Abstract
The utility model relates to a needle selecting device for a knitting round jacquard loom. A supporting body is arranged on a supporting frame. An adjustable supporting body is fixed on the back end of the flat plate of a needle selecting sheet. The front end of the flat plate of the needle selecting sheet is rotationally connected with a yoke end which is arranged in a limited supporting body. Electrostriction material is attached to the flat plate of the needle selecting sheet and the front end of the yoke end is connected with a guiding component made of wear-resistant polymer material. The utility model has high response speed and stable movement without generating jump when the front end of the needle selecting sheet presses the needle pushing sheet, and therefore, the knitting leakage of flowers can never occur.
Description
The utility model relates to the device that weft-knitting machine is used, and is specifically related to knitted jacquard circular knitting machine needle selecting device.
The braiding of the decorative pattern of knitted jacquard circular knitting machine is to be closed, separate with the extension of rise cam by the swing of needle jack, promotes knitting needle and moves up and down and realize; And the swing of needle jack is to be achieved by the rotation of the motion that is installed on the selection piece on the needle selecting device in conjunction with syringe.The homemade knitted jacquard circular knitting machine of present domestic extensive use, its needle selecting device mainly is made of cylinder that pattern bit is housed and selection piece.
Along with the variation that people require the fabric style, the knitted jacquard fabric that needs the large-scale decorative pattern of tool emerges, and this just requires the knitted jacquard circular knitting machine can knit out large-scale decorative pattern.And to reach this requirement, the response speed of circular knitting machine needle selecting device must realize high speed, could knit out large-scale decorative pattern under the situation that does not increase selection piece and pattern bit number.If increase the number of selection piece and pattern bit, the needle selecting device volume is increased, cause the installing space generation problem of needle selecting device.
For the response speed that improves needle selecting device and the operating frequency of selection piece, abroad the someone has proposed a kind of technical scheme of piezoelectric type needle selecting device.Publication number is that the Chinese patent application of CN1042576A discloses this technical scheme, and name is called knitting needle driving mechanism of kintting machine.This device utilizes the charged deformation of piezoelectric element to drive the selection piece bending, needle jack and rise cam is hung close, throw off, and selects the promotion knitting needle to move up and down and realizes the decorative pattern braiding.Because the response speed of piezoelectricity original paper is fast, when applying high frequency electric pulse, needle selection speed is improved, thereby, in the quantity that does not increase selection piece and pattern bit, do not increase under the situation of knitting machine size, knit out large-scale decorative pattern.But, the deficiency that this needle selecting device exists is, when being applied to it on the knitted jacquard circular knitting machine, because selection piece is in the state that freely swings basically, when selection piece is pressed into needle jack and carries out needle selection, needle jack very easily makes selection piece produce to the component that reaction force produced of selection piece and jumps, and the alternating movement instability that causes the extension of needle jack and rise cam to close or throw off makes the decorative pattern braiding occur leaking and spends.Next is, this needle selecting device selection piece flat board middle part easily produces prestrain and can not be in complete free state after clamping, add the fragility of piezoelectric ceramics original paper, makes the service life of selection piece can not be permanent.Besides, in order to alleviate the wearing and tearing of selection piece and needle jack pin heel contact site, abroad add once heat treated metal guide part at similar needle selecting device selection piece head, can reduce the replacing number of times of selection piece, but weak point has been to increase the load of selection piece, and has therefore reduced the response speed of selection piece, and the wearing and tearing of needle jack are increased, need often to change needle jack, strengthened noise in addition.
The purpose of this utility model is to provide a kind of response speed fast, the knitted jacquard circular knitting machine needle selecting device of long service life.
The utility model knitted jacquard circular knitting machine has a support with needle selecting device, support is provided with adjustable support body and spacing supporting mass, yoke end is installed on spacing supporting mass rotationally, flat board is connected with yoke end rotationally, be pasted with electrostriction material on the flat board, this flat back and adjustable support sports association connect, and the yoke end leading section is associated with wear-resisting guide member.
The device mode of said yoke end on spacing supporting mass is to make that the yoke end end is unidirectional departs from the device mode that poised state swings up and down.
The wear-resisting guide member that said yoke end leading section is joined is the macromolecular material guide body.
The utility model knitted jacquard circular knitting machine can be when increasing substantially needle selection braiding speed with needle selecting device, owing to adopt spacing supporting mass to come the supporting thill pike pole, yoke end is limited to around the rotation of fulcrum unidirectionally to be departed from and resets, and define the maximum deviation distance, so, can not produce up and down when the needle jack pin is called in person the guide member of the dull and stereotyped front end of pressured selection piece and jump, the alternating movement of the extension of needle jack and rise cam is closed, throwing off is stable, the colored phenomenon of knitting leakage can not occur; Again owing to be attached at electrostriction material on the selection piece flat board its antifatigue and bear load-bearing capacity and obviously be better than in the past piezoelectric element when under avoiding the frequency of resonance region, working, so can prolong the service life of selection piece; Here, selection piece is meant the flat board that attaches electrostriction material, the single piece that yoke end constitutes; Because the selection piece flat back is fixed in the adjustable support body, can make flat board be in free state fully again, eliminate the prestrain that clamping flat board in middle part is produced, therefore help prolonging the service life of electrostriction material; Also owing to be associated with wear-resisting macromolecular material guide member, thereby can alleviate the wearing and tearing between selection piece and the needle jack, prolong the service life of selection piece and needle jack, alleviate the operating noise of knitting machine simultaneously at the dull and stereotyped leading section of selection piece.
