Description

Technical Field

[0001] This invention relates to an apparatus and method for preparing high-performance environmentally friendly labels. Background Technology

[0002] In traditional label manufacturing processes, the liquid level in the coating machine drops after the adhesive is consumed, resulting in a reduction in the contact area of ​​the coating roller. This leads to unstable coating amount or even insufficient adhesive, affecting the label bonding quality. Furthermore, prolonged static placement causes functional fillers in the adhesive to settle, and temperature fluctuations affect the coating effect. There is also a lack of effective online stirring and constant temperature maintenance.

[0003] Therefore, a high-performance environmental label preparation device and preparation method are proposed to address the above issues. Summary of the Invention

[0004] The purpose of this invention is to overcome the existing defects by providing a high-performance environmentally friendly label preparation device and method, which can solve the problems mentioned in the background art of the decline of the adhesive liquid level and the sedimentation of fillers inside the traditional coating machine affecting the bonding effect of the coated label.

Simultaneously, the coordinated design of the stirring shaft and heat exchange pipes can precisely maintain the adhesive at the optimal coating temperature through the heat exchange pipes, while also preventing the sedimentation of functional fillers through stirring. This solves the problem of uneven composition of the adhesive after prolonged standing, ensuring the adhesion and antibacterial properties of the labels. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown: Equipment for preparing high-performance environmentally friendly labels: The machine body 1 consists of a face paper roller 3, a coating machine 2, a bottom paper roller 5, a pressing roller group 6, and a finished product winding roller 7, which are respectively arranged before and after the label production steps. The face paper of the face paper roller 3 is coated by the coating machine 2, and the adhesive inside the coating machine 2 is applied to the side of the face paper. The bottom paper roller 5 is located on the side of the coating machine 2 away from the face paper roller 3, and the bottom paper is located below the face paper after being unfolded. After being twisted and squeezed by the pressing roller group 6, the upper face paper and the lower bottom paper are bonded by the adhesive on the side of the face paper to form a label. Finally, the finished label is wound and wound on the finished product winding roller 7. At the same time, multiple guide rollers 4 are added inside the machine body 1 to guide the face paper or bottom paper.

[0020] A sinker 27 is installed inside the coating machine 2 to adjust the height of the adhesive inside the coating machine 2 in real time, ensuring that the adhesive inside maintains sufficient contact area with the coating roller 29 of the coating machine 2, thereby ensuring that the side of the paper after passing through the coating roller 29 is coated with sufficient adhesive. The sinker 27 can slide up and down along the guide rod 26 fixed inside the coating machine 2. A lifting motor 24 and a lead screw 25 fixedly connected to the output shaft of the lifting motor 24 are installed on the side of the coating machine 2. The lead screw 25 is rotatably installed on the side of the coating machine 2. The lead screw 25 and the sinker 27 can be threadedly connected. Therefore, after the lifting motor 24 is started and drives the lead screw 25 to rotate, the entire sinker 27 can be driven to slide up and down along the guide rod 26. As the entire sinker 27 gradually sinks, the internal cavity space of the coating machine 2 is reduced, thereby increasing the liquid level of the adhesive inside the coating machine 2.

[0021] The coating machine 2 also integrates a stirring shaft 22 for stirring and a heat exchange pipe 23 for maintaining the temperature of the adhesive inside the coating machine 2. A stirring motor 21 is also installed on the side of the coating machine 2, and the output shaft of the stirring motor 21 is fixedly connected to the stirring shaft 22. After the stirring motor 21 is started and the high-temperature liquid medium is introduced into the heat exchange pipe 23, the stirring shaft 22 rotates, and the heat exchange pipe 23 increases the temperature of the adhesive inside the coating machine 2. At the same time, it keeps the adhesive in a coatable state and improves the quality of subsequent coating.

[0022] A movable connecting rod 85 is installed between the control box 8 of the overall device and the valve handwheel 234 of the heat exchange pipe 23. A fixed seat 84 is fixed to the side of the control box 8. A stop bar 83 located on the side of the start button of the control box 8 can slide along the fixed seat 84. The two ends of the movable connecting rod 85 are rotatably connected to the stop bar 83 and the valve handwheel 234, respectively. Therefore, after turning the valve handwheel 234 to open the valve of the heat exchange pipe 23, the movable connecting rod 85 simultaneously pulls the stop bar 83 to slide outward from the control box 8. At this time, the notch of the stop bar 83 corresponds to the button of the control box 8, and the overall device can be started for label production using the start button of the control box 8. Therefore, the overall device can only be started after the heat exchange medium is connected inside the heat exchange pipe 23. This ensures the rationality of the entire device operation process.

[0023] Example 1: The conical blocks 271 of the sinker 27 are fixedly connected by a connecting plate 272. The connecting plate 272 has through holes that slide with the guide rod 26. An L-shaped connecting rod 273 is fixed on the side of the connecting plate 272. The L-shaped connecting rods 273 are fixedly connected by a U-shaped connecting rod 274. A threaded boss 275 that is threaded to the lead screw 25 is fixed on the side of the U-shaped connecting rod 274. Therefore, the connection between the sinker 27 and the lead screw 25 is located on the outside of the coating machine 2 to avoid the adhesive inside the coating machine 2 from affecting the effect of the thread transmission.

[0024] Example 2: The heat exchange pipe 23 can be divided into two built-in pipes 231 inside the coating machine 2 and a circulation pipe 232 connecting the two built-in pipes 231. An interface pipe 233 is fixed at the other end of the built-in pipes 231. Therefore, there is enough space between the two built-in pipes 231 to facilitate the placement of the stirring shaft 22 inside the coating machine 2, ensuring the rationality of the overall structure of the coating machine 2.

[0025] Example 3: Mounting plate 81 and heat insulation plate 82 are respectively installed on the side of control box 8 and coating machine 2. Heat insulation plate 82 is fixedly connected to coating machine 2, while mounting plate 81 is fixed on the side of heat insulation plate 82 adjacent to control box 8. Heat insulation plate 82 not only provides heat insulation, but also increases the gap between control box 8 and coating machine 2, allowing space for air circulation and preventing the heat of coating machine 2 from affecting the normal operation of control box 8.

[0026] Example 4: A protective plate 28 is fixedly installed on the top of the coating machine 2. The protective plate 28 is located between the sinker 27 and the face paper to prevent the sinker 27 from sliding too far upward and to prevent interference with the normal production of the face paper.

[0027] Methods for preparing high-performance environmentally friendly labels: S1. The heat exchange pipe 23 is opened by rotating the valve body handwheel 234 to connect the heat exchange medium. At the same time, the movable connecting rod 85 drives the baffle 83 to slide, so that the notch on the baffle 83 is aligned with the start button of the control box 8. S2. Operate the start button to start the whole machine. The lifting motor 24 drives the lead screw 25 to rotate, which drives the sinker 27 to descend along the guide rod 26 to the preset position. Adjust the liquid level of the adhesive inside the coating machine 2 so that the adhesive contacts the coating roller 29. S3. Start the stirring motor 21, drive the stirring shaft 22 to rotate, and maintain the temperature of the adhesive through the heat exchange pipe 23, so that the adhesive is uniformly dispersed and has a stable viscosity. S4. The face paper roll 3 feeds the face paper, which is guided into the coating machine 2 by the guide roller 4. The coating roller 29 applies the adhesive to the side of the face paper. S5. The bottom paper roll 5 unwinds the bottom paper, which is guided by the guide roller 4 to the bottom of the face paper. It then enters the pressing roller group 6 together with the glued face paper to be laminated and formed into a label tape. S6. The composite label tape is guided by guide roller 4 and then wound up by finished product take-up roller 7.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
