[0003] In order to better achieve different knitting effects, existing large circular knitting machines often require manual adjustment of the triangle position, which is very troublesome.

[0004] A new solution is now proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems and provide a large circular knitting machine with fully automatic triangle needle position height adjustment and a control system thereof.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: a large circular knitting machine with fully automatic triangle needle position height adjustment, comprising a machine base, a sliding ring slidably arranged on the machine base, an operating seat fixedly arranged on the sliding ring, a power part slidably arranged on the operating seat, a transmission part for adjusting the triangle needle position height is detachably installed on the power part, and a telescopic device for pushing the power part to move toward the center of the machine base is provided on the operating seat.

[0012] A control system for a circular knitting machine with fully automatic triangular needle height adjustment comprises the following steps:

[0013] The S1 basic database is established by dividing the circle into equal parts according to the triangle numbers on the same horizontal plane of the equipment. After the division is completed, the circle is numbered once, and each number is renumbered according to the triangle number in the vertical direction. Finally, an independent associated edit box is established on each renumbered data.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] like Figure 1 、 Figure 2 、 Figure 3 As shown, a large circular knitting machine with fully automatic triangle needle position height adjustment and its control system include a machine base 1, a sliding ring 2 is slidably arranged on the machine base 1, an operating seat is fixedly arranged on the sliding ring 2, a power member 5 is slidably arranged on the operating seat, a transmission member 6 for adjusting the triangle needle position height is detachably installed on the power member 5, and a telescopic device 7 for pushing the power member 5 toward the center of the machine base 1 is provided on the operating seat.

[0026] When designing this product, it was considered that the existing triangle needle position adjustment mostly relies on manual labor, which is inefficient and has a high error rate. It is often necessary to check repeatedly to confirm that the adjustment is completely correct before starting the equipment. Otherwise, arbitrary starting will cause the needle to hit. This product installs a power part 5 on the operating seat through sliding. The power part 5 adopts a servo motor. The servo motor uses precise rotation angle control to adjust the height of the triangle needle position, which can be more precise. The telescopic device 7 can be separated from the adjustment hole of the triangle needle position when the triangle needle position is not adjusted. The sliding ring 2 can be used to perform a circular motion on the machine base 1, so that the operating seat installed on the sliding ring 2 can be driven by the sliding ring 2 to reach any position of the machine base 1, thereby adjusting the height of any triangle.

[0027] The sliding ring 2 adopts a gear disc, and a motor 9 for driving the gear disc to rotate is installed on the machine base 1. The rotation of the motor 9 drives the gear disc to rotate, so that the rotation of the sliding seat 4 is more stable, and the gear disc is engaged with the gear on the motor 9, which can more perfectly realize the precise driving of the operating seat to the specified position and achieve better digital control. Here, the motor 9 adopts a servo motor.

[0028] The operating seat includes a mounting seat 3 fixedly connected to the sliding ring 2 and a sliding seat 4 sliding on the mounting seat 3. The telescope 7 and the power piece 5 are both installed on the sliding seat 4. By fixing one end of the telescope 7 to the sliding seat 4 and the other end to the power piece 5, the telescope 7 can push the power piece 5 to move when it is telescoped, thereby driving the transmission piece 6 on the power piece 5 to be accurately inserted into the triangular needle position adjustment hole. When the power piece 5 rotates, the bolt of the triangular needle position adjustment hole can be rotated to achieve the effect of adjusting the height of the triangular needle position. The telescope 7 can adopt a linear motor, a cylinder, or a screw-through stepping motor.

[0029] The mounting base 3 is provided with a power device 8 for pushing the sliding base 4 to slide in the vertical direction. Since the cam installation requires several groups to be installed in the vertical direction, and when the height of the cam needle position at different levels needs to be adjusted, the sliding base 4 can be pushed to move in the vertical direction of the mounting base 3 by the power device 8. The power device 8 can be a servo motor or a stepper motor in conjunction with a screw. The screw is rotatably connected to the mounting base 3 and is threadedly connected to the sliding base 4 at the same time. At this time, the screw can drive the sliding base 4 to move when it rotates. The power device 8 can also use a cylinder or an oil cylinder to directly push the sliding base 4 to move.

[0030] The base 1 is provided with a conductive track connected to the power supply, and the slip ring 2 is provided with a removable carbon brush, which is in contact with the conductive track for conduction. Since the slip ring 2 needs to rotate on the base 1, and various components on the slip ring 2 need to transmit power, the cooperation of the conductive track and the carbon brush can ensure that the slip ring 2 can rotate freely and unrestricted, avoiding the situation of wire entanglement.

[0031] A signal receiver is installed on the mounting base 3, and the signal receiver is electrically connected to the power piece 5, the power device 8 and the expander 7 through electrical signals. A number of signal transmitters are provided on the machine base 1, and the signal transmitter is electrically connected to the operation panel on the machine base 1, and the signal transmitter is connected to the signal receiver by radio signals. Since the machine base 1 is located in the outermost area of ​​the large circular knitting machine as a whole and has at least 3 supporting legs to ensure the stability of the machine base 1 during operation, by installing a signal transmitter on the machine base 1 and utilizing the characteristic that the connection line of the signal transmitter can completely cover the slip ring 2, a signal is sent to the mounting base 3 on the slip ring 2, so that the power piece 5, the expander 7 and the power device 8 can be moved by receiving wireless signals, and since wireless signals do not require connections, the slip ring 2 is not easily restricted when rotating.

[0032] like Figure 4 As shown, a control system for a large circular knitting machine with fully automatic triangular needle height adjustment includes the following steps:

[0033] The S1 basic database is established by dividing the circle into equal parts according to the triangle numbers on the same horizontal plane of the equipment. After the division is completed, the circle is numbered once, and each number is renumbered according to the triangle number in the vertical direction. Finally, an independent associated edit box is established on each renumbered data.

[0034] S2: Establishment of real-time database, using the primary number of the triangular position of the power member 5 as the first real-time number, the secondary number of the triangular position of the power member 5 in the vertical direction as the second real-time number, and the current rotation angle of the power member 5 as the real-time editing number;

[0035] The S3 database is associated with the device, the primary numbered data is bound to the motor 9, the secondary numbered data is bound to the power device 8, and the data in the edit box is bound to the power part 5;

[0036] S4 establishes the action logic. When obtaining new data in the input edit box, the new data is compared with the real-time data. If it is consistent with the real-time data, no action is performed. If the data is modified, the motor 9 and the power device 8 are started according to the primary and secondary numbers corresponding to the edit box, and the power member 5 is pushed to the corresponding position. After the motor 9 and the power device 8 stop, the telescopic device 7 is extended, prompting the transmission member 6 to be inserted into the corresponding adjustment hole of the triangular mounting seat 3. After the transmission member 6 completes the action, the power member 5 rotates according to the data in the edit box. After the power member 5 completes the action, the telescopic device 7 contracts. After the contraction is completed, the machine stops and waits for the next action.

[0037] The algorithm used for the action data in the primary numbering in S3 is: Xnew - Xrealtime = Xaction, when Xaction > 0, clockwise movement | Xaction | angle, when Xaction < 0, counterclockwise movement | Xaction | angle; the algorithm used for the secondary numbering data is Ynew - Yrealtime = Yaction, when Yaction > 0, upward movement | Yaction | distance, when Yaction < 0, downward movement | Yaction | distance; the algorithm used in the edit box is Znew - Zrealtime = Zaction, when Zaction < 0, counterclockwise movement | Zaction | angle, when Zaction > 0, clockwise movement | Zaction | angle.

[0038] This product controls the rotation angle of the sliding ring 2 through the primary numbering, then controls the power device 8 to adjust the height of the power part 5 through the secondary numbering, and finally controls the rotation angle of the power part 5 by changing the numbers in the editing box, allowing workers to make adjustments by directly checking the data on the adjustment sheet. The operation is simple and the checking is convenient.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0040] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
