Description

Letter-gram cam device of computerized flat knitting machine

Technical Field

The utility model relates to a letter gram triangle device of computerized flat knitting machine.

Background

The sinker of the computerized flat knitting machine is arranged between two knitting needles and is controlled by a sinker cam, so that the sinker swings back and forth to press the fabric.

A prior art letter-gram cam is shown in fig. 4, and includes an upper limit wall 212, a lower limit wall 214, a butt groove 213 formed by the upper limit wall and the lower limit wall, and a guide wheel installed on the back of the letter-gram cam. When the sinker works, the butt of the sinker is matched in the butt groove, the push-pull driving mechanism on the back of the letter gram mother board drives the letter gram triangle to vertically move on the letter gram mother board, and therefore the sinker is driven to swing back and forth through the matching of the butt groove and the butt. In the prior art, in order to realize effective transition of a butt from a butt groove to an adjacent butt groove, both the left and right ends of the upper limit wall and the lower limit wall are set as slope sections. However, since the sinker cams move vertically and there is a gap between two adjacent sinker cams, that is, there is a gap between the butt grooves, during the process of transferring the butt of the sinker from the butt groove of one sinker cam to the butt groove of the adjacent sinker cam, there is a long uncontrolled suspension process, that is, the suspension time is about 20 seconds, which affects the textile quality and causes the sinker cam not to control knitting needles below 12 needles.

Detailed Description

The driving mechanism of the present invention is further described with reference to fig. 1 to 3.

A letter gram triangle device of a computerized flat knitting machine comprises a letter gram mother board 1,

letter gram triangles

21 and 22 and a driving mechanism 5, and is characterized in that:

the letter gram mother board 1 is provided with two groups of guide groove groups 3, each group of guide groove group 3 comprises a first guide groove 31 and a second guide groove 32, the upper end of the first guide groove 31 and the upper end of the second guide groove 32 extend in an inclined mode, and the inclined angle is 40-60 degrees.

The first guide groove 31 and the second guide groove 32 are respectively fitted with one

letter cam

21, 22, the

letter cams

21, 22 are located on the front surface of the letter master 1, and the back surface of each letter cam has a guide wheel which is fitted in the first guide groove 31 or the second guide groove 32.

The driving mechanism 5 is a driving plate and is positioned on the back of the letter gram mother board 1, the top surface of the driving plate is a driving surface 4 for supporting the guide wheels, and the driving surface 4 is matched with the guide groove group 3 to drive the

letter gram triangles

21 and 22 to move obliquely.

When in use, the guide wheels of the letter-

gram triangles

21 and 22 are simultaneously matched in the driving surface 4 and the first guide groove 31 and the second guide groove 32, and the driving plate is provided with a rack and is connected with a corresponding driving motor through the rack so as to drive the driving plate to move relative to the letter-gram mother plate 1; when the driving plate moves relative to the letter parent plate 1, the driving surface 4 supports the guide wheels at different heights to drive the guide wheels to move along the extending direction of the first guide groove 31 or the second guide groove 32, namely, to drive the

letter triangles

21 and 22 to move obliquely, so that the letter triangles 21 move obliquely towards the inclined surface sections 211 of the adjacent letter triangles 22 to be right above the inclined surface sections 221 of the adjacent letter triangles 22, and therefore, the sinker can fall onto the inclined surface sections 221 located below quickly after slipping out of the inclined surface sections 211 above, the uncontrolled time of the sinker is reduced remarkably, namely, the uncontrolled time can be reduced to 10 seconds or below, the stability of the

letter triangles

21 and 22 for sinker control is improved remarkably, and knitting needles below 12 needles are controlled.

The embodiment is further configured as follows: the inclination angle of the first guide groove 31 and the second guide groove 32 is 50 degrees. The 50 degree angle is an optimum inclination angle to facilitate the sliding of the guide wheel in the first guide groove 31 or the second guide groove 32 and to optimize the distance between the two adjacent butt grooves 213.

The embodiment is further configured as follows: the driving surface 4 comprises a horizontal section 42 and a first inclined section 41 and a second inclined section 43 which are arranged at two ends of the horizontal section 42, wherein the first inclined section 41 and the second inclined section 43 extend oppositely. The first inclined section 41 cooperates with the first guide groove 31 to move the letter cam 21 in a diagonal direction in cooperation with the first guide groove 31. After the guide wheel slides to the first inclined section 41 from the horizontal section 42, the supporting point of the first inclined section 41 to the guide wheel gradually rises, so that the guide wheel and the corresponding letter triangle 21 move upwards, and simultaneously, under the guiding action of the first guide groove 31, the guide wheel can slide along the extending direction of the first guide groove 31, so that the letter triangle 21 obliquely moves, otherwise, the letter triangle 21 is driven to obliquely move downwards.

The embodiment is further configured as follows: the sinker cam is provided with an upper limit wall 212, a lower limit wall 214 and a sheet butt groove 213 formed by the upper limit wall 212 and the lower limit wall 214; the length of the upper limiting wall is smaller than that of the lower limiting wall, and an upper notch 215 is formed at one end of each butt groove 213 facing the adjacent butt groove 213. This upper notch 215 can reach the effect of dodging for on the inclined plane section drives the piece butt when upwards moving to one side, can not bump to last limiting wall 212, improve safety and stability to the sinker control.

The embodiment is further configured as follows: the driving mechanism 5 is provided with a limiting groove 51. The limiting groove 51 can limit the moving range of the driving plate relative to the letter gram mother plate, and the problem that the driving plate is separated from the guide wheel due to excessive moving relative to the letter gram mother plate is avoided.
