Description

Technical Field

[0001] The present invention relates to the technical field of spectacle cleaning cloth production, and particularly to an ultrasonic bonding device and a production process of a high-performance spectacle cleaning cloth. Background Art

[0002] A spectacle cleaning cloth is a cloth used for cleaning and wiping spectacle lenses. Since the surface of spectacle lenses usually contains a film layer with specific functions, in order to minimize damage to the film layer by the spectacle cleaning cloth, the spectacle cleaning cloth needs to be softer and have a more compact fiber arrangement to prevent dust particles from being embedded in the fiber gaps of the spectacle cleaning cloth.

[0003] The spectacle cleaning cloth can be made of non-woven fabric or textile fabric. The fiber arrangement of the textile fabric is not compact enough and the texture is not soft enough. Although the non-woven fabric has a soft texture, it has many gaps on the surface, which leads to the embedding of dust particles, causing wear to the film layer of the spectacle lenses during the wiping process, and it is also prone to shedding hair during use, resulting in secondary pollution problems for the spectacle lenses and thus needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultrasonic bonding device and a production process of a high-performance spectacle cleaning cloth, so as to improve the wiping effect of the spectacle cleaning cloth and avoid the problem of hair shedding.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] Such as Figure 1 The ultrasonic bonding device shown includes: an ultrasonic generator, a roller, a transducer, and a welding head. The transducer is suspended above the roller, the welding head is arranged at the bottom of the transducer and points downward to the roller, and the ultrasonic generator is connected to the transducer. The ultrasonic generator converts the current into a high-frequency electrical signal, and the transducer receives the high-frequency electrical signal to perform mechanical vibration, driving the high-frequency vibration of the welding head.

[0007] Among them, the roller is densely provided with air holes.

[0008] Among them, it further includes an air knife. The air knife is suspended in front of the transducer, and the air outlet of the air knife obliquely points downward to the lower part of the welding head.

[0009] Among them, the number of the rollers is at least 1.

[0010] To achieve this purpose, the present invention adopts the following technical solutions:

[0011] A production process of a high-performance spectacle cleaning cloth includes the following steps:

[0012] a. Processing of superfine denier fibers: The polymer is heated by a spunbond - meltblown device. After the polymer reaches its melting point and becomes in a molten state, it is ejected through an orifice plate and then cooled and solidified to form superfine denier fibers.

[0013] b. Web laying: The superfine denier fibers are introduced into a carding machine for carding and then web - laid to obtain a fiber web composed of superfine denier fibers.

[0014] c. Glue - free bonding: Multiple layers of fiber webs are stacked up and down and then fed into an ultrasonic bonding device. The multi - layer fiber webs are guided by a roller. When the multi - layer fiber webs pass through the top surface of the roller, the transducer above the roller drives the vibration of the welding head. Through the contact between the welding head and the multi - layer fiber webs, the vibration energy is transmitted to the multi - layer fiber webs, causing the superfine denier fibers in the multi - layer fiber webs to generate intense friction under the welding head. The temperature rises rapidly, causing the local melting of the superfine denier fibers to obtain molten material. The molten material penetrates through the multi - layer fiber webs to achieve the composite of the multi - layer fiber webs, and a glasses wiping cloth is obtained.

[0015] Among them, the superfine denier fibers are polyester superfine denier fibers.

[0016] Among them, the fineness of the superfine denier fibers is less than 0.3 denier.

[0017] Among them, it also includes a cooling step. Through an air knife suspended in front of the transducer, air is blown to the welding head and the superfine denier fibers below it for cooling, and the penetration of the molten material is accelerated by the air flow.

[0018] Among them, the number of times of glue - free bonding is at least 1 time.

[0019] The beneficial effects of the present invention: An ultrasonic bonding device and a production process of a high - performance glasses wiping cloth adopt superfine denier fibers obtained by spunbond - meltblown, and use an ultrasonic bonding device to composite multi - layer fiber webs. The obtained glasses wiping cloth ensures the tightness of fiber arrangement, has a good wiping effect, does not require glue, and avoids the problem of shedding hairs during the wiping use process. Brief Description of the Drawings

[0020] Figure 1 It is a schematic structural diagram of the ultrasonic bonding device of the present invention. Detailed Description of the Embodiment

[0021] The following combines Figure 1 and further illustrates the technical solution of the present invention through specific embodiments.

[0022] As Figure 1 shown in the ultrasonic bonding device, it includes: an ultrasonic generator 4, a roller 1, a transducer 3, a welding head 2, and an air knife 5. The transducer 3 is suspended above the roller 1, and the multi - layer fiber web 6 is guided by the roller 1.

[0023] The welding head 2 is arranged at the bottom of the transducer 3 and points downward to the roller 1. The ultrasonic generator 4 is connected to the transducer 3. The ultrasonic generator 4 converts the current into high-frequency electrical signals. The transducer 3 receives the high-frequency electrical signals for mechanical vibration, driving the high-frequency vibration of the welding head 2. The vibration frequency is as high as more than 20,000 times per second, which can cause the fibers in the multi-layer fiber web 6 to rub violently to generate heat, making the temperature of the fiber friction surface reach the melting point, obtaining a partially molten material. The molten material penetrates the multi-layer fiber web 6 and solidifies after cooling.

[0024] The air knife 5 is suspended in front of the transducer 3. The air outlet of the air knife 5 obliquely points downward to the lower part of the welding head 2. The air knife 5 blows air to the welding head 2 and the ultra-fine denier fibers below it, which can not only cool but also accelerate the penetration of the molten material through the air flow, improving the composite effect.

[0025] As Figure 1 shown, the roller 1 is densely provided with air holes, which is beneficial to the cooling and exhaust of the multi-layer fiber web 6 and improves the penetration effect of the molten material. In this embodiment, the number of the rollers 1 is at least 1, and multiple rollers 1 can be used to cooperate with the transducer 3 and the welding head 2 for multiple non-glue bonding to ensure the composite effect and avoid the problem of hair loss.

[0026] A production process of a high-performance glasses wiping cloth includes the following steps:

[0027] a. Processing of ultra-fine denier fibers: Through a meltblown device, the polymer is heated. After the polymer reaches the melting point, it is in a molten state and then ejected through an orifice plate. After cooling and solidification, ultra-fine denier fibers are formed;

[0028] In this embodiment, the ultra-fine denier fibers are polyester ultra-fine denier fibers, which have high tensile strength and good wear resistance. The fineness of the ultra-fine denier fibers is less than 0.3 denier, which is relatively thin and has a soft texture, which is beneficial to improving the tightness of fiber arrangement, enhancing the wiping performance of the glasses wiping cloth, reducing the voids on the glasses wiping cloth, avoiding the problem of dust accumulation, and facilitating cleaning;

[0029] b. Web laying: The ultra-fine denier fibers are introduced into a carding machine for carding and then web laying to obtain a fiber web composed of ultra-fine denier fibers;

[0030] c. Glue - free bonding: Stack the three - layer fiber webs up and down and then feed them into an ultrasonic bonding device. Guide the multi - layer fiber web 6 through the roller 1. When the multi - layer fiber web 6 passes through the top surface of the roller 1, drive the vibration of the welding head 2 through the transducer 3 above the roller 1. Through the contact between the welding head 2 and the multi - layer fiber web 6, transfer the vibration energy to the multi - layer fiber web 6, causing the super - fine denier fibers in the multi - layer fiber web 6 to generate intense friction under the welding head 2. The temperature rises rapidly, causing the local melting of the super - fine denier fibers to obtain a molten material. The molten material penetrates through the multi - layer fiber web 6 to achieve the composite of the multi - layer fiber web 6, and obtain the glasses wiping cloth;

[0031] In this embodiment, the number of glue - free bonding operations is at least 1 time. Detect the glasses wiping cloth. If it is prone to shedding hair, then add the roller 1, transducer 3 and welding head 2, and perform secondary or tertiary glue - free bonding on the production line;

[0032] D. Cooling: Through the air knife 5 suspended in front of the transducer 3, blow air to the welding head 2 and the super - fine denier fibers below it for cooling, and accelerate the penetration of the molten material through the air flow, improving the composite effect of the multi - layer fiber web 6, avoiding the problem of bumps generated after the molten material accumulates and cools, improving the surface flatness of the glasses wiping cloth, thereby reducing the wear problem caused by wiping the glasses lenses and improving the performance of the glasses wiping cloth.

[0033] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
