The double needle bed warp knitting machine is suitable for knitting various fabrics, when the fabrics are knitted, piles with different lengths are required according to different requirements of the thickness of the fabrics, and the height of the piles depends on the gap between the needle backs of the front needle bed and the back needle bed, so that the pile height also depends on the distance between the front knocking-over needle groove plate and the back knocking-over needle groove plate. Therefore, the distance between the front and the rear knockover plates of the double-needle bed warp knitting machine is required to be adjusted to meet the requirements of different fabric thicknesses.

In the mechanism for adjusting the space between the knockover plates of the double-needle bed warp knitting machine in the prior art, the knockover plates are usually arranged on a swing arm which can rotate around a swing shaft, and the swing arm rotates to drive the knockover plates to rotate. When the space between the knockover plates is enlarged, the front knockover plate and the rear knockover plate rotate outwards, and the position of the knockover plate rises compared with the position before the knockover plate is not adjusted while the space between the knockover plates is enlarged. The latch needle also needs to be raised according to the cooperation of the looping machine. Because the position of the guide bar is not changed in the adjusting process, the position of the guide bar needs to be adjusted upwards correspondingly in order to ensure normal weaving. On the contrary, when the spacing between the knockover plates is reduced, the front knockover plate and the rear knockover plate rotate inwards, and the position of the knockover plate is reduced compared with the position before the knockover plate is not adjusted while the spacing between the knockover plates is reduced. The latch needle also needs to be lowered, and the position of the guide bar needs to be adjusted downwards correspondingly. Otherwise, the parts of the looping machine part are abraded and damaged, or the yarn can not be hooked, so that the knitting is influenced.

Detailed Description

The utility model is described in further detail below with reference to the figures and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The eccentric adjusting shaft of the double-needle bed warp knitting machine is realized in such a way that the requirements of different styles of cloth on the thickness of fabrics are different in the weaving process of the double-needle bed warp knitting machine, and the eccentric adjusting shaft can be realized by adjusting the space between knocking-over plates of two needle beds. In the knitting process of the double-needle bed warp knitting machine, after the fabric of the front needle bed and the back needle bed is knitted, when the drawing mechanism draws the fabric downwards towards the middle, the thickness required by the fabric is positioned by the two knockover plates of the front needle bed and the back needle bed, so that the distance between the two knockover plates of the two needle beds is enlarged, the knitted fabric is thick, the distance between the two knockover plates of the two needle beds is reduced, and the knitted fabric is thin. Therefore, the adjustment of the distance between the two knocking-over plates is very critical to the thickness of the fabric.

The straightness of the knockover plate is also very important to adjust, because the straightness of the adjustment is not straight, the woven cloth is not flat, and yarn breakage is easy to occur in the weaving process. In addition, the size of the position of the knocking-over plate and the size of the position of the looping part are consistent, so when the distance between the knocking-over plates is adjusted, the synchronization of all the looping parts is kept, and the other looping parts are not required to be adjusted when the distance between the knocking-over plates is adjusted.

The eccentric adjusting shaft provided by the utility model has the advantages that the operation of adjusting the space between the knocking-over plates is simple, the adjusting process is stable, and the accuracy is high. The knocking-over plate and other looping components move along with the swing shaft seat, so that the positions of the other looping components cannot be changed, and the quality and the yield are greatly improved. The deviation caused by readjustment of the positions of other looping parts is reduced.

Referring to fig. 1 to 7, the embodiment of the present invention includes:

as shown in figure 1, the eccentric shaft 10 of the eccentric adjusting shaft of the double needle bed warp knitting machine can drive the swing shaft seat 6 to move back and forth by slightly rotating.

Further, the eccentric adjusting shaft comprises a swing shaft 5, a swing shaft seat 6, a knockover plate 1, a needle bed swing arm 4 and a flat key 13. The swing shaft seat 6 is installed on the plane of the machine table box body 14, a key groove is milled on the plane of the machine table box body 14, a flat key 13 is installed on the key groove, the key groove is milled at the position, corresponding to the key groove of the plane of the box body 14, of the bottom of the swing shaft seat 6, and therefore it is guaranteed that the swing shaft seat 6 does stable motion along the flat key 13 of the machine table box body, and the front and back moving forward and backward can not deviate left and right.

Furthermore, an eccentric shaft 10, a swing shaft 5, a knock-over plate 1, a needle bed swing arm 4, a needle core swing arm 3 and a settlement swing arm 2 are arranged on the swing shaft seat 6. Needle bed plates are arranged on the needle bed swing arms 4, needle core beds are arranged on the needle core swing arms 3, and sinker beds are arranged on the sinker swing arms 2. Each needle bed swing arm keeps synchronous displacement when the swing shaft seat 6 advances and retreats forwards and backwards, so that the position relation of each needle bed swing arm in the adjusting process is kept unchanged, the stability is good, and the accuracy is high.

As shown in fig. 2, 6 and 7, the eccentric shaft 10 is fixed on the supporting plates 15 between the two ends of the machine and the middle of the machine, and the eccentric shaft 10 passes through the swing shaft seat 6. Dig an arc hole 61 in the middle of the pendulum axle seat 6, there are two little bosss 62 that the position is relative in the middle of the arc hole 61, and eccentric wheel 9 is installed on eccentric shaft 10, and two little bosss 62 convex parts are aimed at to eccentric wheel 9, so long as eccentric shaft 10 rotates about, two little bosss 62 are being pushed against to eccentric wheel 9 outer fringe, and pendulum axle seat 6 will follow forward and backward movement.

Further, the eccentric adjusting shafts are oppositely arranged on the front machine table and the rear machine table, the eccentric shafts 10 of the front machine table and the rear machine table can swing the eccentric shafts 10 to adjust the front and rear advance and retreat of the swing shaft seat 6 according to the thickness of the fabric, and therefore the spacing between the front and rear decoiling plates 1 is adjusted.

As shown in figure 2, the shaft end of the eccentric shaft 10 is provided with a pointer 7, a dial 8 is fixed on the wall plate, and a handle 12 is fixed on the shaft end of the eccentric shaft 10. According to the required thickness of the woven fabric, the handle 12 can be rotated clockwise or anticlockwise, so that the pointer 7 is aligned with the scale on the dial 8, and the size of the required opening interval of the front and rear knockover plates 1 is determined. The operation is simple, convenient and visual, and the accuracy is high.

As shown in fig. 3, when the machine is mounted, the starting point position of the double needle bed front and rear knockover plate 1 is set to 0, and the pointer 7 points to the scale mark '0' of the dial 8. The adjustable range of the pointer 7 is any scale of scales '0-10', and the distance between the adjustable knockover plates is any distance of 0-10 mm. As shown in fig. 4 and 5, the handle 12 is rotated clockwise to rotate the eccentric shaft 10, and the pointer 7 rotates to the scale mark '4', and the distance between the two knocking over plates is enlarged to 4 mm. If the scale is adjusted to '9', the distance between the two knocking-over plates is enlarged to 9 mm. Vice versa, the handle 12 is rotated counterclockwise, e.g. from the scale '9' back to the scale '4', at which time the distance between the two knockover plates is reduced to 4 mm.
