[0045] This utility model proposes a sewing device.

[0046] Please see Figures 1 to 3 Combined with reference Figure 10 and Figure 11In one embodiment of this utility model, 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 base plate 31 and a second pressing member. 32. The base plate 31 and the second pressing member 32 are disposed opposite to the push plate assembly 21 in the second direction. The base plate 31 is connected to the frame 1. The second pressing member 32 extends along the first direction and is movably disposed along the third direction. The push plate assembly 21 is used to drive the fabric 200 to move 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 a sewing machine 41. The sewing machine 41 is movably disposed along the first direction to sew the fabric 200 in the sewing gap.

[0047] With this configuration, since the fabric pushing device 2 and the fabric pressing device 3 are fixed in the first direction, sewing does not require moving the fabric pushing device 2 out of the frame 1. This reduces the equipment's footprint and prevents the fabric pushing device 2 from colliding with obstacles. In addition, the fixed configuration of the fabric pushing device 2 in the first direction can prevent loss of accuracy after long-term use and maintain its stability for a long time.

[0048] 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, second, and third directions are orthogonal to each other. In some other embodiments of this utility model, the included angles between the first, second, and third directions are not specifically limited, as long as the function of cooperating between the devices to perform sewing operations is achieved. Furthermore, the push plate assembly 21, the first pressing component 22, and the second pressing component 32 can be driven by corresponding driving devices, such as motors, cylinders, hydraulic mechanisms, etc., 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.

[0049] In one implementation, such as Figure 3 , Figure 9 and Figure 10As 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.

[0050] 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.

[0051] In one implementation, such as Figures 1 to 3 As shown, the sewing device 4 also includes a driver 42 and a guide rail 43. The guide rail 43 is mounted on the frame 1 and extends along a first direction. The sewing machine 41 is movably mounted on the guide rail 43. The driver 42 is mounted on the sewing machine 41 and drivenly connected to the guide rail 43. The driver 42 is used to drive the sewing machine 41 to move along the first direction on the frame 1. It is understood that by setting the guide rail 43, wear caused by the movement of the sewing machine 41 can be reduced, and uneven sewing caused by machine vibration or positional deviation can be avoided. The guide rail 43 can help the sewing machine 41 to accurately align with the fabric 200, especially when performing long-term continuous sewing, which helps to ensure neatness and consistency of the stitches.

[0052] In one embodiment, the number of sewing machines 41 is set to at least two. The two sewing machines 41 move simultaneously to sew the fabric 200, which can further improve the processing efficiency. Of course, in some other embodiments of this utility model, the number of sewing machines 41 can also be three, four, etc., and no specific limitation is made here.

[0053] In one implementation, such as Figures 1 to 3 As shown, at least one end of the guide rail 43 extends out of the frame 1 to form a stopping position for the sewing machine 41. It is understood that the end of the guide rail 43 extending out of the frame 1 to form the 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. The stopping position can be formed at one or both ends of the guide rail 43, and the sewing machine 41 on the guide rail 43 can be placed at the same end or both ends of the guide rail 43.

[0054] In one implementation, such as Figure 1 and Figure 2 As shown, the number of sewing machines 41 is set to two, with both ends of the guide rail 43 extending out of the frame 1 to form stopping positions on both sides of the frame 1. The two stopping positions are used for the two sewing machines 41 to stop. In this embodiment, both ends of the guide rail 43 extend out of the frame 1 to form stopping positions, and the two sewing machines 41 can stop on both sides of the frame 1 when they stop.

[0055] In one implementation, such as Figure 1 and Figure 3 As shown, the sewing device 4 also includes a hinge 46, through which the sewing head 412 is connected to the base 411, allowing the sewing head 412 to be rotatably mounted on the base 411. It is understood that by providing the hinge 46, the operator can rotate the sewing head 412 to a specific angle, facilitating maintenance of the internal structure. For example, the hinge 46 can be configured as a rotatable connection between two links, with the two links respectively rotatably connected to the base 411 and the sewing head 412. Of course, the hinge 46 can also be configured with other structures, which are not specifically limited here.

[0056] 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 bottom plate 31 is connected to the frame 1 through a connector 34. The fabric pressing device 3 also includes a second driving mechanism 33 disposed on the bottom plate 31. The second pressing member 32 is disposed above the bottom 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 bottom plate 31.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] In one embodiment of this utility model, 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 to drive the pusher plate 211 and the tongue plate 212 respectively. Of course, in some other embodiments of this utility model, 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.

[0064] 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 detects 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 detects 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, ensuring the uniformity and consistency of the fabric 200's folds.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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 21 can perform the pushing operation again.

[0069] 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.

[0070] In one implementation, such as Figure 1 As shown, the sewing equipment 100 also includes an electronic control device 5. A protective cover 12 is installed on the frame 1. The fabric pushing device 2, the fabric pressing device 3, and the sewing device 4 are arranged sequentially on the frame 1 along a second direction. The electronic control device 5, the sewing device 4, and the protective cover 12 are arranged sequentially along a third direction. The electronic control device 5 is used to control the fabric pushing device 2, the fabric pressing device 3, and the sewing device 4 to perform sewing operations. This arrangement makes the structure of the sewing equipment 100 compact and reasonably arranged, which helps to reduce space occupation. Furthermore, the electronic control device 5 can efficiently complete the sewing task by controlling the sewing machine 41 and various drive devices (motors, cylinders) to work together.

[0071] The sewing equipment 100 proposed in this utility model operates as follows: 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 electrical 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 towards the pressing device 3 to the preset position. The first pressing component 22 moves upward to release the fabric 200. The tongue plate 212 pushes the fabric 200 to the second pressing device 3. At the preset position between material component 32 and base plate 31, 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 tongue plate 212 move away from the pressing device 3 and back 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 sewing machine 41 moves according to the predetermined parameters and performs 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 tongue plate 212 feed the fabric again, and the next cycle begins until the processing is completed.
