Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a repair tool for an ultrasonic welding sealing machine. Background Technology

[0002] This machine uses an ultrasonic energy concentrator to seal the packaging container at the sealing point. Ultrasonic energy is transmitted to the welding area via an upper welding component. Due to the high acoustic impedance at the welding area (the interface between two welded parts), localized high temperatures are generated. Because plastic has poor thermal conductivity, the heat cannot dissipate quickly and accumulates in the welding area, causing the contact surfaces of the two plastic parts to melt rapidly. With the application of pressure, they fuse together. After the ultrasonic waves stop, the pressure is maintained for a few seconds to allow solidification, forming a strong molecular chain and achieving the welding purpose. The weld strength is close to that of the original material, making it suitable for plastic container packaging.

[0003] Ultrasonic sealing machines are widely used in the automotive, electronics, medical, home appliance, non-woven clothing, office supplies, packaging, and toy industries. When using ultrasonic welding equipment, if the ultrasonic energy is not fully released and remains inside the ultrasonic welding head, the welding head will overheat, resulting in weak welds or even cracks. Improper operation, such as incorrect equipment settings leading to high pressure and high temperature on the welding head, or external impacts, can also damage the mesh pattern of the welding head mold.

[0004] Traditional aluminum alloy sheet texture processing often employs electrical discharge machining (EDM) or wire cutting. Because these methods are highly specialized and costly, they are typically discarded after a single use, increasing production costs. Utility Model Content

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a repair tool for an ultrasonic welding sealing machine, which includes: a connector and a spacer 4;

[0023] The connecting body includes a cone 1 and a cylinder 2. The large end of the cone 1 is coaxially connected to one end of the cylinder 2, and the other end of the cylinder 2 is sequentially connected to the center of multiple circular saw blades 3.

[0024] The spacer 4 is placed between two adjacent circular saw blades 3;

[0025] The small end of cone 1 corresponds to the Morse taper hole inserted into the machine tool.

[0026] The working process of the repair tool in the ultrasonic welding sealing machine is as follows:

[0027] The small end of the cone 1 is fitted into the spindle taper hole of the machine tool and the welding head mold is fixed. The machine tool spindle is started, which drives multiple circular saw blades 3 to rotate synchronously. The edge of the rotating circular saw blade 3 slides across the surface of the welding head mold along the first direction. The position of the welding head mold is adjusted and fixed again. The rotating circular saw blade 3 slides across the surface of the welding head mold along the second direction to repair the texture depth in the two directions of the cross mesh.

[0028] Specifically, the thickness of the spacer 4 matches the spacing between adjacent grooves of the cross-grain pattern, so that the spacing between adjacent circular saw blades 3 matches the spacing between adjacent parallel grooves of the cross-grain pattern. The spacer 4 is made of 40Cr steel with a hardness of HRC32-36.

[0029] Specifically, the circular saw blade 3 is made of superhard alloy steel. The superhard alloy saw blade (HRC≥68) allows for more than 2,000 mesh repair operations to be completed in a single resharpening. The diameter of the circular saw blade 3 is larger than the diameter of the cylinder 2.

[0030] Specifically, multiple circular saw blades 3 can complete the engraving of multiple parallel mesh patterns at one time, and in conjunction with the reciprocating feed of the machine tool, they can form a cross-mesh pattern texture repair.

[0031] Specifically, by adjusting the thickness of the spacer pad 4 with high precision (tolerance ±0.01mm), the spacing between adjacent circular saw blades 3 is controlled to ensure that the spacing of the mold mesh texture is consistent to ±0.05mm.

[0032] Specifically, the cone 1 adopts a standardized Morse taper shank to achieve rapid positioning with the machine tool spindle taper hole, which improves efficiency by more than 60% compared with traditional flange connection.

[0033] In a specific embodiment, it also includes a first fastening screw 5, which passes through the central holes of a plurality of circular saw blades 3 in sequence and is threaded to the other end of the cylinder 2.

[0034] In this embodiment, specifically, the first fastening screw 5 is threaded to the other end of the cylinder 2, which facilitates the disassembly and replacement of the circular saw blade 3.

[0035] Specifically, the first fastening screw 5 passes through the circular saw blade 3 and the spacer 4 in sequence, and is threaded to the other end of the cylinder 2 to form a rigid assembly with adjustable preload.

[0036] Specifically, a first pressure pad 6 is provided between the stop block at the end of the first fastening screw 5 and the circular saw blade 3, and a second pressure pad 7 is provided between the circular saw blade 3 and the cylinder 2 to improve the tightness of the arrangement of multiple circular saw blades 3. The first pressure pad 6 and the second pressure pad 7 are made of 40Cr steel with a hardness of HRC32-36.

[0037] In a specific embodiment, the cylinder 2 includes an inner cylinder 201, an outer sleeve 202, and a limiting plate 203. One end of the inner cylinder 201 is fixedly connected to the large end of the cone 1. The outer sleeve 202 is sleeved on the inner cylinder 201. The end of the outer sleeve 202 away from the cone 1 is the first port, which is fixedly connected to the periphery of the limiting plate 203. The other end of the inner cylinder 201 is provided with a screw hole 204. The limiting plate 203 is provided with a through hole 205. The first fastening screw 5 passes through the center hole and the through hole 205 of multiple circular saw blades 3 in sequence and is threaded to the screw hole 204.

[0038] In this embodiment, there are multiple outer sleeves 202, and the thickness of the limiting plate 203 at the first port of each outer sleeve 202 is different. This is because the lengths of the welding head molds to be repaired are not the same. When the length of the mold to be repaired is large, an outer sleeve 202 with a larger limiting plate thickness is used, and when the length of the mold to be repaired is small, an outer sleeve 202 with a smaller limiting plate thickness is used, so that the far end position that the circular saw blade 3 can reach can be adapted to the lengths of different welding head molds.

[0039] In a specific embodiment, the cylinder 2 also includes a limiting frustum 206. One end of the inner cylinder 201, the limiting frustum 206 and the large end of the cone 1 are fixedly connected in sequence. The end of the outer tube 202 near the cone 1 is the second port, which is connected to the limiting frustum 206.

[0040] In this embodiment, specifically, the limiting frustum 206 and the second port are in contact with each other, which further restricts the axial movement of the outer tube 202 relative to the inner cylinder 201 and further improves the axial stability of the outer tube 202.

[0041] In a specific embodiment, it also includes an annular baffle 8 and a second fastening screw 9. The second fastening screw 9 passes through the annular baffle 8 and the Morse taper hole of the machine tool in sequence, and is threaded to the small end of the cone 1.

[0042] In this embodiment, specifically, the second fastening screw 9 passes through the center hole of the annular baffle 8 and the small-diameter end of the Morse taper hole of the machine tool in sequence, so that the annular baffle 8 is pressed against the outer edge of the small-diameter end of the Morse taper hole of the machine tool, thereby tightening the cone 1 with the second fastening screw 9, preventing the cone 1 from detaching from the large-diameter end of the Morse taper hole, thereby preventing the tool workpiece from falling and being damaged.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
