The utility model relates to the technical field of Sewing machines, especially a kind of drive unit of mechanism for lifting pressre of sewing machine is related to, comprise the electromagnet be fixedly installed in the installation cavity of head of sewing machine, the middle part of lifting depression bar is articulated with on the hinged seat in installation cavity, the one end of lifting depression bar is connected with foot lifting mechanism, the other end lifting depression bar is hinged with roller, and roller rolls with the end of the mandrel of described electromagnet and is connected.Advantage is: utilize the other end lifting depression bar to be hinged with roller, roller rolls with the end of the mandrel of described electromagnet and is connected, make resistance between each part little, and production efficiency is also high, effectively reduce the power output of band motor magnet, and the design defect restrained because lifting depression bar causes foot lifting mechanism card to pause or stuck phenomenon.
Description
Technical field
The utility model relates to the technical field of Sewing machines, especially relates to a kind of drive unit of mechanism for lifting pressre of sewing machine.
Background technology
Foot lifting mechanism is extremely common on Sewing machines, it is a common mechanism, but its drive unit there will be some faults when using on Sewing machines, this drive unit is lift depression bar by the solenoid actuated be fixedly installed in the installation cavity of head of sewing machine, this one end of lifting depression bar is connected with foot lifting mechanism, the other end is then connected with the mandrel of electromagnet, the friction ratio of this structure is larger, after Long-Time Service, foot lifting mechanism card can be caused to pause or stuck phenomenon, and the degree of wear of part also very large, for cost of investment very unfavorable of equipment, also having a kind of is adopt to be fixed with bearing pin on a side of lifting depression bar end, bearing pin is arranged with pulley, this pulley slides on mandrel, this kind of more last scheme of scheme decreases the wearing and tearing of part, but foot lifting mechanism still there will be stuck or blocks the phenomenon of timing, after long-term work, the comparatively front a kind of scheme of the phenomenon that stuck or card pauses is even more serious.
Summary of the invention
For the deficiency that above-mentioned prior art exists, it is little that the purpose of this utility model is to provide resistance between a kind of each part, and production efficiency is also high, effectively reduce the power output of band motor magnet, and the design defect restrained because lifting depression bar causes foot lifting mechanism card to pause or the drive unit of the mechanism for lifting pressre of sewing machine of stuck phenomenon.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of drive unit of mechanism for lifting pressre of sewing machine, comprise the electromagnet be fixedly installed in the installation cavity of head of sewing machine, the middle part of lifting depression bar is articulated with on the hinged seat in installation cavity, the one end of lifting depression bar is connected with foot lifting mechanism, the other end lifting depression bar is hinged with roller, and roller rolls with the end of the mandrel of described electromagnet and is connected.
The utility model is set to further: described in lift depression bar the other end concrete structure that is hinged with roller be: the sidewall of roller is provided with mounting groove, roller is provided with the bearing pin running through both ends of the surface and mounting groove, the described other end lifting depression bar is provided with the hinge hole matched with bearing pin, and this end lifting depression bar is inserted in mounting groove and this end and is articulated with on the bearing pin in mounting groove.
The utility model is set to further: described in lift depression bar be L shape, the bending part lifting the L shape of depression bar is articulated with on the hinged seat in described installation cavity.
The utility model is set to further: described bending part and the described middle part of lifting on depression bar of lifting between one end that depression bar is hinged with roller are provided with the installing hole of the knee control push rod installing Sewing machines.
The utility model is set to further: described bending part is lifted lifting on depression bar between one end that depression bar is connected foot lifting mechanism arrange at least one connecting hole with described.
By adopting technique scheme, the technique effect that the utility model reaches is: utilize the other end lifting depression bar to be hinged with roller, roller rolls with the end of the mandrel of described electromagnet and is connected, make resistance between each part little, and production efficiency is also high, effectively reduce the power output of band motor magnet, and the design defect restrained because lifting depression bar causes foot lifting mechanism card to pause or stuck phenomenon.
