Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a roller adjustment device for a 16-needle computerized flat knitting machine. Background Art

[0002] Computerized flat knitting machine is a double needle plate latch needle weft knitting loom. Its cam device is like a set of flat cams. The needle feet can enter the groove of the cam, move the cam, and force the needle to move up and down regularly in the needle groove of the needle plate. Through the action of the needle hook and the needle latch, the yarn can be woven into knitted fabrics.

[0003] During the product weaving process of the currently used 16G computer flat knitting machine (i.e. 16-needle computer flat knitting machine), the adjustment range of the distance between the main roller and the auxiliary roller inside the existing computer flat knitting machine is limited. The adjustable distance between the main roller and the auxiliary roller can be used for normal weaving of fabrics without lace, but when weaving fabrics with flower needles, even if the distance between the main roller and the auxiliary roller is adjusted to the maximum, since the distance between the main roller and the auxiliary roller is still relatively narrow for fabrics with flower needles, the pulling force of the main roller and the auxiliary roller on the fabric can easily tear the fabric to form waste pieces, which can only be discarded and need to be re-woven.

[0004] Therefore, the pulling force of the main roller and the auxiliary roller of the existing 16-needle computer flat knitting machine is less coordinated with the knitting of fabrics with flower needles, which may reduce the knitting quality of the fabric, resulting in poor practicality of the computer flat knitting machine for knitting cashmere sweaters and other raw materials, and also reduces the knitting efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a 16-needle computer flat knitting machine roller adjustment device to solve the problem that the spacing between the main roller and the auxiliary roller of the existing 16-needle computer flat knitting machine is difficult to meet the needs of fabrics with flower needles when knitting cashmere sweaters, the pulling force and the fabric matching degree are low, which easily reduces the quality of the knitted fabric and even forms waste pieces, resulting in poor practicality of the computer flat knitting machine for knitting cashmere sweaters and low knitting efficiency.

[0006] In order to achieve the above-mentioned purpose, the basic scheme provided by the utility model is: a 16-needle computer flat knitting machine roller adjustment device, including a machine body, a main roller, an auxiliary roller and a connecting assembly, the machine body is fixedly connected to two bearing seats, both ends of the main roller are connected to the bearing seats, connecting shafts are connected to both sides of the machine body, and the two ends of the auxiliary roller are respectively connected to the two connecting shafts with belts, a spring is provided on one side of the auxiliary roller, and the spring is connected to the machine body and the auxiliary roller through the connecting assembly, and an adjustment assembly for adjusting the distance between the main roller and the auxiliary roller is provided in the machine body.

[0007] The principle and beneficial effect of the utility model are as follows: the utility model uses a spring to pull the auxiliary roller so that it has a tendency to approach the main roller, and uses an adjustment component to control the distance between the auxiliary roller and the main roller. When the distance between the auxiliary roller and the main roller is increased, thicker fabrics can be woven, and when the distance between the auxiliary roller and the main roller is decreased, thinner fabrics can be woven, so that the distance between the main roller and the auxiliary roller can just meet the thickness requirement of the fabric, avoiding the situation where the thread is broken and the edge is damaged due to excessive pulling during the pulling of the main roller and the auxiliary roller when the stitches are reduced during the weaving process, thereby improving the fabric quality and efficiency.

[0008] Solution 2, which is a preferred basic solution, the adjusting assembly includes an adjusting block, a push rod and an adjusting rod, one end of the adjusting rod rotates and penetrates the machine body, the other end of the adjusting rod is fixedly connected with a screw, the free end of the screw is threadedly connected to the adjusting block, the inner wall of the machine body is connected with a limit block, the limit block limits the adjusting block and prevents the adjusting block from falling off, the side of the adjusting block away from the adjusting rod is hinged to the push rod, the free end of the push rod is provided with a mounting groove, the machine body is connected with a hinge shaft, the hinge shaft is rotatably connected in the mounting groove, the push rod is connected with a convex portion, the convex portion is against the secondary roller, and the side of the push rod close to the limit block is rounded;

[0009] When the adjusting rod is rotated forward, the screw is gradually screwed out of the adjusting block, the adjusting block moves toward the limit block, the push rod is deflected in the counterclockwise direction, and the push rod lifts the auxiliary roller to the side away from the main roller; when the adjusting rod is rotated backward, the screw is gradually screwed into the adjusting block, the adjusting block moves toward the adjusting rod, the push rod is deflected in the clockwise direction, and the auxiliary roller gradually approaches the main roller under the tension of the spring and the support of the push rod;

[0010] By rounding the end of the push rod, it is easier to increase the adjustment angle of the push rod than to set the end of the push rod to a right angle. If the end of the push rod is set to a right angle, the right-angled end will abut against the limit plate, so that the push rod can no longer rotate when it abuts the limit plate; that is, when the push rod rotates, it will not first abut the limit rod, and the adjustment block can also completely contact the limit block. Setting the rounded corners allows the push rod to rotate freely without being restricted by distance when the adjustment block moves.

[0011] Solution 3, which is the preferred basic solution, the connecting assembly includes a first hook and a second hook, the end of the auxiliary roller is connected to a pulling block, the first hook is fixedly connected to the pulling block, the second hook flange is connected to the body near the side of the adjusting rod, and the two ends of the spring are respectively hooked on the first hook and the second hook;

[0012] The auxiliary roller is pulled toward and close to the main roller by the first hook and the second hook hanging spring. At the same time, because the auxiliary roller is against the top rod, the auxiliary roller has a tendency to move toward the main roller, so as to better perform the weaving operation.

[0013] Option 4 is a preferred option of Option 3, wherein the spring is a tension spring; the tension spring is used to give tension to the secondary roller, thereby pulling the secondary roller toward the main roller and allowing the end of the secondary roller to rest against the top rod.

[0014] Option 5 is a preferred option of Option 2, wherein the fillet angle is 100° to 140°. A suitable fillet angle is set so that the push rod can rotate freely on the adjustment block and have enough space to be hinged with the adjustment block.

[0015] Option six is ​​a preferred option of option five, in which one end of the adjusting rod outside the body is connected to a knob; by providing the knob, it is convenient for the operator to turn the adjusting rod. BRIEF DESCRIPTION OF THE DRAWINGS
