Description

Air gun type Non-woven fabric ultrasonic wave cutter head

Technical field

The utility model relates to a kind of for cutting the device of nonwoven, relates in particular to a kind of air gun type Non-woven fabric ultrasonic wave cutter head.

Background technology

Utilizing ultrasonic wave cutting nonwoven (Nonwoven cloth) has been the cutting means of industry-wide adoption.Ultrasonic wave incision principle is to utilize the acoustic energy of vibration to drive non-woven fabrics fiber molecule to do severe thermal motion, will be cut partial melting.Compare with mechanical shearing cutting, there is no mechanical shearing in ultrasonic wave cutting process, do not need fixing nonwoven, the phozy thorn of otch, can automatic trimming.During cutting, ultrasonic cutter bit (ultrasonic amplifier), is placed in the top of nonwoven, the contact of discord nonwoven; Cutting edge is placed in the below of nonwoven, touches nonwoven; Acoustic energy gathers on cutting edge, Fast Heating contact with cutting edge fibr tissue.

But, in actual use, to find, nonwoven is not when taking fixing operation, and the uniformity of cutting is difficult to assurance, and, on whole piece otch, local melting is too early, and local melting is excessively slow; Too early the part of fusing by continuous heating until at the latest the position of fusing also cut off completely; On the one hand, cause otch inhomogeneous, affect product quality, on the other hand, the part of crossing late fusing has extended whole piece otch break time, has lowered production efficiency,

As mentioned above, as long as solved the nonsynchronous problem of each position fusing time of otch, otch uneven with and break time long problem be readily solved too.By analysis, cause that the nonsynchronous reason of each position fusing time of otch is can not touch completely on cutting edge on otch everywhere, this is because nonwoven is actually irregular, and between cutting edge, exists gap not contact completely.In view of this, the utility model proposes a kind of air gun type Non-woven fabric ultrasonic wave cutter head, to address the above problem.

Utility model content

The purpose of this utility model is to provide a kind of air gun type Non-woven fabric ultrasonic wave cutter head, solves the problem that on nonwoven otch, each position can not synchronously be melted.

In order to reach above-mentioned purpose, the technical solution of the utility model is as follows.

A kind of non-air gun type Non-woven fabric ultrasonic wave cutter head, comprises ultrasonic cutter bit, collector box, sealing gasket, resilient plug, joint and source of the gas; On described ultrasonic cutter bit, there is dovetail groove; Described collector box has inner chamber and is divided into two sections, and the big up and small down funnel-form of epimere forms top, and it is following that hypomere is up-small and down-big horn-like formation; Described sealing gasket is contained in dovetail groove, and between ultrasonic cutter bit and collector box; Described resilient plug is square, has spray chamber, and embeds in collector box; Described jiont treatment is set up sealing ring and is connected on appendix on collector box and between collector box; Described appendix is connected to source of the gas.

Wherein, said collector box has floor, and floor is provided with up big and down small opening.

Wherein, said sealing gasket, resilient plug adopt silica gel to make.

Adopt after the technical solution of the utility model, origin is to collector box air feed, gas is assembled in the high pressure chest of collector box, pressure increases and ejects by spray chamber, and the gases at high pressure that eject are applied on the nonwoven of ultrasonic cutter bit below, and nonwoven is pressed on cutting edge, guarantee that nonwoven fully contacts with cutting edge, eliminated the gap between nonwoven and cutting edge, can guarantee fusing simultaneously everywhere on otch, cut off simultaneously.

Below in conjunction with accompanying drawing, further set forth the technical solution of the utility model with embodiment.

The specific embodiment

Refer to Fig. 1, the air gun type Non-woven fabric ultrasonic wave cutter head of the present embodiment comprises ultrasonic cutter bit 10, collector box 20, sealing gasket 30, resilient plug 40, joint 52 and source of the gas 54; On ultrasonic cutter bit 10, there is dovetail groove 11.Collector box 20 has inner chamber and is divided into two sections, and the big up and small down funnel-form of epimere forms top 21(and sees Fig. 6), hypomere is the up-small and down-big following 22(of horn-like formation and sees Fig. 6); Described sealing gasket 30 is contained in dovetail groove 11, and between ultrasonic cutter bit 10 and collector box 20; Described resilient plug 40 is square (see figure 4), adopts silica gel to make, and has spray chamber 13, and embeds in collector box 20 and form interference fit; Joint 52 is arranged on to be set up sealing ring 51 and is connected on appendix 53 on collector box 20 and between collector box 20; Appendix 53 is connected to source of the gas 54.Structure after Fig. 2 has further illustrated the present embodiment to assemble.

Fig. 6 has illustrated three cross section, place a, b, the c of collector box 20, and the screw thread on a of cross section is for jointing 52; The top 21 of cross section b is high pressure chest sides, following 22 and resilient plug 40 form interference fit; On cross section c signal floor 23, have opening 231, air-flow is distributed to whole collector box 20 high pressure chests everywhere through opening 231.

During work, origin is supplied with pressure-air by appendix 53, joint 52 to collector box 20.The pressure-air entering in collector box 20 is full of whole high pressure chest 12 through the opening 231 of each floor 23, and its pressure further increases.Air after supercharging acts on nonwoven by spraying front ejaculation, and nonwoven is pressed onto on cutting edge, has eliminated the gap between nonwoven and cutting edge, guarantees fusing simultaneously everywhere on otch, cuts off simultaneously.Compare with existing ultrasonic wave cutter head, the otch that the present embodiment cuts out is evenly smooth, and clipping time is short, and both having improved product quality has and accelerated production efficiency.
