Abstract
The utility model discloses a scraping needle back-and-forth movement device which comprises a scraping needle back-and-forth cam, a scraping needle back-and-forth middle swing arm, a connecting rod, a scraping needle back-and-forth swing arm and a scraping needle plate base. The scraping needle back-and-forth cam is fixed on a cam shaft, one end of the scraping needle back-and-forth middle swing arm is arranged on a middle shaft in a sleeved mode, and the other end of the scraping needle back-and-forth middle swing arm moves along an outline of the scraping needle back-and-forth cam through a bearing and is connected with one end of the scraping needle back-and-forth swing arm through the connecting rod. The scraping needle back-and-forth swing arm is arranged on a swing arm shaft in a sleeved mode, and the other end of the scraping needle back-and-forth swing arm is connected with the scraping needle plate base. The scraping needle back-and-forth movement device which can enable a scraping needle plate to move towards a needle bed is provided.
Description
Technical field
The utility model belongs to technical field of knitting machinery, particularly a kind of pin device that seesaws of scraping.
Background technology
Computer flat knitting machine is when braiding, and the cloth sector-meeting that braiding is good breaks away from from knitting needle, thereby finishes braiding.And break away from the knitting needle owing to the cloth sheet that weaves has become, each coil is fitted with the cloth sheet, so when the cloth sheet that weaves need be sewed up, just must sew up by manually coil on two cloth sheets being aimed at one by one, this just makes that sewing up need of work expends great amount of manpower.So the technical staff has proposed the scheme that directly coil shifted from knitting needle, utilize and scrape needle plate and make coil knocking over from the knitting needle, and how to make scrape the needle plate proper exercise and become 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 can making to scrape needle plate and scrape the pin device that seesaws to the needle-bar motion.
For this reason, the technical solution of the utility model is: scrape the pin device that seesaws, it is characterized in that: it comprise scrape cam before and after the pin, scrape before and after the pin in the middle of swing arm, connecting rod, scrape before and after the pin swing arm and scrape pin holder; Describedly scrape that cam is fixed on the camshaft before and after the pin, described scrape before and after the pin in the middle of swing arm one end be enclosed within on the jackshaft, the other end by bearing along the contour motion of scraping cam before and after the pin, and by connecting rod with scrape pin front and back swing arm one end and be connected; Describedly scrape that swing arm is enclosed within on the arm shaft before and after the pin, the other end by bearing pin with scrape pin holder and be connected.
Further, describedly scrape that swing arm has an obtuse angle polyline shaped body before and after the pin.
Further, described have the tractive spring in the swing arm in the middle of scraping before and after the pin, makes not break away from during swing arm campaign in the middle of scraping before and after the pin to scrape pin front and back cam.
During the utility model work, the driven by motor camshaft, thus the pin front and back cam of scraping that is fixed on the camshaft is rotated thereupon.Scrape the middle swing arm in pin front and back owing to the tractive of spring, passive around scraping the cam outline motion of pin front and back, scrape the middle swing arm in pin front and back and scrape pin front and back swing arm by the connecting rod drive, make it to move around arm shaft; Scrape that the pin holder of scraping in the swing arm seesaws before and after the pin thereby make to be fixed on, make it on needle-bar before and after motion.
Description of drawings
Be described in further details below in conjunction with accompanying drawing and embodiment of the present utility model.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 scrapes the structural representation of pin front and back cam for the utility model.
The specific embodiment
Referring to accompanying drawing.Present embodiment comprise scrape cam 11 before and after the pin, scrape before and after the pin in the middle of swing arm 12, connecting rod 13, scrape before and after the pin swing arm 14 and scrape pin holder 5; Describedly scrape that cam 11 is fixed on the camshaft 1 before and after the pin, described scrape before and after the pin in the middle of swing arm 12 1 ends be enclosed within on the jackshaft 2, the other end by bearing along the contour motion of scraping cam 11 before and after the pin, and by connecting rod 13 with scrape pin front and back swing arm 14 1 ends and be connected; Describedly scrape that swing arm 14 is enclosed within on the arm shaft 3 before and after the pin, the other end by bearing pin 15 with scrape pin holder 5 and be connected.
During present embodiment work, driven by motor camshaft 1, thus the pin front and back cam 11 of scraping that is fixed on the camshaft 1 is rotated thereupon.Scrape the middle swing arm 12 in pin front and back owing to the tractive of spring, passive around scraping the cam 11 outlines motion of pin front and back, scrape the middle swing arm 12 in pin front and back and scrape pin front and back swing arm 14 by connecting rod 13 drives, make it around arm shaft 3 motions; Thereby make be fixed on scrape before and after the pin in the swing arm 14 scrape pin holder 5 on needle-bar before and after motion.
Claims (3)
1. scrape the pin device that seesaws, it is characterized in that: it comprise scrape cam before and after the pin, scrape before and after the pin in the middle of swing arm, connecting rod, scrape before and after the pin swing arm and scrape pin holder; Describedly scrape that cam is fixed on the camshaft before and after the pin, described scrape before and after the pin in the middle of swing arm one end be enclosed within on the jackshaft, the other end by bearing along the contour motion of scraping cam before and after the pin, and by connecting rod with scrape pin front and back swing arm one end and be connected; Describedly scrape that swing arm is enclosed within on the arm shaft before and after the pin, the other end by bearing pin with scrape pin holder and be connected.
