The left end of the reel 3 is coaxially keyed to a transmission disk 32, and a transmission groove 322 for the transmission block 184 to be plugged in is provided at the center of the transmission disk 32, and a plurality of recessed holes 321 for the protrusion 183 to be plugged in are provided on the circumference of the transmission groove 322.

[0035] Furthermore, a groove 12 is formed on the top of the base 1, in which a screw rod 13 is rotatably mounted. The end of the screw rod 13 passes through the base 1 and is coaxially keyed to a handwheel 131. The screw rod 13 is coaxially keyed to a connecting seat 15, which is fixedly connected to a bracket 16 via bolts. The rotation of the screw rod 13 facilitates the horizontal movement of the bracket 16, thereby facilitating the connection and fixation of the connecting plate 18 to the transmission plate 32. This design facilitates the disassembly and assembly of the reel 3 and the rotation of the reel 3.

[0036] In this embodiment, a horizontally arranged pull plate 23 is fixed at the connection between the connecting block 24 and the limiting plate 22. A pull hole is formed at the front end of the pull plate 23. The arrangement of the pull plate 23 and the pull hole facilitates the horizontal movement of the limiting plate 22, thereby facilitating the assembly and disassembly of the reel 3.

[0037] In this embodiment, the connecting disc 18, connecting shaft 181, transmission shaft 182, protrusion 183, and transmission block 184 are integrally formed, and are all made of galvanized steel. The integrally formed connecting disc 18, connecting shaft 181, transmission shaft 182, protrusion 183, and transmission block 184 have the advantage of high connection strength, ensuring the structural strength of the connecting disc 18, connecting shaft 181, transmission shaft 182, protrusion 183, and transmission block 184, which facilitates stable rotation of the reel 3.

[0038] In this embodiment, the cross-sectional shapes of the transmission block 184 and the transmission slot 322 are both regular hexagonal, while the cross-sectional shapes of the protrusion 183 and the recessed hole 321 are both circular. This design facilitates the rotation of the transmission plate 32 by the rotation of the connecting plate 18, and facilitates stable transmission between the connecting plate 18 and the transmission plate 32.

This design facilitates a stable connection between the connecting disc 18 and the transmission disc 32 for better transmission.

[0040] In this embodiment, two limit rings 31 are coaxially keyed at both ends of the reel 3, and the two adjacent limit rings 31 are respectively clamped on the left and right sides of the bracket 21. The limit rings 31 limit the reel 3 and prevent it from shaking in the bracket 211.

[0041] In this embodiment, connecting rods 14 are fixed on both sides of the groove 12. The connecting rods 14 pass through the connecting seat 15 and are slidably connected to the connecting seat 15. The arrangement of the connecting rods 14 guides the horizontal movement of the connecting seat 15, ensuring the stability and smoothness of the horizontal movement of the connecting seat 15.

[0042] It will be appreciated that the motor 19 in this embodiment is a speed-adjustable motor. A speed-adjustable motor is a motor capable of adjusting its speed as needed. This motor achieves higher performance by varying the number of magnetic pole pairs, voltage, current, frequency, and other factors. The following is a detailed description of the speed-adjustable motor: In this embodiment, this speed-adjustable motor facilitates adjustment of the speed of the spool 3 to achieve stable retraction and unwinding of the label roll.

[0043] It should be added that the bottom of the bracket 211 in this embodiment is arc-shaped. This design facilitates the outer wall of the reel 3 to fit with the bottom of the bracket 211 , thereby facilitating the stable and smooth rotation of the reel 3 inside the bracket 211 .

[0044] It is worth noting that the motor 19 involved in this embodiment is an existing conventional technology and will not be described in detail here.

[0045] Before use, the user first pulls the pull plate 23 to the front side, and the pull plate 23 drives the limit plate 22 and the connecting block 24 to move to the front side. The spring 26 is compressed by the connecting block 24. When the limit plate 22 is separated from the top of the bracket 211, the user places the two ends of the reel 3 into the bracket 211 and clamps the limit ring 31 on both sides of the bracket 21. Then the user releases the pull plate 23. Under the elastic action of the spring 26, the limit plate 22 is reset and moves to the top of the bracket 211 , blocked by the limit plate 22, the reel 3 cannot escape from the bracket 211; then the user rotates the handwheel 131, and the handwheel 131 drives the screw rod 13 to rotate. As the screw rod 13 rotates, the connecting seat 15 moves horizontally and drives the bracket 16 to move horizontally. The bracket 16 also drives the reducer 17 and the motor 19 to move horizontally. When the transmission block 184 is inserted into the transmission groove 322 and the protrusion 183 is inserted into the concave hole 321, the user stops rotating the handwheel 131. At this time, the reel 3 is installed.

[0046] During specific use, the user first turns on the power of the motor 19, and the motor 19 starts to work. The output shaft of the motor 19 rotates to drive the input end of the reducer 17 to rotate. The output end of the reducer 17 rotates synchronously and drives the connecting disk 18, the connecting shaft 181, the transmission shaft 182, the protrusion 183 and the transmission block 184 to rotate synchronously. At this time, the transmission disk 32 rotates synchronously and drives the reel 3 to rotate. As the reel 3 rotates, the label roll can be reeled and unwound.

[0047] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
