Description

Technical Field

[0001] The utility model belongs to the technical field of production and cutting of sealing packings, in particular to a cutting device for production of sealing packings. Background Art

[0002] Packing is also called sealing filler. It is usually woven from softer threads. The cross-sectional area is usually square, rectangular or round. The strips are filled in the sealing cavity to achieve sealing. The packing seal was first used to plug cotton and linen fibers in the leakage channel to prevent liquid leakage. It was mainly used as a shaft seal for water-lifting machinery. With the continuous emergence of new materials, the packing structure has also changed greatly, which will undoubtedly promote the wider application of packing seals. The materials used as packing should have the following characteristics: certain elasticity and plasticity. When the packing is axially compressed, it can generate a large radial compression force to obtain a seal. Since the existing packing has a certain elasticity, it will expand to both sides when squeezed, resulting in continuous cutting. Therefore, it is very important to obtain a cutting device for packing production that overcomes the above defects. Utility Model Content

[0005] Preferably, the height of the blade block is greater than the height of the packing.

[0006] According to the above technical solution, since the packing will be deformed due to its own elasticity when being cut, the knife block should be longer than the height of the packing to increase the cutting efficiency.

[0007] As a preferred embodiment of the above, the clamping assembly further comprises a reinforcing connecting rod, and the reinforcing connecting rod is hinged to the support frame and the blade block respectively. The three hinges of the second connecting rod are not collinear.

[0024] Referring to the accompanying drawings, the utility model adopts the following technical scheme: a cutting device for packing production, comprising a workbench 1, a wire inlet 101 is provided on the workbench 1, a downwardly concave working groove 102 is provided on the workbench 1 at the bottom of the wire inlet 101, and a cutting mechanism 2, wherein the cutting mechanism 2 comprises a support frame 201 fixed on the workbench 1, a first cylinder 202 is fixed on the support frame 201, an output end of the first cylinder 202 passes through the support frame 201 and is fixedly connected to a first cross bar 203, and both ends of the first cross bar 203 are connected to clamping components arranged oppositely;

[0025] Each of the clamping assemblies comprises a first connecting rod 204 hinged at the end of the first cross bar 203, a second connecting rod 205 is hinged at the outer end of each of the first connecting rods 204, the middle part of each of the second connecting rods 205 is hinged to the support frame 201, a knife block 206 is hinged at the outer end of each of the second connecting rods 205, the working groove 102 is located on both sides of the wire inlet 101, guide rails 207 are fixed, a groove 209 for the guide rail 207 to pass through is provided on the knife block 206, the height of the groove 209 is greater than the height of the guide rail 207, and the knife block 206 is at least partially located in the working groove 102 during cutting.

[0026] Preferably, the height of the blade block 206 is greater than the height of the packing 5 .

[0027] According to the above technical solution, since the packing 5 will be deformed due to its own elasticity when being cut, the blade block 206 should be longer than the height of the packing 5 to increase the cutting efficiency.

[0028] As a preferred embodiment of the above, the clamping assembly further comprises a reinforcing connecting rod 208, and the reinforcing connecting rod 208 is respectively hinged on the support frame 201 and the blade block 206.
