Description

Technical Field

[0001] This utility model relates to the field of garment cutting equipment technology, and in particular to an ultrasonic cutting wheel for automatic material feeding. Background Technology

[0002] In the garment manufacturing industry, ultrasonic cutting equipment is commonly used for garment cutting. When cutting materials or bra cups, the material is cut and hollowed out by the ultrasonic cutting equipment, which encloses the desired shape or pattern, resulting in hollowed-out material or bra cups with the desired pattern or shape. Various research institutions and garment manufacturers have developed different types of ultrasonic cutting equipment. All ultrasonic cutting equipment is equipped with a cutting wheel, which performs the cutting process.

[0003] The cutting wheel plays a crucial role in the quality of cutting. For example, Chinese utility model patent CN108755092A discloses a small garment cutting head for partial cutting of clothing fabric. It includes a screw, one end of which is connected to an upper support. A lower support is movably connected to the bottom of the upper support, and an elastic rod connects the upper and lower supports. The cutting wheel can rotate between the cutting wheel holder and the lower support, and is used by the cutting machine to trim arc-shaped fabric. Due to resistance, the cutting wheel, through the rotation between the bearing inside the lower support and the cutting wheel holder, always keeps the edge of the cutting disc in contact with the fabric, easily cutting arcs. The outer diameter of the cutting disc is slightly larger than that of the outer wheels on both sides. However, during the cutting process, excess material may stick to the ultrasonic cutter, affecting its cutting function and requiring timely cleaning, thus reducing production efficiency. Utility Model Content

[0004] In view of this, the present invention aims to provide an ultrasonic cutter wheel with automatic material discharge. It adopts a chip removal channel that connects the cutting edge and the outside of the cutter body inside the cutter head and the cutter body. The excess material cut off is discharged in time through the chip removal channel, which solves the problem that the excess material cut off sticks to the ultrasonic cutter, affecting the cutting function of the ultrasonic cutter, requiring timely cleaning, and reducing production efficiency.

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

[0006] The blade is disc-shaped.

[0007] The cutting head is disposed on the outer circumferential surface of the cutting body, and the outer end of the cutting head is the cutting edge surface;

[0008] The chip removal channel has one end connected to the cutting edge and the other end connected to the outside of the blade body.

[0009] Furthermore, the chip removal channel includes a chip inlet and a chip outlet. The chip inlet extends from the cutting edge towards the blade body, and the chip outlet is disposed on the blade body. The chip inlet and the chip outlet are connected.

[0010] Furthermore, the chip inlet is a straight hole extending from the cutting edge to the interior of the blade body, and the chip outlet is a straight hole extending at least one end to the side of the blade body.

[0011] Furthermore, the chip-exit section is connected to the two sides opposite to the blade body.

[0012] Furthermore, the connection between the chip inlet and the chip outlet is rounded or chamfered.

[0013] Furthermore, the axis of the chip infeed section is perpendicular to the axis of the blade body, and the axis of the chip outlet section is parallel to the axis of the blade body.

[0014] Furthermore, the cutter head is frustum-shaped, and the outer diameter of the cutter head gradually decreases along the extension direction from the connection between the cutter head and the cutter body to the end face of the cutter head;

[0015] The cutting edge can be curved, conical, flat, or irregular.

[0016] Furthermore, the inner diameter of the chip inlet is d, where d ≥ 2.5 mm;

[0017] The distance between the edge of the chip inlet and the outer edge of the cutting edge is the cutting edge, and the cutting edge width is t, 0.05mm≤t≤0.4mm.

[0018] Furthermore, the height of the cutter head is E, where 2mm ≤ E ≤ 8mm;

[0019] The depth of the chip inlet is H, and the thickness between the hole wall of the chip outlet and the outer periphery of the cutter body is M, where H = E + M, and 2 mm ≤ M ≤ 10 mm.

[0020] Furthermore, the inner diameter of the chip discharge section is D, where D = d + f, f is a compensation value, and 2mm ≤ f ≤ 8mm.

[0021] Compared with the prior art, the ultrasonic cutter wheel for automatic material feeding described in this utility model has the following advantages:

[0022] The advantage of this technical solution lies in the use of a chip removal channel inside the cutter head and body that connects the cutting edge to the outside of the cutter body. This allows excess material to be discharged through the chip removal channel in a timely manner, preventing excess material from sticking to the ultrasonic cutter. This improves the cutting function of the ultrasonic cutter, eliminates the need for timely cleaning, and increases production efficiency. Attached Figure Description

[0029] 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.

[0030] 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.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 3 As shown, an ultrasonic cutter wheel with automatic material discharge includes: a cutter body 100, a cutter head 200, and a chip removal channel 300. The cutter body 100 is disc-shaped. The cutter head 200 is disposed on the outer circumferential surface of the cutter body 100, and the outer end of the cutter head 200 is a cutting edge. The chip removal channel 300 has one end connected to the cutting edge and the other end connected to the outside of the cutter body 100.

[0033] The blade body 100, serving as the base of the cutting wheel, is disc-shaped. A mounting hole 110 is located at the center of the blade body 100, and multiple fixing holes 120 are evenly distributed around the mounting hole 110. The cutting wheel is mounted on the ultrasonic cutting device through the mounting hole 110, and the fixing holes 120 further secure the cutting wheel and restrict its rotation relative to the mounting shaft, achieving synchronous rotation between the cutting wheel and the ultrasonic device's mounting shaft. In a first embodiment, the cutter head 200 is mounted on the outer circumferential surface of the blade body 100, and can be annularly sleeved on the outer circumference, forming a 360° integral cutter head 200. In a second embodiment, a small cutter head 200 can also be used, fixed on the outer circumference of the blade body 100. There can be one or more small cutter heads 200, evenly distributed on the outer circumferential surface of the blade body 100. Regardless of the embodiment, the outer circumferential surface of the cutter head 200 is a cutting edge for cutting fabric. In this embodiment, the second embodiment is preferred. By setting a chip removal channel 300 on the cutter wheel, with one end of the chip removal channel 300 connected to the cutting edge and the other end connected to the outside of the cutter body 100, the cut material is promptly discharged through the chip removal channel 300 during the cutting process, preventing excess material from sticking to the ultrasonic cutter, improving the cutting function of the ultrasonic cutter, eliminating the need for timely cleaning, and increasing production efficiency.

[0034] Furthermore, the chip removal channel 300 includes a chip inlet 310 and a chip outlet 320. The chip inlet 310 extends from the cutting edge towards the blade body 100, and the chip outlet 320 is disposed on the blade body 100. The chip inlet 310 and the chip outlet 320 are connected.

[0035] During cutting, the blade cuts the fabric, and the cut material enters the chip discharge channel 300 through the chip inlet 310. As the amount of cut material increases, it moves along the chip discharge channel 300 toward the blade body 100 and is discharged to the outside of the pulley through the chip outlet 320.

[0036] The chip removal channel 300 can be located on the side of the cutter wheel, forming a groove. It can be located on one side or both sides of the cutter wheel. Alternatively, the chip removal channel 300 can be located inside the cutter wheel, forming a hole.

[0037] Preferably, the chip inlet 310 is a straight hole extending from the cutting edge towards the interior of the blade body 100, and the chip outlet 320 is a straight hole extending at least one end to the side of the blade body 100.

[0038] In this embodiment, the second implementation method is preferred, that is, the chip removal channel 300 is disposed inside the cutter wheel. Specifically, the straight hole of the chip inlet 310 extends from the cutting edge towards the interior of the cutter body 100, and the cutter body 100 is provided with a straight hole of the chip outlet 320. The straight holes of the two parts can be at any angle. Preferably, the axis of the chip inlet 310 is perpendicular to the axis of the mounting hole 110, and the axis of the chip outlet 320 is parallel to the axis of the mounting hole 110. The chip outlet 320 can be a blind hole communicating with one side of the cutter body 100, or it can be a through hole extending to both sides of the cutter body 100 and communicating with the outside.

[0039] Preferably, the chip removal section 320 is connected to the two opposite sides of the blade body 100.

[0040] The preferred design of the chip removal section 320, with through holes extending to both sides, is more conducive to the discharge of the cut material.

[0041] Furthermore, the connection between the chip inlet 310 and the chip outlet 320 is rounded or chamfered.

[0042] Chamfering or rounding the connection between the chip inlet 310 and the chip outlet 320 facilitates the discharge of materials and prevents the connection from cutting off the materials and blocking the chip discharge channel 300.

[0043] Furthermore, the axis of the chip inlet 310 is perpendicular to the axis of the blade body 100, and the axis of the chip outlet 320 is parallel to the axis of the blade body 100.

[0044] The arrangement of the chip inlet 310 and chip outlet 320 in this embodiment facilitates the discharge of materials.

[0045] Furthermore, the cutting head 200 is frustum-shaped, and its outer diameter gradually decreases along the extension direction from the connection point between the cutting head 200 and the cutting body 100 towards the end face of the cutting head 200. The cutting edge surface is an arc surface, a conical surface, a plane, or an irregular surface.

[0046] The blade head 200 can be of any shape, but a frustum shape is preferred. The cutting edge has a chip inlet hole, and the cutting edge needs a certain sharpness, which necessitates thinning the wall thickness of the chip inlet hole at the end of the cutting edge. If a cylindrical blade head 200 is used, the sharpness increases, but the strength of the blade head 200 decreases, making it difficult to apply force during cutting. Using a frustum-shaped blade head 200 enhances its strength.

[0047] The cutting edge can be designed in various shapes, depending on the cutting effect, cutting process requirements, and processing pattern requirements. For example, if a specially designed hollow pattern needs to be cut out, the shape of the cutting edge can be designed accordingly. However, the cutting edge must be a completely closed shape, without any openings or breaks. The cutting edges of each 200mm cutting head must be located on a circumferential surface with the same diameter as the central axis of the cutting wheel.

[0048] The cutter head 200 and the cutter body 100 can be integrally formed, but this is not easy to manufacture. Preferably, the cutter head 200 is fixed to the cutter body 100 by welding or other methods.

[0049] Furthermore, such as Figure 4 As shown, the inner diameter of the chip inlet 310 is d, where d ≥ 2.5 mm. The distance between the edge of the chip inlet 310 and the outer edge of the cutting edge is the cutting edge, and the width of the cutting edge is t, where 0.05 mm ≤ t ≤ 0.4 mm.

[0050] With the above parameter settings, an aperture of 2.5mm or more ensures smooth material discharge, and the blade width ensures the sharpness of the blade.

[0051] Furthermore, the height of the cutter head 200 is E, where 2mm ≤ E ≤ 8mm. The depth of the chip inlet 310 is H, and the thickness between the hole wall of the chip outlet 320 and the outer periphery of the cutter body 100 is M, where H = E + M, and 2mm ≤ M ≤ 10mm.

[0052] Using the parameter settings within the above range, the height of the cutter head 200 can ensure its strength and cutting effect. The thickness M can ensure the strength of the chip-exit section 320.

[0053] Furthermore, the inner diameter of the chip discharge section 320 is D, where D = d + f, f is a compensation value, and 2mm ≤ f ≤ 8mm.

[0054] By establishing the dimensional relationship between the chip inlet aperture 310 and the chip outlet aperture 320 through compensation values, the chip removal effect can be optimized.

[0055] As per the above relationship, the thickness of the preferred cutter body 100 is 4-50 mm.

[0056] 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.
