Description

Technical Field

[0001] This utility model relates to the field of multi-layer bubble wrap technology, and in particular to a multi-layer bubble wrap trimming machine. Background Technology

[0002] Multilayer bubble wrap, especially double-layer bubble wrap, has wide applications in packaging, logistics, and transportation. As the name suggests, multilayer bubble wrap is composed of multiple layers of materials. Double-layer bubble wrap is the most common type, consisting of one or more air bubbles sandwiched between two layers of plastic film. These air bubbles are usually formed between the films using a special process, providing excellent cushioning and shock absorption. One step in processing multilayer bubble wrap is cutting it, which requires a multilayer bubble wrap edge trimming machine.

[0003] The patent specification with publication number CN209699252U discloses an adjustable-gap bubble wrap trimming machine, including a fixed table and a leveling mechanism and a trimming mechanism disposed on both sides of the top of the fixed table. The leveling mechanism includes two leveling support plates, and a pressure roller, a second leveling roller, and a first leveling roller are arranged sequentially from left to right between the two leveling support plates. The trimming mechanism includes two trimming support plates, and a first rotating roller, a cutting roller, and a second transmission roller are arranged sequentially from left to right between the two trimming support plates. This invention uses a knob to rotate a double-threaded rod. The threads on the double-threaded rod drive two threaded sleeves to slide in opposite directions within a rotating groove. The threaded sleeves, through a connecting block, drive the sliding sleeves to move left and right on the surface of the mounting roller, thereby adjusting the gap between the two trimming blades. This achieves the effect of adjusting the trimming gap, facilitating use and reducing production costs.

[0004] In the above-mentioned technology, the threaded rod drives two threaded sleeves to slide in opposite directions or back to back within the rotating groove through the thread on its surface. The threaded sleeves drive the sliding sleeves to move left and right on the surface of the mounting roller through the connecting block, thereby adjusting the distance between the two trimming blades and achieving the effect of adjusting the cutting distance. However, when trimming multi-layer bubble wrap, due to production conditions, the cutting distances on both sides of the multi-layer bubble wrap are not consistent. The above-mentioned adjustment structure always adjusts the distance on both sides to be consistent each time the distance is adjusted, which leads to the situation of cutting more on one side during trimming. Therefore, a multi-layer bubble wrap trimming machine is needed to solve the above problem. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer bubble wrap trimming machine to solve the problem that existing multi-layer bubble wrap trimming machines are inconvenient to adjust the position of the cutter according to the trimming requirements.

[0008] The above structure allows for precise adjustment of the cutter's position during use, resulting in better edge cutting performance.

[0009] Preferably, the side view cross-sectional area of ​​the groove is larger than the side view cross-sectional area of ​​the slider, and the groove and the slider form a sliding connection.

[0010] Preferably, the nut is sleeved on the outside of the fixing bolt, and the nut and the fixing bolt form a threaded connection.

[0011] With the above structure, the threaded connection is more convenient to fix during use.

[0012] Preferably, the tensioning structure includes a mounting frame, a connecting frame, a rotating groove, a tensioning roller, and a rotating rod. The mounting frame is installed on the top of the front end of the workbench. The mounting frame has a rotating groove inside, and a rotating rod is installed inside the rotating groove. The connecting frame is installed at the bottom end of the rotating rod, and a tensioning roller is installed at the bottom end of the connecting frame.

[0013] Preferably, both ends of the tension roller are inserted into the interior of the connecting frame, and the tension roller is movably connected inside the connecting frame.

[0014] Preferably, the rotating rod is inserted into the interior of the rotating groove, and the rotating rod and the rotating groove form a threaded connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are: when using this multi-layer bubble wrap trimming machine, the position of the cutter can be precisely adjusted by adjusting the structure, and the multi-layer bubble wrap can be tensioned by the tensioning structure, so that the multi-layer bubble wrap has a better trimming effect.

[0016] 1. With an adjustable structure, when trimming the edges of multi-layer bubble wrap, the slider slides inside the groove, thereby precisely adjusting the position of the cutter. This allows the cutter position to be adjusted according to the trimming requirements, making trimming more convenient.

[0017] 2. By setting up a tensioning structure, when cutting the edges of multi-layer bubble film, the cooperation between the rotating rod and the rotating groove can push the tensioning roller to move downward, thus tensioning the multi-layer bubble film. This prevents the multi-layer bubble film from becoming loose during edge cutting, which would affect the cutting effect, thereby completing the tensioning work. Attached Figure Description
