Description

Technical Field

[0001] The present invention relates to the technical field of braiding machines, in particular to a braiding machine capable of preventing braiding wrinkles. Background Art

[0002] A knitting machine is a mechanical device used to process yarn, thread, rope and other materials into fabrics, meshes or other woven products with certain structures and functions by interweaving, crocheting or knitting.

[0003] During the production process of the braiding machine, the problem of hose wrinkles often occurs, which not only affects the appearance quality of the hose, but may also affect its performance, such as reducing the pressure resistance, wear resistance or stability of the hose. During the braiding process, the hose is released from the pay-off wheel, braided by the braiding machine, and then collected by the take-up wheel. If the pay-off wheel cannot adjust the release length of the hose according to the pulling speed of the take-up wheel, or the hose lacks effective tension buffering and guiding mechanism during transportation, the hose may form unnecessary bends or wrinkles inside or outside the braiding machine. Once these wrinkles are formed, it is difficult to completely eliminate them during subsequent processing or use, thereby affecting the overall quality of the hose. Therefore, a braiding machine that prevents braiding wrinkles is needed. Summary of the Invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] Example 1, as Figure 1 and Figure 2 As shown, a braiding machine for preventing braiding wrinkles includes a double-row bracket 8 and a hose 7. A braiding machine body 2 for braiding the hose 7 is provided on the top frame of the double-row bracket 8, a pay-off wheel 1 for releasing the hose 7 is provided on the left side of the braiding machine body 2, and a take-up wheel 3 for collecting the hose 7 is provided on the right side of the braiding machine body 2. A transmission device 4 for clamping the hose 7 is provided on the bottom frame of the double-row bracket 8, a leak detection device 5 for guiding and detecting the hose 7 is provided in the middle of the bottom frame of the double-row bracket 8, and a tension buffer mechanism 6 for stretching the hose 7 is provided on the surface of the braiding machine body 2 facing the double-row bracket 8.

[0031] This device is used to braid the hose 7. Its braiding machine body 2 is a device specially used for producing the hose braid layer. Its core function is to braid yarn, steel wire, fiber and other materials into the outer layer of the hose 7 through a specific braiding process to enhance the strength, pressure resistance, wear resistance or stability of the hose 7. Its working principle is mainly based on the movement of the braiding mechanism. A plurality of spindles (carrying braiding materials) move around the hose 7 blank along a specific trajectory, so that the materials are interwoven to form a braided layer. Its braiding machine body 2 can be replaced by a vertical braiding machine of model 36L-114BI in the prior art.

[0032] In the above description, a three-phase asynchronous motor is installed on the pay-off wheel 1, which can use a three-phase asynchronous AC motor of the existing technology model: YE380M-2.

[0033] This case uses 380V three-phase AC for power supply.

[0034] Before implementing this device, first:

[0035] Place the pay-off wheel 1 equipped with the hose 7 on the left side of the braiding machine body 2, then pass a portion of the hose 7 on the pay-off wheel 1 through the transmission device 4, the leak detection device 5 and the tension buffer mechanism 6 and connect it to the braiding machine body 2, then wind the hose 7 around the turntable on the braiding machine body 2, after winding it twice, connect the hose 7 to the take-up wheel 3, so that the take-up wheel 3 collects the braided hose 7;

[0036] After the preparatory work is completed, the staff starts the take-up wheel 3 and the braiding machine body 2 to move. When the take-up wheel 3 moves, it will pull the hose 7 wrapped around the pay-off wheel 1. When the braiding machine body 2 moves, the braiding wire is wound around the hose 7 emerging from the braiding machine body 2 through the spindle equipped with the braiding wire, thereby weaving the hose.

[0037] When this case is implemented, there are two working states. State 1: when the device is working normally, the hose 7 will pass through the transmission device 4, the leak detection device 5 and the tension buffer mechanism 6, and then enter the braiding machine body 2. The spindle on the rear braiding machine body 2 will wind the braided wire around the hose 7, and the take-up wheel 3 will collect the braided hose 7. The take-up wheel 3 will pull the hose 7 to move. At this time, the pay-off wheel 1 will not always pay out the hose 7. On the way of the take-up wheel 3 pulling the hose 7, because the hose 7 is not always paid out by the pay-off wheel 1, the part of the hose 7 between the pay-off wheel 1 and the braiding machine body 2 will be pulled by the take-up wheel 3 and straightened, so that the hose 7 between the pay-off wheel 1 and the braiding machine body 2 will be in a state of oblique straightening under the influence of the transmission device 4 and the leak detection device 5. When the part of the hose 7 between the pay-off wheel 1 and the braiding machine body 2 is straightened, the transmission device 4 will be lifted, and the transmission device After the cam 1 is swung to the left, the hose 7 is pulled out of the way and the thread is finally woven, so that the cam 1 is swung to the right, and the thread is finally woven, so that the cam 1 is swung to the left, and the thread is finally woven, so that the thread is finally woven, so that the thread is woven, and the thread is finally woven, so that the thread is woven, so that the thread is finally woven, so that the thread is woven, and the thread is finally woven, so that the thread is woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven, so that the thread is finally woven,

[0038] In the above, the leak detection device 5 can guide the hose 7 and deliver the hose 7 into the braiding machine body 2. The leak detection device 5 can also detect the delivered hose 7 to detect whether there are defects such as cracks and scratches on the surface of the hose 7 to ensure that the hose 7 delivered to the braiding machine body 2 is free of defects.

[0039] In the above, the tension buffer mechanism 6 can expand the hose 7 so that the hose 7 will not be folded or indented before entering the braiding machine body 2, ensuring that the hose 7 is fully expanded and enters the braiding machine body 2 for braiding, so that the braided hose 7 will not be wrinkled.

[0040] State 2: During the transportation of the hose 7, if the leak detection device 5 detects damage on the outer surface of the hose 7, the leak detection device 5 will send a message, which will then be transmitted to the transmission device 4, the braiding machine body 2 and the take-up wheel 3. The model 36L-114BI has a self-locking function. When the braiding machine body 2 receives the message, the driving element on the braiding machine body 2 will stop driving;

[0041] After receiving the information, the transmission device 4 will immediately clamp the hose 7 passing through it, so that the hose 7 stops being transported. After receiving the information, the take-up wheel 3 will stop rotating and cancel the material collection of the take-up wheel 3. The braiding machine body 2 and the take-up wheel 3 will slowly stop in the process of stopping movement. There is a buffer time in the middle. When the transmission device 4 clamps and fixes the hose 7, the hose 7 on the pay-off wheel 1 will no longer transport the hose 7. At this time, the take-up wheel 3 will still pull the hose 7 during the buffer time. At this time, the hose 7 wrapped around the tension buffer mechanism 6 will pull the tension buffer mechanism 6 to shrink, so that the tension buffer mechanism 6 releases the wound hose 7, so that the take-up wheel 3 pulls the hose 7 released from the tension buffer mechanism 6, which is used to buffer the take-up wheel 3 and the braiding machine body 2, so that when the take-up wheel 3 stops rotating and buffering, the transmission device 4 catches the hose 7 The take-up wheel 3 can pull the hose 7 on the tension buffer mechanism 6 for buffering, so that the hose 7 released by the tension buffer mechanism 6 can be woven during the buffering process of the braiding machine body 2, and the leak detection device 5 detects the defective part on the hose 7 and remains motionless. The braiding machine body 2 will sound an alarm during the process of stopping movement, reminding the staff that there is a defect in the hose 7 at the leak detection device 5, which needs to be repaired in time. After the repair is completed, the transmission device 4 will release the capture of the hose 7, and then start the take-up wheel 3, the braiding machine body 2 and the pay-off wheel 1 in sequence to work, so that the pay-off wheel 1 releases part of the hose 7 first. At this time, the tension buffer mechanism 6 will expand outward to its original state, stretching the hose 7 delivered to the braiding machine body 2, so that the hose 7 can be leak-checked when the braiding machine body 2 is weaving the hose 7, thereby ensuring the integrity of the hose 7.

[0042] In the above, the take-up wheel 3 is composed of a winding wheel, a three-phase asynchronous motor, a wiring mechanism and an iron frame. The winding wheel is installed on the iron frame, the three-phase asynchronous motor is connected to the winding wheel, and the wiring mechanism is installed on the upper left side of the iron frame. It is used to evenly arrange the braided hose 7 on the winding wheel. The three-phase asynchronous motor is used to drive the winding wheel to rotate, so that the winding wheel pulls the hose 7;

[0043] The take-up wheel 3 can be replaced by a prior art model: XL / DJP330 take-up wheel 3.

[0044] In the second embodiment, further, in order to realize the purpose of driving the three-phase asynchronous motor on the pay-off wheel 1 to move and capture the hose 7, refer to Figure 3 The transmission device 4 includes two fixed plates 41, which are located on the bottom frame of the double-row bracket 8. A cylindrical guide rod 43 is provided on the front and rear sides of the two fixed plates 41. A slide 44 for limiting the hose 7 is provided on the lower and middle parts of the outer surfaces of the two guide rods 43. A rotating rod 45 is provided on the opposite surfaces of the two slides 44. A pressure sensor 42 for controlling the pay-off wheel 1 is provided under the upper fixed plate 41. A catching mechanism 48 for catching the hose 7 is provided on the right side of the two slides 44. A buffer spring 47 sleeved on the two guide rods 43 is installed on the lower fixed plate 41. A circular plate 46 is provided on the two buffer springs 47.

[0045] Furthermore, the two circular plates 46 slide with the outer surfaces of the two guide rods 43;

[0046] Furthermore, the catching mechanism 48 includes an annular shell 481, which is arranged on the right side of the two slides 44. The middle part of the annular shell 481 is hollow, and the outer ring of the annular shell 481 is provided with a gear ring 482. The inner wall of the annular shell 481 is provided with three spur gears 485. The surface of the annular shell 481 is provided with three sliding frames 484 that slide relatively. The three sliding frames 484 are each provided with a rack 483 that meshes with the three spur gears 485. The three sliding frames 484 are each provided with a clamping plate 486 for clamping the hose 7. The lower sliding frame 484 is provided with an electric telescopic cylinder 487 for driving on the side facing the bottom frame of the double-row bracket 8.

[0047] Furthermore, the electric telescopic cylinder 487 is installed on the slide plate 44 at the bottom, and the three spur gears 485 are all engaged with the ring gear 482, so that the ring gear 482 transmits the rack 483 through the three spur gears 485.

[0048] In the above description, the hose 7 passes between the two rotating rods 45 and the catch mechanism 48 .

[0049] In the above description, when the hose 7 is in a relaxed state, the slide plate 44 and the rotating rod 45 are at the lower part of the guide rod 43. When the hose 7 is straightened, the hose 7 drives the slide plate 44 to slide upward on the outer surface of the guide rod 43. At this time, the rotating rod 45 and the capture mechanism 48 move upward together. When the upper slide plate 44 contacts the pressure sensor 42, the pressure sensor 42 receives a signal and transmits the information to the three-phase asynchronous motor on the pay-off wheel 1, causing the three-phase asynchronous motor to rotate, and driving the pay-off wheel 1 to rotate clockwise through the coupling, releasing a part of the hose 7, and then stopping rotation. At this time, the slide plate 44, the rotating rod 45 and the capture mechanism 48 will slide downward on the surface of the guide rod 43 under the influence of gravity.

[0050] In the above description, when the rotating rod 45 moves upward, the buffer spring 47 releases the pressure and pushes the circular plate 46 to slide upward on the surface of the guide rod 43. When the slide plate 44 moves downward, the circular plate 46 buffers the slide plate 44 through the buffer spring 47, so that the slide plate 44 will not directly hit the lower fixed plate 41, thereby ensuring the integrity of the slide plate 44.

[0051] In the above, the pressure sensor 42 adopts the existing technology model: ZY-2C pressure sensor 42, and the pressure sensor 42 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals or other required forms of information according to a certain rule.

[0052] In the above description, when the leak detection device 5 detects damage on the surface of the hose 7, it transmits the information to the electric telescopic cylinder 487, causing the electric telescopic cylinder 487 to move and extend the output end;

[0053] In the above, the annular shell 481 is fixedly mounted on the two slides 44. When the output end of the electric telescopic cylinder 487 is extended, it pushes the slide frame 484 at the lower portion to slide in the annular shell 481, so that the slide frame 484 at the lower portion drives the connected rack 483 to move. At this time, the rack 483 is meshed with the spur gear 485, so that when the lower rack 483 moves upward, it drives the spur gear 485 at the same position to rotate on the left wall of the annular shell 481. When the lower spur gear 485 rotates, it meshes with the ring gear 482. , it will drive the ring gear 482 to rotate on the inner surface of the annular shell 481. When the ring gear 482 rotates, it will drive the other two spur gears 485 to rotate. The spur gear 485 then drives the rack 483 at the same location to drive the other two slide frames 484 to move toward a part close to the axis of the annular shell 481. When the three slide frames 484 move, they will drive the three fixedly connected splints 486 to also move toward the axis of the annular shell 481, so that the three splints 486 clamp and fix the hose 7 to achieve capture.

[0054] In the above description, the surfaces of the three clamping plates 486 are provided with anti-slip strips, which increase the stability of clamping with the outer surface of the hose 7.

[0055] In the above description, the electric telescopic cylinder 487 adopts the existing technology model: LH-AUTO servo electric cylinder.

[0056] Further, in order to achieve the purpose of guiding and detecting the hose 7 by the leak detection device 5, refer to Figure 7 The leak detection device 5 includes a rotating frame 57, which is installed on the bottom frame of the double-row bracket 8. The rotating frame 57 is provided with a guide wheel 56 for guiding the hose 7. The front and rear sides of the rotating frame 57 are both provided with a fixing rod 51 for installation. The two fixing rods 51 are commonly provided with a mounting frame 52. The mounting frame 52 is provided with a diffuser lamp 53 for illuminating the hose 7. Two industrial cameras 58 are provided on the right side of the mounting frame 52. The front and rear sides of the right side of the mounting frame 52 are both provided with a fixing mechanism 54 for clamping and fixing the industrial camera 58. A reflector 55 for reflecting the light of the diffuser lamp 53 is commonly provided between the two industrial cameras 58.

[0057] Furthermore, the diffuser lamp 53 is irradiated in a downwardly tilted state;

[0058] Furthermore, the fixing mechanism 54 includes an L-shaped plate 541, which is installed on the vertical surface of the right side of the mounting frame 52. A bidirectional threaded rod 542 is provided on the side of the L-shaped plate 541 parallel to the vertical surface on the right side of the mounting frame 52. A knob 543 for driving the bidirectional threaded rod 542 to rotate is provided on the right side of the L-shaped plate 541. A clamping plate 544 for clamping the industrial camera 58 is provided on both the left and right sides of the bidirectional threaded rod 542.

[0059] In the above description, the hose 7 passes through the lower portion of the guide wheel 56 and is connected upward from the right portion.

[0060] In the above, before the staff starts the movement of the device, they first place the industrial camera 58 between the two clamps 544, and then the staff manually rotates the knob 543 to rotate the knob 543. When the knob 543 rotates, through the relationship of the threaded connection with the two bidirectional threaded rods 542 and the design of the bidirectional thread, the two clamps 544 will be driven to move closer to each other, clamping and fixing the industrial camera 58, so that the industrial camera 58 can detect the hose 7.

[0061] In the above, during the inspection, the astigmatism lamp 53 needs to be turned on so that the astigmatism lamp 53 illuminates the area around the hose 7. The reflector 55 designed therein will reflect the light emitted by the astigmatism lamp 53 so that the hose 7 away from the astigmatism lamp 53 will not leak light. The hose 7 is then inspected for leaks through two industrial cameras 58. When a defect is detected in the part of the hose 7 between the two industrial cameras 58, the industrial camera 58 will transmit the information to the capture mechanism 48, the braiding machine body 2 and the take-up wheel 3, so that the capture mechanism 48 captures the hose 7, the braiding machine body 2 and the take-up wheel 3 stop working, and then the braiding machine body 2 issues an alarm, allowing the staff to repair the hose 7.

[0062] In the above description, the mounting bracket 52 is mounted on the two fixing rods 51 by means of bolts.

[0063] In the above, the industrial camera 58 adopts the existing technology model: IK033C-70 industrial camera 58. The industrial camera 58 is clamped and fixed by the fixing mechanism 54, so that the industrial camera 58 is easy to remove by the staff when it needs to be repaired.

[0064] Further, in order to realize the purpose of tension buffer mechanism 6 stretching hose 7 and temporarily storing a portion of hose 7 to buffer braiding machine body 2 and take-up wheel 3, refer to Figure 9 The tension buffer mechanism 6 includes two support plates 61, which are respectively installed on the support legs of the double-row bracket 8. Rectangular frames 62 are provided on the opposite surfaces of the two support plates 61. Sliding rods 65 are provided in the two rectangular frames 62. The opposite surfaces of the two sliding rods 65 are provided with movable pulleys 63 for stretching the hose 7. The two sliding rods 65 are provided with tension springs 66 that apply tension to the sliding rods 65 on one side close to the support plate 61 on the same side. Two fixed pulleys 64 for guiding the hose 7 are provided under the braiding machine body 2, and the two fixed pulleys 64 are staggered.

[0065] In the above description, the hose 7 passes through the lower fixed pulley 64, then passes through the right movable pulley 63 to the left movable pulley 63, then passes from the left movable pulley 63 to the upper fixed pulley 64, and finally passes from the upper fixed pulley 64 into the braiding machine body 2.

[0066] In the above, the design of the tension spring 66 can pull the sliding rod 65 at the same position, so that the sliding rod 65 stretches the hose 7 through the movable pulley 63, so that the hose 7 remains flat.

[0067] In the above description, the two fixed pulleys 64 are used to guide the hose 7 .

[0068] In the above, when the leak detection device 5 detects a defect on the outer surface of the hose 7, the capture mechanism 48 will capture the hose 7, and the braiding machine body 2 and the take-up wheel 3 will stop working. After the capture mechanism 48 captures the hose 7, the hose 7 will no longer be transported from the pay-off wheel 1 to the braiding machine body 2. At this time, the take-up wheel 3 will have a buffer time before stopping working. The take-up wheel 3 will still pull the hose 7. At this time, the hose 7 wrapped around the two movable pulleys 63 will be subjected to the pulling force of the take-up wheel 3 and the reaction force of the capture mechanism 48. , which will cause the two movable pulleys 63 to move toward a portion closer to each other. When the two movable pulleys 63 move, they will pull the two sliding rods 65 to slide in the inner cavity of the rectangular frame 62, and stretch the tension spring 66 to generate pressure. When the two movable pulleys 63 move toward a portion closer to each other, a portion of the wound hose 7 is released, causing the take-up wheel 3 to pull the released hose 7, thereby pulling a portion of the hose 7 when buffering the take-up wheel 3, so that the hose 7 will not be pulled by the take-up wheel 3 and the capture mechanism 48, thereby ensuring that the hose 7 will not be damaged.
