Description
Technical field
The invention belongs to technical field of sewing equipment, relate to a kind of Sewing machines, particularly a kind of pipe fittings fixing strap machine.
Background technology
In the parachute of military, aviation field, lifesaving appliance, usually need be with the bars of one of accessory through cloth class parcel; Bars can be solid bars or pipe fitting, the surface can be smooth, thin annular knurl or spiral grooves, and material is hard tube or flexible pipe.Above-mentioned cloth is made through manual, and not only production efficiency is low, and labour intensity is high, and the quality of product can not be guaranteed.
And outer presser feet, the interior presser feet of at present general common Sewing machines directly are connected on the head, and needle plate and work feed straightening connect and be connected on the base.Such Sewing machines can only be used for a kind of the making of pipe fitting of diameter, can't solve the making of pipe fitting of different-diameter size.So just need again the outer presser feet of design, interior presser feet, needle plate and feed dog to reach the pipe fitting that to make different-diameter.
Summary of the invention
The objective of the invention is to have above-mentioned problem to existing pipe fittings fixing strap machine, provide that a kind of production efficiency is high, sewing quality is good, can make the pipe fittings fixing strap machine of the pipe fitting of different-diameter size.
The object of the invention can be realized through following technical proposal: a kind of pipe fittings fixing strap machine; Comprise base and the head that is fixed on base top, on head, be associated with external pressure pin and interior presser feet, outer presser feet has bottom the U type that U type bottom and interior presser feet be positioned at outer presser feet; On base, be provided with needle plate and feed dog; Needle plate has the tooth of putting through hole and feed dog and is positioned at and puts the tooth through hole, and above-mentioned outer presser feet and interior presser feet are opposed up and down with needle plate and feed dog respectively, it is characterized in that; Between described outer presser feet and the head, between interior presser feet and the head, between needle plate and the base and between feed dog and the base, it is joining to have at least the first to pass through detachable mechanism; On interior presser feet and/or feed dog, has the groove that can be complementary with pipe fitting.
This pipe fittings fixing strap machine is used for tightly using fixed band fastening pipe fitting, is mainly used in aviation parachute and some lifesaving appliances.Pipe fitting and fixed band are to be placed on the needle plate, through the groove on interior presser feet and the feed dog pipe fitting are compressed, and through outer presser feet fixed band are being compressed.The diameter of the pipe fitting that this pipe fittings fixing strap machine is fixed is different; And between the outer presser feet and head of this machine, between interior presser feet and the head, between needle plate and the base and between feed dog and the base; Be joining, so just be convenient for changing different outer presser feets, interior presser feet, needle plate and feed dog and come to be complementary with pipe fitting through detachable mechanism.Outer presser feet, interior presser feet, needle plate and the feed dog of this concrete pipe fittings fixing strap machine have several, can select suitable outer presser feet, interior presser feet, needle plate and feed dog to be complementary with it by the variation of pipe fitting diameter.Certainly, between outer presser feet and the head, between interior presser feet and the head, between needle plate and the base and between feed dog and the base, some can fix some detachably also is feasible.
In above-mentioned pipe fittings fixing strap machine, be fixed with compressor arm one on the described outer presser feet, be fixed with connector one on the described head, said compressor arm bottom is an inserting slot construction, outer presser feet cooperates by screw fastening with its slot.Outer like this presser feet is connected through this structure and head, changes the outer presser feet screw that only need come loose and gets final product.
In above-mentioned pipe fittings fixing strap machine, be fixed with compressor arm two on the described interior presser feet, be fixed with connector two on the described head, said interior end of presser feet is the axis hole shape.Compressor arm was tightened with regard to available the cooperation by trip bolt with the axis hole of interior presser feet like this, was connected with head through this structure like this, and is just very convenient during presser feet in needs are changed.
In above-mentioned pipe fittings fixing strap machine, described needle plate is connected through bolt with base mutually.Needle plate is connected through bolt with base mutually, when needs are changed needle plate, just can change needle plate very easily as long as turn on bolt.
In above-mentioned pipe fittings fixing strap machine, described feed dog is connected through bolt with base mutually.When needs are changed feed dog, just can change feed dog very easily as long as turn on bolt.
Compared with prior art, this pipe fittings fixing strap machine realizes the making of the pipe fitting of different-diameter size through changing different outer presser feets, interior presser feet, needle plate and feed dog, and is simple to operate, sewing quality is high, applied range.
