Description

Technical Field

[0001] The invention relates to the field of medical device manufacturing equipment, and in particular to a weaving machine for balloon-shaped cylindrical netting. Background Art

[0002] As a medical intervention device, the balloon needs to enter the human body to support human tissues when used, so the support strength of the balloon is required to be relatively high. Currently, the balloons on the market are all formed by blow molding. Since this type of balloon has no net basket on the surface, there is a risk of bursting when the pressure inside the balloon is too high.

[0003] In order to increase the strength of the balloon, a layer of net is now put on the outside of the balloon. The constraint of the net on the outside of the balloon can effectively prevent the balloon from bursting.

[0004] The existing problem is that it is difficult to manufacture the balloon-shaped cylindrical net 1. Figure 1 As shown, the balloon-shaped cylindrical mesh 1 includes a large diameter section 11 in the middle, tapered diameter-reducing sections 12 at both ends of the large diameter section 11, and a small diameter section 13 on the outside of the diameter-reducing section 12. Since the width (the width is also called the width, which refers to the full width of the fabric, that is, the actual width of the fabric, the distance between the outermost warp yarns on both sides of the fabric) of this balloon-shaped cylindrical mesh is constantly changing, the width of the fabric woven by the traditional weaving machine is fixed and the width-reducing operation cannot be achieved. Therefore, the weaving machines for balloon-shaped meshes currently on the market can only be used to weave meshes with fixed widths. For example, the prior patent, CN217517135U, a high-performance balloon weaving device, the weaving device disclosed in the patent can only weave meshes with fixed widths and cannot produce meshes with variable diameter structures. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a weaving machine for balloon-shaped cylindrical nets to solve the current problems of great difficulty in producing balloon-shaped cylindrical nets and low production efficiency.

[0010] The palm lifting mechanism is suitable for lifting and lowering each warp thread passing through according to the steps of the cylindrical net palm lifting, and each warp thread is separated up and down to form a shed for the weft thread to pass through;

[0011] A weaving area is formed between the palm lifting mechanism and the thread pressing mechanism, the weft beating mechanism is located in the weaving area, and the weft diameter changing mechanism is arranged at the front side of the weft beating mechanism and is suitable for moving forward and backward along with the weft beating mechanism;

[0012] The weft diameter-changing mechanism is suitable for adjusting the width of each warp yarn to adjust the width of the tubular net;

[0013] The beating mechanism is suitable for driving the shuttle to move in the weft direction and the warp direction in the weaving area, so that the shuttle carries the weft thread and each warp thread to weave a tubular mesh;

[0042] The present invention will now be further described in conjunction with specific embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0043] like Figures 1 to 18 As shown, a balloon-shaped cylindrical net weaving machine includes

[0044] A frame, on which a wire feeding mechanism 7, a palm lifting mechanism 2, a weft diameter changing mechanism 4, a weft beating mechanism 3, a wire pressing mechanism 5 and a winding mechanism 6 are arranged in sequence from front to back;

[0045] The wire feeding mechanism 7 is suitable for conveying a plurality of warp threads toward the palm lifting mechanism 2, and each warp thread sequentially passes through the palm lifting mechanism 2, the weft diameter changing mechanism 4, the beating mechanism 3, the wire pressing mechanism 5 and the winding mechanism 6;

[0046] The palm lifting mechanism 2 is suitable for lifting and lowering each warp thread passing through according to the steps of the cylindrical net palm lifting, and each warp thread is separated up and down to form a shed for the weft thread to pass through;

[0047] A weaving area is formed between the palm lifting mechanism 2 and the thread pressing mechanism 5, the beating-up mechanism 3 is located in the weaving area, and the weft diameter changing mechanism 4 is arranged at the front side of the beating-up mechanism 3 and is suitable for moving forward and backward along with the beating-up mechanism 3;

[0048] The weft diameter-changing mechanism 4 is suitable for adjusting the width of each warp yarn to adjust the width of the tubular net;

[0049] The beating mechanism 3 is suitable for driving the shuttle 34 to move in the weft direction and the warp direction in the weaving area, so that the shuttle 34 can weave a cylindrical mesh with the weft and each warp.

[0050] The wire pressing mechanism 5 is suitable for limiting the height of each warp thread, and the woven tubular mesh passes through the wire pressing mechanism 5;

[0051] The winding mechanism 6 is connected to the cylindrical woven net and winds up the woven cylindrical woven net.

[0052] Specifically, as an optional implementation in this embodiment, Figure 3 and Figure 4 As shown, the palm lifting mechanism 2 includes

[0053] Four brown frame components, each brown frame component is overlapped in the front-to-back direction; from front to back, they are the first brown frame component 21, the second brown frame component 22, the third brown frame component 23 and the fourth brown frame component 24;

[0054] Each palm frame assembly includes a palm frame and a linear module. A plurality of palm rods 211 are arranged in the palm frame. The palm rods 211 are provided with thread holes for the warp threads to pass through.

[0055] The linear module connects the palm frame and the frame to drive the palm frame assembly to move up and down;

[0056] Each palm frame assembly is alternately raised and lowered according to a preset step to drive the warp threads in each palm frame assembly to form a shed.

[0057] The steps of lifting the palm oil by the palm oil lifting mechanism 2 are as follows:

[0058] Step 1: The third palm frame assembly 23 is lifted, and the other palm frame assemblies remain stationary, driving the inner warp opening of the third palm frame assembly 23;

[0059] Step 2: The first, third and fourth palm frame assemblies are lifted, and the second palm frame assembly 22 remains stationary, driving the warp openings in the first, third and fourth palm frame assemblies;

[0060] Step 3: The fourth palm frame assembly 24 is lifted, and the other palm frame assemblies remain stationary, driving the inner warp of the fourth palm frame assembly 24 to open;

[0061] Step 4: The second, third and fourth palm frame assemblies are lifted, and the first palm frame assembly 21 remains stationary, driving the inner warp openings of the second, third and fourth palm frame assemblies;

[0062] Repeat the above four steps.

[0063] Through this palm raising step, it can be ensured that the woven net is a cylindrical net.

[0064] Specifically, as an optional implementation in this embodiment, Figures 5 to 10 As shown, the beating mechanism 3 includes

[0065] The slide 31 is arranged in the weaving area of ​​the frame and is suitable for sliding forward and backward in the weaving area;

[0066] A first mounting plate 32 is disposed on the slide seat 31. A wiring hole 321 is provided on the first mounting plate 32. Each warp thread passes through the wiring hole 321.

[0067] Two shuttle seats 33 are respectively located on both sides of the wiring hole 321 and are fixedly connected to the first mounting plate 32. A sliding groove for accommodating the shuttle 34 is provided in the shuttle seat 33;

[0068] A shuttle 34, on which a weft thread wheel 341 is mounted, and the weft thread on the thread wheel passes through the shuttle 34;

[0069] The driving mechanism 35 is in driving connection with the shuttles 34 and is suitable for driving the shuttles 34 to move back and forth between the two shuttles 34 .

[0070] In this embodiment, the shuttle seat 33 includes an upper guide seat 331 and a lower guide seat 332 , and a slide groove is formed between the upper guide seat 331 and the lower guide seat 332 .

[0071] In this embodiment, the slide 31 is driven by two left and right linear modules, and the left and right linear modules move synchronously, so that the slide 31 is stably moved forward and backward on the frame.

[0072] The purpose of the slide 31 moving forward and backward in the weaving area is to push the threaded weft thread backward to a predetermined position and cooperate with the winding mechanism 6 at the rear end to control the distance between two adjacent weft threads.

[0073] Specifically, Fig.10 As shown, the driving mechanism 35 includes

[0074] The large rack 351 is arranged to slide left and right in the weft direction on the slide seat 31;

[0075] Four transmission gears 353, two transmission gears 353 are respectively provided on each shuttle seat 33;

[0076] A small rack 352 is fixedly arranged below the shuttle 34, and the small rack 352 forms a transmission match with the large rack 351 through a transmission gear 353;

[0077] When the large rack 351 moves back and forth on the slide 31 , it drives the four transmission gears 353 to rotate synchronously, thereby driving the shuttle 34 to move between the two shuttle seats 33 . 1

[0078] The large rack 351 is also driven by a linear module, which is installed below the slide 31. The linear module is connected to the large rack 351 through a connecting plate, and the linear module drives the large rack 351 to move back and forth.

[0079] Working principle of beating-up mechanism 3:

[0080] Each warp thread passes through the thread routing hole 321, and two shuttle seats 33 are located on both sides of each warp thread. The lifting step is performed according to the preset steps, so that each warp thread opens the shuttle mouth according to the preset steps. The driving mechanism 35 drives the large rack 351 to move back and forth, and the large rack 351 rotates synchronously through four transmission gears 353. Figure 5 As shown, when the shuttle 34 is located in the slide groove of the shuttle seat 33, the small rack 352 is engaged with the two transmission gears 353 in the shuttle seat 33; Figure 6As shown in FIG. 1 , when the shuttle 34 drives the weft to pass through the shed openings of each warp in the weft direction, the small rack 352 meshes with a transmission gear 353 in the shuttle seat 33 until the shuttle 34 moves to the shuttle seat 33 on the other side, and the shuttle 34 meshes with two transmission gears 353 in the shuttle seat 33 on the other side. At this time, the beating mechanism 3 completes the routing of the weft, that is, Figure 7 The large rack 351 moves back and forth, driving the shuttle 34 to move back and forth between the two shuttle seats 33, so as to realize the weft reciprocating routing of the weft.

[0081] Specifically, as an optional implementation in this embodiment, Figures 11 to 13 As shown, the weft-direction diameter-changing mechanism 4 includes

[0082] The second mounting plate 41 is located in front of the first mounting plate 32. A plurality of linear modules are arranged between the second mounting plate 41 and the first mounting plate 32 to enable the second mounting plate 41 to perform lifting motion. A reed mounting hole 411 is provided on the second mounting plate 41.

[0083] The first reed 42 is fixedly arranged in the reed mounting hole 411. The first reed 42 is provided with a first wire groove group 43. The first wire groove group 43 includes a wide-distance portion 431, a variable-distance portion 432, and a narrow-distance portion 433. The wire groove spacing in the wide-distance portion 431 is greater than the wire groove spacing in the narrow-distance portion 433. The wire groove spacing in the variable-distance portion 432 gradually decreases from top to bottom.

[0084] The number of the first line grooves corresponds to the number of the warp threads, and each warp thread passes through the first line grooves respectively.

[0085] When it is necessary to weave the small diameter section 13 of the balloon, the linear module drives the first reed 42 to lift, so that the warp threads are gathered to the narrow spacing portion 433. At this time, the spacing between the warp threads is the smallest, and the weft beating mechanism 3 drives the weft threads to weave. At this time, the weaving area is woven with the small diameter section 13 of the balloon; during the weaving process, each warp thread is slowly pulled backward by the winding mechanism 6, and the first reed 42 also slowly moves downward until the warp threads enter the variable spacing portion 432, and the spacing between the warp threads begins to slowly increase. At this time, the weaving area is in the variable diameter section 12 of the weaving balloon, and finally the warp threads enter the wide spacing portion 431. At this time, the spacing between the warp threads is the largest, and the weaving area is in the large diameter section 11 of the weaving balloon.

[0086] Specifically, as an optional implementation in this embodiment, Fig.14 As shown, the wire pressing mechanism 5 includes

[0087] A wire pressing base 51 is fixedly arranged on the frame, and each warp wire passes through the upper end surface of the wire pressing base 51. A bolt through hole is provided on one side of the wire pressing base 51, and the bolt through hole is a long slot hole;

[0088] A pressing plate 52, one end of which is rotatably connected to the wire pressing base 51;

[0089] The locking bolt 53 passes through the bolt through hole and is connected to the pressure plate 52. The locking bolt 53 is suitable for moving up and down in the bolt through hole.

[0090] After the locking bolt 53 locks the pressing plate 52, the limiting pressing plate 52 is turned over on the pressing base 51, and the woven balloon is moved away from under the pressing plate 52. The pressing plate 52 is used to limit the height of the warp threads, so that the beating mechanism 3 can be installed at a set height according to the height of the warp threads, so that the shuttle 34 can accurately pass through the shed formed by each warp thread.

[0091] Specifically, as an optional implementation in this embodiment, Figure 15 to Figure 16 As shown, the winding mechanism 6 includes

[0092] Coiler frame 61;

[0093] A plurality of driven rollers 62 are arranged on the winding frame 61;

[0094] The driving roller 63 is arranged on the winding frame 61;

[0095] The elastic mechanism 64 is arranged on the winding frame 61 and connected to the pressing roller 645 . The elastic mechanism 64 drives the pressing roller 645 to elastically press the belt driving roller 63 .

[0096] The active roller 63 is driven by a servo motor to rotate. The moving speed of the active roller 63 drives the weaving net to match the weaving speed of the weaving area. Whenever a weft is driven in, the active roller 63 drives the warp to move backward a certain distance to prepare for the beating mechanism 3 to drive in the next weft. The winding speed of the active roller 63 determines the spacing between two adjacent wefts in the weaving net.

[0097] Specifically, Fig.16 As shown, the elastic mechanism 64 includes

[0098] A roller seat 641, the middle of which is connected to the coiling frame 61 via a distribution shaft, and a pressing roller 645 is installed on the upper end thereof;

[0099] The balance block 642 has one end connected to the tension spring 643 and the other end forming an upper abutting portion 6421 and a lower abutting portion 6422, both of which abut against the roller seat 641, the upper abutting portion 6421 is located above the pin shaft, and the lower abutting portion 6422 is located below the pin shaft;

[0100] The tension spring 643 has its lower end connected to an adjusting screw 644 , and the adjusting screw 644 is connected to the winding frame 61 , and its upper end is connected to the tension spring 643 .

[0101] The tension spring 643 is located below the active roller 63, pulling the lower abutment portion 6422 of the balancing block 642 to press against the roller seat 641, so that the pressing roller 645 on the roller seat 641 can press the active roller 63, thereby pressing the woven net to achieve stable winding of the woven net.

[0102] Specifically, as an optional implementation in this embodiment, Figure 1 Fig.17 as well as Fig.18 As shown, the wire feeding mechanism 7 includes

[0103] A warp line wheel 71 is arranged on the frame;

[0104] A wire feeding frame 72, on which a plurality of tension rods 73 and a second reed 74 are arranged;

[0105] The second reed 74 is provided with a second wire groove group 75;

[0106] After passing around each tension rod 73 , each warp thread passes through the second thread groove group 75 .

[0107] The function of the second line groove group 75 is to ensure that each warp thread is separated from each other so that each warp thread passes through each palm rod 211 to avoid mutual influence between the warp threads.

[0108] In this embodiment, 72 warps are arranged on the warp wheel 71, and the number of warps can be adjusted according to the size of the finished mesh. At the same time, the number of second slots in the second slot group 75 is also 72, and 72 warps pass through the palm lifting mechanism 2, and 18 warps pass through each palm lifting assembly, and the number of first slots in the first reed 42 is also 72.

[0109] The method of using the above-mentioned braiding machine to weave the balloon-shaped cylindrical braided net 1 is specifically as follows:

[0110] like Figure 1 As shown, the balloon-shaped cylindrical net 1 includes a middle large diameter, two variable diameter sections 12 and two small diameter sections 13. To weave a finished balloon-shaped cylindrical net 1, the first reed 42 of the weft variable diameter mechanism 4 needs to control each warp thread to pass through the narrow pitch portion 433, the variable pitch portion 432, the wide pitch portion 431, the variable pitch portion 432 and the narrow pitch portion 433 in sequence.

[0111] The 72 warp threads on the warp thread wheel 71 pass through the second reed 74 of the winding mechanism, the second reed 74 of the palm lifting mechanism 2, the first reed 42 of the weft diameter changing mechanism 4, the wiring hole 321 of the beating-up mechanism 3, the thread pressing mechanism 5 and the winding mechanism 6 in sequence. The winding mechanism tightens each warp thread and drives the warp thread to move backward. The thread pressing mechanism 5 controls the height of each warp thread in the weaving area so that the beating-up mechanism 3 can stably thread the weft thread.

[0112] After the 72 warp threads pass through the second thread groove group 75, the 72 warp threads are dispersed to avoid being entangled with each other; the 72 warp threads are inserted into the palm lifting mechanism 2, so that the palm lifting mechanism 2 can stably lift the palm, and each palm lifting component passes through 18 warp threads. When the palm lifting mechanism 2 starts the first step of palm lifting, the third palm frame component 23 drives the 18 warp threads in its palm frame to lift, and a shed is formed between the 18 warp threads and the remaining 54 warp threads, and the beating-up mechanism 3 drives the shuttle 34 to move left and right in the weft direction. After the weft threads pass through each warp thread, the beating-up mechanism 3 moves backward, that is, moves toward the direction of the thread pressing mechanism 5, and pushes the weft threads forward to a predetermined position, and then the beating-up mechanism 3 resets forward. At this time, the palm lifting mechanism 2 continues the second step of palm lifting: the first, third, and fourth palm frame components are lifted, driving the 54 warp threads to lift, and a shed is formed between the 18 warp threads in the second palm frame component 22. At this time, the beating-up mechanism 3 controls the shuttle 34 to pass through the shed, and the weft threads are pushed forward to the predetermined position. After the thread passes through, the beating-up mechanism 3 drives the shuttle 34 to move backward again, pushes the weft thread to the set position, and then the beating-up mechanism 3 resets forward, and the palm lifting mechanism 2 continues to perform the third step of palm lifting: the fourth palm frame assembly 24 is lifted, driving 18 warp threads to be lifted, and a shed is formed between the remaining 54 warp threads, and then the shuttle 34 moves the weft thread to put on the weft thread, and after the shuttle 34 pushes the weft thread backward to the predetermined position, the shuttle 34 resets forward; the palm lifting mechanism 2 continues to perform the fourth step of palm lifting: the second, third, and fourth palm frame assemblies are lifted, driving 54 warp threads to be lifted, and a shed is formed between the remaining 18 warp threads, and the shuttle 34 continues to move in the weft direction to put on the weft thread, and then moves backward to the predetermined position.

[0113] The spacing between two adjacent weft threads is determined by the rotation speed of the active roller 63 of the winding mechanism 6. Each time the beating mechanism 3 pushes the weft thread backward to a predetermined position, the servo motor controlling the rotation of the active roller 63 will slowly reel in the weft thread, driving the woven weft thread to move backward to make room for the next weft thread.

[0114] According to the steps of the beating mechanism 3 and the palm lifting mechanism 2, a cylindrical braided net can be woven, and the narrow-pitch portion 433, the variable-pitch portion 432, and the wide-pitch portion 431 formed on the balloon are controlled by the weft-direction diameter-changing mechanism 4.

[0115] The method for achieving weft diameter change of the balloon-shaped cylindrical net 1 is as follows:

[0116] First, the first steel reed 42 is lifted upward so that each warp thread passes through the narrow-pitch portion 433 of the first steel reed 42. At this time, the small-diameter section 13 of the tubular mesh is being woven. During the weaving process, the first steel reed 42 gradually descends, and each warp thread slowly enters the variable-pitch portion 432 of the first steel reed 42. At this time, the weaving area is the variable-diameter section 12 of the tubular mesh. The first steel reed 42 continues to descend, and each warp thread slowly enters the wide-pitch portion 431 of the first steel reed 42. At this time, the weaving area is the large-diameter section 11 of the tubular mesh. After the large-diameter section 11 is woven, the first steel reed 42 begins to be lifted slowly, and each warp thread enters the variable-pitch portion 432 again. At this time, another variable-diameter section 12 of the tubular mesh is being woven, and finally enters the narrow-pitch portion 433 of the first steel reed 42. At this time, another small-diameter section 13 of the tubular mesh is being woven.

[0117] After weaving a balloon-shaped cylindrical braided net 1, continue to repeat the above steps.

[0118] The balloon-shaped cylindrical net 1 of the present invention uses a weaving machine, which realizes the weaving of the cylindrical net through the palm lifting mechanism 2 + the weft beating mechanism 3, and then uses the weft diameter changing mechanism 4 to control the spacing between each warp thread, so as to weave a narrow spacing portion 433, a variable spacing portion 432 and a wide spacing portion 431 on the cylindrical net, that is, the balloon-shaped cylindrical net 1.
