Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, in particular to an auxiliary device for an automatic buttonhole machine for clothing processing. Background Art

[0002] In the complex and delicate production process of garment processing, the automatic buttonhole machine plays a vital role and can be regarded as the key hub of the entire production process. It is like a precise tailor, determining the success or failure of every detail of a garment. The buttonhole on a garment is not only a functional requirement, but also a key factor affecting the overall aesthetics and quality of the garment. Whether it is mass-produced standardized garments or high-end custom garments that require fine processing, the automatic buttonhole machine can ensure the consistency and standardization of the buttonholes, laying a solid foundation for the efficient operation and high-quality output of the garment processing industry.

[0003] However, current automatic buttonhole machines still have some shortcomings in actual use that cannot be ignored. During buttonhole operation, fixing the fabric is often a problem. Due to the lack of an effective fixing mechanism, the fabric is very likely to shift during the buttonhole process. Even a slight deviation in this displacement will lead to inaccurate buttonhole position, seriously affecting the quality of the garment and subsequent processing.

[0004] Moreover, garment processing involves a wide variety of fabrics, with varying thicknesses and materials. Automatic buttonhole machines perform poorly with fabrics of varying thicknesses and materials. For thicker fabrics, problems such as irregular buttonholes and thread breakage may occur due to difficulty penetrating the needle or insufficient thread tension. For thinner fabrics, excessive needle force or uneven material feeding can also lead to uneven buttonhole quality, causing numerous problems for garment processing.

[0005] Therefore, the utility model proposes an automatic buttonhole machine auxiliary device for garment processing. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide an auxiliary device for an automatic buttonhole machine for garment processing.

[0007] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: an automatic buttonhole machine auxiliary device for garment processing, comprising an automatic buttonhole mechanism, the automatic buttonhole mechanism being a concave structure, a pressing and limiting assembly being provided at the top of the lower horizontal end of the automatic buttonhole mechanism, and material guide assemblies being provided on both sides of the lower horizontal end of the automatic buttonhole mechanism;

[0008] The clamping limit assembly includes a mounting frame, which is connected to the automatic lockhole mechanism. The inner wall of the mounting frame is slidably connected to a sliding seat. There are two sliding seats in total, and the sides of the two sliding seats close to each other are rotatably connected to a rotating seat. A pressure roller is provided between the two rotating seats.

[0009] As a preferred embodiment, the pressing roller is covered with a silicone sleeve, and the diameter of the pressing roller is adapted to the diameter of the silicone sleeve.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that by arranging a silicone sleeve on the pressure roller, the friction force of the pressure roller when limiting the fabric can be effectively increased. This silicone sleeve has special physical properties, and its surface has a certain roughness and elasticity, and can fit tightly when in contact with the fabric. In the actual clothing processing process, due to the diversity of fabric materials and the complex processing environment, when the pressure roller squeezes and limits the fabric, if there are no appropriate measures, problems often arise due to the small contact surface. The presence of the silicone sleeve solves this hidden danger very well. It greatly enhances the friction between the pressure roller and the fabric, so that the fabric can be firmly limited during the processing process, thereby effectively avoiding the displacement of the fabric and ensuring the accuracy of processing operations such as buttonholes.

[0011] As a preferred embodiment, springs are provided at both upper and lower ends of the sliding seat, and the other ends of the two springs are respectively connected to the top of the mounting frame and the automatic keyhole mechanism.

[0012] The beneficial effect of adopting the above-mentioned further solution is that under the action of the spring, its unique elastic potential energy provides a stable support force for the pressure roller, so that the pressure roller is always at the appropriate height in the mounting frame. This elastic characteristic of the spring is like an intelligent adjustment system that can automatically adapt to the actual situation. It is worth noting that the length of the lower spring is greater than that of the upper spring. This ingenious design is of great significance. In actual use, this length difference ensures that the pressure roller always maintains a certain distance from the work surface of the automatic buttonhole mechanism. The existence of this distance is carefully considered and creates extremely convenient conditions for loading operations. When loading, the operator does not need to worry about the pressure roller hindering the placement of the fabric. The fabric can be easily and efficiently placed on the workbench and prepared for the subsequent buttonhole process.

[0013] As a preferred embodiment, the mounting frame is slidably connected to a limiting frame above the pressure roller, the limiting frame is a concave structure, a limiting sleeve is provided at the bottom of the limiting frame, and the limiting frame is rotatably connected to both ends of the pressure roller through the limiting sleeve.

[0014] The beneficial effect of adopting the above-mentioned further scheme is: under the precise action of the limiting sleeve, its special structure and the way of cooperating with the pressure roller play a vital and certain limiting role on the pressure roller. When the pressure roller is in the dynamic process of feeding and rotating, the limiting sleeve can strictly limit the range of movement of the pressure roller, and prevent it from the technical problem of tilting and displacement due to various external factors or unbalanced forces generated by its own rotation, thereby ensuring the stability and accuracy of the feeding process. Furthermore, under the reliable action of the limiting frame, since the limiting frame itself has a reasonable mechanical structure and precise guide design, it can ensure that the pressure roller is always in a horizontal state during the up and down sliding process. Whether sliding up or down, the pressure roller can remain horizontal under the constraint of the limiting frame, making the entire processing flow smoother and more stable, laying the foundation for high-quality buttonhole operations and other related processes.

[0015] As a preferred embodiment, the limiting frame is provided with a limiting rod penetrating the mounting frame, and a threaded groove is formed on a top section of the limiting rod.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that through the ingenious setting of the limit rod, it has a unique function in the entire device. During actual use, the operator can manually press the limit rod downward. Due to the special structural design of the limit rod, the section with the threaded groove will contact the mounting frame. This contact method is very critical because the two can be tightly connected through threads. When the limit rod and the mounting frame undergo this threaded connection, a downward force will be generated, which will drive the limit sleeve connected to it to move downward. The limit sleeve and the pressure roller are structurally interrelated, so when the limit sleeve moves downward, the pressure roller will also move accordingly, thereby squeezing and fixing the fabric placed below, ensuring that the fabric remains stable during subsequent processing.

[0017] As a preferred embodiment, the material guide assembly includes a material guide seat, which is connected to the automatic lockhole mechanism. There are two material guide seats in total, and a rotating shaft is provided between the two material guide seats. A rubber roller is rotatably connected to the rotating shaft, and the rubber roller is provided with fault-tolerant holes, and the fault-tolerant holes are distributed in a ring shape.

[0018] The beneficial effect of adopting the above-mentioned further scheme is: under the action of the material guide component, auxiliary displacement and limiting are performed during the fabric processing or adjustment process. When the fabric is placed on the automatic keyhole mechanism, the fabric on both sides of the automatic keyhole mechanism can be placed between the rubber roller and the side wall of the automatic keyhole mechanism. Since the rubber roller is rotatably connected to the rotating shaft, the auxiliary feeding operation can be completed by rotation when adjusting the fabric position. Furthermore, under the action of the fault-tolerant hole, the thickness of the fabric can be further deformed, so that the rubber roller is always in contact with the fabric.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] 1. In the present invention, under the key role of the compression limit assembly, its various components work together to provide a strong guarantee for the automatic buttonhole mechanism to limit the cloth in actual use. The assembly has a sophisticated design and effectively controls the position of the cloth through its internal structure and working principle. When preparing for the buttonhole operation, the fabric needs to be carefully passed through the pressure roller. During this process, the pressure roller will generate a certain amount of pressure and friction on the fabric to help it maintain a stable posture. Afterwards, the fabric is placed in the working area of ​​the automatic buttonhole mechanism. At this time, the operator can manually press the limit rod downward. Due to the special structural design of the limit rod, the section with the threaded groove will contact the mounting frame. This contact method is very critical because the two can be tightly connected through threads. When the limit rod and the mounting frame undergo this threaded connection, a downward force is generated. This force will drive the limit sleeve connected to it to move downward, and the limit sleeve and the pressure roller are structurally interrelated, so when the limit sleeve moves downward, the pressure roller will also move accordingly, thereby squeezing and fixing the fabric placed below, ensuring that the fabric remains stable during subsequent processing.

[0021] 2. In the present invention, the material guide assembly, under the active action of the material guide assembly, effectively assists in the displacement and positioning of the fabric during fabric processing or fabric adjustment. When the fabric is placed on the automatic eyelet mechanism for processing, the fabric on either side of the automatic eyelet mechanism can be accurately positioned between the rubber roller and the side wall of the automatic eyelet mechanism. The rubber roller is rotatably connected to the shaft through a special structural design. This rotational connection gives the rubber roller flexible rotation. Therefore, when the fabric position needs to be adjusted, the operator can easily complete the key operation of assisting the feeding by rotating the rubber roller. Furthermore, the rubber roller is provided with a tolerance hole. This tolerance hole has a significant function. When processing fabrics of different thicknesses, it can deform accordingly to the changes in fabric thickness, thereby ensuring that the rubber roller always closely adheres to the fabric regardless of thickness, ensuring a stable and accurate feeding process.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-4As shown, the utility model provides a technical solution: an auxiliary device for an automatic buttonhole machine for clothing processing, comprising an automatic buttonhole mechanism 1, the automatic buttonhole mechanism 1 is a concave structure, a pressing and limiting assembly 2 is provided at the top of the lower horizontal end of the automatic buttonhole mechanism 1, and material guide assemblies 3 are provided on both sides of the bottom horizontal end of the automatic buttonhole mechanism 1; the pressing and limiting assembly 2 comprises a mounting frame 21, the mounting frame 21 is connected to the automatic buttonhole mechanism 1, a sliding seat 23 is slidably connected to the inner wall of the mounting frame 21, and there are two sliding seats 23, and the sides of the two sliding seats 23 close to each other are rotatably connected to a rotating seat 221, a pressure roller 22 is provided between the two rotating seats 221, and a limiting frame 24 is slidably connected above the pressure roller 22 on the mounting frame 21, and the limiting frame 24 is concave shaped structure, a limiting sleeve 241 is provided at the bottom of the limiting frame 24, and the limiting frame 24 is rotatably connected to the two ends of the pressure roller 22 through the limiting sleeve 241. A limiting rod 242 is provided on the limiting frame 24 and passes through the mounting frame 21. A threaded groove 243 is provided on the top section of the limiting rod 242. Under the key role of the clamping limiting component 2, its various components work together to provide a strong guarantee for the automatic buttonhole mechanism 1 to limit the cloth in actual use. The component has a sophisticated design and effectively controls the position of the cloth through its internal structure and working principle. When preparing for the buttonhole operation, the cloth needs to be carefully passed through the pressure roller 22. During this process, the pressure roller 22 will generate a certain amount of pressure and friction on the cloth to help it maintain a stable posture. Afterwards, the fabric is placed in the working area of ​​the automatic buttonhole mechanism 1. At this time, the operator can manually press the limit rod 242 downward. Due to the special structural design of the limit rod 242, a section thereof with a threaded groove 243 will contact the mounting bracket 21. This contact method is very critical because the two can be tightly connected through threads. When the limit rod 242 and the mounting bracket 21 are threadedly connected, a downward force is generated, which will drive the limit sleeve 241 connected thereto to move downward. The limit sleeve 241 and the pressure roller 22 are structurally interrelated, so when the limit sleeve 241 moves downward, the pressure roller 22 will also move accordingly, thereby squeezing and fixing the fabric placed below, ensuring that the fabric remains stable during subsequent processing, and solving the technical problem of fabric displacement during clothing processing.

[0032] A step further, such as Figure 2-Figure 3As shown, the material guide assembly 3 includes a material guide base 31, which is connected to the automatic keyhole mechanism 1. Two material guide bases 31 are provided, with a rotating shaft 32 disposed between them. A rubber roller 33 is rotatably connected to the rotating shaft 32. The rubber roller 33 is provided with tolerance holes 331 arranged in a circular pattern. The material guide assembly 3 effectively assists in the displacement and positioning of the fabric during processing or adjustment. When the fabric is placed on the automatic keyhole mechanism 1 for processing, the fabric on either side of the mechanism can be accurately positioned between the rubber roller 33 and the sidewall of the mechanism 1. The rubber roller 33 is rotatably connected to the rotating shaft 32 through a special structural design. This type of rotating connection gives the rubber roller 33 the characteristic of flexible rotation. Therefore, when the position of the fabric needs to be adjusted, the operator can easily complete the key operation of auxiliary feeding by rotating the rubber roller 33. Furthermore, a fault-tolerant hole 331 is provided on the rubber roller 33. This fault-tolerant hole 331 has an important function. When processing fabrics of different thicknesses, it can undergo corresponding deformation according to changes in the thickness of the fabric, thereby ensuring that the rubber roller 33 can always fit closely with the fabric regardless of the thickness of the fabric, ensuring the stability and accuracy of the feeding process, and solving the technical problem of wrinkle accumulation during fabric adjustment.

[0033] The above solution also has the problem that the fabric is easily slipped and displaced by simply pressing the fabric with the pressing roller 22. Figure 4 As shown: In this solution, a silicone sleeve 222 is provided on the pressure roller 22, and the diameter of the pressure roller 22 is adapted to the diameter of the silicone sleeve 222. By providing the silicone sleeve 222 on the pressure roller 22, the friction force of the pressure roller 22 when limiting the cloth can be effectively increased. This silicone sleeve 222 has special physical properties, and its surface has a certain roughness and elasticity, and can fit tightly when in contact with the cloth. In the actual clothing processing process, due to the variety of cloth materials and the complex processing environment, when the pressure roller 22 squeezes and limits the cloth, if there are no appropriate measures, problems often arise due to the small contact surface. The presence of the silicone sleeve 222 solves this hidden danger very well. It greatly enhances the friction between the pressure roller 22 and the cloth, so that the cloth can be firmly limited during the processing process, thereby effectively avoiding the displacement of the cloth and ensuring the accuracy of processing operations such as buttonholes.

[0034] The above solutions still have the problem of inconvenience in loading materials, such as Figure 4As shown: In this embodiment, springs 231 are provided at both ends of the sliding seat 23. The other ends of the two springs 231 are connected to the top of the mounting frame 21 and the automatic keyhole mechanism 1, respectively. Under the action of the springs 231, their unique elastic potential energy provides a stable support force for the pressure roller 22, so that the pressure roller 22 is always at the appropriate height within the mounting frame 21. This elastic characteristic of the springs 231 is like an intelligent adjustment system that can automatically adapt to actual conditions. It is worth noting that the length of the lower spring 231 is greater than that of the upper spring 231. This ingenious design is of great significance. In actual use, this length difference ensures that the pressure roller 22 always maintains a certain distance from the work surface of the automatic keyhole mechanism 1. The existence of this distance is carefully considered and creates extremely convenient conditions for loading operations. When loading, the operator does not need to worry about the pressure roller 22 hindering the placement of the fabric. The fabric can be easily and efficiently placed on the work surface, ready for the subsequent keyhole process.

[0035] Working principle:

[0036] like Figure 1-4 As shown, first, the device needs to be placed in the designated position. This designated position must ensure that the device is in a horizontal and stable state, and the surrounding environment meets the processing requirements so that subsequent operations can be carried out smoothly. Secondly, the fabric to be processed passes through the rubber rollers 33 on both sides and under the pressure roller 22. This process requires the operator to operate carefully to ensure that the fabric passes through these components smoothly and smoothly. Then, the fabric is placed in the processing area of ​​the automatic buttonhole mechanism 1. This area has precise dimensions and markings to guide the placement of the fabric to ensure the accuracy of the buttonhole position. After placement is completed, the operator presses the limit rod 242 downward with appropriate force to make it initially contact with the mounting frame 21, and then proceeds. The rotation operation is performed. At this time, under the action of the thread groove 243, a tight threaded connection is formed between the limit rod 242 and the limit frame 24. When the limit rod 242 rotates, due to the transmission effect of the thread, the distance between the limit frame 24 and the mounting frame 21 will gradually decrease. In this process, the limit sleeve 241 is driven by the limit frame 24 to push the pressure roller 22 downward. The pressure roller 22 will gradually apply pressure to the fabric until the fabric is tightly squeezed and fixed. After the fixation is completed, the automatic keyhole mechanism 1 is turned on. Before turning it on, the parameters of the keyhole mechanism need to be checked and set, such as the shape, size, spacing, etc. of the keyhole. Then the automatic keyhole mechanism 1 starts to work and accurately processes the fabric.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
