Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum foil roll processing technical field especially is applicable to small space multi -point positioning device of aluminum foil roll dense arrangement. BACKGROUND

[0002] In the production and processing equipment of aluminum foil roll, the aluminum foil roll usually needs to maintain strict position and stability in multiple processing steps to ensure the quality and precision of production. In this application scenario, the aluminum foil roll needs to be arranged in high density in limited space and to realize accurate limiting and buffering during positioning to meet its high-frequency operation demand. Traditionally, in order to ensure the stable positioning of aluminum foil roll in small space, single positioning device or limiting mode of one side shaft is usually used. However, these modes often cannot fully meet the high-density aluminum foil roll arrangement demand, thus having certain deficiencies in precision, durability and stability.

[0003] Specifically, the existing technology mainly has the following problems:

[0004] 1. Unstable positioning: the existing device cannot provide sufficient multi-point positioning and limiting support in small space, especially when multiple aluminum foil rolls are arranged densely, the traditional limiting mode often leads to uneven force on the shaft, resulting in shaking or position deviation, affecting the processing precision.

[0005] 2. Lack of buffering effect: the commonly used limiting device is of rigid structure and cannot effectively buffer during pushing and returning, so the aluminum foil roll is easily impacted during repeated operation, accelerating the wear of device components and reducing the service life of the equipment.

[0006] 3. Inconvenient maintenance: due to limited space, the traditional positioning and limiting device is complex in arrangement and operation and is not easy to adjust or maintain, which further increases the maintenance cost and easily leads to positioning precision decline after long-term use.

[0007] To solve the above problems, the industry usually adopts the way of improving single-side limiting structure or increasing positioning supports to improve the positioning stability of the equipment. However, this scheme, although improving the positioning effect to some extent, still has the following deficiencies: first, the improvement of single-side limiting structure can only partially reduce the shaft deviation problem and cannot completely eliminate the stability deficiency caused by compact space; second, increasing positioning supports will further occupy space and increase the installation difficulty of the equipment, still cannot meet the positioning demand of high-density aluminum foil roll arrangement. Therefore, an innovative structure capable of realizing stable and effective multi-point positioning in small space and having buffering function is urgently needed to solve the problems of poor positioning stability, low impact resistance and complex maintenance in the existing technology.

[0008] Therefore, how to achieve stable, multi-point positioning of aluminum foil rollers in a small space, while also having a buffering function, has become the technical problem to be solved by this utility model. Utility Model Content

[0035] The second positioning pressure wheel 9 is rotatably sleeved on the second rotating support shaft 11, the two ends of the second rotating support shaft 11 are fixedly connected with the second cylinder rod 13 respectively, so that the second positioning pressure wheel 9 is positioned at the second avoiding gap 14 through the second rotating support shaft 11, and a part of the second positioning pressure wheel 9 protrudes out of the second avoiding gap 14; the shaft limiting gap is formed between the first cylinder rod 15 and the second cylinder rod 13, and the shaft limiting groove 16 is arranged on the aluminum foil roll positioning support 1 and located below the shaft limiting gap;

[0038] Embodiment 1:

[0039] The small-space multi-point positioning device is suitable for an aluminum foil roll 4 system arranged at high density. In such a system, due to the high-frequency operation of the aluminum foil roll 4 and the limited space, the traditional positioning method cannot effectively solve the stability problem of the aluminum foil roll 4, and the problems of unstable positioning, poor impact absorption and difficult maintenance often occur. Through a series of innovative structures, the embodiment realizes stable, multi-point positioning and effective buffering of the aluminum foil roll 4 in a densely arranged scene, and significantly improves the durability and operation precision of the overall system.

[0040] In this application scenario, the aluminum foil roll 4 system usually includes multiple aluminum foil rolls 4, and these roll shafts are densely arranged at a small interval on the positioning support. The small-space multi-point positioning device in the embodiment is composed of two cylinders, two positioning pressure wheels and a roll shaft limiting structure matched with one side of the aluminum foil roll 4, and through stable cooperative action, stable positioning and positioning of each aluminum foil roll 4 are realized.

[0041] In the specific operation, each cylinder is installed on the corresponding side of the positioning support, and the push rods of the first cylinder 6 and the second cylinder 7 are respectively connected with the positioning press wheels and can be telescopically matched. The positioning press wheels are stably positioned through the rotating support shafts sleeved on the push rods of the cylinders, and this design ensures that the positioning press wheels can be adjusted with the push rods when the push rods are telescopically matched, avoids the impact and wear problems caused by the direct rigid contact between the positioning press wheels and the roller shafts, thereby providing a buffering effect and prolonging the service life of the device. The pushing action of the cylinders cooperates with the avoiding notches on the roller shafts, so that part of the positioning press wheels protrudes from the ends of the push rods, thereby realizing the accurate positioning of the aluminum foil roller 4 in the limited space.

[0042] In order to ensure the stable positioning effect in different pushing states, the embodiment designs the "axle limiting gap" structure between the push rods of the cylinders. When the first cylinder 6 and the second cylinder 7 are simultaneously pushed, the axle limiting gap between the push rods is reduced, so that the "axle limiting groove 16" below it is also reduced in opening, thereby further locking the roller shaft and preventing it from shaking or shifting. When the roller shaft is affected by external force, the change of the axle limiting gap enables the device to be flexibly adjusted, thereby ensuring the safe positioning of the roller shaft and the stability of the positioning. When the first cylinder 6 and the second cylinder 7 are in the original state without being pushed, the axle limiting gap between the push rods is increased, and the groove opening is also correspondingly increased, so that the device can be smoothly adjusted, loosened or repositioned to facilitate equipment maintenance or roller shaft replacement. This structure enables the device to realize flexible and reliable positioning and limiting effect in a limited space, and is especially suitable for high-demand scenarios where aluminum foil rollers 4 are densely arranged.

[0043] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connecting", "fixing", "threading" and the like should be understood in a broad sense.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
