Abstract
The invention discloses a positioning roller device for rake feeding, which comprises a roller, a bearing, a central shaft and a split washer, wherein the roller adopts a cylindrical structure, a circle of boss is arranged in the middle of the circumference of the roller, and inclined surfaces are arranged on the left side and the right side of the boss; a cylindrical inner hole is formed in one side of the roller; the bearing is placed in the inner hole of the roller, and the outer ring of the bearing is in interference fit with the inner hole of the roller; one end of the central shaft penetrates through the roller and the bearing and is tightly matched with the bearing, and the split washer is mounted at an end opening; the central shaft is matched with the bearing, and the other end of the central shaft is fixed on a round rake feeding and retracting rod. According to the invention, a plurality of positioning roller devices for rake feeding are mounted side by side at equal intervals on the round rake feeding and retracting rod on the same height through central shafts so as to form a track structure to facilitate feeding of a needle rake.
Description
Technical field
The invention belongs to technical field of knitting machinery, particularly enter rake positioning roller device.
Background technology
At present, in existing sewing machine, having a kind of is straight line stitching instrument machine, pin rake with garment piece directly can be put on sewing machine and sew up, saved in circular stapler machine, spend by two cloth sheet coil alignment and be set to manpower and the time on dials, and be not easy to occur the problems such as coil dislocation.And straight line stitching instrument facility have one to enter to harrow track, pin rake can be entered smoothly, rapidly and sew up workspace.
Summary of the invention
Object of the present invention provides a kind of can enter to harrow on track to pin rake location, and facilitate that pin rake enters enter to harrow positioning roller device.
For this reason, technical scheme of the present invention is: enter to harrow positioning roller device, it is characterized in that: it comprises roller, bearing, central shaft and split washer; Described roller is column structure, has a circle boss, the Bian Wei inclined-plane, the left and right sides of boss in the middle of the circumference of roller; Described roller one side has columniform endoporus; Described bearing is placed in the endoporus of roller, the endoporus interference fit of the outer ring of bearing and roller; Described central shaft one end, through roller and bearing, with bearing close-fitting, is provided with split washer on port; Described central shaft and bearing match, and the other end of central shaft is fixed on circular turnover rake rod.
It is upper that the present invention is arranged on circular turnover rake rod by central shaft, sustained height interval same distance side by side several, form track structure so that the entering of pin rake.In the present invention, the platform of the right and left of roller boss is for the location of pin rake below, and the inclined-plane, left and right of middle boss, for the location, left and right of pin rake; When bearing makes pin rake on roller with the rolling friction of pin rake, thereby make pin harrow the brisk suturing mechanism that passes in and out easily.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiments of the present invention, be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A cutaway view of the present invention.
Fig. 3 is work schematic diagram of the present invention.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprises roller 1, bearing 2, central shaft 3 and split washer 4; Described roller 1 is column structure, has a circle boss 11, the Bian Wei inclined-plane, the left and right sides of boss 11 in the middle of the circumference of roller 1; Described roller 1 one sides have columniform endoporus; Described bearing 2 is placed in the endoporus of roller 1, the endoporus interference fit of the outer ring of bearing 2 and roller 1; Described central shaft 3 one end, through roller 1 and bearing 2, with bearing 2 close-fittings, are provided with split washer 4 on port; The other end of described central shaft 3 is fixed on circular turnover rake rod 5.
