Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, specifically to a novel ultrasonic fabric cutting machine. Background Technology

[0002] Ultrasonic cutting is a tool that uses the high-frequency energy generated by ultrasonic vibration to cut materials. Its principle is to use the high-frequency energy generated by ultrasonic vibration to transmit it to the blade, causing the blade to vibrate at high frequency, thereby achieving the cutting of materials.

[0003] Patent document CN217026447U discloses an ultrasonic cutting device, which includes an L-shaped support base, an ultrasonic transducer assembly, a tool head, a circular blade, and a bracket. The ultrasonic transducer assembly is inserted through the bottom end of the support base, and the tool head is located at the top end of the ultrasonic transducer assembly. The top end of the support base is adjustablely connected to the bracket, and the end of the bracket away from the support base is movably connected to the circular blade. The circular blade abuts against the tool head, and a piece of fabric is placed between the circular blade and the tool head. The circular blade rotates to cut the fabric into strips. This ultrasonic cutting device is connected to a work platform through a fourth connection hole, and an aviation plug is connected to the power supply of the ultrasonic transducer. Fabric such as woven cloth is placed between the blade and the wedge-shaped surface, the power is turned on, and the cut strips of fabric are fed through a second notch.

[0004] Patent document CN221064858U discloses an ultrasonic-based fabric cutting device, including a base, a circular support platform, an ultrasonic generator, a transducer, a cylinder, a cutting blade, and a cutting blade connecting plate. The circular support platform is fixed on the base and has a circular through hole. The ultrasonic generator passes through the circular through hole and is fixedly installed. The transducer is located at the end of the ultrasonic generator. A cylinder is fixedly installed on the base below the transducer. A moving plate is provided at the end of the cylinder's telescopic rod. The cutting blade connecting plate is fixedly connected to the moving plate. The cutting blade is fixedly connected to the cutting blade connecting plate through an adapter. The cutting blade can contact the transducer under the action of the cylinder. In use, the entire cutting device is first fixed in a suitable position through the threaded through hole on the base, generally at the fabric inlet position. The cylinder is then activated to move, and the telescopic rod drives the cutting blade to move towards the transducer until contact is made. The ultrasonic generator is activated to produce ultrasonic waves, the transducer begins to vibrate, and the high-frequency energy generated is transmitted to the blade, causing the blade to vibrate at a high frequency, thereby achieving the cutting of the fabric.

[0005] In the technical solutions of the two patent documents mentioned above, the transducer is in direct or indirect contact with the blade of the circular knife. The high-frequency vibration generated by the transducer during operation directly acts on the blade of the circular knife, which can easily damage the blade of the circular knife during the fabric cutting process, thereby reducing the service life of the circular knife. Utility Model Content

[0006] The main purpose of this invention is to provide an ultrasonic fabric cutter that can improve the service life and maintenance cycle of the circular blade.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A novel ultrasonic fabric cutting machine includes a mounting block, on which a transducer is fixed. A transmission rod is fixedly connected to the upper end of the transducer. A support plate is fixed to the mounting block on one side of the transducer. An inverted L-shaped sliding plate is slidably mounted vertically on the upper end of the support plate. The sliding plate is connected to the telescopic end of a telescopic rod fixed to the support plate. A groove is formed at the upper end of the sliding plate. A rotating shaft is rotatably mounted in the groove. A circular blade is rotatably mounted on the rotating shaft. Both sides of the circular blade are ground with conical surfaces. The outer edge of the circular blade between the two conical surfaces forms a cutting edge. The circular blade is located above the transmission rod. A V-shaped groove is machined at the upper end of the transmission rod. A lower groove communicating with the V-shaped groove is formed on the transmission rod below the V-shaped groove. The V-shaped groove and the lower groove form a clearance groove. The lower end of the circular blade is located in the clearance groove. The two inclined groove walls of the V-shaped groove contact the two conical surfaces of the circular blade, respectively.

[0009] Specifically, the mounting block and the support plate are integrally formed.

[0010] Specifically, a plug is installed at the lower end of the transducer, which is electrically connected to the transducer and to the ultrasonic generator.

[0011] Specifically, a slider is fixed on the skateboard, and the slider slides and engages with the vertical groove of the support plate.

[0012] Specifically, a rotating sleeve is fixed at the lower end of the skateboard, and the telescopic end of the telescopic rod is rotatably connected inside the rotating sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The transmission rod is equipped with a relief groove, and the two inclined groove walls of the V-shaped groove of the relief groove contact the two conical surfaces of the circular cutter. When the transmission rod transmits vibration to the circular cutter, it can stagger the cutting edge of the circular cutter, which can avoid damage to the cutting edge of the circular cutter, improve the service life of the circular cutter, and increase the maintenance cycle of the circular cutter.

[0015] 2. After the telescopic rod drives the slide plate upward, the slide block can exit from the vertical groove. The telescopic end of the telescopic rod is connected to the slide plate through a rotating sleeve. After the slide block exits from the vertical groove, the slide plate can rotate, thereby allowing the slide plate and the circular cutter to be misaligned with the transmission rod, making it convenient to replace the transmission rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1-4 As shown, a novel ultrasonic fabric cutter includes a mounting block 1, on which a transducer 3 is fixed. A transmission rod 4 is fixedly connected to the upper end of the transducer 3, and a support plate 2 is fixed on the mounting block 1 on one side of the transducer 3. Specifically, the mounting block 1 and the support plate 2 are integrally formed.

[0024] An inverted L-shaped slide plate 6 is slidably mounted on the upper vertical direction of the support plate 2. Specifically, a slider 9 is fixed on the slide plate 6, and the slider 9 is slidably engaged in the vertical groove of the support plate 2.

[0025] like Figure 2 and Figure 3 As shown, the slide plate 6 is connected to the telescopic end of the telescopic rod 10 fixed on the support plate 2. The upper end of the slide plate 6 is provided with a groove 7. A rotating shaft 8 is rotatably arranged in the groove 7. A circular knife 5 is rotatably arranged on the rotating shaft 8. Both sides of the circular knife 5 are ground with conical surfaces. The outer edge of the circular knife 5 between the two conical surfaces forms a cutting edge. The circular knife 5 is located above the transmission rod 4.

[0026] The upper end of the transmission rod 4 is machined with a V-shaped groove 13, and a lower groove 14 communicating with it is opened on the transmission rod 4 below the V-shaped groove 13. The V-shaped groove 13 and the lower groove 14 form a relief groove. The lower end of the circular cutter 5 is located in the relief groove, and the two inclined groove walls of the V-shaped groove 13 are in contact with the two conical surfaces of the circular cutter 5 respectively.

[0027] A plug 12 is installed at the lower end of the transducer 3. The plug 12 is electrically connected to the transducer 3 and to the ultrasonic generator.

[0028] The ultrasonic generator is activated to produce ultrasonic waves, which cause the transducer 3 and the transmission rod 4 to vibrate. The high-frequency energy generated is transmitted to the circular blade 5, causing the circular blade 5 to vibrate at a high frequency, thereby achieving the cutting of the fabric.

[0029] Because the transmission rod 4 is provided with a relief groove, and the two inclined groove walls of the V-shaped groove 13 of the relief groove are in contact with the two conical surfaces of the circular cutter 5, the transmission rod 4 can stagger the cutting edge of the circular cutter 5 when transmitting vibration to the circular cutter 5, which can avoid damage to the cutting edge of the circular cutter 5, improve the service life of the circular cutter 5, and increase the maintenance cycle of the circular cutter 5.

[0030] Example 2: Based on Example 1, referring to... Figure 5 As shown, a rotating sleeve 11 is fixed to the lower end of the slide plate 6, and the telescopic end of the telescopic rod 10 is rotatably connected inside the rotating sleeve 11.

[0031] After the telescopic rod 10 drives the slide plate 6 upward, the slider 9 can exit from the vertical groove. The telescopic end of the telescopic rod 10 is rotatably connected to the slide plate 6 through the rotating sleeve 11. After the slider 9 exits from the vertical groove, the slide plate 6 can rotate, thereby allowing the slide plate 6 and the circular knife 5 to be misaligned with the transmission rod 4, making it convenient to replace the transmission rod 4.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
