Abstract
Disclosed is a tip end pin mechanism of a computer horizontal waving machine. The utility model is provided with a base board, two groups of lugs are disposed at the bottom of one side surface of the base board, a pivot shaft is mutually inserted into the two lugs, and the pivot shaft also inserts into an operation rod, a connecting rod and a tip end board. The operation rod is disposed between the two lugs, the connecting rod is pivoted at the top portion of the operation rod, and the tip end board is pivoted at the top portion of the connecting rod and can rectilinearly move along the surface of the base board. The both ends of the pivot shaft are respectively equipped with an operation head and a support portion with the same axle with the operation head to insert and pivot on the two lugs. An eccentric rod portion which is correspondingly inserted into the operation rod is mounted between the operation head and the support portion, the lifting of the operation rod can be realized by rotating the pivot shaft, and further the height of the tip end board which is connected with the operation rod is changed. Therefore, when the top portion of the tip end board is worn, the height of the tip end board can be adjusted by rotating the pivot shaft and then the tip end board can be continuously used, thereby the service life can be prolonged. In addition, if the tip end board does not reach the needed size in the time of processing, the tip end board can also be regulated to the demanded height, which reduces unqualified products caused by process.
Description
Technical field
The utility model relates to a kind of knitting equipment, refers to a kind of pressing foot device of computer flat-bed knitting machine especially.
Background technology
Shown in Figure 5 is the front-view schematic diagram of existing computer flat-bed knitting machine 30, it lies in the board top and is provided with a triangle needle-bar 31 that tilts forward and back, on the anteversion and retroversion inclined-plane of needle-bar 31, be respectively equipped with a needle plate 32, other is provided with a head 33 that can move back and forth along needle plate 32, be provided with programme controlled mountain plate in head 33 towards needle plate 32 these sides, with the knitting needle displacement on the programming action control needle plate 32.See also shown in needle plate 32 partial perspective views and Fig. 7 mountain plate 34 upward views of Fig. 6, this needle plate 32 be provided with a plurality of extend up and down roll ditch 320, in respectively rolling ditch 320, be respectively equipped with a knitting needle 36, each knitting needle 36 is provided with an outstanding stitch 360, is controlled displacements by the stitch 360 on these outstanding needle plate 32 surfaces by mountain plate 34.
Two groups of pilot units 35, three binding guide block 37 and two pressing foot devices 40 that lay respectively at pilot unit 35 bottoms that are positioned at two pilot units, 35 root edge sides are installed on these mountain plate 34 bottom surfaces, this pilot unit 35 comprises many guide blocks, the guide pin slot 350 (shown in the direction of arrow among the figure) that passes through with the stitch 360 that constitutes for described knitting needle 36.The pressing foot device 40 that is positioned at pilot unit 35 belows again can push the stitch 360 of knitting needle 36 according to programme-control.
This pressing foot device 40 is as shown in Figure 8, comprise a substrate 41, be fixed in eedle presser that the top board 42 at substrate 41 tops, two can lifting on substrate 41 43, two connecting rod 44 that is hubbed at eedle presser 43 bottoms respectively, two action bars 45 that are hubbed at connecting rod 44 bottoms respectively, this action bars 45 bottoms and place between two lugs 411 that are hubbed at substrate 41 bottoms with a pivot 452, wear for a torque spring 46 on two pivots 452 and respectively, make action bars 45 normalities be subjected to the up power of beat, and then make eedle presser 43 protrude in substrate 41 end faces.
The teat 451 of this action bars 45 is to be subjected to the programme-control operation, when as shown in figure 10 the teat 451 of action bars 45 being suppressed downwards, bar 44 downward beats promptly can be connected, and then it is eedle presser 43 is past drop-down, discharge this press power again, can promote knitting needle 36 so that eedle presser 43 is up passed.
Yet, because eedle presser need arrive predetermined height and can push against knitting needle, each element has its machining tolerance, may make eedle presser exceed (perhaps not reaching) predetermined altitude through the tolerance of being accumulated after the assembling, and the generation defective products, so its precision requirement that adds man-hour is high, to such an extent as to the fraction defective height increases manufacturing cost on foot.
And eedle presser unavoidable generation after using a period of time worn and torn, and can't correctly push knitting needle 36, must be changed.The braiding dealer is except essential burden eedle presser 43 element expenses; whole pressing foot device 40 need be removed when changeing; tear down operations bar 45, connecting rod 44, eedle presser 43 one by one again; after the eedle presser 43 that more renews; assembling is and rather time-consuming one by one again, and the cost that its shutdown is slowed down is also not low.
Therefore, the pressing foot device of existing computer flat-bed knitting machine has further improved necessity.
The utility model content
The utility model is difficult for making for the pressing foot device machining accuracy height that improves above-mentioned existing computer flat-bed knitting machine, and the defective that the time must be changed of wearing and tearing, therefore, main purpose of the present utility model is to provide a kind of height that can adjust eedle presser, with the pressing foot device that significantly reduces fraction defective and increase the service life.
Based on above-mentioned purpose, major technique means of the present utility model system will be placed through an operating head, the support portion that pivot two ends on action bars and the substrate lug are respectively equipped with concentric, to be placed through respectively in substrate two lugs in groups, between operating head and support portion, be provided with one section eccentric rod portion again, this eccentric rod portion axle center and support portion are eccentric shape, and this eccentric rod portion is corresponding being placed through in the action bars.
That is to say, the utility model provides a kind of pressing foot device of computer flat-bed knitting machine, system is provided with a substrate, wherein be provided with two groups of lugs in bottom, a surface in substrate, two groups of lugs place with a pivot respectively and are pivoted, and other establishes one and places and be hubbed at action bars between two lugs and for pivot, and a connecting rod is pivoted in the action bars top, this connecting rod top is pivoted one can be along the eedle presser of substrate surface slippage, wherein:
Two ends of pivot are respectively equipped with an operating head, a support portion of concentric, to be placed through respectively in substrate two lugs in groups, between operating head and support portion, be provided with one section eccentric rod portion again, this eccentric rod portion axle center and support portion are eccentric shape, and this eccentric rod portion is corresponding being placed through in the action bars.
Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:
1. be made as eccentric rod portion because pivot is placed through inner this section of action bars, when rotating hinge, get final product so that action bars is adjusted displacement, and then the eedle presser height of adjustment and action bars interlock.Thus, when wear and tear in the eedle presser top,, do not need to change eedle presser with cost saving as long as this pivot of rotation can be adjusted the height of eedle presser and continue to use.
2. because as long as rotating hinge promptly can reach the purpose of adjustment, its handled easily can significantly reduce to shut down slows down the time.
3. owing to the utility model adjustable height, therefore can compensate the tolerance of processing, therefore can amplify the margin of tolerance that adds man-hour, significantly to reduce defective products and processing cost.
