Description

Technical Field

[0001] This relates to the field of non-textile material processing and production, and in particular to a three-dimensional non-textile material reinforcement device. Background Technology

[0002] The flat preform, made from non-woven materials, is an intermediate material and cannot be used directly. It requires further processing, including punching holes and inserting pins to enhance its performance, to obtain the finished product. Current technology involves manual punching, pin insertion, and cutting, followed by using an electric iron to flatten the pins onto the flat preform. The disadvantages of this existing technology are: (1) The labor intensity of personnel is high, the work efficiency is low, and the labor cost is high; (2) Manual drilling has low precision. The positioning of the hole is inaccurate when using a hand drill, resulting in deviation and unevenness in the drilling position; (3) Due to the varying skill levels of personnel, manual pin implantation may result in inaccurate implantation dimensions or breakage of the pin wire, posing a risk to product quality and making it impossible to guarantee the consistency of product quality. (4) Low precision during manual cutting results in inconsistent cutting lengths of the pin wires; (5) The angle cannot be kept consistent when manually flattening; Therefore, it is necessary to optimize the structure of this acupuncture device to overcome the above-mentioned defects. Summary of the Invention

The cutting edge plane of the pneumatic scissors forms a 60° angle with the axis where the end mounting needle is located. When the wire feeding is complete and the pin wire needs to be cut, the slide cylinder drives the pneumatic scissors forward to reach below the end mounting pin, where the pneumatic scissors cut the pin wire. After cutting, the slide cylinder drives the pneumatic scissors to retract.

[0013] In one embodiment, the hot pressing assembly includes a hot pressing mounting plate, on which a cylinder with a guide rod is connected. The telescopic end of the cylinder with the guide rod is connected to an upper adapter plate, a lower adapter plate, and a plurality of linear connecting bearings. Each linear connecting bearing is fixed through the upper adapter plate. A connecting shaft is provided between the lower adapter plate and each linear connecting shaft. The bottom of the lower adapter plate is provided for the hot pressing plate.

[0014] The technical advantages of this application are: (1) It solves the problems of high labor intensity, low work efficiency and high labor cost. The staff installs the rolled pin wire onto the material roll wheel equipment. The pin wire is guided by the guide groove and then passes through the punching and feeding assembly.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that all squareness indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the squareness indicator will also change accordingly.

[0028] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] like Figures 1 to 9 As shown in one embodiment of this application, this application provides a three-dimensional nonwoven material reinforcement device.

[0030] like Figure 1 As shown: A three-dimensional non-woven material reinforcement device includes a frame assembly 1, a movable crossbeam assembly 2 mounted on the frame assembly 1, a lifting assembly 3, a punching and wire feeding assembly 4, a pneumatic shear assembly, and a hot pressing assembly. Through fully automated operation, the device fixes the flat preform by punching and feeding wire, performing punching, wire feeding, hot pressing, and wire cutting. All operations are completed mechanically, solving the problems of high labor intensity, low work efficiency, and high labor costs. Only manual loading and unloading are required, enabling standardized and unified manufacturing of the entire flat preform and comprehensively improving its overall quality.

[0031] like Figure 2 As shown: The frame assembly 1 includes a frame 5. The frame 5 is provided with a left protective cover 9, a right protective cover 12, a front baffle 10 and a front door 11 around its circumference. The upper surface of the frame 5 is provided with a cover plate 13 and a bottom hole plate 6. The bottom of the frame 5 is provided with feet 15. The frame 5 is provided with a first helical rack 7 and a first linear slide rail 8 on both sides. The first helical rack 7 and the first linear slide rail 8 are arranged perpendicular to the front of the frame 5 to facilitate the longitudinal movement of the moving beam assembly 2.

[0032] The left protective cover 9 and the right protective cover 12 are respectively fastened to the sides of the first oblique rack 7 and the first linear slide rail 8 on both sides, serving to protect and isolate them.

[0033] The movable crossbeam assembly 2 can move back and forth along the first oblique rack 7 and the first linear slide rail 8 on both sides of the frame 5. The bottom hole plate 6 is used to place the flat precast body during operation. The frame assembly 1 is equipped with an electrical control box 14, which is electrically connected to and controls the movable crossbeam assembly 2, the lifting assembly 3, the punching and wire feeding assembly 4, the pneumatic shear 67 assembly, and the hot pressing assembly 44.

[0034] The electrical control box 14 is located inside the rear side of the frame. Electrical control components are installed inside the electrical control box 14. The electrical control box 14 is equipped with wires, control boards and control buttons to realize the fully automated operation of the entire set of equipment.

[0035] In this invention, the movable crossbeam assembly 2 is slidably connected to the frame assembly 1. Crossbeam drive devices are installed on the left and right sides of the movable crossbeam assembly 2, and the crossbeam drive devices drive the movable crossbeam assembly 2 to reciprocate back and forth. Specifically, such as Figure 3-4 As shown, the movable crossbeam assembly 2 includes a movable crossbeam 16 and a second oblique rack 17 and a second linear slide rail 18 disposed on the movable crossbeam 16. The movable crossbeam 16 is generally rectangular, the second oblique rack 17 is disposed on the upper surface of the movable crossbeam 16, and there are two second linear slide rails 18, which are disposed parallel to each other on the front side wall of the movable crossbeam 16.

[0036] like Figure 3 As shown: Two crossbeam drive devices are symmetrically arranged at both ends of the moving crossbeam 16. Each crossbeam drive device is equipped with a motor protective cover 28. Each crossbeam drive device includes a first servo motor 20 and a first reducer 19. The end of the first reducer 19 is equipped with a first helical gear 21 that meshes with the first helical rack 7. The bottom of the crossbeam drive device is equipped with a first linear slider 22 that slidably meshes with the first linear slide rail 8. The lifting assembly 3 moves back and forth along the second helical rack 17 and the second linear slide rail 18.

[0037] Furthermore, in order to fix the flat preform during drilling, so that the hole spacing is uniform after drilling and the pin wires are evenly connected to each hole, a device for fixing the flat preform is needed.

[0038] Therefore, two sets of clamping components are installed below the moving crossbeam assembly 2, such as... Figure 3-4 As shown, each of the clamping components includes a clamping cylinder 24 and a clamping plate 23. The clamping plate 23 is used to clamp and fix the flat preform onto the upper surface of the frame assembly 1. A floating joint 27 is provided between the clamping cylinder 24 and the clamping plate 23. Each clamping plate 23 is also connected to a guide shaft 26 and a linear bearing 25. Two pairs of guide shafts 26 and linear bearings 25 are provided to provide support and guidance. Each linear bearing 25 and the clamping cylinder 24 are fixed on the moving crossbeam assembly 2. When the cylinder rod of the clamping cylinder 24 extends, the clamping plate 23 descends to clamp the flat preform. When the cylinder rod of the clamping cylinder 24 retracts, the clamping plate 23 rises. At this time, the moving crossbeam assembly 2 can move back and forth.

[0039] The lifting assembly 3 is slidably mounted on the moving crossbeam assembly 2. The lifting assembly 3 adjusts and controls the lifting of the punching and wire feeding assembly 4. The lifting assembly 3 is equipped with a transverse drive device, which pushes the lifting assembly 3 to reciprocate left and right along the crossbeam assembly. The lifting assembly 3 uses a third servo motor 30, a third reducer 31, and a ball screw 33 to rotate and drive the punching and wire feeding assembly 4 to move up and down for punching and wire feeding. This ensures high precision, guarantees consistent pin insertion depth in each hole, and ensures consistent product quality.

[0040] Specifically, such as Figure 5-6 As shown: The lifting assembly 3 includes a fixed base plate 29 and a third servo motor 30, a third reducer 31 and a motor base 32 disposed on the front side of the fixed base plate 29. The output end of the third reducer 31 is connected to a ball screw 33. The other end of the ball screw 33 is fixed to the fixed base plate 29 by a screw support 34. A protective plate 39 is provided on one side of the ball screw 33. The fixed base plate 29 is also provided with a third linear slide rail 47 and four third linear sliders 40. The third linear sliders 40 are divided into two groups, both facing vertically downward, for sliding cooperation with the two third linear sliders 40.

[0041] One end of the punching and wire feeding assembly 4 is rotatably fixed to the ball screw 33 via the ball screw nut assembly 42, and the other end of the punching and wire feeding assembly 4 is fixed to the third linear slider 40. The third servo motor 30 and the third reducer 31 drive the ball screw 33 to rotate, so that the punching and wire feeding assembly 4 moves up and down along the third linear slide rail 47.

[0042] The lateral drive device is located on the rear side of the fixed base plate 29. The lateral drive device includes a second servo motor 35, a second reducer 36, a second helical gear 37, and a second linear slider 38. The second helical gear 37 and the second helical rack 17 are geared together, and the second linear slider 38 and the second linear slide rail 18 are slidably engaged.

[0043] The punching and wire feeding assembly 4 is positioned by the second servo motor 35, the second reducer 36, the second helical gear 37 and the second linear slider 38 in the drive device. It has high repeatability and high accuracy of punching position spacing, ensuring consistent product quality of the flat preform.

[0044] The front side of the first wire feeding mounting plate 41 is also provided with a guide groove 46 and a material winding wheel 45. The pin wire on the material winding wheel 45 flows into the punching and feeding assembly 4 through the guide groove 46. The operator installs the rolled pin wire onto the material winding wheel 45. After the pin wire is guided by the guide groove 46 and passes through the punching and feeding assembly 4, the equipment is started. The equipment runs automatically to punch, insert pins, cut, and flatten the flat preform according to the required spacing and quantity, reducing manual operation.

[0045] The punching and wire feeding assembly 4 drives the punching spindle 61 to rotate at high speed through the punching servo motor 56. The end mounting pin 63 at the end of the punching spindle 61 punches holes in the flat preform. At the same time, the wire feeding servo motor 50 drives the rubber-coated wheel 51 to feed the pin wire to the required length through the through hole inside the punching spindle 61 and the end mounting pin 63. The punching and wire feeding assembly 4 is slidably mounted on the first wire feeding mounting plate 41, and the entire punching and wire feeding assembly 4 moves up and down by rotating the ball screw 33.

[0046] Specifically, such as Figure 7-8 As shown: The drilling wire feeding assembly includes a first wire feeding mounting plate 41 and a second wire feeding mounting plate 48. One end of the first wire feeding mounting plate 41 is rotatably fixed to the ball screw 33 via the ball screw nut assembly 42. One end of the first wire feeding mounting plate 41 is fixed to the third linear slider 40. A support plate 49 is provided between the second wire feeding mounting plate 48 and the first wire feeding mounting plate 41. In order to accommodate multiple motors and equipment, the support plate 49 and the second wire feeding mounting plate 48 are added to expand the connection part of the equipment.

[0047] like Figure 8 As shown: The second wire feeding mounting plate 48 is equipped with a wire feeding component 43, a punching component, and a pneumatic scissor assembly. The wire feeding component 43 includes a wire feeding servo motor 50, a rubber-coated wheel 51, a pressure plate 55, and a pressure roller 54. The wire feeding servo motor 50 is located between the second wire feeding mounting plate 48 and the first wire feeding mounting plate 41. The rubber-coated wheel 51 is sleeved on the main shaft of the wire feeding servo motor 50. The pressure plate 55 is rotatably fixed on the second wire feeding mounting plate 48 by a fulcrum step screw 53. The pressure roller 54 is rotatably fixed on the pressure plate 55. A spring is provided between the pressure plate 55 and the second wire feeding mounting plate 48 to press the pressure roller 54 against the rubber-coated wheel 51. A wire guide tube 52 is provided above and below the rubber-coated wheel 51, respectively. A spring is installed on the pressure plate 55, and the other side of the spring is fixed on the second wire feeding mounting plate 48. That is, the pressure roller 54 presses the rubber-coated roller 51 tightly under the action of the spring, which enables the pin wire to be fed into the punching spindle 61 under high pressure.

[0048] The drilling components include a bearing housing 62, a drilling spindle 61, a drilling servo motor 56, and a timing belt 60. The drilling servo motor 56 is fixed on the second wire feeding mounting plate 48 via a motor mounting plate 57. A driving timing pulley 58 is provided on the drilling servo motor 56, and a driven timing pulley 66 is provided on the drilling spindle 61. The driving timing pulley 58 and the driven timing pulley 66 are driven by the timing belt 60. A timing belt 60 cover 70 is also provided on the second wire feeding mounting plate 48. The drilling spindle 61 is fixed on the bearing housing 62 via a lower bearing 64 and an upper bearing 65. The upper end of the drilling spindle 61 is connected to a wire guide tube 52, and the lower end of the drilling spindle 61 is provided with an end mounting pin 63.

[0049] The end mounting pin 63 not only serves to rotate and punch holes, but also guides the pin wire through the hole.

[0050] The present invention uses a hollow punching spindle 61 and an end mounting pin 63 for punching. That is, the punching spindle 61 and the end mounting pin 63 have wire holes through which pin wires can be inserted. At the same time as punching, the pin wires are inserted through the wire holes and the wire feeding operation is completed under the drive of the wire feeding servo motor 50. Punching and wire feeding are carried out simultaneously, which is highly efficient.

[0051] Pneumatic scissors assembly: The pneumatic scissors 67 are moved by the slide cylinder 69 to complete the cutting action. They are used to cut pin wires. The pneumatic scissors 67 are used to cut pin wires. The position of the pneumatic scissors 67 is positioned by the lifting assembly 3 and the slide cylinder 69 to ensure that the cutting length is uniform and consistent each time.

[0052] like Figure 8 As shown, in one embodiment of the present invention, the pneumatic scissors assembly includes a slide cylinder 69, a scissor mounting plate 68, and pneumatic scissors 67. The slide cylinder 69 is fixed on the second wire feeding mounting plate 48, the scissor mounting plate 68 is fixed on the slide cylinder 69, and the pneumatic scissors 67 is disposed at one end of the scissor mounting plate 68. The cutting edge plane of the pneumatic scissors 67 forms a 60° angle with the axis where the end mounting needle 63 is located. When the wire feeding is complete and the pin wire needs to be cut, the slide cylinder 69 drives the pneumatic scissors 67 forward to reach below the end mounting pin 63, and the pneumatic scissors 67 cuts the pin wire. After the cutting is completed, the slide cylinder 69 drives the pneumatic scissors 67 to retract.

[0053] Hot pressing assembly 44: The hot pressing assembly 44 is installed on the moving crossbeam assembly 2. The hot pressing assembly 44 can press the cut pin wires flat onto the flat preform through the hot pressing plate 77. The hot pressing plate 77 automatically heat-presses the pin wires and the flat preform to ensure that the pressing angle is uniform and consistent without skewing.

[0054] like Figure 9As shown, the hot pressing assembly 44 involved in this invention includes a hot pressing mounting plate 71. A cylinder 72 with a guide rod is connected to the hot pressing mounting plate 71. An upper adapter plate 74, a lower adapter plate 76, and a plurality of linear connecting shafts 75 bearings 73 are connected to the telescopic end of the cylinder 72. Each linear connecting shaft 75 bearing 73 is fixedly fixed to the upper adapter plate 74. A connecting shaft 75 is provided between the lower adapter plate 76 and each linear connecting shaft 75. The bottom of the lower adapter plate 76 is provided with a hot pressing plate 77.

[0055] like Figures 1-2 In order to prevent impurities and debris from getting into the rack and toothed rail, a first track elastic protective cover 78 and a second track elastic protective cover 79 that can slide elastically are provided on the frame assembly 1. There are two first track elastic protective covers 78, which abut against the two sides of the first reducer 19 respectively and move with the first reducer 19. They both cover the first helical rack 7 and the first linear slide rail 8. There are also two second track elastic protective covers 79, which abut against the two sides of the second reducer 36 respectively and move with the second reducer 36. They both cover the second helical rack 17.

[0056] Working principle: A three-dimensional nonwoven material reinforcement process includes the following steps: S1 Material Preparation: Place the coiled pin wire into the feeding coil 45, guide one end of the pin wire through the guide groove 46, then through the upper wire guide tube 52, and the gap between the pressure roller 54 and the rubber-coated roller 51, and then through the lower wire guide tube 52 into the punching spindle 61, and then connect and fix it to the end mounting pin 63. At the same time, the operator places the flat preform onto the bottom hole plate 6 on the upper surface of the frame 5. S2 Moving Positioning Flat Preform: Start the first servo motors 20 on both sides of the moving crossbeam 16, driving each first reducer 19 and the first helical gear 21 to move along the first helical rack 7. The first linear slider 22 slides and guides on the first linear slide rail 8, so that the moving crossbeam 16 moves to the front end of the flat preform. Then start the second servo motor 35, driving the second reducer 36 and the second helical gear 37 to move along the direction of the second helical rack 17, so that the lifting assembly and the drilling and wire feeding assembly move on the moving crossbeam to the rightmost side of the flat preform. S3 Fixing the precast flat plate: Activate the clamping cylinder 24 in the clamping assembly. The clamping cylinder 24 extends to press the clamping plate 23 against the entire precast flat plate, thus completing the fixing. S4, Drilling and laying pin wire: When the third servo motor 30 is started, it drives the third reducer 31 and the ball screw 33 to rotate. Through the ball screw nut assembly 42, it drives the wire feeding unit 43 to move up and down quickly. At the same time, the second servo motor 35 is started, and the entire drilling and wire feeding assembly 4 moves at a constant speed on the moving crossbeam 16. At the same time, the drilling servo motor 61 is started to drive the active synchronous wheel 58, which drives the driven synchronous wheel 66 to rotate through the synchronous belt 60, so that the drilling spindle 61 rotates and drives the end mounting pin 63 to rotate quickly, so that the end mounting pin 63 can quickly drill holes in the flat preform. At the same time, the wire feeding servo motor 50 is started to drive the rubber-coated wheel 51, so that the pin wire continuously moves towards the end mounting pin 63 and passes through and is laid in the hole of the flat preform. At the same time, the cylinder 72 with guide rod in the hot pressing assembly 44 extends, so that the hot pressing plate 77 is pressed on the upper surface of the flat preform after the pin wire is laid, so that the pin wire and the flat preform are fully implanted. S5 Cuts the pin wire: When the punching and wire feeding assembly 4 moves to the leftmost side of the flat preform, the slide cylinder 69 moves forward, causing the pneumatic scissors 67 to move below the end mounting pin 63, the pneumatic scissors 67 cuts the pin wire, and then the slide cylinder 69 retracts. S6 continuously repeats steps S1-S5 until the entire flat preform is covered with pin wire, and then the operator replaces it with a new flat preform.
