[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] The core of the present utility model is to provide a packaging structure for a hollow fiber filter, which can realize the packaging of filters with different end sizes and different lengths, so that this packaging structure can be applied to filters of different specifications, improve the applicability of the packaging structure, save processing costs, time costs, and raw material costs, avoid the sluggish waste of the packaging structure, and save management costs and warehousing costs. Another core of the present utility model is to provide a packaging assembly including the packaging structure of the hollow fiber filter.

[0043] The packaging structure provided by the present utility model is used for the packaging of hollow fiber filters of different size specifications, and specifically includes an inner lining main body 1, an inner core group, and an adjusting pad 3. Please refer to Figure 1 、 Figure 7 .

[0044] Taking the relatively common hollow fiber filter as an example, such as Figure 2 , a packaging bag 4 as a sterile barrier is heat - molded on the outer side of the hollow fiber filter 5. The state in this figure shows the positional relationship of the packaging bag 4. Actually, after heat - molding processing, the packaging bag 4 is in a state of completely fitting around the outer periphery of the hollow fiber filter 5.

[0045] The hollow fiber filter 5 comprises a fiber membrane bundle 54, a housing 53, end heads 52, and liquid inlet / outlet ports 51. When packaging the hollow fiber filter 5, it is mainly necessary to limit and package the ends formed by the end heads 52 and the liquid inlet / outlet ports 51 at both ends of the hollow fiber filter 5 through a packaging structure.

[0046] Among them, the inner lining main body 1 is provided with a notch structure 10, which can be used for the limit installation of the ends of the hollow fiber filter 5. The form of the notch structure 10 can be set in combination with the shape of the ends of the hollow fiber filter 5 to fix the hollow fiber filter 5 to prevent rotation and movement, playing a buffering and protective role.

[0047] For the hollow fiber filter 5 with larger end dimensions, the support for the hollow fiber filter 5 can be formed through the notch structures 10 of the two inner lining main bodies 1, and there is no need to set up an inner core group.

[0048] If it is for the hollow fiber filter 5 with smaller end dimensions, the support for the hollow fiber filter 5 needs to be formed through the cooperation of the inner lining main body 1 and the inner core group. The width of the inner cavity 21 of the inner core group is adjustable. For example, for the hollow fiber filter 5 with slightly smaller end dimensions and the hollow fiber filter 5 with very small end dimensions, the width of the inner cavity 21 can be adjusted to be applicable to hollow fiber filters 5 of different dimensions.

[0049] Taking a specific embodiment as an example, the inner cavity 21 of the inner core group communicates with the notch structure 10 to form an installation cavity. This installation cavity is smaller in size relative to the notch structure 10, so it can be applicable to the hollow fiber filter 5 with slightly smaller end dimensions.

[0050] Taking another specific embodiment as an example, the inner core group adjusts the width of its inner cavity 21 to be very small, and the inner cavity 21 communicates with the notch structure 10 to form an installation cavity to further reduce the size of the installation cavity, which is applicable to the hollow fiber filter 5 with very small end dimensions.

[0051] If the hollow fiber filter 5 is cylindrical as Figure 2 , then each thickness specification of the hollow fiber filter 5 corresponds to an end dimension specification in one of the above specific embodiments, that is, if the thickness of the hollow fiber filter 5 is known, the corresponding end dimension is already determined. For hollow fiber filters 5 of different thickness specifications, when installing the inner core 2 and the notch structure 10, the part of the inner core 2 that fits the notch structure 10 reduces the installation interval of the end head 52, while the other part of the notch structure 10 provides a limit installation space for the liquid inlet / outlet ports 51. When packaging hollow fiber filters 5 of different thickness specifications, only the width of the inner cavity 21 of the inner core group needs to be adjusted.

[0052] Please refer to Figure 1 、Figure 3 The packaging structure further includes an adjusting pad 3. Specifically, the adjusting pad 3 is arranged on the side of the inner lining main body 1 away from the notch structure 10. When packaging hollow fiber filters 5 of different lengths, it is only necessary to adaptively select whether to use the adjusting pad 3 or not. Specifically, after the inner lining main body 1 and the hollow fiber filter 5 are integrally installed in the packaging box 6, if there is a gap between the inner wall of the packaging box 6 and the inner lining main body 1, several adjusting pads 3 are added to fill the gap; if there is no gap or a small gap (the small gap here is a value within the allowable range) between the inner wall of the packaging box 6 and the inner lining main body 1, the adjusting pad 3 does not need to be used.

[0053] In a specific embodiment, the adjusting pad 3 and the side of the inner lining main body 1 away from the notch structure 10 can be attached. If multiple adjusting pads 3 are provided, adjacent adjusting pads 3 can also be arranged to be attached to each other. In specific use, the inner lining main body 1 and the hollow fiber filter 5 can be first installed in the packaging box 6, and then the adjusting pad 3 is put in.

[0054] In another specific embodiment, the adjusting pad 3 can be connected to the side of the inner lining main body 1 away from the notch structure 10. The connection here can be a snap connection. If multiple adjusting pads 3 are provided, adjacent adjusting pads 3 can also be arranged to be snap-connected. In specific use, the adjusting pad 3 and the inner lining main body 1 can be connected first and then the whole packaging structure is put into the packaging box 6.

[0055] On the basis that the packaging structure is provided with the adjusting pad 3, the length of the packaging box 6 is set to be longer. The longer here is set based on the longest length of the hollow fiber filter 5, which is convenient for the packaging structure to be suitable for the packaging of hollow fiber filters 5 with more length specifications. Please refer to Figure 7 The thickness of the inner lining main body 1 includes the depth of the notch structure 10 and the thickness T1 of the bottom of the notch. As Figure 2 If the length L2 dimension of the hollow fiber filter 5 is 200 mm to 1200 mm, then as Figure 10 the length L1 of the packaging box 6 > L2 max + 2T1. The greater than here means slightly greater, considering that the packaging box 6 itself has a certain thickness.

[0056] Taking a specific embodiment as an example, the inner lining main body 1, the inner core 2, and the adjusting pad 3 are all sponge bodies, which are easy to process and ensure that the hollow fiber filter 5 has a good buffering and shock-proof effect when installed in the packaging structure, ensuring reliable and effective protection of the hollow fiber filter 5 during transfer and transportation, ensuring the protection of the packaging bag 4, and avoiding the pollution of the filter by micro dust particles or microorganisms in the external environment.

[0057] The adjusting pad 3 can have different thicknesses, such as 2 cm, 3 cm, 4 cm, etc. One kind of thickness of the adjusting pad 3 can be adopted, or multiple adjusting pads 3 with combined thicknesses can be adopted.

[0058] The specific application occasion of the adjusting pad 3 is that the hollow fiber filter 5 is relatively short as a whole. If the inner lining main body 1 and the hollow fiber filter 5 are placed in the packaging box 6, there will be a gap between the inner lining main body 1 and the inner wall of the packaging box 6. Then, it is necessary to fill the gap through the cooperation of the adjusting pad 3 to ensure the stability of the hollow fiber filter 5.

[0059] Specifically, the adjusting pad 3 can be square, circular, or irregular in shape. When the packaging box 6 is square, the adjusting pad 3 is preferably square and its width and height are both consistent with the inside of the packaging box 6, so that the circumferential direction of the adjusting pad 3 fits the inner lining main body 1 and the inner wall of the packaging box 6, providing a comprehensive buffering and shock-absorbing effect.

[0060] If after two inner lining main bodies 1 and the hollow fiber filter 5 are installed in the packaging box 6 and the inner core 2 is used, the inner core 2 is arranged inside the inner lining main body 1. Just consider the remaining space in the length direction of the packaging box 6 after the inner lining main body 1 and the hollow fiber filter 5 are installed in the packaging box 6.

[0061] Taking the example that the adjusting pad 3 is attached to one side of the inner lining main body 1 and the adjacent adjusting pads 3 are also in an attached relationship. When there is a remaining space of 1 cm - 2 cm in the length direction of the packaging box, no adjusting pad 3 needs to be filled; when there is a remaining space of 2 cm - 3 cm in the length direction of the packaging box, an adjusting pad 3 with a thickness of 2 cm can be filled at one end; when there is a remaining space of 3 cm - 4 cm, an adjusting pad 3 with a thickness of 3 cm can be filled at one end; when there is a remaining space of 4 cm - 5 cm, two adjusting pads 3 with a thickness of 2 cm can be filled at both ends; when there is a remaining space of 5 cm - 6 cm, an adjusting pad 3 with a thickness of 2 cm can be filled at one end and an adjusting pad 3 with a thickness of 3 cm can be filled at the other end; when there is a remaining space of 6 cm - 7 cm, two adjusting pads 3 with a thickness of 3 cm can be filled at both ends; when there is a remaining space of 7 cm - 8 cm, two adjusting pads 3 with a thickness of 2 cm can be filled at one end and an adjusting pad 3 with a thickness of 3 cm can be filled at the other end. The above one end and the other end refer to the two ends in the length direction of the hollow fiber filter after the hollow fiber filter is placed in the packaging box 6.

[0062] Through the above packaging structure, the packaging of hollow fiber filters 5 with different thicknesses and the packaging of hollow fiber filters 5 with different lengths and sizes can be realized, so that this packaging structure can be applied to hollow fiber filters 5 of different specifications, improving the applicability of the packaging structure; in terms of cost, a set of molds can produce this packaging structure, and a set of packaging structures can be applicable to hollow fiber filters 5 of different specifications, saving processing costs, time costs, and raw material costs; in terms of use, there is only one packaging structure, which avoids errors and also avoids the sluggish waste of the packaging structure; in terms of material storage, management costs and storage costs are saved.

[0063] Based on any of the above embodiments, please refer to Figure 1 、 Figure 10 , the inner core group includes a plurality of inner cores 2, and the plurality of inner cores 2 are sequentially sleeved along the inner wall of the inner lining main body 1 to the center direction of the notch structure 10. The inner cavity 21 of the innermost inner core 2 and the notch structure 10 form an installation cavity.

[0064] Taking the example of meeting the use requirements of hollow fiber filters 5 with different thicknesses, different-sized installation cavities can be formed by the combination of one, two or more inner cores 2 and the inner lining main body 1 for the limit installation of hollow fiber filters 5 with different thicknesses.

[0065] The inner cores 2 are sleeved along the inner wall of the inner lining main body 1 to the center direction of the notch structure 10, and the inner cores 2 are sleeved from the outside to the inside. As the number of sleeved inner cores 2 increases, the size of the formed installation cavity gradually decreases, corresponding to the packaging of relatively thinner hollow fiber filters 5.

[0066] On the premise of setting a plurality of inner cores 2 to install the hollow fiber filter 5, the inner cavity 21 of the innermost inner core 2 and the notch structure of the inner lining main body form an installation cavity for the limit installation of the end of the relatively thinner hollow fiber filter 5. The relatively thinner here is relative to the hollow fiber filter 5 without using the inner core 2.

[0067] Based on any of the above embodiments, please refer to Figure 1 、 Figure 8 、 Figure 10 , the inner core 2 is of a C-shaped structure. When a plurality of inner cores 2 are sleeved in the inner lining main body 1, the openings 22 of the plurality of C-shaped structures are all communicated with the notch structure 10, so that the liquid inlet and outlet ports 51 can smoothly extend out of the openings 22 and be accommodated in the notch structure 10.

[0068] In addition, the sizes of the openings 22 of multiple C-shaped structures can be set to be the same or different. Here, the size refers to the width and length, and the length direction is parallel to the axial direction of the notch structure 10. When multiple C-shaped structures are sleeved, as long as the size relationship of the multiple openings 22 can avoid the interference of the inner core 2 at other positions with the inner core 2 at the center of the notch structure 10, ensure that the liquid inlet / outlet port 51 can smoothly extend out of the opening 22, and ensure that the multiple inner cores 2 and the lining main body 1 have good operation stability and reliability during joint operation.

[0069] Based on any of the above embodiments, please refer to Figure 5 、 Figure 6 , the notch structure 10 includes a first limiting groove 101, and the first limiting groove 101 is used for the installation of the end 52 of the hollow fiber filter 5 or for fitting the outer periphery of the inner core 2.

[0070] Please refer to Figure 5 、 Figure 2 , in the case where the hollow fiber filter 5 is relatively thick, the inner core 2 does not need to be provided. Then, the end 52 of the hollow fiber filter 5 is fitted through the first limiting groove 101, and the liquid inlet / outlet port 51 at the end of the hollow fiber filter 5 is installed and limited through the second limiting groove 102 communicated with the first limiting groove 101. Here, the installation and limitation refer to providing an installation space. On the basis of the fitting of the first limiting groove 101 and the end 52, the second limiting groove 102 does not need to fit the liquid inlet / outlet port 51 to form a reliable fixation of the whole hollow fiber filter 5.

[0071] Please refer to Figures 2 - 4 , in the case where the hollow fiber filter 5 is relatively thin, the inner core 2 needs to be provided. Then, the outer side of the inner core 2 is arranged to fit the first limiting groove 101, the inner side of the inner core 2 fits the end 52 of the hollow fiber filter 5, and the second limiting groove 102 provides an installation space for the installation of the liquid inlet / outlet port 51 at the end of the hollow fiber filter 5. That is, the inner cavity 21 of the inner core 2 and the second limiting groove 102 jointly form an installation cavity. In this case, if one inner core 2 is provided, since the inner core 2 fits inside the notch structure 10, the inner core 2 structure can be directly processed using the raw materials formed by stamping the notch structure 10 during processing, saving raw materials, being more environmentally friendly, and improving the effective utilization rate of resources from the production and manufacturing links.

[0072] In a specific embodiment, on the premise that the inner core 2 is not provided and the first limiting groove 101 is essentially a limiting hole, the aperture of the first limiting groove 101 is slightly larger than the diameter of the end 52. Specifically, the slightly larger value can be 1 cm, so that the first limiting groove 101 has a larger space to easily accommodate the end 52, facilitating the operator in the packaging process to more easily put the product with the packaging bag 4 into the lining main body 1;

[0073] Further, the width of the second limiting groove 102 is slightly larger than the maximum diameter of the liquid inlet / outlet port 51 to reduce the influence of the thickness of the packaging bag 4 and the operating resistance during installation. The specific value of this slight excess can be 1 cm. As Figure 6 shown, the direction indicated by W is the width direction of the second limiting groove 102;

[0074] Further, the total height formed by the first limiting groove 101 and the second limiting groove 102 is 1 cm greater than the overall height of the hollow fiber filter 5, which improves the convenience and labor-saving of the installation of the hollow fiber filter 5 while ensuring a reliable buffering effect and reliable installation for the hollow fiber filter 5. As Figure 6 and Figure 4 shown, the direction indicated by H is the total height direction formed by the first limiting groove 101 and the second limiting groove 102.

[0075] In another specific embodiment, on the premise that an inner core 2 is provided and the inner cavity 21 of the inner core 2 is essentially a limiting hole, the inner cavity 21 of the inner core 2 is slightly larger than the diameter of the end 52. The specific value of this slight excess can be 1 cm, which is convenient for having a relatively flexible space to accommodate the end 52 and enables the operator in the packaging process to more easily install the product with the packaging bag 4 into the inner lining main body 1;

[0076] Further, the width of the second limiting groove 102 is slightly larger than the maximum diameter of the liquid inlet / outlet port 51 to reduce the influence of the thickness of the packaging bag 4 and the operating resistance during installation. The specific value of this slight excess can be 1 cm; As Figure 6 shown, the direction indicated by W is the width direction of the second limiting groove 102;

[0077] Further, the total height of the installation cavity formed by the inner cavity 21 of the inner core 2 and the second limiting groove 102 is 1 cm greater than the overall height of the hollow fiber filter 5, which improves the convenience and labor-saving of the installation of the hollow fiber filter 5 while ensuring a reliable buffering effect and reliable installation for the hollow fiber filter 5. The total height direction of the installation cavity formed by the inner cavity 21 of the inner core 2 and the second limiting groove 102 is the same as Figure 6 and Figure 4 the direction indicated by H in

[0078] On the basis of any of the above embodiments, please refer to Figure 6 , the first limiting groove 101 and the second limiting groove 102 are connected by an arc transition to achieve a smooth transition, avoid sharp turns, and avoid scratching the operator.

[0079] On the basis of any of the above embodiments, the bottom of the first limiting groove 101 and the bottom of the second limiting groove 102 are both recessed outwardly to form a receiving groove 103 for receiving the heat-sealed edge of the packaging bag 4 of the hollow fiber filter 5. On the premise of not using the inner core 2, the sealed edge formed by the packaging bag 4 is received in the receiving groove 103. Specifically, the width of the receiving groove 103 is adapted to the thickness of the heat-sealed edge, and the depth of the receiving groove 103 is adapted to the width of the heat-sealed edge to accommodate the heat-sealed edge.

[0080] On the basis of any of the above embodiments, on the premise of using the inner core 2, a receiving groove 103 is provided on the inner wall of the installation cavity. Specifically, the bottom of the second limiting groove 102 and the inner wall of the inner core 2 are both recessed outwardly to form a receiving groove 103 for receiving the heat-sealed edge of the packaging bag 4 of the hollow fiber filter 5. Specifically, the width of the receiving groove 103 is adapted to the thickness of the heat-sealed edge, and the depth of the receiving groove 103 is adapted to the width of the heat-sealed edge to accommodate the heat-sealed edge.

[0081] On the basis of any of the above embodiments, whether the inner core 2 is used or not, the bottom of the first limiting groove 101, the bottom of the second limiting groove 102, and the inner wall of the inner core 2 are all recessed outwardly to form a receiving groove 103. When the inner core 2 needs to be provided, the receiving groove 103 on the inner wall of the inner core 2 is used to receive one heat-sealed edge of the packaging bag 4 of the hollow fiber filter 5; when the inner core 2 does not need to be provided, the receiving groove 103 at the bottom of the first limiting groove 101 is used to receive one heat-sealed edge.

[0082] On the basis of any of the above embodiments, please refer to Figure 1 , the length of the inner core 2 is equal to the depth of the groove opening structure 10. When the inner core 2 is used, the outer periphery of the inner core 2 is completely fitted with the groove opening structure 10 to ensure the stability after installation.

[0083] The depth of the groove opening structure 10 is less than the thickness of the inner lining main body 1. The groove opening structure 10 is a non-through structure. After the hollow fiber filter 5 is placed in the groove opening structure 10, its groove body can provide a good buffering effect, so that the inner lining main body 1 can wrap the end of the hollow fiber filter while realizing the limiting and buffering protection of the product. Specifically, the difference between the depth of the groove opening structure 10 and the thickness of the inner lining main body 1 is not limited, and it can be set according to the actual use effect.

[0084] On the basis of any of the above embodiments, guiding members are provided between the inner core 2 and the inner wall of the groove opening structure 10 and between adjacent inner cores 2 for positioning when forming the installation cavity.

[0085] For example, the inner core 2 is provided with a guiding groove, and the groove opening structure 10 is provided with a guiding protrusion. The cooperation between the guiding protrusion and the guiding groove can provide the positioning of the installation, ensure the accuracy of the installation of the inner core 2 in the groove opening structure 10, and ensure the reliable and stable packaging of the hollow fiber filter 5.

[0086] A guide member is provided between adjacent inner cores 2. When a multi-inner core structure is required for the packaging of the hollow fiber filter 5, a guide member is also provided between two adjacent inner cores 2 to ensure the accuracy of the combined installation of multiple inner cores 2, so as to ensure the reliable and stable packaging of the hollow fiber filter 5.

[0087] Based on any of the above embodiments, a guide groove is provided on one of two adjacent inner cores 2, and a guide protrusion is provided on the other. The cooperation between the guide protrusion and the guide groove can provide positioning for installation and ensure the accuracy of the installation of adjacent inner cores 2.

[0088] Specifically, the guide protrusion of one inner core 2 can slide from one end of the guide groove of its adjacent inner core 2 to the other end to realize the connection and separation between two adjacent inner cores 2. For example, if the guide groove is set as a U-shaped groove, the guide protrusion of one inner core 2 can slide into or out of the opening of the U-shaped groove of its adjacent inner core 2. When the guide protrusion slides into the U-shaped groove and contacts the bottom of the groove, two adjacent inner cores 2 are connected in place; when the guide protrusion slides out of the U-shaped groove, two adjacent inner cores 2 are separated.

[0089] Based on the above embodiments, the present utility model further provides a packaging assembly including the packaging structure described in any of the above embodiments. The packaging assembly further includes: a packaging box 6, and the packaging structure can be arranged inside the packaging box 6.

[0090] Please refer to Figure 10 , when packaging the relatively short hollow fiber filter 5, the adjustment pad 3 of the packaging structure needs to be used.
