At this time, the fourth bevel gear 19 will rotate under the driving of the first driven wheel 20. Since the fourth bevel gear 19 is engaged with the third bevel gear 16, the fourth bevel gear 19 will drive the rotating shaft 15 to rotate through the third bevel gear 16.

[0045] The front surface of the support 1 is fixedly provided with a drying box 26, the inside of the drying box 26 is provided with a heating wire 27, the outer surface of the heating wire 27 is fixedly sleeved with the support 1 and the inside of the drying box 26 respectively, the bottom end of the drying box 26 is fixedly provided with a base 28, and the bottom end of the base 28 is fixedly connected with the outer surface of the support 1.

[0046] Due to the design of the heating wire 27, heat is generated when the heating wire 27 operates, and due to the design of the base 28, the drying box 26 can be well supported.

[0047] The inside of the top end of the drying box 26 is movably sleeved with a supporting shaft 29, the top end of the outer surface of the supporting shaft 29 is fixedly sleeved with a second driven wheel 30, and the bottom end of the outer surface of the supporting shaft 29 is fixedly sleeved with a fan blade 31.

[0048] Due to the movably sleeving of the supporting shaft 29 with the inside of the top end of the drying box 26, when the second driven wheel 30 rotates, the fan blade 31 is driven to rotate through the supporting shaft 29, and due to the design of the fan blade 31, when the fan blade 31 rotates, the heat generated by the heating wire 27 can be blown to the label in the inside of the drying box 26, so that the label can be quickly dried.

[0052] Due to the design of the dust cover 37, good dustproof effect can be achieved.

[0053] The working principle and use process of the utility model are as follows:

[0054] First, the operator will be respectively set in two roll two shaft 2 outer surface, then the operator on the roll 3 push so that the roll 3 along the shaft 2 outer surface backward movement, when the back of the roll 3 in the round plate 38 adhesion, at this point the positioning block 39 will be set in the back of the roll 3 inside, due to the design of the positioning block 39, will be connected to the roll 3 and shaft 2 play a good positioning effect, then the operator on the twist block 10 twist, this time the round bar 4 will be driven by the twist block 10 rotation, at the same time the threaded block 5 will be driven by the round bar 4 rotation, due to the threaded block 5 outer surface and the internal thread of the extrusion block 6 set, thus when the threaded block 5 rotation will drive the extrusion block 6 movement, this time the movable block 7 will be driven by the extrusion block 6 along the shaft 2 inside movement, due to the shaft 2 inside the movable block 7 limit, so that the extrusion block 6 can only drive the movable block 7 forward and backward movement, this time the extrusion block 6 will drive the movable block 7 backward movement, in this process the extrusion block 6 will be four clamping block 8 extrusion, make four clamping block 8 along the shaft 2 outer surface inside outward movement, this time four clamping block 8 will be in the outward movement on four spring 9 stretch, due to the design of the four spring 9, will be four clamping block 8 movement play a good reset effect, then the outer surface of the four clamping block 8 will be in the outward movement in the roll 3 inside, this time four clamping block 8 will be on the roll 3 movement block, in turn on the roll 3 play locking effect, so that the shaft 2 and roll 3 complete connection, so as to realize the function of convenient for roll disassembly.

[0055] Then the operator guides the label on the unwinding roller 3 to the winding roller 3, at this time the outer surface of the label will be in contact with the two guide rollers 25 and the two printing rollers 17 respectively, due to the design of the two guide rollers 25, the label will be well guided, then the operator starts the driving motor 11, at this time the vertical shaft 12 will simultaneously drive the first bevel gear 13 and the first driving wheel 22 to rotate, since the outer surface of the first bevel gear 13 is meshed and connected with the outer surface of the second bevel gear 14, when the first bevel gear 13 rotates, it will drive the second bevel gear 14 to rotate, at this time the second bevel gear 14 will drive the rotating shaft 2 as a whole to rotate, so that the winding roller 3 winds the label, at the same time, the first driving wheel 22 will drive the first driven wheel 20 to rotate through the first transmission belt 23, at this time the two fourth bevel gears 19 will rotate around the fixed shaft 21 under the drive of the first driven wheel 20, since the outer surfaces of the two fourth bevel gears 19 are meshed and connected with the outer surfaces of the two third bevel gears 16 respectively, when the two fourth bevel gears 19 rotate, they will drive the two third bevel gears 16 to rotate, at the same time, the two third bevel gears 16 will drive the two printing rollers 17 to rotate through the two rotating shafts 15, when the printing rollers 17 rotate, they will dip the paint in the ink cartridge 18 and apply it to the label, thereby realizing the function of automatically printing the label during winding.

[0056] When the label is printed, the operator starts the heating wire 27 at this time, the heating wire 27 will generate heat, then the operator powers on the motor 33, at this time the short shaft 34 will drive the second driving wheel 35 to rotate, then the second driving wheel 35 will drive the three second driven wheels 30 to rotate simultaneously through the second transmission belt 36, at this time the three second driven wheels 30 will drive the three fan blades 31 to rotate through the three supporting shafts 29, at this time the three fan blades 31 will blow the heat generated by the heating wire 27 to the label, so that the paint on the label dries quickly, thereby realizing the function of automatically drying the label, due to the design of the dust cover 37, it can well filter dust.
