Description

Technical Field

[0001] The present disclosure relates to the technical field of weaving equipment, and in particular to a weaving equipment and a method for weaving oxygenated membrane cloth. Background Art

[0002] Oxygenation membrane filaments are a kind of hollow semi-permeable membrane material, oxygen passes through the center, and blood flows through its outer wall. The membrane filaments themselves allow oxygen molecules and carbon dioxide molecules to pass through, while preventing water molecules and blood contents from passing through. The oxygenation membrane filaments are woven into oxygenation membrane cloth, which can be used as a key component of a hollow fiber oxygenator. Oxygenation membrane filaments have the following characteristics: first, the radial strength is low and can only withstand low-intensity pulling; second, the hollow fiber pipe is not pressure-resistant or resistant to strain, and excessive pressure cannot be applied to the functional area during weaving; third, since the oxygenation membrane cloth needs to be produced in a clean room, there are restrictions on the volume of the equipment.

[0081] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0082] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts, or a combination thereof disclosed in the present specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts, or a combination thereof exist or are added.

[0083] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0084] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0085] First, the weaving principle involved in the present disclosure is explained.

[0086] like Figure 1 As shown, the weft is led out from two weft boxes d and connected to form a U-shaped curve, the warp e is placed above the U-shaped curve, and then the weft knot is woven on the warp by exchanging the two weft boxes. Repeat the process of tying knots on the warp e to complete the weaving of the warp and weft.

[0087] The weaving equipment provided by the present invention is suitable for weaving materials that are not resistant to radial pressure and tension, such as oxygenated membrane yarns. In the method disclosed in the present invention, the oxygenated membrane yarns are used as warps. Since excessive pressure cannot be applied to the radial direction of the oxygenated membrane yarns, a traction method is used to pull a single oxygenated membrane yarn back and forth, which will not cause damage to the functional area of ​​the oxygenated membrane yarn. The weft yarns are knotted on the pulled oxygenated membrane yarns by cyclically exchanging two weft boxes, thereby realizing the weaving of oxygenated membrane yarn cloth.

[0088] like Figure 2 , Figure 3 , Figure 4As shown, the weaving device 10 includes: a frame body 11, a shell 12, two weft box mounting parts 13-1, 13-2, a warp traction assembly 14 and a driving mechanism. The shell 12 is fixed to the frame body 11, and forms a box body with the frame body 11. Two weft box mounting parts 13-1, 13-2, a warp traction assembly 14 and a driving mechanism are fixed inside the box body, wherein the two weft box mounting parts 13-1, 13-2 are arranged opposite to each other, movably connected to the frame body 11, and can be separated or closed under the action of external force. The warp traction assembly 14 includes: a second slide 141, a hollow traction member 142 and a thread throwing nozzle 143. The second slide 141 is fixed to the frame body 11, and the hollow traction member 142 is movably connected to the second slide 141 through, for example, a movable block 144, and the thread throwing nozzle 143 is located at the end of the hollow traction member 142. The hollow traction member 142 contains the warp yarn inside, which can prevent the warp yarn from being polluted by the external environment. Under the action of electromagnetic drive, the movable block 144 drives the hollow traction member 142 to move along the hollow traction member 142. Figure 3 The warp thread slides in the direction of the first path indicated by the middle arrow a, and the warp thread is pulled out along the first path from the thread throwing mouth 143. In the disclosed method, the first path is formed when the two weft box mounting parts 13-1 and 13-2 are separated.

[0089] The weft box mounting parts 13-1 and 13-2 are provided with outer guard plates 1311 to prevent the track from being exposed. The two weft box mounting parts 13-1 and 13-2 are respectively provided with a plurality of tracks for mounting the weft box. Figure 3 The figure schematically shows that the weft box d is mounted on the weft box mounting part 13-1, and when weaving the warp and weft, the weft box d is mounted on the weft box mounting parts 13-1 and 13-2 respectively. When the weft box mounting parts 13-1 and 13-2 are separated, a passage for the hollow traction member 142 to pass through is formed, and the weft box d is mounted on the separated weft box mounting parts 13-1 and 13-2 respectively. When the weft box mounting parts 13-1 and 13-2 are closed, the track of one weft box mounting part 13-1 can be spliced ​​with the track of another weft box mounting part 13-2 to form a plurality of closed-loop tracks. The two weft boxes d on the same closed-loop track exchange positions to weave weft knots on the pulled-out warp to complete the weaving of the warp and weft. By cyclically alternating the positions of the two weft boxes d, the number of knots can be adjusted, and then the distance between the two woven warps can be adjusted to obtain woven products with different warp spacings.

[0090] Figure 5 A schematic diagram of a closed-loop track disclosed in the present invention is shown. Figure 5 As shown, the track set on the wire box mounting part 13-1 is composed of parallel long tracks a 1 , short track b 1 and on the long track a 1 , short track b 1The inclined orbit between 1 Composition, inclined orbit c 1 With long track a 1 The angle is preferably 45°. The track arranged on the wire box mounting member 13-2 is composed of parallel long tracks a 2 , short track b 2 and on the long track a 2 , short track b 2 The inclined orbit between 2 When the two weft box mounting parts 13-1 and 13-2 are closed, the multiple tracks arranged on the weft box mounting parts 13-1 and 13-2 are spliced ​​into multiple closed loop tracks h 1 、h 2 ……h 20 It can be understood that the figure schematically shows 20 closed-loop tracks, and those skilled in the art can flexibly adjust the number of closed-loop tracks as needed, and the present disclosure does not limit this. 9 For example, it is divided into a straight part (long track a 1 Shorten track b 2 Partial, short track b 1 Extended track 2 part) and turnout part (inclined track c 1 Partial, inclined track c 2 part).

[0091] The closed-loop track is adapted to a weft box d having one thread foot, two thread feet, and in particular two thread feet d 1 ,d 2 In this case, the volume of the weft box can be increased so that a sufficiently long fabric can be woven at one time. Fig. 9 , Fig. 9 The schematic diagram of the principle of the exchange movement of two weft boxes d is shown, as Fig. 9 As shown, the weft box d moves from the straight section to the switch section in the respective tracks, and one leg d of the two weft boxes d 1 Located in the straight part, another line foot d 2 Located in the switch part, after passing through the switch part, the two weft boxes d exchange positions to realize the knotting of the weft. After exchanging positions, one weft box d moves from the initial track to the corresponding other track, and the above process is repeated for the next position exchange.

[0092] In some cases, when the weft box has a line foot, the track set on the line box mounting component 13-1 can also be a semicircular track, a V-shaped track or a track of other shapes. As long as a closed-loop track can be formed when the two weft box mounting components 13-1 and 13-2 are closed, the positions of the two weft boxes can be exchanged. This disclosure will not be elaborated here.

[0093] Furthermore, in order to facilitate the simultaneous driving of the position exchange of the weft boxes on different tracks, the shapes of the multiple tracks are preferably the same, and are arranged at equal intervals on the weft box mounting parts 13-1 and 13-2. Of course, the shapes of the multiple tracks can also be different or partially the same, in which case it is only necessary to drive the weft boxes on different tracks to exchange positions. In addition, the spacing between the multiple tracks can also be flexibly adjusted as needed, and the present disclosure does not limit this.

[0094] The following is based on Figure 5 The closed-loop track shown further illustrates the implementation method of driving the weft box position exchange.

[0095] like Figure 6 , Figure 7 , Figure 8 As shown, the driving mechanism includes: two comb plates 14-1, 14-2 and two push plates 15-1, 15-2, wherein the weft box mounting member 13-1, the comb plates 14-1, and the push plates 15-1 are arranged in layers, and the weft box mounting member 13-2, the comb plates 14-2, and the push plates 15-2 are arranged in layers, and there is a gap between two adjacent layers for relative displacement. In the disclosed method, schematically, the weft box mounting members 13-1, 13-2 are located at the top layer, the comb plates 14-1, 14-2 are located at the middle layer, and the push plates 15-1, 15-2 are located at the bottom layer. In some cases, the comb plates 14-1, 14-2 may be located at the bottom layer, and the push plates 15-1, 15-2 are located at the middle layer, and the present disclosure does not limit this.

[0096] like Figure 3 As shown, two comb plates 14-1 and 14-2 are arranged opposite to each other, movably connected to the frame body 11, and can be separated or closed under the action of external force; and two push plates 15-1 and 15-2 are arranged opposite to each other, movably connected to the frame body 11, and can be separated or closed under the action of external force. In the disclosed method, the first path is formed when the two weft box mounting parts 13-1 and 13-2, the two comb plates 14-1 and 14-2 and the two push plates 15-1 and 15-2 are separated.

[0097] Please refer to Figure 7 , Fig.10 The comb teeth of the two comb plates 14-1 and 14-2 can mesh with each other, and each comb tooth is used to push a weft box to move in the straight part composed of the long track and the short track. When the two comb plates 14-1 and 14-2 are closed, the adjacent comb teeth each push the thread feet of the weft box d mounted on the weft box mounting parts 13-1 and 13-2, and push it to position 1a.

[0098] Please refer to Figure 5 , Figure 8 , Fig.11The first guide member 1313 is respectively provided on the two weft box mounting members 13-1 and 13-2. Specifically, a mounting hole 1312 is provided in the turnout part, and the first guide member 1313 is fixed in the mounting hole 1312. The push plates 15-1 and 15-2 cooperate with the first guide member 1313 to push the thread foot of the weft box d from the long track to the short track via the inclined track, and push it to the position 1b. It should be noted that Figure 5 Only one first guide member 1313 is schematically shown. It can be understood that the first guide member 1313 is arranged at the switch part of each track.

[0099] By closing the weft box mounting parts 13-1 and 13-2, the tracks respectively arranged thereon are spliced ​​into a closed-loop track, and then the comb plates 14-1 and 14-2 are closed to push the thread feet of the two weft boxes on the same closed-loop track, and the weft boxes on the respective tracks are moved in a direction away from each other to the switch part, after which the moving directions of the two weft boxes are reversed, and then the push plates 15-1 and 15-2 are closed to push the thread feet of the two weft boxes through the switch part, thereby completing a weft weaving process on the warp. Then the weft box mounting parts 13-1 and 13-2, the comb plates 14-1 and 14-2, and the push plates 15-1 and 15-2 are driven to separate, and the warp traction assembly 14 pulls the same warp back, and then the above-mentioned process of closing the weft box mounting parts 13-1 and 13-2, the comb plates 14-1 and 14-2, and the push plates 15-1 and 15-2 is repeated to carry out the next weft weaving process.

[0100] The weaving device provided by the present invention can be driven by an electromagnetic drive, a hydraulic drive or other mechanical drive methods to open / close the weft box mounting parts 13-1, 13-2, the comb plates 14-1, 14-2, and the push plates 15-1, 15-2. In addition, it can be driven by one or more power sources. For example, one power source can simultaneously drive the weft box mounting parts 13-1, 13-2, the comb plates 14-1, 14-2, and the push plates 15-1, 15-2 to open / close, or one power source can drive the weft box mounting parts 13-1, 13-2, the comb plates 14-1, 14-2 to open / close, and another power source can drive the push plates 15-1, 15-2 to open / close. Further, taking the weft box mounting parts 13-1 and 13-2 as an example, the weft box mounting part 13-1 can be fixed and only the weft box mounting part 13-2 can be driven to open / close. Of course, the weft box mounting parts 13-1 and 13-2 can also be driven to open / close with each other at the same time, and the present disclosure does not impose any restrictions on this.

[0101] Next, an embodiment of the present disclosure for simultaneously driving the weft box mounting members 13 - 1 , 13 - 2 , the comb plates 14 - 1 , 14 - 2 , and the push plates 15 - 1 , 15 - 2 to open / close will be described.

Among them, the three slide rails 161 are fixed to the frame body 11 and are arranged in layers. The weft box mounting parts 13-1, 13-2, comb plates 14-1, 14-2, and push plates 15-1, 15-2 are respectively fixed to a slider 162. Considering that the layer gap between the comb plates 14-1, 14-2 and the push plates 15-1, 15-2 and the weft box mounting parts 13-1, 13-2 should not be too large, and to avoid the weft box feet being too long, the push plates 15-1, 15-2 can be fixed to the slider 162 after being bent (such as Figure 6 In some cases, the adapter 164 may be used to fix the slider 162 (eg Fig.12 The present disclosure does not limit this.

[0103] like Fig.14 , Fig.15 As shown, the driving mechanism also includes: a second sliding assembly 17, and the second sliding assembly 17 includes a track plate seat 171 and a first track plate 172. Among them, the track plate seat 171 is provided with a first slide 1711, a first channel 01a, a second channel 01b, and a third channel 01c, and the first track plate 172 is movably connected to the first slide 1711. The first track plate 172 is provided with a first track 02a, a second track 02b, and a third track 02c. Taking the weft box mounting member 13-1 as an example, the end of the second guide member 163 on the slider 162 corresponding to the weft box mounting member 13-1 passes through the first channel 01a and is placed in the first track 02a. Similarly, the comb plate 14-1 and the push plate 15-1 also pass through the second channels 01b and 01c respectively adapted by the second guide member 163 and are placed in the second tracks 02b and 02c respectively. In the disclosed method, two second slide rails 1711 are arranged on the track plate seat 171, and the corresponding number of first track plates 172 is two (only the first track plate on the left side is shown in the figure), which are respectively connected to the two second slide rails 1711, and the weft box mounting component 13-1, the comb plate 14-1, and the push plate 15-1 are driven by one first track plate 172, and the weft box mounting component 13-2, the comb plate 14-2, and the push plate 15-2 are driven by another first track plate 172.

[0104] like Fig.16 , Fig.17As shown, the driving mechanism further includes: a gear linkage mechanism 18, which includes a rocker 181, a power input shaft 182, a driving wheel 183, a driven wheel 184 and a connecting rod 185. Among them, the rocker 181 is connected to the power input shaft 182, the power input shaft 182 is provided with a driving wheel 183, the driven wheel 184 is meshed with the driving wheel 183, the number of the driven wheels 184 is two, each driven wheel 184 is movably connected to a connecting rod 185, and the other end of the connecting rod 185 is rotatably connected to the first track plate 172.

[0105] The second sliding component 17 is movably connected to the first sliding component 16, and the gear linkage mechanism 18 is used to drive the second sliding component 17 to move in the first direction, and drive the first sliding component 17 to move in the second direction, so as to simultaneously drive the weft box mounting parts 13-1, 13-2, the comb plates 14-1, 14-2, and the push plates 15-1, 15-2 to open / close.

[0106] Specifically, the driven wheel 184 is driven to rotate by the hand-cranked rocker 181, and the connecting rod 185 drives the first track plate 172 to reciprocate on the first slide 1711 as the driven wheel 184 rotates. The second guide member 161 placed in the first track 02a, the second track 02b, and the third track 03c reciprocates under the limiting action of the corresponding track, thereby driving the slider 162 and the weft box mounting members 13-1, 13-2, the comb plates 14-1, 14-2, and the push plates 15-1, 15-2 arranged on the slider 162 to open / close simultaneously. Among them, the first track 02a and the second track 02b can be one-way slides, and the third track 03c can be a closed-loop track. The corresponding path can be designed according to the actual situation, and this disclosure will not elaborate on this.

[0107] Furthermore, the weaving device of the present disclosure can also be provided with two thread gathering plates 19-1 and 19-2 as required to adjust the spacing of the weft threads. Fig.18 As shown, the wire gathering plates 19 - 1 and 19 - 2 are provided with a plurality of comb teeth with a small spacing, and the spacing between adjacent comb teeth can be flexibly adjusted according to actual conditions, and the present disclosure does not impose any limitation on this.

In the disclosed method, the first path is formed by the passage when the two weft box mounts 13-1, 13-2, the two comb plates 14-1, 14-2 and the two push plates 15-1, 15-2 and the two thread gathering plates 19-1, 19-2 are separated.

[0109] In addition, the present disclosure also provides an embodiment of simultaneously driving the weft box mounting parts 13-1, 13-2, the comb plates 14-1, 14-2, the push plates 15-1, 15-2, and the thread gathering plates 19-1, 19-2 to open / close.

[0110] Specifically, the thread gathering plates 19-1 and 19-2 are connected to the first sliding assembly 16. For details, please refer to the fixing methods of the weft box mounting parts 13-1 and 13-2, the comb plates 14-1 and 14-2, and the push plates 15-1 and 15-2, which will not be described in detail here. Fig.14 , Fig.15 As shown, the second sliding assembly 17 further includes: a second track plate 173, movably connected in the first slideway 1711, a fourth track 02d is provided on the second track plate 173, and a fourth channel 01d is provided on the track plate seat 171. Taking the wire gathering plate 19-1 as an example, the end of the second guide member 163 on the slider 162 corresponding to the wire gathering plate 19-1 passes through the fourth channel 01d and is placed in the fourth track 02d. Fig.16 , Fig.17 As shown, the second track plate 173 is also provided with a fifth channel 02e, and the gear connection mechanism 18 further includes: a third guide member 186, one end of which is placed in the fifth channel 02e, and the driven wheel 183 is Fig.17 When the initial position rotates 1 / 4 circle in the direction of the arrow, the third guide member 186 moves from the center to the end b in the fifth channel 02e. When the driven wheel 183 rotates 1 / 2 circle, the third guide member 186 returns to the initial position. The driven wheel 183 continues to rotate, and the third guide member 186 moves from the initial position to the end c, and then returns to the initial position, thereby completing the separation / closing process of the weft box mounting parts 13-1, 13-2, comb plates 14-1, 14-2, push plates 15-1, 15-2, and thread gathering plates 19-1, 19-2.

[0111] The weaving device provided by the embodiment of the present disclosure is suitable for weaving materials that are radially non-pressure-resistant and non-strain-resistant, especially for weaving oxygenated membrane filaments. The oxygenated membrane filaments are drawn out by traction, which will not cause damage to the functional area of ​​the oxygenated membrane filaments. Specifically, when pulling the warp, it is necessary to pass through the first path formed between the two weft box mounts, so as to place the warp above the weft drawn out from the two weft boxes, and then by closing the two weft box mounts and exchanging the two weft boxes on the closed-loop track, the weft knots are woven on the warp to achieve the weaving of the oxygenated membrane cloth.

[0112] Based on the same or similar design concept, the present disclosure also provides a method for weaving oxygenated membrane cloth using the weaving equipment described above.

[0113] The method for weaving oxygenated membrane silk cloth comprises the following steps:

[0114] a passage forming a first path;

[0115] placing the oxygenation membrane filament into the hollow traction rod and leading it out along the first path;

[0116] The weft boxes are driven to exchange positions on the closed-loop track, thereby tying knots on the oxygenated membrane filaments;

[0117] Repeat the process of pulling the oxygenation membrane wire and tying knots on the oxygenation membrane wire to complete the weaving of the oxygenation membrane wire cloth. According to an embodiment of the present disclosure, the method for weaving the oxygenation membrane wire cloth also includes:

[0118] The step of controlling the number of knots tied on the oxygenation membrane filaments. According to an embodiment of the present disclosure, the method of weaving the oxygenation membrane filament cloth further includes:

[0119] The step of gathering the wires using a gathering board.

[0120] Please combine Figure 1 , Figure 2 In the disclosed method, the process of weaving the oxygenated membrane cloth is as follows:

[0121] Weft boxes are mounted on the weft box mounting parts 13-1 and 13-2 respectively. The weft boxes have wefts built in them. The wefts led out of the two weft boxes exchanged on the same closed-loop track are knotted, and the two ends of the wefts are passed through the gathering plates 19-1 and 19-2. The same operation is performed on the two weft boxes on the other closed-loop tracks.

[0122] By manually turning the rocker 181, the two weft box mounting parts 13-1, 13-2, the two combing plates 14-1, 14-2, the two pushing plates 15-1, 15-2, and the two thread gathering plates 19-1, 19-2 are separated to form a first path. At this time, the hollow traction member 142 is controlled to move along the first path, and a warp thread (oxygenated membrane thread) is pulled out from the thread throwing nozzle 143;

[0123] Continue to rotate the rocker 181, and drive the two weft box mounting parts 13-1, 13-2, the two comb plates 14-1, 14-2, the two push plates 15-1, 15-2, and the two thread gathering plates 19-1, 19-2 to close through the first track plate 172 and the second track plate 173, wherein the two weft box mounting parts 13-1, 13-2 are closed to form a closed-loop track for the two weft boxes to exchange positions, the two comb plates 14-1, 14-2 are closed to push the two weft boxes to move from the straight part of their respective tracks to the turnout part, and the two push plates 15-1, 15-2 are closed to push the two weft boxes to move from the turnout part of their respective tracks to the straight part, at this time, the positions of the two weft boxes are exchanged, and the wefts drawn out of the two weft boxes are knotted on the warp, completing a weaving process;

[0124] The two comb plates 14-1 and 14-2 continue to push the two weft boxes to move to the straight part of the other track, and continue to rotate the rocker 181 in the same rotation direction. The two weft box mounts 13-1 and 13-2, the two comb plates 14-1 and 14-2, the two push plates 15-1 and 15-2, and the two wire gathering plates 19-1 and 19-2 are separated again to form the first path. At this time, the hollow traction member 142 is controlled to pull the same warp back along the first path, repeating the above-mentioned process of knotting the weft on the warp to complete the next weft and weft weaving process. In the disclosed method, after completing a weaving process, the first track plate 172 and the second track plate 173 continue to be controlled to drive the two weft box mounts 13-1, 13-2, the two comb plates 14-1, 14-2 and the two push plates 15-1, 15-2, and the two wire gathering plates 19-1, 19-2 to open. After the first path is formed, the hollow traction member 142 is not driven to move along the first path, but continues to repeat knotting on the original warp, so as to adjust the spacing between the currently pulled warp and the next pulled warp, and weave oxygenated membrane silk cloth that meets various needs.

[0125] In the disclosed method, a gathering plate is used to gather the threads to adjust the spacing between the weft threads. When the weft thread spacing can meet the requirements of materials such as oxygenated membrane cloth, this step is not a necessary step. Those skilled in the art can flexibly choose according to actual conditions, which will not be elaborated here.

[0126] For other technical details involved in the embodiments of the present disclosure, reference can be made to the technical content of the weaving equipment and will not be elaborated here.

[0127] The above description is only a preferred embodiment of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present disclosure is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present disclosure (but not limited to) by each other.
