Description
Affiliated technical field
The utility model relates to a kind of for making the high-speed industrial sewing machine that underwear, gloves, jeans etc. use, and particularly relates to a kind of chain-type stitch high-speed industrial sewing machine.
Technical background
Present used chain-type stitch high-speed industrial sewing machine, its all bearing all is to use sliding bearing, because being per minute 4000, changes its rotating speed, so be with an oil pump on the Sewing machines, by the lubricating oil oil circuit on the casing each sliding bearing, two pairs of bevel gears and a pair of roller gear are carried out oil jet lubrication, the oil after lubricating flows back to lubricated oil cylinder through oil return pipe again.On it the axle and lower shaft between transmission with two pairs of round metal bevel gears through a jackshaft transmission, feeding cam and tooth lifting cam are contained on the axle, link with long connecting rod crank and feed spool and feed lifting rock shaft, carry out transmission by the pair of metal roller gear between lower shaft and looper, its weak point is because of with oil spout sliding bearing and gear being lubricated, easily cause because of the seepage of the lubricating oil sewings of making dirty, cause sewings to become waste product or substandard products, because of using the metal gear transmission between the last lower shaft and between lower shaft and the curved needle shaft, link with long connecting rod crank and feed spool and feed lifting rock shaft, so noise in operating and vibration are bigger.
Summary of the invention:
The purpose of this utility model is to overcome present used chain-type stitch high-speed industrial sewing machine easily to make the bigger weak point of sewings greasy dirt, noise and vibration, and providing a kind of does not have that greasy dirt, noise are little, the little dry type of vibration does not have oily chain-type stitch high-speed industrial sewing machine.
The purpose of this utility model is achieved through the following technical solutions.Dry type does not have oily chain-type stitch high-speed industrial sewing machine by motor 9, belt 6, drive pulley 7, driven pulley 5, shaft coupling 4, last axle 2, shank parts 1, lower shaft 11, curved needle shaft 20, feed spool 22, feed lifting rock shaft 17, feeding cam 12, tooth lifting cam 14, feeding connecting rod 24, feeding crank 25, lift tooth connecting rod 15, feed lifting rock shaft crank 16, driving gear 13, driven gear 23, looper parts 19, feeding material component 21 and lift dental assembly 18 and form, motor 9 is through drive pulley 7, belt 6, driven pulley 5, one end of shaft coupling 4 and last axle 2 links, the other end and the shank parts 1 of last axle 2 link, last axle 2 passes through drive disk assembly, feeding cam 12, feeding connecting rod 24, feeding crank 25, lift tooth connecting rod 15, feed lifting rock shaft crank 16 links with an end of lower shaft 11 respectively, one end of feed spool 22 links and an end of feed lifting rock shaft 17 links, driving gear 13 is contained on the lower shaft 11, end through driven gear 23 and curved needle shaft 20 links, the other end of curved needle shaft 20 and looper parts 19 link, the other end of feed spool 22 and feeding material component 21 link, the other end of feed lifting rock shaft 17 and lift dental assembly 18 and link.The transmission that last axle 2 and lower shaft are 11 is to be with transmission synchronously, one end driven gear 23 of driving gear 13 on the lower shaft 11 and curved needle shaft 20 is nonetallic gears, feeding cam 12 and tooth lifting cam 14 all are contained on the lower shaft 11, and the bearing on its rotation position all is a rolling bearing, uses grease lubrication.
The utility model is compared with at present used chain-type stitch high-speed industrial sewing machine, the transmission that has because of 11 of last axle 2 and lower shafts changes synchronous band transmission into by two pairs of original Bevel Gear Drive, the driven gear 23 of driving gear 13 on the lower shaft 11 and curved needle shaft 20 1 ends changes nonetallic gear into by original metal gear, so noise is little during transmission, the transmission position changes rolling bearing into by original sliding bearing, and use grease lubrication, transmission changes synchronous band transmission and nonetallic gear transmission into metal gear, so need not to use again oil jet lubrication, and there is not greasy dirt, sewings is dyed by greasy dirt, because of feeding cam 12 and tooth lifting cam 14 were contained on the lower shaft 11 by being contained in originally to change on the axle 2, make feeding connecting rod 24 and lift tooth connecting rod 15 all to become short connecting rod, thereby reduce production costs, and vibration diminishes when making running by long connecting rod.
Description of drawings
Accompanying drawing 1 is a structure block diagram of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawing: 1-shank parts; The last axle of 2-; 3-active synchronization belt wheel; The 4-shaft coupling; The 5-driven pulley; The 6-belt; The 7-drive pulley; 8-is with synchronously; The 9-motor; The driven synchronous pulley of 10-; The 11-lower shaft; The 12-feeding cam; The 13-driving gear; The 14-tooth lifting cam; 15-lifts the tooth connecting rod; The 16-feed lifting rock shaft crank; The 17-feed lifting rock shaft; 18-lifts dental assembly; 19-looper parts; The 20-curved needle shaft; The 21-feeding material component; The 22-feed spool; The 23-driven gear; 24-feeding connecting rod; 25-feeding crank.During enforcement, the casing of casing of the present utility model and original chain-type stitch high-speed industrial sewing machine is the same, still use foundry goods, but dress rolling bearing place size strengthens, lubricated oil circuit on its casing is not reprocessed, can save machining period, the oil pump and the lubricated oil cylinder that save oil jet lubrication simultaneously, shank parts 1, looper parts 19, feeding material component 21, to lift dental assembly 18, motor 9, drive pulley 7, belt 6, driven pulley 5, shaft coupling 4 also the same with former chain-type stitch high-speed industrial sewing machine.The change of being done changes the transmission of last axle and following between centers into synchronous band transmission by 2 pairs of original Bevel Gear Drive, and (rotating speed of originally going up axle 2 and lower shaft 11 is identical, so the gearratio of band is 1 synchronously, be the big or small the same of active synchronization belt wheel 3 and driven synchronous pulley 10), feeding cam 12 and tooth lifting cam 14 are originally and are contained on the axle, now being retrofitted to lower shaft gets on, driving gear 13 and driven gear 23 are originally the pair of metal gear drive, now change nonetallic gear transmission (can also can use bakelite gear) into plastic gear, feeding connecting rod 24 and the length of lifting tooth connecting rod 15 are shortened, can save raw material, weight reduction, also can reduce vibration during running, sliding bearing was all used at rotation position and swing position originally, oil jet lubrication, now rotate the position and use rolling bearing instead, the swing position is still vicarious with sliding, all use grease lubrication instead, rotation position on feeding cam 12 and tooth lifting cam 14 is with (its bearing shell is contained in feeding connecting rod 24 and lifts on the tooth connecting rod 15) the needle bearing (not drawing on the figure), remaining rotary part is all used ball bearing, and its bearing shell is contained on the casing.After changing like this, shank parts 1, looper parts 19, lift dental assembly 18 and feeding material component 21 and make action in the process in running still the chain-type stitch high-speed industrial sewing machine with original is the same.
