Description

Technical Field

[0001] The present invention particularly relates to a multifunctional sewing device for processing curtain hems. Background Technology

[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood sheets, and metal, and serve the functions of shading, heat insulation, and regulating indoor light. Fabric curtains are categorized by material, including cotton gauze, polyester fabric, cotton-polyester blends, cotton-linen blends, and non-woven fabrics. Different materials, textures, colors, and patterns combine to create curtains of various styles, complementing different interior design styles. In the curtain manufacturing process, the curtain's vertical edges need to be sewn together. To enhance the aesthetics of the vertical edges, gusseted strips are sewn onto both sides of the vertical edges. Each gusseted strip is then sewn with a tassel and lace. For the aforementioned multiple processes, the existing sewing device is equipped with a pull tube. From top to bottom, the pull tube has a first lace limiting groove, a first tassel limiting groove, a first gusseted strip limiting groove, a second gusseted strip limiting groove, a second tassel limiting groove, and a second lace limiting groove. One end of the fabric is passed through the corresponding limiting groove, positioned on the upper and lower sides of the vertical edge, respectively. At this point, the sewing device is activated to sew the fabric onto the vertical edge. This design reduces the number of operation steps and improves production efficiency. To accommodate fabrics of different widths, the aforementioned limiting grooves are typically set to be quite wide. After repeated use, dust or fabric scraps may accumulate on the edges of the inner wall of the limiting groove. Existing cleaning methods generally involve using a fine brush to rub against the inner wall of the corresponding limiting groove to sweep the dust out of the limiting groove. However, this cleaning method requires using a brush to clean each limiting groove individually, which is very cumbersome and the cleaning effect is not ideal. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a multifunctional sewing device for processing curtain hems.

[0004] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0005] A multifunctional sewing device for processing curtain hems, comprising:

[0006] The operating table is equipped with a machine body for sewing vertical edges. A pull box is provided on one side of the machine body. The pull box has an opening at the end near the machine body. The pull box is provided with a first lace limiting groove, a first pressing strip limiting groove, a first bud strip limiting groove, a second bud strip limiting groove, a second pressing strip limiting groove, and a second lace limiting groove from top to bottom in the vertical direction, all of which are connected to the opening.

[0007] The mounting platform is detachably mounted on an opening. A guide cavity is provided within the mounting platform, and an air inlet for connecting a ventilation source is provided on the platform. A first air guide plate and a second air guide plate are respectively inclined upwards on the bottom wall of the guide cavity. A connecting plate is provided between the first and second air guide plates, and the connecting plate is positioned directly below the air inlet. A first ventilation hole is provided on the connecting plate. A second ventilation hole is provided on both the first and second air guide plates. The diameter of the first ventilation hole is smaller than the diameter of the second ventilation hole, and a portion of the airflow passes through the second ventilation hole. Simultaneously, air is discharged into both sides of the inner wall of the first lace limiting groove, both sides of the inner wall of the first pressing strip limiting groove, both sides of the inner wall of the first budding strip limiting groove, both sides of the inner wall of the second budding strip limiting groove, both sides of the inner wall of the second pressing strip limiting groove, and both sides of the inner wall of the second lace limiting groove. Another part of the air is discharged into the middle of the first lace limiting groove, the middle of the first pressing strip limiting groove, the middle of the first budding strip limiting groove, the middle of the second budding strip limiting groove, the middle of the second pressing strip limiting groove, and the middle of the second lace limiting groove through the first ventilation hole. The ventilation volume of the second ventilation hole is greater than that of the first ventilation hole.

[0008] Preferably, the opening is provided with a slot for insertion into a mounting table.

[0009] Preferably, a silicone sleeve is fitted on the mounting platform.

[0010] Preferably, the mounting platform is provided with limit strips on both sides, and the mounting platform is provided with protrusions. When the protrusions are inserted into the slots, the limit strips abut against the edges of the openings.

[0011] Preferably, the first lace limiting groove, the first pressing strip limiting groove, the first bud strip limiting groove, the second bud strip limiting groove, the second pressing strip limiting groove, and the second lace limiting groove are all integrally formed.

[0012] Preferably, the lower end of the operating table is also provided with four support legs.

[0013] Preferably, the pull box can be fixed to the operating table with bolts.

[0014] The beneficial effects of this invention are:

[0015] This application utilizes a first ventilation hole on the connecting plate and a second ventilation hole on the first and second air guide plates. The diameter of the first ventilation hole is smaller than that of the second ventilation hole. This design ensures that when air enters the limiting groove, the ventilation volume on both sides of the limiting groove is greater than that in the middle, effectively cleaning the dead-angle areas on both sides of the limiting groove and improving the cleaning effect. Furthermore, since the outlet simultaneously connects to the first lace limiting groove, the first pressure strip limiting groove, the first bud strip limiting groove, the second bud strip limiting groove, the second pressure strip limiting groove, and the second lace limiting groove, air can clean multiple limiting grooves simultaneously, saving operation time.

[0024] A multifunctional sewing device for processing curtain hems, as shown in the reference. Figure 1-Figure 2 This includes:

[0025] The operating table 1 is provided with a machine body 2 for sewing vertical edges. A pull box 3 is provided on one side of the machine body 2. The pull box 3 has an opening 4 at the end near the machine body 2. The pull box 3 is provided with a first lace limiting groove 5, a first pressing strip limiting groove 6, a first bud strip limiting groove 7, a second bud strip limiting groove 71, a second pressing strip limiting groove 61, and a second lace limiting groove 51 that are connected to the opening 4 from top to bottom in the vertical direction.

[0026] Mounting platform 8 is detachably mounted on opening 4. Mounting platform 8 has a guide cavity 9 and an air inlet 81 for connecting to a ventilation source. A first air guide plate 91 and a second air guide plate 92 are respectively inclined upwards on the bottom wall of the guide cavity 9. A connecting plate 93 is provided between the first air guide plate 91 and the second air guide plate 92, and the connecting plate 93 is located directly below the air inlet 81. A first ventilation hole 931 is provided on the connecting plate 93. Second ventilation holes 921 are respectively provided on the first air guide plate 91 and the second air guide plate 92. The diameter of the first ventilation hole 931 is smaller than the diameter of the second ventilation hole 921, allowing a portion of the airflow to pass through... The second ventilation hole 921 simultaneously discharges air into both sides of the inner wall of the first lace limiting groove 5, both sides of the inner wall of the first pressing strip limiting groove 6, both sides of the inner wall of the first budding strip limiting groove 7, both sides of the inner wall of the second budding strip limiting groove 71, both sides of the inner wall of the second pressing strip limiting groove 61, and both sides of the inner wall of the second lace limiting groove 51. Another part of the air is discharged through the first ventilation hole 931 into the middle of the first lace limiting groove 5, the middle of the first pressing strip limiting groove 6, the middle of the first budding strip limiting groove 7, the middle of the second budding strip limiting groove 71, the middle of the second pressing strip limiting groove 61, and the middle of the second lace limiting groove 51. The ventilation volume of the second ventilation hole 921 is greater than that of the first ventilation hole 931.

[0027] Furthermore, the opening 4 is provided with a slot 41 for the mounting platform 8 to be inserted.

[0028] Furthermore, a silicone sleeve is fitted onto the mounting platform 8.

[0029] Furthermore, limiting strips 81 are respectively provided on both sides of the mounting platform 8, and protrusions 82 are provided on the mounting platform 8. When the protrusions 82 are inserted into the slots 41, the limiting strips 81 abut against the edges of the openings 4.

[0030] Furthermore, the first lace limiting groove 5, the first pressing strip limiting groove 6, the first bud strip limiting groove 7, the second bud strip limiting groove 71, the second pressing strip limiting groove 61, and the second lace limiting groove 51 are all integrally formed.

[0031] Furthermore, the lower end of the operating table 1 is also provided with four support legs 11.

[0032] Furthermore, the pull box 3 can be fixed to the operating table 1 with bolts.

[0033] The working principle of this invention is:

[0034] As an embodiment 1, this application can connect an air pump to the air inlet 81. The air pump draws air from the outside into the air inlet 81, thereby providing an air source. When it is necessary to clean the dust and lint in the limiting groove of the pull box 3, the protrusion on the mounting platform 8 is inserted into the slot 41. When the air is driven by the air pump, it will first enter the air guide cavity. Since the connecting plate 93 is located directly below the air inlet 81, the air will first gather on one side of the connecting plate 93. The diameter of the first ventilation hole 931 on the connecting plate 93 is smaller than the diameter of the second ventilation hole 921 on the air guide plate. Therefore, most of the air will be diverted to the first air guide plate 91 and the second air guide plate 92 due to the partial obstruction of the connecting plate 93. Due to the first lace limiting groove 5, the first pressure The limiting groove 6, the first budding strip limiting groove 7, the second budding strip limiting groove 71, the second pressing strip limiting groove 61, and the second lace limiting groove 51 are all connected to the opening 4. Therefore, the air passes through the second ventilation holes 921 on the first air guide plate 91 and the second air guide plate 92 and is simultaneously discharged into both sides of the first lace limiting groove 5, both sides of the first pressing strip limiting groove 6, both sides of the first budding strip limiting groove 7, both sides of the second budding strip limiting groove 71, both sides of the second pressing strip limiting groove 61, and both sides of the second lace limiting groove 51. As a result, the air blows the dust and cloth scraps on both sides of the inner wall of the limiting groove out of the limiting groove. The diameter of the first ventilation hole 931 is smaller than that of the second ventilation hole 921. Therefore, a small portion of the air will be simultaneously delivered through the first ventilation hole 931 into the middle of the first lace limiting groove 5, the middle of the first pressing strip limiting groove 6, the middle of the first budding strip limiting groove 7, the middle of the second budding strip limiting groove 71, the middle of the second pressing strip limiting groove 61, and the middle of the second lace limiting groove 51. The two sides of the aforementioned limiting grooves are... Figure 2 The side indicated by the middle arrow is the middle part of the limiting groove. Figure 2The central part refers to the area within the groove. When sewing lace, trim, or gusseted strips, the fabric moves slowly along the center of the groove as the operator pulls it. Therefore, very little dust and fabric debris accumulates in the center of the groove. Conversely, to accommodate sewing fabrics of varying widths, the groove is wider than the fabric. As the fabric moves within the groove, dust and fabric debris tend to accumulate on both sides. This application addresses this by using a first ventilation hole 931 on the connecting plate 93 and a second ventilation hole 921 on the first air guide plate 91 and the second air guide plate 92. The diameter of the first ventilation hole 931 is smaller than that of the second ventilation hole 921. This design ensures that when air enters the groove, the ventilation volume on both sides is greater than that in the center, effectively cleaning the hard-to-reach areas on both sides of the groove and improving the cleaning efficiency. In addition, since the outlet is simultaneously connected to the first lace limiting groove 5, the first pressing strip limiting groove 6, the first bud strip limiting groove 7, the second bud strip limiting groove 71, the second pressing strip limiting groove 61, and the second lace limiting groove 51, the air can clean multiple limiting grooves at the same time, saving operation time.

[0035] Based on the above technical solution, in order to allow more air to enter the limiting groove and prevent air leakage caused by the gap between the mounting platform 8 and the limiting groove, this application provides a silicone sleeve on the protrusion on the mounting platform 8. When the protrusion is installed in the slot 41, the silicone sleeve can deform accordingly to prevent gaps between the protrusion and the limiting groove and avoid air leakage.

[0036] Based on the above technical solution, the first lace limiting groove 5, the first pressing strip limiting groove 6, the first bud strip limiting groove 7, the second bud strip limiting groove 71, the second pressing strip limiting groove 61, and the second lace limiting groove 51 of this application are all integrally molded, which can make the air more concentrated to blow the dust and cloth lint in the limiting groove out of the limiting groove, thereby improving the cleaning effect.

[0037] Based on the above technical solution, the pull box 3 can be fixed to the operating table 1 with bolts.

[0038] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
