Description

Technical Field

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

[0002] In garment manufacturing, it's common to encounter situations where a piece of fabric needs to be folded over before being sewn to another piece. In this case, the folded piece needs to be manually folded over, then manually pressed to join with the other edge before sewing. During this process, manually lifting the edge of the folded piece while it's laid out on the worktable is sometimes difficult. It requires a tugging motion, and the process can cause the piece to shift and misalign. Furthermore, accurately positioning the folded section is not easy. Therefore, existing folding techniques are time-consuming, labor-intensive, inefficient, and lack precision. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and provide a sewing device that is suitable for quickly flipping the edge of a piece of fabric that needs to be flipped and then sewing it with another piece of fabric. The flipping is fast and accurate, which greatly improves production efficiency and processing quality.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a sewing device for sewing a first fabric piece that needs to be hemmed to a second fabric piece; characterized in that it includes:

[0006] A workbench is provided with a table surface and an adsorption unit, wherein the adsorption unit is used to adsorb objects onto the table surface.

[0007] A sewing template includes a base plate, a flip plate, and a cover plate. The base plate has a through hole, and a first side of the through hole is used to position the folded portion of a first piece of fabric. The base plate is placed on a table surface so that the edge of the first piece of fabric is lifted at the first side due to the first piece of fabric being attracted through the through hole. The flip plate is rotatably connected to the base plate, and when the flip plate flips to partially cover the through hole, it presses down on the folded portion of the first piece of fabric. The cover plate is rotatably connected to the base plate and is used to press down on a second piece of fabric located between the flip plate and the cover plate. The cover plate has a sewing groove, and the sewing groove is directly opposite the portion of the through hole not covered by the flip plate.

[0008] A sewing machine that sews the first piece of fabric that needs to be hemmed to the second piece of fabric along the sewing groove.

[0009] The second technical solution is based on the first technical solution, wherein the cover plate is rotatably connected to the base plate about a rotation axis extending along a first direction, and the first direction is parallel to the base plate.

[0010] The third technical solution is based on the second technical solution. The base plate has a limiting part at the first side, and the limiting part protrudes along the second direction, which is perpendicular to the base plate.

[0011] The fourth technical solution is based on the first technical solution. The base plate is further provided with a base plate magnet, and the flip plate is further provided with a flip plate magnet. When the flip plate presses down on the flip edge, the flip plate magnet and the base plate magnet attract each other.

[0012] The fifth technical solution is based on the first technical solution. The flip plate is further provided with a combing part, which is brush-shaped. When the flip plate is flipped to partially cover the through hole, the combing part blocks the part of the through hole that is facing the sewing groove.

[0013] The sixth technical solution is based on the first technical solution. The tabletop is provided with a number of evenly distributed holes, and the adsorption unit includes an exhaust device that communicates with the holes to create negative pressure on the tabletop.

[0014] The seventh technical solution is based on the first technical solution, and the base plate is further provided with a guide frame.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution, the workbench is provided with a table surface and an adsorption unit. The adsorption unit is used to adsorb objects onto the table surface. The sewing template includes a base plate, a flip plate, and a cover plate. The base plate has a through hole. When the base plate is placed on the table surface, the adsorption force on the table surface will cause the first piece of fabric laid on the base plate to be recessed at the through hole. The edge of the first piece of fabric is slightly raised, and the raised part is easy for the operator to grasp and fold. Since the first side of the through hole is used to position the folded part of the first piece of fabric, the positioning of the first side during the folding process ensures that the folded part is accurately positioned. The flap covers the through hole, partially pressing down on the folded part of the first cut piece. This ensures the folded part remains stable while not obstructing the portion to be sewn, thus providing space for subsequent sewing. The cover plate is rotatably connected to the base plate and presses down on the second cut piece located between the flap and the cover plate, preventing misalignment between the first and second cut pieces during sewing and improving production quality. The cover plate has a sewing groove facing the portion of the through hole not covered by the flap, ensuring sufficient space for sewing between the folded part and the second cut piece.

[0017] In the second technical solution, the base plate is rotatably connected to the base plate around the rotation axis extending along the first direction, which ensures that the cut pieces between the base plate and the cover plate can be tightly pressed by the two. After the base plate and the cover plate are connected to each other, the misalignment of the two and the misalignment of the stitching groove during the sewing process are avoided, which would affect the sewing.

[0018] In the third technical solution, in order to optimize the folding effect, a limiting part is set on the first side of the base plate near the through hole. The protrusion direction of the limiting part is perpendicular to the base plate. In this way, when the first piece of fabric covers the through hole, the adsorption force on the table causes the first piece of fabric to be recessed at the through hole. The edge of the first piece of fabric is limited by the limiting part, making it more noticeable to lift up and easier to grab and fold.

[0019] In the fourth technical solution, when the edge of the first cut piece is grasped and folded, and the flap is rotated to cover the folded part, in order for the flap to effectively keep the folded part stable, the flap needs to firmly press the folded part under the flap. For this purpose, a magnet is set on the flap, and a magnet is also set on the base plate corresponding to the position of the flap. Using the magnetic force of the magnet, the flap is affected by the magnetic force and tightly adheres to the base plate, thereby firmly clamping the folded edge of the first cut piece.

[0020] In the fifth technical solution, a combing part is provided at the flip plate. The combing part is brush-shaped and the position covered by the combing part is exactly at the part of the through hole facing the sewing groove. In this way, the combing part can enhance the stability of the flipping to a certain extent. It can cooperate with the flip plate to press down the flipping part and further maintain the stability of the flipping part. In addition, the brush-shaped combing part can continuously comb and fix the sewing thread as the needle moves up and down to ensure that the stitches are tight and reduce abnormalities such as loose threads and skipped stitches.

[0021] In the sixth technical solution, several evenly distributed holes on the workbench can ensure that the negative pressure on each through hole is consistent when negative pressure is generated, so as to ensure that the negative pressure on the cut pieces on the template is consistent.

[0022] In the seventh technical solution, in order to facilitate the accurate sewing of the first cut piece that needs to be hemmed onto the second cut piece, a guide frame line is set on the base plate, which makes it easier for operators to quickly and accurately place the second cut piece, thereby improving efficiency and production quality.

[0039] See Figure 1 , Figure 1 The overall structure of a sewing device is shown. The sewing device is used to sew a first cut piece that needs to be hemmed onto a second cut piece. The sewing device includes a workbench 1, a sewing template 4, and a sewing machine 11. The workbench 1 has a table surface 2 and an adsorption unit 3. The table surface 2 has several evenly distributed holes. The adsorption unit 3 is connected to the holes. The evenly distributed holes can ensure that the negative pressure is balanced at every point on the table surface 2. The sewing template 4 is used to cooperate with the workbench 1 to help hem the first cut piece to form a folded part 10. After the folded part 10 is fixed, the first cut piece and the second cut piece are sewn together. After all the preceding work is completed, the sewing machine 11 sews the first cut piece and the second cut piece.

[0040] See Figure 2The sewing template 4 has a base plate 5 and a flip plate 6. The base plate 5 has a through hole 8, a limiting part 13, a base plate magnet 14, a guide frame line 17, and a base plate positioning hole 18. The flip plate 6 has a flip plate magnet 15 and a combing part 16. The base plate 5 is used to place the first and second cut pieces. The through hole 8 is used for airflow to make the edge of the first cut piece slightly curl up. The limiting part 13 reinforces the scheme of making the edge of the first cut piece curl up, making the curling of the first cut piece more obvious and easier to grasp. The base plate magnet 14 is used to generate a mutual attraction force on the flip plate magnet 15. The guide frame line 17 is used to guide the correct placement of the second cut piece. The base plate positioning hole 18 is used to fix it to the sewing machine 11. The flip plate 6 is used to press down the folding part 10 and keep the folding part 10 stable. The combing part 16 is adapted to assist the flip plate 6 in pressing down the folding part 10 and cover the part of the through hole 8 facing the sewing groove 12 to comb the needle thread.

[0041] See Figure 3 The sewing template 4 is also equipped with a cover plate 7. Figure 3 The diagram shows the structure of the cover plate 7. The cover plate 7 is provided with a sewing groove 12 and a cover plate positioning hole 19. The cover plate 7 is used to press down the first cut piece. The sewing groove 12 is suitable for the sewing machine 11 to run the stitches. The cover plate positioning hole 19 is used to fix it to the sewing machine 11.

[0042] In this embodiment, the base plate 5 has a through hole 8 on its left side, the left side of the through hole 8 is the first side 9, the left side of the first side 9 has a limiting part 13, the left side of the limiting part 13 has a base plate magnet 14, the left side of the base plate magnet 14 has a flip plate 6, the flip plate 6 is rotatably connected to the base plate 5, the flip plate 6 has a flip plate magnet 15 mirror-symmetrical about the base plate magnet 14 around the rotation axis, and the flip plate 6 has a combing part 16; the cover plate 7 is rotatably connected to the base plate 5 around the rotation axis extending along the first direction. In this embodiment, the first direction is parallel to the base plate 5. When the cover plate 7 flips around the rotation axis to cover the base plate 5, the sewing groove 12 is aligned with the part of the through hole 8 that is not covered by the flip plate 6 but is covered by the combing part 16, so as to allow the sewing machine 11 to pass the thread; the cover plate 7 can firmly press the first cut piece and the second cut piece between the base plate 5 and the cover plate 7 to ensure that misalignment does not occur during sewing and improve production quality.

[0043] See Figure 4 In this embodiment, the left side of the through hole 8 is the first side 9, which is suitable for positioning the folded part 10 of the first piece. The left side of the first side 9 is provided with a limiting part 13, which protrudes along the second direction and is perpendicular to the bottom plate 5.

[0044] See Figure 5 , Figure 5 The diagram shows the process of placing the sewing template 4 on the workbench 1, placing the first cut piece on the base plate 5, turning on the adsorption unit 3, and the airflow flowing through the through hole 8 and the table surface 2 in sequence. The first cut piece is affected by the airflow and a depression is formed at the through hole 8. The edge of the first cut piece is limited and positioned by the first side 9 (limiting part 13) and slightly raised.

[0045] See Figure 6 , Figure 6 The diagram shows the structure of the limiting part 13 and the folding part 10. The first piece of fabric that needs to be folded is limited and positioned by the first side 9 and the limiting part 13, where a crease is generated. It is then grasped and folded, forming the folding part 10. The relationship between the folding part 10, the through hole 8, and the limiting part 13 is shown in the figure. The folding part 10 is used to sew together with the second piece of fabric.

[0046] See Figure 7 , Figure 7 The diagram shows the structure of the flap 6 and the folding section 10. When the folding is completed and the folding section 10 is formed, the flap 6 flips along the rotation axis and presses onto the folding section 10. At this time, the flap 6 only partially covers the through hole 8, and the uncovered through hole 8 is suitable for providing thread space for the sewing machine 11. In addition, the combing section 16 located on the flap 6 can press onto the folding section 10 together with the flap 6. The combing section 16 covers the thread space of the sewing machine 11. In this way, the sewing machine 11 can continuously pass back and forth through the combing section 16 during the sewing process to comb its own needle thread, thereby reducing loose thread and skipped stitches.

[0047] See Figure 8 , Figure 8 This is a schematic diagram of the structure of the first cut piece after the edge is grasped and folded to form the folded part 10.
