Winder machine barrel ingot device
The utility model is a kind of device that is used for the bobbin winder doff.
Before the utility model was made, the tube ingot device of homemade 1332 type bobbin winders was made up of spindle, hand-to-arm grip frame and spindle support.Spindle is installed on the hand-to-arm grip frame and can swings, so that lay paper tube or take off bobbin, the hand-to-arm grip frame is connected with spindle support, and spindle support and retainer plate are installed on the central shaft of bobbin winder, between spindle support and the retainer plate sliding bearing are housed.Spindle is made up of spindle blade, rolling bearing, flyer, the head of ingot, pressure bowl, steel ball, rubber ring, and the pressure bowl withstands six steel balls that are arranged in the flyer groove under the effect of spring, and steel ball holds out against the rubber ring in the groove; The head of ingot is fixedlyed connected with flyer; Spindle blade is terminal to be inserted in the installing hole of ingot tail, in the ingot tail thimble is housed, and thimble is used for promoting the pressure bowl of flyer and does axially-movable, thereby the fine motion up and down of the steel ball on the pressure bowl changes the pressure to rubber ring; The ingot tail is connected with the hand-to-arm grip frame with pin, and the ingot tail can be 50 ° swing as angle, and ingot tail lower end is provided with locating slot, realizes the location by the alignment pin that is installed on the hand-to-arm grip frame.Adopt above-mentioned tube ingot device following defective often to occur in the doff process: circular runout and axial float take place in the head of ingot easily in high speed rotary, influence tube forming; The locating slot of ingot tail lower end weares and teares easily, and thimble and pressure bowl be wearing and tearing easily also, for some contact, influence the effect of pressure bowl between steel ball and the rubber ring, make rubber ring can't stablize paper tube securely, cause tube forming bad, generation chrysanthemum core or spider web phenomenon.
Except that the tube ingot device of above-mentioned homemade bobbin winder, Japan originates from the spindle that moves bobbin winder and is made up of spindle blade, radial ball bearing, flyer, the head of ingot, rubber ring, gland, spring, thimble.Two radial ball bearings are housed between spindle blade and the flyer, spring, gland and rubber ring are installed in the outside of flyer, rubber ring is by gland and spring compression distortion, produce tensile force and be used to hold paper tube, the inner chamber of the big end of flyer is provided with four through holes, can lay four thimbles, be used for withstanding gland and spring, the big end of the flyer outside is provided with transmits the protruding circle that rotates.This spindle is rational in infrastructure, and rubber ring can firmly be held paper tube, and the tube forming quality is good, but can't directly apply to homemade bobbin winder.
The purpose of this utility model provides a kind of improved tube ingot device, and the spindle that Japan is originated from moving bobbin winder is transformed, and is installed on the hand-to-arm grip frame of homemade bobbin winder.Use the forming quality that this ingot device can guarantee bobbin, improve the following machine qualification rate of bobbin.
The tube ingot device that the utility model proposes is made up of spindle, hand-to-arm grip frame and spindle support, the spindle of being made up of spindle blade, radial ball bearing, flyer, the head of ingot, thimble, gland, spring, rubber ring is installed on the hand-to-arm grip frame, the hand-to-arm grip frame is connected with spindle support, spindle support and retainer plate are installed on the central shaft of bobbin winder, the head of ingot that it is characterized in that the truncated cone of spindle along the circumferential direction is provided with the rubber ringlet is housed in the groove groove, leave lead on the head of ingot after the external screw thread, leave pilot hole before the flyer small end internal thread, adopt movingly between lead and the pilot hole.Through so improving, improved the axiality of the head of ingot, the head of ingot and paper tube are fitted in turning course well.In addition, the spindle blade tail end of spindle passes the endoporus and the groove that is fixed in the jacking block of hand-to-arm grip frame that the angle of wedge is 20 ° an inclined-plane briquetting, be connected with the hand-to-arm grip frame with the ingot pin, in the inner chamber of the big end of flyer ring washer is housed, little spring is installed between ring washer and the inclined-plane briquetting, the inclined-plane briquetting abuts against on the jacking block under the effect of spring, and the end of spindle blade is provided with locating slot, realizes the location by positioning pressuring plate; Flat thrust ball bearing is housed between spindle support and the retainer plate.Through so improving, eliminated the end play of spindle and spindle support, make the spindle revolution steadily, the spindle support landing is flexible, has guaranteed the forming quality of bobbin.
Following concrete enforcement to this ingot device is further described with reference to accompanying drawing, and accompanying drawing is the structure chart of this ingot device.This ingot device mainly is made up of spindle, hand-to-arm grip frame (12) and spindle support (15), and spindle is installed on the hand-to-arm grip frame (12), and hand-to-arm grip frame (12) is connected with spindle support (15), and spindle support (15) is installed on the central shaft of bobbin winder with retainer plate (17).Spindle is made up of spindle blade (2), radial ball bearing (3), flyer (4), the head of ingot (1), rubber ring (7), gland (6), spring (5), thimble (8), between spindle blade (2) and the flyer (4) two radial ball bearings (3) are housed, use case off between two bearings (3), spindle blade (2) little-end bearing (3) is fixed with nut, and spindle blade (2) big-end bearing (3) abuts against on the boss of flyer (4) inner chamber; Spring (5), gland (6) and rubber ring (7) are installed in the outside of flyer (4), and spring (5) is by the shaft-use elastic gear ring location, and spring (5) compresses gland (6), and gland (6) compresses the rubber ring (7) that leans against on the boss of flyer (4) outside again; Flyer (4) is held greatly on the boss of inner chamber and is along the circumferential direction evenly laid four through holes, can lay four thimbles (8) and be used for withstanding gland (6) and spring (5); Flyer (4) small end and the head of ingot (1) are with being threaded, the head of ingot (1) leaves lead after going up external screw thread, leave pilot hole before flyer (4) the small end internal thread, adopt between lead and the pilot hole (referring to partial enlarged drawing A in the accompanying drawing) movingly, the head of ingot of truncated cone (1) along the circumferential direction is provided with groove, rubber ringlet (19) is housed in the groove, the spindle blade of spindle (2) tail end passes the endoporus and the groove that is fixed in the jacking block (11) of hand-to-arm grip frame (12) that the angle of wedge is 20 ° an inclined-plane briquetting (10), be connected with hand-to-arm grip frame (12) with ingot pin (13), in the inner chamber of the big end of flyer (4) ring washer is housed, be used for withstanding four thimbles (8), little spring (9) is installed between ring washer and the inclined-plane briquetting (10), inclined-plane briquetting (10) is abutting against under the effect of little spring (9) on the jacking block (11), the end of spindle blade (2) is provided with locating slot, realizes the location by positioning pressuring plate (14); Flat pushing away is housed between spindle support (15) and the retainer plate (17) is ball bearing (16), retainer plate (17) is fixed on the central shaft of bobbin winder with holding screw (18).
