Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a nonwoven fabric composite perforation device. Background Technology

[0002] In the medical and health field, it is used to produce products such as masks, surgical gowns, and medical dressings. The perforated design improves the breathability and liquid absorption of the materials. In the automotive manufacturing industry, it can be used to composite perforated nonwoven fabrics for interior decoration, enhancing sound insulation and heat insulation while reducing weight. In home decoration, it can be used to perforate and composite nonwoven fabrics such as curtains and sofa fabrics, increasing aesthetics and functionality.

[0003] In the existing technology, some composite perforation equipment for nonwoven fabrics uses a motor to drive the piercing needle to move up and down to achieve perforation of the nonwoven fabric. Through the engagement of irregular blocks, the hollow block connected to the insertion needle is driven to rise and fall to complete the perforation operation. There is also thermal perforation technology, which uses heating elements to heat and melt the nonwoven fabric to form holes. It is often used for processing nonwoven fabrics with a high content of heat-melting fibers.

[0004] However, in actual use, it is impossible to position the material during perforation, and the material is prone to shift during processing, resulting in perforation position deviation, inconsistent hole size, and affecting product consistency. Material wrinkling or displacement during perforation can also damage the equipment's puncture needle, making it difficult to meet the processing requirements of high-precision nonwoven fabric products. In response to the above problems, a nonwoven fabric composite perforation device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a nonwoven fabric composite perforation device, which aims to improve the problem that some perforation devices in the prior art cannot achieve accurate positioning during the perforation process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nonwoven fabric composite perforation device includes a device body, a control panel fixedly connected to the outside of the device body, a take-up roller fixedly connected to the right side of the device body, an unwind roller fixedly connected to the left side of the device body, an operating table fixedly connected to the inside of the device body, a positioning mechanism fixedly connected to the outside of the device body, and a quick-release mechanism fixedly connected to the outside of the device body.

[0009] As a further description of the above technical solution:

[0010] The support assembly includes a buffer rod, which is fixedly connected to the outside of the positioning plate, and a tension spring is sleeved on the outside of the buffer rod.

[0011] As a further description of the above technical solution:

[0012] The quick-release mechanism includes a hydraulic cylinder, which is externally fixedly connected to the inside of the device body, and a follower rod is fixedly connected to the drive end of the hydraulic cylinder.

[0013] As a further description of the above technical solution:

[0014] The follower rod is detachably connected to a connecting block, and a perforated plate is fixedly connected to the bottom of the connecting block;

[0015] As a further description of the above technical solution:

[0016] The follower rod has multiple threaded grooves inside, and bolts are threaded to the outside of the threaded grooves. The external threads of the bolts are connected to the inside of the connecting block.

[0017] As a further description of the above technical solution:

[0018] The follower rod has multiple limiting holes inside, and a limiting rod is slidably connected inside the limiting holes. A return spring is sleeved on the outside of the limiting rod.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the motor drives the connecting rod to move, which in turn drives the rack plate to move, which in turn drives the positioning plate to move. This allows the nonwoven fabric to be positioned during perforation, preventing fabric shifting and wrinkling, ensuring accurate perforation position, improving hole uniformity and pattern consistency, avoiding damage to the perforating needle due to fabric movement, improving composite quality, and making production more stable.

[0025] 2. In this utility model, by rotating the bolt, the bolt drives the connecting block to move, and the limit rod drives the tension spring to move, so that the slider slides in the groove, and then the cleaning plate reciprocates at the bottom of the slotted hole.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a nonwoven fabric composite perforation device, comprising a device body 1, a control panel 2 fixedly connected to the outside of the device body 1, a take-up roller 3 fixedly connected to the outside right side of the device body 1, high-precision bearings installed at both ends of the take-up roller 3, and the nonwoven fabric that has completed the composite perforation process is evenly wound on the roller body. The diameter and length of the take-up roller 3 are customized according to actual production needs to meet the requirements of different roll diameters and outputs. An unwind roller 4 is fixedly connected to the outside left side of the device body 1. The unwind roller 4 rotates slowly under the action of the transmission mechanism to release the nonwoven fabric with constant tension, so that it smoothly enters the equipment for composite perforation processing. The unwind roller 4 is also equipped with a tension adjustment device, which can adjust the unwind tension according to the material and thickness of the nonwoven fabric to ensure the stability of the processing. An operating table 5 is fixedly connected inside the device body 1, a positioning mechanism is fixedly connected to the outside of the device body 1, and a quick-release mechanism is fixedly connected to the outside of the device body 1.

[0035] The positioning mechanism includes a motor 6, which is firmly fixed to the side wall inside the device body 1 by a special mounting bracket. Its output shaft is perpendicular to the working plane of the device body 1. The motor 6 can accurately adjust the speed and direction according to the requirements of the processing technology, providing a stable and reliable power source for the positioning mechanism. The motor 6 is externally fixedly connected to the inside of the device body 1. A connecting rod 7 is fixedly connected to the drive end of the motor 6. One end of the connecting rod 7 is tightly connected to the output shaft of the motor 6, and the other end extends into the working area of ​​the device body 1 for mounting a gear 8. Driven by the motor 6, the connecting rod 7 can rotate at high speed and accurately transmit power to the gear 8. The gear 8 is externally fixedly connected to the connecting rod 7.

[0036] The operating table 5 is externally fixedly connected to a support block 9, and the support block 9 is internally slidably connected to a connecting rod 11. The bottom of the connecting rod 11 is fixedly connected to a positioning plate 10. When the motor 6 drives the connecting rod 7 and the gear 8 to rotate, the rotation of the gear 8 can be converted into the linear motion of the rack plate 12, thereby realizing the precise position adjustment of the positioning plate 10. The connecting rod 11 is externally fixedly connected to the rack plate 12, and the positioning plate 10 is externally fixedly connected to multiple support components. The support components include a buffer rod 13. The buffer rod 13 is externally fixedly connected to the outside of the positioning plate 10, and a tension spring 14 is sleeved on the outside of the buffer rod 13. When the nonwoven fabric is subjected to external force, the buffer rod 13 will compress the tension spring 14. The elastic deformation of the spring absorbs and buffers the external force, ensuring the stability and integrity of the nonwoven fabric during the processing.

[0037] Reference Figures 3 to 5 The quick-release mechanism includes a hydraulic cylinder 15, which is externally fixedly connected to the inside of the device body 1. A follower rod 16 is fixedly connected to the drive end of the hydraulic cylinder 15. Under the drive of the hydraulic cylinder 15, the follower rod 16 can perform precise linear reciprocating motion along the axial direction. A connecting block 17 is detachably connected to the outside of the follower rod 16. A perforated plate 18 is fixedly connected to the bottom of the connecting block 17. The perforated plate 18 is precision stamped and ground to ensure the accuracy and quality of the perforation. Under the drive of the follower rod 16, a composite perforation operation is performed on the nonwoven fabric. Multiple threaded grooves 19 are opened inside the follower rod 16. Bolts 20 are threadedly connected to the outside of the threaded grooves 19. The bolts 20 and the follower rod 16 are quickly and firmly connected or disassembled, which facilitates the replacement or maintenance of the perforated plate 18.

[0038] The external thread of bolt 20 is connected to the inside of connecting block 17. Multiple limiting holes 21 are provided inside follower rod 16. The limiting holes 21 ensure that limiting rod 22 can move within a specified range. At the same time, it cooperates with other components to realize the limiting and positioning functions of connecting block 17 and perforated plate 18. Limiting rod 22 is slidably connected inside limiting hole 21. Return spring 23 is sleeved on the outside of limiting rod 22. Multiple opening slots 24 are provided on the top of operating table 5. Multiple sliding grooves 25 are provided inside operating table 5. Sliding slider 26 is slidably connected to the outside of sliding groove 25. Cleaning plate 27 is fixedly connected to the outside of sliding slider 26. Under the drive of sliding slider 26, cleaning plate 27 can slide horizontally along the bottom of opening slot 24 inside operating table 5. Through friction with the surface of operating table 5, cleaning perforated needles and preventing fiber blockage. The outside of cleaning plate 27 is slidably connected to the bottom of opening slot 24.

[0039] Working principle: The unwinding roller 4 rotates slowly under the drive of the transmission mechanism, so that it is laid out smoothly on the operating table 5. The motor 6 is started, so that the drive end of the motor 6 drives the connecting rod 7 to rotate at high speed, which in turn drives the gear 8 to rotate. The gear 8 meshes with the rack plate 12, converting the rotational motion into linear motion, which drives the connecting rod 11 and the positioning plate 10 to rise and fall vertically, positioning the nonwoven fabric. During the positioning process, if the nonwoven fabric is subjected to force, the buffer rod 13 compresses the tension spring 14, buffering the external force through elastic deformation.

[0040] The hydraulic cylinder 15 is activated, driving the follower rod 16 to move axially, which in turn moves the connecting block 17 and the perforated plate 18 downward. The perforated plate 18 is used to perform composite perforation on the nonwoven fabric. The slider 26 slides in the groove 25, causing the cleaning plate 27 to move. The cleaning plate 27 reciprocates on the surface of the perforation groove 24, cleaning the multiple perforation needles at the bottom of the perforated plate 18. When the perforated plate 18 needs to be replaced, the limit rod 22 is pulled out by overcoming the elastic force of the return spring 23, and the bolt 20 is unscrewed to remove the connecting block 17 and the perforated plate 18. After replacement, they are reinstalled and fixed to continue the composite perforation of the nonwoven fabric.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
