[0024] As Figure 3 , Figure 4 , Figure 13 and Figure 14 shown, in an embodiment of the present invention, the control assembly includes: A plurality of control lines 28 are respectively arranged on one side of the plurality of first arrangement plates 11. The control lines 28 are arranged between the control line 28 board and the first snap ring 13. Subsequently, by tightening the screws that cooperate with the first mounting holes, the first snap ring 13 gradually approaches the first arrangement plate 11, and the control lines 28 are fixed between the first snap ring 13 and the first arrangement plate 11. One end of the control line 28 penetrates through the second baffle 7 and is connected to the control cabinet 2; A plurality of first negative lines 29 are respectively arranged on one side of the plurality of second arrangement plates 12.

[0027] As Figures 15 to 18 shown, in an embodiment of the present invention, it further includes: A control wire harness collecting board 36 is fixedly connected to the inner side of the second baffle 7. A first wire pressing groove 38 is formed on the control wire harness collecting board 36. A plurality of first wire passing holes 37 are spaced apart from each other at the bottom of the first wire pressing groove 38, and the plurality of first wire passing holes 37 are respectively arranged corresponding to the plurality of control lines 28.

[0028] A first wire passing pipe 39 is fixedly connected to one side of the control wire harness collecting board 36, and the first wire passing pipe 39 corresponds to the first wire passing hole 37; one end of the control line 28 sequentially penetrates through the first wire passing pipe 39, the first wire passing hole 37 and then is bent and placed inside the first wire pressing groove 38; then the ends of the plurality of control lines 28 pass through the second baffle 7 to be connected to the control cabinet 2.

[0029] A negative electrode wire harness collecting board 40 is fixedly connected to the inner side of the first baffle 6. Three second wire pressing grooves 42 are formed on the negative electrode wire harness collecting board. The three wire pressing grooves respectively correspond to the second negative electrode line 30, the control signal line 34, and the negative electrode signal line 35. A plurality of second wire passing holes 41 are spaced apart from each other at the bottom of each second wire pressing groove 42, thereby forming three rows of second wire passing holes 41, and the three rows of second wire passing holes 41 are respectively arranged corresponding to the second negative electrode line 30, the control signal line 34, and the negative electrode signal line 35.

[0030] A second wire passing pipe 43 is fixedly connected to one side of the negative electrode wire harness collecting board 40, and the second wire passing pipe 43 corresponds to the second wire passing hole 41; the second negative electrode line 30, the control signal line 34, and the negative electrode signal line 35 all sequentially pass through the corresponding second wire passing pipe 43 and the second wire passing hole 41, and then are bent and placed inside the corresponding second wire pressing groove 42; then the ends of the plurality of second negative electrode lines 30, the ends of the plurality of control signal lines 34, and the ends of the plurality of negative electrode signal lines 35 pass through the first baffle 6 to be connected to the control cabinet 2.

[0031] By designing the first wire passing pipe 39 and the second wire passing pipe 43, it is convenient to number each row of control lines 28 and the second negative electrode line 30 respectively. The above-mentioned wire collecting structure and method can ensure the compactness of the knitting machine structure, and moreover, the method is simple, the wire collecting structure is easy to disassemble and assemble, and it is convenient for the inspection and adjustment of the circuit.

[0032] Before the knitting machine knits a product, since there are multiple rows of mutually parallel second negative lines 30 and multiple columns of mutually parallel control lines 28 provided on the upper surface of the bottom plate 4, and the multiple rows of second negative lines 30 are numbered in sequence so that each row of second negative lines 30 has a specific row number, and at the same time the multiple columns of control lines 28 are also numbered so that each column of control lines 28 has a specific column number. First, each electromagnet arranged on the upper surface of the bottom plate 4 needs to be encoded according to the row number of the second negative line 30 and the column number of the control line 28. According to the knitting process of the product, the initial moving directions and moving paths of the eight spindles 3 are specified in advance, and the electromagnets that need to be controlled in sequence when the eight spindles 3 move one cycle are determined respectively, so as to ensure that the eight spindles 3 do not deviate from their respective movement trajectories during movement and there is no movement interference between the spindles 3. After determining the electromagnets that need to be controlled in sequence for the movement of each spindle 3, each spindle 3 can move in a cycle. In addition, the control signal lines 34 and the negative signal lines 35 of each row are respectively connected to the control signal output terminal and the negative terminal 16 of the control cabinet 2, and then the control cabinet 2 can issue control signals to control the energization states of the thyristors in each row.

[0033] When the knitting machine knits a product, the control cabinet 2 respectively controls the magnetic field directions of the electromagnets in sequence according to the numbers of the electromagnets corresponding to the moving paths of the eight spindles 3, and drives the eight spindles 3 to move along the planned paths respectively through the interaction with the N poles and S poles of the magnetic bodies of the eight spindles 3. At the same time, the electromagnets corresponding to each step of the movement of each spindle 3 are controlled to ensure the synchronization of the movement of the eight spindles 3 and avoid the problem of interference between the spindles 3 due to non-synchronization, which affects the working efficiency and product quality of the knitting machine.

[0034] For example, such as Figure 19 and 20As shown, when one of the spindles 3 moves, the N - pole magnet 27 below the spindle 3 is arranged at the rear end in the forward direction, and the S - pole magnet 26 is arranged at the front end in the forward direction. The electromagnets d15 - d16 corresponding to the N - pole magnetic body at the bottom of the spindle 3 in the moving path are energized to generate an N - pole magnetic field to form a repulsive force, and the electromagnets d11 - d12 corresponding to the S - pole magnetic body at the bottom of the spindle 3 in the moving path are energized to generate an N - pole magnetic field to form an adsorption force. The electromagnets d13 - d14 are not energized. Then, through the repulsive force of the electromagnets d15 - d16 on the spindle 3 and the adsorption force of the electromagnets d11 - d12 on the spindle 3, the spindle 3 can be driven to move through the cooperation of these two forces. When the spindle 3 moves to the next step, the electromagnets d13 - d14 corresponding to the N - pole magnetic body at the bottom of the spindle 3 in the moving path are energized to generate an N - pole magnetic field to form a repulsive force, and the electromagnets d9 - d10 corresponding to the S - pole magnetic body at the bottom of the spindle 3 in the moving path are energized to generate an N - pole magnetic field to form an adsorption force. At the same time, the electromagnets d15 - d16 and d11 - d12 lose power. Through the repulsive force of the electromagnets d13 - d14 on the spindle 3 and the adsorption force of the electromagnets d9 - d10 on the spindle 3, the spindle 3 can be driven to move through the cooperation of these two forces. When the spindle 3 moves again, the electromagnets d11 - d12 are energized to generate an N - pole magnetic field to form a repulsive force on the nail, and the electromagnets d7 - d8 are energized to generate an N - pole magnetic field to form an adsorption force on the nail. At the same time, the electromagnets d13 - d14 and d9 - d10 lose power. And so on, the spindle 3 will continue to move along the moving path. And so on, the top spindle 3 will continue to move along the moving path. At the same time, the electromagnets n7 - n5 on the inner - side edge and the electromagnets w8 - w6 on the outer - side edge of the moving path are energized in sequence, and generate opposite magnetisms respectively with the adsorption magnet 25 at the bottom of the spindle 3, ensuring that there is an adsorption force between the spindle 3 and the top plate 8 during the process of the spindle 3 moving from the electromagnets d15 - d16 and the electromagnets d11 - d12 to the electromagnets d13 - d14 and the electromagnets d9 - d10, and ensuring the stability of the movement. At the same time, due to the turning of the spindle 3, a control signal is sent through the control of the control cabinet 2. The control signal is transmitted to the electromagnets d15 - d16 through the control line 28 and the control connection line, and the magnitude of the current flowing through the electromagnets d15 - d16 is controlled. Since the repulsive force of the electromagnet d15 is less than the repulsive force of the electromagnet d16, and the adsorption force of the electromagnet d11 is greater than the adsorption force of the electromagnet d12, this can ensure that the spindle 33 can not only be driven to move by the electromagnets but also turn. When the spindle 3 moves in a straight line, the magnetic field intensity of the electromagnets driving the spindle 3 is the same. Therefore, the magnitude of the magnetic field of each electromagnet can be controlled through the control signal sent by the control cabinet 2, thus ensuring that the spindle 3 can turn and move in a straight line normally.

[0035] As Figure 20As shown, when the electromagnets d15 - d16 are energized, the controller in the control cabinet 2 sends an electrical signal to d15 - d16. At the same time, to ensure the smoothness of the electromagnet d15 - d16 circuit, making the electromagnets d15 - d16 generate a magnetic field, the controller issues a control signal. The control signal passes through the control signal line 34 to control the thyristors connected to the electromagnets d15 - d16 to be energized, ensuring that the first negative line 29, the second negative line 30, and the control line 28 on the electromagnet d15 - d16 circuit are in a conducting state, so that the induction coil 21 of the electromagnets d15 - d16 forms a path; when the electromagnets d15 - d16 are de - energized, the controller in the control cabinet 2 sends a zero - current signal to the thyristors connected to the electromagnets d15 - d16, making the thyristors not work, then the circuit formed by the first negative line 29, the second negative line 30, and the control line 28 connected to the electromagnets d15 - d16 is in an open - circuit state, and the induction coil 21 of d15 - d16 does not form a magnetic field. It should be noted that Figure 19 The arrow direction in Figure 20 is also the moving direction of the spindle 3 on the movement trajectory.

[0036] As Figure 20 shown, when eight spindles move simultaneously with yarn, the electromagnets n1 to n8 on the inner edge and the electromagnets w1 to w8 on the outer edge in the moving paths of each spindle 3 are controlled in the same way as the electromagnets driving the eight spindles 3 to move, and are all controlled simultaneously to ensure that during the movement of each spindle 3, it can always be adsorbed on the upper surface of the top plate 8 and will not deviate from the moving path due to its own inertia or the change of the moving direction, thus affecting the knitting quality. At the same time, the eight spindles 3 always move with the yarn, so there is always a pulling force on each spindle 3 from the yarn towards the inner side of the moving path. Therefore, the control cabinet 2 can output current signals with appropriate intensities to separately and simultaneously control the magnetic field intensities of the electromagnets on the outer edges of the moving paths of the eight spindles 3, increasing the adsorption force between the eight spindles 3 and the top plate 8 at the outer edges to offset the influence of the yarn tension on the movement stability of each spindle 3 and will not deviate from the moving paths of each spindle 3, ensuring the knitting efficiency of the knitting machine and the knitting quality of the product.

[0037] When knitting products of other specifications, the knitting machine does not need to stop to replace a new movement track, nor does it need a mechanical device for track switching. Only by switching the pre - planned moving paths of the eight spindles 3 through the controller in the control cabinet 2, the control cabinet 2 can, according to the new moving paths, sequentially and synchronously control the magnetic fields of the electromagnets corresponding to the eight spindles 3, and the knitting machine can knit new products.

[0038] A control method for a magnetic - navigation knitting machine with stepless variable track, including: S1: Number multiple electromagnets and save the electromagnet numbers in the control cabinet 2; S2: According to the numbers of the electromagnets corresponding to the movement paths of different spindles 3, the control cabinet 2 synchronously controls the energization conditions of each electromagnet in sequence. By energizing the corresponding electromagnets, attractive and repulsive forces are generated on the S - pole magnet 26 and the N - pole magnet 27 below the spindle 3 respectively, so as to drive the spindle 3 to move along the specified path for knitting work.

[0039] The present invention has the following advantages: 1. Adopting the electromagnetic - driven automatic knitting technology, it can realize the automatic track change and movement of the spindle 3 path, avoid complex mechanical transmission and track switching, and improve the knitting efficiency and automation degree; 2. Not relying on mechanical transmission, it simplifies the driving structure of the knitting machine, reduces the working noise and mechanical wear, and improves the knitting quality; 3. One knitting machine can support knitting requirements of multiple modes, multiple specifications and multiple forms; 4. Adopting the non - track running mode, it avoids the interference and jamming problems caused by the track switching mechanism, ensures the continuity and reliability of the movement, and improves the knitting quality; 5. The mechanical structure principle of the knitting machine is simple, the structure is compact, the disassembly and assembly are convenient, and the hardware maintenance and replacement of the knitting machine are convenient and fast.
