Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic tape cutting machines, and particularly relates to an ultrasonic tape cutting machine. Background Art

[0002] There are mainly two tape cutting methods for existing ultrasonic tape cutting machines. One is flat cutting, that is, the cutting knife is driven to move up and down by a cylinder or an electric cylinder, and cooperates with an ultrasonic tool head to cut the strip when the cutting knife moves down to a preset position. The other is roll cutting, that is, through a rotatable roll cutting knife, cooperating with an ultrasonic tool head, when the roll cutting knife rotates to a preset position, the blade on the roll cutting knife cuts the strip. The problem with flat cutting is low efficiency, so in order to improve the tape cutting efficiency, the roll cutting method is generally adopted. However, when cutting strips of different thicknesses by roll cutting, the gap between the roll cutting knife and the ultrasonic tool head and the pressure applied to the strip need to be adjusted accordingly, and there is currently no corresponding mechanism to conveniently achieve this adjustment.

[0035] Embodiment

[0036] Refer to Figure 1 , an embodiment of the present utility model provides an ultrasonic tape cutting machine, which mainly includes a frame 1, an ultrasonic component 2, a tape cutting component 5, a feeding component 15 and a discharge chute 19.

[0037] Refer to Figure 1 , the frame 1 of the ultrasonic tape cutting machine is generally a cuboid, and its top surface forms a table for guiding the strip. In front of the table is a downward-sloping working area, where the ultrasonic component 2, the tape cutting component 5, the feeding component 15 and the discharge chute 19 are arranged. Among them, the working area is separated into the inside and the outside of the frame 1 by a workbench surface, and a notch is formed through the workbench surface. The ultrasonic component 2 is generally located below the notch, and the tape cutting component 5, the feeding component 15 and the discharge chute 19 are located above the notch.

[0038] Refer to Figure 1 and Figure 2 , the frame 1 includes a machine table 12 and two mounting brackets 13; the mounting brackets 13 are fixedly installed on the machine table 12. Specifically, the mounting brackets 13 are fixedly installed on the mounting table surface, and the two mounting brackets 13 are respectively arranged on both sides of the notch on the mounting table surface for installing some components of the tape carrying component and the feeding component 15.

[0039] Refer to Figure 2, The ultrasonic component 2 is installed on the frame 1, which includes an ultrasonic transducer 3 and an ultrasonic tool head 4. The ultrasonic transducer 3 is used to drive the ultrasonic tool head 4 to vibrate. Among them, the ultrasonic transducer 3 mainly includes a piezoelectric ceramic sheet, a front cover plate, a rear cover plate and electrodes; the piezoelectric ceramic sheet is a key component of the ultrasonic transducer 3, which converts electrical energy into mechanical vibration, and usually uses piezoelectric ceramic materials such as lead zirconate titanate (PZT). The front cover plate and the rear cover plate are used to protect the piezoelectric ceramic sheet and transfer the vibration to the tool head. The electrodes are used to provide a high-frequency voltage for the piezoelectric ceramic sheet to make it vibrate. The main function of the ultrasonic transducer 3 is to convert electrical energy into high-frequency mechanical vibration. This vibration is usually between 20 kHz and 40 kHz, enabling the tool head to perform precise and efficient cutting. The ultrasonic tool head 4 mainly includes a horn and a cutting tool head; the horn is connected between the transducer and the tool head, and its function is to adjust the amplitude to make it suitable for cutting applications. The cutting tool head is the component that directly contacts the material and performs the cutting operation; it is usually made of materials such as cemented carbide and titanium alloy to ensure durability and cutting accuracy. The ultrasonic tool head 4 applies pressure to the material through the high-frequency vibration generated by the ultrasonic transducer 3, so as to achieve the effect of cutting or separating. It can provide precise and fast cutting, reducing the physical deformation and thermal influence of the material. The ultrasonic transducer 3 and the ultrasonic tool head 4 work together to convert electrical energy into mechanical vibration, and then perform cutting through high-frequency vibration. This method is particularly suitable for cutting textiles, synthetic materials or thin film materials, because it can provide high-precision, burr-free cuts while reducing the thermal influence of the material.

[0040] Among them, a cutting plane is formed on the topmost surface of the cutting tool head of the ultrasonic tool head 4, and the strip can be positioned on this cutting plane for cutting, and the cutting plane is substantially parallel to the installation table surface.

[0041] Referring to Figure 2 and Figure 3 , The tape cutting assembly 5 is installed on the frame 1, which includes a roller cutter 6, a roller cutting fixed seat 7, a first driving member 8 and a second driving member 9; both ends of the roller cutter 6 are pivotally connected to the two roller cutting fixed seats 7; the two roller cutting fixed seats 7 are located above the ultrasonic tool head 4 and are connected to the output ends of the two first driving members 8; the first driving member 8 is configured to be suitable for driving the corresponding roller cutting fixed seat 7 to move in a manner of approaching or departing from the ultrasonic tool head 4 to adjust the gap between the roller cutter 6 and the ultrasonic tool head 4; the second driving member 9 is configured to be suitable for driving the roller cutter 6 to rotate.

[0042] Among them, the output end of the second driving member 9 has a first spur gear 10, and the end of the roller cutter 6 close to the second driving member 9 has a second spur gear 11; the relative position and tooth depth of the first spur gear 10 and the second spur gear 11 are configured so that the first spur gear 10 and the second spur gear 11 always remain engaged within the gap adjustment range between the roller cutter 6 and the ultrasonic tool head 4.

[0043] The mounting frame 13 is provided with a slide groove 14 suitable for slidingly cooperating with the roller cutting fixed seat 7; the upper end of the slide groove 14 is open to allow the roller cutting fixed seat 7 to enter the slide groove 14; the first driving member 8 is installed on the mounting frame 13.

[0044] Specifically, refer to Figure 2 and Figure 3 The roller cutter 6 is a roller-shaped component, with its ends mounted to the roller cutter holder via bearings. The roller cutter holder 7 is a block-shaped component that forms a sliding fit with the mounting frame 13. The mounting frame 13 is provided with a chute 14 sized to match the roller cutter holder 7. The chute 14 extends perpendicular to the cutting plane formed by the ultrasonic tool head 4 in the ultrasonic assembly 2. The upper end of the chute 14 is open, allowing the roller cutter holder 7 to enter the chute 14 from the upper end during installation. The roller cutter holder 7 can be configured with an I-shaped cross-section to nest on the mounting frame 13 and slide within the chute 14.

[0045] The first driving member 8 is fixedly mounted on the upper end of the mounting frame 13, and its output shaft extends downward and is connected to the roller cutting fixed seat 7. The connection method between the two can be that the output shaft of the first driving member 8 is directly screwed to the roller cutting fixed seat 7, or the output shaft can be inserted into the roller cutting fixed seat 7 and then locked by bolts, or directly welded, etc.

[0046] The second driving member 9 is mounted and fixed on the mounting table, and a first spur gear 10 is mounted on its output shaft. At the same time, a second spur gear 11 is also provided at one end of the roller cutter 6. The tooth surfaces of the first spur gear 10 and the second spur gear 11 face each other and can mesh with each other. Among them, the first spur gear 10 and the second spur gear 11 have the deepest meshing degree at a certain position. Thereafter, as the roller cutter fixed base moves up or down, the meshing degree of the first spur gear 10 and the second spur gear 11 will decrease. However, the tooth depth of the first spur gear 10 and the second spur gear 11 is deep enough so that the two can still maintain meshing in this situation.

[0047] During use, if it is necessary to adjust the gap between the roller cutter 6 and the ultrasonic tool head 4, the first driving member 8 can be controlled to operate, so that the output shaft of the first driving member 8 is extended or shortened, driving the roller cutting fixed seat 7 closer to or away from the ultrasonic tool head 4, thereby adjusting the gap between the roller cutter 6 and the ultrasonic tool head 4.

[0048] Since the gap between the roller cutter 6 and the ultrasonic tool head 4 can be adjusted, and the roller cutter 6 needs to be connected to the second driving member 9 to achieve rotation. If a conventional bevel gear matching method is adopted, then after the position of the roller cutter 6 changes, the bevel gear matching relationship will be damaged. Therefore, in this technical solution, a first spur gear 10 and a second spur gear 11 are provided, and a meshing relationship is formed between the two. In this way, when the position of the roller cutter 6 changes, the second spur gear 11 on the roller cutter 6 will still remain meshed with the first spur gear 10 on the second driving member 9, enabling the second driving member 9 to drive the roller cutter 6 to rotate.

[0049] The first driving member 8 is a cylinder or an electric cylinder, and its output shaft is connected to the roller cutting fixed seat 7 to drive the roller cutting fixed seat 7 to reciprocate. The second driving member 9 is a servo motor, and the first spur gear 10 is installed on its output shaft. Both ends of the roller cutter 6 are assembled to the roller cutting fixed seat 7 through bearings.

[0050] The first driving member 8 is a cylinder or an electric cylinder, and its output shaft is connected to the roller cutting fixed seat 7 to drive the roller cutting fixed seat 7 to reciprocate. The second driving member 9 is a servo motor, and the first spur gear 10 is installed on its output shaft. Both ends of the roller cutter 6 are assembled to the roller cutting fixed seat 7 through bearings. By using a servo motor for the second driving member 9, the rotation speed of the roller cutter 6 can be precisely controlled.

[0051] Referring to Figure 2 and Figure 3 , it further includes a feeding assembly 15. The feeding assembly 15 is installed on the frame 1, and it includes a driving roller 16, a feeding pressure roller 17 and a third driving member 18. Both the driving roller 16 and the feeding pressure roller 17 are pivotally connected to the mounting bracket 13, and are located in front of the roller cutter 6 in the feeding direction, and cooperate with each other to press the strip. The third driving member 18 is configured to drive the driving roller 16 to rotate so as to feed the strip through the cooperation between the driving roller 16 and the feeding pressure roller 17. The third driving member 18 is a servo motor, and its output shaft is connected to the driving roller 16 through a belt.

[0052] Through the feeding assembly 15, the strip can be driven to the position of the roller cutter 6 and cooperate with the roller cutter 6 to achieve continuous and high-speed cutting of the strip. By using a servo motor for the third driving member 18, the rotation speed of the driving roller 16 can be precisely controlled, which is convenient for cooperation with the roller cutter 6.

[0053] In addition, a discharge chute 19 is provided. The discharge chute 19 is installed on the installation table and is located behind the roller cutter 6 in the feeding direction. Through the discharge chute 19, the cut strip can be gathered, which is convenient for packing and standby.
