[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] This invention proposes a sewing device 100.

[0052] Please see Figures 1 to 3 Combined with reference Figure 10 , Figure 11 In one embodiment of the present invention, the sewing device 100 includes a frame 1 and a fabric pushing device 2, a fabric pressing device 3, and a sewing device 4 disposed on the frame 1. The fabric pushing device 2 includes a push plate assembly 21 and a first pressing member 22. The push plate assembly 21 extends along a first direction and is movably disposed along a second direction to drive the fabric 200 to move along the second direction. The first pressing member 22 is movably disposed above the push plate assembly 21 along a third direction to limit and press the fabric 200 onto the push plate assembly 21. The first direction, the second direction, and the third direction intersect each other. The fabric pressing device 3 includes a device disposed opposite to the push plate assembly 21 in the second direction. The second pressing member 32 extends along the first direction and is movably arranged along the third direction. The push plate assembly 21 is used to move the fabric 200 between the frame 1 and the second pressing member 32. The second pressing member 32 is used to cooperate with the frame 1 to clamp the fabric 200. The fabric pushing device 2 and the fabric pressing device 3 are used to clamp the fabric 200 respectively and are spaced apart to form a sewing gap. The sewing device 4 includes at least two sewing machines 41. At least two processing areas are formed on the frame 1 along the first direction. Each processing area is provided with a sewing machine 41. The sewing machine 41 is movably arranged along the first direction to sew the fabric 200 in the sewing gap.

[0053] With this setup, the processing efficiency can be greatly improved by having at least two sewing machines 41 move simultaneously. Furthermore, since the pusher device 2 and the presser device 3 are fixed in the first direction, sewing does not require the pusher device 2 to be moved out of the frame 1, which reduces the equipment's footprint and volume, and avoids collisions between the pusher device 2 and obstacles. In addition, the fixed setting of the pusher device 2 in the first direction can prevent loss of accuracy after long-term use and improve its stability.

[0054] It should be noted that, as Figure 1 As shown, in this embodiment, the first direction is the length direction of the frame 1, the second direction is the width direction of the frame 1, and the third direction is the height direction. The first direction, the second direction, and the third direction are orthogonal to each other. In some other embodiments of the present invention, the included angles between the first direction, the second direction, and the third direction are not specifically limited, as long as the function of the various devices cooperating to perform sewing operations is achieved. The processing area can be divided according to the length of the push plate assembly 21 and the second pressing component 32 in the first direction. For example, in one embodiment, the number of sewing machines 41 is set to two, which can be divided into two corresponding processing areas along the first direction, with one sewing machine 41 set in each processing area. If the number of sewing machines 41 is set to three, it can be divided into three processing areas along the first direction, and so on. The number of sewing machines 41 can be set according to the requirements.

[0055] Furthermore, the pusher assembly 21, the first pressing component 22, and the second pressing component 32 can be driven by corresponding drive devices, such as motors, cylinders, and hydraulic mechanisms, which can be selected according to actual needs and are not specifically limited here. In addition, the sewing machine 41 can be constrained to move in the first direction by structures such as slide rails and grooves to improve processing accuracy.

[0056] In one implementation, such as Figures 1 to 3 As shown, the sewing equipment 100 also includes an electronic control device 5, and the sewing equipment 4 also includes a driver 42. The sewing machine 41 is connected to the frame 1 via the driver 42. The driver 42 is used to drive the sewing machine 41 to move along a first direction on the frame 1. The electronic control device 5 is electrically connected to the sewing machine 41 and the driver 42. The electronic control device 5 is used to control the movement of the sewing machine 41 within the corresponding processing area and to perform sewing operations. It should be noted that, in this embodiment, the driver 42 can be configured as a stepper motor, servo motor, or other component with precise position control. By controlling the driver 42 to drive the sewing machine 41 to move, the electronic control device 5 can improve the sewing accuracy of the fabric 200. Furthermore, from... Figure 1 As can be seen, the electronic control device 5 is located below the sewing machine 41, which helps to improve the space utilization of the sewing equipment 100.

[0057] In one implementation, such as Figures 1 to 3As shown, the sewing device 4 also includes a guide rail 43, which is mounted on the frame 1 and extends along a first direction. The sewing machine 41 is movably mounted on the guide rail 43. At least one end of the guide rail 43 extends out of the frame 1 and forms a stopping position for the sewing machine 41 to stop. It is understood that by setting the guide rail 43, the friction between the sewing machine 41 and the frame 1 can be reduced and the sewing accuracy can be improved. The end of the guide rail 43 extending out of the frame 1 to form a stopping position allows the sewing machine 41 to be moved to the stopping position when it stops working, facilitating operation and maintenance by the operator. One or both ends of the guide rail 43 can form a stopping position, and the sewing machine 41 on the guide rail 43 can be parked at the same end or both ends of the guide rail 43.

[0058] In one implementation, such as Figure 1 and Figure 2 As shown, the frame 1 has two processing areas along the first direction. Two sewing machines 41 are provided, each located within one of the two processing areas. The guide rails 43 extend from both ends of the frame 1, forming stopping positions on both sides of the frame 1. These two stopping positions are used for the two sewing machines 41 to stop. In this embodiment, both ends of the guide rails 43 extend from the frame 1 to form stopping positions. When stopped, the two sewing machines 41 can rest on either side of the frame 1. During operation, the two sewing machines 41 can sew the fabric 200 in the two processing areas, resulting in high efficiency and convenient operation.

[0059] In one implementation, such as Figure 3 As shown, the sewing device 4 includes a mounting plate 44 and two guide rails 43 spaced apart in a second direction. The sewing machine 41 is slidably connected to the two guide rails 43 via the mounting plate 44. It can be understood that by positioning the sewing machine 41 above the mounting plate 44 and connecting the two guide rails 43 via the mounting plate 44, the stability of the sewing machine 41's movement can be improved, ensuring its processing accuracy.

[0060] In one implementation, such as Figure 3 and Figure 9 As shown, the driver 42 includes a stepper motor 421 mounted on the sewing machine 41, a rack 431 on the guide rail 43 along a first direction, and a gear 422 meshing with the rack 431 on the output shaft of the stepper motor 421. The stepper motor 421 drives the gear 422 to rotate, thereby moving the sewing machine 41. The stepper motor 421 is mounted on the mounting plate 44 with its output shaft extending downwards and connected to the gear 422. The rack 431 is located on the side of the guide rail 43 facing the gear 422, and the gear 422 meshes with the rack 431. When the stepper motor 421 drives the gear 422 to rotate, it can move the mounting plate 44 and the sewing machine 41 on it along the guide rail 43. It can be understood that the stepper motor 421 enables precise positioning of the sewing machine 41, allowing the sewing machine 41 to precisely sew the fabric 200 within the processing area.

[0061] In one implementation, such as Figure 3 , Figure 9 and Figure 10 As shown, the sewing machine 41 includes a base 411 and a head 412 disposed on the base 411. A clearance channel 41a extending in a first direction and a notch communicating with the clearance channel 41a are formed between the head 412 and the base 411. The notch is disposed towards the fabric pushing device 2. A sewing needle 413 is disposed on the head 412 at the notch. The clearance channel 41a is used for at least part of the fabric pressing device 3 to pass through when the sewing machine 41 moves. The sewing head 412 has an L-shaped bend on the base 411 and its end extends toward the fabric pushing device 2. A sewing needle 413 is provided at the notch formed between the end of the sewing head 412 near the fabric pushing device 2 and the base 411. When the sewing machine 41 moves, part of the structure of the fabric pressing device 3 passes through the clearance channel 41a. The sewing needle 413 can sew the fabric 200 between the fabric pressing device 3 and the fabric pushing device 2. It can be understood that setting the clearance channel 41a can improve the space utilization of the equipment. Its notch is used to avoid the connection structure between the frame 1 and the fabric pressing device 3, so that the sewing needle 413 can enter the corresponding processing area.

[0062] In one implementation, such as Figures 4 to 6 , Figures 9 to 11 As shown, the fabric pushing device 2 also includes a first driving mechanism 23. The push plate assembly 21 includes a push plate 211 and a tongue plate 212 that are driven and connected to the first driving mechanism 23 respectively. The first driving mechanism 23 is used to drive the push plate 211 and the tongue plate 212 to move along the second direction respectively. The frame 1 is provided with a base plate 31, which is connected to the frame 1 through a connector 34. The fabric pressing device 3 also includes a second driving mechanism 33 provided on the base plate 31. The second pressing member 32 is provided above the base plate 31 and driven and connected to the second driving mechanism 33. The second driving mechanism 33 is used to drive the second pressing member 32 to move along the third direction. The tongue plate 212 is used to push the fabric 200 between the second pressing member 32 and the base plate 31.

[0063] It should be noted that, please refer to Figure 11The first drive mechanism 23 is used to independently drive the pusher plate 211 and the tongue plate 212. When pushing the fabric, the fabric 200 can be laid on the tongue plate 212 first, and the first pressing member 22 is controlled to press the fabric 200 on the tongue plate 212. The first drive mechanism 23 drives the pusher plate 211 and the tongue plate 212 to move towards the pressing device 3 and stop at a predetermined position. The first pressing member 22 is controlled to release the fabric 200, and the first drive mechanism 23 drives the tongue plate 212 again to shape the fabric 200. The folded foot is pushed between the second pressing member 32 and the base plate 31. The second driving mechanism 33 drives the second pressing member 32 to press down and cooperates with the base plate 31 to clamp the folded foot of the fabric 200. The first driving mechanism 23 drives the tongue plate 212 away from the pressing device 3 to a predetermined position, and cooperates with the first pressing member 22 to press the fabric 200 located above the tongue plate 212, so that the pushing device 2 and the pressing device 3 press the fabric 200 at the same time and form a sewing gap between them. At this time, the sewing machine 41 can move to perform sewing operations.

[0064] In one implementation, such as Figures 4 to 7 As shown, a mounting platform 11 is provided on the frame 1. A pusher plate 211 is slidably mounted on the mounting platform 11, and a tongue plate 212 is movably mounted above the pusher plate 211. A first drive mechanism 23 is located below the mounting platform 11 and is drivenly connected to both the pusher plate 211 and the tongue plate 212. It should be noted that the pusher plate 211 is movably mounted on the upper surface of the mounting platform 11, and the tongue plate 212 is movably mounted on the upper surface of the pusher plate 211. Figure 4 As shown, the mounting platform 11 is provided with a perforated structure so that the power output structure of the first drive mechanism 23 can pass through the mounting platform 11 and connect to the push plate 211 and the tongue plate 212 respectively. The first drive mechanism 23, the mounting platform 11 and the push plate assembly 21 are arranged in sequence along the third direction, which can reduce the space occupation of the equipment and achieve high transmission efficiency.

[0065] In one implementation, such as Figure 6 and Figure 7 As shown, the first drive mechanism 23 includes a first motor 231, a first transmission shaft 232 arranged in a first direction, and a first guide shaft 233 arranged in a second direction. The first guide shaft 233 is provided with a movable first connecting seat 234. The first motor 231 is driven to the first transmission shaft 232, the first transmission shaft 232 is driven to the first connecting seat 234, and the first connecting seat 234 is connected to the pusher plate 211. The first connecting seat 234 is used to drive the pusher plate 211 to move.

[0066] It should be noted that in this embodiment, the number of first drive shafts 232 is set to two and arranged at intervals along the second direction. The first motor 231 is set between the two first drive shafts 232 and connected to one of the first drive shafts 232 through a drive belt (not shown). Each of the two first drive shafts 232 is provided with a pulley (not shown). A first belt (not shown) is wound around the two pulleys and fixedly connected to the first connecting seat 234. When the first motor 231 works, it can drive the two first drive shafts 232 to rotate through the drive belt and the first belt, thereby driving the first connecting seat 234 to move along the second direction on the first guide shaft 233. The first connecting seat 234 passes through the mounting platform 11 and is connected to the pusher plate 211, which can push the pusher plate 211 to move.

[0067] In one implementation, such as Figure 6 and Figure 7 As shown, the first drive mechanism 23 also includes a second motor 235, a second transmission shaft 236 arranged in a first direction, and a second guide shaft 237 arranged in a second direction. The second guide shaft 237 is provided with a movable second connecting seat 238. The second motor 235 is driven to the second transmission shaft 236, the second transmission shaft 236 is driven to the second connecting seat 238, and the second connecting seat 238 is connected to the tongue plate 212. The second connecting seat 238 is used to drive the tongue plate 212 to move.

[0068] It should be noted that in this embodiment, the number of second drive shafts 236 is set to two and arranged at intervals along the second direction. The second motor 235 is set between the two second drive shafts 236 and connected to one of the second drive shafts 236 through a drive belt (not shown). The two second drive shafts 236 are provided with pulleys 239. The second belt (not shown) is wound around the two pulleys 239 and fixedly connected to the second connecting seat 238. When the second motor 235 works, it can drive the two second drive shafts 236 to rotate through the drive belt and the second belt, thereby driving the second connecting seat 238 to move along the second direction on the second guide shaft 237. The tongue plate 212 is connected to the second connecting seat 238 passing through the mounting platform 11 through the connecting plate 213. The second connecting seat 238 can then push the tongue plate 212 to move.

[0069] In one embodiment of the present invention, the first drive mechanism 23 includes two sets of drive components corresponding to the first motor 231 and the second motor 235, respectively. The two sets of components are arranged at intervals along the second direction at the bottom of the mounting platform 11. The two motors are electrically connected to the electronic control device 5 to drive the pusher plate 211 and the tongue plate 212 respectively. Of course, in some other embodiments of the present invention, the first motor 231 and the first transmission shaft 232, and the second motor 235 and the second transmission shaft 236 can be configured as direct drive, gear meshing drive, etc., without specific limitations. In addition to belt drive, the first transmission shaft 232 and the first connecting seat 234, and the second transmission shaft 236 and the second connecting seat 238 can also be driven by bevel gear and rack, without specific limitations, as long as the driving function can be achieved.

[0070] In one implementation, such as Figure 7 As shown, the fabric pushing device 2 also includes a first sensor 24 mounted on the frame 1, which is used to detect the position of the first connecting seat 234. Furthermore, the fabric pushing device 2 also includes a second sensor 25 mounted on the frame 1, which is used to detect the position of the second connecting seat 238. It can be understood that the first sensor 24 and the second sensor 25 can precisely control the moving distance of the fabric pushing plate 211 and the tongue plate 212, and, in conjunction with the electronic control device 5, adjust the moving parameters of the fabric pushing plate 211 and the tongue plate 212 to ensure the uniformity and consistency of the fabric 200 folds.

[0071] In one implementation, such as Figure 5 , Figure 6 ,and Figure 10 As shown, the fabric pushing device 2 also includes a guide post 26 and a first cylinder 27. The guide post 26 is disposed on the fabric pushing plate 211 and extends in a third direction. The first pressing member 22 is slidably disposed on the guide post 26 and located above the tongue plate 212. The first cylinder 27 is drivenly connected to the first pressing member 22 and is used to drive the first pressing member 22 to move along the guide post 26. It should be noted that there are two guide posts 26, which are spaced apart. The first pressing member 22 forms an L-shaped bending structure on the side facing the fabric pressing device 3. When the cylinder pushes the first pressing member 22 to move up and down, it can press or release the fabric 200 located on the tongue plate 212 to prevent the fabric 200 from being displaced when the pusher assembly 21 pushes. The first pressing member 22 is also used to work with the second pressing member 32 to clamp the fabric 200 simultaneously to improve the processing quality.

[0072] In one implementation, such as Figures 8 to 10As shown, the second drive mechanism 33 includes a second cylinder 331 mounted on the base plate 31 and a transmission assembly 332 drivenly connected to the second cylinder 331. The second pressing member 32 is drivenly connected to the transmission assembly 332. The second cylinder 331 is used to drive the second pressing member 32 closer to or further away from the base plate 31 via the transmission assembly 332. It should be noted that the transmission assembly 332 can be configured as a connecting rod, a rotating arm, or other structures. Its rotation axis can be constrained by a rotating shaft so that the second pressing member 32 can move upward in a third direction. The structure of the transmission assembly 332 is not specifically limited here and can be set according to actual needs.

[0073] In one implementation, such as Figure 5 , Figure 6 and Figure 10 As shown, the fabric pushing device 2 also includes a fabric scraping mechanism 28. The fabric scraping mechanism 28 includes a bracket 281, a third drive mechanism 282 mounted on the bracket 281, and a fabric scraping component 283. The third drive mechanism 282 is driven to connect with the fabric scraping component 283. The third drive mechanism 282 is used to drive the fabric scraping component 283 into the sewing gap so that the sewn fabric 200 can be removed from the pressing device 3. It should be noted that after the sewing machine 41 completes the sewing operation on the fabric 200 in the sewing gap, the second pressing component 32 releases the fabric 200 located on the base plate 31. At this time, the fabric 200 may remain on the base plate 31 and not fall off, which may interfere with the subsequent transfer of the fabric 200. The fabric scraping component 283 is a long strip-shaped structure. The third drive mechanism 282 drives the fabric scraping component 283 into the sewing gap to remove the fabric 200 from the base plate 31 and move it downwards for subsequent operations.

[0074] In one implementation, such as Figure 5 , Figure 6 and Figure 10 As shown, the third drive mechanism 282 includes a third cylinder 2821 mounted on a bracket 281 and a swing arm assembly 2822. The bracket 281 is mounted on the push plate assembly 21. The third cylinder 2821 is connected to the fabric scraper 283 via the swing arm assembly 2822. The third cylinder 2821 is used to drive the fabric scraper 283 into the sewing gap via the swing arm assembly 2822. It can be understood that the bracket 281 is mounted on the push plate 211 so that the fabric scraper mechanism 28 can move along the second direction following the push plate 211. The swing arm assembly 2822 includes a connecting rod assembly and a corresponding linkage shaft. The linkage shaft is arranged along the first direction and is driven by both the connecting rod assembly and the third cylinder 2821. The third cylinder 2821 drives the linkage shaft to rotate around its axis, so that the trajectory of the fabric scraper 283 driven by the connecting rod assembly is arc-shaped. Please refer to [reference needed]. Figure 10 The fabric scraper 283 can move from above the first pressing member 22 towards the obliquely downward side of the pressing device 3 to scrape the fabric 200 in the sewing gap downward so that the pusher assembly can perform the pushing operation again.

[0075] In addition, such as Figure 4 and Figure 5 As shown, multiple pressing cylinders 271 are also provided at intervals on the linkage shaft of the swing arm assembly 2822. The pressing cylinders 271 are used to press the first pressing member 22 so that the first pressing member 22 has multiple force application points to ensure the pressing effect of the first pressing member 22 on the fabric 200.

[0076] This invention also proposes a sewing equipment control method, which is applied to the sewing equipment 100 in any of the foregoing embodiments. Specifically, the electronic control device 5 in the sewing equipment 100 includes a controller and a memory. The memory stores the control program of the sewing equipment 100. The controller executes the control program to control the sewing equipment 100 to perform the following method. Please refer to [link to relevant documentation]. Figure 12 Based on the sewing equipment 100 described above, the sewing equipment control method proposed in this invention includes, but is not limited to, steps S10, S20, and S30:

[0077] S10: Control the push plate assembly to move the fabric 200 between the frame 1 and the second pressing component 32, and control the second pressing component 32 to press the fabric 200 onto the frame 1;

[0078] S20: Control the pusher assembly to move away from the second pressing member 32 to a predetermined position, and control the first pressing member 22 to press the fabric 200 on the pusher assembly;

[0079] S30: Control the two sewing machines 41 to move simultaneously and sew the fabric 200 between the first pressing element 22 and the second pressing element 32.

[0080] Specifically, before step S10, the sewing equipment 100 of the present invention needs to perform some operations. After the equipment is turned on, the sewing machine 41, the fabric pushing device 2, and the fabric pressing device 4 will automatically reset to the preset initial position. The fabric 200 is manually laid on the fabric pushing plate 211 and the tongue plate 212. The electronic control device 5 is pre-set with operating parameters to control the sewing machine and the drive devices (motors, cylinders) of each mechanism to operate in coordination. The operation is started by triggering the control switch (button touch, foot pedal, etc.): the first cylinder 27 drives the first pressing component 22 to press the fabric 200 on the tongue plate 212. The fabric pushing plate 211 and the tongue plate 212 push the fabric 200 to the preset position in the direction close to the fabric pressing device 3. The first pressing component 22 moves upward to release the fabric 200. The tongue plate 212 pushes the fabric 200 to the second pressing component 32 and the bottom plate 3. At the preset position between 1 (base plate 31 is part of frame 1), the second cylinder 331 controls the second pressing component 32 to press the fabric 200 onto the base plate 31. The pusher plate 211 and the tongue plate 212 move away from the pressing device 3 to the stop position, so that a sewing gap is formed between the pusher device 2 and the pressing device 3. The first pressing component 22 presses the fabric 200 on the tongue plate 212. The two sewing machines 41 move in the corresponding processing area according to the predetermined parameters and perform sewing operations on the fabric 200 in the sewing gap. After sewing is completed, the sewing machine 41 returns to the initial position. The second pressing component 32 releases the fabric 200 on the base plate 31. The third cylinder 2821 controls the scraper component 283 to scrape the fabric 200 on the base plate 31 to the bottom. Then, the pusher plate 211 and the tongue plate 212 feed the fabric again, and the next cycle begins until the processing is completed.

Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
