Description

Technical Field

[0001] This utility model relates to the field of garment processing, specifically to a hemming and sewing auxiliary device. Background Technology

[0002] Overlocking, also known as serging, is a garment finishing process that involves using an overlock machine to wrap the edges of garment pieces with overlock thread made of polyester web yarn to prevent the fabric from fraying. Because this process requires lower thread strength, the overlock thread is untwisted to save costs, resulting in a difference in material and manufacturing process compared to sewing thread (made of twisted polyester staple fibers). This process can create an elastic, wavy, lace-like edge on knitted fabrics, and when paired with bright-colored sewing thread, it can also serve a decorative function.

[0003] Currently, in the process of overlocking garments, in order to reduce manual folding of the fabric edges, a spiral-like guide tool is used to guide the fabric. However, in order to accommodate fabrics of different thicknesses, the gaps for the fabric to pass through are often designed to be relatively large. This results in the fabric being relatively loose after being guided and folded, which leads to the fabric shifting or becoming uneven when sewing, resulting in poor overlocking effect. Utility Model Content

[0004] The purpose of this invention is to provide an edge-sealing auxiliary device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hemming and sewing auxiliary device, comprising

[0007] A support mechanism includes a base, a guide plate connected to one side of the top of the base, a first curved portion on one side of the guide plate, a third curved portion on the other side of the guide plate, and a second curved portion on the bottom of the third curved portion near the first curved portion.

[0008] The hemming mechanism includes two sets of uprights symmetrically fixedly connected to one side of the top of the base. The two sets of uprights are rotatably connected to a rotating shaft inside each set of uprights. Rotating rods are symmetrically fixedly connected to the outer sides of the two sets of rotating shafts. A roller is rotatably connected between the two sets of rotating rods on the same side. A torsion spring is fixedly connected between the two sets of uprights and the rotating rods.

[0009] As a further embodiment of this utility model: one side of the base is symmetrically threaded with fixing bolts, and the outer sides of the two sets of fixing bolts are fixedly connected with multiple protruding strips in a ring array.

[0010] As a further embodiment of this utility model: two sets of the standing bases are symmetrically and fixedly connected to the side of the rotating rod, and each set of the reinforcing ribs is fixedly connected to the base.

[0011] As a further embodiment of this utility model, the base has an opening for clearance.

[0012] As a further embodiment of this utility model: a calibration strip is fixedly connected to one side of the top of the base, and the calibration strip corresponds to one side of the roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With the above-mentioned structure, the torsion spring, rotating shaft, rotating rod and roller cooperate with each other, so that the rotating rod and roller can be driven to rotate to one side of the base under the elastic action of the torsion spring. This allows the roller to press the folded fabric tightly, which effectively reduces the probability of the folded fabric becoming loose during the overlock sewing process after the fabric is folded, thereby making the overlock sewing of the fabric more uniform and flat, and thus improving the quality of the overlock sewing of the fabric.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figure 1-4 A hemming auxiliary device includes a support mechanism 1, which includes a base 101. One side of the base 101 is symmetrically threaded with fixing bolts 107. The fixing bolts 107 are used to screw onto the sewing machine table, thereby fixing the base 101. Multiple protrusions 108 are fixedly connected in a circular array on the outer sides of the two sets of fixing bolts 107. The protrusions 108 facilitate the rotation and adjustment of the fixing bolts 107.

[0023] A guide plate 102 is connected to one side of the top of the base 101. A first curved portion 103 is provided on one side of the guide plate 102, and a third curved portion 105 is provided on the other side. A second curved portion 104 is provided at the bottom of the third curved portion 105, near the first curved portion 103. The second curved portion 104 guides the fabric, allowing it to be folded twice after passing through the guide plate 102, thus reducing manual folding. An clearance opening 106 is provided inside the base 101 to allow the sewing machine's stitching mechanism to pass through, facilitating the sewing and securing of the folded fabric.

[0024] A calibration strip 207 is fixedly connected to one side of the top of the base 101. The calibration strip 207 corresponds to one side of the roller 204. The calibration strip 207 can limit and calibrate one side of the folded fabric. The hemming mechanism 2 includes two uprights 201 symmetrically fixedly connected to one side of the top of the base 101. Two sets of uprights 201 are symmetrically fixedly connected to the side of the rotating rod 203. Each set of reinforcing ribs 206 is fixedly connected to the base 101. The reinforcing ribs 206 are used to further connect and fix the uprights 201 and the base 101, thereby improving the connection stability between the uprights 201 and the base 101.

[0025] Two sets of uprights 201 are internally rotatably connected to rotating shafts 202. Rotating rods 203 are symmetrically fixed to the outer sides of both sets of rotating shafts 202. A roller 204 is rotatably connected between the two sets of rotating rods 203 on the same side. The rotating rods 203 are designed to rotate synchronously with the rotating shafts 202, and their rotation allows for adjustment of the height of the roller 204. Torsion springs 205 are fixedly connected between the two sets of uprights 201 and the rotating rods 203. The torsion springs 205 utilize their elasticity to drive the rotating rods 203 downwards, allowing the roller 204 to press the folded fabric firmly.

[0026] In use, the base 101 is fixed to the top of the sewing machine, and the clearance 106 is aligned with the sewing part of the sewing machine. Then, the side of the fabric to be hemmed is wrapped around the outside of the second curved part 104 and the inside of the second curved part 104 in sequence, so that the fabric is wrapped and folded twice. Then, the two sets of rotating shafts 202 are rotated, thereby driving the rotating rod 203 to rotate. When the rotating rod 203 rotates, it can raise the roller 204. Then, the folded fabric is passed between the roller 204 and the base 101. Then, the rotating shafts 202 are released, so that the torsion spring 205 returns to its deformation, thereby driving the rotating rod 203 to rotate, so that the roller 204 presses the fabric tightly. Then, the sewing machine can be started, so that the sewing machine can sew the folded fabric when it starts working. During the sewing process, the roller 204 can roll and press the folded fabric, so that the fabric is sewn more evenly and flat.

[0027] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
