Abstract
The utility model relates to a seam splicing machine capable of feeding in the forward direction and in the reverse direction, which relates to an industrial sewing machine which mainly solves the problems that the because of the lack of a reversal feeding mechanism, the existing traditional seam splicing machine leads sewed articles to be often offline, scattered at a starting point and a termination and screws of a slot are often loose through the adjustment of needle distance. In the feeding mechanism of the utility model a cloth conveying connecting rod, a needle distance connecting rod, and a needle distance adjuster are driven by a driving shaft to move. The adjustment of the needle distance alters the screws of the groove to be the control adjustment of a knob type square tooth screw rod. A reversal feeding device is composed of a reversal feeding control shaft, a reversal feeding crank, a tension spring and a hanging frame of the tension spring, and the reversal feeding control shaft is arranged below the needle distance adjuster in the transverse direction. A rolling column which is arranged on one end of the reversal feeding crank is matched with a fork port of the needle distance adjustor, and the other end of the reversal feeding crank is connected with the reverse feeding control shaft.
Description
The utility model relates to and a kind ofly is used to embroider, the industrial sewing machine of piece, bag stalk and artistic article thereof, leather and fur products.
Existing traditional sewing machine is in operating process, owing to lack reverse feed mechanism, can not backstitch knotting at initial sum termination the end of a thread of sewing and reinforce, so sewings scatters in the frequent off-line of initial sum termination, the sewing quality of sewings can't be guaranteed; The pin code density regulating part of traditional sewing machine adopts the ditch grooved screw to fix in addition, and its contact area is little, and in the sewing process, because the vibration of this machine self makes the ditch grooved screw often loosening, pin sign indicating number regulating part is difficult to regulate.
The purpose of this utility model is on the basis of traditional sewing machine, its feed mechanism is improved, make it can finish forward and oppositely feeding, can solve the problem of reinforcing simultaneously, its sewing edge stitching can not decoherenced voluntarily in initial sum termination the end of a thread knotting of sewings; Another purpose of the present utility model is to improve the fixation problem that the pin code density is regulated, avoid since machine self to vibrate the adjusting that causes out of control.
The utility model is realized by following design.It drives work feed connecting rod (6) by driving shaft (2), needle gage connecting rod (5) and needle gage adjuster (3) move, needle gage is regulated and is controlled to adjust by needle gage adjusting knob (7), oppositely feeding is by reverse feeding Control Shaft (12), reverse feeding crank (10), extension spring (14) and extension spring suspension (13) control, its mid-cut connecting rod (5) is arranged between work feed connecting rod (6) and the needle gage adjuster, the upper contact of needle gage connecting rod (5) and work feed connecting rod (6) flexibly connect, the aperture of following contact and needle gage adjuster (3) prong (9) upper end flexibly connects, the prong (9) of needle gage adjuster (3) vertically downward, the big end in top of needle gage adjuster (3) is connected on the casing (1) with roller pin (15); Oppositely feeding Control Shaft (12) lateral arrangement is in prong (9) below of needle gage adjuster (3), oppositely there is wave washer at feeding Control Shaft (12) two ends, and be fixed on the casing (1) with screw (16), make reverse feeding Control Shaft (12) must not take place laterally to move, oppositely feeding crank (10) is positioned at prong (9) one sides of needle gage adjuster (3), the one end is connected with reverse feeding Control Shaft (12), the other end is provided with roller pin and roller (8), and be embedded in the prong (9) of needle gage adjuster (3), oppositely the middle part of feeding Control Shaft (12) is provided with extension spring suspension (13), extension spring (14) one ends are connected in extension spring suspension (13), the other end is connected in casing (1) bottom, is provided with the reverse feeding joystick of square (11) at reverse feeding Control Shaft (12) right-hand end.In addition, described needle gage adjusting knob (7), its swing arm side of being tooth screw mandrel (4), it is installed in the square tooth silk hole in casing front, and square tooth screw mandrel (4) blunt end contacts with the splayed opening curved surface (17) on needle gage adjuster (3) top.
Be the forward feeding during this machine operate as normal, when need oppositely backstitch, depress reverse feeding joystick (11), thereby drive reverse feeding Control Shaft (12), oppositely feeding crank (10) and extension spring suspension (13) rotation makes needle gage adjuster (3) rotate simultaneously, and makes the needle gage connecting rod (5) that is attached thereto, respective change takes place in work feed connecting rod (6), thereby the feeding track is become oppositely by forward.
The utility model is compared with traditional sewing machine, not only increased and oppositely backstitched function, and through the evidence forward with oppositely to make effect excellent, initial sum termination in sewing can backstitch the knotting reinforcing simultaneously, effectively prevented the off-line phenomenon of scattering, moreover needle gage regulates that to change the ditch grooved screw be knob side's tooth screw structure, solved the loosening problem of bringing because of this machine self vibration of adjustment screw.
Further structure of the present utility model is described below with accompanying drawing.Accompanying drawing 1 is the schematic perspective view of the utility model forward and reverse feed mechanism.Accompanying drawing 2 is the utility model complete machine cutaway views.Among the figure, (1) casing, (2) driving shaft, (3) needle gage adjuster, (4) square tooth screw mandrel, (5) needle gage connecting rod, (6) work feed connecting rod, (7) needle gage adjusting knob, (8) are feeding crank roller oppositely, (9) prong of needle gage adjuster, (10) are the feeding crank oppositely, and (11) are the feeding joystick oppositely, (12) reverse feeding Control Shaft, (13) extension spring suspension, (14) extension spring, (15) roller pin, (16) screw, (17) needle gage adjuster opening curved surface.
The utility model is implemented simple, and oppositely the feeding Control Shaft adopts No. 15 steel material, and length is 141mm, and oppositely feeding crank and needle gage connecting rod adopt ironcasting, and oppositely feeding crank length is 61.5mm, and the needle gage length of connecting rod is 37mm.
