Technical Field

[0001] The utility model relates to the field of auxiliary mechanisms for winding self-adhesive labels, in particular to an automatic label changing mechanism for self-adhesive labels. Background Art

[0002] Self-adhesive labels have the advantages of not requiring glue brushing, paste, water dipping, being pollution-free, saving labeling time, etc. compared with traditional labels. They have a wide range of applications, are convenient and fast. Self-adhesive is a kind of material, also called self-adhesive label material, which is a composite material with paper, film or other special materials as the fabric, an adhesive coated on the back, and a silicone-coated protective paper as the base paper. After being printed, die-cut and other processes, it becomes a finished label. In the production process of self-adhesive labels, a winding mechanism is needed to wind the made self-adhesive labels. When the winding roller finishes winding, an automatic label changing mechanism is needed to assist the staff in quickly replacing the winding roller.

[0003] However, the current automatic label changing mechanisms still have some deficiencies. For example, most of the existing automatic label changing mechanisms use electric push rods to push the supporting plate of the winding roller away and then use manual replacement to replace the winding roller. As a result, the staff needs to hold the winding roller all the time and keep it at a fixed height until the supporting plate holds up the winding roller, which is very likely to cause discomfort to the staff and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides an automatic label changing mechanism for self-adhesive labels. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic label changing mechanism for self-adhesive labels to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An automatic label changing mechanism for self-adhesive labels, including a bottom plate and a fixed bracket. A fixed support mechanism is fixedly installed on the top of the bottom plate, and a driving motor is installed outside the fixed support mechanism. The top of the bottom plate is slidably connected with a movable support mechanism, and a winding mechanism is movably installed inside the movable support mechanism. The fixed bracket is fixedly installed on the top of the bottom plate, and fixing plates are symmetrically installed on the front and back inner surfaces of the top of the fixed bracket. A servo motor is installed outside the fixing plates, and the output shaft of the servo motor is installed with a driving lead screw through a coupling. At the same time, an auxiliary label changing component is slidably connected to the top of the fixed bracket. Second electric telescopic rods are symmetrically installed on the front and back of the right side of the fixed bracket.

[0007] Furthermore, the mobile support mechanism includes a support plate, a T-shaped slider, a drive shaft, and a limit groove. T-shaped sliders are symmetrically installed at the front and rear of the bottom of the support plate. A drive shaft is rotatably connected inside the support plate, and a limit groove is provided at the end of the drive shaft.

[0008] Furthermore, the bottom of the support plate is fixedly connected to the top of the T-shaped slider, and the support plate and the bottom plate form a sliding structure through the T-shaped slider.

[0009] Furthermore, the winding mechanism includes a winding roller, a connecting shaft, and a clamping block. The connecting shaft is fixedly installed inside the winding roller, and clamping blocks are symmetrically and fixedly installed on the left and right sides of the connecting shaft.

[0010] Furthermore, the external dimensions of the clamping block are exactly the same as the internal dimensions of the limit groove, and the clamping block and the drive shaft form a clamping structure through the limit groove.

[0011] Furthermore, the auxiliary roll-changing assembly includes a bearing bracket, a cross-shaped slider, a connecting mechanism, a T-shaped slide bar, a first electric telescopic rod, a bearing plate, and an arc-shaped storage groove. The cross-shaped slider is fixedly installed at the bottom of the bearing bracket, the connecting mechanism is fixedly connected to the bottom of the cross-shaped slider, T-shaped slide bars are symmetrically installed on the left and right sides of the bottom of the bearing bracket, and first electric telescopic rods are symmetrically embedded and installed on the left and right sides of the top of the bearing bracket.

[0013] The utility model provides an automatic roll-changing mechanism for self-adhesive labels, which has the following beneficial effects:

[0014] 1. By setting the drive screw rod in the utility model, when the servo motor operates, it can drive the auxiliary roll-changing assembly to move back and forth along the top of the fixed bracket. After the bearing plate carries the wound winding mechanism, through the forward and backward movement of the bearing bracket, the winding mechanism of the unwound self-adhesive label automatically moves to the installation point, so that when the second electric telescopic rod contracts, it can drive the mobile support mechanism to automatically complete the installation work, thus avoiding the situation that the staff needs to hold the winding roller all the time when replacing the winding roller, resulting in sore arms or inaccurate installation positions and unable to install automatically.

[0015] 2. The utility model makes it convenient for the winding mechanism and the mobile support mechanism to be quickly disassembled and assembled through the arranged clamping blocks and limiting grooves, thus providing convenience for the automatic roll changing operation of the mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figures 1 - 3As shown in the figure, the self-adhesive label automatic roll-changing mechanism includes a bottom plate 1 and a fixed bracket 6. A fixed support mechanism 2 is fixedly installed on the top of the bottom plate 1, and a driving motor 3 is installed on the outside of the fixed support mechanism 2.

The fixed bracket 6 is fixedly installed on the top of the bottom plate 1. Fixing plates 7 are symmetrically installed on the front and rear inner surfaces of the top of the fixed bracket 6. A servo motor 8 is installed on the outside of the fixing plate 7. The output shaft of the servo motor 8 is installed with a driving lead screw 9 through a coupling. An auxiliary roll-changing assembly 10 is slidably connected to the top of the fixed bracket 6. The auxiliary roll-changing assembly 10 includes a carrying bracket 101, a cross-shaped slider 102, a connecting mechanism 103, a T-shaped slide bar 104, a first electric telescopic rod 105, a carrying plate 106, and an arc-shaped storage groove 107. A cross-shaped slider 102 is fixedly installed at the bottom of the carrying bracket 101. A connecting mechanism 103 is fixedly connected to the bottom of the cross-shaped slider 102. T-shaped slide bars 104 are symmetrically installed on the left and right sides of the bottom of the carrying bracket 101. The bottom of the carrying bracket 101 is fixedly connected to the top of the T-shaped slide bar 104. The carrying bracket 101 and the fixed bracket 6 form a sliding structure through the T-shaped slide bar 104. By setting the carrying bracket 101 and the fixed bracket 6 as a sliding structure, when the carrying bracket 101 moves back and forth along the top of the fixed bracket 6, it is more smooth and stable. At the same time, first electric telescopic rods 105 are symmetrically embedded and installed on the left and right sides of the top of the carrying bracket 101. The extending ends of the first electric telescopic rods 105 are fixedly connected to a carrying plate 106. Arc-shaped storage grooves 107 are symmetrically opened on the front and rear of the top of the carrying plate 106. Second electric telescopic rods 11 are symmetrically installed on the right side of the fixed bracket 6.

[0022] As Figures 1 - 3As shown in the figure, a fixed support mechanism 2 is fixedly installed on the top of the bottom plate 1, a driving motor 3 is installed on the outside of the fixed support mechanism 2, and a movable support mechanism 4 is slidably connected to the top of the bottom plate 1. The movable support mechanism 4 includes a support plate 41, a T-shaped slider 42, a driving shaft 43 and a limiting groove 44. T-shaped sliders 42 are symmetrically installed at the front and rear of the bottom of the support plate 41. The bottom of the support plate 41 is fixedly connected to the top of the T-shaped slider 42. The support plate 41 and the bottom plate 1 are slidably structured through the T-shaped slider 42, making the support plate 41 move more smoothly and stably along the top of the bottom plate 1. A driving shaft 43 is rotatably connected to the inside of the support plate 41, a limiting groove 44 is opened at the end of the driving shaft 43, and a winding mechanism 5 is movably installed inside the movable support mechanism 4. The winding mechanism 5 includes a winding roller 51, a connecting shaft 52 and a clamping block 53. A connecting shaft 52 is fixedly installed inside the winding roller 51, and clamping blocks 53 are symmetrically and fixedly installed on the left and right sides of the connecting shaft 52. The external dimension of the clamping block 53 is exactly the same as the internal dimension of the limiting groove 44, and the clamping block 53 and the driving shaft 43 are clamped through the limiting groove 44. By setting the clamping block 53 and the driving shaft 43 as a clamping structure, it is convenient to quickly disassemble and assemble the winding mechanism 5 and the movable support mechanism 4. A fixed bracket 6 is fixedly installed on the top of the bottom plate 1, fixing plates 7 are symmetrically installed on the inner surface of the top of the fixed bracket 6, a servo motor 8 is installed outside the fixing plates 7, the output shaft of the servo motor 8 is installed with a driving lead screw 9 through a coupling, and an auxiliary roll-changing assembly 10 is slidably connected to the top of the fixed bracket 6.

[0023] In summary, for this automatic label roll-changing mechanism, first, according to Figures 1 to 3In the structure shown in the figure, the staff places the winding mechanism 5 to be replaced on the arc-shaped storage groove 107. Then, the staff turns on the first electric telescopic rod 105 through the controller. When the first electric telescopic rod 105 starts to operate, it drives the bearing plate 106 to move upward. When the arc-shaped storage groove 107 on the top of the bearing plate 106 bears the wound winding mechanism 5, the staff turns off the first electric telescopic rod 105 and turns on the second electric telescopic rod 11. When the second electric telescopic rod 11 starts to operate, it drives the support plate 41 to move to the right along the top of the bottom plate 1 through the sliding of the T-shaped slider 42, so that the driving shaft 43 is separated from the clamping block 53. Then, the staff grabs the winding mechanism 5 and slightly pulls it to the right along the inner surface of the arc-shaped storage groove 107, so that the other end of the winding mechanism 5 is separated from the inside of the driving motor 3. Then, the staff turns on the servo motor 8 through the controller. When the servo motor 8 starts to operate, it drives the driving lead screw 9 to rotate inside the fixing plate 7. At this time, through the connection of the connection mechanism 103 and the sliding of the cross-shaped slider 102 and the T-shaped slide bar 104, the bearing bracket 101 drives the bearing plate 106 to move forward. When the winding mechanism 5 to be installed moves to the middle position between the driving motor 3 and the support plate 41, the servo motor 8 is turned off and the second electric telescopic rod 11 is turned on. When the second electric telescopic rod 11 starts to operate, it drives the support plate 41 to move inward. At this time, through the clamping block 53 being clamped into the limiting groove 44, the winding mechanism 5 is automatically installed on the inside of the mobile support mechanism 4 and the driving motor 3, so as to complete the automatic rewinding work. Then, the staff turns on the first electric telescopic rod 105 through the controller, so that the first electric telescopic rod 105 drives the bearing plate 106 to move downward. Finally, the staff removes the disassembled winding mechanism 5 and replaces it with a new winding mechanism 5 for subsequent use.
