Description

Technical Field

[0001] This utility model relates to the field of sewing machines, and in particular, to an auxiliary fabric feeding mechanism. Background Technology

[0002] Currently, Chinese patent CN205529367U discloses a flatbed sewing machine, including an operating table. A flatbed sewing machine base is fixedly installed on the upper surface of the operating table. A hydraulic cylinder is fixedly installed on the side wall of the machine head of the flatbed sewing machine. A limit ring is provided on the side wall of the piston rod at the lower end of the hydraulic cylinder, and a spring is sleeved on the rod wall below the limit ring.

[0003] When sewing long strips of fabric, the fabric often slips off-center due to vibrations generated by the sewing machine during its feeding process, resulting in poor sewing quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an auxiliary fabric feeding mechanism to prevent the fabric from deviating and to improve the sewing quality.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an auxiliary fabric feeding mechanism, including a support plate, a power component, a support frame and a pressure plate, wherein a limiting area for fabric limiting is formed between the support plate and the pressure plate, the support frame drives the pressure plate to move closer to the support plate through a driving component, and the support frame is driven by the power component to move closer to the sewing machine.

[0006] To achieve the above technical solution, the fabric is placed on the support plate, and the pressure plate is pressed against the upper surface of the fabric. During the sewing process, the fabric moves towards the sewing machine. At the same time, the power component is activated, and the support frame moves towards the sewing machine. Simultaneously, the drive component is activated, and the pressure plate moves towards the support plate. The pressure plate moves synchronously with the fabric, thus preventing the fabric from deviating during the sewing process and improving the sewing quality.

[0007] In a preferred embodiment of this utility model, a connecting plate is connected to the drive shaft of the drive component, and the connecting plate is connected to the pressure plate through a buffer assembly.

[0008] By implementing the above technical solution, the vibration generated during the movement of the support frame can be mitigated by the buffer component, thereby making the connection between the pressure plate and the fabric more stable.

[0009] In a preferred embodiment of this utility model, the buffer assembly includes a sliding hole, a sliding rod, and an elastic element. The sliding hole is formed on the connecting plate and / or the pressure plate. The sliding rod is connected to the pressure plate and / or the connecting plate and is slidably connected in the sliding hole. The connecting plate achieves buffering between itself and the pressure plate through the elastic element.

[0010] To achieve the above technical solution, vibration is generated during the movement of the support frame. The connecting plate moves along the length of the slide rod. Through the elastic force of the elastic element, the pressure plate and the connecting plate have a good buffering effect, so that the pressure plate maintains a relatively stable pressure on the fabric, making the fabric less likely to deviate.

[0011] In a preferred embodiment of this utility model, the support frame includes a horizontal bar and a vertical bar, the horizontal bar is connected to the vertical bar, the vertical bar is connected to the power component, an adjustment seat is provided on the horizontal bar, the adjustment seat is slidably connected to the horizontal bar along the length direction of the horizontal bar and fixed on the adjustment seat, and the adjustment seat is connected to the driving component.

[0012] To achieve the above technical solution, the adjustment seat is moved along the length of the crossbar and then fixed on the crossbar, so that the positions of the drive component and the pressure plate can be adjusted to adapt to different shapes of fabric and improve practicality.

[0013] In a preferred embodiment of this utility model, the crossbar is slidably connected to and fixed to the vertical bar along the length of the vertical bar.

[0014] The above technical solution enables the distance between the pressure plate and the support plate to be adjusted to accommodate fabrics of different thicknesses and improve practicality.

[0015] In a preferred embodiment of this utility model, the power component includes a power motor, a conveyor belt, a guide rail, and a guide slider. The vertical rod is connected to the guide slider, which rotates via the conveyor belt and moves along the guide rail toward the sewing machine. The power motor drives the conveyor belt to rotate.

[0016] The above technical solution involves starting the power motor, rotating the conveyor belt, and having the conveyor belt drive the guide slider to move along the length of the guide track. The structure is simple and the operation is convenient.

[0017] As a preferred embodiment of this utility model, it also includes a controller for controlling the power motor and the drive components.

[0018] Implementing the above technical solution can achieve fully automatic control and improve convenience.

[0019] As a preferred embodiment of this utility model, the support plate is provided with an adjustment groove, and the support plate is provided with a guide plate for contacting the edge of the fabric. The guide plate moves along the length direction of the adjustment groove and is fixed on the support plate.

[0020] To achieve the above technical solution, the edge of the fabric is brought into contact with the guide plate, which guides the direction of fabric transmission. The guide plate is then moved along the length of the adjustment groove and fixed to the support plate to accommodate fabrics of different sizes and improve practicality. Attached Figure Description

[0030] The drive assembly includes a power component 7 and a support frame 4. The support frame 4 includes a horizontal bar 41 and a vertical bar 42. The horizontal bar 41 is connected to the vertical bar 42, which is vertically positioned, while the horizontal bar 41 is horizontally positioned. The length of the horizontal bar 41 is along the width direction of the support plate 22. The vertical bar 42 is connected to the power component 7. An adjusting seat 43 is provided on the horizontal bar 41. The adjusting seat 43 is slidably connected to the horizontal bar 41 along its length and is fixed to the adjusting seat 43 with bolts. The adjusting seat 43 is connected to the drive component 5.

[0031] The driving component 5 is a cylinder. A horizontally arranged connecting plate 51 is fixedly connected to the driving shaft of the driving component 5. The connecting plate 51 is connected to the pressure plate 52 through the buffer assembly 6. The pressure plate 52 is located below the buffer assembly 6.

[0032] The buffer assembly 6 includes a sliding hole 61, a sliding rod 62, and an elastic element 63. A circular sliding hole 61 is formed in the connecting plate 51. The lower end of the sliding rod 62 is fixedly connected to the pressure plate 52, and the upper end of the sliding rod 62 is slidably connected to the sliding hole 61. The sliding rod 62 is vertically positioned. One end of the elastic element 63 abuts against the upper surface of the pressure plate 52, and the other end of the elastic element 63 abuts against the lower surface of the connecting plate 51.

[0033] The horizontal bar 41 is slidably connected to the vertical bar 42 along the length of the vertical bar 42 and is fixed to the vertical bar 42 by bolts.

[0034] The vertical rod 42 is driven by the power component 7 and moves toward the sewing machine 1.
