Description

Ultrasonic wave cutting knife for non-metal mesh cloth

Technical Field

The utility model belongs to the technical field of the filter equipment production, concretely relates to ultrasonic wave divides cutter for non-metallic screen cloth.

Background

The screen cloth used for producing the filter is made of nonmetal materials, and the screen cloth needs to be cut before the filter is manufactured, so that the manufacturing requirement of the filter screen is met.

The width of cutting the non-metal mesh cloth is always the bottleneck in the industry, generally between 5-6 mm, and the precision is 0.5 mm. At present, the slitting width of the mesh with the smallest RUEF is 3mm, and the precision can reach 0.05 mm. Because the blade of the cutter is in direct contact with the ultrasonic slitting machine, the blade is accelerated to be worn under long-term high-frequency vibration, and the service life is shortened. In addition, the problem of inconvenient replacement of the cutter also exists, and the production efficiency is influenced.

The utility model discloses a realize like this: an ultrasonic slitting knife for non-metal mesh cloth comprises a knife holder, a knife rest, a pressing block, a spring and a blade; the pressing block is detachably arranged on the tool apron, the tool rest is limited by the pressing block so as to slide on the tool apron along a linear direction and is elastically connected with the tool apron through the spring, and the blade is arranged at the end part of the tool rest.

Further, the blade taper of the blade is 110 ° to 150 °.

Further, still include the clamp, a side edge of blade holder is provided with the bayonet socket of taking the retaining surface, the clamp sets up bayonet socket department.

Furthermore, the device also comprises a limiting block; the limiting block is detachably arranged on the cutter holder and limits the cutter rest.

Further, the tool rest further comprises a plurality of guide rods, the guide rods are arranged on the tool apron side by side, the tool rest is provided with guide holes matched with the guide rods, and the spring sleeves are arranged on the guide rods outside the guide holes.

Further, a sliding groove extending along a straight line is formed in the surface of one side of the cutter holder, the pressing blocks are arranged on the two sides of the sliding groove respectively, the cutter holder is arranged in the sliding groove, the pressing blocks are provided with limiting portions, bosses are arranged on the two sides of the cutter holder respectively, and the limiting portions are used for limiting the bosses in a one-to-one correspondence mode.

The utility model discloses the beneficial effect who brings is:

1. the utility model provides a cutter adopts the mode of direct change knife rest to realize carrying out the purpose of adjusting according to the screen cloth width, greatly reduced the change degree of difficulty, promoted tool changing efficiency.

2. The utility model provides a knife rest adopts the spring to cushion, has reduced the degree that causes the blade wearing and tearing because long-time high-frequency vibration when cutting.

3. The utility model provides a blade adopts the structure of the different tapering chamfers in both sides to reduce the unedged production of screen cloth incision department, improves and cuts precision and quality.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, the ultrasonic slitting knife includes a knife holder 1, a knife rest 6, a pressing block 7, a spring 5 and a blade 8; the pressing block 7 is detachably arranged on the tool apron 1, the tool apron 6 is limited by the pressing block 7 to slide on the tool apron 1 in a linear direction and is elastically connected with the tool apron 1 through the spring 5, and the blade 8 is arranged at the end part of the tool apron 6. In the process of ultrasonic slitting, because the existence of spring 5 for ultrasonic slitting machine all can form the buffering with knife rest 6 when vibrating at every turn, avoids the rigidity striking, thereby realizes reducing the purpose of 8 degree of wear of blade.

In an alternative embodiment, in order to satisfy the fixation of the ultrasonic cutting blade, the ultrasonic cutting blade further comprises a clamp 2, one side edge of the blade holder 1 is provided with a bayonet with a stop surface 9, the clamp 2 is arranged at the bayonet so as to arrange the blade holder 1 on the transverse shaft of the blade holder, and the stop surface 9 is in positioning contact with the stop surface on the transverse shaft, so as to fix the installation angle of the ultrasonic cutting blade.

In an alternative embodiment, the cutting edge taper of the blade 8 is 110 ° to 150 °, preferably 137.5 °. Through the structure, burrs can not occur when the blades 8 cut the mesh cloth, so that the cutting quality and precision are improved, and the ultrasonic splitting machine cannot be seriously scratched due to too sharp.

In an optional embodiment, the ultrasonic slitting knife further comprises a limiting block 3; the limiting block 3 is detachably arranged on the tool apron 1 and limits the tool rest 6.

In an optional embodiment, the ultrasonic slitting knife further comprises guide rods 4, five guide rods 4 are arranged on the knife holder 1 side by side, the knife rest 6 is provided with guide holes 6.2 matched with the guide rods 4, and the springs 5 are sleeved on the guide rods 4 outside the guide holes 6.2 in a one-to-one correspondence manner.

In an alternative embodiment, a sliding groove 1.1 extending along a straight line is formed in one side surface of the tool apron 1, the pressing blocks 7 are respectively arranged on two sides of the sliding groove 1.1, the tool rest 6 is arranged in the sliding groove 1.1, the pressing blocks 7 are provided with limiting portions 7.1, two sides of the tool rest 6 are respectively provided with bosses 6.1, and the limiting portions 7.1 limit the bosses 6.1 in a one-to-one correspondence manner. When the slitting width needs to be adjusted, only the pressing block 7 needs to be detached to enable the knife rest 6 to be in a free state so as to be taken out, and then the pressing block 7 is mounted after the knife rest 6 with proper thickness is replaced. Just so need not to demolish whole cutter and adjust, reduced the change degree of difficulty, improved change efficiency.
