DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] Example 1: Reference Figures 1-16 , an auxiliary beating structure for an acupuncture device, comprising: a mounting plate 1, a baffle 2, a baffle second 3, a connecting rod 4, a beating piece 5 and a quick-change needle row 6, the mounting plate 1 is rotatably connected to the top surface of the quick-change needle row 6, a plurality of connecting rods 4 are connected to the mounting plate 1, the connecting rod 4 is connected to one end surface of the beating piece 5, the top surface of the quick-change needle row 6 is connected with the baffle 2 and the baffle second 3, the two sides of the mounting plate 1 are respectively in contact with the baffle 2 and the baffle second 3, and the other end surface of the beating piece 5 is set toward the tip of the needle at the end of the quick-change needle row 6.

[0037] The principles of the above scheme are:

[0038] After the device is started, the needles at the ends of the quick-change needle row 6 repeatedly needle the preform. After needle-puncturing one area of ​​the preform, the quick-change needle row 6 and the needles move synchronously to the unpunctured part of the preform for needle-puncturing. While the needles are working, they drive the mounting plate 1 to move synchronously. The mounting plate 1 drives the connecting rod 4 and the beating plate 5 to move synchronously. The beating plate 5 beats and compacts the area that has been needled.

[0039] One side of the mounting plate 1 contacts and cooperates with the end of the baffle 2 , and one side of the mounting plate 1 contacts and cooperates with the end of the baffle 2 3 , so the baffle 2 and the baffle 2 3 can limit the mounting plate 1 .

[0040] The beneficial effects of the above scheme are:

[0041] After the preform is compacted by the beating piece 5, the yarn bulging on the surface of the preform can be pushed in one direction by the yarn chasing rod, so as to ensure that the surface after acupuncture will not be bulged and more compact, and finally improve the quality of the preform after acupuncture;

[0042] The device does not require an external driving device when working, and works synchronously with the quick-change needle bar 6. Therefore, the device is simple to manufacture and the cost of manufacturing the device is greatly saved.

[0043] Example 2: Reference Figures 1-16 The other end of the quick-change needle row 6 is connected to the end row of the connecting rod 2 7, the other end of the connecting rod 2 7 is connected to a needle bearing 8, an eccentric wheel 9 is inserted into the needle bearing 8, and a rotating shaft 10 is connected to the eccentric socket 11 of the eccentric wheel 9, and the end of the rotating shaft 10 is connected to the output end of the motor 12.

[0044] The motor 12 is connected to the top of the bottom plate 13 , and the bottom plate 13 is slidably connected to the quick-change needle row 6 .

[0045] The principles and beneficial effects of the above scheme are:

[0046] The reciprocating motion of the needles on the quick-change needle array 6 is implemented by an eccentric mechanism. When the mechanism is working, after the motor 12 is started, its output end drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the eccentric wheel 9 to rotate through the eccentric socket 11. Under the sliding cooperation between the bottom plate 13 and the quick-change needle array 6, the eccentric wheel 9 drives the connecting rod 2 7 to reciprocate through the needle bearing 8, and then drives the quick-change needle array 6 to reciprocate through the connecting rod 2 7. The quick-change needle array 6 finally drives the flapping piece 5 to reciprocate synchronously, avoiding the setting of the driving component of the flapping piece 5;

[0047] The eccentric socket 11 of the eccentric wheel 9 is connected to the rotating shaft 10, which simplifies the complexity of the eccentric mechanism. The uniform rotation of the rotating shaft 10 is converted into the variable speed linear reciprocating motion of the beating plate 5. When the beating plate 5 moves to the preform, it can apply sufficient pressure to the preform to ensure the quality of the preform after acupuncture.

[0048] Example 3: Reference Figures 1-16 The bottom of the base plate 13 is connected to the top of the sliding plate 14 in the horizontal moving member 15, the bottom of the sliding plate 14 is threadedly connected to the screw 16, the screw 16 is rotatably connected to the mounting plate 2 17, the mounting plate 2 17 is slidably connected to the bottom of the sliding plate 14, and the output end of the motor 2 18 on the mounting plate 2 17 is connected to the end of the screw 16.

[0049] The principles and beneficial effects of the above scheme are:

[0050] After the motor 2 18 is started, its output end rotates forward or reverse, driving the screw 16 to rotate forward or reverse. Under the sliding cooperation of the mounting plate 2 17, the sliding plate 14 drives the beating plate 5 to approach or move away from the preform. Therefore, when the beating plate 5 approaches the preform and when the needle starts to puncture the preform, the beating plate 5 can apply a greater beating force to the preform. When the beating plate 5 moves away from the preform and when the needle starts to puncture the preform, the beating plate 5 can apply a smaller beating force to the preform.

[0051] Example 4: Reference Figures 1-16 , the tip of the needle is arranged toward the tooling 19 .

[0052] The principles and beneficial effects of the above scheme are:

[0053] The preform is fixed on the tooling 19. When the device starts working, the needle punctures the preform fixed on the tooling 19, and at the same time the beating piece 5 is beating. The tooling 19 improves the stability of the placement of the preform, and further avoids the movement of the bulging part when the beating piece 5 is beating, thereby ensuring the quality of the beating.

[0054] Example 5: Reference Figures 1-16 The second mounting plate 17 is connected to a third motor 20 , and an output end of the third motor 20 is connected to a guide wheel 21 .

[0055] The guide wheel 21 is frictionally engaged with the longitudinal slide rail 22 , and the longitudinal slide rail 22 is slidingly engaged with the second mounting plate 17 .

[0056] The principles and beneficial effects of the above scheme are:

[0057] After the motor 3 20 is started, its output end rotates forward or reverse, and then the guide wheel 21 rotates forward or reverse. The guide wheel 21, which is frictionally matched with the longitudinal slide rail 22, drives the mounting plate 2 17 to move upward or downward, and finally the relative height between the flapping piece 5 and the preform can be adjusted.

[0058] Example 6: Reference Figures 1-16 The end opening of the connecting rod 4 is slidably connected with a connecting rod three 23, the end of the connecting rod three 23 is connected to the inner wall of the connecting rod 4 through a spring 24, the other end of the connecting rod three 23 is connected to the end face of the flapping piece 5, the end face of the flapping piece 5 is connected to the open end of the outer shell 26, the other end face of the flapping piece 5 is provided with a filter 25, the open end of the outer shell 26 is set toward the filter 25, the filter 25 is set toward the tooling 19, and the outer shell 26 is connected to a suction component 27.

[0059] The principles and beneficial effects of the above scheme are:

[0060] One end of the spring 24 is connected to the inner wall of the connecting rod 4, and the other end of the spring 24 is connected to the end of the connecting rod 3 23. Therefore, the spring 24 is placed inside the connecting rod 4. The connecting rod 4 protects the spring 24 and prevents it from contacting with the outside air, thereby preventing it from rusting and oxidation, thereby extending its service life.

[0061] During acupuncture, the flapping piece 5 moves synchronously toward the preform, and flaps the preform. The flapping function is realized by the flapping piece 5 contacting the surface of the preform. The magnitude of the flapping force is changed by changing the length and diameter of the spring 24. When the required flapping force is large, the length of the spring 24 is increased, or its diameter is reduced. When the required flapping force is small, the length of the spring 24 is reduced, or its diameter is increased.

[0062] When the flapping piece 5 comes into contact with the preform, the flapping piece 5 drives the connecting rod 3 23 to move toward the inside of the connecting rod 4, thereby compressing the spring 24. When the flapping piece 5 ends its contact with the preform, under the elastic force of the spring 24, the connecting rod 3 23 moves away from the connecting rod 4, preparing for the next flapping.

[0063] When the beating sheet 5 is beating, the filter screen 25 provided thereon comes into contact with the preform. Broken fibers will appear in the yarn after needling. The fibers pass through the filter screen 25 under the suction action of the suction assembly 27 and enter the housing 26 for uniform collection. This can further assist the beating sheet 5 in eliminating bulging on the surface of the preform, improve the overall uniformity and thickness of the product, and further improve the aesthetics of the product.

[0064] When the preform needs to undergo secondary processing after needling, such as coating and hot pressing, collecting the fiber debris in advance can avoid reducing the bonding strength after the secondary processing, thereby ensuring the overall structural strength of the preform and reducing the occurrence of defects;

[0065] The collection of fiber debris can improve the health of operators, avoid the occurrence of lung diseases, and improve the hygiene of the work site. When processing prefabricated bodies made of flammable fibers, the collection of fibers can avoid the occurrence of fire or explosion, thereby improving the safety of operators and on-site equipment.

[0066] In order to ensure that the beating sheet 5 can fully beat the surface of the preform after needle punching, the beating sheet 5 has a sufficient design margin, that is, the area of ​​the beating sheet 5 is larger than the area of ​​the working area composed of the multiple needles, and the area of ​​the filter screen 25 is larger than the area of ​​the working area composed of the multiple needles, so as to ensure that the preform is fully beaten;

[0067] Furthermore, after the suction assembly 27 is activated, the fiber debris is collected through the filter holes of the filter screen 25, and the debris will not accumulate in the equipment at the work site, thereby preventing equipment malfunction.

[0068] Example 7: Reference Figures 1-16 The suction assembly 27 includes: a pump casing 28, a rotating shaft 29, a fan blade 30 and a storage tank 31. The top surface of the outer casing 26 is connected to one side of the pump casing 28 through a pipe 32. The pipe 32 is arranged toward the filter 25. The pump casing 28 is rotatably connected to the rotating shaft 29. The fan blade 30 connected to the rotating shaft 29 is placed inside the pump casing 28. The other side of the pump casing 28 is connected to the end of the storage tank 31 through a second pipe 33. One side of the storage tank 31 is connected to the end of an exhaust pipe 34. The other end of the exhaust pipe 34 is arranged away from the outer casing 26 and is connected to a second filter 35. A one-way valve is connected inside the second pipe 33.

[0069] The one-way valve includes: a mounting shell 53, a mounting rod 54, a torsion spring 55 and a rubber plate 56. The pipe 2 33 is connected to the mounting shell 53, and the mounting rod 54 is rotatably connected to the mounting shell 53. The end of the mounting rod 54 that passes through the outside of the mounting shell 53 is connected to a positioning plate, and the positioning plate is connected to the side wall of the mounting shell 53 through the torsion spring 55. The mounting rod 54 is connected to the rubber plate 56. The rubber plate 56 is in contact with the inner wall of the mounting shell 53 facing the storage tank 31, and the mounting rod 54 is arranged above the middle of the rubber plate 56.

[0070] The principles and beneficial effects of the above scheme are:

[0071] When the device is performing suction, the rotation of the rotating shaft 29 drives the fan blades 30 to rotate in the pump housing 28. The fiber debris entering the outer shell 26 enters the pump housing 28 through the pipe 32 and enters the storage tank 31 through the second pipe 33. To ensure smooth suction, the storage tank 31 is connected to the exhaust pipe 34. The second filter 35 on the exhaust pipe 34 can limit the fiber debris inside the storage tank 31 to prevent the fiber debris from being accidentally discharged. While the suction work is in progress, the fiber debris enters the storage tank 31 through the one-way valve in the second pipe 33. After the work is completed, the one-way valve can prevent the collected fiber debris from returning to the outer shell 26.

[0072] When suction begins, fiber debris in the second pipe 33 enters the mounting shell 53. Under the action of air pressure and the rotation cooperation of the mounting shell 53 and the mounting rod 54, the rubber plate 56 is deformed, releasing the air containing fiber debris into the mounting shell 53. At this time, the mounting rod 54 rotates to a certain extent, and the torsion spring 55 twists and stores energy. When suction ends, the mounting rod 54 drives the rubber plate 56 to return to its original position under the elastic force of the torsion spring 55, and re-seals the second pipe 33 to prevent fiber debris from returning to the outer shell 26. The mounting rod 54 is arranged above the middle part of the rubber plate 56, so that when suction begins, the rubber plate 56 drives the mounting rod 54 to rotate to a certain extent, preventing the rubber plate 56 from deforming too much and ending the sealing of the second pipe 33. The rubber plate 56 is arranged to control the sealing and sealing end of the second pipe 33, which not only reduces the complexity of the structure, but also prevents the accumulation of fiber debris in the mounting shell 53 and the jamming of the rubber plate 56.

[0073] Example 8: Reference Figures 1-16 The rotating shaft 29 is rotatably connected to the flapping piece 5, and the rotating shaft 29 is connected to a gear 36 and a crown ratchet gear 37. The gear 36 is meshed with a gear 2 38, and the gear 2 38 is rotatably connected to the flapping piece 5. The gear 2 38 is meshed with a rack 39, and the top of the rack 39 is slidably connected to the side wall of the connecting rod 4. The top side wall of the rack 39 is connected to the end of a spring 2 40, and the other end of the spring 2 40 is connected to the side wall of the connecting rod 4. Each tooth top of the rack 39 is provided with a bevel 41, and a connecting rod 42 is slidably connected to the flapping piece 5. A stopper 43 is connected to the end of the connecting rod 42, and a spring 34 is connected between the stopper 43 and the flapping piece 5. The bevel 2 45 at the bottom of the stopper 43 frictionally cooperates with the gear 36.

[0074] The number of teeth on gear 36 is smaller than that on gear 2 38 .

[0075] The principles and beneficial effects of the above scheme are:

[0076] After the flapping piece 5 contacts the preform, the flapping piece 5 moves toward the inside of the connecting rod 4, and the rack 39 drives the gear 2 38 meshing with it to rotate, and the gear 2 38 drives the gear 36 meshing with it to rotate. Since the number of teeth of the gear 36 is smaller than the number of teeth of the gear 2 38, the displacement of the flapping piece 5 can be converted into the rotation of the gear 36, and the gear 36 drives the rotating shaft 29 and the crown ratchet gear 37 to rotate synchronously. Therefore, during the movement of the flapping piece 5, the rotating shaft 29 rotates continuously to ensure that after the filter screen 25 contacts the preform, the fiber debris on the surface of the preform can be subjected to continuous suction force, thereby ensuring that the suction work is carried out continuously and the fiber debris is fully sucked out;

[0077] When the gear 36 rotates synchronously, the teeth of the gear 36 frictionally engage with the inclined surface 2 45 at the bottom of the stopper 43, and the stopper 43 and the connecting rod 4 42 slide back and forth on the flapping piece 5, and the spring 3 44 repeatedly compresses and extends;

[0078] When the flapping piece 5 ends its contact with the preform, the distance between the connecting rod 4 and the flapping piece 5 increases, and the rack 39 moves upward relative to the flapping piece 5. The inclined surface 41 of the top of the tooth on the rack 39 frictionally cooperates with the teeth of the gear 2 38. The rack 39 reciprocates left and right relative to the connecting rod 4, and the spring 2 40 is repeatedly compressed and extended. At this time, the top of the stopper 43 contacts and cooperates with the teeth of the gear 36, preventing the gear 36 from reversing and thus preventing the rotating shaft 29 from reversing. Therefore, the flow direction of the air in the shell 26 is only from the preform into the interior of the shell 26, and there is no output from the interior of the shell 26 to the preform, thereby preventing some debris collected in the shell 26 from being accidentally discharged, and preventing the fiber debris from secondary contamination of the preform;

[0079] The unidirectional flow of air in the housing 26 is based on the unidirectional rotation of the rotating shaft 29. The arrangement of the inclined surface 41 and the second inclined surface 45 prevents the second gear 38 and the gear 36 from rotating in the opposite direction. At the same time, the second inclined surface 45 ensures the forward rotation of the second gear 38 and the gear 36. This not only simplifies the structure of the mechanism, but also ensures that the mechanism operates smoothly without mechanical interference, thereby improving the rationality of the mechanism.

[0080] The setting of gear parts and rack parts in the mechanism reduces the difficulty of processing and obtaining parts, improves the efficiency of device manufacturing, and reduces the difficulty of device manufacturing under various production conditions;

[0081] After the flapping piece 5 contacts the preform, it begins to move toward the connecting rod 4. Before the flapping piece 5 finishes moving toward the connecting rod 4, the rack parts and the gear parts work together during this process, which is converted into continuous rotation of the rotating shaft 29. The rotation of the rotating shaft 29 is realized by the rotation of the gear 36. The rotation of the gear 2 38 can increase the rotation speed of the gear 36. Therefore, each time the flapping piece 5 contacts the preform, there is enough air pressure to absorb and collect the fiber debris.

[0082] Example 9: Reference Figures 1-16The inclined surface three 46 of the crown ratchet gear 37 is set toward the rack 39, and the inclined surface three 46 is frictionally matched with the inclined surface four 47. The inclined surface four 47 is set at the top of the push block 48, and the end of the push block 48 is connected to the end of the push rod 49. The push rod 49 is slidably connected to the shell 26. A spring four 50 is connected between the push block 48 and the shell 26. The other end of the push rod 49 is placed in the shell 26 and is connected to a cutting piece 51. The cutting piece 51 is slidably matched with the filter screen 25. A plurality of cutting holes 52 are opened on the cutting piece 51. The cutting holes 52 are staggered with the filter holes of the filter screen 25 to seal the interior of the shell 26.

[0083] The principles and beneficial effects of the above scheme are:

[0084] As the shaft 29 rotates, the crown ratchet gear 37 rotates synchronously, and after the bevel three 46 contacts the bevel four 47, the push block 48 is driven to move toward the inside of the shell 26. Under the conditions of continuous friction fit and repeated compression and reset of the spring four 50, the push block 48 and the push rod 49 reciprocate relative to the shell 26, thereby causing the cutting blade 51 to reciprocate. Since the cutting holes 52 on the cutting blade 51 seal the filter holes of the filter screen 25, when the mechanism finishes working, the interior of the shell 26 can be sealed by the cutting blade 51, further improving the sealing effect of the interior of the shell 26, and preventing the fiber debris that has not entered into 31 from being discharged before the flapping piece 5 contacts the preform. When the flapping piece 5 contacts the preform, the open end of the shell 26 is sealed toward the open end of the filter screen 25. Even when the suction assembly 27 is in a non-suction state, the fiber debris in the shell 26 will not fly around through the filter holes of the filter screen 25.

[0085] After the suction assembly 27 is started, the air pressure inside the shell 26 decreases, and some fiber debris first passes through the filter holes of the filter screen 25, and then enters the shell 26 through the cutting hole 52. The ends of the remaining protruding fibers that are still connected to the preform will pass through the cutting hole 52 under the action of negative pressure and enter the shell 26 under the condition of reduced air pressure in the shell 26. As the rotating shaft 29 rotates, the cutting blade 51 moves back and forth in the shell 26. The cutting blade 51 uses its cutting hole 52 to cut the remaining fibers, thereby forming new fiber debris, which continues to be sucked and collected uniformly under the action of the negative pressure of the shell 26.
