Background technology
The clothes of a finished product (comprising clothes and trousers) all are to be processed through different cuttings and splicing by cloth; And original cloth basically all has burr through after cutting out; For the clothes that make finished product more neat and artistic; Carry out downward crimping earlier adding the one side that has burr on need be cloth man-hour, and then carry out tangent line through presser feet and make.At present the crimping of cloth burr all is to be manual crimping by the processor the forefathers that step on the line, and efficient is low, and width is inconsistent easily before and after the flange that rolls out, and tangent line is not straight easily yet, causes the crudy of product not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of automatic hemming device that can improve the Sewing machines that is installed in the presser feet front of working (machining) efficiency and quality greatly.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of automatic hemming device of Sewing machines; Comprise " U " type guider of at least one transverse opening, be connected with the pressurized gas system that the burr that can promote cloth carry out " U " type crimping on the described guider.
Described " U " type guider is one; Described " U " type guider comprise transverse opening " U " type first location-plate and to first guide plate of the described first location-plate inner bending; The bottom of described first guide plate is fixedly connected with the bottom of described first location-plate; Form first " U " type guide channel of a transverse opening between described first guide plate and described first location-plate; Described pressurized gas system comprises first gas blow pipe that is arranged on described first location-plate the first half; The angle of described first gas blow pipe and described first location-plate the first half is smaller or equal to 90 °, and an end of described first gas blow pipe and described first " U " type guide channel are interconnected, and are connected with the Compressed Gas control device on the other end of described first gas blow pipe.
Described " U " type guider is two and is respectively first " U " type guider and second " U " type guider; Described first " U " type guider comprise transverse opening " U " type first location-plate and to first guide plate of the described first location-plate inner bending; The bottom of described first guide plate is fixedly connected with the bottom of described first location-plate; Form first " U " type guide channel of a transverse opening between described first guide plate and described first location-plate; Described pressurized gas system comprises first gas blow pipe, second gas blow pipe and Compressed Gas control device; Described first gas blow pipe be arranged on described first location-plate the first half and with the angle of described first location-plate the first half smaller or equal to 90 °; One end of described first gas blow pipe and described first " U " type guide channel are interconnected; Described second " U " type guider comprise transverse opening " U " type second location-plate and to second guide plate of the described second location-plate inner bending; Described second location-plate is arranged on the below of described first location-plate; The upper end of described second location-plate is fixedly connected with the bottom of described first location-plate; The upper end of described second guide plate is fixedly connected with the upper end of described second location-plate; Form second " U " type guide channel of a transverse opening between described second guide plate and described second location-plate, described second " U " type guide channel is not communicated with described first " U " type guide channel, described second gas blow pipe be arranged on described second location-plate the latter half and with the angle of described second location-plate the latter half smaller or equal to 90 °; One end of described second gas blow pipe and described second " U " type guide channel are interconnected, and the other end of the other end of described first gas blow pipe and described second gas blow pipe all is connected with described Compressed Gas control device.
The opening of described first location-plate and described second location-plate is towards identical.
The opening of described first location-plate and described second location-plate is towards on the contrary.
Be provided with the gap of transverse opening between described first location-plate and described second location-plate.
Compared with prior art; Advantage of the present invention is owing to comprising transverse opening " U " type guider and pressurized gas system in this device, as long as will laterally put into guider with the cloth of burr, the unlatching Compressed Gas will promote burr and carry out automatic crimping along " U " type guide channel in the guider; And do not need the processor to carry out artificial manual crimping; Crimping speed is fast, and width is even before and after the flange that rolls out, and this device is installed in the presser feet front of Sewing machines; Make cloth carry out carrying out automatic rolling through this device earlier before tangent line meets system; Improve operating efficiency greatly, and made tangent line evenly straight, guaranteed the crudy of cloth; And " U " type guider is two and when being provided with up and down; Can be simultaneously two relative crimpings of need and the cloth that is sewed together be carried out automatic rolling simultaneously; And between first location-plate and second location-plate, be provided with the gap of transverse opening; Can laterally put into the 3rd cloth at gap location as required, the 3rd cloth made between two clothes of need crimping, improve operating efficiency and crudy more.
