Description

Novel ultrasonic ring cutter

Technical Field

The utility model relates to an ultrasonic vibration equipment technical field specifically is a novel ultrasonic wave girdling sword.

Background

In the prior art, the material of the filtering membrane is generally non-woven fabric, PP cotton and the like, and a cutter with an annular blade is required for producing the annular filtering membrane, but due to the particularity of the material, the cutter is difficult to push by using an air cylinder, the filtering membrane is cut in an extrusion mode, so that the production field generally adopts an ultrasonic vibration mode, and the vibration cutting of the filtering membrane is realized in a mode of vibrating the contact surface of the cutter and the filtering membrane. However, the blade is not continuously vibrated during the vibration process, which is easy to generate heat, and is especially easy to adhere to the filter membrane after cutting, thereby affecting the normal cutting of the filter membrane next time, which is not favorable for automatic production and has low production efficiency.

In order to solve the problems, the scheme is developed accordingly.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to overcome prior art's not enough, provide one kind and can prevent the adhesive novel ultrasonic wave ring cutter of filtration membrane and cutting edge.

(II) technical scheme

in order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a novel ultrasonic ring cutting knife comprises a ring cutting knife, wherein the ring cutting knife is hollow inside and open at the bottom, and a knife edge is integrally formed at the bottom end of the ring cutting knife and is annular; the extrusion plate is connected with the interior of the ring cutter through a spring and is surrounded by the annular cutting edge; the extrusion plate is located on the outer side of the ring cutter in a normal state, and under the action of extrusion force, the extrusion plate can be retracted into the ring cutter in combination with the acting force of the spring.

Preferably, the extrusion plate is provided with a first channel and a second channel which are closed at one ends and a third channel which is closed at two ends, and the first channel and the second channel are communicated through the third channel.

Preferably, the ring cutter comprises a cutter holder, a cutter head and a connecting seat; external threads are arranged on the outer sides of the cutter holder and the cutter head; the inner side of the connecting seat is provided with an internal thread which can be in threaded connection with the external thread.

(III) advantageous effects

After the technical scheme is adopted, compared with the prior art, the utility model, possess following advantage: the utility model relates to a novel ultrasonic wave cutting ring, through setting the cutting ring to inside cavity, the open structure in bottom, and set up the outside that lies in the cutting ring under the normality, and through the inside stripper plate that links to each other of spring and cutting ring, so, after the cutting is accomplished, because the recovering action of spring, can pop out the inside of cutting ring earlier with the stripper plate, like this will be with the mode realization separation of filter membrane with outside top of bonding on the cutting edge, avoid the cutting ring to bond with the filter membrane after the cutting, thereby effectively improve the efficiency of production.

FIG. 2 is an exploded view of the present invention;

FIG. 3 is a schematic view of the structure of the middle knife holder of the present invention;

Fig. 4 is a schematic structural view of the middle extrusion plate of the present invention.

In the figure: the cutting device comprises a ring cutter 1, a cutter holder 11, a cutter head 12, a connecting seat 13, a blade 2, an extrusion plate 3, a spring 4, a channel I5, a channel II 6, a channel III 7, an internal thread 8 and an external thread 9.

Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-4: the utility model provides a novel ultrasonic wave rotary cutter, includes rotary cutter 1, and its inside cavity and bottom are opened, and rotary cutter 1's bottom integrated into one piece has cutting edge 2, and cutting edge 2 is the annular. And the extrusion plate 3 is connected with the inner part of the ring cutter 1 through a spring 4, and is surrounded by the annular blade 2. The extrusion plate 3 is positioned at the outer side of the ring cutter 1 under the normal state, and can retract into the ring cutter 1 by combining the acting force of the spring 4 under the action of the extrusion force.

The extrusion plate 3 is normally located outside the ring-cutting knife 1, and its position is shown in fig. 1.

The use process is that the raw material of the filtering membrane is firstly placed on a mould, the circular cutting knife 1 is descended until the knife edge 2 is contacted with the raw material of the filtering membrane, and at the moment, the extrusion plate 3 is extruded and can be retracted into the hollow interior of the circular cutting knife 1 in combination with the acting force of the spring 4; open ultrasonic vibration device, under the vibration, the annular filtration membrane of mould cutting department can be combined to ring cutter 1, rises the back again with ring cutter 1, because spring 4's recovery effect, can pop out the inside of ring cutter 1 with stripper plate 3 earlier, will be like this can be with the filtration membrane separation of bonding on cutting edge 2.

after the ring-cutting knife 1 is used, the problem that the cutting edge 2 of the ring-cutting knife 1 is difficult to separate after being adhered to a filtering membrane can be avoided, and the ring-cutting knife 1 cannot influence the process of automatic production, so that the production efficiency can be greatly increased.

In the vibration process, the extrusion plate 3 is also contacted with the filtering membrane, but the contact area of the extrusion plate 3 and the filtering membrane is small, so the extrusion plate is not easy to be adhered with the filtering membrane. Namely: the extrusion plate 3 is provided with a first channel 5 with one closed end, a second channel 6 and a third channel 7 with two closed ends, and the first channel 5 and the second channel 6 are communicated through the third channel 7.

Wherein passageway one 5 can regard as into water end, lets in the water source (also can let in the better liquid nitrogen of cooling effect, liquid ammonia etc. but the cost is higher), and passageway two 6 is as going out the water end to can cool off in that stripper plate 3 is inside.

The ring cutter 1 comprises a cutter holder 11, a cutter head 12 and a connecting seat 13. The outer sides of the tool apron 11 and the tool bit 12 are both provided with external threads 9. The inner side of the connecting seat 13 is provided with an internal thread 8, and the internal thread 8 can be in threaded connection with an external thread 9.

Because the cutting edge 2 of considering the cutting ring 1 uses the back for a long time, needs to be changed, will increase the cost like this, especially the cutting ring 1 of this scheme is equipped with the structure of spring 4, stripper plate 3, and the manufacturing process is also loaded down with trivial details relatively, and the cost is higher relatively (compare in large-scale production back, its cost still can be ignored), so the cutting edge 2 of cutting ring 1 separates with blade holder 11, just so only need change cutting edge 2, reduces the spending of cost. This embodiment adopts both to set up threaded connection's mode, installs, dismantles, and the process is more simple and convenient.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the protection scope must be determined by the scope of the claims.
