Technical Field

[0001] The utility model mainly relates to the technical field of honeycomb paperboard processing equipment, in particular to an edge binding device for paperboard processing. Background Art

[0002] Cardboard, also known as board paper, is mainly corrugated cardboard or honeycomb cardboard. It is a thick paper sheet made of various pulps and fibers interwoven with each other. Its main raw material is recycled cardboard, and the thickness can be high or low. It is mainly used in packaging boxes, packaging or cushioning of large equipment, but the stiffness and burst resistance of this cardboard are relatively low.

[0003] Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of sandwich structure environmentally friendly and energy-saving material made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral force-bearing member - paper core, and gluing surface paper on both sides. The processing process of honeycomb paperboard mainly includes five units, namely, paper loading unit, honeycomb paper core stretching and shaping unit, honeycomb paper core gluing unit, honeycomb paperboard composite unit and honeycomb paperboard cutting unit. Since the side of honeycomb paperboard is easy to wrinkle and damage, some customers have higher requirements on the strength of paper boxes formed by paperboard. Therefore, after cutting, it can be decided whether to wrap the side of the paperboard according to the actual situation. At present, the wrapping operation is mostly manual operation, mainly to stick transparent tape on both sides of the paperboard to prevent wrinkling and damage in later use and increase the service life of the paper box. However, paperboards are produced in batches in rolls. If wrapping is required, the labor intensity is large for the staff, and the efficiency is low. It is also easy to stick the transparent tape crooked, affecting the appearance. Utility Model Content

The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] Please refer to the attached Figure 1-3A cardboard processing hemming device comprises a support platform 1, on which two automatic hemming mechanisms 2 are arranged, and the two automatic hemming mechanisms 2 are symmetrically distributed, a honeycomb panel body 3 is arranged between the two automatic hemming mechanisms 2, each of the automatic hemming mechanisms 2 comprises a moving seat 21, on the upper surface of the moving seat 21 a first tray 22 and a second tray 23 for placing transparent tape are arranged, a first guide roller 24 and a second guide roller 25 are arranged at the corner positions of the upper surface of the moving seat 21, and a hemming assembly 26 is arranged on the side close to the second guide roller 25.

[0024] The above structure uses the automatic edge wrapping mechanism 2 to achieve that after the paperboard is cut, both sides of the honeycomb paperboard can be edge wrapped with transparent tape at the same time, without manual operation, saving time and labor, reducing labor costs and error rates, and improving the efficiency of the edge wrapping operation. It can also be used for paperboards with different cross-sectional sizes, and has certain universal applicability and practical value.

[0025] The specific operation is as follows: first, hold the turning handle 29 to drive the threaded column 281 to rotate. Under the constraints of the limiting groove 211 and the limiting protrusion 11, the moving seat 21 moves linearly. According to the size of the cross-section of the honeycomb panel body 3 that needs to be wrapped, a suitable distance between the two moving seats 21 is selected, and then two transparent films are respectively put on the first tray 22 and the second tray 23. Then, the transparent tape on the first tray 22 is passed around the first guide roller 24, the second guide roller 25, the first edge finishing roller 261, the second edge finishing roller 262, the third edge finishing roller 263 and the fourth edge finishing roller 264 in turn, and then the initial end of the transparent tape is adhered to the side of the honeycomb panel body 3, and then it is turned again. The handle 29 is turned so that the first edge-closing roller 261, the second edge-closing roller 262, the third edge-closing roller 263 and the fourth edge-closing roller 264 can press the transparent tape tightly against the two side edges of the honeycomb panel body 3. Then, as the honeycomb panel body 3 is driven, the transparent tape will be continuously pulled to stick to the two side edges of the honeycomb panel body 3 to complete the edge wrapping of the cardboard. If the transparent tape on the first tray 22 is used up, the transparent tape on the second tray 23 will be passed around the third guide roller 27, the first guide roller 24, the second guide roller 25, the first edge-closing roller 261, the second edge-closing roller 262, the third edge-closing roller 263 and the fourth edge-closing roller 264 in turn to complete the subsequent edge wrapping work.

[0026] Please refer to the attached Figure 2 and attached Figure 3The edge trimming assembly 26 includes a first edge trimming roller 261, a second edge trimming roller 262, a third edge trimming roller 263 and a fourth edge trimming roller 264, and the heights of the middle cylindrical parts of the first edge trimming roller 261, the second edge trimming roller 262, the third edge trimming roller 263 and the fourth edge trimming roller 264 gradually decrease. The central axes of the first edge trimming roller 261, the second edge trimming roller 262, the third edge trimming roller 263, the fourth edge trimming roller 264 and the second guide roller 25 are in the same plane. The height of the middle cylindrical part of the roller 262, the third edge-closing roller 263 and the fourth edge-closing roller 264 is gradually reduced, so that the transparent tape is gradually squeezed to achieve the goal of gradually sticking the transparent tape to the upper and lower positions of the side edge of the cardboard. A third guide roller 27 is arranged on the side close to the second tray 23. Through the mutual cooperation between the second tray 23 and the third guide roller 27, a placement position for spare transparent tape is provided, so that after the transparent tape on the first tray 22 is used up, the transparent tape on the second tray 23 can be quickly connected without interrupting the feeding of the cardboard, which is very convenient. Limiting grooves 211 are arranged on both sides of the bottom of the movable seat 21, and each of the limiting grooves 211 is slidably connected to the limiting protrusion 11, and the limiting protrusion 11 is arranged on the bracket 1. Through the mutual cooperation between the limiting protrusion 11 and the limiting groove 211, the movable seat 21 is constrained, so that the movable seat 21 can stably move linearly on the bracket 1, and support plates are arranged on both sides of the bracket 1 28. A threaded column 281 is provided on each of the two support plates 28. Each of the threaded columns 281 is threadedly connected to the corresponding movable seat 21, and the ends of the two threaded columns 281 are rotatably connected to a connecting plate 12. The connecting plate 12 is mounted in the middle position of the bracket 1. Through the connecting plate 12, a fulcrum is provided for one end of the threaded column 281. A turning handle 29 is provided at one end of each threaded column 281 away from the connecting plate 12 to provide a force point for the staff to facilitate the rotation of the threaded column 281.
