Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to an ultrasonic cutting knife. Background Technology

[0002] An ultrasonic cutter is an ultrasonic device specifically designed for cutting. It is an important category of ultrasonic applications. Its principle is completely different from traditional cutting. The ultrasonic cutter uses a transducer to convert electrical energy into mechanical energy, generating high-frequency oscillations, thereby achieving the cutting of materials such as plastics.

[0003] However, in actual operation, existing ultrasonic cutter handles have some obvious defects. Due to their design limitations, operators often exert too much downward force when holding the handle for cutting operations, causing it to slip off. Once the handle slips off, the operator's fingers may directly touch the high-speed vibrating blade, resulting in a serious cut. Moreover, holding the handle for a long time can cause sweaty hands, leading to slippage and creating a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide an ultrasonic cutting knife to solve the technical problem that the handle of the ultrasonic cutting knife in the prior art is not easy to hold, and is prone to falling off or slipping, which leads to safety hazards.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] An ultrasonic cutting tool, comprising:

[0007] The housing has a grip and a neck on its outer periphery near the tip end, with at least a portion of the neck recessed inward along its radial direction to form an anti-slip groove.

[0008] The cutting tool includes a transducer, a blade, and a shock absorber. The transducer is disposed within the housing, the shock absorber is disposed on the transducer, and the blade is detachably connected to the transducer and protrudes from the blade tip end of the housing.

[0009] Preferably, the outer periphery of the grip portion is provided with an anti-slip mechanism.

[0010] Preferably, the anti-slip mechanism is dot-shaped protrusions and / or stripe-shaped protrusions.

[0011] Preferably, the anti-slip groove has rounded corners inside, and / or the connection between the anti-slip groove and the neck has rounded corners.

[0012] Preferably, in the direction from the neck to the tip of the blade, the depth of at least a portion of the anti-slip groove gradually increases and then gradually decreases.

[0013] Preferably, the grip portion is integrally formed with the housing.

[0014] Preferably, the grip portion is detachably connected to the housing.

[0015] Preferably, the shock-absorbing component is a flexible sleeve, which is fitted around the outer periphery of the transducer and abuts against the inner wall of the housing.

[0016] Preferably, a heat dissipation hole is provided on the neck, and the heat dissipation hole connects the inside of the shell to the outside.

[0017] Preferably, the housing includes a front shell and a rear shell, which are interlocked and detachably connected.

[0018] The beneficial effects of this utility model are:

[0019] The ultrasonic cutter proposed in this invention improves the stability and reliability of the operator's grip by incorporating a handle and a neck on the outer periphery of the housing near the blade tip, with an anti-slip groove on the neck. When the operator grips the cutter firmly, the palm and fingers bend and close to hold the handle, with the fingertips engaging in the anti-slip groove, effectively increasing friction and reducing the risk of the handle slipping during exertion. This prevents fingers from touching the blade and causing cuts, ensuring the operator's safety. Furthermore, the transducer, blade, and shock absorber ensure the cutter's normal operation, and the detachable blade facilitates replacement and maintenance, extending the cutter's lifespan.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 3 The ultrasonic cutting knife provided in this embodiment of the utility model includes a housing 1 and a cutting tool 2. The housing 1 has a gripping portion 13 and a neck 14 arranged along its own axial direction on the outer periphery near the cutting head end 10. At least a portion of the neck 14 is recessed inward along its own radial direction to form an anti-slip groove 141. The cutting tool 2 includes a transducer 21, a blade 22, and a shock absorber 23. The transducer 21 is disposed inside the housing 1, the shock absorber 23 is disposed on the transducer 21, and the blade 22 is detachably connected to the transducer 21 and protrudes from the cutting head end 10 of the housing 1.

[0032] The ultrasonic cutter proposed in this utility model improves the stability and reliability of the operator's grip by providing a grip portion 13 and a neck 14 on the outer periphery of the housing 1 near the blade tip 10, and providing an anti-slip groove 141 on the neck 14. When the operator grips the cutter forcefully, the palm and fingers bend and close to hold the grip portion 13, and the corresponding fingertips engage in the anti-slip groove 141, which effectively increases friction and reduces the risk of the handle slipping, thereby avoiding the danger of fingers touching the blade 22 and causing cuts, and ensuring the operator's personal safety. In addition, the reasonable arrangement of the transducer 21, blade 22 and shock absorber 23 ensures the normal operation of the cutter, and the detachable blade 22 facilitates replacement and maintenance, extending the service life of the cutter.

[0033] The transducer 21 is a common device in this field, and its working principle and specific structure will not be described in detail here.

[0034] The specific structure of the ultrasonic cutting tool is described below.

[0035] Regarding housing 1: Housing 1 includes a front housing 11 and a rear housing 12. The front housing 11 and the rear housing 12 are interlocked and detachably connected, making the assembly and disassembly of the ultrasonic cutting blade more convenient. During production, this facilitates the installation and debugging of various components, improving production efficiency. Furthermore, the detachable design allows for easy opening of housing 1 for repair and replacement when internal components such as the blade 2, transducer 21, or shock absorber 23 malfunction or require maintenance, reducing maintenance costs and difficulty. Specifically, the front housing 11 and the rear housing 12 can be connected by bolts, snap-fit ​​connections, etc., which will not be elaborated upon here.

[0036] In other embodiments, the housing 1 may also be integrally formed or composed of three or four parts, etc., which is not limited here.

[0037] The cutting tool 2 is placed inside the housing 1. The cutting tool 2 also includes a control unit 24, which is connected to the transducer 21 via signal, making the operation of the ultrasonic cutting tool more intelligent and automated. Operators can set cutting modes and parameters through preset programs or operating interfaces to achieve precise control of the working state of the transducer 21, flexibly adjust the working frequency, power and other parameters of the transducer 21 to adapt to different materials and cutting needs, thereby improving the quality and efficiency of cutting.

[0038] Specifically, the control unit 24 can be an existing drive board or control board, which are all existing electrical devices in the field. Their working principle and specific structure will not be described in detail here.

[0039] In addition, the housing 1 is equipped with a button 25 and an indicator light 26. Both the button 25 and the indicator light 26 are connected to the control unit 24. The button 25 allows the operator to directly adjust and set the working mode and parameters of the cutting blade without the need for other external equipment, thus improving the convenience and efficiency of operation. The indicator light 26 provides intuitive feedback to the operator on the working status of the cutting blade, such as whether the power is on, whether the working mode is normal, or whether it is in a fault state. The operator can quickly obtain relevant information through the color and flashing frequency of the indicator light 26, and take appropriate action in a timely manner to avoid misoperation or work delays caused by a lack of understanding of the equipment status.

[0040] Because the transducer 21 generates high-frequency vibrations during operation, if these vibrations are directly transmitted to the housing 1, it will cause severe vibration of the entire ultrasonic cutting blade, affecting the operator's grip and control, and reducing the cutting accuracy and stability. Therefore, the transducer 21 is equipped with a shock absorber 23 to absorb and buffer most of the vibrations, reducing the vibration energy transmitted to the housing 1. Specifically, the shock absorber 23 is a flexible sleeve, which is fitted around the outer periphery of the transducer 21 and abuts against the inner wall of the housing 1. This reduces the transmission of vibration to the housing 1, lowers the overall vibration amplitude of the cutting blade during operation, improves operational stability and comfort, and reduces operator hand fatigue. In addition, the flexible sleeve provides some protection for the transducer 21, reducing damage from external impacts and collisions, and extending the service life of the transducer 21. Because the flexible sleeve abuts against the inner wall of the housing 1, it increases the contact area and friction between the transducer 21 and the housing 1, making the installation of the transducer 21 within the housing 1 more stable, less prone to displacement or loosening, and ensuring the reliability and accuracy of the cutting blade. Specifically, flexible sleeves can be made of rubber, silicone, etc., which will not be elaborated here.

[0041] In other embodiments, the shock absorber 23 can also be selected from spring shock absorbers, shock-absorbing air cushions, viscoelastic damping materials, etc. There is no limitation on its specific form, as long as it can achieve the shock absorption effect of transducer 21.

[0042] In actual use, the operator needs to hold the grip portion 13 of the housing 1 for cutting operations. To further improve the anti-slip effect of the housing 1, an anti-slip mechanism 131 is provided on the outer periphery of the grip portion 13. The anti-slip mechanism 131 can increase the friction between the hand and the grip portion 13. When the operator is working with the housing 1, even if the hands are sweaty or contaminated with oil, it can effectively prevent the hands from slipping, ensuring the stability and safety of the operation.

[0043] Specifically, the anti-slip mechanism 131 consists of dot-shaped and / or striped protrusions, providing multi-point contact and directional friction. The dot-shaped protrusions increase resistance in different directions, while the striped protrusions provide better grip guidance in specific directions, further enhancing the anti-slip effect and effectively preventing the knife 2 from slipping during use. The design of multiple protrusions in the anti-slip mechanism 131 increases the surface roughness of the grip 13, resulting in a tighter and more stable contact between the hand and the grip 13, maintaining good anti-slip performance in both dry and humid environments.

[0044] Specifically, the anti-slip mechanism 131 can be composed of evenly distributed dot-shaped protrusions, which are hemispherical in shape and distributed multiple times on the outer periphery of the grip portion 13. Alternatively, the anti-slip mechanism 131 can be composed of striped protrusions, which are distributed along the axial direction of the grip portion 13 and are parallel to each other in the circumferential direction. A hybrid anti-slip mechanism 131 can also be used, where dot-shaped and striped protrusions are simultaneously provided on the outer periphery of the grip portion 13, and distributed in a spiral pattern along the circumferential direction of the grip portion 13.

[0045] In other embodiments, the anti-slip mechanism 131 may also be a rhomboid protrusion, a corrugated protrusion, or an irregular protrusion, etc., which is not limited here.

[0046] Regarding the connection between the grip 13 and the housing 1, the grip 13 and the housing 1 are integrally molded, which ensures the strength and stability of the overall structure. There are no issues such as loosening, gaps, or breakage that may occur at the connection points, thus improving the durability of the housing 1 and reducing maintenance costs and usage risks caused by connection point failures. Furthermore, the integrated structure makes the appearance of the housing 1 simpler and smoother, without obvious splicing marks, enhancing the product's aesthetics.

[0047] The anti-slip groove 141 is designed to engage the user's fingers, facilitating grip and force application. To further enhance user comfort, the anti-slip groove 141 has rounded corners inside, and / or, the connection between the anti-slip groove 141 and the neck 14 has rounded corners. The rounded corners inside the anti-slip groove 141 reduce sharp edges. This prevents discomfort or even scratches caused by fingers contacting sharp areas inside the anti-slip groove 141, thus improving operational comfort and safety. The rounded corners at the connection between the anti-slip groove 141 and the neck 14 reduce stress concentration. During use, this rounded corner design distributes the force, reducing fatigue damage caused by stress concentration at the connection and extending the handle's lifespan.

[0048] Specifically, from the neck 14 to the blade tip 10, the depth of at least part of the anti-slip groove 141 gradually increases and then gradually decreases, better adapting to the natural force and positional changes of the hand during grip. Near the neck 14, the gradually increasing depth of the anti-slip groove 141 provides a stronger anti-slip effect, effectively preventing hand slippage during initial grip. As it moves towards the blade tip 10, the depth of the anti-slip groove 141 gradually decreases, reducing restrictions on finger movement and allowing the operator to more flexibly adjust the position and angle of their fingers when performing precise cutting operations, improving operational accuracy and dexterity.

[0049] Regarding the connection method between the neck 14 and the shell 1, the neck 14 and the shell 1 can be integrally molded, ensuring structural integrity and consistency, reducing potential gaps, loosening, or deformation at the connection point, and enhancing the overall strength and durability of the shell 1. Alternatively, the neck 14 and the shell 1 can be detachably connected, facilitating maintenance and replacement. When the neck 14 is damaged or worn, it can be replaced individually without replacing the entire shell 1, saving maintenance costs. Furthermore, the detachable design allows for quick replacement of necks 14 with different functions or characteristics according to different usage needs or scenarios, such as necks 14 with anti-slip grooves 141 of different sizes and shapes, increasing the product's applicability and flexibility. Specifically, the neck 14 can be machined separately, and after processing, it can be fitted onto the outer periphery of the shell 1. No limitation is placed on the connection method here; it can be chosen adaptably according to actual needs.

[0050] In addition, heat dissipation holes 142 are provided on the neck 14, connecting the interior of the housing 1 to the outside. During the operation of the ultrasonic cutter, components such as the internal transducer 21 generate heat. The heat dissipation holes 142 effectively dissipate the heat generated inside the housing 1 to the outside, preventing components from degrading in performance, being damaged, or having their service life shortened due to overheating, thereby improving the working stability and reliability of the cutter. At the same time, the heat dissipation holes 142 can reduce the temperature inside the housing 1, thereby reducing the discomfort of high temperatures to the operator's hands and improving operating comfort. Specifically, multiple heat dissipation holes 142 are provided, and the multiple heat dissipation holes 142 are arranged at intervals along the circumference of the neck 14.

[0051] Example 2

[0052] Figure 4 Embodiment 2 is shown, wherein components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The differences are as follows:

[0053] The grip 13 is detachably connected to the housing 1, providing users with greater flexibility. When the grip 13 wears out, is damaged, or needs to be replaced according to different users' hand shapes and usage habits, the grip 13 can be easily replaced individually without replacing the entire housing 1, saving costs. Specifically, the grip 13 is configured as a soft rubber sleeve, which is fitted onto the housing 1, and the outer surface of the soft sleeve has an anti-slip mechanism 131.
