Description

A Bar Laying Mechanism of Large Gauge Double Needle Bed Warp Knitting Machine

technical field

The utility model relates to a bar-laying mechanism of a large-gauge double-needle bed warp knitting machine, which belongs to the technical field of warp knitting machines.

Background technique

The spacer fabric produced by the double-needle bed warp knitting machine has the characteristics of lightness, breathability, comfort, and cushioning protection. It has been used on a large scale in the fields of shoe upper fabrics, back cushions and seat cushions; The swing between the knitting needles of the needle bed is the main movement of the double-needle bed warp knitting machine for laying yarn into loops. The traditional bar movement is to rely on the swing shaft of the bar to drive the bar bed to swing to complete the yarn laying. For the double-needle bed warp knitting machine Its defect is that the relative displacement of the swing of the bar is limited. When the spacer fabric gauge (the distance between the front and rear needle beds) exceeds 50mm, the existing bar mechanism is difficult to realize the swing of this large displacement, which cannot meet the needs of the market for large-gauge fabrics. needs and cannot keep up with the new situation of development. Because the adjustment of the displacement needs to be done by adjusting the mechanical device, the dwell time of the bar is fixed during one cycle of the main shaft. The traditional warp knitting machine bar laying mechanism includes a bar bed, a bar hanger, a connecting rod, a bar swing arm, and a bar swing shaft. The crankshaft or cam mechanism drives the connecting rod to move up and down, and the bar swing arm fixed on the bar swing shaft drives the bar bed to swing back and forth. For the double-needle bed warp knitting machine, the displacement caused by the swing of the bar is limited (maximum 50mm), and the adjustment of the movement displacement needs to be completed by adjusting the mechanical device. The dwell time of the bar bed is fixed during one cycle of the main shaft. Therefore, the traditional bar swing mechanism has a complex structure and limited displacement, and cannot complete the weaving of large-gauge (ie greater than 50mm) interval fabrics.

Contents of the invention

In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is: to provide a large-gauge double-needle bed warp knitting machine bar laying mechanism to solve the problem of double-needle bed warp knitting machine large-gauge interval fabric combing mechanism. To solve the problem of lapping yarn, realize the lapping movement of fabrics with large gauge (greater than 50mm) on double-needle bed warp knitting machines.

In order to solve its technical problems, the technical solution adopted by the utility model is: calculate the displacement and the position and pause time that the comb bed needs to move according to the size of the spacer fabric gauge and the needs of the process, and calculate the displacement , Pause position and pause time parameters are input into the host computer, and the host computer controls the servo motor to drive the comb bed to move to complete the yarn laying. The maximum displacement that the bar bed can move (the maximum thickness of the spacer fabric that can be woven) is determined by the length of the ball screw, which can realize the weaving of spacer fabrics with a large gauge (greater than 50mm);

The designed bar laying mechanism of large-gauge double-needle bed warp knitting machine includes bar bed, bracket, base, ball wire, ball screw, motor seat, servo motor and linear guide rail. Its characteristics are: all The comb bed is installed on the bracket, the bracket is installed on the base, the ball screw is installed in the middle of the base and connected with the base, the servo motor is installed at the end of the ball screw through the motor base; the servo motor is connected with the host computer, And controlled by the upper computer, the servo motor controls the base to move forward and backward and pause, and also controls the forward and backward movement and pause of the bar bed, so as to complete the yarn laying movement of the bar bed between the front needle bed and the rear needle bed ;

2. The movement and pause of the comb bed are performed by servo motors, the displacement, pause time and position are adjustable, and the movement is precise, which can realize the lapping motion of fabrics with different intervals, especially fabrics with large intervals;

3. The base is installed on the slider of the linear guide rail, and the linear guide rail is used to make the movement of the comb bed more smooth, stable and reliable.

Compared with the prior art, the utility model has the following characteristics and progress: due to structural limitations, the traditional bar laying device can only realize the weaving of spacer fabrics within 50 mm, and the utility model solves the problem of combing spacer fabrics of more than 50 mm. The problem of bar laying yarn; the maximum displacement of the bar moving in this utility model can reach 150mm (the specific displacement length depends on the length of the ball screw), which can easily realize the laying movement of large-gauge fabrics, the size of the moving displacement of the bar and the pause time It can be set in the upper computer through the computer.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Referring to accompanying drawings 1 and 2, the designed bar-laying mechanism of a large-gauge double-needle bed warp knitting machine consists of a bar bed 1, a front needle bed 6, a rear needle bed 7, a ball screw 8, and a motor base 9. Servo motor 10, base 11, linear guide rail 12, slider 13, bearing seat 14, upper computer 15 and bracket 16. Their connection relationship is: there are two linear guide rails on the warp knitting machine head and tail wall panels 12. There is a base 11 connected between the two linear guide rails through a slider 13, and a ball screw 8 is connected to the base. One end of the ball screw 8 is fixed on the bearing seat 14, and the other end is connected to the servo through the motor base 9. The motor 10 is connected, and the servo motor is also connected with the upper computer 15; three brackets 16 are fixed on the bottom surface of the base 11, and each bracket 16 is equipped with a corresponding number of bar guide seats according to the style of the woven fabric, and each bar bed 1 passes through the guide The seat is installed on the support 16, and the bottom of the bar bed 1 is equipped with a front needle bed 6 and a rear needle bed 7 with a distance D. When knitting on a double-needle bed warp knitting machine, the bar bed 1 should form a loop sequentially on the front needle bed 6 and the rear needle bed 7. When the loop forming cycle starts, the latch needle in the front needle bed 6 will rise, and the motor 10 will rotate forward at this time. The ball screw 8 drives the base 11 to move forward. When the base 11 moves to the front of the latch needles of the front needle bed 6 with the knitting bar bed, the motor 10 reverses and drives the base 11 to move backward. All knitting bar beds move to the back of the latch needles of the front needle bed 6, the latch needles in the front needle bed 6 descend, and the front needle bed 6 completes the knitting motion. At this time, the latch needles in the rear needle bed 7 rise, and when the base 11 moves to the front of the latch needles of the rear needle bed 7 with all the looped bar beds, the motor 10 rotates forward to drive the base 11 to move forward. When all the looping bar beds move to the back of the latch needles of the rear needle bed 7, the latch needles in the rear needle bed 7 descend, and the rear needle bed 7 completes the looping movement, and the cycle repeats.
