Description

Technical Field

[0001] This utility model relates to the technical field of waste film mechanisms, and in particular to a quick-disassembly waste film mechanism. Background Technology

[0002] With the rapid development of the packaging industry, box packaging machines are increasingly widely used in food, pharmaceutical, and daily chemical products. The waste film recycling device, as a key component, directly affects the equipment's operating efficiency and production costs. The main function of the waste film recycling device is to pull the used packaging film roll to a designated location and disassemble and replace it after the roll is exhausted. Traditional waste film recycling technologies mostly adopt mechanical film winding structures or fixed roller designs, using motor drives to achieve film winding and recycling. In recent years, with the advancement of automation technology, some devices have introduced intelligent control systems to improve winding accuracy and stability, such as monitoring film tension through sensors or using servo motors for precise driving. However, these technologies still face significant challenges in terms of structural complexity and manufacturing costs, especially in small and medium-sized enterprises, where expensive equipment investment and maintenance costs limit their widespread application. Furthermore, existing technologies in the waste film disassembly stage are mostly based on fixed connections or mechanical locking, which are complex to operate and inefficient, making it difficult to meet the demands of modern packaging production lines for rapid film replacement.

[0003] While existing waste membrane recycling devices can functionally meet basic winding and recycling requirements, they have significant shortcomings in disassembly efficiency, structural simplicity, and cost control. Traditional devices, when disassembling waste membranes, are often limited by the membrane material's retraction force, requiring significant manual force or specialized tools. This not only increases the labor intensity of operators but also risks equipment damage or waste membrane residue due to improper operation. Furthermore, existing devices often employ complex mechanical structures or multi-component designs, increasing manufacturing and assembly difficulties and resulting in high production costs. Given the high retraction force of waste membranes, existing technologies lack effective mechanisms to address this issue, making the disassembly process time-consuming and inefficient, and ill-suited to the demands of high-frequency, fast-paced modern production.

[0024] Please refer to Figures 1 to 6As shown, the present invention provides a quick-release waste film mechanism, including a rotating rod 11, a connecting rod 12, and an end block 13. Two end blocks 13 are arranged in opposite positions, and two connecting rods 12 are detachably installed between the end blocks 13. The rotating rod 11 is located between the two connecting rods 12 and is detachably installed on the end block 13. The rotating rod 11, located between the two connecting rods 12 and fixed to the end block 13 by its detachable installation, is responsible for rotating and winding the waste film. The connecting rods 12 provide structural support through their detachable connection with the end block 13, ensuring the overall stability of the mechanism. The end block 13, as a fixed base, is designed with a special connection structure (such as mounting holes 16 and locking holes 14 with locking screws) to facilitate the quick installation and disassembly of the rotating rod 11 and the connecting rod 12. Once the waste film is wound, simply loosen the locking mechanism and quickly remove the rotating rod 11 and connecting rod 12 to easily remove the wound waste film from the mechanism. Then, reinstall the new rotating rod 11 and connecting rod 12 for continued use. This design significantly simplifies the disassembly and replacement process of the waste film, improves operational efficiency, and reduces maintenance time.

[0025] One end of the rotating rod 11 extends through the end block 13, and the extended end of the rotating rod 11 is rotatably connected to the mounting plate 15. The rotatable connection may be through a bearing connection, which is prior art and will not be described in detail here.

[0026] The end of the rotating rod 11 away from the mounting plate is tapered, and a locking hole 14 is provided at its end. Both connecting rods 12 are tapered at their ends. The end of the upper connecting rod 12 away from the mounting plate 15 is tapered, and the end of the lower connecting rod 12 near the mounting plate 15 is tapered. The two end blocks 13 are provided with corresponding tapered holes 18, and the middle position of the end block away from the mounting plate 15 is provided with a tapered hole 18. The tapered hole 18 can be inserted into the tapered end of the rotating rod 11. The other side of the end block 13 is provided with a mounting hole 16, which is connected to the tapered hole 18. The mounting hole 16 corresponds to the locking hole 14 through a locking screw 17. The device is locked by the locking screw 17. The rotating rod 11 drives the device to rotate, causing waste film to wrap around it. To remove the waste film, the locking screw 17 must be removed. The tapered end of the lower connecting rod 12 disengages from the tapered hole 18 in the end block near the mounting plate 15. Simultaneously, the end block 13 away from the mounting plate 15 separates from the rotating rod 11 and the upper connecting rod 12, respectively. Figure 2 As shown. This mechanism utilizes the combination of three tapered holes and a shaft, making it easier to disassemble when the membrane's retraction force is high. Its advantages are simple structure, ease of manufacture, and low cost.

[0027] The working principle of this utility model:

[0028] This mechanism achieves the winding and quick unwinding of waste film through a combination of a rotating rod 11, a connecting rod 12, and end blocks 13. Two end blocks 13 are positioned opposite each other, serving as a fixed base, and are designed with tapered holes 18 and mounting holes 16 to facilitate the detachable installation of the connecting rod 12 and the rotating rod 11. The rotating rod 11 is located between the two connecting rods 12, with one end rotatably connected to the mounting plate 15 via a bearing, and the other end tapered and equipped with a locking hole 14, which engages with the tapered hole 18 and locking screw 17 of the end block for fixation. The ends of the two connecting rods 12 are also tapered, respectively matching the tapered holes of the end blocks 13, providing structural support and ensuring overall stability. During operation, the rotating rod 11 rotates, causing the waste film to wind onto it, while the connecting rods 12 and end blocks 13 work together to maintain the stability of the mechanism. After the waste film is wound, the locking screw 17 is loosened, and the tapered ends of the rotating rod 11 and the connecting rod 12 can quickly disengage from the tapered hole 18 of the end block 13, facilitating the removal of the wound waste film. Subsequently, the new rotating rod 11 and connecting rod 12 can be reinstalled for continued use. This mechanism utilizes the matching design of the tapered hole 18 and the tapered end to effectively cope with situations where the waste film has a large retraction force, simplifying the disassembly process. It has a simple structure, low manufacturing cost, significantly improves the efficiency of waste film replacement, reduces maintenance time, and is suitable for scenarios that require frequent waste film replacement.

[0029] The embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
