[0032] By adopting the above technical solution, the device can quickly carry out the sand taking and winding treatment on the fabric, thereby greatly improving the practicability of the device.

[0033] In the embodiment of the present application, as Figures 1-2 shown, the adjusting mechanism includes a first motor 8 installed on one side of the mounting plate 2. The output end of the first motor 8 extends into the inner cavity of the mounting plate 2 and is fixedly connected with a lead screw 9. A lead screw nut 10 is movably connected to the outer surface of the lead screw 9. The top of the lead screw nut 10 extends above the mounting plate 2 through a sliding groove 11 and is fixedly connected with the movable plate 4.

[0034] By adopting the above technical solution, the device can quickly adjust the position of the movable plate 4 through the adjusting mechanism, so that the operator can more conveniently disassemble and assemble the sand taking sleeve 7, and thus greatly improve the sand taking efficiency of the device.

[0035] In the embodiment of the present application, as Figure 1 and Figure 4 shown, the reciprocating mechanism includes a second motor 14 installed on the outer surface of the adjusting box 1. The output end of the second motor 14 is fixedly connected with a rotating shaft 15. The other end of the rotating shaft 15 extends into the adjusting box 1 and is fixedly connected with a semi-gear disc 16. A reciprocating toothed plate 17 is meshed with the outer surface of the semi-gear disc 16. The top of the reciprocating toothed plate 17 is fixedly connected with a connecting plate 18. The top of the connecting plate 18 extends above the adjusting box 1 through an adjusting groove 19 and is fixedly connected with the mounting plate 2.

[0036] By adopting the above technical solution, the device can drive the mounting plate 2 to perform reciprocating motion through the reciprocating mechanism, so that the sand taking sleeve 7 can evenly wind the yarn fabric on the surface of the sand taking sleeve 7, and thus greatly improve the winding effect and quality of the device.

[0037] In the embodiment of the present application, as Figure 3 shown, the guiding component includes guiding grooves 12 opened on the upper and lower sides of the winding roller 6 and guiding plates 13 installed on both sides of the inner wall of the sand taking sleeve 7. The size and shape of the guiding grooves 12 are adapted to those of the guiding plates 13.

[0038] By adopting the above technical solution, the guiding groove 12 and the guiding plate 13 can not only guide but also have a certain limiting effect.

[0039] In the embodiment of the present application, as Figure 1 shown, a circular hole is formed inside the movable plate 4, and the inner diameter of the circular hole is adapted to the outer diameter of the winding roller 6.

[0040] By adopting the above technical solution, the movable plate 4 can be better separated from the winding roller 6.

[0041] In the embodiment of the present application, as Figure 3 shown, the cross-sections of the guiding groove 12 and the guiding plate 13 are both trapezoidal, and the width of the groove opening of the guiding groove 12 is smaller than the width of the groove bottom.

[0042] By adopting the above technical solution, the sand taking sleeve 7 can only move horizontally, thus greatly improving the practicability of the device.

[0043] In the embodiment of the present application, as Figure 3 shown, an anti-slip sleeve is arranged on the outer surface of the guiding plate 13, and anti-slip lines are formed on the outer surface of the anti-slip sleeve.

[0044] By adopting the above technical solution, the anti-slip sleeve can be used to increase the frictional resistance, thereby avoiding the relative sliding phenomenon.

[0045] In the embodiment of the present application, as Figure 1 shown, a controller 20 is fixedly connected to the outer surface of the adjustment box 1.

[0046] By adopting the above technical solution, the controller 20 can be used to more conveniently control the electrical appliances inside the device.

[0047] During use, the operator can first wind one end of the yarn fabric around the sand-taking sleeve 7, and then start the winding motor 5 and the second motor 14 through the controller 20. After the winding motor 5 is started, it will drive the sand-taking sleeve 7 to rotate through the winding roller 6, so that sand-taking treatment can be quickly carried out. When the second motor 14 is started, it will drive the semi-gear disc 16 to rotate through the rotating shaft 15. When the semi-gear disc 16 rotates, it will drive the reciprocating tooth plate 17 to perform left and right reciprocating movements periodically through meshing, so that the reciprocating tooth plate 17 can drive the mounting plate 2 to move left and right through the connecting plate 18, and further make the sand-taking sleeve 7 evenly wind the yarn fabric on the surface of the sand-taking sleeve 7, thus greatly improving the winding effect and quality of the device. When the winding is completed, the operator can first turn off the winding motor 5 and the second motor 14 through the controller 20, and then start the first motor 8, so that the first motor 8 drives the lead screw 9 to rotate. When the lead screw 9 rotates, it will drive the lead screw nut 10 to move horizontally under the limiting action of the chute 11, so that the lead screw nut 10 can drive the movable plate 4 to slide along the chute 11. After the movable plate 4 moves to be separated from the winding roller 6, the operator can then remove the sand-taking sleeve 7 from the winding roller 6 along the guide groove 12. Similarly, a new sand-taking sleeve 7 can be quickly installed, so that the operator can more conveniently disassemble and assemble the sand-taking sleeve 7, and thus greatly improve the sand-taking efficiency of the device.
