Abstract
The utility model discloses an industrial sewing machine, which is an improvement of the traditional plain joint sewing machine. The front part and the rear part of a casing are separated by an oil-shielding block. An oilless bearing is used as an operating supporter and a connecting component by a taking-up component arranged at the front part. No oil is needed for lubricating in the taking-up component, and simultaneously, the engine oil in the rear part of the sewing machine can not reach the front part. The contamination to the over-sewing material, which is caused by the leakage of the engine oil in the front part of the sewing machine, is thoroughly eliminated. The cleaning work of the oil stain on the sewing material can be canceled, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to the sewing field, particularly a kind of industrial sewing machine.
Background technology
The casing front and rear of traditional sewing machine for covering chain stitch communicates, and the mist of oil at rear portion can arrive the front portion, causes the front portion that oil is arranged, and oil goes down with shank, pollutes sewing.For setting forth conveniently, introduce the accompanying drawing of relevant traditional Sewing machines earlier.Fig. 1 is the middle joint schematic perspective view of traditional sewing machine for covering chain stitch casing.Fig. 2 is the three-dimensional combination of the take-up parts schematic diagram of traditional Sewing machines.Fig. 3 is the take-up parts perspective exploded view of traditional Sewing machines.See also accompanying drawing, in traditional Sewing machines take-up parts, last axle 31 directly contact with Upper shaft sleeve (left side) 32, relatively rotates, and last 31 is passed through needle bar crank 33 and be equipped with mutually with thread take-up tension lever 34.Paraxonic by thread take-up tension lever axle sleeve (little) 36 and line-choosing connecting rod (38) in the aperture of thread take-up tension lever 34 movingly.Pass through thread take-up tension lever axle sleeve (greatly) 37 and needle bearing 40 and thread take-up crank 41 in the macropore of thread take-up tension lever 34 movingly.The other thread take-up tension lever borehole jack 35 that is connected with of the aperture of thread take-up tension lever 34.Line-choosing connecting rod hinge axis 39 directly contacts with line-choosing connecting rod 38, relatively rotates.Pass through shank connecting rod bearing (greatly) 44 and thread take-up crank 41 in the macropore of shank connecting rod 43 movingly.Shank connecting rod bearing (greatly) 44 is connected by thread take-up crank screw 45 with thread take-up crank 41.Pass through line-choosing connecting rod axle sleeve (little) 46 and shank joint 47 in the aperture of shank connecting rod 43 movingly, shank joint 47 is furnished with shank joint screw 48, and shank joint 47 tail ends have connected shank joint slide block 42.As can be seen, in the former take-up parts, last axle 31 directly contacts with last axle axle sleeve (left side) 32, relatively rotates, and line-choosing connecting rod 38 directly contacts with line-choosing connecting rod hinge axis 39, relatively rotates.All inlay axle sleeve in two holes of thread take-up tension lever 34 and shank connecting rod 43, corresponding line-choosing connecting rod 38, thread take-up crank 41, shank joint 47 relatively rotate in their axle sleeve.These parts all need fuel feeding to lubricate, and these oil certainly will can bring suture needle along shank again, pollute.
Summary of the invention
The purpose of this utility model is to provide a kind of industrial sewing machine of eliminating the Sewing machines engine oil leakage and causing sewing is polluted.
The utility model is finished by following technical solution.This industrial sewing machine is the improvement of traditional sewing machine for covering chain stitch.Between Sewing machines casing front and rear, the retaining oil clot is housed.In the fore take-up parts, last axle is rotatably assorted with last axle bearing by last axle bearing cover.Last axle is equipped mutually with thread take-up tension lever by needle bar crank, and the paraxonic by thread take-up tension lever bearing (little) and line-choosing connecting rod in the aperture of thread take-up tension lever movingly.Pass through thread take-up tension lever bearing (greatly) and thread take-up crank in the macropore of thread take-up tension lever movingly.The hole of line-choosing connecting rod hinge axis by needle bearing and line-choosing connecting rod movingly.In the macropore of shank connecting rod by the shank connecting-rod bearing (greatly) and thread take-up crank mutually movingly.In the aperture of shank connecting rod by line-choosing connecting rod bearing (little) and shank joint mutually movingly.
The beneficial effects of the utility model are, last axle rotates in chassis hole by last axle bearing, the line-choosing connecting rod hinge axis rotates in the hole of line-choosing connecting rod by needle bearing, bearing is also all arranged in two holes of thread take-up tension lever and shank connecting rod, line-choosing connecting rod, thread take-up crank, shank joint by the bearing correspondence rotate in their hole respectively, because used oilless bearing, no longer need fuel feeding lubricated, reduced the pollution of machine oil to sewing.In addition, because the front and rear of casing is thoroughly separated with the retaining oil clot, the sewing machine oil at Sewing machines rear portion can not arrive the front portion, eliminated anterior sewing machine oil seepage and caused pollution with regard to thorough like this sewing, just can cancel the greasy dirt cleaning on the sewing, improve production efficiency greatly.

The tool present embodiment
Below in conjunction with accompanying drawing the utility model embodiment is explained.
This industrial sewing machine is the improvement of traditional Sewing machines.The joint position is fixed with retaining oil clot 21 with retaining oil clot mounting screw 22 between Sewing machines casing front and rear.In the fore take-up parts, last axle 1 is rotatably assorted with last axle bearing 3 by last axle bearing cover 2.Last axle 1 is equipped mutually with thread take-up tension lever 5 by needle bar crank 4.Paraxonic by thread take-up tension lever bearing (little) 7 and line-choosing connecting rod 9 in the aperture of thread take-up tension lever 5 movingly; Pass through thread take-up tension lever bearing (greatly) 8 and thread take-up crank 12 in thread take-up tension lever 5 and the macropore movingly.The other thread take-up tension lever borehole jack 6 that is connected with of the aperture of thread take-up tension lever 5.Line-choosing connecting rod hinge axis 11 hole by needle bearing 10 and line-choosing connecting rod 9 movingly.Pass through the shank connecting-rod bearing (greatly) 15 and thread take-up crank 12 in the macropore of shank connecting rod 14 movingly.The shank connecting-rod bearing (greatly) 15 is connected by thread take-up crank screw 16 with thread take-up crank 12.Pass through line-choosing connecting rod bearing (little) 17 and shank joint 18 in the aperture of shank connecting rod 14 movingly.Shank joint 18 is furnished with shank joint screw 19, and shank joint 18 tail ends have also connected shank joint slide block 13.
See also Fig. 7, can find out in the take-up parts of the present utility model, last axle 1 rotates in chassis hole by last axle bearing 3.Line-choosing connecting rod hinge axis 11 rotates in the hole of line-choosing connecting rod 9 by needle bearing 10.Bearing is also all arranged in two holes of thread take-up tension lever 5 and shank connecting rod 14, and by bearing, corresponding line-choosing connecting rod 9, thread take-up crank 12, shank joint 18 rotate in their hole.Because used oilless bearing to support and coupling components, no longer need fuel feeding lubricated as running.Add in the upper casing separation of joint retaining oil clot 21, eliminated because the pollution that the Sewing machines engine oil leakage of front portion causes with regard to thorough like this sewing.
