[0002] Paper corner protectors, also known as edge boards, are one of the most popular packaging products internationally. They are used to replace wooden packaging and other bulky packaging methods, and are characterized by low price, light weight, sturdiness, and compliance with environmental protection requirements. Paper corner protectors are made by laminating multiple layers of paper strips with glue into thick cardboard and then forming them by roll pressing. Therefore, it is necessary to ensure that the multiple layers of paper strips are kept taut to prevent tilting. In the production process, multiple rolls of paper strips are often used for feeding. When the roll of paper strip is used up, the machine often needs to be stopped to replace the roll of paper strip and to re-thread the paper strips. The downtime reduces work efficiency and increases processing costs. Utility Model Content

[0019] Please see Figure 1-5 This utility model provides a non-stop replacement device for a paper corner protector production line, including a base 1. A support plate 2 is fixedly connected to the top of the base 1. A main material rack 3 is embedded on one side of the front of the support plate 2, and a secondary material rack 4 is embedded on the other side of the front of the support plate 2. Several first rotating shafts 5 are rotatably installed in the middle of the main material rack 3, and a first roll paper belt 6 is installed in the middle of the first rotating shafts 5. A second rotating shaft 7 is rotatably installed in the middle of the secondary material rack 4, and a second roll paper belt 8 is installed in the middle of the second rotating shaft 7. Several fixed seats 11 corresponding to the first rotating shafts 5 are provided on the side of the support plate 2 near the main material rack 3. The front of the base 1 is near the secondary material rack. A hanging column 9 is fixedly connected to the middle of one side of the frame 4. A paper tape stapler 10 is hung in the middle of the hanging column 9. Several photoelectric sensors 14 for detecting the remaining amount of paper tape are provided on the surface of the main feeding frame 3 and the surface of the auxiliary feeding frame 4. Several fixing plates 15 are connected to one side of the main feeding frame 3 and the auxiliary feeding frame 4. A buzzer 16 is installed on one side of the fixing plate 15 and a warning light 17 is installed on the other side of the fixing plate 15. The fixing base 11 includes a top guide roller 19, a bottom guide roller 20 and a connecting column 18 connecting the top guide roller 19 and the bottom guide roller 20. Cleaning brushes 21 are provided at the bottom of the top guide roller 19 and the top of the bottom guide roller 20.
[0020] In this embodiment, during the feeding process, the paper tape passes between the top guide roller 19 and the bottom guide roller 20. The brushes on the top guide roller 19 and the bottom guide roller 20 can clean the surface of the paper tape, sweep away some dust and impurities that may exist on the surface, and improve the processing quality of the product.
[0021] In this embodiment, the first roll paper tape 6 on the main feeding rack 3 is pulled out to the production line as a material source, and one end of the paper tape passes through the inside of the fixed seat 11, that is, between the top guide roller 19 and the bottom guide roller 20. During the use, as the production process progresses, the paper tape on the first roll paper tape 6 becomes less and less, and then the paper tape on the second roll paper tape 8 is replaced for material supply.
[0022] See Figure 1-5 A reinforcing frame is fixedly connected to the bottom of the support plate 2. The reinforcing frame is connected to the top of the base 1. Universal wheels 12 are installed on the corners of the bottom of the base 1. The main material rack 3 and the auxiliary material rack 4 are at the same height. The photoelectric sensor 14 corresponds to the first roll paper tape 6 and the second roll paper tape 8. Limiting baffles 13 are fixedly connected to the side of the first rotating shaft 5 near the main material rack 3 and the side of the second rotating shaft 7 near the auxiliary material rack 4. An operation panel is provided at the bottom of the front of the support plate 2. The buzzer 16 and the warning light 17 are electrically connected to the operation panel through the photoelectric sensor 14.
[0023] In this embodiment, when the thickness of the first roll paper tape 6 is reduced to a certain extent, the photoelectric sensor 14 on the main feeding rack 3 will be triggered, causing the buzzer 16 and the warning light 17 to work. Each first roll paper tape 6 and each second roll paper tape 8 will be detected by a photoelectric sensor 14, and will also be detected by a set of buzzers 16 and warning lights 17. The buzzer 16 will sound to remind the staff that there is not enough material left.
[0024] See Figure 1-5 A gap is provided between the top guide roller 19 and the bottom guide roller 20 to facilitate the passage of the paper tape. The connecting column 18 on the back of the fixed seat 11 is connected to the surface of the base 1. The bottom of the back of the support plate 2 is connected to the second bracket 23, and the top of the back of the support plate 2 is connected to the first bracket 22. The top of the second bracket 23 and the top of the first bracket 22 are both equipped with a storage rack 24. Several spare roll paper tapes 25 are placed inside the storage rack 24.
[0025] In this embodiment, when the remaining amount of the first roll paper tape 6 on the base 1 is insufficient and about to run out, it is only necessary to pull out the end of the second roll paper tape 8 in the same row and overlap it on the paper tape at the end of the first roll paper tape 6. Then, the two are overlapped and stapled together by using the paper tape stapler 10 to complete the connection process between the end of the first roll paper tape 6 and the end of the second roll paper tape 8. In addition, the spare roll paper tape 25 is placed inside the storage rack 24 on the back of the support plate 2 for use as a spare material source for replacement.
[0026] In practical use, this utility model's paper corner protector production line non-stop replacement device moves the entire device to the feeding area of the paper corner protector production line. The first roll of paper tape 6 on the main feeding rack 3 is pulled onto the production line as a feeding source, and one end of the paper tape passes through the inside of the fixed base 11, between the top guide roller 19 and the bottom guide roller 20. During use, as production progresses, the amount of paper tape on the first roll of paper tape 6 decreases. When the thickness of the first roll of paper tape 6 reduces to a certain extent, the photoelectric sensor on the main feeding rack 3... Sensor 14 triggers and activates buzzer 16 and warning light 17. Each first roll paper tape 6 and each second roll paper tape 8 is detected by a photoelectric sensor 14, which also triggers an alarm from a set of buzzers 16 and warning lights 17. The buzzer 16 sounds to alert the operator that there is insufficient material remaining. By observing the warning light 17, the operator can identify the roll with insufficient material. The second roll paper tape 8 is installed on the second rotating shaft 7 of the auxiliary material rack 4, thereby controlling the remaining material of the first roll paper tape 6. When the material is about to run out, simply pull out the end of the second roll paper tape 8 and overlap it with the end of the first roll paper tape 6. Then, use a paper tape stapler 10 to overlap and staple them together, completing the connection between the end of the first roll paper tape 6 and the end of the second roll paper tape 8. Afterwards, as the production line progresses, the end of the first roll paper tape 6 and the end of the second roll paper tape 8 will be pulled into the production line together for further processing. The paper tape on the second roll paper tape 8 will be used subsequently, thus completing the material roll replacement. Similarly, a new roll paper tape will be reinstalled on the first rotating shaft 5 for the next material replacement. When the second roll paper tape 8 is about to run out, the corresponding photoelectric sensor 14 will detect it, and the corresponding buzzer 16 and warning light 17 will sound an alarm. Then, staple the end of the second roll paper tape 8 to the roll paper tape in the same row as the previous one to complete the material replacement again. The entire device facilitates the non-stop replacement of paper tape rolls in the paper corner protector production line, improving efficiency and reducing production costs.
