Description

Sewing machine for bed cushion

The utility model relates to a kind of mattress Sewing machines, especially for the special-purpose mattress Sewing machines of making the mattress core courage with straw.

Known to the designer, also do not have this type of mattress Sewing machines now and come out.Fashionable in recent years in the wire spring core courage mattress of generation, because of elastic fatigue produces the soft or hard immoderation, introduce waist and ache, with the old man more so, and price is higher.Thereby people thirst for having and a kind ofly can overcome the not enough and cheap of wire spring mattress, pleasant bedding cool in summer and warm in winter.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned mattress, designs and manufactures a kind ofly can satisfy people and crave for and solve and unsolved this technical barrier is exclusively used in and makes the mattress Sewing machines of making the core courage with straw.

This product is realized as follows with novel purpose: adopt the gear drive of hand lever pressurization ratchet control speed, the operation principle that eedles bob zip is made straw mattress core courage, designed walking mechanism has been installed on frame, on walking mechanism, install hold-down mechanism and vertical needling mechanism, and horizontal needling mechanism, on the vertical needling mechanism wire frame and drum are housed, laterally are connected in by eedles and zip hook on the needling mechanism and form mattress core courage Sewing machines on the walking mechanism.

The utility model can be realized horizontal inserting needle 40mm, several 34 pins of synchronous working pin, and vertically needle gage is adjustable arbitrarily, maximum sewing thickness 110mm, can make mattress core courage full-size is 2200 * 1450 * 110(mm), and per tour eight hours three people operate simultaneously, can produce 50 in mattress core courage.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is that the utility model master looks sketch.

Fig. 2 is the utility model diagrammatic side views.

Among the figure: latch 25 plate washers 26 pressing plates 27 vertical needle on 1 famous brand 2 guide rails, 3 frame 4 tooth bars, 5 bearing 6 depression bars, 7 ratchet 8 hold-down mechanisms, 9 lathe lighting lamps and lamp bracket 10 walking mechanisms 11 vertical needling mechanism 12 ratchet handles 13 vertical turnover pin handle 14 wire frames (in-built drum) 15 trolley frames 16 handwheels 17 steel wire bed surfaces 18 eedles 19 guide rods 20 drag hook set levers 21 eccentric handle 22 poles 23 horizontal inserting needle handgrip 24 stopping wheels

With reference to Fig. 1, Fig. 2. the fastening basis that frame 3 is helped lathe by the angle steel welding.Adopt gear and tooth bar to cooperate, on frame 3 one sides affixed upper rail 2, on guide rail 2 fixing upper rack 4; The only affixed guide rail 2 of opposite side is installed walking mechanism 10 on them.Walking mechanism 10 by trolley frame 15 and on ratchet 7, ratchet handle 12, pinion, 5 groups of faces of bearing.With axle be fixed on the trolley frame 15 pinion and four bearings 5 respectively with 2 one-tenth on tooth bar 4 and guide rail movingly, walking mechanism 10 can be rolled flexibly along guide rail 2.On walking mechanism 10, be equipped with by depression bar 6, pressing plate 26, plate washer 25, handwheel 16 and on latch 24, the hold-down mechanism 8 that eccentric handle 21 connects to form.Pressing plate 26 has axis hole, is connected in frame 3 both sides with having four of step, and an end is fixed on the trolley frame 15, and other end cross-under is on plate washer 25, all with being threaded.Pass on the axis of the plate washer 25 that has axis hole and be equipped with one section tooth bar, the axis lower end is in " ⊥ " shape is socketed in the slotted eye that pressing plate 26 offers in advance.Tooth bar on the axis matches with handwheel 16 on being fixed on plate washer 25, and handwheel 16 is provided with latch 24.Have the supported hole of support guide rod 19 on one end of pressing plate 26, guide rod 19 is provided with horizontal inserting needle handgrip 23, the other end of guide rod 19 pass through axle supported hole projecting shaft outer and with eedles 18, pole 22 connects, one end of pole 22 is fixed on the guide rod 19 with nut, the other end is locked the axle head that handgrip 20 is fixed on the same side frame 3 by steel wire with drag hook, and eedles 18 on the end pin joint of pole 22 usefulness sleeves catcher can move it with guide rod 19.Has zip line hook on eedles 18 syringe needles.The vertical needle 27 that below the trolley frame 15 of walking mechanism 10, is installed in gear, tooth bar and links to each other with tooth bar, vertical needling mechanism 11 that vertical inserting needle handle 13 is formed and the wire frame 14 that is fixed on the tooth bar lower end.Walking mechanism 10 can realize vertical inserting needle, drive hold-down mechanism 8 simultaneously, vertical needling mechanism 11 and by eedles 18, guide rod 19, the horizontal needling mechanism that pole 22 and horizontal inserting needle handgrip 23 are formed moves together, and it moves is to be added on ratchet on the ratchet handle 13, ratchet is rotated, by big or small meshed transmission gear, pinion is fixed on the tooth bar 4 on the frame 3, realizes moving.

Before the operation, with wire frame 14 interior lines travelling expenses foot sewing threads, the sewing the end of a thread on every drum is led to the end of a thread that wire clamp penetrates in corresponding vertical needle 27 holes and stops certain-length earlier, put on the sewing thread on the eedles 18; Head of a bed depression bar 6 is opened, be ready to sufficient fresh, clean, do not have go mouldy, do not have rot, dry, the straw that cleans.

During operation, shift walking mechanism 10 onto tail, hold down gag 8 is raised to suitable height and firm with latch 24 locks.On request with the straw lay to the steel wire bed surface 17 of Sewing machines.Depression bar 6 with head is pushed down straw, and depresses drag hook set lever 20 and eccentric handle 21 with depression bar 6 lock jails.With ratchet handle 12 walking mechanism 10 is moved on to sewing position, depress vertical inserting needle handle 13, make vertical needle 27 penetrate the straw mattress certain altitude smoothly, a slow astern distance again forms a bigger coil with sewing thread and is advisable and keeps motionless.Unclamp eedles drag hook set lever 20 and eccentric handle 21, spur horizontal inserting needle handgrip 23, make eedles 18 pass the coil of each vertical needle point smoothly, utilize eedles 18 syringe needle line hooks that the end of a thread is tied a knot.The pass-out eedles withdraws from vertical needle, has so just finished the sewing of a line.Shake the ratchet handle 12 of walking mechanism 10 vertical needle gage is transferred to desired location, just can carry out the sewing of another line, as with repeatedly until finishing whole sewing works by above-mentioned steps operation.Latch on the stopping wheel 16 24 is extracted, rotated handwheel 16 and make the gear drive tooth bar, rise hold-down mechanism 8 backs and pin, unclamp inclined to one side handle 21 and drag hook locking handgrip 20 and can unclamp depression bar 6, remove the mattress core courage of having made then with latch 24.

The utility model hold-down mechanism 8 can produce 300-500kg pressure, and the line-spacing 20-50mm of walking mechanism 10 inserting needles moves back apart from 20-50mm.

Also can adopt Motor Drive walking mechanism and hold-down mechanism, and vertical, horizontal inserting needle, realize the work of making mattress straw mattress core courage.
