Abstract
The invention provides a big presser foot of a bag opening machine, and belongs to the technical field of sewing machines. The big presser foot solves the problem that the big presser foot of the traditional bag opening machine enables fabric to be worn in the using process, thus the beautiful appearance is influenced. The big presser foot of the bag opening machine is arranged on a sewing platen and comprises a mounting plate which is arranged on the platen and can slide in a reciprocating way and a presser foot assembly articulated on the mounting plate, wherein the lower part of the mounting plate is fixedly connected with a platy compression board, and the compression board is attached to the surface of the platen and positioned right below the presser foot assembly. The big presser foot of the bag opening machine can fix the fabric between the presser foot body and the compression board, enables the fabric to be maintained to be static relative to the big presser foot and movable relative to the sewing platen, reduces the friction between the fabric and the sewing platen to the maximum extent, and guarantees and improves the sewing quality of the fabric.
Description
Technical field
The invention belongs to the sewing machine technique field, relate to a kind of big presser feet of big presser feet, particularly a kind of bag-opening machine.
Background technology
Bag-opening machine plays an important role in modern clothing production as a kind of clothes process equipment.In existing technology, the sewing platen of bag-opening machine is provided with the big presser feet of an auxiliary sewing, comprises presser feet installing plate, presser feet arm, presser feet body.The presser feet installing plate is used for fixing installs the presser feet arm, and the presser feet arm is used to connect presser feet body and presser feet installing plate, drives the presser feet body simultaneously and lifts and press down on carrying out, and operating personnel can make presser feet move to correct position and push down cloth by hand-held presser feet installing plate.
When bag-opening machine is worked, operating personnel move the presser feet installing plate, big presser feet is advanced in face of operating personnel, the presser feet body upwards lifts, after cloth was put into presser feet body below, the presser feet body pressed down, with cloth presser on the sewing platen surface, big then presser feet is pressing cloth to draw back to the eedle operating position, makes.In sewing feeding process, big presser feet is pressing cloth to make along with eedle that fore-and-aft direction moves on the sewing platen surface, at this moment, because the presser feet body has applied an active force cloth has been pressed down, cause existing a pressure between cloth and the sewing platen surface, and the mobile meeting of cloth makes generation friction between cloth and the sewing platen surface, when the time that such friction continues is longer, can produce the friction infringement that is difficult to remedy to some clothes, cause the decline of cloth sewing quality, and then influence attractive in appearancely, even can the economic benefit of clothes production enterprise be exerted an influence.
Summary of the invention
The objective of the invention is to have the problems referred to above, proposed a kind ofly can reduce cloth and sewing platen surface friction, improve the big presser feet of the bag-opening machine of sewing quality at existing technology.
Purpose of the present invention can realize by following technical proposal: a kind of big presser feet of bag-opening machine, be arranged on the sewing platen of bag-opening machine, comprise the installing plate of being located on the sewing platen that can do reciprocal translation gliding and the presser foot component that is articulated on the described installing plate, it is characterized in that, be connected one in described installing plate bottom and be tabular deposited plate, described deposited plate fits in described sewing platen surface, and be positioned at described presser foot component under.
The big presser feet of this bag-opening machine can be when bag-opening machine be made with cloth presser between presser feet body and deposited plate, owing to deposited plate can be along with the motion campaign of big presser feet, cloth is in sewing feeding process, can directly not contact with the sewing platen surface, so cloth can not produce friction with the sewing platen surface, thereby reduced the generation of friction infringement.
In the big presser feet of above-mentioned bag-opening machine, described deposited plate is the strip shape elastic plate.The strip shape elastic plate can make and apply board member adapts to working environment after installation ability enhancing.
In the big presser feet of above-mentioned bag-opening machine, described deposited plate comprises connecting portion, arc sections and elongated horizontal part, and described deposited plate is a connecting portion with the position that installing plate is connected mutually, the arc sections two ends are connecting connecting portion and horizontal part respectively, and the one side of horizontal part fits with the sewing platen surface.After regulating the suitable position of applying plate, by being bolted on the installing plate, deposited plate can keep relative static with big presser feet, can be synchronized with the movement with big presser feet.Arc sections makes connecting portion with respect to lifting on the horizontal part, conveniently is connected with installing plate.
In the big presser feet of above-mentioned bag-opening machine, be positioned on the described sewing platen on the position of described deposited plate outer ledge and be fixed with the protective plate that is long strip-board shape that parallels with the platen of sewing, have the gap of passing through for described deposited plate between described protective plate and the sewing platen.When big presser feet moved, the outer ledge that applies the horizontal part of plate stretched into and can prevent to apply upwarping suddenly that plate may occur at work in the protective plate and wait some accidents to take place.
In the big presser feet of above-mentioned bag-opening machine, described presser foot component comprises the presser feet arm and is connected in the presser feet body of presser feet arm one end that the hinge point of described presser foot component and described installing plate is on described presser feet arm.
In the big presser feet of above-mentioned bag-opening machine, described installing plate is provided with cylinder, and the other end of the piston rod outer end of described cylinder and above-mentioned presser feet arm is hinged.
In the big presser feet of above-mentioned bag-opening machine, the lower surface of described presser feet body has the friction member that is provided with along above-mentioned big presser feet moving direction.The purpose that adds friction member is, improves the friction environment of sewing and presser feet, reduces contact area, strengthens pressure, is beneficial to that sewing is straight steadily to be moved.
In the big presser feet of above-mentioned bag-opening machine, the rubber strip that described friction member is.
Compared with prior art, the big presser feet of this bag-opening machine can be with between cloth independent stationary presser feet body and the deposited plate, and do not need to be pressed on the sewing platen, make between cloth and the big presser feet and keep relative static conditions, but keep relative-movement state with the sewing platen, friction between cloth and the sewing bedplate surface is reduced as far as possible, guarantee and improved the sewing quality of cloth.
