Description

Technical Field

[0001] This application relates to the field of sleeve fork processing technology, and in particular to 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 tip of the sleeve placket faces down. If the entire fabric piece is not turned over so that the sword-shaped tip faces up, reverse stitching will occur during sewing. This means that the neater stitching will appear on the back of the sleeve placket, while the stitching on the front of the sleeve placket, which needs to be shown, will be messy, prone to problems such as bird's nests and loose threads, making it difficult to meet customer requirements. However, turning the fabric piece over requires manual or machine operation, which not only greatly affects processing speed but also further increases the overall cost. Utility Model Content

[0004] Therefore, it is necessary to provide a sleeve fork machine to solve the problem of low efficiency of existing sleeve fork machines when folding sleeves.

[0005] This application provides a sleeve fork machine, which includes a processing table, a folding assembly, and a lifting assembly. The folding assembly has a folding surface, and the folding surface, the processing table, and the lifting assembly are arranged sequentially along the height direction of the sleeve fork machine. The lifting assembly includes a lifting base and a lifting drive. The lifting base is connected to the folding assembly, and the lifting drive is installed on one of the lifting base and the processing table. The output end of the lifting drive is connected to the other of the lifting base and the processing table. The output end of the lifting drive can apply force to the processing table or the lifting base to raise or lower the folding surface relative to the processing table.

[0006] In one embodiment, the lifting assembly further includes a guide post, a guide hole is provided on the lifting base, the guide post is inserted into the guide hole and slides and guides with the inner wall of the guide hole, and one end of the guide post is connected to the processing table; wherein, the axial direction of the guide post and the guide hole is parallel to the axial direction of the lifting drive component.

[0007] In one embodiment, the lifting assembly further includes a linear bearing, at least a portion of which is mounted in the guide hole, and the guide post passes through the linear bearing and slides in a guiding engagement with the linear bearing.

[0008] In one embodiment, the outer periphery of the linear bearing protrudes to form a connecting portion, which is fixedly connected to the lifting base.

[0009] In one embodiment, the lifting assembly further includes a limiting member connected to the end of the guide column away from the processing table, and the limiting member can cooperate with the linear bearing stop to prevent the lifting base from moving away from the processing table.

[0010] In one embodiment, there are multiple guide posts, which are spaced circumferentially around the lifting drive member.

[0011] In one embodiment, the lifting assembly further includes a floating joint, one end of which is connected to the processing table and the other end of which is connected to the output end of the lifting drive.

[0012] In one embodiment, the lifting base includes a first fixed plate, a second fixed plate, and a support column. The first fixed plate is disposed on the side of the second fixed plate away from the processing table, and the two ends of the support column are respectively connected to the first fixed plate and the second fixed plate. The lifting drive is connected to the first fixed plate, and the output end of the lifting drive passes through the first fixed plate and the second fixed plate in sequence and is connected to the processing table.

[0013] In one embodiment, the lifting base further includes a third fixing plate and a connecting plate. The third fixing plate is disposed on the side of the second fixing plate away from the processing table, and the two ends of the connecting plate are respectively connected to the second fixing plate and the third fixing plate; wherein, the material bending assembly is connected to the third fixing plate.

[0014] In one embodiment, the folding assembly includes a flipping mechanism, a first clamping mechanism, and a second clamping mechanism. 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 first clamping mechanism and the second clamping mechanism form the folding surface.

[0015] In one embodiment, the sleeve fork machine further includes a worktable, the processing table remains at a constant position relative to the worktable, and the lifting assembly drives the flipping mechanism, the first clamping mechanism, and the second clamping mechanism to move and cooperate with the worktable along the height direction of the sleeve fork machine; or, the flipping mechanism, the first clamping mechanism, and the second clamping mechanism remain at a constant position relative to the worktable, and the lifting assembly drives the processing table to move and cooperate with the worktable along the height direction of the sleeve fork machine.

[0016] In one embodiment, the sleeve fork machine further includes a suction assembly that forms the processing table and is used to provide negative pressure.

[0017] Compared with the prior art, the sleeve-opening machine provided in this application, when the lifting drive pulls the processing table or the lifting base, will cause the lifting drive to move the lifting base closer to the processing table, thus reducing the distance between the lifting base and the processing table. Since the folding assembly is connected to the lifting base and the folding surface is located above the processing table, the folding surface and the processing table will move away from each other, thereby achieving a lifting effect. Similarly, when the lifting drive pushes the processing table or the lifting base, it will cause the folding surface and the processing table to move closer together, thereby achieving a lowering effect. That is, the processing table and the folding assembly are connected by a lifting assembly, which can be used to raise and lower the folding surface relative to the processing table. Furthermore, during the raising process, a gap can be formed between the folding surface and the processing table. Since small pieces of fabric are placed on the folding surface, they can be raised relative to the processing table along with the folding surface, thus facilitating the placement of large pieces of fabric. After the large piece of fabric is placed, the lifting assembly is activated again, lowering the folding surface relative to the processing table. Part of the large piece of fabric is then sandwiched between the folding surface and the processing table, ensuring the large piece of fabric is stably positioned relative to the small piece of fabric. This achieves the function of placing the large piece of fabric under the small piece of fabric, facilitating the creation of front-side stitches. The overall operation is simple and effectively improves the efficiency of sleeve placket processing. Attached Figure Description

[0032] 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.

[0033] However, after folding in this way, the sword-shaped tip of the sleeve placket faces down. If the entire fabric piece is not turned over so that the sword-shaped tip faces up, reverse stitching will occur during sewing. This means that the neater stitching will appear on the back of the sleeve placket, while the stitching on the front of the sleeve placket, which needs to be shown, will be messy, prone to problems such as bird's nests and loose threads, making it difficult to meet customer requirements. However, turning the fabric piece over requires manual or machine operation, which not only greatly affects processing speed but also further increases the overall cost.

[0034] Please see Figures 1-6To address the issue of low efficiency in folding sleeve forks in existing sleeve fork machines, this application provides a sleeve fork machine 100. This machine 100 is used to process sleeve forks and can form front stitches on the sleeve forks. The sleeve forks are formed by folding small fabric pieces 200 and sewing them to a large fabric piece.

[0035] Please continue reading. Figure 2 and Figure 3 The sleeve folding machine 100 includes a folding assembly 20 and a processing table. The folding assembly 20 has a folding surface 201. During the folding process, small cut pieces 200 are placed on the folding surface 201 to fold their corners, thus forming two areas: a first shape area and a second shape area. The first shape area ultimately forms the front of the sleeve fold, which can be sword-shaped or square-shaped, etc. The second shape area ultimately forms the back of the sleeve fold, and its shape can be reasonably set according to actual needs, without being limited here.

[0036] 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.

[0037] 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.

[0038] Currently, when sewing sleeve gussets, since the second shape area of ​​the small fabric piece 200 is located above the first shape area, the large fabric piece can be placed directly above the small fabric piece 200 and held between the second and first shape areas at the notch of the large fabric piece before sewing. However, in this way, the first shape area is located below the needle relative to the second shape area, resulting in reverse stitches and poor stitching effect in the exposed first shape area. To achieve right-side stitches, the large fabric piece needs to be inserted between the small fabric piece 200 and the processing table. Based on this, in this application, the sleeve gusset machine 100 also includes a lifting assembly 40, and the folding surface 201, the processing table, and the lifting assembly 40 are arranged sequentially along the height direction of the sleeve gusset machine 100. The lifting assembly 40 includes a lifting base 41 and a lifting drive 42. The lifting base 41 is connected to the folding assembly 20, and the lifting drive 42 is mounted on one of the lifting base 41 and the processing table. The output end of the lifting drive 42 is connected to the other of the lifting base 41 and the processing table. The output end of the lifting drive 42 can apply force to the processing table or the lifting base 41, so that the folding surface 201 can be raised or lowered relative to the processing table.

[0039] Understandably, when the lifting drive 42 pulls the processing table or the lifting base 41, the lifting drive 42 will cause 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 folding assembly 20 is connected to the lifting base 41 and the folding surface 201 is located above the processing table, the folding surface 201 and the processing table will move away from each other, thus achieving the lifting effect. Similarly, when the lifting drive 42 pushes the processing table or the lifting base 41, it will cause the folding surface 201 and the processing table to move closer to each other, thereby achieving the lowering effect. That is, the processing table and the folding assembly 20 are connected by the lifting assembly 40. The lifting assembly 40 can raise and lower the folding surface 201 relative to the processing table. During raising, a gap is created between the folding surface 201 and the processing table. Since the small cut piece 200 is placed on the folding surface 201, it can be raised along with the folding surface 201 relative to the processing table, facilitating the placement of the large cut piece. After the large cut piece is placed, the lifting assembly 40 is driven again, lowering the folding surface 201 relative to the processing table. Part of the large cut piece is then sandwiched between the folding surface 201 and the processing table, ensuring the stable position of the large cut piece relative to the small cut piece 200. This achieves the function of placing the large cut piece below the small cut piece 200, facilitating front stitching, and the overall operation is simple, effectively improving the efficiency of sleeve fork processing.

[0040] It should be noted that, since this application can place the large piece of fabric below the small piece of fabric 200 through the lifting component 40, the existing folding method of the small piece of fabric 200 can be changed. That is, when the small piece of fabric 200 is folded, the first shape area of ​​the small piece of fabric 200 can be manipulated to fold upward toward the second shape area, so that the sword tip of the sleeve placket is facing upward, and thus a right-side stitch can be formed during sewing, which greatly improves the sewing effect of the sleeve placket.

[0041] In one embodiment, such as Figures 3-5 As shown, the lifting assembly 40 also includes a guide post 46. A guide hole 4121 is provided on the lifting base 41. The guide post 46 is inserted into the guide hole 4121 and slides in a guiding engagement with the inner wall of the guide hole 4121. One end of the guide post 46 is connected to a processing table. The axial directions of the guide post 46 and the guide hole 4121 are parallel to the axial direction of the lifting drive component 42. By providing the guide post 46, the stability of the movement of the lifting base 41 can be further improved.

[0042] To further improve the reliability of the lifting base 41 moving along the guide post 46, in one embodiment, the lifting assembly 40 further includes a linear bearing 47, at least a portion of which is installed within the guide hole 4121, and the guide post 46 passes through the linear bearing 47 and slides in a guiding engagement with it. It is easy to understand that the linear bearing 47 not only provides stable support for the movement of the lifting base 41 relative to the guide post 46, preventing swaying or deviation, but also reduces friction between the lifting base 41 and the guide post 46, thereby greatly improving transmission efficiency.

[0043] In one embodiment, a connecting portion 471 protrudes from the outer periphery of the linear bearing 47. The connecting portion 471 is fixedly connected to the lifting base 41, thereby improving the connection stability between the linear bearing 47 and the lifting base 41. Simultaneously, it prevents the linear bearing 47 from detaching from the lifting base 41, thus improving the overall structural reliability. Here, the connecting portion 471 can be detachably connected using fasteners such as bolts or screws, facilitating subsequent disassembly and maintenance.

[0044] Furthermore, the lifting assembly 40 also includes a limiting member 48, which is connected to the end of the guide column 46 away from the processing table. The limiting member 48 can cooperate with the linear bearing 47 to stop and prevent the lifting base 41 from moving away from the processing table. In this way, it can prevent the lifting base 41 from moving excessively downward, thereby preventing the lifting base 41 from disengaging from the guide column 46. In addition, it can also position the relative position between the folding surface 201 and the processing table, avoiding excessive force between the corresponding parts and reducing the risk of interference damage to the parts.

[0045] The limiting member 48 can be made of polyurethane or rubber to provide a certain buffering effect, which helps to reduce the impact generated when the linear bearing 47 comes into contact with the limiting member 48.

[0046] To further improve the stability of the lifting base 41 during movement, in one embodiment, there are multiple guide posts 46, which are spaced apart circumferentially around the lifting drive member 42. The number of linear bearings 47 and limiting members 48, which cooperate with the guide posts 46, can correspond one-to-one with the number of guide posts 46.

[0047] For example, in this embodiment, the number of guide posts 46 is set to two, and the two guide posts 46 are symmetrically arranged relative to the lifting drive member 42. Of course, the number of guide posts 46 can also be set to three or four, etc.

[0048] In one embodiment, such as Figure 4 and Figure 5 As shown, the lifting assembly 40 also includes a floating joint 421, one end of which is connected to the processing table, and the other end is connected to the output end of the lifting drive 42. This facilitates the connection between the lifting drive 42 and the processing table, and the floating joint 421 can reduce the eccentric load caused by installation errors, thereby preventing damage to the lifting drive 42 and effectively improving the stability of equipment operation.

[0049] Optionally, in this embodiment, the lifting drive 42 is configured as a drive cylinder. Of course, in other embodiments, the lifting drive 42 may also be configured as a linear motor, etc.

[0050] In one embodiment, such as Figures 3-5 As shown, the lifting base 41 includes a first fixing plate 411, a second fixing plate 412, and a support column 413. The first fixing plate 411 is located on the side of the second fixing plate 412 away from the processing table. The two ends of the support column 413 are respectively connected to the first fixing plate 411 and the second fixing plate 412. The lifting drive component 42 is connected to the first fixing plate 411, and its output end passes through the first fixing plate 411 and the second fixing plate 412 sequentially and connects to the processing table. Thus, the area of ​​the first fixing plate 411 can be smaller than that of the second fixing plate 412, reducing the overall space occupied by the lifting base 41 within the same stroke range of the lifting drive component 42, thereby improving space utilization.

[0051] Furthermore, in one embodiment, the lifting base 41 further includes a third fixing plate 414 and a connecting plate 415. The third fixing plate 414 is located on the side of the second fixing plate 412 away from the processing table, and the two ends of the connecting plate 415 are respectively connected to the second fixing plate 412 and the third fixing plate 414. The folding assembly 20 is connected to the third fixing plate 414. This provides better support for the folding assembly 20, improves the installation stability of the folding assembly 20, and reduces the risk of interference between components.

[0052] Specifically, one of the third fixing plate 414 and the folding assembly 20 is provided with a slide rail 43, and the other is provided with a slide groove 44. The slide rail 43 is slidably mounted on the slide groove 44, and the slide groove 44 can restrict the movement of the slide rail 43 in the vertical direction of the sleeve-opening machine 100, thereby ensuring that the lifting base 41 can drive the folding assembly 20 to rise and fall synchronously through the slide rail 43 and the slide groove 44. At the same time, the slide rail 43 can also move in the front-back direction of the sleeve-opening machine 100 within the slide groove 44 to realize the insertion and extension of the folding assembly 20.

[0053] In this embodiment, the chute portion 44 is connected to the third fixing plate 414, and the slide rail portion 43 is connected to the folding assembly 20. The chute portion 44 can be integrally formed on the third fixing plate 414, or it can be fixedly connected by welding or other methods.

[0054] Furthermore, to enable the folding assembly 20 to extend and retract along the slide rail portion 43 and the slide groove portion 44, such as... Figure 3 As shown, the sleeve fork machine 100 also includes a telescopic drive component 45, which is mounted on a second fixed plate 412 on the lifting base 41. The output end of the telescopic drive component 45 is connected to the folding assembly 20 to drive the folding assembly 20. The axial direction of the telescopic drive component 45 is parallel to the extension direction of the slide rail portion 43 and the slide groove portion 44 to improve driving stability.

[0055] Specifically, the folding assembly 20 includes a first clamping mechanism 24, a second clamping mechanism 25, a flipping mechanism 23, a folding base 21, and two baffles 22. The two baffles 22 are spaced apart in the left-right direction and are both connected to the folding base 21. The first clamping mechanism 24 is connected to the flipping mechanism 23, and the second clamping mechanism 25 is connected to the folding base 21. Both the flipping mechanism 23 and the folding base 21 are connected to the lifting base 41 via a slide rail 43 and a slide groove 44. Furthermore, the first clamping mechanism 24 is used to clamp the first shape area of ​​the small cut piece 200, the second clamping mechanism 25 is used to clamp the second shape area of ​​the small cut piece 200, and 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.

[0056] Furthermore, the first clamping mechanism 24 includes a first fixed clamping plate 241 and a first movable clamping plate 242, which cooperate to clamp the first shaped area of ​​the small cut piece 200. The second clamping mechanism 25 includes a second fixed clamping plate 251 and a second movable clamping plate 252, which cooperate to clamp the second shaped area of ​​the small cut piece 200.

[0057] The first clamping mechanism 24 and the second clamping mechanism 25 form a folding surface 201. Specifically, in the initial state, the upper surfaces of the first fixed clamping plate 241 of the first clamping mechanism 24 and the second fixed clamping plate 251 of the second clamping mechanism 25 cooperate to form the folding surface 201, facilitating the placement and subsequent clamping of the small cut piece 200. At this time, the first movable clamping plate 242 is tilted relative to the first fixed clamping plate 241, and the second movable clamping plate 252 is tilted relative to the second fixed clamping plate 251, to facilitate the placement of the small cut piece 200.

[0058] When the sleeve folding machine 100 is working, it first places the small piece of fabric 200 on the processing table and folds the corners of the small piece of fabric 200 by manual operation or other parts, thereby forming a second shape area and a first shape area on the small piece of fabric 200. Then, the first movable clamping plate 242 rotates and cooperates with the first fixed clamping plate 241 to clamp the first shape area of ​​the small piece of fabric 200. The second movable clamping plate 252 rotates and cooperates with the second fixed clamping plate 251 to clamp the second shape area of ​​the small piece of fabric 200, preventing the corners of the small piece of fabric 200 from falling off. Afterwards, the flipping mechanism 23 drives the first clamping mechanism 24 to rotate upwards towards the second clamping mechanism 25 by a preset angle. Then, the lifting drive 42 applies force to the processing table to reduce the distance between the lifting base 41 and the processing table, thereby moving the lifting base 41 upwards. This simultaneously drives the folding assembly 20 upwards, creating a height difference between the folding surface 201 and the processing table. At this time, a large piece of fabric is placed in the table, with one side of the notch on the large piece of fabric positioned below the second fixed clamping plate 251, and the other side of the notch positioned between the second shape area and the first shape area on the small piece of fabric 200. Then, the lifting drive 42 is activated again, causing the folding assembly 20 to return to its original position. One side of the large cut piece notch is then clamped between the second fixed clamping plate 251 and the processing table. At this time, the flipping mechanism 23 continues to drive the first clamping mechanism 24 to rotate upwards towards the second clamping mechanism 25, causing the first moving clamping plate 242 to cooperate with the second moving clamping plate 252 to clamp the other side of the large cut piece notch. Afterwards, the pressure plate mechanism presses down on the large and small cut pieces 200, and causes the folding assembly 20 to extend in the front-to-back direction. Finally, the pressure plate mechanism returns to its original position to facilitate subsequent sewing. In this way, the sleeve gusset can be positioned with the sword tip facing upwards, allowing for the formation of a right-side stitch during subsequent sewing, thereby optimizing the stitch effect of the sleeve gusset.

[0059] In one embodiment, such as Figure 1 As shown, the sleeve fork 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 fork machine 100.

[0060] For example, such as Figure 5 and Figure 6 As shown, the processing table can be fixedly installed on the worktable 10 so that the lifting base 41 and the folding surface 201 can be raised or lowered relative to the worktable 10 and the processing table under the drive of the lifting drive member 42. It is easy to understand that since the worktable 10 is relatively fixed, the processing table connected to the worktable 10 is also relatively fixed. On this basis, when the lifting drive member 42 is driven, the position of the processing table will not change, which will cause the lifting base 41 to rise or fall relative to the processing table, thereby driving the folding assembly 20 to rise or fall relative to the worktable 10.

[0061] Of course, in other embodiments, the positions of the flipping mechanism 23, the first clamping mechanism 24, and the second clamping mechanism 25 relative to the worktable 10 can remain unchanged, and the lifting assembly 40 can drive the processing table to move and cooperate with the worktable 10 along the height direction of the sleeve fork machine 100. In this case, since the position of the lifting base 41 relative to the worktable 10 remains unchanged, the lifting drive 42 will directly drive the processing table to rise and fall relative to the worktable 10 when it is driven.

[0062] To further ensure the reliability of the small fabric pieces 200 during the folding process, the sleeve folding machine 100 also includes a suction assembly 30, which provides negative pressure to adsorb the small fabric pieces 200. Furthermore, to simplify the structure, the suction assembly 30 can be formed into the aforementioned processing table.

[0063] Specifically, the suction assembly 30 is provided with a suction surface 301, and the first fixing plate 241 and the second fixing plate 251 are both partially placed above the suction surface 301.

[0064] 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.

[0065] 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.
