[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the utility model proposes a tension dynamic balancing mechanism for the unwinding process of a self-adhesive label, comprising a base plate 1, and a guide assembly 2 installed on the base plate 1 to guide the label tape. The guide assembly 2 comprises a positioning plate 21, a first guide roller 22, and a second guide roller 23. Four groups of positioning plates 21 are arranged in pairs and symmetrically and installed on the top of the base plate 1, and the position of the positioning plates 21 is fixed. A group of first guide rollers 22 and a group of second guide rollers 23 are rotatably connected in two opposite groups of positioning plates 21, so that the first guide rollers 22 and the second guide rollers 23 keep rotating in place. The second guide roller 23 is arranged on the side where the two groups of first guide rollers 22 are away from each other, and the position of the first guide roller 22 is higher than the position of the second guide roller 23. The two groups of first guide rollers 22 are at the same height, and the two groups of second guide rollers 23 are at the same height, so that the label tape between the two groups of second guide rollers 23 remains in a horizontal state, which is convenient for adjusting the tension. The label tape passes through the surfaces of the first group of first guide rollers 22, the first group of second guide rollers 23, the second group of second guide rollers 23, and the second group of first guide rollers 22 in sequence. The position where the label tape passes through the first guide roller 22 and the second guide roller 23 is a Z-shaped structure, which is convenient for tightening the label tape.

[0034] For further information, see Figure 1 and Figure 3The above-mentioned balancing mechanism also includes a belt pressing assembly 3 in contact with the label tape, and the belt pressing assembly 3 includes a moving frame 31 and an adjusting roller 32. The moving frame 31 is U-shaped and is arranged between the two sets of second guide rollers 23. The adjusting roller 32 is rotatably connected to the moving frame 31. The adjusting roller 32 rotates in the moving frame 31 while remaining in position. The adjusting roller 32 contacts the label tape, so that the label tape drives the adjusting roller 32 to rotate when it moves. An adjusting mechanism 4 is used to drive the belt pressing assembly 3 to adjust the tension of the label tape. The adjusting mechanism 4 includes a mounting frame 41, a servo motor 42, and a moving box 43. The mounting frame 41 in an L-shaped arrangement is fixedly connected to the top of the bottom plate 1, and the position of the mounting frame 41 is fixed. The servo motor 42 is installed on the top of the mounting frame 41, and the position of the servo motor 42 is also fixed. The output end of the servo motor 42 passes through the mounting frame 41 and is fixedly connected to the moving box 43. The servo motor 42 is used to drive the moving box 43 to move up and down, thereby adjusting the position of the adjusting roller 32, and then adjusting the tension by pressing the adjusting roller 32 on the label tape. The moving box 43 is hollow, and the adjustment mechanism 4 further includes a limiting rod 44 and a limiting cylinder 45. Two sets of limiting rods 44 are symmetrically arranged on both sides of the servo motor 42 and one end is fixedly connected to the moving box 43. The limiting rods 44 move synchronously when the moving box 43 moves. The other end of the limiting rod 44 penetrates the mounting frame 41. The two sets of limiting cylinders 45 are installed on the top of the mounting frame 41 and are slidably sleeved on the outer ring of the limiting rod 44. The moving box 43 moves smoothly through the limiting action of the limiting rod 44 and the limiting cylinder 45, so that the belt pressing assembly 3 moves smoothly.

[0035] Furthermore, Figure 1 and Figure 4As shown, the above-mentioned balancing mechanism also includes a dynamic sensing component 5 for controlling the belt pressing component 3 to adjust, and the adjusting mechanism 4 is connected to the belt pressing component 3 through the dynamic sensing component 5. The dynamic sensing component 5 includes a connecting rod 51, a limiting plate 52, a pressing plate 53, and a spring 54. Multiple groups of connecting rods 51 are equidistantly arranged and fixedly connected to the top of the mobile frame 31. The number of connecting rods 51 is more than two groups, which is convenient for the smooth movement of the mobile frame 31. The connecting rods 51 move synchronously with the mobile frame 31. The limiting plate 52 is slidably connected in the mobile box 43. The ends of the multiple groups of connecting rods 51 away from the mobile frame 31 all penetrate the mobile box 43 and are fixedly connected to the limiting plate 52. The pressing plate 53 is smoothly slidably connected to the mobile box 43 through the multiple groups of connecting rods 51, and the pressing plate 53 prevents the mobile frame 31 from falling downward. The pressing plate 53 is also slidably connected in the pressing plate 53, and the pressing plate 53 is arranged on the side of the limiting plate 52 away from the connecting rod 51. Multiple groups of springs 54 are arranged between the limit plate 52 and the pressure plate 53 and one end is fixedly connected to the pressure plate 53. The springs 54 are used to release elastic force to squeeze the pressure sensor 55 after being compressed. The dynamic sensing component 5 also includes a pressure sensor 55 and a controller 56. Multiple groups of pressure sensors 55 are installed on the side of the pressure plate 53 away from the limit plate 52, and the pressure sensor 55 is fixedly connected to the moving box 43. The pressure sensor 55 is used to sense the elastic force of the spring 54 and then determine the tension of the label tape. The controller 56 is installed on the top of the bottom plate 1. The servo motor 42 and the pressure sensor 55 are both electrically connected to the controller 56. The controller 56 controls the length of the servo motor 42 to be extended according to the pressure sensed by the pressure sensor 55, so as to realize dynamic adjustment of the tension of the label tape.

[0036] In this embodiment, the label tape on the label roll is firstly stretched so that it contacts the surfaces of the first group of first guide rollers 22, the first group of second guide rollers 23, the second group of second guide rollers 23, and the second group of first guide rollers 22 in sequence, and one end of the label tape is connected to the traction mechanism to realize the traction of the label tape. At this time, the servo motor 42 is started, and the output end of the servo motor 42 is stretched to drive the moving box 43 to move downward, so that the adjusting roller 32 moves downward and presses on the surface of the label tape to bend the label tape. Since there is a certain tension on the label tape, when the adjusting roller 32 presses the label tape downward, the label tape goes back to support the adjusting roller 32 upward, and at this time, the moving frame 31, the adjusting roller 32, the connecting rod 51, and the limit plate 52 stop moving downward, and the moving box 43 continues to move downward, thereby driving the pressing plate 53 to move downward and compressing the spring 54 between it and the limit plate 52, and at this time, the elastic force of the spring 54 will push the pressing plate 53 to press the pressure sensor 55 upward, and the pressure sensor 55 transmits the pressure sensed by the controller 56. At the same time, when the servo motor 42 continues to extend, the greater the pressure sensed by the pressure sensor 55, the greater the tension of the label tape. When the controller 56 determines that the tension of the label tape is appropriate through the pressure sensor 55, the servo motor 42 stops, and the tension of the label tape is in the best state. At the same time, during the movement of the label tape, the tension may change, so that the pressure sensed by the pressure sensor 55 changes. The controller 56 adjusts the servo motor 42, and the servo motor 42 contracts to drive the moving box 43 to move upward to reduce the tension, and the servo motor 42 extends to drive the moving box 43 to move downward to increase the tension, thereby achieving a dynamic balance of the tension.

[0037] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
