Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a height-adjustable sewing machine for fabric processing. Background Technology

[0002] In the fabric processing fields such as garment manufacturing and home textile production, sewing machines are the core equipment for sewing and splicing fabrics. Their operating comfort and work efficiency directly affect production quality and the labor intensity of workers.

[0003] Most sewing machines have a fixed operating table height, making it difficult to adjust the table height according to the operator's height. Taller users have to bend over to accommodate the low operating table, which can easily lead to lower back and back muscle strain. Shorter users have to bend over to operate the machine, which can cause shoulder and neck fatigue after long-term work. This not only reduces work efficiency but may also lead to occupational injuries. This fixed installation design does not meet ergonomic requirements. In addition, thread and needle are high-frequency consumables in the sewing process, which requires frequent replacement. The needles are small and delicate, and when retrieving them from the accessory box, the operator has to repeatedly rummage and pick them out, which is extremely time-consuming and laborious. To address these problems, the inventor proposes a height-adjustable sewing machine for fabric processing. Utility Model Content

[0004] To address the issues of a fixed operating table height on sewing machines, making it difficult to adjust the table height according to the operator's height, and the need for operators to repeatedly rummage through the parts box when retrieving needles and thread, this invention aims to provide a height-adjustable sewing machine for fabric processing.

[0021] Example: Figure 1-5As shown, this utility model provides a technical solution: a height-adjustable sewing machine for fabric processing, including an H-shaped plate 1. Two sets of main rods 12 are symmetrically fixedly connected to the top of the H-shaped plate 1 near the center. Guide grooves are correspondingly opened on the inner wall of the main rods 12 to ensure that the lifting rods 13 rise and fall vertically without deviation. The lifting rods 13 are slidably inserted into the top of the main rods 12. An operating table 11 is fixedly connected between the tops of the two sets of lifting rods 13. The sewing machine body 16 is set on the top of the operating table 11. A storage box 4 is fixedly connected to the bottom of the operating table 11 near one corner. A second main rod 14 is fixedly connected to the top of the H-shaped plate 1 at one center. A lifting shaft 2 is slidably inserted into the top of the second main rod 14, and the top of the lifting shaft 2 is fixedly connected to the operating table 11. The storage box 4 is located in front of... A placement box 41 is slidably inserted into the end of the storage box 41. Sliders are symmetrically provided on both side walls of the placement box 41. A slide rail is correspondingly provided on the inner wall of the storage box 4 to achieve smooth pull-out. An installation box 44 is symmetrically fixedly connected to the inside of the placement box 41 near the center. Several evenly distributed arc-shaped blocks 47 are fixedly connected between the two installation boxes 44. The arc-shaped blocks 47 are used to place needles. A limiting plate 45 is slidably inserted into the top of the installation box 44. A spring 46 is symmetrically fixedly connected to the bottom end of the limiting plate 45 near the center. The bottom end of the spring 46 is fixedly connected to the inner wall of the installation box 44. The electrical components in this application are electrically connected to their compatible power supply through wires. A suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0022] Several evenly distributed positioning shafts 43 are symmetrically fixedly connected inside the placement box 41 near the mounting box 44.

[0023] The positioning shaft 43 is set inside the placement box 41 by adopting the above technical solution in order to facilitate the installation of the coil.

[0024] A light bulb 42 is fixedly connected to the inner wall of one side of the placement box 41.

[0025] By adopting the above technical solution, the second lighting lamp 42 can be powered by a battery to illuminate the inside of the placement box 41, making it easier to take out the needle and coil.

[0026] A lead screw 21 is rotatably connected at the center of the bottom end of the main rod 2 14, and the lead screw 21 is rotatably connected to the internal thread of the lifting shaft 2.

[0027] By adopting the above technical solution, after the lead screw 21 rotates, the lifting shaft 2 connected by the threaded rotation can be raised and lowered.

[0028] A bevel gear 22 is fixedly connected to the outer ring of the lead screw 21 near the bottom, and a bevel gear 23 is rotatably connected to the side wall of the main rod 24, and the bevel gear 23 meshes with the bevel gear 22.

[0029] By adopting the above technical solution, after the bevel gear 23 rotates under the action of the motor 24, the meshing bevel gear 22 can rotate.

[0030] A motor 24 is installed on the side end of the main rod 2 14 near the bottom center. The output end of the motor 24 passes through the main rod 2 14 and is fixedly connected to the bevel gear 23.

[0031] By adopting the above technical solution, the working motor 24 is started, thereby causing the fixedly connected bevel gear 23 to rotate.

[0032] A support shaft 3 is fixedly connected to the top of the operating table 11 near the corner. A wire feeding frame 31 is fixedly connected to the outer ring of the support shaft 3 near the center. A light 32 is fixedly connected to the outer ring of the support shaft 3 near the top.

[0033] By adopting the above technical solution, a lighting lamp 32 is installed on the outer ring of the support shaft 3 to facilitate work in poor environments, and the illumination angle can be adjusted.

[0034] The control panel 11 is detachably equipped with an extension plate 15 on its side.

[0035] By adopting the above technical solution, an anti-slip silicone pad can be attached to the top of the extension plate 15 so that the longer end can hang down to the ground when processing the fabric.

[0036] Working principle: When using this device, before operating the sewing machine body 16, the height of the operating table 11 needs to be adjusted according to the user's height. By starting the motor 24, the fixedly connected bevel gear 23 rotates, which in turn rotates the meshing bevel gear 22, which drives the fixedly connected lead screw 21 to rotate. Then, the threaded lifting shaft 2 drives the operating table 11 to rise under the action of the main rod 12 and the main rod 2 14, thereby realizing the adjustment of the height of the operating table 11, which is convenient for users of different heights to use, and can avoid the situation that the user will feel tired after working for a long time due to the operating table 11 being too high or too low.

[0037] When it is necessary to replace the needle, the placement box 41 at the front end of the storage box 4 can be pulled open to expose the arc-shaped block 47. Then, press the limiting plate 45 on one side to make the limiting plate 45 slide down into the mounting box 44 and squeeze the spring 46. At this time, the needle placed on the arc-shaped block 47 can be pushed to one side and taken out (the needle placed on the arc-shaped block 47 is difficult to take out due to its small size). This improves the convenience of taking out the needle.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
