Description

Technical Field

[0001] This utility model relates to the field of film production equipment technology, and in particular to a biaxially oriented film production apparatus. Background Technology

[0002] In modern industrial production, biaxially oriented films, with their superior properties such as high strength, good transparency, and barrier properties, are widely used in packaging, electronics, optics, and other industries. This has driven the continuous development of biaxially oriented film production equipment towards higher efficiency, precision, and intelligence. With the increasing market demand for biaxially oriented films and the gradual improvement in product quality requirements, the optimization and innovation of production equipment have become key drivers for the industry's continued development.

[0003] Currently, the existing technologies commonly used in the production of biaxially oriented films are mainly built around a series of complex and mature mechanical structures and technical principles. For example, in the film stretching stage, high-precision roller sets are often used to stretch the film longitudinally and laterally. The stretching force and ratio are controlled by the rotation speed and direction of the rollers driven by motors to ensure that the film achieves the expected physical performance indicators. In terms of automated control of the production process, advanced sensors are used to monitor parameters such as film thickness and tension in real time, and automated control systems are used to dynamically adjust equipment operating parameters, thereby ensuring the stability of the production process and the consistency of product quality.

[0004] However, a significant problem exists in existing biaxially oriented film production equipment: the height of the control unit is relatively fixed. In actual production scenarios, operators vary in height, and a fixed-height control unit cannot meet the convenient operation needs of workers of different heights. This not only leads to discomfort or even fatigue for operators during operation, affecting work efficiency, but also causes misoperation due to inconvenience, thus posing a potential threat to the smooth progress of the production process and product quality. This greatly limits the applicability of the equipment in different operator environments. Therefore, a biaxially oriented film production equipment is proposed to solve the above problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a biaxially oriented film production device, including a biaxially oriented film stretching apparatus 1. The apparatus utilizes a high-precision roller assembly within the biaxially oriented film stretching apparatus 1 to achieve longitudinal and transverse stretching of the film. The stretching force and ratio are controlled by the rotational speed and direction of the rollers driven by a motor, ensuring that the film achieves the expected physical performance indicators. A fixed cylinder 2 is fixedly connected to the top of the biaxially oriented film stretching apparatus 1, serving as a support base for a control unit 3. Its robust structure ensures the stable installation of the control unit 3. The control unit 3 is mounted on the top of the fixed cylinder 2, serving as the control core of the equipment. A lifting assembly is located at the bottom of the control unit 3, enabling precise height adjustment of the control unit 3 through mechanical linkage. A noise reduction assembly is located at the bottom of the biaxially oriented film stretching apparatus 1, effectively absorbing vibration energy during equipment operation through an elastic buffer structure.

[0035] The lifting assembly includes a connecting column 6, which serves as a transmission component for height adjustment. Its rigid structure ensures stable support for the control unit 3. The top of the connecting column 6 is fixedly connected to the bottom of the control unit 3, enabling direct linkage between the control unit 3 and the lifting assembly. A fixed cylinder 7 is fixedly connected to the top of the first fixed cylinder 2, serving as a sliding track for the connecting column 6. Its internal special structure limits the movement range of the locking ball 8. The connecting column 6 is slidably connected to the inner walls of the second fixed cylinder 7 and the first fixed cylinder 2, ensuring the smoothness of the height adjustment process. A spring 10 is installed on the outer wall of the second fixed cylinder 7, serving as the core component of the reset mechanism. Its elastic properties enable automatic locking of the control unit 3. A connecting ring 9 is fixedly connected to one end of the spring 10, serving as a driving component for the locking ball 8. Its annular structure ensures the stability of multiple locking balls. The synchronous control of spring 10 is achieved by fixing a fixed ring 11 at one end. The fixed ring 11 serves as the fixed end of spring 10, and its stable installation ensures the accurate transmission of the reset force. The inner wall of the fixed ring 11 is fixedly connected to the outer wall of the fixed cylinder 7, forming a stable support structure. The fixed cylinder 7 has multiple holes inside, and the inner walls of these holes are large in the middle and small at both ends. This special structure ensures the free sliding of the locking ball 8 while preventing it from falling off. Each hole has a locking ball 8 on its inner wall. The locking ball 8 is a key component of the locking mechanism, and its spherical design enables flexible engagement with the connecting column 6. The inner wall of the connecting ring 9 is set on the outer wall of the multiple locking balls 8 to ensure the synchronous movement of the locking balls 8. The outer wall of the connecting ring 9 is fixedly connected to the connecting cylinder 12, which serves as a manual operating component. Its external design facilitates the application of force by the user.

[0036] Reference Figure 1 , Figure 4 and Figure 5The noise reduction component includes multiple springs 18 and 22. These springs serve as the main components of the vibration damping system, and their combined use achieves multi-directional vibration absorption. The multiple springs 18 and 22 are located at the bottom of the biaxial stretching film apparatus 1, forming a bottom vibration damping structure. A protective shell 4 is slidably connected to the outer wall of the biaxial stretching film apparatus 1. The protective shell 4 serves as the outer protective layer of the equipment and also provides a mounting reference for internal components. Multiple support feet 5, arranged in a rectangular array, are fixedly connected to the bottom of the protective shell 4. The support feet 5 serve as the contact parts between the equipment and the ground. Its distribution design ensures overall stability. The bottom of the biaxial stretching film apparatus 1 is fixedly connected to multiple fixed blocks 13 and connecting blocks 20. The fixed blocks 13 serve as the fixing points for the transmission mechanism; their robust structure ensures effective force transmission. Each fixed block 13 is rotatably connected to a transmission plate 14, which acts as a reverse motion mechanism. Its lever principle achieves reverse vibration cancellation. Each transmission plate 14 is rotatably connected to a connecting block 15, and each connecting block 15 has a T-shaped slider 16 fixedly connected to its bottom. The T-shaped slider 16 serves as a guide component, and its special structure… To ensure the linear motion of connecting block 15, multiple T-shaped sliders 16 are slidably connected inside the protective shell 4, forming a stable sliding pair. One end of each spring 18 is fixedly connected to a protective plate 17, which serves as the fixed end of spring 18. Its plate-like structure increases the contact area. The other end of each spring 18 is fixedly connected to a protective plate 19, which serves as the other fixed end of spring 18, ensuring a uniform distribution of elastic force. One side of each protective plate 17 is fixedly connected to the outer wall of connecting block 15, enabling direct transmission of vibration energy. Multiple springs 18 are fixedly connected to the outer wall of the protective shell 4 to form a stable installation structure. Each connecting block 20 is slidably connected to a fixed shell 21 on its outer wall. The fixed shell 21 serves as a guide component for the connecting block 20, and its internal space restricts the range of motion. The bottoms of multiple fixed shells 21 are fixedly connected to the bottom of the inner wall of the protective shell 4 to ensure the stability of the overall structure. One end of each spring 22 is fixedly connected to the bottom of the connecting block 20 to directly absorb vertical vibrations. The other end of each spring 22 is fixedly connected to the bottom of the inner wall of the fixed shell 21.

[0037] Working principle: During the height adjustment of the control mechanism 3, pulling down the connecting cylinder 12 causes the connecting cylinder 12 to move simultaneously, pushing the connecting ring 9 to move until it separates from the retaining ball 8 on one side. This provides space for the retaining ball 8 to move inside the fixed cylinder 7. Because the groove inside the fixed cylinder 7 has a structure that is larger in the middle and smaller at both ends, the retaining ball 8 can slide inside the fixed cylinder 7 without accidentally sliding out. As the connecting ring 9 moves, it pushes the spring 10 to compress, which in turn pushes the control mechanism 3 to move up and down. During this process, the outer wall of the connecting column 6 pushes the retaining ball 8 within the fixed cylinder. The internal sliding mechanism 7 allows the control unit 3 to move to a suitable height. Once the tension on the connecting cylinder 12 is released, the rebound force of the spring 10 pushes the connecting ring 9 to move again to the inner wall of the locking ball 8. This causes the locking ball 8 to engage with a specific groove inside the connecting column 6, thus fixing the height of the control unit 3 at the top of the connecting column 6. This achieves the effect of adjusting the position of the control unit 3 according to the different heights of the workers, solving the problem that the height of the control unit 3 in traditional equipment is relatively fixed and difficult to adjust according to the different heights of the workers, which can easily hinder the use of the equipment. This enhances the applicability of the equipment.

[0038] During the noise reduction process, the vibration generated by the biaxial stretching film apparatus 1 causes it to slide up and down on the inner wall of the protective shell 4, and causes the fixed block 13 and the connecting block 20 to move synchronously. While the fixed blocks 13 on both sides are moving, they will drive the connecting block 15 to move in the opposite direction through the transmission plate 14, and cause the T-shaped slider 16 to slide inside the protective shell 4, limiting the movement direction of the connecting block 15. The moving force of the connecting block 15 will drive the spring 2 18 to compress or stretch through the protective plate 17. While the connecting block 2 20 is moving, it will drive the spring 3 22 to compress or stretch. The compression or stretching of the spring 2 18 and the spring 3 22 will reduce the vibration generated by the biaxial stretching film apparatus 1, thus achieving the noise reduction effect of the equipment. This solves the problem that traditional equipment will generate a certain amplitude of vibration during operation, resulting in a large noise that affects the surrounding staff, and enhances the noise reduction effect of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
