide groove a11, and remove the coating roller 8. After replacing it to the appropriate specifications, align the notch 10 with the slide groove a11 and slide it into it. Then, the elastic force generated by the deformation of the reset spring a9 pushes the central axis 7 to move to the left, so that the notch 10 is staggered with the slide groove a11. Replacement and disassembly are relatively convenient, and maintenance is convenient.
