Description

Welding device for dust filter element

Technical Field

The utility model relates to an ultrasonic bonding equipment field especially relates to a dust filters welding set for core.

Background

The dust filter core is often used for filtering solid tiny particle, generally divide into board-like and cylinder structure, uses the cylinder structure as an example, and it is hollow column with filter media head and the tail butt joint convolution formation, in order to guarantee the shaping structure, still can set up the bandage and carry out the outer lane fixed. The connected mode of traditional bandage and filter media is for carrying out the adhesion with glue, but glue easily melts under the condition of being heated and loses viscidity, and some adopt rivet connection's mode in addition need punch on the filter media, destroys the filter core structure easily, and the processing difficulty has increased the fixed degree of difficulty of bandage especially because the fold structure of filter media itself. Therefore, a set of special equipment is needed to facilitate production.

SUMMERY OF THE UTILITY MODEL

Based on it, an object of the utility model is to provide a welding set for dust filter element adopts the ultrasonic bonding mode, cooperates special tool, realizes the reliable welding of filter media and bandage.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a dust filters welding set for core, wherein, the dust filters the core and includes fold filter media and braid over braid, welding set includes the base, fixed block and ultrasonic bonding tool, the ultrasonic bonding tool is located one side of fixed block, and both all are located the top of base, be provided with the sawtooth groove unanimous with the shape of fold filter media on the base, be provided with on the fixed block with sawtooth groove complex sawtooth arris, the fold filter media pastes and puts on the base, the fixed block pushes down and agrees with the base, press from both sides the fold filter media in wherein simultaneously, the braid over braid is placed on the fold filter media, the ultrasonic bonding tool is down to be contacted with the braid over braid, thereby weld.

Particularly, a stepped groove is formed in the contact surface of the top of the ultrasonic welding head and the transducer, and the stepped groove is used for reducing vertical amplitude errors.

In particular, the ultrasonic horn is formed with horizontal grooves for reducing lateral amplitude errors.

In particular, the length of the base and the fixing block is consistent, and the width of the fixing block does not exceed 1/2 of the width of the base.

In particular, a driving handle is arranged on the fixed block.

To sum up, the beneficial effects of the utility model are that, compared with the prior art, the special tool of welding set design is fixed to the fold filter media for the dust filter core to cooperation ultrasonic bonding tool realizes linking firmly of braid over braid and filter media, and welding quality is stable, pleasing to the eye, is difficult for droing, and the specificity is strong.

Drawings

Fig. 1 is a schematic structural diagram of a welding device for a dust filter element provided by an embodiment of the present invention.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides a welding device for a dust filter element, which uses an ultrasonic welding method to complete welding, wherein the ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded, and the surfaces of the two objects rub against each other under pressure to form fusion between molecular layers. Specifically, high frequency electrical energy is converted into mechanical motion of equal frequency by a transducer, and vibrational energy is transferred to the horn and further to the joint of the work pieces to be welded, where it is frictionally converted into thermal energy to melt the plastic.

Wherein, the dust filter core includes fold filter media 9 and braid over braid 10, welding set includes base 1, fixed block 2 and ultrasonic bonding tool 3, ultrasonic bonding tool 3 is located one side of fixed block 2, and both all are located base 1's top, be provided with the sawtooth groove 4 unanimous with fold filter media 9's shape on the base 1, be provided with on the fixed block 2 with sawtooth groove 4 complex sawtooth arris 5, fold filter media 9 pastes and puts on base 1, fixed block 2 pushes down and agrees with base 1, press from both sides fold filter media 9 wherein simultaneously, braid over braid 10 is placed on fold filter media 9, ultrasonic bonding tool 3 contacts with braid over braid 10 down, thereby weld.

A stepped groove 6 is formed in the contact surface of the top of the ultrasonic welding head 3 and the transducer, and the stepped groove 6 is used for reducing vertical amplitude errors. The ultrasonic welding head 3 is provided with a horizontal groove 7, and the groove 7 is used for reducing transverse amplitude errors. Therefore, the amplitude uniformity of the center and two sides of the welding head can be ensured, the error is reduced within 3 microns, and the welding quality is ensured.

The length of the base 1 is consistent with that of the fixed block 2, the width of the fixed block 2 does not exceed 1/2 of the width of the base 1, and a welding area is reserved, so that the ultrasonic welding head 3 is matched with the base 1, and the woven belt 10 is conveniently welded with the folded edge of the folded filter material 9.

Be provided with drive handle 8 on fixed block 2, make things convenient for fixed block 2 drive from top to bottom.

To sum up, this welding set for dust filter element designs special tool and fixes the fold filter media to cooperation ultrasonic bonding tool realizes linking firmly of braid over braid and filter media, and welding quality is stable, pleasing to the eye, is difficult for droing, and the specificity is strong.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
