[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This application provides a technical solution: a hot stamping printing winding mechanism, including a winding roller 1 and a base plate 2 disposed below the winding roller 1. Limiting rotation grooves 3 are respectively opened on the outer walls of both sides of the winding roller 1. A cavity 6 is opened on the inner wall of the winding roller 1. An air pump 10 is installed on the outer wall of one side of the winding roller 1. A pressure relief pipe 4 is fixedly installed on the outer wall of the winding roller 1 away from the air pump 10. A pressure relief valve 5 is installed on the outer wall of the pressure relief pipe 4. Multiple sets of cross holes 7 are opened on the outer wall of the winding roller 1 located between the two limiting rotation grooves 3, and each set of cross holes 7 communicates with the cavity 6. The inner wall of the winding roller 1 located inside each set of cross holes 7 is slidably connected with a king-shaped movable block 8. A sleeve 11 is slidably sleeved on the outer wall of the winding roller 1. A drive mechanism for rotating the winding roller 1 is respectively provided on both sides of the winding roller 1.

[0032] In the technical solution of this application, by sliding the sleeve 11 into the outer wall of the take-up roller 1, the air pump 10 can inflate the cavity 6, and then the gas pushes the king-shaped movable block 8 to slide in the cross hole 7. The king-shaped movable block 8 inside the sleeve 11 can abut against the inner wall of the sleeve 11, increasing its friction and preventing the sleeve 11 from moving. The king-shaped movable block 8 on the outer side of the sleeve 11 will move fully, so that the king-shaped movable block 8 can limit the left and right sides of the sleeve 11, further preventing the axial movement of the sleeve 11 and enhancing the take-up quality of the hot stamping printing material by the sleeve 11.

[0033] In the technical solution of this application, such as Figure 6 As shown, the inner wall of the take-up roller 1 is engraved with a scale 9, which can be used to adjust the installation position of the sleeve 11.

[0034] In the technical solution of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, side frames 12 are fixedly installed on the upper ends of both sides of the base plate 2. Top frames 13 are hinged to the outer walls above the two side frames 12. The base plate 2 can fix the side frames 12, while the top frames 13 can be flipped on the upper end of the side frames 12, which facilitates the loading and unloading of the take-up roller 1. The drive mechanism includes two sets of limiting rotating wheels 22. Each set of limiting rotating wheels 22 corresponds to the limiting rotating groove 3, and each set of limiting rotating wheels 22 is in contact with the outer wall of the take-up roller 1. The rotation of the limiting rotating wheels 22 can drive the take-up roller 1 to rotate under the cooperation of friction. Each set of top frames 13 and the inner wall of the side frames 12 are respectively provided with movable grooves 14, and each set of limiting rotating wheels 22 is located inside the movable groove 14. Each set of limiting rotating wheels 22 is rotatably installed in the inner wall of the side frames 12 and the top frames 13. The top frames 13 and the side frames 12 can provide rotational support for the limiting rotating wheels 22.

[0035] In the technical solution of this application, such as Figure 2 As shown, iron blocks 20 are fixedly installed on the outer wall of one side of each set of top frames 13. Electromagnets 21 are installed on the outer wall of each set of side frames 12 located below the iron blocks 20. The electromagnets 21 are magnetically connected to the iron blocks 20. The top frame 13 can fix the iron blocks 20, while the side blocks can fix the electromagnets 21. The attraction between the electromagnets 21 and the iron blocks 20 can position and attract the top frame 13 and the side frames 12.

[0036] In the technical solution of this application, such as Figure 2 As shown, one of the limiting rotating wheels 22 is fixedly connected to a driven pulley 15. A motor bracket 19 is fixedly installed on the outer wall of the side frame 12 located below the driven pulley 15. A torque motor 18 is installed on the upper end of the motor bracket 19. A driving pulley 16 is fixedly installed on the output shaft of the torque motor 18. The outer walls of the driving pulley 16 and the driven pulley 15 are tensioned with the same belt 17. The motor bracket 19 can fix the torque motor 18, and the torque motor 18 can drive the driving pulley 16 to rotate. The driving pulley 16 can drive the driven pulley 15 to rotate with the belt 17. Then the driven pulley 15 can drive one of the limiting rotating wheels 22 to rotate.

[0037] In use, the magnetic attraction between electromagnet 21 and iron block 20 is released, and then the take-up roller 1 is removed. The sleeve 11 is then placed on the outer wall of the take-up roller 1, and the position of the sleeve 11 is determined by the scale 9. With the cooperation of the upper limit rotation groove 3 of the take-up roller 1, it is positioned corresponding to the limit rotation wheel 22. Then, the top frame 13 is flipped, causing electromagnet 21 and iron block 20 to attract again, thus positioning the top frame 13 and side frame 12. The air pump 10 then pressurizes the cavity 6, and the pressure causes the king-shaped movable block 8 to move within the cross hole 7, thus opening the sleeve 11. The movable block 8 can abut against the inner wall of the sleeve 11 to enhance its friction and prevent the sleeve 11 from moving. The movable block 8 on the outer side of the sleeve 11 will move fully, so that the movable block 8 can limit the left and right sides of the sleeve 11, further preventing the axial movement of the sleeve 11 and enhancing the winding quality of the hot stamping printing material. When the sleeve 11 is finished winding, the cooperation of the pressure relief pipe 4 and the pressure relief valve 5 can conveniently relieve the pressure inside the cavity 6. The movable block 8 can move easily in the cross hole 7, and then the sleeve 11 can slide and unload easily.
