Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing equipment technology, and in particular to an ultrasonic cutter wheel. Background Technology

[0002] In the garment manufacturing industry, ultrasonic cutting wheels are commonly used to cut fabrics. Especially in the underwear industry, when cutting fabrics or bra cup edges, the ultrasonic cutting process can result in unstable weld strength, and after washing, the processed areas are prone to opening defects.

[0003] Currently, manufacturers and research institutions have not taken effective measures to address this issue. For example, Chinese utility model patent CN201080009Y discloses a welding head for an ultrasonic seamless sewing machine core. This welding head has a disc-shaped body, which is symmetrical in both radial and axial sections along its center. An installation part is located at the center of the body, and the thickness of the body gradually decreases from the axial center to the edge. The outermost part of the body may also have a thickened outer edge. When this utility model is applied to ultrasonic welding of thermoplastic fabrics, the fabric is pressed between the pressure roller and the outer surface of the ultrasonic welding head. The rotation of the welding head drives the fabric forward. Under the action of ultrasound, the fabric heats up and melts, bonding two or more layers of fabric together, thereby achieving the purpose of welding the fabric. However, the patented technology does not disclose the installation structure of the pressure roller. Usually, the pressure roller is installed on both sides of the welding head. Before welding the fabric, the welding head presses down the pressure roller to fix the fabric. When welding, the pressure roller is lifted up, which cannot apply force to the fabric and increase the welding strength. Therefore, the welding strength is unstable, and the processing position is prone to open defects after washing. Utility Model Content

[0004] In view of this, the present invention aims to provide an ultrasonic cutting wheel, which employs a pressing element provided on at least one side of the cutting wheel body. The outer diameter of the annular pressing element is higher than the cutting diameter. The pressing element is set in the mounting groove of the cutting wheel and is interference-fitted with the bottom surface of the mounting groove. When welding fabric, the pressing element rotates synchronously with the cutting wheel and always presses on the fabric. The pressing element is elastic, and the outer side wall of the mounting groove away from the cutting is inclined. This solves the problems of unstable welding strength and defects such as the easy appearance of openings at the processing position after washing.

[0005] To solve the above problems, this utility model provides an ultrasonic cutter wheel, comprising:

[0006] The main body is disc-shaped, and there are cuts on the outer periphery of the main body;

[0007] A pressure member is fixed on the circumferential surface of the body, and the outer surface of the pressure member protrudes beyond the outer surface of the cut.

[0008] Furthermore, a mounting groove is provided on the circumference of at least one side of the cut, and the pressing element is embedded in the mounting groove.

[0009] Furthermore, the pressing component is annular and is fitted inside the mounting groove.

[0010] Furthermore, the inner ring diameter of the pressing component is smaller than the bottom diameter of the mounting groove.

[0011] Furthermore, the pressure element is an elastic element.

[0012] Furthermore, the diameter of the sidewall of the mounting groove on the side away from the cut is smaller than the diameter of the pressure member.

[0013] Furthermore, the outer wall of the mounting groove on the side away from the cut has an incline, and the wall thickness of the side wall gradually increases from the circumferential end to the center.

[0014] Furthermore, one pressure member is provided on each side of the cut, and the two pressure members are symmetrically arranged with respect to the cut.

[0015] Furthermore, the cut can be straight or non-straight.

[0016] Furthermore, the non-linear cut includes non-linear cuts with regular shapes and non-linear cuts with irregular shapes.

[0017] Compared with the prior art, the ultrasonic cutter wheel of this utility model has the following advantages:

[0018] The advantage of this technical solution lies in the use of a pressure member on at least one side of the cutter wheel body. The outer diameter of the annular pressure member is higher than the cutting diameter. The pressure member is set in the mounting groove of the cutter wheel and is interference-fitted with the bottom surface of the mounting groove. When welding the fabric, the pressure member rotates synchronously with the cutter wheel and always presses on the fabric. The pressure member is elastic, and the outer side wall of the mounting groove away from the cutting is inclined, which prolongs the pressing and cooling time of the hot melt material, increases the stability of the weld strength, avoids the defect of opening at the processing position after washing, and improves the processing quality.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In this utility model, the descriptions involving "first," "second," "upper," and "lower," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "upper," or "lower" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. Where the technical solutions of the embodiments can be combined, they are all within the protection scope claimed by this utility model.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 and Figure 4 As shown, an ultrasonic cutter wheel includes: a body 1 and a pressing component 2. The body 1 is disc-shaped, and a notch 11 is provided on the outer periphery of the body 1; the pressing component 2 is fixed on the circumferential surface of the body 1, and the outer surface of the pressing component 2 protrudes from the outer surface of the notch 11.

[0029] like Figure 2 As shown, the power shaft mounting hole 13 of the ultrasonic cutter wheel is connected to the electrode shaft of the ultrasonic machine, and the mounting screw hole 14 is connected to the corresponding hole of the ultrasonic machine by bolts. The width w of the cutter wheel slit 11 is 0.1~0.8mm. The slit 11 has an angle on both sides, making it approximately trapezoidal. The angle between the two inclined sides is preferably 60~135°. Specific width and angle data need to be adjusted according to the composition, thickness, or combination of the fabric being cut.

[0030] By fixing the pressure piece 2 to the circumferential surface of the cutter wheel body 1, and with its outer surface protruding from the cut 11, the pressure piece 2 is always pressed against the surface of the fabric when the cutter wheel is welding it, thus applying force to the fabric. As the cutter wheel welds the fabric, the force of the pressure piece 2 reinforces the weld position, effectively extending the heat fusion time and the cooling time of the hot melt material, increasing the weld strength, preventing the weld position from opening after washing, and improving the processing quality.

[0031] Furthermore, an installation groove 12 is provided on the circumference of at least one side of the cut 11, and the pressing element 2 is embedded in the installation groove 12.

[0032] The mounting groove 12 is provided to facilitate the installation of the pressure component 2. The bottom edge of the mounting groove 12 has a diameter of d1 and a width of w1. It is rectangular in shape, with two straight edges at right angles to the bottom edge. The minimum perpendicular distance between the straight edge closest to the cutter edge of the cutter wheel and the centripetal normal of the midpoint of the cutter edge of the cutter wheel is t, where 1mm ≤ t ≤ 5mm.

[0033] Furthermore, the pressing element 2 is annular and is fitted inside the mounting groove 12.

[0034] like Figures 1 to 3 As shown, the annular pressure element 2 improves the uniformity of pressure applied to the fabric. The maximum outer diameter is D2, the inner diameter is d2, and the thickness is w2. The dimensional relationship between the ultrasonic cutter wheel (1) and the matching pressure element 2 (2) at the mounting groove 12 (12) of the matching pressure element 2 is as follows:

[0035] d1 = d2 - u, u = (0.2 - 1.2) mm

[0036] D1 = D2 – v, v = (0.5 – 2.0) mm

[0037] w1=w2+x, x=(-0.2–0.6)mm.

[0038] Furthermore, the inner ring diameter of the pressing component 2 is smaller than the bottom diameter of the mounting groove 12.

[0039] The pressure component 2 is interference-fitted with the bottom of the mounting groove 12, ensuring a secure installation and enabling the pressure component 2 to rotate synchronously with the cutting wheel of the cutting edge 11.

[0040] Furthermore, the pressure member 2 is an elastic member.

[0041] The pressure piece 2 is elastic, which facilitates its installation. During use, it eliminates the height difference between the pressure piece 2 and the cut 11, making welding easier, while also increasing the pressure on the fabric, further improving the weld strength.

[0042] Furthermore, the diameter of the side wall of the mounting groove 12 on the side away from the cut 11 is smaller than the diameter of the pressure member 2.

[0043] The side wall diameter is smaller than the diameter of the pressure component 2, which reduces the deformation of the pressure component 2 during installation and facilitates installation.

[0044] Furthermore, the outer wall of the mounting groove 12 on the side away from the cutout 11 has an incline, and the wall thickness of the side wall gradually increases from the circumferential end to the center.

[0045] To further facilitate the installation of the pressure component 2, the side wall is sloped.

[0046] Furthermore, one pressure member 2 is provided on each side of the cut 11, and the two pressure members 2 are symmetrically arranged with respect to the cut 11.

[0047] A pressure piece 2 is set on each side of the cut 11, which can apply pressure to the fabric on both sides of the welding position, further increasing the welding strength.

[0048] Furthermore, the cut 11 can be straight or non-straight.

[0049] According to the design requirements and welding process requirements, the cut 11 can be made into a straight line or a non-straight line. When the cut 11 is non-straight line, a certain pattern can be formed at the welding position, which improves the aesthetics of the welding position.

[0050] Furthermore, the non-linear cut 11 includes non-linear cuts with regular shapes and non-linear cuts with irregular shapes.

[0051] The non-linear cut 11 can be of any shape, and can be freely selected according to design requirements.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
