Description

Technical Field

[0001] This utility model relates to the field of ultrasonic wire cutting technology, specifically to an ultrasonic wire cutting mechanism. Background Technology

[0002] Ultrasonic cutting is a technology that achieves precision material processing through high-frequency mechanical vibration. Its core principle is to convert electrical energy into high-frequency vibration energy through an ultrasonic generator and transmit it to the cutting die, causing the material to melt and separate locally and instantaneously. Compared with traditional cutting methods, this technology has the advantages of not requiring a sharp cutting edge and producing a smooth and flat cutting surface. It can avoid problems such as chipping, fraying, or deformation of the material, while also having a fusion sealing effect. It is widely used in precision processing in fields such as aerospace composite materials, food packaging, and textile materials.

[0003] While existing ultrasonic inline cutting mechanisms meet user needs to some extent, they still have certain shortcomings. Specifically, ribbon materials are soft and easily deformed, and the fixed positioning structure of traditional mechanisms cannot dynamically adjust with the ribbon's feeding state. During continuous feeding, tension changes and slight shifts can easily lead to positioning deviations. Furthermore, the lack of precise positioning on both sides of the ribbon during cutting easily results in edge skewing and inconsistent cutting lengths, especially for narrow or patterned ribbons, where the defect rate is higher, affecting product aesthetics. Additionally, the positioning spacing is often fixed, requiring disassembly of the positioning components, adjustment of bolt positions, and reinstallation for ribbons of different widths, which is time-consuming. Moreover, installation errors during adjustment can easily lead to asymmetrical positioning, further affecting cutting accuracy and making it difficult to meet the production needs of diverse ribbon products. Therefore, this invention designs an ultrasonic inline cutting mechanism to solve the above problems. Utility Model Content

[0004] This utility model provides an ultrasonic in-line cutting mechanism, which can effectively solve the problems mentioned in the background art, such as the soft and easily deformable texture of ribbon materials, the inability of traditional fixed positioning structures to dynamically adjust with the ribbon conveying state, and the easy occurrence of positioning deviations due to tension changes and slight offsets during continuous conveying; the lack of precise positioning on both sides of the ribbon during cutting, which easily leads to edge skewing and inconsistent cutting lengths, especially for narrow or patterned ribbons, resulting in a higher defect rate and affecting the product's aesthetics. In addition, the positioning spacing is mostly a fixed design, requiring disassembly of the positioning components, adjustment of bolt positions, and reinstallation for ribbons of different widths, which is time-consuming and prone to asymmetry in positioning due to installation errors during adjustment, further affecting cutting accuracy and making it difficult to meet the production needs of diverse ribbon products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic wire cutting mechanism, including a working platform, a mounting frame fixedly connected to the top of the working platform, an ultrasonic cutting blade for cutting ribbon-like materials at one end of the mounting frame, the ultrasonic cutting blade being adjustable, and a positioning plate for positioning the ribbon-like materials at one end of the top of the working platform, the positioning plate moving synchronously with the ultrasonic cutting blade.

[0006] In a preferred embodiment of the ultrasonic wire cutting mechanism, an electric telescopic rod is fixed to one end of the top of the mounting frame, a mounting plate is fixedly connected to the bottom of the electric telescopic rod, and an ultrasonic cutting blade is fixedly connected to the bottom of the mounting plate.

[0007] In a preferred embodiment of the ultrasonic wire cutting mechanism, a connecting rod is mounted on one end of the mounting plate by screws, a slider is fixedly connected to one end of the connecting rod, a toothed rod is slidably connected to the outside of the slider, a gear is meshed with one end of the toothed rod, a bidirectional threaded rod is fixedly connected to one end of the gear, and a moving block is threaded to both ends of the bidirectional threaded rod, with a positioning plate mounted on the top of the moving block by screws.

[0008] In a preferred embodiment of the ultrasonic wire cutting mechanism, two positioning rollers are provided between the working platform and the mounting frame. A motor is fixedly mounted on one end of the mounting frame, and the output shaft of the motor is fixedly connected to one end of a positioning roller.

[0009] In the preferred embodiment of the ultrasonic wire cutting mechanism, one end of the slider is provided with a positioning groove, and one end of the toothed rod is provided with threaded grooves. A fixing screw is threadedly connected inside the threaded groove, and one end of the fixing screw is located inside the positioning groove.

[0010] In the preferred embodiment of the ultrasonic wire cutting mechanism, the bidirectional threaded rod is rotatably connected to the inside of the working platform, and the working platform has a moving groove at the position corresponding to the moving block, with the outer side of the moving block in contact with the inner wall of the moving groove.

[0011] In the ultrasonic wire cutting mechanism, preferably, the cross-section of the slider is T-shaped.

[0012] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use. 1. When the electric telescopic rod drives the ultrasonic cutting blade to move down for cutting, it simultaneously drives the rack to move through the connecting rod and slider. The rack meshes with the gear, which drives the bidirectional threaded rod to rotate, so that the positioning plates automatically move towards each other and fit against both sides of the material. In view of the soft and easily deformable characteristics of ribbon, the positioning plates can dynamically adapt to the ribbon conveying state, avoid edge skewing caused by offset, ensure accurate cutting position, improve the flatness and length consistency of the ribbon cut, and meet the precise cutting requirements of patterned ribbon. 2. By adjusting the position of the toothed rod on the slider and quickly fixing it with the fixing screw, the spacing of the positioning plate driven by the bidirectional threaded rod can be indirectly adjusted. It can adapt to ribbons of various widths without disassembling the positioning components. The positioning roller continuously feeds the ribbon, and the electric telescopic rod lifts and lowers to drive the positioning plate to open and close automatically. After cutting, the positioning plate is reset synchronously with the cutting blade, and continuous cutting can be achieved without manual intervention. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution for an ultrasonic wire cutting mechanism, including a working platform 1, a mounting frame 2 fixedly connected to the top of the working platform 1, an electric telescopic rod 3 fixedly connected to one end of the top of the mounting frame 2, a mounting plate 4 fixedly connected to the bottom of the electric telescopic rod 3, an ultrasonic cutting blade 5 fixedly connected to the bottom of the mounting plate 4, two positioning rollers 6 arranged between the working platform 1 and the mounting frame 2, a motor 7 fixedly mounted to one end of the mounting frame 2, and the output shaft of the motor 7 fixedly connected to one end of a positioning roller 6. One end of the mounting plate 4 is fitted with a connecting rod 8 by screws. One end of the connecting rod 8 is fixedly connected to a slider 9. A toothed rod 10 is slidably connected to the outside of the slider 9. One end of the toothed rod 10 is meshed with a gear 12. One end of the gear 12 is fixedly connected to a bidirectional threaded rod 13. Both ends of the bidirectional threaded rod 13 are threadedly connected to moving blocks 14. A positioning plate 15 is fitted to the top of the moving block 14 by screws.

[0017] The slider 9 has a positioning groove at one end, and the toothed rod 10 has threaded grooves evenly distributed at one end. A fixing screw 11 is threadedly connected inside the threaded groove. One end of the fixing screw 11 is inside the positioning groove, which facilitates fixing the toothed rod 10.

[0018] The bidirectional threaded rod 13 is rotatably connected to the inside of the working platform 1. The working platform 1 has a moving groove at the position corresponding to the moving block 14. The outer side of the moving block 14 is in contact with the inner wall of the moving groove to ensure the stability of the moving block 14 and prevent the moving block 14 from shaking when moving, thereby ensuring the movement of the positioning plate 15.

[0019] The cross-section of slider 9 is T-shaped, which facilitates the movement of rack 10 and prevents rack 10 from falling off.

[0020] When ribbon-like materials need to be cut, the ribbon-like material is placed between two positioning rollers 6. Then, the motor 7 is turned on, driving the positioning rollers 6 to rotate, thus moving the ribbon-like material. After the ribbon-like material is moved to the appropriate position, the electric telescopic rod 3 at the top of the mounting frame 2 is activated. The electric telescopic rod 3 extends, causing the mounting plate 4 to move downwards. Simultaneously, the mounting plate 4 moves the ultrasonic cutting blade 5 at the bottom and the connecting rod 8 at one end downwards, so that the ultrasonic cutting blade 5 contacts the ribbon-like material and cuts it. At this time, the connecting rod 8 moves... The movement of the rack 10 causes the rack 10 to move. Since the rack 10 meshes with the gear 12, the movement of the rack 10 causes the gear 12 to rotate. The rotation of the gear 12 causes the double-threaded rod 13 to rotate. The moving block 14 on the outside of the double-threaded rod 13 slides towards each other along the moving groove of the working platform 1 due to the threaded connection. The moving block 14 causes the top positioning plate 15 to approach the ribbon material until the positioning plate 15 is in contact with both sides of the ribbon material, positioning the two ends of the ribbon material to ensure the stability of the ribbon material cutting and thus ensure the accuracy of the ribbon material cutting. After cutting, the electric telescopic rod 3 shortens, causing the mounting plate 4, ultrasonic cutting blade 5, and connecting rod 8 to move upwards. The positioning plate 15 moves away from the ribbon material, and the ribbon material continues to be conveyed by the positioning roller 6, which facilitates continuous cutting of the ribbon material and improves the accuracy of cutting the ribbon material. Personnel can also adjust the position of the toothed rod 10. After adjusting the toothed rod 10 to a suitable position, personnel can fix it with the fixing screw 11, thereby adjusting the distance between the two positioning plates 15, which is convenient for cutting ribbon materials of different widths and expands the applicability of the cutting device.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
