Description

The woven bag Sewing machines

The utility model relates to a kind of Sewing machines, particularly a kind ofly makes the woven bag Sewing machines that woven bag, paper bag are used specially.

It is platform-type producing at present both at home and abroad the workbench of making the woven bag Sewing machines (head) that woven bag, paper bag use, and main shaft is in the basifacial casing of workbench.When it is installed on the sewing machine table, work top raised platen face, needing the additional wood cover of outfit to be used as working plate could use.The lubricated needs of this kind Sewing machines are manually to each kinematic pair, oilhole place filling lubricating oil.

It is flat that the purpose of this utility model provides a kind of workbench of making the woven bag Sewing machines (head) that woven bag, paper bag use, and its work top and bedplate surface are substantially at grade; Newly-designed thorn material lead wires mechanism, string-hooking mechanism, thread take-up mechanism and feed mechanism compact conformation; Crawler belt presser feet in the new design feed mechanism can adapt to woven bag, the paper bag of making easy sliding material bound edge; Be provided with auto-oiled lubricating system in the machine, guarantee machine be in the running, all the time have sufficient lubricated.

The purpose of this utility model is achieved in that the workbench of woven bag Sewing machines (head) is flat, be installed in the frame hole of platen, work top and bedplate surface substantially at grade, woven bag Sewing machines (head) is installed on the cabinet parts by newly-designed thorn material lead wires mechanism, string-hooking mechanism, thread take-up mechanism, feed mechanism and oil pump feed lubricating system etc. and food tray is formed.Main shaft is located in the casing on work top top, main shaft drives thorn material lead wires mechanism, string-hooking mechanism, thread take-up mechanism with feed mechanism and presser feet (series) (presser feet (series) comprises that oneself has the presser feet and the newly-designed crawler belt presser feet of technology) thereof, carry out sewing work.Food tray is installed in the middle and lower part, frame hole of platen, the food tray pad of chassis base bottom surface and food tray coincide, oil pump is installed in the bottom of chassis base, the oil pump bottom is immersed in the oil sump of food tray, the oil-out place of oil pump receives the branch food tray on casing top with oil pipe, form auto-oiled lubricating system by minute food tray with oilhole, oil pipe, wick etc., lubricating oil is diverted in the position of each kinematic pair, the full machine self-oiling that circulates by minute food tray.

Because the work top of employing said structure, Sewing machines and bedplate surface are substantially at grade; Main shaft is located in the casing on work top top, in order to reduce the distance of main shaft to work top, in thorn material lead wires mechanism innovative design crank throw formula shank connecting axle, making the alignment of shafts is the 165mm that 225mm is reduced to the design to the distance of bottom of shell by the traditional design size, reduce 60mm, also helped other each mechanism's minification; In string-hooking mechanism, adopted " a kind of string-hooking mechanism of use in sewing machine " (applying for a patent separately) to make looper collude the lineman and made travel speed and accelerate, minimizing by a relatively large margin needle bar stroke; (contrast the woven bag sewing machine needle bar stroke 57mm that oneself has technology, the needle bar stroke 45mm of this machine design.) presser feet (series) in the feed mechanism: oneself has the presser feet of technology to make the woven bag of general requirement, paper bag; Can change newly-designed crawler belt presser feet if make woven bag, the paper bag of easy sliding material bound edge, the crawler belt presser feet in the process of sewing, to make upper strata and the sewing of lower floor of woven bag, the paper bag of easy sliding material bound edge reach feeding consistent, the function of feed sewing machine about being equivalent to; Auto-oiled lubricating system has replaced the artificial frequent maintenance of refueling, and particularly hand oiling has the oiling impropriety unavoidably, and machine weares and teares when lacking the state of lubricating oil easily, and automatic oiling has overcome these shortcomings.

Below in conjunction with drawings and Examples the utility model is further specified.
