Double applying bar slide
Technical field:
The utility model relates to the aid technical field of Sewing machines, refers in particular to fast, the measured double applying bar of the sewing matter slide of a kind of sewing speed.
Background technology:
At present, the sewing of wind coat waistband and skirt waistband generally uses the general industry Sewing machines, and general four procedures that divide of its manufacture craft: (1) is at first with the two-layer stitching in bottom surface, stay 5cm left and right sides opening, (2) from opening part with its turn-over, (3) will around the pleat line finish, (4) order button.But at present popular waistband is generally all than broad, if with common industrial sewing machine sewing, regardless of being with Gao Che or flatcar being arranged, when the first step is sewed up, need live two layers of cloth with hand and carry out feeding, to guarantee sutural unanimity, sewing speed is unsuitable too fast, and operating efficiency is lower; If during the sewing excessive velocities, be difficult to guarantee that the suture on both sides is parallel, the phenomenon of wrinkle also may appear in two layers of cloth, influences the outward appearance of waistband.
The utility model content:
The purpose of this utility model is exactly the deficiency that exists at prior art and provide that a kind of sewing speed is fast, the measured double applying bar of sewing matter slide.
To achieve these goals, the technical solution adopted in the utility model is: double applying bar slide, comprise that two are used for the slide that cloth passes, two slides go to upper and lower placement, have an angle between two slides, angle greater than 0 ° less than 90 °; Also comprise and be used for slide is installed in the connecting plate on the Sewing machines and prevents the reinforcement of slide move left and right, the base plate that is positioned at the slide of below is connected with connecting plate, reinforcement is positioned at the slide both sides, and reinforcement top is connected with the slide that is positioned at the top, and the reinforcement bottom is connected with connecting plate.
Described slide is a flat bar.
Described connecting plate is provided with and is used for the hole that bolt passes, and connecting plate is connected with the bottom of the slide that is positioned at the below.
Described connecting plate is connected by bolt with reinforcement.
Described angle greater than 10 ° less than 45 °.
Described angle is 20 °.
The port of export of two slides is in contact with one another.
The porch of described slide is provided with guide channel, and guide channel comprises bottom land and be positioned at the side plate of bottom land both sides that the base plate of bottom land and slide connects as one structure.
Further comprise a swash plate, swash plate is connected with the openend of guide channel, and swash plate and bottom land connect as one structure, and swash plate is downward-sloping with respect to bottom land.
The exit of described slide is provided with pressing plate, has a gap between pressing plate and the slide base plate, and pressing plate is parallel with the slide base plate.
The beneficial effects of the utility model are: after adopting the utility model, in the slide, cooperate improved two-needle sewing machine about the bottom surface two layers of cloth can being sent into, can once sew up two layers of cloth, because the guide function of slide, can guarantee that the waistband size of finishing is consistent with stitching, and surfacing, steady quality, attractive in appearance, improved sewing efficient, saved cost greatly, thereby increase economic efficiency.
Description of drawings:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is a vertical view of the present utility model.
The specific embodiment:
See Fig. 1,2,3, this is a better embodiment of the present utility model, double applying bar slide, comprise that two are used for the slide 1 that cloth passes, two slides 1 go to upper and lower placement, has an angle between two slides 1, angle is 20 °, also comprise the reinforcement 2 that is used for that slide 1 is installed in the connecting plate 3 on the Sewing machines and prevents slide 1 move left and right, the base plate that is positioned at the slide 1 of below is connected with connecting plate 3, reinforcement 2 is positioned at slide 1 both sides, and reinforcement 2 tops are connected with the slide 1 that is positioned at the top, and reinforcement 2 bottoms are connected with connecting plate 3 by bolt 7.
The port of export of two slides 1 is in contact with one another, and when the port of export of cloth from two slides 1 stretches out, can fit together.Wherein, described slide 1 is a flat bar.
The porch of described slide 1 is provided with guide channel 4, guide channel 4 comprises bottom land 4a and is positioned at the side plate 4b of bottom land 4a both sides, the base plate of bottom land 4a and slide 1 connects as one structure, and the effect of guide channel 4 is that the guiding cloth enters in the slide 1 phenomenon that makes cloth can not occur giving a discount.
The openend of guide channel 4 also is connected with a swash plate 5, swash plate 5 connects as one structure with bottom land 4a, swash plate 5 is downward-sloping with respect to bottom land 4a, and cloth is because the gravity effect is to be adjacent to bottom land 4a downwards, and the effect of swash plate 5 is the resistances that reduce between cloth and the bottom land 4a.
The exit of described slide 1 is provided with pressing plate 6, has a gap between the base plate of pressing plate 6 and slide 1, and pressing plate 6 is parallel with the base plate of slide 1, and the effect of pressing plate 6 is to make cloth be close to the base plate operation, guarantees that the cloth operation is smooth and easy.
When the utility model uses, connecting plate 3 is placed on the workbench of Sewing machines, by bolt connecting plate 3 is fixed on the workbench then, wherein, the port of export of slide 1 is near the pin position of Sewing machines, Sewing machines is provided with two eedles, interval between two eedles is identical with the exit width of slide 1, and two cloths are entered by the porch of upper and lower slide 1 respectively, are drawn by the port of export, then by two eedles and needlework, the dual-side of two-layer cloth is stitched together.
Certainly, the embodiment of the above, it is better embodiment of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
