Description

Technical Field

[0001] This invention relates to a dual-station bamboo curtain weaving machine. Background Technology

[0002] Existing bamboo curtain weaving machines are generally single-station weaving machines, meaning they can only weave one bamboo curtain at a time. After the bamboo curtain is woven, the weaving threads need to be cut and knotted manually. In addition, the pushing of each bamboo strip after weaving and the placement of the bamboo strips after feeding all require manual intervention, resulting in low automation efficiency and low processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly automated dual-station bamboo curtain weaving machine with the advantage of high processing efficiency.

[0004] The technical solution of the present invention is: a double-station bamboo curtain weaving machine, including a frame, wherein the frame is provided with an upper bamboo curtain weaving mechanism, a lower bamboo curtain weaving mechanism and a thread cutting mechanism; Both the upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism include a bracket, a winding mechanism, and a material pushing mechanism. The winding mechanism includes multiple winding frames that are rotatably connected to the frame at equal distances. Each winding frame has two wire outlets at its front end, and braided wires are respectively provided on the two wire outlets. When feeding, the thin bamboo strips pass through the two braided threads of each winding frame and are placed on the bracket. Each winding frame rotates clockwise to make the two braided threads cross and bind the thin bamboo strips. When each winding frame weaves the next thin bamboo strip, it reverses to reset and repeats in this way. The pushing mechanism has multiple sets of pushing plates, each set of pushing plates is set on one side of each winding frame. After each thin bamboo strip is bound by the braided wire, each pushing plate pushes the thin bamboo strip and the braided wire to move forward along the bracket, and the two braided wires on each winding frame are pulled out at the same time. The winding mechanisms of the upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism are linked together, and the pushing mechanisms of the upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism are linked together. The upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism share a common feeding mechanism; The feeding mechanism includes a box fixed to one side of the frame. The box is open on both sides. A blade is provided in the middle of the box. A feeding wheel assembly is provided in the box on the feeding side. A first guide wheel assembly is provided in the box on the discharging side. A guide groove is also provided between the box and the two brackets. The thick bamboo strips are fed to the blade to be split into two thin bamboo strips and output to the two brackets respectively. The wire cutting mechanism includes a bracket and multiple sets of wire cutting blades mounted on the bracket. The bracket is vertically connected to the top of the machine frame. Each set of wire cutting blades is vertically mounted to the front end of each winding frame. A knotting mechanism is provided on the bracket on both sides of each wire cutting blade. The knotting mechanism includes a housing, a through hole in the middle of the housing for the braiding thread to pass through, a V-shaped groove at the lower end of the housing that connects to the through hole, and an air blowing channel on one side of the housing, with the air outlet of the air blowing channel located above or below the axis of the through hole. During the thread cutting process, the support lowers, allowing the braided threads between the thin bamboo strip and the winding frame to enter the through holes along the V-shaped grooves. Then, the support rises, loosening the braided threads that were taut between the thin bamboo strip and the winding frame, but still retaining them within the through holes of the housing. Air intake through the input channel causes the braided threads to tumble and rotate along the inner walls of their corresponding through holes under the influence of airflow. During rotation, two braided threads in the same group become loose and frayed due to friction, eventually tangling together. Then, the thread cutter cuts the braided threads between the two knotting mechanisms, resulting in knotted thread ends at the ends of the woven bamboo curtain and the two outlet ends of the winding frame.

[0005] Specifically, the wire cutter is a pneumatic scissor.

[0006] Optionally, each of the through holes has a rough inner wall, or each of the through holes is densely covered with fine, hair-like teeth, or each of the through holes is densely covered with fine, hair-like needles.

[0007] Furthermore, an air intake is provided on the top of the housing.

[0008] Furthermore, the bracket is provided with a mounting bracket corresponding to the winding frame, and the rear end of the winding frame is provided with a hollow shaft connecting the two wire outlets. A transmission gear is fixed at the rear end of the hollow shaft. The bracket is also reciprocally connected with racks corresponding to the winding frames of the upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism, respectively. Each transmission gear meshes with two racks, and the two racks are connected to the piston rod of the same cylinder through a connecting bracket.

[0009] Furthermore, the pushing mechanism includes a connecting shaft and inverted "L"-shaped pushing plates fixed at equal intervals on the connecting shaft. The connecting shaft is rotatably connected to the frame via a bracket. A drive shaft is rotatably connected to the lower end of the frame. One end of the drive shaft is connected to the ends of the connecting shafts on the upper and lower bamboo curtain weaving mechanisms via a synchronous belt. A connecting arm is connected to the middle of the drive shaft via a connector. The lower end of the connecting arm is rotatably connected to an eccentric disk. The eccentric disk is rotatably connected to the frame via a shaft. The shaft is connected to the output shaft of a servo motor via a reduction gear set.

[0010] Furthermore, the bracket is composed of multiple trays fixed at equal intervals on the frame, and each tray is also provided with a pressure plate above it.

[0011] Furthermore, a second set of guide wheels is also provided on the frame between the two guide troughs and the two brackets.

[0012] Furthermore, the rear end of the frame is also provided with a wire storage rack and a guide wheel. The wire storage rack is provided with a braided spool. The braided wire is led out from the braided spool, then fed into the hollow shaft of the winding rack via the guide wheel, and then output from the outlet.

[0013] Furthermore, an air storage tank is provided at the lower end of the frame. One end of the air storage tank is connected to an air pump, and the other end of the air storage tank is connected to the air blowing channel on each housing through a connecting pipe. A solenoid valve is also provided on the connecting pipe, and the air intake is connected to a negative pressure air pump through the connecting pipe.

[0014] The advantages of this invention are: simple structure, the upper bamboo curtain weaving mechanism and the lower bamboo curtain weaving mechanism can weave bamboo curtains simultaneously, and high processing efficiency; The winding mechanism and pushing mechanism of the upper and lower bamboo curtain weaving mechanism are linked by the same drive mechanism and fed by the same feeding mechanism. The weaving progress is consistent, and the arrangement of the drive mechanism is also saved, which can save manufacturing costs. The thread-cutting mechanism, through lifting and lowering, can sequentially cut the weaving threads on the upper and lower bamboo curtain weaving mechanisms after the bamboo curtain is woven; The thread-cutting mechanism is also equipped with a knotting mechanism. The airflow blows the two braided threads to roll and rotate in the through hole. During the rotation, the two braided threads become loose and frayed due to friction, and eventually become entangled and combined into one. Then the thread-cutting knife cuts the braided thread between the two knotting mechanisms. The ends of the woven bamboo curtain and the two ends of the winding frame are respectively obtained with knotted thread ends. No manual knotting is required afterward, which can further improve the processing efficiency. Among them, the connecting shaft of the two pushing mechanisms achieves intermittent synchronous oscillation through a synchronous belt, drive shaft and servo motor, with precise oscillation frequency and easier control; The feeding mechanism splits a thick bamboo strip into two thin bamboo strips, which are then fed onto the brackets of the upper and lower bamboo curtain weaving mechanisms, saving time in the early preparation of materials.

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Combination Figure 1-6 As shown, a dual-station bamboo curtain weaving machine includes a frame, on which an upper bamboo curtain weaving mechanism 1, a lower bamboo curtain weaving mechanism 2, and a thread cutting mechanism 3 are provided; Both the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 include a bracket 4, a winding mechanism, and a material pushing mechanism. The winding mechanism includes multiple winding frames 5 that are rotatably connected to the frame at equal distances. Each winding frame 5 has two wire outlets 6 at its front end, and braided wires 7 are respectively provided on the two wire outlets 6. During feeding, the thin bamboo strip 8 passes through the two braided wires 7 of each winding frame 5 and is placed on the bracket 4. Each winding frame 5 rotates 180° or 360° to make the two braided wires 7 cross and bind the thin bamboo strip 8. When each winding frame 5 weaves the next thin bamboo strip 8, it rotates in the opposite direction to reset and repeats in this way to avoid the two braided wires 7 entering the winding mechanism from being over-wound behind the winding mechanism. The pushing mechanism has multiple sets of pushing plates 9, each set of pushing plates 9 is respectively set on one side of each winding frame 5. After each thin bamboo strip 8 is bound by the braided wire 7, each pushing plate 9 pushes the thin bamboo strip 8 together with the braided wire 7 to move forward along the bracket 4. Thus, after the thin bamboo strip 8 is pushed forward, the two braided wires 7 on each winding frame 5 are also pulled out at the same time, still forming an acute angle shape between the thin bamboo strip 8 and the two wire outlets 6, so as to facilitate the passage of the next thin bamboo strip 8. The winding mechanisms of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 are linked together, and the pushing mechanisms of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 are linked together. The upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 share a feeding mechanism 10; The feeding mechanism 10 includes a box 11 fixed to one side of the frame. The box 11 is open on both sides. A blade 12 is provided in the middle of the box 11. A feeding wheel set 13 is provided in the box 11 on the feeding side. A first guide wheel set 14 is provided in the box 11 on the discharging side. A guide groove 15 is also provided between the box 11 and the brackets 4 of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2. The thick bamboo strips 16 are fed by the feeding wheel set 13 to the blade 12 and split into two thin bamboo strips 8. The two thin bamboo strips 8 are then guided by the first guide wheel set 14 and the two guide grooves 15 and fed to the brackets 4 of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 respectively. The wire cutting mechanism 3 includes a bracket 17 and multiple sets of wire cutting blades 18 mounted on the bracket 17. The bracket 17 is vertically connected to the top of the frame. Each set of wire cutting blades 18 is vertically mounted to the front end of each winding frame 5. A knotting mechanism is provided on the bracket 17 on both sides of each wire cutting blade 18. The knotting mechanism includes a housing 19, a through hole 20 in the middle of the housing 19 for the braided thread 7 to pass through, a V-shaped groove 21 at the lower end of the housing 19 communicating with the through hole 20, and an air blowing channel 22 on one side of the housing 19, with the air outlet of the air blowing channel 22 located above or below the axis of the through hole 20. When cutting the thread, the bracket 17 lowers so that each group of braided thread 7 located between the thin bamboo strip 8 and the winding frame 5 enters the through hole 20 along the V-shaped groove 21. Then the bracket 17 rises back, so that each group of braided thread 7 tightly stretched between the thin bamboo strip 8 and the winding frame 5 is relaxed but still stuck in the through hole 20 of the housing 19. Air is introduced through the input channel, so that each group of braided thread 7 rolls and rotates along the inner wall of the corresponding through hole 20 under the action of airflow. During the rotation, two braided threads 7 in the same group become loose and frayed due to friction, and finally become entangled and combined into one. Then the thread cutter 18 cuts the braided thread 7 between the two knotting mechanisms, and the ends of the woven bamboo curtain and the two outlets 6 of the winding frame 5 are respectively obtained with knotted thread ends.

[0019] Specifically, the wire cutter 18 is a pneumatic scissor. The two V-shaped blades in the pneumatic scissor can smoothly cut the braided thread 7 that is in a slightly drooping state between the two knotting mechanisms. At the same time, the V-shaped blades also serve as guides. Together with the V-shaped grooves 21 at the lower end of the two knotting structures, they can prevent the braided thread 7 from being located outside the wire cutter 18 and thus unable to be cut initially.

[0020] In another embodiment, such as Figure 3 As shown, each of the through holes 20 on the housing 19 has a rough inner wall, or each through hole 20 is densely covered with fine teeth for raising hair, or each through hole 20 is densely covered with small needles for raising hair, so that the two braided threads 7 in the through hole 20 can quickly raise hair during the tumbling and rotating process, which is conducive to the two braided threads 7 quickly entangled and combined into one.

[0021] In another embodiment, combined Figure 3 and Figure 5 As shown, the top of the housing 19 is also provided with an air intake 23 to draw up the braided thread 7 hanging in the V-shaped groove 21 into the through hole 20.

[0022] In another embodiment, combined Figure 1 and Figure 2 As shown, the bracket 17 is provided with a mounting bracket 24 corresponding to the winding frame 5. The rear end of the winding frame 5 is provided with a hollow shaft connecting the two outlet ports 6. The rear end of the hollow shaft is fixed with a transmission gear 25. The bracket 17 is also reciprocally connected with racks 26 corresponding to the winding frames 5 on the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2, respectively. Each transmission gear 25 meshes with two racks 26. The two racks 26 are connected to the piston rod of the same cylinder through a connecting bracket. The extension and retraction of the piston rod of the cylinder drives the two racks 26 to extend and retract simultaneously. The two racks 26 simultaneously drive each winding frame 5 to rotate in both directions.

[0023] In another embodiment, combined Figure 1 and Figure 2 As shown, the pushing mechanism includes a connecting shaft 27 and inverted "L"-shaped pushing plates 9 fixed at equal intervals on the connecting shaft 27. The connecting shaft 27 is rotatably connected to the frame via a bracket 17. A drive shaft 28 is rotatably connected to the lower end of the frame. One end of the drive shaft 28 is connected to the ends of the connecting shafts 27 on the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 via a synchronous belt. A connecting arm is connected to the middle of the drive shaft 28 via a connector. The lower end of the connecting arm is rotatably connected to an eccentric disk 29. The eccentric disk 29 is rotatably connected to the frame via a shaft. The shaft is connected to the output shaft of a servo motor via a reduction gear set. The servo motor drives the eccentric disk 29 to rotate intermittently. The eccentric disk 29 drives the drive shaft 28 to swing intermittently by 90° via the connecting arm belt. The drive shaft 28 drives the two connecting shafts 27 to swing synchronously, thereby driving each pushing plate 9 to swing intermittently by 90°, so as to simultaneously push the thin bamboo strips 8 that have been wrapped and bound on the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 forward.

[0024] In another embodiment, combined Figure 1 and Figure 2 As shown, the bracket 4 is composed of multiple trays fixed at equal intervals on the frame. Each tray is also provided with a pressure plate 30 above it to limit the thin bamboo strip 8 between the tray and the pressure plate 30, so as to prevent the thin bamboo strip 8 from flipping when it is pushed forward.

[0025] In another embodiment, such as Figure 6 As shown, the two guide troughs 15 and the two brackets 4 are respectively provided with a second guide wheel group 31 to guide the two broken thin bamboo strips 8 to the corresponding brackets 4.

[0026] In another embodiment, the rear end of the frame is also provided with a wire storage rack and a guide wheel. The wire storage rack is provided with a braided spool. The braided wire 7 is led out from the braided spool, then fed into the hollow shaft of the winding frame 5 via the guide wheel, and then output from the outlet 6.

[0027] In another embodiment, the lower end of the frame is also provided with an air tank 32. One end of the air tank 32 is connected to an air pump, and the other end of the air tank 32 is connected to the air blowing channel 22 on each housing 19 through a connecting pipe. The connecting pipe is also provided with a solenoid valve, and the air intake 23 is connected to a negative pressure air pump through a connecting pipe. In the above structure, the gas storage tank 32 is used to temporarily store the gas output by the air pump, so that the airflow to the blowing channel 22 is more stable, and thus the knotting of the winding thread is more efficient.

[0028] The working principle of this invention is as follows: Thick bamboo strips 16 are fed one by one from the feeding side of the feeding mechanism 10. Under the drive of the feeding wheel group 13, they are split into two thin bamboo strips 8 by the blade 12. The two thin bamboo strips 8 are fed to the brackets 4 of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 respectively through the first guide wheel group 14, the guide groove and the second guide wheel group 31. At this time, a thin bamboo strip 8 is preset in the bracket 4 of the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving mechanism 2 respectively. The ends of the two weaving lines 7 on each winding frame 5 are pre-wound and bound to the thin bamboo strip 8. Therefore, under the pulling action of the preset thin bamboo strip 8, the two weaving lines 7 on each winding frame 5 cross at an acute angle. The newly input thin bamboo strip 8 passes through the two weaving lines 7 on each corresponding winding frame 5. Afterwards, each winding frame 5 rotates 180° or 360° to make the two braided threads 7 cross and bind the thin bamboo strips 8. The pusher plate 9 of the pusher mechanism flips up 90° and then resets, pushing the thin bamboo strips 8 bound by the braided threads 7 forward. The braided threads 7 on each winding frame 5 are then pulled out. The newly input thin bamboo strips 8 still pass through the two braided threads 7 on the corresponding winding frame 5 and are placed on the bracket 4. Each winding frame 5 rotates 180° or 360° in the opposite direction to reset and bind the thin bamboo strips 8. Thus, the upper bamboo curtain weaving mechanism 1 and the lower bamboo curtain weaving machine simultaneously perform rapid dual-station bamboo curtain weaving. After the bamboo curtain is woven to the preset length, the upper bamboo curtain weaving mechanism 1, the lower bamboo curtain weaving mechanism 2 and the feeding mechanism 10 stop working, and the thread cutting mechanism 3 descends. The thread-cutting mechanism 3 first cuts the weaving thread 7 on the upper bamboo curtain weaving mechanism 1; The bracket 17 is lowered so that the braided threads 7 located between the thin bamboo strip 8 and the winding frame 5 enter the through hole 20 along the V-shaped groove 21. Then the bracket 17 is raised so that the braided threads 7 taut between the thin bamboo strip 8 and the winding frame 5 are loosened but still stuck in the through hole 20 of the housing 19. (If necessary, the air intake 23 is activated to draw air in so that the braided threads 7 that have come out of the through hole 20 are drawn back into the through hole 20.) Then air is introduced into the input channel so that the braided threads 7 tumble and rotate along the inner wall of the corresponding through hole 20 under the action of airflow. During the rotation, the two braided threads 7 in the same group become loose and frayed due to friction, and finally become entangled and combined into one. Then the wire cutter 18 cuts the braided threads 7 between the two knotting mechanisms. The ends of the woven bamboo curtain and the ends of the two wire outlets 6 of the winding frame 5 are respectively obtained with knotted thread ends. After the weaving thread 7 of the upper bamboo curtain weaving mechanism 1 is cut, the support 17 continues to descend and repeats the above operation to cut the weaving thread 7 of the lower bamboo curtain weaving mechanism 2.
