Description

Technical Field

[0001] This utility model relates to the field of bag-applying machine technology, specifically to a feeding and folding mechanism for a bag-applying machine. Background Technology

[0002] With industrial development, the level of automation in garment processing is increasing. In pocket sewing, patch pocket machines have emerged on the market to replace complex manual operations. Patch pocket machines are mainly used in the sewing of pockets on clothing such as denim, workwear, and shirts.

[0003] Application publication number CN119640508A discloses an improved bag-applying machine, specifically comprising a frame and a worktable, a folding module, a feeding module, a feeding and unfeeding module, and a sewing machine head, all mounted on the frame and cooperating with each other. The folding module includes a folding positioning seat, a folding cylinder mounted on the frame for driving the folding positioning seat up and down, and a pressing assembly, a bag bottom folding assembly, two bag edge folding assemblies, and two upper bag corner folding assemblies, all mounted on the folding positioning seat and cooperating with each other. The pressing assembly includes components detachably mounted to the bottom of the folding positioning seat via a quick-release screw. The bag pressing plate has a pressing groove on its bottom surface that corresponds to the shape of the pocket fabric. The bag bottom folding assembly includes a bag bottom folding cylinder that is adjustable left and right and mounted on the left end of the folding positioning seat, and a bag bottom folding piece that is adjustable up and down and connected to the output shaft of the bag bottom folding cylinder and located below the pressing plate. Two bag edge folding assemblies are located on opposite sides of the middle of the folding positioning seat. Each bag edge folding assembly includes a bag edge folding cylinder that is adjustable front and back and mounted on the folding positioning seat, and a bag edge folding piece that is adjustable up and down and connected to the output shaft of the bag edge folding cylinder and located below the pressing plate. The two upper pocket corner folding assemblies are respectively located on the right side of the folding positioning seat. Each upper pocket corner folding assembly includes an upper pocket corner folding cylinder that is adjustable back and forth and mounted on the folding positioning seat, and an upper pocket corner folding piece that is adjustable up and down and connected to the output shaft of the upper pocket corner folding cylinder and located below the bag pressing plate. By adjusting the positions of the bottom pocket folding piece, the side pocket folding piece, and the upper pocket corner folding piece, the folding module can be used to fold pocket fabrics of different sizes and thicknesses. The feeding module includes a feeding positioning seat mounted on the frame, a movable plate that can move up and down, and a feeding positioning seat mounted on the frame. The system includes a loading cylinder for driving the movable plate to move up and down, a loading cylinder for moving left and right on the movable plate, and a loading template located below the pressing plate and capable of moving left and right under the loading cylinder. The loading template is used to place pocket fabric so that the folding module can fold it. The feeding and unloading module is used to transport the workpiece folded by the folding module and the loading module to the sewing machine head on the worktable for subsequent sewing. The feeding and unloading module can also be used to transport the workpiece sewn by the sewing machine head to the unloading port on the worktable for unloading.

[0004] However, the improved bag-applying machine described above still has some drawbacks. For example, as can be clearly seen from the attached diagram, for the folding positioning seat on the folding module, which connects the pressing component, the bottom folding component, two side folding components, and two upper corner folding components, a slide rail assembly needs to be added between the folding positioning seat and the frame support to ensure the stability of its movement. This constitutes the first limiting structure. Furthermore, for the movable plate of the feeding module, to ensure its stability during movement, the four corners of the movable plate need to be movably fitted onto the four guide posts of the fixed base. This constitutes the second limiting structure. Thus, the folding module and the feeding module each use a limiting structure to achieve the movement stability of the folding positioning seat and the feeding positioning seat, respectively. However, this structure is relatively complex and not conducive to disassembly and assembly.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

In other words, this utility model simplifies the structure, facilitates disassembly and assembly, and makes inspection and maintenance convenient.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

In other words, this utility model simplifies the structure and is also convenient for disassembly, assembly, inspection and maintenance. Attached Figure Description

[0031] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0032] like Figures 1-5 As shown, a feeding and folding mechanism for a bag-applying machine includes a fixed frame 1, a main drive device 2, a folding assembly 3, and a feeding assembly 4.

[0033] like Figure 1 As shown, the mounting bracket 1 is fixedly installed and the main drive unit 2 is mounted on the mounting bracket 1.

[0034] like Figures 1-4 As shown, the feeding assembly 4 includes a movable plate 41 that is longitudinally movable and connected to the output end of the main drive device 2, a feeding drive device 42 mounted on the movable plate 41, and a feeding template 43 that is laterally movable and mounted on the output end of the feeding drive device 42.

[0035] like Figure 1 , Figure 2 As shown, the folding assembly 3 includes a folding drive device 31 connected to the movable plate 41, a folding fixing seat 32 that is longitudinally movable and connected to the output end of the folding drive device 31 and located above the feeding template 43, and a folding structure 33 correspondingly installed on the folding fixing seat 32.

[0036] like Figure 1 , Figure 5As shown, a first slide rail assembly 5 is provided between the folding edge fixing seat 32 and the fixing frame 1. The first slide rail assembly 5 includes a first slide rail 51 mounted on the fixing frame 1 and a first slider 52 that is longitudinally movably mounted on the first slide rail 51 and whose outer end is connected to the folding edge fixing seat 32. Through the above arrangement, the first slide rail 51 mounted on the fixing frame 1 and the folding edge fixing seat 32 can effectively improve the guiding accuracy of the longitudinal movement of the folding edge fixing seat 32 and prevent the folding edge fixing seat 32 from being displaced unexpectedly in the lateral and other directions.

[0037] In summary, existing technologies require the movable plate 41 to be movably mounted on the four guide posts of the fixed frame 1 at its four corners. The present invention uses a main drive device 2 fixedly mounted on the fixed frame 1. The output end of the main drive device 2 is connected to the movable plate 41 of the feeding assembly 4. The feeding assembly 4 is connected to the folding assembly 3. The first slide rail assembly 5 is connected to the folding fixing seat 32 of the folding assembly 3 and the fixed frame 1, respectively. This allows the folding fixing seat 32 and the movable plate 41 to achieve stable longitudinal movement through only one limiting structure (the first slide rail assembly 5) during movement. Therefore, the present invention simplifies the structure, facilitates disassembly and assembly, and makes maintenance convenient.

[0038] like Figure 1 , Figure 2 As shown, there are two main drive units 2, and the output ends of the two main drive units 2 are respectively connected to both sides of the movable plate 41. By connecting the output ends of the main drive units 2 to both sides of the movable plate 41, the structure becomes more stable and its position is less likely to deviate after the two main drive units 2 are connected to the movable plate 41.

[0039] The main drive unit 2 is a cylinder. The advantage of using a cylinder is that it has a simple structure, strong overload resistance, and is easy to replace and maintain.

[0040] like Figure 2 , Figure 4 As shown, the output end of the feeding drive device 42 is connected to the feeding template 43 via a connecting block 44; a second slide rail assembly 45 is provided between the connecting block 44 and the movable plate 41; the second slide rail assembly 45 includes a second slide rail 451 mounted on the movable plate 41 and a second slider 452 that is laterally movably mounted on the second slide rail 451 and whose outer end is connected to the connecting block 44. This arrangement effectively improves the guiding accuracy of the lateral movement of the feeding template 43, preventing unexpected displacement of the feeding template 43 in the longitudinal and other directions.

[0041] The feeding drive device 42 is a cylinder. Similarly, the advantage of using a cylinder is that it has a simple structure, strong overload resistance, and is easy to replace and maintain.

[0042] like Figure 2 , Figure 3 As shown, the output end of the folding drive device 31 is connected to the folding fixing seat 32 via an inverted L-shaped plate 34; the horizontal end of the inverted L-shaped plate 34 is connected to the output end of the folding drive device 31, and the vertical end of the inverted L-shaped plate 34 is connected to the folding fixing seat 32. Similarly, through the above arrangement, the folding drive device 31 can be connected to the folding fixing seat 32.

[0043] The hemming drive device 31 is a cylinder. Similarly, the advantage of using a cylinder is that it has a simple structure, strong overload resistance, and is easy to replace and maintain.

[0044] like Figure 2 As shown, the feeding assembly 4 also includes a limiting plate 46 and a connecting plate 47; there are two limiting plates 46, both on the movable plate 41, and each limiting plate 46 has a transversely penetrating limiting hole 48; the connecting plate 47 is engaged in the limiting hole 48; the folding drive device 31 is mounted on the connecting plate 47; therefore, the output ends of the two main drive devices 2 and the folding drive device 31 are actually connected to the movable plate 41 through the limiting plate 46 and the connecting plate 47. With the above arrangement, each limiting plate 46 wraps around the connecting plate 47, providing limiting and stable support for the movement of the connecting plate 47 within the limiting hole 48, thereby enabling the movable plate 41 to move more stably longitudinally, and the connecting plate 47 can penetrate the limiting plate 46 transversely through the limiting hole 48, making installation and disassembly more convenient.

[0045] like Figure 2 As shown, the folding structure 33 includes a pressing assembly 331, a bottom folding assembly 332, two side folding assemblies 333, and two upper corner folding assemblies 334 that cooperate with each other. Since the above configuration is prior art, it will not be described in detail here.

[0046] The following describes the specific working principle of this utility model in order to help you understand it:

[0047] First, after starting the equipment, the feeding drive cylinder 42 drives the feeding template 43 to extend, and then the pocket fabric is placed on the feeding template 43.

[0048] Next, the folding drive device 31 drives the folding positioning seat 32 to move downward until the pressing component 331 covers the feeding template 43 and the electromagnet (not shown in the figure) of the energized pressing component 331 generates a magnetic attraction force on the feeding template 43, thereby fixing the pocket fabric.

[0049] Next, the bottom folding assembly 332, the side folding assembly 333, and the top corner folding assembly 334 operate in sequence, thereby forming folds on the bottom, side, and top corner of the pocket fabric.

[0050] Next, the main drive unit 2 drives the hem retainer 32 and the movable plate 41 to move downwards accordingly until the pocket fabric moves to the position of the trouser leg fabric;

[0051] Next, the upper pocket corner folding assembly 334, the pocket edge folding assembly 333, and the pocket bottom folding assembly 332 are reset in sequence so that the folded parts of the pocket fabric are matched and stacked on the trouser leg fabric.

[0052] Finally, the feeding drive cylinder 42 drives the feeding template 43 to retract so that it leaves the pocket fabric.

[0053] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
