DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: an automatic self-adhesive label peeling device, comprising a device body 1; characterized in that: a reeling roller 4 is rotatably mounted on the top of the device body 1, a plurality of receiving rollers 7 are rotatably mounted on the side of the reeling roller 4, a label peeling mechanism 2 is provided between two receiving rollers 7, and a cutting mechanism 3 is provided on the top of the device body 1; the label peeling mechanism 2 comprises a limit block 21 installed on the top of the device body 1, a heating plate 22 is provided on the side of the limit block 21, and a peeling mechanism 2 is provided at one end of the limit block 21 Angle 23, a guide roller 24 is provided at the other end of the limit block 21, a tensioning roller 25 is provided on one side of the guide roller 24, and the tensioning roller 25 is adapted to the limit block 21, a roller wall 5 is provided on the side of the unwinding roller 4, a driving motor 6 is installed at the bottom of the unwinding roller 4, a winding roller 10 is installed on the top of the device body 1, and a driving motor 6 is installed at the bottom of the winding roller 10, label paper 8 is installed on the side of the unwinding roller 4 and multiple receiving rollers 7, and a label 9 is installed on the side of the label paper 8. When the label is automatically peeled off, take out a section without the winding roller The label paper 8 of 10 is pulled, the pressure block 13 on the side of the unwinding roller 4 is pulled, and the first spring 12 is driven to stretch, and a section of the label paper 8 is placed in the side pressure groove 11. When the pressure block 13 is released, the first spring 12 rebounds, and the side pressure groove 11 is driven to fix one end of the label paper 8, and then the label paper 8 is wound around the side of the unwinding roller 4 to one side of the receiving roller 7, and the label paper 8 is wound around the side of the tensioning roller 25 to the opening of the peeling angle 23 on the limit block 21, and then the label paper 8 is wound around the other side of the limit block 21 to the side of the guide roller 24, and then passes through the two receiving rollers. 7, and is wound onto the side of the winding roller 10. At this time, the driving motor 6 is started to drive the unwinding roller 4 and the winding roller 10 to rotate. The label paper 8 is driven by the winding roller 10 and is transmitted along the multiple receiving rollers 7. When the winding roller 10 on the label paper 8 is transmitted to the position of the heating plate 22, due to the heat of the heating plate 22, the glue on the label 9 loses a certain viscosity and is more likely to fall off. When it is transmitted to the peeling angle 23, one end of the label 9 is peeled off by the peeling angle 23, the peeled end of the label 9 is removed, and the label 9 is pasted.

[0023] The working principle is as follows: when it is necessary to automatically peel off the label, take out a section of label paper 8 without the winding roller 10, pull the pressure block 13 on the side of the unwinding roller 4, drive the first spring 12 to stretch, and place a section of the label paper 8 in the side pressure groove 11. When the pressure block 13 is released, the first spring 12 rebounds, driving the side pressure groove 11 to fix one end of the label paper 8, and then the label paper 8 is wound around the side of the unwinding roller 4 to one side of the receiving roller 7, and the label paper 8 is wound around the side of the tensioning roller 25 to the opening of the peeling angle 23 on the limit block 21, and then from the other side of the limit block 21 to the side of the guide roller 24, through one side of the two receiving rollers 7, through the gap between the movable block 31 and the fixed block 32, and wound to the side of the winding roller 10. At this time, the drive motor 6 is started to drive the unwinding roller 4 and the winding roller 10 to rotate, and the label paper 8 is wound around the winding roller 1 0 is driven by multiple receiving rollers 7. When the winding roller 10 on the label paper 8 is transmitted to the heating plate 22 position, the heat of the heating plate 22 causes the glue on the label 9 to lose a certain stickiness and is more likely to fall off. When it is transmitted to the peeling angle 23 position, one end of the label 9 is peeled by the peeling angle 23, and the peeled end of the label 9 is removed and the label 9 is pasted. There is no need to manually peel off the label 9 on the label paper 8, which improves the efficiency of peeling the label 9. After a certain period of transmission and winding, the slider 36 is driven to slide in the slide groove 35 by pushing the movable block 31, and the second spring 37 is compressed, driving the cutting knife 33 to insert into the cutting angle 34. The cutting knife 33 cuts one end of the label paper 8, and the label paper 8 without the label 9 is removed from the position of the winding roller 10 for recycling, which improves the applicability of the device.

[0024] Example 2: Figure 1 and 3 As shown, the cutting mechanism 3 includes a movable block 31 provided on the top of the device body 1, a fixed block 32 is provided at one end of the movable block 31, a cutting knife 33 is installed on the side of the movable block 31, a cutting corner 34 is provided at one end of the fixed block 32, the cutting knife 33 is adapted to the cutting corner 34, a slide groove 35 is provided in the device body 1, a slider 36 is slidably installed in the slide groove 35, a second spring 37 is provided in the slide groove 35, the slider 36 is driven to slide in the slide groove 35 by pushing the movable block 31, the second spring 37 is compressed, and the cutting knife 33 is driven to be inserted into the cutting corner 34, the cutting knife 33 cuts one end of the label paper 8, and removes the label paper 8 without the label 9 from the position of the winding roller 10 for recycling, thereby improving the applicability of the device, and the remaining features are the same as those of Example 1.
