Abstract
The utility model discloses a scraping needle up-and-down-movement device. The device comprises a scraping needle up-and-down-movement cam, a scraping needle up-and-down-movement middle swing arm, a connecting rod, a scraping needle up-and-down-movement swing arm, a scraping needle connecting rod, a scraping needle plate base and a scraping needle plate, wherein the scraping needle up-and-down-movement cam is fixed on a cam shaft; a middle shaft is sleeved with one end of the scraping needle up-and-down-movement middle swing arm, and the other end moves along the outline of the scraping needle up-and-down-movement cam through a bearing; the scraping needle connecting rod is connected with the tail end of the scraping needle plate base; and the scraping needle plate is fixed at the front end of the scraping needle plate base. According to the device, during working, the scraping needle connecting rod fixed on the scraping needle up-and-down-movement swing arm is moved, so that the scraping needle plate base with the tail end connected with the scraping needle connecting rod rotates around a pin roll, and the scraping needle plate moves up and down.
Description
Technical field
The utility model belongs to technical field of knitting machinery, particularly a kind of pin device that moves up and down of scraping.
Background technology
Computer flat knitting machine is when braiding, and woven cloth sector-meeting departs from from knitting needle, thereby completes braiding.And because the cloth sheet weaving has become on knitting needle to depart from, each coil is fitted with cloth sheet, so when the cloth sheet weaving need to be sewed up, just must be by manually coil on two cloth sheets being aimed at and is sewed up one by one, this just makes to sew up need of work and expends a large amount of manpowers.So technical staff has proposed the scheme directly coil being shifted from knitting needle, needle plate is scraped in utilization makes coil knocking over from knitting needle, and how to make to scrape needle plate proper exercise, becomes a difficult problem.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and provides a kind of and can make to scrape needle plate and scrape the pin device that moves up and down near the heel of knitting needle pin.
For this reason, the technical solution of the utility model is: scrape the pin device that moves up and down, it is characterized in that: it comprise scrape the upper and lower cam of pin, scrape pin upper and lower in the middle of swing arm, connecting rod, scrape pin pumping arm action, scrape pin connecting rod, scrape pin holder and scrape needle plate; The described upper and lower cam of pin of scraping is fixed on camshaft, described in scrape pin upper and lower in the middle of swing arm one end be enclosed within on jackshaft, the other end by bearing along the contour motion of scraping the upper and lower cam of pin; Describedly scrape pin pumping arm action and be enclosed within on arm shaft, one end by connecting rod connect scrape pin upper and lower in the middle of swing arm, the other end connects scrapes pin connecting rod; Describedly scrape pin connecting rod and scrape pin holder end and be connected; The described needle plate of scraping is fixed on and scrapes pin holder front end.
Further, described in scrape pin pumping arm action and have for " U " font body, " U " word two ends connect respectively scrapes pin upper and lower in the middle of swing arm and scrape pin connecting rod.
Further, described in scrape pin and there is tractive spring in swing arm in the middle of upper and lower, make to scrape pin and do not depart from during swing arm campaign in the middle of upper and lower and scrape the upper and lower cam of pin.
During the utility model work, driven by motor camshaft, thus the upper and lower cam of pin of scraping that makes to be fixed on camshaft rotates thereupon.Scrape the upper and lower middle swing arm of pin due to the tractive of spring, passive around scraping the upper and lower cam outline motion of pin, scraping the upper and lower middle swing arm of pin is driven and is scraped pin pumping arm action by connecting rod, make it to move around arm shaft, drive to be fixed on to scrape simultaneously and scrape pin link motion in pin pumping arm action, thereby allow end rotate around bearing pin with scraping the pin holder of scraping that pin connecting rod is connected, make to scrape needle plate and move up and down.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment of the present utility model, be described in further details.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation that the utility model is scraped the upper and lower cam of pin.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprise scrape the upper and lower cam 21 of pin, scrape pin upper and lower in the middle of swing arm 22, connecting rod 23, scrape pin pumping arm action 24, scrape pin connecting rod 25, scrape pin holder 5 and scrape needle plate 6; The described upper and lower cam 21 of pin of scraping is fixed on camshaft 1, described in scrape pin upper and lower in the middle of swing arm 22 one end be enclosed within on jackshaft 2, the other end by bearing along the contour motion of scraping the upper and lower cam 21 of pin; Describedly scrape pin pumping arm action 24 and be enclosed within on arm shaft 3, one end by connecting rod 23 connect scrape pin upper and lower in the middle of swing arm 22, the other end connects scrapes pin connecting rod 25; Describedly scrape pin connecting rod 25 and scrape pin holder 5 ends and be connected; The described needle plate 6 of scraping is fixed on and scrapes pin holder 5 front ends.
During the present embodiment work, driven by motor camshaft 1, thus the upper and lower cam 21 of pin of scraping that makes to be fixed on camshaft 1 rotates thereupon.Scrape the upper and lower middle swing arm 22 of pin due to the tractive of spring, passive around scraping the upper and lower cam 21 outline motions of pin, scraping the upper and lower middle swing arm 22 of pin is driven and is scraped pin pumping arm action 24 by connecting rod 23, make it around arm shaft 3 motions, drive is simultaneously fixed on the pin connecting rod 25 of scraping of scraping in pin pumping arm action 24 and moves, thereby allow end rotate around bearing pin 15 with scraping the pin holder 5 of scraping that pin connecting rod 25 is connected, make to scrape needle plate 6 and move up and down.
