[0057] At present, the sewing template machines in the garment industry need to sew more and more process templates, and also have higher requirements on their sewing efficiency.

[0058] However, current sewing template machines basically use screws and linear guides to drive the frame module. If the frame module is too heavy, it is easy to cause a large static friction in the sewing template machine, resulting in insufficient driving force of the drive motor during operation, resulting in uneven stitch length of sewing garments, small stitch length at the start of sewing and large stitch length at the stop, etc., which not only affects sewing efficiency, but also has poor sewing effects.

[0059] Based on this, the present application embodiment proposes a material frame support device, please refer to Figure 1 and Figure 2 The material frame support device may include a first magnetic member 10, a platen support 20, a first coil assembly 31, a second coil assembly 32 and a material frame support 40;

[0060] The first coil assembly 31 and the second coil assembly 32 are both connected to the controller, the top of the table bracket 20 is connected to the table 1 of the sewing template machine; the top of the material frame bracket 40 is connected to the material frame module 2 of the sewing template machine, and the material frame bracket 40 is provided with a first magnetic member 10, and the first coil assembly 31 and the second coil assembly 32 are respectively distributed on opposite sides of the first magnetic member 10;

[0061] The first coil assembly 31 and the second coil assembly 32 work together with the first magnetic member 10 based on the working current provided by the controller to move the material frame bracket 40 in the vertical direction to adjust the suspension height of the material frame module 2 relative to the platform 1 .

[0062] It should be noted that the first magnetic member 10 can be a permanent magnet or other magnetic device that can work together with the coil to generate magnetic force (such as soft ferrite, magnetic alloy, silicon steel sheet, etc.), and this embodiment does not specifically limit this. The first coil assembly 31 and the second coil assembly 32 can directly drive the material frame bracket 40 to move in the vertical direction when working with the first magnetic member 10 based on the working current provided by the controller to make the material frame bracket 40 move in the vertical direction; or drive the material frame bracket 40 to move in an oblique direction, so that the material frame bracket 40 generates a displacement component in the vertical direction, thereby realizing the position change of the material frame bracket 40 in the vertical direction.

[0063] In addition, it should be noted that the first coil assembly 31 and the second coil assembly 32 both include at least one coil. In order to enable the bottom of the material frame bracket 40 to float above the table bracket 20, that is, to ensure that there is a gap between the material frame module 2 and the table 1, the first coil assembly 31 and the second coil assembly 32 need to generate two magnetic fields with opposite magnetic properties based on the working current provided by the controller, and the inductance of the first coil assembly 31 and the second coil assembly 32 need to be the same and the current direction needs to be opposite, so as to work together with the first magnetic component 10 to generate a vertically upward magnetic force (that is, opposite to the direction of gravity).

[0064] On this basis, in a feasible implementation manner, the first coil assembly 31 and the second coil assembly 32 may both be composed of a coil in the form of an "8" (ie, an 8-shaped coil).

[0065] Among them, when the 8-shaped coil is energized, its current direction can be referred to Figure 3 ,Depend on Figure 3 It can be seen that when the 8-shaped coil is energized, the current can form a counterclockwise current Ia and a clockwise current Ib.

[0066] If the 8-shaped coils of the first coil assembly 31 are distributed at the S level of the first magnetic member 10, and the 8-shaped coils of the second coil assembly 32 are distributed at the N level of the first magnetic member 10, then Figure 3 The current direction of the 8-shaped coil of the first coil assembly 31 is shown. Figure 4 The 8-shaped coil of the first coil component 31 can form two magnetic fields with N-level magnetism on the upper side and S-level magnetism on the lower side at the S-level of the first magnetic component 10; the 8-shaped coil of the second coil component 32 can form two magnetic fields with S-level magnetism on the upper side and N-level magnetism on the lower side at the N-level of the first magnetic component 10.

[0067] If the 8-shaped coils of the first coil assembly 31 are distributed at the N-level of the first magnetic member 10, and the 8-shaped coils of the second coil assembly 32 are distributed at the S-level of the first magnetic member 10, then Figure 3The current direction of the 8-shaped coil of the second coil assembly 32 is shown. Figure 5 The 8-shaped coil of the first coil component 31 can form two magnetic fields at the N level of the first magnetic part 10, with the upper magnetic field being the S level and the lower magnetic field being the N level; the 8-shaped coil of the second coil component 32 can form two magnetic fields at the S level of the first magnetic part 10, with the upper magnetic field being the N level and the lower magnetic field being the S level.

[0068] In another feasible implementation, the first coil assembly 31 and the second coil assembly 32 may both be composed of two spiral coils. When the two spiral coils are energized, the current directions of the two spiral coils are opposite, so that the magnetism of the magnetic fields formed by the two spiral coils is also opposite.

[0069] The present embodiment provides a material frame supporting device, which includes a first magnetic part 10, a first coil assembly 31, a second coil assembly 32, a table bracket 20 and a material frame bracket 40; the first coil assembly 31 and the second coil assembly 32 are both connected to the controller, the top of the table bracket 20 is connected to the table 1 of the sewing template machine, the top of the material frame bracket 40 is connected to the material frame module 2 of the sewing template machine, the material frame bracket 40 is provided with a first magnetic part 10, and the first coil assembly 31 and the second coil assembly 32 are respectively distributed on the opposite sides of the first magnetic part 10; wherein, the first coil assembly 31 and the second coil assembly 32 act together with the first magnetic part 10 based on the working current provided by the controller, so that the material frame bracket 40 moves in the vertical direction to adjust the suspension height of the material frame module 2 relative to the table 1.

[0070] Therefore, in this embodiment, the first magnetic member 10, the first coil assembly 31 and the second coil assembly 32 are arranged between the table support 20 connected to the table 1 of the sewing template machine and the material frame support 40 connected to the material frame module 2 of the sewing template machine, so as to provide working current to the first coil assembly 31 and the second coil assembly 32 through the controller, so as to utilize the first magnetic member 10, the first coil assembly 31 and the second coil assembly 32 to jointly generate magnetic force, so that the material frame support 40 moves in the vertical direction, so that the bottom of the material frame support 40 will no longer contact the table support 20, but will be suspended above the table support 20. Thus, it is ensured that when the screw rod and the linear guide rail are used to drive the material frame module 2 to run, there can be a gap between the material frame module 2 and the table 1, thereby reducing the static friction between the material frame module 2 and the table 1 in the sewing template machine, improving the technical defects of the sewing template machine due to the large static friction during the sewing process, and improving the sewing efficiency and sewing effect of the sewing template machine.

[0071] Based on the above first embodiment, a second embodiment of the material frame support device of the present application is proposed. In the second embodiment, the material frame support device may further include a second magnetic member 50 and a Hall sensor 60;

[0072] The crossbeam mounting hole of the material frame bracket 40 is embedded with a bracket crossbeam 41, and the crossbeam mounting hole is located between the top of the material frame bracket and the first magnetic member 10; the bracket crossbeam 41 is provided with a limiting groove that matches the shape of the second magnetic member 50, and the second magnetic member is embedded in the bracket crossbeam 41 through the limiting groove;

[0073] The Hall sensor 60 is installed on the sensor installation position of the material frame bracket 40 , and the sensor installation position is located in the area of ​​the material frame bracket 40 that is acted upon by the second magnetic member 50 ; the Hall sensor 60 is used to feedback the suspension height of the material frame bracket 40 under the action of the second magnetic member 50 .

[0074] It should be noted that the second magnetic member 40 may be a bar magnet, a ring magnet or other magnetic device that enables the Hall sensor to calculate the height according to the magnetic field change at its position, etc., and this embodiment does not specifically limit this. The area in the material frame bracket 40 that is acted upon by the second magnetic member 50 refers to the magnetic field coverage of the second magnetic member 50 on the material frame bracket 40, and the sensor installation position may be set at any position within the magnetic field coverage.

[0075] In this embodiment, the second magnetic member 50 and the Hall sensor 60 are provided to feedback the suspension height of the material frame bracket 40. Therefore, the feedback suspension height of the material frame bracket 40 can be used to provide working current to the first coil assembly 31 and the second coil assembly 32 to avoid the situation where the material frame module 2 cannot be suspended due to insufficient working current, and avoid the situation where the gap between the material frame module 2 and the table 1 is too large due to excessive working current, which affects the sewing effect.

[0076] Based on the above second embodiment, a third embodiment of the material frame support device of the present application is proposed. In the third embodiment, the material frame support device may further include a gravity sensor, which is arranged on the material frame module 2 to feedback the gravity of the material frame module 2.

[0077] In this embodiment, a gravity sensor is provided to feedback the gravity of the material frame module 2. Therefore, the gravity of the material frame module 2 fed back by the gravity sensor and the suspension height of the material frame bracket 40 fed back by the Hall sensor 60 can be used to provide working current to the first coil assembly 31 and the second coil assembly 32, so as to further avoid the situation that the material frame module 2 cannot be suspended due to insufficient working current, and further avoid the situation that the gap between the material frame module 2 and the table 1 is too large due to excessive working current, which affects the sewing effect.

[0078] In addition, the embodiment of the present application further provides a sewing template machine, which may include the material frame support device in the above embodiment. It is understandable that, since the above material frame support device is used in the sewing template machine, the embodiment of the sewing template machine includes all technical solutions of all embodiments of the above material frame support device, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0079] In one possible implementation, please refer to Figure 6 and Figure 7 , the sewing template machine may include a table 1, a material frame module 2, a module bracket 3, a guide rail 4, a slider 5, a motor 6, and a screw rod 7;

[0080] The bottom of the table 1 is connected to the top of the table bracket 20 in the material frame support device, and the two connection positions at the bottom of the material frame module 2 are respectively connected to the tops of the two material frame brackets 40 in the material frame support device in a one-to-one correspondence;

[0081] The module bracket 3 includes a movable part and two connecting parts. The movable part is located between the two connecting parts. The screw hole of the movable part is inserted with a screw 7. The tops of the two connecting parts are connected to the table bracket 20, and the bottoms of the connecting parts are connected to the top of the slider 5.

[0082] The screw rod 7 is connected to the motor 6, and the slider 5 is slidably arranged in the guide rail 4;

[0083] The motor 6 is used to drive the lead screw 7 to pull the slider 5 connected to the module bracket 3 to slide in the guide rail 4, so as to drive the material frame module 2 to run horizontally on the table 1.

[0084] It can be understood that, in the process of driving the slider 5 connected to the screw rod 7 traction module bracket 3 to slide in the guide rail 4 by the motor 6 to drive the material frame module 2 to move horizontally on the table 1, the material frame bracket 40 used to support the material frame module 2 will move in the vertical direction under the joint action of the first magnetic member 10, the first coil assembly 31 and the second coil assembly 32 in the material frame support device, so as to be suspended above the table bracket 20. As a result, a gap will be left between the material frame module 2 and the table 1, thereby reducing the static friction between the material frame module 2 and the table 1 in the sewing template machine, improving the technical defects of the sewing template machine due to the large static friction during the sewing process, and improving the sewing efficiency and sewing effect of the sewing template machine.

[0085] Further, in a feasible implementation, the material frame module 2 may include a material frame fixing module 21, a material frame cylinder 22 and a material frame 23;

[0086] The material frame cylinder 22 is installed on one side of the material frame fixing module 21. The material frame 23 is pressed down by the material frame cylinder 22 to be fixed together with the material frame fixing module 21. The two connecting positions at the bottom of the material frame fixing module 21 are respectively connected to the tops of the two material frame brackets 40 in a one-to-one correspondence.

[0087] It should be noted that the material frame 23 is pressed down by the material frame cylinder 22 and fixed together with the material frame fixing module 21 , so that the material frame 23 can move horizontally on the table 1 with the help of the material frame fixing module 21 .

[0088] In addition, the present application also provides a material frame suspension support control method, please refer to Figure 8 The material frame suspension support control method may include step S10:

[0089] Step S10, receiving a start signal of the sewing template machine, providing a working current to the coil assembly in the material frame support device, so as to control the coil assembly to form a target magnetic force together with the first magnetic member in the material frame support device under the action of the working current;

[0090] The target magnetic force is used to move the material frame bracket in the material frame supporting device in the vertical direction to adjust the suspension height of the material frame module in the sewing template machine relative to the table in the sewing template machine.

[0091] It should be noted that in order to achieve the purpose of moving the material frame bracket in the material frame support device in the vertical direction so as to adjust the suspension height of the material frame module in the sewing template machine relative to the table in the sewing template machine, the target magnetic force needs to be opposite to the direction of gravity, and the target magnetic force needs to be greater than or equal to the combined force of the gravity of the material frame bracket and the gravity of the material frame module in the sewing template machine.

[0092] When providing working current to the coil assembly in the material frame support device, a relatively large working current can be directly provided to the coil assembly (the working current can be a default setting current, or can be flexibly set according to the suspension height of the material frame support, or according to the gravity of the material frame module and the suspension height of the material frame support at the same time, which is not specifically limited in this embodiment); or the working current provided to the coil assembly can be gradually increased from zero. This embodiment does not specifically limit the specific implementation of step S10.

[0093] When gradually increasing the working current supplied to the coil assembly, the working current supplied to the coil assembly can be gradually increased according to a fixed current increase amount until the working current reaches the target current, or the suspension height of the material frame bracket is detected to reach the target suspension height; or the working current supplied to the coil assembly can be gradually increased according to the current increase amount flexibly determined by using the height difference between the current suspension height of the material frame bracket and the target suspension height, or by using the height difference and the gravity of the material frame module at the same time, until the working current reaches the target current, or the suspension height of the material frame bracket is detected to reach the target suspension height. This embodiment does not specifically limit this.

[0094] The target current may be a default current, or may be flexibly set according to the suspension height of the material frame bracket, or according to both the gravity of the material frame module and the suspension height of the material frame bracket. This embodiment does not specifically limit this.

[0095] On the basis of the above, in a feasible implementation of step S10, steps S11 to S12 may be included:

[0096] Step S11, obtaining the current suspension height of the material frame support;

[0097] It should be noted that the current suspension height refers to the suspension height of the material frame support relative to the platform support at the current moment, which indirectly reflects the suspension height of the material frame module relative to the platform at the current moment. The Hall sensor in the material frame support device can be used to obtain the current suspension height of the material frame support.

[0098] Step S12, providing working current to the coil assembly in the material frame supporting device according to the height difference between the current levitation height and the target levitation height.

[0099] It should be noted that the target suspension height is the suspension height that the material frame support needs to achieve relative to the table support, which indirectly reflects the suspension height that the material frame module needs to achieve relative to the table. When providing working current to the coil assembly in the material frame support device based on the height difference between the current suspension height and the target suspension height, the working current can be provided to the coil assembly in the material frame support device directly by using the height difference; or the working current can be provided to the coil assembly in the material frame support device by using the height difference and other parameters (such as the gravity of the material frame module), which is not specifically limited in this embodiment.

[0100] On the basis of directly using the height difference to provide working current to the coil assembly in the material frame supporting device, when implementing the process of steps S11 to S12, if a larger working current is directly provided to the coil assembly, the mapping relationship between the preset height difference and the working current can be used to first obtain the working current corresponding to the "height difference between the current suspension height and the target suspension height" as the target working current, and then directly provide the target working current to the coil assembly.

[0101] If the working current supplied to the coil component is gradually increased, the mapping relationship between the preset height difference and the current increase amount can be used to obtain the current increase amount corresponding to the "height difference between the current suspension height and the target suspension height" as the target increase amount, and then the target increase amount is used to increase the working current supplied to the coil component, and detect whether the suspension height of the material frame bracket reaches the target suspension height; if not, return to the step of obtaining the current suspension height of the material frame bracket until it is detected that the suspension height of the material frame bracket reaches the target suspension height.

[0102] In this embodiment, the suspension height of the material frame bracket is utilized to provide the coil assembly with a working current adapted to the current suspension height of the material frame bracket. This can not only avoid the situation where the material frame module cannot be suspended due to insufficient working current, but also avoid the situation where excessive working current is provided, resulting in a large gap between the material frame module and the table, affecting the sewing effect.

[0103] On the basis of providing working current to the coil assembly in the material frame supporting device by means of the height difference and the gravity of the material frame module, step S12 may include steps S121 to S122:

[0104] Step S121, obtaining the gravity of the material frame module in the sewing template machine;

[0105] It should be noted that the gravity sensor in the material frame supporting device can be used to obtain the gravity of the material frame module in the sewing template machine.

[0106] Step S122 , providing working current to the coil assembly in the material frame supporting device according to the height difference and the gravity of the material frame module.

[0107] When implementing the process of step S122, if a larger working current is directly provided to the coil assembly, the preset mapping relationship between gravity, height difference and working current can be used to obtain the working current corresponding to the "height difference between the current suspension height and the target suspension height" and the gravity of the material frame module as the target working current, and then the target working current is directly provided to the coil assembly.

[0108] If the working current supplied to the coil component is gradually increased, the preset mapping relationship between gravity, height difference and current increase can be used to obtain the current increase corresponding to the "height difference between the current suspension height and the target suspension height" and the gravity of the material frame module as the target increase. The target increase is then used to increase the working current supplied to the coil component, and detect whether the suspension height of the material frame bracket reaches the target suspension height. If not, the target increase is used to continue to increase the working current supplied to the coil component until it is detected that the suspension height of the material frame bracket reaches the target suspension height.

[0109] In the present embodiment, the suspension height of the material frame bracket and the gravity of the material frame module are simultaneously utilized to provide the coil assembly with a working current that is adapted to both the current suspension height of the material frame bracket and the current gravity of the material frame module. This can not only better avoid the situation where the material frame module cannot be suspended due to insufficient working current, but also better avoid the situation where the gap between the material frame module and the table plate is too large due to excessive working current, thereby affecting the sewing effect.
