Description

Technical Field

[0001] This application relates to the field of sleeve fork processing technology, and in particular to a material suction assembly and a sleeve fork machine. Background Technology

[0002] Currently, the sewing of sleeve vents typically involves folding the corners of small fabric pieces first. Taking a sword-shaped sleeve vent as an example, part of the small fabric piece is folded to form the sword-shaped front of the vent, while another part is folded to form the shape of the back of the vent. However, in the traditional sword-shaped sleeve vent manufacturing process, a clamping mechanism holds the portion of the small fabric piece that forms the back of the vent and folds it upwards towards the sword-shaped portion. Then, a large fabric piece is placed on top of the small fabric piece, with part of the large fabric piece clamped onto the small fabric piece. Finally, the large and small fabric pieces are sewn together to complete the sewing of the sleeve vent.

[0003] However, after folding in this way, the sword-shaped part of the sleeve placket faces downwards. If the entire fabric piece is not flipped over so the sword-shaped part faces upwards, reverse stitching will occur during sewing. This means that neater stitching will appear on the back of the sleeve placket, while the stitching on the front, which needs to be visible, will be messy, prone to problems like bird's nests and loose threads, failing to meet customer requirements. To address this, the applicant proposed a sleeve placket machine structure that allows the sword-shaped part of the smaller fabric piece to be positioned at the top. However, it was found that during processing, the clamping mechanism for holding the sword-shaped part of the smaller fabric piece creates a large gap between itself and the lower worktable. This results in unstable force when it is pressed together with the upper pressure plate, leading to a decrease in the quality of the sleeve placket. Utility Model Content

[0004] Therefore, it is necessary to provide a material suction assembly and a sleeve fork machine to solve the problem that the gap between the clamping mechanism used to hold the sword head and the table surface in the sleeve fork machine leads to a reduction in the processing quality of the sleeve fork.

[0006] In one embodiment, the thickness of the support block along the axial direction of the mounting hole is greater than the thickness of the air intake plate along the axial direction of the mounting hole.

[0007] In one embodiment, the suction assembly further includes a support drive assembly, which is mounted on the end of the suction seat away from the suction plate, and the output end of the support drive assembly is connected to the support block to drive the support block to move.

[0008] In one embodiment, the support drive assembly includes a support fixing plate, a support drive member, and a support follower member.

One end of the support follower member is connected to the support block, and the other end abuts against the output end of the support drive member, so that the support drive member can drive the support follower member and the support block to move.

[0009] In one embodiment, the support follower includes a follower plate and a support rod. The follower plate abuts against the output end of the support drive member. One end of the support rod is connected to the follower plate, and the other end is connected to the support block. A guide groove is provided on the support fixing plate, extending axially along the mounting hole. At least a portion of the follower plate extends into the guide groove and slides in a guide engagement with the guide groove.

[0010] In one embodiment, the support drive assembly further includes a first limiting rod, which is disposed in the guide groove and connected to the support fixing plate; when the support block moves toward the support drive member, the first limiting rod can stop against the driven plate.

[0011] In one embodiment, the support drive assembly further includes a second limiting rod connected to the driven plate; when the support block moves away from the support drive member, the second limiting rod can stop at the suction seat.

[0012] This application also provides a sleeve fork machine for processing sleeve forks, wherein the sleeve fork is formed by sewing together a small piece of fabric and a large piece of fabric, and the small piece of fabric is folded on the sleeve fork machine to form a first shape area and a second shape area, the first shape area forming the front of the sleeve fork and the second shape area forming the back of the sleeve fork; the sleeve fork machine includes a flipping mechanism, a first clamping mechanism, a second clamping mechanism, a lifting assembly, and a suction assembly as described in any of the above embodiments, wherein the first clamping mechanism and the second clamping mechanism are both partially disposed above the suction assembly; the first clamping mechanism is used to clamp the first shape area of ​​the small piece of fabric, the second clamping mechanism is used to clamp the second shape area of ​​the small piece of fabric, the flipping mechanism is connected to the first clamping mechanism and can drive the first clamping mechanism to flip upward toward the second clamping mechanism; wherein, the lifting assembly is used to drive the flipping mechanism, the first clamping mechanism, and the second clamping mechanism to move relative to the suction assembly along the height direction of the sleeve fork machine.

[0015] Compared with the prior art, the suction assembly and sleeve fork machine provided in this application can drive the support block to move upward after the first clamping mechanism is flipped to be directly above the second clamping mechanism, so that the support block abuts against the first clamping mechanism. This can improve the stability of the moving end of the first clamping mechanism and reduce the probability of the moving end of the first clamping mechanism shaking, thereby facilitating the subsequent cooperation with other components and improving the quality of sleeve fork processing.

[0042] Please see Figures 1-18This application provides a sleeve fork machine 100 for processing sleeve forks. The sleeve fork is formed by sewing together a small piece of fabric 200 and a large piece of fabric. The sleeve fork machine 100 includes a folding assembly 50, which is used to process the small piece of fabric 200 forming the sleeve fork by folding the corners of the small piece of fabric 200 into a preset shape. Specifically, the small piece of fabric 200 is folded on the sleeve fork machine 100 by the folding assembly 50 to form a first shape area and a second shape area. The first shape area forms the front of the sleeve fork, and the second shape area forms the back of the sleeve fork. Taking a sword-head sleeve fork as an example, the first shape area is sword-head shaped; taking a square-head sleeve fork as an example, the first shape area is square-head shaped. Of course, the first shape area can also be reasonably changed according to the actual shape of the sleeve fork. The second shape area can be reasonably set to a preset shape as needed, without further limitation here.

[0043] It should be noted that the front of the sleeve vent refers to the outside of the garment that can be directly observed when the sleeve vent is on the garment, while the back of the sleeve vent refers to the inside of the garment. For ease of explanation, this application will only use the processing of sword-head sleeve vents as an example. In this case, the small fabric piece 200 is folded to form a first shape area in the shape of a sword head.

[0044] Currently, after the small piece 200 is folded into the first shape area and the second shape area, the second shape area of ​​the small piece 200 is often clamped by a clamping mechanism, and then folded over the first shape area of ​​the small piece 200. This makes the placement of the large piece relatively simple. The large piece only needs to be placed on top of the second shape area of ​​the small piece 200, and the notch of the large piece is clamped between the first shape area and the second shape area before sewing. However, in this way, the first shape area will be located below the needle relative to the second shape area, which will form reverse stitches during sewing, resulting in poor stitching effect in the exposed first shape area.

[0045] Based on this, to solve the problem that the existing sleeve fork machine 100 easily leads to poor stitching on the front of the sleeve fork during processing, the sleeve fork machine 100 provided in this application includes a folding assembly 20, a processing table, and a lifting assembly 40, with the lifting assembly 40 connected to both the processing table and the folding assembly 20. The folding assembly 20 has a folding surface 201. During folding processing, small fabric pieces 200 are placed on the folding surface 201, and the corners of the small fabric pieces 200 are folded on the folding surface 201 by the folding assembly 50, thereby forming two areas: a first shape area and a second shape area. The lifting assembly 40 can move the folding surface 201 closer to or further away from the processing table to facilitate the placement of large fabric pieces.

[0046] For ease of explanation, this application defines the vertical direction as the height direction of the sleeve opening machine 100; the front-back direction as the width direction of the sleeve opening machine 100, and defines the side facing the operator as the front side and the side facing away from the operator as the back side; the left-right direction as the length direction of the sleeve opening machine 100, and defines the side closer to the operator's left hand as the left side and the side closer to the operator's right hand as the right side.

[0047] Specifically, the folding assembly 20 includes a flipping mechanism 23, a first clamping mechanism 24, and a second clamping mechanism 25, both of which are partially located above the processing table. Specifically, the sleeve-folding machine 100 also includes a suction assembly 30, which provides negative pressure to adsorb the small cut piece 200. Furthermore, to simplify the structure, the suction assembly 30 can be formed into the aforementioned processing table. The suction assembly 30 has a suction surface 301; that is, the first clamping mechanism 24 and the second clamping mechanism 25 are both partially located above the suction surface 301 of the suction assembly 30. The first clamping mechanism 24 is used to clamp a first shape area of ​​the small cut piece 200, and the second clamping mechanism 25 is used to clamp a second shape area of ​​the small cut piece 200. The flipping mechanism 23 is connected to the first clamping mechanism 24 and can drive the first clamping mechanism 24 to flip upwards toward the second clamping mechanism 25. Furthermore, the ends of the first clamping mechanism 24 and the second clamping mechanism 25 closest to the flipping mechanism 23 are defined as fixed ends, and the ends furthest from the flipping mechanism 23 are defined as movable ends. Therefore, the first clamping mechanism 24 has a movable end with a first shape, and the second clamping mechanism 25 has a movable end with a second shape. Correspondingly, the first shape can be the same as the first shape area (e.g., sword-shaped or square-shaped), and the second shape can be the same as the second shape area. The lifting assembly 40 is used to drive the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 to move relative to the processing table (the suction surface 301 of the suction assembly 30) along the height direction of the forklift machine 100.

[0048] Understandably, compared to traditional structures, this application not only adds a first clamping mechanism 24 for holding the first shape area of ​​the small fabric piece 200, but also adjusts the working method of the flipping mechanism 23. That is, this application controls the first clamping mechanism 24 to flip upward toward the second clamping mechanism 25 through the flipping mechanism 23. This design allows the first shape area of ​​the small fabric piece 200 to be folded above the second shape area of ​​the small fabric piece 200. In this way, the first shape area forming the front of the sleeve placket is directly located above, which helps to improve the stitching effect of the front sewing.

[0049] Furthermore, since the first shape area of ​​this application is located above the second shape area, to meet sewing requirements, when placing the large fabric piece, one side of the notch in the large fabric piece needs to be sandwiched between the first and second shape areas, while the other side of the notch needs to be placed between the second shape area and the processing table below (i.e., the suction surface 301 of the suction assembly 30). To this end, this application further provides a lifting assembly 40, which creates a gap between the second clamping mechanism 25 and the processing table below, facilitating the placement of the large fabric piece. This ensures that the large and small fabric pieces 200 can form a front stitch during subsequent sewing, thereby effectively improving the stitch quality on the front of the sleeve placket.

[0050] The first clamping mechanism 24 includes a first fixed clamping plate 241 and a first movable clamping plate 242. The first fixed clamping plate 241 and the first movable clamping plate 242 are distributed vertically along the height direction of the sleeve-opening machine 100, and the first movable clamping plate 242 can move towards or away from the first fixed clamping plate 241, thereby achieving or releasing the clamping of the first shape area of ​​the small fabric piece 200. Similarly, the second clamping mechanism 25 includes a second fixed clamping plate 251 and a second movable clamping plate 252. The second fixed clamping plate 251 and the second movable clamping plate 252 are distributed vertically along the height direction of the sleeve-opening machine 100, and the second movable clamping plate 252 can move towards or away from the second fixed clamping plate 251, thereby achieving or releasing the clamping of the second shape area of ​​the small fabric piece 200. Furthermore, the ends (movable ends) of the first fixed clamping plate 241 and the first movable clamping plate 242 are in a first shape that matches the shape of the first shape area, and the ends (movable ends) of the second fixed clamping plate 251 and the second movable clamping plate 252 are in a second shape that matches the shape of the second shape area.

[0051] In one embodiment, such as Figure 2 and Figure 3 As shown, the flipping mechanism 23 includes a flipping base 231 and a flipping drive 232. The flipping drive 232 is mounted on the flipping base 231, and its output end is connected to the first clamping mechanism 24 to drive the first clamping mechanism 24 to rotate. This facilitates the flipping of the first clamping mechanism 24. The flipping drive 232 can be a motor to improve flipping efficiency and reduce the difficulty of flipping.

[0052] Furthermore, the flipping mechanism 23 also includes a first transmission wheel 233, a second transmission wheel 234, and a transmission belt 235. The first transmission wheel 233 is connected to the output end of the flipping drive 232, the second transmission wheel 234 is connected to the first clamping mechanism 24, and the transmission belt 235 is wound around the first transmission wheel 233 and the second transmission wheel 234, and is drivingly connected to the first transmission wheel 233 and the second transmission wheel 234. In this way, the transmission connection between the flipping drive 232 and the first clamping mechanism 24 can be realized, reducing the transmission difficulty. Moreover, the belt drive system has a simple structure, low manufacturing and installation costs, and can play a role in buffering and absorbing vibration.

[0053] To ensure that the flipping mechanism 23 can brake immediately after the first clamping mechanism 24 has moved into place, in one embodiment, such as Figure 6 As shown, a sensor 243 is connected to the first clamping mechanism 24, and a sensor switch 236 is connected to the flipping base 231. When the first clamping mechanism 24 flips over to be above the second clamping mechanism 25, the sensor switch 236 can engage with the sensor 243. Thus, when the sensor switch 236 senses the signal from the sensor 243, it can control the hooks on the sensor switch 236 to abut against the transmission belt 235, thereby preventing the transmission belt 235 from continuing to rotate and thus braking the flipping mechanism 23.

[0054] Specifically, the flipping mechanism 23 provided in this application has three states: an initial state, a transition state, and a final state. In the initial state, as shown... Figure 2 As shown, the flipping mechanism 23 is not activated, and the first clamping mechanism 24 and the second clamping mechanism 25 are spaced apart along the length of the sleeve-opening machine 100. Then, the flipping mechanism 23 drives the first clamping mechanism 24 to rotate upwards towards the second clamping mechanism 25 by a preset angle and then stops, at which point it behaves as shown in the image. Figure 4 In the transition state shown, there is an angle between the first clamping mechanism 24 and the second clamping mechanism 25 to facilitate the placement of large cut pieces. Afterwards, the flipping mechanism 23 rotates the first clamping mechanism 24 until it is directly above the second clamping mechanism 25, at which point it appears as shown... Figure 5 The final state shown demonstrates the clamping of the large cut piece.

[0055] Furthermore, in the initial state, both the first fixed clamping plate 241 and the second fixed clamping plate 251 are placed on the processing table, and the surfaces of the first fixed clamping plate 241 and the second fixed clamping plate 251 away from the processing table form a folding surface 201. It is easy to understand that when the large cut piece is placed, one side of its notch needs to be clamped between the second fixed clamping plate 251 and the processing table.

[0056] To ensure that one side of the large cut piece at the notch can be smoothly clamped between the second fixed clamping plate 251 and the processing table, in one embodiment, the sleeve-opening machine 100 also includes a worktable 10. The position of the processing table relative to the worktable 10 remains unchanged. The lifting assembly 40 drives the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 to move and cooperate with the worktable 10 along the height direction of the sleeve-opening machine 100. That is, in this embodiment, by keeping the position of the processing table unchanged and raising the first clamping mechanism 24 and the second clamping mechanism 25 by the lifting assembly 40, a gap can be created between the second fixed clamping plate 251 and the processing table, thereby facilitating the placement of the large cut piece.

[0057] In another embodiment, the positions of the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 relative to the worktable 10 remain unchanged, and the lifting assembly 40 drives the processing table to move and cooperate with the worktable 10 along the height direction of the sleeve clamping machine 100. That is, in this embodiment, by keeping the positions of the first clamping mechanism 24 and the second clamping mechanism 25 unchanged and lowering the height of the processing table by the lifting assembly 40, a gap can be created between the second fixed clamping plate 251 and the processing table, thereby facilitating the placement of large pieces of fabric.

[0058] For ease of explanation, this application will use the example of the processing table (the suction surface 301 of the suction assembly 30) remaining in a constant position relative to the worktable 10.

[0059] In one embodiment, such as Figure 3 , Figure 7 and Figure 8 As shown, the lifting assembly 40 is located at the end of the suction assembly 30 opposite to the first fixed clamping plate 241. The lifting assembly 40 includes a lifting base 41 and a lifting drive 42. The flipping mechanism 23 and the second clamping mechanism 25 are both mounted on the lifting base 41. The lifting drive 42 is mounted on one of the lifting base 41 and the worktable 10, and the output end of the lifting drive 42 is connected to the other of the lifting base 41 and the worktable 10. The output end of the lifting drive 42 can apply force to the processing table or the lifting base 41, so that the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 can be raised or lowered relative to the processing table.

[0060] It is understood that the lifting base 41 and the processing table in this embodiment are movably coupled. Thus, when the lifting drive 42 pulls the processing table or the lifting base 41, the lifting drive 42 will drive the lifting base 41 to move closer to the processing table, thereby reducing the distance between the lifting base 41 and the processing table. Since the first fixed clamping plate 241 and the second fixed clamping plate 251 are located above the processing table, the first fixed clamping plate 241 and the second fixed clamping plate 251 will move away from the processing table, thereby achieving a lifting effect. Similarly, when the lifting drive 42 pushes the processing table or the lifting base 41, it will cause the first fixed clamping plate 241 and the second fixed clamping plate 251 to move closer to the processing table, thereby achieving a lowering effect. That is, the lifting assembly 40 can raise and lower the first clamping mechanism 24 and the second clamping mechanism 25 relative to the processing table. Since the small piece 200 is clamped by the first clamping mechanism 24 and the second clamping mechanism 25, the small piece 200 can be raised relative to the processing table along with the first clamping mechanism 24 and the second clamping mechanism 25. During the raising, a gap can be formed between the second fixed clamping plate 251 and the processing table, facilitating the placement of the large piece. After the large piece is placed, the lifting assembly 40 is driven again, lowering the second fixed clamping plate 251 relative to the processing table. Part of the large piece is then clamped between the second fixed clamping plate 251 and the processing table, ensuring the stable position of the large piece relative to the small piece 200. In this way, the function of placing part of the large piece under the small piece 200 is achieved, facilitating the front stitching, and the overall operation is simple, effectively improving the efficiency of sleeve fork processing.

[0061] Optionally, in this embodiment, the lifting drive 42 can be configured as a drive cylinder. Of course, in other embodiments, the lifting drive 42 can also be configured as a linear motor, etc.

[0062] In one embodiment, such as Figure 3 , Figure 7 and Figure 8As shown, the sleeve folding machine 100 also includes a folding base 21, a slide rail 22, and a slide groove 43. A second clamping mechanism 25 is connected to the folding base 21. One of the slide rail 22 and the slide groove 43 is connected to a lifting base 41, and the other is connected to a flipping mechanism 23 and the folding base 21. The slide rail 22 and the slide groove 43 are limited and engaged along the height direction of the sleeve folding machine 100, and are slidably engaged along the width direction of the sleeve folding machine 100. It is easy to understand that, since the slide rail 22 and the slide groove 43 are limited and engaged along the height direction of the sleeve folding machine 100, when the folding base 21 and the flipping mechanism 23 are connected to one of the slide rail 22 and the slide groove 43, they can ensure that they are limited in the vertical direction with the lifting base 41. This allows them to move synchronously when the lifting base 41 moves up and down. That is, the first clamping mechanism 24 connected to the flipping mechanism 23 and the second clamping mechanism 25 connected to the folding base 21 can move up and down synchronously with the movement of the lifting base 41. At the same time, since the slide rail 22 and the slide groove 43 are slidably engaged along the width direction of the sleeve folding machine 100, the first clamping mechanism 24 and the second clamping mechanism 25 can move in the front and back direction. This allows the large and small pieces of fabric to be disengaged after positioning, thus avoiding any adverse effects on the subsequent sewing of the large and small pieces of fabric 200.

[0063] Specifically, in this embodiment, the slide rail 22 is connected to the folding base 21 and the flipping mechanism 23, and the slide groove 43 is connected to the lifting base 41.

[0064] Furthermore, such as Figure 3 As shown, the sleeve-opening machine 100 also includes a telescopic drive component 44, which is mounted on the lifting base 41. The output end of the telescopic drive component 44 is connected to the folding base 21 or the flipping mechanism 23 to drive the folding base 21, the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 to move along the width direction of the sleeve-opening machine 100. In this way, the first clamping mechanism 24 and the second clamping mechanism 25 can be driven in the front-back direction, thereby reducing the driving difficulty.

[0065] Specifically, in this embodiment, the output end of the telescopic drive member 44 is connected to the flipping mechanism 23. Furthermore, the telescopic drive member 44 can be configured as a drive cylinder or a linear motor, etc.

[0066] To facilitate the folding and forming of the first shape area on the small fabric piece 200, in one embodiment, when the sleeve clamping machine 100 is in its initial state, at least a portion of the folding assembly 50 is disposed on the periphery of the end of the first fixed clamping plate 241 away from the flipping mechanism 23. By forming a shape at the end of the first fixed clamping plate 241 that matches the first shape area on the small fabric piece 200, the folding and forming of the first shape area on the small fabric piece 200 is facilitated.

[0067] Specifically, the folding assembly 50 includes two baffles 51, which are spaced apart along the length of the sleeve-opening machine 100. A first fixing plate 241 and a second fixing plate 251 are disposed between the two baffles 51. In this way, the two baffles 51 can provide positioning for folding the two sides of the small fabric piece 200, thereby improving folding efficiency.

[0068] Furthermore, in one embodiment, as Figure 9 and Figure 10 As shown, the folding assembly 50 also includes a left-folding corner assembly 52 and a tilting moving plate assembly 53. In the initial state, the left-folding corner assembly 52 and the tilting moving plate assembly 53 can move to the outer periphery of the ends of the first fixed clamping plate 241 and the second fixed clamping plate 251, and respectively contact and cooperate with the two baffles 51 to form a feeding groove 304. The first fixed clamping plate 241 and the second fixed clamping plate 251 are both disposed in the feeding groove 304. The feeding groove 304 is... Figure 9 The dotted box portion shows that the outer periphery of the feed groove 304 matches the folded edge shape of the sleeve vent, meaning its shape is roughly the same as the combined shape of the first and second shape areas of the sleeve vent. Before folding, the small fabric piece 200 is placed in the feed groove 304 area, such that a portion of the small fabric piece 200 is located between the first fixed clamping plate 241 and the first movable clamping plate 242, the second fixed clamping plate 251 and the second movable clamping plate 252. However, a portion of the small fabric piece 200 is located outside the feed groove 304, and this portion needs to be folded into the feed groove 304 later.

[0069] Therefore, to facilitate the folding of the small cut pieces 200 outside the feeding groove 304 into the feeding groove 304, in one embodiment, such as Figure 11 As shown, the suction assembly 30 is provided with a suction chamber 302 and a plurality of suction holes 303. The suction holes 303 communicate with the suction chamber 302, and when the sleeve clamping machine 100 is in the initial state, the plurality of suction holes 303 are arranged around at least a portion of the outer periphery of the first fixed clamping plate 241 and the second fixed clamping plate 251. That is, the plurality of suction holes 303 are arranged at intervals along the circumference of the feeding groove 304 so that when the suction holes 303 suck air, a portion of the small cut piece 200 forms a crease, so as to facilitate subsequent folding into the outer periphery shape of the feeding groove 304 and improve folding efficiency.

[0070] Furthermore, such as Figure 9 and Figure 10As shown, the left-angle folding assembly 52 includes a left-angle folding plate (not shown), which can rotate toward the feed groove 304 to fold and form the end of one of the first shape area and the second shape area. Simultaneously, the folding assembly 50 also includes a reverse folding assembly 54, which can move toward the feed groove 304 to fold and form the end of the other of the first shape area and the second shape area. Thus, the left-angle folding plate and the left-angle folding assembly 52 cooperate to fold the end of the small cut piece 200, allowing the end of the small cut piece 200 in the first shape area to form a first shape (e.g., a sword tip shape), and providing a preliminary positioning effect.

[0071] Specifically, the material suction assembly 30 includes a suction base 31 and a suction plate 32. The suction plate 32 is mounted on the suction base 31 and together with the suction base 31, forms a suction cavity 302. Suction holes 303 are formed in the suction plate 32, thus facilitating the processing and forming of the suction cavity 302. Furthermore, to facilitate the installation of the material suction assembly 30, the material suction assembly 30 also includes a mounting plate 33. The suction plate 32 is connected to the mounting plate 33 and mounted on the worktable 10 through the mounting plate 33.

[0072] Since this application adopts the method of flipping the first clamping mechanism 24 above the second clamping mechanism 25, and the length of the first clamping mechanism 24 is usually longer than the length of the second clamping mechanism 25, a large gap will be formed between the first moving clamping plate 242 and the suction plate 32 on the first clamping mechanism 24 after the first clamping mechanism 24 is flipped above the second clamping mechanism 25, which is not conducive to subsequent cooperation.

[0073] Based on this, in one embodiment, such as Figures 12-18 As shown, the suction assembly 30 also includes a support block 34. The suction plate 32 has a mounting hole 307. The support block 34 is installed inside the suction chamber 302 and at least partially protrudes from the surface of the suction plate 32 through the mounting hole 307. The outer side wall of the support block 34 is movably engaged with the inner side wall of the mounting hole 307. The support block 34 can move axially along the mounting hole 307 in response to external force to support the movable end of the first clamping mechanism 24, which has flipped above the second clamping mechanism 25. Thus, after the first clamping mechanism 24 flips to be directly above the second clamping mechanism 25, the support block 34 can be driven upwards to abut against the first clamping mechanism 24, improving the stability of the movable end of the first clamping mechanism 24 and reducing the probability of wobbling. This facilitates subsequent cooperation with other components and improves the quality of the sleeve fork processing.

[0074] Specifically, the sleeve fork machine 100 also includes a pressure plate assembly 60, which is located above the material suction assembly 30. The pressure plate assembly 60 includes a pressure plate drive 62 and a serrated pressure plate 61, with the serrated pressure plate 61 connected to the output end of the pressure plate drive 62. When the first clamping mechanism 24 flips to be directly above the second clamping mechanism 25, the serrated pressure plate 61 can move towards the material suction assembly 30 under the drive of the pressure plate drive 62, and cooperate with the support block 34 to clamp the movable end of the first clamping mechanism 24. By pressing the sleeve fork with the pressure plate assembly 60, the movement of the small and large fabric pieces 200 can be avoided when the first and second clamping mechanisms 24 and 25 are pulled out, ensuring the reliability of subsequent sewing. At the same time, the cooperation between the pressure plate assembly 60 and the support block 34 to clamp the movable end of the first clamping mechanism 24 can further ensure the quality of the sleeve fork sword head formation.

[0075] Furthermore, in one embodiment, as Figure 14 , Figure 15 and Figure 16 As shown, the thickness of the support block 34 along the axial direction of the mounting hole 307 is greater than the thickness of the suction plate 32 along the axial direction of the mounting hole 307. This ensures that the support block 34 will not detach from the suction plate 32 during the movement along the axial direction of the mounting hole 307, improving the reliability of the fit between the support block 34 and the suction plate 32, avoiding large gaps between them, and thus preventing adverse effects on air intake.

[0076] To facilitate the movement of the support block 34, in one embodiment, such as Figure 13 and Figure 14 As shown, the suction assembly 30 also includes a support drive assembly 35, which is installed at the end of the suction seat 31 away from the suction plate 32, and the output end of the support drive assembly 35 is connected to the support block 34 to drive the support block 34 to move.

[0077] Specifically, the support drive assembly 35 includes a support fixing plate 351, a support drive member 352, and a support driven member 353. The support fixing plate 351 is mounted on the suction seat 31, and the support drive member 352 is located on the side of the support fixing plate 351 and connected to it. One end of the support driven member 353 is connected to the support block 34, and the other end abuts against the output end of the support drive member 352, so that the support drive member 352 can drive the support driven member 353 and the support block 34 to move. This facilitates the installation of the various components of the support drive assembly 35 and reduces the difficulty of assembly and driving.

[0078] In one embodiment, such as Figure 14 , Figure 15 and Figure 16As shown, the support follower 353 includes a follower plate 3531 and a support rod 3532. The follower plate 3531 abuts against the output end of the support drive member 352. One end of the support rod 3532 is connected to the follower plate 3531, and the other end is connected to the support block 34. That is, the support rod 3532 passes through the suction seat 31 and extends into the suction chamber 302, connecting with the support block 34. The support fixing plate 351 has a guide groove 3501 extending axially along the mounting hole 307. At least a portion of the follower plate 3531 extends into the guide groove 3501 and slides within it. This improves the movement stability of the support follower 353.

[0079] To further improve the reliability of the moving position of the support block 34 and prevent the support block 34 from moving excessively toward the inside of the suction chamber 302, in one embodiment, such as Figure 15 As shown, the support drive assembly 35 also includes a first limiting rod 354, which is disposed within the guide groove 3501 and connected to the support fixing plate 351. When the support block 34 moves toward the support drive member 352, the first limiting rod 354 can stop against the driven plate 3531. It is easy to understand that the first limiting rod 354 can restrict the movement of the support block 34 toward the interior of the suction chamber 302, preventing the support block 34 from detaching from the suction plate 32.

[0080] Similarly, in one embodiment, such as Figure 16 As shown, the support drive assembly 35 also includes a second limiting rod 355, which is connected to the driven plate 3531. When the support block 34 moves away from the support drive member 352, the second limiting rod 355 can stop at the suction seat 31. It is easy to understand that the second limiting rod 355 can restrict the movement of the support block 34 toward the outside of the suction chamber 302, preventing the support block 34 from detaching from the suction plate 32.

[0081] In summary, by controlling the stroke of the support block 34 through the first limiting rod 354 and the second limiting rod 355, the probability of excessive displacement of the support block 34 causing interference with other components (such as the first clamping mechanism 24, the suction seat 31, etc.) can be reduced, thereby effectively improving the reliability of the overall structure. Specifically, to ensure that the serrated pressure plate 61 can be pressed down smoothly, the driving force of the support drive assembly 35 can be set to be less than the driving force of the pressure plate drive component 62. This ensures the clamping force on the sleeve fork during the process of the serrated pressure plate 61 and the support block 34 clamping the first clamping mechanism 24, and achieves stable downward pressing of the serrated pressure plate 61 without additional control, making operation more convenient.

[0082] Similarly, since this application employs a method of flipping the first clamping mechanism 24 above the second clamping mechanism 25, the suction holes 303 on the suction assembly 30 also need to be adapted to meet the suction requirements of the large and small cut pieces 200. Based on this, in one embodiment, as... Figures 11-13 as well as Figure 17 and Figure 18 As shown, the suction assembly 30 has a first region 321, a second region 322, and a third region 323. The first region 321 and the second region 322 are spaced apart along the length of the sleeve-opening machine 100, and the third region 323 and the second region 322 are spaced apart along the width of the sleeve-opening machine 100. Multiple suction holes 303 are provided on each of the first region 321, the second region 322, and the third region 323. When the sleeve-opening machine 100 is in its initial state, the suction holes 303 of the first region 321 correspond to the first clamping mechanism 24, and the suction holes 303 of the second region 322 correspond to the second clamping mechanism 25. When the first clamping mechanism 24 flips over to be above the second clamping mechanism 25, the suction holes 303 of the third region 323 correspond to the movable end of the first clamping mechanism 24. Thus, by controlling the suction of the suction holes 303 in different regions at different stages, the suction of large and small fabric pieces 200 can be effectively achieved, ensuring their stability. For example, during the process of folding the small piece 200 to form the first shape area, the air intake 303 of the first area 321 draws air, causing the small piece 200 to form a crease at that location, thus facilitating folding. Simultaneously, during the process of folding the small piece 200 to form the second shape area, the air intake 303 of the second area 322 draws air, causing the small piece 200 to form a crease at that location, thus facilitating folding. Finally, when the first clamping mechanism 24 flips over to be above the second clamping mechanism 25, the air intake 303 of the second area 322 and the third area 323 draw air, achieving initial adsorption of the sleeve fork, reducing the probability of the large and small pieces 200 forming the sleeve fork scattering or twisting.

[0083] It should be noted that since the second shape area of ​​the small fabric piece 200 is often smaller than the first shape area, after the first shape area is folded over the second shape area, the end of the first shape area cannot be adsorbed in the traditional structure. This application can achieve effective adsorption by adding a suction hole 303 in the third area 323 on the suction assembly 30, thereby improving the quality of sleeve fork forming.

[0084] Specifically, since the small fabric piece 200 in this embodiment is folded to form a first shape and a second shape, to improve the fit, at least some of the suction holes 303 in the first region 321 can be arranged in the first shape, at least some of the suction holes 303 in the second region 322 can be arranged in the second shape, and at least some of the suction holes 303 in the third region 323 can be arranged in the first shape. Thus, a reliable and effective adsorption effect can be provided as needed throughout the entire folding process of the small fabric piece 200.

[0085] As is readily understood, in this embodiment, the first region 321, the second region 322, and the third region 323 are all located on the suction plate 32. Meanwhile, to facilitate the placement of the clamping plates of the first clamping mechanism 24 and the second clamping mechanism 25, in one embodiment, a first receiving groove 305 is recessed on the surface of the suction plate 32. The first receiving groove 305 is located in the first region 321 and is used to place a portion of the first clamping mechanism 24, with at least a portion of the suction holes 303 surrounding the periphery of the first receiving groove 305. That is, the first fixing clamping plate 241 of the first clamping mechanism 24 can be placed within the first receiving groove 305, reducing the height difference between the small piece 200 and the plane of the suction plate 32, thereby further facilitating the folding of the small piece 200. Furthermore, a second receiving groove 306 is formed in the surface recess of the suction plate 32. The second receiving groove 306 is disposed in the second region 322 and the third region 323. The second receiving groove 306 is used to place part of the second clamping mechanism 25, and at least part of the suction holes 303 are arranged in a predetermined shape within the second receiving groove 306. That is, the second fixing plate 251 of the second clamping mechanism 25 can be placed in the second receiving groove 306, reducing the height difference between the small piece 200 and the plane of the suction plate 32, thereby further facilitating the folding of the small piece 200.

[0086] Furthermore, in one embodiment, as Figure 11 As shown, the suction chamber 302 includes a first chamber 3021, a second chamber 3022, and a third chamber 3023. When the sleeve clamping machine 100 is in its initial state, the first chamber 3021 is correspondingly arranged with the first fixing plate 241, and the second chamber 3022 is correspondingly arranged with the second fixing plate 251. When the first clamping mechanism 24 is flipped above the second clamping mechanism 25, the end of the first fixing plate 241 is correspondingly arranged with the third chamber 3023. In this way, the fixing effect of the small fabric piece 200 during the folding process can be ensured.

[0087] Specifically, the first cavity 3021, the second cavity 3022, and the third cavity 3023 are not interconnected. The first cavity 3021 is connected to the air intake 303 of the first region 321, the second cavity 3022 is connected to the air intake 303 of the second region 322, and the third cavity 3023 is connected to the air intake 303 of the third region 323. In this way, each cavity can achieve its own adsorption effect, preventing interference.

[0088] In another embodiment, such as Figure 17 and Figure 18As shown, the suction chamber 302 includes a fourth chamber 3024 and a fifth chamber 3025. The fourth chamber 3024 and the fifth chamber 3025 are not interconnected. The fourth chamber 3024 is connected to the suction port 303 of the first region 321, and the fifth chamber 3025 is connected to the suction ports 303 of the second region 322 and the third region 323. The sleeve fork machine 100 also includes a sealing component that can cooperate with the suction port 303 of the third region 323 to open or close the suction port 303. Thus, the suction port 303 of the third region 323 can be opened or closed as needed by cooperating with the sealing component, achieving the same effect as a three-chamber structure, but with a lower overall cost.

[0089] Specifically, a sealing element can be formed by the left-angle component 52. Typically, the left-angle component 52 is positioned above the suction component 30, and it can move towards the suction plate 32 to seal against the third region 323 on the suction plate 32. Since the left-angle component 52 descends onto the suction plate during the formation of the discharge trough 304, and its position at this time corresponds precisely to the third region 323, forming a sealing element with the left-angle component 52 not only reduces cost but also prevents air from being drawn into the suction hole 303 of the third region 323 during the folding of the small cut piece 200 to form the first and second shape regions, thus avoiding difficulties in the folding operation. Furthermore, when the first shape region of the small cut piece 200 is folded above the second shape region, the left-angle component 52 has already returned to its original position, thus not affecting the suction of the third region 323.

[0090] To further improve the sealing performance of the left corner assembly 52 and the third region 323 on the suction plate 32, in one embodiment, the sleeve fork machine 100 also includes a sealing gasket (not shown). The sealing gasket is disposed between the left corner assembly 52 and the third region 323 on the suction plate 32, and is connected to one or both of the left corner assembly 52 and the suction plate 32. By providing a sealing gasket, the gap between the left corner assembly 52 and the suction plate 32 can be better filled, preventing air from being drawn in through the suction hole 303 of the third region 323 when the left corner assembly 52 and the suction plate 32 are in contact, thus improving the reliability of the structure.

[0091] Specifically, in this embodiment, the sealing gasket can be installed on the third region 323 of the suction plate 32, which is simple to assemble. For example, the support block 34 corresponds to the third region 323 of the suction plate 32, so the sealing gasket can be installed on the upper surface of the support block 34. The sealing gasket can be made of sponge or adhesive tape, etc., and can be reasonably set according to the actual situation.

[0092] Furthermore, when the sealing gasket is installed on the third region 323 of the suction plate 32, the sealing gasket has multiple clearance holes that communicate with the corresponding suction holes 303 on the third region 323. This ensures that after the left-angle assembly 52 is reset, it will not obstruct the suction function of the suction holes 303 in the third region 323.

[0093] This application specifically uses the example of a suction chamber 302 having three cavities. Based on this, the control process of the suction chamber 302 during the folding process of the small fabric piece 200 is as follows:

[0094] When the small piece of fabric 200 begins to fold, the first cavity 3021 and the second cavity 3022 are opened first, and the small piece of fabric 200 is adsorbed through the corresponding air suction hole 303. This fixes the small piece of fabric 200 to prevent positional deviation due to movement, and also facilitates the folding of the outer peripheral corners of the small piece of fabric 200. After the corners of the small piece of fabric 200 are folded and clamped by the first clamping mechanism 24 and the second clamping mechanism 25, the first cavity 3021 is closed while the second cavity 3022 remains open to ensure the stability of the second shape area of ​​the small piece of fabric 200. When the flipping mechanism 23 drives the first clamping mechanism 24 to flip to the transition position, the second cavity 3022 is closed, and the lifting assembly 40 is activated to lift the second fixing plate 251. At this time, the large piece of fabric is placed in. Subsequently, the lifting assembly 40 resets, causing the second fixed clamping plate 251 to descend. When the flipping mechanism 23 drives the first clamping mechanism 24 to flip to the final position, the second cavity 3022 and the third cavity 3023 are opened, thereby achieving stable adsorption of the large and small cut pieces 200 and preventing the positions of the large and small cut pieces 200 from changing when the first clamping mechanism 24 and the second clamping mechanism 25 are withdrawn.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
