Description

Technical Field

[0001] This utility model belongs to the field of fabric cutting technology, and relates to an ultrasonic cutting device for sunshade composite fabric. Background Technology

[0002] Existing sunshade fabrics are all made of composite materials to improve their effect. During processing, they need to be cut with special cutting equipment using a die. However, cutting composite materials with a die can easily cause the cut edges of the composite materials to fray and fraying. After the edges fray, prolonged contact and friction will expand the frayed area and affect the use.

[0003] Application No. 202323315460.7 discloses an ultrasonic cutting device, including an ultrasonic head and an ultrasonic mold. The ultrasonic head is used to connect and fix with the ultrasonic welding probe of an ultrasonic welding machine. The surface of the ultrasonic head facing away from the ultrasonic welding probe is flat. The ultrasonic mold is used to be placed on the ultrasonic welding machine. The ultrasonic mold corresponds to the ultrasonic head and is located below the ultrasonic head. The surface of the ultrasonic mold facing the ultrasonic head has a raised blade. The ultrasonic cutting device of this utility model is used in conjunction with an ultrasonic welding machine to realize ultrasonic high-frequency vibration cutting of nylon braided materials and achieve the effect of cutting and welding of nylon braided materials. This effectively solves the problem that existing die-cutting of nylon braided materials easily leads to fuzzing and frayed edges at the cut edges.

[0004] The ultrasonic mold structures of the above-mentioned devices are all fixed and have only a single-structure protruding blade, which can only cut composite fabrics of a single nature and cannot meet the existing requirements for cutting composite fabrics, so improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic cutting device for sunshade composite fabrics to solve the problems mentioned in the background art.

[0006] An ultrasonic cutting device for sunshade composite fabric includes a support base, an upper support frame, and a lower support frame. The lower support frame is installed at the top of the support base. Rotating inner discs are movably installed on both sides of the lower support frame via pins, and an ultrasonic mold is installed between the two rotating inner discs. The top and bottom of the ultrasonic mold are equipped with protruding blades. Two limiting rods are provided on both sides of the lower support frame. Limiting holes are opened on the side of the rotating inner discs, and one end of the limiting rod is inserted into the limiting hole. A pressure plate is installed on the top side of the lower support frame via a guide rod, and a clamping screw is provided on the side of the pressure plate.

[0007] In the aforementioned ultrasonic cutting device for sunshade fabric composite material, an upper support frame is provided at the top of the support base, an ultrasonic welding machine is installed at the top of the upper support frame, and an ultrasonic welding probe connected to the ultrasonic welding machine is provided inside the upper support frame.

[0008] In the aforementioned ultrasonic cutting device for sunshade fabric composite materials, a connecting rod is provided at the top of the ultrasonic welding probe, and an ultrasonic head is connected to the bottom of the ultrasonic welding probe through the connecting rod, with the ultrasonic head positioned at the top of the ultrasonic mold.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] An ultrasonic cutting device for sunshade fabric composite materials includes a support base frame 1, an upper support frame 2, and a lower support frame 3. The lower support frame 3 is installed at the top of the support base frame 1. Rotating inner discs 6 are movably installed on both sides of the lower support frame 3 via pins, and an ultrasonic mold 7 is installed between the two rotating inner discs 6. Protruding blades 8 are installed at the top and bottom of the ultrasonic mold 7. Two limiting rods 9 are provided on both sides of the lower support frame 3. Limiting holes 16 are opened on the side of the rotating inner discs 6, and one end of the limiting rod 9 is inserted into the limiting hole 16. A pressure plate 18 is installed on the top side of the lower support frame 3 via a guide rod. A clamping screw 10 is provided on the side of the pressure plate 18. The pressure plate 18 of this application mainly clamps and limits the two ends of the fabric, and a positioning screw is provided at the end of the pressure plate 18. A positioning hole is provided on the side of the lower support frame 3, and the positioning screw can be inserted into the positioning hole to limit the pressure plate 18.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the ultrasonic cutting device for sunshade fabric composite material of this utility model has an upper support frame 2 at the top of the support base 1, an ultrasonic welding machine 12 at the top of the upper support frame 2, and an ultrasonic welding probe 13 connected to the ultrasonic welding machine 12 inside the upper support frame 2. The ultrasonic welding machine 12 and the ultrasonic welding probe 13 of this application are commercially available and known to those skilled in the art. We are only using them here and have not made any structural or functional improvements. We will not go into detail here. It should be noted that the ultrasonic welding probe 13 of the ultrasonic welding machine 12 can be raised and lowered and can generate high-frequency ultrasonic vibrations, which are existing known technologies and will not be described here.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ultrasonic cutting device for sunshade fabric composite material of this utility model has a connecting rod 14 at the top of the ultrasonic welding probe 13, and the bottom of the ultrasonic welding probe 13 is connected to the ultrasonic head 15 through the connecting rod 14, and the ultrasonic head 15 is located at the top of the ultrasonic mold 7.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ultrasonic cutting device for sunshade fabric composite material of this utility model has a rotating rod connected to the center of the rotating inner plate 6. One end of the rotating rod passes through the lower support frame 3 and is connected to the knob 4 on the outside of the lower support frame 3. Rotating the knob 4 can adjust the rotating rod to rotate, thereby driving the rotating inner plate 6 to rotate.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the ultrasonic cutting device for sunshade composite fabric of this utility model has, specifically, an inner push block 17 slidably arranged on both sides of the inner support frame 3, and a supporting inner plate 19 movably arranged on the side of the inner push block 17. The outer side of the supporting inner plate 19 is provided with a pushing inclined surface that cooperates with the inner side of the inner push block 17. One end of the limiting rod 9 is connected to the side of the supporting inner plate 19, and a return spring 20 is provided in the middle of the supporting inner plate 19. The return spring 20 is a well-known device in the art that can be directly purchased from the market. Here we are just using it without making any structural or functional improvements. We will not go into details here. The return spring 20 supports the supporting inner plate 19. When the supporting inner plate 19 loses the support of the inner push block 17, the supporting inner plate 19 can move outward under the push of the return spring 20, thereby mobilizing the two limiting rods 9 to retract, so that the limiting rods 9 retract from the inside of the limiting hole 16, so that the rotating inner plate 6 loses its limit, thereby facilitating the rotation of the rotating inner plate 6.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ultrasonic cutting device for sunshade composite fabric of this utility model has two push rods 11 on the outer side of the lower support frame 3, and a pull rod 5 is provided between the two push rods 11. One end of the push rod 11 passes through the lower support frame 3 and is connected to the inner push block 17 inside the lower support frame 3. Pulling the pull rod 5 will move the push rod 11, so that the push rod 11 pushes the inner push block 17.

[0026] This utility model relates to an ultrasonic cutting device for sunshade fabric composite materials. During processing, by rotating the knob 4, the inner rotating disk 6 is rotated to adjust the position of the protruding blade 8 on the top of the ultrasonic mold 7 so that the required protruding blade 8 is facing upwards. Then, the push rod 11 is pushed inwards, which pushes the inner push block 17 inside the lower support frame 3 to slide. When the inner push block 17 slides, it can contact the inner support plate 19 and push the inner support plate 19 outwards. The two limiting rods 9 fixed on the inner support plate 19 extend outwards, and one end of the limiting rod 9 is inserted into the limiting hole 16 on the side of the rotating inner disk 6, thereby positioning the ultrasonic mold 7. Then, the composite fabric is placed on the top position of the protruding blade 8, and the ultrasonic head 15 is connected and fixed to the ultrasonic welding probe 13 of the ultrasonic welding machine 12. Because the ultrasonic welding probe 13 of the ultrasonic welding machine 12 can move up and down and can generate high-frequency ultrasonic vibrations, the ultrasonic head 15 can also move upwards. The ultrasonic generator can raise and lower the ultrasonic head 15 and generate high-frequency ultrasonic vibrations, aligning the ultrasonic module 7 with the ultrasonic head 15. Simultaneously, the ultrasonic module 7 is positioned below the ultrasonic head 15. When cutting composite fabric materials, the material to be cut is placed between the raised blade 8 and the plane of the ultrasonic head 15 facing away from the ultrasonic welding probe 13. By starting the ultrasonic welding machine 12, the ultrasonic head 15 is driven to descend and adhere to the upper surface of the composite fabric material. The composite fabric to be cut completes ultrasonic high-frequency vibration cutting under the action of the raised blade 8 and the ultrasonic head 15. The contour trajectory of the raised blade 8 is the cut mark of the composite fabric. Because ultrasonic high-frequency vibration cutting is performed through the principle of heating and melting, it seals the cut edge of the composite fabric, effectively preventing fuzzing and fraying at the cut edge, improving the processing efficiency of the composite fabric, and solving the problem of fuzzing and fraying at the cut edge of the composite fabric.
