Abstract
The utility model relates to a closed seam sewing machine, which is composed of a bottom plate, a cantilever machine head arranged on the bottom plate, a material feeding component positioned between the bottom plate and the machine head and a power part, wherein, the machine head is provided with a machine needle and a thread lifting mechanism. The bottom plate is provided with a thread hooking mechanism and the material feeding component comprises a material pressing device and a towing plate and is driven by a compound moving mechanism. The material pressing device is provided with a rotation turning axle. Pressing feet in the material pressing device is sheathed and plugged on one end of the rotation turning axle. The other end of the rotation turning axle is driven by a rotation power device fixed on the material pressing device. The utility model solves the problem of the thread running interfere of the closed seam in sewing in order to provide a new function to an automatic sewing machine.
Description
The utility model relates to a kind of Sewing machines, relates in particular to a kind of improvement of making predetermined linear slit automatic sewing machine material pressing device, belongs to the sewing device technical field.
At present, the existing automatic sewing machine of making predetermined linear slit is formed by base plate, the cantilever head, the feeding part between base plate and head, the power section that are installed on the base plate, eedle, thread take-up mechanism wherein are housed in the head, hook line mechanism is housed in the base plate, feeding part comprises material pressing device and planker, is driven by composite-motion mechanism.During this class automatic sewing machine work, sewing is clamped between the material pressing device and planker of feeding part, intermittently send to by predetermined plane motion track with feeding part, under the mating reaction of eedle and hook line mechanism, finally can on sewing, form the linear slit of various required patterns.Yet because the material pressing device in the feeding part only has the free degree of binder direction, therefore the cabling in the time of can not dodging withdrawal of needle and whole pin weight pin can't form the sealing linear slit.
The purpose of this utility model is: at the problem of above-mentioned existing automatic sewing machine existence, a kind of blockade line seam sewing machine of cabling can dodge the heavy pin of withdrawal of needle and whole pin the time is proposed, thereby make automatic sewing machine have the stronger function of making, satisfy the requirement of making of constantly development.
In order to achieve the above object, blockade line seam sewing machine of the present utility model is made up of base plate, the cantilever head, the feeding part between base plate and head, the power section that are installed on the base plate, eedle, thread take-up mechanism wherein are housed in the head, hook line mechanism is housed in the base plate, feeding part comprises material pressing device and the planker that is driven by composite-motion mechanism, trip shaft is housed in the material pressing device, presser feet sleeve in the material pressing device is installed in an end of trip shaft, the other end of this trip shaft and the rotary power unit engagement that is fixed on the material pressing device.
During work, action of the eedle of blockade line seam sewing machine and hook line and feeding campaign all with existing automatic sewing machine roughly the same, make when the sealing linear slit of predetermined pattern is near completion, when eedle will be got back to the withdrawal of needle position with respect to the feeding campaign, the controlled driving trip shaft upset of rotary power unit, thereby get out of the way cabling, make linear slit finish sealing uninterruptedly and make.This shows that the utility model has solved the problem that cabling was interfered when the sealing linear slit was made dexterously, thereby gives automatic sewing machine new function, and it is simple and practical to set up mechanism, does not influence original function, is convenient to repacking and promotes.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment feeding part of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the partial enlarged drawing of trip shaft and presser feet among Fig. 1.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is the A-A cutaway view of Fig. 3.
The blockade line seam sewing machine that the embodiment of Fig. 1 and Fig. 2 sews up flange-like becket (a kind of centre is macropore, the uniform aperture in border, be commonly called as the ring pad, specification has the plate-like of big ring pad, little ring pad to treat stitch) and sewing for the radial sealing linear slit of a kind of usefulness.This Sewing machines comprises base plate, head, feeding part, power section, eedle, thread take-up mechanism wherein are housed in the head, the rotary shuttle hook line mechanism is housed in the base plate, feeding part comprises material pressing device 2 and planker 1, drive by composite-motion mechanism, be shaped on round table-like spigot edge below the end that is arc trip shaft 4 in the middle part of dish type presser feet 3 in the material pressing device 2 is sleeved on, this presser feet 3, periphery is shaped on the breach corresponding with the becket aperture.The other end of trip shaft 4 is inserted in the material pressing device 2, and its termination is in-line gears.Upset cylinder 5 as rotary power unit is fixed on the material pressing device 2, and wherein cylinder axis 6 anterior extension ends are a disjunctor tooth bar, the in-line gears engagement of this tooth bar and trip shaft 4 terminations, so trip shaft 4 can overturn under the driving of cylinder 5.
In addition, as shown in Figure 3-Figure 5, on presser feet 3, be fixed with bakelite tension seat 3-1, be bonded with magnet 3-2 on this tension seat 3-1.Its effect is when sewing finishes presser feet and returns initial point, and the upset by trip shaft 4 is clipped between trip shaft 4 and the tension seat 3-1 the end of a thread, and under the adhesive effect of magnet 3-2, can not get loose, thereby is that following sewing is got ready.In addition, the position at trip shaft 4 corresponding presser feet 3 breach is installed with eccentric pin 4-2 with screw 4-1.This eccentric pin structure not only can make the flange-like becket reliably locate, and can adapt to the becket of different-diameter within the specific limits by adjusting eccentric position.
When using the blockade line seam sewing machine of present embodiment, sewing is laid on the planker 1, becket pastes the bottom surface centering that is placed on presser feet 3, and circumferentially locatees under the effect of eccentric pin 4-2.After starting the machine, this blockade line seam sewing machine will be finished making of radial linear slit automatically, make becket stitch nail securely on sewing.When the sealing linear slit be near completion make, when eedle will be got back to the withdrawal of needle position with respect to the feeding campaign, upset cylinder 5 controlled driving trip shafts 4 rotate, 180 ° of the arc upsets at trip shaft 4 middle parts as a result (double dot dash line position among Fig. 4), thereby get out of the way cabling, make linear slit finish sealing uninterruptedly and make.Experiment showed, that this machine has not only solved the problem that cabling was interfered when the sealing linear slit was made dexterously, and easy to adjust, have good continuous operation and desirable adaptability.
