Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a computerized flat knitting machine. Background Art

[0002] A computerized flat knitting machine is a double-needle bed latch needle weft knitting machine. Its cam device is like a set of planar cams. The needle feet of the knitting needles can enter the grooves of the cams. By moving the cams, the knitting needles are forced to move regularly up and down in the needle grooves of the needle bed. Through the actions of the needle hooks and needle tongues, the yarn can be knitted into a knitted fabric. During the upward movement of the knitting needles, the loops gradually exit the needle hooks, the needle tongues are opened, and the loops are hung on the needle bars after exiting the needle tongues. During the downward movement of the knitting needles, the needle hooks hook the newly laid yarn and pull it to form a loop. At the same time, the original loops are disengaged from the needle hooks, and the new loops pass through the old loops and are connected in series with the old loops. The loop strings knitted by numerous knitting needles are interconnected to form a knitted fabric. It is a widely used textile machine.

[0003] The existing computerized flat knitting machines have the following drawbacks during use: Since the flat knitting machine has a complex structure and is generally in continuous production, it is necessary to detect the previous several pieces of garment pieces during production, mainly detecting the knitting density of the clothes, etc. This process is generally carried out manually and can only be detected after the garment pieces are completely produced. If the detection result does not meet the standard, it will cause the problem of waste pieces, resulting in unnecessary waste. For this reason, we propose a computerized flat knitting machine.

Rubber pads are attached to the opposite sides of the surface of the movable plate and the surface of the pressing plate; through the single-chip microcomputer located on the surface of the flat knitting machine main body, the operation of the main cylinder and the micro cylinder can be regulated and controlled, and at the same time, the feedback signals of the laser distance sensor and the tensile overload protector can be received, so as to overall control the operation of the equipment. At the same time, the operation limits of each component can be preset. The rubber pad structure can increase the friction at the connection and improve the clamping stability.

[0008] Further, a chute is provided inside the flat knitting machine main body, and the slider is installed inside the chute; the slider is arranged inside the chute, so that the movable plate can move smoothly and play a limiting role on it.

[0009] Further, a reflector is provided on the surface of the movable plate at one end of the bottom of the flat knitting machine main body, and the reflector corresponds to the emission end of the laser distance sensor in position; the reflector structure can reflect the laser more accurately, so that the laser distance sensor obtains a more accurate feedback signal.

[0010] Further, the signal output end of the tensile overload protector is connected to the single-chip microcomputer, and the control end of the single-chip microcomputer is connected to the control ends of the main cylinder and the micro cylinder.

An movable plate and a pressing plate are provided at its discharging end. The produced garment pieces are threaded between the movable plate and the pressing plate. After the pieces start to come out, the micro cylinder controls the pressing plate to operate and cooperate with the movable plate to clamp both ends of the garment piece. Then the main cylinder operates to drive the movable plate to move to both sides respectively through the slider to stretch the garment piece. When the tensile overload protector monitors that the preset tension is reached, it stops operating to avoid damaging the garment piece. At this time, the laser distance sensor measures the distance to obtain the stretched length of the fixed-length garment piece. After calculation, the knitting density data of the garment piece can be obtained. If it is unqualified, the single-chip microcomputer can alarm through the buzzer and stop the machine in time for adjustment to avoid unnecessary waste; through the single-chip microcomputer located on the surface of the flat knitting machine main body, the operation of the main cylinder and the micro cylinder can be regulated and controlled, and at the same time, the feedback signals of the laser distance sensor and the tensile overload protector can be received, so as to overall control the operation of the equipment.
