Abstract
Description
Technical Field
[0001] This application relates to the field of lithium battery separator production technology, and in particular to a novel chain clamping device for a horizontal stretching machine. Background Technology
[0002] During the production of diaphragms, stretching is a crucial step to orient the molecular chains, thereby improving the product's performance. However, a common problem is that the diaphragm wrinkles as it enters the chain clamp, causing it to detach. This detachment necessitates stopping production and manually guiding the diaphragm back into the clamp, causing significant disruption to the process. Utility Model Content
[0003] To overcome the above-mentioned defects, this application provides a novel chain clamping device for a horizontal stretching machine, including a base and a clamping mechanism, wherein the clamping mechanism is disposed on the base; the clamping mechanism is used to close with the base to clamp the edge of the diaphragm; the clamping surface of the clamping mechanism is provided with a groove, the groove being used to hold the diaphragm.
[0004] Furthermore, the clamping mechanism includes a right-angle clamp for closing with the base to clamp the edge of the diaphragm.
[0005] Furthermore, the groove is formed on the clamping surface of the right-angle clamp.
[0006] Furthermore, the groove has a width of 10mm, a length of 100mm, and a depth of 5mm.
[0007] Furthermore, the clamping mechanism also includes a rotating component, which is connected to the right-angle clamp and the base respectively, and is used to control the opening and closing of the right-angle clamp.
[0008] Furthermore, the rotating assembly includes a rotating shaft and a vertical rod; the rotating shaft is connected to the right-angle clamp, and the vertical rod is connected to the base.
[0009] Furthermore, the rotating assembly also includes a right-angle connecting rod, which is connected to the rotating shaft and the upright respectively.
[0010] Furthermore, the rotating assembly also includes a connecting rod, which is connected to the rotating shaft.
[0011] The above-mentioned technical solution of this application has the following advantages: The novel chain clamp device for a horizontal stretching machine provided in this application features a clamping mechanism mounted on a base. This clamping mechanism is used to close with the base to clamp the edge of the diaphragm. The clamping surface of the clamping mechanism has a groove for holding the diaphragm in place. When the diaphragm is subjected to high temperatures inside the horizontal stretching machine, it may soften and gel. When the clamping surface of the chain clamp is concave, the edge of the clamped diaphragm tends to melt, becoming a thick edge that accumulates in the groove and is tightly held in place. This effectively avoids the problem of detachment, ensures that the diaphragm receives good stretching, increases the performance of the diaphragm, and avoids waste caused by detachment.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0018] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.
[0019] Currently, the chain clamps in diaphragm stretching devices experience detachment, leading to unstable chain clamp fixation during diaphragm stretching and affecting membrane performance. The purpose of this application is to improve the chain clamp fixation of the diaphragm during the stretching process, thereby increasing diaphragm performance and preventing waste caused by detachment.
[0020] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0021] like Figure 1 As shown in the figure, this application provides a novel chain clamping device for a horizontal stretching machine, including a base 1 and a clamping mechanism. The clamping mechanism is disposed on the base 1. The clamping mechanism is used to close with the base 1 to clamp the edge of the diaphragm. The clamping surface of the clamping mechanism is provided with a groove, which is used to hold the diaphragm.
[0022] In some embodiments, the clamping mechanism includes a right-angle clamp 2, which is used to close with the base 1 to clamp the edge of the diaphragm.
[0023] In some embodiments, the groove is formed on the clamping surface of the right-angle clamp 2.
[0024] In some embodiments, the groove has a width of 10 mm, a length of 100 mm, and a depth of 5 mm.
[0025] In some embodiments, the clamping mechanism further includes a rotating component, which is connected to the right-angle clamp 2 and the base 1 respectively, for controlling the opening and closing of the right-angle clamp 2.
[0026] In some embodiments, the rotating assembly includes a rotating shaft 3 and a vertical rod 4; the rotating shaft 3 is connected to the right-angle clamp 2, and the vertical rod 4 is connected to the base 1.
[0027] In some embodiments, the rotating assembly further includes a right-angle connecting rod 5, which is connected to the rotating shaft 3 and the upright 4 respectively.
[0028] In some embodiments, the rotating assembly further includes a connecting rod 6, which is connected to the rotating shaft 3.
[0029] The chain clamp device provided in this application embodiment adopts a hollow clamping surface. A groove with a width of 10mm, a length of 100mm, and a groove depth of 5mm is made on the clamping surface of the chain clamp. By modifying the plane of the chain clamp, the friction of the chain clamp film surface is increased.
[0030] Inside the horizontal stretching machine, the diaphragm is clamped tightly to the base by right-angle clamps. The chain clamps on both sides of the horizontal stretching machine then perform the stretching operation, stretching the diaphragm laterally. At this time, the chain clamps tighten, firmly fixing the diaphragm and preventing it from coming off during the stretching process.
[0031] Because the diaphragm is subjected to high temperatures within the horizontal stretching machine, it may soften and gel. Furthermore, the lateral stretching of the machine generates a force towards the stretching center, making it prone to slipping out of the clamp. When the clamping surface of the chain clamp is concave, the edge of the clamped diaphragm tends to melt, becoming a thick edge that accumulates in the groove and is tightly held in place, effectively preventing slippage. This ensures the diaphragm receives adequate stretching, increases its performance, and avoids waste caused by slippage.
[0032] Meanwhile, after the diaphragm exits the transverse stretching machine, because both sides have thick edges, it can effectively prevent the diaphragm from flipping over or wrinkling at the edges when entering the extraction and winding processes.
[0033] The novel chain clamp device for a horizontal stretching machine provided in this application embodiment features a clamping mechanism mounted on a base. This clamping mechanism is used to close with the base to clamp the edge of the diaphragm. The clamping surface of the clamping mechanism has a groove for holding the diaphragm in place. When the diaphragm is subjected to high temperatures inside the horizontal stretching machine, it may soften or gel. When the clamping surface of the chain clamp is concave, the edge of the clamped diaphragm tends to melt, becoming a thick edge that accumulates in the groove and is tightly held in place. This effectively avoids the problem of detachment, ensures that the diaphragm receives good stretching, increases the performance of the diaphragm, and avoids waste caused by detachment.
