Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an improved sewing machine. Background Technology

[0002] During the production and processing of wool sweaters, wool sweater sheets are knitted using a flat knitting machine, and then sewn together on a sewing machine to form the sweater. For some larger wool sweaters, when sewing on the sewing machine, the bottom of the sweater is on the ground. As the machine moves forward during sewing, the upper part of the sweater is dragged, causing deformation, especially for heavier sweaters, which affects product quality. Furthermore, when the sewing machine is operating, workers need to watch the sewing needle and place the knitted sheet onto it. During this process, short fibers may scatter, and because the operator is close to the sewing machine, these fibers can easily be inhaled, posing a health hazard. Utility Model Content

[0003] To address the aforementioned technical shortcomings, this invention provides an improved sewing machine that allows the fabric to rotate forward along with the sewing disc during actual processing, thus avoiding pulling on the fabric and affecting quality.

[0004] This utility model discloses an improved sewing machine, including a main unit and a sewing disc and sewing device mounted on the main unit. The main unit is mounted on a mounting plate. A vertically upward connecting shaft is provided on the mounting plate below the sewing disc. A turntable is mounted on the connecting shaft and contacts the mounting plate. A baffle is provided on one side of the mounting plate between the connecting shaft and the main unit. A vertically downward motor is fixed on the baffle. A drive wheel is provided at the output end of the motor. The drive wheel contacts the edge of the turntable and drives the turntable to rotate.

[0005] A dust collection hood is provided on the sewing tray, and the dust collection hood is connected to the vacuum cleaner through a pipe.

[0006] The dust hood is arc-shaped and hollow inside. An arc-shaped dust suction port is provided on the outer wall of the dust hood, and the dust suction port faces the sewing needle on the sewing plate. The dust hood is fixed to the upper surface of the non-rotating part inside the sewing plate.

[0007] The dust collection hood is provided with several dust collection pipes at intervals. One end of each dust collection pipe is connected to the hollow structure inside the dust collection hood, and the other end is connected to the dust collection pipe.

[0008] The improved sewing machine obtained by this utility model uses a turntable at the bottom to allow the fabric to be placed on the turntable and rotate forward together with the sewing disc, thereby avoiding pulling on the fabric and affecting product quality. At the same time, a dust suction hood is used to remove short fibers generated during the process of putting the fabric into the sewing needle, preventing the operator from inhaling them, making it safer.

[0010] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation

[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0012] Example 1:

[0013] like Figure 1 , Figure 2 As shown, this utility model discloses an improved sewing machine, including a main unit 1 and a sewing disc 3 and a sewing device 2 mounted on the main unit 1. The main unit 1 is mounted on a mounting plate 5. A vertically upward connecting shaft 6 is provided on the mounting plate 5 below the sewing disc 3. A turntable 7 is mounted on the connecting shaft 6 and contacts the mounting plate 5. A baffle 8 is provided on one side of the mounting plate 5 between the connecting shaft 6 and the main unit 1. A vertically downward motor 9 is fixed on the baffle 8. A drive wheel 10 is provided at the output end of the motor 9. The drive wheel 10 contacts the edge of the turntable 7 and drives the turntable 7 to rotate.

[0014] The main unit 1, sewing device 2, and sewing disc 3 of the sewing machine are all existing known structures, and their connection relationships and specific structures will not be described in detail here. The outer ring of the sewing disc 3 is equipped with sewing needles 4. The outer ring is rotated by the main unit 1. The outer ring of the sewing disc 3 and the sewing needles 4 enter the sewing device 2 for sewing, stitching the fabric pieces together. The operator aligns two fabric pieces and then slips them onto the sewing needles 4. The fabric pieces rotate forward with the sewing disc 3, while the lower end of the fabric pieces rests on the turntable 7. Under the action of the motor 9, the drive wheel 10 drives the turntable 7 to rotate. The motor 9 can be synchronously controlled by the controller of the main unit 1 to achieve synchronous and co-directional movement of the turntable 7 and the sewing disc 3. Thus, in actual processing, the lower end of the fabric piece rests on the turntable 7, and the upper end of the fabric piece is slipped onto the sewing needles 4. During rotation, the fabric pieces move synchronously up and down, effectively avoiding pulling on the fabric pieces and ensuring fabric quality. The rotating shaft is fixed between the center of the sewing disc 3 and the mounting plate 5. Since the outer ring of the sewing disc 3 rotates while its interior remains stationary, the connecting shaft 6 can be fixed between the interior of the sewing disc 3 and the mounting plate 5. The turntable 7 can be rotatably connected to the connecting shaft 6 via bearings or other structures. The lower surface of the turntable contacts the mounting plate 5 with virtually no gap between them, preventing the fabric from getting stuck and causing jamming. The drive wheel 10 at the output end of the motor 9 contacts the edge of the turntable 7, generating pressure between them. Thus, when the drive wheel 10 rotates, it drives the turntable 7 to rotate. The drive wheel 10 can be a rubber wheel.

[0015] While the sewing disc 3 and the turntable 7 are rotating, the fabric is sewn. After the sewing is finished, the baffle 8 can block the fabric to prevent it from rotating repeatedly with the turntable 3.

[0016] A dust collection hood 11 is installed on the sewing disc 3, and the dust collection hood 11 is connected to a vacuum cleaner via a pipe. During operation, the vacuum cleaner draws air out of the dust collection hood 11, creating negative pressure inside. Air from the outside of the dust collection hood 11 enters the dust collection hood 11. During this process, short fibers generated when the fabric is attached to the sewing needle 4 are carried into the dust collection hood 11 by the airflow, thus preventing the operator from inhaling them and affecting their health.

[0017] The dust hood 11 is arc-shaped and hollow inside. An arc-shaped suction port 12 is provided on the outer wall of the dust hood 11, facing the sewing needles 4 on the sewing disc 3. The dust hood 11 is fixed to the upper surface of the non-rotating inner side of the sewing disc 3. Since the area where the outer ring of the sewing disc 3 attaches to the fabric is fixed and the range is relatively stable, generally within a 90° range directly in front of the operator, short fibers are easily generated within this range when the sewing needles 4 attach to the fabric. Therefore, an arc-shaped dust hood 11 is used. The arc angle of the dust hood 11 can be greater than 90°, allowing it to face the operator directly. The suction port 12 on the dust hood 11 is elongated and directly faces the sewing needles 4 within this range. This ensures that short fibers generated at the sewing needles 4 within this range can be immediately drawn into the dust hood 11 through the suction port 12, preventing the spread of short fibers.

[0018] The dust collection hood 11 is provided with several suction pipes 14 spaced apart. One end of each suction pipe 14 is connected to the hollow structure inside the dust collection hood 11, and the other end is connected to the suction pipe 13. Three suction pipes 13 are provided on the dust collection hood 11 at intervals, which can evenly connect the dust collection hood 11 and the suction pipes 13, so that the negative pressure inside the dust collection hood 11 is uniform and stable, thereby improving the dust collection effect.
