Description

TECHNICAL FIELD

[0001] The utility model relates to clothing production technical field especially relates to a clothing production edge pressing device. BACKGROUND

[0002] Clothing is the general term of clothes, shoes and ornaments, and refers to clothes. In the national standard, clothing is defined as the product sewn on the human body to protect and decorate, also known as clothes. Clothing has appeared in the early stage of human social development. At that time, the ancients made some materials into rough "clothes" and wore them on their bodies. The original clothes of human beings were mostly made of animal skins, and the earliest "fabric" was made of hemp and grass fibers. To the society, clothing is a necessary product for covering and decorating the body, not only for wearing, but also for identity, life attitude and personal charm.

[0003] At present, in clothing production, the edges of clothing need to be folded and sewn, or lace is made on the edges of clothing. These all use sewing machines. In the use process of the sewing machine, the clothing fabric itself is mostly fluffy, and in the process of driving the fabric to move and complete sewing, the fabric will inevitably wrinkle due to the force. Therefore, an edge pressing device for pressing the clothing fabric is added to the sewing machine. The conventional edge pressing device is mostly a simple roller or pressing plate structure. If the pressing plate structure is used, the smoothness of the pressing plate needs to be maintained, otherwise the transmission of the fabric in the sewing process will be affected due to the friction between the pressing plate and the fabric. If a single roller structure is used, because the contact surface between the roller and the fabric is limited, only the fabric in the linear area can be subjected to pressure, resulting in low edge pressing effect.

[0004] Therefore, a clothing production edge pressing device is proposed. UTILITY MODEL CONTENT

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please see Figures 1 to 4 A garment manufacturing edge-pressing device includes a mounting plate 1, which is a strip plate. Mounting holes 2 are provided at each corner of the mounting plate 1. During use, bolts or screws can be passed through the mounting holes 2 to fix the mounting plate 1 to a sewing machine (such as a sewing machine). Figure 4 At the location indicated by the middle arrow A, in actual use, the mounting hole 2 is a strip groove set along the length of the mounting plate 1, which increases the installation range of bolts or screws, making it easier to adjust the installation position of the mounting plate 1 on the sewing machine according to the actual use, thereby improving the adaptability of the pressing device. At the same time, multiple bolts or screws can be placed in a single mounting hole 2 to improve the installation stability of the mounting plate 1.

[0026] like Figure 1 and Figure 2As shown, a support plate 3 is vertically installed at the bottom of the mounting plate 1. A U-shaped frame 5 with an opening facing downwards is provided below the support plate 3. A pushing mechanism 4 is connected to the top of the U-shaped frame 5 through a connector. The pushing mechanism 4 is fixed on the top of the support plate 3. In actual use, the pushing mechanism 4 is one of a cylinder, an electric push rod, or a hydraulic cylinder. Under the operation of the pushing mechanism 4, the U-shaped frame 5 can be driven to perform lifting and lowering operations.

[0027] Furthermore, a guide shaft 17 is provided parallel to the side of the pushing mechanism 4. The bottom of the guide shaft 17 is fixed on the U-shaped frame 5, and the other end of the guide shaft 17 slides through the support plate 3 to provide guidance for the lifting and lowering of the U-shaped frame 5, making the lifting and lowering of the U-shaped frame 5 more stable.

[0028] It should be noted that, as Figure 2 and Figure 3 As shown, the connector includes a sliding sleeve 14, which is fixed to the top of the U-shaped frame 5. A connecting shaft 15 is slidably installed inside the sliding sleeve 14. The top of the connecting shaft 15 is fixed to the pushing mechanism 4. A compression spring 16 is sleeved on the connecting shaft 15. One end of the compression spring 16 is fixed to the support plate 3, and the other end of the compression spring 16 is fixed to the sliding sleeve 14, providing an elastic connection between the U-shaped frame 5 and the pushing mechanism 4. That is, after the bottom of the U-shaped frame 5 contacts the support surface, the U-shaped frame 5 can slide upward on the connecting shaft 15, thereby compressing the compression spring 16 and generating an elastic force that reacts to the U-shaped frame 5. This can both buffer the U-shaped frame 5 during its descent and ensure the pressure of the bottom of the U-shaped frame 5 on the support surface.

[0029] When pressing the edges of the garment fabric, the pushing mechanism 4 can be operated to push the U-shaped frame 5 closer to the edge of the fabric, such as... Figure 1 and Figure 2 As shown, multiple rotating shafts 7 are provided on the inner side of the U-shaped frame 5, and the ends of the rotating shafts 7 are rotatably mounted on the connecting frame 11. The ends of the connecting frame 11 are fixed on the inner side of the U-shaped frame 5. A sprocket 8 is installed on the end of the rotating shaft 7, and a chain 9 is installed on the sprocket 8. A transmission belt 10 is installed on the outer side of the chain 9. As the U-shaped frame 5 falls, the bottom surface of the transmission belt 10 will press against the edge of the fabric, thereby pressing the edge of the fabric.

[0030] Specifically, the rotating shafts 7 are arranged in a matrix, supporting the transmission belt 10 so that its frontal projection is rectangular. That is, the bottom surface of the transmission belt 10 that contacts the fabric is a long strip. Compared with conventional rollers, the surface-to-surface contact can better apply force to the fabric, thereby improving the edge pressing effect of the edge pressing device. Furthermore, due to the rotation of the rotating shafts 7 and the transmission between the chain 9 and the sprocket 8, the transmission belt 10 also has the mobility of transmission. That is, when the fabric moves, the transmission belt 10 can also move. The large contact surface will not increase the friction and affect the movement of the fabric, ensuring that the sewing operation at the edge of the fabric can be carried out normally.

[0031] In order to improve the transmission effect of the fabric movement on the transmission belt 10, the transmission belt 10 is a rubber belt with a rough outer surface.

[0032] It should be noted that since the chain 9 is fitted onto and meshes with the sprocket 8, it is easy for the chain 9 to become loose during use. Therefore, a tensioning wheel 12 is provided on the inner top of the U-shaped frame 5. The tensioning wheel 12 is located above the transmission belt 10 and is rotatably mounted in the U-shaped seat 13. The U-shaped seat 13 is fixed to the connector, that is, the bottom of the connecting shaft 15 is fixed to the U-shaped seat 13. As the bottom surface of the transmission belt 10 contacts the fabric, the pushing mechanism 4 can continue to act downward. At this time, the connecting shaft 15 will continue to push downward, thereby acting on the tensioning wheel 12 to act on the top surface of the transmission belt 10, and causing the top surface of the transmission belt 10 to begin to concave downward, thereby deforming the transmission belt 10 and allowing the chain 9 to be tensioned.

[0033] Moreover, during this process, due to the elastic effect of the compression spring 16, the sliding of the connecting shaft 15 on the sliding sleeve 14 will not affect the effect of the transmission belt 10 on the fabric.

[0034] It should be further explained that as the fabric enters below the transmission belt 10, limit plates 6 are installed at the bottom of both ends of the U-shaped frame 5. The end of the limit plate 6 away from the U-shaped frame 5 is bent upward, that is, before the fabric enters below the transmission belt 10, it will first come into contact with the limit plate 6. As the fabric passes under the limit plate 6, the edge of the fabric at the fold will be smoothed by the limiting effect of the limit plate 6. The arc-shaped limit plate 6 also acts as a buffer for pressing the edge of the fabric to prevent the folded fabric from directly contacting the transmission belt 10 and wrinkling due to the fabric's own fluffiness.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
