Description

Technical Field

[0001] This utility model relates to the field of garment production and processing technology, specifically to an automatic sewing device for concealed buttons on clothing. Background Technology

[0002] A snap fastener typically consists of two parts: a male and a female. The male is usually a raised section, while the female is a matching recess. These two parts, through a specific structural design, can be tightly joined together to achieve the desired connection. To use a snap fastener, simply align the male with the female and press gently to connect them securely. This connection method is not only convenient and quick but also very strong, capable of withstanding a certain amount of tension and pressure. To separate the snap fasteners, a gentle pull or press is all that's needed. Due to their compact, concealed, and practical features, snap fasteners are widely used in various fields. In clothing, snap fasteners are commonly used to connect collars, cuffs, and other parts, making the garment more aesthetically pleasing. The main functions of snap fasteners on clothing include decoration, fastening, and protection. When sewing snap fasteners, the male fastener is sewn first, and after sewing, a crease is pressed along the overlapping area. Then, the female fastener is sewn in place around the crease. In current garment processing, snap fasteners are generally sewn manually. Manual sewing of snap fasteners has the following drawbacks: First, the snap fasteners are too small to hold easily, making them prone to falling off during sewing, resulting in low sewing efficiency, high labor intensity, and high sewing difficulty. Second, the sewing holes on the snap fasteners are very small, making manual sewing difficult and slow. Furthermore, the thread is difficult to knot, causing the snap fasteners to easily come undone, resulting in poor appearance quality. Therefore, it is objectively necessary to develop an automatic snap fastener sewing device with a reasonable structural design, high degree of automation, and the ability to improve both sewing speed and quality. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic sewing device for garment snap buttons that has a reasonable structural design, a high degree of automation, and can improve both sewing speed and sewing quality.

[0004] The purpose of this utility model is achieved as follows: It includes a base and an automatic sewing machine mounted on the base. A button-attaching mold is installed on the base below the automatic sewing machine. The button-attaching mold includes a movable support, a fixed template, and a movable template. The size of the movable template is smaller than that of the fixed template. The movable support is slidably mounted on the base. A translation driver connected to the movable support is installed on the side of the base away from the automatic sewing machine. The fixed template is fixedly mounted on the movable support, and the movable template is located above the fixed template. One end of the movable template is slidably connected to the movable support. A fixed frame is installed on the top of the movable support, and a lifting driver connected to the movable template is installed on the fixed frame. The other end of the movable template is machined with a snap fastener placement groove that cooperates with the automatic sewing machine. A pressing component that cooperates with the snap fastener placement groove is installed on the movable template.

[0005] Compared to traditional manual sewing, this device has the following advantages: First, it upgrades and modifies the existing automatic sewing machine's structure by incorporating a snap-fit ​​mold on the machine base. During use, the garment is placed between the fixed and movable templates. A lifting driver moves the movable template downwards to secure the garment. Then, the worker manually places the snap fastener into the snap fastener slot. A translation driver then pushes the fixed and movable templates below the automatic sewing machine, allowing the machine to automatically sew the snap fastener in. This snap-fit ​​mold not only reduces labor intensity but also increases the speed and efficiency of snap-fit ​​sewing. This device improves production efficiency and solves the problem of difficult sewing of small snap buttons, significantly reducing the difficulty of snap button sewing and effectively improving the strength of snap button sewing. Secondly, the clamping component can press the snap buttons in the snap button placement slot to prevent them from shifting during movement, ensuring that the snap buttons fit perfectly with the garment. This allows the automatic sewing machine to sew the snap buttons accurately, which helps to improve the aesthetics of the snap button sewing and thus improve the quality of snap button sewing. This device has the advantages of reasonable structural design, high degree of automation, fast sewing speed, and easy operation, and is easy to promote and use. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0013] like Figures 1-5 As shown, this utility model includes a base 1 and an automatic sewing machine 2 mounted on the base 1. The automatic sewing machine 2 is a structure used in the prior art, including a sewing head, a machine body, a table, an electrical control system, and auxiliary devices. The sewing head is the core part of the sewing machine, and it includes a needle plate, a rotary hook, a feeding mechanism, a presser foot lifting mechanism, and a needle. Because the holes on the snap fasteners are relatively small, the needles used to sew the snap fasteners need to be fine-diameter sewing needles. A snap fastener mold is installed on the base 1 below the automatic sewing machine 2. The snap fastener mold includes a movable support 3, a fixed template 4, and a movable template 5. The size of the movable template 5 is smaller than that of the fixed template 4. The movable support 3 is slidably mounted on the machine base 1. A translation driver 6 connected to the movable support 3 is installed on the machine base 1 on the side away from the automatic sewing machine 2. The fixed template 4 is fixedly mounted on the movable support 3. The movable template 5 is located above the fixed template 4, and one end of the movable template 5 is slidably connected to the movable support 3. A fixed frame is installed on the top of the movable support 3. A lifting driver 7 connected to the movable template 5 is installed on the fixed frame. The other end of the movable template 5 is machined with a snap fastener placement groove 8 that cooperates with the automatic sewing machine 2. A pressing component that cooperates with the snap fastener placement groove 8 is installed on the movable template 5.

[0014] The working process of this device is as follows: First, the garment to be sewn with snap fasteners is placed between the fixed template 4 and the movable template 5. After the garment is laid flat, the lifting driver 7 drives the movable template 5 to move down, fixing the garment onto the fixed template 4. Then, the lifting driver 7 stops working, and the snap fasteners are manually placed into the snap fastener placement slot 8. Tweezers can be used to assist in placing the snap fasteners. After the snap fasteners are placed, the pressing component presses and fixes them in place in the snap fastener placement slot 8. Then, the translation driver 6 drives the movable support 3 to move towards the automatic sewing machine 2. As the movable support 3 moves, it simultaneously moves the fixed template 4 and the movable template 5. When the fixed template 4 and the movable template 5 move to the snap fastener placement slot 8 directly below the needle of the automatic sewing machine 2, the translation driver 6 stops operating, and the automatic sewing machine 2 can then place the snap fasteners. The snap fasteners in slot 8 are automatically sewn. After the snap fasteners are sewn, the translation driver 6 drives the snap fastener mold to return to its original position, and the lifting driver 7 drives the movable template 5 to move upward and return to its original position. This allows the garment with the snap fasteners sewn to be removed from between the fixed template 4 and the movable template 5. The snap fastener mold in this device not only reduces labor intensity and increases the speed of snap fastener sewing and production efficiency, but also solves the problem of the difficulty of sewing small snap fasteners. It can significantly reduce the difficulty of snap fastener sewing and effectively improve the firmness of snap fastener sewing. At the same time, the clamping component can clamp the snap fasteners in the snap fastener placement slot 8 to prevent the snap fasteners from moving during the movement, ensuring that the snap fasteners fit perfectly with the garment. This allows the automatic sewing machine 2 to sew the snap fasteners accurately, which helps to improve the aesthetics of the snap fastener sewing and thus improve the quality of snap fastener sewing.

[0015] Furthermore, to improve the clamping effect of the snap fastener, the clamping assembly includes a telescopic rod 9, a rotating arm 10, and a clamping strip 11. A downwardly recessed mounting groove is machined on the movable template 5. The lower end of the telescopic rod 9 is fixedly installed in the mounting groove, and a connecting support 12 is installed on the top of the telescopic rod 9. The rotating arm 10 is rotatably mounted on the connecting support 12. A clamping arm 13 is obliquely installed at one end of the rotating arm 10, and the clamping strip 11 is installed at the end of the clamping arm 13 and cooperates with the button placement groove 8. A power arm 14 is obliquely installed at the other end of the rotating arm 10. The movable template 5 is equipped with... There is a drive mechanism that is connected to the power arm 14. When in use, the height of the telescopic rod 9 is adjusted appropriately according to the height of the hidden buckle in the hidden buckle placement slot 8, so as to adjust the height position of the connecting support 12, so that the position of the pressing strip 11 matches the top surface of the hidden buckle. In this way, the pressing of the hidden buckle can be achieved by using the lever principle. During this process, the drive mechanism can control the power arm 14, the rotating arm 10 and the pressing arm 13, so that the power arm 14 can move on the movable template 5. According to the lever principle, the contact area between the pressing strip 11 and the hidden buckle can be adjusted, thereby adjusting the pressing degree of the pressing strip 11 on the hidden buckle.

[0016] Preferably, the driving mechanism includes a micro motor 15, a transmission screw 16, and a wedge 17. The micro motor 15 is a structure used in the prior art, and finished products can be directly purchased according to the power required. The top surface of the movable template 5 is machined with a downwardly recessed strip groove. The micro motor 15 is installed at one end of the strip groove. One end of the transmission screw 16 is connected to the micro motor 15, and the other end is rotatably installed at the other end of the strip groove. A slider 18 is threaded onto the transmission screw 16. The wedge 17 is fixedly installed above the slider 18. The top surface of the wedge 17 is connected to the power arm 14. In use, the micro motor 15 can drive the transmission screw 16 to rotate forward or reverse. During the rotation of the transmission screw 16, it can drive the slider 18 to move back and forth along the transmission screw 16. During the movement of the slider 18, it can drive the wedge 17, the power arm 14, the rotating arm 10, and the pressing arm 13 to move back and forth, thereby adjusting the contact area between the pressing strip 11 and the snap fastener, and realizing the pressing of the snap fastener.

[0017] Preferably, the telescopic rod 9 includes a rod body and a rod sleeve. The lower end of the rod body is movably inserted into the upper end of the rod sleeve. The rod body and the rod sleeve are connected and fixed by an adjusting threaded sleeve 19. The adjusting threaded sleeve 19 is designed to prevent the rod body from rotating inside the rod sleeve. Rotation of the adjusting threaded sleeve 19 can only allow the rod body to move up and down within the rod sleeve. This facilitates the adjustment of the height of the telescopic rod 9. To ensure that the rod body always moves in a straight line within the rod sleeve, a guide slider 20 is installed at the lower end of the rod body located within the rod sleeve. The inner wall of the rod sleeve is machined with a matching guide groove, and the guide slider 20 is slidably installed within the guide groove.

[0018] Furthermore, the base 1 is machined with a transverse slide groove 21 that matches the movable support 3. The lower end of the movable support 3 is slidably installed in the transverse slide groove 21. The movable support 3 moves back and forth along the transverse slide groove 21, which enables it to maintain a linear movement state.

[0019] Furthermore, the upper end of the movable support 3 is machined with a vertical groove 22 corresponding to the movable template 5. The movable template 5 is slidably installed in the movable support 3. The movable template 5 moves back and forth along the vertical groove 22, which can keep it in a linear movement state.

[0020] Furthermore, the translation driver 6 and the lifting driver 7 are hydraulic cylinders or pneumatic cylinders. Hydraulic cylinders or pneumatic cylinders have the advantages of smooth transmission, large speed range, and sensitive action. During use, they can significantly improve the efficiency of concealed snap fastening.

[0021] Furthermore, to meet the needs for snap fastener sewing of different sizes, two sets of adjustment components are symmetrically arranged on both sides of the snap fastener placement groove 8. Each set of adjustment components includes an adjustment arc plate 23 and an elastic element 24. The elastic elements 24 are installed at equal intervals on the inner side of the snap fastener placement groove 8, and the adjustment arc plate 23 is installed at the end of the elastic element 24. The adjustment arc plate 23 is installed in the snap fastener placement groove 8 through the elastic element 24. The elasticity of the elastic element 24 can be used to adjust the diameter between the two elastic arc plates 23. By adjusting the size between the two adjustment arc plates 23, the needs for snap fastener sewing of different sizes can be met.
