Stomata connection, the guide pipe are connected to extraneous gas source.
The setting of the structure, so that the better tightness of the connection of cushion block and extraneous gas source, facilitates extraneous gas source quickly to lead
Enter into cushion block, improves the fluency of sewing machine operation.
In the anti-pollution structure of above-mentioned sewing machine, there is inclined mounting surface, the cushion block on the looper take-up housing
Bottom surface can fit with mounting surface.
The setting of the structure, enables cushion block to be preferably arranged on looper take-up housing, further improves cushion block and sets
The stability set.
In the anti-pollution structure of above-mentioned sewing machine, the cushion block and looper take-up housing are integrally formed.
The setting of the structure further improves the stability of anti-pollution structure so that the setting of cushion block is more stable.
In the anti-pollution structure of above-mentioned sewing machine, the side wall of the looper take-up housing is equipped with cover board, the cushion block with
Cover board is integrally formed.
The setting of the structure, so that the setting of cushion block does not influence the structure of looper take-up housing, thus the setting of anti-pollution structure
Enhanced convenience and stabilization.
In the anti-pollution structure of above-mentioned sewing machine, sewing machine further includes the looper sliding block being arranged in looper take-up housing,
The looper slide bar is threaded through on looper sliding block.
The setting of the structure, so that the gas that venthole flows out on cushion block can also will be between looper slide bar and looper sliding block
Dust is blown off elsewhere.
Compared with prior art, the anti-pollution structure of this sewing machine has the advantage that
1, by setting cushion block, and offer on cushion block the venthole being connected to extraneous gas source, can by looper slide bar and
Dust between looper take-up housing either lubricating oil is blown off elsewhere, so that dust is not fallen out in looper slide bar and curved
Between needle take-up housing, the normal operation of looper slide bar is protected
2, gasket inner groovy angle setting so that venthole blowout gas is generated on looper slide bar one downwards
Active force, the active force can be preferably by the lubricating oil flow downs on looper slide bar, so that lubricating oil will not be sliding with looper
The movement of bar and be thrown to seam platform come up.
