Abstract
Description
Technical Field
[0001] This utility model relates to the field of bubble bag processing technology, and in particular to an automatic alignment and correction device for bubble bag processing. Background Technology
[0002] Bubble bags, also known as bubble wrap or bubble paper, are a common packaging material primarily used to protect fragile or shock-sensitive items during transportation. Typically, bubble bags are made by heat-sealing two layers of bubble film. Before heat sealing, the two layers need to be aligned and corrected to ensure the quality of the finished product. This alignment usually occurs during the conveying process of the bubble film, by repeatedly altering its trajectory. However, this method requires a considerable conveying distance for the bubble film to be aligned, and the limited space in actual processing areas makes it difficult to provide sufficient conveying distance for the bubble film to be aligned. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to solve the problem that the required moving distance for bubble wrap correction is too long, and the actual processing area is limited, making it impossible to meet the required conveying distance for bubble wrap correction.
[0004] To solve the problems of the prior art, the technical solution of this utility model is as follows: it includes a device frame, the device frame is provided with a tension structure, the end of the tension structure is rotatably connected to an abutment shaft, a limit plate frame is provided on the side near the abutment shaft, a steering shaft is provided on the side of the limit plate frame away from the abutment shaft, and a limiting shaft is provided on the side of the limit plate frame located between the steering shaft and the abutment shaft.
[0005] Furthermore, the tensioning structure includes a spring tensioning mechanism and a connecting seat disposed at the end of the spring structure. The tensioning structure is connected to the abutment shaft through the connecting seat, ensuring that the tensioning mechanism can drive the abutment shaft to move.
[0006] Furthermore, the tensioning structure is provided in two parts, which are arranged opposite to each other, and the spring structure inside the tensioning structure always remains in a contracted state, so that the tensioning structure can use the internal spring structure to keep the two abutting shafts away from each other.
[0007] Furthermore, the limiting plate frame is trumpet-shaped, with the side with a larger diameter facing the stretching structure and the side with a smaller diameter being semi-circular. The side with a larger diameter of the limiting plate frame also extends horizontally to both sides.
[0008] Furthermore, the opening end of the limiting plate frame is covered by a stretching structure, and the diameter of the opening end of the limiting plate frame is greater than the length of the abutment shaft, thereby increasing the diameter of the opening end of the limiting plate frame to ensure that the bubble film can enter smoothly.
[0009] Furthermore, the abutment shaft has an overall circular cylindrical structure with inclined stepped surfaces. The diameter of the stepped portion of the abutment shaft is adapted to the width of the bubble wrap material. The inclined portion of the abutment shaft can restrict the movement of the bubble wrap, thereby aligning the two bubble wraps.
[0010] Furthermore, there are two steering shafts with a gap between them. The width of the gap is adapted to the thickness of the double-layer bubble wrap material, ensuring that the bubble wrap can move through the gap between the two steering shafts.
[0011] Furthermore, the limiting plate frame has a through groove on the side near the limiting shaft. The limiting shaft is installed in the through groove by means of a washer and bolts. There are four limiting shafts in total. The four limiting shafts are respectively adapted to the abutment shaft and the steering shaft. The limiting shaft can change its position in the through groove by bolts to adapt to different usage conditions.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] This invention utilizes a tension structure within the equipment frame to move the abutment shafts away from each other. As the abutment shafts move away, they push the bubble wrap to generate tension. Under this tension, the bubble wrap slides along the inclined surface of the abutment shaft and moves to the center position of the abutment shaft. Subsequently, the bubble wrap moves to the steering shaft and bends through it. If the bubble wrap deviates during this process, it will come into contact with the limiting plate frame. The diameter of the limiting plate frame gradually decreases, pushing the bubble wrap back to its original position. This ensures that the bubble wraps are aligned with each other, and the aligned bubble wrap folds back along the direction of movement without needing to continue moving forward, thus reducing the space required for subsequent installation of auxiliary equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figure 1-4 As shown, an automatic alignment and correction device for bubble wrap processing includes a frame 1. A tensioning structure 2 is installed inside the frame 1. An abutment shaft 3 is rotatably connected to the end of the tensioning structure 2. The tensioning structure 2 includes a spring tensioning mechanism and a connecting seat at the end of the spring structure. The tensioning structure 2 is connected to the abutment shaft 3 via the connecting seat, ensuring that the tensioning mechanism 2 can drive the abutment shaft 3 to move. Two tensioning structures 2 are provided, arranged back-to-back. The spring structure inside the tensioning structure 2 is always in a contracted state, allowing the internal spring structure to keep the two abutment shafts 3 away from each other. The abutment shaft 3 is generally a circular cylindrical structure with an inclined stepped surface. The diameter of the stepped portion of the abutment shaft 3 is adapted to the width of the bubble wrap material. The inclined portion of the abutment shaft 3 can restrict the movement of the bubble wrap, thereby aligning the two bubble wraps.
[0021] A limiting plate frame 4 is provided on the side near the abutment shaft 3. The open end of the limiting plate frame 4 covers the stretching structure 2, and the diameter of the open end of the limiting plate frame 4 is larger than the length of the abutment shaft 3. Increasing the diameter of the open end of the limiting plate frame 4 ensures that the bubble wrap can enter smoothly. The limiting plate frame 4 is trumpet-shaped, with the side with the larger diameter facing the stretching structure 2, and the side with the smaller diameter being semi-circular. The side with the larger diameter of the limiting plate frame 4 also extends horizontally to both sides. A steering shaft 5 is provided on the side of the limiting plate frame 4 away from the abutment shaft 3. There are two steering shafts 5. A gap is left between the two steering shafts 5, and the width of the gap is adapted to the thickness of the double-layer bubble wrap material to ensure that the bubble wrap can move through the gap between the two steering shafts 5. A limiting shaft 6 is provided on the side of the limiting plate frame 4 between the steering shaft 5 and the abutment shaft 3. A through groove is opened on the side of the limiting plate frame 4 near the limiting shaft 6. The limiting shaft 6 is installed in the through groove by means of a washer and bolts. There are four limiting shafts 6 in total. The four limiting shafts 6 are adapted to the abutment shaft 3 and the steering shaft 5 respectively. The limiting shaft 6 can change its position in the through groove by bolts to adapt to different usage conditions.
[0022] Working principle description: This utility model provides tension to the bubble film during the conveying process through the tensioning structure 2. Under the action of tension, the bubble film moves to the center position along the inclined stepped surface of the abutment shaft 3, ensuring that the two vertical bubble films are aligned at this time. Then the bubble film continues to move into the limiting plate frame 4 and turns around the turning shaft 5. If the bubble film deviates again during the movement inside the limiting plate frame 4, it will contact the limiting plate frame 4. The diameter of the limiting plate frame 4 gradually decreases to fit the abutment shaft 3, limiting the deviation distance of the bubble film and forcing the bubble film to move along a fixed line until it leaves the limiting plate frame 4, passes through the tensioning structure 2, and turns back for storage or direct processing. During the process of entering and leaving the limiting plate frame 4, the bubble film will always be in contact with the limiting shaft 6. The limiting shaft 6 ensures that the bubble film moves in a horizontal state, avoiding horizontal tilting of the bubble film under the action of tension, which would affect the alignment effect.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
