Technical Field

[0001] This utility model relates to the field of rubber band machine technology, specifically to an ultrasonic cutter assembly for a high-speed automatic splicing rubber band machine. Background Technology

[0002] The high-speed automatic splicing elastic band machine is a highly specialized textile finishing equipment, mainly used in the manufacture of products that require elastic bands, such as underwear, sportswear, masks, and medical protective clothing. It is a machine that can automatically, quickly, and accurately splice the joints of two elastic bands together. The ultrasonic cutting component of the high-speed automatic splicing elastic band machine is used to cut off the excess part of the elastic band.

[0003] The existing ultrasonic cutter assembly has the following problems: The cutting head of the existing ultrasonic cutter assembly is a consumable part. The cutting edge will wear down after long-term use, resulting in poor cutting effect. It needs to be sharpened or replaced regularly. However, most of the existing cutting heads are fixed with bolts, which makes disassembly and assembly inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic cutter assembly for a high-speed automatic splicing rubber band machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic cutter assembly for a high-speed automatic splicing rubber band machine, comprising a transducer, a mounting plate fixed on the surface of the transducer, an amplitude transformer rod on the transducer, a cutter head on the amplitude transformer rod, a docking structure on the amplitude transformer rod, the docking structure comprising a rotating component, a rotating component connected in the amplitude transformer rod, a rotating clamping block on the rotating component, a rotating block on the rotating component, a locking slot in the rotating block, a locking post connected in the amplitude transformer rod, a spring fixed in the locking post, a limit rod connected to the spring, a handle on the limit rod, a connecting block on the surface of the cutter head, and a docking plate fixed on the connecting block.

[0006] Preferably, the surface of the connecting block is provided with insert rods, and at least two insert rods are provided, which are symmetrically arranged on the surface of the connecting block.

[0007] Preferably, an elastic connector is fixed inside the amplitude transformer, and a clamping plate is provided at the end of the elastic connector.

[0008] Preferably, when the elastic connector is in its unstressed, natural state, the clamping plate unfolds outward.

[0009] Preferably, the surface of the docking plate is provided with anti-slip texture.

[0010] Preferably, a fixing block is fixed inside the amplitude rod, and the rotating component passes through the middle of the fixing block.

[0011] Preferably, a limiting groove is provided inside the fixed block, and a limiting slide rod is provided on the surface of the rotating component.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When installing the cutter head, insert the mating plate into the amplitude transformer rod. Rotating the rotating component drives the rotating clamping block to rotate. After the rotating clamping block rotates, it pushes against the clamping plate. Then, the rotating clamping block and the clamping plate together press and tighten the mating plate. Under the action of friction, the mating plate is limited. Then, rotate the locking pin to turn it into the locking slot. Under the action of the spring, the limiting rod is inserted into the amplitude transformer rod, which realizes the limitation of the rotating component and completes the installation of the cutter head, achieving the beneficial effect of convenient installation. When disassembling, slide the limiting rod by the handle to release the limitation of the locking pin, and then rotate the rotating component so that the rotating clamping block does not clamp the mating plate. This achieves the beneficial effect of convenient disassembly and assembly of the cutter head when it needs to be disassembled and maintained. Attached Figure Description

Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides an ultrasonic cutter assembly for a high-speed automatic splicing rubber band machine, including a transducer 1, a mounting plate 2 fixed on the surface of the transducer 1, an amplitude transformer 3 on the transducer 1, a cutter head 4 on the amplitude transformer 3, and a docking structure 5 on the amplitude transformer 3.

[0017] Specifically, the cutter head 4 is connected to the amplitude transformer 3 via the docking structure 5, and the transducer 1 is fixed on the frame via the mounting plate 2. The transducer 1 is responsible for converting electrical energy into mechanical vibration, and then transmitting ultrasonic vibration to the cutter head 4 via the amplitude transformer 3. The cutter head 4 cuts by rubbing the rubber band with ultrasonic vibration.

[0018] Please see Figure 3 and Figure 4 This utility model provides an ultrasonic cutter assembly for a high-speed automatic splicing rubber band machine. The docking structure 5 includes a rotating component 51. The rotating component 51 is rotatably connected to the amplitude rod 3. A rotating clamping block 52 is fixed on the rotating component 51. The surface of the rotating clamping block 52 is inclined. A rotating block 53 is fixed on the rotating component 51. A locking slot 54 is opened in the rotating block 53.

[0019] A locking post 55 is rotatably connected to the luffing rod 3. The locking post 55 can be rotated into the locking port 54. A spring 56 is fixed in the locking post 55. A limit rod 57 is connected to the spring 56. The limit rod 57 can be inserted into the luffing rod 3 to limit the locking post 55. A handle 58 is provided on the limit rod 57.

[0020] The cutter head 4 has a connecting block 59 integrally formed on its surface. A docking plate 510 is fixed on the connecting block 59. The surface of the docking plate 510 is provided with anti-slip texture 514, which has an anti-slip effect and improves the stability of the fastening. The surface of the connecting block 59 is provided with two insertion rods 511, which are symmetrically arranged on the surface of the connecting block 59. Of course, three or four insertion rods can also be provided, which is not limited here. They are used for quick alignment and docking. After docking, the insertion rods 511 limit the movement and prevent leakage and shaking.

[0021] Among them, the variable amplitude rod 3 has an elastic connector 512 fixed inside. The end of the elastic connector 512 is provided with a pressure plate 513. When the elastic connector 512 is in a natural state without force, the pressure plate 513 unfolds outward, which has the beneficial effect of high fastening firmness and high stability when it is pressed to limit the position of the docking plate 510.

[0022] The variable amplitude rod 3 has a fixed block 515 inside, and the rotating part 51 passes through the middle of the fixed block 515, which ensures the high stability of the rotation of the rotating part 51 and prevents deformation under force. The fixed block 515 has a limit groove 516 inside, and the rotating part 51 has a limit rod 517 on its surface, which is used to limit the rotation.

[0023] Specifically, when installing the cutter head 4, insert the mating plate 510 into the amplitude transformer 3, so that the mating plate 510 is located between the clamping plates 513. Then, rotate the rotating component 51 to drive the rotating clamping block 52 to rotate. After the rotating clamping block 52 rotates, it will push the clamping plate 513. Then, the rotating clamping block 52 and the clamping plate 513 will press and tighten the mating plate 510 together. Under the action of friction, the mating plate 510 is limited. Then, rotate the locking pin 55 to turn it into the locking slot 54. Under the action of the spring 56, the limiting rod 57 is inserted into the amplitude transformer 3, realizing the limiting of the rotating component 51 and completing the installation of the cutter head 4. This achieves the beneficial effect of convenient installation. When disassembling, slide the limiting rod 57 through the handle 58 to release the limiting of the locking pin 55. Then rotate the rotating component 51 so that the rotating clamping block 52 does not clamp the mating plate 510. This achieves the beneficial effect of convenient disassembly and assembly of the cutter head 4 when it needs to be disassembled and maintained.
