Description

Technical Field

[0001] The present invention discloses a circular knitting machine with automatic adjustment of the height of the triangular needle position and its control system, belonging to the field of textile equipment. Background Art

[0002] A circular knitting machine is a device for knitting yarn into fabric.

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

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

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

[0006] The present invention achieves the above purpose through the following technical solutions. A circular knitting machine with automatic adjustment of the height of the triangular needle position includes a machine base. A sliding ring is slidably arranged on the machine base. An operation seat is fixedly arranged on the sliding ring. A power member is slidably arranged on the operation seat. A transmission member for adjusting the height of the triangular needle position is detachably installed on the power member. An expander for pushing the power member to move towards the center of the machine base is arranged on the operation seat.

[0007] Preferably, the sliding ring adopts a toothed disc, and a motor for pushing the toothed disc to rotate is installed on the machine base.

[0008] Preferably, the operation seat includes a mounting seat fixedly connected to the sliding ring and a sliding seat slidable on the mounting seat. The expander and the power member are both installed on the sliding seat.

[0009] Preferably, a power device for pushing the sliding seat to slide in the vertical direction is arranged on the mounting seat.

[0010] Preferably, a conductive track connected to a power source is arranged on the machine base. A carbon brush is detachably arranged on the sliding ring, and the carbon brush is in contact conduction with the conductive track.

[0011] Preferably, a signal receiver is installed on the mounting seat. The signal receiver is electrically connected to the power member, the power device, and the expander through electrical signals. A plurality of signal transmitters are arranged on the machine base. The signal transmitters are electrically connected to an operation panel on the machine base. The signal transmitters and the signal receiver are connected by radio signals.

[0012] A control system of a circular knitting machine with automatic adjustment of the height of the triangular needle position includes the following steps: Establishment of the S1 basic database: Divide the angle of the circle according to the number of triangles on the same horizontal plane of the device, and perform a primary numbering after the equal division is completed. And each number is secondarily numbered according to the number of triangles in the vertical direction. Finally, establish an independently associated edit box for each data that has been secondarily numbered. Establishment of the S2 real-time database: Use the primary number of the triangular position corresponding to the power component as the first real-time number, use the secondary number of the triangular position corresponding to the power component in the vertical direction as the second real-time number, and use the current rotation angle of the power component as the real-time edit number. Association between the database and the device: Bind the data with the primary number to the electric motor, bind the data with the secondary number to the power device, and bind the data in the edit box to the power component. Establish action logic: When new data in the input edit box is obtained, compare the new data with the real-time data. If it is consistent with the real-time data, no action is taken. If the data is modified, start the electric motor and the power device according to the corresponding primary number and secondary number of the edit box, push the power component to the corresponding position. After the electric motor and the power device stop, the telescopic device extends, prompting the transmission component to insert into the corresponding adjustment hole of the triangular mounting seat. After the transmission component completes the action, the power component rotates according to the data in the edit box. After the power component completes the action, the telescopic device contracts. After the contraction is completed, stop and wait for the next action.

[0013] Preferably, the algorithm for the action data in the primary number in S3 is: X_new - X_real-time = X_action, when X_action > 0, move clockwise by |X_action| distance, when X_action < 0, move counterclockwise by |X_action| distance; the algorithm for the data in the secondary number is Y_new - Y_real-time = Y_action, when Y_action > 0, move upward by |Y_action| distance, when Y_action < 0, move downward by |Y_action| distance; Z_new - Z_real-time = Z_action, when Z_action < 0, move counterclockwise by |Z_action| distance, when Z_action > 0, move clockwise by |Z_action| distance.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The sliding ring moves in a circular motion around the working area of the machine base. At the same time, by installing a telescopic device on the operating seat, the telescopic device can push the power component to move towards the center of the circle. After the movement, the power component can insert the transmission component into the adjustment hole of the triangular clamping seat through the transmission component, and then drive the transmission component to rotate by the power component to cause the triangle to move vertically, thereby realizing the adjustment of the height of the triangular needle position, eliminating the need for manual adjustment one by one.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figure 1 、 Figure 2 、 Figure 3 shown, a circular knitting machine with automatic triangular 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 operation seat is fixedly arranged on the sliding ring 2, a power member 5 is slidably arranged on the operation seat, a transmission member 6 for adjusting the height of the triangular needle position is detachably installed on the power member 5, and an expander 7 for pushing the power member 5 to move towards the center of the machine base 1 is arranged on the operation seat.

[0019] At the beginning of the design of this product, it is considered that the existing adjustment of the triangular needle position mostly relies on manual labor, with slow efficiency and high error rate. Often, it is necessary to repeatedly check and confirm that the adjustment is completely correct before starting the equipment. Otherwise, random startup will cause the situation of needle collision. In this product, the power member 5 is slidably installed on the operation seat, and the power member 5 uses a servo motor. By using the precise rotation angle control of the servo motor to adjust the height of the triangular needle position, it can be more accurate. And through the expander 7, it can be separated from the adjustment hole of the triangular needle position when the triangular needle position is not adjusted. By using the sliding ring 2 that can move around on the machine base 1, the operation seat installed on the sliding ring 2 can reach any position of the machine base 1 driven by the sliding ring 2, realizing the adjustment of the height of any triangle.

[0020] The sliding ring 2 adopts a toothed disc. A motor 9 for driving the toothed disc to rotate is installed on the machine base 1. By rotating the motor 9, the rotation of the toothed disc is driven, so that the rotation of the sliding seat 4 is more stable. And the toothed disc meshes with the gear on the motor 9, which can more perfectly drive the operating seat to the specified position accurately, realizing better digital control. Here, the motor 9 adopts a servo motor.

[0021] 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 telescopic device 7 and the power component 5 are both installed on the sliding seat 4. By fixing one end of the telescopic device 7 to the sliding seat 4 and the other end to the power component 5, when the telescopic device 7 expands and contracts, it can push the power component 5 to move, thereby driving the transmission component 6 on the power component 5 to accurately insert into the triangular needle position adjustment hole. When the power component 5 rotates, it can cause the bolt in the triangular needle position adjustment hole to rotate, achieving the effect of adjusting the height of the triangular needle position. Among them, the telescopic device 7 can adopt a linear motor or a cylinder or a screw-through stepping motor.

[0022] A power device 8 for pushing the sliding seat 4 to slide in the vertical direction is arranged on the mounting seat 3. Since several groups need to be installed in the vertical direction for triangular installation, and when it is necessary to adjust the height of the triangular needle position at different levels, the power device 8 can be used to push the sliding seat 4 to move in the vertical direction of the mounting seat 3. The power device 8 can be a servo motor or a stepping motor cooperating with a screw. The screw is rotatably connected to the mounting seat 3 and threadedly connected to the sliding seat 4. At this time, when the screw rotates, the sliding seat 4 can be driven to move. The power device 8 can also adopt a cylinder or an oil cylinder to directly push the sliding seat 4 to move.

[0023] A conductive track connected to the power supply is arranged on the machine base 1. A carbon brush is detachably arranged on the sliding ring 2, and the carbon brush is in contact conduction with the conductive track. Since the sliding ring 2 needs to rotate on the machine base 1 and various components on the sliding ring 2 need to conduct electric power transmission, the cooperation of the conductive track and the carbon brush can ensure that the sliding ring 2 can rotate freely without restriction, avoiding the situation of wire entanglement.

[0024] A signal receiver is installed on the mounting base 3. The signal receiver is electrically connected to the power component 5, the power device 8, and the telescopic device 7 through electrical signals. A plurality of signal transmitters are arranged on the machine base 1. The signal transmitters are electrically connected to the operation panel on the machine base 1. The signal transmitters and the signal receiver are connected by radio signals. Since the machine base 1 is located in the outermost area of the whole circular knitting machine and at least three support legs are provided to ensure the stability of the machine base 1 during operation, by installing the signal transmitters on the machine base 1 and utilizing the characteristic that the connection wires of the signal transmitters can completely cover the slip ring 2, signals are sent to the mounting base 3 on the slip ring 2, so that the power component 5, the telescopic device 7, and the power device 8 can perform actions by receiving wireless signals. And since the wireless signals do not require connection wires, the slip ring 2 is not easily restricted during rotation.

[0025] As Figure 4 shown, a control system for a fully automatic circular knitting machine with automatic adjustment of the height of the triangular needle positions includes the following steps: S1 Establishment of the basic database: The angle of the circle is equally divided according to the number of triangles on the same horizontal plane of the equipment, and after the equal division is completed, it is numbered once. And each number is numbered twice according to the number of triangles in the vertical direction. Finally, an independently associated edit box is established for each data numbered twice. S2 Establishment of the real-time database: The first real-time number corresponding to the triangular position of the power component 5 is used as the first real-time number, the second real-time number corresponding to the triangular position of the power component 5 in the vertical direction is used as the second real-time number, and the current rotation angle of the power component 5 is used as the real-time edit number. S3 Association between the database and the equipment: The data with the first number is bound to the electric motor 9, the data with the second number is bound to the power device 8, and the data in the edit box is bound to the power component 5. S4 Establishment of the action logic: When new data in the input edit box is obtained, the new data is compared with the real-time data. If it is consistent with the real-time data, no action is taken. If the data is modified, according to the first number and the second number corresponding to the edit box, the electric motor 9 and the power device 8 are started, and the power component 5 is pushed to the corresponding position. After the electric motor 9 and the power device 8 stop, the telescopic device 7 extends, prompting the transmission part 6 to insert into the corresponding adjustment hole of the triangular mounting base 3. After the action of the transmission part 6 is completed, the power component 5 rotates according to the data in the edit box. After the action of the power component 5 is completed, the telescopic device 7 contracts. After the contraction is completed, the machine stops and waits for the next action.

[0026] The algorithm for the motion data in the first - level numbering in S3 is: X_new - X_real - time = X_motion. When X_motion > 0, it moves clockwise by |X_motion| distance; when X_motion < 0, it moves counter - clockwise by |X_motion| distance. The algorithm for the data in the second - level numbering is Y_new - Y_real - time = Y_motion. When Y_motion > 0, it moves upward by |Y_motion| distance; when Y_motion < 0, it moves downward by |Y_motion| distance. The algorithm for the numbers in the edit box is Z_new - Z_real - time = Z_motion. When Z_motion < 0, it moves counter - clockwise by |Z_motion| distance; when Z_motion > 0, it moves clockwise by |Z_motion| distance.

[0027] This product controls the rotation angle of the sliding ring 2 through the first - level numbering, then controls the power device 8 to adjust the height of the power component 5 through the second - level numbering, and finally controls the rotation angle of the power component 5 by changing the numbers in the edit box. Thus, workers can adjust by directly checking the data on the adjustment form, with simple operation and convenient checking.
