[0028] Embodiment 1

[0029] like Figure 1 As shown, this embodiment provides a cutting and fusing device for cutting and fusing a cloth tape, which can be a waistband of underwear or a waistband of other clothing. The cutting and fusing device includes an ultrasonic vibration component 2, a cutting component 1, a control component and an elastic component. Among them, the ultrasonic vibration component 2 is arranged opposite to the cutting component 1, the ultrasonic vibration component 2 can be on the top and the cutting component 1 can be on the bottom; or the ultrasonic vibration component 2 can be on the bottom and the cutting component 1 can be on the top, without position limitation. In this embodiment, the cutting component 1 is on the top and the ultrasonic vibration component 2 is on the bottom. The control component is connected to the cutting component 1, and the control component is used to control the cutting component 1 to move in a direction away from the ultrasonic vibration component 2. The control component can be connected to the cutting component 1 by wire, or it can be connected to the cutting component 1 by wireless connection such as Bluetooth. The cloth tape is arranged between the ultrasonic vibration component 2 and the cutting component 1, and the cutting component 1 is used to squeeze the cloth tape close to the ultrasonic vibration component 2, so that the cloth tape is in a clamped state. Subsequently, the ultrasonic vibration component 2 vibrates at a high frequency, and the temperature of the clamping point between the ultrasonic vibration component 2 and the cloth tape increases due to the high-frequency vibration. When a relatively high temperature is reached, the cloth tape at the clamping position gradually melts, and then the cutting assembly 1 is used to cut the cloth tape, and the cut portion of the cloth tape in a molten state automatically fuses to form a closed loop tape.

[0030] like Figure 2 and Figure 3As shown, in some feasible embodiments, the cutting assembly 1 includes a fixed bracket 17, a driving cylinder 11, a knife seat 12 and a cutter 13. Among them, the driving cylinder 11 is arranged on the fixed bracket 17, and the fixed bracket 17 can be a seven-shaped structure, and the driving cylinder 11 is arranged on the top of the seven-shaped structure. The cutter 13 is detachably connected to the knife seat 12, and the cutter 13 can be fixed to the knife seat 12 with screws, which is convenient for the later maintenance or replacement of the cutter 13. The driving cylinder 11 of this embodiment is only used to drive the knife seat 12 to move in a direction away from the ultrasonic vibration assembly 2.

[0031] like Figure 5 As shown, in some feasible embodiments, the blade 13c of the cutter 13 is not only used to cooperate with the ultrasonic vibration component 2 to cut the cloth tape, but also used to assist in fusing the cut portion of the cloth tape. The end of the cutter 13 includes a first bevel 13a and a second bevel 13b, the angle of the first bevel 13a can be 5°-30°, and the angle of the second bevel 13b can be 45°-60°. The second bevel 13b is greater than the first bevel 13a, and the intersection of the first bevel 13a and the second bevel 13b forms a blade 13c. In the process of extruding the cloth tape, the blade 13c plays a major extrusion role, and the first bevel 13a can assist in extruding the cloth tape. In order to increase the contact area between the first bevel 13a and the cloth tape, the angle of the first bevel 13a cannot be set too large to facilitate the fusion of the cut portion of the auxiliary cloth tape.

[0032] Please continue reading Figure 3 In some feasible embodiments, the elastic component includes a limiting mechanism and an elastic member, one end of the elastic member is connected to the limiting mechanism, and the other end of the elastic member is connected to the knife seat 12. The elastic member can be a spring 16, or other elastic parts that can be retracted and deformed. The elastic member of this embodiment is a spring 16, and the two ends of the spring 16 are respectively connected to the limiting mechanism and the knife seat 12. The position of the limiting mechanism remains unchanged, and the length of the spring 16 can be set longer. During use, the spring 16 is always in a compressed state, and the spring 16 pre-recovers and applies a fixed force toward the ultrasonic vibration component 2 to the knife seat 12, thereby driving the cutter 13 on the knife seat 12 to cut the cloth tape. Since the positions of the limiting mechanism and the ultrasonic vibration component 2 are unchanged, when the cutter 13 cuts the cloth tape each time, the travel of the spring 16 is consistent, so the spring 16 can apply a fixed force to the cloth tape, so that the force of the cutter 13 on the cloth tape is consistent each time, and the cutting stability is maintained. The conventional cutter 13 is driven by the driving cylinder 11 to exert a force on the fabric tape. The driving cylinder 11 is sometimes prone to unstable air pressure, resulting in insufficient force exerted by the driving cylinder 11 on the fabric tape, and the fabric tape cannot be cut. The cutter 13 of the present application is driven by the spring 16 to exert a fixed force on the fabric tape, and the cutting is stable.

[0033] Furthermore, the limiting mechanism includes a limiting plate 14 and a plurality of adjusting screw groups, a spring 16 is fixed on the limiting plate 14, and the plurality of adjusting screw groups are used to adjust the height of the limiting plate 14 to adjust the fixing force of the elastic member on the tool holder 12. Specifically, the adjusting screw group includes an adjusting screw 15 and a plurality of nuts. During installation, a nut is first screwed onto the adjusting screw 15. A through hole corresponding to the position of the adjusting screw 15 is provided on the limiting plate 14. The limiting plate 14 is sleeved on the adjusting screw 15 through the through hole. The top of the limiting plate 14 abuts against the above-mentioned installed nut, and then another nut is screwed in to abut against the bottom of the limiting plate 14 to complete the installation of the limiting plate 14. In addition, the positions of the nuts on the upper and lower sides of the limiting plate 14 can be adjusted to adjust the height of the limiting plate 14.

[0034] During use, if it is necessary to increase the fixing force of the cutter 13 on the cloth belt, the two nuts on the screw 15 can be adjusted to fix the limit plate 14 close to the cloth belt. The greater the compression of the spring 16 during operation, the greater the fixing force on the knife seat 12, thereby making the fixing force of the cutter 13 on the cloth belt greater. Conversely, if it is necessary to reduce the fixing force of the cutter 13 on the cloth belt, the nuts can be adjusted to fix the limit plate 14 away from the cloth belt.

[0035] In order to make the cutter 13 cut the cloth tape more stably, one or more guide mechanisms may be provided on the fixed bracket 17, and the guide mechanisms are used to make the knife holder 12 move stably along a fixed direction, thereby making the cutter 13 move stably along the fixed direction.

[0036] In some feasible embodiments, the guide mechanism includes a guide cylinder 18 and a guide rod 19, one end of the guide rod 19 is disposed in the guide cylinder 18, and the other end of the guide rod 19 away from the guide cylinder 18 is connected to the knife seat 12. The diameter of the guide rod 19 can be set to be equal to the inner diameter of the guide cylinder 18. During operation, the knife seat 12 can move along the radial direction of the guide cylinder 18 through the guide rod 19, so that the cutter 13 moves along the radial direction of the guide cylinder 18, stably cutting the cloth tape and improving the stability of the operation.

[0037] In some feasible embodiments, the guide cylinder 18 is arranged on the fixed bracket 17, and two or more guide cylinders 18, guide rods 19 and springs 16 can be provided. In this embodiment, two guide cylinders 18, guide rods 19 and springs 16 are provided respectively. One end of the two guide rods 19 is fixedly connected to the knife seat 12, and the other end extends into the corresponding guide cylinder 18. The two springs 16 are respectively sleeved on the corresponding guide rods 19, and the two ends of the springs 16 can abut against the knife seat 12 and the limit plate 14, or can be fixedly connected to the knife seat 12 and the limit plate 14 by welding or other methods.

[0038] The power of the knife holder 12 comes from the driving cylinder 11. The driving cylinder 11 of this embodiment can be provided with only one air inlet. When the cutter 13 has finished cutting the cloth tape, the air inlet is controlled to be inletted, and the driving cylinder 11 drives the knife holder 12 to move in a direction away from the cloth tape, lifts the cutter 13, and compresses the spring 16. When the cutter 13 needs to cut the cloth tape, the air inlet is controlled to be deflated, and the driving cylinder 11 does not apply force to the knife holder 12. The knife holder 12 moves toward the cloth tape under the action of the spring 16 to cut the cloth tape. The cycle is repeated successively to complete multiple cuts.

[0039] In some feasible embodiments, the control component can control the operation of the cutting component 1 in a wired manner or in a wireless manner. The control component of this embodiment includes a foot switch 3 and a relay, and the foot switch 3 is connected to the drive cylinder 11 through the relay. Specifically, a switch button is provided at the bottom of the pedal of the foot switch 3. During use, stepping on the pedal with your foot can trigger the switch button response. The switch button causes the drive cylinder 11 to start deflation through the relay, and the spring 16 drives the knife seat 12 to move toward the ultrasonic vibration component 2 to cut the cloth tape. When the pedal is released, the drive cylinder 11 is automatically inflated, driving the knife seat 12 to move in a direction away from the cloth tape, and lifting the cutter 13.

[0040] Since different types of cloth tapes have different thicknesses, in order to adapt to cloth tapes of different thicknesses, the height of the limiting plate 14 can be adjusted, thereby adjusting the fixing force of the spring 16 on the cloth tape.

[0041] In some other feasible embodiments, the control component can also be wirelessly connected to the driving cylinder 11. Specifically, the control component includes a remote controller, and both the remote controller and the driving cylinder 11 are provided with a wireless module such as a Bluetooth module or WIFI, and the remote controller and the driving cylinder 11 establish a wireless connection through the Bluetooth module. The user can control the driving cylinder 11 to drive the cutter 13 to cut the cloth tape by operating the remote controller.

[0042] like Figure 2 and Figure 4 As shown, in some feasible embodiments, the ultrasonic vibration assembly 2 includes an ultrasonic transducer 21 and a vibration head 22 connected to each other, and the ultrasonic transducer 21 can drive the vibration head 22 to vibrate at a high frequency. The end of the vibration head 22 in contact with the cloth tape is a flat surface, which is convenient for placing the cloth tape. The vibration head 22 and the cutting assembly 1 squeeze the cloth tape together to cut and fuse the cloth tape. The ultrasonic transducer 21 is also connected to a control switch 4, and the user can operate the control switch 4 to control the ultrasonic transducer 21 to switch between on and off.

[0043] In some feasible embodiments, the ultrasonic transducer 21 is connected to the limit screw 23 through the fixing plate 24, and two, three or more limit screws 23 can be provided. In this embodiment, four limit screws 23 are provided, and the limit screws 23 are used to adjust the distance between the vibration head 22 and the cutting assembly 1. Figure 4 It can be seen that the ultrasonic transducer 21 is fixed on the fixing plate 24, and a limiting screw is threadedly connected to the limiting screw 23. The height of the ultrasonic transducer 21 can be adjusted by adjusting the limiting screw to adjust the distance of the vibration head 22 relative to the cutter 13 to adapt to various cloth tapes of different thicknesses.

[0044] The working process of this embodiment is as follows: first adjust the four limit screws 23 and the three adjustment screws 15 so that the cutter 13 maintains a suitable distance relative to the vibration head 22, which is suitable for cutting the cloth tape. Pass the double-layer cloth tape between the vibration head 22 and the cutter 13 (the passing end of the cloth tape is closed). The passing length can be set by yourself. If the passing length is 10cm, the length of the finished product is 20cm; if the passing length is 15cm, the length of the finished product is 30cm. After the cloth tape is passed through, step on the foot switch 3 with your foot to drive the cylinder 11 to deflate, driving the cutter 13 to squeeze the cloth tape against the vibration head 22. Then start the control switch 4 to start the ultrasonic transducer 21 to work, the vibration head 22 vibrates at a high frequency, and cooperates with the cutter 13 to cut the cloth tape, and at the same time, the cut part of the cloth tape is fused and closed.
