Abstract
The utility model relates to the field of sewing devices, in particular to a back drag wheel lifting mechanism of a double-needle machine. The back drag wheel lifting mechanism lifts a drag wheel through a pedal plate and is time-saving, labor-saving and very convenient to operate. The technical scheme is that the back drag wheel lifting mechanism of the double-needle machine comprises a pressing rod guide frame and a guide plate, wherein a guide groove is arranged on the guide plate, an uplifting assembly is arranged on the pressing rod guide frame, the pressing rod guide frame is fixedly connected with a back drag wheel assembly through a screw, and the screw is arranged in the guide groove. The back drag wheel lifting mechanism further comprises a connecting rod located on the outer side of the guide plate, the screw is an axial screw, the axial screw is arranged on a rectangular chute of the connecting rod, the upper end of the connecting rod is connected with a back drag wheel lifting crank, and an action section of the back drag wheel lifting crank is movably connected with a pull rod. The pull rod is movably connected with a crank lever, the fixed end of the crank lever is hinged to a back cover plate, and the action end of the crank lever is connected with the pedal plate through a chain.
Description
One, technical field:
The utility model relates to the sewing device field, is specifically related to tugboat hoisting mechanism behind a kind of double needle machine.
Two, background technology:
Drag machine (201020542231.2) behind the crosspointer at present, it is to drag spanner manually to realize after leaning on that back tugboat promotes, the operative employee is when work, possible both hands are all in busy other work, if promote the back tugboat, the lifting of tugboat had so just reduced operating efficiency after other the work of just must stopping was finished, and drag spanner after need shaking when promoting the back tugboat, relatively effort.
Three, utility model content:
The purpose of this utility model provides tugboat hoisting mechanism behind a kind of double needle machine, and the lifting of tugboat was increased work efficiency after it can be finished by foot pedal, reduces operative employee's labour intensity.
For achieving the above object, the technical solution adopted in the utility model is: tugboat hoisting mechanism behind a kind of double needle machine, comprise compressor arm saddle and guide plate, described guide plate is provided with gathering sill, described compressor arm saddle is provided with lifts assembly, the compressor arm saddle is connected by screw with back tugboat assembly, screw is arranged in the gathering sill, it is characterized in that: also comprise the connecting rod that is positioned at the guide plate outside, described screw is axle position screw, described axle position screw is arranged on the rectangle chute of connecting rod, the upper end of described connecting rod is connected with back tugboat lift crank, and action section and the pull bar of described back tugboat lift crank flexibly connect, and described pull bar and crank levers flexibly connect, the stiff end of crank levers is hinged to be arranged on the back shroud, and its motion end is connected with pedal by chain.
Connect by bearing pin between described back tugboat lift crank, pull bar and the crank levers.
Described chain is the melon seeds chain.
Compared with prior art, the advantage and the effect that the utlity model has are as follows: the utility model passes through pin
The lifting of tugboat after pedal is finished not only saves time but also laborsaving, and is easy to operate.
Four, description of drawings:
Fig. 1 is structure chart of the present utility model;
Among the figure: 1-guide plate, 2-gathering sill, 3-compressor arm saddle, 4-axle position screw, 5-connecting rod, tugboat lift crank behind the 6-, 7-pull bar, 8-crank levers, 9-chain, 10-pedal, 11-back shroud.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is further elaborated:
Referring to Fig. 1: tugboat hoisting mechanism behind a kind of double needle machine, comprise compressor arm saddle 3, guide plate 1 and back tugboat assembly, described guide plate 1 is provided with gathering sill 2, described compressor arm saddle 3 is provided with lifts assembly, compressor arm saddle 3 is connected by screw with back tugboat assembly, screw is arranged in the gathering sill 2, also comprise the connecting rod 5 that is positioned at guide plate 1 outside, described screw is axle position screw 4, described axle position screw 4 is arranged on the rectangle chute of connecting rod 5, the upper end of described connecting rod 5 is connected with back tugboat lift crank 6, motion end and the pull bar 7 of described back tugboat lift crank 6 are hinged by bearing pin, and described pull bar 7 is hinged by bearing pin with crank levers 8, and the stiff end of described crank levers 8 is hinged to be arranged on the back shroud 11, its motion end is connected with pedal 10 by melon seeds chain 9.
Back shroud is provided with the automatic presser foot lifter mechanism (patent No.: in the time of 200520079398.9), be equipped with axle at back shroud 11, axle is provided with the presser foot lifter lever, its function is similar to the crank levers 8 in the utility model, like this utility model can with its combination, with the whole replacement of the electromagnet assembly on the crank-operated end in the original structure, namely can provide power to two cover mechanisms on a pedal 10.
The utility model is in use by trampling pedal, pedal drives the melon seeds chain and drives crank levers drive pull bar, drive back tugboat lift crank again by pull bar and drive a connecting rod drive axle position screw, axle position screw band action-oriented plate, guide plate drive compressor arm saddle drive back tugboat and promote.
