Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.

Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0028] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on another element or there can be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to one element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration, and do not represent the only embodiment.

[0029] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0030] Embodiment 1: in combination Figures 1-4 The present embodiment discloses a processing clamp for assembling a hollow fiber membrane assembly, aiming to improve clamping precision and stability by improving clamping structure and adding positioning mechanism, to ensure accurate alignment and stable clamping of the hollow fiber membrane bundle during assembly process, thereby improving the smooth progress of subsequent processing steps and the quality of the final product.

[0031] The processing clamp comprises two oppositely arranged first clamping blocks 100 and second clamping blocks 200, and the outer profile of the first clamping block 100 and the second clamping block 200 is a cuboid block structure, defining the length direction of the first clamping block 100 and the second clamping block 200 as the left-right direction and the width direction as the front-rear direction. Figure 1 The first clamping block 100 is located on the front side of the second clamping block 200.

[0032] The first clamp block 100 and the second clamp block 200 are respectively provided with a mounting groove 300 of a transverse slot structure on the adjacent side walls. Figure 2 As shown, Figure 2 The mounting groove 300 is provided on the front side wall of the second clamp block 200, and is parallel to the left-right direction along the length direction of the mounting groove 300. Four extension grooves 400 are arranged in the left-right direction, and the extension grooves 400 are longitudinal arc-shaped slots. The extension grooves 400 penetrate the second clamp block 200 from top to bottom, forming a two-way limiting assembly slot structure.

[0033] Further, two parallel guide rods 500 are arranged on the front side wall of the second clamp block 700 at the left and right sides. The axial direction of the guide rod 500 is parallel to the front-rear direction. The outer contour of the guide rod 500 is a circular rod structure, and the front end of the guide rod 500 is provided with a threaded hole 600. The axial direction of the guide rod 500 is parallel to the clamping splicing direction of the first clamp block 100 and the second clamp block 200, and the guide rod 500 and the second clamp block 200 are an integral structure.

[0034] It should be noted that the structure of the first clamp block 100 is basically the same as that of the second clamp block 200, and the difference is that the first clamp block 100 is not provided with a guide rod 500, but is provided with a guide hole 120 matched with the guide rod 500. As shown, Figure 4 The outer side of the guide hole 120 is provided with an opening 110, and the opening 110 is used for bolt penetration, so that the bolt can be connected with the threaded hole 600. The bolt connection can keep the clamping action of the first clamp block 700 and the second clamp block 700 fixed.

[0035] The mounting groove 300 is movably provided with a clamp block 700, and the clamp block 700 is movably arranged in the mounting groove 300. Figure 3As shown, the main body of the pressing block 700 is a strip-shaped plate structure, which can be inserted into the mounting groove 300, and the front side of the pressing block 700 is provided with an extension plate 710 corresponding to the extension groove 400. After assembly, the extension plate 710 is abutted in the extension groove 400 close to the side of the main body of the pressing block 700, which can ensure that the clamping film has a stable external limiting structure, and the movable connection between the pressing block 700 and the mounting groove 300 enables the pressing block 700 to slide in the mounting groove 300 in a certain direction during the clamping process. Therefore, the stable and sliding connection between the pressing block 700 and the mounting groove 300 enables the pressing block 700 to not cause rigid extrusion to the film when it first abuts against the film during the clamping process, thereby avoiding the film surface structure from being excessively rigidly pressed and reducing the film from being excessively shaken and misaligned due to rigid contact at the initial stage. This is beneficial to reducing the probability of damage to the film structure and improving the clamping stability and reliability. It should be noted that the clamping process needs to be manually operated, so the pressing block 700 will not easily fall out of the mounting groove 300. In other embodiments, an anti-falling structure can be further provided between the pressing block 700 and the mounting groove 300.

[0036] In combination Figure 1 and Figure 4 The pressing plates on the first clamping block 100 and the second clamping block 200 are spliced to form a plurality of clamping cavities a adapted to the outer contour of the hollow fiber bundle, which are used to accommodate and clamp the bottom end of the hollow fiber membrane bundle.

[0037] Further, the first clamping block 100 and the second clamping block 200 are provided with a plug-in groove 800 at the top, and the plug-in grooves 800 on the first clamping block 100 and the second clamping block 200 form a closed loop slot hole contour after splicing, which is used for the assembly of the wall plate of the subsequent casting cavity.

[0038] Embodiment 2: Based on embodiment 1, in combination Figure 5 As shown, in the embodiment itself, in order to further reduce the rigid damage during clamping, the pressing block 700 is provided with an elastic structure on the inner side of the mounting groove 300. The elastic structure includes a plurality of springs 730 uniformly distributed along the length direction of the mounting groove 300, and the extension direction of the spring 730 is parallel to the front and back directions.

[0039] Further, the second clamping block 200 is provided with a first positioning hole 210 on the inner side wall of the mounting groove 300, and the pressing block 700 is provided with a second positioning hole 720 corresponding to the first positioning hole 210 close to the side of the mounting groove 300. After the pressing block 700 is inserted into the mounting groove 300, the first positioning hole 210 and the second positioning hole 720 form a limiting slot hole structure of the spring 730.

[0040] In order to make the film material be more effectively and stably clamped during the clamping process, and avoid the film material from sliding accidentally during the clamping process to cause clamping misalignment, the protrusions 740 in the form of dot-shaped flanges are arranged on one side of the clamping gap of the pressing block 700.

[0041] In other embodiments, a lower limiting baffle is arranged at the top of the clamping cavity a to further improve the clamping limiting accuracy of the film material.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
