Description

Technical Field

[0001] This utility model belongs to the field of sewing machine technology and relates to a negative pressure suction plate installation structure for a sewing machine. Background Technology

[0002] A template sewing machine refers to sewing equipment that combines garment template technology with practical applications. In this type of machine, the cut pieces in the garment template are typically positioned using a suction method, that is, the cut pieces are adsorbed onto the panel using negative pressure adsorption. For example, Chinese patent literature discloses a template machine (application number: 202321380943.2), which includes a frame. The top of the frame has a placement slot, and a suction mechanism is installed within the placement slot. The suction mechanism includes a mesh plate, a sealing cover, an air duct, and a suction adjustment component. The mesh plate is connected to the top of the placement slot, and the sealing cover is connected to the bottom of the placement slot. The bottom end of the sealing cover is connected to the air duct, and a suction adjustment component is provided on one side of the air duct. The mesh plate and the sealing cover each have several fixing holes arranged in a one-to-one correspondence, and the mesh plate and the sealing cover are fixedly connected by several bolts passing through the fixing holes.

[0003] The template machine has the following shortcomings during use: the ends of the bolts used to fix the mesh plate and the sealing cover protrude from the upper surface of the mesh plate, making the surface of the negative pressure suction plate (i.e. the upper surface of the mesh plate) uneven, which is not conducive to the flat suction of the cut pieces in the garment template, causing inconvenience to subsequent sewing operations. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a negative pressure suction plate mounting structure for sewing machines. The technical problem this invention aims to solve is addressing the issue of uneven surfaces in existing negative pressure suction plates, which hinders sewing.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A negative pressure suction plate mounting structure for a sewing machine, the sewing machine including a main table, a suction mesh plate, and a suction funnel connected to the main table. The main table has suction holes corresponding to the suction funnel. The structure is characterized by a recessed, annular stepped portion on the upper surface of the main table, located at the edge of the suction holes. A mesh pad is connected to the bottom surface of the suction mesh plate, and the mesh pad is placed on the recessed stepped portion. The suction mesh plate and the suction funnel are connected to the main table by several fasteners that simultaneously pass through the suction funnel and the mesh pad. The upper surface of the suction mesh plate is flush with the upper surface of the main table.

[0007] The negative pressure suction plate mounting structure of this sewing machine features a ring-shaped sunken step, forming a recessed groove between the sunken step and the corresponding main table. A mesh pad is connected to the bottom surface of the suction mesh plate. During use, the suction mesh plate with the mesh pad is placed on the sunken step, positioning it within the recessed groove. The upper surface of the suction mesh plate is flush with the upper surface of the main table. The suction mesh plate and suction funnel are connected to the main table by several fasteners that pass through both the funnel and the mesh pad. This design ensures the suction mesh plate is stable, maintains a flat upper surface, conceals the fasteners, and improves aesthetics. More importantly, it facilitates the smooth absorption of fabric pieces from the garment template, making sewing easier.

[0008] In the aforementioned negative pressure suction plate mounting structure of a sewing machine, the suction mesh plate and the mesh plate pad are laser-welded together. The fastener is a bolt, with the bolt head located below the main table and the bolt tail inside the mesh plate pad. Several bolts securely connect the mesh plate pad and the suction funnel to the main table, ensuring that the suction mesh plate, laser-welded to the mesh plate pad, is also securely connected to the main table. Furthermore, the bolt head being below the main table and the bolt tail being concealed within the mesh plate pad results in a smooth upper surface for the suction mesh plate, improving both aesthetics and ease of sewing. Alternatively, screws can also be used as fasteners.

[0009] In the aforementioned negative pressure suction plate mounting structure of a sewing machine, the mesh pad includes an annular outer frame and several partition strips integrally connected to opposite sides of the outer frame, with the partition strips arranged in an alternating grid pattern. The integrally formed outer frame and partition strips provide high structural strength for the mesh pad. The outer frame facilitates the fixed connection between the mesh pad and the main table plate, as well as the connection between the mesh pad and the suction mesh plate. Simultaneously, the outer frame and the alternating grid-like partition strips support the suction mesh plate, ensuring stable and aesthetically pleasing placement. The upper surface of the suction mesh plate is flat, facilitating sewing.

[0010] In the aforementioned negative pressure suction plate mounting structure of a sewing machine, the outer frame abuts against the upper surface of the recessed step. Several reinforcing ribs are integrally connected to the opposite side walls of the recessed step, and partition strips arranged parallel to the reinforcing ribs abut against the upper surfaces of the reinforcing ribs. This allows the recessed step to better support the outer frame, and the reinforcing ribs to better support the partition strips, further ensuring the stability of the suction screen and the flatness of its upper surface, facilitating sewing.

[0011] In the aforementioned negative pressure suction plate mounting structure of a sewing machine, a recessed groove is formed between the recessed step and the corresponding main table plate. The shape and size of the recessed groove match the shape and size of the suction mesh plate. This allows the sidewall of the recessed groove to limit the suction mesh plate along the circumference of the main table plate, making the suction mesh plate more stable when placed on the recessed step.

[0012] Compared with existing technologies, the advantages of the negative pressure suction plate mounting structure of this sewing machine are as follows: The negative pressure suction plate mounting structure of this sewing machine, through the setting of a ring-shaped sunken step, forms a sunken groove between the sunken step and the corresponding main table. Simultaneously, a mesh pad is connected to the bottom surface of the suction mesh plate. During use, the suction mesh plate with the mesh pad is placed on the sunken step, so that the suction mesh plate is located within the sunken groove and its upper surface is flush with the upper surface of the main table. Furthermore, the suction mesh plate and the suction funnel are connected to the main table by several fasteners that simultaneously pass through the suction funnel and the mesh pad. This ensures that the fasteners do not pass through or protrude from the suction mesh plate while still allowing the suction mesh plate to be connected to the main table. This guarantees the installation stability of the suction mesh plate, ensures a flat upper surface, conceals the fasteners, and improves aesthetics. More importantly, it facilitates the flat suction of the cut pieces in the garment template, making sewing easier. Attached Figure Description
